Description

[Brief explanation of drawings]

Figure 1 is a schematic diagram showing one embodiment of the present invention;
The figure is a perspective view of the same hot water washing device as above, and FIG. 3 is a schematic cross-sectional view, in which 1 is a water pipe, 2 is a water distribution pipe, 3 is a cold water pressure reducing valve, 4 is a hot water pressure reducing valve, 18 is a drain port, and 23 is a The appropriate temperature water supply port A is a hot water storage mixing tank.

Claims (1)

[Scope of utility model registration request] The tip of the water pipe that sends hot water is branched into two water distribution pipes, and one of the water distribution pipes is equipped with a cold water pressure reducing valve that utilizes transformation deformation of a shape memory material to operate at a temperature below the optimum minimum temperature. Attach a hot water pressure reducing valve to the other water distribution pipe that utilizes the transformation deformation of a shape memory material to reduce pressure at a temperature above the upper limit temperature, so that when either pressure reducing valve operates to reduce pressure, hot water will be released. A cold and hot water removal device for a hot water cleaning device, characterized in that hot water is discharged from a drain port and is sent to an appropriately hot water supply pipe when neither pressure reducing valve operates to reduce the pressure. A cold water removal device for a warm water bidet toilet seat, characterized in that a hot water storage mixing tank is connected to a hot water pipe.
