According to the air conditioner control method, the matching mode of the main air duct 11 and the fresh air duct 21 matched with the air conditioner can be automatically adjusted according to the operation condition of the whole air conditioner.
In the first embodiment of the present invention, specifically, as shown in fig. 11, after the fresh air is turned on, when it is detected that the operation mode of the air conditioner is the cooling mode, the stepping motor of the driving mechanism operates the sliding plate 31 to the position 1, or when it is detected that the air conditioner operates for heating, the stepping motor of the driving mechanism operates the sliding plate 31 to the position 2, where the stepping motor of the driving mechanism is the first driving motor of the first driving assembly 32, the position 1 is a position where the sliding plate 31 completely blocks the communication opening 120 (i.e., a position where the communication opening 120 is closed), and the position 2 is a position where the sliding plate 31 opens the communication opening 120 (i.e., a position where the communication opening 120 is opened).
Then, when it is detected whether the air conditioner switches the operation mode, the sliding plate 31 is switched to another position when the air conditioner switches the operation mode, and if the operation mode is not switched, the position of the sliding plate 31 is maintained.

Specifically, as shown in fig. 1 and 2, when the operation mode of the air conditioner is the cooling mode, the default air outlet state of the air conditioner is the upper air outlet, the first driving motor adjusts the sliding plate 31 to the position completely blocking the communication opening 120, at this time, the sliding plate 31 closes the communication opening 120, the first air outlet 100 is divided into a fresh air outlet and a main air outlet by the sliding plate 31, and the fresh air duct 21 operates independently to introduce fresh air outdoors. At this moment, the temperature of the fed fresh air is higher than the indoor temperature, because the first air outlet 100 is located below the air conditioner complete machine, namely the fresh air outlet is also located below the air conditioner complete machine, the indoor air temperature is overall lower, and the fresh air volume is far lower than the air conditioner volume, the introduction of the fresh air has no great influence on the distribution of the indoor temperature, and meanwhile, the fresh air is independently discharged, so that the fresh air cannot leak into the refrigerated main air duct, dew is prevented from being generated in the air duct, the quality of the product is ensured, and the potential safety hazard is reduced.
Preferably, in the embodiment of the present invention, the air outlet direction of the fresh air duct 21 is upward air outlet, that is, after flowing out through the fresh air outlet, at least a part of the fresh air is mixed with the air flow flowing out of the main air duct 11, and the air flow flowing out of the main air duct 11 reduces the temperature of at least a part of the fresh air, so as to reduce the temperature difference between the fresh air temperature and the indoor temperature, and avoid the air duct from generating condensed water.
As shown in fig. 3 and 4, when the operation mode of the air conditioner is the heating mode, the default air-out state of the air conditioner is the lower air-out state, the first driving motor adjusts the sliding plate 31 to the position where the communication opening 120 is completely opened, the communication opening 120 is completely in the sliding groove 210 at this time, the communication opening 120 is in the open state, the fresh air flow in the fresh air duct 21 is mixed with the air flow in the main air duct 11 to be discharged, thus, the fresh air can be heated by the air flow in the main air duct 11, the temperature of the introduced fresh air is raised, the temperature difference between the fresh air temperature and the indoor temperature is reduced, condensation formed on the air conditioner panel due to the lower fresh air temperature is prevented, the quality of the product is ensured, the potential safety hazard is reduced, meanwhile, the fresh air is prevented from being blown to the user, and the comfort of the user is improved.
In the first embodiment of the present invention, the mechanism for realizing the air duct connection is the sliding plate 31 driven by the transmission gear 321 and the transmission rack 311, the transmission rack 311 and the sliding plate 31 are designed as a whole, the chute 210 is fixed in the fresh air duct 21, the operation position of the sliding plate 31 can be dynamically changed according to the operation mode of the air conditioner, and the sliding plate 31 slides along the extending direction of the chute 210, so the sliding plate 31 has no influence on the sweeping rotation of the sweeping blades of the first air outlet 100.
Preferably, the transmission gear 321 and the first driving motor are driven by a motor in a direct connection manner.
In a second embodiment of the present invention, as shown in fig. 6 to 9, the shutter assembly 30 includes: a rotation plate 33, the rotation plate 33 being rotatably provided at the communication opening 120 to open or close the communication opening 120.
Specifically, the shielding assembly 30 further includes: and the second driving motor 330, the second driving motor 330 is in driving connection with the rotating plate 33 to drive the rotating plate 33 to rotate.
When the air conditioner is in a refrigeration mode, the air conditioner is in an upper air outlet state at the moment by default, and the second driving motor 330 controls the rotating plate 33 to be in a position completely blocking the communicating opening 120, so that the fresh air duct 21 operates independently; when the air conditioner is in the mode of heating, the air conditioner is acquiescently in the air-out state down this moment, then second driving motor 330 control rotor plate 33 is in the position that intercommunication opening 120 was opened completely, makes new trend air current and main wind channel air current mix the heat transfer, and then realizes reducing new trend and indoor difference in temperature, prevents relevant spare part condensation problem. Since the rotating plate 33 is adjusted in position by rotating it up and down, the second embodiment affects the operation of the wind sweeping blades compared to the first embodiment.
Preferably, as shown in fig. 7, the rotating plate 33 and the second driving motor 330 are driven by a motor in a direct connection manner.
In the third embodiment of the present invention, as shown in fig. 10, the communication opening 120 between the fresh air duct 21 and the main air duct 11 is directly communicated without the shielding component 30, so that the fresh air duct 21 and the air flow in the main air duct 11 are mixed, and the temperature difference of the indoor air is reduced.
