At this time, the ventilation mode, the air clean mode, and the emergency exhaust mode can be operated by the user directly, not by the automatic operation by the controller 190.

First, in the ventilation mode, the controller controls the ventilation damper 114 to open the ventilation hole 104, to control the intake damper 107 to open the ventilation hole 103 so that outside air can be introduced, 134 and the exhaust damper 136 so as to open the exhaust hole 135 and the feed hole 133.

When the ventilation fan 150 operates in the state where the damper is controlled as described above, the indoor air is introduced between the ventilation holes 113 through the ventilation openings 104 and the ventilation openings 104, (120).

The air moved to the floor space 120 moves to the air blowing space 131 through the suction port 143 of the suction space 141 and a part of the air moved to the air blowing space 131 is discharged to the air discharge hole 135. [ And the remaining air is moved to the space 115 between the air supply holes 133 through the air supply holes 133 and is discharged to the room through the air supply unit 105, Is supplied to the room in a filtered state.

At the same time, the outside air is introduced into the intake space through the intake port 103, mixed with the inside air introduced through the intake port 113 through the intake port 113, and passed through the filter 180 The air is moved to the suction space 141 through the floor space 120 and the air is blown by the blowing fan 150 through the air blowing space 131 and part of the air is moved to the space 115 between the air supply holes 133 through the air supply holes 133 And the remaining part of the exhaust gas passes through the exhaust hole 135 to the exhaust space and is discharged to the outside through the exhaust hole 102. [

At the same time, 180), fresh air filtered by foreign substances can be introduced into the room.

At this time, when the exhaust hole 135 is closed by the exhaust damper 136 in the ventilation mode, the outside air can be introduced together without exhausting the inside air, the air inlet 103 is closed by the air intake damper 107, When the air supply damper 134 closes the air supply mechanism 105, all of the inside air can be discharged to the outside through the air discharge opening 102 without introduction of outside air.

On the other hand, in the air cleaning mode, the intake damper 107 closes the intake port 143 by the controller 190, the exhaust damper 136 also closes the exhaust hole 135, and the ventilation damper 114 closes the ventilation hole 113 are opened, and the air supply damper 134 opens the air supply holes 133.

When the damper is set and the blowing fan 150 is operated, the air is introduced through the air vent 104 and the air vent 113 into the air vent 113, To the floor space (120).

The air in the bottom space 120 moves to the suction space 141 and moves to the air blowing space 131 through the suction hole and the air in the air blowing space 131 flows through the air feeding hole 133 And then introduced into the room through the air supply mechanism 105 to continuously supply the indoor air to the room again in a state in which the foreign substances contained in the indoor air are filtered by the filter 180 without introducing the outdoor air and discharging the indoor air .

By continuously circulating only the inside air and filtering the fine dust by the filter 180, introduction of the external fine dust is minimized, and only the fine dust introduced into the room is removed to clean the inside air.

On the other hand, in the emergency exhaust mode, the controller 190 closes the air supply damper 134, the air supply damper 107 closes the air inlet 103, and the emergency discharge damper 174 discharges the air The ball 173 is opened.

When the blowing fan 150 operates in the state where the damper is controlled as described above, the air is introduced into the ventilation hole 113 through the ventilation hole 104 and the ventilation hole 113, and the vented air introduced into the ventilation hole 113 And is moved to the intake space through the intake communication hole 137 communicated with the intake space by the load of the filter 180 rather than the side of the filter 180. [

The air moved to the air intake space is moved to the air blowing space 131 by the air blowing fan 150 through the bottom space 120 and the suction space 141 through the emergency discharge hole 173, The air of the filter 180 moves to the exhaust space through the exhaust hole 135 and is discharged to the outside through the exhaust port 102 and does not pass through the filter 180. Therefore,

Therefore, the ventilation air cleaning apparatus 100 according to the embodiment of the present invention can perform both ventilation and air cleaning without installing an air cleaner and a ventilation device at the same time, so that facility cost is low.

In addition, since the intake, exhaust, supply, and ventilation can be performed by one blower fan 150, power consumption can be reduced, and a large capacity HEPA filter can be installed to improve the removal performance of fine dust , The replacement cycle can be increased.

Further, since it can be installed on the window frame, the installation cost due to embedding in the ceiling can be reduced.
