Description

Washing machine door opening mechanism and washing machine

Technical Field

The invention relates to the technical field of washing machines, in particular to a washing machine door opening mechanism and a washing machine.

Background

Most washing machines in the market need a user to manually and mechanically open a door before use, but the door is inconvenient to open when the user holds clothes and washing tools with both hands; if a user can not take out the clothes in time after the clothes hanger is used, the clothes are easy to breed bacteria and emit peculiar smell in a closed environment.

The mechanisms for automatic door opening in the prior patents are mainly divided into two categories: one type is an electromagnet type lock hook, and the door opening and closing actions are realized by means of electromagnetic adsorption force which is generated and disappeared when the electromagnet is powered on and powered off. One is that the control mechanism is installed at the hinge of the washing machine door body, and the door plate rotating shaft of the washing machine is driven to rotate by the rotation of the driving motor crankshaft. However, the two designs have respective disadvantages, and the first design still needs to turn on or off the electromagnet by pressing the electromagnetic switch by the user, so that the problem of inconvenience when the user holds the object by both hands cannot be solved. The crankshaft of the driving motor of the second type of patent is easy to generate eccentric wear when moving relative to the door panel rotating shaft, and the crankshaft and the door panel rotating shaft are worn after being used for a long time.
