1 and the N / C contact 212 are alternately switched.

That is, the relay 21 has an N.O contact 21.
When 1 is on, the hot water heating control circuit 18 is operated and the operation of the hot air heating control circuit 22 is stopped, while
When the N / C contact 212 is on, the hot air heating control circuit 22 is operated and the operation of the hot water heating control circuit 18 is stopped, and such operation is continuously repeated.

Thereafter, the hot water heater control circuit 18 operates the hot water heater 9 so as to keep the water temperature of the water stored in the storage tank 8 constant, and the hot air heating control circuit 22.
Controls the warm air heater 12 based on the value detected by the indoor temperature sensor 13 so as to keep the room temperature of the toilet constant.

As described above, in this embodiment, the hot water heating control circuit 18 and the hot air heating control circuit 22 are time-divisionally on / off controlled, and the on / off cycle in the on / off control is shortened. This causes the fan 11 to rotate by inertia,
Even when the power supply to the warm air heating control circuit 22 is turned off, the warm air heated by the residual heat of the warm air heater 12 is blown.

Further, in this embodiment, even when the boiling water heater 9 is boiling, the relay 21 receives the oscillation circuit signal from the oscillation circuit 20 at a cycle of 1 second and the duty ratio is 50% to control the boiling water. Circuit 18 and warm air heating control circuit 2
Since 2 is turned on / off, AC power can be supplied to the fan 11 and the warm air heater 12 at 0.5 second intervals, and warm air heating is possible.

Further, the relay 21 receives the oscillation circuit signal from the oscillation circuit 20 to turn on / off the hot water heating control circuit 18 and the hot air heating control circuit 22, so that the electric capacity of the entire device need not be increased, Therefore, it is possible to prevent an increase in the cost of electricity bills, and because the general outlet provided in the toilet does not require special work, it is easy and
The burden of construction costs can be reduced.

In this embodiment, the oscillation circuit signal output from the oscillation circuit 20 turns on / off the relay 21 at a cycle of 1 second and at a duty ratio of 50%, and synchronizes with the relay 21. Although the hot water heater 9 is always on / off controlled, other than this, the hot water heater 9 does not have to be constantly turned on / off when the hot air heating is stopped, and the output from the oscillation circuit 20 is not necessary. Alternatively, the duty ratio of the oscillation circuit signal may be set to a value other than 50%, and the ON / OFF operation of the relay 21 may be performed according to the duty ratio.

As another embodiment, in addition to the configuration of the above-described embodiment, a warm air heater for giving warm air to the human body part is further provided as warm air drying means for drying the human body part with warm air.
The apparatus main body is provided with a fan, and the toilet bowl 2 is provided with a hot air outlet, and the hot water heating means, the hot air drying means and the hot air heating means are relayed based on the signal from the oscillation circuit from the oscillation circuit. It may be configured to be used and switched alternately.

In this embodiment, the toilet can be used more comfortably by having the warm air drying means for drying the human body part with warm air.

[0039]

As described above, according to the present invention, the hot water heating means and the hot air heating means are turned on / off in a time division manner so that the hot water heating means and the hot air heating means are operated alternately. The warm air heating means heats the toilet room with warm air. Therefore, even when the toilet is used, particularly when it is continuously used, it is possible to prevent the temperature in the toilet room from lowering and to use the toilet comfortably.

Furthermore, the toilet can be used more comfortably by providing the warm air drying means for drying the human body part with warm air.

Since the control means controls the hot water heating means and the hot air heating means on / off in a time-division manner, it is not necessary to increase the electric capacity of the entire apparatus, and it is possible to prevent an increase in the electricity charge cost, and to use the toilet. Since the general outlet provided does not require special work, it is easy and the burden of construction costs can be reduced.
