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

In one embodiment of the present invention, it is 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 or wireless manner, a timer 42 that checks the current time in real time, and a class method for indoor class conditions. The server control unit 43 sets an operation mode according to the corresponding time and controls the fan speed of the air purifier 1 in the corresponding operation mode according to the environmental information acquired by the indoor environment sensor 2 in response to the corresponding operation mode. ), and a fan control unit 44 that converts 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 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 also communicates with the outdoor environment sensor 3 in a wired or wireless manner, it can transmit outdoor environmental information to the server control unit 43 and the storage unit 46 to be described later.

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

The control operation of the server controller 43 will be described in more detail in the method for purifying indoor air 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 indoor class condition and class method.

The operation mode according to an example may be divided into a first mode, a second mode, and a third mode depending on whether or not a class is held indoors. The first mode may be set as a class time corresponding to a time during which classes are conducted indoors among the times from school attendance to dismissal. The second mode may be set as non-class time corresponding to the remainder of the time from school attendance to dismissal, excluding indoor class time. The third mode may be set to school attendance time corresponding to the time from leaving school on the same day to returning to school the next day and break time corresponding to a day during the week when class is not held indoors. The third mode may be set to the remaining time excluding the first mode and the second mode.

As another example, in setting the operation mode, the server control unit 43 sets the operation mode according to the corresponding time in consideration of the indoor class condition and class method.

At this time, if the above-mentioned class time is extended, if the class time is shortened, considering indoor environment variables such as music time or audio-visual viewing time during class time, 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 that obtains a noise level in the room.

In addition, the server control unit 43 determines the average decibel of indoor noise measured for a specific time period (eg, 10 seconds, 20 seconds, or 30 seconds) according to a specific time interval (eg, 3 seconds or 5 seconds). Since the average decibel is calculated and compared with the reference decibel, the operation mode can be set according to the comparison result in the server controller 43 .

Operation modes according to another example may be classified into a first mode, a second mode, and a third mode according to a comparison between an average decibel and a reference decibel. The first mode may be set as a non-noise time corresponding to a time when the average decibel is smaller than the reference decibel among the times from going to school 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 times from going to school to leaving school. The third mode may be set to school attendance time corresponding to the time from leaving school on the same day to returning to school the next day and break time corresponding to a day during the week when class is not held indoors. The third mode may be set to the remaining time excluding the first mode and the second mode.

At this time, since the indoor environment sensor 2 or the air purifier 1 includes a spacer to prevent noise from entering the decibel sensor, the decibel sensor is not affected by noise such as fan noise, indoor noise, or noise caused by shock. It can be prevented or the effect of noise can be minimized. In addition, since the spacer specifies the visual direction of the sound input unit of the decibel sensor, it filters the sound input to the decibel sensor and prevents direct inflow of noise.

Then, the server controller 43 can control the fan speed according to each mode. In one embodiment of the present invention, controlling 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, or controls the fan speed of the intake fan 60. Correspondingly, the speed of the discharge fan 70 is also controlled.

In one 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 concentration of fine dust in the room as it is. explain by doing

Second, in the second mode, the fan speed can be controlled from the emergency cleaning speed to the maximum speed in response to the environmental information acquired by the indoor environment sensor 2 . For example, by setting an emergency purification rate for each concentration range of fine dust, the indoor air can be quickly purified by rapidly inhaling polluted indoor air during non-class hours. Here, the emergency purification speed is the maximum movable speed 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 is adjusted according to the indoor environment and the surrounding environment. this is possible
