DETAILED DESCRIPTION

[0027] In order to provide a further understanding of the purpose, structure, features, and functions of the present application, the following detailed description is given in conjunction with the embodiments.

[0028] According to the embodiments of this application, for the sake of clarity, Figure 2 An xyz coordinate system is given, wherein arrows schematically show the width direction x, depth direction y, and height direction z of the refrigeration appliance which are perpendicular to each other in a normal use state.

[0029] It should be pointed out that Figure 1 The multi-door refrigerator is used as an example for exemplary display. In actual application, the structure of this embodiment can also be applied to other types of refrigeration appliances, such as side-by-side refrigerators, single-door refrigerators, refrigerators, freezers, etc. Figures 1 to 6 The various embodiments of the individual components described may be combined with one another in any given manner to achieve the advantages of the present application.

[0030] like Figures 1 to 6As shown, the refrigeration appliance 100 includes a box body 1, and the box body 1 includes a storage chamber 12 with a front opening. The storage chamber 12 is used to refrigerate or freeze items. The box body 1 includes an outer shell 13 defining the outer surface of the box body and an inner shell 14 located inside the outer shell 13, and a heat insulation layer 15 formed by foaming a foam material is provided between the outer shell 13 and the inner shell 14. The heat insulation layer is used to prevent the storage chamber from exchanging heat with the external environment, thereby affecting the refrigeration effect of the refrigeration appliance.

[0031] The refrigeration appliance 100 includes a front beam 8 extending along the width direction of the storage chamber 12. The storage chamber 12 is divided into an upper storage space 9 and a lower storage space 10 relative to the front beam 8. The front surface of the front beam 8 and the front end surface of the box body 1 are substantially in the same plane.

[0032] The refrigeration appliance 100 includes a door 2 for opening and closing a storage chamber 12. According to one embodiment of the present application, the door 2 includes a first door for opening and closing an upper storage space 9 and a second door for opening or closing a lower storage space 10.

[0033] The door 2 is rotatably mounted on the front side of the box body 1 through a hinge assembly 3. In the embodiment of the present application, the hinge assembly 3 is arranged at the top, middle and bottom of the box body 1, so as to support the first door and the second door arranged up and down along the height direction of the refrigeration appliance. In other embodiments, such as a side-by-side refrigerator, including two doors arranged on the left and right, hinge assemblies are arranged at the top and bottom of the door.

[0034] like Figures 2 to 6 As shown, taking the hinge assembly arranged in the middle as an example, the hinge assembly 3 includes a base 31 connected to the front beam 8. The base 31 may be provided with a plurality of through holes 311 so as to allow fasteners (not shown) to pass through the base 31 to fix the hinge assembly 3 on the front beam 8. The hinge assembly 3 also includes a hinge shaft 316 located on the base 31, specifically, the base 31 includes a first base 312 close to the front beam 8 and a second base 313 away from the front beam 8, wherein the hinge shaft 316 is located on the second base 313. The hinge shaft 316 defines the rotation axis of the door, so that the door rotates along the rotation axis of the hinge shaft to open or close the front opening of the storage chamber.

[0035] like Figure 2 As shown, the housing 13 includes a side plate 132 defining a side surface of the box body 1 and a top plate 133 defining a top surface of the box body 1 , and the top plate 133 is connected to the side plate 132 .

[0036] like Figure 4As shown, the side plate 132 includes a main body 1321 facing the side of the box body and a front side 1322 located at the front side of the box body. The main body 1321 defines the side surface of the housing 13. The front side 1322 includes a first wall 1323, a second wall 1324 connected to the first wall 1323, and a third wall 1325 connected to the second wall 1324. Specifically, a cavity 131 is formed between the third wall 1325 and the first wall 1323.

[0037] The cavity 131 is close to the front side of the box body 1 , and the end of the inner shell 14 is inserted into the cavity 131 , thereby achieving installation between the outer shell and the inner shell.

[0038] In order to improve the load-bearing capacity of the front beam, the front beam 8 includes a reinforcing plate 81 . The reinforcing plate 81 includes an extending portion 811 extending toward the side plate 132 . The extending portion 811 is configured to extend into the receiving cavity 131 .

[0039] The hinge assembly at the bottom of the door body is used to bear the weight of the door. When the door body is too heavy, the hinge may be deformed, causing the door body to sink. In order to improve the assembly strength of the hinge assembly, a reinforcement member 4 is provided on the shell 13, and the reinforcement member 4 is fixed on the shell 13, so as to improve the support and limit effect of the hinge assembly and prevent the hinge assembly from displacement.

[0040] like Figure 4 As shown, the reinforcement 4 is located at the rear wall of the cavity 131. Specifically, the reinforcement 4 is located at the side of the third wall 1325 facing away from the cavity 131. The end of the inner shell 14 is inserted into the cavity 131, so that the reinforcement 4 is located at the rear side of the end of the inner shell 14.

[0041] According to one embodiment of the present application, Figure 6 As shown, the reinforcement member 4 includes a receiving portion 6 and mounting portions 41 located on both sides of the receiving portion 6. Specifically, mounting holes 410 are provided on the mounting portion 41.

[0042] The third wall 1325 is provided with an opening 1327 at the installation position relative to the reinforcement member 4. The opening 1327 can be a closed hole or a U-shaped opening. In the embodiment of the present application, the opening 1327 is a U-shaped opening.

[0043] Specifically, the reinforcement member 4 covers the area where the opening 1327 is located, and the receiving portion 6 is arranged opposite to the opening 1327. First holes 1328 adapted to the mounting holes 410 are arranged on both sides of the opening 1327 at positions opposite to the mounting holes 410 of the reinforcement member 4, so as to allow fasteners (not used) to pass through the mounting holes and the first holes to fix the reinforcement member to the third wall.

[0044] In order to realize the installation of the hinge assembly and the reinforcement, a fixing portion 5 is provided on the base 31 of the hinge assembly 3. Specifically, the fixing portion 5 is configured as a protrusion extending in a direction away from the base 31. A second hole 1329 adapted to the fixing portion 5 is provided on the first wall 1323 and the second wall 1324.

[0045] In one embodiment of the present application, Figures 5 and 6 As shown, the receiving portion 6 is constructed as a groove. Specifically, the end of the fixing portion 5 is located in the receiving portion 6. The receiving portion 6 has a bottom 61 in the direction in which the fixing portion 5 enters the receiving portion 6. The bottom 61 is arranged opposite to the opening 1327. The fixing portion 5 does not penetrate the receiving portion 6, that is, the end of the fixing portion 5 does not exceed the depth area defined by the receiving portion 6. As a result, the receiving portion wraps the end of the fixing portion, which is conducive to enhancing the support and limiting effect on the hinge assembly and preventing the hinge assembly from being displaced.

[0046] In other embodiments, the base 31 is provided with a receiving portion 6. Specifically, the receiving portion 6 is configured as a groove. The reinforcement member 4 includes a fixing portion 5. Specifically, the fixing portion 5 is configured as a protrusion. Thus, the fixing portion is suitable for being inserted into the receiving portion, thereby playing a supporting and limiting role for the hinge assembly.

[0047] In order to accommodate the end of the fixing part entering the receiving part, the extension distance of the receiving part 6 in the front-to-back direction is not less than 3 mm. In this way, when the fixing part enters the bottom of the receiving part, the fixing part and the receiving part have an overlapping part in the height direction of the refrigerating appliance. Preferably, the fixing part and the receiving part have an overlapping part in the height direction of the refrigerating appliance of not less than 3 mm. Therefore, when the door is installed on the hinge assembly, the door applies gravity to the hinge assembly, and the reinforcement applies a force on the hinge assembly in the opposite direction of the gravity of the door, thereby achieving support and limitation of the hinge assembly.

[0048] In order to improve the assembly strength of the hinge assembly and the box body, the wall thickness of the reinforcement member 4 is greater than the wall thickness of the outer shell 13. Specifically, the wall thickness of the reinforcement member 4 is 2 to 6 times the wall thickness of the outer shell 13. In one embodiment of the present application, the single-layer wall thickness of the outer shell 13 is 0.45 mm, and the wall thickness of the reinforcement member 4 is 2.5 mm.

[0049] In the embodiment of the present application, the reinforcement member 4 is integrally formed.

[0050] like Figure 5 As shown, when the heat insulation layer 15 is foamed between the outer shell 13 and the inner shell 14, the heat insulation layer 15 enters the cavity 131, thereby the fixing portion 5 passes through the side panel 132, the front beam 8, and the heat insulation layer 15 to reach the bearing portion 6 of the reinforcement 4, thereby the side panel, the front beam, the heat insulation layer and the reinforcement jointly support and limit the hinge assembly, thereby further improving the assembly strength of the hinge assembly.

[0051] Combination Figures 1 to 6 The various embodiments of the individual components described may be combined with one another in any given manner to achieve the advantages of the present application.

[0052] The present application has been described by the above-mentioned relevant embodiments, but the above-mentioned embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, changes and modifications made without departing from the spirit and scope of the present application are all within the scope of patent protection of the present application.
