[0002] The temperature inside the refrigeration equipment is relatively low, especially for equipment used to freeze items such as refrigerators and freezers. The temperature inside the box is below zero degrees. The low temperature can easily cause the door of the refrigeration equipment to deform, resulting in poor sealing of the refrigeration equipment and reducing the refrigeration effect of the refrigeration equipment.

[0003] At present, in the related art, reinforcing iron is usually arranged on the frame of the door body of the refrigeration equipment, and the reinforcing iron supports the frame and reduces the deformation of the frame, thereby reducing the deformation of the door body such as warping and twisting.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the deformation of the door frame can be reduced by reinforcing parts, but when the door cover is installed on the box body, the cold inside the box body is transferred to the door body through the inner wall surface of the door body, and the inner wall surface of the door body will also deform. The deformation of the door frame is aggravated by the deformation of the inner wall surface of the door body.

[0042] 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.

[0043] The embodiment of the present disclosure provides a refrigeration device, which includes a door body and a box body for the refrigeration device, wherein the box body defines a storage space for placing food or items to be refrigerated or frozen. The door body cover is arranged on the box body to seal and insulate the storage space.

[0044] The present disclosure provides a door body for a refrigeration device, such as Figures 1 to 6 As shown, the door body for refrigeration equipment includes a door frame 100, a front panel 200, a door lining 300 and a reinforcing plate 400. The front panel 200 is arranged at the front side of the door frame 100, the door lining 300 is arranged at the rear side of the door frame 100, and the door lining 300, the front panel 200 and the door frame 100 jointly enclose a foaming space 110, and the foaming material can foam in the foaming space 110 to form a foaming layer.

[0045] One wall surface of the reinforcing plate 400 is connected to the side wall of the door lining 300 facing the foaming space 110 , and the other wall surface of the reinforcing plate 400 is used to connect to the foaming layer. The reinforcing plate 400 is used to support the door lining 300 .

[0046] In this embodiment, Figure 3 and Figure 5 As shown, the door lining 300, the front panel 200 and the door frame 100 together enclose a foaming space 110, and the foaming material foams in the foaming space 110 to form a foaming layer, so that the door body has a heat preservation effect. The front panel 200 is arranged on the front side of the door frame 100, and the front panel 200 is located on the side of the door body away from the box body. The door lining 300 is arranged on the rear side of the door frame 100, and the door lining 300 is located on the side of the door body facing the box body, and the coldness inside the box body can be transferred to the door body through the door lining 300.

[0047] One wall surface of the reinforcing plate 400 is connected to the side wall of the door lining 300 facing the foaming space 110, and the other wall surface of the reinforcing plate 400 is connected to the foaming layer. That is to say, after the foaming material is foamed, the reinforcing plate 400 is arranged between the foaming layer and the door lining 300. In this way, the reinforcing plate 400 can support the foaming layer and the door lining 300. When the foaming layer or the door lining 300 has a tendency to deform, the reinforcing plate 400 can use its own bending resistance to block the deformation of the foaming layer or the door lining 300, so as to reduce the deformation of the foaming layer and the door lining 300 at low temperatures, thereby reducing the deformation of the frame and the door body, improving the sealing effect of the door body on the box body and the cooling effect of the box body, and improving the user experience.

[0048] In some optional embodiments, the reinforcing plate 400 is made of glass fiber composite material.

[0049] Glass fiber composite materials refer to composite materials with glass fiber as reinforcement and other composite materials as matrix. Glass fiber composite materials have the advantages of high strength, light weight, aging resistance, good flame retardancy, sound insulation and heat insulation.

[0050] In this embodiment, the reinforcing plate 400 is made of glass fiber composite material, which can reduce the deformation of the reinforcing plate 400 at low temperatures compared to the metal material used for the reinforcing member in the prior art. In particular, when the temperature in the box reaches below -38 degrees, the reinforcing member made of metal material in the prior art will deform. At this time, the reinforcing member not only cannot support the door lining 300 and the foaming layer, but also transmits its own deformation to the door lining 300 or the foaming layer, further aggravating the deformation of the door body.

[0051] In this embodiment, the reinforcing plate 400 is made of glass fiber composite material, which can reduce the deformation of the reinforcing plate 400, improve the support for the door lining 300 and the foaming layer, and reduce the risk of deformation of the door body at low temperatures. In addition, the glass fiber composite material also has heat insulation properties, which can reduce the amount of cold transferred from the door lining 300 to the foaming layer, thereby reducing the deformation of the foaming layer and the heat loss of the door body.

[0052] Optionally, an adhesive layer is provided between the reinforcing plate 400 and the door lining 300 .

[0053] In this embodiment, after the door lining 300, the front panel 200 and the door frame 100 enclose the foaming space 110, the foaming material foams in the foaming space 110. Before the foaming material foams, the reinforcing plate 400 can be installed on the door lining 300 through the adhesive layer to position the reinforcing plate 400.

[0054] After the foaming material is foamed, the reinforcing plate 400 can not only be installed on the door liner 300 through the adhesive layer, but the reinforcing plate 400 can also be foamed and laminated on the door liner 300 to improve the stability and reliability of the reinforcement member setting.

[0055] Optionally, the adhesive layer includes double-sided tape, glue, etc.

[0056] In some optional embodiments, such as Figures 2 to 5 As shown, the door lining 300 includes a first plate 310 and a second plate 320 connected to each other, the first plate 310 is connected to the door frame 100, and the inner wall of the first plate 310 is connected to the outer wall of the second plate 320. The second plate 320 is used to protrude toward the box body, and a first folded angle is provided at the connection between the first plate 310 and the second plate 320, and the opening of the first folded angle faces the box body.

[0057] The reinforcing plate 400 is disposed at the connection between the first plate body 310 and the second plate body 320 .

[0058] In this embodiment, the first plate 310 is connected to the door frame 100, the inner wall of the first plate 310 is connected to the outer wall of the second plate 320, the first plate 310 is surrounded by the outer side of the second plate 320, and the second plate 320 is arranged corresponding to the internal space of the box.

[0059] The second plate body 320 protrudes toward the box body, the opening of the first folded corner faces the box body, and a portion of the second plate body 320 is tilted.

[0060] In this way, the thickness of the foaming space 110 corresponding to the second plate body 320 is greater than the thickness of the foaming space 110 corresponding to the first plate body 310 .

[0061] That is, the thickness of the foam layer corresponding to the second plate 320 is greater than the thickness of the foam layer corresponding to the first plate 310. This can improve the thermal insulation effect of the door body, thereby improving the refrigeration effect of the refrigeration equipment and improving the user experience.

[0062] The reinforcing plate 400 is arranged at the connection between the first plate body 310 and the second plate body 320, that is, the reinforcing plate 400 is arranged at the first corner between the first plate body 310 and the second plate body 320. This can increase the deformation resistance of the first plate body 310 and the second plate body 320 at the first corner, reduce the deformation risk of the door lining 300 due to bending, thereby reducing the deformation of the frame and the door body, improving the sealing effect of the door body on the box body and the cooling effect of the box body, and improving the user experience.

[0063] Furthermore, if Figure 4 , Figure 5 and Figure 6 As shown, the reinforcing plate 400 includes a first sub-reinforcing plate 410 and a second sub-reinforcing plate 420. The first sub-reinforcing plate 410 is arranged on the first plate body 310, and the second sub-reinforcing plate 420 is arranged on the second plate body 320. One end of the first sub-reinforcing plate 410 is connected to one end of the second sub-reinforcing plate 420, and there is a second fold angle between one end of the first sub-reinforcing plate 410 and one end of the second sub-reinforcing plate 420.

[0064] In this optional embodiment, the first sub-reinforcement plate 410 is provided on the first plate body 310, and the first sub-reinforcement plate 410 can support the first plate body 310. The second sub-reinforcement plate 420 is provided on the second plate body 320, and the second sub-reinforcement plate 420 can support the second plate body 320. In this way, the first plate body 310, the second plate body 320, and the connection between the first plate body 310 and the second plate body 320 are supported, thereby improving the anti-deformation ability of the door lining 300.

[0065] Optionally, the angle of the first fold angle is the same as the angle of the second fold angle.

[0066] Optionally, an extension width of the first sub-reinforcement board 410 is greater than an extension width of the second sub-reinforcement board 420 .

[0067] In this embodiment, the portion of the second plate body 320 connected to the first plate body 310 is tilted, that is, the portion of the second plate body 320 provided with the second sub-reinforcement plate 420 is tilted. The extension width of the first sub-reinforcement plate 410 is greater than the extension width of the second sub-reinforcement plate 420, so that the reinforcement plate 400 can be adapted to the door lining 300.

[0068] Exemplarily, the first inner sidewall of the first plate body 310 is connected to the first outer sidewall of the second plate body 320 , the second inner sidewall of the first plate body 310 is connected to the second outer sidewall of the second plate body 320 , and the first inner sidewall and the second inner sidewall are arranged opposite to each other.

[0069] A reinforcing plate 400 is respectively provided at a connection point between the first inner side wall and the first outer side wall and at a connection point between the second inner side wall and the second outer side wall.

[0070] Alternatively, if Figure 3 As shown, there are multiple reinforcing plates 400, including a first reinforcing plate 401 and a second reinforcing plate 402. The first reinforcing plate 401 is arranged at the connection between the first inner wall and the first outer wall, and the second reinforcing plate 402 is arranged at the connection between the second inner wall and the second outer wall.

[0071] Reinforcing plates 400 are respectively provided on the opposite sides of the second plate body 320, which can improve the deformation resistance of the door lining 300 and reduce the deformation of the door body, thereby improving the sealing effect of the door body on the box body and the cooling effect of the refrigeration equipment.

[0072] Exemplarily, an extension distance of the door body along a first direction is set as the length of the door body, an extension distance of the door body along a second direction is set as the width of the door body, and the first direction and the second direction are perpendicular to each other.

[0073] The length of the door body is greater than the width of the door body. The first inner side wall, the second inner side wall, the second outer side wall and the first outer side wall all extend along the first direction. The length direction of the first reinforcing plate 401 and the second reinforcing plate 402 is the same as the first direction. In this way, the first reinforcing plate 401 and the second reinforcing plate 402 extend along the longer direction of the door lining 300. The longer the length of the door lining 300, the worse the deformation resistance of the door lining 300. In this embodiment, the deformation resistance of the door lining 300 in the length direction can be improved by the first reinforcing plate 401 and the second reinforcing plate 402, so as to reduce the deformation of the door lining 300 in a low temperature environment, thereby reducing the deformation of the door body and improving the sealing effect of the door body on the box body.

[0074] Optionally, the third inner wall of the first plate body 310 is connected to the third outer wall of the second plate body 320, the third inner wall and the third outer wall extend along the second direction, and the third reinforcing plate is provided at the connection between the third inner wall and the third outer wall. The length direction of the third reinforcing plate is the same as the second direction.

[0075] Optionally, the fourth inner wall of the first plate body 310 is connected to the fourth outer wall of the second plate body 320, the fourth inner wall and the fourth outer wall extend along the second direction, the fourth inner wall is arranged opposite to the third inner wall, and the fourth outer wall is arranged opposite to the third inner wall. The fourth reinforcing plate is arranged at the connection between the fourth inner wall and the fourth outer wall, and the length direction of the fourth reinforcing plate is the same as the second direction.

[0076] In some optional embodiments, such as Figure 3 As shown, along the length direction of the reinforcing plate 400 , the length of the reinforcing plate 400 is greater than or equal to 0.75 times the connection extension length.

[0077] The connection extension length is the extension length of the connection between the first plate body 310 and the second plate body 320 along the length direction of the reinforcing plate 400 .

[0078] According to this optional embodiment, along the length direction of the reinforcing plate 400, the length of the reinforcing plate 400 is greater than or equal to 0.75 times the connection extension length. In this way, the connection length and area of ​​the first plate body 310 and the second plate body 320 and the reinforcing plate 400 are increased, and the supporting effect of the reinforcing plate 400 and the door lining 300 is improved.

[0079] Exemplarily, the length of the reinforcing plate 400 may be 0.75, 0.8, 0.85, 0.9 or 0.95 times the connection extension length, or the length of the reinforcing plate 400 may be 0.77, 0.82, 0.87, 0.92 or 0.97 times the connection extension length.

[0080] In this embodiment, the specific extension length of the reinforcing plate 400 can be set by those skilled in the art according to the specific length of the door lining 300. As long as the length of the reinforcing plate 400 is greater than or equal to 0.75 times the connection extension length, the specific length of the reinforcing plate 400 is not specifically limited herein.

[0081] Furthermore, the thickness of the reinforcing plate 400 is greater than or equal to 2 mm.

[0082] In this embodiment, the thickness of the reinforcing plate 400 is greater than or equal to 2 mm to improve the deformation resistance of the reinforcing plate 400, thereby improving the supporting effect of the reinforcing plate 400 on the door lining 300 or the foaming layer, reducing the deformation of the door body at low temperatures, and improving the sealing effect of the door body on the box body and the cooling effect of the refrigeration equipment.

[0083] Illustratively, the thickness of the reinforcing plate 400 may be 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, 3.3 mm, 3.5 mm, 3.8 mm, or 4 mm.

[0084] Preferably, the thickness of the reinforcing plate 400 is 2.5 mm.

[0085] In this embodiment, the specific value of the thickness of the reinforcing plate 400 can be set according to the experience of those skilled in the art, or can be obtained through a limited number of experiments, and is not specifically limited here.
