[0034] Please refer to Figures 1-8 , this utility model provides a refrigerator 100, which optimizes the structure of the driving assembly 20 and protects the driving member 22 from the influence of the foaming process through the housing 21.

[0035] The refrigerator 100 includes a cabinet 10, a door (not shown in the figure), and a driving assembly 20. The cabinet 10 is provided with a refrigerating chamber and a chamber 11. The chamber 11 is located below the refrigerating chamber and is partitioned from the refrigerating chamber. The door is rotatably connected to the cabinet 10. The driving assembly 20 is installed in the chamber 11. The driving assembly 20 includes a housing 21 and a driving member 22. The housing 21 is connected to the cabinet 10. The driving member 22 is installed in the housing 21 and is connected to the cabinet 10. One end of the driving member 22 passes through the side wall of the housing 21 and extends to the outside of the chamber 11 and abuts against the door. In this way, the chamber 11 is located below the refrigerating chamber. Therefore, foaming material needs to be filled in the chamber 11 and the refrigerating chamber is insulated by the foaming process. The driving member 22 abuts against the door. Therefore, the extension of the driving member 22 can push the door to open automatically. The driving member 22 is located inside the housing 21. The housing 21 can protect the driving member 22 and prevent the structure of the driving member 22, such as the motor terminal and other structures, from being damaged when foaming is carried out in the chamber 11.

[0036] Further, the driving member 22 includes a driving source 221 and a telescopic rod 222. The driving source 221 can drive the telescopic rod 222 to extend towards the door, and the telescopic rod 222 is configured to be retracted in response to the closing of the door. In this way, the structure of the telescopic rod 222 is simple and the cost is low. Moreover, the extending and retracting directions of the telescopic rod 222 are on the same axis. The thrust applied to the door by the telescopic rod 222 is more consistent, and more loads can be borne on this straight line.

[0037] It can be understood that in other embodiments, the driving member 22 can also be set as a driving source 221 and a rotating rod. The driving source 221 drives the rotating rod to rotate, and the door is driven to open or close by the rotating rod, which can also realize the automatic opening and closing of the refrigerator 100, and is not limited to the above-mentioned telescopic rod 222.

[0038] Furthermore, an abutting head 223 is provided at one end of the telescopic rod 222 away from the driving source 221. The diameter of the abutting head 223 is larger than that of the telescopic rod 222. In this way, the abutting head 223 increases the abutting area between the telescopic rod 222 and the door, reduces the pressure per unit area, improves the abutting stability, and avoids damaging the door caused by the long-term use of the telescopic rod 222.

[0039] Specifically, in this embodiment, the abutting head 223 is made of a soft material, such as rubber material, to increase the friction force and further reduce the deformation and damage caused by abutting against the door.

[0040] The cabinet 10 includes a main body 13 and a base 14. The base 14 is connected to the main body 13, and the drive assembly 20 is connected to the base 14. In this way, the base 14 and the main body 13 can be processed separately to reduce the processing difficulty. During assembly, the drive assembly 20 can also be assembled with the base 14 first, reducing the assembly difficulty and minimizing the impact on the main body 13, thereby improving the structural durability of the refrigerator 100.

[0041] Further, an installation groove is formed on the base 14, and at least a part of the driving member 22 is disposed in the installation groove. In this way, the installation groove can accommodate the driving member 22, facilitating the installation of the driving member 22 and providing protection for the driving member 22.

[0042] In this embodiment, the bottom of the base 14 protrudes downward to form a convex block, and the installation groove is formed in the convex block. That is, a part of the driving member 22 can be disposed on the lower side of the bottom wall surface of the base 14, thereby reducing the occupation of the space in the chamber 11.

[0043] Of course, in other embodiments, the driving member 22 can also be directly connected to the base 14, not limited to the form of providing an installation groove.

[0044] Further, one side of the base 14 close to the door has a flange 141. A first through hole 1411 is formed on the flange 141, and a second through hole is formed on the housing 21. The first through hole 1411 and the second through hole are coaxially arranged and allow the driving member 22 to extend therethrough. In this way, the first through hole 1411 and the second through hole allow the telescopic rod 222 on the driving member 22 to extend therethrough.

[0045] A third through hole 212 is further formed on one side of the housing 21 away from the second through hole. The third through hole 212 is used for structures such as wires connected to the driving member 22 to pass through and extend to other electrical components.

[0046] Specifically, in this embodiment, a wire-passing column protrudes from one side of the housing 21 away from the second through hole. The third through hole 212 is formed at the axial position of the wire-passing column, and the wire-passing column can provide protection for the wire.

[0047] The chamber 11 includes a first chamber 111 and a second chamber 112. The first chamber 111 is formed in the main body 13. A part of the base 14 and the bottom wall of the main body 13 are spaced apart and cooperate with the main body 13 to form the second chamber 112. The drive assembly 20 is disposed in the second chamber 112. In this way, there are other electrical components in the first chamber 111 and foaming material will be filled therein, while the drive assembly 20 is installed in the second chamber 112, which can reduce the mutual interference and influence between the two.

[0048] The refrigerator 100 further includes an inner liner box 30. The inner liner box 30 is connected to the base 14, and the bottom of the inner liner box 30 abuts against the housing 21. After the inner liner box 30 abuts against the housing 21, the positions of both are more stable. The inner liner box 30 can further block the influence of the foaming layer in the first chamber 111 on the driving assembly 20.

[0049] Preferably, an opening 131 is provided at the bottom of the main body 13. The opening 131 communicates with the first chamber 111 and the second chamber 112. The inner liner box 30 has a box body 31 and a cover body 32. The box body 31 has a box opening, and the edge of the box opening corresponds to the opening 131 and abuts against the outer bottom wall of the main body 13. The cover body 32 is covered at the opening 131 and is hermetically connected to the inner bottom wall of the main body 13. In this way, the cover body 32 seals the box body 31 and at the same time forms a cooperation with the inner bottom wall of the main body 13. When the driving assembly 20 needs to be disassembled and repaired, it is not necessary to tilt or lay the refrigerator 100 flat on the ground (in the prior art, usually the driving assembly 20 is installed by opening an installation opening at the bottom of the refrigerator 100, and the cover plate and bolts on the installation opening are installed from bottom to top). It can be directly operated through the chamber 11. After removing the cover body 32, the box body 31 and the driving assembly 20 under the box body 31 can be maintained later.

[0050] Further, a foaming layer is provided in the inner liner box 30, and along the vertical direction, the thickness of the foaming layer is at least 53 mm. In this way, the heat insulation effect of the inner liner box 30 is ensured. It can not only provide sufficient cold preservation effect for the refrigerating chamber, but also prevent the heat in the driving assembly 20 from overflowing upward and affecting the temperature in the refrigerating chamber.

[0051] It should be noted that the vertical direction refers to the direction of gravity when the refrigerator is placed normally, that is, the direction perpendicular to the ground. In other embodiments, the foaming layer in the inner liner box 30 can be not only greater than 53 mm vertically, but also greater than 53 mm in horizontal width.

[0052] Compared with the prior art, the present utility model protects the driving part 22 by setting the housing 21, preventing the foaming material from squeezing onto the terminals and other structures of the driving part 22 and causing damage to the driving part 22 when foaming the chamber 11 on the lower side of the refrigerating chamber. And further optimizing the internal structure of the box body 10, integrating the driving assembly 20 and the inner liner box 30 on the base 14, thereby improving the cold preservation effect of the refrigerator 100 and the installation stability of the driving assembly 20.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
