Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to an air duct structure of a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items in a constant low temperature cold state. The cabinet contains a compressor and an ice maker for freezing, and there are many connectors in it, which provide sufficient auxiliary functions for the refrigerator. The refrigerator air duct is an important structure of the refrigerator body. The air duct in the refrigerator is generally installed at the back or side of the refrigerator. Its function is to discharge the hot air accumulated in the condenser from the inside of the refrigerator to ensure the temperature and humidity inside the refrigerator, so as to achieve the purpose of preservation. If there is a problem with the air duct in the refrigerator, it will affect the cooling effect of the refrigerator, which may cause it to fail to maintain the appropriate temperature and affect the quality of the food inside.

[0003] The existing Chinese patent with announcement number CN216080546U discloses an air duct assembly of a refrigerator and a refrigerator. The air duct assembly of the refrigerator includes an air duct cavity, a fan assembly, an air duct, a door assembly and an anti-water accumulation structure. The fan assembly includes a fan housing and a fan arranged in the fan housing. The fan housing is provided with a fan inlet and a fan outlet. The fan inlet is used to communicate with the evaporation bin of the refrigerator; the air duct inlet of the air duct is connected to the fan outlet, the door assembly is arranged in the air duct cavity, the door assembly includes a door body movably arranged to open and close the fan outlet or the air duct, and a driving device to drive the door body to move. The anti-water accumulation structure is used to prevent condensation water from accumulating at the door body, so as to solve the problem in the prior art that the door body loses its function due to being stuck due to the accumulation of condensation water and ice.

[0004] However, the above device has the following disadvantages: a blower, that is, a fan, is provided inside the refrigerator, and a dustproof net is generally provided on the outside of the air duct. Although the dustproof net is provided, it cannot prevent the entry of dust, but only greatly reduces the amount of dust entering. However, over time, the inner wall of the air duct will still be contaminated with dust. If it is not cleaned in time, it will affect the ventilation inside the air duct, greatly increase the power consumption of the refrigerator, and is not very practical.

[0005] Therefore, it is necessary to provide a refrigerator air duct structure to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide a refrigerator air duct structure, which adopts a first dustproof net and a sliding ring, and has the effect of facilitating the cleaning of dust on the inner wall of the air duct.

[0007] The above technical objective of the utility model is achieved through the following technical solutions: a refrigerator air duct structure, comprising a mounting seat, an air duct is fixedly mounted on one end of the mounting seat, a plurality of mounting rings are fixedly mounted on the inner wall of the air duct, a screw is rotatably connected between two of the mounting rings, a sliding rod is fixedly mounted between the remaining plurality of mounting rings, a slip ring is slidably mounted on the inner wall of the air duct, a fan is fixedly mounted on the inner wall of the slip ring, a second dustproof net is fixedly mounted on the inner wall of the slip ring, the second dustproof net is arranged on one side of the fan, the slip ring is threadedly connected to the screw, the slip ring is slidably connected to the sliding rod, a motor is fixedly mounted on the side wall of one of the mounting rings, the output end of the motor is drivingly connected to the screw, a rotating shaft is rotatably connected to the top end of one end of the air duct, a sealing cover is fixedly mounted on the side wall of the rotating shaft, and a first dustproof net is fixedly mounted inside the sealing cover.

[0008] By adopting the above technical scheme, when the refrigerator body is in operation, the sealing cover and the first dustproof net can play a preliminary dust filtering role. When a large amount of dust accumulates inside the air duct and needs to be cleaned, the dust on the first dustproof net is first processed and cleaned, and then the sealing cover is opened. After opening, the motor is controlled to rotate, and the motor drives the screw to rotate. Then, under the limiting action of the slide rod and the slip ring, the slip ring can slide inside the air duct. Since the slip ring and the inner wall of the air duct are in a tightly fitted state, the dust can be pushed to the position of the air duct outlet through the slip ring and the second dustproof net, and then cleaned, thereby achieving the cleaning of the inside of the air duct and increasing the practical performance and dust removal efficiency of the device.

[0009] The utility model is further configured as follows: a sealing ring is fixedly mounted on the side wall of the sealing cover.

[0010] By adopting the above technical solution, the sealing ring can increase the sealing performance of the sealing cover, prevent dust from entering the air duct through the sealing cover and the air duct gap, and improve the dustproof performance and sealing performance of the device.

[0011] The utility model is further configured as follows: torsion springs are provided at both ends of the rotating shaft, one end of the torsion spring is fixedly connected to the sealing cover, and the other end of the torsion spring is fixedly connected to the air duct.

[0012] By adopting the above technical solution, the function of the torsion spring is that when the sealing cover is opened, the sealing cover can be directly kept in a vertical state at the air duct opening without being fixed, thereby increasing the practical performance and dust removal efficiency of the device.

[0013] The utility model is further configured as follows: a plurality of threaded holes are provided on the side wall of the air duct, a plurality of nuts are threadedly mounted on the side wall of the sealing cover, and the plurality of nuts and the threaded holes are adapted to each other.

[0014] By adopting the above technical solution, the air duct and the sealing cover can be fixed by connecting the nut and the threaded hole, thereby increasing the stability of the device.

[0015] The utility model is further configured as follows: a plurality of heat dissipation fins are fixedly mounted on the outer side wall of the air duct.

[0016] By adopting the above technical solution, the heat dissipation fins can conduct the heat inside the machine body out through the heat dissipation fins, thereby increasing the practical performance and heat dissipation performance of the device.

[0017] The utility model is further configured as follows: a dustproof and static-electricity-proof layer is fixedly installed on the inner wall of the air duct.

[0018] By adopting the above technical solution, the function of the dust-proof electrostatic layer is to prevent dust from being adsorbed on the inner wall of the air duct through electrostatic action, thereby increasing the practicality and dust-proof performance of the device.

[0019] In summary, the utility model has the following beneficial effects: when the refrigerator body is in operation, the sealing cover and the first dustproof net can play a preliminary dust filtering role. When a large amount of dust accumulates inside the air duct and needs to be cleaned, the dust on the first dustproof net is first processed and cleaned, and then the sealing cover is opened. After opening, the motor is controlled to rotate, and the motor drives the screw to rotate. Then, under the limiting action of the slide rod and the slip ring, the slip ring can slide inside the air duct. Since the slip ring and the inner wall of the air duct are in a tightly fitted state, the dust can be pushed to the position of the air duct opening through the slip ring and the second dustproof net, and then cleaned, thereby achieving the cleaning of the inside of the air duct and increasing the practical performance and dust removal efficiency of the device.
