Abstract

The present disclosure provides an air duct assembly of a refrigerator, comprising: a main body, the main body being provided with an air inlet toward one side of the main body, a plurality of air outlets formed in areas of two sides of the main body, and an air-uniformizing partition plate provided on the main body and located above the air inlet, and the air-uniformizing partition plate divides the air entered from the air inlet into the areas of two sides of the main body and the air is discharged via the plurality of air outlets.

First claim

What is claimed is:

1. An air duct assembly, comprising:
a main body, the main body being provided with an air inlet, wherein the air inlet is provided below the main body and toward a corner of the main body;
a plurality of air outlets formed in areas surrounding the main body; and
an air-uniformizing partition plate provided on the main body with a protruding portion extending toward the air inlet;
wherein the air-uniformizing partition plate divides the air entered from the air inlet into the areas surrounding the main body and the air is discharged via the plurality of air outlets;
wherein the plurality of air outlets comprise:
a first air outlet provided on a first side of the main body closer to the air inlet;
a second air outlet provided at a top of the main body closer to the air inlet;
a third air outlet provided on a third side of the main body far from the air inlet;
a fourth air outlet provided at the top of the main body far from the air inlet; and
a deflecting plate provided between the third air outlet and the main body;
wherein the deflecting plate divides the air from the air inlet into the third air outlet and the fourth air outlet.

2. The air duct assembly according to claim 1 , wherein,
the air-uniformizing partition plate is provided with a round corner at a bottom of a side close to the third air outlet.

3. The air duct assembly according to claim 1 , wherein,
the air-uniformizing partition plate is provided with at least one of a wavelike structure or a zigzag structure on a side close to the third air outlet and on a side close to the first air outlet.

4. The air duct assembly according to claim 3 , wherein the third air outlet comprises:
a third upper air outlet, provided at an upper portion of a side of the main body farther from the air inlet;
a third middle air outlet, provided at a middle portion of a side of the main body farther from the air inlet;
a third lower air outlet, provided at a lower portion of a side of the main body farther from the air inlet.

5. The air duct assembly according to claim 4 , wherein,
a bottom of the third upper air outlet is provided with a first air guiding slope, and an angle between the first air guiding slope and the horizontal plane ranges from 20° to 45°.

6. The air duct assembly according to claim 4 , wherein,
a distance between the third upper air outlet and the third middle air outlet ranges from 50 mm to 150 mm;
a distance between the third lower air outlet and the third middle air outlet ranges from 50 mm to 150 mm.

7. The air duct assembly according to claim 3 , wherein the first air outlet comprises:
a first upper air outlet, provided at an upper portion of a side of the main body closer to the air inlet;
a first middle air outlet, provided at a middle portion of a side of the main body closer to the air inlet;
a first lower air outlet, provided at a lower portion of a side of the main body closer to the air inlet.

8. The air duct assembly according to claim 7 , wherein,
the bottom and the top of the first middle air outlet are each provided with a second air guiding slope, and an angle between the second air guiding slope and the horizontal plane ranges from 20° to 30°,
the bottom and the top of the first lower air outlet are each provided with a third air guiding slope, and an angle between the third air guiding slope and the horizontal plane ranges from 20° to 30°.

9. The air duct assembly according to claim 7 , wherein,
a distance between the first upper air outlet and the first middle air outlet ranges from 50 mm to 150 mm;
a distance between the first lower air outlet and the first middle air outlet ranges from 50 mm to 150 mm.

10. The air duct assembly according to claim 1 , wherein,
a thickness of the deflecting plate ranges from 5 mm to 12 mm.

11. The air duct assembly according to claim 1 , wherein,
a thickness of the air-uniformizing partition plate ranges from 5 mm to 12 mm; or
the ratio of the thickness of the air-uniformizing partition plate to a cross-sectional width of the air inlet ranges from 5% to 15%.

12. A refrigerator, comprising:
an air duct assembly, comprising:
a main body, the main body being provided with an air inlet, wherein the air inlet is provided below the main body and toward a corner of the main body;
a plurality of air outlets formed in areas surrounding the main body; and
an air-uniformizing partition plate provided on the main body with a protruding portion extending toward the air inlet;
wherein the air-uniformizing partition plate divides the air entered from the air inlet into the areas surrounding the main body and the air is discharged via the plurality of air outlets;
wherein the plurality of air outlets comprise:
a first air outlet provided on a first side of the main body closer to the air inlet;
a second air outlet provided at a top of the main body closer to the air inlet;
a third air outlet provided on a third side of the main body far from the air inlet;
a fourth air outlet provided at the top of the main body far from the air inlet; and
a deflecting plate provided between the third air outlet and the main body;
wherein the deflecting plate divides the air from the air inlet into the third air outlet and the fourth air outlet.

13. The refrigerator according to claim 12 , wherein the refrigerator further comprises:
a fan assembly, the fan assembly being connected to the air duct assembly.

14. The refrigerator according to claim 12 , wherein the refrigerator further comprises:
a refrigeration compartment, the refrigeration compartment being connected to the plurality of air outlets.
