As the residual water release mechanism and the unsuitable temperature water release mechanism, various known mechanisms can be adopted. However, the valve opening to the discharge passage is opened and closed by the valve body provided in each mechanism, and the unsuitable temperature water release mechanism is used. And those that discharge residual water. For example, a venturi is provided in the supply path, the vent path is opened to the venturi, and when hot water flows in the supply path, hot water does not flow into the discharge path due to the Venturi effect.
At the time of stopping water or inflow of unsuitable temperature water, the supply path may be closed by the movement of the valve body, so that residual water or unsuitable temperature water may flow into the discharge path opened to the venturi. In this aspect, it is preferable to provide a check valve in the discharge passage so that air is not sucked from the discharge passage when hot water flows in the supply passage.
