Then, as shown in FIG. 1, the nozzle unit 70 is set on the rearmost portion of the toilet body 101, and the toilet seat 102 is closed. At this time, the nozzle accommodating chamber 72 is located in the rear part of the toilet body 1 in the substantially central portion in the left-right direction, and the balancer 86 is on the opposite side of the cleaning device body 1 from the toilet body 1
It is located below the upper end surface of 01 to keep the left and right balance.

Next, the water supply pipe 97 is connected to the connection ports 43 and 44 of the sub tank 41 protruding from the cover 4 of the cleaner main body 1.
Also, one end of the overflow pipe 98 is connected, and the other end of the water supply pipe 97 is connected to the branch port 93 of the distributor 90 attached to the faucet 105. At this time, the other end of the overflow pipe 98 integrated with the water supply pipe 97 is connected to the distributor 9
It opens in the vicinity of the main water supply port 92 of 0. This completes the installation of the warm water washing device. In addition, in the figure, the cleaner body 1
Although the case is shown in which it is installed on the left side of the toilet body 101, it can also be installed on the right side. In this case, the cleaner body 1
The mounting portion 65 and the connecting portion 82 of the nozzle unit 70 provided on the side opposite to the drawing may be used. Furthermore, the mounting portions 65 may be provided on the left and right side walls of the cleaner body 1 as required.

In the hot water cleaning apparatus installed as described above, the hot water storage tank 15, the water supply pumps 60a and 60b, and the sub tank 40 are arranged in a well-balanced manner in the cleaner body 1, and the nozzle unit 70 is cleaned. It is attached to a substantially central portion of the container body 1 in the front-rear direction. Since the balancer 86 is provided at the other end of the nozzle unit 70, and the balancer 86 is located below the upper end surface of the toilet body 101, the balance is extremely good as a whole, and the cleaner body 1 There is no danger of falling.

In this state, the valve 106 is opened to supply water to the wash water tank 104. At this time, the water discharged from the faucet 105 is supplied from the main water supply port 92 to the wash water tank 104, and a part of the water is diverted by the weir 94 to change the direction.
From the water supply pipe 97 through the sub tank 40, the water supply port 42, the connection port 26, and the water supply pipe 27.
5 is supplied. Then, when the hot water storage tank 15 is full, the sub tank 40 is continuously supplied with water, and when the sub tank 40 is full, the overflowed water is discharged to the wash water tank 104 from the opening through the overflow port 44 and the overflow pipe 98. As a result, the amount of water supplied from the main water supply port 92 of the distributor 90 to the wash water tank 104, and thus the amount of water for hand washing, increases, and the overflow pipe 98 flows into the water flow from the main water supply port 92 of the distributor 90. It can be seen that the shape of the flowing water changes due to the addition of drainage from the sub-tank 40 and overflows from the sub-tank 40. At this time, even if the sub tank 40 is full of water,
Since the sub tank 40 is provided in the cleaner main body 1, no load is applied to the wash water tank 104.

When the hot water storage tank 15 and the sub tank 40 are completely supplied with water, the plug of the power cord 99 (FIG. 2) is inserted into the outlet to supply power to the power supply board 48 and the operation board 49. The heater 28 is energized via the. At this time, the float switch 32 is at the upper limit position, and both the power feeding pumps 60a and 60b are in an operable state. 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.

As described above, since the sub-tank 40 is formed in a substantially L-shape and the projecting portion 41 is provided on the rear side, the capacity of the sub-tank 40 can be increased. In addition, since the connection port 43 of the water supply pipe 97, the connection port 44 of the overflow pipe 98, and the connection port 45 of the air vent pipe 46 are collectively provided on the projecting portion 41, handling is convenient.

Further, the sub-tank 40 is installed above the hot water storage tank 15, and a printed circuit board in which electric parts such as a power supply board 48 and an operation board 49 are mounted in a space formed between the sub-tank 40 and the cover 4. Since 47 is provided, the space can be effectively used and the hot water storage tank 15
Since the heat of is blocked by the sub-tank 40 containing water, the printed circuit board 47 and the electric parts mounted thereon are not affected by the heat. Further, since the printed circuit board 47 is disposed at the uppermost part in the cleaner main body 1, even if water leaks to the sub tank 40, the hot water storage tank 15, etc., the printed circuit board 47 and the electrical equipment mounted on the printed circuit board 47. There is no risk of water splashing on parts. Therefore, there is no possibility that the characteristics of the printed circuit board 47 or the electric components mounted on the printed circuit board 47 may change, contact failure due to rust may occur, or the circuit pattern may be short-circuited.

Also, 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 along the lower surface of the cover 25 toward the hot water supply chamber 18 which is a high place to remove air. The air passes from the hole 31 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. At this time, cover 2
Since 5 has a high front side, the ascended bubbles move to the front side along the lower surface of the cover 25, and a large amount of bubbles can be efficiently discharged from the air vent hole 31 provided at the highest position. . Therefore, bubbles do not enter the water supply pumps 60a and 60b to cause trouble. Further, when a large amount of bubbles move, they collide with the float switch 32 provided in the vicinity of the air vent hole 31 and generate minute vibrations, so that the float switch 32 does not cause a physical malfunction. 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 32 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 storage chamber 7
The front panel 73 of No. 2 and its vicinity are washed. When the cleaning is finished, by pressing the clean button 57 again, the water supply pump 60a is stopped and the switching valve 64 is switched to the posterior nozzle 77a side. In addition, in this case, since the lower portion of the front side of the toilet body 1 is formed in a concave shape as described above and is located rearward of the upper portion, the toilet body 101
It is possible to stand forward and move forward without obstructing the toes, and therefore the front side of the toilet body 1 and the floor surface are not soiled.

As described above, the present invention is provided with the water supply pump for supplying water to the posterior nozzle and the water supply pump for supplying water to the bidet nozzle (however, one of them also serves as water supply to the clean nozzle). Therefore, the changeover switch is not necessary and the life of the water supply pump can be extended. Further, the two water supply pumps 60a and 60b are the hot water storage tank 15
The elastic member 6 is suspended between the lower end and the bottom plate 3.
Since 1a and 61b are installed, the water supply pump 60
