[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "set", "connect", "connect", "fixed" and other such terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part.

[0020] This utility model provides a refrigeration device 100. Figures 1 to 10 An embodiment of a refrigeration device 100 according to the present invention is shown.

[0021] In this embodiment, the refrigeration device 100 is preferably a vertical freezer. It should be noted that although the present invention is described using a vertical freezer as an example, the present invention is not limited to this, and may also be other devices capable of providing refrigeration functions.

[0022] like Figures 1 to 4 The refrigeration equipment 100 shown includes a housing 10; the housing 10 includes an inner liner 4 forming a storage compartment 3, a refrigeration system 5 for supplying cooling to the storage compartment 3, and a compartment partition 6 disposed between the inner liner 4 and the refrigeration system 5.

[0023] The partition 6 in the engine compartment facilitates the positioning and installation of the refrigeration system 5 and the inner liner 4, while also isolating the refrigeration system 5 from the inner liner 4, reducing the impact of noise and vibration generated by the refrigeration system 5 during operation on the items inside the storage compartment 3.

[0024] The inner liner 4 is provided with a return air inlet 42 and an air inlet 41; the nacelle partition 6 includes a return air interface 612 that matches the return air inlet 42 and is connected to the refrigeration system 5, and an air inlet interface 613 that matches the air inlet 41 and is connected to the refrigeration system 5.

[0025] By setting the return air interface 612 and the air inlet interface 613, after the refrigeration system 5 is connected to the engine compartment partition 6, the hot air in the storage room 3 can smoothly enter the refrigeration system 5 through the return air interface 612, while the cold air generated by the refrigeration system 5 can smoothly enter the storage room 3 through the air inlet interface 613.

[0026] The housing 10 also includes a first connector 7 for connecting the return air inlet 612 and the inner liner 4, and a second connector 8 for connecting the air inlet 613 and the inner liner 4. The first connector 7 and the second connector 8 not only provide good positioning for the installation position of the nacelle partition 6 and the refrigeration system 5, but also ensure that the return air inlet 612 and the air inlet 613 are directly aligned and connected with the return air inlet 42 and the air inlet 41, thus ensuring the assembly accuracy between the nacelle partition 6 and the inner liner 4, simplifying the installation process, and improving assembly efficiency. At the same time, it ensures the smooth transmission of cold air, reduces cold leakage, and improves refrigeration efficiency and effect.

[0027] The first connector 7 and the second connector 8 can respectively achieve a stable connection between the return air interface 612 and the air inlet interface 613 and the inner liner 4, further ensuring the connection stability and cooling effect between the refrigeration equipment 100 and the inner liner 4.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0029] Reference Figures 2 to 4 In this embodiment, the cabinet 10 includes a rectangular outer shell 101 with a retrieval window 2 on its front, facilitating the user to retrieve items from the storage compartment 3. An insulation layer 102, made of, for example, polyurethane foam, is formed between the inner liner 4 and the outer shell 101 to reduce heat transfer from the inside of the refrigeration equipment 100 to the outside, thus maintaining a stable temperature inside the storage compartment 3.

[0030] The refrigeration equipment 100 also includes a door 20 located on one side of the retrieval window 2. In this embodiment, the door 20 of the upright freezer can be, for example, a glass door panel with a certain thickness, which makes it easy for users to observe the items in the storage room 3 and also has a certain display effect.

[0031] The door 20 is large enough to block the access window 2 and extends vertically to one side of the access window 2 on the main body shell 101. Users can conveniently access items in the storage room 3 by opening and closing the door 20.

[0032] The refrigeration system 5 is located on the lower side of the cabinet 10. The refrigeration equipment 100 can continuously provide cooling capacity to the storage room 3 through the operation of the refrigeration system 5, maintain the low temperature state in the storage room 3, and meet the refrigeration or freezing needs of the items.

[0033] The refrigeration system 5 includes a base 51, a compressor, a condenser, an evaporator, and other common components mounted on the base 51 and connected by pipes. In this embodiment, the compressor, condenser, evaporator, etc., are integrated into the base 51. When a problem occurs and repair or replacement is needed, only the base 51 needs to be completely removed and replaced, without having to remove the entire refrigeration equipment 100 for repair.

[0034] The inner liner 4 is provided with an air inlet 41 and an air return 42 that connect the refrigeration system 5 and the storage compartment 3. The refrigeration system 5 includes an exhaust vent 56 corresponding to the air inlet 41 and an air intake vent 55 corresponding to the air return vent 42.

[0035] The refrigeration system 5 includes an insulation component 53 mounted on the base 51, an evaporator 52, and a cooling fan 54 housed inside the insulation component 53. The operation of the cooling fan 54 drives airflow, creating negative pressure. This draws hot air from the storage compartment 3 through the return air inlet 42 and into the evaporator 52 via the air intake 55 of the refrigeration system 5 for cooling. The evaporator 52 exchanges heat with the drawn-in hot air, converting it into cold air. The cold air is then transported by the cooling fan 54 from the air inlet 41 into the storage compartment 3, achieving circulating cooling of the air within the storage compartment 3.

[0036] To ensure accurate connection and communication between the air intake 55 and exhaust 56 of the refrigeration system 5 and the return air 42 and air inlet 41 of the inner liner 4, the housing 10 further includes a hopper partition 6 located between the inner liner 4 and the refrigeration system 5. The hopper partition 6 includes a return air interface 612 that matches the return air 42 and communicates with the refrigeration system 5, and an air inlet interface 613 that matches the air inlet 41 and communicates with the refrigeration system 5. The return air inlet 612 is connected to the inner liner 4 via the first connector 7, and the air inlet 613 is connected to the inner liner 4 via the second connector 8.

[0037] Specifically, refer to Figures 5 to 8 The first connector 7 includes a positioning frame 71 that fits into the return air vent 42 and abuts against the inner side of the return air interface 612, and a flange 72 that extends from the positioning frame 71 and abuts against the inner wall of the inner liner 4.

[0038] The positioning frame 71 is embedded in the return air vent 42 and abuts against the inner side of the return air interface 612, ensuring a tight connection between the return air interface 612 and the return air vent 42 without air leakage. The structure of the flange 72 not only enhances the stability of the connection, but also further enhances the sealing effect by fitting snugly against the inner wall of the inner liner 4.

[0039] One of the positioning frame 71 and the return air interface 612 is provided with at least one first latching part 74, and the other is provided with at least one first slot 73 that engages with the first latching part 74.

[0040] The first fastener 74 and the first slot 73 engage to achieve a secure connection between the first connector 7 and the return air interface 612, which facilitates installation and disassembly and improves assembly efficiency.

[0041] In this embodiment, the positioning frame 71 is provided with a plurality of first slots 73, which are evenly distributed around the periphery of the positioning frame 71. The return air interface 612 is provided with a plurality of first buckle parts 74 corresponding one-to-one with the plurality of first slots 73, so that the positioning frame 71 and the return air interface 612 can be connected at multiple points, thereby further enhancing the stability and sealing of the connection.

[0042] During assembly, firstly, the return air inlet 612 is placed against the edge of the return air vent 42. Then, the positioning frame 71 is pushed into the return air vent 42 to abut against the inner side of the return air inlet 612. Subsequently, the positioning frame 71 is rotated so that multiple first snap-fit ​​parts 74 are engaged in their corresponding first slots 73, achieving a stable connection. The flange 72 extends from the positioning frame 71 by bending. After the first snap-fit ​​parts 74 are engaged with the first slots 73, the flange 72 fits snugly against the inner wall of the inner liner 4, further enhancing the stability of the connection. Of course, the flange 72 can also be further fixed to the inner liner 4 by screws or snap-fits to ensure that there will be no loosening or air leakage during long-term use.

[0043] The second connector 8 includes a first connecting part 81 that abuts against the inner side of the air inlet 613 and a second connecting part 82 that abuts against the outer wall of the inner liner 4. One of the first connecting part 81 and the air inlet 613 is provided with at least one second latching part 84, and the other is provided with at least one second slot 85 that engages with the second latching part 84.

[0044] The second connector 8 and the air inlet 613 are securely connected by the snap-fit ​​engagement between the second snap-fit ​​part 84 and the second slot 85.

[0045] In this embodiment, the first connecting part 81 is provided with a plurality of second slots 85, which are evenly distributed around the periphery of the first connecting part 81. The air inlet 613 is provided with a plurality of second buckle parts 84 corresponding one-to-one with the plurality of second slots 85, so that the first connecting part 81 and the air inlet 613 can be connected at multiple points, thereby further enhancing the stability and sealing of the connection.

[0046] In order to optimize the transmission path of cold air and improve the cooling efficiency, the housing 10 is provided with a first air duct 11 connecting the air inlet 41 and the storage room 3, and the second connector 8 also includes an air guide groove 83 extending from the first connecting part 81 into the first air duct 11.

[0047] The air guide slot 83 can guide the cold air generated by the refrigeration system 5 smoothly into the first air duct 11, reducing the loss of cold energy during transmission and improving the refrigeration effect.

[0048] During assembly, firstly, the multiple second slots 85 of the second connector 8 are engaged with the corresponding second buckles 84 to achieve a secure connection between the second connector 8 and the air inlet 613. Then, the entire assembly of the second connector 8 and the nacelle partition 6 is pushed to the preset position of the inner liner 4, so that the second connector 82 fits against the outer wall of the inner liner 4. At this time, the air guide 83 extends into the first air duct 11 to ensure that the cold air can smoothly enter the first air duct 11 through the air guide 83.

[0049] To further enhance the connection stability between the second connector 8 and the inner liner 4, the second connector 82 may also be provided with a fastening structure, such as a screw hole or a snap-fit ​​structure, so as to fix the second connector 82 to the outer wall of the inner liner 4 by means of screws or snap-fits.

[0050] Combination Figures 9 to 11 To optimize the spatial layout of the refrigeration equipment 100, the inner liner 4 is provided with a step portion 43 adjacent to the refrigeration system 5, so that the box body 10 forms an accommodating space for installing the refrigeration system 5, which is arranged adjacent to the step portion 43 in front and behind, so as to meet the installation needs of the refrigeration system 5.

[0051] The stepped portion 43 includes a first wall 431 extending in the horizontal direction and a second wall 432 extending in the vertical direction. The first wall 431 and the second wall 432 are connected to each other to form a stable support structure.

[0052] In this embodiment, the first wall 431 is the upper side wall of the stepped portion 43, and the second wall 432 is the front side wall of the stepped portion 43. The first wall 431 and the second wall 432 are connected to each other so that the stepped portion 43 is formed as a protruding structure that extends in a stepped shape from the rear wall and bottom wall of the inner liner 4 into the storage compartment 3.

[0053] The return air vent 42 is located on the side of the first wall 431 near the second wall 432, and the air inlet 41 is located on the side of the first wall 431 near the rear wall of the inner liner 4. This ensures that the hot air in the storage compartment 3 can smoothly enter the refrigeration system 5 from the front side for cooling, while the cold air processed by the evaporator 52 can smoothly enter the storage compartment 3 from the top of the rear side of the refrigeration system 5, thus achieving a better air circulation path.

[0054] The second connecting part 82 includes a first connecting plate 821 that abuts against the first wall 431 and a second connecting plate 822 that abuts against the rear wall of the inner liner 4. That is, the first connecting plate 821 extends horizontally to fit vertically against the first wall 431, and the second connecting plate 822 extends vertically to fit front and back against the second wall 432. This makes good contact and sealing between the second connecting part 8 and the first wall 431 and the rear wall of the inner liner 4, effectively preventing cold air leakage and improving refrigeration efficiency.

[0055] The second connector 8 further includes a surrounding plate that vertically connects the first connecting plate 821 and the second connecting plate 822, to cooperate with the second connecting plate 822 to form the air guide groove 83. An air guide component 831 is provided within the air guide groove 83. The air guide component 831 is fixed to the second connecting plate 822 and extends into the first air duct 11, creating a retaining gap 832 between the air guide component 831 and the second connecting plate 822 for the rear wall of the inner liner 4 to engage. During the actual assembly of the second connector 8, the rear wall of the inner liner 4 can be used to engage the retaining gap 832 for convenient positioning and to determine whether the second connector 8 is properly assembled.

[0056] The naval partition 6 includes a top partition 61 that cooperates with the first wall 431 and a front partition 62 that cooperates with the second wall 432. The top partition 61 includes a main body 611 parallel to the first wall 431 and a return air inlet 612 and an air inlet 613 protruding from the main body 611 toward the inner liner 4. The internal dimensions of the return air inlet 612 match the return air inlet 42 to avoid partial obstruction of the return air inlet 42, which would increase return air resistance and reduce the return air volume.

[0057] In this embodiment, the front end of the first wall 431 is provided with a first opening 421 that penetrates its thickness, and the upper end of the second wall 432 is provided with a second opening 422 that penetrates its thickness. The first opening 421 and the second opening 422 are connected to form the return air vent 42.

[0058] In this way, the return airflow can flow into the refrigeration system 5 from the first opening 421 at the top of the step 43, or enter the refrigeration system 5 through the second opening 422 at the front of the step 43, thereby ensuring that the air circulation fully covers the storage area on the upper and front sides of the step 43, ensuring a more uniform temperature distribution in the storage room 3, and ensuring the refrigeration effect in all parts of the storage room 3.

[0059] The return air inlet 612 includes a first protrusion 6121 that abuts against the edge of the first opening 421 and a second protrusion 6122 that abuts against the edge of the second opening 422, so as to ensure that the return air inlet 612 can fit tightly against the edges of the first opening 421 and the second opening 422 of the stepped portion 43, avoid air leakage, and improve cooling efficiency.

[0060] The positioning frame 71 includes a first frame 712 and a second frame 711 disposed opposite to each other. The first frame 712 is engaged with the first protrusion 6121, and the second frame 711 is engaged with the second protrusion 6122 to ensure that the positioning frame 71 can be stably engaged with the return air interface 612.

[0061] The first connector 7 also includes a reinforcing plate 713 that connects the first frame 712 and the second frame 711 to enhance the connection strength between the first frame 712 and the second frame 711 and further improve the overall stability of the first connector 7.

[0062] The stepped portion 43 also includes a flanged wall 433 extending vertically rearward from the second wall 432 along the edge of the second opening 422, to increase the structural strength of the second opening 422, prevent deformation of the second opening 422 due to long-term use or external factors, and ensure the stability of the return air vent 42. Furthermore, the flanged wall 433 facilitates a sealed connection with the nacelle partition 6.

[0063] The return air inlet 612 includes an overlap portion 6123 corresponding to the flanged wall 433. The overlap portion 6123 protrudes downward from the front side of the main plate 611 to form a front air outlet gap that matches the second opening 422 between it and the main plate 611. The second protruding portion 6122 extends from the extension end of the overlap portion 6123 toward the first wall 431.

[0064] The refrigeration system 5 also includes a cover 58 covering the outside of the base 51 and the insulation component 53. The cover 58 can protect the base 51 and the insulation component 53, and can also reduce the transmission of noise and reduce the noise pollution generated during the operation of the refrigeration system 5.

[0065] The refrigeration system 5 also includes a sealing strip 57 arranged around the top edge of the cover 58. By setting the sealing strip 57 around the top edge of the cover 58, the refrigeration system 5 can be sealed and connected with the engine compartment partition 6, effectively preventing cold air from leaking from the gap between the cover 58 and the engine compartment partition 6, and improving the overall sealing performance of the refrigeration system 5.

[0066] The sealing strip 57 is made of elastic material, which has good elasticity and wear resistance, and can fit tightly to various irregular surfaces to ensure a sealing effect.

[0067] In addition, the housing 10 includes a first air duct cover plate 91 extending along the rear wall of the inner liner 4. The first air duct cover plate 91 is connected to the rear wall of the inner liner 4 and the first wall 431 to form the first air duct 11. The housing 10 also includes a second air duct cover plate 92 connected to the first air duct cover plate 91. A second air duct 12 is formed between the second air duct cover plate 92 and the top wall of the inner liner 4.

[0068] The first air duct 11 is directly connected to the refrigeration system 5, so that the cold air generated by the refrigeration system 5 can directly enter the first air duct 11. The first air duct 11 extends along the rear wall of the inner liner 4, forming a cold air transport passage located on the rear side of the storage compartment 3 in the vertical direction. The first air duct 11 has multiple back air outlets 111 connected to the storage compartment 3. The multiple back air outlets 111 are arranged in an array at intervals along the height direction of the first air duct 11, which can effectively guide the cold air generated by the refrigeration system 5 to different heights in the storage compartment 3, which helps the cold air to diffuse vertically in the storage compartment 3 and ensures that the cold air is evenly distributed in the storage compartment 3.

[0069] The second air duct 12 is connected to the first air duct 11, thus forming a cold air delivery path that extends from the back of the storage compartment 3 to the upper side of the storage compartment 3. The cold air is delivered to the second air duct 12 through the first air duct 11. The second air duct 12 extends along the top wall of the inner liner 4, forming a cold air delivery passage in the front and back direction, which helps the cold air to diffuse laterally within the storage compartment 3.

[0070] The second air duct 12 has multiple top air outlets 121 connected to the storage compartment 3 on its front side. At the same time, it can further distribute the cold air from the first air duct 11 to the front side of the storage compartment 3. The multiple top air outlets 121 are arranged in an array at intervals along the second air duct 12, which effectively solves the problem of excessively high local temperature in the front load area near the door 20 due to uneven distribution of cold air, and excessively low local temperature in the rear load area near the rear wall of the inner liner 4 due to excessive cold air. This improves the uniformity of cold air in the storage compartment 3, enhances the refrigeration or freezing effect of items in the storage compartment 3, and improves the energy efficiency of the refrigeration system 5.

[0071] In summary, the refrigeration equipment 100 of this utility model, by setting a return air interface 612 matching the return air vent 42 of the inner liner 4 and an air inlet interface 613 matching the air inlet vent 41 of the inner liner 4 on the machine compartment partition 6 between the inner liner 4 and the refrigeration system 5, and by using the first connector 7 and the second connector 8 to firmly connect the return air interface 612 and the air inlet interface 613 to the inner liner 4 respectively, not only improves the accuracy of the connection between the refrigeration equipment 100 and the inner liner 4, simplifies the installation process, and improves the assembly efficiency, but also ensures the smooth transmission of cold air, reduces cold leakage, and improves the refrigeration efficiency and refrigeration effect.
