The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

In the various drawings of the present invention, certain dimensions of structures or portions are exaggerated relative to other structures or portions for ease of illustration and, therefore, are used only to illustrate the basic structure of the subject matter of the present invention.

The utility model provides a refrigerating device, which is a device for refrigerating or freezing articles such as a refrigerator and a freezer.

As shown in fig. 1, 2 and 4, the refrigerating apparatus includes a cabinet 10, a refrigerator group 20 and a ventilation duct 30.

The box body 10 constitutes a main body of the refrigeration equipment and comprises a shell 11, an inner container 12 and a heat preservation space 13 arranged between the shell 11 and the inner container 12. The inner container 12 is arranged in the shell 11, and a storage compartment is formed inside the inner container 12. The heat-insulating space 13 is filled with a foaming material for heat insulation.

A refrigerating unit 20 is installed outside the cabinet 10 to provide cooling capacity required for refrigerating or freezing the contents in the storage compartment.

The ventilation duct 30 passes through the cabinet 10 to communicate the storage compartment with the inside of the refrigerator group 20. Compared with the ventilation structure formed by the existing spliced barrier strips, the ventilation pipeline 30 is simpler to form and is easier to assemble on the box body 10.

As shown in fig. 3, a partition 31 is provided inside the ventilation duct 30, and the partition 31 divides the inside of the ventilation duct 30 into an air intake opening 32 and a return air opening 33. The cold air in the refrigerating unit 20 enters the storage compartment from the air inlet 32, and the air in the storage compartment enters the refrigerating unit 20 from the air return opening 33 to be cooled, so that a cycle is formed.

The partition portion 31 is integrally formed with the inner wall of the ventilation duct 30, and the process of molding the ventilation duct 30 is simpler.

The ventilating duct 30 of the utility model separates the air inlet 32 and the air return 33 from the heat-insulating space 13, and can effectively prevent foaming materials in the heat-insulating space 13 from entering the air inlet 32 and the air return 33 during foaming.

As shown in fig. 2 and 3, in an embodiment of the present invention, the box 10 further includes a wind deflector 14 disposed inside the inner container 12, the wind deflector 14 divides the inside of the inner container 12 into a storage compartment located in front of the wind deflector 14 and an air duct located behind the wind deflector 14, and the wind deflector 14 is provided with a vent 141 communicating the storage compartment and the air duct; the air duct is communicated with the air inlet 32, and the storage compartment is communicated with the air return opening 33.

As shown in fig. 5, the refrigerator group 20 includes a box body 21, a compressor 22 disposed in the box body 21, a condenser 23, a capillary tube 24, an evaporator 25, and a blower fan 26. The compressor 22, the condenser 23, the capillary tube 24, and the evaporator 25 are connected in sequence by pipes to form a refrigeration circuit. A refrigerant flows through the refrigeration circuit. When the refrigeration circuit works, the refrigerant is compressed into high-temperature and high-pressure gas by the compressor 22, and then enters the condenser 23 for heat exchange to form a medium-temperature and high-pressure liquid refrigerant. The liquid refrigerant passes through the capillary tube 24, is throttled and depressurized, then enters the evaporator 25 to be subjected to heat exchange and gasification, and finally the gaseous refrigerant returns to the compressor 22 to complete the refrigeration cycle. The blower 26 is disposed between the intake vent 32 and the return vent 33 to circulate gas between the interior of the refrigeration unit 20 and the storage compartment.

Because the air temperatures at the air inlet 32 and the air return 33 are different, in order to avoid the decrease of the refrigeration efficiency caused by the heat exchange generated by the air at the positions of the air inlet 32 and the air return 33 in the partition part 31, a heat preservation cavity 311 for filling heat preservation material is arranged inside the partition part 31.

As shown in fig. 6, in one embodiment of the present invention, a first partition 31 is provided, the heat-insulating cavity 311 in the partition 31 is not communicated with the heat-insulating space 13, and the heat-insulating cavity 311 is filled with heat-insulating material such as heat-insulating cotton and heat-insulating foam in advance. Furthermore, the outer wall of the ventilation duct 30 is provided with an inwardly recessed groove 312 at a position corresponding to the position of the partition portion 31, when the box body 10 performs foaming operation, the foaming material in the heat preservation space 13 fills the groove 312, and the foaming material in the groove 312 is solidified to make the ventilation duct 30 more firm relative to the box body 10.

As shown in fig. 7, another embodiment of the present invention provides a second partition 31, and the insulated cavity 311 in the partition 31 communicates with the insulated space 13. Specifically, the ventilation duct 30 passes through the heat preservation space 13, and the heat preservation cavity 311 extends to the outer wall of the ventilation duct 30 to form an opening, and the opening is disposed in the heat preservation space 13. When the foaming operation is performed in the housing 10, the foaming material in the heat-insulating space 13 fills the heat-insulating cavity 311 to form a heat-insulating material. Furthermore, after the foaming material in the heat preservation cavity 311 is solidified, the ventilation duct 30 can be more firmly fixed relative to the box body 10.

The ventilation duct 30 having the first partition 31 is simple in molding process because it does not require an opening. The ventilation duct 30 having the second partition portion 31 is difficult compared to the ventilation duct 30 having the first partition portion 31, the molding process of the ventilation duct 30 is complicated, but the step of filling the thermal insulation material is omitted, and the ventilation duct 30 having the second partition portion 31 is located more firmly because the amount of the foamed material in the thermal insulation cavity 311 is greater than that in the groove 312.

As shown in fig. 1, the refrigerator unit 20 is disposed above the cabinet 10 to facilitate the installation and removal of the refrigerator unit 20.

As shown in fig. 6 and 7, the outer periphery of the ventilation duct 30 is further provided with a support portion 34 that protrudes in the horizontal direction out of the ventilation duct 30 and is supported on the top of the inner container 12. The inner container 12 is supported by a support portion 34 supporting the ventilation duct 30 to fix the position of the ventilation duct 30 before the foaming of the case 10.

As shown in fig. 4, a through hole 111 through which the ventilation duct 30 passes is provided at the top of the casing 11, and a window corresponding to the ventilation duct 30 is provided at the top of the inner container 12. The area of the through hole 111 in the horizontal plane is larger than the area of the support portion 34 in the horizontal plane. When the ventilation duct 30 is assembled, after the assembly of the belt box 10 is completed, the ventilation duct 30 passes through the through hole 111 from top to bottom until the supporting portion 34 is supported on the top of the inner container 12, the assembly of the ventilation duct 30 and the box 10 before the foaming of the box 10 is completed, and the large area of the through hole 111 enables the supporting portion 34 to smoothly pass through the through hole 111.

The periphery of the ventilation duct 30 is provided with a limiting part 35 which protrudes outwards from the ventilation duct 30 and is supported on the top of the box shell, and the limiting part 35 can further fix the position of the ventilation duct 30 before the box body 10 foams. In addition, during the foaming process of the box 10, the limiting portion 35 can prevent the foaming material from overflowing from the gap between the ventilation duct 30 and the inner wall of the through hole 111.

Further, the ventilation duct 30 is provided with a reinforcing rib 36 between the support portion 34 and the stopper portion 35, and the strength of the entire ventilation duct 30 is improved by the reinforcing rib 36.

The side of the ventilation duct 30 facing the refrigeration unit 20 is provided with a heat insulating structure 37 surrounding the air intake opening 32 and the air return opening 33. Specifically, the heat insulating structure 37 is a heat insulating material such as heat insulating cotton or heat insulating foam attached to the top of the ventilation duct 30. The heat insulation structure 37 can play a role of sealing, so as to prevent external air from entering the refrigeration unit 20 and the box body 10 from the space between the refrigeration unit 20 and the ventilation duct 30, and the heat insulation structure 37 can reduce the loss of cold energy from the space between the refrigeration unit 20 and the ventilation duct 30.

Further, the ventilation duct 30 has a filter structure 38 disposed in the intake opening 32 and the return opening 33. The filter structure 38 is used to prevent items in the storage compartment from entering the refrigeration unit 20. The filter structure 38 includes a plurality of first rods 381 parallel to the partitions 31 and a plurality of second rods 382 perpendicular to the partitions 31. By the staggered first rod 381 and the second rod 382, articles in the storage compartment are effectively blocked, and the condition that the articles in the storage compartment are stacked too high and extend into the ventilation duct 30 to block the ventilation duct 30 can be prevented.

Both ends of the first rod 381 are connected to the inner walls of both sides of the ventilation duct 30, respectively, one end of the second rod 382 is connected to the inner wall of the ventilation duct 30, and the other end is connected to the partition 31. Accordingly, the filter structure 38 may also serve to increase the overall strength of the ventilation duct 30.

The ventilation duct 30 and the partition part 31 and the filtering structure 38 which are arranged in the ventilation duct 30 are integrally formed injection molding parts, so that the production process of the ventilation duct 30 is simplified, and the assembly efficiency of refrigeration equipment is improved.
