The invention discloses a household electric appliance electric leakage protection socket comprising a power supply jack and an electric leakage protector which is connected with the power supply jack. The electric leakage protector comprises an electric leakage detection module, an electric outage execution module and a power supply module which supplies DC power supply VCC to the electric outage execution module. The electric leakage detection module is composed of a rectifier diode, a first current-limiting resistor and an optoelectronic coupler. The electric outage execution module comprises a trigger circuit, an execution circuit and an alarm circuit. The trigger circuit is composed of a 555 timer, a pull-up resistor, a timing resistor, a timing capacitor and an anti-interference capacitor. The execution circuit is composed of a coil of a relay, a normally-closed contact point of the relay and a freewheeling diode. The alarm circuit is composed of a second current-limiting resistor, a triode, a loudspeaker, a third current-limiting resistor and a red light-emitting diode. When electric leakage occurs in household electric appliances, the socket can generate acousto-optic alarm and cut off power so that the socket is simple in circuit structure, high in reliability of electric leakage protection, long in the service life and low in manufacturing cost.
