PURPOSE:To make a uniform air-conditioning in a room by adjusting an inner cone vertically. CONSTITUTION:An inner cone 3 can be adjusted vertically. When the inner cone 3 is elevated, the outer cone air flow and the inner cone air flow are blown out of the outer cone air passage 5 and the inner cone air passage 6 in the downward direction. When the inner cone is lowered, the outer cone air flow is blown out of the outer cone air passage 5 in the downward direction and the inner cone air flow is blown out of the inner cone air passage 6 in the horizontal direction. In this way, since the inner cone air flow pushes the outer cone air flow, an air flow is created in a room by combining the inner cone air flow with the outer cone air flow and the air flows in the intermediate zone also, uniform air-conditioning is obtained in the room. |
