Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, and in particular to a refrigerator shell and an air-cooled vehicle refrigerator. Background Technology

[0002] As people's living standards improve, users have higher and higher requirements for refrigerators. However, refrigerators on the market currently produce a lot of frost during use, which requires users to remove it manually, seriously affecting normal use. Therefore, frost-free refrigerators have emerged.

[0003] In order to ensure assembly, air-cooled refrigerators usually leave an installation gap between the partition between the cooling chamber and the heat exchange chamber and the shell. Since it is difficult to seal the partition, air in the cooling chamber can easily leak out from the installation gap, resulting in a lower cooling rate of the cooling chamber. Utility Model Content

[0004] The main purpose of this invention is to propose a refrigerator shell and an air-cooled vehicle refrigerator, which aims to improve the sealing performance of the heat exchange chamber and the refrigeration chamber.

[0005] To achieve the above objectives, the refrigerator shell proposed in this utility model includes:

[0006] The shell body has a receiving cavity inside;

[0007] A partition, disposed within the receiving cavity, divides the receiving cavity into a refrigeration cavity and a heat exchange cavity. The refrigeration cavity is used for storage, and the heat exchange cavity is used for the installation of heat exchange equipment. The partition is provided with air vents.

[0008] An elastic sealing ring is disposed between the periphery of the partition and the shell body.

[0009] In one embodiment, the periphery of the partition is provided with a mounting flange, and the elastic sealing ring is disposed between the mounting flange and the shell body.

[0010] In one embodiment, the elastic sealing ring includes a sealing body and two sealing flanges respectively disposed on both sides of the sealing body. The sealing body is in contact with the outer peripheral surface of the mounting flange, one of the sealing flanges is in contact with the side of the partition facing the cooling cavity, and the other sealing flange is in contact with the end face of the mounting flange.

[0011] In one embodiment, the elastic sealing ring is engaged with the partition plate.

[0012] In one embodiment, the elastic sealing ring is provided with a snap-fit ​​protrusion, and the mounting flange is provided with a snap-fit ​​hole, wherein the snap-fit ​​protrusion is snapped into the snap-fit ​​hole.

[0013] In one embodiment, the resilient sealing ring has a plurality of sealing lips for abutting against the housing body.

[0014] In one embodiment, the elastic sealing ring is made of silicone.

[0015] In one embodiment, the heat exchange chamber wall is provided with a clearance recess for avoiding the installation of the compressor, and the clearance recess is provided with a sealing step corresponding to the periphery of the partition, the sealing step being used to abut against the periphery of the partition.

[0016] In one embodiment, the partition includes an air inlet section and an air outlet section connected to each other. The air inlet section is disposed corresponding to the relief recess and arches toward the cooling cavity. The air outlet includes an air inlet disposed in the air inlet section and an air outlet disposed in the air outlet section.

[0017] In one embodiment, the partition is snapped into the shell body; and / or

[0018] The partition and the shell body are connected by screws.

[0019] This utility model also proposes an air-cooled vehicle refrigerator, including the refrigerator shell described above.

[0020] The technical solution of this utility model divides the receiving cavity into a refrigeration cavity and a heat exchange cavity using a partition. An elastic sealing ring is installed between the periphery of the partition and the shell, thereby improving the sealing effect between the heat exchange cavity and the refrigeration cavity. This reduces the probability of air from the refrigeration cavity entering the heat exchange cavity through the installation gap, thus increasing the cooling rate of the refrigeration cavity. Furthermore, the elastic sealing ring has a certain degree of elasticity, allowing the partition and the shell to press the elastic sealing ring closer together when the partition is installed onto the shell body. This enables the elastic sealing ring to better seal the installation gap between the partition and the shell body, further improving the sealing performance between the heat exchange cavity and the refrigeration cavity.

[0032] As people's living standards improve, users have higher and higher requirements for refrigerators. However, refrigerators on the market currently produce a lot of frost during use, which requires users to remove it manually, seriously affecting normal use. Therefore, frost-free refrigerators have emerged.

[0033] In order to ensure assembly, air-cooled refrigerators usually leave an installation gap between the partition between the cooling chamber and the heat exchange chamber and the shell. Since it is difficult to seal the partition, air in the cooling chamber can easily leak out from the installation gap, resulting in a lower cooling rate of the cooling chamber.

[0034] To solve the above problems, this utility model proposes a refrigerator shell 10.

[0035] Please see Figures 1 to 4 In one embodiment of this utility model, the refrigerator shell 10 includes a shell body 100, a partition 200, and an elastic sealing ring 300. The shell body 100 has a receiving cavity 110. The partition 200 is disposed in the receiving cavity 110 to divide the receiving cavity 110 into a cooling cavity 111 and a heat exchange cavity 112. The cooling cavity 111 is used for storing items, and the heat exchange cavity 112 is used for installing heat exchange equipment. The partition 200 has an air vent 210. The elastic sealing ring 300 is disposed between the periphery of the partition 200 and the shell body 100.

[0036] The technical solution of this utility model uses a partition 200 to divide the receiving cavity 110 into a cooling cavity 111 and a heat exchange cavity 112. An elastic sealing ring 300 is provided between the periphery of the partition 200 and the shell, thereby improving the sealing effect between the heat exchange cavity 112 and the cooling cavity 111. This reduces the probability of air in the cooling cavity 111 entering the heat exchange cavity 112 through the installation gap, thus increasing the cooling rate of the cooling cavity 111. Furthermore, the elastic sealing ring 300 has a certain degree of elasticity. When the partition 200 is installed onto the shell body 100, the partition 200 and the shell body 100 can press the elastic sealing ring 300 towards each other, allowing the elastic sealing ring 300 to better seal the installation gap between the partition 200 and the shell body 100, further improving the sealing performance between the heat exchange cavity 112 and the cooling cavity 111.

[0037] Furthermore, this solution uses an elastic sealing ring 300 to seal the installation gap between the partition 200 and the shell body 100. Compared to using foam material to seal the installation gap between the partition 200 and the shell body 100, this solution can reduce odors within the receiving cavity 110. Moreover, sealing the installation gap with foam material requires a certain foaming time to achieve a better sealing effect, while this solution only requires pressing the elastic sealing ring 300 between the partition 200 and the shell body 100 to achieve a sealing effect. Therefore, this solution can also improve the production efficiency of the refrigerator shell 10.

[0038] Optionally, the partition 200 has a mounting flange 220 around its periphery, and the elastic sealing ring 300 is disposed between the mounting flange 220 and the shell body 100. It can be understood that the mounting flange 220 increases the contact area between the partition 200, the elastic sealing ring 300, and the shell body 100, thereby improving the sealing effect between the heat exchange chamber 112 and the cooling chamber 111. Of course, this solution is not limited to this. In other embodiments, the partition 200 may not have a mounting flange 220 around its periphery, and the periphery of the partition 200 may directly abut against the elastic sealing ring 300.

[0039] Furthermore, the elastic sealing ring 300 includes a sealing body 310 and two sealing flanges 320 respectively disposed on both sides of the sealing body 310. The sealing body 310 is fitted with the outer peripheral surface of the mounting flange 220, one sealing flange 320 is fitted with the side of the partition 200 facing the cooling cavity 111, and the other sealing flange 320 is fitted with the end face of the mounting flange 220. It can be understood that the elastic sealing ring 300 can be pre-fitted onto the mounting flange 220, that is, the elastic sealing ring 300 can be pre-installed on the partition 200, thereby facilitating the operation of setting the elastic sealing ring 300 between the partition 200 and the shell body 100, which is beneficial to the installation efficiency. Of course, this solution is not limited to this. In other embodiments, the elastic sealing ring 300 may also only include the sealing body 310, which is fitted with the outer peripheral surface of the mounting flange 220.

[0040] Two sealing flanges 320 are respectively provided on both sides of the sealing body 310. One of the sealing flanges 320 is attached to the side of the partition 200 facing the cooling cavity 111, and the other sealing flange 320 is attached to the end face of the mounting flange 220. Compared with the solution that only has a sealing body 310 attached to the outer peripheral surface of the mounting flange 220, the sealing flange 320 can cover the gap between the outer peripheral surface of the mounting flange 220 and the sealing body 310, thereby helping to further increase the sealing effect between the heat exchange cavity 112 and the cooling cavity 111.

[0041] Furthermore, the elastic sealing ring 300 also includes a covering flange, which is disposed on the sealing flange 320 that is in contact with the end face of the mounting flange 220 and is located on the side of the sealing flange 320 away from the sealing body 310. This forms a fitting groove between the covering flange, the sealing flange 320 and the sealing body 310, and the free end of the mounting flange 220 is placed in the fitting groove. This can further increase the stability of the elastic sealing ring 300 fitted on the mounting flange 220, thereby reducing the probability that the elastic sealing ring 300 will detach from the mounting flange 220 when the partition plate 200 is installed on the shell body 100 due to the lateral pushing force of the shell body 100.

[0042] Optionally, in one embodiment, the elastic sealing ring 300 is snapped onto the partition 200. This snap-fit ​​installation method is simple and improves the installation efficiency of the elastic sealing ring 300 and the partition 200. Furthermore, snapping the elastic sealing ring 300 onto the partition 200 reduces the likelihood of the elastic sealing ring 300 detaching from the mounting flange 220 due to the lateral pushing force of the shell body 100 when the partition 200 is installed onto the shell body 100. Moreover, the snap-fit ​​method allows for disassembly; after the elastic sealing ring 300 loses its elasticity through long-term use, it can be replaced, thus ensuring the sealing effect of the cooling cavity 111 and the heat exchange cavity 112, and guaranteeing the long-term cooling effect of the air-cooled refrigerator. Of course, this solution is not limited to this; in other embodiments, the elastic sealing ring 300 can also be bonded to the partition 200.

[0043] Furthermore, the elastic sealing ring 300 is provided with a snap-fit ​​protrusion, and the mounting flange 220 is provided with a snap-fit ​​hole. The snap-fit ​​protrusion snaps into the snap-fit ​​hole. This snap-fit ​​structure is simple in structure, easy to process, and simple in installation, which helps to improve the installation efficiency of the elastic sealing ring 300. Of course, this solution is not limited to this. In the second embodiment, the elastic sealing ring 300 can also be bonded to the partition plate 200. Of course, this solution is not limited to this. In the third embodiment, a snap-fit ​​protrusion can also be provided on the mounting flange 220, and a snap-fit ​​groove can be provided on the elastic sealing gasket, with the snap-fit ​​protrusion snapping into the snap-fit ​​groove.

[0044] Furthermore, in this embodiment, the elastic sealing ring 300 is provided with a plurality of sealing lips 330 for abutting against the shell body 100, which can better seal the installation gap between the partition 200 and the shell body 100, and further increase the sealing effect of the heat exchange chamber 112 and the cooling chamber 111.

[0045] Optionally, the elastic sealing ring 300 is made of silicone. This is because silicone can maintain stable physical properties under extreme temperature environments, without significant deformation or loss of sealing performance, which helps to improve the service life of the elastic sealing ring 300. More importantly, silicone has very good elasticity and resilience; after repeated compression and stretching, it can still return to its original shape. This excellent elastic recovery performance allows the silicone elastic sealing ring 300 to adapt to installation gaps of different shapes and sizes, providing a reliable sealing effect. Furthermore, silicone has a low odor, which helps to reduce odors from the refrigerator casing 10. Of course, this solution is not limited to this; in other embodiments, the elastic sealing ring 300 can also be made of fluororubber.

[0046] Optionally, the heat exchange chamber 112 has a recess 120 on its wall to allow for compressor installation. The recess 120 has a sealing step 121 corresponding to the periphery of the partition 200, which abuts against the periphery of the partition 200. It is understood that the recess 120 allows for a more compact overall refrigerator structure, reducing its size. Furthermore, the sealing step 121 corresponding to the periphery of the partition 200 increases the contact area between the recess 120 and the periphery of the partition 200, facilitating the sealing of the installation gap between the partition 200 and the recess 120, thereby improving the sealing effect of the heat exchange chamber 112 and the cooling chamber 111.

[0047] Optionally, the partition 200 includes an air inlet section 230 and an air outlet section 240 connected to each other. The air inlet section 230 is disposed corresponding to the relief recess 120 and arches towards the cooling cavity 111. The air passage 210 includes an air inlet 211 disposed in the air inlet section 230 and an air outlet 212 disposed in the air outlet section 240. It can be understood that an air passage is formed between the side wall of the relief recess 120 and the air inlet section 230, causing the air inlet section 230 to arch towards the cooling cavity 111. This ensures the ventilation area of ​​the air passage while making the structure of the refrigerator shell 10 more compact and improving the space utilization of the refrigerator shell 10. Of course, this solution is not limited to this. In other embodiments, the partition 200 may also be planar.

[0048] Furthermore, in other embodiments, an air inlet or an air outlet may be provided only on the partition 200.

[0049] Optionally, in one embodiment, the partition 200 is snap-fitted to the shell body 100; this is because snap-fitting typically does not require complex tools or skills, and the connection can be completed simply by aligning and inserting. Therefore, using snap-fitting improves the installation efficiency of the partition 200 and the shell body 100. When parts need to be replaced or repaired, snap-fitting allows for quick disassembly, reducing maintenance time and costs.

[0050] Optionally, in one embodiment, the partition 200 and the shell body 100 are connected by screws. Screw connections require only two parts: a screw and a nut, resulting in relatively low material costs compared to other connection methods. Furthermore, screw connections are easy to mass-produce and apply, further reducing the cost of the refrigerator shell 10. Moreover, the installation and disassembly process of screw connections is relatively simple, requiring no complex tools or equipment. This ease of disassembly makes maintenance and parts replacement simple and quick, saving significant manpower and time costs. The simplicity of screw connections also makes inspection and maintenance easier. Workers can easily disassemble and reinstall the partition 200 for regular inspections and necessary maintenance.

[0051] In this embodiment, the partition 200 is both snapped onto the shell body 100 and screwed onto the shell body 100, which helps to improve the installation stability of the partition 200.

[0052] This utility model also proposes an air-cooled vehicle refrigerator, which includes a refrigerator shell. The specific structure of the refrigerator shell is as described in the above embodiments. Since this air-cooled vehicle refrigerator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
