Fig. 1 is a schematic structural view of a wind guide hole structure for a refrigerating and freezing apparatus according to an embodiment of the present invention, and as shown in fig. 1 and referring to fig. 2 and 3, an embodiment of the present invention provides a wind guide hole structure for a refrigerating and freezing apparatus. The air guide hole structure 100 includes a first air guide plate 110 and a second air guide plate 120. The first air deflection 110 is horizontally disposed. The rear end of the second air guide plate 120 is disposed directly under the rear end of the first air guide plate 110, and the second air guide plate 120 extends upward and forward from the rear end thereof to the front end thereof, and the front end of the second air guide plate 120 is disposed under the rear of the front end of the first air guide plate 110.
The wind along the upper edge of the air outlet 211 is directly blown into the lower surface of the first wind deflector 110 so that the wind is not blown upward. The wind at the lower edge of the air outlet 211 is blown forward and upward under the diversion effect of the second air deflector 120, and after reaching the lower surface of the first air deflector 110, the air is blown out straight and forward under the diversion effect of the front end of the first air deflector 110. In the air guide hole structure 100 provided by the embodiment of the invention, cold air blown out from the air outlet 211 is blown out flatly and straightly under the flow guiding action of the first air guide plate 110 and the second air guide plate 120, so that the cold air is prevented from blowing out food materials straightly, a relatively high humidity environment is provided for preserving the food materials, and the fresh-keeping effect of the food materials is improved.
In some embodiments of the present invention, as shown in fig. 1 to 3, an extended surface of the upper surface of the second air deflection 120 passes through the first air deflection 110. That is, the length of the first air guide plate 110 in the front-rear direction is longer than the length of the second air guide plate 120 in the front-rear direction, so that the wind blown out from the lower edge of the air outlet 211 is blown out forward upward along the upper surface of the second air guide plate 120, and the wind is blown out straight forward by the flow guiding action of the first air guide plate 110. The ratio of the length of the first air guide plate 110 in the front-rear direction to the distance from the intersection line formed by the extension surface of the upper surface of the second air guide plate 120 and the lower surface of the first air guide plate 110 to the rear end of the first air guide plate 110 is 1.2 to 1.5. As shown in fig. 2, the length of the first air deflector 110 in the front-rear direction is L, the distance from the intersection line formed by the extension surface of the upper surface of the second air deflector 120 and the lower surface of the first air deflector 110 to the rear end of the first air deflector 110 is C, and l=η×c, where η is a first set coefficient, and η is 1.2 to 1.5.
In some embodiments of the present invention, a ratio of a distance between a rear end of the upper surface of the second air deflection 120 and the lower surface of the first air deflection 110 to a distance between a front end of the upper surface of the second air deflection 120 and the lower surface of the first air deflection 110 is 1.5 to 3. As shown in fig. 2, the distance between the rear end of the upper surface of the second air deflector 120 and the lower surface of the first air deflector 110 is a, the distance between the front end of the upper surface of the second air deflector 120 and the lower surface of the first air deflector 110 is a=ζ×a, where ζ is a second set coefficient, and ζ is 1.5 to 3. The value of a is a value given by a designer according to the specific required air quantity and the width of the air outlet 211, and the value of A can be calculated according to the value of a. The formula is simple and is convenient for design and calculation. Further, the distance between the front end of the second air deflector 120 and the rear end of the second air deflector 120 along the horizontal direction is D, and d= (a-a) cotα.
In some embodiments of the present invention, as shown in fig. 2, the length of the first air deflector 110 in the front-rear direction is L, the distance between the front end of the upper surface of the second air deflector 120 and the lower surface of the first air deflector 110 is a, and the angle between the second air deflector 120 and the horizontal plane is α. And α=arctan { [ a+η (ζ -1) ]/L }; wherein eta is a first set coefficient and eta is 1.2 to 1.5; ζ is the second setting coefficient, and ζ is 1.5 to 3.
As can be seen from the above formula, the included angle α between the second air deflector 120 and the horizontal plane is only related to the variable a, so that the included angle α between the second air deflector 120 and the horizontal plane can be controlled by only changing the distance a between the front end of the upper surface of the second air deflector 120 and the lower surface of the first air deflector 110. And the first air deflector 110 and the second air deflector 120 have simple structures and are convenient to design and manufacture. The air outlet direction of the air outlet of the air channel is ensured to have an initial air outlet angle alpha, so that the air outlet of the air channel is blown out as straight as possible.
In some embodiments of the present invention, the air guiding hole structure 100 further includes two vertically disposed side plates, each of which connects one of the same side edges of the first air guiding plate 110 and the second air guiding plate 120. The two side plates enable the air flow to be blown forward through the air guide hole structure 100, and air leakage from two sides is avoided, so that the refrigerating effect of the refrigerating and freezing device 200 is better.
Specifically, the front edge of each side plate is disposed vertically, directly below the front end of the first air deflection 110, and the lower edge of each side plate extends in a direction parallel to the upper surface of the second air deflection 120.

For example, more than 80% of the air flow, namely most of the air flow flows straightly in the direction away from the wall of the compartment, so that cold air is prevented from directly blowing food materials, a relatively high-humidity environment is provided for preserving the food materials, and the fresh-keeping effect of the food materials is improved.
In some embodiments of the present invention, as shown in fig. 4 and 5, the air supply structure includes a wind deflector 220, where the wind deflector 220 is horizontally disposed in the storage compartment 210 and below the air outlet 211, so as to ensure that the air flows out and is blown out smoothly in the storage compartment 210, thereby freezing the food.
In some embodiments of the present invention, the air supply structure includes an air guiding hole structure 100, and the air guiding hole structure 100 is the air guiding hole structure 100 in any of the above embodiments. And the rear end of the first air deflector 110 is disposed at the upper edge of the air outlet 211, and the rear end of the second air deflector 120 is disposed at the lower edge of the air outlet 211. The wind on the upper edge of the air outlet 211 is directly blown into the lower surface of the first air deflector 110, so that the wind cannot be blown onto the upper surface, and the wind on the lower edge of the air outlet 211 cannot be directly blown downwards due to the inclined angle alpha, so that the wind can be blown out straightly. Further, the width of the first air deflector 110 may be greater than the width of the air outlet 211.
In some embodiments of the present invention, as shown in fig. 4-6, a drawer 212 is disposed within the storage compartment 210, the drawer 212 being disposed below the air-blowing structure.
