There is a slight gap between them, and the tank tray 64 and the low tank 66 have a double tank structure. The peripheral edge of the opening 74 of the tank tray 64 rises upward, and the low tank 66 is placed on this portion. As a result, there is a slight gap between the bottom surface of the raw tank 66 and the bottom surface of the tank tray 64, and water can flow through this gap.

A flow valve 80 is mounted so as to penetrate the side surface of the low tank 66. This flow valve 80
Has an inlet 82 at the tip and an outlet 84 at the rear, and switches the communication between the inlet 82 and the outlet 84 by moving a valve body (not shown in FIG. 1) with the handle 86. It is configured as follows.

When the flow valve 80 is opened, the water in the low tank 66 flows out of the flow valve 80 between the tank tray 64 and the low tank 66 and flows from the drain port 76 into the washing water flow path 72. Since the flush water channel 72 communicates with the toilet bowl of the Western-style toilet bowl 60, the water (flowing water) flowing into the flush water channel 72 flows into the toilet bowl and flows from the toilet bowl to the drain pipe. By keeping the flowing water flowing, freezing of water in the water supply pipe, the drain pipe, and the toilet bowl is prevented.

The water in the low tank 66 is supplied to the flow valve 80
When the water flows out of the low tank 66, a ball tap 89 provided on the upper part of the low tank 66 opens, and the water tank 88 opens the ball tap 89.
Water is supplied into 6.
