Description

Western flush toilet {WESTERN WATER CLOSET}

2. Description of the Related Art A Western-style flush toilet is known which has a ceramic toilet bowl and a cleaning device provided on the rear of the western toilet bowl main body and having a cleaning tank such as a low tank capable of discharging the washing water. The western-style toilet main body has a rim formed in a toilet part and an upper edge of the toilet part, and has a rim water channel therein, through which the washing water can flow down the toilet part. And a trap connected to the lower end of the toilet bowl. The trap part is provided with the jet port so that the washing water may be jetted along the trap part. The washing apparatus is connected to a water supply pipe such as a water pipe through which the washing tank supplies the washing water, and is configured to discharge the washing water stored in the washing tank to the rim channel.

Among the rims, the so-called open rim exposing the rim passageway to the toilet part consists of an upper wall part projecting almost horizontally inwardly from the upper edge of the toilet part, and an inner wall part extending in a substantially vertical direction from the inner end of the upper wall part. A rim channel is formed inside to guide the washing water discharged from the washing apparatus. In this open rim, the washing water in the rim channel passes through the opening formed by the inner wall portion and the toilet bowl to be directed toward the toilet bowl.

Among the rims, the so-called closed rim which does not expose the rim passageway to the toilet bowl includes an upper wall portion projecting substantially horizontally inwardly from the upper edge of the toilet portion, and an inner wall portion extending in a substantially vertical direction from the inner end of the upper wall portion; The lower wall part which connects the lower end of an inner wall part with a toilet bowl part is formed, and the same rim channel is formed inside. In this closed rim, a plurality of water catchers opening toward the toilet bowl are provided in the lower wall portion, and the washing water in the rim channel passes through the water catchers and is discharged toward the toilet bowl.

Thus, in the conventional Western flush toilet, the toilet bowl is cleaned by the washing water discharged from the washing apparatus.

Moreover, in the conventional western-style flush toilet, a toilet part and a trap part are comprised by the ceramic toilet bowl main body, the jet port is comprised by the jet nozzle separate from the western toilet bowl main body, and this jet nozzle is comprised by the piping for a jet. It is connected with a washing | cleaning apparatus.

In such a Western-style flush toilet, the washing water discharged from the washing apparatus is supplied to the rim channel, whereby washing of the toilet bowl and securing of running water are performed. In addition, the washing water is also supplied to the jet port through the jet pipe, thereby forcibly generating a siphon effect so that dirt can be discharged even with a small amount of washing water. For this reason, in this western-style flush toilet, the maintenance cost by saving water can be reduced. Moreover, in this western-style flush toilet, since the western-style toilet main body made of ceramics is comparatively simple shape, manufacturing cost can be reduced.

In addition, it is known to provide a barrier material under the trap part as a western flush toilet, and also to surround the jet pipe with another barrier material.

In this Western-style flush toilet, even when the difference between the water temperature and the room temperature is large and the humidity is used in an environment with high humidity, since the trap part and the pipe for jet can be insulated mainly by the barrier material, condensation on the outer surface of the trap part and the jet pipe is prevented. You can prevent it.

For example, in the western-style flush toilet shown in FIG. 28, the toilet part 91 which has the foot surface 91a by the Western-style toilet main body 90 made from ceramics, and the bottom part of this toilet part 91 The trap part 92 is provided so that it may be continued. The uppermost part of the trap part 92 becomes the upper side wall surface 92a comprised from the curved surface, and the upper side wall surface 92a is connected to the lower drain port 92b. The drain port 92b is connected to a drain pipe not shown through the drain socket 98.

In addition, a jet chamber 94 connected to a jet channel, not shown, is formed at the bottom of the toilet 91, and at the bottom of the flowing portion of the trap 92 to secure the flow of water, the bottom of the jet chamber 94 communicates with each other. The jet port 93 penetrates. In addition, a water supply chamber 95 is formed in the upper part of the rear part of the toilet part 91, and the water supply chamber 95 is connected to the low tank which is not shown by the distributor 97 which is a part of the washing | cleaning apparatus. In addition, a rim 96 having a rim channel 96a therein is formed above the toilet 91.

In this Western-style flush toilet, washing water is supplied from the low tank to the jet chamber 94 and the rim passage 96a through the distributor 97 and the water supply chamber 95. The washing water supplied to the jet chamber 94 is jetted from the jet port 93 toward the trap portion 92. In addition, the washing water supplied to the rim water passage 96a flows out of a water hole not shown in the figure provided at the lower end of the rim 96 to clean the foot surface 91a of the toilet bowl 91. At this time, in this Western-style flush toilet, since the siphon action is forcibly caused by the washing water jetted from the jet port 93, the ability to discharge the dirt is large.

In addition, the Western-style flush toilet shown in FIG. 29, 30 wash | cleans the western-style toilet main body 91 made from earthenware, the washing tank (not shown), the distributor 92, etc. which supply cleaning water to this western-style toilet main body 91. It is equipped with a device. The western-style toilet main body 91 has a toilet 93 and a rim channel 94a formed at the front circumference of the upper edge of the toilet 93 and capable of flushing the wash water to the toilet 93. And a trap portion 95 connected to the lower end of the toilet portion 93. A drain socket (not shown) extending up and down is connected to the discharge port 95c of the trap portion 95, and the drain socket is connected to a drain pipe not shown, which protrudes from the floor surface.

In this Western-style flush toilet, the washing water stored in the washing tank is supplied to the rim channel 94a through the distributor 92, from which the washing water flows into the toilet 93. The washing water which wash | cleans the toilet part 93 generate | occur | produces the siphon effect by the trap part 95, and is discharged to the back side along with the trap part 95 with dirt.

Moreover, in the general western flush toilet, a metal drain flange is connected with the drain pipe which protruded from the floor surface, and the discharge port of a trap part is connected with the metal drain flange.

In this western-style flush toilet, washing of the toilet part is performed with the washing water supplied from the washing tank. And when the wastewater which may contain the dirt with washing water is partly blocked at the end formed in the trap part when discharged through the trap part, turbulence arises and a water film is formed. By the action of the water film thus formed, the trap part is brought into a full state by sewage, and the sewage in the full water state is discharged so that the water film is pulled to the drain pipe side by the breakage of the water film.

{1st, 2nd invention}

However, in the conventional Western flush toilet, since the inner surface of the rim protrudes inward from the foot of the toilet, contamination is liable to adhere to the rim, and furthermore, an odd smell or the like tends to occur, and it is easy to be unsanitary.

That is, in the open rim of a conventional Western flush toilet, contamination due to urine scattering or splashing during stool discharge, which occurs when the toilet is used, is likely to adhere to the rim channel, which is the back side of the upper wall or the back side of the inner wall. . Moreover, in the closed rim of a conventional Western flush toilet, their contamination is apt to adhere to the inner rim channel through the rear side or the catcher port of the lower wall part. Since the contaminants adhered to these rims are in a position where it is difficult to see by the cleaner, it is difficult to confirm the situation of attachment and removal, and the cleaning is likely to be incomplete. For this reason, these contaminations are likely to remain there and become a source of odors such as ammonia odors, which may be unpleasant to the user and unsanitary.

The first and second inventions are made in view of the above-mentioned conventional situation, and the first problem to be solved is to provide a hygienic Western-style flush toilet which is hard to adhere to the rim, furthermore, strange smells and the like are not generated. , It is set as two problems.

Western-style flush toilet of the first invention, Western toilet body having a toilet portion, a rim formed on the upper edge of the toilet portion and having a rim passageway therein,

In the Western flush toilet provided with a washing device capable of discharging the washing water in the rim channel, the washing water discharged from the cleaning device is provided for cleaning the toilet portion via the rim channel,

The rim is characterized in that at least the front side has the same inner surface as the foot surface of the toilet bowl.

In the Western-style flush toilet of the first aspect of the invention, since at least the inner surface of the rim is flush with the foot of the toilet bowl, contamination is hardly adhered to the rim. For example, if the figure is an open rim, dirt is less likely to adhere to the rim passage, which is the back side of the upper wall portion or the back side of the inner wall portion. In addition, if the figure is a closed rim, sewage is less likely to be attached to the inner rim channel through the surface or catcher of the lower wall.

In addition, in the western flush toilet of the first aspect of the invention, since the inner surface of the rim is the same surface as the foot of the toilet bowl, there is contamination at a position that is easy to see by the cleaner, and at the time of cleaning, It is easy to wipe the dirt. For this reason, the cleaning can also be performed sufficiently.

At least the western-style flush toilet of the first aspect of the invention can obtain the minimum effect of the first aspect of the invention, provided that the inner surface of the rim is flush with the foot of the toilet portion. This is because contamination caused by urine scattering or splashing during fecal discharge that occurs when the toilet is used is likely to be located in the front. In this respect, it is preferable that the inner surface of the rim is the same surface as the foot surface of the toilet bowl at all the leading edges of the toilet bowl. This prevents adhesion of the sewage to the rim due to urine scattering occurring at the time of use of the toilet, springing at the time of fecal discharge, or the like, at any position in the upper part of the toilet, thereby producing the effect of the first invention reliably. Can be.

In addition, the Western-style flush toilet of the second invention, Western toilet body having a toilet portion, a rim formed on the upper edge of the toilet portion and having a rim passageway therein,

In the Western flush toilet provided with a washing device capable of discharging the washing water in the rim channel, the washing water discharged from the cleaning device is provided for cleaning the toilet portion via the rim channel,

The rim is characterized in that at least in the front, the inner surface is located outside the foot of the toilet bowl.

In the western-style flush toilet of the second aspect of the invention, since at least the inner side of the rim is located outward of the foot of the toilet bowl, contamination is hardly attached to the rim.

In addition, in the western flush toilet of the second aspect of the invention, since the inner surface of the rim is located outward from the foot of the toilet portion, the contamination is present at a position that is easy to see by the cleaner, so that the cleaning can be performed sufficiently. do. However, the ease of wiping during cleaning is slightly inferior to the western-style flush toilet of the first invention.

In the western-style flush toilet of the second invention, at least on the front side, if the inner surface of the rim is located outward from the foot of the toilet bowl portion, the minimum effect of the second invention can be obtained. And it is preferable that the inner surface of the rim is located outward of the foot of the toilet bowl at all stages of the toilet bowl.

It is preferable that the western-style toilet main body which concerns on 1st, 2nd invention has the edge part which forms a rim channel in the boundary of a toilet part and a rim. This is because the washing water discharged from the cleaning device does not immediately flow into the toilet bowl, but rather flows out into the toilet bowl gradually while turning sufficiently in the rim channel, thereby improving the cleaning effect of the entire toilet bowl.

In the Western flush toilets of the first and second inventions, the rim channel may be opened around the circumference between the inner surface of the rim and the foot surface of the toilet bowl. That is an open rim. In this way, the advantage of manufacturing cost can be acquired.

On the other hand, in the Western flush toilets of the first and second inventions, the rim channel can be opened by a catcher between the inner surface of the rim and the foot surface of the toilet bowl. That is the closed rim. In this case, although there is a disadvantage in manufacturing cost, since the amount of water stored in the toilet bowl is easy to be adjusted by the catcher, the cleaning ability of the entire toilet bowl can be improved.

{Third invention}

However, in the conventional Western-style flush toilet, if it is used in a cold district, for example, there is a fear that the washing water in the trap part is frozen, which makes it impossible to use the cold chamber or destroys it.

It is also conceivable to provide a heater below this trap part. In this case, even when used in a cold region, the trap portion can be heated by the heater, so that freezing of the washing water in the trap portion and the like can be prevented, and the usable state of the cold phase and prevention of destruction can be realized.

However, in such a Western-style flush toilet, even if the heater is provided in a trap part, for example, the washing water in the jet pipe may freeze. In particular, this Western-style flush toilet has a larger tendency than the conventional one in which the western-style toilet main body has a jet channel because the jet pipe is separate from the western-type toilet main body provided with a heater. At this time, if the jet pipe is heated by a heater different from the heater that heats the trap part, the manufacturing cost increases significantly. In this way, the manufacturing cost and maintenance cost can be reduced, and the maintenance and destruction prevention of the usable state in the cold term are incompatible.

The third invention has been made in view of the above-mentioned conventional situation, and has to be solved to provide a Western-style flush toilet capable of attaining a reduction in manufacturing cost and maintenance cost, and prevention of maintenance and destruction of the usable state in the cold season. We assume three problems.

The western-style flush toilet of the third invention includes a toilet section, a trap section connected to a lower end of the toilet section, and a jet port provided in the trap section to eject washing water along the trap section. The trap part is constituted by a Western-style toilet body made of pottery, and the jet port is a western-style flush toilet configured by a jet nozzle connected by a cleaning device capable of discharging the cleaning water and a jet pipe.

The jet pipe is heated by a heater for heating the trap part.

In the Western-style flush toilet of the third aspect of the invention, since the pipe for jet is heated by a heater for heating the trap part, the freezing of the washing water in the jet pipe can be prevented even when used in a cold district. For this reason, the maintenance cost by water saving can be reduced, and the maintenance of the usable state in a cold and prevention of destruction can be compatible. In addition, since an independent heater for jet piping is unnecessary, the manufacturing cost can be reduced.

It is preferable to employ | adopt what made the surface shape as a heater. Such heaters are known. With such a heater, the trap part can be easily enclosed, and the effect of the third invention can be realized by placing the jet pipe in the vicinity of the heater. Moreover, with such a heater, the trap part and the piping for jet can be easily enclosed, and the effect of the 3rd invention can be implement | achieved.

The Western toilet body may be formed with an opening for guiding the inside of the jet pipe. On the other hand, the heater is usually provided with a cord that is connected to an external power source. It is preferable to open this cord in the opening formed in the western-style toilet main body. Otherwise, an opening for inserting the cord must be separately formed in the western toilet bowl body, which makes manufacturing the western toilet bowl body cumbersome, resulting in an increase in manufacturing cost, and deterioration in appearance. Such an opening is preferably penetrated at a position that is easy to see from above. This is because the assembly of the Western flush toilet is improved.

As the washing apparatus, in addition to a conventionally known washing tank, one that can be directly connected to a water supply pipe such as a water pipe for supplying washing water from the outside and capable of discharging the washing water by opening and closing the valve can be adopted. The effect of 3rd invention is large when employing the latter washing | cleaning apparatus. The former washing apparatus stores and discharges the washing water once, and is heated by another heater or the like during storage, and it is relatively easy to prevent freezing of the washing water in the jet pipe. This is because, since new washing water is discharged from an external water supply pipe, washing water existing outside flows into the jet pipe, and freezing there is likely to occur in the cold season.

{4th invention}

However, in the conventional Western-style flush toilet, the production cost increases because the barrier material of the trap part and the barrier material of the jet pipe are separate bodies.

The fourth invention has been made in view of the above-described conventional situation, and a fourth problem to be solved is to provide a Western-style flush toilet capable of realizing a reduction in manufacturing cost.

The western-style flush toilet of the fourth invention includes a toilet section, a trap section connected to a lower end of the toilet section, and a jet port provided in the trap section to eject washing water along the trap section. The trap part is constituted by a Western-style toilet body made of pottery, and the jet port is a western-style flush toilet configured by a jet nozzle connected by a cleaning device capable of discharging the cleaning water and a jet pipe.

The jet pipe is discharged by a barrier material which discharges the trap part.

In the western-style flush toilet of the fourth aspect of the invention, since the jet pipe is discharged by the barrier material which discharges into the trap part, the barrier material of the jet pipe is not required, and the manufacturing cost can be reduced.

The Western toilet body may be formed with an opening for guiding the pipe for the jet inside. In the case of having such an opening, the opening needs to be sealed. Otherwise, new air containing moisture penetrates into the interior including the trap portion and the pipe for the jet, resulting in inferior effect. Such an opening is preferably penetrated at a position that is easy to see from above. This is because the assembly of the Western flush toilet is improved.

As the washing apparatus, in addition to a conventionally known washing tank, one that can be directly connected to a water supply pipe such as a water pipe for supplying washing water from the outside and capable of discharging the washing water by opening and closing the valve can be adopted. The effect of 4th invention is large when employing the latter washing | cleaning apparatus. The former washing device stores and discharges the washing water once. Since the washing water in the jet pipe tends to be equal to the temperature in the toilet at the time of storage, condensation is unlikely to occur on the outer surface of the jet pipe. This is because, since new washing water is discharged from an external water supply pipe from time to time, the washing water existing in the jet pipe flows easily, causing a temperature difference easily inside and outside the jet pipe, and condensation therein if a barrier material is not provided.

{5th invention}

However, in the conventional western flush toilet, when the rinsing device is provided to discharge the washing water from the left and right in the rim channel, whether the rim is the open rim or the closed rim, the washing water is in the rim channel and / or the toilet. Because they collide in front of wealth, strange sounds are produced during collisions, resulting in lack of quietness. Moreover, in such a Western-style flush toilet, the washing water may scatter to the floor surface due to the collision of the washing water in front of the toilet bowl, and the floor surface may be wetted.

In this regard, if the western flush toilet adopts a closed rim, for example, even if the cleaning device is provided in the rim channel to flush the washing water from both sides, the washing water is easily turned in the toilet bowl, By inclining the catcher penetrating the lower wall portion to secure the discharge performance, as a result, the collision at the front of the toilet bowl portion of the washing water can be alleviated to achieve a certain level of quietness while preventing the scattering of the washing water on the floor surface. can do. However, with this, the structure of the rim is complicated because it must penetrate exactly through the sand shooter, and the number of manufacturing processes increases, and further, the manufacturing cost rises. In addition, in this Western-style flush toilet, the mixing of the washing water and the air occurs in the closed rim at the start of washing, and since the mixed water is taken out from the plurality of catching holes, it is easy to produce strange sounds at this time, too. have. Thus, as long as the closed rim is adopted, for example, even if the cleaning device is provided to discharge the washing water from one direction in the rim channel, problems of the rise and quietness of these manufacturing costs may remain.

The fifth invention has been made in view of the above-mentioned conventional situation, and is excellent in quietness and has no fear of wetting the floor surface. It is excellent in washing ability of toilet bowl and discharge performance of dirt, and it is possible to realize lower cost of manufacturing unit. To provide a fifth task to be solved.

Western-style flush toilet of the fifth invention, Western toilet main body having a toilet, a rim formed in the upper edge of the toilet and having a rim passageway therein, and a trap connected to the lower end of the toilet,

In the Western flush toilet provided with a washing device capable of discharging the washing water in the rim channel, the washing water discharged from the cleaning device is provided for cleaning the toilet unit via a singer rim channel,

The rim exposes the rim channel to the toilet bowl, and the cleaning device is provided so as to discharge the washing water from one direction in the rim channel.

In this western-style flush toilet, the washing water is discharged from the washing apparatus toward the rim channel. Since the flushing water is discharged from only one direction, the flushing water flows gradually into the toilet section while guiding the inside of the rim channel in one direction, and turns the toilet section in one direction (turns to one side) and is discharged through the trap section. do. For this reason, no strange sound occurs because the washing water does not collide in the rim channel and / or in front of the toilet bowl. In this Western-style flush toilet, since the open rim exposes the rim channel to the toilet, mixing of the wash water and air does not occur at the start of cleaning, and the wash water passes through an opening wider than the catch port of the closed rim. At this time, strange sounds do not occur because they are shot. For this reason, quietness is excellent.

Moreover, in such a Western-style flush toilet, since the collision of the washing water from the front of the toilet part does not occur, there is no scattering of the washing water and the floor surface is not wetted. Moreover, in this western-style flush toilet, the washing | cleaning ability of a toilet part can be ensured by strengthening the force of washing water. Also, since the flushing water is discharged while turning the toilet bowl in one direction (turning to one side), the waste water discharge performance is also excellent.

In addition, since this Western-style flush toilet does not have a water catcher, the structure of the rim is simplified, the number of manufacturing steps is small, and further, the manufacturing cost can be reduced.

It is preferable that the western-style toilet main body which concerns on 5th invention has a partition which isolate | separates a rim channel from a rear side. In this case, since the washing water is not guided to the rear side, there is no wasteful use of the washing water and the water saving effect is high.

Moreover, it is preferable that the western-style toilet main body which concerns on 5th invention has the edge part which forms a rim channel in the boundary of a toilet part and a rim. In this case, since the end portion reliably forms the rim channel, the washing water discharged from the washing apparatus is easily guided to the downstream side, and the washing in the toilet bowl is sufficient, and the discharge performance of the dirt can be further improved.

It is preferable that this end part is formed so that the washing water may be guided to the toilet part and the downstream side on the upstream side of the washing water discharged from the washing apparatus, and the washing water may be guided only to the toilet part on the most downstream side. In this case, since the washing | cleaning water discharged from a washing | cleaning apparatus does not flow to the toilet part immediately from the upstream side of a rim channel, it is guided to the most downstream side and flows into the toilet part, and washing | cleaning in a toilet part can fully be performed. Moreover, by this, the washing water is easy to turn in the toilet bowl, and the waste discharge performance can be improved. In addition, since the washing water is guided only to the toilet part at the downstream side, the washing water is not circulated again, or left in the rim channel, etc., so that the use of the washing water is unnecessary and the water saving effect is high.

{Sixth invention}

However, in the conventional Western-style flush toilet shown in FIG. 28, the washing water jetted by the jet port 93 from the cleaning device by the position and shape of the upper side wall surface 92a of the trap portion 92 is the upper side wall surface. By 92a, it is reflected in various directions. In addition, when the washing water is not reflected toward the drain passage 92b of the trap portion 92 by the upper side wall surface 92a, the washing water is subjected to a large resistance until reaching the drain opening 92b. In addition, the washing water reflected by the upper side wall surface 92a may collide with each other. Therefore, drainage property may fall and it may become a cause of the fall of siphon action. In order to compensate for such a decrease in siphon action, that is, a decrease in the ability to discharge dirt, a large amount of washing water must be used.

The sixth invention has been made in view of the above-described conventional situation, and has a sixth problem to be solved by providing a Western-style flush toilet capable of sufficiently discharging dirt with a minimum amount of washing water.

The western-style flush toilet of the sixth aspect of the invention has a toilet bowl, a trap section connected to a lower end of the toilet bowl section, and a western-style flush toilet comprising a jet port provided in the trap section to eject washing water along the trap section.

The trap portion is characterized in that a reflecting surface for reflecting the washing water jetted from the jet port toward the drain port of the trap part is formed.

In the western flush toilet of the sixth invention, a reflecting surface for reflecting the washing water jetted from the jet port toward the drain port of the trap part is formed in the trap part. For this reason, the reflected washing water is discharged to the drain port without colliding with the wall surface on the downstream side of the reflecting surface, and the washing waters are less likely to collide with each other. This improves drainage and makes the siphon action strong.

It is preferable that the reflecting surface reflects the washing water jetted from the jet port in the vertical direction. As a result, the reflected washing water is further discharged by gravity. This further improves drainage, makes siphoning stronger, and increases the ability to discharge dirt.

In addition, it is preferable that the reflecting surface equals the angle formed by the imaginary line perpendicular to the reflecting surface and the jetting direction of the washing water by the jet port, and the angle formed by the center line of the imaginary line and the drain port. In this case, since the washing water sprayed from the jet hole is guided toward the center of the drain water by one reflection by the reflecting surface, the washing water reaches the drain hole while maintaining the force, and the siphon action is strongly enforced by the high drainage property. can do. On the other hand, otherwise, since the washing water injected from the jet port collides with the drain several times, the washing water has a large resistance, resulting in a large decrease in discharge rate, low drainage, and a low siphon action.

The jet port is preferably provided to eject the washing water along the lower wall surface of the trap part. The dirt which may remain in the flowing water is settled on the lower side wall surface of a trap part with passage of time. For this reason, if the jet port ejects the washing water along the lower wall surface of the trap part, the sediment can be discharged without leaving the trap part, so that the dirt can be discharged reliably.

The lower part of the trap part which ensures the flow of water is a storage part which stores a small amount of slurry as much as possible at the time of baking injection molding, and it is continuous with this storage part, and is parallel to the injection direction of the washing water by a jet hole. It is preferable that the lower side wall surface is extended. The ceramic toilet bowl body constituting the Western-style flush toilet of the sixth invention is generally molded by vane injection molding because of its complicated shape. When molding in this way, it is convenient that the storage part stored for discharging a slurry is provided in the lower part of the flow part of the trap part which ensures flowing water. If such a storage part stores a large amount of slurry, the lower side wall surface of the trap part continuous with this storage part will not extend in parallel with the injection direction of the washing water by a jet port. In this way, the deposit which precipitated on the lower side wall surface of a trap part is easy to remain in a trap part. On the other hand, if the reservoir stores the slurry as little as possible, the lower wall surface of the trap can extend in parallel with the jetting direction of the washing water by the jet port. In this case, the precipitate which precipitates on the lower side wall surface of the trap part is hard to remain in the trap part.

As a washing | cleaning apparatus, besides washing tanks, such as a conventionally well-known low tank, the thing which can be directly connected to water supply pipes, such as a water pipe which supplies washing water from the outside, and which can discharge washing water by opening and closing of a valve | bulb can be employ | adopted. The effect of 6th invention is large when employing the latter washing | cleaning apparatus. In other words, when the jet port is connected to the latter cleaning device, the washing water with high force is more likely to be ejected from the jet port than when the jet port is connected to the former cleaning device.

{Seventh invention}

However, in the said conventional western-style flush toilet shown in FIG. 29, the miniaturization of the western-style toilet main body 91 is not examined, and it is easy to enlarge it as a whole. For this reason, in recent years, space saving is not aimed at, and the toilet which cannot secure a comparatively large space is further narrowed.

The seventh invention has been made in view of the above-mentioned conventional situation, and has a seventh problem to be solved by providing a Western-style flush toilet with miniaturization.

In order to solve the above problems, the inventors earnestly examined and came to complete the seventh invention by paying attention to the front end of the trap part, the rear wall of the trap part, and the toilet seat attachment hole forming the running water in the toilet part.

That is, the western-style flush toilet of the seventh aspect of the invention includes a toilet bowl body and a western toilet bowl body having a trap part connected to a lower end of the toilet bowl, and the toilet bowl is washed with washing water, and the rear part is flush with the trap part. In the Western-style flush toilet for draining the washing water,

The front end of the trap part forming the running water in the toilet part is located before the rear end of the toilet part.

As shown in Fig. 29, the conventional western-style flush toilet has a toilet 93 at the front end 95d of the trap 95 that forms a running water in the toilet 93 in the western toilet main body 91. Be sure to be located behind the rear end 93a. For this reason, the total length of the western-style toilet main body 91 comprised by the toilet part 93 and the trap part 95 becomes inevitably long. On the other hand, in the western-style flush toilet of the 7th invention, the front end of the said trap part is located before the rear end of the toilet part, and the whole length of the western-style toilet main body is shortened.

Here, the front end of the trap part is a part which forms the flow water in the toilet part, and is the uppermost position of the inner bottom surface which forms the inverted U-shaped channel. The tip end of this trap part is determined as one point or a horizontal line by the cross-sectional shape orthogonal to the discharge direction of a trap part. In addition, the rear end of the toilet bowl part is the rearmost part in the opening to the upper part of the toilet part when it does not have a rim, and is the rearmost part in the boundary of the rim when it has a rim. The rear end of this toilet part is also determined as one point or a horizontal line.

In the western-style flush toilet of the seventh aspect of the invention, it is preferable that the rear wall of the trap portion is located before the rear end of the toilet portion. That is, as shown in FIG. 29, the conventional western flush toilet is necessarily located behind the rear wall 93e of the trap 95 at the rear end 93a of the toilet 93. As shown in FIG. For this reason, the total length of the western-style toilet main body 91 is inevitably lengthening. In contrast, in the western-style flush toilet of the seventh invention in which the rear wall of the trap portion is located before the rear end of the toilet portion, the overall length of the western-style toilet body is further shortened.

Usually, in the western flush toilet, a pair of toilet seat attachment holes for attaching a toilet seat, a toilet seat with a heating function, a toilet seat with a local cleaning function, etc. are formed behind the toilet bowl. In the western-style flush toilet of the 7th invention, it is also preferable that the front end of a trap part is located in front of each toilet seat attachment hole. That is, as shown in Fig. 29, the conventional western flush toilet is always positioned at the front end 95d of the trap section 95 behind the toilet seat attachment hole 96. For this reason, the total length of the western-style toilet main body 91 is inevitably lengthening. On the other hand, in the western-style flush toilet of the 7th invention in which the front end of a trap part is located in front of each toilet seat attachment hole, the total length of a western toilet main body is further shortened.

In the western-style flush toilet of the 7th invention, it is preferable that the downstream side bends forward rather than the front end of a trap part. If the total length of the western-style toilet main body is shortened, the base part which hides a trap part at least can also become small. In this way, when the pedestal portion is made small, the discharge port of the trap portion is likely to be close to the wall surface of the rear side in the pedestal portion, and there is a possibility that it cannot be properly connected to the drain socket. In this point, if the downstream side is bent forward from the front end of the trap part, even if the pedestal part is made smaller, the discharge port can be connected to the drain socket very well away from the wall surface of the rear side in the pedestal part.

As the washing apparatus, in addition to a conventionally known washing tank or the like, one that can be directly connected to a water supply pipe such as a water pipe for supplying washing water from the outside and capable of discharging the washing water by opening and closing the valve can be adopted. The effect of the seventh invention is great when the latter washing apparatus is employed. The former washing apparatus stores and discharges the washing water once, so that a considerable volume is required. For this reason, the effect of 7th invention will be reduced if the former washing | cleaning apparatus which requires considerable volume is employ | adopted, employing the western-style toilet main body which concerns on 7th invention in order to enlarge the narrow toilet. In view of this, if the latter cleaning device is employed, the effect of the seventh invention can be conspicuous because the conventional cleaning tank is not required, so that the narrow toilet can be enlarged.

{Eighth invention}

However, in the conventional Western-style flush toilet shown in FIG. 30, the miniaturization of the western-style toilet main body 91 is not examined, and it is easy to enlarge it as a whole. For this reason, in recent years, space saving is not aimed at, and the toilet which cannot secure a comparatively large space is further narrowed.

The eighth invention has been made in view of the above-mentioned conventional situation, and has an eighth problem to be solved by providing a Western-style flush toilet with miniaturization.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, earnestly examined and focused on the center of the inlet_port | entrance extended in the direction from a toilet bowl part to a trap part, and completed the 8th invention.

That is, the western-style flush toilet of the eighth invention includes a toilet bowl body and a western toilet bowl body having a trap part connected to the lower end of the toilet bowl, and washes the toilet bowl with washing water, and moves to the rear side according to the trap part. In the Western-style flush toilet for draining the washing water,

The center of the inlet extending in the horizontal direction of the trap part from the toilet part to the trap part is located before the center in the horizontal direction of the toilet part.

As shown in Fig. 30, the conventional Western-style flush toilet has a central toilet TO of the inlet TI extending in the horizontal direction of the trap section 95 from the toilet section 93 to the trap section 95. It is necessarily located behind the center BO in the horizontal direction of the section 93. For this reason, the total length of the western-style toilet main body 91 comprised by the toilet part 93 and the trap part 95 is necessarily lengthening in the front-back direction. On the other hand, in the western-style flush toilet of 8th invention, the center of the inlet of the said trap part is located before the center of the toilet part, and the whole length of a western-style toilet main body is shortened to front-back direction.

The inlet portion of the trap portion extends in the horizontal direction as a portion from the toilet portion to the trap portion. The part from the toilet part to a trap part is determined by the lower end of the rear wall of a toilet part. As shown in Fig. 21, the center TO of the inlet TI of the trap part is formed at each stage in the front-rear direction of the inlet TI because the inlet TI is formed symmetrically in the normal toilet bowl body. If TR, TF) is one point, it is the midpoint of the line segment TL connecting the rear end TR and the front end TF. In addition, as shown in FIG. 22, if at least 1 end of the front-back direction of the entrance TI is horizontal line TH, it is similarly determined by the midpoint THO of those or those horizontal lines TH.

In addition, as shown in Fig. 23, the center BO in the horizontal direction of the toilet bowl B has a lateral symmetry of the toilet bowl B since the toilet bowl B is formed symmetrically in an ordinary Western toilet main body. If each stage of is 1 point, it is determined by the water line assumed in the middle between the water line BR placed at the rear end and the water line BF placed at the front end. As shown in FIG. 24, if at least one end of the front-rear direction of the toilet bowl B is the horizontal line BH, it is determined similarly by the waterline BHO which sets it in the midpoint of that or those horizontal lines BH.

In the western-style flush toilet of 8th invention, it is preferable that the upstream side is formed by the rear wall of a toilet part rather than the front end of a trap part. If the upstream side is formed by a wall different from the rear wall of the toilet bowl, the wall has a thickness in the front-rear direction, and a gap having a thickness in the front-rear direction also occurs between the rear wall of the toilet bowl and the wall. By these dimensions, the entire length of the western-style toilet main body is lengthened in the front-rear direction. On the other hand, if the upstream side is formed by the rear wall of the toilet bowl, the dimension does not arise, and the entire length of the western-style toilet main body is shortened in the front-back direction.

Here, the front end of the trap part is a part which forms the flow water in the toilet part, and is the uppermost position of the inner bottom surface which forms the inverted U-shaped channel. The tip end of this trap part is determined as one point or a horizontal line by the cross-sectional shape orthogonal to the discharge direction of a trap part.

In the western-style flush toilet of the eighth aspect of the present invention, when the trap section has a cylindrical section whose inner surface is a cylindrical surface upstream from the front end, it is preferable that the axial line of the cylindrical section extends to 45 degrees or more in the horizontal direction. In this way, shortening in the front-back direction of the western-style toilet main body by a trap part can be realized, ensuring the water level of flowing water.

Moreover, in the western-style flush toilet of 8th invention, it is preferable that the downstream side bends forward rather than the front end of a trap part. If the overall length of the western-style toilet body is shortened, the pedestal portion at least concealing the trap portion can be made smaller. In this way, if the pedestal portion is made small, the discharge port of the trap portion is likely to be close to the wall surface of the rear side in the pedestal portion, and there is a possibility that it cannot be properly connected to the drain socket. In this point, when the downstream side is bent forward from the front end of the trap part, even if the pedestal part is made small, the discharge port can be connected to the drain socket properly from the wall surface of the rear side in the pedestal part.

As the washing apparatus, in addition to a conventionally known washing tank or the like, one that can be directly connected to a water supply pipe such as a water pipe for supplying washing water from the outside and capable of discharging the washing water by opening and closing the valve can be adopted. The effect of 8th invention is large when employing the latter washing | cleaning apparatus. The former washing | cleaning apparatus stores a washing water once and discharges, and a considerable volume is needed. For this reason, while employing the western-style toilet main body which concerns on 8th invention in order to enlarge the narrow toilet, if the former washing | cleaning apparatus which requires considerable volume is employ | adopted, the effect of 8th invention will be reduced. In view of this, if the latter cleaning device is employed, the effect of the eighth invention can be remarkable to achieve the enlargement of a narrow toilet because no conventional cleaning tank is required.

{Ninth invention}

However, in the above-mentioned conventional Western flush toilet, a siphon action is generated by the trap part while employing a cleaning tank such as a low tank for storing the washing water once, as a cleaning device, and thus the water saving effect was not sufficient.

That is, it is difficult for the washing tank to delicately adjust the amount of washing water discharged. For this reason, in the western-style flush toilet which employs a washing tank, it is easy to use a large amount of washing water as a result for sufficient discharge of wastewater.

Moreover, the edge part of the trap part which generate | occur | produces a siphon action is a part of the potty-type toilet bowl main body, and it is hard to be formed with high precision. For this reason, in this Western-style flush toilet, washing water must be used in large quantities so that the siphon action can be surely produced.

The ninth invention has been made in view of the above-described conventional situation, and has a ninth problem to be solved by providing a Western-style flush toilet capable of sufficiently discharging wastewater with a small amount of washing water.

The western-style flush toilet of the ninth invention includes a western-type toilet main body having a toilet section and a trap section connected to a lower end of the toilet section, and in the western flush toilet which washes the toilet section with washing water,

It is directly connected to the water pipe which supplies washing water from the outside, and is provided with the washing | cleaning apparatus which can discharge the said washing | cleaning water of water pressure by opening and closing of a valve, and the outlet of the said trap part is made of resin which has a hole which produces siphon action inside. Drain socket is provided, characterized in that the drain socket is connected to the drain pipe protruding from the floor surface.

In the western-style flush toilet of the ninth invention, since the washing apparatus is directly connected to the water pipe for supplying the washing water from the outside and can discharge the washing water at the water pressure by opening and closing the valve, a low tank or the like for storing the conventional washing water once Unlike the washing tank, the amount of washing water discharged by opening and closing the valve is easily controlled. For this reason, it is possible to discharge the minimum amount of the washing water that can sufficiently discharge the dirt in the Western flush toilet employing such a washing apparatus.

In addition, in the western-style flush toilet of the ninth invention, since the drain socket made of resin is employed, the hole can be formed with high precision and easily. For this reason, in the Western flush toilet employing a drain socket made of resin, even if a minimum amount of washing water is used, the siphon action can be surely produced.

{5th invention}

EMBODIMENT OF THE INVENTION Hereinafter, Embodiment 1, 2 which actualized 5th invention is demonstrated, referring drawings.

(Embodiment 1)

As shown in FIG. 10 and FIG. 11, the western-style flush toilet of Embodiment 1 is equipped with the western-style toilet main body 5 made of earthenware, and the washing | cleaning apparatus provided in this western-style toilet main body 5. As shown in FIG. In addition, the toilet seat and the toilet lid are not shown.

The western-style toilet main body 5 has a toilet part 1 which receives feces, an open rim 2 formed at the front circumference of the toilet part 1, and a trap part connected to the lower end of the toilet part 1. Have 3)

A washing tank (not shown), which is a part of the washing apparatus, is attached to the rear of the western-style toilet main body 5, and the washing tank is connected to a water pipe capable of supplying washing water by a pipe (not shown). The lower part of the washing | cleaning tank has the hose 8 extended to the right facing the western-style toilet main body 5 as another part of a washing | cleaning apparatus.

An end 6 protruding inward is formed at the boundary between the toilet 1 and the open rim 2, and a rim channel 4 is formed in the open rim 2 by the end 6. It is. The rim channel 4 is exposed to the toilet 1, and the washing water is passed through the opening 4a formed by the inner wall of the open rim 2 and the toilet 1. The tip of the hose 8 is located in the rim channel 4.

As shown in FIGS. 12-14, the upper surface of the edge part 6 is formed by the internal inclined surface 6a inclined inward and the external inclined surface 6b inclined outward. As shown in FIG. 10 and FIG. 12, on the upstream side of the washing water discharged from the hose 8, the inner inclined surface 6a is a small area and the outer inclined surface 6b is a large area. As shown in FIG.10 and FIG.13, when it goes to the downstream side of the wash water discharged | emitted from the hose 8, the inner inclined surface 6a and the outer inclined surface 6b become almost equal area. 10 and 14, the inner sloped surface 6a has a large area and the outer sloped surface 6b has a small area at a further downstream side of the washing water discharged from the hose 8. Only the inner side inclined surface 6a is formed in the most downstream side.

10 and 11, the western-style toilet main body 5 has an arc-shaped partition wall 7 that isolates the rim channel 4 from the rear side.

In the western flush toilet configured as described above, the washing water is discharged from the washing tank to the rim channel 4 through the hose 8 by the input of the washing switch of the user. At this time, since the hose 8 is provided only on the right side facing the western toilet body 5, the discharged washing water is gradually flowed down to the toilet bowl 1 while being guided to the right through the rim channel 4 to the toilet bowl. We turn inside part (1). And it is discharged | emitted via the trap part 3 with dirt.

Thus, in this Western-style flush toilet, since the hose 8 is provided only on one side, the washing water does not collide in the rim channel 4 or in front of the toilet bowl 1, so that strange sounds are not generated. Do not. Moreover, in this western flush toilet, since the open rim 2 exposes the rim channel 4 to the toilet part 1, mixing of the washing water and air does not occur at the start of washing, and the washing water is Since the shot is made via the opening 4a which is wider than the catching port of the closed rim, no strange sound is produced at this time. For this reason, quietness is excellent.

Moreover, in such a Western-style flush toilet, since the collision of the washing | cleaning water in the front of the toilet part 1 does not generate | occur | produce, there is no scattering of the washing | cleaning water and it does not wet the floor surface. For this reason, there is no discomfort to the user. Moreover, in this western flush toilet, the washing | cleaning ability of the toilet part 1 can be ensured by strengthening the force of washing water. In addition, since the washing water is discharged while turning the toilet bowl 1 in one direction (turning to one side), the waste water discharge performance is also excellent.

In particular, in this Western-style flush toilet, since the upper surface of the end 6 is formed as described above, the washing water discharged from the hose 8 flows to the toilet bowl 1 immediately upstream of the rim channel 4. Since it is guided to the most downstream side and flows down into the toilet bowl part 1, washing | cleaning in the toilet bowl part 1 can fully be performed. Moreover, by this, the washing water is easily turned in the toilet bowl 1, and the discharge performance of the dirt can be improved. In addition, since the washing water is guided only to the toilet part 1 on the downstream side, the washing water is not circulated again or left in the rim water passage 4, so that the washing water is unnecessary and the water saving effect is high. .

In addition, in this Western-style flush toilet, since the western-style toilet main body 5 has the partition 7, there is no guiding the washing water to the rear side, so there is no wasteful use of the washing water and the water saving effect is high.

In addition, in this Western-style flush toilet, since there is no water catcher, the structure of the open rim 2 becomes simple, the number of manufacturing processes is small, and also the manufacturing cost can be reduced.
