[Detailed Description of the Invention] 1. Field of Industrial Application] The present invention relates to a private parts cleaning device for cleaning the anus after defecation, cleaning the female private parts during errands, or during menstruation. This is related to the technology you are trying to improve.

[Prior Art] Conventionally, in a private parts cleaning device equipped with a private parts cleaning nozzle 1 and a cleaning hot water tank 2 for supplying hot water to this private parts cleaning nozzle, the private parts cleaning device A is used as shown in Fig. tJIJ8. It is attached to toilet bowl B with bolts and nuts (not shown). As shown in FIG. 9, the cleaning hot water tank 2 has a safety bimetal thermostat 4 attached to the top surface of the tank body 5 via a mounting bracket 6, and the mounting bracket 6 is formed in a concave shape. 6 is arranged so as to face the inner upper surface of the tank body 5.

[Issue to be solved by the invention jI11 However, as shown in FIG. The hot water tank 2 is also tilted. When the cleaning hot water tank 2 is tilted in this way and the water level of the internal cleaning hot water drops, an air layer E with low thermal conductivity is interposed between the mounting bracket 14c6 of the bimetallic thermostat 4 and the hot water surface. As a result, it is difficult to conduct heat to the bimetallic thermostat 4 via the mounting bracket 6, and when the hot water temperature rises above a certain level, the bimetallic thermostat 4 operates to cut off the power to the electric heater 7, and The safety function that prevents the temperature from rising above this level does not work properly, and the bimetal thermostat 4 is activated only after the temperature of the hot water for cleaning rises considerably, and the nozzle 1 for private cleaning uses a considerably high temperature for cleaning. There was a problem with hot water gushing out. By the way, when installing the toilet bowl B at a level so that it does not tilt, when considering the above-mentioned problem with the private cleaning device A, the leveling is done with great care, but if this is not the case, the toilet bowl At present, it is difficult to determine exact levels.

The present invention was made in view of such problems,
The purpose is to provide a private parts washing device that is highly reliable in terms of safety and allows the bimetallic thermostat to operate as specified even if the toilet bowl is tilted to some extent.

[Means for Solving the Problems] The private parts cleaning device of the present invention includes a heat transfer rod 3 having good thermal conductivity inserted into the inside of the hot water tank 2 for cleaning, and a safety rod 3 attached to the top of the hot water tank 2 for cleaning. The bimetal thermostat 4 is connected in a thermally conductive manner.

[Function] In this way, heat can be conducted between the heat transfer rod 3 with good thermal conductivity inserted into the inside of the hot water tank 2 for washing and the bimetal thermostat 4 for safety attached to the top of the hot water tank 2 for washing. By connecting, even if the hot water tank 2 for cleaning of the private parts cleaning device is tilted, the heat transfer rod 3 can be connected to the tank body 5.
The bimetallic thermostat 4 prevents a gap from forming between the heat transfer rod 3 that hangs down to the inside of the tank body 5 and is immersed in the hot cleaning water in the tank body 5 to detect the temperature of the hot cleaning water and the surface of the hot cleaning water. As soon as the temperature of the hot cleaning water reaches a predetermined temperature, it is activated to cut off the power to the electric heater 7, for example, to ensure safety.
