The operating state of the compressor 140, the operating state of the inner fan 160 of the air conditioner 100, and the operating state of the damper 130 of the air conditioner 100 are controlled according to the temperature data.
It should be noted that, in order to protect the evaporator 150, and to achieve that the frequency of the compressor 140 can be automatically adjusted in the mildew-proof process, and the temperature of the internal evaporator 150 is self-adapted according to the temperature of the internal evaporator 150, in this embodiment, the operation state of the compressor 140, the operation state of the internal fan 160 of the air conditioner 100, and the operation state of the air guide door 130 of the air conditioner 100 are controlled according to the temperature data, and the operation modes mainly include three mildew-proof modes:
the first mould proof mode: when the temperature of the evaporator 150 is too high, the compressor 140 stops operating, and the condensed water on the evaporator 150 is treated by operating the inner fan 160 and opening the air guide door 130.
The second mould proof mode: when the temperature of the evaporator 150 is high, the compressor 140 is operated at a low frequency, and the inner fan 160 is operated, and the air guide door 130 is opened to treat the condensed water on the evaporator 150.
And a third mildew prevention mode: when the temperature of the evaporator 150 is relatively low, the damper 130 and the inner fan 160 are not opened, the influence on the user is reduced, and the condensed water on the evaporator 150 is treated only by operating the compressor 140.
It should be noted that, the third mold prevention mode can be further divided into two sub-modes according to the relative temperature of the evaporator 150:
the first mould-proof sub-mode: when the evaporator 150 is at a low temperature, the condensed water on the evaporator 150 is treated by operating the compressor 140 at a higher frequency than the operating frequency of the compressor 140 in the second mold proof mode without opening the damper 130 and the inner fan 160.
The second mould-proof sub-mode: when the temperature of the evaporator 150 is lower, the condensed water on the evaporator 150 is treated by operating the compressor 140 at a higher frequency than the operating frequency of the compressor 140 in the first mold-proof sub-mode without opening the damper 130 and the inner fan 160.
It should be understood that the operation state of the compressor 140, the operation state of the inner fan 160 of the air conditioner 100, and the operation state of the air guide door 130 of the air conditioner 100 may include the open or closed states of the compressor 140, the inner fan 160, and the air guide door 130, and may also include the open times of the compressor 140, the inner fan 160, and the air guide door 130.
Alternatively, in this embodiment, the step of controlling the operation state of the compressor 140, the operation state of the inner fan 160 of the air conditioner 100, and the operation state of the damper 130 of the air conditioner 100 according to the temperature data may include the steps of:
step S171: and judging the data interval of the temperature data.

It can be understood that T2＞T3。
Step S1721: if the temperature data is less than the first preset temperature and not less than the second preset temperature (T)2≤T＜T1) Then the inner fan 160 is controlled to operate and the air guide door 130 is controlled to open, and at the same time, the compressor 140 is controlled to operate at the first frequency, wherein the first frequency is denoted as F1。
If the temperature data is less than the second preset temperature, the inner fan 160 and the air guide door 130 are controlled to be closed, and the compressor 140 is controlled to continue to operate. The step may further include:
step S1722: if the temperature data is not less than the third preset temperature and less than the second preset temperature (T)3≤T＜T2) Then the compressor 140 is controlled to operate at the second frequency; wherein the second frequency is denoted as F2The second frequency is greater than or equal to the first frequency (F)2≥F1)。
Step S1723: if the temperature data is less than the third preset temperature (T < T)3) Then the compressor 140 is controlled to operate at the third frequency; wherein the third frequency is denoted as F3The third frequency is greater than or equal to the second frequency (F)3≥F2)。
The controlling of the operation state of the compressor 140, the operation state of the inner fan 160 of the air conditioner 100, and the operation state of the damper 130 of the air conditioner 100 according to the temperature data may further include:
step S1724: if the temperature data is not less than the first preset temperature (T is more than or equal to T)1) The compressor 140 is controlled to stop operating, the inner fan 160 is controlled to operate, and the air guide door 130 is controlled to open.
It should be understood that after the step S1724, the mildew control method may further include the steps of:

It is understood that the operation time period of the first mold prevention mode may be a time period during which the inner blower 160 is operated or a time period during which the damper 130 is opened.
Or judging whether the temperature data is smaller than a preset temperature value (marked as T)Is provided with)。
Alternatively, the preset temperature value may be a third preset temperature T3(TIs provided with＝T3)。
Step S191: if the inner fan 160 is operated for a preset time and/or the air guiding door 130 is opened for a preset time, (N > N)Is provided with) The inner fan 160 is controlled to stop running, the air guide door 130 is controlled to be closed, and the mildew-proof function is quitted; or,
if the temperature data is less than the preset temperature value (T < T)Is provided with) If so, the inner fan 160 is controlled to stop running, the air guide door 130 is controlled to be closed, and the mildew-proof function is exited.
