Then, by operating the second fan 260, air suction and discharge (second flow) at the upper part of the air purifier 10 can be generated. The first flow and the second flow can be separated by the partition device 400.

Then, the third fan 330 can be selectively operated. When the third fan 330 is activated, the second flow can be generated even more strongly. That is, the second fan 260 and the third fan 330 generate a strong discharge airflow at the upper part of the air purifier 10, and the second fan 260 and the third fan 330 can discharge the air through the second discharge unit 305. Of course, the third fan 330 does not have to operate.

On the other hand, while the flow adjusting device 300 is in the second position, the first and second fans 160 and 260 can rotate to generate the first and second flows. Then, the third fan 330 can be operated. It is understood that the second position is a position inclined upward by a set angle with respect to the first position of the flow adjusting device 300. As an example, the set angle may be about 60 °.

More specifically, referring to FIG. 13, at least a part of the air discharged through the second discharge guide device 280 by the operation of the third fan 330 is inside the third fan housing 310. It can flow in and be discharged from the second discharge unit 305 via the third fan 330. By such an action, the purified air can reach a position far away from the air purifier 10.

Then, the flow adjusting device 300 can rotate in the left-right direction with respect to the axial direction in the state of being in the second position. FIG. 11 shows a state in which the flow adjusting device 300 is positioned so as to face in one direction (to the left with reference to FIG. 11) in the state of being in the second position. Here, the one direction may be a direction toward the left side 45 ° with the front of the air purifier 10 as the center.

The flow adjusting device 300 may be positioned so as to face in the other direction while being in the second position. Here, the other direction may be a direction toward the right side 45 ° with the front of the air purifier 10 as the center. That is, the rotation angle of the flow adjusting device 300 can be formed to be about 90 °.

In this way, since the flow adjusting device 300 can rotate in the left-right direction with respect to the axial direction, the effect that the discharge airflow can be sent to a long distance in various directions centering on the air purifier 10 is achieved.

FIG. 14 is a block diagram showing a controlled configuration of the air purifier according to the embodiment of the present invention, and FIG. 15 is a flowchart showing a control method of the air purifier according to the embodiment of the present invention.

Referring to FIG. 14, 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 237a. The dust sensor 237a can detect the amount of impurities or dust of a set size or less in the air sucked into the upper module 200. As an example, the dust sensor 237a can be configured to detect an amount of ultrafine dust of 2.5 μm or less. Therefore, the dust sensor 237a can be named "PM2.5 dust sensor".

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

Based on the information sensed by the dust sensor 237a and the gas sensor 237b, the air condition, that is, the air quality level can be determined. Specifically, the air quality level can be determined by combining the values output from the dust sensor 237a and the gas sensor 237b. As an example, the air quality level can be classified from level 1 to level 7, and it can be recognized that the higher the level, the worse the air condition.

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

The display device 600 can display level information regarding the degree of air pollution. As an example, the information on the degree of air pollution can be displayed in hue. Specifically, when the air pollution degree is recognized as "good condition", the display device 600 outputs "green".

On the other hand, when the air pollution degree is recognized as "normal state", the display device 600 outputs "yellow", and when the air pollution degree is recognized as "bad state", the display device 600 outputs "yellow". The display device 600 can output "orange". Then, when the air pollution degree is recognized as "a very bad state", the display device 600 outputs "red". As described above, by displaying the information on the air pollution degree in a separable hue, there is an advantage that the user can intuitively recognize the information on the air quality.

The air purifier 10 further includes an input unit 710 in 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 commands related to the operation mode of the air purifier 10 while the power of the air purifier 10 is turned on.

The operation mode of the air purifier 10 may include a manual operation mode, an automatic operation mode, and a lower module centralized operation mode. The user can select any one of the manual operation mode, the automatic operation mode, and the lower module centralized operation mode via the operation mode input unit 713. As an example, the operation mode input unit 713 may include a separate input unit capable of selecting each operation mode.

When the manual operation mode is selected via the operation mode input unit 713, the user can input the number of modules (devices) to be operated or the wind intensity (air volume). More specifically, 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, namely a first air purifying module 100, a second air purifying module 200, and a flow regulator 300. The three modules can be operated selectively or independently.

The clean mode input unit 715 is configured so that the number of modules to be operated can be determined among the three modules. Specifically, the cleaning mode input unit 715 may include a "single cleaning input unit", a "dual cleaning input unit", and a "circulating cleaning input unit". The single cleaning input unit is an input unit that can be input for operating the first air cleaning module 100 among the three modules, and the dual cleaning input unit is the first and second air cleaning modules 100, It is understood as an input unit that can be input to drive the 200. Then, the circulation cleaning input unit is understood as an input unit that can be input for operating the first and second air cleaning modules 100 and 200 and the flow adjusting device 300.

When the single cleaning input unit is input, the air purifier 10 is operated in the "single mode" in which the lower module 100 is independently operated, and when the dual cleaning input unit is input, the air purifier 10 is operated. 10 may be operated in a "dual mode" in which the upper and lower modules 100, 200 are combined and operated. Then, when the circulation cleaning input unit is input, the air purifier 10 can be operated in the "circulation mode" in which the combination operation of the upper and lower modules 100 and 200 and the flow adjusting device 300 is performed.

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 via the clean mode input unit 715, the user can determine the air volume discharged from the module via the air volume input unit 717. As an example, the air volume can be classified into "weak wind", "medium wind", and "strong wind". Of course, the rotation speed of the first fan 160, the second fan 260, or the third fan 330 can be determined according to the determined air volume.

On the other hand, when the automatic operation mode is selected via the operation mode input unit 713, the air purifier 10 is the number of modules to be operated based on the degree of air pollution recognized from the sensor device 237. And the wind intensity (air volume) can be determined.

As an example, when the air pollution level is "good" or "normal", it is determined that the first air purification module 100 of the modules is operated, and the air pollution level is "bad". In the case of "state", it can be determined that the first and second air cleaning modules 100 and 200 of the modules are operated.

The "normal" pollution level, i.e., the air quality level 4, is understood as the first reference pollution level in which only the first air purification module 100 can be operated. Then, the pollution level in the "bad state", that is, the air quality level 6, is understood as a second reference pollution level capable of operating the first and second air cleaning modules 100 and 200. That is, when the pollution degree level is equal to or higher than the first reference pollution degree and equal to or lower than the second reference pollution degree, the first and second air cleaning modules 100 and 200 can be operated.

At a pollution level equal to or higher than the second reference pollution level, the entire three modules can be operated. Specifically, when the air pollution level is "very bad", the entire three modules, namely the first and second air purification modules 100, 200 and the flow regulator 300, are operated. Can be decided. If the flow control device 300 is determined as the module to be operated, the flow control device 300 can be moved to a second position (see FIG. 13) and operated.

When the module to be operated is determined based on the information on the degree of air pollution, the air volume discharged from the module for which the operation is determined may be preset. As an example, the preset air volume may be "weak wind".

On the other hand, when the air volume input unit 717 is input in the process of operating the predetermined module with "weak wind" via the automatic operation mode, the air volume discharged from the module to be operated is preset. It can be adjusted by 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.

As an example, when the air pollution degree level is in a "good state", the air purification level can be maintained satisfactorily even if the first air purification module 100 is operated in a "weak wind", so that the first air The air volume of the cleaning module 100 is not changed. Then, a guide message can be output to the user via the display device 600. As an example, the guide message may include "the air condition is good and the clean condition can be maintained only by the current operation". Nevertheless, the display device 600 can guide the switch to the "manual operation mode" when the user demands a strong air volume.

On the other hand, when the air pollution level is in the "normal state", the air volume of the first air cleaning module 100 can be adjusted to "medium air". Then, it is possible to output a message to the user indicating that the air volume of the first air cleaning module 100 has been adjusted from "weak wind" to "medium wind".

On the other hand, when the air pollution level is in a "bad state", the air volumes of the first and second air cleaning modules 100 and 200 can be adjusted to "medium air", respectively. Then, it is possible to output a message to the user indicating that the air volume of the first and second air cleaning modules 100 and 200 has been adjusted from "weak wind" to "medium wind".

On the other hand, when the air pollution level is in a "very bad state", the air volumes of the first and second air cleaning modules 100 and 200 and the flow adjusting device 300 are adjusted to "strong wind", respectively. Can be done. Then, it is possible to output a message to the user indicating that the air volumes of the first and second air cleaning modules 100 and 200 and the flow adjusting device 300 have been adjusted from "weak wind" to "strong wind".

On the other hand, when the lower module centralized operation mode is selected via the operation mode input unit 713, the air volume of the first air cleaning module 100 is determined based on the degree of air pollution recognized from the sensor device 237. The operation of the first air cleaning module 100 can be performed by the determined air volume. When the lower module centralized operation mode is selected, the lower region of the clean space having a relatively high degree of pollution can be cleaned first while consuming relatively low power. In particular, the effect of the lower module intensive operation mode can be even more pronounced when an infant or baby with weak respiratory function is in the lower region of the clean space. The lower module centralized operation mode can be named a baby care mode.

As the degree of pollution sensed by the sensor device 237 increases, the air volume discharged from the first air cleaning module 100 can be determined to increase.

As an example, when the air pollution degree level is "good state" or "normal state", the air volume of the first air purification module 100 is determined as "weak wind", and the air pollution degree level is "". In the case of "bad condition", the air volume of the first air cleaning module 100 can be determined as "medium air". Then, when the air pollution level is in a "very bad state", the air volume of the first air cleaning module 100 can be determined as "strong wind".

According to such a method, the number (types) of modules to be operated even at the same air pollution level, depending on whether the user selects the automatic operation mode or the lower module centralized operation mode. ) Or the air volume can be controlled differently.

As an example, when the air pollution degree is in the range of the reference pollution degree, for example, in a "bad state", when the automatic operation mode is selected, the control unit 700 causes the first and second air cleaning modules 100. Can be controlled to discharge the first air volume respectively. On the other hand, when the air pollution degree is in the range of the reference pollution degree, for example, in a "bad state", when the lower module centralized operation mode is selected, the control unit 700 causes the first air cleaning module 100 to move. It can be controlled to discharge the second air volume. Here, the second air volume can be larger than the first air volume. According to such control, the effect that custom operation can be performed is achieved.

The air purifier 10 further includes a memory unit 720 that stores preset information for the operation of the air purifier 10. The information shown in Table 1 can be stored in the memory unit 720. That is, the value sensed by the sensor device 237, the mapping information regarding the air quality level, the mapping information regarding the pollution degree level, and the mapping information regarding the display hue can be stored. Then, the memory unit 720 may store information on the number of modules to be operated and the air volume when the automatic operation mode or the lower module centralized operation mode is selected.

In the air purifier 10, the first fan motor 165, based on the information sensed by the sensor device 237, the information input via the input unit 710, or the information stored in the memory unit 720, A second fan motor 265, a third fan motor 335, a first gear motor 363, a second gear motor 367, or a control unit 700 that controls the drive of the display device 600 is further included. The control unit 700 may determine whether or not the three modules are in operation according to the operation mode of the air purifier 10, and determine the air volume of the three modules based on the input or the information stored in advance. it can.

A control method for the air purifier 10 according to the embodiment of the present invention will be described with reference to FIG.

The air purifier 10 is turned on and the operation mode can be selected (S11). When the selected operation mode is the manual operation mode, the user inputs the module to be operated out of the three modules via the clean mode input unit 715, and the operation is performed via the air volume input unit 717. It is possible to determine the discharge air volume of the determined module. That is, the user can operate the air purifier 10 by selecting any one of the single mode, the dual mode, and the circulation mode of the air purifier (S13, S14).

When the selected operation mode is the automatic operation mode, the concentration of dust or gas contained in the air of the clean space is sensed via the sensor device 237, and the air quality level, that is, air is determined by the sensed result. The pollution level can be recognized (S15, S16).

Based on the recognized air pollution level, the control unit 700 can determine the module to be operated or the air volume. Specifically, as the level of air pollution increases, the number of devices in operation among the plurality of air cleaning modules 100, 200 and the flow control device 300 can be increased.

As an example, when the level regarding the degree of air pollution is relatively low, that is, when the degree of pollution level is "good state" or "normal state", the control unit 700 is used by the first air cleaning module 100. The air purifier 10 can be controlled to be operated.

On the other hand, when the level regarding the degree of air pollution is an intermediate level, that is, when the degree of pollution level is "bad", the control unit 700 operates the first and second air cleaning modules 100 and 200. The air purifier 10 can be controlled as such.

Then, when the level regarding the air pollution degree is high, that is, when the pollution degree level is "very bad state", the control unit 700 and the first and second air cleaning modules 100 and 200 The air purifier 10 can be controlled so that the flow control device 300 is operated.

At this time, the air volume of the module to be operated may be preset to "weak wind", but when the air volume input unit 717 is input, the air volume of the module to be operated can be changed (S17). ).

When the selected operation mode is the lower module centralized operation mode, the concentration of dust or gas contained in the air in the clean space is detected via the sensor device 237, and the air quality level is determined by the detected result. That is, the air pollution level can be recognized (S18, S19).

Based on the recognized air pollution level, the control unit 700 can determine the air volume of the first air cleaning module 100. Specifically, as the level of air pollution increases, the air volume of the first air purification module 100 can be increased (S20).

16 and 17 are views showing the state of air flow when only the lower module of the air purifier according to the embodiment of the present invention is driven.

Referring to FIG. 16, the air purifier 10 according to the embodiment of the present invention can be controlled so that only the lower module 100 is operated. As an example, among the operation modes of the air purifier 10, such an operation is possible in each of the manual operation mode, the automatic operation mode, and the lower module centralized operation mode.

When the lower module 100 is operated, the air in the clean space 50 can be sucked into the lower module 100 via the first suction portion 102. The sucked contaminated air can be purified while passing through the first filter member 120, and can be discharged to the clean space via the first fan 160 and the first discharge portion 105.

Since one of the three modules provided in the air purifier 10 is operated, the amount of air circulating through the air purifier 10, that is, the cleaning capacity is relatively small. Therefore, when the clean space 50 is relatively small, for example, when cleaning a small room, the user can select the manual operation mode and perform the single mode.

As an example, the cleaning capacity of the air purifier 10 can have _{Q 1} (m ^{3) per minute.} Of course, the cleaning capacity Q ₁ may differ slightly depending on the rotation speed of the first fan 160.

18 and 19 are views showing the state of air flow when the upper module and the lower module of the air purifier according to the embodiment of the present invention are driven.

The air purifier 10 according to the embodiment of the present invention can control the lower module 100 and the upper module 200 to be operated. As an example, among the operation modes of the air purifier 10, such an operation is possible in the manual operation mode and the automatic operation mode, respectively.

When the lower module 100 and the upper module 200 are operated, they can be sucked into the lower module 100 and the upper module 200 via the first and second suction portions 102 and 202, respectively. The contaminated air sucked into the lower module 100 can be purified while passing through the first filter member 120, and can be discharged to the clean space 50a via the first fan 160 and the first discharge portion 105.

Then, the contaminated air sucked into the upper module 200 can be purified while passing through the second filter member 220, and can be discharged to the clean space via the second discharge portion 305 via the second fan 260.

On the other hand, the third fan motor 335 can also be driven at a set rotation speed. If the upper module 200 is in operation but the third fan 330 is not driven, the third fan 330 may act as a resistor against the air that has passed through the second fan 260. is there. Therefore, the rotation speed of the third fan 330 can be adjusted to correspond to the rotation speed of the second fan 260.

Since two of the three modules provided in the air purifier 10 are operated, the amount of air circulating through the air purifier 10, that is, the cleaning capacity, is determined when only the lower module 100 is operated. Can be relatively large in comparison. Therefore, when the clean space 50a is relatively large, for example, when cleaning a large room, the user can select the manual operation mode and perform the dual mode.

As an example, the cleaning capacity of the air purifier 10 can have _{Q 2} (m ^{3) per minute.} Of course, the cleaning capacity Q ₂ may differ slightly depending on the rotation speed of the first fan 160. Then, the cleaning capacity Q ₂ can have a value larger than the cleaning capacity Q _1.

20 and 21 are views showing the state of air flow when the air purification module and the flow control device according to the embodiment of the present invention are driven.

The air purifier 10 according to the embodiment of the present invention can control the lower module 100, the upper module 200, and the flow adjusting device 300 to be operated. As an example, among the operation modes of the air purifier 10, such an operation is possible in the manual operation mode and the automatic operation mode, respectively.

When the lower module 100 and the upper module 200 and the flow adjusting device 300 are operated, they can be sucked into the lower module 100 and the upper module 200 via the first and second suction portions 102 and 202, respectively. The contaminated air sucked into the lower module 100 can be purified while passing through the first filter member 120, and can be discharged to the clean space 50b via the first fan 160 and the first discharge portion 105.

Then, the contaminated air sucked into the upper module 200 can be purified while passing through the second filter member 220, and can be discharged to the clean space via the second discharge portion 305 via the second fan 260. At this time, since the third fan 330 of the flow control device 300 can be driven together, the air that has passed through the second fan 260 can have a stronger wind force while passing through the third fan 330. As an example, the rotation speed of the third fan 330 may be equal to or higher than the rotation speed of the second fan 260.

The flow adjusting device 300 can have an upward rotating motion (see FIGS. 13 and 21) by the second guide mechanism, whereby air is discharged upward with reference to the air purifier 10. can do. Therefore, clean air can be discharged to a distance relatively far from the air purifier 10.

Then, since the flow adjusting device 300 rotates in the left-right direction (see A in FIG. 11) by the first guide mechanism, clean air is applied to the left side region and the right side region with reference to the air purifier 10. It can be discharged.

Since all three modules provided in the air purifier 10 are operated, the amount of air circulating through the air purifier 10, that is, the cleaning capacity, is determined when only the lower module 100 is operated, or the upper and lower parts. It can be relatively large compared to when modules 100, 200 are operated. Therefore, when the clean space 50b is relatively large, for example, when cleaning an office room or a large living room (room), the user can select the manual operation mode and perform the circulation mode.

As an example, the cleaning capacity of the air purifier 10 can have _{Q 3} (m ^{3) per minute.} Of course, the cleaning capacity Q ₃ may differ slightly depending on the rotation speed of the first fan 160. Then, the cleaning capacity Q ₃ can have a value larger than the cleaning capacity Q ₁ or the cleaning capacity Q _2.

According to the operation of such an air purifier, it is possible to operate the air purifier optimized according to the size of the clean space, the degree of air pollution, or the need for centralized operation in the lower area of the clean space. There are advantages.

According to this embodiment, a large number of modules including an air purifying module and a flow control device capable of discharging purified air that has passed through the air purifying module to a long distance are provided, and the size of the clean space or a desired amount of air clean can be adjusted. Accordingly, the large number of modules can be selectively driven, which improves air cleaning efficiency and increases user satisfaction, and thus has significant industrial availability.
