Problems solved by technology

[0004] However, when the refrigerator is powered off, the door opening and closing device cannot automatically control the opening and closing of the door body, and the user needs to manually open and close the door.
When opening and closing the door manually, the torque in the opening and closing device will be transmitted in reverse (that is, from the door body to the motor), and there will be a large resistance during the transmission process, which will cause manual opening and closing of the door to be laborious and affect the user experience
Moreover, when the door is manually closed, it will cause resistance to the door seal, and the door cannot be closed tightly, which will also affect the user experience

Embodiment Construction

[0038] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

[0039] The present disclosure provides a door opening and closing device. When the door opening and closing device is in a working state, when the door is automatically opened and closed, the driving structure can transmit torque to the driven structure through the intermediate transmission structure, so as to realize the automatic opening and closing of the door; when the door is opened and closed man...

Abstract

The present disclosure relates to a door opening and closing device and a refrigerator. The refrigerator includes a motor and a door body. The door opening and closing device includes a driving structure connected to the motor drive, an intermediate drive structure, and a driven structure connected to the door body. The intermediate drive structure includes a sliding structure. The door opening and closing device is in the working state, the driving structure is connected with the intermediate transmission structure, and the intermediate transmission structure is also connected with the driven structure; The structure transmits torque to the driven structure, and the slip mechanism is such that the intermediate transmission structure restricts the transmission of torque from the driven structure to the drive structure. In the door opening and closing device, when it is in the working state, the user can not only realize the automatic opening and closing of the door through the motor, but also realize the manual opening and closing of the door with a small force, so as to improve the user experience, and when the door is manually closed, it can also be more It can realize the suction and closing of the door seal well, and improve the user experience.

Description

technical field [0001] The present disclosure relates to the technical field of electrical equipment, and in particular, to a door opening and closing device and a refrigerator. Background technique [0002] With the improvement of people's living standards, automatic electrical equipment is gradually favored by people. For example, the electrical equipment is a refrigerator, and a door opening and closing device is generally provided in the refrigerator to realize automatic opening and closing of the door, so as to facilitate the use of users. [0003] When the user's hands are inconvenient to open the door of the refrigerator, the user can automatically open and close the door by means of voice recognition, gesture recognition or tactile recognition. When the door is automatically opened and closed, the torque in the door opening and closing device is transmitted forward (that is, transmitted by the motor to the door body), so as to automatically control the opening or clo...
