Description of the Related Art When a hot water washing device is installed in a Western style toilet, a casing such as a toilet seat box or a low tank cover may be installed on the rear upper surface of the Western style toilet. In this casing, a nozzle for ejecting hot water and a hot water supply mechanism are incorporated, and further, a hot air drying mechanism, a deodorizing mechanism, and the like are further incorporated as necessary. This casing is
Usually, a hot water tank is installed inside. Water is supplied to the hot water tank via a water supply pipe.

When a washing switch is operated, warm water in the warm water tank is supplied to the washing nozzle, the hot water is spouted from the tip of the washing nozzle, and hot water is poured over the buttocks of the human body to perform washing. . Instead of hot water tapping,
Water flows from the water supply pipe into the hot water tank.

[0004]

In some cases, a heater is provided to prevent the water supply pipe from freezing. Conventionally, this heater is connected to a power outlet separately from the hot water cleaning device, but the outlet is often provided in the back of the toilet room, and it is difficult to insert a plug.

[0005] Further, since the heater is separate from the hot water washing device, the power supply control device for the heater is installed in the toilet room separately from the hot water washing device, and the space in the toilet room is reduced. .

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hot water washing apparatus in which a water supply pipe freezing prevention heater can be easily connected to a power supply.

Another object of the present invention is to provide a hot water washing apparatus in which the control circuit for supplying electricity to the heater is installed in a casing of the hot water washing apparatus.

[0008]

Means for Solving the Problems A hot water washing apparatus according to the present invention comprises a casing installed at the rear of a Western-style toilet bowl, a hot water tank installed in the casing, and hot water supplied from the hot water tank. And a nozzle for ejecting hot water from the nozzle, and a hot water washing device to which a water supply pipe is connected, wherein an energizing terminal for a heater for the water supply pipe is provided in the casing.

[0009] In such a hot water washing apparatus, since the energizing terminal portion of the heater for heating the water supply pipe is provided in the casing, the heater can be easily connected to the power supply.

In the present invention, it is preferable that room temperature detecting means and control means for controlling energization of the heater based on the detected room temperature of the room temperature detecting means are provided in the casing. According to such a hot water cleaning device, the control means is not separate from the hot water cleaning device, and the space in the toilet room is increased. Further, the cost can be reduced by using common circuit components.
