Door lock structure and cleaning machine applying same

Abstract

The invention relates to a door lock structure and a cleaning machine with the door lock structure. The door lock structure comprises a shell with a lock hole; an ejector rod which moves upwards and can penetrate through the lock hole, wherein a lock opening is formed in the upper portion of the ejector rod, and the top, located above the lock opening, of the ejector rod is columnar; a lock catch which is rotatably arranged in the shell and located above the lock hole, a locking groove is formed in the lock catch, wherein the top of the ejector rod can be limited in the locking groove so as to lock the ejector rod; a first elastic piece which enables the locking groove to keep a downward trend; a locking plate which is arranged in the shell and can move back and forth relative to the lock hole, wherein a limiting structure is arranged between the locking plate and the lock catch; a second elastic piece which enables the locking plate to always keep a trend of moving forwards; and a driving mechanism which is used for driving the locking plate to overcome the elastic force of the second elastic piece to move backwards, so that the locking state of the lock catch and the ejector rod is released. The door lock structure is low in dependence on electric control logic.

Description

technical field [0001] The invention relates to a door lock structure 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. Although the above-menti...

Problems solved by technology

[0005] But this door lock device has the risk that the door is not tightly closed, because when the latch is inserted to make the door in the closed state, the door lock spring is in a compressed state, and in the closed state, the latch is in contact with the door lock switch lever, and the force of the spring It will be transmitted to the bolt so that the bolt has a tendency to move away from the door lock sensing support, and because the two sides of the door lock bolt have rounded bosses, the door lock bolt can be pulled out after an external force is applied, and the force applied by the spring Even if the force is not enough to make the door lock pin come out completely, there is still a tendency to make the lock pin move out of the door lock sensing support, resulting in the possibility of the door not being tightly closed.
