Next, a hot water supply operation to the cleaning tank (10) based on the above configuration will be described. The liquid level (X) specified by the rinse liquid level detector (17) in the rinse tank (14)
No rinse water is stored. Here, when the hot water supply switch (21) is pressed, the cleaning liquid level detection device (12) detects an empty state, so the liquid level switch (12A) is at the position shown in the figure, and the control relay (22) is excited. Then, the self-holding contact (22A) and the normally open contact (22B) are closed. This allows
The hot water supply solenoid valve (16) is independent of the rinsing liquid level detecting device (17), that is, even if the detecting device (17) detects the predetermined liquid level (X) of the rinsing tank (14), the control relay ( Power is supplied through the normally open contact (22B) of (22) to open and supply the rinse water from the water heater to the rinse tank (14). Therefore, the liquid level in the rinsing tank (14) rises, and the rinsing water that has passed through the upper end opening of the hot water supply overflow pipe (20) falls through the overflow pipe (20) into the cleaning chamber (3), and is washed. Hot water is supplied to (10).

When the rinse tank (10) is supplied with rinse water of a predetermined liquid level (Y) from the rinse tank (14) via the overflow pipe (20), the cleaning liquid level detector (12) detects this. Since the liquid level switch (12A) switches, the excitation of the control relay (22) is released and the self-holding contact (22A)
The normally open contact (22B) is normally opened. This allows
The energization of the hot water supply electromagnetic valve (16) is cut off, the electromagnetic valve (16) closes, the hot water supply to the rinsing tank (14) is stopped, and the initial hot water supply operation to the cleaning tank (10) ends.
