Description

1231201 发明 Description of the invention: [Polishing bright moon t genus l butterfly shellfish ^^] Field of the invention The present invention relates to a washing machine for washing dishes by spraying washing water on the dishes. L Prior Art 3 Background of the Invention The structure of a conventional general dishwasher is shown in Fig. 40. The constitution will be described below. 10 As shown in the figure, a washing tank 2 is provided inside the main body 1 of the dishwasher, and cold water or hot water is supplied into the washing tank 2 through a water inlet valve 3. The bottom of the washing tank 2 is provided with a drainage hole 4 which is connected to a washing pump 5 driven by a motor, and the washing water is circulated inside the washing tank 2 by the action of the washing pump 5. The drain hole 4 also includes a leftover filter 6 for collecting leftovers. 15 That is, the washing water supplied into the washing tank 2 passes through the leftover filter screen 6 and is sucked in by the washing pump 5 and then supplied by the washing pump 5 to a washing device (washing nozzle) 7 provided at the bottom of the washing tank 2. The washing water sprayed from the washing nozzle 7 is circulated by washing the dishes before returning to the drain hole 4. At this time, leftovers and the like that fall off from the object to be cleaned (dishware) 9 flow into the leftover 20 strainer and net 6 together with the washing water. 6 capture it. In addition, a heater 8 for heating the washing water is provided between the cleaning nozzle 7 and the bottom of the cleaning tank 2. A tableware basket 10 is provided above the cleaning nozzle 7, and the function of the tableware is to make the tableware 9 neat. Arranged in it, make washing water; 1231201 to effectively spray on the tableware 9, improve the cleaning efficiency. In addition, the drain pump 11 discharges wash water to the outside of the machine through a drain hose 12. However, in the conventional dishwashing machine, for the objects to be cleaned, such as tableware of various shapes, which are installed in the dishwasher basket 10 and used in general households, etc., the washing water is only sprayed from below. It is difficult to wash all the dishes 9 in 10 sufficiently. In addition, if it is not sprayed from above the washing tank, there are problems that bowl bottoms such as tea cups and soup bowls with table bottoms may easily accumulate fine leftovers, or the overall flushing performance may be insufficient. In order to solve the above problem, a solution of spraying washing water from a plurality of directions with a plurality of cleaning nozzles may be adopted. However, to perform a large number of sprays at the same time, of course, the amount of water stored in the cleaning tank must also be large. In this way, the temperature rise time of the washing water becomes longer due to the increase of the water inlet amount. As a result, the working time will be prolonged, the amount of power consumed will also increase, and the amount of water consumption will increase, and a large-scale washing pump will be required. Therefore, there are many problems such as increased cost, increased noise caused by spraying a large amount of washing water at the same time, and increased vibration. In addition, in order to solve the above problems, a solution of using multiple cleaning pumps can also be considered. However, in this way, a cleaning pump needs to be set for each cleaning nozzle, and the volume of the cleaning mechanism in the entire dishwashing and drying machine will increase. This causes a problem that the volume necessary for installing the dishwasher 20 cannot be sufficiently ensured, or the main body of the dishwasher becomes unnecessarily large. In response to this, a proposal has been made to use a switching device that selectively switches the washing device to be supplied with washing water, and to perform a highly efficient washing method from multiple directions with a small amount of water. Specifically, the 3-way valve is used for switching, or the 1231201 valve body is driven by a motor. In addition, it is also possible to switch the motor by intermittently operating the cleaning pump without using an electric drive device such as a motor. The structure of switching the valve body by a motor is shown in Japanese Patent Laid-Open Publication No. 2001-218721. As shown in FIG. 41, the cylindrical valve housing 13 is provided with a cylindrical valve body 14 having a slightly smaller diameter. The cylindrical portion of the valve body 14 is provided with an opening 15. A plurality of outflow ports 16 are provided in the cylindrical portion, and these outflow ports 16 are in communication with each of the plurality of cleaning devices. In addition, a drive motor 17 for rotating the valve body 14 is provided to constitute a water separation device 19. When the cleaning pump 5 is in operation, by rotating the valve body 14, the cleaning device 7 which sprays the washing water 10 can be sequentially switched. However, in the above-mentioned structure, the slight gap between the valve housing 13 and the valve body 14 is approximately constant. When the washing water with foreign matters such as leftovers and toothpicks is circulated, the foreign matters are caught in the opening 15 and the outlet 16 After a while, the valve body 14 will be stuck and cannot be rotated, and the water separation device 19 will not work, which will cause a problem that the specified cleaning performance cannot be achieved. In addition, the valve housing 13 and the valve body 14 may be damaged. [Summary of the Invention] SUMMARY OF THE INVENTION The present invention aims to solve the problems in the prior art mentioned above, and its 120th object is to reliably perform the valve body even when foreign matters such as leftovers and toothpicks are mixed in the washing water. Switching of washing water. In addition, a second object of the present invention is to provide a water separation device capable of preventing foreign matter from being clogged, having less water leakage, and having high branching efficiency. In order to achieve the above object, in the dishwasher of the present invention, a washing device that supplies washing water from a washing pump is switched by a water separation device 1231201, and the water separating device is fed by washing water that is pressurized by the washing pump. The inflow port, a valve housing having a plurality of outflow ports respectively communicating with the plurality of cleaning devices, and a valve body that can be moved in the valve housing are formed. The inflow port of the washing water 5 is switched as the valve body rotates. The valve body can be removed from the outlet. In this way, even if foreign matter flows into the water separation device and is caught between the valve body and the valve body, the valve body's turning operation can be continued by removing the valve body from the outflow port. The invention described in the technical solution 1 of the present invention is a tableware washing machine 10, comprising: a washing tank containing the object to be washed; a washing pump for pressurizing washing water; and a washing machine for spraying washing water into the washing tank. A plurality of washing devices at a jet port; and a water separating device for switching a washing device that supplies washing water from the washing pump, the water separating device includes a stream having a flow of washing water that is pressurized by the washing pump. An inlet, a valve housing having a plurality of outlets communicating with each of the plurality of the cleaning devices, and a valve body provided to be movable within the valve body, and the rotation action of the valve body causes an outlet for supplying washing water The switching is performed, and the valve body can be moved away from the surface provided with the outflow port. In this way, the amount of water input will not be increased, and any object to be cleaned can be sprayed with washing water from multiple directions, and the cleaning performance can be improved. In addition, because cleaning can be completed in a shorter time, efficient cleaning can be achieved. In addition, because the amount of water inflow and the number of flushes are reduced, water and energy can be saved. In addition, there is no need to select the location and method of the objects to be cleaned in the cutlery basket, and a dish washing machine with better placement can be realized. In addition, since the valve body can be removed from the surface provided with the outflow port, 1231201 washing water flowing with foreign matter such as leftovers and toothpicks circulates. Even if the foreign matter gets caught between the outflow port and the valve body, the reading body can be removed from the body. When the outlet is removed, the valve body can continue to rotate. Therefore, the wide body will not be jammed when foreign objects get stuck, and it will not cause the phenomenon of being unable to rotate, damage to the casing and the valve body. In the state of foreign matter jamming, all washing devices will be supplied with washing water, but the washing water supplied at this time is insufficient. When turning to the next outflow, foreign matter recording will be normal again. Switching to the ground 'can efficiently clean the object to be cleaned, and provides a water distribution device that can remove 10 objects even when foreign objects are caught in the gap between the valve housing and the valve body. ^ 15 The invention described in the technical solution 2 is the correction described in the technical solution 1 described above, and the cleaning towel W is removed from the surface where the nuclear outlet is set. In this way, when cleaning is performed, it is difficult to prevent foreign objects such as toothpicks from being stuck between the two valve housings. 'The foreign object can be taken out when one of the outflow ports is turned.' Again, the washing is performed normally again. The cleaning material is clean. It is to be said that the invention provided in the above-mentioned technical solution ㈣ provides a kind of water separation and regeneration technical solution 3 which can be removed even if it is stuck between the valve housing and the valve. In the above description, M may be inclined from the rotation direction of the valve body. In this part, there is a foreign matter stuck in a part of the gap between the leaf valve bodies, and when a tilting force acts on the _ under the roof force phase of the washing service 7, the valve body can be prevented from acting like a skid-like card. In the case that the face cannot be switched, the technology described in Case 4 is the invention described in Case 4 in which the body is removed from the outlet when the cleaning pump is stopped in the Mao Yue described in the above technical solution 1. In this way, the outflow port and, even if the foreign matter is stuck in, and the foreign matter is removed / removed during the operation of the cleaning pump, since the gap will definitely expand when the cleaning pump is stopped, it can be reliably locked in. Remove the foreign objects. In addition, even if the foreign matter has not fallen off in this state, the water flow generated at the start of the cleaning of the pump guard will flush the foreign matter to the outflow_ side and will not continue to get stuck in the gap. 10 15 Invention technology, the invention described in item 5 is described in the above technical solution 4. There is a device for applying elasticity to the valve body in a direction away from the outflow port = elastic force & adding device. In this way, when there is a foreign matter stuck in between the valve housing and the valve body, the: out = stopped state can prevent the valve body from being able to escape from the outflow port: No matter which direction the intermediate body is set, it can be removed from / There is an advantage that there is no need to choose the setting direction of the water separation device. The invention described in claim 6 is that the earth π washing pump described in claim 1 is temporarily stopped during the washing and rinsing steps. Although the foreign matter in the card mouth and the valve body can be removed when the cleaning pump is stopped, it can only be achieved at the end of the cleaning and flushing steps, and the poor cleaning performance of this step will be reduced. Therefore, by temporarily stopping the washing process in the middle of each cycle, it is possible to switch the time of the extraordinary king in a short period of time to suppress the decline in cleaning performance to a minimum. The invention described in claim 7 is described in the above technical aspect; Pt 'is provided with a leftover gap that captures leftovers when washing water passes through, and the distance from the outlet is set to be greater than As mentioned above, since there is a gap between the outflow port and _ which is larger than the size of the foreign matter that may flow into the water device, all the possible foreign matter may be removed, so It is possible to provide a highly reliable water separation device. The invention described in the eighth aspect is the invention described in the above-mentioned aspect. The valve body is rotated to switch the outflow port of the washing water supply, and at the same time, the outflow port and the valve body are switched. The opposite surfaces are inclined with respect to the direction of the rotation axis of the valve body. In this way, if the valve body is moved in the direction of the axis of rotation of the valve body, the distance between the outlet surface and the valve body will be increased. In the gap between the bodies, the foreign body 10 can be removed from the gap when the valve body is removed. Therefore, the valve body cannot be moved after a foreign object is caught in the gap, and the valve body can be reliably switched. The invention described in claim 9 is described in the above claim 8. In the invention, 'the leftover strainer, which is capable of trapping leftovers when the washing water passes through, is provided between the valve housing and the valve body. The minimum gap is set to be larger than the gap of the leftover screen 15. In this way, since there is a gap between the outflow port and the valve body that is larger than the size of the foreign matter that may flow into the water separation device, it is possible to prevent the foreign body from being caught in the gap and the valve body cannot be switched. The invention described in claim 10 is the invention described in claim 8 in which the outflow port is provided to protrude into the valve body. In this way, the contact area between the outflow port 20 and the valve body will be minimized, foreign matter will not easily get caught between the outflow port and the valve body, and the number of poor switching can be reduced. The invention described in claim 11 is the invention described in claim 8 in which the shape of the outflow port is a fan shape. In this way, the shape of the multiple outflow ports is approximately circular, and the shape of the valve body can be minimized. A sufficient gap can be provided between the valve housing 11 1231201 and the valve body, which can prevent foreign matter from getting in, and the water separation device can also Achieve miniaturization. In addition, since the outer shape of the valve body is approximately circular, it is difficult for foreign matter to be caught between the valve housing and the valve body. In addition, the movement resistance of the valve body can be reduced, the movement of the valve body becomes smooth, and it can be completed in a short period of time. The stop time of the cleaning pump can be shortened, and efficient cleaning can be performed in a shorter time. The invention described in the twelfth aspect is the invention described in the eighth aspect, wherein the valve body has an opening portion through which the washing water passes through the valve body, and the opening portion is in accordance with the external shape of the valve body. Interlocking cut shapes. 10 Since the opening portion is not the shape of a hole but a cut shape, even if a foreign object tends to be caught between the valve body and the opening portion, the probability of being caught can be reduced because there is a place where the foreign object can be avoided. The invention described in the thirteenth aspect is the invention described in the first aspect, in which the outflow port with the washing water supply is switched in accordance with the rotation of the valve body, and the valve body is The pressure of the washing water after pressing is compacted on the outflow port. In this way, the sealing of the valve body can be improved, washing water leakage to places other than the outflow port of the washing water supply can be greatly suppressed, more washing water can be ejected from the washing device, and the washing performance can be further improved. 20 The invention described in claim 14 is the invention described in claim 13 above. The valve body is separated from the outflow port when the cleaning fruit is stopped, and is in contact with the outflow port when the cleaning pump is in operation, thereby washing water Supply to a predetermined outlet. In this way, when the cleaning pump is stopped, the valve body must be separated from the outflow port, which can remove the trapped foreign matter, thereby preventing the washing water from being sprayed onto the entire cleaning tank due to poor switching 12 1231201, resulting in poor cleaning. And so on. The invention described in the fifteenth aspect is the invention described in the thirteenth aspect, in which the valve body is provided with respect to the outflow port so as to be able to move forward and backward freely, and moves substantially linearly before contacting the outflow port. Sampling, the valve body moving under the action of pressurized washing water does not rotate when it is against the outlet, and the valve body does not move when it is against the outlet. The two are in contact with each other. There is almost no wear on the surface, and the change in diameter over time during use can be reduced, which can prevent switching performance and 10 component strength from deteriorating from the original state due to wear. The invention described in claim 16 is the invention described in claim 13 above, in which the rotation angle when the valve body rotates when the cleaning pump is stopped is larger than the rotation angle when the valve body is operated by the cleaning pump. . In this way, the distance that the valve body is rotated while being pressurized will be reduced, and the wear of the engaging parts that cause the valve body to rotate will be reduced. In addition, the time from the start of the cleaning pump to the valve body abutting the outlet will be shortened, and the probability of foreign objects being caught can be reduced. The invention described in claim 17 is the invention described in claim 13 above, in which the rotation angle of the valve body when the cleaning pump is stopped is 20 when the cleaning pump is stopped. small. In this way, the rotation angle when the cleaning pump is stopped will be smaller, the moving time of the valve body will be shortened, the time during which the cleaning pump is stopped can be shortened, and the cleaning efficiency can be improved. The invention described in claim 18 is the invention of 123l20l described in claim 13, wherein the rotation angle of the valve body when the cleaning pump is stopped and the rotation angle of the valve body when the cleaning operation is stopped are equal to those of the valve body. The rotation angle during operation is approximately the same. 7 The inclination degree of the spraying member t that restricts the rotation angle during ascent and descent will be the same on the ascending and descending sides, and reliable operation can be achieved without malfunction in both directions. The invention described in the 10th, 20th, and 25th aspect is the invention described in the above technical aspect, which is provided with a coupling member that makes the valve body move substantially linearly and rotationally with the intermittent operation of the cleaning system. The center of the rotation of the salivation member with respect to the outlet 2: 2: -side of the body. In this way, it is possible to reduce the probability that the rotating parts of the same day will stabilize the rotation of the valve body as the valve body turns. "To reduce the wear of low-fitting parts, reduce the occurrence of poor switching, and reduce the movement of the valve body to make the valve body approximately straight line = Γ; Γ combining parts, the connecting parts are arranged between adjacent two. It is read that there are mouth-fitting parts on the inside and outside of the outflow port. When the area is the same, the size (outer diameter) of the body can be minimized, and the water separation device can be miniaturized. J (外 位) 文 仔 取 The invention described in the technical scheme 21 = _: VALVE_—The contacting side is composed of an elastomer, and the valve body and can, ㈣. In addition, when contacting, it will move approximately linearly. The invention described in the technical scheme 22 is better. In the invention described in the technical scheme 1, the 1214201201, the shaft provided on one of the valve body and the valve body and the hole provided on the other side Fit in a freely rotating manner. In this way, when the relative movement between the valve body and the valve housing, the shaft and the hole located near the center are close to or in contact with each other. Compared with the case where the relative movement is performed on the outer circumference of the valve body, the areas facing each other will At the minimum, the probability of foreign objects being trapped will also become smaller. In addition, even when foreign matter is caught in the gap, the force required to rotate against its resistance is minimized, and the valve body can be moved by the fluctuation of the water flow in the valve housing. Thus, even when the force to rotate the valve body is small, there is almost no possibility that the valve body cannot be rotated by foreign matter. Therefore, it is possible to prevent the occurrence of a situation in which the water separation device cannot be switched by a foreign object and cleaning cannot be performed in the entire cleaning tank ', and a highly reliable cleaning device can be provided. The invention described in the next 15th technical solution 23 is the elaboration in the second technical solution of the second technical solution. In the elaboration of the second technical solution, there are close-fitting parts with holes on the holes. Space section. In this way, only a plurality of close parts make contact between the sister holes, and it is more difficult for foreign objects to be trapped. Once the trapped objects are moved, the valve body can be easily removed, so that It can avoid the situation that the valve is switched due to the foreign body jamming. The invention described in the Japan-Japan case No. 24 is the hair described in the technical scheme 22. The outer circumference of the shaft is provided with a convex-shaped portion extending in the mysterious direction to constitute a proximity member, and at the same time outside the shaft and the hole The upper part is respectively provided with a rotating coupling member. During the operation of the cleaning pump, the tritium water bisects with the internal flow and is adjacent to the coupling member provided on the hole-side. between. Read that it is possible to jam foreign material in the shaft and hole clearance material. The probability of foreign object jamming during operation can be reduced in the gap between the shaft of the 1231201 shaft and the resonating part, which can further improve the reliability of the device against foreign objects. The invention described in claim 25 is the invention described in claim 24, in which a recessed portion is provided between adjacent tops of the engaging members provided on the side of the hole, and the convex portion and the recessed portion are opposed to each other. quasi. In this way, the possibility of foreign objects getting caught in the gap between the shaft and the engaging member can be completely eliminated. In the invention described in claim 26, in the invention described in claim 22, when the flow of wash water is stopped or reduced, the valve body starts to move and performs a turning operation. In this way, when a foreign object is caught in the approaching part, if the valve body starts to rotate while starting to move, the foreign matter will move into the wide space between the approaching part and the approaching part, so that the foreign matter can be reliably removed . In the invention described in claim 27, in the invention described in claim 22, the center of the inlet of the washing water flowing into the valve housing is shifted from the center of rotation of the valve body toward the outer circumferential side. In this way, a vortex swirling in the valve housing will be generated in the valve housing, and foreign materials such as leftovers that account for most of the foreign matter and have a large specific water ratio will move to the outside of the valve housing under the action of the vortex. Therefore, the foreign object tends to be far away from the shaft and the hole located near the center of the valve housing, and the probability of the foreign object getting caught in the gap 20 between the shaft and the hole can be reduced. In the invention described in claim 28, in the invention described in claim 1, the valve body is provided along the inner surface of the valve housing to be freely rotatable, and the inner surface of the valve housing and the valve body are opposed to each other. A plurality of access portions are provided on the outer surface, and a space larger than the near portion of the connection portion 16 1231201 is formed between adjacent access portions. In this way, the relative movement between the valve body and the valve housing is substantially only the proximity part, and its area is smaller than that when the relative movement is performed on the entire circumference, and the probability of foreign matter getting in can be reduced. This can prevent the situation that the water separation device cannot be switched by foreign objects, and the cleaning in all 5 cleaning tanks cannot be performed, and a highly reliable cleaning device can be provided. In the invention described in claim 29, in the invention described in claim 28, the inner surface of the valve housing and the outer surface of the valve body are substantially circular, and either one of the inner surface of the valve housing and the outer surface of the valve body is provided with a plurality of 10 convex portions, constituting an approximate portion. In this way, the clearance of the round part other than the convex part is set to prevent foreign matter from being caught, and the valve body and the valve housing only move relative to each other through a plurality of convex parts, and the areas facing each other will become smaller, even if foreign matter is caught in In the gap, once the stuck foreign matter is easily removed due to the valve body slightly moving, the situation of stuck foreign matter is less likely to occur, and the situation that the water separation device 15 cannot be switched can be prevented. The invention described in claim 30 is the invention described in claim 1 above, in which the valve body is rotated by intermittent operation of the cleaning pump. This eliminates the need for a dedicated electric drive device such as a motor, thereby reducing costs and miniaturizing the device. 20 The invention described in claim 31 is the invention described in claim 1 above, in which the valve body is rotated by the electric drive source. In this way, the valve body can be reliably rotated, and the washing device provided with washing water can be switched. The invention described in claim 32 is the invention described in claim 17 I23120i described in claim 31 above, in which the electric drive source is operated while the washing pump is stopped. In this way, the valve body can be rotated in a state where the pressure of the washing water does not act, thereby suppressing abrasion on the contact portion between the valve body and the outflow port, and improving the life and reliability of the water separation device. 5 [Implementing the cold type] Detailed description of the preferred embodiment The embodiment of the present invention will be described below with reference to the drawings.

The valve body 41 can also be moved in the vertical direction in addition to the rotation action, and can move forward and backward relative to the outflow port 39. When the washing pump 26 is operating, the valve body 41 rises under the pressure of the washing water flowing from the inflow port 38 and approaches the outflow port 39. The drive motor 54 rotates the valve body 41, and a strip washing water is supplied to the outflow port 39 corresponding to the position 10 of the opening portion 42, and a strip washing water is sprayed out to the cleaning device 27 communicating with the outflow port 39. By rotating the valve body 41, the outflow port 39 'to which the washing water is supplied can be sequentially switched, and the washing device 27 spraying the washing water can be switched in the order of 27a, 27b, 27c, and 27d. At this time, the driving method of the driving motor 54 includes a continuous 15 driving method, an intermittent driving method of stopping the opening portion 42 at the position of the outflow port 39, and the like, but it is not limited to these two methods. In addition, "in the case of the former method", components such as sensors that do not need to detect the position of the valve body 41 are relatively simple. In the case of the latter method, although a position sensor or the like is required, the switching efficiency is high. 2 O The position and spray time of the cleaning device 27 can be selectively set according to the situation. Under the function of the above device, the washing water is not supplied to the four washing devices 27 at the same time, but the washing water is sequentially supplied, so the amount of water supply is not increased. For any object 23, the washing water can be sprayed from multiple directions. . Therefore, 21 1231201 can clean the dirt attached to the object M to be cleaned in a short percentage of time, thereby achieving highly efficient cleaning. Since the detergent and leftovers adhering to the object 23 to be cleaned, such as tableware, can be washed out in a short time, the number of washings can be reduced. For example, you can reduce the original 4 times to 3 times. The amount of water supplied every time is not increased, and because: the number of less is reduced, the heating device 30 can be shortened to heat the washing water, which can save energy and water. .

In addition, since 增加 increases the number of washing sprays 10 f27 without increasing the amount of water, it is possible to use a washing method in which washing water is sprayed from multiple directions relative to the object M to be cleaned. In this way, the user can place the object to be cleaned 23 in the tableware t24 with the consideration of the placement, vertical, horizontal and other methods', and can freely place the tableware j with better placement. Moreover, even for dishes that cannot be sufficiently cleaned by single-direction spray washing with square-shaped small bowls, deeper small bowls, and square 15 plates, etc., the seam is sufficient to exert the cleaning performance. ,

In addition, the spray time of the cleaning device 27 in one place can be switched from a few seconds to the right of the branch office, so that efficient cleaning can be performed. However, during the cleaning or flushing process, it is set to spray all the cleaning devices (20 to 27). Therefore, the above-mentioned spraying time can be set. Since the intermediate body 41 疋 is driven by the driving motor (electric drive source) 54, the reading body 41 is rotated, so that the washing unit 27 to which the washing water is supplied can be reliably switched. 22 1231201 In addition, as shown in Fig. 5, the valve body 41 is still moved and is separated from the surface A provided with the outflow port 39. That is, the valve body 41 can be moved downward, and even when the cleaning pump 26 is operating, such a movement can be performed. Since leftovers and toothpick 4 foreign matter 49 will be mixed in the washing water and circulated together, as shown in FIG. 6, when the gap between the opening 42 and the outlet 39 is getting smaller and smaller, the foreign matter 49 sometimes It just happens to be caught in it. If the valve body 41 is not separated from the outflow port 39, some kinds of foreign matter 49 will cause the valve body 41 to become stuck, and the switching cannot be performed. When the driving force of the driving motor 54 is strong, the valve body 41 and the outflow port 39 may be damaged. Therefore, in the present invention, the valve body 41 can be separated from the surface A on which the outflow port 39 is provided, and can move as shown in FIG. Leave the rotary drive unaffected. When foreign materials are stuck in, all the cleaning devices 27 have washing supplies, but the _ washing water i and the supply 疋 are not sufficient. When transferred to the next outlet position, U foreign objects 49 are flushed. So that the washing water can be switched normally again and the object to be cleaned can be washed efficiently. In addition, the foreign object 49 can be from a variety of things, in addition to food, it can also be fish bones, toothpicks, rubber bands, plastic paper or cutlery, and so on. In particular, slender objects such as flounder and cherry stems, regardless of their length, may pass through the leftover strainer, so it is necessary to take measures against such foreign objects. The stuck foreign objects 49 mentioned above can generally be removed after passing through one or several outflow ports 39, but there are also cases where thin foreign matter with long lengths is not easy to remove. For this reason, when the cleaning pump 26 is temporarily stopped at the Bura TJL halfway, the valve body 41 under the action of its own weight of 23 1231201 at the time of stopping is the same as the outflow port 39, and no foreign matter will be removed, and the stuck foreign matter 49 will be removed. This bukka human shooting caused the valve purchase to be unable to rotate, so it was possible to reliably switch „41. b The 5 10 rotation, say :::: pump! 6 will stop at least at the end of the washing and rinsing steps, 5❿ The possibility of degradation of cleaning performance due to poor switching: Existence: but from the next use, there will be no use. In addition, the cleaning fruit 26 is stopped in the middle of the cleaning and rinsing steps. Success: If you are a human, the number of switching will be minimized, and the decrease in cleaning performance can be suppressed to a minimum. As shown in Figure 7, the direction of the valve body 41 relative to its linear movement = downward direction ™ oblique. From When looking at the transmission part of the reader 41 and the motor shaft 55 with the cross section of the motor as the upper part, you can see that there are spaces between the motor shaft 55 and the valve body 41 as in the past, in all directions Both can be tilted. In this way, the valve body 41 can move smoothly even if a foreign object 49 is caught. In addition, the end face of the contact portion between the outflow port 39 and the opening can be processed into a corner, a fillet, etc. , So that the separation operation of Dragon 41 can be made more smooth In addition, even if a foreign matter 2049 is caught in a part of the gap between the outflow port 39 and the valve body 41, it is possible to apply an inclined force to the valve body 41 due to the pressure of washing water or the like. It prevents the valve body 41 from being stuck in the valve installation 40 and the like like a pry bar, so that the valve body 41 cannot be switched. In this way, the inclination angle of the valve body 41 and the valve housing 40 without damage can be set to The angle of inclination is larger than the angle of inclination of the different size 24 1231201 object 49 with the same size as the gap of the leftover filter 29. In addition, the joint between the valve body 41 and the motor shaft 55 can be a universal joint, of course In a similar manner, the same effect can be achieved by X. In addition, when foreign matter 49 is stuck between the valve housing 40 and the valve body 41 at the moment when the cleaning pump 26 starts to operate, all the cleaning devices 27 will be supplied First: the supply of water and washing water may be inadequate, but when the cleaning pump 26 is temporarily stopped, the distance between the outlet 39 and the valve body 41 will become larger, foreign objects 49 will be removed, and the cleaning pump 26 will start again Cut without problems at work The object to be cleaned 23 can be cleaned efficiently. In addition, as shown in FIG. 9, when the cleaning pump 26 is stopped, an elastic force applying device 50 may be provided to separate the intermediary body 41 from the outflow port 39. The intermediate body 41 exerts an elastic force in a direction separating from the outlet 39. In this state, foreign matter 49 is caught between the valve housing and the valve body 41, and the cleaning pump 26 is stopped. When the separation occurs, the foreign matter 49 can be reliably removed in the stopped state. After the above structure is adopted, 'the valve body 41 can be separated from the outflow port 39 regardless of the direction in which the valve body 41 is installed, so that the water separation device 37 is provided. The advantage can be set at any angle (direction). Besides the elastic force applying device 50, an elastic body such as a plate spring or rubber can be used in addition to the circle shown in the figure. In the working state of the cleaning pump 26, the pressure in the valve housing 40 is described as "the body 41 is pressurized upward to the side of the outflow port 39, and the degree of close contact between the valve body 41 and the cover is obtained. Enhancement, the leakage of washing water can be greatly reduced, so that more washing water can be removed from the washing device 27, and the washing performance can be further improved. If the valve body 41 and the flow 25 1231201 outlet 39 can be deformed under the action of water, the above sealing performance can be further improved. In addition, during the operation of the cleaning pump 26, the inside of the valve housing 40 is usually pressurized to about 20 to 40 kPa. Although the force acting on the valve body 41 is not 5 because of its size, the passage # is approximately 20 to 100N. Left and right, so that it is firmly pressed on the outflow port 39. On the other hand, in a state where the valve body 41 is pressurized by the washing water, the valve body 41 will cause great friction when it rotates, and the valve body and the outflow port M may be worn. By operating the drive motor 54 Stopping the cleaning pump 26 can solve this problem. When the cleaning pump 26 is stopped, the valve body 41 is driven to rotate until it reaches the next prescribed position, and then the driving motor 54 is stopped to make the cleaning pump 26 work again. In this way, the valve The body 41 only abuts on the outflow port 39. 'No sliding occurs, so there is almost no abrasion. In this way, the life and reliability of the water separation device 37 can be improved. In addition, 15%, even if the pump is cleaned and the drive motor It is not necessary to completely stop the cleaning pump 26 if the 54 works at the same time as part of the time. “Although it is hoped that the outlet 39 and the valve body 41 can be closely fitted,” even if the size of the component When there is a slight gap due to reasons such as accuracy, or if the slight gap is set to less than 1mm, although there is a slight leakage in the sheath 39 to the other outlet port 39, the water separation device 37 can be overcharged. In addition, the distance between the valve body 41 and the outlet 39 is greater than the gap in the leftover piping net π. In this way, a filter 29 may be formed between the outlet 39 and the valve body 41 than possible. The size of the foreign matter 49 flowing into the water separation device 37 is larger than the gap of 26 1231201. Therefore, the foreign matter 49 stuck in the cleaning pump 26 can be removed during the stoppage of the cleaning pump 26, thereby providing a water separation device that can always maintain high reliability. 37.

In addition, the gap in the above "leftover filter screen 29 gap" refers to the size corresponding to the diameter of the round hole, the length of the side of the mesh, etc. Strictly speaking, it is possible to wear as shown in Figure 5-10. The minimum size B of the foreign matter 49 of the excess food filter 29 is larger than the minimum size B. In addition, the residual food filter 29 may include a fixed filter 51 that is fixed to the drain port 28 and a removable filter that can be removed for cleaning. These two filters are net 52. As long as it is set to the size of the smaller gap (usually the removable filter 52), there is usually no problem during work. However, 10 is' due to the existence of removable The filter 52 may be incorrectly installed or forgot to be installed, and it is more reliable to set the distance far larger than the gap of the fixed filter 51. In addition, the minimum gap between the valve housing 40 and the valve body 41 is set to be greater than the leftovers. The gap between the screen 29. The gap between the valve housing 40 and the valve body 41 refers to the straight distance from the outer circumference and the end face of the valve body 41 to the valve housing 40. In addition, the meaning of the leftover filter 15 is greater than the gap of the screen 29 Same as above. In this way, since the outlet 39 and the valve body 41 Since there is a gap larger than the size of the foreign matter 49 that may flow into the water separation device 37, it is possible to prevent the foreign matter 49 from being caught in these gaps and preventing the valve body 41 from being switched. In addition, which washing device 27 is supplied to If a nuclear testing device (not shown in the figure) is used to perform a 20 nuclear test on the washing water, the spray time of each cleaning device 27 can be changed for more efficient cleaning. For example, in order to improve It is effective to set the cleaning time of the rice bowl from the cleaning device 2 to a longer spraying time than other devices. The bismuth measuring device may include a device that detects the rotation position of the valve body 41, and a 27 2731201 measuring cleaning path. There are many types of devices such as the pressure in 43 or the presence or absence of running water. In addition, it is not necessary to install sensors in 4 places. As long as the sensors are installed in 1 place, it is combined with the operation / stop and transfer of the cleaning pump 26. If it is, you can know from which position the washing water is sprayed out. 5 In addition, it is not necessary to use all the cleaning devices when the amount of the objects to be cleaned 23 is small. When spraying washing water, the spray time of unnecessary cleaning device 27 can be set to an extremely short time of less than 1 second, so that they hardly spray, and only the necessary cleaning device 27 sprays; so, The cleaning can be performed with higher efficiency in order to shorten the working time. In addition, the final spraying in the washing process is performed by 10 by a washing device 27c provided above the cutlery basket 24, which can reduce the adherence to the object to be cleaned as much as possible. Fine water droplets to further improve the cleaning performance. In addition, in this embodiment, there are cleaning devices 27 provided in four places, and all of them are rotatable rotating nozzles. However, it is not limited to 4 15 places, and can also be based on tableware. The number of dishes in the basket 24 is set to set the number of washing devices 27. Although the effect can be exerted at two or more places, considering that the fact that all the dishes can be sprayed in two directions or more is very important to improve the cleaning performance, it is best to set it at four or more places. Conversely, when the number of branches is too large, the total amount of water sprayed by 20 from one cleaning device 27 will decrease, and the cleaning effect will be poor. Therefore, it is best to set it at 10 or less, especially 6 or less. In addition, the use of rotating nozzles in the cleaning device can indeed improve the cleaning performance. However, there is also a case where the space occupied by the cleaning device 27 increases and the outer casing of the main body has the same size. 28 1231201 Reduced problems. Therefore, as shown in FIG. 11, the fixed nozzles 27c and 27d which do not rotate for the cleaning nozzles provided on the back and above can effectively solve the above problems. The arrangement of rotating nozzles and fixed nozzles and the number of nozzles are not restrictive. 5 In addition, the cleaning device 27 can be optimally differentiated according to the shape of the main body 20 of the dishwasher, the dishware, and the like, so that the cleaning performance can be further improved. For example, as shown in FIG. 12, the cleaning device 27 can be arranged at 3 places such as 27 ^ 2713,276, or as shown in FIG. 13, the tableware basket 24 is divided into the lower S and the middle part of the upper and lower baskets 24 are provided. Turn the nozzles 10 27c, 27d and so on. In addition, 'Although in the above description, there is only one cleaning rack 27 for spraying at a certain time among the plurality of cleaning devices 27, it is also possible to pass two or more openings 42 on the valve body 41, It is also possible to switch the positions of a plurality of cleaning devices 27 by spraying them simultaneously. 15 In addition, if one of the plurality of outflow ports 39 is connected to a discharge passage for discharging washing water to the outside of the machine, drainage can be performed without the drainage pump 32. As a result, it is not necessary to provide the drain pump 32, which can reduce the cost and reduce the size of the device. In addition, when the cleaning device 27 is sequentially switched during the cleaning process, the washing water 20 will flow into the above-mentioned outlet%, so that the water will be drained as long as the cleaning% is continuously operated during the cleaning process. For this reason, it is possible to detect which outflow port 39 the washing water is being supplied to, and do not supply the washing water to the outflow port 39 for the water during the time other than the drainage, so as to prevent the outside of the machine from being discharged outside the drainage. drain. In addition, by providing an on-off valve in the drainage passage, 29 1231201 can reliably prevent the washing water from being discharged to the outside of the machine. In addition, the present invention is an invention related to a switching method of washing water, and there are no special requirements regarding the shape and size of the main body 20 of the dishwasher, the opening and closing method of the door 21, the arrangement of objects to be cleaned such as tableware, and the arrangement of each component. /limited. In addition, the dishwasher with a drying function is shown in this embodiment, and the same effect can be achieved with a dishwasher without a drying function. (Embodiment 2) The structure of the water separation device 37 in this embodiment is as shown in Figs. 14 and 15, and 10 is the same as in Embodiment 1 by a reading case 40 provided with an inlet 38 and four outlets 39 and The movable valve body 41 is configured. The valve body 41 is provided with an opening 42 through which washing water passes. However, the driving motor μ for driving the valve body 41 is omitted. As a substitute part, a set of upper meshing parts for the valve body 41 to rotate the valve body 41 by a predetermined angle are provided on the valve casing 40 side and the valve body 41 side, and the valve body 41 is caused to lower the valve body 41 when the valve body 41 is lowered. A group of lower spraying parts that rotate at a predetermined angle 45 ° As shown in Figure 14, the valve housing 40 is slightly cylindrical, and its axis direction is overhauled and arranged in the vertical direction for pressure washing by the cleaning pump 26 An inflow port 38 into which water flows in is provided on the lower end of the valve housing 40, and an outflow port 39 is provided on the upper surface of the valve housing 40. The valve body 41 has a slightly flat shape, and the surface A opposite to the valve body 41 at the outflow port 39 also has a flat shape. When the washing pump 26 is operating, under the action of the water flow (pressure) of the washing water flowing from the inlet 38, the valve body 41 rises in a roughly linear motion with a rotating motion along the slope on the upper engaging member 44 as shown in the first paragraph. As shown in FIG. 15, the outlet 39 is fixed at a predetermined position at 30 1231201, and the washing water is sprayed from the cleaning device 27 connected to the outlet%. The upper spraying member 44 (the detailed structure of the engaging member is shown in the cross-sectional view, refer to FIG. 18) is set so that when viewed from directly below the valve body 41, a washing device provided on the carcass ^ 5 The opening 42 at the position where the business water flows and the above-mentioned outflow q 39 are aligned with each other as shown in FIG. 16. Next, when the cleaning pump 26 is temporarily stopped, the pressure of "lifting the valve body upward from below is no longer effective, and the valve body 41 falls under its own weight. However, at this time, the valve body 41 is along the lower engaging member 45 The upper inclined surface rotates 10 times to fall, and finally stops at the predetermined position shown in Fig. 17. When the cleaning pump 26 operates again, the valve body 41 meshes with the next inclined surface of the upper salivation member 44 and rises while rotating. Is connected to the next outflow%, so that the next washing device 27 sprays washing water. In this way, by intermittently operating the washing pump 26, the washing device 15 27 27, 27b, 27c can be sprayed. Switching the order of 27d and 27d can achieve a high cleaning effect by the water separation device 37 as in Example 1. The circular upper engaging member 44 and the lower engaging member 45 cannot be expressed after being stretched in a plane. In terms of the relationship, as shown in FIG. 18, the valve body 4m performs a combination of a substantially linear motion and a rotational motion in the vertical direction 20 by continuously repeating the operation / stop of the cleaning pump 26. The position change is performed twice. In addition, in this embodiment, in order to sequentially switch the outflow ports 39 at four places, the stop / rework valve body 41 is rotated 90 degrees after one or two underruns, as shown in FIG. 18 'The upper meshing member 44 and the lower meshing member 45 are set to rotate about 20 degrees when the valve body is raised and about 70 degrees when it is lowered. 31 1231201 In addition, the shape of these meshing members is not limited to spiral and triangular shapes. It is only necessary to align the predetermined outflow port 39 and the opening portion 42 of the valve body 41 when the cleaning pump 26 is intermittently operated. For example, instead of forming a triangular claw portion shape, it may be formed as shown in FIG. 19 The structure in which the guide roller 47 moves 5 in the groove 46 is also possible. In addition, the position of the engaging member is not limited to the periphery of the valve body 41. In this way, the switching of the washing device 27 spraying the washing water can be performed by the washing pump The intermittent operation of 26 can be realized, and the electric drive mechanism such as the 3-way valve and the motor can be omitted, which can reduce the cost and realize the miniaturization of the water distribution device 37. In addition, in the case of motor drive, due to the rotating shaft Need to install the through-valve casing 40 'Comprehensive sealing device is required to complicate the structure. At the same time, when the seal is poor, water may leak to the outside of the product. In the structure of the present invention, there is no component for the through-valve casing 40 to work, so Worry about leakage of water to the outside. In the state when the cleaning pump 26 is operating, the valve body 41 is pushed to the outflow port 39 under the pressure of the valve housing 40 and is pushed upward. In this way, because The close contact between the valve body 41 and the sealing surface of the outflow port 39 is enhanced, and the leakage of the washing water can be reduced to a very small degree, so that more washing water can be ejected from the washing device 27, which further improves, Main, first & 20 can. If the valve body 41 or the outflow port 39 is under the action of water pressure ... If it cannot be deformed, the above-mentioned sealing performance will be further improved. In addition, in this embodiment, the ascending action of the valve body 41 is realized by the pressure of the pressurized washing water, and the descending action is performed under the action of the valve body 41 immersed in soil, and the axis direction of the valve body 41 needs to be set In a roughly straight direction _ In the case of 32 1231201, the specific gravity of the valve body 41 needs to be above 丨, the larger the range of rise, the more reliably it can enter ^: the sundial body 41 can be used to switch the water distribution device 37 The higher the performance. It can also complete the switching operation with the lower body and rotating fat material. '41 ^ Officials are made of materials with a heavy specific gravity, such as metal or linoleum, and they are used by people and metal materials: Fang In addition, 'by using the on-flow outflow device, you can reliably make _ 41 to move. + In the case where the elastic force is 10 15 20 2, it is not necessary to set the water separation device 37 at. Up, but can be set in any direction. T = ::: r, 41 is-while being pressurized-the transfer of the spraying part 44 of the sliding part works. Therefore, by preventing the upper part from being worn down, it is possible to reduce the occurrence of the poor replacement of the upper attachment member 44 and the position of the outflow port 39, and the position of the outflow port 39 is not the same. And 'can make the probability of starting from the cleaning pump 26 can be reduced: the time from 39 to can be shortened, the foreign matter 49 card on the other hand, although wonderful = efficiency can be improved. The rotation operation is not shown in Figure 3, the cleaning pump is stopped when the valve body is in operation and the valve body 41 is completed. When the rotation angle is small, the cleaning will be shorter, and the cleaning / rotation angle will be smaller. The moving time of the valve body 41 can be extended. The main stop time can also be shortened. Efficiency can be improved. 2. Dispose the upper meshing member 44 and the lower meshing member 45, 33 1231201 so that the rotation angle when the valve body 41 completes the rotation action when the cleaning pump 26 stops and the rotation angle when the valve body 41 completes the rotation action when the cleaning pump 26 operates When the phases are approximately in phase, the inclination degree of the meshing member that determines the rotation angle during ascent and descent is as shown in FIG. 20, and the inclination degree G on the ascending side and the inclination degree Η on the descending side are both maximum values of 45 degrees. In this way, reliable operation without malfunction can be achieved in both directions. 10 In addition, as shown in Figs. 14 to 17, the upper engaging member 44 and the lower engaging member 45 may be provided on the inner side of the outflow port 39 (the opening portion 42). When rotating, the inner side has a lower peripheral speed than the outer circumference of the valve body 41, and the moving distance is also smaller. The angle of the inclined surface of the engaging member is also steeper, and the turning motion of the valve body 41 is more stable. At the same time, the abrasion of the upper meshing member 44 and the lower meshing member 45 can also be reduced ', thereby reducing the probability of occurrence of poor switching.

15 20 Naichong, on the upper side of the engaging element, the cleaning pump 26 runs when it works 41. The valve body 41 performs a roughly shoulder-line motion before it comes into contact with the outflow port 39. That is, the protrusion part F of the upper salivation member M 'as shown in FIG. 18 moves substantially linearly upward. Therefore, "41 does not rotate and moves under the relative washing narcissus" and the outflow port 39 abuts, and the valve body 41 does not-while rotating-while weaving the oral magazine "has almost no contact surface on the branch The occurrence of wear can reduce the change of the diameter of X with the use of time, and will not cause the phenomenon of inferior switching performance and component strength compared with the initial state. It is necessary to use words to generalize and use them in general. ΡρΒ temple resin molded parts can be.

In addition, if two of the contact portions of the valve body 41 and the outlet 39 or any of 34 1231201 are formed of elastic materials such as rubber and elastic plastic, the starting and landing properties between the valve body 41 and the outlet 39 will be greatly improved. Of improvement. However, when the valve body 41 and the outflow port 39 need to slide, they cannot be used because of the high frictional resistance. As in the present embodiment, if the valve body 41 is used in a structure that moves approximately linearly before contacting the outlet port 5, the wear of the elastic material body is reduced, and a better effect can be produced. In addition, if a detection device (not shown) that detects which washing device 27 is being supplied with washing water is used, the spraying time of each washing device 27 can be changed, so that more efficient washing can be performed. For example, if you want to increase the cleaning power of 10 items that are difficult to wash, such as rice bowls, it is effective to set the spray time of the cleaning device 27a longer than other cleaning devices. There are various methods such as a device that detects the rotational position of the valve body 41, a device that detects the pressure in the cleaning passage 43, the presence or absence of flowing water, etc. In addition, it is not necessary to use sensors in four places. A sensor 'is set at j 15 and the operation / stop, rotation speed, and other information of the cleaning pump 26 are combined to know from which position the injection is being performed. In addition, when the amount of the object to be cleaned 23 is small and it is not necessary to spray washing water from all the cleaning and repairing devices 27, the spraying time of the unnecessary cleaning device 27 can be set to an extremely short time of about 1 second or less, so that There are hardly 20 sprays, and only the necessary cleaning device 27 is sprayed. This way-cleaning can be done more efficiently and the operating time can be shortened. In addition, by setting the final spray in the rinsing stage to be performed by the washing device 27c located above the tableware basket 24, it is possible to reduce the fine water droplets adhering to the laundry as much as possible and further improve the cleaning performance. 35 1231201 In addition, the surface A provided with the outflow port 39 and opposed to the valve body 41 is inclined with respect to the substantially linear movement direction (ie, vertical direction) of the valve body 41. As shown in FIG. 15, the facing surface between the outflow port% and the valve body q is a horizontal direction, which corresponds to a 90-degree inclination from the linear movement direction of the valve body 41. In this way, since the valve body 41 performs a linear motion at the time of switching, it has the effect of increasing the distance between the opposed surface a between the flow outlet 39 and the valve body 41. Even if foreign matter 49 such as leftovers and toothpicks are mixed in the washing water and circulated together, the foreign matter 49 gets caught in the gap between the valve housing 40 and the valve body 41. When the cleaning pump 26 stops and the valve body is spread out, the foreign matter 49 can still be removed from the gap. Clear it out. In this way, it is possible to avoid jamming of the foreign body 49 of φ 10, and to achieve the same function and effect as in Embodiment 1, so that the valve body 4i can be reliably switched. In addition, when foreign matter 49 is stuck between the valve housing 40 and the valve body 41 at the moment when the cleaning pump 26 shown in FIG. 21 starts to operate, all the cleaning devices 27 will be supplied with washing water, but The water supply may be insufficient and 15 feet. Once the cleaning pump 26 is stopped, the distance between the outflow port 39 and the valve body 41 will be widened, and the foreign matter 49 can be removed. The next time the cleaning pump 26 works, it can be smoothly switched, so that the cleaning object can be highly efficient. 23 Wash clean. "In addition," even if the foreign object 49 does not fall off when the cleaning pump 26 is stopped, the foreign object 49 will be flushed toward the outflow 39 side under the water flow when the cleaning pump 26 starts to work, and will not continue to be stuck in the gap. in. In addition, if the cleaning pump 26 does not remove the foreign matter 49 after being stopped / re-operated once, the foreign matter 49 can be removed by repeatedly stopping / re-working the process. In addition, if the shape of the valve body 41 is slightly inclined on the upper surface, the foreign matter 49 can be more easily removed. 36 1231201 In addition, as shown in FIG. 16, the minimum gap J between the valve housing 40 and the valve body 41 is set to be larger than the gap of the leftover filter screen 29. The gap between the valve housing 40 and the valve body 41 is a straight distance from the outer edge or the end surface of the valve body 41 to the valve housing 40. In this way, there is a gap between the outlet 39 and the valve body 41 that is larger than the size of the foreign matter 49 that may flow into the 5 water dividing device 37, so that the foreign matter 49 can be prevented from being caught in the gap, causing the valve body 41 A situation where switching is not possible occurs. In addition, although the upper valve body 41 has a flat shape, this is not a limiting rule, and even if it is made into a cone or a sphere, it can suffice against the outlet 39 under the action of water pressure. ♦ 10 As shown in FIG. 15, each of the outflow ports 39 is provided in a tubular shape and protrudes into the valve housing 40. In this way, the contact area between the outflow port 39 and the valve body 41 is only the end area of the four pipes, which is much smaller than when there is no protrusion, and it is not easy for the foreign matter 49 to be caught between the outflow port 39 and the valve body 41. Thereby reducing the number of poor handovers. However, such a structure is not limited, as long as the shape of the outflow port 39 15 and the valve body 41 is appropriate, the same effect can be achieved even if the shape is not protruding. In addition, in the above embodiment, the cleaning pump 26 continuously repeats the work and stop processes. However, when the cleaning pump 26 uses an inverter motor and the output of the pump ® can be changed, the output strength of the pump can also be used.来 开关 阀体 41。 Switching valve body 41. When the output in the "weak" state is set to an output that the valve body 41 can separate from the outlet 39 minutes and 20 minutes, the switching can be completed, and the number of pump operations and stops can be reduced. In this way, the life of the motor can be extended and the operation can be made quieter. In addition, Fig. 15 shows a structure in which a shaft 60 provided in the valve case 40 is inserted into a hole 61 provided in the valve body 41. The shaft 60 and the hole 61 are very close to 37 1231201 or they are in contact with each other, and the upper and lower sides of the intermediate body are restricted. For example, the outer body of the valve body 41, and the rotation action. When 偟 is 100mm and the diameter of the shaft portion 61 is 5mm, the relative area (circle ~ very small by 2._4, __, and __) is relatively small. The probability of the object is also much smaller. Gongshi rushed into Wu against the resistance of the foreign body and turned: up, even if the gap is stuck in the gap of about i, there is no required force (turn_like, only lion workers ',', the drive device depends on the valve housing 40 The fluctuation of the water flow can move the valve body 41. The force required to move the valve body is also reduced, and there is almost a possibility that foreign objects may jam the valve body 41 and prevent it from turning. This can prevent the As a result of the foreign matter, the water separation device 37 cannot be switched, and all of the cleaning tanks 22 cannot be cleaned, so that a highly reliable cleaning device can be improved. As shown in FIG. 14, the inlet 38 for the washing water to flow into the valve housing 40 The center line K of the valve body is 15 away from the center of rotation l of the valve body 41 by a distance M from the outer circumference side. Inside the valve housing 40, a vortex that rotates in the valve housing 40 occurs, which accounts for most of the foreign bodies. The foreign matter having a larger specific gravity than water is pushed toward the circumference of the shell 40 by the centrifugal force of the vortex. In this way, the foreign matter tends to be far away from the shaft 60 and the hole 61 located near the center of the valve housing 40, and the probability of foreign matter getting caught in the gap between the shaft 60 and the hole 61 can be further reduced. 20 The valve body 41 moves upwards to wash The pressure of working water is working. Since the wide shell 40 is usually pressurized to about 20 ~ 40kPa, the valve body 41 acts on the valve body 41. Although it varies depending on the size of the valve body 41, it is generally between 20 and 100N. The valve body 41 can be moved even if some foreign matter gets stuck. However, when the valve body 41 is lowered, only the body weight of the valve body 41 functions, and its driving force is small. 38 1231201 Therefore, as shown in FIG. 22 It is shown that by providing an elastic force applying device 62 that separates the valve body 41 from the outflow port 39, and abutting the valve body 41 with a coil spring, the valve body 41 can be moved even when a foreign object is caught, thereby improving switching Reliability. In addition to the coil spring shown in Figure 22, you can also use other springs such as 5 leaf springs, rubber, and other elastomers, or fix metal accessories to the valve body 41 or insert molding It is also possible to increase the weight of the valve body 41 The same effect can be achieved. In addition, a structure in which a magnet or a magnetic body is provided on the valve body 41 and the valve body 41 is pushed downward by magnetic force can also be adopted. · 10 In addition, the shape of the shaft 60 and the hole 61 may not be limited to the first. The shape shown in FIG. 15 is similar to the shape in which the middle of the shaft 60 shown in FIG. 23 is cut, the shape shown in FIG. 24 is a closed hole without the hole 61, and FIG. 25 is shown. Various schemes, such as a hole 61 in the valve housing 40 and a shaft 60 in the valve body 41, can be used, and they can reliably prevent foreign matter from getting stuck in. 15 (Embodiment 3) Figures 26 to 28 show A case where the facing surface of the outflow port 39 and the valve body 41 is other than a planar shape. ® Fig. 26 shows the case where the facing surfaces of the outlet 39 and the valve body 41 are conical. As shown in the figure, the opposite surface is slightly inclined from the horizontal. In this way, when the valve body 41 is separated from the outflow port 39, the possibility of the stuck foreign body 49 staying on the valve body 41 can be reduced, thereby providing a method for removing the foreign body 49. Water distribution device 37 with higher function. In addition, the direction of the rotation axis is inclined from the horizontal direction regardless of the direction in which it is set, which can produce a good effect. In addition, even when the outlet 39 and the valve body 41 are in contact, the valve body 39 1231201 41 can be rotated, and the switching of the knee washing water is independent of the linear motion distance, which can improve the degree of freedom during design. In addition, when the structure in which the washing water flowing out of the U port 39 shown in the figure contains a horizontal curve is used, the conical outflow port 39 contains the pressure loss of the knife-shaped water in the normal (horizontal) direction. Can be lowered. In addition, the distance separated by the valve body 41 is the distance between the faces, and the dimension C in the figure is the distance. There is no particular limitation on the taper angle D of the cone portion. However, the movement of the sleeve-shaped effect valve body 41 will become impossible when it is close to 0 degrees. In order to ensure the necessary clearance, the linear movement distance will be longer, and the inter-shell 40 will also become larger. Therefore, the taper angle D of the conical portion should be more than 30 degrees, and preferably more than 90 degrees. Fig. 27 shows a case where the facing surface of the outflow port 39 and the valve body 41 is a pyramid-shaped sun guard. Since the opposite surface is also inclined from the horizontal, it can play the same role as a cone. In addition, the opposite surface between the outflow port 39 and the interbody 41 is substantially flat, and can be managed by the flatness and angle of the opposite surface. 15 ^ Even in the case of mass production, a water distribution device 37 with low leakage and stable performance can be produced by using components of a predetermined size. In addition, FIG. 28 shows the case where the opposite surface between the outflow ports 39 and _41 is a spherical surface. In the case where the valve body 41 is slightly inclined opposite to the outflow port 39 2, although the positions of the opening 42 and the outflow port 39 may be slightly misaligned, the flow * port 39 and the valve body 作为, which are opposite surfaces, are spherical surfaces. Therefore, the gap between the outflow port 39 and the valve body 41 is not widened, the leakage of the washing water is not enlarged, and the switching performance can be maintained. (Example 4) The shape of the outflow port 39 shown in FIG. 29 is a fan shape, and the opening portion 42 of the valve body 41 shown in FIG. The structure, function, and effect are the same as those of the second embodiment. The shape of the melon outlet 39 is a general shape. When a plurality of outflow outlets 39 are arranged around the shaft, the shape E formed by these outflow outlets 39 is substantially circular. Under the condition that the same area of the outflow port 39 is ensured, this shape can minimize the shape of the valve body 41, and ensure a sufficient gap between the valve body 41 and the valve housing, and can prevent foreign objects from getting stuck. Miniaturization of the water device 37. 10 15 In addition, if the outer shape of the valve body 41 is substantially circular, it is difficult to trap foreign objects between the valve body and the valve housing 49, the probability of poor switching can also be reduced, and 'due to the resistance when the valve body 41 is moving, The movement of the wide-body salamander is more muddy, and the sundial is also different. Unfortunately, the time for the cleaning pump to stop working is shortened, and the cleaning is performed in a shorter time. As in 3GBI, the openings are made into cutout shapes that are connected to the outer shape of the carcass. Even when foreign matter 49 is to be sandwiched between the outlet 39, the valve housing 4G, and the opening, the foreign matter 49 There are also places to avoid 'so that the probability of getting stuck can be reduced. In addition, the upper age member 44 on the side of the nucleus core 40 and the part of the partition wall flowing out of the nucleus serve as each other 'and are provided between the phase_flow outlet%. In this way, there are no replacement parts inside and outside of the flow 2 port, and the size (outer diameter) of the valve body can be minimized while ensuring the same outflow area, and the water distribution device 37 can be miniaturized. (Embodiment 5) FIG. 31 shows a structure in which the water separation device 37 can be disassembled. This figure is an oblique view of the bottom of the β-washing tank 22, and the cover can be disassembled by rotating and removing the cover. In this way, the inside of the water separation device 37 can be cleaned and processed. If there is a situation that the switch cannot be performed, maintenance operations such as removing foreign objects 49 can be performed, so that the switch can be reliably performed. use. 5 Specially, if the structure that can be disassembled from the inside of the washing tank 22 is used, maintenance work can be performed without disassembling the main body 20 of the dishwasher, and users can also perform maintenance work themselves, making maintenance work very easy. In addition, in addition to the above-mentioned structure in which the cover 53 and the screw are integrated, 10 can also be used to remove the screw and then remove the structure. After the cover W is inserted, it can be removed by pressing the claws and then pressing it. Structure and other methods. In addition, instead of disassembling from the inside of the cleaning tank 22, maintenance can be easily performed if it can be easily disassembled from the bottom surface. In addition, if the opening position of the valve housing 40 is provided in the cleaning tank 15 22 as in the present embodiment, the cleaning tank 22 and the valve housing 40 can be constituted by one member. In the case of attack, the danger of water leakage from the water separation device 37 is no longer present. (Embodiment 6) FIG. 32 is a plan view of a valve body 41. On the shaft 60 protruding from the lower side of the valve housing 40, a rib-shaped protrusion 63 extending in the axial direction is provided on the shaft 60 to form a 20-degree approach. Pieces. The other basic configurations are the same as those in the second embodiment. As in the second embodiment, the cleaning pump 26 repeatedly moves on and off the private body valve valve 41 which moves up and down, and rotates 90 degrees each time to sequentially switch the washing device 27 that sprays washing water. The four protrusions 63 provided on the shaft 60 play a role of approaching the "卩". When the shaft 60 contacts or approaches the hole 61, the valve body 41 moves linearly while 42 4231201 rotates. Since the space 63a larger than the proximity member (projection portion) 63 and the proximity member (projection portion) 63 will be formed, there are only 4 points of the proximity portion where foreign matter may be caught. It's even harder to get stuck. -5 As shown in Figure 33, once a foreign object 49 is caught, the valve body 41 can be easily removed just by turning the foreign object slightly. This can prevent the foreign object from catching the valve body 41 and making it impossible to switch. If the upper engaging member 44 is not set as shown in FIG. 34, when the water flow of the washing water stops or decreases, the valve body 41 starts to move at the same time as a rotation action (moves below the slant 10 as shown by the arrow), then foreign matter 49 moves toward the wide space portion 63a between the approaching portion (projection. 卩) 63 and the approaching portion (projection) 63 as shown in FIG. 35, so that it can be reliably removed. If the gap between the adjacent approaching portions 63 is set to be larger than the mesh size of the leftover filter 29, it is possible to more reliably prevent the foreign matter from being clogged. Generally, the 15 leftover filter screen 29 is formed of a metal sheet or the like with a large number of small holes, and it may be set to be larger than its aperture (about 1mm to 2mm). However, in the case of detachable filters and fixed filters, it is best to set a gap larger than the size of the fixed filters. In addition, the outer peripheral sides of the shaft 60 and the hole 61 may be provided with the lower part 20 engaging members 45 as described above. As shown in FIG. 36, at the position of the valve body 41 in a state where the washing pump 26 is operated and washing water passes, the convex portion 63 is arranged to be aligned with the phase of the lower engaging member 45 provided on the valve body 41 side. Adjacent to the top 64. Since the engaging member 45 is a triangle as shown in the figure, the engaging member 45 and space interact with each other. There is a high possibility that the foreign matter may be caught in the spray fitting 43 from the space part with the water flow in the valve housing 40 Ϊ231201 between the component 45 and the shaft 60. high. The top portion 64 and the raised portion are the same. 'Although the possibility of foreign objects getting caught in the gap is increased, the opposing area is reduced by making the raised portion 63 face the middle of the adjacent top portion 64. The possibility of foreign objects getting stuck in the gap is reduced. -As shown in FIG. 37, a recessed portion 65 having no slope is provided between the adjacent top portion 64 · and the top portion 64 so that the recessed portion ^ disc protruding portion 63 is opposed to each other, and the shaft 60 and the lower portion are joined together. The situation where foreign matter is caught between the parts 45 can be completely avoided. In addition, in this case, if the number of the protrusions ^ and the number of the tops 64 of the coupling member 45 are made the same, the relationship of all the protrusions # 10 部 63 has the same conditions, and the stability to foreign objects Can be further improved. (Embodiment 7) Fig. 38 is a plan view of a valve body 41. The valve housing 40 and the valve body 41 are substantially circular. The outer peripheral portion of the valve body 41 is provided with a plurality of protrusions (approach members). , 15 Under the function of the convex portion (proximity member) 63 provided on the outer circumference of the valve body 41, the valve body 41 and the valve housing 40 contact or approach each other to form a structure that restricts the movement of the valve body 41 ' A space portion 63a having a larger volume than the proximity member 63 and the proximity member 63 is interposed. In the valve body 41, only the approaching part 63 will approach the valve housing 40, and the area where foreign matter may be caught will be reduced, and the reliability against foreign matter can be improved. In addition, as in Embodiment 6, even if there is a foreign object caught in the proximity member 63, it is easy to remove the valve body 41 as long as the valve body 41 is slightly rotated, which can avoid the situation where the foreign body gets stuck in the valve body 41 and cannot be switched. . In addition, when the flow of the washing water stops or decreases, if the valve body 41 starts to move at the same time when 44 1231201 = moves, even if there is a wide space between the approaching member 63 and the approaching member 63, the approaching member 63 will inevitably be widened. Spatial movement can be eliminated, and in most cases, the situation that cannot be switched due to foreign objects can be avoided. 5 If the gap between the adjacent proximity members 63 is set to be larger than the size of the leftover filter 29, foreign matter can be reliably prevented from being caught. Usually, the leftover filter screen 29 is formed of a perforated metal sheet or the like, and it may be set larger than its aperture (1 to 2 degrees). In the case where there is no attaching / detaching crossover and fixed crossover, it is best to set a gap larger than the size of the fixed screen. spring

10 In addition, the same effect can be obtained when the protrusion ° 卩 63 is not provided on the valve body 41-side but on the limb 4G-side. In addition, the proximity member is not limited to the shape of the convex portion 63, and may have various shapes such as the 39th shape of the carcass "made oval, and the portion shown by ® towel letter N is the proximity member. '15 According to the present invention as described above, even when foreign matter is caught in the gap between the valve body and the valve body, the foreign matter can be easily removed, and the cleaning device with the washing water supply can be reliably performed. In addition, repair can also provide a water distribution device that can prevent foreign objects from getting stuck, less water leakage, and high branching efficiency. 20 [Simplified illustration of the drawing] FIG. 1 is a table of the dishwasher in the embodiment of the present invention.
