[0032] The present invention will be described in detail below with reference to the embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any changes in structure, method, or function made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present invention.

[0033] Spatial relative position terms such as "upper", "lower", "left", "right", "front", "rear", etc. used herein are for the purpose of facilitating the description of the relationship between one feature and another as shown in the drawings. It can be understood that depending on the placement position of the product, the spatial relative position terms may be intended to include different orientations other than those shown in the drawings, and should not be construed as a limitation on the claims. In addition, the descriptive term "horizontal" used herein is not exactly the same as perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0034] As Figure 1-2 shown, the first embodiment of the present invention provides a refrigeration device 100, including a box body 30, a first inner liner 10 formed with a first compartment 11 inside the box body 30, a second inner liner 20 formed with a second compartment 21, an air duct assembly 40, and an evaporator 50 disposed in the first compartment 11. The evaporator 50 is used to refrigerate the first compartment 11, and the air duct assembly 40 is used to connect the first compartment 11 and the second compartment 21, so that the cold air in the first compartment 11 can flow through the air duct assembly 40 to the second compartment 21 to refrigerate the second compartment 21. A foaming space for filling foaming material is formed at intervals between the box body 30, the first inner liner 10, and the second inner liner 20, and the foaming material has an effect of heat insulation.

[0035] It should be noted that the up and down directions herein are the height direction of the refrigeration device 100, the horizontal direction is the width direction of the refrigeration device 100, that is, the left and right directions when the refrigeration device 100 is in the Figure 1 shown state, and the front and rear directions are the thickness direction of the refrigeration device 100, that is, when the refrigeration device 100 is inFigure 3 The left - right direction in the state shown.

[0036] In this embodiment, the first compartment 11 is a freezing compartment, and the second compartment 21 is a refrigerating compartment. In other embodiments, the second compartment 21 can also be a variable - temperature compartment or a freezing compartment.

[0037] Continuing to combine Figure 3-6 As shown, the air duct assembly 40 is located at the rear side of the second inner liner 20 and includes a front cover plate 41, a rear cover plate 42, and a air - supply duct 43 formed by enclosing the front cover plate 41 and the rear cover plate 42, which connects the second compartment 21 and the first compartment 11. The cold air in the first compartment 11 can flow into the second compartment 21 through the air - supply duct 43. In this embodiment, the air duct assembly 40 is hidden at the rear side of the second inner liner 20, that is, in the foaming space between the box body 30 and the inner liner. Compared with the prior art, there is no need to set an air duct structure in the second compartment 21, saving the space of the second compartment 21, and there is no problem of air leakage at the splicing joint caused by the splicing of the air duct assembly in the prior art.

[0038] The air - supply duct 43 includes an air inlet 432 communicating with the first compartment 11. The refrigeration device 100 further includes a damper assembly 70 loaded into the air - supply duct 43 from the air inlet 432. The damper assembly 70 is used to control the on - off between the first compartment 11 and the air - supply duct 43. When the damper assembly 70 is opened, the cold air in the first compartment 11 can enter the air - supply duct 43; when the damper assembly 70 is closed, the cold air in the first compartment 11 cannot enter the air - supply duct 43. By controlling the on - off between the first compartment 11 and the air - supply duct 43, the temperature of the second compartment 21 can be further controlled. At least part of the damper assembly 70 is located in the first compartment 11, and the damper assembly 70 is arranged to be loaded into or detached from the air - supply duct 43 from the first compartment 11. When installing and replacing the damper assembly 70, the operator can operate in the first compartment 11, which is convenient for operation.

[0039] Specifically, the air duct assembly 40 is located outside the first compartment 11 and is attached to the side wall of the first inner liner 10. An opening 12 corresponding to the air inlet 432 is provided on the first inner liner 10. The damper assembly 70 passes through the opening 12, that is, part of the damper assembly 70 is located in the first compartment 11, and the other part is located in the air - supply duct 43.

[0040] Further, a wrap - around edge 71 is provided around the damper assembly 70. The wrap - around edge 71 is located in the first compartment 11 and is attached to the inner surface of the first inner liner 10. The wrap - around edge 71 can prevent the foaming material from overflowing into the first compartment 11 from the opening 12.

[0041] In other embodiments, the air duct assembly 40 can also partially extend into the first compartment 11. At this time, the air duct assembly 40 can be entirely located in the first compartment 11.

[0042] As Figure 1 shown, in this embodiment, the refrigeration device 100 further includes a blower 80 disposed in the first compartment 11. The blower 80 is configured to promote the cold air in the first compartment 11 to flow into the air supply duct 43. The damper assembly 70 and the blower 80 are arranged offset in the lateral direction to prevent the humid air generated in the first compartment 11 from rising and freezing at the damper assembly 70 during the defrosting process, which may cause the damper assembly 70 to malfunction.

[0043] Continuing with reference to Figure 5 and 7 -8, a receiving cavity 22 is recessed from the rear to the front on the rear side of the second inner container 20. The width of the receiving cavity 22 is smaller than the width of the second inner container 20. A ventilation opening 23 is formed in the side wall of the second inner container 20 adjacent to the receiving cavity 22, and the ventilation opening 23 communicates with the second compartment 21. At least part of the duct assembly 40 is disposed in the receiving cavity 22. The air supply duct 43 communicates with the first compartment 11 and includes an air outlet 431 corresponding to the ventilation opening 23 to communicate with the second compartment 21. With the above design, after the cold air in the first compartment 11 flows into the air supply duct 43, it flows out of the air supply duct 43 from the air outlet 431 and then flows into the second compartment 21 from the ventilation opening 23.

[0044] The side wall of the second inner container 20 adjacent to the receiving cavity 22 should be understood as the side wall of the second inner container 20 that surrounds and forms the receiving cavity 22. A plurality of ventilation openings 23 should be provided and arranged in the height and width directions of the second inner container 20 so that the cold air in the air supply duct 43 can flow out evenly to various parts of the second compartment 21.

[0045] Continuing with reference to Figure 9 shown, the front cover plate 41 is located in front of the rear cover plate 42, that is, the front cover plate 41 is closer to the second inner container 20 than the rear cover plate 42. Specifically, the front cover plate 41 includes a front cover plate body 411 and a first rib 412 protruding from the front cover plate body 411 toward the rear cover plate 42. The rear cover plate 42 includes a rear cover plate body 421 and a second rib 422 protruding from the rear cover plate body 421 toward the front cover plate 41. The second rib 422 is located within the space surrounded by the first rib 412 and is in contact with the first rib 412. The front cover plate 41 and the rear cover plate 42 are spliced to form the duct assembly 40 through the first rib 412 and the second rib 422. It can be conceived that the air supply duct 43 is surrounded by the front cover plate body 411, the rear cover plate body 421, and the first rib 412 and the second rib 422 located therebetween. Corresponding notches are formed on the first rib 412 and the second rib 422 to form at least part of the air outlet 431 of the air supply duct 43.

[0046] The heights of the first rib 412 and the second rib 422 are equal. In this way, when the front cover plate 41 and the rear cover plate 42 are joined together, the first rib 412 contacts the rear cover plate body 421, and the second rib 422 contacts the front cover plate body 411, so that the front cover plate 41 and the rear cover plate 42 are closely joined together. After the front cover plate 41 and the rear cover plate 42 are joined, a tape can be pasted at the joint to prevent the foaming material from entering the air supply duct 43. The front cover plate 41 and the rear cover plate 42 can be made of foam material and have a good heat insulation effect.

[0047] It can be conceived that in other embodiments, it can also be that the first rib 412 is located in the space surrounded by the second rib 422 and fits with the second rib 422.

[0048] Continue to combine Figure 3 、 8 As shown in FIGS. 10-12, the ventilation openings 23 include at least two first ventilation openings 231 respectively located on both sides of the receiving cavity 22 in the lateral direction. The air supply duct 43 includes at least two first air outlet openings 4311 corresponding to the at least two first ventilation openings 231 to communicate with the second compartment 21. The number of the first ventilation openings 231 is the same as the number of the first air outlet openings 4311. The air supply duct 43 communicates with the second compartment 21 through the at least two first ventilation openings 231, and the cold air therein can flow into the second compartment 21 in the lateral direction. In this embodiment, there are two first ventilation openings 231. In other embodiments, the number of the first ventilation openings 231 can also be set to four, six or even more.

[0049] In this embodiment, both the upper and lower sides of the first ventilation opening 231 exceed the corresponding first air outlet opening 4311. In this way, there is a margin of dislocation in the vertical direction between the first air outlet opening 4311 and the corresponding first ventilation opening 231, avoiding the situation that the first air outlet opening 4311 and the first ventilation opening 231 cannot be aligned due to dimensional differences during the installation of the air duct assembly 40, and the air duct assembly 40 cannot evenly supply air to each storage space in the second compartment 21. Specifically, the dimensions by which the upper and lower sides of the first ventilation opening 231 exceed the corresponding first air outlet opening 4311 are greater than 2 mm.

[0050] The second inner container 20 and the first inner container 10 are arranged in the vertical direction, where the position of the second inner container 20 is above and the position of the first inner container 10 is below. The accommodation cavity 22 includes a first recessed portion 221 and a second recessed portion 222 located above the first recessed portion 221. The recessed depth of the first recessed portion 221 is greater than that of the second recessed portion 222. The second inner container 20 includes a first side wall 24 located above the first recessed portion 221. Part of the front cover plate 41 is located in the first recessed portion 221. The upper side of the front cover plate 41 is in contact with the first side wall 24 in the vertical direction. The lower side of the front cover plate 41 and / or the rear cover plate 42 is in contact with the side wall of the first inner container 10 in the vertical direction. In this way, the position of the air duct assembly 40 in the vertical direction is defined.

[0051] Furthermore, the second inner container 20 includes an upper side wall 25 on its upper side. The second recessed portion 222 penetrates to the upper end of the second inner container 20. The rear cover plate 42 includes a protruding portion 423 that protrudes upward from the front cover plate 41 and fits against the upper side wall 25. The protruding portion 423 extends upward and forward, generally in a J shape or an L shape. An intermediate cavity 26 is formed by enclosing the side wall of the second inner container 20 near the second recessed portion 222 and the air duct assembly 40. A second ventilation opening 232 is formed in the side wall of the second inner container 20 near the second recessed portion 222. The second ventilation opening 232 communicates with the second compartment 21. The air supply duct 43 includes a second air outlet 4312 that communicates with the intermediate cavity 26. The cold air in the air supply duct 43 can flow into the intermediate cavity 26 through the second air outlet 4312, and then flow from the intermediate cavity 26 into the second compartment 21 through the second ventilation opening 232. The protruding portion 423 can be specifically bonded to the upper side wall 25.

[0052] The side wall of the second inner container 20 near the second recessed portion 222 should be understood as the side wall of the second inner container 20 that encloses the second recessed portion 222. In this embodiment, the second inner container 20 includes a second side wall 27 located in front of the second recessed portion 222 and two third side walls 28 located on both sides of the second recessed portion 222 in the transverse direction. Second ventilation openings 232 are formed on the second side wall 27 and the two third side walls 28. Two second ventilation openings 232 are formed on the second side wall 27, and one second ventilation opening 232 is formed on each of the two third side walls 28. Two second air outlets 4312 are provided, and the two second air outlets 4312 are respectively close to the two second ventilation openings 232.

[0053] In this embodiment, the accommodation cavity 22 is flat, that is, the thickness of the accommodation cavity 22 in the front-rear direction is much smaller than the width of the accommodation cavity 22 extending in the transverse direction or the length extending in the vertical direction, so that the accommodation cavity 22 occupies less space in the front-rear direction of the refrigerated compartment. The front cover plate 41 is bonded to the side wall of the second inner container 20 located on the front side of the accommodation cavity 22, so that the air duct assembly 40 is installed on the second inner container 20.

[0054] As Figure 13-16 shown, a second embodiment of the present invention provides another refrigeration device 100. Different from the first embodiment, in this embodiment, a gap 60 for filling foam material is formed at intervals in the front-rear direction between the air duct assembly 40 and the second inner container 20. The gap 60 communicates with the foam space formed by the intervals among the box body 30, the first inner container 10 and the second inner container 20. In this way, the foam material can flow into the gap 60, and the foam material located in the gap 60 can prevent the temperatures in the second chamber 21 and the air supply duct 43 from interfering with each other. At this time, the air duct assembly 40 can be made of plastic material.

[0055] Specifically, the air duct assembly 40 includes two first support parts 44 extending forward from the front cover plate 41, and two second support parts 45 respectively extending in the transverse direction from the ends of the two first support parts 44 away from the front cover plate 41. The two first support parts 44 are respectively located on both sides of the transverse direction, and the two second support parts 45 respectively extend from the ends of the two first support parts 44 away from the front cover plate 41 in a direction close to each other. The second support part 45 is bonded to the side wall of the second inner container 20 on the front side of the receiving cavity 22, so that the air duct assembly 40 is installed on the second inner container 20. The first support part 44 and the second support part 45 make a space between the front cover plate 41 and the second inner container 20 to form the above-mentioned gap 60.

[0056] The air supply duct 43 includes an air duct main path 433 extending in the up-down direction and a plurality of air duct branch paths 434 respectively extending from the air duct main path 433 to both sides in the transverse direction. At this time, the first air outlet 4311 of the air supply duct 43 is located at the end of the air duct branch path 434 away from the air duct main path 433.

[0057] It should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0058] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
