In embodiments of the present invention, 1 corresponding humidity information of air conditioner can be the ambient humidity residing for air conditioner 1.It needs
It is noted that when air conditioner 1 is freezed under relatively high humidity environment, it is easy in interior machine structural member surface or air duct
Middle condensation water.It is, condensation water generation is directly related with the damp condition in environment.In embodiments of the present invention, institute is obtained
The mode for stating 1 corresponding humidity information of air conditioner can be following any：1, air conditioner 1 and extraneous network communication, to lead to
It crosses extraneous network and obtains local humidity；2, air conditioner 1 can utilize technology of Internet of things from it is indoor other with humidity collection unit
Household electrical appliances in get the humidity information of corresponding environment.3, humidity sensor is directly set in air conditioner 1 to detect room
Between humidity.In the above method, employing mode 1 or 2, can be effective without additionally installing humidity sensor additional on air conditioner 1
Save the cost of air-conditioning.The data that employing mode 3 obtains are more accurate, and what is be convenient for arrives accurate analysis result.
It is alternatively possible to be when 1 refrigeration mode of air conditioner starts, according in the selection of the actual disposition situation of air conditioner 1
It states any mode and obtains the humidity information that the air conditioner 1 corresponds to environment.For example, after the startup of 1 refrigeration mode of air conditioner,
If air conditioner 1 is the air conditioner 1 that can network but not have humidity sensor, pass-through mode 1 obtains the wet of corresponding environment
Spend information；If air conditioner 1 has Internet of Things communication unit, and can carry out data with other household electrical appliances with humidity sensor
Interaction can then obtain the humidity information of corresponding environment with pass-through mode 2；If air conditioner 1 itself is configured with humidity sensor,
Direct employing mode 3 obtains the humidity information of corresponding environment.
Step S102 judges whether to need to enter anti-condensation pattern.
In embodiments of the present invention, judge whether the humidity information obtained is not less than the first humidity threshold.If the humidity

The corresponding control strategy in humidity section belonging to the humidity information controls wind-guiding door and the work of inner blower of the air conditioner 1
State.Optionally, first judge the humidity section belonging to humidity information.It is (in i.e. wet to belong to the first humidity section in the humidity information
Spend section) when, the wind-guiding door is adjusted into angular range from the first conventional range shorter to preset second range, and control
The inner blower is made still to run according to current rotating speed.It is, in the case where meeting this damp condition, air conditioner 1 only needs limitation to lead
The adjusting angular range of air door.For example, 1 wind-guiding door of air conditioner is during conventional operation, wind-guiding door can be in the control of air conditioner 1
It can be under system【a0~b0】Between adjust the angle.Belong to the first humidity province entering anti-condensation pattern and corresponding humidity information
Between when, can be by the adjustable-angle range shorter of wind-guiding door【a1~b1】, wind-guiding door can under the control of air conditioner 1
With【a1~b1】Between adjust the angle.
When the humidity information belongs to the second humidity section (i.e. high humility section), by the adjusting angle model of the wind-guiding door
It encloses from the first conventional range shorter to preset second range, and is pressed on the basis of the current rotating speed of the inner blower
According to preset adjustment value, the running speed of the inner blower is improved.Above-mentioned current rotating speed can refer to the currently operation wind of air conditioner 1
Rotating speed corresponding to shelves.For example, currently the corresponding rotating speed of wind shelves is r, preset adjustment value is Δ r, is determining humidity information category
When the second humidity section, other than the wind-guiding door of adjustment air conditioner 1, it is also necessary to which the rotating speed for controlling inner blower is promoted to r+ Δs
r。
As shown in Fig. 2, above-mentioned condensation prevention control method can also include the following steps：
Step S104 judges whether that anti-condensation pattern can be exited.
In embodiments of the present invention, the mode that judgement needs to exit anti-condensation pattern includes following at least one：
Optionally, the operation duration under anti-condensation pattern of air conditioner 1 is obtained, is more than preset duration threshold value in the operation duration
When, it is judged to needing to exit anti-condensation pattern.
Optionally, 1 corresponding humidity information of air conditioner is obtained in real time, when the humidity information is less than third humidity threshold,
It is judged to needing to exit anti-condensation pattern.It should be noted that above-mentioned third humidity threshold is less than the first humidity threshold.
Step S105 exits anti-condensation pattern after judgement needs to exit anti-condensation pattern, makes 1 normal operation of air conditioner.
In embodiments of the present invention, the mode for exiting anti-condensation pattern may include：By the adjustable-angle model of wind-guiding door
It encloses and restores to the first conventional range, the inner blower of control air conditioner 1 continues to run with the corresponding rotating speed of current wind shelves.
