Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a detachable structure for the inner liner of a refrigeration machine. Background Technology

[0002] A Chinese patent with publication number CN215665233U discloses a split-type household refrigerated trash can, which includes a base and a trash can body placed on the base. A semiconductor cooling chip is provided on the base. The cold end of the semiconductor cooling chip is exposed and in contact with the trash can body. The hot end of the semiconductor cooling chip is located inside the base. A ventilation structure is provided on the base to dissipate heat from the hot end of the semiconductor cooling chip.

[0003] However, the above-mentioned trash can has the following drawbacks: the trash can body and the base are designed separately, but the inner liner is fixedly connected to the trash can body. When emptying the trash, the trash can body is separated from the base and the trash in the inner liner is poured out. However, the trash can body is relatively heavy and not easy to lift, which urgently needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable inner liner structure for a refrigeration unit, which allows the inner liner to be disassembled and transported separately from the main body of the refrigeration unit, and results in a more compact overall structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a detachable liner structure for a refrigeration unit, comprising a refrigeration unit body, the refrigeration unit body having an upwardly opening barrel cavity, and a detachable liner inserted into the barrel cavity; A handle is rotatably connected to the inner liner, and the handle has an outwardly bent extraction part. The main body of the refrigeration unit has an avoidance notch on the upper surface of the edge of the barrel cavity corresponding to the extraction part. A storage space is formed between the main body of the refrigeration unit and the outer wall of the inner liner at the opening of the barrel cavity. The avoidance notch is connected to the storage space. When the inner liner is placed in the barrel cavity and the handle is stored in the storage space, the extraction part is hidden in the clearance notch.

[0006] By adopting the above technical solution, when it is necessary to remove or empty the food from the inner liner, the operator only needs to use the handle to pull the inner liner out of the refrigeration unit's main chamber, and then carry it by hand to the garbage disposal area for emptying. Alternatively, a garbage bag can be placed in the inner liner during use. When emptying the garbage, the garbage bag can be transported to the disposal area through the inner liner, and then the garbage bag can be removed from the inner liner and disposed of. This effectively avoids the possibility of the garbage bag breaking when carried alone. Other application scenarios also include... Fresh ingredients are placed in the inner liner, and then the inner liner containing the ingredients is placed into the refrigeration chamber for refrigeration. The detachable structure of the inner liner makes it more flexible to use and facilitates the operator's placement and retrieval of ingredients. In addition, when the inner liner is inserted into the refrigeration unit's main chamber, the handle is stored in the storage space between the refrigeration unit's main body and the outer wall of the inner liner. At this time, the lifting part of the handle is hidden in the clearance notch, which improves the overall compactness and aesthetics of this utility model. It has the effect that the inner liner can be disassembled and transported separately from the refrigeration unit's main body, and the overall structure is more compact.

[0007] A further feature of this invention is that the outer wall of the inner liner has a smooth cylindrical structure, and the barrel cavity is configured as a straight cylindrical cavity structure corresponding to the inner liner.

[0008] By adopting the above technical solution, compared with the polygonal inner liner structure on the market, the inner liner of this utility model adopts a smooth cylindrical structure, combined with a straight cylindrical cavity structure, so that the inner liner can be accurately positioned without distinguishing the direction when inserted, making the operation more convenient.

[0009] A further feature of this invention is that the inner liner includes a handle mounting portion for mounting a handle and a storage portion located below the handle mounting portion. The handle mounting portion has a cylindrical structure, and the diameter of the storage portion gradually decreases from top to bottom.

[0010] By adopting the above technical solutions, the handle mounting part of the straight cylinder structure facilitates the smooth rotation of the handle, and the storage part adopts a conical surface design with a guiding effect, which can improve the smoothness of inserting the storage part into the barrel cavity.

[0011] A further feature of this invention is that the main body of the refrigeration unit includes a shell and a cooling outer liner disposed within the shell. The outer wall of the inner liner is in close contact with the inner wall of the cooling outer liner. The shell includes an annular protrusion located at the top of the cavity, and the clearance notch is formed on the upper surface of the annular protrusion.

[0012] By adopting the above technical solution, heat exchange is achieved between the inner liner and the outer liner through contact.

[0013] A further feature of this invention is that the upper end of the cooling outer liner is bent upward to form a lower step, and the bottom of the annular protrusion is bent downward to form an upper step corresponding to the lower step. The upper step and the lower step are engaged, and the inner side of the annular protrusion and the outer wall of the inner liner form the storage space above the upper step.

[0014] By adopting the above technical solution, the interlocking effect of the upper and lower steps is used to improve the connection between the annular protrusion and the cooling outer shell, while the area above the upper step provides space for the hidden storage of the handle.

[0015] A further feature of this invention is that the inner wall of the inner liner is provided with an installation component, the installation component includes a bushing portion, a through hole is provided through the inner liner, the bushing portion passes through the through hole, and the handle end is hinged to the bushing portion via a hinge shaft, so that the handle is hinged to the outer wall of the inner liner.

[0016] By adopting the above technical solution, the end of the handle can rotate relative to the bushing of the mounting component via the hinge shaft, while the mounting component is relatively fixed to the inner wall of the inner liner, allowing the handle to rotate relative to the inner liner via the hinge shaft.

[0017] A further feature of this invention is that: two handles are provided, the two handles are symmetrically hinged to the outer wall of the inner liner, and each mounting component is provided with two bushing portions, and the pins of the two handles located on the same side are connected to the corresponding different bushing portions on the same mounting component.

[0018] By adopting the above technical solution, the symmetrically arranged handles can improve the load-bearing capacity of the handles and effectively prevent the handles from breaking due to excessive weight of the stored items in the inner liner.

[0019] A further feature of this invention is that a sealing ring is provided on the outer sleeve of the bushing portion, and the sealing ring is located on the inner or outer side of the inner liner and is sealed to fit the through hole.

[0020] By adopting the above technical solution and adding a sealing ring, odors in the inner liner can be prevented from leaking out through the gap between the bushing and the through hole.

[0021] A further feature of this invention is that the main body of the refrigeration unit is provided with a refrigeration device at the bottom of the cooling outer liner, the refrigeration device being used to cool the cooling outer liner.

[0022] By adopting the above technical solution, the refrigeration device can cool the outer liner, which then exchanges heat with the inner liner, thereby achieving the cooling of the inner liner.

[0023] A further feature of this invention is that the refrigeration device includes a semiconductor refrigeration component, which has a refrigeration end and a heating end. The refrigeration end is used to exchange heat with the cooling outer liner for refrigeration. The heating end is connected to a heat dissipation device. The main body of the refrigeration unit is provided with an air inlet and an air outlet. The heat dissipation device is used to draw airflow in through the air inlet and exchange heat with the heating end, and then discharge the heat through the air outlet.

[0024] In summary, this utility model has the following beneficial effects: The system employs a design with a barrel cavity on the main body of the refrigeration unit. A removable inner liner is inserted into this cavity, and a handle is rotatably connected to the outer wall of the inner liner. To remove or empty the food from the inner liner, the operator simply uses the handle to pull the inner liner out of the barrel cavity and then carries it to the waste disposal area. Alternatively, a garbage bag can be placed inside the inner liner. When emptying the garbage, the bag can be transported to the disposal area via the inner liner, and then the garbage bag can be removed from the inner liner and disposed of. This effectively avoids the risk of food spillage when carrying the garbage bag alone. Even in the event of a breakage, fresh ingredients can still be placed in the inner liner in other usage scenarios, and then the inner liner containing the ingredients can be placed into the refrigeration chamber for refrigeration. The detachable structure of the inner liner makes it more flexible to use and facilitates the operator's placement and retrieval of ingredients. In addition, when the inner liner is inserted into the refrigeration unit's main chamber, the handle is stored in the storage space between the refrigeration unit's main body and the outer wall of the inner liner. At this time, the lifting part of the handle is hidden in the clearance notch, which improves the overall compactness and aesthetics of this utility model. It has the effect that the inner liner can be disassembled and transported separately from the refrigeration unit's main body, and the overall structure is more compact. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] A detachable structure for the inner liner 3 of a refrigeration unit, such as Figures 1-9 As shown, the device includes a refrigeration unit 1 with an upward-opening cavity 101. An inner liner 3 is detachably inserted into the cavity 101, and the inner liner 3 has an upward-opening refrigerator compartment. A handle 6 is rotatably connected to the inner liner 3, and the handle 6 includes a lifting section 61 located in the center and bent outwards. A clearance notch 102 is provided on the upper surface of the edge of the cavity 101 corresponding to the lifting section 61. A storage space 103 is formed between the refrigeration unit 1 and the outer wall of the inner liner 3 at the opening of the cavity 101, and the clearance notch 102 communicates with the storage space 103. When the inner liner 3 is placed in the cavity 101 and the handle 6 is stored in the storage space 103, the lifting section 61 is hidden in the clearance notch 102. The outer wall of the inner liner 3 is smooth. The inner liner 3 has a cylindrical structure, with the barrel cavity 101 corresponding to a straight cylindrical cavity structure. Compared to the polygonal inner liner structures on the market, the inner liner 3 of this invention adopts a smooth cylindrical structure. Combined with the straight cylindrical cavity structure of the barrel cavity 101, the inner liner 3 can be accurately positioned without distinguishing the direction when inserted, making operation more convenient. The inner liner 3 includes a handle mounting part 31 for installing the handle 6 and a storage part 32 located below the handle mounting part 31. The handle mounting part 31 has a straight cylindrical structure, and the diameter of the storage part 32 gradually decreases from top to bottom. The straight cylindrical structure of the handle mounting part 31 facilitates the smooth rotation of the handle 6, and the conical design of the storage part 32 has a guiding effect, which can improve the smoothness of the insertion of the storage part 32 into the barrel cavity 101.

[0037] like Figures 1-6As shown, the main body 1 of the refrigeration unit includes an outer shell 11 and a cooling outer liner 2 disposed inside the outer shell 11. The outer wall of the inner liner 3 is in close contact with the inner wall of the cooling outer liner 2. The outer shell 11 includes an annular protrusion 111 located at the top of the cavity 101. An avoidance notch 102 is opened on the upper surface of the annular protrusion 111, so that the inner liner 3 can exchange heat through contact with the cooling outer liner 2. The upper end of the cooling outer liner 2 is bent upward to form a lower step 21. The bottom of the annular protrusion 111 is bent downward to form an upper step 1111 corresponding to the lower step 21. The upper step 1111 and the lower step 21 are engaged. The inner side of the annular protrusion 111 and the outer wall of the inner liner 3 form a storage space 103 above the upper step 1111. The engagement of the upper step 1111 and the lower step 21 improves the connection between the annular protrusion 111 and the cooling outer liner 2. At the same time, the area above the upper step 1111 provides space for the hidden storage of the handle 6.

[0038] like Figures 2-8 As shown, the inner wall of the inner liner 3 is provided with a mounting member 5, which includes a bushing portion 51. A through hole 33 is provided through the inner liner 3, and the bushing portion 51 passes through the through hole 33. The end of the handle 6 is hinged to the bushing portion 51 via a hinge shaft 4, so that the handle 6 is hinged to the outer wall of the inner liner 3, allowing the end of the handle 6 to rotate relative to the bushing portion 51 of the mounting member 5 via the hinge shaft 4. The mounting member 5 is relatively fixed to the inner wall of the inner liner 3, allowing the handle 6 to rotate relative to the inner liner 3 via the hinge shaft 4. There are two handles 6, which are symmetrically hinged to the outer wall of the inner liner 3. Each mounting component 5 has two bushing portions 51. The pins of the two handles 6 located on the same side are connected to the corresponding different bushing portions 51 on the same mounting component 5. The symmetrical arrangement of the handles 6 can improve the load-bearing capacity of the handles 6 and effectively prevent the handles 6 from breaking due to excessive weight of the stored items in the inner liner 3. The bushing portion 51 is covered with a sealing ring 52. The sealing ring 52 is located on the inner or outer side of the inner liner 3 and is sealed to the through hole 33. The addition of the sealing ring 52 can prevent the odor in the inner liner 3 from leaking out through the gap between the bushing portion 51 and the through hole 33.

[0039] like Figures 1-5 As shown, the main body 1 of the refrigerator is provided with a refrigeration device at the bottom of the cooling outer liner 2. The refrigeration device is used to cool the cooling outer liner 2. The cooling outer liner 2 can then exchange heat with the inner liner 3, thereby achieving the cooling of the inner liner 3. The refrigeration device includes a semiconductor refrigeration component 12, which has a cooling end and a heating end. The cooling end is used to exchange heat with the cooling outer liner 2 for cooling. The heating end is connected to a heat dissipation device 13. The main body 1 of the refrigerator is provided with an air inlet 14 and an air outlet 15. The heat dissipation device 13 is used to draw air in from the air inlet 14 and exchange heat with the heating end, and then discharge the heat from the air outlet 15.

[0040] The basic working principle of this utility model is as follows: A barrel cavity 101 is opened on the main body 1 of the refrigeration unit. An inner liner 3 is detachably inserted into the barrel cavity 101. A handle 6 is rotatably connected to the outer wall of the inner liner 3. When it is necessary to take out or pour out the food in the inner liner 3, the operator only needs to use the handle 6 to pull the inner liner 3 out of the barrel cavity 101 of the main body 1 of the refrigeration unit, and then carry the inner liner 3 to the garbage dumping point for dumping. Alternatively, a garbage bag can be placed in the inner liner 3 during use. When dumping garbage, the garbage bag can be transported to the garbage dumping point through the inner liner 3, and then the garbage bag containing garbage can be taken out of the inner liner 3 and thrown away. This can effectively avoid carrying the garbage bag alone. In the event of a broken garbage bag, fresh ingredients can still be placed in the inner liner 3 in other usage scenarios, and then the inner liner 3 containing the ingredients can be placed into the chamber 101 for refrigeration. The detachable structure of the inner liner 3 makes it more flexible to use and facilitates the operator's placement and retrieval of ingredients. In addition, when the inner liner 3 is inserted into the chamber 101 of the refrigeration unit 1, the handle 6 is stored in the storage space 103 between the refrigeration unit 1 and the outer wall of the inner liner 3. At this time, the extraction part 61 of the handle 6 is hidden in the clearance notch 102, which improves the overall compactness and aesthetics of this utility model. It has the effect that the inner liner 3 can be disassembled and transported separately from the refrigeration unit 1, and the overall structure is more compact.

[0041] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
