In order to realize the control of the air-cooled refrigerator with three compartments, referring to fig. 4, the step 43 may specifically include:
431. when the operation state required by the air-cooled refrigerator is a first operation state, controlling the driving structure to drive the air distribution plate to move to a first preset position, and enabling the first compartment of the air-cooled refrigerator, the second compartment of the air-cooled refrigerator and the third compartment of the air-cooled refrigerator to be supplied with air; the air-cooled refrigerator enters a first operating state.
Specifically, referring to fig. 5, in the first operation state, wind enters all the three chambers, and when the air distribution plate 4 includes three air distribution pieces, the air distribution plate 4 needs to be moved to prevent the three air distribution pieces from blocking the air inlet 8, so that the wind sucked by the centrifugal fan 7 can enter the three chambers through the air distribution of the air duct air distribution assembly 6.
432. When the operation state required by the air-cooled refrigerator is a second operation state, controlling the driving structure to drive the air distribution plate to move to a second preset position, so that the first compartment of the air-cooled refrigerator and the second compartment of the air-cooled refrigerator enter with wind, and the third compartment of the air-cooled refrigerator enters without wind; the air-cooled refrigerator enters a second operating state.
Specifically, referring to fig. 6, in the second operating state, when wind enters the first compartment and the second compartment, and no wind enters the third compartment, and the air distribution plate 4 includes three air distribution pieces, the air distribution plate 4 needs to be moved to make the first air distribution piece 401 block the air inlet 8, so that the wind sucked by the centrifugal fan 7 can enter the first compartment and the second compartment through the split flow of the air duct air distribution assembly 6.
433. When the running state required by the air-cooled refrigerator is a third running state, controlling the driving structure to drive the air distribution plate to move to a third preset position, so that wind enters a second chamber of the air-cooled refrigerator and a third chamber of the air-cooled refrigerator, and no wind enters a first chamber of the air-cooled refrigerator; and the air-cooled refrigerator enters a third running state.
Specifically, referring to fig. 7, in the third operating state, when wind enters the second compartment and the third compartment, and no wind enters the first compartment, and the air distribution plate 4 includes three air distribution pieces, the air distribution plate 4 needs to be moved to make the second air distribution piece 402 block the air inlet 8, so that the wind sucked by the centrifugal fan 7 can enter the second compartment and the third compartment through the split flow of the air duct air distribution assembly 6.

In addition, because of the structure of the centrifugal fan, the air sucked by the centrifugal fan is not in the direction perpendicular to the suction direction when being discharged, but can deflect at a small angle along the rotating direction of the fan blades of the centrifugal fan, so that the unique air distribution piece shapes in the figures 5 to 8 and the blocking positions of the air distribution pieces in different running states can furthest ensure that the air sucked by the centrifugal fan is blown into a required compartment; further referring to fig. 9, taking the air-cooled refrigerator in the fourth operating state as an example, when there is a gap (a portion shown by a dotted line in fig. 9) between the downstream side of the third air splitter 403 and the corresponding second compartment of the air inlet 8 due to a process error, the air sucked by the centrifugal fan 7 is sucked from the direction perpendicular to the paper surface toward the inside, but when being discharged to the air duct formed by the air duct splitter assembly 6, the air is deflected according to the direction of rotation of the fan blades of the centrifugal fan 7, so that the air enters the air duct opening of the first compartment adjacent to the second compartment due to the deflection effect, and does not or only slightly enters the second compartment through the gap when being blown out by the centrifugal fan, which can meet the requirement that the air-cooled refrigerator in fig. 9 enters the fourth operating state; therefore, in the actual design, the first angle and the second angle are not specifically limited, as long as the requirement that the air-cooled refrigerator enters the corresponding operation state is met. Still further, the shape of the air distribution piece provided in the embodiment of the present invention is also an optimal condition, and in an actual design, the shape of the air distribution piece can be designed according to the air channel condition formed by the air channel air distribution component in the air distribution device of the air-cooled refrigerator and the deflection condition of the centrifugal fan.
The embodiment of the invention provides a control method of an air distribution device of an air-cooled refrigerator, which comprises the following steps: the air duct cover plate, the air duct bottom plate, the fixed guide rail, the air distribution plate and the driving structure are arranged on the air duct; wherein, the air duct bottom plate and the air duct cover plate are in parallel relation; an air duct air distributing assembly and a centrifugal fan are arranged between the air duct bottom plate and the air duct cover plate; cold air sucked by the centrifugal fan is conveyed into each chamber through the air duct air distribution assembly; an air inlet is formed in the position, opposite to the centrifugal fan, on one side, close to the air channel bottom plate, of the air channel cover plate; the fixed guide rail is arranged on one side of the air duct cover plate, which is far away from the air duct bottom plate, and the air distribution plate is arranged on the fixed guide rail; the driving structure is arranged on one side, far away from the air channel bottom plate, of the air channel cover plate and used for driving the air distribution plate to move along the fixed guide rail to shield the air inlet so as to control the air inlet position of the air inlet. Therefore, when the air distribution device of the air-cooled refrigerator provided by the embodiment of the invention is controlled, the compartment parameters of each compartment of the air-cooled refrigerator can be obtained firstly, then the running state required by the air-cooled refrigerator is judged according to the compartment parameters of each compartment of the air-cooled refrigerator, and then the driving structure is controlled to control the movement of the air distribution plate according to the running state required by the air-cooled refrigerator, so that the air inlet position of the air inlet can be changed until the air-cooled refrigerator enters the required running state; when the air inlet position of the air is changed, the air sucked from the air inlet by the centrifugal fan enters the corresponding compartment through the air channel formed by the corresponding air channel air distributing assembly according to the air inlet position to refrigerate the compartment, so that the air-cooled refrigerator enters the required running state.
