Abstract: An inner portion of a filter cleaning portion 300 arranged at an inner portion of an interior unit is respectively arranged with cleaning units 300A, 300B constituted by arranging upper brushes 344a, 344b brought into contact with one face of an air filter and lower brushes 322a, 322b brought into contact with other face of the air filter 5 opposedly to each other at filter inlet/outlet 350a, 350b of the filter cleaning portion 300. Further, a longitudinal frame 54 and a transverse frame 55 of an air filter 5 having a filter sheet 51 in a shape of a meshed sheet for catching dust and a frame 52 for supporting the filter sheet 51 are formed on a rear face side (side of heat exchanger 3) of the filter sheet 51.

Abstract: In an air conditioner having a main body provided with a panel 1 including a front panel 1a and a top panel 1b, the main body incorporating an air passage connecting an air inlet 2 and an air outlet 3, an air filter 4, a heat exchanger 5, a blower fan 6, and a dedusting device 7 attached to the front face of the air filter 4 which is reciprocated along the surface of the air filter 4, the top panel 1b is opened/closed as the dedusting device 7 is reciprocated.

Abstract: The present invention relates to a method and apparatus for charging a high-viscous material in a material tank into a charging tank. The high-viscous material, namely, putty is used preferably as a material for correcting the dynamic unbalance of a rotary body. When the material is charged from the material tank into the charging tank through a nozzle, the pressure of air in the charging tank is reduced and the pressure of air in the material tank is increased to drop the high-viscous material in droplets without taking air thereinto and air which has permeated into the material in the material tank can be removed.
