A power-saving socket for clothes belongs to the technical field of electrical products. The utility model is provided with a single chip microcomputer, a motor current detection circuit, a motor voltage sampling circuit, an optocoupler isolation and bidirectional thyristor control circuit and a protection circuit in a three-phase power socket, so that the single chip microcomputer can calculate the current detection signal, judge whether the motor connected to the socket is empty or full, and indirectly control the conduction angle of each phase thyristor according to the current. So as to control the input voltage of the motor under no-load and load, the input voltage is low when the motor is under no-load, and the input voltage is correspondingly increased when the motor is under load, so as to save electricity and energy. When the motor needs protection due to overvoltage, phase failure, overload and other faults, the output signal of the single chip microcomputer triggers the protection circuit to protect the motor. The utility model has the advantages of simple circuit structure, reliable performance, energy saving, enterprise production cost reduction and economic benefit improvement, and has strong practicability.
