[0044] In addition, in the description of the present application, the expression "A and / or B" represents all possible combinations of A and B, such as only A, only B, or A and B.

[0045] The embodiments of the present application only use a refrigerator as an example to schematically illustrate the implementation methods of the present application. It can be understood that the corresponding implementation methods can also be applied to other refrigeration appliances 100 such as freezers and wine cabinets, and can achieve the same technical effects.

[0046] Figure 1 The schematic diagram shows a partial front view of a preferred refrigeration appliance 100 of the present application. It is understood by those skilled in the art that the refrigeration appliance 100, such as a refrigerator, generally has an insulated box body and a door body, and the box body includes an outer shell, an inner shell, and an insulating layer located between the two. Figure 1 The housing of the refrigeration appliance 100 defines a plurality of heat-insulated storage chambers for storing food and other items. Therefore, a communicating air duct is provided between the plurality of storage chambers to facilitate the temperature control of each storage chamber. In an illustrative embodiment of the present application, the storage chambers include a refrigerating chamber on the right side of the refrigerator and a freezing chamber on the left side. The storage chambers are suitable for accommodating one or more storage containers; and the storage chambers can be closed by respective corresponding appliance doors (not shown).

[0047] It should be understood that the present invention should not be limited to the specific distribution of the storage compartments of the refrigerator. The present invention can also be applied to other forms of refrigerators, such as refrigerators with a refrigeration compartment and a freezer compartment distributed up and down, a refrigerator with a variable temperature chamber between the refrigeration compartment and the freezer compartment, a double-door refrigerator with storage compartments arranged side by side, and a refrigerator with drawer doors and / or French double doors.

[0048] The refrigeration appliance 1000 has an evaporative refrigeration system that forms a closed loop. The refrigeration system at least includes a compressor (not shown), a condenser (not shown), a throttling device (not shown) and an evaporator (not shown). In view of the fact that such a refrigeration system is a well-known technology in the prior art, further description thereof is omitted. Of course, the refrigeration appliance 1000 can also use other forms of refrigeration systems (such as absorption refrigeration systems, thermoelectric refrigeration systems).

[0049] For brevity, Figure 1 Most of the components of the internal space formed by the door body, refrigeration system, shell, foam material, and liner are hidden to facilitate the explanation of the inventive concept of the utility model. Regarding the implementation method of hiding this part, any existing method can be referred to.

[0050] See attached Figure 1 The refrigeration appliance 100 includes an inner container, and the inner container 10 has an inner surface 11 forming an inner space 20 . Figure 1 In the exemplary embodiment, the refrigeration appliance 100 includes a freezer compartment 101 as a first storage compartment and a refrigerator compartment 102 as a second storage compartment, and the freezer compartment 101 and the refrigerator compartment 102 are distributed on the left and right.

[0051] Figure 2 A partial rear view of a refrigeration appliance of a preferred embodiment is shown, Figure 3 Shows Figure 1 A cross-sectional view of the refrigeration appliance in the height direction is shown, Figure 4 Shows Figure 1 A cross-sectional view of a local area A of the refrigeration appliance, Figure 5 Shows Figure 1 Exploded three-dimensional diagram of the air duct and cold storage room. Figure 6 A perspective view of an air duct is shown.

[0052] Combination Figure 1-6 It can be known that the refrigeration appliance 100 includes an air duct 30 fixed on the outer side of the inner container 10 , and the air duct 30 provides a path for the fluid in the refrigeration appliance 100 to flow.

[0053] The air duct 30 includes a main body 31 for fluid circulation and a mounting portion 32 for connecting the air duct 30 to the inner container 10 .

[0054] Further, the air duct 30 is arranged between the inner tanks 10 of the two storage chambers so that the fluid can flow from one storage chamber to another storage chamber. Thus, the mounting portion 32 may include a first mounting portion 32a connected to the inner tank of one storage chamber of the refrigeration appliance 100 and a second mounting portion 32b connected to the inner tank of the other storage chamber.

[0055] In such Figure 1In the specific embodiment shown, one end and the other end of the air duct 30 are respectively connected to the two opposite side walls of the inner liner of the freezer chamber 101 and the inner liner of the refrigerator chamber 102 to provide a channel for fluid circulation between the freezer chamber 101 and the refrigerator chamber 102.

[0056] In one or more embodiments, the first mounting portion 32a and the second mounting portion 32b at both ends of the air duct 30 are not completely identical in structure to facilitate better connection with the freezer compartment and the refrigerator compartment, respectively.

[0057] The mounting portion 32 includes an abutment portion 33 disposed at the end of the air duct 30 and matching the shape of the outer surface 12 of the inner liner 10. The abutment portion 33 provides an abutment surface matching the shape of the outer surface 12 of the inner liner 10 to improve the sealing reliability between the air duct 30 and the inner liner.

[0058] The mounting portion 32 includes a connecting portion 34 , and the connecting portion 34 cooperates with the abutting portion 33 to restrict the inner container 10 between the abutting portion 33 and the connecting portion 34 .

[0059] When the air duct 30 is assembled to the inner liner 10, the connecting portion 34 protrudes from the inner surface 11 of the inner liner 10 to restrict the inner liner 10 between the abutting portion 33 and the connecting portion 34. In this way, the air duct 30 is fixed to the inner liner through the abutting portion 33 and the connecting portion 34 at the end of the air duct 30, and the air duct 30 and the inner liner 10 are matched and fitted in shape while the inner liner 10 is clamped between the abutting portion 33 and the connecting portion 34. The connection and assembly are simple and reliable, and the operation is convenient, which is conducive to improving the assembly efficiency and quality of the air duct 30 and the inner liner 10.

[0060] In order to facilitate the stable connection of the air duct 30 to the inner liner 10 , the abutting portion and the connecting portion are designed in pairs on the mounting portion 32 .

[0061] Furthermore, the air duct 30 is disposed at the rear of the inner container to facilitate the design of the fluid channel in the inner space 20, thereby making full use of the inner space 20. Figure 4 As shown, at least one internal air duct 50 in fluid communication with the air duct 30 is provided in the internal space 20, and a avoiding portion 51 is provided at the connection end of the internal air duct 50 and the air duct to avoid the connection portion protruding from the inner surface 11 of the inner liner 10. In this way, the connection and sealing of the air duct assembly in the internal space 20 are facilitated.

[0062] Figure 7 shows a top view of the air duct, combined with Figure 3 As shown, the depth of the freezing chamber 101 is smaller than that of the storage chamber 102 , and the main body 31 includes a horizontal section 311 and an inclined section 312 , so as to facilitate the air duct 30 to connect the freezing chamber 101 and the refrigerating chamber 102 .

[0063] The horizontal section 311 is connected to the inner tank of the refrigerator compartment 102 with a large depth, and the inclined section 312 is connected to the inner tank of the freezer compartment 101 with a small depth, which can help to fully utilize the space in the refrigeration appliance.

[0064] The main body 31 of the air duct 30 is provided with an air duct assembly for opening or closing the air duct 30. Preferably, the air duct assembly 40 is provided in one end of the air duct 30 close to the refrigerating chamber 102. In this way, it is helpful to prevent the air duct from freezing and failing to work normally.

[0065] The damper assembly 40 includes a damper 41 for opening or closing a fluid passage defined by the air duct 30 , a driving unit 42 for driving the damper 41 to move, and a cable 43 connecting the driving unit.

[0066] A connector 13 plugged into the cable 43 is provided on the rear wall of the inner tank 10 , and the connector is located on the rear wall near the damper assembly 40 .

[0067] The outer surface of the main body 31 is provided with a plurality of integrally formed reinforcing ribs 315 to increase the strength of the air duct 30. Preferably, the main body 31, the reinforcing ribs 315 and the mounting portion 32 of the air duct 30 are integrally formed.

[0068] The main body 31 is provided with a step portion 313 for positioning the damper assembly 40 and a buckle portion 314 for fixing the damper assembly, which is provided on the inner wall of the main body 31 and is close to the mounting portion 32 relative to the step portion 313. The damper assembly 40 is engaged in the main body by the buckle portion 314 through a frame 44.

[0069] Figure 8 A cross-sectional view of the air duct viewed from the rear is shown, combined with Figure 7 It can be seen that the abutting portion 33 is configured as a flange portion 331 extending from the end of the main body portion 31 . The inner liner 10 is provided with a hole 13 for installing the air duct 30 , and the flange portion 331 abuts against the peripheral wall of the hole 13 .

[0070] In a preferred embodiment, the flange portion 331 is formed at the periphery of the end of the main body portion 31 , thereby being able to better fit and abut against the peripheral wall of the hole 13 to facilitate the sealing of the air duct 30 and the inner tank 10 .

[0071] The connecting portion 34 is configured as a clamping portion 341 extending from the inner side of the flange portion 331 in a direction away from the main body portion 31. This is beneficial to the molding and manufacturing of the abutting portion 33 and the connecting portion 34.

[0072] In order to better connect with the clamping portion 341 , a tongue portion 15 is provided on the peripheral wall of the hole 13 at a position corresponding to the clamping portion 341 . The tongue portion 15 cooperates with the connecting portion 34 to clamp the liner 10 between the abutting portion 33 and the clamping portion 34 .

[0073] Furthermore, the clamping portion 341 is configured to have a clamping arm 342 extending along the air duct width direction Y, and the liner 10 is clamped between the flange portion 331 and the clamping arm 342. The clamping arm 342 extending along the air duct width direction Y is conducive to applying a uniform clamping force to the liner 10.

[0074] Combined with Figure 3 It can be seen that the flange portion 331 includes an arc surface 332 extending along the length direction X of the air duct and matching the outer surface shape of the inner liner 10. The arc surface 332 matches the intersection of two mutually perpendicular wall surfaces of the inner liner 10, which is beneficial to the fitting and positioning of the flange portion 331 and the inner liner 10.

[0075] The tongue 15 is formed on a part of the peripheral wall of the hole 13, so that a notch 14 is formed on the inner side of the hole 13 for the clamping portion 341 to be inserted. This facilitates the installation of the air duct 30. In particular, when the end surface of the main body 31 is configured as a rectangle, the hole 13 on the liner 10 that communicates with the air duct is configured as a rectangle. In this way, the tongue 15 can be located on the two opposite short sides of the rectangular hole 13 to cooperate with the clamping portion 341.

[0076] Furthermore, along the depth direction D of the refrigeration appliance, the notch 14 is located in front of the tongue 15 , so as to facilitate the rapid assembly and positioning of the air duct 30 and the inner container 10 .

[0077] Accordingly, the flange portion 331 extending from the main body portion 31 can be formed into a rectangular shape, and the arc surface 332 is located on one side of the rectangular flange portion 331, especially on the long side of the rectangle. Thus, the air duct 30 can be inserted from the front to the back along the depth direction D of the refrigeration appliance 100, the clamping portion 341 is inserted from the notch 13, and the tongue portion 15 is inserted between the clamping portion 341 and the flange portion 331 and slides to the intersection of the arc surface 332 and the two mutually perpendicular walls of the inner liner 10 to fit.

[0078] To facilitate the insertion of the tongue 15 between the clamping arm 342 and the flange 331 , an end of the clamping arm 342 away from the arc surface 332 and the flange 331 form an opening 343 that gradually increases along the insertion direction of the air duct 30 .

[0079] The mounting portion 32 includes a cable management portion 35 extending from the mounting portion in a direction away from the main body portion 31, and the cable management portion 35 is used to limit or wind the cable 43 of the drive unit 42. The cable management portion 35 formed from the mounting portion 32 is conducive to arranging and disassembling the cable 43 of the drive unit 42.

[0080] In one embodiment, the cable management portion 35 is constructed on the abutment portion 33, which is beneficial to improving the convenience of cable arrangement and disassembly.

[0081] The cable management portion 35 may be configured in a “π” shape, and its height is adapted to the width of the cable 43 , which is beneficial for the cable management portion 35 to be adapted to cables 43 of different lengths.

[0082] The cable management portion 35 may be configured as follows: The shape of the cable 43 is suitable for arranging a single row or multiple rows of cables 43. It is conducive to the adaptation of the cable management part to cables 43 of different widths.

[0083] like Figure 7 In one embodiment shown, the cable management portion 35 is constructed on the connecting portion 34. This is beneficial for the air duct to be installed vertically on the inner tank along its length direction, so that it can be installed by snapping and is also beneficial for limiting or fixing the cable of the drive unit located on the upper side of the length direction in the air duct.

[0084] The cable management portion 35 is preferably disposed at a position of the abutment portion 33 close to the driving unit 42, which is beneficial for arranging and fixing the cables.

[0085] When the cable management portion 35 is constructed on the abutment portion 33 , the cable management portion 35 and the connection portion 34 are arranged front and back in the width direction Y of the air duct 30 , which is beneficial to prevent the cable management portion 35 from interfering with the connection portion 34 .

[0086] When the cable management portion 35 is constructed on the connecting portion 34 , the cable management portion 35 is constructed as a cantilever overlapping the clamping arm 342 of the connecting portion 34 , and is used to clamp the cable 43 .

[0087] When the cable management portion 35 is constructed on the connecting portion 34, the cable management portion 35 is disposed near the opening 343 of the connecting portion 34, which is beneficial for arranging and fixing the cables.

[0088] When the wire organizing portion 35 is constructed on the connecting portion 34 , the direction of the wire clamping opening 351 thereof is consistent with the installation and insertion direction of the air duct 30 .

[0089] Furthermore, a evacuation portion 51 is provided at the connection end between the internal air duct 50 and the air duct 30 to evade the wire management portion 35 .

[0090] Fig. 9 This is a three-dimensional diagram of the air duct with the damper assembly removed. Fig. 9 As shown, a groove 318 is provided at a position on the step portion 313 corresponding to the cable management portion 35, and the groove 318 is used to accommodate part of the cable 43 or foam, so as to reduce the influence of the cable arrangement on the sealing of the air duct.
