It is composed of a pump-equipped hot water tank configured so that no discharge pressure acts, and a nozzle that sprays hot water from the pump-equipped hot water tank, which is pumped from the discharge hole of the pump chamber to clean the private parts of the human body. It is characterized by the presence of

In the present invention, the water tank stores water to be supplied to the hot water tank with a pump, and can be a conventional water tank made of synthetic resin or metal.

The hot water tank with pump, which is an important component of the human body private part cleaning device of the present invention, is an integral structure of a container and a pump.

The container has a heater that heats the water supplied from the water tank and stores it as hot water. The shape of the container can be any shape taking into consideration the overall configuration of the device in which the container is placed. In addition, a water supply valve for keeping the volume of water in the container constant, a temperature sensor, and various other devices, sensors, and other devices used in conventional hot water tanks and the like are installed in this container.

A part of the wall that constitutes the container of the pump-equipped hot water tank constitutes a part of the pump. That is, the pump chamber of the pump is formed on the external surface of the wall of the container. This wall may be formed in a lower part of the upper part of the container. Alternatively, the upper part of the container may be inclined diagonally, and the inclined portion may be formed. Furthermore, it may be formed on the side wall surface of the container extending in the vertical direction. A wall that constitutes a part of this pump has a through hole that serves as a suction hole for the pump. A part of the outer circumferential surface of the wall surrounding this through hole becomes a part of the inner surface forming the pump chamber of the pump.

In the human body private parts cleaning device of the present invention, in the hot water tank with a pump, the inlet of the pump is opened into the container, so the discharge pressure of the pump does not act on the container constituting the hot water tank. Therefore, there is no need to make the structure of the container pressure-resistant. In addition, since the pump and container are integrally constructed, and part of the wall of the container also serves as part of the pump housing, the materials used to construct the pump-equipped hot water tank as a whole can be saved, and the equipment can be can be made compact. In addition, because the impeller of the pump is always submerged in hot water and kept warm, when pumping hot water from the hot water tank, the hot water is not cooled by the impeller and housing as in the case of conventional methods, and the initial period of ejected hot water is Cold water can be avoided.
