Claims

[Scope of utility model registration request]

an antifreeze valve body connected to the rising portion of the water pipe; an actuator for operating the antifreeze valve body; a control circuit for controlling the operation of the actuator; The control circuit includes a temperature sensor that inputs an input to a control circuit, an external operation section that inputs an operation input to the control circuit, and a position detection means that detects the operating position of the actuator or the antifreeze valve, and the control circuit includes at least the Three position signals corresponding to the water flow position, water stop position, and water drain position of the antifreeze valve main body are memorized, and one of the at least three position signals is selected based on the input from the temperature sensor and the external operation unit. by selecting one as a reference signal and comparing the selected reference signal with the signal from the position detection means;
A remote-controlled antifreeze faucet, characterized in that the actuator is actuated and the antifreeze faucet main body is positioned at one of the water flow position, water stop position, and water drain position.
