[0035] Example:

[0036] See also Figure 1 , Figure 8-Figure 11 , this embodiment provides a refrigerator, including a cabinet 100 and an air guide cover.

[0037] An air inlet channel 101 and an air outlet channel 102 are provided at the bottom of the cabinet 100. A plurality of ventilation holes 11 are provided on the air guide cover, which is mounted on the cabinet 100. The ventilation holes 11 are connected not only to the air inlet channel 101 but also to the air outlet channel 102. Therefore, the airflow can enter the air inlet channel 101 through the ventilation holes 11 and reach the bottom of the cabinet 100, and the airflow at the air outlet of the air outlet channel 102 can also leave the bottom of the cabinet 100 through the ventilation holes 11.

[0038] See also Figure 2-Figure 7, the air guide cover comprises an air guide plate 1, an upper enclosure plate 2, a lower enclosure plate 3 and a plurality of partitions 4. In this embodiment, the air guide plate 1 extends along a first direction, and there are at least two ventilation holes 11 located on the air guide plate 1, and all ventilation holes 11 are arranged in sequence and spaced apart in the first direction. The upper enclosure plate 2 and the lower enclosure plate 3 are parallel to each other and perpendicular to the air guide plate 1, the upper enclosure plate 2 is fixed to the top edge of the air guide plate 1, and the lower enclosure plate 3 is fixed to the bottom edge of the air guide plate 1, thereby the air guide plate 1, the upper enclosure plate 2 and the lower enclosure plate 3 are surrounded to form a ventilation cavity 5, and it is not difficult to understand that the ventilation holes 11 are connected to the ventilation cavity 5. After the air guide cover is installed on the cabinet 100, the ventilation cavity 5 is also connected to the air inlet channel 101 and the air outlet channel 102.

[0039] The air outside the cabinet 100 needs to pass through the ventilation holes 11 and the ventilation cavity 5 in sequence to reach the air inlet of the air inlet channel 101, and the air at the air outlet of the air outlet channel 102 needs to pass through the ventilation cavity 5 and the ventilation holes 11 in sequence to reach the outside of the cabinet 100. Therefore, the airflow at the air inlet of the air inlet channel 101 and the airflow at the air outlet of the air outlet channel 102 are prone to interfere with each other in the ventilation cavity 5. The partition 4 is installed in the ventilation cavity 5, and the partition 4 is located between two adjacent ventilation holes 11. The partition 4 plays a certain role in separating the above two airflows, thereby reducing the mutual interference of the above two airflows in the ventilation cavity 5. Accordingly, the flow of the two airflows can be smoother, thereby improving the heat dissipation effect at the bottom of the cabinet 100.

[0040] The number of the partition plate 4 can be one or more. In order to effectively block the two airflows, at least one partition plate 4 is located between the air inlet of the air inlet channel 101 and the air outlet of the air outlet channel 102.

[0041] Preferably, the partition 4 abuts against the air guide plate 1 , the upper enclosure plate 2 and the lower enclosure plate 3 at the same time, whereby the partition 4 has an internal support effect on the ventilation cavity 5 to suppress deformation of the ventilation cavity 5 .

[0042] The upper enclosure 2 extends upward from the edge of the air guide plate 1 to form a mounting plate 6, and a mounting hole 61 is provided on the mounting plate 6, and screws can be installed at the mounting hole 61 to fix the mounting plate 6 on the cabinet 100. The mounting plate 6 is also provided with an avoidance hole 62, and the avoidance hole 62 can be used for the electric push rod on the cabinet 100 to move telescopically.

[0043] See also Fig. 9 The cabinet 100 is provided with an adjustment bracket 103, an adjustment bolt 104 is fixed on the adjustment bracket 103, an adjustment nut 105 is threadedly connected to the adjustment bolt 104, and the adjustment nut 105 is adjusted by rotating and lifting on the adjustment bolt 104 to adjust the distance between the cabinet 100 and the ground, and the inclination angle of the cabinet 100 on the ground. The matching structure and matching relationship between the adjustment nut 105 and the cabinet 100 are prior art, and will not be described in detail in this embodiment.

[0044] See also Figure 3 , Figure 4 , Figure 6 and Figure 7 The end of the air guide plate 1 extends in a direction away from the mounting plate 6 to form a first side plate 12. The edge of the first side plate 12 away from the mounting plate 6 is provided with a first baffle 13. The upper enclosure 2, the first side plate 12 and the first baffle 13 are surrounded to form an avoidance groove 14. Fig.11 The adjusting bracket 103 , the adjusting bolt 104 and the adjusting nut 105 can all be accommodated in the avoidance groove 14 , and the side wall of the avoidance groove 14 can shield and protect the adjusting bracket 103 , the adjusting bolt 104 and the adjusting nut 105 .

[0045] Preferably, the first baffle 13 extends away from the edge of the first side plate 12 toward the mounting plate 6 to form a second side plate 15 , and the second side plate 15 can also shield the adjustment bracket 103 , the adjustment bolt 104 and the adjustment nut 105 .

[0046] See also Figure 6 , Figure 7 and Fig.11 The end of the lower enclosure plate 3 and the second side plate 15 are spaced apart to provide the space required for the adjusting nut 105 to rotate and rise and fall on the adjusting bolt 104 .

[0047] See also Figure 6 and Figure 7 A clamping rib 131 is provided on the first baffle 13 , and the clamping rib 131 is located in the avoidance groove 14 . In addition, the clamping rib 131 is spaced apart from the upper enclosure 2 , and the adjustment bracket 103 can be clamped between the clamping rib 131 and the upper enclosure 2 .

[0048] In this embodiment, two clamping ribs 131 are disposed in each avoidance groove 14 . The two clamping ribs 131 are disposed between the first side plate 12 and the second side plate 15 at intervals, and the adjusting bolt 104 is located between two adjacent clamping ribs 131 .

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
