DETAILED DESCRIPTION

[0026] See also Figure 1 The present invention provides a large-volume refrigerator, comprising a box body 1, wherein an inner liner 2 is disposed in the box body 1; an insulation layer is disposed between the box body 1 and the inner liner 2; preferably, the insulation layer is a foaming layer, and after the box body 1 and the inner liner 2 are assembled, a foaming agent is filled to form the foaming layer. Those skilled in the art can achieve this by known methods and materials.

[0027] At least one layer of partition member 3 is provided in the inner container 2; the upper and lower sides of the partition member 3 form storage compartments;

[0028] The partition member 3 is provided with an air inlet 31 and an air return port 32;

[0029] See also Figure 2 The storage room at the bottom layer is provided with an evaporator chamber 21 in which an evaporator is installed; an air supply port and an air return port are provided on the side wall of the evaporator chamber 21;

[0030] The evaporator chamber 21 of the present invention is provided with an air supply motor, which can send out a cold air flow from the air supply port, and generate a negative pressure in the evaporator chamber 21, forming a return air flow at the return air port, thereby realizing a refrigeration cycle in the inner tank 2.

[0031] As an embodiment, the partition member 3 of the present invention is two-layered, forming a refrigeration compartment, a variable temperature compartment and a freezing compartment from top to bottom in the inner tank 2. Those skilled in the art can adaptively set the installation position of the partition member 3 in the inner tank 2 according to the volume of each compartment.

[0032] The cold air in the storage compartment below the partition member 3 flows upward from the air inlet 31 into the storage compartment above; the return air in the storage compartment above the partition member 3 flows downward from the return air outlet 32 ​​into the storage compartment below. The cold air is transmitted step by step from the lower storage compartment to the upper storage compartment, and the return air is transmitted step by step from the upper storage compartment to the lower storage compartment; thus, different refrigeration temperatures are formed in the storage compartments at different levels to meet the storage needs of different types of items.

[0033] As an embodiment of the present invention, the air supply port, the air return port, the air inlet 31 and the air return port 32 are all arranged close to the rear side wall of the inner liner 2, so as not to hinder the placement of items and not to be easily blocked by items. At the same time, the airflow flows along the rear side wall of the inner liner 2, away from the opening position of the box body 1, reducing the loss of cooling capacity.

[0034] As an embodiment of the present invention, the partition member 3 has at least two layers; the air inlets 31 on each partition member 3 are arranged vertically opposite to each other, so that the cold air flow can be smoothly transported from the lower storage compartment to the upper storage compartment. The return air ports 32 of two adjacent partition members 3 are arranged in a staggered manner to extend the path of the return air flow, so that its coldness is fully exchanged with the items in the storage compartment, ensuring the refrigeration efficiency.

[0035] The present invention provides an air inlet 31 and an air return port 32 on the partition member 3, replacing the air duct structure on the rear wall of the inner container 2, releasing the volume, increasing the effective volume and depth of the storage compartment, and improving the customer experience.

[0036] Combination Figure 4 As an embodiment of the partition member 3 of the present invention, the partition member 3 includes an upper partition 34 and a lower partition 35, and an interlayer 36 filled with a heat insulating material is formed between the two; the partition member 3 of the present invention not only has a load-bearing function, but also has a heat insulating function, isolating the heat exchange of the storage compartments on the upper and lower sides of the partition member 3, and forming refrigeration temperatures with obvious differences in the two storage compartments to meet different refrigeration needs.

[0037] The heat insulating material of the present invention is preferably a foam layer. Figure 6 The side wall of the partition member 3 is provided with an injection port 39 for injecting a foaming agent into the interlayer 36 to form a foaming layer; Figure 3 A filling port 22 connected to the injection port 39 is provided on the side wall of the inner liner 2; during production, the partition member 3 is installed in the inner liner 2, and in the next process, a foaming agent is injected into the interlayer 36 through the filling port 22 to form a foaming layer.

[0038] Compared with the existing refrigerator partitions, the partition member 3 of the present invention has a foaming layer, which slightly increases its thickness, but the increase is limited and the thickness is increased in the vertical direction. The volume occupied by the increase is much smaller than the volume increased by eliminating the air duct structure on the rear wall of the inner tank 2. Therefore, under the premise of retaining the refrigeration air circulation function, the volume of the storage compartment is effectively increased.

[0039] Referring to FIG. 4 , as an embodiment of the partition member 3 of the present invention, a convex ring 33 is provided around the air inlet 31; the convex ring 33 is provided along the periphery of the air inlet 31 to form a cylindrical structure to guide the cold air flow upward; and the flow path of the cold air flow is extended so that it can be smoothly delivered to the storage compartment on the upper layer.

[0040] See also Figure 5 As an embodiment of the partition member 3 of the present invention, the partition member 3 is further provided with a guide tube 37 near the air inlet 31, and a guide channel 371 is provided in the guide tube 37; the two ends of the guide channel 371 are respectively provided with a lower opening and an upper opening; the cross section of the guide channel 371 narrows from the lower opening to the upper opening; a bunching effect is formed on the cold air flow, the flow rate of the cold air flow is accelerated, and the flow path is extended, so that it can be transported to a higher position in the storage room, so as to make full use of the cold amount and balance the temperature in the room.

[0041] Furthermore, a retaining edge 38 is provided on one side of the partition member 3 close to the opening of the inner container 2 to prevent items from rolling down.

[0042] As an embodiment, the inner walls of the two side panels and the rear panel of the box body 1 of the present invention are both attached with insulation panels 12; when the size of the box body 1 is determined, the insulation panels 12 can effectively block heat, reduce the thickness of the foaming layer, increase the size of the inner liner 2, and thereby increase the effective volume of the storage compartment.

[0043] Preferably, the insulation panel 12 of the present invention is a vacuum insulation panel; the thickness of the insulation panel 12 does not exceed 20 mm, and those skilled in the art can adaptively set the thickness value according to the actual specifications of the refrigerator.

[0044] Optionally, a groove for laying condenser pipes is provided on the plane where the insulation board 12 is in contact with the inner wall of the box body 1, so that the condenser is in contact with the inner wall of the box body 1 to facilitate heat dissipation.

[0045] As an embodiment, the bottom of the box body 1 of the present invention is also provided with a compressor chamber 11 accommodating a compressor, and a condenser is provided in the compressor chamber 11; setting the condenser in the compressor chamber 11 can further reduce the distance between the box body 1 and the inner tank 2, thereby increasing the effective volume of the refrigerator.

[0046] In summary, the present invention provides a large-capacity refrigerator. By opening an air inlet and an air return port on the partition member, the refrigeration air flow circulation of each storage compartment of the refrigerator is realized, the air duct structure on the rear wall of the inner tank is replaced, and the volume is released and converted into storage volume, thereby increasing the effective volume of the refrigerator and the depth of the storage compartment, and improving the use performance and customer experience.

[0047] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
