[0099] The box opening 1061 is a placement opening for items, and items can be placed in the accommodating cavity through the box opening.

[0100] In this application, reference is made to Figure 1-Figure 2 The refrigerator may include a door body 200. The door body 200 may be used to open or close the cabinet opening.

[0101] The door body 200 can be rotatably connected to the box body. The rear end of the door body 200 can be rotatably connected to the box body. The door body flips so that the door body switches from closing the box body opening to opening the box body opening.

[0102] When the door body 200 opens the box opening, the front end of the door body can gradually move backwards.

[0103] In this application, reference is made to Figure 1-Figure 2The housing may include a shell 102 .

[0104] The box body may include an inner liner 101. The inner liner 101 may be arranged in the outer shell. Articles may be placed in the inner liner 101.

[0105] A first heat exchanger cavity 1062 is provided in the inner tank 101 .

[0106] In the present application, the refrigerator may include a first heat exchanger, which may be an evaporator 300 .

[0107] The first heat exchanger can be arranged in the inner tank. The first heat exchanger can be used for exchanging heat with air. The first heat exchanger can be arranged in the first heat exchanger cavity.

[0109] In this application, reference is made to Figure 3-Figure 6 , the length direction of the first heat exchanger can be parallel to the front-to-back direction of the box body.

[0110] In this application, reference is made to Figure 3-Figure 6 The refrigerator may include a fan 700. The fan 700 is used to provide power for the flow of air.

[0111] The fan 700 may be disposed in the inner tank. The fan 700 may be disposed on one side of the first heat exchanger.

[0112] The fan 700 may be disposed at one side of the first heat exchanger in the front-rear direction. The fan 700 may be disposed in front of the first heat exchanger. The fan 700 may be disposed behind the first heat exchanger.

[0118] In this application, reference is made to Figure 8-Figure 9 The refrigerator may include a water receiving tray 810. The water receiving tray may be arranged in the inner container. The water receiving tray may be arranged below the first heat exchanger to receive condensed water on the first heat exchanger.

[0119] In some refrigerators on the market, the heat exchanger is directly placed on the water receiving tray. The condensed water flowing from the heat exchanger to the water receiving tray will be blocked by the bottom of the heat exchanger, which is not conducive to the collection of the condensed water and the outflow of the water receiving tray. Therefore, the present application proposes a refrigerator that is convenient for water collection and drainage.

[0120] In the present application, a plane that is vertically arranged and perpendicular to the front-to-back direction of the box is defined as a first plane M1.

[0125] Along the length direction of the box body, the inclination direction of the first water receiving surface may be the same as the inclination direction of the bottom surface of the heat exchanger.

[0126] The intersection line of the plane where the first water-connecting surface is located and the first plane may be a second intersection line. The angle between the second intersection line and the horizontal plane may be a second angle β.

[0127] β>α is set so that the inclination angle of the first water receiving surface is greater than the inclination angle of the bottom surface of the heat exchanger, thereby avoiding obstruction of the flow of condensed water by the bottom end of the heat exchanger, facilitating the rapid accumulation of condensed water and the discharge of condensed water.

[0128] In the present application, α> the first parameter value. The first parameter value may be 2°, 4°, or 6°. The bottom surface of the heat exchanger can be tilted so that the condensed water on the first heat exchanger flows toward the lowest point of the first heat exchanger, which facilitates the collection of the condensed water.

[0129] In the present application, α<the second parameter value. The second parameter value may be 20°, 22°, or 24°. Avoid excessive tilting of the bottom end of the first heat exchanger, reduce the space occupied by the bottom end of the first heat exchanger in the vertical direction, and ensure the volume of the accommodating cavity of the refrigerator.

[0130] In the present application, the bottom surface of the heat exchanger can be arranged horizontally along the front-rear direction of the box body to avoid excessively increasing the height of the first heat exchanger in the vertical direction and reduce the space occupied by the first heat exchanger in the inner tank.

[0144] In this application, reference is made to Figure 10-Figure 14 The second water receiving surface may be formed with a heat exchanger support portion 810123. The heat exchanger support portion may be formed by an upward protrusion on the second water receiving surface.

[0145] The first heat exchanger may be disposed on the heat exchanger support portion.

[0146] In this application, reference is made to Figure 15-17 The inner liner may include an inner liner first support surface 101231 located below the first water receiving surface.

[0186] The compression process is as follows: the compressor starts working, low-temperature, low-pressure refrigerant is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the compressor cylinder, and then discharged into the condenser.

[0187] The working process of the refrigeration system may include a condensation process.

[0188] 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 to a saturated vapor at room temperature and high pressure, and further cooled to a saturated liquid. The temperature no longer drops. The temperature at this time is called the condensation temperature. The pressure of the refrigerant remains almost unchanged during the entire condensation process.

[0189] The working process of the refrigeration system may include a throttling process.

[0191] The working process of the refrigeration system may include an evaporation process.

[0192] The evaporation process is as follows: wet steam at room temperature and low pressure begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator passes through the gas-liquid separator and returns to the compressor again, repeating the above process to transfer the heat in the freezer to the air outside the freezer, thus achieving the purpose of refrigeration.
