Actuating mechanism with automatic door opening and closing function

Abstract

The invention discloses an actuating mechanism with an automatic door opening and closing function. The actuating mechanism comprises a motor, a transmission structure, a push rod, a connector and a door holder, and the motor drives the push rod to move through the transmission structure; the connector is mounted at one end of the push rod; and after the connector is inserted into the door holder, when the connector is located at a third position, the door holder prevents the connector from moving. According to the actuating mechanism with the automatic door opening and closing function, the executing mechanism is independent of the door lock of a household appliance and can be universally used for the household appliance with different door locks or without the door locks, such as a dish washing machine, a washing machine, a refrigerator and a microwave oven. Under the control of a software system of the household appliance, automatic door opening and closing of the household appliance can be achieved, user experience is improved, the situation that a door is not closed in place or the household appliance is damaged due to misoperation of a user is avoided, and the functions of hand pinching prevention and child lock are achieved.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to an actuator with the function of automatically opening and closing doors. Background technique [0002] With the development of the economy, people have higher and higher requirements for the automation of household appliances, but the development of automation technology for opening and closing doors of household appliances is relatively slow. A small number of manufacturers have installed automatic door opening and closing devices, and there are also some problems. For example, the door can only be opened automatically, but the automatic door closing function cannot be realized. There are also some technologies that realize the automatic door opening and closing function, such as the Chinese patent whose publication number is CN106761149, which discloses a kind of executive mechanism with automatic door opening and closing function, drives the reduction gear mechan...

AI Technical Summary

Problems solved by technology

This patent directly combines the automatic door opening and closing device with the door lock, and the structure is very complicated. However, there are many types of household appliances and the door lock structures are different. If each type of door lock is automatically upgraded, the design cost is high and may affect other functions

The technical solution of this patent also does not take into account the obstruction of foreign objects or the problem of user's hand pinching during the closing process
