Description

FIELD

The present disclosure relates to the field of household appliances, and in particular to an air duct assembly and a refrigerator.

BACKGROUND OF THE INVENTION

For refrigerators and other refrigeration products, there is a common problem: the internal temperature of the refrigerator is uneven, and there are two main reasons for the temperature unevenness: one is heat losses; the other is uneven flow of an air supply port.

At present, the cooling capacity inside the refrigerator is in the form of cold air which flows through the evaporator and is transported to various functional areas via the air duct. In this process, there are two parts of losses in the cooling capacity transported. One is the loss from the air duct, and the other is the heat loss caused by heat exchange with the wall after the cooling capacity enters the refrigerator. The uneven flow of the air supply port is caused by the unreasonable design of the air duct structure. A common problem is that there is uneven flow among different air supply ports on the left and right sides of the refrigerator, as well as the total air volume on the left and right sides of the refrigerator. This causes the cooling capacity carried by the cold air on the two sides to be inconsistent, resulting in uneven temperature inside the refrigerator body. Uneven temperature can adversely affect the food being stored, reducing the shelf life of the food, thereby seriously damaging the user's experience. Due to the size and internal functional structure, most of the air ducts are asymmetric. This will also result in uneven distribution of flow, resulting in temperature fluctuations and temperature differences, and causing many problems such as follows:

Disadvantage 1: Due to the asymmetric air duct structure, the air supply volume of each branched flow channel is uneven, resulting in a temperature difference inside the refrigerator;

Disadvantage 2: Due to the asymmetric air duct structure, the flow among symmetric air supply ports of each branched flow channel are uneven, resulting in a temperature difference inside the refrigerator;

Disadvantage 3: Due to the asymmetric air duct structure, an unreasonable air supply duct design will lead to increased flow resistance and obvious temperature fluctuations.

Disadvantage 4: Due to the asymmetric air duct structure, it is easy to generate aerodynamic noise.

BRIEF SUMMARY OF THE INVENTION

One embodiment of the present disclosure is an air duct assembly.

Another embodiment of the present disclosure, a refrigerator is also provided.

In this regard, according to an embodiment of the present disclosure, there is provided in the present disclosure an air duct assembly, 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.

According to the air duct assembly provided in the present disclosure, by arranging the air-uniformizing partition plate above the air inlet, the air entered from the air inlet on one side of the main body can be evenly divided to both sides of the air duct assembly by the air-uniformizing partition plate and the air is discharged via the air outlets. Due to an asymmetrical structure of the air duct, the inlet air is uniformly divided into the air outlets on both sides by providing the air-uniformizing partition plate. Generally, the air outlet communicates with an inner liner (refrigeration compartment) of the refrigerator, so that air volumes at the air inlets on both sides of the refrigeration compartment are evenly distributed, which reduces temperature differences among different parts, reduces the occurrence of temperature fluctuations, and effectively reduces the flow resistance loss and aerodynamic noise, realizing greater flow at the same fan rotating speed. A top end of the air-uniformizing partition plate may be a multi-section arc chamfer structure for further reducing aerodynamic resistance.

In addition, the air duct assembly in the above embodiment provided in the present disclosure may further have the following additional features:

In one embodiment, the plurality of air outlets comprises: a first air outlet, which is provided on a side of the main body closer to the air inlet; a second air outlet, which is provided at a top of the main body closer to the air inlet; a third air outlet, which is provided on a side of the main body farther from the air inlet; a fourth air outlet, which is provided at a top of the main body farther from the air inlet; and an deflecting plate, which is provided on the main body and located between the third air outlet and the air-uniformizing partition plate, and the deflecting plate divides the inlet air farther from the air inlet into the third air outlet and the fourth air outlet.
