(142). The air purifying unit 140 may use the fan 141 to flow the ambient air to the filter unit 142 and filter the air by the filter unit 142 to purify the air. The filter unit 142 may include a combination of a plurality of HEPA filters (high-efficiency particulate air), nano filters, and activated carbon and VOC absorber filters.

The fragrance discharge unit 150 is provided to discharge the fragrance material into the surrounding air of the air purifier 100 according to the operation mode determined by the control unit 130, and includes a pump 151, a pressurized air discharge pipe 152 and a direction It may include a substance capsule 200 . The fragrance capsule 200 may be detachably mounted to the air purifier 100 . When the fragrance material capsule 200 is mounted on the air purifier 100 , the fragrance material discharge unit 150 may atomize the fragrance material stored in the fragrance material capsule 200 and discharge it to the outside of the fragrance material capsule 200 .

The communication unit 160 is connected to an external device to receive a control signal from the external device or to transmit the environmental indicator measured by the sensor unit 120 to the external device. When the communication unit 160 receives the control signal of the external device, the control unit 130 may determine the operation mode according to the control signal. In addition, the communication unit 160 directly communicates with another air purifier through a central server or short-distance communication, and may share the environmental indicator and current operation mode information. The control unit 130 may recognize a location with the other air purifier according to the environmental indicator shared through the communication unit 160 , and may determine the operation mode to synchronize the operation modes of each other.

In more detail with respect to the operation mode, the air purifier 100 according to an embodiment of the present invention may operate in the cleaning mode or the scent diffusing mode.

In the clean mode, the fan 141 is used to remove dust or odors contained in the ambient air of the air purifier 100 to suck the ambient air into the housing 110, and the inhaled ambient air is filtered through the filter unit. It may be an operation mode for filtering through 142 and then discharging to the outside of the housing 110 . In the clean mode, no fragrance is emitted. The air purifier 100 may operate in the clean mode to purify the indoor air by removing fine dust and odors contained in the indoor air of the space in which the air purifier 100 is located.

The scent diffusing mode may be an operation mode in which the scent material stored in the scent material capsule 200 is atomized and discharged to the vicinity of the housing 110 , and the fan 141 generates wind so that the discharged scent material is diffused further. The air purifier 100 operates in the scent diffusing mode to fill the space where the air purifier 100 is located with scent, so that the user can live more comfortably and comfortably in the space.

The controller 130 may control the speed of the fan according to the operation mode. For example, when the air purifier 100 is in the clean mode, the controller 130 may control the speed of the fan 141 to operate rapidly to quickly purify the air, and the air purifier 100 is in the scent diffusing mode. When the air is not sucked into the housing 110, it is possible to control the speed of the fan 141 to operate slowly so that the fragrance is blown away by the wind.

Also, the control unit 130 may determine the operation mode according to the environmental index measured by the sensor unit 120 .

In an embodiment, the controller 130 may determine the operation mode according to the dust indicator. In more detail, when the dust indicator reaches a preset indicator, the controller 130 may switch the operation mode from the clean mode to the scent diffusing mode or switch the scent diffusing mode to the clean mode. Here, the dust indicator may include a PM ₁₀ concentration measured by the PM ₁₀ sensor, a PM _2.5 concentration measured by the PM _2.5 sensor, and a PM _1.0 concentration measured by the PM _1.0 sensor. For example, if the PM ₁₀ concentration of the ambient air measured by the dust sensor 123 is 100 μg/m 3 , it is higher than a preset index of 30 μg/m 3 , so the controller 130 may determine the operation mode as the clean mode. there is. Accordingly, the control unit 130 may generate a control signal to operate the air cleaning unit 140 . While the air purifier 100 is operating in the clean mode, when the PM ₁₀ concentration of the ambient air measured by the dust sensor 123 reaches a preset index of 30 μg/m3, the controller 130 sets the operation mode to It is possible to switch to the scent diffusing mode. As the operation mode is switched to the scent diffusing mode, the control unit 130 includes a control signal for discharging the scent material and a control signal for the fan 141 to blow the scent material away. can cause In addition, when the dust index measured by the dust sensor 123 exceeds a preset index of 30 μg/m 3 while the air purifier 100 is operating in the scent diffusing mode, the controller 130 resets the operation mode to the cleaning. mode can be switched. The air purifier 100 according to an embodiment of the present invention automatically switches the operation mode according to the dust indicator measured by the sensor unit 120, so that the user can check the dust indicator and manually select the air purifier 100 There is no need to control, and when the air is purified, it automatically releases the scent, so that the user can feel that the air is purified more clearly.

In an embodiment, the controller 130 may determine the operation mode by using one or more odors or odor indicators for fragrances. In more detail, the controller 130 may determine the operation mode by using the odor indicator measured by the VOCs sensor 125 to remove odor-causing substances contained in the air. Here, the odor indicator may be the concentration of the volatile organic compound measured by the VOCs sensor 125 . For example, when the concentration of volatile organic compounds that cause odors such as benzene, toluene, benzene, phenol, and mercaptans measured by the VOCs sensor 125 exceeds the reference value, the controller 130 controls the volatile organic compounds that cause odors in the air. It may be determined that there is a compound, and the operation mode may be determined as the clean mode. When the air purifier 100 operates in the clean mode and the volatile organic compound concentration reaches the reference value or less, the controller 130 may change the operation mode from the clean mode to the scent diffusing mode to make the air more pleasant.

Also, the control unit 130 may recognize false contamination by using various sensors of the sensor unit 120 . Here, the false contamination may mean that contaminants are recognized even though there are no actual contaminants in the air. For example, as the fragrance material is discharged into the air, the atomized fragrance material is detected by the dust sensor 123 , so that the concentration of dust in the air may rapidly increase. At this time, when the control unit 130 determines the operation mode as the clean mode due to the rapidly increased dust index measured by the dust sensor 123 , the fragrance material discharged into the air may be removed. In this case, the effect of scent diffusion may be halved.

The control unit 130 may recognize false contamination by comprehensively determining environmental indicators measured by various sensors of the sensor unit 120 in order to prevent the smell diffusion effect from being halved due to such false contamination. When the control unit 130 recognizes the false contamination, it is determined that there is no pollutant in the air, and the operation mode is not switched to the clean mode, and the smell diffusion mode can be continuously maintained.

The controller 130 may identify a odor or fragrance in the air using the odor indicator measured by the VOCs sensor 125, recognize false contamination based on this, and determine the operation mode. More specifically, the sensor unit 120 collects the odor index of the volatile organic compound causing odor or the odor index when the fragrance material is discharged, and the controller 130 collects false contamination through the collected odor index data. can be recognized For example, when the air purifier 100 operates in the scent diffusing mode, the odor index measured by the VOCs sensor 125 may increase because the air purifier 100 is discharged to the fragrance material in the surrounding air. In this case, the controller 130 may determine whether the odor indicator is a odor indicator of a previously collected fragrance material. When it is determined that the odor indicator is the odor indicator of the fragrance material, even if the odor indicator exceeds a reference value, the controller 130 may recognize this as false contamination and maintain the operation mode as the fragrance diffusing mode.

The control unit 130 may determine the operation mode by recognizing false contamination based on time information from a time point when the operation mode operates in the smell diffusion mode and an environmental index measured by the sensor unit 120 . In more detail, when the air purifier 100 operates in the scent diffusing mode, the dust index measured by the dust sensor 123 may exceed a preset value due to the atomized scent material. At this time, the control unit 130 measures the time from the time of operation in the scent diffusing mode, and when the time is measured below the reference value, it recognizes that the dust indicator rises as false contamination and does not convert the operation mode to the clean mode. and can be maintained in the scent diffusing mode. In addition, the controller 130 checks the odor index of the fragrance material, and when it is determined as the previously collected odor index of the fragrance material, the control unit 130 recognizes a situation in which the dust index exceeds a preset value as false contamination, and sets the operation mode to the smell diffusion. mode can be maintained.

That is, the control unit 130 may prevent the fragrance emitted by the fragrance material discharge unit 150 from being recognized as a contaminant and not removed, so that the effect of diffusing the fragrance is not halved. Since it operates more intelligently than the conventional air purifier, the user can enjoy the effect of cleaning the air and the effect of smelling at the same time.

Also, the controller 130 may recognize false contamination by using the dust index and the humidity index. For example, when the dust index measured by the dust sensor 123 exceeds a preset value and the humidity index measured using the temperature sensor 121 and the humidity sensor 122 rises simultaneously with the dust index, the dust index rises. The situation can be perceived as false contamination. In this case, if the operation mode is the clean mode, the controller 130 may stop the clean mode or control the operation mode not to operate in the clean mode. When the dust index and the humidity index rise at the same time, atomized water droplets due to the operation of the humidifier may be detected as the dust index in many cases. Lifespan may be shortened. The control unit 130 may recognize this as false contamination and prevent shortening of the lifespan of the filter unit 142 .
