As is clear from the above description, the following effects can be obtained according to the sanitary washing device of the present invention.

By providing a relief function that opens when the internal pressure of the hot water tank becomes equal to or higher than a set value and provides water to the toilet opening in the auxiliary water passage communicating from the hot water tank into the toilet opening, the auxiliary water passage can be simplified and shortened. This eliminates the need for piping components such as a water discharge hose and a distributor that also serves as a flow control valve, which is advantageous in terms of cost and space, and the relief function reduces the flow rate of the main water channel when the water source pressure is high. When the internal pressure of the hot water tank becomes high such as when the water tank is squeezed, water is passed through the opening of the toilet, so that the hot water tank can be protected against pressure.

In the hot water tank, there is provided a partition plate which partially communicates with a portion having a heater, and a bypass channel which does not pass through the heater from the outlet of the inlet channel to the inlet of the sub channel is formed. The water from the inlet channel is directly passed through the water channel without being heated, and the water kept in the hot water tank is pushed up in the hot water tank without being stirred, so that the thermal efficiency can be increased.

The hot water tank upper member having a rib as a partition plate on the inner surface of a portion one step lower than the height of the hot water tank and the hot water tank lower member are connected to each other to form an inner peripheral portion of the hot water tank upper member. And the inner periphery of the lower portion of the hot water tank and the ribs, the bypass water passage can be formed integrally with the hot water tank, and can be easily manufactured.

The sub-channel is communicated from the lower portion of the hot water tank, and the sub-channel is provided with a drain valve in parallel with a relief valve as a relief function. When the set value of the relief function is set higher than the head pressure of the hot water tank, it is possible to prevent the hot water from flowing out of the hot water tank when the water is stopped.

The sub-channel is communicated from the lower portion of the hot water tank, and the sub-channel is provided with a drain valve in parallel with a relief valve as a relief function, so that the configuration of the sub-channel can be simplified.

Furthermore, since the drainage tap provided with the relief valve having the relief function is attached to the lower part of the hot water tank, the sub-channel is constituted only by the drainage tap having the relief function provided at the lower part of the hot water tank. It is advantageous in terms of space and space.

Further, the drain plug has a cylindrical shape, and has a seal member on the side of the hot water tank for watertightly attaching the hole in the lower part of the hot water tank, and a lever for rotating the drain plug on the spout side. By doing so, the sealing property of the sealing member is relaxed, so that merely by moving the lever, the sealing property of the sealing member of the drain plug is relaxed, and the drainage from the hot water tank or the like can be easily performed.
