Description

Technical Field

[0001] The utility model belongs to the technical field of washing machines, in particular to an inner cover of a washing machine and a washing machine. Background Art

[0002] A washing machine is a household appliance used for washing clothes, which mainly includes a main body, an outer barrel, an inner barrel, a transmission and a control module. Conventionally, an outer barrel cover is installed on the upper end of the outer barrel of the washing machine, and a clothing delivery port is provided on the outer barrel cover, and an inner cover is provided at the delivery port. When delivering clothes, the inner cover is opened, and the clothes to be washed are delivered into the inner barrel from the delivery port. When washing, the inner cover is locked to close the outer barrel cover to prevent the clothes from being thrown out and the water from splashing out.

[0003] The inner cover and the outer barrel cover are generally connected in a snap-fit ​​form. For example, in a washing machine with a drying function disclosed in application number CN2016212242190, the rear end of the inner cover is hinged to the barrel cover, and the front end of the inner cover is provided with a handle, and the handle is provided with a hook. The barrel body is provided with a buckle slot, and the hook is buckled into the buckle slot. In this technical solution, the handle and the inner cover are rotatably matched, and a torsion spring is provided between the two. This is a conventional technical means in the field. The user needs to pull up the handle to disengage the hook from the buckle slot, and the corresponding torsion spring is twisted and generates a rebound force. After the hook is disengaged from the buckle slot, the torsion spring rebounds, and the inner cover is suddenly flipped upward when switching from a locked state to an unlocked state. The user experience is poor, and this connection method is relatively fragile, and the connection structure is easily damaged due to improper operation. Utility Model Content
