For example, the set angle may be about 60 degrees.

In detail, referring to FIG. 6, at least some of the air discharged through the second discharge guide device 280 is operated inside the third fan housing 310 by the operation of the third fan 330. Flows into the second discharge unit 305 through the third fan 330. By this action, the purified air can be reached to a position far from the air cleaner 10.

In addition, the flow regulating device 300 may be rotated in the left and right directions with respect to the axial direction while in the second position. 4 shows the state in which the flow regulator 300 is positioned to look in one direction (left direction of FIG. 4) while the flow regulator 300 is in the second position. Here, the one direction may be a direction toward the left 45 degrees around the front of the air purifier 10.

The flow regulating device 300 may be positioned to look in the other direction while in the second position. Here, the other direction may be a direction toward the right 45 degrees around the front of the air cleaner 10. That is, the rotation angle of the flow control device 300 may form about 90 degrees.

As such, since the flow regulating device 300 may be rotated in the left and right direction based on the axial direction, an effect of sending the discharge airflow to a long distance in various directions with respect to the air cleaner 10 appears.

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

The air cleaner 10 according to the embodiment of the present invention may be controlled to operate the lower module 100 and the upper module 200 and the flow regulator 300. For example, in the driving mode of the air cleaner 10, in the manual driving mode and the automatic driving mode, such driving may be possible.

When the lower module 100 and the upper module 200 and the flow control device 300 are operated, the lower module 100 and the upper module 200 are respectively provided through the first and second suction parts 102 and 202. May be inhaled. The contaminated air sucked into the lower module 100 may be purified while passing through the first filter member 120, and discharged into the clean space through the first discharge unit 105 through the first fan 160. .

The contaminated air sucked into the upper module 200 is purified while passing through the second filter member 220, and discharged into the clean space through the second discharge unit 305 through the second fan 260. Can be. At this time, since the third fan 330 of the flow regulator 300 may 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 a movement to rotate upward by the second guide mechanism, it may be disposed to be inclined toward the upper side of the second module (200). Accordingly, the air may be discharged upward based on the air cleaner 10. Therefore, the clean air can be discharged to a relatively long distance from the air cleaner 10.

In addition, since the flow adjusting device 300 performs a movement (see A of FIG. 4) to rotate in the left and right directions by the first guide mechanism, the flow regulating device 300 moves to the left region and the right region based on the air cleaner 10. Clean air can be discharged.

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

For example, the air purifier 10 may have a clean capability of Q3 (m3) per minute. Of course, the cleaning capacity (Q3) may vary slightly depending on the rotational speed of the fan (160,260,330). In addition, 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 cleaner, there is an advantage that the operation of the air cleaner is optimized according to the size of the clean space or the degree of air pollution.

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

Referring to FIG. 8, the air cleaner 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 may detect an amount of impurities or dust having a predetermined size or less in the air sucked into the upper module 200. For example, the dust sensor 237a may be configured to detect an amount of ultrafine dust of 2.5 μm or less. Therefore, the dust sensor 237a may be referred to as "PM2.5 dust sensor".

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

Air quality level One 2 3 4 5 6 7 Pollution Degree (Cleanliness) good usually Bad Very bad Display color green yellow Orange Red

Based on the information detected by the dust sensor 237a and the gas sensor 237b, an air condition, that is, an air quality level, may be determined. In detail, the air quality level may be determined by combining the values output from the dust sensor 237a and the gas sensor 237b. For example, the air quality level may be classified from level 1 to level 7, and the higher the level, the better the air condition may be recognized.

In the section where the air quality level is 1 to 2, the air pollution degree (cleanness) is "good condition", and in the section where the air quality level is 3-4, the air pollution degree (cleanness) is "normal state", In the section where the levels are 5 to 6, the air pollution degree (cleanness) is "bad state", and in the section where the air quality level is 7, it can be recognized that the air pollution degree (cleanness) is the "very bad state".

The display apparatus 600 may display level information regarding an air pollution level. For example, the information about the air pollution degree may be displayed in color. In detail, when it is recognized that the air pollution degree is "good state", the display apparatus 600 outputs "green".

On the other hand, if it is recognized that the air pollution degree is "normal", the display apparatus 600 outputs "yellow", and if it is recognized that the air pollution degree is "normal", the display apparatus 600 is " Orange "can be output. If the air pollution degree is recognized as being in a "very bad state", the display apparatus 600 outputs "red". In this way, the information on the air pollution degree is displayed in a distinguishable color, there is an advantage that the user can intuitively recognize the information on the air quality.

The air cleaner 10 further includes an input unit 710 for allowing a user to input a predetermined command. The input unit 710 includes a power input unit 711 for turning on or off the power of the air cleaner 10.

The input unit 710 further includes an operation mode input unit 713 for inputting a command regarding an operation mode of the air cleaner 10 when the power of the air cleaner 10 is turned on.

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

When the manual driving mode is selected through the driving mode input unit 713, the user may input the number of wind turbines or the number of modules (devices) to be operated. In detail, the input unit 710 further includes a clean mode input unit 715 for determining the number of modules to be operated. The module may include three modules, that is, the first air cleaning module 100, the second air cleaning module 200, and the flow regulator 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 clean input unit may be an input unit which may be input to drive the first air cleaning module 100 among the three modules, and the dual clean input unit may operate the first and second air cleaning modules 100 and 200. It is understood as an input unit that can be input in order to. In addition, the circulating clean input unit is understood as an input unit which can be input to operate the first and second air cleaning modules 100 and 200 and the flow control device 300.

When the single clean input unit is input, the air cleaner 10 is operated in the "single mode" in which the independent operation of the lower module 100 is performed. When the dual clean input unit is input, the air cleaner 10 is the upper and lower modules ( It may be operated in the "dual mode" in which the combined operation of 100 and 200 is performed. When the circulating clean input unit is input, the air cleaner 10 may be operated in a "circulation mode" in which a combination operation of the upper and lower modules 100 and 200 and the flow regulating 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 in which the flow control device 300 is inclined to the upper side of the upper module 200.

The input unit 710 further includes a wind amount input unit 717 for determining the strength of the air discharged from the module to be operated, that is, the amount of air. After determining the module to be operated through the clean mode input unit 715, the user may determine the air volume discharged from the module through the air volume input unit 717. In one example, the air volume may be divided into "soft wind", "mid wind" and "strong wind". Of course, the rotation speed of the first fan 160, the second fan 260, or the third fan 330 may be determined according to the determined air volume.

On the other hand, when the automatic operation mode is selected through the operation mode input unit 713, the air purifier 10 is based on the air pollution degree recognized from the sensor device 237, the number and wind strength of the module to be operated (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 of the module is operated, when the air pollution level is "bad", It may be determined that the first and second air cleaning modules 100 and 200 of the modules are operated.

The pollution level of the "normal state", that is, the air quality level 4, is understood as a first reference pollution degree capable of operating only the first air cleaning module 100. The pollution level of the "bad state", that is, the air quality level 6, is understood as a second reference pollution degree capable of operating the first and second air cleaning modules 100 and 200. That is, when the pollution level is greater than or equal to the first reference pollution degree and less than or equal to the second reference pollution degree, the first and second air cleaning modules 100 and 200 may be operated.

At a pollution level above the second reference pollution level, all three modules may be operated. In detail, when the air pollution level is "very bad", it may be determined that all three modules, that is, the first and second air cleaning modules 100 and 200 and the flow regulator 300 are operated. When it is determined that the flow regulator 300 is a driven module, the flow regulator 300 may be operated by moving to the second position (see FIG. 13).

When the module to be operated is determined based on the air pollution degree information, the air volume discharged from the determined module may be set in advance. In one example, the preset air volume may be "soft air".

On the other hand, in the process of operating a predetermined module "light wind" through the automatic driving mode, when the air volume input unit 717 is input, the air volume discharged from the operating module can be adjusted according to the preset information. The user inputs the air volume input unit 717 because it can be recognized that the user wants a stronger air volume.

For example, when the air pollution level is “good”, the first air cleaning module 100 may maintain a good air cleaning level even when the first air cleaning module 100 is operated in “weak air”. Does not change the air volume. The display apparatus 600 may output a guide message to the user. For example, the guide message may include "the air condition is good and can be kept clean only by the current operation". Nevertheless, when the user requests a strong air volume, the display apparatus 600 may guide the switch to the "manual driving mode".

On the other hand, when the air pollution level is "normal", the air volume of the first air cleaning module 100 may be adjusted to "mid-air". In addition, the user may output a message indicating that the air volume of the first air cleaning module 100 is adjusted from "soft air" to "mid wind."

On the other hand, when the air pollution level is a "bad state", the air volume of the first and second air cleaning module (100,200) may be adjusted to "mid wind" respectively. In addition, the user may output a message indicating that the air volume of the first and second air cleaning modules 100 and 200 is adjusted from "soft air" to "mid wind."

On the other hand, when the air pollution level is a "very bad state", the air volume of the first and second air cleaning module (100, 200) and the flow control device 300 may be adjusted to "strong wind", respectively. In addition, the user may output a message indicating that the air volumes of the first and second air cleaning modules 100 and 200 and the flow control device 300 have been adjusted from “soft wind” to “strong wind”.

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

The air cleaner 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 control unit 700 which controls the driving of the second fan motor 265, the third fan motor 335, the first gear motor 363, the second gear motor 367, or the display apparatus 600 is further included.

Thereafter, the sensing means 123 detects the detachment of the filter member 120, and the controller 124 supplies power of the auxiliary battery 122 included in the filter member 120 to the dust collecting filter 121. (S120)

Therefore, the dust and the like collected in the dust collecting filter 121 is not separated from the dust collecting filter 121, it is possible to maintain the collected state.

Thereafter, the remaining amount of the auxiliary battery 122 is checked (S130).

If the remaining amount of the auxiliary battery 122 is less than the reference value, the display means 125 outputs a notification warning of the discharge (S140).

For example, red lighting may proceed.

After the discharge warning notification as described above, the elapsed time is checked with a timer (S150).

Thereafter, when a preset input time elapses, power supply from the auxiliary battery 122 to the dust collecting filter 121 is cut off (S160).

Thereafter, the display means 125 outputs a notification informing the discharge state. (S170)

For example, green lighting may be performed.

Afterwards, the cleaning and inspection of the filter member 120 including the dust collecting filter 121 is finished, and when the filter member 120 is mounted inside the air purification module 100, the auxiliary battery included in the filter member 120 ( The charging of 122) is performed (S180).

According to the present invention as described above, when the filter member 120 is separated from the air cleaner body, the instant power supply from the auxiliary battery 122 to the dust collecting filter 121 can be made.

Therefore, even when the filter member 120 is separated from the air purifier main body for cleaning the dust collecting filter 121, power is applied to the dust collecting filter 121, so that the fine dust collected in the dust collecting filter 121 does not escape. State can be maintained.

That is, when the dust collecting filter 121 is detached and moved, generation of dust may be minimized.

In addition, it is possible to prevent the situation in which the dust separated from the dust collecting filter 121 is introduced into the air purification module 100, it is possible to increase the stability of the product.

In addition, the discharging of the auxiliary battery 122 may be noticed, and the discharging state may be displayed to the outside, thereby increasing user convenience.
