Figure 3 This is a schematic diagram of the structure of the box provided in this application.

[0051] See also Figures 1 to 3 The present application provides a refrigerator. The refrigerator includes a box body 1. The box body 1 may include a shell. The shell is configured as an external structure of the box body 1. The shell may form a hollow structure of a rectangular parallelepiped. It is understood that in other embodiments, the shell may also adopt a hollow structure of other shapes.

[0052] In some embodiments of the present application, a storage compartment 12 may be provided in the box body 1. The storage compartment 12 may be used to store items at low temperatures to improve the preservation effect of the items.

[0053] In some embodiments of the present application, the box body 1 may be provided with a plurality of mutually separated storage compartments 12. Each separated storage compartment 12 may be used as an independent storage space for low-temperature storage. The storage compartment 12 may be a freezer compartment. The storage compartment 12 may be a refrigerator compartment. The storage compartment 12 may meet different refrigeration requirements such as freezing and refrigeration according to different types of food materials, and perform storage.

[0054] In some embodiments of the present application, in order to meet more usage needs of people, the storage compartment 12 may also include a fresh-keeping drawer and a variable temperature chamber, etc.

[0055] A plurality of storage compartments 12 may be arranged in an upper and lower partition.

[0056] A plurality of storage compartments 12 may be arranged in a partitioned manner on the left and right.

[0057] In some embodiments of the present application, the box body 1 may be provided with a box liner 11. The box liner 11 is arranged in the outer shell. The interior of the box liner 11 is hollow. A storage compartment 12 is formed in the box liner 11. A take-in and put-out opening 13 is formed on the front side of the box liner 11. Articles can be put into the corresponding storage compartment 12 from the take-in and put-out opening 13. It is understandable that a plurality of box liner 11 may be provided in the box body 1. One or more storage compartments 12 may be formed in each box liner 11.

[0058] See also Figure 1 and Figure 2 In some embodiments of the present application, the refrigerator may include a door 2. The door 2 is movably disposed on the front side of the cabinet 1. The door 2 is configured to close the cabinet 11 so as to insulate the interior of the cabinet 11 from the outside.

[0059] In some embodiments of the present application, the door 2 may be a rotating door structure. The door 2 may be rotatably connected to a side of the box body 1 where the access opening 13 is provided. In this case, the door 2 may be used as a common door structure, such as a refrigerator door, a freezer door, etc.

[0060] Specifically, the refrigerator door 2 can be connected to the body 1 by a hinge, so that the refrigerator door 2 can rotate around the axis of the hinge to open and close the refrigerator door 2, and then open and close the corresponding storage compartment 12.

[0061] Figure 4 This is a schematic diagram of the structure of the main control board box provided in this application.

[0062] like Figure 2 and Figure 4 As shown, in some embodiments of the present application, the housing 1 may further include a main control board box 14. The main control board box 14 is disposed in an installation space (not shown in the figure) formed by the outer shell and the box 11. The main control board box 14 may be disposed at the back of the housing 1. The main control board box 14 is hollow inside and is configured as a shell for accommodating the main control board. By utilizing the hollow box-shaped shell structure of the main control board box 14, the main control board box 14 can be used to provide an installation space for the main control board. The main control board box 14 is disposed at the back of the housing 1 to facilitate the connection of the main control board with other electrical components, thereby controlling various operations of the refrigerator.

[0063] It should be noted that, in some other embodiments, the main control board box 14 may also be disposed on the top of the box body 1 or other places, which may be adjusted according to actual needs.

[0064] like Figure 4 As shown, in some embodiments of the present application, the main control board box 14 includes a box body 141 and a box cover 142 .

[0065] The box body 141 may be a rectangular hollow shell structure. A receiving cavity is provided in the box body 141. The receiving cavity is used to provide an installation space for the main control board. It is understandable that the box body 141 may also adopt a hollow shell structure of other shapes.

[0066] The top of the box body 141 is provided with an opening, and the box cover 142 is detachably connected to the opening of the box body 141, thereby enclosing a receiving cavity between the box body 141 and the box cover 142. When the box cover 142 covers the box body 141, the receiving cavity and the main control board disposed in the receiving cavity can be sealed, thereby ensuring the normal operation of the main control board and maintaining the operation of the refrigerator.

[0067] In some embodiments of the present application, a harness hole 143 may be provided on the side wall of the box body 141. The harness hole 143 may be connected to the accommodating cavity. A plurality of harness holes 143 may be provided. The harness may be connected to the main control board in the accommodating cavity through the harness hole 143, thereby realizing the connection between the main control board and other electrical components, and further realizing various operations of the refrigerator.

[0068] Figure 5 This is a schematic diagram of the structure of the power cord provided in this application. Figure 6 A schematic diagram of the structure in which a power socket of a power cord provided in an embodiment of the present application is not fixed on a power plug. Figure 7 A schematic diagram of the structure in which a power socket of a power cord provided in another embodiment of the present application is not fixed on a power plug.

[0069] like Figures 5 to 7 As shown, in some embodiments of the present application, the refrigerator includes a power cord 3. The power cord 3 is electrically connected to the box body 1. The power cord 3 may include a wire 31, a power plug 32, and a power socket 33. The wire 31 is electrically connected to the box body 1. One end of the wire 31 passes through the harness hole 143 and is connected to the main control board. The other end of the wire 31 is connected to the power plug 32. By connecting the power cord 3 to an external power source, the main control box can be powered on.

[0070] Figure 8 This is a schematic diagram of the structure of a power socket provided in an embodiment of the present application. Fig. 9 A schematic diagram of the structure of a power socket provided in another embodiment of the present application.

[0071] like Figure 8 and Fig. 9As shown, the power socket 33 can be electrically connected to the power plug 32. The power socket 33 can have a socket hole 331. The external power line 3 can be connected to the socket hole 331.

[0072] The electric control panel is arranged at the back of the box 1, and the power cord 3 is connected to the box 1 from the back of the box 1, which can avoid too many cables on the front or side of the refrigerator, and keep the appearance of the refrigerator neat and beautiful. In addition, the power cord 3 is connected at the back of the box 1, which is more convenient to connect to the external power socket on the wall, does not affect the placement of the refrigerator, and can prevent users from touching the power cord 3, reducing the risk of accidental electric shock and improving safety.

[0073] In some embodiments of the present application, the socket holes 331 on the power socket 33 are distributed in a Y-shaped structure, which is suitable for opening holes of various plugs and can avoid problems such as wire crossing and wire entanglement.

[0074] like Figure 8 As shown, in some embodiments of the present application, the power socket 33 can be configured in a step-like shape, occupying less space.

[0075] like Fig. 9 As shown, in some embodiments of the present application, the power socket 33 can be set to a cylindrical shape, and the power plug 32 can be set to a cylindrical shape. The power socket 33 and the power plug 32 can be set to have the same outer diameter, so that no matter how much the power socket 33 rotates around its axis, the power socket 33 and the power plug 32 can still form a cylindrical shape, thereby improving the integrity of the connection between the power socket 33 and the power plug 32.

[0076] The socket hole 331 can be configured as a deformable socket hole 331, which is more convenient for connection and removal with a plug.

[0077] The power socket 33 can rotate relative to the power plug 32, thereby changing the direction of the socket hole 331 on the power socket 33, so that the power socket 33 can be more conveniently connected to the external power cord 3 located in different directions, avoiding the entanglement of the wires 31 to adapt the direction of the socket hole 331.

[0078] like Figure 6 and Figure 7As shown, in some embodiments of the present application, the power cord 3 may include a flexible conductive member 34. The flexible conductive member 34 is disposed between the power plug 32 and the power socket 33. One end of the flexible conductive member 34 is electrically connected to the power plug 32, and the other end of the flexible conductive member 34 is electrically connected to the power socket 33, so that power can be supplied between the power plug 32 and the power socket 33. Electrical pins are respectively disposed on the power socket 33 and the power plug 32, and one end of the flexible conductive member 34 can be welded to the electrical pin of the power socket 33, and the other end of the flexible conductive member 34 can be welded to the electrical pin of the power plug 32.

[0079] When the power socket 33 rotates, the flexible conductive member 34 will twist. The flexible material has good deformation and recovery capabilities, and can bend and twist when the power socket 33 rotates, and return to its original state after the power socket 33 rotates to its original position.

[0080] In some embodiments of the present application, the flexible conductive member 34 may be a compression spring. The compression spring is usually made of metal materials, such as copper, aluminum, etc., which have good electrical conductivity, can effectively conduct current, and ensure the normal operation of the circuit. The metal material has high wear resistance, and the compression spring has good elastic recovery ability, can quickly return to its original state after being stressed, and can maintain good electrical conductivity for a long time.

[0081] In some embodiments of the present application, the flexible conductive member 34 may be a copper braided wire. Copper is an excellent conductive material with low resistivity and good electrical conductivity, and can effectively conduct current to ensure smooth circuits. Copper also has good thermal conductivity, and the copper braided wire can effectively dissipate heat to avoid overheating. The copper braided wire is generally surface-treated and has good antioxidant properties, and can resist the influence of environmental factors such as oxidation and corrosion. In addition, the copper braided wire is interwoven with multiple strands of fine copper wires, has good flexibility and bendability, can withstand the torsion caused by multiple rotations of the power socket, and can effectively resist wear and friction, has a long service life, and maintains stable conductive properties.

[0082] Fig.10 This is a schematic diagram of the structure of the power plug provided in this application.

[0083] like Fig.10 As shown, in some embodiments of the present application, a receiving cavity 322 may be provided on the side of the power plug 32 facing the power socket 33, and a flexible conductive member 34 may be provided in the receiving cavity 322, so that the power socket 33 can be fixed on the power plug 32 to form an integrated structure, thereby improving the safety of the power cord 3.

[0084] Fig.11A schematic diagram of the relative positions of the first mark and the second mark when the power plug and the power socket provided in the present application are in the original position. Fig.12 This is a schematic diagram of the relative positions of the first mark and the second mark after the power plug and the power socket provided in the present application are rotated.

[0085] like Fig.11 and Fig.12 As shown, in some embodiments of the present application, a first mark 323 is provided on the side wall of the power plug 32, and a second mark 333 is provided on the side wall of the power socket 33. When the power plug 32 and the power socket 33 are in the original position, the positions of the first mark 323 and the second mark 333 are correspondingly set. Through the indication of the first mark 323 and the second mark 333, the relative position between the power socket 33 and the power plug 32 can be intuitively obtained, so that when the direction of the socket hole 331 is adjusted multiple times, the power socket 33 will not rotate in one direction all the time, thereby avoiding excessive twisting of the flexible conductive member 34 connected between the power socket 33 and the power plug 32, which affects the service life of the power cord 3.

[0086] For example, the first mark 323 may be an arrow indicating a clockwise direction, and the second mark 333 may be an arrow indicating a counterclockwise direction. When the power plug 32 and the power socket 33 are in the initial position, the first mark 323 is located below the second mark 333, and the indication direction of the first mark 323 is opposite to the indication direction of the second mark 333.

[0087] When the orientation of the socket hole 331 needs to be adjusted, if the first mark 323 and the second mark 333 are in the original position, the power socket 33 is rotated counterclockwise to move the second mark 333 to a suitable position facing away from the first mark 323. If the first mark 323 and the second mark 333 are not in the original position, and the directions indicated by the first mark 323 and the second mark 333 are opposite to each other, the power socket 33 can be rotated clockwise to a suitable position. If the first mark 323 and the second mark 333 are not in the original position, and the directions indicated by the first mark 323 and the second mark 333 are facing each other, the power socket 33 can be rotated counterclockwise to a suitable position.

[0088] Fig.13 This is a schematic diagram of the connection structure of the power plug and power socket provided in this application.

[0089] like Fig.10 and Fig.13As shown, in some embodiments of the present application, a first connecting portion 321a / 321b may be provided on the power plug 32, and a second connecting portion 332a / 332b may be provided on the power socket 33. The first connecting portion 321a / 321b and the second connecting portion 332a / 332b are correspondingly connected so that the power socket 33 can be fixed on the power plug 32, so that the power socket 33 and the power plug 32 can form an integrated structure, thereby improving the integrity of the power plug 32 and the power socket 33, thereby improving the safety of use of the power cord 3.

[0090] like Fig.10 As shown, in some embodiments of the present application, the first connection portion 321a / 321b can be set as a first magnet 321b. The first magnet 321b is arranged in the accommodating cavity 322. The second connection portion 332a / 332b can be set as a second magnet 332b. The first magnet 321b and the second magnet 332b can attract each other. The side of the first magnet 321b close to the second magnet 332b can be set as an S pole, and the side of the second magnet 332b close to the first magnet 321b can be set as an N pole; or the side of the first magnet 321b close to the second magnet 332b can be set as an N pole, and the side of the second magnet 332b close to the first magnet 321b can be set as an S pole; in this way, when the first magnet 321b and the second magnet 332b are close to each other, the power socket 33 can be fixed on the power plug 32.

[0091] It is understandable that the mutual attraction between the first magnet 321b and the second magnet 332b can overcome the elastic force generated by the flexible conductive member 34 returning to its original state, thereby ensuring that the power socket 33 and the power plug 32 can be stably connected.

[0092] like Fig.13 As shown, in some other embodiments of the present application, the first connection portion 321a / 321b is formed on the side of the power plug 32 facing the power plug 32. The second connection portion 332a / 332b is formed on the side of the power socket 33 facing the power plug 32. The first connection portion 321a / 321b can be set as a card block 332a, and the second connection portion 332a / 332b can be provided with a plurality of card slots 321a, and the card block 332a can be connected to any card slot 321a. The plurality of card slots 321a are arranged circumferentially along the surface where they are distributed, so that after the power socket 33 is rotated, the card block 332a can always be connected to the card slot 321a, thereby realizing the connection between the power plug 32 and the power socket 33.

[0093] In some other embodiments of the present application, the first connection portion 321a / 321b may be provided with a plurality of slots 321a, and the plurality of slots 321a are distributed circumferentially along the first connection portion 321a / 321b, and the second connection portion 332a / 332b may be provided as a block 332a. After the power socket 33 is rotated, the block 332a can still be engaged in any slot 321a.

[0094] like Figures 5 to 7 As shown, in some embodiments of the present application, the power cord 3 may further include a dust cover 35. The dust cover 35 may be hinged to the peripheral wall of the power socket 33, so that the dust cover 35 is configured as a flip cover structure.

[0095] The dust cover 35 can also be movably connected to the power socket 33 . The dust cover 35 covers the power socket 33 to seal the socket hole 331 on the power socket 33 , thereby improving the safety and dustproofness of the power socket 33 .

[0096] To summarize, the present application connects the power socket 33 and the power plug 32 through a flexible conductive part 34, so that the power socket 33 can rotate relative to the power plug 32, thereby changing the orientation of the socket hole 331 on the power socket 33, improving the convenience of using the power socket 33, and avoiding the problem of entanglement of the wires 31.

[0097] In addition, a first connecting portion 321a / 321b is provided on the power plug 32, and a second connecting portion 332a / 332b is provided on the power socket 33. The power plug 32 and the power socket 33 can be connected through the first connecting portion 321a / 321b and the second connecting portion 332a / 332b, thereby connecting the power plug 32 and the power socket 33 together, thereby improving the integrity and safety of the power cord 3, thereby improving the safety of use of the refrigerator.
