<p>PURPOSE:To change the direction of wind with a simple construction by changing the wind flow sent from the blowing-out opening formed in the periphery of the upper surface of frame body into the flow of peripheral direction with the ventilating part formed between the cover body covering a lighting body and the frame body. CONSTITUTION:There are provided the blower unit consisting of an electric motor 19 and blower blades 27, and the cleaning body 7 removing the contaminants in the air. In the frame body 2-5, the blower unit and the cleaning body 7 are built in, and a suction opening 31 and blowing-out openings 22 are respectively formed in the lower part and in the periphery of upper surface. The lighting body 17 is formed in the center of the upper surface of the frame body, and the cover body 6 covers the lighting body 17 and the upper surface of the frame body, and the ventilating part 58 is formed between the cover body and the periphery of the upper surface of the frame body. Consequently, the wind blown out from the blowing-out opening formed in the periphery of the upper surface of the frame body is changed into a peripheral flow through the ventilating part formed between the cover body covering the lighting body and the upper surface of the frame body. Thus, the direction of wind is changed with the simple construction.</p> |
