Claims

[Scope of utility model registration request]

A fully automatic washing machine has a water tank suspended in a vibration-proof manner inside the outer box, a rotating tank is installed inside the water tank, and rotary blades such as a pulsator or agitator are installed inside the rotating tank, and the lever is operated. In the washing machine safety device, a safety switch combined with a micro switch is installed between the outer box and the water tank as a second safety switch. A safety device for a washing machine characterized by being provided with a selection switch for selecting either a lever-type safety switch or a second safety switch using a seismic sensor.
