[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] Combination Figures 1 to 6 As shown, an embodiment of the present disclosure provides a back panel for a refrigerator, including a first plate body 100, a second plate body 200 and a connecting plate 300, wherein the first plate body 100 and the second plate body 200 both extend vertically; the connecting plate 300 extends vertically, including a first connecting end 310 and a second connecting end 320 arranged opposite to each other, the first connecting end 310 is plugged into the first plate body 100, and the second connecting end 320 is connected to the second plate body 200.

[0045] Optionally, the box body of the refrigerator includes at least a top plate, a bottom plate, a side plate and a back plate for the refrigerator, an inner liner is provided inside the box body, and a foaming layer is provided between the inner liner and the box body. After the foaming is completed, the foaming layer will shrink due to the decrease in temperature, especially in winter, the shrinkage is more serious, and the resulting shrinkage force will pull the box body to shrink the box body. In order to improve the serious deformation caused by the shrinkage of the box body, thereby affecting the assembly of structural parts (such as drawers, shelves, etc.) inside the inner liner. Among them, when the foaming layer shrinks, it will force the back plate or the side plate to be concave toward the inside of the box body, causing deformation in the vertical direction.

[0046] The back plate for the refrigerator includes a first plate body 100, a second plate body 200 and a connecting plate 300. By setting the back plate for the refrigerator as the first plate body 100 and the second plate body 200 connected by the connecting plate 300, wherein the first connecting end 310 of the connecting plate 300 is plugged with the first plate body 100, and the second connecting end 320 of the connecting plate 300 is connected with the second plate body 200, the shrinkage stress of the box can be concentrated at the position where the first plate body 100 and the second plate body 200 are connected, that is, the connecting plate 300, during the foaming and cooling process of the foaming layer. In other words, the shrinkage force generated when the box shrinks can first act on the position where the first plate body 100 and the second plate body 200 forming the back plate are connected, that is, the connecting plate 300 is first displaced or deformed, so that the shrinkage force of the front part of the box can be reduced, thereby reducing the deformation amount of the front side of the box, and then reducing the shrinkage deformation amount of the front part of the box as much as possible, and ensuring the assembly accuracy of the internal structural parts of the box.

[0047] Optionally, the second connection end 320 is fixedly connected to the second board body 200 , or the second connection end 320 is plugged into the second board body 200 .

[0048] Optionally, the first plate body 100 and the second plate body 200 have the same structure so that the stresses borne by the first connection end 310 and the second connection end 320 are as similar as possible to ensure that the deformation amounts produced by the connection plate 300 near the first connection end 310 and near the second connection end 320 are the same.

[0049] Furthermore, by constructing the connecting plate 300, the first plate body 100 and the second plate body 200 to extend vertically, the deformation direction of the back plate can be followed, so that the back plate used for the refrigerator can better adapt to the deformation, thereby improving the overall strength and stability of the back plate used for the refrigerator.

[0050] By adopting the back plate for refrigerators provided by the embodiment of the present disclosure, by setting the back plate for refrigerators as a first plate body and a second plate body connected by a connecting plate, wherein the first connecting end of the connecting plate is plugged into the first plate body, and the second connecting end of the connecting plate is plugged into the second plate body, the shrinkage stress of the box body can be concentrated at the connection between the connecting plate and the first plate body and the connection between the connecting plate and the second plate body during the foaming and cooling process of the foaming layer. That is to say, since the first plate body and the second plate body are plugged into the connecting plate, the shrinkage force generated when the box body of the refrigerator shrinks can first act on the connection position between the first plate body and the second plate body of the forming plate, that is, the connecting plate is first displaced or deformed, so that the shrinkage force of the front part of the box body can be reduced, thereby reducing the deformation amount of the front side of the box body, and then reducing the shrinkage deformation amount of the front part of the box body as much as possible, and ensuring the assembly accuracy of the internal structural parts of the box body. At the same time, after the foaming layer is completed, it shrinks due to the decrease in temperature, forcing the back panel to be concave toward the inside of the refrigerator and deform vertically; by constructing the connecting plate, the first plate body and the second plate body to extend vertically, the direction of deformation of the back panel can be followed, so that the back panel can better adapt to the deformation and improve the overall strength and stability of the back panel.

[0051] Optionally, the first connection end 310 is provided with a first slot 311 extending vertically, and the first side end 110 of the first plate body 100 is inserted into the first slot 311; the second connection end 320 is provided with a second slot 321 extending vertically, and the second side end 210 of the second plate body 200 is inserted into the second slot 321.

[0052] In this way, by inserting the first side end 110 into the first slot 311, the connecting plate 300 can be stably connected and quickly installed with the first plate body 100; by inserting the second side end 210 into the second slot 321, the connecting plate 300 can be stably connected and quickly installed with the second plate body 200.

[0053] Optionally, the first slot 311 includes a first slot wall 3111 and a second slot wall 3113 arranged opposite to each other; a first guide section 3112 is provided at the end of the first slot wall 3111 close to the first slot, and the first guide section 3112 is inclined in a direction away from the second slot wall 3113; or, a second guide section 3114 is provided at the end of the second slot wall 3113 close to the first slot, and the second guide section 3114 is inclined in a direction away from the first slot wall 3111.

[0054] The first notch of the first insertion slot 311 is arranged toward the first plate body 100. By providing the first guide section 3112 or the second guide section 3114, an expanded first notch can be formed between the first slot wall 3111 and the second slot wall 3113, thereby improving the convenience of inserting the first plate body 100 into the first insertion slot 311; at the same time, the first guide section 3112 or the second guide section 3114 can guide the first side end 110 of the first plate body 100, so that the first side end 110 can be smoothly inserted into the first insertion slot 311.

[0055] Optionally, the second slot 321 includes a third slot wall 3211 and a fourth slot wall 3213 arranged opposite to each other; a third guide section 3212 is provided at the end of the third slot wall 3211 close to the second slot, and the third guide section 3212 is inclined in a direction away from the fourth slot wall 3213; or, a fourth guide section 3214 is provided at the end of the fourth slot wall 3213 close to the second slot, and the fourth guide section 3214 is inclined in a direction away from the third slot wall 3211.

[0056] The first notch of the second insertion slot 321 is arranged toward the second plate body 200. By providing the third guide segment 3212 or the fourth guide segment 3214, an expanded second notch can be formed between the third slot wall 3211 and the fourth slot wall 3213, thereby improving the convenience of inserting the second plate body 200 into the second insertion slot 321; at the same time, the third guide segment 3212 or the fourth guide segment 3214 can guide the second side end 210 of the second plate body 200, so that the second side end 210 can be smoothly inserted into the second insertion slot 321.

[0057] Optionally, the first side end 110 is provided with a first elastic shrinkage member, and the first elastic shrinkage member is made of rubber material; and / or, the second side end 210 is provided with a second elastic shrinkage member, and the second elastic shrinkage member is made of rubber material.

[0058] When the foaming layer contracts due to cooling or at low temperatures, it can drive the first plate body 100 to move in the first slot 311 toward the bottom wall of the first slot 311 to squeeze and compress the first elastic shrinkage member; and it can also drive the second plate body 200 to move in the second slot 321 toward the bottom wall of the second slot 321 to squeeze and compress the second elastic shrinkage member, thereby achieving the contraction of the back panel of the refrigerator; by using rubber material for both the first elastic shrinkage member and the second elastic shrinkage member, a buffering effect can be provided, thereby improving the stability of the back panel of the refrigerator when it shrinks.

[0059] Optionally, a first shrinkage gap is provided between the first side end 110 and the first bottom wall of the first slot 311 ; and / or a second shrinkage gap is provided between the second side end 210 and the first bottom wall of the second slot 321 .

[0060] When the foaming layer contracts when it cools down or contracts at low temperatures, it can drive the first plate body 100 to move in the first slot 311 toward the bottom wall of the first slot 311 to shrink into the first shrinkage gap, thereby achieving the shrinkage of the back panel of the refrigerator; or, it can also drive the second plate body 200 to move in the second slot 321 toward the bottom wall of the second slot 321 to shrink into the second shrinkage gap, thereby achieving the shrinkage of the back panel of the refrigerator.

[0061] Alternatively, the connection plate 300 may be configured in a flat plate shape.

[0062] Optionally, combined Figures 4 to 6 As shown, the connecting plate 300 is recessed from one surface to the other surface to form a contraction groove 330 extending vertically.

[0063] In this way, when the foaming layer contracts when cooled or in a low-temperature environment, stress acts on the connecting plate 300, which can cause the shrinkage groove 330 to deform and shrink, thereby achieving better distribution and dispersion of stress, reducing stress concentration, and further improving the stability and safety of the back plate shrinkage for the refrigerator.

[0064] Optionally, the cross section of the contraction groove 330 is V-shaped or U-shaped.

[0065] Optionally, the contraction groove 330 includes a fifth groove wall 331 and a sixth groove wall 332 connected to each other, wherein the fifth groove wall 331 and the sixth groove wall 332 are connected in an arc shape.

[0066] By connecting the fifth groove wall 331 and the sixth groove wall 332 in an arc shape, a smooth transition connection can be achieved between the two, thereby reducing stress concentration. The reduction in stress concentration helps to delay the fatigue process of the connecting plate 300, extend the service life of the shrinkage groove 330, i.e., the connecting plate 300, and improve the bearing capacity of the connecting plate 300, thereby improving the stability and safety of the shrinkage groove 330.

[0067] Optionally, one contraction groove 330 is provided from the first connection end 310 to the second connection end 320 ; or, a plurality of contraction grooves 330 are provided in sequence from the first connection end 310 to the second connection end 320 .

[0068] A shrinkage groove 330 may be provided from the first connection end 310 to the second connection end 320 to achieve shrinkage of the back panel of the refrigerator, reduce the deformation of the front side of the cabinet, and thereby minimize the shrinkage deformation of the front of the cabinet.

[0069] Alternatively, the stress on the connecting plate 300 can be shared and dispersed through the shrinkage function of multiple shrinkage grooves 330, so as to distribute the load in the overall area of ​​the connecting plate 300 and reduce stress concentration, thereby improving the bearing capacity of the connecting plate 300 when the connecting plate 300 shrinks, thereby improving the safety and structural stability of the back plate used for the refrigerator.

[0070] Optionally, combined Figure 7 , Figure 8 As shown, when the connection plate 300 is provided with a shrinkage groove 330, the connection plate 300 can be integrally connected with the first plate body 100 and the second plate body 200 to improve the safety and structural stability of the back plate used for the refrigerator.

[0071] An embodiment of the present disclosure provides a refrigerator, comprising the back plate for a refrigerator as described above.

[0072] The refrigerator provided by the embodiment of the present disclosure includes the back plate for the refrigerator as described above, and the back plate of the refrigerator is set as a first plate body and a second plate body connected by a connecting plate, wherein the first connecting end of the connecting plate is plugged into the first plate body, and the second connecting end of the connecting plate is plugged into the second plate body, so that the shrinkage stress of the box body can be concentrated on the connection between the first plate body and the second plate body, that is, the connecting plate, during the foaming and cooling process of the foaming layer. That is to say, since the first plate body and the second plate body are plugged into the connecting plate, the shrinkage force generated when the box body of the refrigerator shrinks can first act on the connection position between the first plate body and the second plate body of the forming plate, that is, the connecting plate is first displaced or deformed, so that the shrinkage force of the front part of the box body can be reduced, thereby reducing the deformation amount of the front side of the box body, and then reducing the shrinkage deformation amount of the front part of the box body as much as possible, and ensuring the assembly accuracy of the internal structural parts of the box body.

[0073] At the same time, after the foaming layer is completed, it shrinks due to the decrease in temperature, forcing the back panel to be concave toward the inside of the refrigerator and deform vertically; by constructing the connecting plate, the first plate body and the second plate body to extend vertically, the direction of deformation of the back panel can be followed, so that the back panel can better adapt to the deformation and improve the overall strength and stability of the back panel.
