The check valve 6 and the flow rate adjustment valve 7 are connected to the heat exchanger 1.
It is also possible to maintain the toilet seat 2 at a comfortable temperature at all times by providing natural convection of hot water within the heat exchanger 14 and the toilet seat 2. Alternatively, as shown in FIG. 6, the hot water pipes 8 and 9 may be constructed of only one pipe 30 and inserted into the heat exchanger 14. In this case, it is necessary to form the hot water pipe 30 with a large diameter, and since vertical convection of hot water is always performed inside the pipe 30, the hot water pipe 30 inside the heat exchanger 14 is cooled. Nor.

As shown in FIG. 3, the toilet seat 2 has a hollow hot water storage chamber 11 formed therein, and the hot water storage chamber 11 is formed all around the inside of the toilet seat 2. Note that if the upper wall of the toilet seat 2 is made of a material with good thermal conductivity and the lower wall is made of a material with excellent heat insulation properties, a heated toilet seat with high thermal efficiency can be obtained. There is no specific question as to whether or not processing is required.

Further, a hot water jet device 12 for washing private parts is attached to one side of the back of the toilet seat 2.

The hot water jetting device 12 consists of an operating lever 21, a shower nozzle 22, a temperature suction pipe 24 whose one end has a water intake port 23 facing the hot water storage chamber 11 of the toilet seat 2, and the like. Therefore, the shower nozzle 22 is swung and fixed at each of the standby position, the washing position, and the bidet position, and the hot water suction pipe 24 is fixed at a fixed position at any angular position of the shower nozzle 22, so that hot water can be stored. One end of the hot water inside the chamber 11 is connected to the water intake port 23.
The hot water is drawn in from the shower nozzle 22 through the hot water suction pipe 24 and the like, and hot water is jetted out from the shower nozzle 22. Note that the hot water ejector 12 is not limited to the one side position of the toilet seat 2, and may be installed, for example, at the center of the back surface of the toilet seat 2.

The movable pipe joint 4 attached to one side of the rear end of the toilet seat 2 is provided on the side of the base 13, and is attached to one side of the rear end of the toilet seat 2.
It is constructed so that the hot water inside will not leak out even during the up-and-down operation. Note that a hot air fan may be attached to the cylindrical connecting portion 5 as needed in a place with low humidity. In this case, as shown in FIG. 4, the interiors of the toilet seat 2 and the cylindrical connecting portion 5 can be connected by a single pipe, which can be used as a ventilation path for the hot air fan 14'.

In the above configuration, the hot water flow path of the device according to the present invention will be explained as follows.

The raw water supplied to the heat exchanger 14 through the raw water supply pipe 10 is heat exchanged and heated inside the heat exchanger 14 by the heat exchange pipe 18 that connects the hot water pipes 8 and 9, as shown in FIG. , the water will be at an appropriate temperature. This hot water passes through the hot water pipe 19, the flexible pipe 20, the flow rate adjustment valve 7, the check valve 6, the movable pipe joint 4, and the cylindrical connection part 5 in order, and flows into the hot water storage chamber 11 inside the toilet seat 2.
