Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator cooler liners, and in particular to a universal cooler liner for single and dual-system refrigerators. Background Technology

[0002] Currently, air-cooled refrigerators mainly use single-system or dual-system refrigeration solutions. However, due to the differences in the air duct structure between the two systems, the refrigerator liner cannot be used interchangeably and needs to be matched separately, which increases the burden on production costs and efficiency.

[0003] Single-system refrigerators: These use a single refrigeration system (compressor, condenser, capillary tube, evaporator), where cold air is naturally diffused or forcibly circulated to the refrigerator and freezer compartments. The refrigerator compartment typically requires a single air duct inlet for both cold air delivery and recirculation.

[0004] Dual-system refrigerator: It adopts two independent refrigeration systems (refrigeration evaporator + freezing evaporator), and the refrigerator compartment and the freezer compartment are controlled separately. The refrigerator compartment liner needs to be equipped with an additional drainage structure to meet the drainage requirements of the evaporator condensate.

[0005] Because the air duct interfaces and functional requirements of single and dual systems are different, the refrigerator liners in existing technologies are not interchangeable, leading to the following problems:

[0006] 1. High mold cost: It is necessary to develop special refrigerator liners for single-system and dual-system refrigerators separately, which increases the investment in molds.

[0007] 2. Low production efficiency: The production line needs to switch between different cabinets, which affects assembly efficiency.

[0008] 3. Poor compatibility: The single-system refrigerator liner cannot adapt to the drainage requirements of a dual-system refrigerator, and vice versa, which limits the flexibility of product design.

[0009] Therefore, there is an urgent need for a universal refrigerator liner structure that can adapt to the air circulation requirements of a single system and meet the drainage requirements of a dual system, thereby improving production efficiency and reducing manufacturing costs.

[0051] Example 1

[0052] Reference Figures 1 to 6 The first embodiment of this utility model provides a universal refrigerator liner for single and dual systems, including a liner main body module 100, an air duct interface module 200, a single system adapter module 300, and a dual system adapter module 400.

[0053] The main body module 100 of the refrigerator adopts a one-piece molded plastic cavity structure, and its refrigerated compartment molded cavity 101 has a standardized length, width and height ratio. The bottom wall of the cavity is divided into a main installation area 102 and two secondary installation areas 103, with the main installation area 102 located in the middle of the bottom and the secondary installation areas 103 symmetrically distributed on both sides of the main installation area.

[0054] The air duct interface module 200 includes a main through hole 201 and a secondary through hole 202. The main through hole 201 is a rectangular through hole located in the center of the main installation area 102, with its four sides perpendicular to the bottom surface of the casing. The secondary through hole 202 is a rectangular strip-shaped through hole. The two sets of secondary through holes 202 are respectively set in the same position in the two secondary installation areas 103, forming a mirror symmetrical layout.

[0055] Single system adapter module 300: The first injection molded part 301 is interference-fitted with the main through hole 201 through the flange structure 500, and the upper opening of its air inlet channel is connected to the inner cavity of the refrigerator. The second injection molded part 302 consists of two symmetrically designed components, and the top of its return air channel 3021 is provided with an air outlet.

[0056] Both the first injection molded part 301 and the second injection molded part 302 include a freezer compartment connection part 303, which has: a horizontally extending mounting plate 3031 for tightly fitting with the top wall of the freezer compartment; and a vertically extending positioning baffle 3032 for tightly fitting with the side wall of the freezer compartment.

[0057] The dual-system adapter module 400 includes a third injection molded part 401 that is sealed to the main through hole 201. The third injection molded part 401 has a downwardly extending water receiving tank 4011 and a drainage channel 4012 arranged at the bottom of the water receiving tank 4011.

[0058] The main through hole 201 formed in the main mounting area 102 has a hole layout that constitutes a first standard interface; the secondary through holes 202 formed in each secondary mounting area 103 have a hole layout that constitutes a second standard interface; the first standard interface simultaneously meets the installation and positioning requirements of the first injection molded part 301 and the third injection molded part 401.

[0059] In practical use: When applied to a single-system refrigerator, cold air flows from the freezer compartment into the upper part of the refrigerator compartment through the air inlet duct 3011, while hot air returns to the freezer compartment through the return air ducts 3021 on both sides, forming a forced convection circulation. Each injection-molded part is connected to the refrigerator compartment or freezer compartment through the first sealing lip 501 and the second sealing lip 502 respectively (this can be achieved by welding or by drilling holes in the corresponding parts and using fasteners), ensuring efficient cold air transfer.

[0060] Example 2

[0061] Reference Figures 2 to 6 This is the second embodiment of the present invention, which differs from the first embodiment in that it provides an optimized implementation scheme based on the first embodiment. Specifically:

[0062] The flange structure 500 of the third injection molded part 401 adopts an "L"-shaped double-lip design, including:

[0063] The first sealing lip 501 is tightly fitted to the outer wall of the cold storage chamber forming cavity 101;

[0064] The second sealing lip 502 is integrally formed with the corresponding injection molded part body to form a waterproof seal, and the second sealing lip 502 is tightly fitted with the bottom wall of the cold storage chamber molding cavity 101.

[0065] The cross-section of the water receiving tank 4011 of the third injection molded part 401 is a tapered trapezoidal structure, and the drainage channel 4012 is provided with an anti-backflow bending part 4013, the lowest point of which is lower than the bottom surface of the water receiving tank 4011.

[0066] Installation method: In dual-system configuration, the third injection-molded part 401 is inserted into the main through hole 201 from the outside of the liner, and installed by welding or by drilling holes in the corresponding parts and using fasteners. The opening edge of the water tank 4011 is lower than the mounting plane of the refrigeration evaporator, and the outlet of the drain channel 4012 extends downwards to the compressor compartment.

[0067] Working mechanism: Condensate generated by the refrigeration evaporator collects along the inclined surface of the water receiving tank 4011 and is discharged through the drainage channel 4012. The anti-backflow bending part 4013 prevents cold air from leaking out. The standardized design of the main through hole 201 allows the same cabinet to be compatible with the installation of two types of injection molded parts; only the interface module needs to be replaced during conversion.

[0068] The above embodiments, through modular interface design and standardized hole layout, enable rapid conversion of the same refrigerator liner between single and dual systems (by punching through holes of different specifications in the refrigerator liner and designing matching injection molded parts, a universal refrigerator liner for single and dual systems can be achieved), adapting to the installation characteristics of different refrigeration systems.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
