Automatic door opening and closing device of dual-motor refrigerator

Abstract

The invention discloses an automatic door opening and closing device of a dual-motor refrigerator, and relates to the technical field of refrigerator manufacturing. The automatic door opening and closing device of the dual-motor refrigerator comprises a box body and a box door. The box body and the box door are rotationally connected through a hinge. The box body is provided with a telescopic device. A circular-arc-shaped rack is fixedly connected with one end of the hinge. The box door is provided with an intermittent gear connected with a vertically-arranged motor. The telescopic device comprises a base fixedly connected with a motor. The motor is connected with a threaded rod. A guide sleeve is arranged on the circumferential side face of the threaded rod through threads in a cooperation manner. The guide sleeve is in sliding fit with the base through a sliding block. A push rod is fixedly connected with one side face of the sliding block. According to the automatic door opening andclosing device of the dual-motor refrigerator, the circular-arc-shaped rack and the intermittent gear which is matched with the circular-arc-shaped rack and is arranged on the box door are arranged;because the telescopic device is arranged on the box body, the problem that an existing refrigerator cannot carry out automatic door opening and closing, and thereby being not convenient to use is solved; and because of thread fit between the guide sleeve and the threaded rod, and sliding fit between the sliding block and a channel, the process of the push rod to push the box door is more stable,generated noise is lowered, and generated vibration is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerator manufacturing, and in particular relates to an automatic door opening and closing device for a double-motor refrigerator. Background technique [0002] With the development of intelligent home appliances, whether it is large appliances such as refrigerators, washing machines, air conditioners, and color TVs, or small appliances such as air purifiers and kitchen and bathroom supplies, they all advocate technology and intelligence. The concept matches the upgrading needs of Chinese consumers. Intelligentization is already a trend in the development of home appliances; It is very inconvenient to put the items in the refrigerator, and then open the refrigerator; when the refrigerator is equipped with an automatic door opening device; or the refrigerator door is opened by voice control, people can easily put the items in both hands into the refrigerator ; Simplify the operation process, improve t...
