Specifically, the air-conditioning indoor unit is the air-conditioning indoor unit provided above; after the first air deflector 20 is controlled to move towards the direction far away from the fresh air outlet 12 and the second air deflector 30 is controlled to move towards the direction far away from the air outlet 11 of the indoor unit of the air conditioner, the anti-condensation control method further comprises the following steps: controlling the rotating speed of a main fan 40 of the indoor unit of the air conditioner to be reduced; or controlling the rotating speed of a fresh air fan 50 of the indoor unit of the air conditioner to be reduced; alternatively, the rotation speed of the main fan 40 of the indoor air conditioner is controlled to be reduced, and the rotation speed of the fresh air fan 50 of the indoor air conditioner is controlled to be reduced.
The rotating speed of the main fan 40 of the indoor unit of the air conditioner is reduced, so that the air output of the air outlet 11 can be conveniently and effectively reduced, and the temperature difference between a fresh air inlet and the air outlet 11 can be conveniently and effectively reduced; the rotating speed of the fresh air fan 50 of the indoor unit of the air conditioner is reduced, so that the air output of the fresh air port can be effectively reduced, and the temperature difference between the fresh air port and the air outlet 11 can be effectively reduced.
In this embodiment, the air-conditioning indoor unit is the above-mentioned air-conditioning indoor unit; after the first air deflector 20 is controlled to move towards the direction far away from the fresh air outlet 12 and the second air deflector 30 is controlled to move towards the direction far away from the air outlet 11 of the indoor unit of the air conditioner, the anti-condensation control method further comprises the following steps: controlling a fresh air fan 50 of the indoor unit of the air conditioner to operate according to a cyclic mode of a detection period, and detecting the humidity at the fresh air outlet 12 again after each detection period is finished; each detection period includes first controlling the fresh air machine 50 to be turned on for a first preset time, then controlling the fresh air machine 50 to be turned off for a second preset time, and then controlling the fresh air machine 50 to be turned on for a third preset time. By adopting the method, the cyclic control can be conveniently carried out by adopting a cyclic detection mode, so that the control flow is simple, and the condensation condition is conveniently and effectively reduced.
Specifically, since the volatilization time of the cold fluid in the cooling mode and the volatilization time of the hot fluid in the heating mode are different, the first preset time, the second preset time, and the third preset time in the cooling mode are set to be different times from the first preset time, the second preset time, and the third time in the heating mode, respectively. The first preset time, the second preset time and the third preset time are determined by the volatilization time of water at different temperatures. Specifically, the first preset time may be set to the same time value as the third preset time.
In the present embodiment, the anti-condensation logic specifically performs as follows:
combine humidity sensing device to optimize, set up and open when indoor outdoor humidity satisfies the default and prevent the condensation logic, avoid in the low humid environment because the aviation baffle moves to horizontal state between two parties and influence the air supply volume, will have very big improvement to the suitability of preventing the condensation logic and user experience's travelling comfort like this.

In order to further improve the anti-condensation effect, the fresh air opening and closing mode can be set to be that the fresh air opening and closing mode is closed for B hours after being opened for A hours, the fresh air opening and closing mode is opened for A hours, condensation water drops can evaporate in the B hours, the time A-B-A is ase:Sub>A detection period (as step 4, the fresh air fan 50 is closed for 26 minutes after being opened for 45 minutes, then the time A-B-A is started for 45 minutes, the condensation water drops are evaporated after being stopped for 26 minutes, and whether the newly detected humidity reaches ase:Sub>A preset value after the new air fan is started for 45 minutes).

(2) When the detected humidity reaches a preset value and fresh air is started in a heating mode, the fresh air deflector moves downwards (the movement angle is 23 degrees), the upper and lower air sweeping blades of the main air duct move upwards (the movement angle is 32 degrees), and meanwhile, the rotating speed of the main air duct is reduced or the rotating speed of the fresh air is reduced or both reduced (step 1. The rotating speed of the main air duct is reduced from 1200r to 1000r; step 2. The rotating speed of the fresh air is reduced from 1500r to 500r; step 3. The rotating speed of the main air duct is reduced from 1200r to 1100r, and meanwhile, the rotating speed of the fresh air is reduced from 1500r to 700 r), at the moment, the frequency of the compressor is reduced (for example, the frequency of the compressor is reduced from 72Hz to 68 Hz), the heat output by the main air duct and the cold and hot air output by the fresh air are reduced, and therefore, the intersection of cold and hot air flows of two air ports is further reduced. In order to further improve the anti-condensation effect, ase:Sub>A fresh air opening and closing mode can be set to be that after the fresh air opening and closing mode is started for A hours, the fresh air opening and closing mode is closed for B hours, condensation water drops can evaporate in B hours, time A-B-A is ase:Sub>A detection period (as step 4, after the fresh air fan 50 is started for 25 minutes, the fresh air fan is closed for 20 minutes, then the fresh air fan starts for 25 minutes, condensation water drops are evaporated in 20 minutes after the fresh air fan is stopped, and after 25 minutes of the fresh air fan, whether the newly detected humidity reaches ase:Sub>A preset value or not is achieved. And according to different regions and climates, control logics of the combination of the step 1 and the step 4, the combination of the step 2 and the step 4 and the combination of the step 3 and the step 4 can be set, or the logics of the step 1, the step 2 and the step 3 can be directly and independently set without adding the step 4.
Because the output power of the indoor unit of the air conditioner, the rotating speed of the main air duct and the rotating speed of the fresh air duct are different in the refrigeration mode and the refrigeration mode, the reduction of the frequency of the compressor, the reduction range of the rotating speed of the main air duct and the rotating speed range of the fresh air duct are different in the refrigeration mode and the heating mode, the rotating speeds and the time values are convenient to understand and do not form the limitation of the invention.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: when satisfying the user and using the new trend function, can avoid new trend condensation problem, improve user's use travelling comfort.
