Abstract
PURPOSE: To enable exhaust and suction to be changed over to each other by changing over shutters, by interlockably providing a suction port shutter to change over the suction air suction port and the exhaust air suction port and a discharge port shutter to change over the suction air discharge port and the exhaust air discharge port.
CONSTITUTION: With a suction air suction port 12 closed by a suction port shutter 15 as well as a suction air discharge port 14 closed by a discharge port shutter, when a fan 8 is rotated by means of a motor 9 by operating a switch properly, the air sucked by the fan 8 is allowed to flow from the room through an exhaust air suction port 11. Moreover, the exhaust air is discharged to the outside of the room from an exhaust air discharge port 13 through a vent hole 3 and a duct 2. Under said condiction, when a pull 24 is lowered, the shutter 15 opens the suction air suction port 12 and closes the exhaust air suction port 11 as well as through a connecting rod 19, the shutter 16 is changed over so as to open the suction air discharge port 14 and close the exhaust air discharge port 13. Thereby, the suction of the outdoor air is performed.
