In some further aspects of the present invention, the number of air outlets may be referred to, and the air outlets may be sequentially arranged in the circumferential direction of the base 110 at intervals. The first flow guide plate 410 and the second air outlet 122 and the third air outlet 122, respectively Flow guiding plate 420. In particular, both the first flow guide plate 410 and the second flow guide plate 420 are long plates. The first flowguiding plate 410, and the second flowguiding plate 420, is shown as being the first flowguiding plate 410, and extends to the side, far away from the centrifugal impeller, of the inside of the housing 100 to flow out of the air-feeding device 300 to and from the air-feeding device. Through the three air outlets and the flow gathering plate 500, the second air outlet 122 and the third air outlet 23 may be defined as 65%: 25%: 10%, accurately quantifying refrigeration air supply amount of the storage compartments or different storage spaces of each storage compartment.

The first circulation part 211 is provided with the circulation passageway 110 at intervals; The two circulation holes in the second circulation part 212 are each completely different from each other.

As shown in Figs. 6-13 , when the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 6 , the three circulation holes in the second circulation part 212 allow the first, second and third air outlets 121, 122 and 123 to be in an open state. When the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 7 , the second baffle plate 221 may completely shield the second and third air outlets 122 and 123, and the circulation hole in the second circulation part 212 allows the second air outlet to be fully exposed. When the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 8 , the first baffle plate 221 may completely shield the third air outlet 123, the second baffle plate 222 may completely shield the first air outlet 121, and the circulation hole 211 allows the second air outlet 122 to be fully exposed.

When the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 10 , the second baffle plate 222 allows the first and second circulation holes 212 and 122 to be fully exposed. When the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 11 , the first baffle plate 221 only allows the second and third circulation holes 122 and 123 to be fully exposed. When the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 12 , the first baffle plate 221 may completely shield the second air outlet 122, allows the circulation in the first circulation part 212 allows the third air outlet 123 to be fully exposed. When the first baffle plate 221 and the second baffle plate 222 are rotated to the position shown in Fig. 13 , the second baffle plate 222 may completely shield the first, second and third air outlets 121, 122 and 123. Of course, the first baffle plate 221 and the second baffle plate 222 may also be rotated to other rotational positions to regulate the air path and the air supply amount.

Baffle plates 220. If only one baffle plate 220 is included, both sides of the baffle plate allow air to pass. If the regulating component 200 comprises a baffle plate 220, a gap between every two baffles 220 allows air to pass.

Specifically, in this embodiment, the number of the air outlets may be three and the air outlets are sequentially arranged in the circumferential direction of the base 110 at intervals. The three air outlets 121, the second air outlet 122 and the third air outlet 122 counterclockwise arranged along the circumferential direction of the base 110 at intervals sequentially. The number of baffle plates 220 is two. The two baffle plates 220 include a first baffle plate 221 and a second baffle plate 222 which are counterclockwise arranged in the circumferential direction of the base. The first baffle plate 221 is designed to completely shield one air outlet. The first baffle plate 222 is configured to complete shield two air outlets. A gap between the first baffle plate 221 and the second baffle plate 222 is configured to complete shield one air outlet. When neither the first baffle plate 221 nor the second baffle plate 222 the first, second and third air outlets 121, 122 and 123 are in the open state. When the second baffle plate 222 completely shields the second and third air outlets 122 and 123, a gap between the two baffle plates 220 allows the first air outlet 121 to be fully exposed. When the first baffle plate 221 completely shields the first air outlet 121, the second baffle plate 222 allows the second air outlet 122 to be fully exposed. When the second baffle plate 222 completely shields the first and second air outlets 121 and 122, the third air outlet 123 is fully exposed. When the first baffle plate 221 is completely exposed, the first and second air outlets 121 and 122 are fully exposed. When the second baffle plate 222 is completely exposed, the second and third air outlets 122 and 123 are fully exposed. When the first baffle plate 221 completely shields the second air outlet 122, the first air outlet 121 is fully exposed and has a gap between the two baffle plates 220.

In combination with Fig. 2 A gear ring 230 is arranged on the governing component 200 which seeks to regulate the rotation of the gear 620. The driving device is simple and compact in structure, and can be widely used Applied.

In particular, the water outlet 127 is formed in the inner side of the flow gathering plate 500. A small amount of water vapor enters the air passage along with the refrigeration air due to the incomplete sealing of the air passageway of the branching air supply device 10 and the refrigerator 1, resulting in The water vapor is deposited on the inner wall along with the rotation of a fan then the deposited water flows out of the water outlet 127;

In some of the present invention, when the baffle plates 125 are in the baffle plates alternative aspect, in order to facilitate the rotation of the component 200, a distance between each of the baffle plates 220 and the first circumferential wall section 125 can be slightly increased; however, the baffle plates 220 and the first circumferential wall section 125 are elevated, the air leakage occurs, it results in an incomplete and useless shielding effect. Thus, the branching air supply from each to another air outlet via a gap between the outer surface of each baffle plate 220 and the 125. In particular, the sealing device may include at least two sealing gaskets, each of which extends in a direction parallel to the rotating axis of the regulating component 200. A sealing gasket is arranged at each of the two ends of the arcuate outer surface of each baffle plate 220 along its rotating direction. In the case of the governing component 200, the baffle plates 220 and the circulation parts 210, the sealing device may further comprise different gaskets 210.
