Detailed Implementation

[0032] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0033] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0034] One embodiment of this utility model provides a refrigerator with a reasonable air duct design that solves the problem of supporting food baskets.

[0035] The freezer 100 in this embodiment includes an inner liner, which includes a first inner liner 10 and a second inner liner 20, such as... Figure 1 As shown, these two are connected to form a storage space 101 for storing items.

[0036] The materials of the first inner liner 10 and the second inner liner 20 can be flexibly selected according to actual needs. For example, the first inner liner 10 can be made of sheet metal to ensure structural strength, while the second inner liner 20 can be made of plastic to adapt to the needs of more deformation designs.

[0037] In addition, the first inner liner 10 can also be made of other materials with higher strength and less susceptibility to deformation due to heat and cold, and the second inner liner 20 can be made of materials suitable for injection molding products.

[0038] To clearly express the position and direction described in this embodiment, up and down are defined with reference to the direction of gravity. The freezer 100 in this embodiment can be a horizontal freezer 100, which is generally placed on a horizontal surface with its opening facing upwards. The freezer 100 is basically rectangular in shape, with the left and right sides along its length and the front and back sides along its width. The first inner liner 10 can be located above or below the second inner liner 20; in this embodiment, it is located below the second inner liner 20.

[0039] like Figures 2-5 As shown, the freezer 100 in this embodiment also includes a first air duct assembly 30. The first air duct assembly 30 is connected to the inner surface of the inner liner and protrudes towards the storage space 101. The air duct assembly includes a first reinforcing member 32 and a first air duct cover 34. The first reinforcing member 32 is fixedly connected to the inner surface of the inner liner, and the first air duct cover 34 is fixedly connected to the first reinforcing member 32. A first airflow channel 31 is provided between the first air duct cover 34 and the inner liner. The first air duct cover 34 exposes an air outlet or a return air outlet to the storage space 101.

[0040] The first air duct assembly 30 avoids complex opening or recessing processes on the first inner liner 10, such as forming an air vent by opening or forming an air duct by recessing, thereby maintaining the structural integrity and strength of the first air duct assembly 30 and enhancing the durability of the freezer 100.

[0041] The first air duct cover 34 is located below the first reinforcing member 32. A set of first air duct components 30 are provided on each of the opposite sides of the storage space 101. The upper surfaces of the two first reinforcing members 32 form a support surface for placing the food basket 60. The food basket 60 spans across the two first reinforcing members 32.

[0042] The first reinforcing member 32 not only participates in the enclosure of the airflow channel as part of the air duct, but also designs its upper surface as a support platform for the food basket 60.

[0043] In this way, the raised first air duct component 30 also serves as a support for the food basket 60. Users can place the food basket 60 securely on the first reinforcing member 32, which not only facilitates the storage and retrieval of items but also improves the practicality of the storage space 101. At the same time, the addition of the first reinforcing member 32 enhances the stability of the air duct structure, making it less prone to deformation during long-term use.

[0044] Furthermore, such as Figure 4As shown, the first air duct assembly 30 also includes a second reinforcing member 33 and a first air duct cover plate 34. The first air duct cover plate 34 is fixedly connected between the first reinforcing member 32 and the second reinforcing member 33. The first reinforcing member 32, the second reinforcing member 33 and the inner surface of the first inner liner 10 enclose the first airflow channel 31, so that cold air can flow smoothly in the closed channel, avoiding airflow leakage, thereby improving the cooling efficiency.

[0045] The first reinforcing member 32, the second reinforcing member 33, and the first air duct cover 34 all extend along the length of the freezer 100.

[0046] In this embodiment, both the first reinforcing member 32 and the second reinforcing member 33 are elongated, so that the food basket 60 can slide along the upper surface of the first reinforcing member 32 to any position in the left and right directions.

[0047] And such as Figure 2 and 3 As shown, the two first reinforcing members 32, which are set in the front and rear directions, jointly support the food basket 60 and play a role in stabilizing it.

[0048] Furthermore, a first slot 321 is provided on the first reinforcing member 32, and a second slot 331 is provided on the second reinforcing member 33. A sealing member 70 is provided in both the first slot 321 and the second slot 331. The first air duct cover plate 34 includes a first insert plate 342 and a second insert plate 343.

[0049] The gap between the first insert plate 342 and the first slot 321, and the gap between the second insert plate 343 and the second slot 331 are filled with sealing element 70, and the sealing element 70 may be provided with foam.

[0050] like Figure 3 As shown, the first insert plate 342 is inserted into the first slot 321 and is snapped into the first slot 321; the second insert plate 343 is inserted into the second slot 331 and is snapped into the second slot 331.

[0051] The first air duct cover 34 is fixed by a snap-fit ​​connection between the insert plate and the slot, and is supplemented by a seal 70, ensuring the ease of assembly and airtightness of the air duct assembly. This modular design simplifies the production and installation process, reduces the complexity of manual operation, and at the same time, the seal 70 in the slot effectively prevents cold air from leaking from the connection, improving the energy efficiency of the freezer 100, and making disassembly and assembly convenient for maintenance.

[0052] In addition, the tight fit between the insert plate and the slot enhances the stability of the cover. Even under vibration or temperature changes during the operation of the freezer 100, the cover can remain in a stable position, avoiding airflow disturbances or noise problems caused by loosening, and providing users with a better user experience.

[0053] The first reinforcing member 32 and the second reinforcing member 33 can both be made of metal material. The first reinforcing member 32 and the second reinforcing member 33 are fixedly connected to the first inner liner 10 by screws to improve the support effect.

[0054] The addition of the first reinforcing member 32 and the second reinforcing member 33 enhances the overall rigidity of the first inner liner 10, making it less prone to deformation when subjected to external pressure or temperature changes, thus ensuring the long service life and reliability of the freezer 100.

[0055] In this embodiment, the first air duct cover 34 closes the first airflow channel 31 and exposes the air outlet or return air outlet to the storage space 101.

[0056] The freezer 100 in this embodiment also includes a second air duct assembly 40.

[0057] The second air duct assembly 40 includes a groove 21 and a second air duct cover 41. The groove 21 is formed by recessing the second inner liner 20 in a direction away from the storage space 101 to form an embedded air duct on the second inner liner 20. The second air duct cover 41 closes the opening of the groove 21.

[0058] This not only facilitates the creation of complex air duct designs, but also avoids the air duct occupying storage space 101 or interfering with the food basket 60, thus maximizing the utilization rate of storage space 101.

[0059] Both the first air duct assembly 30 and the second air duct assembly 40 are equipped with air outlets or return air inlets to ensure that cold air can be evenly distributed within the storage space 101, thereby optimizing the cooling effect, reducing temperature fluctuations, and providing a stable low-temperature environment for item storage.

[0060] The Refrigerator 100 significantly improves design flexibility and functionality by designing the inner liner as two parts spliced ​​together and using different air duct structures.

[0061] In particular, some structures that are not easily damaged can be made into the first inner liner 10, and materials that are easier to deform can be made into the second inner liner 20. The needs of splicing the two types of inner liners can be met through raised air ducts and embedded air ducts.

[0062] Furthermore, the first inner liner 10 is made of sheet metal, and the second inner liner 20 is made of plastic.

[0063] By selecting different materials to manufacture the first inner liner 10 and the second inner liner 20, the freezer 100 achieves a good balance between performance and cost.

[0064] The first inner liner 10 is made of sheet metal, whose high strength and corrosion resistance enable it to withstand external impacts and wear during long-term use, ensuring the overall structural stability of the freezer 100.

[0065] The second inner liner 20 is made of plastic, which makes full use of the excellent heat insulation properties and processing flexibility of plastic. This not only reduces manufacturing costs, but also makes it easy to mold complex embedded air duct structures through injection molding.

[0066] This combination of materials not only meets the structural strength requirements of the air duct system, but also supports the lightweight and energy-saving design of the Refrigerator 100, making the product excellent in both practicality and economy.

[0067] In this embodiment, the first air duct components 30 on both sides of the storage space 101 each include a first air outlet 301, such as Figure 4 and 5 As shown. Figure 3 , 4 As shown in Figures 5 and 8, the two first air outlets 301 are arranged facing each other in the front-to-back direction; Figure 3 , 6 As shown in Figures 7 and 8, the second air duct assembly 40 includes a second air outlet 401, and the two second air outlets 401 are arranged facing each other in the front-to-back direction.

[0068] The second air duct assembly 40 includes a third slot 22 and a fourth slot 23 disposed in the groove 21. Both the third slot 22 and the fourth slot 23 are provided with a seal 70. The second air duct cover 41 includes a third insert plate 412 and a fourth insert plate 413.

[0069] like Figure 5 As shown, the third insert plate 412 is inserted into the third slot 22 and is snapped into the third slot 22; the fourth insert plate 413 is inserted into the fourth slot 23 and is snapped into the fourth slot 23.

[0070] The cover plate of the second air duct assembly 40 also adopts the connection method of insert plate and slot, and is sealed by the seal 70. This design forms a unified modular style with the first air duct assembly 30, which not only facilitates production and maintenance, but also ensures the airtightness and stability of the embedded air duct. Users or technicians can operate it easily, reducing maintenance costs and difficulties.

[0071] In addition, the freezer 100 also includes a door, and the first air outlet 301 and the second air outlet 401 are both inclined away from the door.

[0072] This avoids the loss of cold air caused by cold air blowing directly onto the door, and reduces the leakage of cold air when the door is opened, thereby improving the energy efficiency and refrigeration stability of the freezer 100.

[0073] On the other hand, the doors of horizontal freezers are generally made of glass to prevent cold air from blowing onto the door and to avoid condensation on the door.

[0074] Furthermore, such as Figure 3 As shown, the first inner liner 10 includes a first side wall 11 and a bottom wall 12, and the second inner liner 20 includes a second side wall 25. The first side wall 11 and the bottom wall 12 are fixedly connected at the edge.

[0075] The first side wall 11 is frame-shaped and manufactured separately. The first side wall 11 and the bottom wall 12 can be fixedly connected by welding, which has strong structural stability and makes the interior of the freezer 100 a flat and uniform storage space 101. This not only improves the appearance but also makes it easier for users to clean and maintain.

[0076] like Figure 7 As shown, the second sidewall 25 includes an insertion port 24 extending at its edge, into which the first sidewall 11 is inserted. The insertion port 24 enhances the connection strength between the first inner liner 10 and the second inner liner 20, and improves the sealing of the joint.

[0077] Furthermore, such as Figure 3 , 7 As shown in Figure 8, the inner surface of the first inner liner 10 and the inner surface of the second inner liner 20 are basically flush at the joint.

[0078] The smooth inner walls eliminate the steps or unevenness commonly found in traditional splicing methods, making the storage space 101 look neater and more aesthetically pleasing, reducing the possibility of dirt and grime accumulating, and making it easier for users to wipe and clean. Furthermore, the flush inner walls help ensure items are placed stably, avoiding tilting or sliding problems caused by uneven surfaces, providing users with greater hygiene and ease of use.

[0079] like Figure 8 As shown, the freezer 100 also includes an evaporator compartment 50. The evaporator compartment 50 is provided with a motor air outlet 51 and a main return air outlet. The first air outlet 301 and the second air outlet 401 are simultaneously connected to the motor air outlet 51. The first air outlet 301 and the second air outlet 401 are both connected to the evaporator compartment 50 through the main return air outlet.

[0080] This allows cold air to circulate efficiently within the storage space 101, avoiding airflow short-circuiting or dead zones, thereby improving cooling efficiency and temperature uniformity.

[0081] The complete circulation system also reduces the risk of evaporator frosting, extending the equipment's lifespan. Meanwhile, the front-to-back airflow design optimizes airflow paths, ensuring that cool air covers every corner of the storage space 101, providing a more stable low-temperature storage environment for items.

[0082] In this embodiment, the first air duct assembly 30 forms a raised air duct, and the second air duct assembly 40 forms an embedded air duct. On the one hand, it meets the needs of different inner liner materials, and different air ducts are used for inner liners made of different materials such as plastic parts and sheet metal parts.

[0083] On the other hand, the first reinforcing member 32 of the first air duct assembly 30 not only serves as a supporting component of the air duct structure, but its upper surface is also designed as a platform for placing the food basket 60, thus serving to enhance structural strength and expand storage function.

[0084] The second air duct component 40 does not occupy the space of the food basket 60, allowing the food basket 60 to have more space. This design makes full use of the space of the air duct component, increasing the practicality of the storage space 101.

[0085] Compared with the prior art, this embodiment has the following beneficial effects:

[0086] (1) The first air duct component 30 of the freezer 100 is protruding on the inner surface of the inner liner, which avoids complex opening or recessing processing on the inner liner, maintains the structural integrity and strength of the inner liner, solves the problem of damage to the inner liner caused by the air duct system, simplifies the manufacturing process of the inner liner, reduces production costs, and improves the durability and service life of the freezer 100.

[0087] (2) The first reinforcing member 32 of the first air duct assembly 30 is fixed to the inner side of the inner liner. Its upper surface serves as a platform for placing the food basket 60, providing a stable support for the food basket 60. This overcomes the limitations of traditional hanging food baskets 60 and enables flexible placement of the food basket 60, meeting the needs of modern families and commercial users for convenient storage.

[0088] (3) The freezer 100 overcomes the problem of difficult molding of inner liner in different positions and structures by splicing the first inner liner 10 and the second inner liner 20. It solves the problem that traditional single material inner liner cannot efficiently form complex air duct structures, greatly improving the design freedom and manufacturing feasibility of the air duct system. Since the first air duct component 30 is protruding on the first inner liner 10, it does not need to destroy the first inner liner 10, so that some structures that are not easy to be destroyed, such as the first inner liner 10, can be more complete and have higher structural strength. As for the second inner liner 20, which can be deformed more, an embedded air duct is set. In addition, since the second air duct component 40 is embedded in the second inner liner 20, it avoids interference with the food basket 60 and improves the utilization rate of the storage space 101.

[0089] In summary, the freezer 100 combines the support design of the first air duct component 30 and the food basket 60, which solves the problems of the air duct system damaging the inner liner structure, the inconvenience of placing the food basket 60, and the low utilization rate of the storage space 101. It significantly improves the performance, durability, and practicality of the freezer 100, and can better meet the needs of modern families and commercial users, with significant technical advantages and application value.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
