定した実用新案登録請求の範囲第１項の浴槽。[Scope of Claim for Utility Model Registration] A temperature-sensitive operating valve 3 that closes in a temperature range above a set temperature is provided in the drain circuit of the bathtub, and the heat-sensitive portion of the temperature-sensitive operating valve 3 is exposed in the drain flow path. A bathtub in which the set temperature of a temperature-sensitive valve 3 is set to a temperature slightly lower than a temperature suitable for bathing. The temperature-sensitive actuated valve 3 is made of a shape memory alloy with one end being a fixed end and the other actuating end moving to a position corresponding to the memorized shape in a temperature range above a set temperature, and a free end of the shape memory alloy. It is composed of a connected valve body 4 and an operating shaft 40 that is connected to the valve body 4 to enable external operation and forcibly return the valve body 4 from the closed position to the open position. In terms of shape, the valve body 4 is in a closed state, and when the valve body 4 is forcibly returned to the open position, the shape memory alloy is plastically deformed. range 1
Sectional bathtub. The temperature-sensitive operating valve 3 is a bimetal whose one end is fixed and the other operating end is displaced according to the temperature of hot water or water that comes into contact with the bimetal, and a valve body 4 connected to the operating end of the bimetal. When the temperature is higher than the set temperature, the valve body 4 is closed, and when the temperature is lower than the set temperature, the valve body 4 is closed.
The bathtub according to claim 1, wherein the movement range of the operating end is set so that the valve is in an open state.
