A door lock structure and a washing machine using the door lock structure

Abstract

The invention relates to a door lock structure and a cleaning machine using the door lock structure. The door lock structure includes a bracket, a lock rod, a screw rod, a nut pair and a reversing sleeve, and the bracket is connected with a box body; the lock rod can be lifted up and down and It is rotatably constrained on the bracket, and the upper end of the lock rod has a limit block that can pass through the lock opening on the door body; the reversing sleeve is sleeved on the outer circumference of the nut pair to drive the nut pair to rotate circumferentially during the rising process of the nut pair to make the lock The stops at the top of the rod are either aligned or staggered with the latch. The door lock structure of the present invention can be integrally installed on the box body without occupying the space on the door body, and only a lock opening can be provided on the door body, the structure is reasonable, and the assembly is convenient; Pass through the lock on the door body, and then turn the lock rod relative to the lock port at a moving angle, and pull down the lock rod to lock the lock rod and the door body lock in dislocation, so that the process reliability after locking is better; when opening the door , first open the door body to a certain gap for steam to escape.

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

Although the above-mentioned structure can lock the door body on the dishwasher, its locking structure is complicated and the reliability is low; and when it is used for locking the door on a box body with an inner cavity, it is necessary to install a part of the structure on the door body In fact, for the relatively thin structure of the door itself, the above-mentioned locks have the problem of being inconvenient to assemble

[0004] In addition, for dishwashers, after cleaning, there is a large amount of steam remaining in the washing chamber, which is prone to negative pressure and difficult to open, and if it is opened suddenly, the hot steam will also seriously affect the customer experience; during the cleaning process, if the door There is a certain gap after the body and the box are locked, and there is also a risk of steam overflow
