A door lock structure for electrical appliances and a cleaning machine using the door lock structure

Abstract

The invention relates to a door lock structure for electrical appliances and a cleaning machine using the door lock structure. The door lock structure for electrical appliances includes a housing, a lock bar, a lock buckle, a second elastic member, a stopper, a first An elastic part, an operating part, a restricting part and a driving mechanism. The present invention has low requirements on electric control logic. When locking is required, the lock lever moves down and presses against the lock catch to drive the lock catch to rotate, so that the upper end of the lock catch gradually cooperates with the lock mouth at the lower end of the lock rod to limit each other, and the driving mechanism drives The operating part moves up, and then drives the restricting part to move to the left to limit the position of the buckle, prevent the buckle from turning upwards, and realize locking; when it needs to be unlocked, the driving mechanism drives the operating part to move down, and the restricting part then moves to the right , Cancel the limit on the lock position, at this time, lift the door body upwards, the lock rod can move upwards under the drive of the door body to realize unlocking; the whole process is simple, reliable and easy to realize.

Description

technical field [0001] The invention relates to a door lock structure for electrical appliances and a washing machine applied with the door lock structure. Background technique [0002] For a box with a functional inner cavity, due to functional requirements, a door that can open or cover the port is usually provided at the port of the box, and during the use of the box, the door needs to be relatively The case is locked. [0003] For example, the Chinese invention patent application with the application number CN200410043122.5 "Door switch mechanism and dishwasher with the door switch mechanism" (application publication number: CN1550202A) discloses a structure, which includes: in order to switch on and off the dishwasher A door configured to be rotatable from the cutlery input port, and a rotation assist mechanism that applies a rotation assist force to the door along with the rotation of the door; the rotation assist mechanism extends from a closed state to a predetermin...
