It should be noted that, when the air conditioner executes the condensation preventing program, the operation frequency of the compressor may be decreased, or the operation frequency of the compressor may be decreased while the rotation speed of the fan is increased, or the air conditioner may execute the dehumidification program, etc., and such adjustment and change of the specific execution operation of the condensation preventing program do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
The following describes the technical solution of the present invention in detail with reference to a specific embodiment by taking the example that the preset humidity includes a first preset humidity and a second preset humidity.
As shown in fig. 2, the anti-condensation control method of the present invention includes the steps of:
s100: and acquiring the duration of the running frequency of the compressor which is greater than the preset frequency.
In practical applications, a person skilled in the art can flexibly set a specific value of the preset frequency according to experiments or experiences, for example, the preset frequency is 60HZ, and the controller automatically obtains the duration time that the operating frequency of the compressor is greater than or equal to 60HZ when the air conditioner starts to perform cooling operation or stops performing the anti-condensation program.
S200: and judging whether the duration reaches a first preset time.
The controller is pre-stored with a specific value of the set first preset time, and when the duration of the operating frequency of the compressor is acquired to be greater than or equal to 60HZ, the controller compares the duration with the first preset time.
Illustratively, the first preset time is 2 hours, and when the duration of the operating frequency of the compressor being greater than or equal to 60HZ does not reach 2 hours (the first preset time), S100 and S200 are continuously executed; on the contrary, when the duration of the operation frequency of the compressor ≧ 60HZ reaches 2 hours (first preset time), S300 is then executed.
S300: a humidity value F in the room is obtained.
For example, a humidity sensor may be disposed on a housing of the indoor unit, a remote controller, or other locations in the room, and communicate with the controller, so that the humidity sensor transmits the collected humidity data to the controller in time.
Preferably, the step of "acquiring a humidity value in the room" specifically comprises: and acquiring the humidity value at the air inlet of the indoor unit. Tests show that the judgment result based on the humidity value at the air inlet of the indoor unit is most accurate.
The controller is internally pre-stored with specific values of a first preset humidity and a second preset humidity which are set well, wherein the first preset humidity is smaller than the second preset humidity, and after the humidity value in the room is obtained, the controller compares the humidity value with the first preset humidity and the second preset humidity respectively, and the specific steps are as follows.

After the controller obtains the humidity value F in the room, the humidity value F is compared with the first preset humidity F1, and in practical application, a person skilled in the art can flexibly set a specific numerical value of the first preset humidity F1 according to experiments or experience.
Exemplarily, F1=60%, when the humidity value F < 60% (the first preset humidity F1), it indicates that the humidity in the room is relatively low and the probability of generating condensation is small, in this case, the air conditioner is not caused to perform the condensation preventing process, and the humidity value in the room is continuously obtained, i.e., S300 is continuously performed; on the contrary, when the humidity value F is equal to or greater than 60% (the first preset humidity F1), it means that the humidity in the room is relatively high and the possibility of generating condensation is high, and in this case, it is necessary to cause the air conditioner to perform the condensation preventing process.
In a preferred case, the condensation preventing program includes a first condensation preventing program, a second condensation preventing program, a third condensation preventing program, and a fourth condensation preventing program, wherein a frequency of the compressor is decreased by a smaller magnitude when the air conditioner performs the first condensation preventing program than when the second condensation preventing program or the third condensation preventing program is performed, and a rotational speed of the fan of the indoor unit is increased by a smaller magnitude when the air conditioner performs the first condensation preventing program than when the second condensation preventing program or the third condensation preventing program is performed; the fourth condensation preventing program is a dehumidifying program.
Illustratively, when the air conditioner executes a first anti-condensation program, the rotating speed of the fan is increased by 10% on the basis of the original rotating speed, and the operating frequency of the compressor is reduced to 90% of the original operating frequency; when the air conditioner executes a second anti-condensation program, the rotating speed of the fan is increased by 20% on the basis of the original rotating speed, and the operating frequency of the compressor is reduced to 70% of the original operating frequency; when the air conditioner executes the third condensation prevention program, the rotating speed of the fan is increased by 15% on the basis of the original rotating speed, and the operating frequency of the compressor is reduced to 80% of the original operating frequency.
When the humidity value F is greater than or equal to 60% (the first predetermined humidity F1), it is necessary to further determine which of the above-described anti-condensation processes is to be executed by the air conditioner.
S420: and judging whether the humidity value F is greater than a second preset humidity F2.
When the humidity value F is judged to be greater than or equal to 60% (the first preset humidity F1), the humidity value F is further compared with the second preset humidity F2, and in practical application, a person skilled in the art can flexibly set a specific numerical value of the second preset humidity F2 according to experiments or experience.
Exemplarily, F2=80%, when 60% ≦ F < 80%, indicating that the humidity in the room is not too high yet, in which case the user' S opinion needs to be solicited, as in particular S510 to S560; when the humidity in the room is higher than or equal to 80% and less than or equal to F, in this case, the user does not need to be asked for an opinion, and the air conditioner can be directly made to execute the anti-condensation program, but it needs to be determined which anti-condensation program is to be executed by the air conditioner according to the personnel condition in the room, specifically, S570 to S600.
S510: and judging whether a person exists in the room.
Illustratively, an image acquisition device, such as a camera, may be installed on the casing of the indoor unit or other locations in the room, and the camera may communicate with the controller, so that the camera may transmit the acquired image data to the controller in time, and the controller may determine whether there is a person in the room according to the acquired image of the room, and then perform S520 if there is no person in the room, or perform S530 if there is a person in the room.
S520: and judging whether the duration of no person in the room is less than a second preset time.
And in practical application, a person skilled in the art can flexibly set a specific value of the second preset time according to experience.
Illustratively, the second preset time is 10 minutes, and when the duration of no person in the room is less than 10 minutes (the second preset time), S530 is executed next, and when the duration of no person in the room is greater than or equal to 10 minutes (the second preset time), S560 is executed next.
S530: the air conditioner is enabled to send out prompt information for executing the anti-condensation program.
And under the condition that people exist in the room and the condition that the duration time of no people in the room is less than the second preset time, the air conditioner sends prompt information for executing the anti-condensation program to the user. For example, a voice player may be installed on the indoor unit, and the voice player plays voice information to prompt the user, or the air conditioner may also send a short message prompt to the mobile phone of the user to prompt the user, and the like, and such adjustment and change of the specific prompting manner do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
After the air conditioner issues the prompt message that the anti-condensation program needs to be executed, step S540 is performed.
S540: and judging whether the confirmation information of the user is received or not.
If the confirmation information of the user is not received within the preset time, it indicates that the user does not want to enable the air conditioner to execute the anti-condensation program, and in this case, the air conditioner is not enabled to execute the anti-condensation program, and S300 can be continuously executed; if the confirmation information of the user is received, indicating that the user agrees to have the air conditioner perform the anti-condensation process, S550 is then performed.
S550: the air conditioner is made to execute a first condensation preventing program.
Under the condition that someone is in the room, and under the condition that nobody's duration is less than the second preset time in the room, make the air conditioner carry out first condensation program of preventing, compare in the second and prevent condensation program and third condensation program, when carrying out first condensation program of preventing, the range that the frequency that makes the rotational speed of fan improve and the compressor reduces all is less, through such setting, can minimize the influence to user experience.
After the air conditioner executes the first anti-condensation program, the controller can automatically record the time of the air conditioner executing the first anti-condensation program, and when the time of the air conditioner executing the first anti-condensation program reaches third preset time, the air conditioner stops executing the first anti-condensation program. After the air conditioner stops executing the first condensation preventing program, the air conditioner continues to execute the step S100, that is, a new round of judgment is performed.
It should be noted that, in practical applications, a person skilled in the art may flexibly set the specific value of the third preset time according to experiments or experience. Illustratively, the third preset time is 30 minutes, and when the time for the air conditioner to execute the first condensation preventing program reaches 30 minutes, the air conditioner is stopped from executing the first condensation preventing program.
S560: and enabling the air conditioner to execute a second condensation preventing program.
Under the condition that the duration time of no person in the room is greater than or equal to the second preset time, the air conditioner is enabled to execute the second condensation preventing program, and compared with the first condensation preventing program, when the second condensation preventing program is executed, the range of increasing the rotating speed of the fan and the range of reducing the frequency of the compressor are large, and through the arrangement, a better condensation preventing effect can be obtained.
After the air conditioner executes the second anti-condensation program, the controller can automatically record the time for the air conditioner to execute the second anti-condensation program, and when the time for the air conditioner to execute the second anti-condensation program reaches the fourth preset time, the air conditioner stops executing the second anti-condensation program. After the air conditioner stops executing the second condensation preventing program, the air conditioner continues to execute the step S100, that is, a new round of judgment is performed.

Illustratively, the fourth preset time is 45 minutes, and when the time for the air conditioner to execute the second condensation preventing program reaches 45 minutes, the air conditioner is stopped from executing the second condensation preventing program.
S570: and judging whether a person exists in the room.
When the humidity value in the room is greater than or equal to the second preset humidity, it is also necessary to determine whether there is a person in the room, and if there is no person in the room, then S580 is performed; if there is a person in the room, S590 is then performed.

And when the duration time of no person in the room is greater than or equal to the second preset time, the air conditioner is enabled to execute the dehumidification program, so that the humidity in the room can be reduced as soon as possible.
And in the process of executing the dehumidification program by the air conditioner, the humidity value in the room is still detected, and when the humidity in the room is reduced to be lower than a third preset humidity, the air conditioner stops executing the dehumidification program, wherein the third preset humidity is lower than the second preset humidity. After the air conditioner stops executing the dehumidification program, the process continues to execute S100, i.e., a new round of judgment is performed.
