Example 1
As shown in fig. 4, when the room needs to be dedusted, the control method of the embodiment includes the following steps:
s110: the air humidity in the room is acquired.

After the concentration of the particles and the air humidity in the room are obtained, it is determined whether the humidity of the room needs to be reduced according to the concentration of the particles and the air humidity.
Specifically, the concentration of the particles is compared with a preset concentration; comparing the air humidity with a first preset humidity and a second preset humidity respectively, wherein the first preset humidity is greater than the second preset humidity; and then judging whether the humidity of the room needs to be reduced according to the comparison result. Illustratively, steps S130, S140 and S150 can be seen.
S130: and judging whether the air humidity is higher than a first preset humidity.
After the air humidity of the room is obtained, the air humidity may be compared with the first preset humidity, and if the air humidity is greater than the first preset humidity, it is indicated that the humidity of the room is very high, in this case, it may be directly determined that the humidity of the room needs to be reduced, and step S200 may be directly performed; otherwise, if the humidity of the air is not greater than the first preset humidity, step S140 is then performed.
S140: and judging whether the air humidity is higher than a second preset humidity.
If the air humidity is less than or equal to the first preset humidity, continuing to compare the air humidity with the second preset humidity, and if the air humidity is not greater than the second preset humidity, indicating that the humidity of the room is relatively low, in this case, it may be directly determined that the humidity of the room does not need to be reduced, and step S300 may be directly performed; otherwise, if the air humidity is greater than the second preset humidity, step S150 is then performed.
S150: and judging whether the concentration of the particles is larger than a preset concentration.
Comparing the concentration of particles in the room with a preset concentration when the air humidity is less than or equal to a first preset humidity but greater than a second preset humidity, and if the concentration of particles is greater than the preset concentration, indicating that the concentration of particles in the room is relatively high, in this case, determining that the humidity of the room needs to be reduced, executing step S200 first, and then executing step S300; otherwise, if the concentration of the particles is not greater than the preset concentration, it is determined that the humidity of the room does not need to be reduced, step S300 is directly performed.
S200: reducing the humidity of the room.
When the air humidity is higher than the first preset humidity, the air conditioner executes a dehumidification mode to reduce the humidity of the room, and when the air humidity is reduced to the first preset humidity, the air conditioner is switched to a heating mode to continuously reduce the humidity of the room.
When the air humidity is greater than the second preset humidity and less than or equal to the first preset humidity, the air conditioner is made to execute a heating mode to reduce the humidity of the room.
S300: causing the air conditioner to perform a dust removing mode.
It should be noted that, in practical applications, a person skilled in the art may flexibly set specific values of the first preset humidity, the second preset humidity, and the preset concentration according to experiments.
Preferably, in the case where the concentration of the particles in the room is greater than the preset concentration, the step of "causing the air conditioner to perform the dust removal mode" specifically includes: firstly, enabling the IFD dust removing device to move to a non-working position; and when the running time of the ion emitting device reaches the preset time, the IFD dust removing device is moved to the working position.
By such arrangement, the dust removal efficiency of the room can be further improved.
Specifically, the application divides the whole dust removal stage into two stages, in the first stage of dust removal, the aim is to fully fuse charged ions sprayed by the ion emission device with particles in a room, in the first stage, the IFD dust removal device is moved to a non-working position, the flow speed of air in the room can be accelerated, the fusion efficiency of the charged ions and the particles is improved, the first stage is finished, the second stage is entered, and then the IFD dust removal device is moved to the working position to cover an air inlet, so that the charged ions in the air are absorbed, and the aim of purifying the air is achieved.
Preferably, the control method of the present application further includes: after the dust removal of the room is finished, the fragrance module is started and the fan is continuously operated.
Example two
The main difference between the present embodiment and the first embodiment is that the steps for determining whether to reduce the humidity of the room are different, and the other steps are the same as those of the first embodiment, so that the description thereof will not be repeated.
Specifically, in the present embodiment, the step of "determining whether the humidity of the room needs to be reduced" specifically includes: acquiring the air humidity in the room; comparing the air humidity with a preset humidity; if the air humidity is greater than the preset humidity, judging that the humidity of the room needs to be reduced; if the air humidity is less than or equal to the preset humidity, it is determined that the humidity of the room does not need to be reduced.
That is, in the present embodiment, it is determined whether or not it is necessary to reduce the humidity of the room based only on the humidity of the air in the room. In practical applications, a specific value of the preset humidity may be set by a person skilled in the art according to experiments or experience.
It should be noted that, the above-described control method may be executed by the controller of the air conditioner.
