[0022] The specific implementation of the air baffle structure without wind feeling provided by the present application is further described in combination with the drawings and embodiments.

[0023] An air baffle structure without wind feeling is used to be installed on a foamed liner of a refrigerator and form an air duct structure with the foamed liner, comprising an air baffle body 1 and an air baffle 2. The surface of the air baffle body 1 is provided with a plurality of air outlets 7 from top to bottom. The air baffle 2 is arranged at each air outlet 7. It is worth mentioning that the surface of the air baffle 2 is uniformly distributed with a plurality of wind dispersing holes 21 for dispersing cold air.

[0024] Embodiment 1:

[0025] The left and right sides of the air outlet 7 are provided with sliding grooves 6; the two ends of the air baffle 2 are provided with sliding blocks corresponding to the positions of the sliding grooves 6; the air baffle 2 is connected with the sliding grooves 6 on the left and right sides of the air outlet 7 through the sliding blocks. In use, the user only needs to manually slide the air baffle to the front end of the air outlet for shielding, as shown in Figure 1 .

[0026] Embodiment 2:

[0027] Different from embodiment 1, the air baffle 2 and the air outlet 7 are arranged together in this embodiment to form an integrated air outlet structure. Specifically, the four end faces of the air outlet 7 are provided with clamping grooves; the air baffle 2 is provided with clamping blocks corresponding to the positions of the clamping grooves; the air baffle 2 is clamped with the clamping grooves on the four end faces of the air outlet 7 through the clamping blocks. This arrangement does not need to be manually operated by the user in use, and is more convenient and fast, and is convenient to disassemble and assemble, as shown in Figure 2 .

[0028] It is worth noting that the connection relationship between the air baffle 2 and the air outlet 7 includes but is not limited to clamping, sliding connection, fixed connection, etc., and the specific connection mode does not serve as a further limitation on the utility model.

[0029] Preferably, the air baffle 2 is made of elastic plastic material, which is not easy to be damaged by brittleness during installation, thereby ensuring the service life.

[0030] Further preferably, the inner side wall of the air baffle body 1 is provided with a wind shield 3 corresponding to the position of the air outlet 7, and the lower end of the wind shield 3 is provided with an air inlet 31.

[0031] More preferably, the top and left and right sides of the air baffle body 1 are provided with a plurality of clamping hooks 4, and the bottom of the air baffle body 1 is provided with a plurality of plug plates 5; the air baffle body 1 is fixed between the clamping hooks 4 and the plug plates 5 and the foamed inner container. It is worth noting here that the air baffle structure provided by the utility model is suitable for a refrigeration chamber or a freezing chamber, and can be used in a back air duct or a top or side air duct, which can effectively achieve the purposes of reducing air speed, uniform air outlet, reducing air feeling, and stabilizing the pressure in the chamber, and can also reduce the temperature fluctuation in the chamber, slow down the evaporation of water on the surface of food materials, and improve the preservation effect of food materials.

[0032] Tests showed that, while maintaining proper refrigeration for the food, to achieve a wind speed of less than 0.2 m / s ("windless" state) when cold air flows from the air outlet through the ventilation holes 21 to the food on the shelf, the diameter of the ventilation holes 21 should be between 1-6 mm. When cold air passes through the ventilation holes 21, the instantaneous wind speed increases due to the sudden reduction in space. However, because the multiple ventilation holes 21 disperse and limit the flow of cold air, the wind speed is reduced to below level 1 when the dispersed cold air reaches the food, thus achieving a "windless" effect. Specifically, when the air guide holes of the windless air deflector are selected with apertures of 1mm, 2mm, 3mm, 4mm, 5mm, and 6mm, the corresponding wind velocities when cold air reaches the food through the air guide holes are 0.2m / s, 0.18m / s, 0.1m / s, 0.001m / s, 0.001m / s, and 0.001m / s (all belonging to wind force level 0); while ordinary refrigerators use a conventional air deflector structure without an air guide, and the wind velocity when cold air reaches the food through the air outlet is about 0.25m / s (belonging to wind force level 1).

[0033] Compared to the fan panel structure of ordinary refrigerators, the following is a detailed data analysis and comparison in three aspects: humidity, temperature, and preservation performance:

[0034] In this experiment, the air guide plate with a diffuser hole diameter of 4mm was selected for the windless wind-sensing structure.

[0035] like Figures 3-5 As shown, the experimental results are as follows: The refrigerator with the windless air intake structure maintained an average relative humidity of 49.2% RH, while the average relative humidity of the ordinary refrigerator was 21.4% RH (see Table 1 below); The refrigerator with the windless air intake structure maintained an average temperature of 3.2℃, while the average temperature of the ordinary refrigerator was 6.3℃ (see Table 2 below); The weight loss rate of the refrigerator with the windless air intake structure was 10%, while the weight loss rate of the ordinary refrigerator was 23.5%.

[0036] In summary, refrigerators with a draftless air intake structure have higher average humidity, lower average temperature, and lower weight loss rate (weight loss rate refers to the proportion of water weight lost by food during storage to its original weight) compared to ordinary refrigerators. Therefore, in terms of humidity, temperature, and preservation, refrigerators with a draftless air intake structure provide superior storage results compared to ordinary refrigerators.
