PURPOSE:To enable equipping one apparatus with functions as a ventilating fan and a circulator by moving a stabilizer toward a periphery of a cross fan. CONSTITUTION:A whirl is generated by rotation of a cross flow fan 1. In case a stabilizer 2, made movable toward periphery of a cross flow fan 1, is in a position shown by means of a solid line, air flows in a streamline as a ventilating fan flowing in from an inlet 5 communicating with the exterior of a chamber and flowing out through an outlet 6 as shown by a solid line. Then, in case the stabilizer 2 is moved to a position shown by a dashed line, since the whirl W is stabilized on a guider 4a side, the whirl has a tendency toward generating a drawing flow from a nearer position. This results in generation of a flow as shown by the dashed line, that is, a flow as a circulator absorbed from and discharged to the interior of a chamber. Accordingly, one apparatus may be equipped with functions of a ventilating fan and a circulator only by means of moving the stabilizer 2. |
