As described above, the fitting frames 110, 112, 210, and 212 are detachably coupled to the outer surfaces of the main body 100 and the auxiliary body 200, and the fitting frames 110, 112, 210, Has a shape and a size that come into close contact with a window frame or a window mirror.

As a result, by appropriately changing only the fitting frames 110, 112, 210, and 212, it is possible to accurately fit any existing window or window frame so that the interior can be reliably sealed and sealed with the outside.

Hereinafter, the operation of the window filter device of the present invention will be described.

5 is a system configuration diagram to which a window filter device is applied.

A sensing sensor 320 is installed in the room. The sensing sensor 320 detects a concentration of carbon dioxide, a concentration of harmful gas (NOx, SOx), or an odor in a predetermined cycle and transmits a sensing signal.

The signal can be transmitted either wired or wireless, and the detection sensor 320 can be installed at a plurality of positions.

The control unit 10 applies the power supplied from the power supply unit 20 to the filter device in accordance with the input of the switching signal from the switch unit 130 or to perform each function assigned to each switch.

The control unit 10 may be a programmed microprocessor, for example, a program for controlling the operation of the fan unit 120 may be embedded.

Basically, the filter device can be manually controlled irrespective of the concentration of carbon dioxide in the room. When the user presses the switch of the switching unit 130 to drive the filter device, the control unit 10 controls the fan unit 120, So that outside air flows into the room.

At this time, the fine dust or harmful substance contained in the introduced outside air is removed while passing through the filter provided in the filter cartridge 171, and only the purified air flows into the room. Therefore, even if the outside air is not clean by the fine dust, fine dust and the like can be removed through the filter and then introduced into the room.

If the concentration of carbon dioxide sensed periodically exceeds a reference value in accordance with a setting criterion, the control unit 10 may control the concentration of the carbon dioxide or the harmful gas to a predetermined level, Drives the fan unit 120 and displays the current state through the LCD 132. [

A negative pressure is applied to the inside of the filter unit by the driving of the fan unit 120 so that outside air flows into the inlet hole 143 of the rear cover 142 and passes through the filter cartridge 171 and then flows upward, And is discharged from the discharge hole 122 to the room through the through hole 183a and the drive fan.

Accordingly, the concentration of carbon dioxide in the room gradually decreases. When the concentration of the carbon dioxide periodically sensed by the sensing sensor 320 becomes lower than the reference value, the control unit 10 controls the fan unit 120 to stop the driving fan.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Accordingly, the scope of the present invention should not be construed as being limited to the embodiments described above, but should be construed in view of the claims set forth below.
