Due to the pressure, the hot water that has accumulated near the temperature sensing member 15 is forced out into the shower hose 3 through the leak hole 20.
Therefore, the temperature around the temperature-sensitive member 15 is quickly replaced with new hot water and lowered, compared to storing high-temperature hot water and mixing it with new hot water. The time from the point of hot water supply operation to the contraction operation of the temperature sensing member 15, that is, the opening operation of the valve 7, is shortened, and the responsiveness of hot water spouting at the time of resupply is improved. Note that the leak hole 20 may be provided in the seat surface 9 of the valve.

Effects of the Invention As described above, according to the first invention, when hot water reaches a temperature higher than the safe operating temperature during use, the valve automatically shuts off the mixed hot water passage, so that hot water does not flow from the shower spout or faucet. It does not eject, preventing risks such as burns, and reduces thermal stress on temperature-sensitive components due to high temperatures.
Improved reliability. Furthermore, according to the second and third inventions, in addition to exhibiting the effects of the first invention, after the valve is shut off by supplying hot water, new hot water adjusted to a safe temperature for use is supplied. In such a case, the newly supplied hot water pressure will push the hot water that had accumulated in the safety device out of the leak hole or the hot water discharge pipe, so that the area around the temperature-sensitive member will quickly reach hot water at a safe temperature for use. The return time of the temperature-sensitive member is shortened, and the responsiveness up to the spouting of hot water is improved compared to when the hot water is resupplied.
