Abstract

The invention relates to a door lock structure for an electric appliance and a cleaning machine applying the door lock structure. The requirement for electric control logic is low, when locking is needed, a lock rod moves downwards and abuts against an ejection piece to move downwards, and in the downward moving process of the ejection piece, the ejection piece drives a lock catch to rotate, so that the upper end of the lock catch is gradually matched with a lock hook and presses the lock hook downwards; a driving mechanism drives a limiting block to move towards the ejection piece and limit the position of the ejection piece, and locking is achieved; when unlocking is needed, the driving mechanism drives the limiting block to move to cancel position constraint on the ejection piece, and at the moment, the lock rod can be driven by a door body to move upwards to achieve unlocking; and the whole process is simple, reliable and convenient to implement.

Description

technical field [0001] The invention relates to a door lock structure for electrical appliances and a washing machine using 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, it is necessary to place the door relative to the The cabinet is locked. [0003] For example, the Chinese invention patent application "Door Switch Mechanism and Dishwasher with the Door Switch Mechanism" (application publication number: CN1550202A) with application number CN200410043122.5 discloses a structure, which includes: The tableware inlet is configured as a door that can be rotated, and a rotation assist mechanism that applies a rotation assist force to the door along with the rotation of the door; When the door is inside, the door is applied with a rotation assisting force in the direction of closing....
