Problems solved by technology

However, this structure does not take into account the influence of factors such as speed changes and door opening time during the drawer opening process.
Moreover, during the opening process of the drawer, the driving pins 20a, 20b, and 20c need to be in contact with the connecting plate 16 successively, and there is a discontinuous situation during the cooperation process, resulting in an uneven opening process of the drawer.

Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0025] Firstly, through experiments and combined with ergonomics, the present invention measures and calculates the opening speed curve and force curve that conform to the habit of the user when opening the drawer or door, and then obtains the output of the drawer or door opening device through theoretical calculation. As mentioned in the background technology section, the opening process of the drawer or door body is divided into the following three stages in the experiment: the first stage mainly overcomes the suction force of the door seal and the automatic closing locking force of the drawer or door body; the sec...

Abstract

The invention discloses a drawer or door opening device and a refrigerator with the drawer or door opening device. The drawer or door opening device comprises a drive source component, a pushing piece and a transmission body connected between the drive source component and the pushing piece. The transmission body comprises a conjugated gear set. The drive source component provides input torque for the conjugated gear set. The conjugated gear set is configured to convert the input torque into output torque which changes continuously and provide the output torque for the pushing piece.

Description

technical field [0001] The invention relates to a drawer or door opening device and a refrigerator with the opening device. Background technique [0002] At present, the medium and high-end refrigerators on the market are relatively large, and the drawers or doors, the weight of the loads, and the door seals of the doors or drawer-type doors have relatively large suction. More and more users report that the drawers or doors of the refrigerators are not easy to open. . For this problem, electric opener has occurred. [0003] In the process of opening a drawer or door, it is necessary to overcome the suction force of the door seal, the locking force of the slide rail, or the self-closing force and friction of the door body. Generally, it is mainly divided into three stages: the first stage mainly overcomes Door seal suction, automatic closing locking force and friction; the second stage mainly overcomes the locking force of automatic closing (such as spring tension or the se...
