Thus, the operation method of the air conditioner 100 can be made simpler, and the control efficiency of the air conditioner 100 can be improved.

Optionally, in the air flow direction, the second fan 212 is located downstream of the first fan 211, and the first fan 211 is controlled to stop rotating at each level of windlessness from the first gear to the M-th gear. Among the M gears from the first gear to the M-th gear, the higher the gear, the higher the rotation speed of the second fan 212, and M<N. Specifically, when the air conditioner 100 is in the windless mode, if the windlessness level of the air conditioner 100 is between the first gear and the Mth gear, the first fan 211 does not output the rotation speed. If the windlessness level needs to be adjusted, the rotation speed of the second fan 212 and/or the lower fan assembly 211 can be adjusted to switch the windlessness level from the first gear to the Mth gear.

For example, the plurality of windlessness levels may include the first gear to the eighth gear. If the windlessness level of the air conditioner 100 is between the first gear and the fourth gear, the first fan 211 does not output the rotation speed. When the air conditioner 100 is adjusted between the first gear and the fourth gear, only the output speed of the second fan 212 may be adjusted. Among the four gears from the first gear to the fourth gear, the higher the gear without wind feeling, the higher the rotation speed of the second fan 212. Therefore, through the above arrangement, the control method of the air conditioner 100 can be simplified, and the control efficiency of the air conditioner 100 can be improved.

Further, in each gear from the M+1th gear to the Nth gear, the first fan 211 is controlled to rotate. For example, in each gear from the M+1th gear to the Nth gear, the first fan 211 may be maintained at a fixed output speed, or the output speed of the first fan 211 may be gradually increased. Thus, with the above arrangement, the operation method of the air conditioner 100 can be made simpler.

Furthermore, in each gear from the M+1th gear to the Nth gear, the rotation speed of the second fan 212 is greater than the rotation speed of the first fan 211. It can be understood that, in the multiple gears from the M+1th gear to the Nth gear, the first fan 211 and the second fan 212 rotate at the same time and blow air toward the first air outlet 1a at the same time. As shown in FIG. 5, the second fan 212 may be located on the front side of the first fan 211. By setting the rotation speed of the second fan 212 to be greater than the rotation speed of the first fan 211, the second fan 212 can apply driving force to the first fan 211. Therefore, the wind loss of the upper fan assembly 21 can be reduced, and the air blowing effect of the upper fan assembly 21 can be improved. Of course, it can be understood that, in each gear from the M+1th gear to the Nth gear, the output speed of the first fan 211 and the second fan 212 may also be the same.

Specifically, among the multiple gears from the M+1th gear to the Nth gear, the higher the gear, the higher the rotation speed of the second fan 212. Thus, as the level of windlessness increases, the second fan 212 can cooperate with the first fan 211 by increasing the output speed to achieve a longer air supply distance. For example, as shown in FIG. 5, the upper fan assembly 21 is located above the lower fan assembly 22. Among the multiple gear positions from the M+1th gear to the Nth gear, the air supply distance of the upper fan assembly 21 may be greater than that of the lower fan For the air supply distance of the component 22, the air flow located above can circulate slowly from top to bottom in the indoor space, thereby making the indoor temperature distribution more uniform. Moreover, the air flow located below can circulate slowly from bottom to top and can be mixed with the air flow above, which can play a role of mixed flow, which can make the indoor temperature distribution more uniform, and can improve the cooling and heating of the air conditioner effect.

In a specific example of the present application, the air conditioner 100 may include a cabinet 1, a fan part 2, an air outlet frame part 3 and a heat exchanger part 4. Among them, the fan component 2, the air outlet frame component 3 and the heat exchanger component 4 can all be arranged in the casing 1. The casing 1 may include a panel part 11 and a back plate part 12. The panel part 11 is arranged on the front side of the back plate part 12 and cooperates with the back plate part 12 to define a visible area 1d. The first air outlet 1a and the second air outlet 1b are spaced apart, and the backboard member 12 is provided with an air inlet 1c.

The fan component 2 includes an upper fan assembly 21, a lower fan assembly 22, and an air duct mounting plate 23. The upper fan assembly 21 and the lower fan assembly 22 are both arranged on the air duct mounting plate 23 and spaced in the vertical direction. The upper fan assembly 21 can Air is blown toward the first air outlet 1a, and the lower fan assembly 22 can blow air toward the second air outlet 1b. Wherein, the upper fan assembly 21 includes a first fan 211 and a second fan 212 arranged in the front-rear direction, and the second fan 212 is located on the front side of the first fan 211. The lower fan assembly 22 includes a third fan 221 located below the upper fan assembly 21. In the direction of air flow, the air outlet frame part 3 is located downstream of the fan part 2, and the air outlet frame part 3 is provided with a first air outlet frame 31 that is arranged directly opposite to the upper fan assembly 21 and is directly opposite to the lower fan assembly 22. With respect to the second air outlet frame 32 provided, the first air outlet frame 31 is arranged directly opposite to the first air outlet 1a, and the second air outlet frame 32 is arranged directly opposite to the second air outlet 1b. Wherein, at least a part of the air outlet frame member 3 can be seen through the visible area 1d, so that the air conditioner 100 can be decorated.

Optionally, the upper fan assembly 21 may be a counter-rotating fan, which not only makes the overall structure of the air duct component more compact, but also achieves a better air supply effect. Further, when the rotation speed of one of the first fan 211 and the second fan 212 is adjusted, the rotation speed of the other fan can be automatically adjusted. Of course, the speeds of the first fan 211, the second fan 212, and the third fan can be adjusted independently, and the adjustment is frequency hopping adjustment.

Specifically, the third fan 221 in the lower fan assembly 22 is an axial fan.

In some embodiments of the present application, the difference between the windless distances of two adjacent gears may not exceed 0.5 m, so that the position of the windless area can be accurately controlled, and the windless effect of the air conditioner 100 can be improved. It is understandable that if the windless distance between two adjacent gears is relatively large, the windless area cannot cover the entire indoor space, thereby affecting the comfort of the user. By setting the difference of the windless distance between the two gears to no more than 0.5m, and by selecting different gears so that the windless area covers every position in the indoor space, the user's needs can be met. Optionally, the difference between the windless distances of two adjacent gears may be 0.3 m.

For example, in a specific example of the present application, multiple levels of windlessness may include the first to sixth gears, the windless distance of the first gear is 0.5m-1m, and the windless distance of the second gear is 1m-1.5m, the windless distance of the third gear is 1.5m-2m, the windless distance of the fourth gear is 2.5m-3m, the windless distance of the fifth gear is 3.5m-4m, and the sixth gear The windless distance is 4.5m-5m.

According to some embodiments of the present application, when the air conditioner 100 is controlled to switch to the windless mode, the operating frequency of the compressor can be reduced to the first set frequency. It can be understood that when the air conditioner 100 is in the full-house cool feeling mode or the super-distant air supply mode, the operating frequency of the compressor is different compared with the no wind feeling mode. Since the air supply speed of the windless mode is relatively slow, the required operating frequency of the compressor is relatively small. By reducing the operating frequency of the compressor, the energy consumption of the air conditioner 100 can be reduced, and the service life of the compressor can be prolonged. For example, when controlling the air conditioner 100 to switch to a windless mode, the operating frequency of the compressor can be reduced to 35W.

In some embodiments of the present application, after the operating frequency of the compressor is set to the set frequency, the indoor ambient temperature can be detected, and the indoor ambient temperature and the set temperature can be compared to obtain the temperature difference. When the temperature difference is greater than the first set Value, the operating frequency of the compressor can be increased. When the temperature difference is less than the first set value, the operating frequency of the compressor can be reduced. This not only ensures the cooling and heating efficiency of the air conditioner 100, but also reduces the air conditioner 100’s operating frequency. energy consumption.

For example, after setting the operating frequency of the compressor to the set frequency, if the temperature difference between the detected indoor ambient temperature and the set temperature corresponding to the current gear is greater than or equal to 8°C, the operating frequency of the compressor is increased To 40W. If the temperature difference between the indoor ambient temperature and the set temperature corresponding to the current gear is less than 8°C, reduce the operating frequency of the compressor to 25W.
