Meanwhile, in the present embodiment, the input unit 500 is configured in the form of a button, but is not limited thereto, and may include all various input methods in which an operation command can be input by a user touching or pressing it. In addition, it is possible to command by voice, and it will be possible to input an operation command wirelessly through a remote control or a smart phone.

The control unit 600 controls the air volume of the first blowing fan 160, the second blowing fan 260, and the circulation fan 330 according to an operation command input from the input unit 500, and the circulator It is possible to control the movement of 300 and the left and right rotation.

The control unit 600 may receive an operation command from the input unit 500, receive indoor air status information from the sensor unit 700, and the first blowing fan motor 145, the second blowing A control command may be transmitted to the fan motor 245, the circulation fan motor 335, the position conversion unit 340 and the rotation unit 350 (see FIG. 3 ).

The control unit 600 sets (inputs) the indoor air level according to the indoor air condition (fine dust concentration, ultrafine dust concentration, gas amount, etc.). For example, the controller 600 may assign a rating to four levels of'good','normal','bad', and'very bad' according to the indoor air measured by the sensor unit 700.

In the control unit 600, a rotation speed (rpm) of the first blowing fan 160, the second blowing fan 260, and the circulation fan 330 is preset step by step, and the Whether the circulator 300 moves and rotates in the left and right directions is set. In other words, the control unit 600 may apply an air volume step to each of the first blowing fan 160, the second blowing fan 260, and the circulation fan 330. For example, according to the order in which the air volume increases, air volume steps such as'weak','medium','strong','turbo', and'maximum air volume' may be assigned, and the first blowing fan ( 160), a rotation speed (rpm) of the second blowing fan 260 and the circulation fan 330 may be set.

When the auto mode is input from the input unit 500, the control unit 600 performs the first air cleaning module 100 and the second air cleaning according to the state of indoor air measured through the sensor unit 700. The module 200 and the circulator 300 are operated.

That is, when the auto mode is activated, the sensor unit 700 measures (detects) the state of indoor air (fine dust concentration, ultrafine dust concentration, and amount of gas), and the controller 600 performs the sensor unit ( 700) can be given a rating to the indoor air.

In addition, the control unit 600 may operate the first blowing fan 160, the second blowing fan 260, and the circulation fan 330 in the air volume step set in advance corresponding to the indoor air level. For example, when the indoor air rating is'good', the first blowing fan 160, the second blowing fan 260, and the circulation fan 330 may be operated in a'weak' step, and the indoor air When the air rating is'normal', the first blowing fan 160 is in the'medium' stage, when the indoor air rating is'bad', the'strong' stage, and when the indoor air rating is'very bad', the first blowing fan 160, The second blowing fan 260 and the circulation fan 330 may be operated.

In addition, the controller 600 may control the movement of the circulator 300 and rotation in the left and right directions corresponding to the indoor air level. For example, when the indoor air rating is'Good' or'Normal', the controller 600 does not rotate left and right while the circulator 300 is lying down (first position) (fixed), When the indoor air rating is'bad', the circulator 300 is inclined (second position) and does not rotate left and right, and when the indoor air rating is'very bad', the circulator 300 is It can be operated to rotate left and right while standing inclined (second position).

On the other hand, when a driving mode other than the auto mode is operated, the control unit 600 may be configured with the first blowing fan 160 and the second blowing fan 260 at a preset rotational speed (rpm) according to each driving mode. And rotating the circulation fan 330, and controlling the movement of the circulator 300 and rotation in the left and right directions. In this case, the user can directly control the air volume level of the first blowing fan 160, the second blowing fan 260, or the circulation fan 330 through the input unit 500, and the circulator 300 ) Movement and left and right rotation can be directly controlled.

In addition, in the pet mode operated to intensively care for contaminants generated by the companion animal, the control unit 600 controls the pre-filter 125 to increase the amount of air passing through the pre-filter 125. It is possible to control the rotation speed of the corresponding blower fan.

For example, in the present invention, when a pet mode is input through the input unit 500, the air volume of the first blowing fan 160 may be increased. That is, the first blowing fan 160 may be rotated by raising the air volume step of the first blowing fan 160 before the pet mode is input through the input unit 500 by one step. For example, when the air volume level of the first blowing fan 160 is'weak' and a pet mode is input, the air volume level of the first blowing fan 160 is increased to'medium' to allow the first blowing The fan 160 can be rotated.

In addition, in the present invention, when a pet mode is input through the input unit 500, the air volume of the second blowing fan 260 and the circulation fan 330 is also the second blowing fan 260 in a preset pet mode. ) And the air volume of the circulation fan 330. That is, the air volume step of the second blowing fan 260 and the circulation fan 330 may be increased by one step. For example, when the air volume level of the second blowing fan 260 and the circulation fan 330 is'weak', in the pet mode, the second blowing fan 260 and the second blowing fan 260 and the The circulation fan 330 can be rotated.

On the other hand, in the pet mode, the rotational speed (RPM) of the first blowing fan 160 and the rotational speed (RPM) of the second blowing fan 260 following the rise of the above-described air volume step are different from each other. Can be set.

In more detail, in the pet mode, a rotational speed increase value of the first blowing fan 160 may be greater than a rotational speed increase value of the second blowing fan 260.

As described above, since the pollutants generated by companion animals are relatively heavy and large in size, they may be mainly distributed around the first air cleaning module 100 at a relatively low height. Therefore, in the pet mode, the first blowing fan 160 increases the rotational speed higher than the second blowing fan 260 to increase the suction power, so that contaminants generated by the companion animal can be quickly sucked in. .

In addition, in the pet mode, a rotation speed of the first blowing fan 160 may be greater than a rotation speed of the second blowing fan 260.

For example, in the pet mode, when the air volume level of the first blowing fan 160 is weak, the rotational speed of the first blowing fan 160 may be set to 800 (RPM), and the first blowing fan ( When the air volume step of 160) is in progress, the rotational speed of the first blowing fan 160 may be set to 1150 (RPM). And when the air volume level of the second blowing fan 260 is weak, the rotational speed of the second blowing fan 260 may be set to 630 (RPM), and the air volume level of the second blowing fan 260 is in progress. In this case, the rotational speed of the second blowing fan 260 may be set to 810 (RPM).

That is, in the pet mode, the first blowing fan 160 may have a greater rotational speed than the second blowing fan 260. In addition, the width of the rotational speed increase according to the increase of the air volume may be greater than that of the first blowing fan 160 and the second blowing fan 260.

Meanwhile, in the present embodiment, when a pet mode is input through the input unit 500, the controller 600 may operate the pet mode after operating the auto mode. In this case, the first blowing fan 160 may be rotated by raising the rotation speed (rpm) of the first blowing fan 160 operated in the auto mode by one step. For example, when the pet mode is input during operation in the'weak' stage in the auto mode, the rotation speed (rpm) of the first blowing fan 160 is increased to the'medium' stage, and the first blowing fan 160 is Can be rotated.

Therefore, when the pet mode is operated according to the present invention, the rotational speed (rpm) of the first blowing fan 160 and/or the second blowing fan 260 increases, thereby increasing the amount of air that sucks air, and The amount of cleansing can be increased. In addition, as the rotational speed (rpm) of the circulation fan 330 increases, purified air can be sent to a farther distance more quickly, so that fresh air can be rapidly circulated.

In addition, when the pet mode is input, the control unit 600 turns on the pet mode display 142 of the display device 400 and turns off the indication that the driving mode excluding the pet mode is in operation. Can be controlled.

On the other hand, the control unit 600 controls to cancel the pet mode input when a bedtime reservation is input before the pet mode is input, and when the bedtime reservation is input while the pet mode is operating, the existing operation while terminating the pet mode. You can return to the running mode (old mode).

Accordingly, according to the present invention, the operation of the pet mode may be restricted when sleeping, and when a sleep reservation is input during the operation of the pet mode, the pet mode may be terminated to prevent noise generation.

The sensor unit 700 is configured to detect a fine dust concentration, an ultra fine dust concentration, and whether or not an odor occurs, and is signally connected to the control unit 600.

The sensor unit 700 may be installed in the first air cleaning module 100 or the second air cleaning module 200. The sensor unit 700 may include a dust sensor that detects the amount of dust in the air and a gas sensor that detects the amount of gas in the air.

Meanwhile, FIG. 6 shows a flow chart for a control method of an air purifier equipped with a pet mode according to an embodiment of the present invention, and FIG. 7 shows an operation step of an auto mode in the control method of an air purifier equipped with a pet mode. A flowchart is disclosed.

1 to 3, 6, and 7, the method of controlling an air purifier equipped with a pet mode according to an embodiment of the present invention includes a pet mode entry step (S10), an auto mode operation step (S20), and a pet. It includes a mode operation step (S30).

In the pet mode entry step (S10), when the pet mode is input (S11), it is determined to enter the pet mode (S12) according to whether or not a bedtime reservation is set (S12).

At this time, if the sleep reservation is set in advance, the input of the pet mode is canceled, and if the sleep reservation is not set (not set), the automatic mode operation step (S20) is performed.

That is, when the user presses the pet mode button 510 in the input unit 500 to input the pet mode, the control unit 600 determines whether or not a sleep reservation has already been set (input). As a result, if the user inputs the sleep reservation button 520 before pressing the pet mode button 510 to set the sleep reservation, the control unit 600 cancels the pet mode input command, and the pet mode button If the sleep reservation button 520 is not input before pressing 510, the control unit 600 operates the auto mode.

In the auto mode operation step (S20), if a bedtime reservation is not set in the pet mode entry step (S10), the indoor air condition is sensed (S21), and a preset indoor air rating is assigned (S22), and The first blowing fan 140 of the air purifier is rotated (S23) with an air volume set in advance according to the air grade.

That is, when the auto mode operation step (S20) is started, the sensor unit 700 detects indoor air conditions such as fine dust concentration, ultra fine dust concentration, and odor occurrence (S21), and the sensed air condition Information is transmitted to the control unit 600, and the control unit 600 assigns an indoor air rating according to a preset standard using the air condition information received from the sensor unit 700 (S22). For example, if the concentration of fine dust is 0 ㎍/㎥ or more and 30 ㎍/㎥ or less, it is'Good', if it is 31 ㎍/㎥ or more and 80 ㎍/㎥ or less, it is'Normal', and 81 ㎍/㎥ or more and 150 ㎍/㎥ or less. In case of'bad' in case of 151 ㎍/㎥ or more, it can be given a grade as'very bad'. In case of ultrafine dust concentration of 0 ㎍/㎥ or more and 15 ㎍/㎥ or less, it is'good' and 16 ㎍/㎥ If it is more than 35 ㎍/㎥, it can be given a grade as'Normal', if it is more than 36 ㎍/㎥ and less than 75 ㎍/㎥, it is'bad', and if it is more than 76 ㎍/㎥, it can be given a grade as'very bad'.

The control unit 600 may control the rotation speed of the first blowing fan 140 in response to the indoor air level assigned as described above. For example, the controller 600 may control the amount of air of the first air cleaning module 100 by controlling the rotational speed (rpm) of the first blowing fan 140 (S23). In this case, the control unit 600 may preset the air volume level of the first blowing fan 160. For example, stages can be assigned in the order of increasing air volume, such as'weak','medium','strong','turbo', and'maximum air volume'. In addition, the rotational speed (rpm) of the first blowing fan 160 for each step may be set in advance.

For example, when the indoor air rating is'good', the controller 600 may control the first blowing fan 140 with'about', which is an air volume level matched with the'good'. In this case, the rotational speed of the first blowing fan 140 may be a speed previously stored to match the “about”. Examples of air volume steps for indoor air ratings are shown in Table 1 to be described later.

In addition, in the auto mode operation step S20 in the present embodiment, the controller 600 may control the movement of the circulator 300 and rotation in the left and right directions according to the indoor air level. For example, when the indoor air rating is'bad', the circulator 300 may rotate to draw an arc upward from a state in which the air is laid upward (refer to FIG. 2). Accordingly, the circulator 300 may be erected to be inclined with the central axis of the air cleaning module 100 and 200. In the'bad', while the circulator 300 is erect, it may not rotate left and right. In addition, when the indoor air rating is “very bad”, the circulator 300 may be rotated in a circumferential direction with respect to the central axis of the air cleaning module 100 or 200 while being inclined. That is, in the'very bad', the circulator 300 may be controlled to rotate in the left and right directions in an inclined erect state.

In addition, in the auto mode operation step S20, the controller 600 may inform the user that the auto mode is operating through the display device 400.

In the pet mode operation step (S30), the display device 400 of the air purifier cancels (off) the indication that the auto mode is in operation, and displays (on) the content that the pet mode is in operation (S31), and the The air volume of the first blowing fan 140 is increased than the air volume of the first blowing fan 140 operated in the auto mode operation step (S20) (S32), and a sleep reservation is entered or operated while the pet mode is operating. When a command for changing the mode is input, the pet mode is terminated (S33).

That is, in the pet mode operation step (S30), the control unit 600 activates (on) the pet mode display 420, and the indication that other driving modes other than the pet mode display 420 are operating ends. do.

Thereafter, the control unit 600 increases the air volume of the first blowing fan 140 than the air volume of the first blowing fan 140 operated in the auto mode operation step (S20) (S32). For example, when the pet mode is activated, when the indoor air rating is'good', the air volume level of the first blowing fan 140 may be increased from'weak' to'medium'. An example of the change in the air volume step according to the pet mode operation is shown in Table 1 to be described later.

In addition, the controller 600 may control the movement of the circulator 300 and rotation in the left and right directions according to the indoor air level. For example, if the indoor air rating is'bad', the circulator 300 is tilted and does not rotate left and right, and if the indoor air rating is very bad, the circulator 300 is tilted and It can be controlled to rotate left and right.

On the other hand, the control unit 600 also the air volume of the second blowing fan 240 and the circulation fan 330, the second blowing fan 240 and the circulation fan operated in the auto mode operation step (S20). 330) can be increased. In this case, since the suction capacity of the first air cleaning module 100 and the second air cleaning module 200 is further increased, contaminants caused by the companion animal can be quickly purified indoors.

On the other hand, as described above, the air purifier 10 may be controlled to improve the collection ability by using the general properties of pollutants caused by companion animals. For example, the rotational speed of the first blowing fan 160 matched with the air volume step may be set to be greater than the rotational speed of the second blowing fan 260.

In addition, in the pet mode operation step (S30), the rotational speed increase value of the first blowing fan 160 may be greater than the rotational speed increase value of the second blowing fan 260. For example, the first blowing fan 160 and the second blowing fan 260 rotate the first blowing fan 160 even if the air volume level is controlled upward from'weak' to'medium' in the same manner. The change value of the speed may be controlled to be greater than the change value of the rotation speed of the second blowing fan 260.

Additionally, the control unit 600 automatically controls the movement of the circulator 300 and rotation in the left and right directions when the user's selection or pre-input conditions are satisfied even when the indoor air rating is'good' or'normal'. You can (this can be called the'booster on' state). Examples of the movement of the circulator 300 and the left and right rotation according to the pet mode operation in the'booster on' state are shown in Table 2 to be described later.

Operation mode Indoor air class Air volume grade Circulator 1st ventilation fan 2nd ventilation fan Circulation fan movement Left and right rotation Auto mode Very bad Turbo Turbo River Second position rotation Bad River River medium Second position fixing usually medium medium about First position fixing good about about stop First position fixing Pet Mode Very bad Air volume Air volume Turbo Second position rotation Bad Turbo Turbo River Second position fixing Normal (booster on) Turbo Turbo River Second position fixing usually Turbo Turbo medium First position fixing Good (booster on) River River medium Second position fixing good medium medium about First position fixing

As a result, the effect of increasing the air volume of the air cleaning module (100, 200) and the circulator 300 during pet mode operation to rapidly inhale hair, dust and pollutants generated from companion animals to improve deodorization performance. There is.

On the other hand, in the pet mode operation step (S30), when a sleep reservation is input or a command to change the driving mode is input while the pet mode is being operated, the pet mode is terminated (S33).

That is, the control unit 600 determines whether the user presses the sleep reservation button 520 to set the sleep reservation while the pet mode is operating, or whether there is an input for changing the driving mode by pressing the driving mode button 530 by the user. (S33), and if there is an input for setting a bedtime reservation or changing the driving mode, the pet mode is terminated and the pet mode is changed to an existing mode before the input of the air cleaning module (100, 200), and the circulator ( 300) and the display device 400 is controlled (S34).

As a result, according to the present invention, when a user enters a bedtime reservation for sleeping, it is possible to prevent noise that interferes with sleeping by limiting the operation of the pet mode.
