The indoor environment sensor 2 is installed indoors. The indoor environment sensor 2 acquires indoor environmental information including at least indoor fine dust concentration in the room. Here, the indoor fine dust concentration can be measured by dividing it into general fine dust (PM10) and ultrafine dust (PM2.5). The indoor environmental information may further include indoor temperature, indoor humidity, and the like. Some or all of the indoor environmental sensor may be provided in the air purifier 1 described above.

An embodiment of the present invention will be described based on ultrafine dust (PM2.5). However, since the numerical ratio of dust is applied, it can also be applied based on general fine dust (PM10).

The control server 4 may include a control body 4a for controlling the fan speed of the air purifier 1 , and a display 4b displaying a state in which the fan speed of the air purifier 1 is controlled.

The control body 4a of the control server 4 includes a communication unit 41 that communicates with the indoor environment sensor 2 in a wired/wireless manner, a timer 42 that checks the current time in real time, and a class state class method indoors. Server control unit 43 that sets the operation mode according to the corresponding time in consideration of ) and a fan control unit 44 that converts the information on the fan speed determined by the server control unit 43 into a signal to be transmitted to the air purifier 1 .

The communication unit may receive the indoor environment information and transmit it to the server control unit 43 or a storage unit 46 to be described later. Since the communication unit 41 communicates with the outdoor environment sensor 3 in a wired or wireless manner, the outdoor environment information can be transmitted to the server control unit 43 and the storage unit 46 to be described later.

The timer 42 may apply various types of known current time measurement units.

The control operation of the server controller 43 will be described in more detail in the indoor air purification method according to an embodiment of the present invention.

For example, in setting the operation mode, the server controller 43 sets the operation mode according to the corresponding time in consideration of the class state and the class method in the room.

The operation mode according to an example may be divided into a first mode, a second mode, and a third mode according to whether or not a class is performed indoors. The first mode may be set as a class time corresponding to a time during which a class is conducted indoors among the time from going to school to leaving school. The second mode can be set as non-class time that applies to the rest of the time from going to school to leaving school except for the indoor class time. The third mode can be set as the commute time, which corresponds to the time from leaving school on the same day to the next day, and the rest time, which corresponds to the days when classes are not held indoors during the week. The third mode may be set to the remaining time except for the first mode and the second mode.

As another example, in setting the operation mode, the server controller 43 sets the operation mode according to the corresponding time in consideration of the class state and the class method in the room.

At this time, if the above-mentioned class time is extended, class time is shortened, if indoor environment variables such as music time or audiovisual viewing time are taken into consideration during class, the indoor environment may change depending on the type of class and class method on the day. can

Accordingly, the indoor environment sensor 2 may further include a decibel sensor for acquiring the indoor noise level.

And the server control unit 43 measures the average decibel of the indoor noise measured for a specific time (for example, 10 seconds or 20 seconds or 30 seconds, etc.) according to a specific time interval (for example, 3 seconds or 5 seconds, etc.) Since the calculation is performed and the average decibel and the reference decibel are compared, the operation mode can be set according to the comparison result in the server control unit 43 .

The operation mode according to another example may be divided into a first mode, a second mode, and a third mode according to a comparison between the average decibel and the reference decibel. The first mode may be set as a non-noise time corresponding to a time when the average decibel is less than the reference decibel among the time from school arrival to leaving school. The second mode may be set as a noise time corresponding to a time when the average decibel is equal to or greater than the reference decibel among the time from school arrival to leaving school. The third mode can be set as the commute time, which corresponds to the time from leaving school on the same day to the next school day, and the rest time, which corresponds to days when classes are not held indoors during the week. The third mode may be set to the remaining time except for the first mode and the second mode.

At this time, since the indoor environmental sensor 2 or the air purifier 1 includes a spacer to prevent noise from entering the decibel sensor, the decibel sensor can reduce the effect of noise such as fan noise or indoor noise or noise caused by impact. It can be avoided or the effect of noise can be minimized. In addition, since the spacer specifies the gaze direction of the sound input unit of the decibel sensor, it filters the sound input to the decibel sensor and prevents the direct inflow of noise.

Then, the server controller 43 may control the fan speed according to each mode. In one embodiment of the present invention, control of the fan speed based on the intake fan 60 will be described. However, the fan speed controlled by the server control unit 43 controls both the intake fan 60 and the exhaust fan 70 or only the exhaust fan 70, controls the fan speed of the intake fan 60, and thus In response, the speed of the exhaust fan 70 is also controlled.

In an embodiment of the present invention, the control fan speed of the intake fan 60 is set to 0% to 100% based on the maximum fan speed of the intake fan 60, and the control concentration of fine dust is set to the indoor fine dust concentration as it is. described as doing

First, in the first mode, even if the environmental information acquired by the indoor environmental sensor 2 exceeds a preset measurement range, the fan speed may be controlled so as not to exceed the do not disturb speed. For example, even if the fine dust concentration of bad or higher is obtained, the control fan speed should not exceed the Do Not Disturb speed to purify fine dust during class time as well as minimize the noise generated by the air purifier (1) to reduce noise to class. Make sure it is not disturbed. Here, the Do Not Disturb speed was set to 50% of the maximum speed of the fan at a noise level that would not interfere with class, but is not limited thereto, and can be adjusted according to the indoor environment and surrounding environment.

Second, in the second mode, the fan speed can be controlled from the emergency purification speed to the maximum speed in response to the environmental information obtained by the indoor environment sensor 2 . For example, by setting an emergency purification speed for each concentration range of fine dust, it is possible to quickly inhale the indoor air polluted outside of class and purify the indoor air in a short time. Here, the emergency purification speed is the maximum speed that can be operated for each range of fine dust concentration, and the minimum value of the emergency purification speed is set to 50% of the maximum speed of the fan, but is not limited thereto, and adjusted according to the indoor environment and surrounding environment This is possible.

According to an embodiment of the present invention, the control fan speed for each fine dust concentration in the third mode is shown in Table 3 below.

density 0-10 11-20 21-30 31-40 41-50 51 to 60 61-70 71~80 81-90 91 to 100 101~ speed 5 15 25 35 45 55 65 75 85 95 100
