Referring to FIG. 1, an air purifier 1000 includes a plurality of filters 110, a driver 120, and a processor 130. Some of the configurations may be omitted according to the embodiment, and although not shown, appropriate configurations at a level that is obvious to a person skilled in the art may be additionally included in the air purifying apparatus 1000.

The air purifier 1000 is a device for purifying ventilation air and recirculated air for air conditioning in a building, and is mainly installed in a home or office to collect dust floating in the air, It is a device that incorporates a blower used for gas removal in parallel. The air purifying device may mean any device having a function of purifying the air. For example, the air purifier may be implemented as an apparatus for air purifying only, an air conditioner equipped with an air purifying function, a humidifier equipped with an air purifying function, or the like.

The plurality of filters 110 include various kinds of filters as a configuration for filtering out or removing contaminants, bacteria, viruses, dust, and the like in the air. The type of the filter can be classified into a dust filter, a harmful gas filter, a deodorizing filter, and a sterilizing filter depending on what is to be removed.

The plurality of filters 110 may include a filter specific to a particular hazardous material. For example, the plurality of filters 110 may include various filters such as a filter for removing formaldehyde, a filter for removing oil mist, a filter for sterilization / allergen removal, a filter for deodorization (ammonia, hydrogen sulfide, etc.), and a dust filter.

The filter may be classified into a dust collection system, an absorption system, a catalytic system, and the like depending on the removal system, and the plurality of filters 110 may include filters of various systems.

The above-described embodiments are merely examples, and a more various types of filters may be included in the plurality of filters 110 depending on the purpose of use of the air purifier 1000. [

The plurality of filters 110 can be individually attached and detached, so that the filters can be configured and used by a user in a desired combination of types. The plurality of filters 110 may be fabricated in the form of a module or a cartridge, and may have the same specifications.

According to the present disclosure, a plurality of filters 110 can be individually moved within the air purifier 1000. By implementing the plurality of filters 110 individually so as to be movable individually, only necessary filters among the plurality of filters 110 can be used for air cleaning. That is, only necessary filters may be disposed in the air passage of the air purifier 1000, and other filters may be disposed outside the air passage according to circumstances. The air passage means a passage through which air required to be cleaned flows in the air purifying apparatus 1000. Only necessary filters are disposed in the air passage and the fan is rotated to prevent air from passing through the remaining filters. The direction of the air passage in the air purifying apparatus 1000 may be always constant or the direction of the air passage may be changed by controlling the rotation of the fan in the air purifying apparatus 1000. [

According to one embodiment, the plurality of filters 110 can be individually moved in the air purifying device 1000, for example, up and down, right and left, diagonal, and the like. According to another embodiment, the plurality of filters 110 are movable along a circular path provided in the air purification apparatus 1000. According to yet another embodiment, the plurality of filters 110 are collapsible and unfoldable in the air passageway so that, in the deployed state, they can be folded into the air passageway and out of the air passageway.

The plurality of filters 110 may all be configured to have the same motion, or may be configured to have different motions. In the latter case, for example, some filters among the plurality of filters 110 can be moved up and down, and other filters can be folded and unfolded.

The driving unit 120 is configured to move the plurality of filters 110 individually. According to one embodiment, the driving unit 120 can move the plurality of filters 110 individually up and down or right and left. According to another embodiment, the driving unit 120 can move the plurality of filters 110 individually along the circular path in the air purifier 1000. [ According to another embodiment, the driving unit 120 may fold or unfold a plurality of collapsible and expandable filters 110 individually. According to another embodiment, the driving unit 120 may fold or unfold a plurality of collapsible and expandable filters 110 individually.

When some filters of the plurality of filters 110 move in a first movement (e.g., a left-right movement) and some of the filters move in a second movement (e.g., a vertical movement), the driving unit 120 moves the filter Can be driven.

The driver 120 includes an actuator that provides power to move the filter. An actuator is a device that generates energy by receiving energy from the outside. The actuator may comprise an electric motor, an electromagnet, a cylinder or motor operated by pneumatic or hydraulic pressure.

The driving unit 120 can implement the above-described various filter movements through various combinations of actuators, gears, chains, rollers, and the like. For example, the driving unit 120 may include a motor such as a servo actuator, a stepper motor, a gear, a connecting chain, and the like. According to one embodiment, a chain is connected to each of the plurality of filters 110, and a gear connected to the motor is rotated in contact with the chain, so that the plurality of filters 110 can move.

The processor 130 is a configuration for controlling the overall operation of the air cleaning apparatus 1000. [ The processor 130 may be implemented as a CPU (or a DSP or MPU), an application specific integrated circuit (ASIC), a SoC, a MICOM (MICRO COMPUTER), or the like. The processor 130 may drive an operating system or an application program to control a plurality of hardware or software components connected to the processor 130, and may perform various data processing and operations.

The processor 130 may control the driving unit 120 to move the plurality of filters 110 individually. According to one embodiment, the processor 130 may control the driving unit 120 such that at least one of the plurality of filters 110 is disposed in the air passage in the air purifying apparatus 1000 according to the air condition.

The processor 130 can control air to pass through the air passage in a situation where the at least one filter is disposed in the air passage and the remaining filters are disposed outside the air passage. For example, the processor 130 may control the fan (not shown) in the air purifier 1000 to rotate so that air can pass through the air passageway.

The air purifier 1000 may include a sensor for obtaining a sensing value for determining the air condition. The sensor may be, for example, a gas sensor and / or a dust sensor.

For example, a heater is used in a dust sensor to induce forced convection to flow particles. In this case, a method of measuring the amount of light detected by absorption, reflection, scattering or the like using a light source, Type sensor can be used.

One or more gas sensors may be used. There are various types of gas sensors depending on the method of sensing the gas. Examples of the gas sensing method include a contact combustion method, an electrochemical method (for example, a solution conduction method, a static electric potential method, a diaphragm electrode method) (Hydrogen ionization method, thermal conduction method, contact combustion method, semiconductor method), reaction coloring method, solution conductivity method, solid electrolyte method, Gas chromatography and the like.

Here, the semiconductor system uses a phenomenon in which the conductivity increases when a reducing gas adsorbs to a semiconductor of a metal oxide (N-type center). In a contact combustion system, a combustible gas is burned by a catalyst such as platinum, The concentration of the reaction gas is measured by ascertaining the increase in the electrical resistance of the platinum wire. The electrochemical method is a method in which the redox reaction between the positive electrode and the negative electrode is performed in an electrolyte (for example, Conc-H ₂ SO ₄ ) The method of measuring the gas concentration by measuring the resistance value of the platinum wire and the thermistor by using the thermal conductivity determined by the surrounding gas is a method of measuring the concentration of the gas by sensing the change of the current value generated by the gas , The optical interference method is a method of measuring the concentration of gas by using an interference fringe due to a difference in refractive index between air and target gas, The coloring method is a method of reacting a gas with a liquid or a solid to develop a color, and measuring the degree of coloring optically to measure the concentration of the gas. The solution conductivity method measures the change in the conductivity of the solution by absorbing the measurement gas into an appropriate solution, The solid electrolyte system is a system for measuring the concentration of gas by using the electromotive force generated by the partial pressure difference when a difference in oxygen partial pressure between both sides occurs through the solid electrolyte having oxygen ion conductivity.

According to an embodiment of the present disclosure, a gas sensor may be provided for each gas to be measured. For example, the air purification apparatus 1000 may include a plurality of gas sensors such as a first gas sensor for ammonia sensing, a second gas sensor for formaldehyde sensing, a third gas sensor for toluene sensing, and the like. The processor 130 may determine the type of gas present in the air based on the sensed values of each of the plurality of gas sensors.

According to another embodiment, the air purification apparatus 1000 includes a plurality of gas sensors of different kinds, and the ratio of the sensed values of the plurality of different types of gas sensors is different for each gas, The type can be judged.

Here, the plural gas sensors are different kinds, which means that the gas sensing method is different. For example, one of the plurality of gas sensors may be a gas sensor using a contact combustion method and the other may be a gas sensor using a thermal conductivity method.

Alternatively, the meaning of the plurality of gas sensors being different from each other means that the gas sensing method is the same (for example, a plurality of gas sensors use the same semiconductor method) but there is a difference in the manufacturing process of the gas sensor . The case where there is a difference in the manufacturing process of the sensor includes, for example, the shape of the sensor is different, the constituent material of the sensor is different, the manufacturing site of the sensor is different, or the manufacturing date, can do.

Even if a plurality of gas sensors having different gas sensing methods or sensors sensing gas in the same manner are used, a different sensing value can be obtained for each gas sensor in the same environment by using a plurality of gas sensors having different manufacturing processes.

According to the present embodiment, when the air purifier 1000 reacts with various gases, information on sensing values of a plurality of gas sensors is stored in advance. For example, when a plurality of gas sensors react with formaldehyde, information on the sensing value, information on sensing values when a plurality of gas sensors react with ammonia, information on sensing values when a plurality of gas sensors react with toluene, etc. May be stored in the air cleaning apparatus 1000 in advance. When the sensing value is obtained through the plurality of gas sensors, the processor 130 can determine the type of gas by comparing the information with the previously stored information. For example, when the air purification apparatus 1000 includes a first gas sensor and a second gas sensor, when the reaction with formaldehyde is performed, information that the ratio of the sensing value of the first gas sensor to the sensing value of the second gas sensor is 1: 2 Assume that it is stored in advance. In this case, when the ratio of the sensing value of the first gas sensor and the sensing value of the second gas obtained when the first gas sensor and the second gas sensor react with the unknown gas is 1: 2, Can be judged to be formaldehyde.

According to the above-described embodiment, it is possible to determine the type of gas by using a plurality of gas sensors. The concentration of the gas can also be determined based on the magnitude of the sensing value.

According to another embodiment of the present disclosure, instead of using a plurality of gas sensors as described above, it is possible to use one semiconductor gas sensor having different reaction characteristics with respect to gas depending on the temperature. That is, one semiconductor gas sensor capable of operating at various temperatures can replace a plurality of different types of semiconductor gas sensors. According to the present embodiment, the processor 130 may control the temperature of the heater present in the semiconductor gas sensor.

The processor 130 controls the driving unit 130 so that at least one of the plurality of filters 110 is disposed in the air passage in the air purifying apparatus 1000 according to the air condition determined based on the output values of the dust sensor and / 120).

According to one embodiment, the processor 130 determines the type of gas based on the sensing value of the at least one gas sensor of the air purifier 1000, and determines the type of the gas among the plurality of filters 110 The driving unit 120 can be controlled so that a corresponding filter is disposed in the air passage.

The detachable sensor 170 can communicate with the air cleaning apparatus 1000 with its own communication unit to transmit the sensed value to the air cleaning apparatus 1000.

The memory 140 may include, for example, an internal memory or an external memory. The internal memory may be, for example, a volatile memory (e.g., dynamic RAM, SRAM, or synchronous dynamic RAM (SDRAM)), a non-volatile memory (e.g., an OTPROM time programmable ROM (ROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (such as NAND flash or NOR flash) Or a solid state drive (SSD).

The external memory may be a flash drive such as a compact flash (CF), a secure digital (SD), a micro secure digital (SD), a mini secure digital (SD), an extreme digital A multi-media card (MMC), a memory stick, or the like. The external memory may be functionally and / or physically connected to the air purifier 1000 through various interfaces.

The memory 140 may store computer executable instructions and the processor 130 may perform functions of the various embodiments described in this disclosure by executing computer executable instructions stored in the memory 140 .

The memory 140 may store information on criteria for determining an air condition. For example, if a specific contaminant is present at a specific concentration or higher, reference information for determining that the air condition is contaminated may be stored, and memory 140 may store information about which kind of gas corresponds to which filter . The processor 130 determines the air condition based on the sensing value obtained through the sensor 170 and the information stored in the memory 140 to determine which of the plurality of filters 110 is to be placed in the air passage . For example, when it is determined that the gas type is ammonia or hydrogen sulfide based on the sensing value obtained through the sensor 170, the processor 130 extracts, from information stored in the memory 140, a filter corresponding to ammonia or hydrogen sulfide, And controls the driving unit 120 so that the deodorization filter is disposed in the air passage.

To this end, the memory 140 may store information on the lifetime of each of the plurality of filters 110 and usage history information on each of the plurality of filters 110. For example, the memory 140 may store information on the history of each of the plurality of filters 110 disposed in the air passage. The memory 140 may store information about a period of time allocated to the plurality of filters 110 in the air passage and the processor 130 may increase the period of use of the filter when an event occurs in which the filter is disposed in the air passage The information in the memory 140 can be updated. The processor 130 may then provide the user with a notification of filter replacement based on the information about the filter usage history stored in the memory 140. [

The memory 140 may store information as to how much each of the plurality of filters 110 was disposed in the air passage as described above, and more particularly, when the filter is disposed in the air passage, You can also store information about whether they were placed in order. That is, as the air passage is disposed at the front side, the contamination sources are more likely to be in contact with each other, so that the service life can be quickly reduced. For example, referring to FIGS. 4 to 5, in the case of FIG. 4, the third dust filter 110e is arranged third in the air passage, and in the case of FIG. 5, the third dust filter 110e And is disposed fourth in the air passage. The life of the third dust filter 110e may be shortened when the third dust filter 110e is used as in the case of Fig. 4, as compared with the case where the third dust filter 110e is used as in Fig. 5 . It is possible to determine the remaining life of each of the filters by taking into consideration information on the arrangement order in the air passage as described above, and to provide the user with a more accurate notification of the filter replacement time based on the determination.

Instead of receiving the user's operation through the input unit 220, a signal for user's operation in the external device may be received through the communication unit 160. [

23 is a view for explaining a method for controlling the air purification apparatus 1000 according to an embodiment of the present disclosure.

Referring to FIG. 23, the air purifier 1000 can perform communication with the external device 300 through the communication unit 160. The external device 300 may be an electronic device such as a smart phone, a tablet PC, or the like.

For example, in the external device 300, an application for controlling the air purifier 1000 may be executed. These applications can be distributed online through application stores (eg PlayStore ™). The external device 300 can be provided with a UI screen 310 for controlling the air purifier 1000, for example, by executing the application in the external device 300. [ The UI screen 310 may include information on the air condition 311 sensed through the sensor 170 of the air purifier 1000, a driving mode selection menu 313, and the like. For example, the user can select one of a cooking mode, a cleaning mode, a ventilation mode, and the like through the UI screen 310. When a signal corresponding to the user's selection is transmitted to the air purifier 1000, The mobile station 1000 may operate in a mode corresponding to the received signal.

According to another embodiment of the present disclosure, the external device 300 can control the air purifier 1000 as if it were in communication with the air purifier 1000 using a messenger program. For example, the air purifier 1000 and the external device 300 can exchange conversation messages through the message server. The air purifier 1000 transmits a conversation message including information on the current operation mode, information on the air condition, information on the on / off state, information for notifying the replacement of the filter, And the message server can transmit the message to the external device 300. [ The external device 300 may execute a messenger program and display a conversation message received from the air purifier 1000 through the message server. That is, a chat screen can be configured as if the air purifier 1000 is a chat partner. When the user inputs text for controlling the air purifier 1000 on the chat screen, the text is displayed on the chat screen, and a chat message including control information corresponding to the input text is transmitted to the air purifier 1000). The air cleaning apparatus 1000 may perform an air cleaning operation corresponding to the control information included in the received conversation message. For example, if the user inputs the text " operate in the cooking mode " through the chat screen provided through the external device 300, the air purifier 1000 can operate in the cooking mode.

According to another embodiment of the present disclosure, the external device 300 capable of communicating with the air purification apparatus 1000 is not simply an application, but an artificial intelligence agent is an artificial intelligence (AI) based service , Secretarial services, search services, etc.). The artificial intelligence agent can be executed by a conventional general purpose processor or a separate AI dedicated processor. The artificial intelligence agent may provide an interactive service such as a chatbot, and may provide an alert on the messenger about the status of the air purifier 1000, such as when to replace the filter. In addition, a UI screen for subsequent actions according to the state of the air purifier 1000 can be provided. For example, when the filter in the air purification apparatus 1000 is to be replaced, a UI screen including a link to a website for purchasing a filter may be provided. Depending on the state of the air determined through the sensor 170 A UI screen for selecting the operation mode of the recommended air purifier 1000, and the like can be provided. Meanwhile, such an artificial intelligent agent may be installed in the air purification apparatus 1000. [

According to one embodiment of the present disclosure, the processor 130 may include at least one of a data learning unit that uses an artificial intelligence algorithm to learn an artificial intelligence model and a data recognition unit that uses an artificial intelligence model.

The data learning unit may generate or learn a data recognition model so as to have a criterion for determining in which mode the air purifier 1000 operates. The data learning unit uses, for example, data such as a sensing value obtained from the sensor 170 or information received from another device (for example, a cleaner, a kitchen appliance, or a smartphone) capable of communicating with the air purification apparatus 1000 as learning data So that a data recognition model can be generated or learned.

The data recognition unit can determine the operation mode of the air purification apparatus 1000 using the learned data recognition model. The data recognition unit can determine the operation mode of the air purifier 1000 based on the predetermined data by acquiring predetermined data according to a preset reference and applying the obtained data to the data recognition model as an input value. Further, the output value obtained by applying predetermined data to the data recognition model can be used to update the data recognition model.

According to one embodiment of the present disclosure, a sensing value obtained from a sensor such as a gas sensor, a dust sensor, an environmental sensor (e.g., a room sensor, a motion sensor, a noise sensor, The operation mode of the air purifier 1000 can be determined by applying data such as state information received from the air conditioner 1000 to the data recognition model. The air purifier 1000 can operate according to the determined operation mode.

According to an embodiment of the present disclosure, the autonomic operation, monitoring, and automatic on / off functions of the air purifier 1000 can be performed according to the user profile and the usage base by using the artificial intelligence system.

For example, the processor 130 may collect user movement information and user movement information collected through a user terminal device such as a smart phone communicating with the sensor 170 and the air purification apparatus 1000 provided in the air purification apparatus 1000 The user's profile information related to the life pattern of the user can be generated by applying to the data recognition model and the operation mode of the air purifier 1000 can be determined based on the profile information of the user. For example, if it is determined that the current time is the sleeping time based on the profile information of the user, the air conditioner 1000 can operate in the minimum clean mode so that the noise is minimized.

Meanwhile, the user profile information used to determine the operation mode of the air purification apparatus 1000 may include information on the pollutant source of interest to the user, information on the operation mode frequently used by the user, and the like. So that the operation mode of the air purifier 1000 reflecting the user preference can be determined.

As another example, the operation mode of the air purifier 1000 can be determined in consideration of whether the user is indoors or indoor. That is, for example, it is possible to prevent the air cleaner 1000 from operating unnecessarily while the user is not present. For example, the processor 130 can determine the operation mode by applying the sensing value obtained from the gas sensor, the dust sensor, etc., and the sensing value obtained from the sensor such as the room sensor or the motion sensor to the data recognition model.

As another example, the processor 130 may perform automatic on / off control of the air purifier 1000 or automatic idle mode / active mode switching based on the sensing value obtained from the sensor. For example, even when the air purifier 1000 is in the standby mode, the sensor 170 may be activated, and when it is determined that air purification is necessary based on the sensing value obtained from the sensor 170, The air purifier 1000 can be switched to the active mode.

According to one embodiment of the present disclosure, when status information is received from an external device via the communication unit 170, the processor 130 may automatically perform an air cleaning operation associated with the received status information.

For example, in a situation where a large amount of dust may be generated, for example, in a situation where the user uses the cleaner, the cleaner may transmit status information indicating that cleaning has been performed to the air cleaner 1000. The processor 130 determines the operation mode of the air cleaning apparatus 1000 to be the automatic dust removal mode by applying the status information received from the cleaner to the data recognition model and if the air cleaning apparatus 1000 is in the idle mode The air cleaning apparatus 1000 can be switched to the active mode and the driving unit 120 can be controlled so that the dust filter is disposed in the air passage.

As another example, in a situation where a large amount of smell may occur, for example, when the user is cooking using the electric range, the electric range may transmit status information indicating that cooking has been performed to the air cleaning apparatus 1000. The processor 130 determines the operation mode of the air cleaning apparatus 1000 to be the automatic deodorizing mode by applying the state information received from the electric range to the data recognition model and if the air cleaning apparatus 1000 is in the standby mode, It is possible to control the driving unit 120 to switch the air conditioner 1000 to the active mode and place the deodorizing filter in the air passage.

According to another embodiment, by applying the sensed value of the sensor 170 to the data recognition model as input data, an optimized mode for contaminant removal present in the air can be selected. For example, the processor 130 may apply a sensing value obtained through a sensor such as a gas sensor, a dust sensor, etc. to a data recognition model to identify a major source of contamination and to identify the level of contamination. Based on this, the type of filter and the number of filters for the shortest time air cleaning can be determined, and the determined type and number of filters can be arranged in the air passage.

Meanwhile, although the artificial intelligence system is described as being installed in the air purifier 1000 in the above-described embodiment, it is also possible to control the air purifier 1000 by an external server mounted on an external server.

21 is a flowchart for explaining a control method of an air purifying apparatus including a driving unit for moving a plurality of filters individually according to an embodiment of the present disclosure. The flow chart shown in Fig. 21 can be configured with the operations to be processed in the above-described air purifying apparatus 1000. Fig. Therefore, even if omitted from the following description, the description relating to the air cleaning apparatus 1000 described above can be applied to the flowchart shown in FIG.
