This auxiliary motor 280 can assist the power of the blowing motor 230 by rotating the blowing fan 220 together with the blowing motor 230 to improve the function of the air circulator by the blowing fan 220 .

The auxiliary motor 280 may be installed at a position where the pressing cap 240 of the blowing fan 220 is located and fixed to the unit case 210. The auxiliary motor 280 may be fixed to the main body case 110 together with the blowing unit 200, As shown in FIG.

When the blower unit 200 is positioned inside the main body case 110, the auxiliary motor 280 is separated from the pressurizing cap 240 to be pressurized, When the ventilation fan 230 is exposed to the outside of the cabinet 110, the ventilation fan 230 is connected by the cap 240 protruding in the axial direction of the driving shaft by the cap spring 250, .

Here, the auxiliary motor 280 has a rotational speed equal to the rotational speed of the driving motor and the driving shaft in consideration of the size of the main body case 110, but the actual driving force (horsepower) is implemented by an electric motor having a smaller driving force than the driving motor .

The operation and effects of the above-described respective structures will be described.

The air purifier 100 having the air circulator function according to the embodiment of the present invention is characterized in that the wall-mounted portion located on the back surface of the main body case 110 is fixed to a bracket provided on the wall, A display device 300 is coupled to the display fixing part.

When the air blowing motor 230 of the air blowing unit 200 is operated, the blowing fan 220 rotates and the air blowing fan 220 rotates the air blowing fan 220, Air is sucked into the main body case 110 through the main body suction port 111 of the main body case 110.

The air sucked into the main body case 110 is primarily filtered through the filter filter unit 130 and the air passing through the filter filter unit 130 passes through the dust filter unit 150, And the virus or the organic compound is destroyed by the ions generated by the discharge.

The air that has passed through the dust filter unit 150 is sucked through the unit suction port 211 of the air blowing unit 200 and discharged to the main body discharge port 113 of the main body case 110 through the unit discharge port 213.

At this time, since the cap guide 118 is pressurized on the pressure cap 240 and the circulator blade 229 closes the blade groove 225, the centrifugal blade 227 only rotates the main body discharge port And a part of the air is discharged to the circulator hole 215 through the cooling hole 228 of the circulator blade 229 and is discharged through the cooling hole 228 formed on the front surface of the main body case 110 To the display device 300 coupled to the front surface of the main body case 110 to cool the display device 300.

Meanwhile, when the air circulator function is selected through the controller, the unit moving mechanism 170 operates to expose the blowing unit 200 to the outside through the exposure hole 115 formed in the upper part of the main body case 110.

At this time, the unit moving mechanism 170 moves the unit case 210 in such a manner that the moving motor 171 rotates the pinion 173 to move the unit case 210 in which the rack bar portion 219 engaged with the pinion 173 is formed, 200).

When the air blowing unit 200 moves upward, the pressing force of the pressing cap 240 which has been pressed by the cap guide 118 is released, and is moved by the cap spring 250 toward the front of the rotating disk 221 The moving pressing cap 240 rotates the rotating shaft of the circulator blade 229 by the shaft coupling portion 241 and rotates the circulator blade 229 in the blade groove 225 so as to be inclined, Lt; / RTI >

When the pressing cap 240 moves forward of the rotary disc portion 221 by the cap spring 250, the clutch 281 of the auxiliary motor 280, which is positioned in front of the pressing cap 240, (240) is inserted to transmit the power of the auxiliary motor (280) to the blowing fan (220).

When the blowing unit 200 is exposed to the exposure hole 115 of the main body case 110 and the blowing motor 230 rotates the blowing fan 220, air is blown by the blowing fan 220 The air is sucked into the unit intake port 211 of the unit case 210 without passing through the dust collecting filter unit 130 and the dust collecting filter unit 150.

A part of the air sucked into the unit suction port 211 is discharged to the unit discharge port 213 by the centrifugal blade 227 and the remaining part of the air is discharged to the front of the main body case 110 through the circulator hole 215 And circulates indoor air to perform an air circulator function.

At this time, the function of the air circulator can be improved by operating the auxiliary motor 280 together with the air blowing motor 230 so as to further improve the output power of the air blowing fan 220, thereby further discharging the air.

Since the direction regulating plate 260 is rotated by the regulating plate motor 270 in the circulator hole 215, the air discharged to the circulator hole 215 is not discharged in one direction but is dispersed and discharged in various directions , Air can be circulated quickly by mixing.

On the other hand, when the user selects the air cleaning function again through the controller, the air blowing unit 200 exposed to the outside of the main body case 110 slides into the main body case 110 by the unit moving mechanism 170 The air blowing unit 200 inserted and inserted moves the circulator blade 229 that has opened the blade groove 225 while the pressing cap 240 is pressed against the cap guide 118 to rotate the blade groove 225 So that air is sucked and discharged only by the centrifugal impeller 227, thereby purifying the air.

Here, when the pressing cap 240 is pressed by the cap guide 118, the pressing cap 240 is released from the clutch 281 of the auxiliary motor 280 to block contact with the auxiliary motor 280, The power loss of the blower motor 230 due to the power contact of the blower motor 280 can be blocked.

Accordingly, the air purifier 100 having the air circulator function according to the embodiment of the present invention can purify the air by the filtering filter unit 130 and the dust filter unit 150, To the outside of the main body case 110 to perform the function of the air circulator.

In addition, the blower fan 220 in the form of a centrifugal fan can be changed to an axial fan by rotating the circulator blades 229 by the blade rotating unit when the blowing unit 200 is rotated up and down to perform the function of the air circulator The centrifugal impeller 227 and the circulator impeller 229 are blown at the same time to disperse the air in various directions to improve the function of the air circulator.

In addition, when the air blowing unit 200 is exposed in the main body case 110, the auxiliary motor 280 rotates the blowing fan 220 together with the air blowing motor 230 to improve the output of air.
