There is something I did.

In this type of toilet bowl with a hot water washing device, since the capacity of the hot water tank is large, the toilet seat box is provided with an overhanging portion that projects to the side of the toilet bowl, and the hot water tank is installed in this overhanging portion. Is common.

In some cases, the hot water tank is separated from the toilet seat box, and the hot water tank and the toilet seat box are separately installed in the western toilet bowl so that the hot water tank and the toilet seat box are separately assembled.

[0005]

When the toilet seat box is provided with an overhanging portion and a hot water tank is installed in this overhanging portion, the height of the toilet seat box can be reduced, but at the rear of the overhanging portion. There is a problem that maintenance, inspection work and cleaning are difficult to perform. In addition, when the wall surface of the toilet room is close to the Western-style toilet, there is a case where the hot water cleaning device cannot be installed due to the overhanging portion.

Separate the hot water tank from the toilet seat box,
For toilets with a hot water cleaning device installed in the pedestal part of a Western-style toilet separately from the toilet seat box, when installing or removing the hot water cleaning device and repairing it, attach and detach the toilet seat box and attach the hot water tank. It is necessary to remove each, and workability is poor. Especially,
Since this toilet seat box and hot water tank are connected by tubes and electric wires, the toilet seat box and hot water tank must be attached and removed so that the tubes and electric wires do not come off or get entangled, and workability is considerably poor. .

A remote controller 23 is provided on the wall surface of the toilet room to allow remote control of the hot water cleaning device. A switch unit 24 is also provided on the upper side surface of the toilet seat box 2. The switch section 24 is covered with an opening / closing cover 25.

When the shower switch provided on the remote controller 23 or the switch unit 24 is pressed, the shower nozzle 7 is operated, hot water is ejected from the tip of the shower nozzle 7, and the user's buttocks are washed with a shower (anal washing). When the charm switch is pressed, the charm nozzle 8 is activated, and hot water is ejected from the tip of the charm nozzle 8 to wash the human buttocks with warm water (bidet wash). When the warm air switch is pressed, the warm air fan 10 is operated, and the warm air is blown from the warm air outlet 10a to the human buttocks to perform drying. When the stop switch is pressed, the operation of the shower nozzle 7, charm nozzle 8 or warm air fan 10 is stopped.

In the toilet bowl with a hot water cleaning device constructed in this way, since the hot water tank 15 and the pump 16 are integrated with the toilet seat box (casing) 2, the hot water tank 15 and the toilet seat box 2 are integrated. It can be attached to and detached from the western-style toilet 1, and this workability is significantly improved.

Since the entire warm water tank 15 is disposed below the toilet seat box 2 and is inserted into the western style toilet 1 through the opening 18 of the western style toilet 1, the toilet seat box 2 is used for the warm water tank. No space is required at all, and the height of the toilet seat box 2 can be reduced. Further, it is not necessary to provide the toilet seat box 2 with an overhanging portion to the side of the Western-style toilet for storing the hot water tank. Therefore, maintenance / inspection work and cleaning at the rear of the western-style toilet can be easily performed. Further, even when the wall surface of the toilet room is close to the side of the western-style toilet, the hot-water washing device can be installed in this western-style toilet.

In this embodiment, since the shower nozzle 7 and the charm nozzle 8 are arranged above the hot water tank 15, the nozzles are heated by the heat of the hot water tank 15 (especially, the warm air flow warmed by the hot water tank and rising). 7,
The pipe at or near 8 is warmed. Further, the circuit board 12 is arranged in the vicinity of the nozzles 7 and 8, and the circuit board 12 is installed so that the surface on which the circuit components are mounted faces the nozzles 7 and 8. Therefore, the nozzles 7 and 8 are warmed by the heat radiation from this circuit component. This allows
Freezing of water in the pipes in the vicinity of the nozzles 7 and 8 in cold regions is prevented. In the present embodiment, since the pump 16 is also arranged above the hot water tank 15, this pump 16 is also warmed by the hot water tank 15 and the freezing of water in the pump 16 or the pipe in the vicinity of the pump 16 is prevented. It

As described above, the nozzles 7 and 8 and the pump 1 are
By warming 6 or the pipes in the vicinity thereof, it is possible to completely eliminate or significantly reduce the initial cold water (the low temperature water is ejected from the nozzle at the start of cleaning).

In the above embodiment, the entire hot water tank 15 is arranged below the base plate 2a of the toilet seat box 2, but in the present invention, the upper portion of the hot water tank 15 may be inserted into the toilet seat box. . In this case, the pump 16 may be arranged at another place in the toilet seat box, or may be arranged at the side or the lower side of the hot water tank.
