And, the first wind deflector 22 can adjust the sweeping angle, sweeping direction, open or close, and the speed of sweeping of the first space of the air conditioner; Sweep angle, sweep direction, open or close, and sweep speed, etc.

More specifically, there are multiple first wind deflectors 22, and the multiple first wind deflectors 22 are horizontally connected; there are multiple second wind deflectors 42, and the multiple second wind deflectors 42 are horizontally connected;

In the specific implementation process, the first air deflector 22 is driven by the first motor, and the adjacent first air deflector 22 is linked by a connecting rod, and the two ends cooperate with the parts of the housing 1; the second air deflector 42 is driven by the second motor, and the adjacent second air deflectors 42 are linked by connecting rods, and the two ends are matched with the parts of the housing 1 .

Based on the fact that the first wind deflector 22 and the second wind deflector 42 in this embodiment are independent of each other, and the first fan 21 and the second fan 41 are independent of each other, the air conditioner provided in this embodiment has a variety of air supply modes, Assuming that the area where the first fan assembly 2 is located is the left area, and the area where the second fan assembly 4 is located is the right area, the air supply mode is specifically:

The first air supply mode: as shown in Figure 6, the first fan assembly 2 and the second fan assembly 4 sweep the wind alone, that is, when the sweeping directions of the first wind deflector 22 and the second wind deflector 42 are opposite, it can Realize partitional sweeping of the left and right areas. In this air supply mode, the first air deflector 22 and the second air deflector 42 can realize:

Simultaneous wind sweeping on the left and right sides (constant speed sweeping or differential speed sweeping);

Sweeping on one side and fixed air supply on one side, the angle of fixed air supply can be set independently;

Fixed-frame air supply on both sides, fixed-frame air supply angle can be set independently;

The second air supply mode: as shown in Figure 7, the first fan assembly 2 and the second fan assembly 4 sweep the wind synchronously, that is, when the sweeping directions of the first wind deflector 22 and the second wind deflector 42 are the same, the Air supply on the same side, in this air supply mode, the air deflectors on the left and right sides can realize:

Constant speed or differential sweep;

Sweeping on one side and fixed air supply on one side, the angle of fixed air supply can be set independently;

Fixed-frame air supply on both sides, fixed-frame air supply angle can be set independently;

Under the above two formulas, when the user needs to turn off the air conditioner, the angular positions or sweeping speeds of the first wind deflector 22 and the second wind deflector 42 at that time are inconsistent. In order to simplify the control logic when the wind deflector is closed, first Rotate the first wind deflector 22 and the second wind deflector 42 on the left and right sides to a default angle at the same speed (in this embodiment, the default angle is set to the center position angle), and then close at the same speed.

At the same time, in the scheme mentioned in this embodiment, the first blower fan 21 and the second blower fan 41 independently set the speed, that is, when the user needs to achieve different air supply intensities on both sides (for example, corresponding to low, medium and high windshields) , you can independently set the fan speed on both sides; this logic is applicable to any of the above-mentioned air supply modes.

In addition, as shown in Fig. 8 and Fig. 9, when the user only needs to have air flow from one side and no air flow from the other side, the fan and air deflector on one side can be turned off separately, and only the fan on one side and the air deflector can be turned on. Air deflector, in this mode, the air deflector can freeze or rotate to sweep the air. At the same time, in this mode, when the user shuts down the air conditioner, the air deflector can be closed from the current position without first turning it on. Close it after reaching the default angle. In order to simplify the overall control logic, the logic control of closing the wind deflector in this mode can be set with reference to the above-mentioned mode.

The air conditioner provided in this embodiment realizes the above-mentioned multi-air supply mode. Since the left and right sides are provided with separate evaporators, the size of the evaporator is smaller than that of the integrated evaporator. At the same time, for the evaporator on one side As far as the evaporator is concerned, the setting position of the fan assembly can realize the full coverage of the evaporator and the air intake area, which not only improves the utilization efficiency of the evaporator, but also improves the uniformity of the air intake in the air intake area, thereby improving the overall internal evaporator System utilization. In summary, those skilled in the art can easily understand that, on the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

The above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still belong to the technology of the present invention. within the scope of the program.
