Locking and unlocking mechanism

Abstract

The invention relates to a locking and unlocking mechanism. The mechanism is characterized by comprising a movable clamping part and a clamping part, the clamping part is a transmission part (13), the movable clamping part comprises a power device, a transmission structure, a lever structure and a lock piece, a power arm of the lever structure is connected with the power device through the transmission structure, and a resistance arm of the lever structure is provided with a lock piece; the power device acts on the power arm of the lever structure to make the locking piece enter or go out ofa clamping groove (131) to be locked or unlocked.

Description

technical field [0001] The invention relates to a locking and unlocking mechanism of a drum washing machine. Background technique [0002] After the washing machine has been used for a period of time, the appearance looks bright and new, but the space between the outer wall of the inner cylinder and the inner wall of the outer cylinder is full of dirt. These dirt contain harmful bacteria. If these dirt are not removed in time, it will cause harm to people. Health damage. [0003] In the prior art, the removal of dirt between the inner and outer barrels mainly includes the following methods and the following deficiencies: [0004] (1) Although the existing method of physically disassembling the inner cylinder for cleaning can completely remove the dirt, ordinary consumers will not disassemble or disassemble it is not easy, so it cannot be widely promoted. [0005] (2) In the prior art, the cleaning agent can also be used to clean the dirt, but in fact the cleaning effect of...

AI Technical Summary

Problems solved by technology

[0004] (1) Although the existing method of physically disassembling the inner cylinder for cleaning can completely remove dirt, ordinary consumers will not disassemble or disassemble is not easy, so it cannot be widely promoted

[0005] (2) In the prior art, the cleaning agent can also be used to clean the dirt, but in fact the cleaning effect of the cleaning agent is not good, and the cleaning effect cannot be checked by naked eyes or equipment after cleaning

[0006] (3) Chinese invention patent application: a washing machine that is easy to clean, application number: 2019101348908. Although the patent application discloses that the inner cylinder can move relative to the outer cylinder, it usually requires people to manually pull out the inner cylinder or push the inner cylinder , the extension or retraction of the inner cylinder cannot be realized automatically through the control command

[0007] (4) Chinese invention patent application: a washing machine that is easy to clean, application number: 2019101348908. Although the patent application discloses that the inner cylinder can move relative to the outer cylinder, the locking mechanism between the inner and outer cylinders is too complicated and takes up space is too big

[0008] (5) Chinese invention patent application: an easy-to-clean washing machine, application number: 2019101348908. Although the patent application discloses that the inner cylinder can move relative to the outer cylinder, the two operate through the guiding mode of sliding parts and slide rails. The stability and smoothness need to be improved

[0009] (6) When the inner cylinder of the washing machine is pulled out from the outer cylinder, the two need to be free to separate, but when the inner cylinder returns to the outer cylinder after washing, it is necessary to ensure the locking relationship between the inner cylinder and the outer cylinder, otherwise the inner cylinder will rotate at a high speed , the inner cylinder may be displaced relative to the outer cylinder and affect the safe use of the washing machine
