[0051] In some embodiments of the present application, a refrigerator is provided, comprising:

[0052] The box body 100 has a storage space 121 formed therein.

[0053] In some embodiments, the box body 100 includes a box shell 110, which is used to form an outer shell of the box body 100;

[0054] The inner liner 120 is arranged inside the box shell 110 , and a storage space 121 is defined inside the inner liner 120 .

[0055] The storage space 121 inside the inner container 120 can be used to realize refrigerated storage of food placed in the refrigerator.

[0056] The box frame 130 is arranged at the top of the box shell 110 and the inner liner 120, and is respectively connected and fixed to the inner liner 120 and the box shell 110.

[0057] A foaming cavity 140 is formed between the box frame 130 , the inner liner 120 and the box shell 110 . The foaming cavity 140 is filled with a foaming material, and the box body 100 is thermally insulated by the foaming material.

[0058] In some embodiments of the present application, a first folding edge extending downward is formed on the inner side of the box frame 130, and a first slot 135 is formed at the bottom of the first folding edge;

[0059] A second folded edge 136 extending downward is formed on the outer side of the box frame 130 .

[0060] When connected, the box frame 130 is plugged and fixed to the inner liner 120 through the first slot 135 on the first folded edge, and is wrapped around the outer surface of the box shell 110 through the second folded edge 136 to achieve connection and fixation with the box shell 110.

[0061] In some embodiments, an evaporation tube is wound around the outer side of the inner liner 120 to form an evaporator, which can directly transfer cold energy to the inner liner 120 to achieve the effect of refrigerating the food stored in the inner liner 120 .

[0062] In some embodiments, the box frame 130 includes a box frame main body, the top of which is a flat surface for docking with the door body 200 .

[0063] The door body 200 is connected to the box body 100 to open or close the storage space 121 .

[0064] In some embodiments, the door body 200 is rotatably connected to the box body 100 via a hinge, so as to open or close the storage space 121 by rotating relative to the box body 100 .

[0065] In some embodiments, in order to achieve sealing of the door body 200 and the box body 100 , a sealing strip 800 is correspondingly mounted on the door body 200 .

[0066] When the door body 200 is closed, the sealing strip 800 on the door body 200 is squeezed between the main body of the box frame and the door body 200 to achieve sealing of the door body 200 and the box frame 130 .

[0067] The sealing strip 800 is arranged along the circumference of the door body 200 so as to completely seal the storage space 121 when the door body 200 is closed.

[0068] The box frame 130 is formed with: a first connecting portion 131 for connecting with the external space of the refrigerator when the door body 200 is closed;

[0069] The first communicating portion 131 is a first communicating hole formed on the box frame 130 . One or more first communicating holes may be provided. When the door body 200 is closed, the first communicating holes may be correspondingly communicated with the external space.

[0070] The second connecting portion 132 is used to connect the storage space 121 when the door body 200 is closed.

[0071] The second connecting portion 132 is a second connecting hole opened on the box frame 130 . One or more second connecting holes may be provided. When the door body 200 is closed, the second connecting hole may be connected to the storage space 121 inside the box body 100 accordingly.

[0072] In some embodiments, when the door body 200 is closed, the sealing strip 800 is in contact with the top surface of the box frame 130 to separate the first connecting portion 131 on the outside of the sealing strip 800 and the second connecting portion 132 on the inside of the sealing strip 800 .

[0073] Through the separation of the sealing strip 800, the second connecting portion 132 on the inner side of the sealing strip 800 is connected to the internal storage space 121, while the first connecting portion 131 on the outer side of the sealing strip 800 is connected to the external space of the refrigerator.

[0074] In some embodiments, the air pressure balancing module includes:

[0075] The main balancing component 300 has an air pressure balancing channel formed therein, one end of the air pressure balancing channel being in communication with the first communicating portion 131 , and the other end of the air pressure balancing channel being in communication with the second communicating portion.

[0076] The air pressure balance channel is connected to the first connecting portion 131 at one end and to the second connecting portion 132 at the other end, so that the air pressure balance channel is connected to the storage space 121 and the external space of the refrigerator.

[0077] The moving component 400 is movably arranged in the air pressure balance channel, and is used to move relative to the air pressure balance channel to balance the pressure difference between the inside and outside of the refrigerator when there is a pressure difference between the inside and outside of the refrigerator.

[0078] In some embodiments, the moving component 400 is a ball or a roller, and its material is glass.

[0079] When the refrigerator is in normal use, the pressure in the storage space 121 inside the refrigerator and the space outside the refrigerator remain equal. At this time, the movable component 400 is sealed inside the air pressure balance channel to separate the space inside and outside the refrigerator to prevent cold air leakage inside the storage space 121.

[0080] When the refrigerator door is opened frequently and repeatedly, negative pressure is generated in the internal storage space 121, which makes it difficult to open the door due to the pressure difference between the inside and outside of the cabinet 100.

[0081] At this time, the pressure of the external space of the refrigerator is greater than the pressure of the internal storage space 121. Since the first connecting part 131 is connected to the external space of the refrigerator and one end of the air pressure balance channel, and the second connecting part 132 is connected to the storage space 121 and the other end of the air pressure balance channel, the air flow pressure in the external space will act on the movable part 400, pushing the movable part 400 to move in the air pressure balance channel to balance the pressure difference between the inside and outside of the refrigerator. At this time, the door body 200 can be opened to solve the problem of difficulty in opening the refrigerator door.

[0082] The air pressure balancing mechanism used to balance the pressure difference between the inside and outside of the refrigerator is assembled by setting an air pressure balancing module. The modular setting method realizes the integration of the air pressure balancing structure and simplifies the overall structure.

[0083] During assembly, it is only necessary to install the main balancing component 300 onto the box frame 130 and then connect the two ends of the air pressure balancing channel to the first connecting portion 131 and the second connecting portion 132 respectively. There is no need to set a long connecting pipeline, the connecting pipe structure is omitted, and the overall structure is simplified.

[0084] The air pressure balance module is assembled as a whole to the box frame. Compared with the multiple split assembly methods in the prior art in which some components need to be assembled to the front shell and some components need to be assembled to the rear shell, the assembly operation is simpler, more convenient and faster, thereby improving the assembly efficiency.

[0085] The air pressure balance module is assembled on the box frame 130 and is located in the foaming cavity 140. When the box body 100 foams, the air pressure balance module can be squeezed by the foaming material to achieve compression and fixation of the air pressure balance module, thereby ensuring the firmness of the assembly of the air pressure balance module.

[0086] In some embodiments, the air pressure balance module is arranged at the bottom of the box frame 130 so that it is built into the foaming cavity 140 and is not exposed to the outside, thereby ensuring the overall aesthetics of the entire refrigerator.

[0087] In some embodiments of the present application, a mounting portion 133 is formed on the box frame 130;

[0088] and a positioning portion formed on the assembly portion 133;

[0092] And a positioning matching portion formed on the connecting portion is used to cooperate with the positioning portion to position the main body balancing component 300.

[0093] During assembly, the main body balancing component 300 can be matched with the positioning portion on the upper part thereof and the positioning matching portion on the connecting portion, so that the main body balancing component can be quickly positioned to achieve rapid connection and assembly with the box frame 130 .

[0094] In some embodiments of the present application, the main balancing component 300 includes: a first balancing piece 340 , and a first channel 341 is formed in the first balancing piece 340 .

[0095] and a second balancing member 350 connected to the first balancing member 340 , wherein a second channel 351 is formed in the second balancing member 350 and is docked with the first channel 341 , and an air flow passage portion is formed on the second channel 351 ;

[0097] The moving component 400 is movably disposed in the second channel 351 to separate or connect the second channel 351 and the third channel 352 .

[0098] The main balancing member 300 is arranged in a structure in which the first balancing member 340 and the second balancing member 350 cooperate with each other, so that installation and assembly can be facilitated.

[0099] The air pressure balance channel is formed by the first channel 341 in the first balance member 340 and the second channel 351 and the third channel 352 in the second balance member 350 .

[0100] The moving component 400 moves in the second channel 351 to achieve blocking or connecting the air pressure balance channel.

[0104] In some embodiments of the present application, the first positioning protrusion is a first positioning column, and the second positioning protrusion is a second positioning column, which are extended from the assembly surface and are integrally presented with the assembly surface during molding.

[0105] The connecting portion includes a first connecting portion 321 formed on the first balancing member 340 , and a first positioning matching portion 322 for matching with the first positioning portion 1341 is formed on the first connecting portion 321 ;

[0106] In some embodiments, the connecting portion is a first connecting platform formed on the top of the first balancing member 340 , and a first connecting surface is formed on the first connecting platform, which is a plane for fitting with the assembly surface.

[0107] The first positioning and matching portions 322 are first positioning and matching holes formed on the first connecting platform. The number of the first positioning and matching holes is the same as the number of the first positioning protrusions, and the first positioning and matching holes are used for inserting and matching with the first positioning protrusions to position the main balancing component 300 .

[0112] In some embodiments of the present application, the refrigerator includes:

[0113] The first bonding member 510 has two sides respectively bonded to the first connecting portion 321 and the assembly portion 133 , and its shape is adapted to the first connecting portion 321 .

[0114] In some embodiments, the first adhesive member 510 is a first adhesive foam with double-sided adhesive, which has two adhesive surfaces. When connected, it is respectively bonded and connected to the first connecting portion 321 and the assembly portion 133 through the two adhesive surfaces.

[0115] The first bonding member 510 is configured to match the shape of the first connecting portion 321 , mainly for increasing the connecting area of ​​the first connecting portion 321 and ensuring the connecting strength.

[0116] The first adhesive foam can not only realize the connection between the first balancing member 340 and the box frame 130 , but also realize the sealing between the first balancing member 340 and the box frame 130 , thereby saving sealing materials and reducing costs.

[0117] In some embodiments, a first avoiding portion 511 for avoiding the first positioning portion 1341 and a first connecting channel 512 connecting the first channel 341 and the second communicating portion 132 are provided on the first connecting portion 321 .

[0118] The first avoiding portion 511 is a first avoiding gap, which is used to avoid the first positioning portion 1341 .

[0119] The first connecting channel 512 is connected between the first channel 341 and the second communicating portion 132 to achieve communication between the first channel 341 and the second communicating portion 132 .

[0120] The second bonding member 520 is bonded to the second connecting portion 323 and the assembly portion 133 , respectively, and its shape is adapted to the second connecting portion 323 .

[0121] In some embodiments, the second adhesive member 520 is a second adhesive foam with double-sided adhesive, which has two adhesive surfaces. When connected, it is respectively bonded and connected to the first connecting portion 321 and the assembly portion 133 through the two adhesive surfaces.

[0122] The second bonding member 520 not only realizes the connection between the second balancing member 350 and the box frame 130 , but also realizes the sealing between the second balancing member 350 and the box frame 130 .

[0123] In some embodiments, the second adhesive member 520 is provided with a second avoiding portion 521 avoiding the second positioning portion 1342 and a second connecting channel 522 connecting the third channel 352 and the first connecting portion 131 .

[0124] The second avoiding portion 521 is a second avoiding gap, which is used to avoid the second positioning portion 1342 .

[0125] The second connection channel 522 is connected between the third channel 352 and the first communication portion 131 to achieve communication between the third channel 352 and the first communication portion 131 .

[0126] In some embodiments of the present application, the second channel 351 includes: an inclined section, which is arranged to extend obliquely upward, and the inner diameter of the inclined section gradually decreases from a direction close to the storage space 121 to a direction away from the storage space 121.

[0127] The inclined section is arranged to be inclined upward and the inner diameter is arranged to be larger as it is closer to the storage space 121, which means that the inner diameter is larger as it is closer to the top of the inclined section, and the inner diameter is smaller as it is closer to the bottom of the inclined section.

[0128] When the pressure difference between the inside and outside of the refrigerator is equal, the movable component 400 will be located at a certain external position of the inclined section, blocking the second channel 351, and then blocking the air pressure balance channel;

[0129] When there is a pressure difference inside and outside the refrigerator, the movable component 400 will move upward along the inclined section. As the inner diameter of the inclined section continues to increase, a gap will be formed between it and the inclined section. At this time, the space inside and outside the refrigerator is connected, and the pressure difference inside and outside the refrigerator is balanced.

[0130] After the pressure difference between the inner and outer spaces is balanced, since the inclined section is arranged inclined, the movable component 400 can automatically slide down to the blocking position of the inclined section under the action of its own gravity.
