However, in this type of conventional hot water washing device, the hot water tank is placed, for example, on one end side of the box 1, and the hot water washing nozzle or hot air fan for blowing hot air toward the buttocks after washing is installed. It is located in the center of the box and is therefore spaced apart from the hot water tank.

[Problems to be Solved by the Invention] It is desirable for the above-mentioned conventional hot water washing device to be able to spout hot water at an appropriate temperature for a long time, but in order to do so, the hot water tank must have a relatively large capacity. In conventional equipment, the bottom area of the hot water tank is limited, so in order to increase the capacity, the hot water tank must be tall.
There was a problem that the box could easily become large. Furthermore, since each part is separated and connected, the number of connection points for drain pipes, etc. increases, and the risk of water leakage, etc. increases.

[Means for Solving the Problems] In the present invention, a flat hot water tank having an installation area of at least 1/3 or more of the bottom area of the box is placed at the bottom of the box as a hot water tank provided inside the box. Furthermore, in the present invention, the interior of the hot water tank is divided into a plurality of small chambers by a partition wall, and openings are provided in the partition wall to communicate the small chambers so that water is sequentially passed through the plurality of small chambers. A water supply inlet was provided in the small chamber, a water outlet to the nozzle was provided in the most downstream small chamber, and a heater was provided in at least one small chamber.

[Function] In the hot water washing device of the present invention, the hot water tank is flat and placed at the bottom of the box, so the height of the box can be reduced. It is also possible to increase the capacity of the hot water tank. Furthermore, it is also possible to omit the drain pipe by connecting a hot water tank to each component.

In addition, in this invention, the inside of the hot water tank is divided into small chambers, so that the hot water is sufficiently stirred as it flows through the small chambers. Splashing of water is prevented.
