Description

Technical Field

[0001] The present application relates to the field of refrigerators, and in particular to a refrigerator and a method for improving foaming and deformation of a refrigerator body. Background Art

[0002] During winter factory production, due to the low temperature, the cabinets are assembled and foamed on the production line. When the cabinets are off the line after foaming, they will shrink when exposed to the cold in the room temperature environment. The shrinkage caused by the holding force of the foaming material will cause the overall size of the cabinet to become smaller, resulting in poor product assembly and restricted installation of structures such as drawers and partitions.

[0003] The current method is to use foam plugs to support the inner liner of the box to reduce the impact of deformation. However, when the refrigerator is cold, it shrinks inward, and the foam plugs provide limited support for the inward shrinkage of the inner liner. Summary of the Invention

[0013] Step S1: installing the connecting member on the back panel;

[0014] Step S2: connecting the back plate and the box body, and the inner container and the box body, so that the box body, the back plate and the inner container together form a foaming space, and the connecting piece divides the foaming space on the rear side of the box body;

[0034] See also Figures 1 to 2 As shown, the back plate 1 and the inner liner 4 are both installed on the box body 3. The box body 3 includes a bottom plate, a top plate and two side plates. The top plate, the bottom plate and the two side plates are all connected to the back plate 1. The two side plates are respectively arranged on both sides of the inner liner 4. The top plate is arranged above the inner liner 4, the bottom plate is arranged below the inner liner 4, the back plate 1 is arranged behind the inner liner 4, and the two side plates are connected to the two sides of the inner liner 4. The box body 3 and the back plate 1 are semi-enclosed on the outside of the inner liner 4. A "U"-shaped foaming space 5 is formed between the box body 3, the back plate 1 and the inner liner 4. The foaming space 5 is used to inject a foaming agent. The foaming agent is injected from the top of the box body 3. After the foaming agent is injected, the top plate is installed and placed at a set temperature for foaming.

[0035] The box body 3 is connected with a connector 2, which divides the foaming space 5 into several sections. The continuity of the foaming agent forming a solid after thermal foaming is destroyed, and the degree of deformation during cold contraction is also reduced.

[0036] The connecting member 2 includes a connecting portion 21 and a supporting portion 22. Both ends of the connecting portion 21 are connected to the back plate 1, one end of the supporting portion 22 is connected to the middle of the connecting portion 21, and the other end of the supporting portion 22 is against the inner tank 4, thereby forming a division of the foaming space 5.

[0037] The connecting piece 2 is provided on the back panel 1, and its cutting off of the foaming space 5 is also concentrated on the rear side of the box body 3. Part of the clamping force of the foaming material shrinking when it is cold is shared by the dividing part of the connecting piece 2, and part is shared by the foaming material. Therefore, the connecting piece 2 will be deformed first under pressure, thereby reducing the shrinkage force on the front side of the box body 3, allowing the shrinkage to occur first near the back panel 1, and then reducing the deformation of the front side of the box body 3. Generally, drawers, partitions and other structures are installed on the front side of the box body 3. The smaller deformation of the front side can ensure that the installation of drawers, partitions and other structures is not restricted.

[0038] The method for improving the foaming deformation of the box body 3 includes:

[0039] Step S1: Install the connector 2 on the back panel 1;

[0040] Step S2: Install the back panel 1 onto the box body 3;

[0041] Step S3: Install the inner liner 4 onto the box body 3, forming a foaming space 5 between the inner liner 4 and the box body 3, and the connecting piece 2 divides the foaming space 5 on the rear side of the box body 3;

[0042] Step S4: injecting a foaming agent into the foaming space 5 to perform thermal foaming and cooling.

[0043] See also Figures 3 to 5 As shown, one end of the back panel 1 is bent to form a bent portion, and the back panel 1 is provided with a mounting channel 12 in a vertical direction starting from the other end. The mounting channel 12 extends to the bent portion. The mounting channel 12 is an open structure on the other end of the back panel 1, that is, an opening is formed, and the back panel 1 on both sides of the mounting channel 12 forms an edge portion 14.

[0044] Furthermore, both ends of the connecting portion 21 are provided with mounting grooves 211, and the edge portion 14 can be slidably embedded in the mounting grooves 211. The connecting member 2 can be slidably installed along the edge portion 14 to abut against the bending portion 11, and a sealing member is used to seal the open structure 13, thereby fixing the connecting member 2.

[0045] For further information, see Figure 6 As shown, both ends of the connecting portion 21 located on the inner side of the back plate 1 are tilted toward the inner container 4 to form tilted portions 212 to facilitate the alignment and matching of the edge portion 14 and the mounting groove 211 .

[0046] The specific steps of installing the connector 2 on the back panel 1 include:

[0047] Step S1.1: bending one end of the back plate 1 to form a bent portion;

[0048] Step S1.2: A mounting channel 12 is formed vertically on the back panel 1 , wherein the mounting channel 12 is an open structure 13 at the other end of the back panel 1 ;

[0049] Step S1.3: Install the connector 2 along the installation channel 12 from one end of the back panel 1 .

[0050] Step S1.4: After the connector 2 is installed in the installation channel 12 , the open structure 13 is sealed with a sealing member.
