The water tank (110) may be formed of stainless steel.

[0087] When the heating source (130) is operated, the lower part (111) of the water tank (110) is heated, and the water inside the water tank (110) is heated to generate steam.

[0088] The humidification device (100) may include an auxiliary case (115). The auxiliary case (115) may be formed in a cylindrical shape and arranged to surround the water tank (110), and the upper and lower parts of the auxiliary case (115) may be open.

[0090] At least a portion of the heating source (130) may be accommodated below the protrusion (122) of the case (121). The protrusion (122) of the case (121) may be formed with a shape and size corresponding to the heating source (130). For example, if the heating source (130) is circular, the diameter of the protrusion (122) of the case (121) may be formed to have a diameter equal to or larger than the diameter of the heating source (130).

[0091] The water tank (110) may include a protrusion (112). The protrusion (112) of the water tank (110) may protrude upward from the lower part (111) of the water tank (110) to correspond to the protrusion (122) of the case (121). When viewed from below the water tank (110), the protrusion (112) of the water tank (110) may appear to be sunken in the lower part (111) of the water tank (110).

[0092] The protrusion (122) of the case (121) can be received in the protrusion (112) of the water tank (110). The diameter of the protrusion (112) of the water tank (110) can be formed to be larger than the diameter of the protrusion (122) of the case (121). The protrusion (112) of the water tank (110) may be referred to as the first protrusion, and the protrusion (122) of the case (121) may be referred to as the second protrusion.

[0093] By providing a protrusion (112) of the water tank (110) and a protrusion (122) of the case (121), the contact area between the heating source (130) and the lower part (111) of the water tank (110) can be increased. Therefore, the heating efficiency of the water by the heating source (130) can be improved.

The lower portion (141a) of the first portion (141) may have a conical shape.

[0097] The lower part (141a) of the first part (141) can accommodate the protrusion (112) of the lower part (111) of the water tank (110). The diameter and / or size of the lower part (141a) of the first part (141) can be made larger than the diameter and / or size of the protrusion (112). The first part (141) of the partition member (140) can cover the protrusion (112) formed in the lower part (111) of the water tank (110). The position of the partition member (140) can be stably maintained by the first part (141) of the partition member (140) and the protrusion (112) of the water tank (110). In addition, water contained in the inner space of the first part (141) can be intensively heated by the heating source (130), and steam can be rapidly generated.

[0098] The lower part (141a) of the first part (141) may come into contact with the lower part (111) of the water tank (110). The liquid contained in the steam generation area (S1), which is the inner area of ​​the partition member (140), and the liquid contained in the storage area (S2), which is the outer area of ​​the partition member (140), may not freely mix with each other.

[0099] The contact surface between the lower part (141a) of the first part (141) and the lower part (111) of the water tank (110) may not be sealed. There may be a gap between the lower part (141a) of the first part (141) and the lower part (111) of the water tank (110), and water may move through the gap. When the water level inside the partition member (140) becomes lower than the water level outside the partition member (140) as the heating source (130) operates, the water contained in the storage area (S2) may move to the steam generation area (S1).

[0100] The cross-sectional area of ​​the partition member (140) may decrease from the lower part (141a) to the upper part (141b) of the first part (141). In other words, the surface of the first part (141) may have a structure inclined with respect to a vertical or horizontal line. The vertical line extending from the inner surface of the second part (142) and the inner surface of the first part (141) may be formed to have a first angle (a1). For example, the first angle (a1) may be an angle greater than 45°.

[0101] The first part (141) may be formed in a flat shape to minimize internal volume while covering the heating area of ​​the lower part (111) of the water tank (110). For example, the ratio (h / R) of the height (h) of the first part (141) to the radius (R) of the lower part (141a) of the first part (141) may be 1.0 or less. Since the volume of water contained in the first part (141) is relatively small, the time required from the start of operation of the humidification device (100) until steam is generated can be significantly reduced, and the noise generated when heating water can be reduced. The smaller the ratio (h / R) of the height (h) of the first part (141) to the radius (R) of the lower part (141a) of the first part (141), the less time required for steam generation can be reduced.

[0102] The second part (142) of the partition member (140) may extend upward from the upper part (141b) of the first part (141). The lower end of the second part (142) is connected to the first part (141), and the upper end of the second part (142) may be open. With the partition member (140) placed inside the water tank (110), the position of the upper end of the second part (142) may be higher than the maximum water level of the water tank (110). The second part (142) may guide water vapor generated in the first part (141) upward.

[0103] The second part (142) of the partition member (140) may be provided in a cylindrical shape. When the second part (142) is cut in a vertical direction, both sides of the second part (142) may be parallel. In other words, the angle formed by the inner surface of the second part (142) and the vertical direction may be 0 degrees.

[0104] The inner diameter (D) of the second part (142) can be selected from a range of 40 mm or more and 60 mm or less. For example, if the inner diameter (D) of the second part (142) is 50 mm, water overflow to the outside of the second part (142) may not occur even if the ratio (h / R) of the height (h) of the first part (141) to the radius (R) of the lower part (141a) of the first part (141) is formed to 0.25.

[0105] As the inner diameter (D) of the second part (142) becomes smaller, the volume of the steam generation area (S1) decreases, so the time required to generate steam can be reduced. However, as the inner diameter (D) of the second part (142) becomes smaller, the water that is actively boiling in the lower part (111) of the water tank (110) can overflow more to the top of the second part (142).

[0106] The partition member (140) may be formed from a metal material with good corrosion resistance. For example, the partition member (140) may be formed from stainless steel. The material of the partition member (140) is not limited to metal and may also be formed from a heat-resistant plastic material or a ceramic material.

[0107] FIG. 11 shows an enlarged view of the backflow prevention valve illustrated in FIG. 2.

[0108] Referring to FIG. 11, the steam discharge cap (151) may include a steam outlet (151a). With the cover (150) coupled to the water tank (110), the steam discharge cap (151) may be coupled to a second part (142) of the partition member (140). Steam generated in the steam generation area (S1) of the partition member (140) may be discharged to the steam outlet (151a) through the second part (142) of the partition member (140).

[0109] The steam discharge channel (152) illustrated in FIG. 2 is provided between the steam outlet (151a) and the second discharge port (101) to connect the steam outlet (151a) and the second discharge port (101). Steam generated within the partition member (140) can pass through the steam outlet (151a) and the steam discharge channel (152) and then be discharged to the outside of the humidifying air purifier (1) through the second discharge port (101).

[0110] A backflow prevention valve (153) may be provided in the steam discharge cap (151). The backflow prevention valve (153) may be positioned below the steam discharge port (151a). In the event that the water tank (110) is overturned, the backflow prevention valve (153) may prevent water within the partition member (140) from being discharged to the outside through the steam discharge path (152). The backflow prevention valve (153) may include a valve body (154) and an opening / closing member (155).

[0111] A valve hole (1541) that is open in the vertical direction may be formed in the center of the valve body (154). An opening / closing member (155) may move in the vertical direction along the valve hole (1541). The inlet (1541a) of the valve hole (1541) may face the inner space of the second part (142), and the outlet (1541b) of the valve hole (1541) may face the steam outlet (151a).

[0112] Additionally, the valve body (154) may include a plurality of through holes (1542). The plurality of through holes (1542) may be formed around the valve hole (1541). The plurality of through holes (1542) may be arranged along the circumferential direction of the valve body (154). The plurality of through holes (1542) may connect the inner space of the second part (142) with the outlet (1541b) of the valve hole (1541). Steam generated in the steam generation area (S1) of the partition member (140) may be discharged to the steam outlet (151a) through the plurality of through holes (1542) and the outlet (1541b) of the valve hole (1541).

[0113] Figure 12 illustrates an enlarged view of the state of the backflow prevention valve when the humidifying air purifier is in a state of conduction.

[0114] Referring to FIG. 12, the water tank (110) may be tilted during the separation process of the water tank (110) or when the humidifying air purifier (1) is tilted. When the water tank (110) is tilted, the opening / closing member (155) moves toward the steam outlet (151a) and can close the steam outlet (151a). By closing the steam outlet (151a) with the opening / closing member (155), the water contained within the partition member (140) can be prevented from leaking out of the humidifying air purifier (1) through the steam outlet (151a).

[0115] FIG. 13 illustrates a partition member according to various embodiments.

[0116] Referring to FIG. 13, the cross-sectional area of ​​the first part (141) of the partition member (140) may decrease towards the top. The vertical line with respect to the ground and the inner surface of the first part (141) may be formed to have a first angle (a1).

[0117] The cross-sectional area of ​​the second part (142) may also decrease towards the top. The vertical line to the ground and the inner surface of the second part (142) may be formed to form a second angle (a2). The second part (142) may be formed to have a gentle slope from the bottom toward the top. The second angle (a2) may be formed to be smaller than the first angle (a1).

[0118] FIG. 14 illustrates a partition member according to various embodiments.

[0119] Referring to FIG. 14, the partition member (140) may include a first part (141), a second part (142), and a third part (143). The cross-sectional area of ​​the first part (141) may decrease towards the top. The second part (142) may be provided in a cylindrical shape. The third part (143) may extend from the second part (142) and be located above the second part (142). The cross-sectional area of ​​the third part (143) may increase from the bottom to the top.

[0120] FIG. 15 is a control block diagram of a humidifying air purifier according to one embodiment.

[0121] Referring to FIG. 15, the humidifying air purifier (1) may include a blower fan (30), a heating source (130), a first temperature sensor (210), a second temperature sensor (220), and a processor (420). Additionally, the humidifying air purifier (1) may include a dust collector (20), a user interface (300), a communication circuit (330), and a memory (410).

[0122] The memory (410) can store programs and data for controlling the operation of the humidifier air purifier (1). The processor (420) is electrically connected to various components of the humidifier air purifier (1) and can control each of them.

[0123] The processor (420) is hardware and may include logic circuits and arithmetic circuits. The processor (420) can control electrically connected components of the humidifying air purifier (1) using programs, instructions, and / or data stored in memory (410) for the operation of the humidifying air purifier (1). The processor (420) and memory (410) may be implemented as separate chips or as a single chip. Additionally, one or more processors and one or more memories may be provided.

[0124] The processor (420) may include one or more of a CPU (Central Processing Unit), GPU (Graphics Processing Unit), APU (Accelerated Processing Unit), MIC (Many Integrated Core), DSP (Digital Signal Processor), NPU (Neural Processing Unit), hardware accelerator, or machine learning accelerator.

[0125] The memory (410) can store programs, applications, instructions, and / or data for the operation of the humidifying air purifier (1), and can store data generated by the processor (420). For example, the memory (410) can store programs, applications, instructions, and / or data for performing purification operation and humidification operation.

[0126] The memory (410) may include non-volatile memory such as ROM (Read Only Memory) or flash memory for storing data for a long period of time. The memory (410) may include volatile memory such as S-RAM (Static Random Access Memory, S-RAM) or D-RAM (Dynamic Random Access Memory) for storing data temporarily.

[0127] Depending on the purpose of data storage, the memory (410) may be implemented in the form of a memory embedded in the humidifier air purifier (1) or in the form of a memory that can be attached to or detached from the humidifier air purifier (1). For example, data for operating the humidifier air purifier (1) may be stored in the memory embedded in the humidifier air purifier (1). Data for the expansion function of the humidifier air purifier (1) may be stored in the memory that can be inserted into or removed from the humidifier air purifier (1).

[0128] The blower fan (30) can generate airflow by rotating. When the blower fan (30) operates, air can move from the inlet (11) of the humidifying air purifier (1) to the first outlet (12) and the second outlet (101). The processor (420) can control the blower fan (30) and adjust the rotation speed of the blower fan (30).

[0129] The dust collector (20) can purify the air sucked in through the inlet (11). For example, the dust collector (20) can collect aerosols in the air. The dust collector (20) may include an electrostatic precipitator that generates ions to charge the aerosols and collects the charged aerosols. The processor (420) can control the operation of the dust collector (20). The processor (420) can regulate the power supplied to the dust collector (20).

[0130] A heating source (130) can heat water stored in a water tank (110). The heating source (130) may include a heater that generates heat and / or an induction heating coil that generates a magnetic field. The heater can heat the water by transferring heat to the water tank (110). The induction heating coil can apply an induction current to the water tank (110) so that the water tank (110) itself generates heat.

[0131] When an induction heating coil is used, the time required to heat the water can be shortened compared to when a heater is used. Additionally, since the induction heating coil heats the entire lower portion (111) of the water tank (110), the heat density, which represents the amount of heat generated per unit area, can be reduced. If the heat density is reduced, the noise generated during the heating of the water can be reduced.

[0132] The processor (420) can adjust the power level of the heating source (130). As the power level of the heating source (130) increases, the heat transferred to the water contained in the water tank (110) can increase. For example, the processor (420) can set the power level of the heating source (130) to the maximum at the start of humidification operation and lower the power level of the heating source (130) when steam is generated.

[0133] The first temperature sensor (210) can detect a first temperature of the air sucked in through the inlet (11). The first temperature sensor (210) can be placed at the inlet (11) or at a location adjacent to the inlet (11). The first temperature sensor (210) can transmit an electrical signal corresponding to the detected first temperature of the air to the processor (420). The processor (420) can identify the first temperature of the air sucked in through the inlet (11) based on the signal transmitted from the first temperature sensor (210). The processor (420) can identify the first temperature of the air at predetermined time intervals. Generally, the humidifying air purifier (1) can be placed in an indoor space, and the first temperature can represent the indoor temperature.

[0134] The second temperature sensor (220) can detect a second temperature of mixed air containing water vapor discharged through the second discharge port (101). The second temperature sensor (220) can be placed at the second discharge port (101). The second temperature sensor (220) can transmit an electrical signal corresponding to the detected second temperature of the mixed air to the processor (420). The processor (420) can identify the second temperature of the mixed air discharged through the second discharge port (101) based on the signal transmitted from the second temperature sensor (220). The processor (420) can identify the second temperature of the mixed air at predetermined time intervals.

[0135] The user interface (300) can receive user input and output various information. The user interface (300) may include an input interface (310) and an output interface (320). The user can interact with the humidifying air purifier (1) through the user interface (300). The user interface (300) may be provided at various locations on the housing (10).

[0136] The input interface (310) can acquire user input. The input interface (310) can transmit an electrical signal corresponding to the user input to the processor (420). The user input may include various commands. For example, the input interface (310) may acquire a power-on command, a power-off command, an operation mode setting command, a wind direction control command, a wind speed control command, and / or a target temperature setting command. The user input may also be acquired from a user device (e.g., a mobile device, a smartphone). The processor (420) can control the humidifier air purifier (1) based on the user input acquired through the input interface (310).

[0137] The input interface (310) may include various buttons. For example, the input interface (310) may include a power button for turning the humidifier air purifier (1) on or off, an operation mode setting button for setting the operation mode of the humidifier air purifier (1), an airflow control button for adjusting the airflow direction, an airflow speed control button for adjusting the airflow speed, and / or a temperature button for setting the target temperature. Each button may include a visual indicator (e.g., text, image, icon, etc.) that can indicate its function.

[0138] The 'button' can be implemented as a UI element (User Interface Element), tact switch, push switch, slide switch, toggle switch, micro switch, touch switch, touchpad and / or touchscreen. Additionally, the button can be replaced with a jog dial or a microphone.

[0139] The output interface (320) can be controlled by the processor (420) to output various information related to the operation of the humidifying air purifier (1). For example, the output interface (320) can output various information such as the operating mode, wind direction, wind speed, air pollution level, humidity, temperature, and operating time of the humidifying air purifier (1). The output interface (320) can output visual information and / or auditory information.

[0140] The output interface (320) may include at least one of a liquid crystal display (LCD) panel, an indicator, a light-emitting diode (LED) panel, an organic light-emitting diode (OLED) panel, a micro LED panel, and a speaker.

[0141] The output interface (320) can display information entered by the user or information provided to the user on various screens. The output interface (320) can display information related to the operation of the humidifying air purifier (1) as at least one of an image and text. The output interface can display a graphic user interface (GUI) that enables control of the humidifying air purifier (1).

[0142] The communication circuit (330) can perform wired communication and / or wireless communication with an external device (e.g., user device, server, home appliance, etc.). The communication circuit (330) can be controlled to transmit data to an external device or receive data from an external device.

[0143] The communication circuit (330) may include at least one of a short-range communication circuit or a long-range communication circuit. The communication circuit (330) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel, and the performance of communication through the established communication channel. The communication circuit (330) may include a wireless communication circuit (e.g., a cellular communication circuit, a short-range wireless communication circuit, or a GNSS (global navigation satellite system) communication circuit) and / or a wired communication circuit (e.g., a LAN (local area network) communication circuit, or a power line communication circuit).

[0144] The communication circuit (330) can communicate with an external device through a short-range communication network (e.g., Bluetooth, WiFi (wireless fidelity) direct or IrDA (infrared data association)) or a long-range communication network (e.g., legacy cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., LAN or WAN).

[0145] A short-range wireless communication module may include, but is not limited to, a Bluetooth communication circuit, a BLE (Bluetooth Low Energy) communication circuit, a Near Field Communication module, a WLAN (Wi-Fi) communication circuit, a Zigbee communication circuit, an infrared (IrDA, infrared Data Association) communication circuit, a WFD (Wi-Fi Direct) communication circuit, an UWB (ultrawideband) communication circuit, an Ant+ communication circuit, and a microwave (uWave) communication circuit.

[0146] The remote communication circuit may include a communication circuit that performs various types of remote communication and may include a mobile communication interface. The mobile communication interface transmits and receives wireless signals with at least one of a base station, an external terminal, and a server on a mobile communication network.

[0147] In addition, the communication circuit (330) can communicate with an external device through an access point (AP).

[0148] The control configuration of the humidifying air purifier (1) is not limited to that of the exemplified configuration. The humidifying air purifier (1) may include additional configurations other than those of the exemplified configurations, or may not include some of the exemplified configurations. For example, the humidifying air purifier (1) may further include a temperature sensor for detecting the temperature of water stored in the water tank (110), a humidity sensor for detecting the humidity of the air, and / or a pollution sensor for detecting the air pollution level.

[0149] The processor (420) can determine the rotational speed of the blower fan (30) based on the first temperature of the air sucked in through the inlet (11) of the housing (10) in response to the start of humidification operation. The processor (420) can operate the humidification device (100) to perform humidification operation. Humidification operation can be performed according to user input or automatically according to indoor humidity. In other words, the processor (420) can operate the heating source (130) to perform humidification operation.

[0150] The memory (410) may store temperature and wind speed data regarding the rotational speed of the blower fan (30) corresponding to the first temperature of the inhaled air. The processor (420) may determine the rotational speed of the blower fan (30) corresponding to the first temperature of the inhaled air by referring to the temperature and wind speed data stored in the memory (410).

[0151] The processor (420) can set the target temperature of the mixed air based on user input obtained through the user interface (300) or a mobile device. The user can input a target temperature setting command to set the target temperature of the mixed air discharged from the humidifying air purifier (1) by operating the user interface (300) or a mobile device. The processor (420) can set the target temperature of the mixed air based on the target temperature setting command. By enabling the user to set the target temperature of the mixed air discharged from the humidifying air purifier (1), the user's convenience and satisfaction can be improved.

[0152] The processor (420) can adjust the rotational speed of the blower fan (30) based on the second temperature of the mixed air discharged through the second discharge port (101) of the housing (10) and the preset target temperature of the mixed air. For example, the processor (420) can determine the difference between the second temperature of the mixed air and the target temperature. The processor (402) can determine the average value of the second temperature of the mixed air detected during a preset detection time. The difference between the second temperature of the mixed air and the target temperature may represent the difference between the average value of the second temperature of the mixed air and the target temperature.

[0153] The processor (420) can increase or decrease the rotational speed of the blower fan (30) based on the difference between the second temperature of the mixed air and the target temperature being greater than or equal to a threshold value. The processor (420) can increase or decrease the rotational speed of the blower fan (30) more significantly as the difference between the second temperature of the mixed air and the target temperature increases.

[0154] The processor (420) can maintain the rotational speed of the blower fan (30) based on the difference between the second temperature of the mixed air and the target temperature being smaller than the threshold value.

[0155] Since the water vapor generated in the humidification device (100) and the air flowing through the blower fan (30) are mixed at the second discharge port (101), the faster the rotation speed of the blower fan (30), the faster the temperature of the mixed air can decrease. When the second temperature of the mixed air is higher than the target temperature and the difference between the second temperature of the mixed air and the target temperature is greater than or equal to a threshold value, the processor (420) can decrease the second temperature of the mixed air by increasing the rotation speed of the blower fan (30).

[0156] If the second temperature of the mixed air is lower than the target temperature and the difference between the second temperature of the mixed air and the target temperature is greater than or equal to a threshold value, the processor (420) can increase the second temperature of the mixed air by reducing the rotational speed of the blower fan (30).

[0157] Additionally, the processor (420) can adjust the power level of the heating source (130) based on the second temperature of the mixed air and the target temperature. For example, if the second temperature of the mixed air is higher than the target temperature, the processor (420) can lower the power level of the heating source (130) to lower the second temperature of the mixed air. If the second temperature of the mixed air is lower than the target temperature, the processor (420) can raise the power level of the heating source (130) to raise the second temperature of the mixed air to the target temperature.

[0158] In this way, the humidifying air purifier (1) can control at least one of the blower fan (30) and the heating source (130) to adjust the temperature of the mixed air discharged from the humidifying air purifier (1) to a target temperature set according to user input. By adjusting the temperature of the mixed air discharged from the humidifying air purifier (1) to a target temperature set by the user, the user's convenience and satisfaction can be improved.

[0159] FIG. 16 is a flowchart illustrating a control method for a humidifying air purifier according to one embodiment.

[0160] Referring to FIG. 16, the processor (420) of the humidifying air purifier (1) can set the target temperature of the mixed air discharged by the humidifying air purifier (1) based on user input obtained through the user interface (300) or a mobile device (1601). The user can input a target temperature setting command to set the target temperature of the mixed air discharged from the humidifying air purifier (1) by operating the user interface (300) or a mobile device. The processor (420) can set the target temperature of the mixed air based on the target temperature setting command.

[0161] The processor (420) can operate the humidification device (100) to perform humidification operation (1602). Humidification operation can be performed according to user input or automatically according to indoor humidity. In other words, the processor (420) can operate the heating source (130) to perform humidification operation. Additionally, the processor (420) can operate the blower fan (30) together.

[0162] As the heating source (130) operates, steam may be generated in the humidification device (100). The steam discharged from the humidification device (100) and the air flowing through the blower fan (30) may be mixed at the second discharge port (101) of the housing (10). The mixed air may be discharged to the outside of the humidifying air purifier (1) through the second discharge port (101) of the housing (10).

[0163] The processor (420) can control the first temperature sensor (210) to detect the first temperature of the air being sucked into the housing (10) through the inlet (11) of the housing (10) (1603). The processor (420) can determine the rotational speed of the blower fan (30) based on the detected first temperature of the air (1604). The processor (420) can determine the rotational speed of the blower fan (30) corresponding to the first temperature of the sucked air by referring to the temperature and wind speed data stored in the memory (410).

[0164] The processor (420) can control the second temperature sensor (220) to detect the second temperature of the mixed air discharged outside the housing (10) through the discharge port (12) of the housing (10) (1605). Since the mixed air discharged through the discharge port (12) contains hot steam, the second temperature of the mixed air may be relatively higher than the first temperature of the air sucked in through the inlet port (11).

[0165] The processor (420) can adjust the rotational speed of the blower fan (30) based on the second temperature of the mixed air and the target temperature of the mixed air (1606).

[0166] Figure 17 is a flowchart that explains in more detail the method of controlling the rotational speed of the blower fan described in Figure 16.

[0167] Referring to FIG. 17, the processor (420) of the humidifying air purifier (1) can determine the difference between the second temperature of the mixed air and the target temperature (1701). The processor (402) can determine the average value of the second temperature of the mixed air detected during a predetermined detection time. The difference between the second temperature of the mixed air and the target temperature may represent the difference between the average value of the second temperature of the mixed air and the target temperature.

[0168] The processor (420) can compare the difference between the second temperature of the mixed air and the target temperature with a threshold value (1702). The processor (420) can increase or decrease the rotational speed of the blower fan (30) based on whether the difference between the second temperature of the mixed air and the target temperature is greater than or equal to the threshold value (1703). The processor (420) can maintain the rotational speed of the blower fan (30) based on whether the difference between the second temperature of the mixed air and the target temperature is less than the threshold value (1704).

[0169] For example, since the water vapor generated in the humidifier (100) and the air flowing through the blower fan (30) are mixed at the second discharge port (101), the faster the rotation speed of the blower fan (30), the faster the temperature of the mixed air can decrease. If the second temperature of the mixed air is higher than the target temperature and the difference between the second temperature of the mixed air and the target temperature is greater than or equal to a threshold value, the processor (420) can decrease the second temperature of the mixed air by increasing the rotation speed of the blower fan (30). If the second temperature of the mixed air is lower than the target temperature and the difference between the second temperature of the mixed air and the target temperature is greater than or equal to a threshold value, the processor (420) can increase the second temperature of the mixed air by decreasing the rotation speed of the blower fan (30).

[0170] In this way, the humidifying air purifier (1) can control the blower fan (30) to adjust the temperature of the mixed air discharged from the humidifying air purifier (1) to a target temperature set according to user input. By adjusting the temperature of the mixed air discharged from the humidifying air purifier (1) to a target temperature set by the user, the user's convenience and satisfaction can be improved.

[0171] FIG. 18 is a flowchart illustrating a modified embodiment of the control method of a humidifying air purifier described in FIG. 16.

[0172] Referring to FIG. 18, steps 1801, 1802, 1803, 1804, and 1805 correspond to steps 1601, 1602, 1603, 1604, and 1605 described in FIG. 16. The processor (420) can adjust the power level of the heating source (130) as well as the rotational speed of the blower fan (30) based on the second temperature of the mixed air and the target temperature (1806).

[0173] For example, if the second temperature of the mixed air is higher than the target temperature, the processor (420) can lower the power level of the heating source (130) to lower the second temperature of the mixed air. If the second temperature of the mixed air is lower than the target temperature, the processor (420) can raise the power level of the heating source (130) to raise the second temperature of the mixed air to the target temperature.

[0174] In this way, the humidifying air purifier (1) can control at least one of the blower fan (30) and the heating source (130) to adjust the temperature of the mixed air discharged from the humidifying air purifier (1) to a target temperature set according to user input.

[0175] A humidifying air purifier according to one embodiment comprises: a housing including an inlet and an outlet; a blower fan that moves air sucked in through the inlet to the outlet; a humidifying device disposed within the housing that heats water and discharges water vapor through the outlet; a first temperature sensor that detects a first temperature of the air sucked in through the inlet; a second temperature sensor that detects a second temperature of the mixed air containing the water vapor discharged through the outlet; a memory that stores instructions; and one or more processors. When the instructions are executed by the one or more processors, the humidifying air purifier can determine the rotational speed of the blower fan based on the first temperature of the air sucked in through the inlet in response to the start of the humidification operation, and can adjust the rotational speed of the blower fan based on the second temperature of the mixed air discharged through the outlet and a preset target temperature of the mixed air.

[0176] When the instruction is executed by one or more of the above processors, the humidifying air purifier determines the difference between the second temperature of the mixed air and the target temperature, and can increase or decrease the rotational speed of the blower fan based on whether the difference is greater than or equal to a threshold value.

[0177] When the instruction is executed by one or more of the above processors, the humidifying air purifier can maintain the rotational speed of the blower fan based on the difference value being smaller than the threshold value.

[0178] When the instruction is executed by one or more processors, the humidifying air purifier determines the average value of the second temperature of the mixed air detected during a predetermined detection time, and can determine the difference value using the average value of the second temperature.

[0179] When the instruction is executed by one or more of the above processors, the humidifying air purifier can significantly increase or decrease the rotational speed of the blower fan as the difference value increases.

[0180] The above humidifying air purifier may include a heating source for heating the water. When the instruction is executed by one or more processors, the humidifying air purifier may adjust the power level of the heating source based on the second temperature of the mixed air and the target temperature.

[0181] The above humidifying air purifier may further include a user interface. When the instruction is executed by the one or more processors, the humidifying air purifier may set the target temperature of the mixed air based on user input obtained through the user interface.

[0182] The above humidifying air purifier may further include a communication circuit that communicates with a mobile device. When the instruction is executed by the one or more processors, the humidifying air purifier may set the target temperature of the mixed air based on user input obtained through the mobile device.

[0184] Adjusting the rotational speed of the blower fan may include determining the difference between the second temperature of the mixed air and the target temperature; and increasing or decreasing the rotational speed of the blower fan based on the difference being greater than or equal to a threshold value.

[0185] Adjusting the rotational speed of the blower fan may include maintaining the rotational speed of the blower fan based on the difference value being smaller than the threshold value.

[0186] Determining the difference value may include determining the average value of the second temperature of the mixed air detected during a predetermined detection time; and determining the difference value using the average value of the second temperature.

[0187] Adjusting the rotational speed of the blower fan may include increasing or decreasing the rotational speed of the blower fan more significantly as the difference value increases.

[0188] The above control method may further include adjusting the power level of a heating source included in the humidification device based on the second temperature of the mixed air and the target temperature.

[0189] The above control method may further include obtaining user input through a user interface or a mobile device; and setting the target temperature of the mixed air based on the user input.

[0190] The disclosed humidifying air purifier and its control method can adjust the temperature of the air discharged from the humidifying air purifier into an indoor space to a target temperature set by the user. Therefore, user convenience and satisfaction can be improved.
