[0002] The refrigerator comprises a box body and a door body. A storage compartment is formed in the box body. A shelf device is arranged in the storage compartment, and the shelf device is used for placing articles.

[0003] Shelves are generally integrated or foldable. When there are no items on the shelf, the integrated shelf still takes up a large space. When it is necessary to make room, the shelf needs to be removed as a whole, which is inconvenient to install and disassemble. Therefore, foldable shelves are becoming more and more popular.

[0004] At present, the structure of the existing folding shelves is relatively complicated. The shelf device is easy to slide after being folded, and it is difficult to fix the folded shelf in the refrigerator. After the shelf device is folded, it is usually necessary to set a fixing device to keep the shelf device in a folded state. However, when the shelf device is changed from a flat state to a folded state, the shelf device and the fixing device need to be fixed, and when the shelf device is changed from a folded state to a flat state, the shelf device and the fixing device need to be unlocked. Therefore, it is necessary to constantly fix and unlock, which increases the operation steps, makes the user operation complicated, and also requires additional setting of fixing parts, which increases the raw material cost and assembly cost.

[0069] Among the width direction, front-back direction and height direction of the box body, two of them are perpendicular.

[0070] In some embodiments of the present application, reference Figure 1-Figure 2 The side of the box body 1 may be provided with a box body opening 11. The box body opening 11 may be located at the front side of the box body.

[0071] A storage compartment 12 may be defined in the box body 1. The storage compartment 12 may be used to store items.

[0072] The storage compartment 12 may be in communication with the box opening 11 .

[0073] The refrigerator 100 may include a door body 2. The door body 2 may be connected to the cabinet 1. The door body 2 may be connected at a cabinet opening 11 of the cabinet to open or close the cabinet opening 11. The door body 2 may be connected to the front side of the cabinet.

[0074] In some embodiments of the present application, the refrigerator 100 may include a hinge, and the refrigerator door may be rotatably connected to the cabinet through the hinge.

[0075] The hinge can be connected to one side end of the door body. The other side end of the door body can be close to or away from the box body to close or open the box body opening.

[0076] In some embodiments of the present application, the door body 2 can be connected to the box body in a pull-out manner. The box body opening can be closed or opened by pulling the door body.

[0083] In some embodiments of the present application, the refrigerator 100 may include an evaporator.

[0084] An evaporator cavity may be formed in the housing 1. The evaporator cavity may be disposed between the housing shell and the housing inner liner. The evaporator may be disposed in the evaporator cavity.

[0085] In some embodiments of the present application, the refrigerator 100 may include a refrigeration cycle system.

[0086] The refrigeration cycle system may include a compressor. The refrigeration cycle system may include a condenser. The refrigeration cycle system may include a drier filter. The refrigeration cycle system may include a drier filter. The refrigeration cycle system may include a capillary tube.

[0087] Components such as the compressor, condenser, filter drier, capillary tube and evaporator can be connected through pipelines.

[0088] The working process of the refrigeration cycle system may include a compression process.

[0089] The compression process is as follows: when the refrigerator has a refrigeration demand, the compressor starts working, the low-temperature, low-pressure refrigerant from the evaporator is sucked into the compressor, compressed into a high-temperature, high-pressure superheated gas in the compressor cylinder, and then discharged into the condenser.

[0090] The working process of the refrigeration cycle system may include a condensation process.

[0091] The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and it is gradually cooled into normal-temperature, high-pressure saturated steam, and further cooled into saturated liquid. The temperature no longer drops, and the pressure of the refrigerant remains almost unchanged during the entire condensation process.

[0092] The working process of the refrigeration cycle system may include a throttling process.

[0093] The throttling process is as follows: the condensed refrigerant saturated liquid passes through a drying filter to remove moisture and impurities and then flows into the capillary tube, where it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure.

[0094] The working process of the refrigeration cycle system may include an evaporation process.

[0095] The evaporation process is as follows: wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat to vaporize, lowering the temperature of the evaporator and its surroundings, cooling the storage compartment, and turning the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor again, repeating the above process, converting energy through the change in the state of the refrigerant, transferring the heat in the refrigerator to the air outside the box, thereby realizing the refrigerator's refrigeration cycle.

[0096] In some embodiments of the present application, the door body 2 may include a door body shell.

[0097] The door body 2 may include a door body liner. The door body liner may be arranged on a side of the door body close to the box body.

[0098] The door body shell may include a door panel. The door panel may be arranged on a side of the door body away from the box body. The door panel may be arranged opposite to the door body inner liner.

[0101] The shelf device can be folded and placed in the storage space. When it is necessary to make room, the shelf device can be folded up.

[0102] At present, after the shelf device is folded, it is usually necessary to set a fixing device to keep the shelf device in the folded state. However, when the shelf device is changed from the flat state to the folded state, the shelf device and the fixing device need to be fixed, and when the shelf device is changed from the folded state to the flat state, the shelf device and the fixing device need to be unlocked. Therefore, it is necessary to constantly fix and unlock, which increases the operation steps, makes the user operation complicated, and also requires additional setting of the fixing part, which increases the raw material cost and the assembly cost.
