• a first discharge unit having a first discharge flow path formed therein;
• a second discharge unit having a second discharge flow path formed therein;
• a first centrifugal fan for blowing air to the second discharge flow path;
• and
• a second centrifugal fan having an air duct disposed at the front of the first centrifugal fan,
• wherein an air passage for guiding air into the first discharge flow path is formed between the air duct and the outer surface of the first centrifugal fan,
• wherein each of the first and second centrifugal fans includes:
• an impeller;
• and
• a scroll housing surrounding the impeller, the scroll housing having suction hole and discharge hole formed therein,
• wherein the scroll housing includes:
• a base plate;
• a scroll wall connected to the base plate, the scroll wall being formed in a scroll shape from an cutoff;
• and
• a discharge wall extending from the scroll wall,
• wherein a flow path extending portion having a flow path sectional area extending toward an air flow direction convexly protrudes in the outer direction of the scroll housing in the base plate.
