<p>PURPOSE:To make it possible to maintain an air cleaner in a good operating condition and, increase the flow rate of an air with the reduction of a noise level. CONSTITUTION:A fixed frame 28 is fixed between the front plate 26 and the rear plate 27 of a corresponding thin-formed case 21, and a bracket 29 for holding a dust collector is supported, in a freely tilting manner, on the fixed frame 28. In addition, an electrically driven fan 33 is provided above the dust collector 30 and guide plates 34a, 34b are provided between the fan 33 and an outflow aperture 32. Further, the lower part of the bracket 29 is supported by a bolt 31, and the upper part is engaged, in a freely openable manner, by an engagement means. The depth of the upper part 51 of the fixed frame 28 is made to be smaller than that of bottom 52. Thus, it is possible to provide maintenance services by tilting the dust collector 30. A flow path 56 between the rear face of the dust collector 30 and the rear plate 27 of the case 21 is enlarged toward the fan 33, so that the pressure loss of an air in the flow path 56 decreases.</p> |
