PROBLEM TO BE SOLVED: To eliminate requirement of an electric circuit and electric wiring, simplify a structure, reduce facility cost, eliminate electric shock, make operable even in service interruption, and improve safety and reliability, by employing a thermo-valve in a safety device of a shower bathing device, and passing only fluid with a specific temperature. SOLUTION: Hot water with a suitable temperature composed of mixture of hot water and cold water is supplied from a hot-water supply portion 1. When the temperature of the hot water is adequate, a safety device does not operate and shower is supplied from a hot-water outlet 4. A thermo-valve is made of a material deformable with temperature, and opens or closes a flow passage depending on the temperature of the fluid. In other words, a thermo- valve 2 for breaking flow of the hot water when the temperature of the hot water is higher than a set value, and a thermo-valve 3 for breaking the flow when the temperature is lower than the set value. For example, when the hot-water supply portion 1 fails and hot water higher than a maximum set value is supplied, the thermo-valve 2 is operated to stop hot-water supply. When cold water lower than a minimum set value is supplied, the thermo-valve 3 is operated to stop water supply. |
