The conventional configuration described above requires separate heaters for heating the toilet seat and heating the flushing water, and also includes a hot water storage tank to stabilize the heating temperature of the flushing water. This has the disadvantage that the toilet bowl itself becomes larger. Another problem is that if the cleaning water stored in the hot water storage tank is left unused for a long time at an appropriate temperature, bacteria will grow and the water will become unsuitable for cleaning.

The present invention solves the above-mentioned conventional drawbacks by providing a water passage inside the toilet seat and using the interior of the toilet seat as a hot water tank for washing water.

Hereinafter, the present invention will be explained based on FIGS. 2 to 6 showing one embodiment thereof.

FIG. 2 shows a configuration diagram showing the heating state of the toilet seat in an embodiment of the flush toilet seat of the present invention. Items with the same numbers as in FIG. Only the points that are different from Figure 1 will be explained. Reference numeral 29 denotes a water passage provided in the toilet seat 1, and this water passage 29 serves as a hot water storage tank for washing water and also serves as a heater for the toilet seat 1. 30 is an inlet of the water passage 29, and 31 is an outlet of the water passage 29. 32 is a heater that heats the wash water flowing between the pump and the water passage inlet 29 of the toilet seat 1; 33 is a heat exchanger that transfers the heat of the heater 32 to the wash water; this heat exchanger 33 is a small instant heater; It's getting old. 34 connects the cleaning water supply channel to the inlet 7 of the pump 6.
Alternatively, it is a three-way valve that switches to the cleaning nozzle 17 via the hose 35. 36 is the three-way valve 34
A hose 37 connects the heat exchanger 33 and the inlet 30 of the water passage 29 of the toilet seat 1.

In the above configuration, the cleaning water is not discharged from the cleaning nozzle 17, but by the action of the three-way valve 34, the water is discharged from the outlet 8 of the pump 6 → the hose 10 → the heat exchanger 33 → the hose 37 → the inlet 30 of the water passage 29 of the toilet seat 1. →Toilet seat 1
Water passage 29 → Outlet 31 of water passage 29 of toilet seat 1 →
It circulates in the order of hose 36 → three-way valve 34 → inlet 7 of pump 6, and as a result, hot water at an appropriate temperature for cleaning is stored in the water passage 29 inside the toilet seat 1 while being heated and controlled by the heater 32, and the stored hot water is Toilet seat 1 is heated by.

FIG. 3 shows a configuration diagram showing the cleaning and heating states of the toilet seat in the above embodiment of the flush toilet seat of the present invention. At this time, the flush water supply channel is controlled by the switching operation of the three-way valve 34. Water tank 3 → hose 5 → inlet 7 of pump 6 → outlet 8 of pump 6 → hose 10 → heat exchanger 33 → hose 37 → inlet 30 of water passage 29 of toilet seat 1 → water passage 29 of toilet seat 1 → water passage 29 of toilet seat 1 The outlet 31 of the water passage 29 → the hose 36 → the three-way valve 34 → the hose 35 → the cleaning nozzle 17 are formed in this order, and the toilet seat 1 is heated while being cleaned.

In the above configuration, since the toilet seat 1 is used as a hot water storage tank for flushing water, a separate hot water storage tank is not required.As a result, it can be made smaller, and a large amount of hot water can be stored, providing stable flushing hot water. Provides warmth. Further, since the toilet seat 1 can be automatically heated by storing hot water in the toilet seat 1, it has the advantage that a toilet seat heater and a function to control it are not required.

FIG. 4 shows a configuration diagram of another embodiment of the cleansing toilet seat of the present invention, in which 38 is the toilet bowl body, 3
9 is a toilet seat lid, 40 is a heavy peg, and this heavy peg 40 is a stick 4
1 to the toilet seat 1. In the configuration shown in FIG. 4, since hot water is stored in the water passage 29 inside the toilet seat 1, raising and lowering the toilet seat 1 becomes difficult, but the weight is balanced by the heavy stud 40, making raising and lowering easier. It is something that exists.

FIG. 5 shows a configuration diagram of another embodiment of the toilet seat according to the present invention when the toilet seat is not heated, and FIG. 6 shows a configuration diagram when the toilet seat is heated in the above embodiment. 4
A heat insulating sheet 2 is provided on the human body contact side of the toilet seat 1 and covers the toilet seat 1, and this heat insulating sheet 42 is provided between the toilet seat 1 and the toilet seat lid 39. 43 is a hook provided on the heat insulating sheet 42;
is a hook provided on the toilet seat 1. With this configuration, especially in the summer, when it is preferable that the temperature of the stored hot water inside the toilet seat 1 is not transmitted to the human body, the heat insulation sheet 42 can block the conduction of the heat, so that it can be used comfortably even in the summer. In addition, since the heat insulating sheet 42 can suppress the heat dissipation of the water stored in the toilet seat 1, it also has the advantage of being useful for energy saving.

In addition, in the winter when it is desired to heat the toilet seat 1, as shown in FIG.
By hanging the button on the hook 45 of the toilet seat lid 39, the human body can be brought into direct contact with the toilet seat 1.
As a result, heating can be performed.

In the above configuration, the heat insulating sheet 42 can be attached to and detached from the toilet seat 1 side or the toilet seat lid 39 side, so it can be used in the same way as conventional usage, and the toilet seat heating in summer and winter can be done without any inconvenience. You can switch.

As described above, the cleansing toilet seat of the present invention includes a toilet seat having a water passage inside, a cleaning nozzle that discharges washing water to the washing part of a human body sitting on the toilet seat, and a washing nozzle that sucks water from a water tank and has a water passage through the toilet seat. A pump that supplies water to the waterway inlet, a three-way valve that is connected to the toilet seat waterway outlet and switches the water supply to the cleaning nozzle or pump inlet, a heater that heats the water that flows between the pump and the toilet seat waterway inlet, and the toilet seat. When not flushing, a water pump heated to an appropriate temperature circulates the water passage inside the seat to heat the seat, and when flushing, water is drawn from the water tank. The system inhales hot water, heats it to an appropriate temperature with a heater, and supplies it to the passageway inside the toilet seat to heat the toilet seat. At the same time, the hot water coming out of the passageway inside the toilet seat is sent to the cleaning nozzle and discharged to perform cleaning. It has the following features.

A problem specific to flushing toilet seats is ensuring the cleanliness of the flushing water. Washing with water that is contaminated with germs can cause illness, so it is necessary to use fresh water for washing, but with conventional hot water storage tanks, if you do not wash for a long time, the washing water will run out. Since the hot water remains in the tank at an appropriate temperature, it is convenient for bacteria to grow, and there is a problem when cleaning it at intervals. However, with the configuration of the present invention, the wash water is appropriately heated by the heater and circulated through the passage inside the toilet seat in order to heat the toilet seat even when the toilet is not washed for a long time, so the proliferation of bacteria is suppressed more than in a stagnant state. Moreover, in order to heat the toilet seat, the cleaning water is heated more frequently by the heater, and the number of germs that come into contact with the heated heater is much more likely to be killed, which expands the ability of the cleaning water to maintain cleanliness. It is.

In toilets that heat the toilet seat by storing hot water inside the seat, the toilet seat is flat and has a large surface area, which causes temperature unevenness due to natural heat radiation. Due to convection, the front end of the toilet seat tends to get hot and the rear end tends to get warm, both of which lead to discomfort when sitting. However, with the configuration of the present invention, the flush water inside the toilet seat is circulated by the pump, so no matter what shape the toilet seat is in or even when the toilet seat is upright, the temperature of the toilet seat is uniform and comfortable. You can get a warm feeling.

Since the toilet seat can be used as a hot water storage tank for washing water, there is no need for a separate hot water storage tank, making it possible to downsize the system and store a relatively large amount of hot water, ensuring a stable temperature even during long periods of washing.

A dedicated heater and control function for the toilet seat are no longer required, simplifying the structure.

In addition, by providing a weight balancer on the toilet seat, it becomes easier to raise and lower the toilet seat.Also, a heat insulating sheet is provided on the toilet seat, and this heat insulating sheet is provided between the toilet seat and the toilet seat lid, and the seat is attached to the valve seat or the toilet seat lid. By making it removable, the heat insulating sheet can block the conduction of the heat when you do not want the temperature of the stored hot water inside the toilet seat to be transmitted to your body, such as in the summer, so it can be used comfortably even in the summer. At the same time, it has features such as being useful for energy saving as it can suppress the dissipation of heat from the water stored in the toilet seat.Furthermore, by attaching the heat insulating sheet to the toilet seat side or the toilet seat lid side in summer and winter, It can be used in the same way as before.
