[0047] Combination Figure 1-6As shown, the embodiment of the present disclosure provides a refrigerator, including an inner tank 100 and an air duct assembly 300. The inner tank 100 is pre-buried with a hanging base 200, and a clamping block 230 is provided at the front end of the hanging base 200, and the clamping block 230 is located in the inner tank 100; the air duct assembly 300 is arranged in the inner tank 100, including an air duct cover plate 310; and the air duct cover plate 310 is provided with a clamping slot 320, the clamping slot 320 corresponds to the clamping block 230, and the air duct cover plate 310 is hung on the clamping block 230 through the clamping slot 320.

[0048] In this embodiment, the inner liner 100 is pre-embedded with the hanging base 200 during the molding process, and the front end block 230 of the hanging base 200 is located in the inner liner 100. When installing the air duct assembly 300, the slot 320 of the air duct cover 310 is hung on the block 230 to achieve the connection between the air duct cover 310 and the inner liner 100. In this way, the installation process of the air duct assembly 300 is very convenient, which improves the production efficiency. In addition, compared with the method of fixing with buckles, the hanging structure composed of the slot 320 and the block 230 used in this embodiment is simple, and there is no need to repeatedly change the mold due to the adaptation problem of the buckle, which reduces the production cost.

[0049] Optionally, the refrigeration system of the refrigerator is mainly composed of a compressor, a condenser, a filter, a capillary tube, an evaporator, etc. The refrigeration principle of the refrigerator is mainly to achieve refrigeration by utilizing the conversion between the gas and liquid states of the refrigerant and the absorption and release of heat.

[0050] In this embodiment, when the refrigerant is sucked in and compressed by the compressor, it will become a high-temperature and high-pressure superheated vapor, and then be discharged from the exhaust pipe. After these high-temperature and high-pressure superheated vapors enter the condenser, they will dissipate heat to the surrounding air and condense into low-temperature and high-pressure gas. These low-temperature and high-pressure gases are filtered by the drying filter and enter the capillary tube. In the capillary tube, due to the slender and obstructed passage, these gases are throttled and reduced in pressure to become low-temperature and low-pressure liquids. After these low-temperature and low-pressure liquids enter the evaporator, they will absorb a large amount of external heat and vaporize into dry saturated steam, and bring the cold into the refrigerator through the air duct assembly 300 to achieve the refrigeration effect. Finally, these refrigerants become low-pressure superheated vapor again and are sucked in by the compressor, and then the next round of refrigeration process begins.

[0051] Alternatively, if Figure 1 As shown, the inner container 100 includes a first inner wall 110, and the first inner wall 110 faces the door of the inner container 100. In addition, the mounting base 200 is pre-buried on the first inner wall 110, and the block 230 at the front end of the mounting base 200 faces the door of the inner container 100. In this way, the air duct assembly 300 is installed on the first inner wall 110.

[0052] In this embodiment, during installation, the air duct assembly 300 is first inserted into the inner container 100 from the door, and then the clamping slot 320 of the air duct cover plate 310 is hung on the clamping block 230, so that the air duct cover plate 310 and the first inner wall 110 can be connected. In addition, the air duct cover plate 310 can be further fixed to the first inner wall 110 with screws, thereby strengthening the connection strength of the air duct assembly 300.

[0053] Optionally, the first inner wall 110 is a plane. In this way, after the air duct cover plate 310 is installed on the first inner wall 110, the space required for installation can be reduced, thereby increasing the refrigeration capacity of the inner container 100.

[0054] Alternatively, if Figure 1 As shown, the inner liner 100 further includes a second inner wall 120 and a third inner wall 130, wherein the first inner wall 110 faces the door of the inner liner 100, and the second inner wall 120 and the third inner wall 130 are respectively connected to the left and right sides of the first inner wall 110. According to the arrangement requirements of the air duct assembly 300, a hanging base 200 is pre-embedded on the corresponding inner wall of the inner liner 100.

[0055] For example, when the air duct assembly 300 needs to be arranged on the second inner wall 120, the hanging base 200 is pre-embedded on the second inner wall 120, and the clamping block 230 at the front end of the hanging base 200 faces the third inner wall 130. When installing in this way, the air duct assembly 300 is first extended into the inner tank 100 from the door, and then the clamping slot 320 of the air duct cover plate 310 is hung on the clamping block 230, so that the air duct assembly 300 is installed on the second inner wall 120. In addition, the air duct cover plate 310 can be further fixed to the second inner wall 120 by screws, so as to strengthen the connection strength of the air duct assembly 300.

[0056] In another exemplary embodiment, when the air duct assembly 300 needs to be arranged on the third inner wall 130, the third inner wall 130 is pre-embedded with the hanging base 200, and the clamping block 230 at the front end of the hanging base 200 faces the second inner wall 120. When installing in this way, the air duct assembly 300 is first extended into the inner tank 100 from the door, and then the clamping slot 320 of the air duct cover plate 310 is hung on the clamping block 230, so that the air duct assembly 300 is installed on the third inner wall 130. In addition, the air duct cover plate 310 can be further fixed to the third inner wall 130 by screws, thereby strengthening the connection strength of the air duct assembly 300.

[0057] Optionally, the second inner wall 120 is a plane. In this way, after the air duct cover plate 310 is installed on the second inner wall 120, the space required for installation can be reduced, thereby increasing the refrigeration capacity of the inner container 100.

[0058] Optionally, the third inner wall 130 is a plane. In this way, after the air duct cover plate 310 is installed on the third inner wall 130 , the space required for installation can be reduced, thereby increasing the refrigeration capacity of the inner container 100 .

[0059] Alternatively, if Figure 2 As shown, the inner container 100 is recessed outward to form a receiving groove 140 ; ​​a fixing seat 210 is provided at the rear end of the hanging base 200 , and the fixing seat 210 is pre-buried in the receiving groove 140 .

[0060] In this embodiment, since the receiving groove 140 is formed by the inner liner 100 being recessed to the outside, the receiving groove 140 does not occupy the refrigeration space of the inner liner 100, thereby improving the space utilization of the inner liner 100. In addition, since the wall thickness of the inner liner 100 is relatively thin, the provision of the receiving groove 140 provides a pre-embedded position for the fixing seat 210. At the same time, the fixing seat 210 is pre-embedded in the receiving groove 140, which can also improve the stability of the hanging base 200.

[0061] Alternatively, if Figure 3 As shown, the fixing seat 210 includes a first seat body 211 and a second seat body 212. The first seat body 211 is configured as a column; the second seat body 212 is configured as a column, the bottom surface of the second seat body 212 is arranged close to the top surface of the first seat body 211, and the diameter of the second seat body 212 is smaller than the diameter of the first seat body 211.

[0062] In this embodiment, the fixing seat 210 is composed of two connecting seats. Figure 2 As shown, the first seat body 211 is close to the bottom of the receiving groove 140, and the second seat body 212 is close to the notch of the receiving groove 140. When the fixing seat 210 is embedded in the inner liner 100, it can form more contact area with the inner liner 100, so as to improve the connection strength between the hanging base 200 and the inner liner 100. Preferably, the first seat body 211 and the second seat body 212 are both constructed in a cylindrical shape, which is conducive to the fixing seat 210 being subjected to a more uniform force when the clamping block 230 hangs the air duct cover plate 310. Moreover, the diameter of the second seat body 212 is smaller than the diameter of the first seat body 211, which is conducive to making the fixing seat 210 more stable.

[0063] Optionally, the height of the second base body 212 is greater than the height of the first base body 211 .

[0064] Optionally, the first seat body 211 and the second seat body 212 are integrally formed. Such an integrally formed design improves the structural stability of the fixing seat 210 and avoids problems such as loosening or falling off caused by separation of the seat bodies.

[0065] Optionally, a limiting column 220 is provided on the side of the first seat body 211, and / or a limiting column 220 is provided on the side of the second seat body 212. In this way, the limiting column 220 can not only further increase the contact area between the fixed seat 210 and the inner liner 100, but also effectively prevent the first seat body 211 and the second seat body 212 from rotating. Preferably, the limiting column 220 is configured as a quadrangular prism.

[0066] Optionally, after the fixing seat 210 is pre-buried in the receiving groove 140 , the limiting column 220 is horizontally arranged.

[0067] Optionally, the number of the limiting posts 220 is two.

[0068] Exemplarily, two limiting posts 220 are respectively disposed on both sides of the first seat body 211, and the second seat body 212 is not provided with limiting posts 220. Alternatively, the first seat body 211 is not provided with limiting posts 220, and two limiting posts 220 are respectively disposed on both sides of the second seat body 212.

[0069] Another exemplary example is, Figure 3 As shown, two limiting posts 220 are respectively arranged on both sides of the first base 211, and two limiting posts 220 are respectively arranged on both sides of the second base 212. The projection of the limiting posts 220 on the second base 212 on the first base 211 is located on the first base 211.

[0070] Optionally, the number of the limiting posts 220 is four.

[0071] Exemplarily, four limiting posts 220 are respectively arranged at four equal parts of the first seat body 211, and the second seat body 212 is not provided with limiting posts 220. Alternatively, the first seat body 211 is not provided with limiting posts 220, and four limiting posts 220 are respectively arranged at four equal parts of the second seat body 212.

[0072] In another exemplary embodiment, four limiting posts 220 are respectively arranged at four equal parts of the first seat body 211, and four limiting posts 220 are respectively arranged at four equal parts of the second seat body 212. The projection of the limiting posts 220 on the second seat body 212 on the first seat body 211 is located on the first seat body 211.

[0073] Optionally, the block 230 is configured as a column, and the diameter of the block 230 is equal to the diameter of the second seat body 212 .

[0074] In this embodiment, preferably, the block 230 is constructed in a cylindrical shape, which is conducive to a more uniform force when the block 230 is hung on the air duct cover 310. In addition, the diameter of the block 230 is equal to the diameter of the second base body 212, which is conducive to making the overall structure of the hanging base 200 more stable.

[0075] Optionally, the height of the block 230 is equal to the height of the first base 211 .

[0076] Optionally, the opening of the card slot 320 is arranged downward, and the card block 230 extends into the card slot 320 from bottom to top.

[0077] In this embodiment, since the card block 230 is inserted into the card slot 320 from bottom to top, it is easier to align the card slot 320 and insert it smoothly. This design simplifies the installation process and reduces the difficulty of operation. When the card block 230 is fully inserted into the card slot 320, due to the effect of gravity, the card block 230 will naturally be positioned in the card slot 320. This design can improve the positioning accuracy and ensure the stable connection between the card block 230 and the card slot 320.

[0078] Optionally, reinforcing ribs are provided outside the slot 320. In this way, the structural strength of the slot 320 can be effectively enhanced by providing the reinforcing ribs, making the slot 320 more solid and better able to resist external impact and pressure.

[0079] Alternatively, if Figure 3 As shown, the block 230 is connected to the top surface of the second base body 212 via a connecting column 240 .

[0080] In this embodiment, since the fixing seat 210 is pre-buried in the receiving groove 140, in order to make the block 230 at the front end of the hanging base 200 extend into the inner tank 100 by a certain distance, the block 230 is connected to the top surface of the second seat body 212 through the connecting column 240. This makes it easy to insert the block 230 into the slot 320 of the air duct cover 310 when installing the air duct assembly 300.

[0081] Optionally, the connecting column 240 is configured as a column. Preferably, the connecting column 240 is cylindrical, and the diameter of the connecting column 240 is smaller than the diameter of the second seat body 212 .

[0082] Optionally, the height of the connecting column 240 is greater than the height of the second base body 212 .

[0083] Alternatively, if Figure 4 As shown, the slot 320 has a first slot wall 321 facing the hanging base 200 and a supporting notch 322 . When the block 230 extends into the slot 320 , the connecting column 240 is located in the supporting notch 322 .

[0084] In this embodiment, since the block 230 is connected to the top surface of the second base body 212 via the connecting column 240, when the block 230 extends into the slot 320, the connecting column 240 interferes with the first slot wall 321, making it difficult for the block 230 to fully penetrate into the slot 320. Figure 5As shown, under the effect of the supporting notch 322, when the block 230 is inserted into the slot 320, the connecting column 240 is located in the supporting notch 322, so that the block 230 can be fully inserted into the slot 320. In addition, the connecting column 240 supports the cover plate upward, and the connecting column 240 and the block 230 are used to hang the air duct cover plate 310 at the same time, thereby improving the stability of the hanging base 200.

[0085] Optionally, the shape of the supporting notch 322 matches the cross section of the connecting column 240 .

[0086] For example, Figure 5 As shown, the connecting column 240 is cylindrical, and its cross section is circular. The supporting notch 322 is an arc with its opening facing downward, and the side surface of the connecting column 240 can be close to the inner wall surface of the supporting notch 322. In this way, it is helpful to reduce the shaking of the connecting column 240 in the supporting notch 322.

[0087] Optionally, the first slot wall 321 is further provided with an avoidance notch 323 , which is connected to the supporting notch 322 and is located below the supporting notch 322 ; moreover, the card block 230 can extend into the card slot 320 through the avoidance notch 323 , and the connecting column 240 can extend into the supporting notch 322 through the avoidance notch 323 .

[0088] In this embodiment, since the first slot wall 321 faces the hanging base 200, and the card block 230 needs to extend into the slot 320 from bottom to top, the card block 230 is likely to interfere with the first slot wall 321 when extending into the slot 320. Under the effect of the avoidance notch 323, the interference between the card block 230 and the first slot wall 321 can be reduced. The avoidance notch 323 can facilitate the card block 230 to extend into the slot 320 from the outside, greatly improving the convenience of installation and disassembly. In addition, when the card block 230 extends into the slot 320, the connecting column 240 can extend into the supporting notch 322 through the avoidance notch 323. In this way, when the connecting column 240 extends into the avoidance notch 323, the position of the air duct cover 310 can be flexibly fine-tuned, so that the card block 230 can quickly extend into the slot 320.

[0089] Optionally, the shape of the avoidance notch 323 is adapted to the cross section of the clamping block 230 .

[0090] Exemplarily, the block 230 is cylindrical, and its cross section is circular. The avoidance notch 323 is an arc with an opening facing downward, so that the block 230 can extend horizontally from the avoidance notch 323 into the notch of the slot 320 along its own axis, and then extend upward into the slot 320.

[0091] Alternatively, if Figure 6As shown, the air duct cover plate 310 is constructed in a rectangular shape, and a slot 320 is respectively provided at the four corners and the middle of the air duct cover plate 310, and a hanging base 200 corresponding to the five slots 320 is pre-embedded on the inner liner 100. In this way, each slot 320 and the corresponding block 230 form a group of hanging structures, and multiple groups of hanging structures can effectively improve the connection strength of the air duct cover plate 310.

[0092] For example, the air duct assembly 300 needs to be arranged on the first inner wall 110 of the liner 100, and the first inner wall 110 is recessed outward to form five receiving grooves 140, each receiving groove 140 corresponds to a hanging base 200, so that the hanging base 200 is pre-buried in the corresponding receiving groove 140. Then, the four corners and the middle of the air duct cover plate 310 are respectively inserted into the corresponding clamping blocks 230 of the hanging base 200, so that the air duct assembly 300 is installed on the first inner wall 110 through five sets of hanging structures.
