Separated from the surface of the housing 110, the first supply port 115 and the third exhaust port 116 are opened.

When the damper drive motor 193 rotates in the reverse direction due to the stop of the ventilation device 100, the rack 191 moves in the inner direction of the housing 110 due to the reverse rotation of the pinion 192, causing the air supply and exhaust damper 190 to move. By approaching the surface of the housing 110, the first supply opening 115 and the third exhaust opening 116 are closed.

The damper drive motor 193 may be configured as a stepping motor, where one rotation section is divided into a plurality of stems, and the step angle is proportional to the electric pulse signal input to the stepping motor. Accurate rotation angle control can be achieved by rotating in one direction or in the reverse direction.

Through this, the electric pulse signal input to the stepping motor is controlled to make the opening and closing operation amount of the supply and exhaust damper 190 constant, thereby preventing the rotation angle of the damper drive motor 193 from being excessively or insufficiently formed. It is possible to prevent malfunction of the opening and closing of the supply and exhaust damper 190.

In addition, as shown in FIG. 17, a rack guide 194 having a “L” shaped cross section may be formed on the side of the damper connection hole 117 to protrude along the longitudinal direction of the rack 191, and may be formed as “ㄷ”. The inner surface of the "shaped rack guide 194" is spaced apart from the outer surface of the rack 191 to form a gap of a certain size, and guides the direction of linear movement of the rack 191 according to the rotation of the damper drive motor 193. It is configured to do so.

The rack guide 194 improves the straightness of the rack 191 during the opening and closing operation of the supply and exhaust damper 190, so that the engaging portion between the rack 191 and the pinion 192 is aligned with each other as the supply and exhaust damper 190 is tilted. It is possible to prevent malfunction of the opening/closing operation of the air supply/exhaust damper 190 due to misalignment, or damage due to wear or separation between gears of the rack 191 and the pinion 192.

In addition, when the opening operating distance of the supply/exhaust damper 190 is excessive due to a malfunction of the damper drive motor 193, a stopper is formed at the end of the rack 191 to limit the moving distance of the rack 191 by the stopper. It can be.

It can be configured not to form a gear on the surface of the rack 191 near the stopper so that the gear engagement between the rack 191 and the pinion 192 is released while the moving distance of the rack 191 is limited by the stopper, and through this, the stopper Even if the damper drive motor 193 operates in a restricted state of movement of the rack 191, the pinion 192 rotates idle, thereby preventing damage such as wear between the gears of the rack 191 and the pinion 192. .

The operating method of the window-mounted ventilation device according to the embodiment of the present invention configured as above will be described as follows.

When the ventilation device 100 operates, the damper drive motor 193 rotates in one direction and the supply/exhaust damper 190 is spaced apart from the surface of the housing 110, so that the first supply port 115 and the third exhaust port 116 are connected to each other. The opening is made, and the air supply fan 150 and exhaust fan 160 are operated.

By operating the air supply fan 150, the air in the second air supply passage 112 is sucked into the intake port of the air supply fan 150, and the second air supply of the first cover 170 is directly connected to the outlet of the air supply fan 150. It is discharged to the mechanism 172, and thus the outdoor air introduced into the housing 110 through the first air supply port 115 is discharged through the first air supply flow path 111, the air supply filter 141, and the supply and exhaust channel 120. , sequentially passes through the second air supply passage 112, the air supply fan 150, and the second air supply opening 172 and moves to the space between the first cover 170 and the second cover 180.

Outdoor air moving into the space between the first cover 170 and the second cover 180 moves along the air supply area divided by the cover partition 171, and moves to the third air supply opening of the second cover 180 ( 181) and is supplied to the indoor space.

In addition, when the exhaust fan 160 operates, the air in the second exhaust passage 114 is sucked into the intake port of the exhaust fan 160, and the third exhaust port of the housing 110 is directly connected to the outlet of the exhaust fan 160. It is discharged to (116), and accordingly, the indoor air moving to the space between the first cover 170 and the second cover 180 through the first exhaust port 182 is divided into an exhaust area divided by the cover partition 171. It moves along and moves to the first exhaust passage 113 of the housing 110 through the second exhaust port 173 of the first cover 170.

The indoor air moving to the first exhaust flow path 113 sequentially passes through the exhaust filter 142, the supply and exhaust channel 120, the second exhaust flow path 114, the exhaust fan 160, and the third exhaust port 116. It is then discharged to the outdoor space.

At this time, when the supply/exhaust channel 120 is made of a heat exchange element, outdoor air moving from the first air supply channel 111 to the second air supply channel 112 in the supply/exhaust channel 120, and the first exhaust channel 113 ) Heat exchange occurs between the indoor air moving from the second exhaust flow path 114.

When the supply/exhaust channel 120 is composed of a simple channel, as shown in FIG. 14, outdoor air moving from the first air supply channel 111 to the second air supply channel 112 flows through the air supply channel of the supply/exhaust channel 120. The indoor air passing through 121 and moving from the first exhaust flow path 113 to the second exhaust flow path 114 passes through the exhaust channel 122, and the air supply channel 121 and the exhaust channel 122 are connected to each other. Arranged in a physically separated layered structure, ventilation operation is performed without the load generated during heat exchange.

When the ventilation device 100 stops operating, the damper drive motor 193 rotates in the reverse direction and the supply/exhaust damper 190 approaches the surface of the housing 110 and comes into complete contact with it, thereby opening the first supply port 115 and the third exhaust port. (116) is closed, and the air supply fan 150 and exhaust fan 160 stop operating.
