That is, in the positive pressure environment mode, an operation in which outdoor air (A3) is continuously supplied to the inside of the room is performed, and accordingly, the inside of the room is created as a positive pressure environment.

On the other hand, if only ventilation of the bathroom is required other than the above negative pressure environment or positive pressure environment, it can be controlled in the bathroom fan mode.

That is, as illustrated in FIGS. 6 and 7 , when the required environmental mode is the bathroom fan mode, the mode control unit operates the opening/closing damper 200a of the room air intake 111 and the opening/closing damper 200c of the outside air intake 113. ) are controlled to be closed, respectively, and only the opening/closing damper (200b) of the bathroom air inlet (112) is controlled to be opened.

In addition, the air (A2) sucked through the bathroom air inlet 112 is discharged from the discharge case unit 120 while controlling the operation of the transfer path switching damper 600 so that it is transported along the sub transfer path S.F. The passage controls the operation of the discharge passage switching damper 500 to be created toward the exhaust outlet 121 .

As above, when the opening and closing dampers 200a, 200b, 200c, the discharge passage switching damper 500 and the transfer passage switching damper 600 are operated by the control of the mode control unit, as illustrated in FIG. 6, from the outdoors The intake of external air and the intake of internal air from the room are blocked, respectively, and only the internal air (A2) of the bathroom is sucked in.

And, as illustrated in FIG. 7 , the sucked internal air A2 of the bathroom is transported along the sub-transport passage S.F by the passage change of the transfer passage switching damper 600, and thus the filter member 400 While passing through the blower 300 directly without passing through, the exhaust is discharged to the outdoors through the exhaust outlet 121.

That is, in the bathroom fan mode, only the internal air (A2) of the bathroom is exhausted to the outside, and the bathroom is ventilated. will prevent
