Automatic door and drawer opening device used for refrigerator

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.
