Description

TECHNICAL FIELD [0001] The present invention relates to an air cleaner control method and an air cleaner,

The present invention relates to an air purifier control method and an air purifier, and more particularly, to a purifier for precisely measuring a substance contained in contaminated air and purifying the air efficiently.

Recently, as the severity of environmental pollution increases, interest in indoor air pollution problem is increasing. In particular, the demand for air purifiers capable of purifying the indoor air from a large number of users is rapidly increasing due to the seriousness of indoor air pollution during environmental pollution.

An air purifier or an air purifier means a device that filters dust or germs in the air to clean the air.

The demand for such air cleaners is steadily increasing. The air purifier mainly uses a mechanical method based on a charcoal filter that performs a dust collection function with a hepa filter and a deodorization function .

Here, the activated carbon filter means a filter for removing odor and harmful gas contained in the air using activated carbon. That is, since the activated carbon filter has a deodorizing function as described above, performance deteriorates over time, and costs are incurred by periodically replacing the filter. Particularly, the activated carbon filter is disadvantageous in that the removal efficiency of formaldehyde and VOCs (Volatile Organic Compounds), which are the main substances causing phosphorus syndrome phosphorus, is not good, and recently, a photocatalyst (for example, titanium dioxide Or air cleaners using oxidation catalysts such as nano metal catalysts have been developed.

However, the conventional air purifier control method has recently been problematic in that it effectively removes formaldehyde, fine dust, VOCs, and the like, which are major causes of air pollution, and improves the devitrification efficiency.

2 is a flowchart illustrating a method of controlling an air cleaner according to an embodiment of the present invention. Hereinafter, it is noted that the air cleaner may be referred to as an operation performed by the control unit 190 in the air cleaner.

Referring to FIG. 2, the air purifier according to an embodiment of the present invention is turned on when a user presses a power button to turn on the power (S210).

The air cleaner confirms the operation mode (S211). For example, the operation mode may include a manual mode, an automatic mode, and a robust mode depending on a user's setting. Here, the manual mode is a mode in which the user operates the fan 120 to adjust the intensity or intensity of the ionizer 140 and the ionizer 140. The automatic mode is a mode in which the air cleaner adjusts the intensity of the fan 120 The intensity mode is a type of automatic mode or more powerful than the automatic mode in that the intensity of the fan 120 and the intensity of the ionizer 140 It is a mode that performs operations such as operation or intensity.

For example, when the operation mode is the manual mode, the air purifier displays white on the plurality of LEDs (LEDs) 160 on the display unit 160, while the brightness of the manual mode is weak, It is possible to rotate a plurality of LEDs.

If the operation mode is the strong mode, the air purifier displays the predetermined strong mode brightness and strong mode color through the display unit 160 (S213). For example, when the operation mode is the powerful mode, the air purifier displays white light on a plurality of LEDs (LEDs) 160 on the display unit 160, It is possible to rotate a plurality of LEDs.

If the operation mode is the automatic mode, the air purifier displays the predetermined automatic mode brightness and the automatic mode color through the display unit 160 (S214). For example, when the operation mode is the powerful mode, the air purifier displays red, blue, green, blue, and red in the order of a plurality of LEDs (LEDs) The LEDs are turned on in the unit of 5 seconds, and the plurality of LEDs can be rotated.

The next step is a process that can be performed in the automatic mode. However, depending on the embodiment, it can operate in the robust mode.

The air cleaner measures the temperature at the temperature sensor 101, the humidity at the humidity sensor 102, the fine dust at the fine dust sensor 103, the formaldehyde at the formaldehyde sensor 104 , And the volatile organic compound sensor 105 measures the volatile organic compound.

The air cleaner confirms the temperature measured by the temperature sensor 101 and the humidity measured by the humidity sensor 102 (S215).

At this time, the air cleaner can display the temperature measured by the temperature sensor 101 and the humidity measured by the humidity sensor 102 through the display unit 160. For example, the display unit 160 can display the temperature and humidity values on the display.

The air cleaner confirms fine dust information measured by the fine dust sensor 103, formaldehyde information measured by the formaldehyde sensor 104, and volatile organic compound information measured by a volatile organic compounds (VOCs) sensor (S216).

The air cleaner determines the air condition (or air quality) using fine dust information, formaldehyde information, and volatile organic compound information (S217). For example, the air condition can be subdivided into a first state (good), a second state (normal), and a third state (poor). However, it should be noted that the air condition can be further subdivided according to the embodiment.

 Table 1 below shows the air status as an example. These embodiments are possible in various embodiments.

standard fine dust
PM1.0 Fine dust PM2.5 Fine dust PM10 Formaldehyde Volatile organic compounds
(VOCs) First state (good) 0 to 15 0 to 15 0 to 30 0.03 or less Less than 50 Second state (usually) 16 to 50 16 to 25 31 to 50 0.03 to 0.08 50 to 300 Third state (bad) 51 or more 26 or more 51 or more 0.08 or more 300 or more

Here, the unit of fine dust is ug / m 3, the unit of formaldehyde is ppm, and the unit of volatile organic compound (VOCs) is ppm.

At this time, in the first condition (good), the fine dust PM1.0 is 0 to 15, the fine dust PM2.5 is 0 to 15, the fine dust PM10 is 0 to 30, the formaldehyde is 0.03 ppm or less, the volatile organic compound VOCs) is 50 or less.

In the second state (normal), the fine dust PM1.0 is 16 to 50, the fine dust PM2.5 is 16 to 25, the fine dust PM10 is 31 to 50, the formaldehyde is 0.03 to 0.08, the volatile organic compounds (VOCs) ≪ / RTI >

In the third state (poor), fine dust PM1.0 is at least 51, fine dust PM2.5 is at least 26, fine dust PM10 is at least 51, formaldehyde is at least 0.08, and volatile organic compounds (VOCs) are at least 300.

The air purifier performs a predetermined first stage operation according to the air condition (S218). Here, it is possible to perform the first stage operation, the second stage operation, the third stage operation, and the like, which are predetermined first stage small steps.

At this time, the air purifier performs the first step operation when the air condition is the first state, performs the second step operation when the air condition is the second condition, and performs the second step operation when the air condition is the third condition, Step operation may be performed.

For example, if the first stage small air cleaner causes the fan 120 to operate weakly, the ionizer 140 will not operate, and the second stage small air cleaner will cause the fan 120 to operate at medium intensity , It is possible to cause the ionizer 140 to operate weakly and the third stage small air cleaner to operate the fan 120 with strong intensity and the ionizer 140 to operate strongly.

By doing so, the air purifier performs a predetermined step operation according to the situation, thereby purifying the air while purifying the unnecessary power, and adjusting the noise emitted from the air purification.

The air purifier can store the air condition and the operating condition in the memory 180. At this time, the air cleaner can store the air condition and the operating condition in the memory 180 in a database.

The air cleaner receives the air pollution degree information from the outside, judges the air condition by using the fine dust information, the formaldehyde information, the volatile organic compound non-information and the air pollution degree information, and performs a predetermined second stage operation (S219) . Here, various embodiments are possible according to the preliminarily set second-stage small air pollution degree information.

The air cleaner updates the predetermined first stage operation using the air condition and the operating condition stored in the memory 180 to generate a third stage operation (S220).

The air purifier displays the filter replacement timing through the display unit 160 using the air condition and the operating condition stored in the memory 180 (S221). The user can replace the filter 130 by looking at the filter replacement timing.

Further, the air purifier determines the air condition and mixes at least one or more fragrance stored in the fragrance storage unit 171 according to the air condition at a predetermined ratio in the fragrance mixing unit 170 to discharge the odor of the fragrance to the outside . By doing so, the user can feel the refreshing feeling by taking the fragrance of his favorite fragrance.

3 is a flowchart illustrating a method of controlling an air cleaner according to another embodiment of the present invention.

Referring to FIG. 3, the air purifier according to another embodiment of the present invention measures the temperature in the temperature sensor 101, measures the humidity in the humidity sensor 102, measures fine dust in the fine dust sensor 103 Formaldehyde is measured in the formaldehyde sensor 104, and volatile organic compounds are measured in the volatile organic compound sensor 105 (S310).

The air cleaner determines the location using temperature, humidity, fine dust information, formaldehyde information, and volatile organic compound information (S311).

The air cleaner performs a predetermined first place operation according to each place (S312)

For example, if the air cleaner determines that the humidity is relatively high and a change in temperature and humidity is high (for example, a toilet), the air cleaner may cause the fan 120 to become wet It is designed to lower the speed of the fan 120 and to purify using the ionizer 140 to perform a predetermined first place operation.

In another embodiment, if the air cleaner determines that the values of fine dust information, formaldehyde information, and volatile organic compound information are high due to surrounding smoke or the like (for example, inside the car) It is designed to be cleaned in such a manner that it operates steadily at a constant speed rather than being operated strongly, so that a predetermined first place operation is performed.

In another embodiment, if the air purifier determines that the values of fine dust information, formaldehyde information, and volatile organic compound information are reduced (for example, indoor), the air cleaner may be used for air cleaning If the state is not good, it cleans quickly, and when the value is low, it operates quietly and is designed to purify without interfering with life, so that the first place operation is performed.

The air cleaner confirms whether air pollution degree information is received from the outside through the wireless transmitting / receiving unit 110 (S313).

Upon receiving the air pollution degree information from the outside through the wireless transceiver 110, the air purifier performs a predetermined second place operation using fine dust information, formaldehyde information, volatile organic compound information, and air pollution degree information (S314 ). At this time, the predetermined second place operation may be the same as or different from the predetermined first place operation.

In addition, the air purifier determines the air condition and mixes at least one or more fragrances stored in the fragrance storage unit 171 in a predetermined ratio in the fragrance mixer 170 according to the air condition to discharge the odor of the fragrance to the outside . By doing this, not only can you drink clean air, but you can also take on the aroma of your favorite fragrance and feel refreshed.
