And, the third fan 330 can be selectively operated. When the third fan 330 operates, the second flow may be more strongly generated. That is, a strong discharge air flow is generated at the upper part of the air purifier 10 by the second fan 260 and the third fan 330 and can be discharged through the second discharge unit 305 . Of course, the third fan 330 may not operate.

Meanwhile, in a state in which the flow controller 300 is in the second position, the first and second fans 160 and 260 rotate to generate the first and second flows. Also, the third fan 330 may operate. The second position is understood to be a position inclined upward by a set angle with respect to the first position of the flow control device 300 . For example, the setting angle may be about 60 degrees.

In detail, referring to FIG. 6 , by the operation of the third fan 330, at least some of the air discharged through the second discharge guide device 280 moves inside the third fan housing 310. and may be discharged from the second discharge unit 305 via the third fan 330. By this action, the purified air can reach a location far away from the air purifier 10 .

And, the flow control device 300, in the state in the second position, can be rotated in the left and right directions relative to the axial direction. 4 shows a state in which the flow control device 300 is positioned so as to look in one direction (a left direction based on FIG. 4) in a state in the second position. Here, the one direction may be a direction toward the left 45 degrees with the front of the air purifier 10 as the center.

The flow control device 300 may be positioned to look in another direction in the second position. Here, the other direction may be a direction toward the right 45 degrees with the front of the air purifier 10 as the center. That is, the rotation angle of the flow control device 300 may form about 90 degrees.

In this way, since the flow control device 300 can be rotated in the left and right directions based on the axial direction, there is an effect that the discharge air flow can be sent to a long distance in various directions with the air purifier 10 as the center.

7 is a perspective view showing air flow when an air cleaning module and a flow controller according to an embodiment of the present invention operate.

In the air purifier 10 according to an embodiment of the present invention, the lower module 100, the upper module 200, and the flow regulator 300 may be controlled to operate. For example, among the operation modes of the air purifier 10, each of these operations may be possible in a manual operation mode and an automatic operation mode.

When the lower module 100, the upper module 200, and the flow control device 300 are operated, the lower module 100 and the upper module 200 pass through the first and second suction parts 102 and 202, respectively. can be inhaled. Contaminated air sucked into the lower module 100 is purified while passing through the first filter member 120, and can be discharged to a clean space through the first discharge part 105 through the first fan 160. .

Then, the polluted air sucked into the upper module 200 is purified while passing through the second filter member 220, and is discharged to the clean space through the second discharge part 305 through the second fan 260. can At this time, since the third fan 330 of the flow controller 300 can be driven together, the air passing through the second fan 260 passes through the third fan 330 and has a stronger blowing force. can have

The flow control device 300 may have an upward rotational movement by the second guide mechanism and may be inclined upwardly of the second module 200 . Accordingly, air may be discharged toward the upper side with respect to the air purifier 10 . Therefore, clean air can be discharged from the air purifier 10 to a relatively long distance.

In addition, since the flow control device 300 rotates in the left and right directions by the first guide mechanism (refer to A in FIG. 4 ), the flow control device 300 moves to the left and right areas with respect to the air purifier 10 . Clean air can be discharged.

Since all three modules provided in the air purifier 10 are operated, the amount of air circulated through the air purifier 10, that is, the cleaning capacity, is reduced when only the lower module 100 is operated, or when the upper and lower modules 100 and 200 are operated. Compared to the case of driving, it may be relatively large. Therefore, when the clean space is relatively large, for example, when cleaning an office or a large living room (room), the user may select the manual operation mode and perform the circulation mode.

For example, the cleaning capacity of the air purifier 10 may have Q3 (m3) per minute. Of course, the cleaning capacity (Q3) may vary somewhat depending on the rotational speed of the first fan (160, 260, 330). Also, the cleaning capacity Q3 may have a larger value than the cleaning capacity Q1 or the cleaning capacity Q2.

According to the operation of the air purifier, there is an advantage in that it is possible to operate the air purifier optimized according to the size of the clean space or the degree of air pollution.

8 is a block diagram showing a controllable configuration of an air purifier according to an embodiment of the present invention.

Referring to FIG. 8 , the air purifier 10 according to the embodiment of the present invention includes a sensor device 237. The sensor device 237 may include a dust sensor. The dust sensor may detect the amount of impurities or dust smaller than a set size in the air sucked into the upper module 200 . For example, the dust sensor may be configured to detect the amount of ultra-fine dust of 2.5 μm or less. Accordingly, the dust sensor may be referred to as a "PM2.5 dust sensor".

The sensor device 237 may further include a gas sensor. The gas sensor can detect the amount of harmful gas, for example, a combustible gas, a reducing gas, and an organic solvent gas included in the air sucked into the upper module 200 .

air quality level One 2 3 4 5 6 7 Pollution degree (cleanliness) good usually bad very bad display color green yellow Orange Red

An air condition, that is, an air quality level may be determined based on information sensed by the dust sensor and the gas sensor. In detail, the air quality level may be determined by combining values output from the dust sensor and the gas sensor. For example, the air quality level may be classified from level 1 to level 7, and the higher the level, the poorer the air quality may be recognized.

And, in the section where the air quality level is 1 to 2, the air pollution level (cleanliness) is "good condition", and in the section where the air quality level is 3 to 4, the air pollution level (cleanliness level) is "normal condition", and the air quality In the section where the level is 5 to 6, the air pollution level (cleanliness) is "poor", and in the section where the air quality level is 7, the air pollution (cleanliness) can be recognized as "very bad".

Level information about air pollution may be displayed on the display device 600 . For example, the air pollution information may be displayed in color. In detail, when the air pollution level is recognized as "good", the display device 600 outputs "green".

On the other hand, when the air pollution level is recognized as "normal", the display device 600 outputs "yellow", and when the air pollution is recognized as "normal", the display device 600 outputs "yellow". Orange" can be printed. And, when it is recognized that the air pollution level is "very bad", the display device 600 outputs "red". As such, since the air pollution information is displayed in distinguishable colors, the user can intuitively recognize the air quality information.

The air purifier 10 further includes an input unit 710 through which a user can input a predetermined command. The input unit 710 includes a power input unit 711 capable of turning on or off the power of the air purifier 10 .

The input unit 710 further includes an operation mode input unit 713 capable of inputting a command related to the operation mode of the air purifier 10 when the power of the air purifier 10 is turned on.

The operation mode of the air purifier 10 may include a manual operation mode and an automatic operation mode. The user may select one of the manual driving mode and the automatic driving mode through the driving mode input unit 713 . For example, the driving mode input unit 713 may include a separate input unit capable of selecting each driving mode.

When the manual operation mode is selected through the operation mode input unit 713, the user may input the number of modules (devices) to be operated or wind speed (air volume). In detail, the input unit 710 further includes a clean mode input unit 715 that determines the number of modules to be operated. The module may include three modules, that is, a first air cleaning module 100, a second air cleaning module 200, and a flow controller 300. The three modules can be operated selectively or independently.

The clean mode input unit 715 is configured to determine the number of modules to be operated among the three modules. In detail, the clean mode input unit 715 may include a "single clean input unit", a "dual clean input unit", and a "cyclic clean input unit". The single cleaning input unit is an input unit that can be input to operate the first air cleaning module 100 among the three modules, and the dual cleaning input unit is used to operate the first and second air cleaning modules 100 and 200. It is understood as an input unit that can be entered for. And, the circulation cleaning input unit is understood as an input unit that can be input to operate the first and second air cleaning modules 100 and 200 and the flow control device 300 .

When the single cleaning input unit is input, the air purifier 10 is operated in a "single mode" in which the lower module 100 is independently operated, and when the dual cleaning input unit is input, the air purifier 10 operates in the upper and lower modules ( 100 and 200) can be operated in “dual mode” in which combined operation is performed. In addition, when the circulation cleaning input unit is input, the air purifier 10 may be operated in a “circulation mode” in which a combined operation of the upper and lower modules 100 and 200 and the flow control device 300 is performed. Here, the operation of the flow control device 300 in the "circulation mode" means a case in which the flow control device 300 is operated in a state where the flow control device 300 protrudes obliquely upward from the upper module 200 .

The input unit 710 further includes an air volume input unit 717 capable of determining the intensity of air discharged from the module to be operated, that is, the air volume. After determining the module to be operated through the clean mode input unit 715, the user can determine the air volume discharged from the corresponding module through the air volume input unit 717. For example, wind volume may be divided into "weak wind", "medium wind" and "strong wind". Of course, the number of revolutions of the first fan 160 , the second fan 260 , or the third fan 330 may be determined according to the determined air volume.

Meanwhile, when the automatic operation mode is selected through the operation mode input unit 713, the air purifier 10 determines the number of modules to be operated and wind speed based on the air pollution level recognized by the sensor device 237. (air volume) can be determined.

For example, when the air pollution level is “good” or “normal”, it is determined that the first air cleaning module 100 among the modules is in operation, and the air pollution level is “bad”, It may be determined that the first and second air cleaning modules 100 and 200 among the modules are operated.

The pollution level of the “normal state”, that is, the air quality level 4 is understood as a first standard pollution level at which only the first air cleaning module 100 can be operated. In addition, the pollution level of the “bad state”, that is, the air quality level 6 is understood as a second standard pollution level at which the first and second air cleaning modules 100 and 200 can be operated. That is, when the pollution level is higher than the first standard pollution level and lower than the second standard pollution level, the first and second air cleaning modules 100 and 200 may be operated.

At a pollution level equal to or higher than the second reference pollution level, all of the three modules may be operated. In detail, when the air pollution level is “very bad”, it may be determined that all of the three modules, that is, the first and second air cleaning modules 100 and 200 and the flow controller 300 are operated. When the flow control device 300 is determined as a module to be operated, the flow control device 300 may move to the second position (see FIG. 13) and be operated.

When a module to be operated is determined based on the air pollution level information, the amount of air discharged from the module for which operation is determined may be set in advance. For example, the preset wind volume may be “weak wind”.

On the other hand, in the process of operating a certain module with "weak wind" through the automatic operation mode, when the air volume input unit 717 is input, the air volume discharged from the operated module can be adjusted according to preset information. The reason why the user inputs the air volume input unit 717 is that it can be recognized that the user desires a stronger air volume.

For example, when the air pollution level is "good", the first air cleaning module 100 can maintain a good air cleaning level even when the first air cleaning module 100 is operated with "weak wind", so the first air cleaning module 100 ) does not change the air volume. And, through the display device 600, a guide message can be output to the user. For example, the guide message may include "The air condition is good, and it is possible to maintain a clean state only with the current operation". Nonetheless, when the user requests a strong air volume, the display device 600 may guide the conversion to the “manual driving mode”.

Meanwhile, when the air pollution level is "normal", the air volume of the first air cleaning module 100 may be adjusted to "neutral". In addition, a message indicating that the air volume of the first air cleaning module 100 has been adjusted from "light wind" to "medium wind" may be output to the user.

On the other hand, when the air pollution level is "poor", the air volume of the first and second air cleaning modules 100 and 200 may be adjusted to "low air", respectively. In addition, a message indicating that the air volume of the first and second air cleaning modules 100 and 200 has been adjusted from “light air” to “medium air” may be output to the user.

Meanwhile, when the air pollution level is in a "very bad state", the air volume of the first and second air cleaning modules 100 and 200 and the flow controller 300 may be adjusted to "strong wind", respectively. In addition, a message indicating that the air volume of the first and second air cleaning modules 100 and 200 and the flow controller 300 has been adjusted from "weak wind" to "strong wind" can be output to the user.

The air purifier 10 further includes a memory unit 720 for storing preset information for operation of the air purifier 10 . Information described in [Table 1] may be stored in the memory unit 720. That is, the value sensed by the sensor device 237, mapping information on air quality level, mapping information on pollution level, and mapping information on display color may be stored. In addition, the memory unit 720 may store information about the number of modules to be operated and air volume when the automatic operation mode is selected.

The air purifier 10 includes a first fan motor 165 based on information detected by the sensor device 237, information input through the input unit 710, or information stored in the memory unit 720. , The second fan motor 265, the third fan motor 335, the first gear motor 363, the second gear motor 367, or the control unit 700 for controlling driving of the display device 600 is further included The control unit 700 may determine whether or not to operate the three modules according to the operation mode of the air purifier 10 and determine air volume of the three modules according to input or pre-stored information.

<Control method>

11 is a flow chart showing a control method of an air purifier according to an embodiment of the present invention.

Hereinafter, a control method of the air purifier 10 according to an embodiment of the present invention will be described with reference to FIG. 11 .
