<p><P>PROBLEM TO BE SOLVED: To provide a ventilating arrangement for ventilation, which can be applied not only to a cabinet for performing natural ventilation, but also can be satisfactorily applied to conditions where waterproof function is required, and which enables easy change of filters inside the ventilating arrangement from outside the cabinet. <P>SOLUTION: The ventilating arrangement comprises a louver plate 2 for covering a mounting hole 1 from outside, and a dust-proof and insect-proof filter 5 which is placed inside the louver plate 2. The louver plate 2 has a ventilating wall 11 wherein a louver wall 10 is formed so as to have multiple stages, and has a peripheral side wall 12 enclosing the peripheral edge of the ventilating wall 11, which are integrated to each other. In a state where the louver plate 2 is mounted on and fixed to the mounting hole 1, an accommodating space S is retained between the mounting hole 1 and the louver plate 2, into which a filter frame 3 and the filter 5 are accommodated. A loading hole 15 is opened at the lower wall of the peripheral wall 12 so that the filter 5 can be inserted and taken out therethrough. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
