Door lock structure for electric appliance and cleaning machine applying door lock structure

Abstract

The invention relates to a door lock structure for an electric appliance and a cleaning machine applying the door lock structure. The door lock structure for the electric appliance comprises a shell, a lock rod, a lock catch, a second elastic piece, a retainer, a first elastic piece, an operating piece, a limiting piece and a driving mechanism. The requirement for electric control logic is low, when locking is needed, the lock rod moves downwards and abuts against the lock catch to drive the lock catch to rotate, the upper end of the lock catch is gradually matched with a lock opening in the lower end of the lock rod for mutual limiting, the driving mechanism drives the operation piece to move upwards, then the limiting piece is driven to move leftwards, the position of the lock catch is limited, the lock catch is prevented from overturning upwards, and locking is achieved; when unlocking is needed, the driving mechanism drives the operation piece to move downwards, the limiting piece moves rightwards along with the operation piece, limiting on the position of the lock catch is cancelled, at the moment, a door body is opened upwards, the lock rod can move upwards under driving of the door body, and unlocking is achieved; 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....

AI Technical Summary

Problems solved by technology

Although the above structure can lock the door body on the dish washer, its locking structure is complex, highly dependent on electric components and control methods, the logic of the door lock action is complicated, prone to failure, and low in reliability
