Household appliance safety door lock

Abstract

A household appliance safety door lock comprises a base, a door hook, a first sliding block, an electromagnetic switch box and a second sliding block arranged between the electromagnetic switch box and the base. A door lock opening is formed in the position, corresponding to the door hook, of the base. A limiting opening is formed in the middle of the first sliding block. The electromagnetic switch box comprises a box base, a static contact arranged in the box base, a movable contact spring which is arranged in the box base and is opposite to the static contact, a locking block which movably protrudes out of the bottom surface of the box base, and an ejector rod which is positioned on one side, far away from the box upper cover, of the movable contact spring and movably protrudes out of the bottom surface of the box base; the limiting opening is movably opposite to the locking block, an acting protruding block is arranged on one side of the second sliding block in a protruding mode, a guide inclined face is arranged on the acting protruding block, and the ejector rod is located above the acting protruding block. Therefore, the use state of the door can be truly corresponding, so that the conduction circuit is controlled to be switched on or switched off, and the safety is improved.

Description

technical field [0001] The invention relates to the related technical field of household appliances, in particular to a household appliance safety door lock. Background technique [0002] A household appliance, such as a washing machine or a dishwasher, has a door that can be opened or closed, and a door lock is provided on the door.
