Washing machine door lock

Abstract

The invention provides a washing machine door lock and belongs to the technical field of washing machine door locks. The washing machine door lock comprises a door hook, a lock shell, a rotating piece, an elastic rotating piece restoring piece, a lock catch, a lock matching mechanism and lock catch unlocking mechanism. When a washing machine door is closed, the door hook is inserted into the lock shell, the rotating piece is driven by the door hook, the lock matching mechanism guides the lock catch to move from a lock catch restoration position to a lock catch locking position so as to block on a returning path of the rotating piece, and then the washing machine door is locked. After washing is finished, an electromagnetic driving piece drives the lock catch to move along a direction far away from the lock catch restoration position continuously through the lock catch unlocking mechanism, the lock catch is enabled not to block on the returning path of the rotating piece, the rotating piece returns under an action of the elastic rotating piece restoring piece to enable the door hook to pop out from the lock shell, and then the washing machine door is unlocked. The washing machine door lock has the advantages that the washing machine door can be unlocked through the electromagnetic driving piece, and a handle for pulling the washing machine door no longer needs to be arranged on the outside of a door sheet.

Description

technical field [0001] The invention relates to the technical field of washing machine door locks, in particular to a washing machine door lock.

Problems solved by technology

[0005] Therefore, the technical problem to be solved in the present invention is to overcome the door lock rotation structure in the prior art and need to apply outward pulling force when the door hook is drawn out. This door lock rotation structure cannot be used in washing machines without handles outside some washing machine doors. , so as to provide a washing machine door lock that does not need to apply outward pulling force when the door hook is pulled out
