[0032] The refrigerator is generally provided with freezing and refrigerating chambers, and part of the refrigerator is provided with a pre-buried air duct structure between the two chambers to realize the circulation of cold air between the freezing and refrigerating chambers. Based on this, an opening is arranged on the chamber, and at the present stage, the air duct structure is not closely contacted between the air port and the chamber, and the chamber wall is relatively soft, which is easy to produce gap. When the refrigerator is filled with foaming material, the foaming material is easy to overflow from the air port, which affects the performance of the refrigerator.

[0033] In view of this, the utility model provides an air duct component, please refer to Figures 1 to 4 For the embodiments of the air duct component provided in the present application, the air duct component will be described in detail below in combination with specific drawings.

[0034] Please refer to Figures 1 to 4 The air duct component 100 is used to connect two chambers 200 of the refrigerator 1000, wherein the air duct component 100 comprises a main body 1, the main body 1 internally defines an air duct 11, and the main body 1 is provided with an air inlet and an air outlet, the air inlet and the air outlet are communicated through the air duct 11, and the main body 1 is integrally formed with a sealing protruding rib 12, the sealing protruding rib 12 is annularly arranged on the outer edge of the air inlet and / or the air outlet, and the sealing protruding rib 12 is used to abut against the outer wall of the chamber 200.

[0035] In the technical scheme of the present application, an air duct 11 structure is mainly provided for connecting two chambers 200 of a refrigerator 1000 and ensuring the sealing of the joint between the air duct 11 structure and the chamber 200, so as to improve or even avoid the overflow of foaming material from the joint during foaming, thereby avoiding the influence on the performance of the refrigerator 1000.

[0036] It can be understood that the current solution to the problem of bubble leakage is mostly to paste a sponge around the air port. Installing the air duct member 100 requires pasting two sponges to prevent bubble leakage. Whether the sponge is pasted on the outer wall of the chamber 200 or on the air duct member 100, two sponge parts need to be added, the material cost increases, and additional pasting operation procedures are required, which increases the time cost and labor cost if manual operation is required. When the order demand increases, the material cost, time cost, labor cost, etc. in the overall production process will greatly increase. The sealing protrusions 12 are directly formed on the air duct member 100 in the present application, and the sealing protrusions 12 abut against the outer wall of the chamber 200 to seal the joint between the air duct member 100 and the chamber 200, thereby achieving the anti-bubble leakage function. Such a setting only needs to adjust the mold of the air duct member 100, without the need for additional parts and additional operation procedures. After the air duct member 100 is installed corresponding to the chamber 200, the anti-leakage function is met, the cost is low, and the practicality is strong.

[0037] It should be noted that the air duct member 100 is fixed to the chamber 200, so that the way the sealing protrusions 12 abut against the outer wall of the chamber 200 is not specifically limited. The sealing protrusions 12 can be pressed by the foaming material without displacement when the refrigerator 1000 is foaming, and the sealing protrusions 12 can be tightly abutted against the chamber 200. In the present embodiment, the air duct member 100 is embedded between two chambers 200 spaced apart in the first direction, and the air inlet and the air outlet are located on both sides of the main body 1 in the first direction. In this way, the air duct member 100 can be fixed between the two chambers 200 without the need for additional fixing structures. During the foaming process, the foaming material presses the two chambers 200, so that when the two chambers 200 approach each other, the air duct member 100 can be further tightly abutted, ensuring the stability of the air duct member 100. The air inlet and the air outlet on the air duct member 100 are also located on both sides of the main body 1 in the first direction. When the two chambers 200 approach each other, the sealing protrusions 12 can tightly abut against the outer wall of the chamber 200, thereby ensuring the sealing property and preventing the foaming material from overflowing, and meeting the functional requirements.

[0038] Further, the part of the main body 1 embedded between the two chambers 200 needs to avoid the positioning ribs on the outer wall of the chamber 200, so in this embodiment, positioning grooves 14 are also provided on both sides of the main body 1 in the first direction, which are used to cooperate with the positioning ribs on the outer wall of the chamber 200, that is, when the main body 1 is embedded between the two chambers 200, the positioning ribs on the chamber 200 extend into the positioning grooves 14 on the main body 1, which on the one hand positions the main body 1 to ensure that the air inlet and the air outlet on the main body 1 are aligned with the openings on the chamber 200, and on the other hand limits the main body 1 in the third direction to achieve positioning and fixation of the main body 1, and on the other hand, the drawer groove recessed on the inner side of the chamber 200 is formed by bending, and the positioning rib protruding from the outer wall is formed at the same time, which is used to limit the main body 1, and the structure is ingenious.

[0039] Further, the sealing protruding rib 12 is elastically arranged. The elastically arranged sealing protruding rib 12 elastically deforms when pressed, which on the one hand avoids damage to the sealing protruding rib 12 when pressed, and on the other hand the deformed sealing protruding rib 12 can better seal the gap between the chamber 200 and the air duct member 100, ensuring sealing performance and thus improving the problem of foaming overflow.

[0040] In addition, in order to ensure the sealing performance of the sealing protruding rib 12, a plurality of sealing protruding ribs 12 are provided on the outer edge of the air inlet and / or the air outlet in this embodiment, and the plurality of sealing protruding ribs 12 are sequentially sleeved. In this way, multiple sealing rings are formed, and multiple sealing areas are formed by sequentially sleeving, so as to improve the sealing performance of the sealing protruding rib 12 and ensure the sealing performance between the air duct member 100 and the chamber 200, thereby playing a multi-layer protection role.

[0041] In addition, the air duct member 100 is an integral molding structure formed by a mold, and generally a demolding ejector pin needs to be provided when the mold is demolded. In this embodiment, the ejector pin is provided corresponding to the position of the sealing protruding rib 12, so in this embodiment, an avoiding part 13 is provided on the main body 1 at the outer edge of the air inlet and / or the air outlet, and the sealing protruding rib 12 is bent to avoid the avoiding part 13 at the avoiding part 13. The avoiding section 121 is used to avoid the avoiding part 13, so that the above demolding ejector pin abuts against the avoiding part 13 when demolding, and avoids the structure of the sealing protruding rib 12, so as to avoid the problem that when the air duct member 100 is demolded, the ejector pin abuts against the sealing protruding rib 12, causing damage to the sealing protruding rib 12 and affecting the sealing performance.

[0042] Further, the sealing protrusions 12 are arranged at the outer edges of the air inlet and / or the air outlet, and the sealing protrusions 12 are arranged in sequence, the avoiding portions 13 are arranged between two adjacent sealing protrusions 12, and the avoiding portions 121 of the two adjacent sealing protrusions 12 are arranged in directions away from each other. As described above, the sealing protrusions 12 are arranged in sequence, and the avoiding portions 13 are arranged between two adjacent sealing protrusions 12, and the avoiding portions 121 of the two adjacent sealing protrusions 12 are arranged in directions away from each other, so as to avoid the problem that the two avoiding portions 121 are close to each other and are not easy to be formed.

[0043] Specifically, the height of the sealing protrusion 12 affects the sealing performance, and therefore, in the embodiment, the height of the sealing protrusion 12 is limited to be between 1.5 mm and 2.5 mm, so as to avoid the problem that the sealing protrusion 12 is less than 1.5 mm and cannot abut against the outer wall of the chamber 200, and further, the problem that the sealing protrusion 12 is greater than 2.5 mm and is easy to be broken laterally when pressed, so as to guarantee the sealing performance and stability of the sealing protrusion 12.

[0044] In addition, the body 1 further protrudes in the second direction and is provided with a supporting protrusion 15, so as to abut against and support the back plate of the refrigerator 1000, the body 1 is arranged between the two chambers 200, so that the two chambers 200 limit the movement of the body 1 in the first direction, and the positioning groove 14 on the body 1 cooperates with the positioning rib on the outer wall of the chamber 200, so as to limit the movement of the body 1 in the third direction, as described above. In the embodiment, the body 1 further protrudes in the second direction and is provided with the supporting protrusion 15, so as to abut against and support the back plate of the refrigerator 1000, so that the back plate and the chamber 200 clamp the body 1 in the second direction, so as to limit the movement of the body 1 in the second direction, so as to satisfy the positioning and fixing of the air duct component 100 in space, and guarantee the structural stability. In addition, the supporting protrusion 15 supports the back plate, so as to avoid the collapse of the back plate towards the chamber 200, so that the back plate is spaced from the chamber 200, so as to facilitate the filling of the foaming material, guarantee the uniformity of the filling, and guarantee the heat preservation performance of the foaming material on the chamber 200 and the appearance of the back plate.

[0045] Please refer to Figure 5The refrigerator 1000 comprises two cavities 200 and an air duct component 100, and the two cavities 200 are each provided with an opening; the air inlet and the air outlet of the air duct component 100 are respectively arranged corresponding to the opening of one cavity 200, and the specific structure of the air duct component 100 is referred to the above embodiments, and since the refrigerator 1000 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0046] Specifically, in order to guarantee the sealing performance of the sealing protrusion 12, the compression amount of the sealing protrusion 12 needs to be limited in addition to limiting the height of the sealing protrusion 12, that is, limiting the interference amount of the sealing protrusion 12 after the air duct component 100 is installed to the cavity 200, so in the embodiment, the relationship between the distance a between the air duct component 100 and the cavity 200 and the height h of the sealing protrusion 12 is 0.5mm≤h-a≤1mm, so as to limit the compression amount of the sealing protrusion 12 to 0.5mm to 1mm after the air duct component 100 is installed to the cavity 200, so as to guarantee that the sealing protrusion 12 abuts against the outer wall of the cavity 200, thereby guaranteeing the sealing performance.

[0047] In addition, the two cavities 200 are arranged at intervals in the first direction, and each cavity 200 is provided with two openings in the second direction, and the air duct component 100 is correspondingly provided with two in the second direction, and two air duct components 100 are respectively connected to two cavities 200 through a group of two openings, so as to form an air supply duct and an air return duct. In this way, the cold air generated after the evaporator cools down in the cavity 200 as a freezer room can be transported to the cavity 200 as a refrigerator room through the air supply duct to cool the refrigerator room, and the cold air blown into the refrigerator room is heated in the refrigerator room and then returned to the freezer room through the air return duct to be cooled by the evaporator, thereby realizing the circulation of the cold air between the freezer room and the refrigerator room, and meeting the freezing and refrigerating functions of the refrigerator 1000.

[0048] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by referring to the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
