[0041] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0042] For ease of description, the directions in this application are as follows: front, back, left, right, up, and down. Figure 1 As shown, the depth of a storage room refers to the front-to-back direction, the width refers to the left-to-right direction, and the height refers to the up-to-down direction. Additionally, the length of the matrix refers to its length along the left-to-right direction, and the width refers to its width along the front-to-back direction.

[0043] Combination Figures 1 to 10As shown, this embodiment of the present disclosure provides a refrigeration device, which includes a housing and a shelf 30. The housing defines a connected air duct 201 and a storage chamber 101, and a cooling airflow flows within the air duct 201. The shelf 30 is disposed within the storage chamber 101. The shelf 30 has a first air outlet 302, and the top wall of the storage chamber 101 has a second air outlet 401. Both the first air outlet 302 and the second air outlet 401 are connected to the air duct 201, so that the airflow in the air duct 201 flows into the storage chamber 101 through the first air outlet 302 and the second air outlet 401, respectively.

[0044] In this embodiment, the shelf 30 is located within the storage compartment 101. The first air outlet 302 on the shelf 30 allows air to flow through the height of the storage compartment 101, improving the uniformity of airflow and temperature along the height of the storage compartment 101. A second air outlet 401 is located at the top of the storage compartment 101. The cooling airflow from the second air outlet 401 moves downwards and can also flow outwards, thus increasing the airflow volume in the depth and width of the storage compartment 101 to a certain extent, thereby improving the temperature uniformity across the depth and width of the storage compartment 101. The first air outlet 302 can compensate for the problem of uneven temperature along the height of the storage compartment 101 when the height of the storage compartment 101 is too high. Figure 9 As shown, the refrigeration equipment of this embodiment can achieve uniform airflow in the width, depth and height directions of the storage room 101 by setting the first air outlet 302 and the second air outlet 401, thereby improving the temperature uniformity of the storage room 101.

[0045] Optionally, such as Figures 2 to 4 As shown, the shelf 30 extends along the depth direction of the storage compartment 101, and there are multiple first air outlets 302, which are arranged sequentially at intervals along the extension direction of the shelf 30.

[0046] In this embodiment, the shelf 30 extends along the depth direction of the storage chamber 101, and the shelf 30 is provided with a plurality of first air outlets 302. In this way, the air volume of the shelf 30 in the depth direction of the storage chamber 101 is increased. Thus, the multiple shelves 30 can ensure the uniformity of air outlet in the depth direction of the storage chamber 101 while ensuring the uniformity of air outlet in the height direction, thereby further improving the uniformity of air outlet and temperature in the storage chamber 101.

[0047] Optionally, the first air outlet 302 is tilted downward along the air outlet direction.

[0048] In the embodiments of the present disclosure, the first air outlet 302 blows air downward, which cooperates with the second air outlet 401 at the top of the storage compartment 101, so as to increase the air volume at the lower part of the storage compartment 101 and further improve the air uniformity in the height direction of the storage compartment 101.

[0049] Optionally, when the first air outlet 302 is downwardly inclined, the angle between the first air outlet 302 and the horizontal direction is greater than or equal to 5° and less than or equal to 60°.

[0050] In the embodiments of the present disclosure, when the angle between the first air outlet 302 and the horizontal direction is less than 5°, the inclination angle of the first air outlet 302 is too small, and the downward flow of the air flowing out of the first air outlet 302 is too small, and part of the air flow flows in the horizontal direction, which leads to poor air supply uniformity in the height direction. Alternatively, when the shelf 30 is provided with the shelf plate 60, the inclination angle of the first air outlet 302 is too small, which may interfere with the shelf plate 60 and affect the air supply effect. When the angle between the first air outlet 302 and the horizontal direction is greater than 60°, the inclination angle of the first air outlet 302 is too large, so that most of the air flowing out of the first air outlet 302 flows downward, and the air flow to the middle part of the storage compartment 101 is small, which leads to poor air supply uniformity and temperature uniformity in the width direction of the storage compartment 101. Therefore, the inclination angle of the first air outlet 302 is set to be between 5° and 60°, so as to ensure the temperature uniformity in the height of the storage compartment 101 and to ensure the temperature uniformity in the width to a certain extent.

[0051] Optionally, when the first air outlet 302 is downwardly inclined, the angle between the first air outlet 302 and the horizontal direction is greater than or equal to 20° and less than or equal to 50°, or the angle between the first air outlet 302 and the horizontal direction is greater than or equal to 30° and less than or equal to 50°.

[0052] For example, the angle between the first air outlet 302 and the horizontal direction is 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55° or 60°.

[0053] Preferably, the angle between the first air outlet 302 and the horizontal direction is 45°.

[0054] Optionally, as Figure 2 and Figure 10As shown, the cabinet comprises an air duct piece 20, which encloses an air duct 201. The sidewall of the air duct piece 20 is provided with a side air outlet 202, and the top wall of the air duct piece 20 is provided with a top air outlet 203. The shelf 30 defines a first air outlet duct 301, and the first air outlet 302 communicates with the side air outlet 202 through the first air outlet duct 301. Alternatively, the top wall of the storage compartment 101 defines a second air outlet duct 40, and the second air outlet 401 communicates with the top air outlet 203 through the second air outlet duct 40.

[0055] In the embodiment of the present disclosure, the air duct piece 20 encloses the air duct 201. The airflow in the air duct 201 flows from the top air outlet 203 to the second air outlet duct 40, and then the airflow in the second air outlet duct 40 flows from the second air outlet 401 to the storage compartment 101, thereby forming the top air outlet of the storage compartment 101. The airflow in the air duct 201 can also flow from the side air outlet 202 to the first air outlet duct 301, and then the airflow in the first air outlet duct 301 flows through the first air outlet 302 to the storage compartment 101, thereby achieving the air outlet of the shelf 30. In the embodiment of the present disclosure, the airflow in the air duct 201 flows into the corresponding second air outlet 401 and first air outlet 302 through the corresponding top air outlet 203 and side air outlet 202. Therefore, the structure of the air duct 201 does not need to be changed. It is only necessary to correspondingly provide the side air outlet 202 and the top air outlet 203 according to the number of the first air outlet duct 301 and the second air outlet duct 40. This facilitates the processing of the air duct 201 and reduces the cost.

[0056] Optionally, the number of side air outlets 202 is multiple, and the number of side air outlets 202 is the same as and corresponds to the number of shelves 30. In this way, each shelf 30 can correspond to an air outlet, thereby further improving the air outlet uniformity of the storage compartment 101.

Optionally, the number of shelf groups in one storage compartment is one or multiple. When the storage compartment is provided with multiple shelf groups, the multiple shelf groups are arranged in sequence and spaced apart along the height direction of the storage compartment 101. In this way, the air outlet uniformity in the height direction of the storage compartment can be further improved. In particular, when the height of the storage compartment is large, the air supply uniformity can be effectively improved.

[0058] Since the first shelf and the second shelf are arranged opposite to each other along the width direction, the air supply uniformity in the width direction of the storage compartment 101 can also be improved. Moreover, since the first shelf and the second shelf are arranged opposite to each other along the width direction of the storage compartment 101, the first shelf and the second shelf can be conveniently arranged in cooperation with the loading device such as the shelf plate 60.
