To achieve the above purpose, the utility model provides a refrigerator, comprising:
[0007] A housing, wherein the housing is provided with at least one opening;
[0008] A box body, the box body is arranged in the shell, the box body has an opening and corresponds to the opening of the shell;
[0009] An installation box formed between the housing and the box body;
[0010] A compressor, the compressor being arranged between the shell and the box body;
[0011] an evaporator, the evaporator being arranged inside the installation box and connected to the compressor;

The gap between the door liner and the box body is limited to between 2 and 5 mm to prevent the cold air inside the box from leaking excessively through the gap between the door liner and the box body, thereby improving the refrigeration efficiency of the freezer and reducing energy consumption.
[0017] In addition, the present application also provides a refrigerator, which includes:
[0018] A housing, wherein the housing is provided with at least one opening;
[0019] A box body, the box body is arranged in the shell, the box body has an opening and corresponds to the opening of the shell;
[0020] An installation box formed between the housing and the box body;
[0021] A compressor, the compressor being arranged between the shell and the box body;
[0022] an evaporator, the evaporator being arranged inside the installation box and connected to the compressor;
[0023] A return air inlet, the return air inlet is opened in the installation box and communicates with the interior of the box;

[0026] When the door body closes the opening of the box body, the distance between any two nearest points between the door liner and the box body is between 2 and 5 mm.
[0027] In the technical solution, the door body is used to close the opening of the box body. When the door body closes the opening of the box body, part of the door liner is inserted into the opening of the box body to form a tightly closed structure. The gap between the door liner and the box body is limited to between 2 and 5 mm to prevent the cold air inside the box from leaking excessively through the gap between the door liner and the box body, thereby improving the refrigeration efficiency of the freezer and reducing energy consumption.

[0034] In some embodiments of the present application, the air outlet direction of the air outlet is inclined toward the bottom of the box.
[0035] In the technical solution, it is conducive to forming a cold air flow from top to bottom, ensuring that the items at the bottom of the box can also be fully cooled. It also avoids the possibility that the cold air will blow directly to the gap between the door liner and the box, and avoids the cold air from leaking directly through the gap between the door liner and the box.
[0036] In some embodiments of the present application, the door liner is provided with a rib plate protruding toward the box body; the rib plate is provided along the edge of the door liner;
[0037] The air outlet is located below the rib plate.
[0038] In the technical solution, the sealing between the door body and the box body can be increased to reduce the leakage of cold air. The rib plate is arranged along the edge of the door liner, which helps to form a more uniform sealing surface and improve the sealing effect. The air outlet is located below the rib plate, which can ensure that the cold air will not blow directly into the gap between the door liner and the box body, further reducing the risk of cold air leakage.
[0039] In some embodiments of the present application, the distance between the air outlet and the rib plate is not less than 7 mm.
[0040] In the technical solution, it can be ensured that the cold air will not be directly blocked by the rib plate when it flows out, thereby maintaining the fluency and cooling effect of the cold air. It also prevents the cold air from blowing directly into the gap between the door liner and the box body, further reducing the risk of cold air leakage.
[0041] In some embodiments of the present application, a box frame is provided at the opening of the box body and at the opening corresponding to the outer shell.
[0042] In the technical solution, the overall structural strength of the refrigerator can be enhanced and the sealing performance can be improved. The design of the box frame also helps to guide the door body to be accurately inserted into the opening of the box body, thereby improving the installation accuracy and stability of the door body.
[0043] In some embodiments of the present application, a sealing ring is provided between the box frame and the door panel.
[0044] In the technical solution, the sealing performance of the refrigerator can be further improved to prevent cold air leakage. In addition, the sealing ring can also reduce the friction and noise between the door body and the box frame, improving the user experience of the refrigerator.
[0045] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0064] Please refer to all the drawings, in an illustrative embodiment of the refrigerator of the utility model:
[0065] The refrigerator may include a housing 100 , and the housing 100 is provided with at least one opening.
[0066] In some embodiments, the refrigerator may include a box body 200 disposed in the housing 100 .
[0067] In some embodiments, the case 200 has an opening corresponding to the opening of the housing 100 .
[0068] In some embodiments, the refrigerator may include a mounting box 300 formed between the outer shell 100 and the cabinet 200 .
[0069] In some embodiments, the refrigerator may include a compressor 400 disposed between the housing 100 and the cabinet 200 .
[0070] In some embodiments, the refrigerator may include an evaporator 500 , which is disposed inside the installation box 300 , and the evaporator 500 is connected to the compressor 400 .
[0071] In some embodiments, the refrigerator may include a return air vent 600 , which is opened in the installation box 300 and communicates with the interior of the box body 200 .
[0072] In some embodiments, the refrigerator may include a door body 700 , and the door body 700 is disposed on the outer shell 100 .
[0073] The door body 700 is used to close the opening of the box body 200 .
[0074] In some embodiments, the door body 700 includes a door panel 701 .
[0075] In some embodiments, the door body 700 includes a door liner 702 , and the door liner 702 is at least partially used to be inserted into the opening of the box body 200 .
[0076] In some embodiments, when the door body 700 closes the opening of the box body 200, the gap between the door liner 702 and the box body 200 is not less than 2 mm.
[0077] When the gap between the door liner 702 and the box body 200 is close to 2 mm, the sealing performance between the door liner 702 and the box body 200 is best, and the cold air in the box body 200 is discharged to the outside of the box body 200 to a minimum, and the dimensional tolerance can meet the requirements of the door body 700 closing the box body 200.
[0078] If the gap between the door liner 702 and the box body 200 is less than 2 mm, it may cause dimensional tolerance problems, and interference may occur when the door body 700 closes the box body 200, resulting in failure to seal.
[0079] In some embodiments, when the door body 700 closes the opening of the box body 200, the gap between the door liner 702 and the box body 200 is no greater than 5 mm.
[0080] When the gap between the door liner 702 and the box body 200 is close to 5 mm, the sealing effect can be ensured. If the gap between the door liner 702 and the box body 200 is greater than 5 mm, the sealing between the door body 700 and the box body 200 cannot be achieved.
[0081] Through the above solution, the door body 700 is used to close the opening of the box body 200. When the door body 700 closes the opening of the box body 200, part of the door liner 702 is inserted into the opening of the box body 200 to form a tightly closed structure. The gap between the door liner 702 and the box body 200 is limited to between 2 and 5 mm, which prevents the cold air inside the box body 200 from leaking excessively through the gap between the door liner 702 and the box body 200, thereby improving the refrigeration efficiency of the refrigerator and reducing energy consumption.
[0082] Furthermore, because the sealing of the box body 200 is ensured, air leakage is avoided, and the formation of air leakage may cause condensation water to condense on the door body 700 and flow into the box body 200 when the box body 200 is opened. Therefore, through this design, the situation of condensation water flowing into the box body 200 is also reduced.
[0083] Please refer to all the drawings. In addition, the present application also provides a refrigerator. In some embodiments:
[0084] The refrigerator may include a housing 100 , and the housing 100 is provided with at least one opening.
[0085] In some embodiments, the refrigerator may include a box body 200 disposed in the housing 100 .
[0086] In some embodiments, the case 200 has an opening corresponding to the opening of the housing 100 .
[0087] In some embodiments, the refrigerator may include a mounting box 300 formed between the outer shell 100 and the cabinet 200 .

[0089] In some embodiments, the refrigerator may include an evaporator 500 , which is disposed inside the installation box 300 , and the evaporator 500 is connected to the compressor 400 .
[0090] In some embodiments, the refrigerator may include a return air vent 600 , which is opened in the installation box 300 and communicates with the interior of the box body 200 .
[0091] In some embodiments, the refrigerator may include a door body 700 , and the door body 700 is disposed on the outer shell 100 .
[0092] The door body 700 is used to close the opening of the box body 200 .
[0093] In some embodiments, the door body 700 includes a door panel 701 .
[0094] In some embodiments, the door body 700 includes a door liner 702 , and the door liner 702 is at least partially used to be inserted into the opening of the box body 200 .
[0095] In some embodiments, when the door body 700 closes the opening of the box body 200, the distance between any two nearest points between the door liner 702 and the box body 200 is not less than 2 mm.
[0096] When the gap between the door liner 702 and the box body 200 is close to 2 mm, the sealing performance between the door liner 702 and the box body 200 is best, and the cold air in the box body 200 is discharged to the outside of the box body 200 to a minimum, and the dimensional tolerance can meet the requirements of the door body 700 closing the box body 200.
[0097] If the gap between the door liner 702 and the box body 200 is less than 2 mm, it may cause dimensional tolerance problems, and interference may occur when the door body 700 closes the box body 200, resulting in failure to seal.
[0098] In some embodiments, when the door body 700 closes the opening of the box body 200, the distance between any two nearest points between the door liner 702 and the box body 200 is no greater than 5 mm.
[0099] When the gap between the door liner 702 and the box body 200 is close to 5 mm, the sealing effect can be ensured. If the gap between the door liner 702 and the box body 200 is greater than 5 mm, the sealing between the door body 700 and the box body 200 cannot be achieved.
[0100] Through the above solution, the door body 700 is used to close the opening of the box body 200. When the door body 700 closes the opening of the box body 200, part of the door liner 702 is inserted into the opening of the box body 200 to form a tightly closed structure. The gap between the door liner 702 and the box body 200 is limited to between 2 and 5 mm, which prevents the cold air inside the box body 200 from leaking excessively through the gap between the door liner 702 and the box body 200, thereby improving the refrigeration efficiency of the refrigerator and reducing energy consumption.
[0101] Furthermore, because the sealing of the box body 200 is ensured, air leakage is avoided, and the formation of air leakage may cause condensation water to condense on the door body 700 and flow into the box body 200 when the box body 200 is opened. Therefore, through this design, the situation of condensation water flowing into the box body 200 is also reduced.
[0102] In some embodiments, a first step 800 is provided on one side of the box 200 close to the door 700, and a second step 900 corresponding to the first step 800 is provided on the inner liner. The sealing between the door 700 and the box 200 is further enhanced. When the door 700 is closed, the cold air inside the box 200 needs to pass through the gap between the first step 800 and the second step 900 and then pass through the corner before flowing out of the box 200, thereby blocking the path for the cold air to flow out. The risk of cold air leakage caused by poor sealing is reduced.

[0108] In some embodiments, the first table surface 801 is parallel to the inner bottom wall of the box body 200 .
[0109] In some embodiments, the second step 900 includes a second table surface 901 .
[0110] In some embodiments, when the door 700 closes the opening of the box 200, the first step 800 is parallel to the second step 900. Even when the door 700 is deformed, when the door 700 closes the box 200, the possibility of contact between the first step 800 and the second step 900 is reduced as much as possible.
[0111] In some embodiments, when the door body 700 closes the opening of the box body 200 , the first step 800 is parallel to the second step 900 , that is, the first table surface 801 is parallel to the second table surface 901 .

[0113] In some embodiments, the first side wall 802 is inclined in a direction away from the interior of the box body 200 .
[0114] In some embodiments, the first side wall 802 extends away from the bottom wall of the box body 200 .
[0115] In some embodiments, the first side wall 802 extends in a direction away from the bottom wall of the box body 200 and is inclined in a direction away from the interior of the box body 200 .
[0116] In some embodiments, the second step 900 further includes a second side wall 902. The second side wall 902 is connected to a side of the second side wall 902 away from the interior of the box body 200.
[0117] In some embodiments, the second side wall 902 is inclined in a direction away from the interior of the box body 200 .
[0118] In some embodiments, the second side wall 902 extends away from the bottom wall of the box body 200 .
[0119] In some embodiments, the second side wall 902 extends in a direction away from the bottom wall of the box body 200 and is inclined in a direction away from the interior of the box body 200 .

[0124] In some embodiments, an air outlet is provided on the vertical side wall of the box 200. Cold air can be more effectively introduced into the box 200 to improve the refrigeration efficiency. The provision of the air outlet also helps to form a circulating wind flow, promote the flow of internal air, and maintain a uniform temperature distribution.
[0125] In some embodiments, the air outlet direction of the air outlet is inclined toward the bottom of the box 200. This is conducive to forming a flow of cold air from top to bottom, ensuring that the items at the bottom of the box 200 can also be fully cooled. It also avoids the possibility that the cold air will blow directly toward the gap between the door liner 702 and the box 200, and avoids the cold air from leaking directly through the gap between the door liner 702 and the box 200.
[0126] In some embodiments, a rib plate 703 protruding toward the box body 200 is provided on the door liner 702 .
[0127] In some embodiments, the rib plate 703 is formed by bending the door liner 702 toward the box body 200 .

[0129] In some embodiments, the overall shape of the door liner 702 is rectangular, and the rib plate 703 is rectangular.
[0130] In some embodiments, the air outlet is located below the rib plate 703 .
[0131] The sealing between the door body 700 and the box body 200 can be increased to reduce cold air leakage. The rib plate 703 is arranged along the edge of the door liner 702, which helps to form a more uniform sealing surface and improve the sealing effect. The air outlet is located below the rib plate 703, which can ensure that the cold air will not blow directly to the gap between the door liner 702 and the box body 200, further reducing the risk of cold air leakage.
[0132] In some embodiments, the distance between the air outlet and the rib plate 703 is not less than 7 mm. This ensures that the cold air will not be directly blocked by the rib plate 703 when it flows out, thereby maintaining the fluency and cooling effect of the cold air. It also prevents the cold air from blowing directly into the gap between the door liner 702 and the box body 200, further reducing the risk of cold air leakage.
[0133] In some embodiments, a box frame is provided at the opening of the box body 200 and the opening corresponding to the outer shell 100. This can enhance the overall structural strength of the refrigerator and improve the sealing performance. The design of the box frame also helps guide the door body 700 to be accurately plugged into the opening of the box body 200, thereby improving the installation accuracy and stability of the door body 700.
[0134] In some embodiments, a sealing ring is provided between the box frame and the door panel 701. This can further improve the sealing performance of the refrigerator and prevent cold air leakage. In addition, the sealing ring can also reduce the friction and noise between the door body 700 and the box frame, thereby improving the user experience of the refrigerator.
