Detailed Description
Fig. 1 is a schematic configuration diagram of an air volume distribution device 300 according to an embodiment of the present invention. As shown in fig. 1 and referring to fig. 2, an embodiment of the present invention provides an air volume distribution device 300 of an air supply system of a refrigerator. The air volume distribution device 300 may include a centrifugal wind wheel 40, an air volume adjusting member 50, and a position adjusting device 60.
The air quantity adjusting member 50 may have an adjusting plate 51, a first baffle 52 and at least one first blowing port provided at one side of the adjusting plate 51, and a second baffle 53 and at least one second blowing port provided at the other side of the adjusting plate 51. Preferably, the first and second shutters 52 and 53 are disposed perpendicular to the adjustment plate 51. The adjusting plate 51 has a central through hole coaxially provided with the centrifugal wind wheel 40, and the centrifugal wind wheel 40 is mounted in the central through hole. The difference between the radius of the central through hole of the adjusting plate 51 and the radius of the centrifugal wind wheel 40 is 3mm to 15 mm. The at least one first air supply outlet and the at least one second air supply outlet are arranged in a staggered mode. And also

When the air distribution device 300 is used, the air output on two sides of the adjusting plate 51 can be changed by adjusting the position of the adjusting plate 51, the structure is simple, the air distribution can be freely adjusted, the adjustment is convenient, and the air distribution is more accurate. The centrifugal fan adopts a cone structure and does not have a complex air duct. The first air supply outlet and the second air supply outlet are arranged in a staggered manner, so that when the adjusting plate 51 moves, the first baffle plate 52 can automatically shield a part of the connecting air opening aligned with the second air supply outlet, so as to prevent the airflow on the side of the first baffle plate 52 from entering the connecting air opening; likewise, the second shutter 53 can automatically block a portion of the connection tuyere aligned with the first blowing port to prevent the air flow of the second shutter 53 side from entering the connection tuyere.
Further, the air quantity is adjusted through the adjusting plate 51, interference between air flows on two sides of the adjusting plate 51 is small, and air quantity adjustment is more accurate. Compared with the prior centrifugal fan in which the air outlet is provided with the movable baffle to realize air volume distribution, the air outlet direction is selected to generate air flow turbulence when all air flows reach the edge of the air inlet side of the baffle, the noise is high, and the air flows reaching the edge of the air inlet side of the baffle are various (various in direction and speed) and not particularly stable due to various reasons during air supply of the fan, so that the turbulence can be generated, and the noise and the accuracy of air volume distribution are influenced.
In some embodiments of the present invention, the first baffle 52 and the second baffle 53 may each be cylindrical. The first and second blowing ports may be opened on the first and second shutters 52 and 53, respectively. In other embodiments of the present invention, each of the first and second shutters 52 and 53 may include a plurality of sub-shutters, and an interval between each two sub-shutters may be the first supply port or the second supply port. For example, the first and second air blowing ports are both one. And a gap between two edges of the first barrier 52 extending in parallel to the axial direction of the centrifugal wind wheel 40 is a first air blowing port.

The length of the first barrier 52 may be 3 to 10 times the length of the second barrier 53. The positions of the first shutter 52 and the second shutter 53 with respect to the adjustment plate 51 are interchangeable, as shown in fig. 1 and 2.
In some embodiments of the present invention, the position adjustment device 60 may include a sleeve 61, a moving member, and a support plate 63.

For example, the moving member may include two guide blocks. The support plate 63 is mounted on the moving member and moves along the axial direction of the centrifugal wind wheel 40 along with the moving member; and the air volume adjusting member 50 is connected to the support plate 63. Specifically, it may be connected by a plurality of support columns 64 provided between the support plate 63 and the adjustment plate 51.
Further, the air distribution device 300 may further include a motor disposed in the sleeve 61 and driving the centrifugal wind wheel 40 to rotate. Further, the air volume distribution device 300 may further include a transmission mechanism connecting the motor and the sleeve 61 to intermittently transmit the rotational movement of the motor to the sleeve 61. In some alternative embodiments, another motor may be included for driving the sleeve 61 to rotate.
As shown in fig. 3 to 6, an embodiment of the present invention further provides a refrigerator. A refrigerator may generally include a cabinet 100 and a door. The cabinet 100 has a duct assembly 200, a storage compartment, a cooling compartment, and a refrigeration system therein.

Specifically, the air duct assembly 200 further has the air volume distribution device 300 in any of the above embodiments, the air volume distribution device 300 is installed in the accommodating cavity 210, and each first air supply outlet and each second air supply outlet are communicated with at least one air supply duct 220. When the centrifugal wind wheel 40 is used, cold wind is absorbed from the cooling chamber, and air flow is conveyed into the storage chamber through the at least two air supply air ducts 220. Preferably, the rear side of the wind tunnel assembly 200 is a cooling chamber in the box 100, and the receiving cavity 210 is opened rearward so that the centrifugal wind wheel 40 sucks in an air flow from the cooling chamber. Each of the air supply ducts 220 may extend in the up-down direction. The structure is more compliant with the air flow direction of the fan.
In some embodiments of the invention, the storage compartment comprises a first storage compartment and a second storage compartment.

For example, the first storage compartment may be a freezer compartment. The second storage compartment can be a refrigerating chamber and is arranged on the upper side of the freezing chamber. Furthermore, a temperature-changing chamber can be arranged between the first storage chamber and the second storage chamber.
Further, the first air supply outlet is one. The first air supply outlet is communicated with the first storage compartment through two air supply ducts 220, and the two air supply ducts 220 are a first air supply duct 221 and a second air supply duct 222. The front surface of the air duct assembly 200 is also provided with a first vertical air supply outlet and a second vertical air supply outlet; the first vertical air supply outlet is communicated with a first air supply duct 221, and the second vertical air supply outlet is communicated with a second air supply duct 222.

The rear side of the second storage compartment may be provided with an air duct structure communicated with the third air supply duct 223. Accordingly, the variable temperature chamber may also be provided with a duct structure communicating with the third supply air duct 223.
The air distribution device 300 of the air supply system of the refrigerator and the refrigerator with the same have simple structure, can realize free adjustment of air distribution, are convenient to adjust and are more accurate in air distribution because of the adjusting plate 51, the first baffle plate 52 and the second baffle plate 53.
