In some embodiments, in the method for controlling an indoor unit 100 of an air conditioner according to the embodiments of the present invention, the step of obtaining an environmental parameter of an indoor environment in which the indoor unit 100 is located includes: the PM2.5 value of the indoor environment in which the indoor unit 100 is located is obtained.
The fan assembly 50 of the indoor unit 100 of the air conditioner according to the embodiment of the present invention further includes: and a filter module 59 disposed in the cover 53 to filter air introduced into the cover 53. In the control method of the air-conditioning indoor unit 100 according to the embodiment of the present invention, the steps of controlling the opening and closing of the fan 54, the first inlet 531, the second inlet 532, and the sweeping robot 94 based on the environmental parameters include:
judging whether the PM2.5 value is greater than a first preset concentration threshold value or not;
if yes, the sweeping robot 94 is controlled to be turned on, the fan 54 is turned on, the first inlet 531 is turned on, and the second inlet 532 is turned off.
The first preset concentration threshold is a PM2.5 range value when the concentration of the suspended fine particles in the air meets the standard. The setting may be based on national standards, or may be based on the requirements of the user, and is usually based on national standards. When the PM2.5 value is greater than the first preset concentration threshold value, which indicates that dust may be deposited on the floor at this time, the fan 54 is controlled to be opened, the first inlet 531 is opened, and the second inlet 532 is closed, that is, the fan assembly 50 performs internal circulation to remove PM2.5 particles in the indoor air by using the filter module, and the sweeping robot 94 starts to operate to remove the dust.
After the fan 54 is controlled to be turned on, the first inlet 531 is turned on, and the second inlet 532 is turned off for a period of time, the control method of the indoor unit 100 of the air conditioner according to the embodiment of the present invention further includes:
judging whether the PM2.5 value is less than or equal to a first preset concentration threshold value or not;
if so, the fan 54 is controlled to be opened, the first inlet 531 is closed, and the second inlet 532 is opened.
When the PM2.5 value is less than or equal to the first preset concentration threshold, which indicates that the concentration of suspended particles in the indoor air meets the requirement, the fan 54 is turned on, the first inlet 531 is closed, and the second inlet 532 is opened, that is, the fan assembly 50 performs an external circulation to introduce fresh air to the outdoor.
The turning-off time of the sweeping robot 94 can be controlled by determining whether the number of times the sweeping robot 94 sweeps the indoor floor reaches a preset number threshold. The predetermined number threshold is usually 1, but may be 2 to 3. That is, after the sweeping robot 94 is controlled to be turned on, the sweeping robot 94 can be controlled to be turned off after the sweeping robot 94 is detected to sweep the indoor floor for one time.
Meanwhile, considering that some dust may be raised in the indoor air during the operation of the sweeping robot 94, the time for controlling the fan assembly 50 to perform the external circulation should be after the sweeping robot 94 is turned off. That is, before the step of controlling the fan 54 to be turned on, the first inlet 531 to be closed, and the second inlet 532 to be opened, the method further includes:
judging whether the sweeping robot 94 is in a closed state;
if so, the fan 54 is controlled to be opened, the first inlet 531 is closed, and the second inlet 532 is opened.
After the step of controlling the fan assembly 50 to perform the outer circulation, that is, after the step of controlling the fan 54 to be opened, the first inlet 531 to be closed and the second inlet 532 to be opened, the method further comprises the following steps:
acquiring a carbon dioxide concentration value of an indoor environment where the indoor unit 100 is located;
judging whether the carbon dioxide concentration value is less than or equal to a second preset concentration threshold value or not;
if yes, the fan 54 is controlled to be turned off.
The second preset concentration threshold is a carbon dioxide concentration range value when the carbon dioxide concentration in the air reaches the standard. The setting may be based on national standards, or may be based on the requirements of the user, and is usually based on national standards. When the carbon dioxide concentration of the indoor air is less than or equal to the second predetermined concentration threshold, indicating that the indoor air has been ventilated, the fan assembly 50 may be controlled to stop working even if the fan 54 is turned off. At this time, the states of the first and second inlets 531 and 532 may be maintained in the current state, i.e., the first inlet 531 is closed and the second inlet 532 is open.
Fig. 11 is a detailed flowchart illustrating a control method of the air conditioning indoor unit 100 shown in fig. 1. The control method of the air-conditioning indoor unit 100 of the embodiment of the invention comprises the following steps:
s202: the PM2.5 value of the indoor environment in which the indoor unit 100 is located is obtained.
