水混合管から得られる湯の温度を自動的に設定温
度に制御する湯水混合水栓に関する。[Detailed Description of the Invention] The present invention relates to a hot water mixing faucet that automatically controls the temperature of hot water obtained from a hot water mixing pipe of a bath, shower, water heater, etc. to a set temperature.

の湯の温度を自動調温するものが知られる（特公
昭56−24148号公報参照）。 A conventional hot water mixing faucet includes a hot water pipe having a hot water valve, a water pipe having a water valve, and a hot water mixing pipe that joins these two pipes, and the hot water valve and the water valve are installed in the hot water mixing pipe. There is known a system in which a temperature-sensitive member is disposed in conjunction with the hot-water mixing pipe, and the temperature of a constant flow of hot water obtained from the hot-water mixing pipe is automatically controlled by the temperature-sensitive member (see Japanese Patent Publication No. 56-24148).

ましい。 However, according to this method, when the water supply temperature becomes extremely low in winter, there is insufficient heating in the heat exchange section on the upstream side connected to the hot water pipe, and the temperature sensitive member opens the hot water valve fully and causes the water valve to open completely. Even if the pipe is fully closed, hot water at the desired set temperature may still not flow from the hot water mixing pipe. In this case, operate the manual hot water output amount control valve in the hot water mixing pipe to the throttle side, thereby reducing the amount of hot water from the hot water pipe, that is, the amount of water passing through the upstream heat exchange section connected to it, and The heating temperature of the exchange part is raised so that a smaller flow rate of hot water than usual can be obtained from the hot water mixing pipe at the desired set temperature, but this is time consuming and it is preferable to automate this operation.
