Problems solved by technology

[0002] Today, it is the general trend for home appliances to develop towards intelligence and humanization. Traditional refrigerators that manually open and close refrigerator doors and refrigerator drawers can no longer meet the needs of consumers.
[0003] With the continuous progress of society and the development of science and technology, smart refrigerators that automatically open refrigerator doors and refrigerator drawers appear on the market. Due to unreasonable structural design, the automatic door and drawer opening devices are large in size, high in process requirements, and high in production costs. , it is not stable enough when opening and closing the refrigerator door and refrigerator drawer, the noise is loud, and it is not humanized and intelligent enough

Abstract

The invention relates to an automatic door and drawer opening device used for a refrigerator. The automatic door and drawer opening device comprises a shell and an upper cover. A drive assembly, a push rod, a guide rail, a reset spring, a microswitch and a microswitch stirring rod are arranged in the shell. One end of the reset spring is connected to the shell, and the other end of the reset spring is connected to the push rod. A gear shaft of a tooth-missing gear is sleeved with the tail end of the microswitch stirring rod. An arc-shaped protrusion is arranged in the tail end of the microswitch stirring rod. An arc-shaped groove is formed in the upper end of the gear shaft of the tooth-missing gear. The start end face of the microswitch stirring rod abuts against the side face of an elastic piece of the microswitch. The automatic door and drawer opening device is reasonable in structural design, the installation space is saved, the process requirement is lowered, the production cost is reduced, and the work reliability and stability are improved; and the tooth-missing gear is arranged, when a door or drawer of the refrigerator is pushed open, the push rod ingeniously resets through the reset spring, and therefore the push rod does not need to be driven by a motor to reset, control is more flexible, intelligent and user-friendly, and noise generated when the device works is greatly reduced.
