[0068] Currently, the air outlet movement mechanism of existing air supply devices usually adopts a connecting rod - air deflector mechanism. The first air deflector is driven by a motor to rotate, and the first air deflector drives the connecting rod, which in turn drives other air deflectors to move. When this mechanism is installed at the air outlet of the air supply device, it will block part of the air outlet area and affect the air volume of the air outlet. In an embodiment of the present invention, a wind control mechanism is provided. The wind control mechanism consists of two air deflectors, namely a first air deflector and a second air deflector. By controlling and adjusting the angles of the two air deflectors, the size of the air outlet is adjusted to achieve air volume adjustment.

[0069] The following will Figure 1 - will Figure 12 elaborate in detail on the technical solutions of this embodiment. Without conflict, the following embodiments and examples can be combined with each other.

[0070] Embodiment

[0071] As Figures 1 - 12 shown, in the first aspect of this embodiment, a wind control mechanism is proposed for installation at the air outlet of an air supply device. The wind control mechanism 2 includes:

[0072] A first air deflector 21, which is rotatably arranged at the air outlet for opening or closing the air outlet. The first air deflector 21 has a first windward surface.

[0073] A second air deflector 22, which is rotatably arranged on the first windward surface of the first air deflector 21, and the second air deflector 22 has a second windward surface.

[0074] When the air outlet is opened through the first air deflector 21, the second air deflector 22 can be controlled to rotate to direct the airflow flowing out from the air outlet through the second windward surface.

[0075] Specifically, when the air control mechanism 2 is installed on the air supply device, rotating shafts and screw columns are designed at both ends of the first air deflector 21. The rotating shaft is in shaft-hole fit with the corresponding hole on the air inlet component 1a of the air supply device, and the screw column at the other end is fixedly fitted with the column on the gear transmission structure 26 in the first driving assembly, so as to drive the first air deflector 21 to rotate when the gear transmission structure 26 rotates. Rotating shafts are provided at both ends of the second air deflector 22. One of the rotating shafts is in fit with the hole on the first air deflector 21, and the other rotating shaft is in fit with the shaft of the second motor 27, and the second air deflector 2 is driven to rotate by the second motor 27.

[0076] In the embodiment of the present invention, by controlling the opening angle of the first air deflector 21, the size of the air outlet is adjusted to realize the adjustment of the air volume. By adjusting the angle of the second air deflector 22, the air outlet direction is adjusted. When supplying air, the second air deflector 22 can be driven to swing up and down to realize the air blown out from the air outlet to sweep in the up and down directions.

[0077] Further, as Figures 1 - 3 shown, the second air deflector 22 further has a second leeward surface opposite to the second windward surface, and the second leeward surface is arranged parallel to the second windward surface;

[0078] When the second air deflector 22 is driven to rotate, the second leeward surface can be rotated to be parallel to the first windward surface of the first air deflector 21.

[0079] That is, the second air deflector 22 in the embodiment of the present invention can be folded on the first air deflector 21, so as to realize the combination of the two air deflectors into one.

[0080] It should be noted that when the second air deflector 22 is folded on the first air deflector 21, the position where the second air deflector 22 is located at this time is the initial position of the second air deflector 22.

[0081] In any of the above embodiments, as Figures 1 - 3 shown, the first air deflector 21 has opposite first end 21a and second end 21b;

[0082] The first air deflector 21 is rotationally fitted with the air outlet at the position of the first end 21a, and the second air deflector 22 is rotationally fitted with the first air deflector 21 at the position of the second end 21b.

[0083] In the embodiment of the present invention, by setting the rotation positions of the first air deflector 21 and the second air deflector 22 to be relative and spaced apart by a certain distance, the sweeping effect of the second air deflector 22 can be improved.

[0084] In any of the above embodiments, as Figures 1 - 3As shown in the figure, on the first wind guiding plate surface of the first wind guiding plate 21, side wind guiding plates 23 are symmetrically convexly provided. A diversion air duct 3 is formed between the symmetrically arranged side wind guiding plates 23 and the first wind guiding plate surface of the first wind guiding plate 21. The diversion air duct 3 is used to converge the air flow flowing out from the air outlet.

[0085] In the embodiment of the present invention, by providing symmetric side wind guiding plates 23 on the first wind guiding plate 21, the air flow blown out from the air outlet is prevented from freely diffusing, so that the air blown out from the air outlet is gathered and blown out, improving the air outlet effect of the air outlet.

[0086] In any of the above embodiments, as Figures 1 - 3 shown, the side wind guiding plate 23 has a first side edge 231 near the rotation position of the first wind guiding plate 21 and a second side edge 232 opposite to the first side edge 231;

[0087] Among them, the protruding height of the first side edge 231 is greater than the protruding height of the second side edge 232, so as to define a gradually shrinking diversion air duct 3.

[0088] In the embodiment of the present invention, by setting the height of the first side edge 231 of the side wind guiding plate 23 to be greater than the height of the second side edge 232, the diversion air duct can be constructed into a gradually shrinking shape, thereby improving the air outlet effect of the air outlet.

[0089] In any of the above embodiments, as Figures 1 - 3 shown, the first wind guiding plate 21 further has a third section 21c and a fourth end 21d that are oppositely arranged between the first end 21a and the second end 21b. The first end 21a, the third section 21c, the second end 21b, and the fourth end 21d are sequentially connected to form the outer peripheral contour of the first wind guiding plate 21;

[0090] One of the side wind guiding plates 23 is arranged close to the third end 21c of the first wind guiding plate, and the other side wind guiding plate 23 is arranged close to the fourth end 21d of the first wind guiding plate.

[0091] In any of the above embodiments, as Figures 10 - 12 shown, the air control mechanism 2 further includes a driving assembly:

[0092] The driving assembly includes a first driving assembly and a second driving assembly. The first driving assembly is used to drive the first wind guiding plate 21 to rotate, and the second driving assembly is used to drive the second wind guiding plate 22 to rotate;

[0093] The first driving assembly includes a driving box 24 installed at the air outlet, a first motor 25 and a gear transmission structure 26 provided on the driving box 24. The first motor 25 drives the gear transmission structure 26 to rotate, and the gear transmission structure 26 drives the first wind guiding plate 21 to rotate. When the gear transmission structure 26 is driven to rotate, it can cooperate with the slide rail 200 on the air supply device, and the driving box 24 can cover the slide rail 200 on the air supply device;

[0094] The second driving component includes a second motor 27 installed on the first air deflector 21, and the second motor 27 drives the second air deflector 22 to rotate.

[0095] Specifically, as Figure 10 and Figure 11 shown, one end of the gear transmission structure 26 is fitted with a hole on the air inlet component, and the other end is fitted with the rotating shaft of the first motor 25. One end of the rotation center of the gear transmission structure 26 is fixed to the screw post on the first air deflector 21, and the other end is in shaft hole fit with the positioning post on the driving box 24. On the one hand, the driving box 24 is provided with a structure for installing the first motor. On the other hand, since a slide rail is provided on the air inlet component 1a when the gear transmission mechanism 26 rotates, the air blown out from the air outlet will leak from the slide rail. Therefore, the driving box 24 can seal this to prevent air leakage.

[0096] In the second aspect of the embodiment of the present invention, a air supply device is further provided. As Figures 1 - 12 shown, the air supply device includes a machine body 1, and a first ventilation opening 11 and a second ventilation opening 12 adjacent to the machine body 1. A air control mechanism according to any one of claims 1-7 is provided at the first ventilation opening 11;

[0097] The first ventilation opening 11 can be controlled to intake air or exhaust air, and the second ventilation opening 12 is used for intake air;

[0098] Among them, the first ventilation opening 11 has a second end disposed close to the second ventilation opening 12, and the first air deflector 21 in the air control mechanism is rotatably disposed at the second end position of the first ventilation opening 11.

[0099] In the embodiment of the present invention, by rotatably disposing the first air deflector 21 at the second end position of the first ventilation opening 11, when the first ventilation opening 11 exhausts air {the first air deflector 21 opens}, and when the second ventilation opening 12 intakes air, the opened first air deflector 21 can isolate the first ventilation opening 11 and the second ventilation opening 21, thereby avoiding the mixing of the intake air flow and the exhaust air flow and affecting the air supply effect of the air supply device.

[0100] Furthermore, the air supply device is a cabinet air conditioner;

[0101] The first ventilation opening 11 and the second ventilation opening 12 are disposed at the top of the machine body 1, and a third air outlet 13 and a fourth air outlet 14 are provided at the bottom of the machine body 1;

The top position of the fuselage housing channel 5 is connected to the second ventilation opening 12, and the bottom position is connected to the fourth air vent 14;

The upper centrifugal fan system 8 is arranged in the upper air outlet duct 41, and the lower centrifugal fan system 9 is arranged in the lower air outlet duct 42. The middle position of the fuselage housing channel 5 is connected to the upper centrifugal fan system 8 and the lower centrifugal fan system 9;

[0105] An upper return air opening 411 communicating with the fuselage housing channel 5 and the upper air outlet duct 41 is opened on the side wall of the upper air outlet duct 41. An upper baffle 412 is rotatably arranged at the position of the upper return air opening 411. The upper baffle 412 is used to open the upper return air opening 411 while closing the lower end of the upper air duct or closing the upper return air opening 411 while opening the lower end of the upper air duct. A lower return air opening 421 communicating with the fuselage housing channel 5 and the lower air outlet duct 42 is opened on the side wall of the lower air outlet duct 42. A lower baffle 422 is rotatably arranged at the position of the lower return air opening 421. The lower baffle 422 is used to open the lower return air opening 421 while closing the upper end of the lower air duct or closing the lower return air opening 421 while opening the upper end of the lower air duct.

[0106] By providing an upper return air opening 411 and a lower return air opening 421 that can be opened or closed on the side walls of the upper air outlet duct 41 and the lower air outlet duct 42 in the cabinet air conditioner according to the embodiment of the present invention, the air conditioner in the embodiment of the present invention can have multiple air outlet modes.

[0107] Specifically, the air conditioner in the embodiment of the present invention has a single upper air outlet cooling mode and a single lower air outlet heating mode.

[0108] As Figure 8 shown, when the air conditioner operates in the single upper air outlet cooling mode, the upper baffle 412 is controlled to rotate to close the upper return air opening 411, the lower baffle 422 is controlled to rotate to open the lower return air opening 421, the upper centrifugal fan system 8 is started, the lower centrifugal fan system 9 is closed, the first air deflector 21 is controlled to rotate to open the first ventilation opening 11, and the second air deflector is controlled to rotate reciprocally;

[0109] Specifically:

[0110] When the air conditioner operates in the single upper air outlet cooling mode, as Figure 8As shown in the figure, the upper baffle 412 is driven to rotate to close the upper air return opening 411, the lower baffle 422 is driven to rotate to open the lower air return opening 421, the upper air outlet duct 41 is opened, the lower air outlet duct 42 is closed, the third air outlet 13 is converted into an air inlet, the third air outlet 13 is communicated with the lower air return opening 421 through the lower channel 7, the upper centrifugal fan system 8 is started, the lower centrifugal fan system 9 stops running, the first air deflector 21 is controlled to rotate to open the first ventilation opening 11, the second air deflector is controlled to rotate reciprocally. At this time, a part of the indoor air enters the fuselage shell channel 5 from the third air outlet 13 at the bottom of the fuselage 1 through the lower channel 7 and the lower air return opening 421, and another part of the indoor air enters the fuselage shell channel 5 from the second ventilation opening 12 at the top of the fuselage 1 and the fourth air outlet 14 at the bottom of the fuselage 1, and is blown out from the first ventilation opening 11 at the top of the fuselage 1 under the action of the upper centrifugal fan system 8.

[0111] At this time, the reciprocating rotation of the second air deflector 21 realizes the air sweeping of the air blown out from the first ventilation opening 11 in the up and down directions, and the first air deflector 21 adjusts the angle of the upper air outlet to realize the air volume of different gears of the air outlet;

[0112] As Figure 9 shown in the figure, when the air conditioner operates in the single lower air outlet heating mode, the upper baffle 412 is controlled to rotate to open the upper air return opening 411, the lower baffle 422 is controlled to rotate to close the lower air return opening 421, the upper centrifugal fan system 8 is closed, the lower centrifugal fan system 9 is started, the first air deflector 21 is controlled to rotate to open the first ventilation opening 11, and the second air deflector is driven to rotate to be parallel to the first air deflector.
