[0002] The washing machine top cover assembly is a component used to protect the internal components of the washing machine and play a decorative role. It can also serve as an operating table for users.

[0003] An existing Chinese patent (publication number CN214992495U) discloses a washing machine top cover assembly, in which the limit support block and the limit support hole are interlocked by pushing the reinforcing plate as a whole so that the limit support block is inserted into the limit support hole. The assembly is easy and solves the problem that the all-plastic top cover is large in size and insufficient in strength, which leads to deformation of the top cover and the risk of damage to the entire machine. The installation structure ensures the stability of the installation and is convenient.

[0004] In the above technical solution, a reinforcing plate is provided to strengthen the strength of the top cover of the washing machine. However, in actual application, the reinforcing plate will be worn out due to the vibration generated during the operation of the washing machine. In order to ensure the strength of the top cover, the reinforcing plate needs to be replaced regularly. The reinforcing plate in the above patent is first positioned by a snap-fit ​​part, and then fixed in a fixing groove by a fixing part such as a screw. When replacing the reinforcing plate, whether it is disassembling or fixing the reinforcing plate, the operation steps are relatively cumbersome. Utility Model Content
