A shaft is installed inside the chute, and a bearing cylinder in which a straight pipe part having a nozzle for cleaning the buttocks leading to the hot water supply pipe is slidably inserted on one side is fixed, and the straight pipe is inserted into the guide groove of the bearing cylinder. A chair-shaped toilet seat body with a lever integrated with the part interposed by a bullet, a suction pipe of a pump body that connects to the hot water supply pipe and supplies hot water by operation of the pump, and a submersible heater are inserted into the hot water storage tank. , a hot water storage tank having a check valve unit provided at the lower part of the water storage tank to open and close a valve port communicating with the water tank of the water storage tank, and a hot water storage tank having a heat insulating layer applied to the surface and housed in the water tank. .

(Function) After using the toilet, pull the lever toward the toilet seat body so that the nozzle of the hot water supply pipe faces below the buttocks, and then operate the pump to compress or release it. Then, hot water that has been brought to an appropriate temperature in a hot water storage tank is pumped up and sprayed onto the buttocks through a hot water supply pipe and nozzle to cleanse the body.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

As shown in Figures 1 to 4, the hot water storage tank 1
The hot water storage tank 1 is of a submerged type whose surface is covered with a heat insulating layer 2, and this hot water storage tank 1 is housed on one side of the water tank C of the water storage tank B installed in advance in the flush toilet A. The water storage tank B has its base end connected to the pump body 4 through an insertion hole 3 for piping provided in advance in the water storage tank B and an insertion hole 3a common to the insertion hole 3, and its tip connected to the hot water storage tank B. Tank 1 hot water tank 5
A suction pipe 6 facing the water tank B is inserted through the suction pipe 6 and fixed to the threaded portion 7 of the suction pipe 6 from the inside of the hot water storage tank 5 and the outside of the water storage tank B using nuts 8, 8. The check valve unit 9 has an annular body 10 attached to an insertion hole 3b formed in the lower part of the hot water storage tank 1 and inserted through the water tank C and the hot water storage tank 5, and a valve communicating with the valve port 11 of the annular body 10. A check valve 13 of Utility Model Publication No. 1326/1982 and a tubular spacer 14 for fixing the check valve 13 within the valve chamber 12 are interposed in the chamber 12, and the spacer 14 is secured with a packing 15 and a cap nut 16. Due to the watertight connection, when the water level of the hot water in the hot water tank 5 falls below the water level in the water tank C, the check valve 13 opens the valve port 11 and introduces the water in the water tank C into the lower part of the hot water tank 5. The hot water storage tank 5 and the water tank C are kept at the same water level, and when the water level of the water tank C is used for flushing the toilet bowl D and the water level decreases, the valve port 11 is closed so that hot water does not flow into the water tank C. do.
The hot water supply pipe 17 whose base end is connected to the pump body 4 is
Straight pipe part 1 slidably inserted into toilet seat body 18 described later
7a to communicate with the nozzle 19 at the tip so as to spout hot water, and this straight pipe portion 17a is
The straight pipe portion 1 is slidably inserted into insertion holes 3c and 3d of a bearing cylinder 20 fixed to one side of the toilet seat body 18 and a large insertion hole 3e of a chute 21 to be described later.
A lever 23 is provided on the boss 22 which is fitted onto the shaft 7a and fixed at a fixed position, and the lever 23 projects outward from a guide groove 24 opened in the bearing sleeve 20. A locking groove 24a provided perpendicularly to the outer end of the bearing sleeve 20 is set in a fixed position, and the straight pipe portion 17a is wound between the boss 22 and the inner wall of the bearing sleeve 20, and the straight pipe portion 17a is always positioned in the direction indicated by the arrow. A coil spring 25 is interposed that is elastically loaded in the P direction. The toilet seat body 18 is hollow and has a generally oval or elliptical shape in plan view with a wide bottom, and has an annular locking edge 26 at the upper part of the hollow inner wall, and the locking edge 26 has a bottomless approximately The chute 21 has a horse-shaped hole shape and is supported in a detachable manner on a flange portion 27 provided on the upper periphery of the chute 21.
are stacked so that they can be raised and lowered freely, and the chute 21
A downwardly tapered outlet 29 is inserted into the inside of the toilet seat D for a required length. The submersible heater 30 is
It is inserted into the hot water storage tank 5 from the upper part of the hot water storage tank 1, and is provided so that the hot water in the hot water storage tank 5 can be maintained at a preset temperature. FIG. 5 shows another embodiment in which the pump 32a is of a foot-operated type instead of the hand-operated pump 32 of FIG. Now, in order to wash your buttocks after using the toilet seat body 18 shown in FIG. Due to the elastic action of the coil spring 25 between the inner walls of the bearing sleeve 20, the straight pipe portion 17a moves instantaneously together with the lever 23 in the direction of arrow P, moving the nozzle 19 directly below the butt as shown by the chain line in FIG. 3A. Displace it as shown and stop. Next, when you put your hand on the pump 32 and operate it in the grip direction, the hot water that has been heated to an appropriate temperature by the submersible heater 30 in the hot water storage tank 5 passes through the suction pipe 6 of the pump body 4 and flows into the hot water supply pipe 17. The water is then sprayed from the nozzle 19 through the straight pipe portion 17a, and finishes washing the buttocks thoroughly. At this time, the pump 32 only needs to be operated two to three times, and the strength of the gripping pressure can be adjusted as necessary. When cleaning is completed, the lever 23 is operated in the opposite direction to return the lever 23 to the locking groove 24a.

When the hot water in the hot water tank 5 decreases due to the above-mentioned cleaning, a water level difference occurs between the water level in the hot water tank 5 and the water level in the water tank C of the water storage tank B, so water pressure due to the water level difference is applied to the check valve 13. Water is added from the mouth 11 side to open the valve, and water is supplied until the water level in the hot water tank 5 becomes the same as that in the water tank C. Other embodiments also operate in the same manner as described above.

(1) In addition to providing a heat insulating layer on the surface of the water storage tank, the water storage tank is equipped with a submersible heater, a suction pipe leading to the pump body, and a check valve unit that opens and closes the valve port leading to the water tank. The nozzle of the hot water pipe that communicates with the body is freely inserted into the body of the seat-type toilet seat, so the simple mechanism and easy operation ensure that the buttocks of elderly people and young children are washed cleanly when they use the toilet. can do.

(2) A check valve unit with a check valve that opens and closes on the hot water tank side is installed at the valve port of the hot water storage tank, so that when the water level in the hot water tank drops, water is automatically supplied from the water tank of the water storage tank. Not only can you
When the water level in the water tank drops (due to the release of wash water), the valve is closed, so hot water in the tank is not wasted.

(3) Since the surface of the hot water storage tank is covered with a heat insulating layer, heat radiation can be kept to a minimum even when submerged in water, and heat loss can be minimized to maintain the water temperature at a level suitable for washing one's buttocks. It can be done slightly.

(4) Compared to conventional toilets, a seat-shaped toilet seat body is equipped with a hot water supply pipe that can be freely discharged, and the hot water supply pipe is combined with a hot water storage tank having a pump body, submersible heater, and suction pipe. It is extremely convenient because it can be supplied at low cost and can be used as is in existing flush toilets.
