摘要： PURPOSE: To increase the sound consuming effect in a filter unit by inter posing the air path holding materials between the gaps of filter medium, holding these with a rectangular frame and providing the gaps of the filter medium slantingly for the air current direction.
CONSTITUTION: A filter unit 46 is constituted of a rectangular frame 48 and filter mediums 50,52 folded in 99 times are set together with the zigzag space holding materials 53 which are interposed between the gaps thereof in the inside of the fame and the gaps are slanted in 30 for the air current direction shown by an arrow A. The air current is flowed along the flow path in chevron between the filter mediums 50, 52 and the essential component of sound wave is passed through the same passage as air current and therefore the noise is consumed by the flex of the filter mediums.

摘要： PURPOSE: To reduce the number of parts by a method wherein a plurality of base plates arranged parallel to one another leaving gaps among the adjoining edges of the plates, respectively, are used as ceiling plates and the adjoining edges of the plates are placed on ceiling crosspieces provided at the lower ends of suspenders hung down from the ceiling so that the gaps among the adjoining edges of the base plates form themselves air blowout ports.
CONSTITUTION: A plurality of suspenders 44 are hung down from the wall of the ceiling and the ceiling crosspieces 46 attached horizontally to the lower ends of the suspenders 44. The ceiling crosspiece 46 is formed of a ceiling plate laying section 46A and a suspender fixing section 46B and the corners of each of the base ceiling plates 50 are placed on the ceiling plate laying section 46 so that the gap 52 is formed between each two adjoining ceiling plate 50 so as to serve as the air blowout port. In addition, the ceiling crosspiece 46 is in the form an elongated plate having an elongated hole 70 through which air is blown out.

摘要翻译：目的：通过一种方法减少部件数量，其中分别平行布置的多个基板分别在板的相邻边缘之间留下间隙，作为顶板，并将板的相邻边缘放置在天花板上悬臂的下端设置有从天花板悬挂下来的挡板，使得底板的相邻边缘之间的间隙自身形成空气喷口。构成：多个悬吊件44从天花板的墙壁悬挂下来，并将天花板横件46水平地附接到悬挂件44的下端。天花板横档46由天花板铺设部分46A和悬吊固定部分 46B，并且每个基座顶板50的角部被放置在天花板铺设部46上，使得间隙52形成在每个两个相邻的顶板50之间，以用作吹气口。此外，天花板横档46形成具有细长孔70的细长板，空气通过该长孔70吹出。
