Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for promptly discharging water such as dew condensation water from the storage chamber of a cleaning device to the outside in a local cleaning toilet.

[Conventional technology and its problems]

FIGS. 3 (a) and 3 (b) are a front sectional view and a side sectional view showing a conventional local cleaning toilet B having a local cleaning device built therein. As shown in the drawing, a storage chamber 7 is provided in the rear portion of the toilet body 1, and in the storage chamber 7, a water storage tank 3, a warm air fan 4, an odor suction fan 5, a cleaning nozzle 6, a hot water tank 1 are provided.
A local cleaning device including a water supply pump 12, a control device such as a temperature control thermostat, and other accessory devices is housed.

By the way, in the above-mentioned conventional local cleaning toilet B, there is a problem that water stays in the bottom portion 70 of the storage chamber 7.

Normally, flush toilets use a large amount of flush water,
Further, as shown in FIG. 3 (b), since the water reservoir 9 is often provided in the toilet bowl 2, the toilet bowl B is placed in a humid environment. Therefore, the inside of the storage chamber 7 becomes a humid atmosphere due to the inflow of air containing moisture, and dew condensation is extremely easily caused even by a slight temperature decrease. This condensed water is mentioned as one of the causes of the accumulated water in the storage chamber 7. In addition, cleaning water, urine droplets, and the like may enter through a slight gap in the attachment portion 60 of the cleaning nozzle 6 to the toilet bowl 2, which also causes accumulated water in the storage chamber 7. . Furthermore, the piping of the cleaning device (for example, the connection hose 16 between the hot water tank 11 and the water supply pump 12)
If a water leak occurs in the storage room, this is also the bottom 7 of the storage room.
This contributes to the retention of water at 0.

The accumulation of water in the storage chamber 7 causes the development of mold and the propagation of various bacteria, which is not hygienic. Not only that, it may cause a short circuit in the electric circuit, resulting in an accident due to a failure or malfunction of the device. Thus, the accumulated water adversely affects the local flush toilet both in terms of function and hygiene.

[Means for solving problems]

The present invention is a drainage structure for a storage room, which was devised to solve the above-mentioned problems, and is characterized in that a local cleaning device is built in a bottomed storage room provided at the rear of the toilet body. In the flush toilet, a drainage port is formed in the lowest part of the storage chamber, the drainage port and the toilet bowl discharge part are connected by a water supply passage, and the drainage port is further provided with an odor preventing seal mechanism.

[Action]

By forming a drainage port in the lowest part of the storage room and connecting the drainage port and the toilet discharge part by a water supply path, the dew condensation water generated in the storage room, the infiltrated cleaning water or the spray of urine, and the cleaning device Water leaked from the pipes will be immediately discharged to the outside and removed. Therefore, since water is not retained in the storage chamber, the generation of mold and the propagation of various bacteria are prevented, and the electric circuit is not short-circuited. In addition, by providing an odor prevention seal mechanism at the drain outlet, it is possible to prevent contaminated air, gas, odors, etc. from flowing back to the storage chamber from the toilet discharge portion, and the toilet discharge portion is clogged due to an accident and sewage It is possible to prevent sewage from entering the storage chamber when the water flows back.

〔Example〕

 Hereinafter, details of the present invention will be described with reference to the drawings.

The same reference numerals as those in FIG. 3 showing a conventional example represent common members.

FIG. 1 is a side sectional view showing an embodiment of a local flush toilet A according to the present invention. As shown in the figure, a bottomed storage chamber 7 is provided at the rear of the toilet body 1, and a drain port 13 is formed at the lowest portion of the bottom 70 of the storage chamber 7.
3 and the toilet discharge part 15 are connected by the water supply path 14. The water supply passage 14 is formed integrally with the toilet body 1 on the back surface side of the toilet bowl 2 in the water reservoir 9.

An odor prevention seal mechanism 8 is attached to the drain port 13 formed at the upper end of the water supply passage 14. This is the second
It is shown enlarged in the figure. The odor preventing seal mechanism 8 has both a trap function and a check valve function, and includes a trap body 30 attached to the drain port 13, a cap 32 installed in the trap body 30, and a trap body. The lid 21 is attached to the upper opening 24 of the cover 30.
The trap body 30 is a cylindrical body in which the flange portion 20 is formed on the upper portion of the outer peripheral surface, and the flange portion 20 is attached to the locking step portion 40 of the drainage port 13. A standing portion 35 is provided around the opening 34 at the center of the lower end surface. The cap 32 has a bell shape made of a material lighter than water. This is capped on the upright portion 35 so as to cover the upper end opening 36 thereof, and water is stored in the annular groove between the inner peripheral surface 31 of the trap body 30 and the upright portion 35. 33 is formed. The floating position of the cap 32 is regulated by the lid 21 attached to the upper opening 36 of the trap body 30. A water passage hole 22 for drainage is formed in the center of the lid body 21. In addition, the water passage hole 22
If the recess 23 is provided around, the introduction of water from the storage chamber bottom 70 into the trap body 30 is promoted.

Condensation water or the like on the bottom 70 of the storage chamber is used for the water passage 2 of the lid 21.
2 flows into the trap body 30. Since the cap 32 is lighter than water, the cap 32 floats by the inflowing water and causes the inflowing water to flow out from the upper end opening 36 of the standing portion 35 to the water supply passage 14. Further, when sewage flows back through the water supply passage 14 due to an accident or the like, the cap 32 floats up, and the rubber material 37 provided on the head portion closes the water passage hole 22 of the lid body 21. This prevents infiltration of dirty water into the storage chamber 7.

The height position of the drain port 13 of the bottom 70 of the storage chamber is preferably higher than the water level 10 of the toilet bowl 2. When sewage flows backward due to an accident, the rising speed of the water level becomes slightly slower when it exceeds the water surface 10. Therefore, if the position of the drain port 13 is set higher than the reservoir surface 10, it is possible to prevent or delay the sewage from reaching the drain port 13.

The embodiments of the present invention are not limited to those described above. For example,
Although illustration is omitted, if the storage chamber bottom portion 70 is inclined downward toward the drainage port 13, drainage can be further improved. It is needless to say that the odor preventing seal mechanism used in the present invention may have a structure other than the belt wrap shown in the second illustration. As described above, the present invention can be appropriately modified according to the embodiment.

[Effect of device]

As is clear from the above description, according to the drainage structure of the storage chamber according to the present invention, the dew condensation water, the infiltration water, etc. are not quickly discharged and removed and accumulated, so that the cleaning device built in the storage chamber is provided. It does not cause a failure such as a short circuit in the electric circuit, and suppresses the growth of mold and germs in the storage room.

In essence, the present invention provides a local toilet bowl that is both functionally and hygienically excellent.
