Moreover, the gap between the opening on the side surface of the main body case and the drainage hole of the hot water tank is set to a distance such that the water discharged from the drainage hole does not splash outside the opening. For example, even if the toilet bowl is wider than the main body case, the water discharged from the warm water tank does not splash on the toilet bowl surface. Also, a container for collecting wastewater is not required.

The gap between the opening on the side surface of the main body case and the drainage hole of the hot water tank is such that the head of the drain plug removed from the drainage hole of the hot water tank is locked in the opening. Therefore, the drain plug can be prevented from dropping into the gap between the main body case and the hot water tank. Furthermore, the drain plug that seals the water drain hole of the warm water tank can be rotated by a coin inserted from the opening of the main body case to be removable, which
Draining work can be performed without the need for special tools.

The structure of the present invention will be described in more detail below with reference to embodiments with reference to the accompanying drawings.
