Abstract
Disclosed is a household appliance comprising: a door; a door lock unit equipped with a hook part which is configured to unlock and open the door by moving outward; a motor configured to generate torque by using electricity; a driving gear unit which has a rotary shaft at one end portion and is configured to rotate by receiving the torque from the motor, wherein the one end portion pushes the hook unit to the outside of the door lock unit to open the door when the driving gear unit rotates in one direction; a sensing unit configured to sense the displacement of the other end portion of the driving gear unit when the hook unit moves to the inside of the door lock unit, wherein the other end portion rotates in the opposite direction about the rotary shaft of the driving gear unit; and a control unit configured to control the operation of the motor on the basis of the displacement, sensed by the sensing unit, of the other end of the driving gear unit.
