As shown in FIG. 9, the auxiliary water tank 600 is composed of a tank body 610 molded from a resin material, a water level detection sensor 620 (FIG. 6) that detects the level of washing water stored in the tank body 610, and the detection is supplied to the tank body The temperature of the washing water in 610 is constituted by an inflow temperature sensor 630 formed by a thermister as a water temperature detecting part.

The box body 610 is composed of three components including a front box 611 that constitutes the front wall, two side walls, a bottom surface, and a top surface of the box, a rear box 612 that constitutes the rear wall of the box, and an atmosphere opening portion 613 arranged on the top surface of the box body 610 Constituted. The overall shape of the box body 610 is formed by a plurality of planes composed of a front wall, a rear wall, two side walls, a bottom surface, and a top surface, and the shape of the box body 610 is substantially quadrangular when viewed from the plane. The front wall is equipped with an inclined part that retreats from the lower part to the upper part, and in a side view, it is formed into a substantially trapezoidal shape where the upper part becomes thinner than the lower part, and the cross-sectional area of the upper part of the box body 610 becomes larger than that of the lower part. The cross-sectional area is small.

Each is provided with a water inlet 601 at the lower part of the side wall of one side of the box body 610, a water outlet 602 is provided at the lower part of the rear wall of the box body 610, and an atmosphere opening part 613 arranged on the top surface of the box body 610 is provided with a connecting box body 610.

By providing the atmosphere opening port 603, the air accumulated in the box body 610 can be released to the outside, and the internal pressure of the box body 610 can be maintained at atmospheric pressure at any time.

The inside of the sub-tank 600 is maintained at atmospheric pressure at any time, so that the flow path from the downstream of the sub-tank 600 to the suction port 516d of the water pump 516, which is a variable part of the spouting water volume, can also be maintained at the atmospheric pressure. Therefore, the water pump 516, which is a variable part of the spouting water volume, can supply water without being affected by the fluctuation of the water pressure. Therefore, a stable pump function can be exerted.

On the flow path connected to the atmosphere opening port 603 of the atmosphere opening portion 613, a buffer portion 613a (Figure 10) with a large cross-sectional area of the flow path is formed, and it is equipped with the air opening port 603 when the washing water wants to accompany bubbles from the atmosphere. In the case of sudden outflow, etc., by temporarily storing the washing water in the buffer portion 613a, the function of suppressing the outflow from the atmosphere open port 603 can be suppressed.

The washing water flowing in from the water inlet 601 first flows into the lower part of the water tank 615 and rises in the water tank 615 while changing the direction of the flow due to the rectifying rib 618. At this time, when the pressure of the washing water flowing in from the water inlet 601 is high, or when the washing water contains a large amount of air and the flow is obviously disturbed, the rectifying ribs 618 can be used to moderately rectify the flow, and The vortex generated on the downstream side of the rectifying rib 618 separates the air contained in the washing water.

The air-separated washing water that has risen in the water inlet tank 615 will cross the upper end of the partition wall 614 and flow into the storage tank 616 to be stored.

At this time, even when the pressure of the washing water flowing in from the water inlet 601 is high, or when the washing water contains a large amount of air and the flow is obviously turbulent, the washing water can pass through the barrier wall 617 to suppress the upward flow, and can prevent the washing water from directly facing the atmosphere opening portion 613 and flowing out from the atmosphere opening port 603 to the outside of the sub-tank 600.

As mentioned above, the washing water flowing in from the water inlet 601 will separate the air contained in the washing water while it rises in the water tank 615, and release the separated air from the air opening 603 to the outside of the tank body 610 . Thereby, the storage tank 616 can store washing water that does not contain air, and it can be supplied to the heat exchanger 700 from the water outlet 602.

At the time P1 when the washing switch (for example, the buttocks washing switches 221, 410) of the operating unit 210 or the remote controller 400 has been operated, the control unit 130 will start to energize the water stop solenoid valve 514, and start washing water At the same time, the control unit 130 will start the driving of the water level detection sensor 620. The driving of the water level detection sensor 620 will continue until the buttocks washing stops P14.

When the water level detection sensor 620 detects the upper limit water level on P2, the control unit 130 starts time measurement, and at the time point P3 after a predetermined time has passed, stops the energization of the water stop solenoid valve 514 and stops washing Water supply. In this embodiment, the energization is stopped 2 seconds after the upper limit water level is detected.

At the time point P2 when the upper limit water level is detected, basically the auxiliary water tank 600 and the heat exchanger 700 will become full, but by supplying for an additional 2 seconds, the washing water can be more reliably filled with heat exchange The device 700 and the water pump 516 as the variable part of the spouting water amount.

As a result, since the air in the heat exchanger 700 can be eliminated and the washing water can be reliably filled with water, the heat exchanger 700 can be reliably prevented from being burnt out, and safety and durability can be improved. . In addition, by surely sending the washing water to the water pump 516 as the variable jetting water volume and forming a full water state, the water delivery function of the water pump 516 as the variable jetting water volume can be reliably activated.

The control unit 130 starts to drive the water pump 516 as the variable part of the spouting water volume at the time point P3 when the energization of the water stop solenoid valve 514 has been stopped, and activates the fluid regulating valve 517 to control the nozzle part 820 The buttocks washing flow path 835 starts to supply washing water.

By driving the water pump 516 as the variable part of the spouting water volume, the water level of the sub-tank 600 will be lowered, and at the time point P4 when the detection of the upper limit water level by the water level detection sensor 620 has been cancelled, the control unit 130 will start Drive of the heat exchanger 700. By detecting the drop in the water level, it is confirmed that the water pump 516, which is the variable part of the spouting water volume, is operating normally, and the abnormal temperature rise of the heat exchanger 700 can be prevented.

The washing water supplied to the buttocks washing flow path 835 is sprayed from the buttocks washing spray port 834. The sprayed washing water is sprayed to the inner surface of the holding portion 816 provided at the front end of the support portion 810 through the spray opening 844 to reflect and clean the outer surface of the nozzle cover 840. This cleaning action is called pre-washing. The pre-washing is performed until the temperature of the hot water discharged from the heat exchanger 700 reaches 25°C and continues until the time point P5 after 2 seconds.

When the washing before the end of time P5 is finished, the control unit 130 will start the driving of the washing nozzle driving unit 860 of the nozzle device 800 to move the nozzle unit 820 in and out from the storage position to the buttocks washing position. During the movement from the storage position to the buttocks washing position, the fluid regulating valve 517 is switched to supply washing water to the nozzle cleaning flow path 839. The washing water supplied to the nozzle cleaning flow path 839 will be sprayed from the nozzle cleaning spray outlet 838 to the inside of the nozzle cover 840. After washing the inner surface of the nozzle cover 840, the sprayed washing water will flow out from the drain port 845 to The outside of the nozzle cover 840. In the meantime, since the nozzle portion 820 can be warmed by the washing water, it is possible to prevent cold water from being sprayed during the buttocks washing to be performed later, which may cause discomfort.

The control unit 130 switches the fluid regulating valve 517 at the time point P6 when the nozzle unit 820 has reached the buttocks washing position to start the supply of washing water to the buttocks washing flow path 835. The washing water supplied to the buttocks washing flow path 835 is sprayed from the buttocks washing spray port 834, and through the spray opening 844, the part of the user is washed. The buttocks washing operation will continue until the time point P11 when the washing stop operation is performed.

During the driving of the heat exchanger 700, the control unit 130 controls the washing water to the set temperature based on the detection data of the water inlet temperature sensor 630 and the hot water discharge temperature sensor 730.

By continuing to drive the water pump 516 as the variable part of the spouting water volume, the water level of the sub-tank 600 will be lowered, and at the time point P7 when the water level detection sensor 620 detects the lower limit water level, the control unit 130 will start to check The water stop solenoid valve 514 is energized and continues to be energized until the time point P8 when the water level detection sensor 620 detects the upper limit water level.

At the time point P8 when the upper limit water level is detected, the control unit 130 will stop the energization of the water stop solenoid valve 514 and start time measurement to measure the time until the next time point P9 when the water level detection sensor 620 detects the lower limit water level. Elapsed time. At the time point P9 when the lower limit water level is detected, the control unit 130 uses the measured elapsed time and the amount of water (65cc) from the upper limit water level to the lower limit water level to perform calculations to calculate the flow rate. At the time point P10 at the end of the calculation, when there is a difference between the flow rate set for each washing intensity and the calculated flow rate, the control unit 130 adjusts the output of the water pump 516 as a variable part of the discharge water volume to Correct the flow of washing water.

At the time P11 when the operation of the operation unit 210 or the remote controller 400 to stop the washing operation has been performed, the energization of the water pump 516 and the heat exchanger 700 which are the variable part of the jetting water volume will stop, and the nozzle device 800 will be energized. The driving of the washing nozzle drive unit 860 is started, and the nozzle unit 820 is moved back from the buttocks washing position to the storage position.

At the time point P12 when the nozzle portion 820 has retracted to the storage position, the driving of the cleaning nozzle driving portion 860 of the nozzle device 800 is stopped, and the water pump 516 and the heat exchanger 700 as the variable portion of the jetting water are driven again , And start to clean the nozzle part 820 and then wash, and at the time point P13 when the predetermined time has passed, stop the driving of the water pump 516 and the heat exchanger 700 as the variable part of the jetting water volume, that is, wash after the end.

At the time point P13 when the nozzle portion 820 is cleaned, the water stop solenoid valve 514 will be energized again to supply the washing water to the sub tank 600, and at the time point P14 when the upper limit water level is detected, the water stop solenoid valve will be turned on The energization of 514 is stopped, a series of controls for buttocks washing is ended, and the sub-tank 600 is set to the state of the upper limit water level, and the washing unit is in a standby state.

Fig. 30 is a time chart showing the normal use time when the washing operation is performed in the sanitary washing device 100 that was in the standby state after the initial use was performed in the first embodiment of the present disclosure.

The obvious difference from the initial use situation shown in Figure 29 is the following points: the P20 sub-tank 600 is already full at the time of the washing operation, and the control unit 130 stores the initial use. content.

As shown in FIG. 30, in the standby state where the auxiliary water tank 600 is full, at the time point P20 when the washing switch (for example, the buttocks washing switches 221, 410) of the operating unit 210 or the remote controller 400 has been operated, The control unit 130 will start the energization of the water pump 516 to start the supply of washing water, and simultaneously start the energization of the heat exchanger 700 based on the stored data of the control that has been implemented in the initial operation. Also, the pre-washing operation of the nozzle device 800 is started at the same time. Also, the driving of the water level detection sensor 620 is started at the same time.

Different from the aforementioned initial use case, the control from the time when the cleaning operation has been performed to the time when the energization of the heat exchanger 700 is started, and the control after the time point P5 when the driving of the nozzle device 800 is started, and The action is the same.

As described above, the sanitary washing device 100 in the present embodiment has the following structure in the structure of the washing unit 500: it is not necessary to separately provide a flow sensor dedicated to detecting the flow rate, but is installed in The water level detection sensor of the auxiliary water tank 600 detects the change of the water level, and detects the flow rate by calculation. Thereby, the structure of the washing part 500 can be simplified, and cost reduction can be achieved.

In addition, the method of correcting the threshold value of the output voltage change between the electrodes in the water level detection by temperature can improve the accuracy of the water level detection and the flow rate detection, and it becomes possible to change the conductivity in a wide range. Water is used as the washing water of the sanitary washing device. Thereby, the use range and ease of use of the sanitary washing device 100 can be improved.

Moreover, in the initial use of the sanitary washing device 100, after detecting the full water state of the sub-tank 600, the water continues to flow for a predetermined time, and after the water pump is driven, the water level detection sensor has released the upper limit water level After the detection of the heat exchanger 700, the method of energizing the heat exchanger 700 is started to prevent the heat exchanger 700 from burning. As a result, compared with commonly implemented methods for preventing idling using a flow sensor, a simple structure can be used and safety and reliability can be ensured at a low cost. ＜7＞The control and action of the spray nozzle on the inner surface of the toilet

31 is a perspective view showing the appearance of the nozzle device 550 in the first embodiment of the present disclosure; FIG. 32 is a cross-sectional view of the dispersion nozzle 550; FIG. 33 is a vertical cross-sectional view showing the installed state of the dispersion nozzle 550; FIG. 34 It is a front view showing the installation state of the dispersion nozzle 550; FIG. 35 is a plan view showing the installation position of the dispersion nozzle 550 and the rotation angle of the discharge port of the dispersion nozzle 550. 36 is a graph showing the pump output in the rotation angle of the discharge port 550u of the dispersion nozzle 550 in the first embodiment of the present disclosure.

As shown in FIG. 32, the dispersion nozzle 550 is a rotating nozzle 550d in a main body 550c provided with an inlet flow path 550b. The dispersion nozzle drive part 550a as a motor is rotatably driven by an O-ring 550e and an O-ring 550f. Sealed composition. Furthermore, X-rings can be used instead of O-rings 550f to reduce the torque required for rotational drive and easily prevent fixation. The dispersion nozzle drive 550a as a motor can be made small and low. The driving part of the torque. The shaft 550n of the spreading nozzle drive part 550a is fitted in the rotating nozzle 550d.

The washing water or washing foam supplied from the inlet flow path 550b of the main body 550c passes through a plurality of inlet holes 550h cut around the rotating nozzle 550d and is discharged from the discharge port 550u.

As shown in FIGS. 34 and 35, the spreading nozzle 550 is arranged on the right side of the center of the main body 200. This is because the buttocks washing nozzle 831 or the like, which is a washing nozzle for washing the human body part, is preferentially arranged in the center, so the spreading nozzle 550 is not arranged in the center, but arranged on either side of it.

When the user enters the toilet, the control unit 130 of the sanitary washing device 100 will use the human body detection sensor 450 to detect the person entering the room, and while rotating the spray nozzle 550 in the direction of the outlet 550u, it will spread the washing foam The rotating foam spreading command in the toilet 110 is issued (foam coating) mode, and the action of spreading the rotating foam on the toilet 110 is entered, and the operation of the water pump 516 as the variable part of the water discharge volume is started, and the switch is turned on Valve 530a.

At this time, since the fluid regulating valve 517 that switches the flow paths of the buttocks washing nozzle 831, the vagina washing nozzle 832, and the nozzle cleaning unit 833 is in the closed state, the washing water from the heat exchanger 700 will be After passing through the branch flow path 530, the check valve 531, and the foam tank 532, it is discharged from the dispersion nozzle 550 toward the inner surface of the toilet 110.

At this time, the control unit 130 drives the dispersion nozzle driving part 550a of the dispersion nozzle 550 to rotate the direction of the discharge port 550u of the dispersion nozzle 550, and the washing water or washing foam discharged from the discharge port 550u is used in the toilet A water film or a foam film is formed on the inner surface of the 110.

As shown in FIG. 35, the distance from the dispersion nozzle 550 to the inner surface of the toilet 110 differs depending on the rotation angle direction of the discharge port 550u of the dispersion nozzle 550. As shown in FIG. 36, the control unit 130 controls the rotation angle of the discharge port 550u of the dispersion nozzle 550 to change the output of the water pump 516, which is a variable part of the discharge water amount.

In the sanitary washing device 100 of this embodiment, the distance to the inner surface of the toilet is the longest when the direction of the discharge port 550u of the dispersion nozzle 550 is at a rotation angle of 160°, and the direction of the discharge port 550u is 340°. The distance to the inner surface of the toilet is the shortest.

When the human body detection sensor 450 detects that the user enters the toilet, the control unit 130 will make the pump (water pump 516 as the variable part of the spouting water volume) in accordance with the rotation angle of the spouting outlet 550u of the dispersing nozzle 550 The output of is changed to the time chart shown in Figure 36.

That is, the ejection amount (and ejection speed) from the ejection port 550u is controlled so that the distance from the ejection port 550u of the dispersion nozzle 550 to the inner surface of the toilet becomes the furthest (long) rotation angle near 160°. The output of Urawa increases, and the output of the pump decreases when the distance from the outlet 550u to the inner surface of the toilet becomes near the nearest (short) rotation angle of 340°.

Therefore, when the front of the toilet that is the furthest distance from the discharge port 550u of the dispersion nozzle 550 is discharged, the washing water is discharged with the strongest force to deliver the washing water to the inner surface of the front of the toilet. In addition, when the toilet 110 that is the closest distance to the discharge port 550u of the dispersion nozzle 550 is discharged from the back, the washing water is discharged with the weakest force, so it is possible to discharge the back of the pair of toilets even if the toilet is scattered. No, to deliver the washing water or washing foam to the entire inner surface of the toilet, and to form the water film or foam film to the inner surface of the front of the toilet, so that the adhesion of dirt can be suppressed.

When the human body detection sensor 450 detects that the user enters the toilet, or by operating the operating part 210 or the spreading switch 417 of the remote controller 400, the so-called toilet foam spreading that spreads the cleansing foam to the toilet 110 can be performed.

When the control unit 130 performs toilet foam dispersion based on the above-mentioned toilet foam dispersion signal, as shown in FIG. 36, the output of the discharge water volume variable part 516 is changed, and the dispersion nozzle driving part 550a is rotated forward, and It is driven so that the direction of the discharge port 550u of the dispersion nozzle passes from the back of the toilet through the front of the toilet to the back of the toilet. After that, the control unit 130 reverses the dispersion nozzle driving unit 550a, and causes the direction of the discharge port 550u of the dispersion nozzle 550 to pass from the back of the toilet through the front of the toilet and back to the back of the toilet, and perform the foam dispersion by rotating at least once. step.

Thereby, the output of the variable part of the spouting water volume can be controlled so that the cleansing foam reaches the vicinity of the lip 110a of the toilet 110, and the cleansing foam can be scattered on almost the entire circumference of the inner surface of the toilet, and it can reach from the front of the toilet. A foam film is formed on the inner surface of the rear to inhibit the adhesion of dirt.

In this case, the following configuration can also be adopted: the control unit 130 is controlled so that as shown in FIG. 36, the output of the spouting water volume variable unit when the dispersion nozzle drive unit 550a rotates in the normal direction becomes a ratio of the dispersion nozzle drive unit Lower output during 550a reversal, and spit out cleansing foam.

By the way, as long as the output of the variable discharge volume is increased, the force of spitting out the cleansing foam will be increased, and the spray nozzle 550 will spread to a farther part, and as long as the output of the variable discharge volume is reduced, the discharge and washing will be discharged. The strength of the foam will be weakened and spread from the spreading nozzle 550 to a closer location.

With this, as shown in the dotted line as shown in Figure 35, when the direction of the outlet 550u of the spray nozzle is a forward rotation driven by a back-and-forth rotation, the cleansing foam will be spread on the lip of the toilet 110 compared to the lip of the toilet 110. The side closer to the inside draft. In addition, as shown in the dotted line in FIG. 35, when the direction of the spray outlet 550u of the spray nozzle is reversed by a back-and-forth rotation drive, the cleansing foam will be spread on the side close to the lip of the toilet 110.

Thereby, in the initial stage of dispersing, the draught surface of the upper part of the discharge port of the toilet 110 can be covered with cleansing foam, and the cleansing foam can be spread on almost the entire circumference of the inner surface of the toilet close to the lip, and it can be reached in front of the toilet. A foam film is formed on the inner surface of the rear and prevents dirt from adhering.

Furthermore, the installation position of the dispersing nozzle 550, as shown in FIGS. 2, 33, 34, and 35, is located in front of the main body 200 installed on the toilet 110. In addition, since the spray nozzle 550 is provided on the front side of the front end position of the cleaning nozzle 831 in the nozzle device 800, the spray nozzle 550u can be rotated in the direction of the discharge port 550u to perform even behind the toilet. The foam is scattered, and a foam film can be formed on the inner surface of the front to the back of the toilet, and the adhesion of dirt can be inhibited.

In addition, in the above description, although forward rotation means rotating to the right when viewed from above in FIG. 35, reverse rotation means rotating to the left, but forward rotation means rotating to the left, and reverse rotation means rotating to the right. Rotation is also possible. To put it simply, the direction in which the discharge outlet 550u of the dispersion nozzle starts to rotate during dispersion is called forward rotation, and the direction of return is called reverse rotation.

Furthermore, in the above description, although the control is configured to change the output of the water pump 516, which is the variable part of the spouting water volume, when the washing foam is dispersed in the rotating foam in the toilet 110, the original The disclosure is not limited to this. When rotating foam is dispersed, even if the output of the water pump 516, which is the variable part of the spouting water volume, is not changed, the spray nozzle 550 can be configured as described below to form foam on the inner surface from the front to the back of the toilet. Membrane, and inhibit the adhesion of dirt.

As shown in FIG. 33 and FIG. 34, the spray nozzle 550 is installed in the main body 200 so that the rotation axis Ax of the discharge port 550u of the spray nozzle 550 which is rotationally driven may incline in the front-back direction and the left-right direction. The inclination in the front-rear direction is that the lower side of the rotation axis Ax is inclined toward the front side of the toilet 110, and the inclination in the left-right direction is that the lower side of the rotation axis Ax is inclined toward the washing nozzle 831 side. With this configuration, the distance from the discharge port 550u of the dispersion nozzle 550 to the spreading position becomes longer. When the discharge port 550u faces the front of the toilet 110, the direction of the discharge port 550u becomes higher, and the washing can be reduced. The net foam is spread to the vicinity of the lip in front of the toilet 110. On the other hand, when the distance from the discharge port 550u of the dispersion nozzle 550 to the spreading position becomes closer and the discharge port 550u faces the back of the toilet 110, the direction of the discharge port 550u is lowered.

In addition, when the distance from the spraying port 550u of the spray nozzle 550 to the spraying position becomes slightly farther, and the spray port 550u faces the left side of the toilet 110, the direction of the spray port 550u will be slightly higher, and the washing foam can be removed. Spread to the vicinity of the lip on the left side of the toilet 110. When the distance from the spout 550u of the spreading nozzle 550 to the spreading position becomes slightly closer and the spout 550u faces the right side of the toilet 110, the direction of the spout 550u becomes slightly lower. .

In this way, when the washing foam is dispersed from the spray nozzle 550 to the rotating foam of the toilet 110, the spray nozzle driving unit 550a can rotate the direction of the discharge port 550u of the spray nozzle 550 with the rotation axis Ax as the center. Although the distance from the discharge port 550u of the dispersion nozzle 550 to the inner surface of the toilet can be changed with the rotation of the dispersion nozzle 550, it is because the rotation causes the height of the discharge port 550u of the dispersion nozzle 550 to change while spraying the washing foam Therefore, it is possible to spread the trajectory in the form of the dashed arrow to the left in Figure 35, forming a foam film on the inner surface near the lip from the front to the back of the toilet, and it can be used from the front to the back of the toilet. The surface inhibits the adhesion of dirt.

Furthermore, because the rotating foam is spreading with a fixed output that does not change the output of the water pump 516 that is the variable part of the spouting water volume, the rotating foam in the right direction will be spread as a pair. The trajectory of the dashed arrow in the left direction is the same for the reverse direction.

By the way, in this embodiment, the rotation axis Ax of the discharge port 550u of the dispersion nozzle 550 is shown in FIG. 33, and the inclination angle β (the angle relative to the vertical direction) in the front-rear direction is 20 degrees; as shown in FIG. 34 The inclination angle γ in the left and right directions (the angle relative to the vertical direction) is 10 degrees. In addition, the height position of the discharge port 550u of the dispersion nozzle 550 is set to be lower than the upper end surface of the toilet 110 regardless of the rotation position.

As described above, it is sufficient to configure the control unit 130 to change the output of the water pump in accordance with the rotation angle of the discharge port 550u of the dispersion nozzle 550, even if the distances to the front, side, and back of the toilet are different, It is also possible to spit out the washing water or washing foam into a wider area on the inner surface of the toilet, and form a water film or foam film on the inner surface of the toilet to inhibit the adhesion of dirt.

Furthermore, a level switch capable of adjusting the output level (average level) of the above-mentioned water pump to a higher or lower level can also be provided on at least one of the operating part 210 and the remote controller 400. In this way, even if the size of the toilet 110 is different, the washing water or washing foam can be spit out to reach the entire inner surface of the toilet, and a water film or foam film can be formed on the inner surface of the front of the toilet to inhibit the adhesion of dirt .

As mentioned above, in addition to making the control unit 130 change the output of the water pump in response to the rotation angle of the spray nozzle 550's discharge port 550u, the control unit 130 can also be set to respond to the rotation angle of the spray nozzle 550's discharge port 550u to make the dispersion The speed of the nozzle driving part 550a is changed. By changing the output of the pump (the water pump 516 as the variable part of the water ejection volume), the ejection force can be changed, so that it can spread to the inner surface of the toilet that is far away, and can suppress the inner surface of the closer toilet. In addition to scattering, the speed of the dispersion nozzle driving portion 550a can be changed according to the rotation angle of the discharge port 550u to further make the dispersion density more even.

That is, when the discharge port 550u of the dispersion nozzle 550 is rotated at a fixed rotation speed, the dispersion density will become looser at a position farther from the inner surface of the toilet, and the distance from the inner surface of the toilet is Farther parts will make the dispersion density denser.

Although the output of the pump (water pump 516, which is the variable part of the spray water volume) is changed, the dispersion distribution can be formed evenly, but by changing the speed of the dispersion nozzle drive part 550a in accordance with the rotation angle, it is possible to change the speed of the dispersion nozzle drive part 550a. It is possible to spit out the inner surface of the toilet more evenly (in other words, without omission).

For example, when the rotation angle shown in FIG. 35 is used for explanation, the rotation angle of 160°, which is the furthest distance from the discharge port 550u of the discrete cloth nozzle 550, is used to spread the washing water or washing foam in front of the toilet 110 When dispersing and discharging to the front of the toilet where the dispersion density becomes thinner, the dispersion nozzle 550 can be made to rotate at the slowest speed to increase the dispersion density. On the other hand, when it is made to discharge behind the toilet at a rotation angle of 340° which is the closest distance to the discharge port 550u of the discrete cloth nozzle 550, it can be diluted by making the dispersion nozzle 550 the fastest rotation speed. Spread density. In this way, the distribution of the washing water or washing foam scattered on the inner surface of the toilet can be more evened, and the adhesion of dirt can be suppressed.

That is, the control unit 130 can change the speed of the dispersion nozzle driving unit 550a according to the rotation angle of the discharge port 550u of the dispersion nozzle 550, so that the direction of the discharge port 550u of the dispersion nozzle 550 is the distance to the inner surface of the toilet. When the rotation angle of the front of the toilet is longer, the speed of the dispersion nozzle drive 550a is set to be low, and when the distance to the inner surface of the toilet is the rotation angle of the back of the toilet, the dispersion nozzle drive 550a is set The speed is set to be larger. In this way, even if the distances to the front, side, and back of the toilet are different, the washing water or foam can be spit out of the inner surface of the toilet without any omission, and it can be even more without omission to the inside of the front of the toilet. A water film or a foam film is formed on the surface and prevents the adhesion of dirt.

The control unit 130, after detecting the entry of a human by the human body detection sensor 450, disperses the so-called toilet foam in which the washing foam is dispersed on the inner surface of the toilet from the dispersing nozzle 550, the dispersing nozzle driving unit 550a is used to disperse the so-called toilet foam. The rotating nozzle 550d is driven back and forth at least once, and automatically stops after the foam is dispersed.

With this action, when the user enters the toilet room, the foam film can be formed on the inner surface of the toilet before use, and the adhesion of dirt can be suppressed. Furthermore, as long as it is a structure that can perform the number of times of spreading over the inner surface of the toilet and stop it from the rotating discharge port 550u, it is not limited to the structure of the above-mentioned one-time rotation drive, and it can be used. The user is allowed to select and set the number of round trips when the toilet foam is dispersed through at least one of the operating part 210 or the remote controller 400.

When the spray nozzle 550 spreads washing water or washing foam on the inner surface of the toilet, as shown in FIG. 36, the rotating nozzle 550d of the spray nozzle 550 is formed to rotate back and forth. Thereby, the rotating nozzle 550d of the spray nozzle 550 is not made to rotate only in either the right direction or the left direction, and the spray direction of the washing water or washing foam can always be the same direction. And by rotating it back and forth, the scattering from the reverse direction caused by the back and forth can be formed, and the scattering from the two directions caused by the forward and reverse rotation can further reduce the so-called scattering omissions, and can Make it easier to spread throughout. Therefore, it is possible to suppress the adhesion of dirt with a small number of spreads (time).

In the time chart of Fig. 36, it is shown that the rotation angle of the back side of the toilet is equivalent to 0° to the rotation angle of 340°, and the forward rotation is temporarily stopped. After that, the rotation angle is from 340° to the rotation angle of 0°. Reverse rotation is the action of stopping after rotating back and forth.

The rotating nozzle 550d of the dispersing nozzle 550 is provided with a rotation restricting portion (not shown) that restricts the rotatable range from a rotation angle of 0° to a rotation angle of 340° with a mechanical stopper.

The rotation restricting portion (not shown) is configured such that when a protrusion formed on a part of the outer periphery of the rotary nozzle 550d rotates together with the rotary nozzle 550d and abuts against the rotation restricting wall of the main body 550c, it can be used as a dispersion nozzle drive unit. If the motor of 550a wants to rotate the rotating nozzle 550d, the motor will slip and run idly due to mechanical abutment, and the rotating nozzle 550d will not be able to rotate.

In this way, by providing a rotation restricting portion that restricts the rotation range, the dispersion nozzle 550 can be rotated back and forth within the rotation range not restricted by the rotation restricting portion, so that the reverse direction of the dispersion caused by the back and forth can be performed, and by The spread from two directions caused by the forward and reverse reversal can reduce the so-called spreading omissions, and can be spread more easily throughout, so the adhesion of dirt can be suppressed with a smaller number of spreads (time).

In addition, since the dispersion nozzle driving part 550a is constituted by a motor, and the dispersion nozzle driving part 550a can be made to perform the origin identification of the rotation position at the position where the rotation restriction part has contacted, the accuracy of the rotation angle and the rotation speed can be improved. And can form a dispersion with very little uneven dispersion.

Furthermore, as explained in the water circuit configuration of FIG. 6, the branch flow path 530 in the washing water supply flow path 690 which is branched between the water pump 516 and the fluid regulating valve 517 as a variable part of the spouting water amount , Is connected through the on-off valve 530a and the check valve 531 so that washing water can be supplied to the foam tank 532, and a spray nozzle 550 is connected downstream of the foam tank 532. Furthermore, a lotion tank 533 for supplying lotion and a lotion pump 534 are connected to the foam tank 532, and an air pump 535 is provided for sending air into the foam tank 532 to produce washing foam.

When the control unit 130 opens the on-off valve 530a, the washing water from the heat exchanger 700 can be delivered by the water pump 516, which is a variable jet water quantity, and the washing water or washing foam can be jetted from the spray nozzle 550. At this time, according to the increase or decrease of the output of the water pump (pump) 516 and the air pump 535 which are the variable part of the discharge water volume, the discharge volume of the washing water or washing foam discharged from the spray nozzle 550 can be increased or decreased. , And the force of spitting out (spitting speed and spitting pressure).

In addition, the branch flow path 530 is provided with the on-off valve 530a, and the branch flow path 530 and the washing water supply flow path 690 may be provided with a flow path switching valve.

It can be formed that the user can select and instruct the spray nozzle 550 to spray the washing water or spray the washing foam through at least any one of the operation part 210 of the main body 200 and the remote controller 400.

It is a structure in which a foam tank 532 for supplying lotion and generating washing foam is provided between the on-off valve 530a and the spray nozzle 550, and the washing foam is discharged from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet. As a result, the inner surface of the toilet is not only a water film formed by the dispersion of water or warm water, but also a foam film caused by the washing foam containing lotion, which can further improve the inhibition The effect of dirt adhesion.

In addition, the foam film created by the cleansing foam containing the lotion can suppress unpleasant odors and improve the comfort of the visually clean impression.

In the sanitary washing device 100 of this embodiment, the washing water or washing foam is spread on the inner surface of the toilet from the spreading nozzle 550, in addition to when the human body detection sensor 450 detects the entry of a person, it can also be used Spreading is performed by operating the operation part 210 or the spreading switch 417 of the remote controller 400.

Thereby, when there is concern about dirt, a foam film composed of washing foam containing lotion can be formed to clean the toilet 110 at any time.

Furthermore, as to whether the spray nozzle 550 should spray the washing water or the washing foam on the inner surface of the toilet, the user can be allowed to use the spray selection switch (not shown) of at least one of the operation part 210 or the remote control 400 in advance to Choose arbitrarily.

In addition, the control unit 130 has a washing order issuing mode that can be selected and instructed by at least one of the operation unit 210 and the switch button of the remote controller 400. In the washing command issuance mode, the control unit 130 is configured to open the on-off valve 530a while stopping the lotion pump 534 supplying the lotion from the lotion tank 533 of the foam generating part 560 to the foam tank 532, and then open the on-off valve 530a. The spray water variable part 516 sends the washing water to the foam tank 532 and sprays it from the spray nozzle 550.

Thereby, the path from the foam box 532 to the spreading nozzle 550 can be rinsed with washing water to prevent clogging of the path and the spreading nozzle 550 due to the fixation of the lotion, and the spreading nozzle 550 from the fixation of the lotion. Caused by poor rotation, etc. In addition, the inner surface of the toilet can be flushed.

That is, since the lotion pump 534 is in a stopped state during this flushing operation, the foam tank 532 is supplied with washing water without supplying lotion. Therefore, the path from the foam tank 532 to the spreading nozzle 550 can be flushed with the washing water, and the inner surface of the toilet can also be washed with the washing water.

In addition, although it is possible to use washing water without temperature control during this washing operation, it is possible to control the temperature of the washing water sent from the heat exchanger 700 to about 40°C to obtain more Superior flushing effect.

In order to set the washing command issuing mode, the user can operate the washing switch 223 of the operation unit 210 to perform washing at any time.

Furthermore, in the vicinity of the flushing switch 223 of the operating unit 210 for setting the above-mentioned washing command issuing mode, a washing lamp 223a such as an LED (FIG. 4) is installed, and the control unit 130 is set to perform the previous operation. After washing, when a predetermined time of, for example, 20 days has elapsed, the configuration that the washing lamp 223a can flash automatically can prevent forgetting to rinse.

When the spray nozzle 550 is used to spread the cleansing foam on the inner surface of the toilet, it can also be made that the control unit 130 will respond to the rotation angle of the spray outlet 550u of the spray nozzle 550, which is similar to the situation shown in the aforementioned pump output in Figure 36. Similarly, the output of the air pump 535 is changed. Thereby, even if the distances to the front, side, and back of the toilet are different, the cleansing foam can be discharged to reach the entire inner surface of the toilet, and a foam film can be formed even on the inner surface of the front of the toilet to inhibit dirt adhesion.

That is, when the distance from the outlet 550u of the dispersing nozzle 550 to the inner surface of the toilet becomes near the furthest (long) rotation angle of 160°, the output of the air pump 535 is set to be larger, which can make The air pressure of the air pump 535 becomes higher, and the strength of the washing foam to fly far away from the outlet 550u is increased. On the other hand, when the distance from the outlet 550u to the inner surface of the toilet becomes near the nearest (short) rotation angle of 340°, the output of the air pump 535 is set to be small, so that the air pump 535 can be made The air pressure becomes lower, which weakens the force that makes the washing foam fly out. In this way, the cleansing foam can be spit out of the inner surface of the toilet without any omission.

In addition, it is equipped with a dirt detection unit (not shown) that detects dirt on the toilet 110 with image elements, etc., and the control unit 130 can move back and forth on the part where the dirt remains and spread it in a concentrated manner, thereby further improving Dirt suppression effect. Furthermore, in addition to the local back and forth method in the dirt part, the discharge port 550u of the spreading nozzle 550 can also be rotated at a low speed when rotating through the dirt part, or the pump output can be increased. ＜8＞The control and action action of the spray nozzle in the open and non-seat state of the toilet seat

Hereinafter, when a male urinates, the user is not seated on the toilet seat 300 and the toilet seat 300 is opened almost vertically, and the operation part 210 or the spreading switch of the remote controller 400 is operated.

At this time, since the user is in a standing posture and the toilet seat 300 is in an open state, the signal of the toilet seat opening and closing detection unit 331 is the toilet seat open state, and the signal of the seating detection unit 330 is the non-seat state.

When the user presses the dispersing switch 417, as shown in FIG. 37, the control unit 130 rotates the dispersing nozzle driving part 550a until the direction of the discharging nozzle 550u of the dispersing nozzle 550 is toward the position of the toilet discharge port 115 (in this In the embodiment, as shown in the graph of FIG. 37, the rotation angle of the discharge port 550u is around 20°), and the spreading nozzle driving unit 550a is stopped. After that, the discharge water variable portion 516 is controlled with a medium output, and the arrow shown in FIG. 37 discharges the cleansing foam toward the toilet discharge port 115 for a predetermined time (8 seconds in this embodiment). The cleansing foam that has been spit out will become a state covering the upper water surface of the drain port 115 of the toilet 110 (that is, the so-called upper part of the draft surface of the toilet 110).

In contrast to the rotating foam dispersing command issuing (foam application) mode of the control unit 130 described in the above item <7>, it is the direction of the discharge port 550u of the rotating spray nozzle 550 and the washing foam is spread to the toilet. The rotating foam distribution inside, in this section <8>, the fixed foam distribution command issuance (splash suppression) mode of the control unit 130 is performed while maintaining the direction of the discharge port 550u of the dispersing nozzle 550 fixed. The washing foam is spread to the fixed foam in the toilet 110.

As described above, the following situation can be assumed: for example, when a male urinates, the user is not seated on the toilet seat 300 and the toilet seat 300 is almost vertically opened, and the operating part 210 or the remote controller 400 is operated. A manual splash suppression switch 434 as a scattering switch. At this time, as shown in FIG. 37, the control unit 130 rotates the dispersion nozzle driving unit 550a until the direction of the discharge port 550u of the dispersion nozzle 550 is toward the back of the toilet (in this embodiment, as shown in the graph of FIG. 37) The rotation angle of the ground discharge port 550u is around 20°), and the spreading nozzle driving unit 550a is stopped. After that, the discharge water variable part 516 is controlled with a high output, and the arrow shown in FIG. 37 discharges the cleansing foam toward the back of the toilet for a predetermined time (8 seconds in this embodiment).

At this time, the discharge port 550u of the dispersion nozzle 550 is as shown in the cross-sectional view of FIG. 33, with respect to the rotation axis of the dispersion nozzle 550: Ax, opens in the direction of an angle α degree behind, so it will be directed toward the discharge port of FIG. 33 Direction: When the direction of Ac(b) is stopped and fixed, the cleansing foam is discharged.

In this way, after rotating and driving so that the direction of the discharge port 550u of the dispersing nozzle 550 is toward the back of the toilet, the discharge amount variable part 516 is controlled with a high output, so the washing foam can be formed quickly and the drain in the toilet is covered with foam. The state of the water surface at the upper part of the outlet 115 and the upper part of the water line in the toilet. Therefore, the odor and the adhesion of dirt near the water surface of the toilet can be suppressed by the washing foam. In addition, when the urine falls near the water surface in the toilet, the cushioning effect of the foam covering the water surface can suppress the rebound to the surroundings. In other words, by rapidly and massively dispersing foam in the direction in which the dispersing nozzle 550 has been fixed, and foam is formed on the upper part of the water surface in the toilet 110, the bounce and scattering of urine can be prevented.

Furthermore, in the present embodiment, when the male urinates, when the user operates the manual splash suppression switch 434 of the remote controller 400, the control unit 130 enters the fixed foam dispersion command issuance (splash suppression) mode and rotates the dispersion nozzle drive Until the direction of the discharge port 550u of the dispersing nozzle 550 is toward the position of the toilet discharge port 115, the dispersing nozzle driving part 550a is stopped. In addition, although it is configured to control the discharge water volume variable part 516 with high output later to discharge the cleansing foam toward the back of the toilet, the position where the cleansing foam is fixed and dispersed may be near the discharge port 115. Any position of the front side, center, and back side of the toilet.

That is, by forming a state where the draught surface and the upper part of the toilet water line are quickly covered with foam within a few seconds after starting to spit the cleansing foam, the bounce and scattering of urine can be suppressed, and the draught in the toilet 110 can be suppressed Dirt adheres to the vicinity of the thread and above it.

In addition, in the release (splash suppression) mode by the fixed foam spreading command, the washing foam is spread into the fixed foam spreading of the toilet 110 while keeping the direction of the spout 550u of the spreading nozzle 550 fixed, as shown in Fig. 37 Among them, it is configured to control the discharge amount variable part 516 with a relatively high output to discharge the cleansing foam toward the discharge port 115 of the toilet 110. However, similar to the rotating foam dispersion described in the above item <7>, the output of the water pump 516 as the variable part of the spouting water volume may be a fixed output that does not change, that is, when the fixed foam is spread The output of the water pump 516, which is the variable part of the spouting water volume, is set to the same output state as when the rotating foam is dispersed.

As described above, the sanitary washing device of this embodiment is provided with the main body 200 installed in the toilet 110, the washing nozzle 831 for washing the human body, the foam generating part 560 for generating washing foam, and spitting washing water or washing to the inner surface of the toilet. Spreading nozzle 550 for clean foam, variable part (water pump 516) that can change the flow rate of washing water sent to the spreading nozzle, and spreading nozzle drive part 550a that rotates and drives the direction of the spout 550u of the spreading nozzle . In addition, it is provided with an on-off valve 530a for opening and closing the water passage to the spray nozzle 550, a control unit 130 for controlling these operations, and an operation unit 210 (or remote controller 400) for setting the control unit 130.

In addition, the control unit 130 has: a rotating foam dispersing command issuance (foam application) mode, which rotates the spray nozzle 550 in the direction of the outlet 550u and disperses the washing foam in the toilet 110; and fixed foam dispersing command issuance ( In the splash suppression) mode, the washing foam is dispersed in the toilet while keeping the direction of the discharge port 550u of the spray nozzle 550 fixed.

With such a configuration, when the spray nozzle 550 is used to spread the cleansing foam on the toilet 110 of the toilet bowl, the spray nozzle 550 can be rotated in the direction of the outlet 550u, while the cleansing foam can be spread widely in the toilet. It can be delivered to the ground, and a foam film can be formed on the inner surface from the front to the back of the toilet, and the adhesion of dirt on the inner surface of the toilet and near the waterline can be suppressed. In addition, with the fixed foam dispersing command issuing mode in which the direction of the discharge port 550u of the dispersing nozzle 550 is kept fixed, the washing foam can be quickly formed on the upper surface of the water in the toilet 110 by the fixed foam dispersing command issuing mode in which the washing foam is dispersed in the toilet. , And the water surface above the discharge port 115 in the toilet 110 is covered with cleansing foam. Thereby, it is possible to suppress the unpleasant odor when urinating and the scattering caused by splashing when the male urinates by the cleansing foam.

In addition, the results of verification experiments on the scattering suppression effect caused by splashing in men's urination showed that the following situation can be confirmed: As shown in Figure 49, starting from the foam thickness as the foam height of about 5mm, compared with The non-foam condition will have an improvement effect. When the thickness of the foam becomes about 10mm, the suppression effect will become significant. In other words, it is more desirable that the lower limit of the foam thickness on the water surface in the toilet 110 caused by the dispersion of the foam is 5 mm or more, and the upper limit is 50 mm or less. Furthermore, 50mm or less is the upper limit of the height of the foam used to prevent the accumulated foam from reaching the buttocks when the user sits on the toilet seat.

In addition, in the sanitary washing device 100 of this embodiment, the dispersion nozzle 550 is installed in the main body 200 such that the rotation axis Ax of the discharge port 550u of the dispersion nozzle 550 that is rotationally driven is inclined in the front-rear direction and the left-right direction. In addition, the inclination in the front-rear direction is a configuration in which the lower side of the rotation axis Ax is inclined toward the front side of the toilet 110, and the inclination in the left-right direction is a configuration in which the lower side of the rotation axis Ax is inclined toward the washing nozzle 831 side.

With this, when the toilet foam of the toilet 110 is spread from the spray nozzle 550 to the toilet 110, when the distance from the spray outlet 550u of the spray nozzle 550 to the spray position becomes longer, the spray outlet 550u faces the front of the toilet. The direction of the discharge port 550u becomes higher when the spray nozzle 550u to the spreading position becomes closer. When the discharge port 550u faces the back of the toilet, the direction of the discharge port 550u becomes lower. .

In this way, it is possible to spread the washing foam while changing the height of the spray nozzle 550u according to the distance from the spray nozzle 550u to the inner surface of the toilet 110, and when the rotating foam is sprayed, even if it is not used as the spray volume The output of the water pump 516 of the variable part is changed, and a foam film can also be formed on the inner surface from the front to the back of the toilet to inhibit the adhesion of dirt.

In addition, in the sanitary washing device 100 of this embodiment, when the rotating foam is sprayed from the spray nozzle 550 to the toilet 110, the control unit 130 rotates the spray nozzle driving unit 550a forward so that it causes the spray nozzle of the spray nozzle 550 to rotate. The direction of 550u is from the back of the toilet through the front of the toilet to the back of the toilet. Next, the control unit 130 reverses the dispersing nozzle driving unit 550a so that the direction of the discharging nozzle 550u passes from the back of the toilet through the front of the toilet and back to the back of the toilet, and at least one back-and-forth rotation is performed to perform the rotating foam dispersion. step.

With this, when the washing foam is sprayed from the spray nozzle 550 to the rotating foam of the toilet 110, the control unit 130 rotates the spray nozzle driving unit 550a forward so that the direction of the spray nozzle 550u is moved from the back of the toilet. Go through the front of the toilet and reach the back of the toilet. After that, the control unit 130 reverses the spreading nozzle driving unit 550a so that the direction of the discharge port 550u of the spreading nozzle 550 moves from the back of the toilet to the front of the toilet and back to the back of the toilet for at least one back-and-forth rotation drive. In addition, the output of the variable part of the spouting water amount is controlled so that the cleansing foam reaches the vicinity of the lip of the toilet 110. Thereby, the cleansing foam can be spread on almost the entire circumference of the inner surface of the toilet, and a foam film can be formed on the inner surface from the front to the back of the toilet to inhibit the adhesion of dirt.

In addition, the sanitary washing device 100 of this embodiment is further provided with a human body detection sensor 450 that detects the entry and exit of a user into and out of the toilet room, and the control unit 130 is configured to detect that the user goes into the toilet room by the human body detection sensor 450 When entering, the rotating foam is spread on the toilet 110 by at least one of the aforementioned back-and-forth rotating motions.

Thereby, when the human body detection sensor 450 detects that the user enters the toilet room, it can complete the rotation of the spray nozzle 550u in the direction of at least one back and forth rotation and spray the washing foam on the inner surface of the toilet 110. The foam is scattered, and a foam film can be formed on the inner surface of the toilet before use to prevent the adhesion of dirt.

In addition, the sanitary washing device 100 of the present embodiment is provided with a foam tank 532 in which washing water is sent by the spray water variable part 516 by opening the on-off valve 530a by the control part 130, and the washing agent tank 533 is used for washing.

In addition, it is a structure to discharge the washing water or washing foam of the foam tank 532 from the spray nozzle 550.

With such a configuration, not only water or warm water can be spit out to the surface of the washing nozzle 831 or the inner surface of the toilet, but also washing foam containing lotion can be spit out. Thereby, the cleaning effect and the effect of suppressing the adhesion of dirt can be improved. In addition, the unpleasant odor can be suppressed by the cleansing foam containing lotion, and the visually clean comfort can be improved.

In addition, in the sanitary washing device 100 of the present embodiment, the control unit 130 has a washing command issuing mode, and in the washing command issuing mode, the configuration is as follows: when the foam tank 532 is supplied to the foam tank 532 with the detergent tank 533 of the foam generator 560 In the state where the lotion pump 534 of the lotion is stopped, the on-off valve 530a is opened, and the washing water is delivered to the foam tank 532 by the spouting water volume variable part 516, and is spouted from the spray nozzle 550.

With such a configuration, the path from the foam tank 532 to the spreading nozzle 550 is washed by the washing water, and clogging caused by the fixation of the lotion in the route and the spreading nozzle 550 and the spreading nozzle 550 can be prevented. Poor rotation caused by the fixation of the lotion. In addition, the inner surface of the toilet can be flushed.

Furthermore, in this embodiment, although a motor is used as the dispersing nozzle drive unit 550a, it may be configured as another driving source, for example, by the function when the washing foam is discharged from the discharge port 550u of the dispersing nozzle 550. The spreading nozzle 550 is rotated.

In addition, a spray nozzle 550 for spraying washing foam near the lip of the toilet 110 and a spray nozzle 550 for spraying washing foam near the discharge port 115 of the toilet 110 may also be provided. These plural dispersing nozzles 550 may be independent to make them rotate, or they may be linked to make them rotate.

In addition, the spray nozzle 550 may be provided with a discharge port 550u for spraying washing foam near the lip of the toilet 110 and a discharge port 550u for spraying washing foam near the discharge port 115 of the toilet 110.

In this embodiment, although the spreading nozzle 550 is configured to spread at two locations near the lip of the toilet 110 and near the discharge port 115 of the toilet 110, it may be configured in addition to the vicinity of the lip of the toilet 110, and In addition to the vicinity of the discharge port 115 of the toilet 110, it is spread in other locations.

Moreover, as shown in FIGS. 34, 38, and 39, the sanitary washing device 100 of this embodiment has a sleeve cover 250 integrally provided to protrude from the front side of the main body 200. In addition, it is constituted by providing a sleeve cover 217 and a lotion level confirmation window 216. The sleeve cover 217 is provided in front of the operation part 210 arranged on the upper part of the sleeve cover 250. The lotion level The confirmation window 216 is the lotion box 533 which is a transparent or translucent container inside the sleeve cover 217 and the foam generating part 560 is built in the foremost part of the sleeve cover 250, and can be seen in front of the sleeve cover 250 Visually confirm the lotion level position of the lotion tank 533.

With this configuration, the user can easily visually confirm the remaining amount of lotion before going to the sanitary washing device 100, so that the lotion can be replenished before the lotion is used up.

In this way, the lotion tank 533 with the lotion injection port 537 provided with the lotion tank cover 536 above can be arranged at the foremost part in front of the operation part 210 of the sleeve cover 250, and located in front of the toilet The nearest location, so it can be easily refilled with lotion. In addition, by arranging the lotion tank 533 with the lotion injection port 537 at the foremost part of the operation part 210 of the sleeve cover 250, it is possible to open the sleeve cover 217 ahead of the operation part 210 and use When the lotion injection port 537 replenishes the lotion into the lotion tank 533, it prevents the lotion from being spilled on the operation part 210.

In addition, as shown in FIGS. 38 and 39, since the height position of the lotion injection port 537 is a lower position than the operation part 210, when the lotion is replenished to the lotion tank 533, it can be more prevented. The situation where lotion is spilled on the operation part 210.

In addition, in the sanitary washing device 100 of this embodiment, the lotion pump hose 561 shown in FIGS. 6 and 38 is used to conduct lotion from the outlet side of the lotion pump 534 to the foam tank 532 The inside of the inlet side is a hollow cylindrical tube, and it is formed by a so-called double tube covered with a tube on the outer side of the tube. In addition, the inner diameter of the lotion pump hose 561 is smaller than the inner diameter of the foam tank hose 562 that conducts the washing foam from the foam tank 532 to the spray nozzle 550.

With such a configuration, even if the high pressure from the washing pump 534 acts, the lotion pump hose 561 can be prevented from being greatly expanded and broken, and the washing foam can be stably dispersed from the spray nozzle 550. .

Furthermore, in the sanitary washing device 100 of this embodiment, the lotion pump hose 561 with a double tube structure is formed by covering the outer side of an elastomer resin tube with a heat shrinkable tube. It is composed of dual tubes, but the material is not limited to these. Even with other materials, the double tube can still be formed to prevent swelling and rupture, and can stably disperse the washing foam from the dispersing nozzle 550.

Also, as can be seen from FIGS. 2, 39, and 40, the sanitary washing device 100 of this embodiment has a main body 200 having a control unit 130, a spray nozzle 550, a nozzle device 800, and the like inside a main body cover 202 covers the front surface of the rear body cover 201.

Moreover, the dispersion nozzle 550 is arranged in the front part of the rear body cover 201, and the front and upper part of the dispersion nozzle 550 are covered by the body cover 202, and the discharge port 516e at the lower part of the dispersion nozzle 550 is opened to the inner surface of the toilet. To set the shape (Figure 40).

Furthermore, FIG. 40 is a cross-sectional view showing the center portion of the dispersion nozzle 550 provided in the rear body cover 201 cut in the front-rear direction in the first embodiment of the present disclosure.

The cleansing foam discharged from the discharge port 516e of the dispersing nozzle 550 is usually discharged toward the inner surface of the toilet as shown by the dotted line T in FIG. 40. However, in the manner of flushing by the aforementioned washing command issuing mode, when washing water without foam is discharged from the spout 516e of the spray nozzle 550 without the detergent, there will be something as shown in Fig. 40 As indicated by the two-dot chain line S, there is a possibility that the jet flow is diffused and scattered, and scattered outside the toilet to wet the floor.

On the other hand, in the sanitary washing device 100 of the present embodiment, as shown in FIG. 40, the body cover 202 is formed with a scatter guard 550z, and the scatter guard 550z removes the air from the discharge port 516e of the dispersion nozzle 550 The upward jet that exceeds the upper limit is blocked by the wall and falls into the toilet 110. With this scattering guard 550z, the washing foam and washing water discharged from the dispersion nozzle 550 can be prevented from being sprayed out of the toilet 110, and can be dispersed in the toilet 110.

That is, a part of the main body cover 202 of the main body 200 covering the front and upper parts of the dispersion nozzle 550 has a part that blocks the upward jet from the discharge port 550u of the dispersion nozzle 550 that exceeds the upper limit, and drops into the toilet. The scattering protection part 550z can prevent the washing foam and washing water discharged from the dispersion nozzle 550 from being sprayed out of the toilet 110.

In addition, the scattering protection portion 550z formed in the main body casing 202 can not only prevent the washing foam and washing water discharged from the dispersion nozzle 550 from being sprayed out of the toilet 110. The sanitary washing device 100 has a structure in which the main body 200 can be attached to and removed from the toilet 110 through the main body fixing plate 240 (FIG. 43). When the builder or user first installs the toilet 110, and when the user removes the main body 200 from the toilet 110 and wants to clean the dirt near the lower part of the main body 200, there will be a sanitary wash that has been removed. The case where the body 200 of the cleaning device 100 is temporarily placed on a pedestal or floor.

In this way, even when the main body 200 of the sanitary washing device is temporarily placed on the pedestal or on the floor, the discharge port 516e of the dispersion nozzle 550 located on the lower side than the installation surface of the main body 200 can be scattered by scattering The protection part 550z is protected from contact with the pedestal or the floor, and can prevent damage to the spreading nozzle 550. Figure 41 is a front view of the main body 200, and Figure 42 is a side view of the main body 200. The two-dot chain line shows the surface of the pedestal when the main body 200 is placed. As shown in FIG. 41 and FIG. 42, by the scattering prevention part 550z, the discharge port 516e of the dispersion nozzle 550 does not touch the surface of the pedestal.

Furthermore, in the sanitary washing device 100 of the present embodiment, although the scatter guard 550z is formed on the main body cover 202, the scatter guard 550z may be formed on the main body 550c of the spray nozzle 550, etc. .

43 is a perspective view of the main body cover 201 behind the main body fixing plate 240 and the main body 200 in the first embodiment of the present disclosure.

In addition, the perspective view of the rear main body cover 201 is a diagram in which the control unit 130, the dispersion nozzle 550, and the nozzle device 800 provided inside are omitted for the convenience of description.

The main body fixing plate 240 is fixed to the toilet 110 by inserting a mounting bolt (not shown) through the long hole 241 for position adjustment. Also, align the main body fixing plate 240 with the center of the main body 200, and make the rear part of the main body fixing plate 240 float slightly, and then slide the main body 200 from the toilet surface until it makes a "click" sound and push it in. The body 200 is fixed to the toilet 110 by a ratchet mechanism.

In addition, when the main body 200 is removed from the toilet 110, the main body attaching and detaching button 242 located beside the main body 200 is pushed into the depth with a finger, and the main body 200 is pulled out to be removed.

Also, as shown in FIG. 43, a magnet 243 is embedded in the body fixing plate 240 made of resin, and the rear body cover 201 is installed to detect whether the body 200 has been installed in the toilet 110 or whether the body has been installed 200. The sensor 244 is detached from the toilet 110.

The mounting and dismounting sensor 244 is composed of a reed switch, and is shown in a partial cross-sectional view of FIG. 44. The state that the body 200 has been installed on the toilet 110 can be achieved by making the magnet 243 of the body fixing plate 240 and The mounting and dismounting sensor 244 of the rear main body cover 201 becomes the opposite positional relationship to detect. In addition, when the main body 200 is removed from the toilet 110, the magnet 243 is separated from the detachable sensor 244, and the detachable sensor 244 detects the detached state.

The control unit 130 is configured to not execute the discharging operation by the spray nozzle 550 when it is detected by the detachment sensor 244 that the main body 200 is detached from the toilet 110. Thereby, when the main body 200 is removed from the toilet 110, even if the manual foam application switch 433 of the remote control main body 401 or the manual splash suppression switch 434 is pressed to instruct the discharge operation by the dispersion nozzle 550, the dispersion The discharge operation performed by the nozzle 550 is also not executed. Therefore, it is possible to prevent undesirable conditions such as accidentally spraying the washing foam on the floor and people.

In addition, the control unit 130 is configured to not prohibit the discharge from the buttocks washing nozzle 831 and the vagina washing nozzle 832 even when it is recognized by the detachment sensor 244 that the main body 200 has been detached from the toilet 110. Running. In this way, in the event of a malfunction of the mounting and dismounting sensor 244 and a misrecognition that the main body 200 has been detached from the toilet 110, it can also be implemented as a basic function of the sanitary washing device 100 and for the user Very important buttocks washing and genitals washing.

Fig. 45 is a time chart when rotating foam is spread in the sanitary washing device 100 in the first embodiment of the present disclosure.

When the manual foam application switch 433 of the remote controller body 401 is pressed, at the time point N2 shown in Figure 45, the lotion pump 534 is reversed for 2 seconds and then starts to rotate forward at the time point N3 , And the water pump 516 and the air pump 535 are operated to supply lotion, water, and air to the foam tank 532 to generate washing foam. The generated cleansing foam is spread on the inner surface of the toilet 110 from the outlet 550u of the spreading nozzle 550. By spreading the rotating foam on the inner surface of the toilet, it is difficult for dirt to adhere to the inner surface of the toilet, and it is easy to remove the dirt.

At this time, the discharge port 550u of the dispersion nozzle 550 can be rotationally driven by the dispersion nozzle drive part 550a as a stepping motor. The discharge outlet 550u of the spray nozzle 550 is shown in the time chart of Fig. 45 from the stop position at the time point N3 to the limit position at the time point N6. From the limit position to the stop position at the time point N9, the bubble spreads and returns while reversing. Then, at the time point N11, the operation of the water pump 516 and the air pump 535 is automatically stopped, and the spraying of the rotating foam is automatically ended.

Furthermore, between N3 and N11 where the rotating foam is dispersed, the control unit 130 will continuously operate the water pump 516 and the air pump 535. In contrast, the lotion pump 534 performs intermittent operation in such a way that it stops after rotating forward from N3 to N4, stops after rotating forward from N6 to N7, and stops after rotating forward from N9 to N10.

According to experiments, compared to the continuous operation of the lotion pump 534 in the rotating foam dispersion, the intermittent operation can make the mixture of lotion, water, and air more ideal, and can generate more stable washing foam. In this way, the lotion pump 534 can be intermittently operated during the rotating foam spreading to generate stable washing foam. In addition, the unnecessary use of lotion can be prevented, and the labor of lotion supply can be reduced.

Furthermore, in the sanitary washing device 100 of this embodiment, the lotion pump 534 is set to operate for 2 seconds in a 6-second cycle under intermittent operation.

In addition, in the time chart when the rotating foam is spread as shown in FIG. 45, although the graph of the heat exchanger 700 is drawn with a dotted line, it shows that when the rotating foam is spread, the water pump 516 When the water supplied to the foam tank 532 has a temperature lower than 20° C., it is heated by the heat exchanger 700 so that the water temperature becomes approximately 20° C. and then supplied to the foam tank 532. When the water temperature is low, the foaming property will decrease. However, by setting the heat exchanger 700 so that the water temperature is about 20° C. and supplying it, better cleaning foam can be generated in the foam tank 532.

In addition, in the time chart at the time of performing the rotating foam spreading shown in FIG. 45, the lotion pump 534 is reversed in N2 to N3 before the time point N3 when the rotating foam spreading starts. This is because: the tube pump is used in the lotion pump 534, and on the part of the tube that has been flattened by a roller, the previous reversal is used to make the lotion on the outlet side of the tube The liquid reverses to return the squashed part to a cylindrical shape and then rotates forward, so that a stable amount of lotion can be sent out.

In addition, in the time chart when the rotating foam is spread as shown in FIG. 45, from the time point N11 to the time point N14 when the spraying of the rotating foam ends, the spreading nozzle drive unit 550a is driven from the stop position to the point of contact with the origin. After the rotation detection micro switch is pressed and the origin position of the dispersion nozzle driving part 550a as a stepping motor is recognized, it is driven and controlled by the control part 130 to return to the stop position.

In this way, by the origin reset operation of the dispersion nozzle drive portion 550a, even if the stepping motor of the dispersion nozzle drive portion 550a has a slip phenomenon due to some increase in the rotation load, etc., it is impossible to follow the driving step. Rotational driving with a forward number causes a deviation in the amount of rotation, and it is also possible to correctly reset the stop position of the rotating foam dispersion as the starting position to start the driving. That is, it is possible to always perform rotating foam spreading at a stable position.

In addition, by the rotation detection micro switch that is pressed by the reset operation of the dispersion nozzle driving portion 550a, it is possible to detect that the lotion is fixed around the discharge port 550u of the dispersion nozzle 550 for some reason. Even if the rotation detection micro switch is pressed, the rotation cannot be driven. In other words, when the rotating foam has been spread, when the signal to press the rotation detection micro switch cannot be obtained, the above-mentioned washing lamp 223a, which should be urged to perform the washing operation by the washing switch 223, can be turned on and notified. .

In the sanitary washing device 100 of the present embodiment, the time from the time N3 when the spray of the rotating foam starts to the time N12 when the spray ends of the rotating foam is set to about 15 seconds. This about 15 seconds can be adapted to the size of the toilet 110, and can be changed to about 10 seconds, about 25 seconds, etc. according to the amount of accumulated foam.

With respect to the spin bubble spreading time set here, when the time until the rotation detection micro switch is pressed is delayed by about 10% or more, the washing lamp 223a will flash in a "flicker" and "flash" repeatedly flashing way. The lamp is displayed, and the washing switch 223 is urged to be pressed to instruct the washing operation. In the washing operation, the washing water heated to about 40°C by the heat exchanger 700 flows out, and washing is performed for about 3 minutes. With this washing operation, the foam generating portion 560 and the dispersion nozzle 550 can be rinsed with washing water to prevent the lotion from fixing and clogging the foam generating portion 560, the dispersion nozzle 550, etc., and stable foam dispersion can be performed.

When the spray nozzle 550 becomes hard due to the hardening of the lotion, the action becomes worse, and the time until the rotation detection micro switch is pressed is delayed by about 20% or more relative to the set spin bubble spraying time. The lamp 223a lights up and displays with "flashing, flashing", "flashing, flashing" twice repeatedly, to urge the pressing of the washing switch 223 to perform the washing operation, and to clean the discharge port 550u of the dispersing nozzle 550 with a toothbrush or the like nearby.

In addition, in the time chart at the time of rotating foam dispersion shown in Fig. 45, the flow path switching chart shows the following action: At the time point of N2~N3, the water circuit in Fig. 6 is taken as the water bank. The supply destination of the washing water of the Uranose Water Discharge Variable Unit 516 is switched from the nozzle device 800 side to the foam generating unit 560 side, and at the time of N11~N13, from the foam generating unit 560 side to the nozzle device 800 side.

That is, at the time point of N2~N3, the control unit 130 will close the fluid regulating valve 517 and open the on-off valve 530a, and at the time point of N11~N13, it will close the on-off valve 530a and open the fluid regulating valve 517. Furthermore, instead of the on-off valve 530a, a flow path switching valve may be arranged at the branch location where the washing water supply flow path 690 is branched to the branch flow path 530, and the flow path switching valve may be used to switch the flow path. .

In addition, FIG. 46 is a time chart during the washing operation in the sanitary washing device 100 according to the first embodiment of the present disclosure.

When the washing switch 223 of the operating unit 210 is pressed and the control unit 130 enters the washing command issuing mode, the supply destination of washing water will be switched from the nozzle device 800 side to the foam generating unit 560 at the time point of N2~N3 side. Then, within about 2 minutes from the time point N3 to N8, the lotion pump 534 will remain in the stopped state as it is, so that the washing water that has been heated to about 40°C with the heat exchanger 700 can be used as a water pump The variable part 516 of the spouting water amount is conveyed to the foam tank 532 and spouted from the spreading nozzle 550.

In addition, in about 1 minute from N8 to N10, in addition to the washing water that has been heated to about 40°C, the air pump 535 of the foam box 532 is also operated to flush and clean.

In this way, during the washing operation of flushing washing, firstly, only washing water is delivered, and the air pump 535 is activated in the middle to apply air and perform washing. As a result, since most of the lotion components remaining in the foam tank 532 and the flow path can be expelled from the spray nozzle 550 quickly and efficiently by the washing water, and then the force of the bubbles caused by the air pump 535 is also effective. It is added so that even a small amount of residual amount of lotion ingredients is also washed away, so effective washing can be carried out in a short time.

When the 3 minutes of rinsing and washing up to the time point of N3~N10 are over, the standby action is performed in N10~N14 to make the lotion pump 534 reverse and forward, so that the rotating foam and the fixed foam can be spread normally. The washing operation ends automatically.

Fig. 47 is a time chart when the fixed foam is spread in the sanitary washing device 100 according to the first embodiment of the present disclosure.

When the manual splash suppression switch 434 of the remote controller body 401 is pressed, the lotion pump 534 is reversed for 2 seconds at the time point N2 shown in FIG. 47, and then starts to rotate forward at the time point N3, and the water is running The pump 516 and the air pump 535 supply lotion, water, and air to the foam tank 532 and generate washing foam.

The generated cleansing foam will be spread from the outlet 550u of the spreading nozzle 550 to the inner surface of the toilet 110. By spreading the fixed foam on the inner surface of the toilet, the foam can be accumulated on the water surface of the toilet 110 to prevent the male from urinating splashing.

The time chart when the fixed foam is spread as shown in Fig. 47 is different from the time chart when the rotating foam is spread as described in Fig. 45 in the following points: The spray nozzle driving unit 550a rotates and drives the direction of the discharge port 550u. When the fixed foam is spread, the spray nozzle driver 550a does not rotate the direction of the discharge port 550u, but keeps the fixed foam spreading. . The timing chart of FIG. 47 is the same as the timing chart of FIG. 45 except for the same, and the repeated description with that of FIG. 45 is omitted.

In addition, regarding the origin position, stop position, and limit position of Figs. 45 to 47, for example, in Fig. 37, the origin position is 0 degrees (just behind), and the stop position is 20 degrees (direction). (Clockwise) position, and the limit position is 340 degrees (clockwise). However, the present disclosure is not limited to this. For example, the origin position may be 5 degrees (clockwise from directly behind), and the stop position may be 60 degrees (clockwise from directly behind). And the limit position is 300 degrees (clockwise).

When the fixed foam is being dispersed in Fig. 47, when the command of the fixed foam is issued, the spraying nozzle driving part 550a stops the direction of the discharge port 550u at the stop position about 60 degrees clockwise from directly behind. And immediately carry out fixed foam distribution. As long as the spray nozzle drive unit 550a is driven so that the direction of the discharge port 550u is in a standby state at a position of about 60 degrees, which is the stop position, in this way. After the fixed foam is instructed to be sprayed, it can be sprayed. When the nozzle 550 is not moving, it immediately spit out cleansing foam on the inner surface of the toilet, so as to quickly form the foam height required for splash suppression on the water surface in the toilet before the male starts to urinate.

In particular, by setting the direction of the discharge port 550u in the stop position to be at, the washing foam that faces the inner surface of the toilet and hits the inclined surface can flow down toward the water surface to rotate 50~ on the inner inclined surface of the toilet. At 70 (about 60) degrees, it can quickly form cleansing foam on the entire water surface.

In addition, in the sanitary washing device 100 of this embodiment, the rotating foam distribution illustrated in FIG. 45 can be set not only when the manual foam application switch 433 of the remote controller body 401 is pressed, but also after use (that is, the toilet). After use), the rotating foam spreads automatically. In addition, it can also be set to automatically spread the rotating foam at regular intervals. After the toilet is used, or at regular intervals, it is automatically spread by rotating foam, which can make it more difficult for dirt to adhere to the inner surface of the toilet, and it is easier to remove the dirt.

In addition, by automatically spreading the rotating foam at regular intervals, the dirt near the water line in the toilet 110 can be suppressed, especially ring-shaped dirt.

In the sanitary washing device 100 of this embodiment, when the automatic operation of rotating foam spreading after the toilet is used is set to be in progress, when the user stands up from the toilet seat 300, it will be detected by the seating sensor 330, and the After 60 seconds, spin foam spreading for about 15 seconds. When a male who is not sitting on the toilet seat urinates, when the toilet seat 300 is closed, the seat opening and closing sensor 331 will be detected, and after about 60 seconds, the rotating foam will be dispersed for about 15 seconds.

In addition, the above-mentioned about 60 seconds can be set and changed to about 10 seconds, 25 seconds, etc. by the switch of the remote control main body 401. Thereby, the time from when the user stands up from the toilet seat to when the rotating foam starts to spread can be increased or decreased to a time that suits the user's way of use.

In addition, the spraying time of the rotating foam is about 15 seconds, which can be set and changed to 10 seconds, 25 seconds, etc. by the switch of the remote controller main body 401. Thereby, the amount of foam accumulated can be increased or decreased according to the size of the toilet 110.

In addition, in the sanitary washing device 100 of this embodiment, the fixed foam spreading described in FIG. 47 can be set to be automatic not only when the manual splash suppression switch 434 of the remote control body 401 is pressed, but also when the toilet seat 300 is turned on. The fixed foam is spread on the ground. After the toilet seat 300 is opened when the male urinates, the fixed foam is dispersed automatically, which can prevent the male from urinating splashing.

In the sanitary washing device 100 of this embodiment, the automatic operation of fixed foam dispersing when the toilet seat 300 is opened is in progress. When the toilet seat 300 is opened, the fixed foam dispersing is performed for about 15 seconds immediately after the toilet seat 300 is opened. .

Furthermore, the above-mentioned fixed foam dispersing time of about 15 seconds can be set and changed to 10 seconds or 25 seconds by the switch of the remote control body 401. Thereby, the amount of foam accumulated can be increased or decreased according to the size of the toilet 110.

Fig. 48 is a diagram showing the configuration of automatic operation for selecting and setting fixed foam spreading and rotating foam spreading in the first embodiment of the present disclosure.

Every time the automatic selection setting switch 236 of the operation part 210 is pressed, a preference setting can be selected. Next to the automatic selection setting switch 236 are arranged an automatic rotating dispersion lamp 236a after use, an automatic rotating dispersion lamp 236b every fixed period of time, and an automatic fixed foam dispersion indicator lamp 236c when the toilet seat is turned on. When the setting switch 236 is selected, the setting can be changed for the three types of automatic operation in the direction indicated by the arrow in FIG. 48.

After use, the automatic rotating diffuser lamp 236a, the automatic rotating diffuser lamp 236b at regular intervals, and the automatic fixed foam diffuser indicator lamp 236c when the toilet seat is turned on are all in the off state. H0 indicates three types of automatic operation. Any one of them is "off". "The status. When the automatic selection setting switch 236 is pressed once in this state, it will be in the H1 state in which only the automatic rotating scattering lamp 236a is lit after use.

In this way, every time the automatic selection setting switch 236 is pressed, the setting can be shifted to H2, H3...H6, and any one of the three types of automatic operation at H7 is in the "on" state. In addition, in the light indicator display in Fig. 48, the ○ mark indicates that the light is off and the state is set to "off", and the mark ● indicates that the light is on and the state is set to "on".

For example, in Fig. 48, in the case of setting H2, H4, H6, and H7 for the automatic operation of rotating foam spreading at regular intervals, the rotating foam shown in the time chart of Fig. 45 can be spread. It is automatically executed every about 3 hours to suppress dirt near the water line in the toilet 110, especially ring-shaped dirt.

Furthermore, the above-mentioned about 3 hours can be set and changed to every about 6 hours, every about 12 hours, or every about 24 hours by the switch of the remote control body 401, and can be configured as desired. The number of automatic operations during long periods of absence can be reduced for the convenience of the user. (Second Embodiment)

Fig. 51 is a perspective view of the sanitary washing device 1000 in the second embodiment of the present disclosure.

The sanitary washing device 1000 of the second embodiment is a so-called toilet-integrated sanitary washing device in which the toilet 110 and the main body 200 are integrated.

The sanitary washing device 100 of the first embodiment is a so-called additional type sanitary washing device in which the main body 200, which is a separate entity from the toilet 110, is installed on the toilet 110 later.

In the sanitary washing device 1000 of the second embodiment, similarly to the sanitary washing device 100 of the first embodiment, it is also provided with a structure for performing a foam spreading operation.

The sanitary washing device 1000 of the second embodiment differs from the sanitary washing device 100 of the first embodiment in that it has a flush valve (not shown). The flush valve is used in the toilet. The post-urination flush switch 910 or the post-defecation flush switch 920 of the remote controller 400 as the operating part can be used for flushing the toilet after urination or flushing the toilet after urination.

H1, H4, H5, H7 shown in Figure 48, after a predetermined time after use, set the automatic operation of the foam as shown in Figure 45, you can set the flush switch 920 after stool The amount of foam spreading on the inner surface of the toilet during operation is more than the amount of foam spreading when the flush switch 910 is operated after urination, so that it is more difficult to adhere to toilet dirt after defecation, which is easy to get dirty.

As in the first embodiment, when the main body 200 is added to the sanitary washing device 100 of the toilet 110, if the signal for flushing the toilet 110 fails to enter the control unit 130, the control unit 130 will not be able to obtain the flushing or flushing after urination. Signal information for flushing after bowel movements. Therefore, it is impossible to change the amount of automatic foam distribution after the toilet is used according to the size of the toilet.

The sanitary washing device 1000 of the second embodiment is configured to include a post-urine flush switch 910 and a post-fecal flush switch 920 on the remote controller 400 as the operating unit, so that the control unit 130 is activated based on the signal The automatic foam spreading amount after using the toilet can be changed. In addition, the control unit 130 is configured to set the amount of foam spread on the inner surface of the toilet bowl when the post-urine flush switch is operated to be larger than that during the post-urine flush switch operation. Thereby, it is possible to make it more difficult to adhere to toilet dirt after stool that is easily soiled. With this method, it is possible to more appropriately spread the foam according to the use situation without wasting lotion, and to realize the sanitary washing device 1000 in which dirt is difficult to adhere to the inner surface of the toilet 110. Industrial availability

As described above, according to the present disclosure, it is possible to provide a sanitary washing device, which can form a foam film on the inner surface from the front to the back of the toilet to inhibit the adhesion of dirt, and can generate stable washing foam, and can prevent The unnecessary use of lotion can reduce the labor of lotion supply.
