Technical Field

[0001] The utility model relates to the technical field of electric isolation devices, and more specifically to a refrigerator air duct structure. Background Art

[0002] At present, refrigerators are mainly divided into direct cooling and air cooling according to different refrigeration methods. When an air-cooled refrigerator is working, the fan sends the cold air generated by the evaporator into the refrigerator body through the supply air duct, and the warm air in the refrigerator body is sent back to the evaporator through the return air duct for rapid cooling. The air duct structure of existing air-cooled refrigerators is generally single-channel, but in the case of the current multi-chamber structure, it is necessary to set up multiple sets of ventilation systems, which makes the system more complex and the cost increased.

[0006] Furthermore, the baffle plates include two groups, an air supply channel is formed between the two groups of baffle plates, the air supply channel is communicated with the air outlet of the fan component, and a return flow cover located outside the air supply channel is also provided on the supporting plate, a return flow channel is formed between the return flow cover and the two groups of baffle plates, and the ventilation hole is located in the return flow channel.

[0007] Furthermore, a guide plate for guiding the wind in the air delivery channel to the return channel is provided in the return cover.

[0008] Furthermore, a baffle plate is provided between the return cover and the baffle plate to prevent the wind in the return channel from flowing out.

[0009] Furthermore, each of the reflux channels has at least two ventilation holes, and the two ventilation holes are respectively located at two ends of the reflux channel.

[0010] The beneficial effects of the utility model are as follows: a baffle is arranged at the air outlet of the fan component to separate the air supply channel, which can ensure that the air outlet of the fan component enters the ventilation holes on both sides of the baffle evenly, so as to realize one-to-two air supply to the room, reduce system complexity and reduce costs.

[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] In the case of the current multi-chamber structure, multiple sets of ventilation systems need to be set up accordingly, which makes the system more complex and the cost increases. Therefore, the utility model designs such a refrigerator air duct structure, such as Figure 1 As shown, it includes a bearing plate 1, on which a fan component 2 is provided, the fan component 2 includes a fan and a wind cover arranged outside the fan, a baffle plate 3 is provided on the bearing plate 1, and ventilation holes 4 penetrating the bearing plate 1 are also provided on the bearing plate 1 on both sides of the baffle plate 3, and the opening (air outlet) of the wind cover faces the baffle plate 3, so that the baffle plate 3 divides the output wind to the ventilation holes 4 on both sides of the baffle plate 3, which can ensure that the air output of the fan component 2 evenly enters the ventilation holes 4 on both sides of the baffle plate 3, so as to realize one-to-two air supply to the room, reduce system complexity and reduce costs.

[0015] Embodiment 1:

[0016] The baffle plate 3 includes two groups, and an air delivery channel 5 is formed between the two groups of baffle plates 3. The air delivery channel 5 is connected to the opening of the wind cover, that is, the two groups of baffle plates 3 are located on opposite sides of the opening of the wind cover. The carrier plate 1 is also provided with a return cover 6 located outside the air delivery channel 5. A return channel 7 is formed between the return cover 6 and the two groups of baffle plates 3. The return channel 7 is in an inverted "U" shape. The ventilation hole 4 is located in the return channel 7. A guide plate 8 for guiding the wind in the air delivery channel 5 to the return channel 7 is provided in the return cover 6, that is, two guide plates are provided in the return cover 6. 8. The two guide plates 8 are arranged in an "eight" shape, and a connected flat plate is also arranged between the two guide plates 8. When the wind in the air delivery channel 5 hits the flat plate, the two "eight" shaped guide plates 8 guide the wind into the two return channels 7.
