Door opening and closing device and refrigerator with same

Abstract

The invention discloses a door opening and closing device and a refrigerator with the same, and relates to the technical field of refrigerators. The refrigerator comprises a box body. A door body is installed at an opening of a cavity of the box body through a hinge. A transmission mechanism is installed on one side of the door body. The transmission mechanism comprises a motor, a lead screw, a bearing pedestal, a clutch, a slider, a driving block, a guide rod and fixed bases. The two ends of the lead screw are rotationally installed on the bearing pedestal and the driving block correspondingly. The motor is in transmission connection with the input end of the clutch through an output shaft. The two fixed bases are fixed to one side of the lead screw. The guide rod is installed between thetwo fixed bases. The slider is slidingly installed on the guide rod. One side face of the slider makes contact with one side face of the driving block. The slider is connected with the door body through a connecting rod. Through the cooperation of the installed driving block and the slider, the door body can be opened manually or automatically, and different use requirements are met.

Description

Technical field [0001] The invention belongs to the technical field of refrigerators, and particularly relates to a door opening and closing device and a refrigerator applying the same.

Problems solved by technology

In the daily use process, after taking the items, we often forget to close the door of the refrigerator, or the door of the refrigerator is not closed tightly, which affects the preservation of the items in the refrigerator

[0003] Currently on the market, most refrigerator doors are still opened and closed manually, which is very inconvenient when users hold items in both hands

Some home appliance manufacturers have launched refrigerators that can open the door semi-automatically through touch, human body induction, voice, and buttons. However, the doors of these refrigerators cannot be automatically opened to the desired angle, and there is no automatic door closing function, which makes the user experience poor.

The existing automatic door opening and closing schemes are mostly used in conjunction with multiple modules, and the cost is relatively expensive, so it is difficult to be widely used
