The water in the hot water storage chamber 17 is heated by energizing the heater 28, and the heated hot water reaches the hot water supply chamber 18 through the water passage 22 between the barrier plate 21 and the cover 25, and the hot water supply chamber 1
Cold water in the lower part of 8 flows into the hot water storage chamber 17 through the water passage holes 23 of the dam plate 21 and is heated. In this way, the water in the tank body 16 circulates, is controlled by the output signal of the temperature sensor 30, and reaches a substantially predetermined temperature (for example, 42
℃) is maintained.

During this time, air bubbles are generated around the heater 28. The air bubbles move up in the hot water storage chamber 17 and then move toward the hot water supply chamber 18 along the lower surface of the cover 25 to form the connection port 3
2 to the projecting portion 41 of the sub tank 40 through the air vent pipe 46, and is discharged to the outside from the overflow pipe 98. In addition, dew condensation may occur on the outer surface of the sub-tank due to a rise in the water temperature in the hot water storage tank 15 or a rise in the room temperature. This dew condensation collects on the tray 35 and collects on the front side. After that, it is drained to the drain pool 7 and evaporated. Therefore, rust does not occur in the electric parts inside the cleaner main body 1 and the power supply board 48 and the operation board 49 are not short-circuited.

When the urination is over, the user pushes the bottom button 51 of the operation panel 50 in the same state. As a result, the water supply pump 60a is energized to operate and the hot water in the hot water storage tank 15 is discharged from the suction port 20a to the pressure valve 6a.
2a and the switching valve 64 to supply to the buttocks nozzle 77a. At this time, the switching valve 64 is the bottom nozzle 77.
It is assumed that it has been switched to the a side. Butt nozzle 7
When hot water is supplied to 7a, the bottom pressure nozzle 77a descends from the nozzle guide 76a due to the water pressure, and hot water is jetted from the nozzle holes to wash the buttocks. When the washing is finished, if the stop button 53 of the operation panel 50 is pressed, the water supply pump 60a is stopped, the jet of hot water from the buttocks nozzle 77a is stopped, and the buttocks nozzle 77a rises and returns to the original state. .

During this period, the water in the hot water storage tank 15 decreases, but since the water is continuously supplied from the sub tank 40 communicating with the hot water storage tank 15, the water level in the sub tank 40 decreases, but the hot water storage tank 15 is always full. The heater 28 is heated to maintain a predetermined temperature. Finally, when water is made to flow from the flush water tank 104 to the toilet body 101, a part of the water is supplied to the sub tank 40 as described above, and the sub tank 4
When 0 is full, the water is drained from the overflow pipe 98 into the wash water tank 104. When a large amount of hot water is used and the water in the sub-tank 40 runs out and the hot water level in the hot water storage tank 15 drops, the float switch 31 descends, and when the lower limit position is reached, the water supply pumps 60a, 60b cannot be energized. To

When the bidet nozzle 77b is used, the bidet button 52 on the operation panel 50 is pressed to activate the second water supply pump 60b, and the washing can be performed by the same operation as described above. In addition, when it is desired to change the water force of the hot water ejected from the posterior nozzle 77a and the bidet nozzle 77b, the water force button 54 of the operation panel 50 may be pressed to adjust. When the temperature of the hot water is desired to be changed, the water temperature button Adjust by pressing 55. Further, when the deodorant is contained in the balancer 86, the deodorant is released by pressing the deodorant button 56 on the operation panel 50.

When a man stands up and uses it, the front panel 73 of the nozzle accommodating chamber 72 of the nozzle unit 70 is easily soiled. In this case, the clean button 57 on the operation panel 50 is pushed after use. As a result, the switching valve 64 switches the posterior nozzle 77a to the clean nozzle 74, and the water supply pump 60a operates to allow hot water to flow from the nozzle hole 75 of the clean nozzle 74 along the front panel 73 as shown in FIG. Nozzle accommodating chamber 7 spouting in all directions
The front panel 73 of No. 2 and its vicinity are washed. At this time, since the side edges 73a and 73b of the front panel 73 are provided with roundness, the viscosity of the hot water prevents the hot water from flowing along the roundness as shown in FIG. 18 and scattering around.

When the cleaning is finished, the clean button 5 is pressed again.
When 7 is pressed, the water supply pump 60a is stopped and the switching valve 64 is switched to the posterior nozzle 77a side. In this case, since the lower portion of the front side of the body 1 is formed in a concave shape as described above and is located rearward of the upper portion, the front side of the body 1 is not obstructed when standing in front of the toilet body 101. It is possible to move forward without moving, and therefore the front side of the toilet body 1 or the floor surface is not polluted.

Further, even when the nozzle unit 70 is removed from the toilet body 101 and placed on the floor of the toilet when cleaning the toilet body 101, the pressure valves 62a, 62b are used.
Since the flow of hot water is blocked by the hot water, the hot water does not leak from each nozzle attached to the nozzle unit 70.

In the above description, the hot water cleaning device according to the present invention is installed in an existing toilet, but it goes without saying that it can be installed in a new toilet. Further, although the case where the attachment portion 65 of the cleaner main body 1 and the connecting portion 82 of the nozzle unit 70 are configured as shown is shown, the present invention is not limited to this, and the attachment / detachment is easy, and the top / bottom Alternatively, another structure may be used as long as the nozzle unit 70 separates from the cleaner body 1 when a predetermined load acts in the left-right direction, the rearward direction, or the twist.

In the above embodiment, the pressure valves 62a and 62b are used as valve bodies provided in the flow passage between the discharge port of the water supply pump and the nozzle. However, the present invention is not limited to this, and an electromagnetic valve may be used as the valve element. In this case, both water supply pumps 60a, 60
It may be configured to open and close in conjunction with the operation of b.

Further, in the above description of the embodiment, the height of the ceiling surface of the hot water storage tank 15 and the height position of each nozzle when the nozzle unit 70 is installed in the toilet body 101 (hereinafter, simply referred to as "nozzle height position"). )) Was not specified. However, if the height of the ceiling surface of the hot water storage tank 15 is set higher than the height position of the nozzles, and if the pressure valves 62a and 62b are damaged, the water in the hot water storage tank 15 has a height of the water surface that is higher than that of the nozzles. It leaks from the nozzle until it reaches the height position. Then, it is conceivable that the suction ports 20a, 20b of the water supply pumps 60a, 60b are exposed on the water surface and air enters the water supply pumps 60a, 60b. Therefore, the hot water storage tank 15
It is conceivable that the height of the ceiling surface of is approximately the same as the height of the nozzle. By doing so, even if the pressure valves 62a and 62b are damaged, hot water leaks from the nozzles and the suction ports 2 of the water supply pumps 60a and 60b are leaked.
0a and 20b are not exposed on the water surface, and air does not enter the water supply pumps 60a and 60b.

[0055]

As is apparent from the above description, according to the present invention, the following effects can be obtained.

A valve body is provided in the flow passage between the discharge port and the nozzle of the water supply pump, the flow passage being opened when the water supply pump is in operation and closed when the water supply pump is stopped. Therefore, hot water does not leak from the nozzle when the water supply pump is stopped.

Further, since the pressure valve is used as the valve element, it is possible to prevent hot water leakage from the nozzle with a simple structure. Furthermore, since the pressure valve was set to open the flow path when a pressure larger than the pressure between the water inlet and the floor where the toilet body was installed was applied, it goes without saying that with the nozzle unit installed, Even when the nozzle unit is removed from the toilet body and placed on the floor of the toilet, hot water does not leak from the nozzle attached to the nozzle unit. Therefore, the nozzle unit can be placed on the floor of the toilet, which is convenient for cleaning, for example.

Further, since the position of the ceiling surface of the hot water storage tank and the position of the nozzle when the nozzle unit is placed on the toilet body are set to substantially the same height, even if the valve body is damaged Even if it is, hot water does not leak from the nozzle and the suction port of the water supply pump is not exposed from the water surface,
No air gets into the water pump.
