In addition, the human body detection sensor 170 may transmit the sensed signal to the control unit.

The controller receiving the signal from the human body detection sensor 170 determines that the user intends to pass through the window 15 and shortens the blind unit 150 to open the area covered by the blind unit 150. [

If the detection signal is not received from the human body detection sensor 170 for a preset time after the blind unit 150 is shortened, the control unit determines that the user has completely passed the window 15, and the blind unit 150 The blind unit 150 can cover the area where the window 15 is opened.

Through the interlocking of the human body detection sensor 170 and the blind unit 150, the user can conveniently pass through the window 15.

4, when the blind unit 150 is operated in a ventilation mode with the blind unit 150 being extended, the ventilation unit 100 according to an embodiment of the present invention includes the outdoor side discharge port 113, An air curtain type air current is discharged from the indoor air outlet to the indoor air outlet, thereby preventing indoor air from being introduced into the indoor space and improving indoor air discharge speed.

Specifically, the air curtain airflow can generate a high flow velocity behind the blind unit 150. [

At this time, when the slat member 155 of the blind unit 150 is inclined as shown in FIG. 4, room air can be discharged to the outside space between the slat members 155. In this case, the air pressure on the outdoor side of the slat member 155 is lowered by the air flow of the air curtain, and as a result, the room air can be discharged through the slat members 155 at a high speed.

While the present invention has been particularly shown and described with reference to particular embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention as defined by the following claims I would like to make it clear.
