[0017] In the working position, the second force-applying portion is further close to the first force-applying portion, so that the working portion moves before the first groove wall.

[0018] In one embodiment, the power-assisting component further includes a transmission portion connected between the first force-applying portion and the working portion, wherein the transmission portion passes through the second groove wall and extends to the working portion;

[0019] The power-assisting component is an integrated structure as a whole.

[0020] In one embodiment, the transmission portion extends obliquely upward from the first force-applying portion and is connected to the second groove wall at the highest point; the transmission portion passes through the second groove wall and bends obliquely downward to the working portion.

[0021] In one embodiment, the working portion is plate-shaped and gradually becomes thinner near the end.

[0022] This application also provides the following technical solutions:

[0038] See also Figure 1 and Figure 2 The present application provides a refrigerator door opening assist device 100, which is applied to a refrigerator and is mainly used to assist the refrigerator 200 in opening the door. By increasing the gap between the refrigerator door 10 and the refrigerator body 201, the force used to open the refrigerator 200 door is reduced, thereby improving the user experience of the refrigerator 200 and the applicability of the refrigerator 200, and increasing the service life of the refrigerator 200.

[0039] like Figures 1 to 5As shown, the refrigerator door opening assist device 100 includes a refrigerator door 10 and an assist component 20, wherein the refrigerator door 10 has a door seal 11 on the side facing the refrigerator body 201, and a joint seam 12 is formed between the door seal 11 and the refrigerator body 201. The refrigerator door 10 also has a first force-applying portion 13 for driving the door to open; the assist component 20 is movably mounted on the refrigerator door 10, and the assist component 20 has a second force-applying portion 21 that can be operated at one end along the motion transmission trend, and a working portion 22 with a convergent shape at the other end, and the working portion 22 is used to extend into the joint seam 12.

[0040] It needs to be explained that the traditional refrigerator door 10 is generally provided with a sealing device that can be sucked together with the refrigerator body 201 so that the refrigerator door 10 can be closed tightly. However, when the user is an elderly person, a child or a person with physical disabilities, it will be difficult to open the door. Therefore, the door opening is often assisted by adjusting the closing force of the guide rail, the magnetic force of the door seal and an external push rod. However, these modification methods and structural settings may affect the overall design of the refrigerator 200, and the structure is complex and unstable, which increases costs and is prone to failure. In the present application, a simple power-assisting component 20 is installed on the refrigerator door 10, and the two ends of the power-assisting component 20 are respectively set as a second force-applying part 21 and a working part 22 with a convergent shape. Before the user acts on the first force-applying part 13 on the refrigerator door 10, the second force-applying part 21 can be acted on, and the convergent part of the working part 22 can be driven to extend into the joint 12 between the door seal 11 and the refrigerator body 201, so as to create a larger gap, thereby weakening the suction force between the refrigerator door 10 and the refrigerator body 201, so as to reduce the force used by the user to open the door and ensure that the refrigerator door 10 can be opened smoothly.

[0041] like Figures 1 to 3 The top side of the refrigerator door 10 is provided with an operating groove 14, and the groove wall of the operating groove 14 serves as the first force-applying portion 13. The setting of the operating groove 14 facilitates the user to apply force to the refrigerator door 10 when opening it, that is, the user can directly pull the first force-applying portion 13 to open the refrigerator door 10.

[0042] Furthermore, the operating groove 14 has a first groove wall 141 and a second groove wall 142 that are arranged opposite to each other, wherein the first groove wall 141 serves as the first force applying portion 13 , and the second groove wall 142 is used for installing the power-assisting component 20 .

[0043] like Figure 4 and Figure 5As shown, the power-assisting component 20 is swingably mounted within the second groove wall 142, and the second force-applying portion 21 is plate-shaped and disposed vertically within the operating groove 14. Thus, when a user wishes to open the refrigerator door 10, they can directly apply force to the second force-applying portion 21 within the operating groove 14, causing the second force-applying portion 21 to swing the power-assisting component 20 within the second groove wall 142, thereby driving the working portion 22 to move between the door seal 11 and the refrigerator body 201, thereby facilitating door opening. Furthermore, the plate-shaped structure ensures that the second force-applying portion 21 always aligns with the first force-applying portion 13, making operation easier for the user.

[0044] Specifically, the second force-applying portion 21 and the working portion 22 are located on either side of the second groove wall 142, respectively. The assisting member 20 has a swing axis 23. Relative to the swing axis 23, the second force-applying portion 21 has a longer moment arm than the working portion 22. Thus, based on force analysis, a user can apply a relatively small force to the second force-applying portion 21 to move the working portion 22 into the joint 12, making the refrigerator door 10 easier to open. This makes it suitable for a variety of users, including the elderly and children.

[0045] Preferably, the working portion is plate-shaped and gradually becomes thinner near the end, and the thinned portion can extend into the joint seam 12 and help the refrigerator door to open.

[0046] Furthermore, the second force-applying portion 21 has a relative initial position and a working position, wherein, in the initial position, the second force-applying portion 21 is closer to the first groove wall 141 relative to the second groove wall 142, and does not affect the normal closing of the refrigerator door 10, and the second force-applying portion 21 and the second groove wall 142 are a force-applying area, and a motion compensation gap is left between the second force-applying portion 21 and the first groove wall 141; in the working position, the second force-applying portion 21 is further close to the first force-applying portion 13, so that the working portion 22 moves before the first groove wall 141. When the user wants to open the refrigerator door, the second force-applying portion 21 can be pulled in advance to move in the motion compensation gap, and the force applied to the second force-applying portion 21 can be transferred to the working portion, thereby helping the refrigerator door 10 to open.

[0047] For example, the assisting component 20 also includes a transmission part 24 connected between the first force-applying part 13 and the working part 22. The transmission part 24 passes through the second groove wall 142 and extends to the working part 22. It extends upward at an angle from the first force-applying part 13 and is connected to the second groove wall 142 at the highest part. At the same time, the transmission part 24 passes through the second groove wall 142 and bends downward at an angle until it reaches the working part 22. In this way, the force applied to the second force-applying part 21 can be transmitted to the working part 22, thereby assisting the opening of the refrigerator door 10.

[0048] Preferably, the power assist component is an integrated structure as a whole. The integrated structure can reduce the number of component connections, thereby increasing the stability of the structure, and the integrated structure has fewer production processes, which can reduce production costs.
