摘要： PROBLEM TO BE SOLVED: To provide a less-expensive air cleaner having a high insulative characteristic as regards an electrical power supplying contact element fixing section. SOLUTION: An insulator 52 and an insulating plate 53 are combined and fixed to a fixing surface 47 connected to the ground. An insulating space 54 is defined between the insulator 52 and the insulating plate 53. A head part 57a of a bolt 57 having an electrical power supplying contact element fixed thereto is exposed out in the insulating space 54. A rib 60 at the inner surface of the insulator 52 enters a concave groove 72 of the insulating plate 53 with a predetermined clearance and then the rib 70 of the insulating plate 53 enters a concave groove 61 at the inner surface of the insulator 52. With such an arrangement as above, it is possible to elongate an extending surface distance from the bolt head part to the fixing surface along the surface of the insulating plate and further to assure an insulating distance. It is also possible to eliminate filler material.

摘要： PURPOSE: To improve the efficiency of electrifying dust in air to prevent a self-excited vibration phenomenon of an electrode wire by arranging the elec trode wire close to an one counter electrode plate and installing a member for restricting an air flow between another counter electrode and the electrode wire. CONSTITUTION: An electrode wire 1a is arranged to one counter electrode 22 at a prescribed distance X from a central position C of a pair of counter electrodes 21, 22. Thus the combined force F of electrostatic forces generated between the electrode wire 1a and the counter electrode plates 21, 22 acts so that the amplitude of the electrode wire la may be restrained. Therefore, minute displacement generated in the electrode wire 1a is immediately attenuated and does not reach self-excited vibration. On the other counter electrode 21 side far from the electrode wire 1a, corona current is decreased. Further, since the flow of air passing between the counter electrode plate 21 and the electrode wire 1a is restricted by a flange part 21b, the flow velocity of air flowing between them is retarded. Thus the electrifying efficiency of dust for the whole ionization device is improved.

摘要： PURPOSE:To make the improvement of dust collecting efficiency and the restraint of pressure loss be compatible with each other by holding each dust collecting part body by a frame body with a clearance allowing the flow of air from a dust collecting air flow passage on the upstream side to that on the downstream side being divided. CONSTITUTION:A top plate frame 223 and a bottom plate frame 229 are set in the air flow direction so that they may each be longer than electrode plates 211, 212 by a dimension B at both the ends. In this way, between a dust collecting air flow passage PS of one dust collecting part body 210 and a dust collecting air flow passage PS of the other dust collecting body 210, a clearance C is divided at the time of continuous setting. By this constitution, the dust collecting air flow passages PS of the dust collecting bodies 210, 210 each communicate with the dust collecting flow passages PS through the clearance C. As a result, air that has passed through an ionizing part 10 is introduced into the air flow passage PS on the downstream side from the air flow passage PS on the upstream side through the clearance C. Therefore, pressure loss is effectively restrained even when a clearance 53 of the air flow passage PS is narrow.

摘要： PURPOSE: To provide an electric insulating material, by which no deterioration in surface potential is caused in varied use circumstances, and to stabilize dust collecting cfficiency by using this electric insulating material for a dust collecting electrode for an air cleaner. CONSTITUTION: Volume resistivity of an insulating resin film coating a conductive material such as aluminum is controlled from 3.0×10 to 9.0×10 Ω.cm, so that a reduction rate of surface potential of the insulating film is suppressed. The volume resistivity is controlled by mixing ethylene vinyl acetate(EVA) copolymer to a polyvinyl chloride(PVC) resin film or by adding denatured polypropylene, an antistatic agent, a conductive filler, or a low volume resistivity polymer to a polypropylene(PP) resin film.

摘要： PURPOSE: To facilitate attaching and detaching operations and mounting of a dust collecting body by guiding a frame material into both side frames in the state of averting the interference at the time of attaching and detaching electrical parts and the dust collecting section body in such a manner that the frame material is mounted in these side frames only in the normal posture. CONSTITUTION: This element includes the guiding members 221B, 221C for guiding the frame material 223 into both side frames 221 in the state of averting the interference at the time of attaching and detaching the electrical parts 305 and the dust collecting section body 210. The frame material 223 allows the dust collecting section body 210 to be mounted in the side frames 221 only in the normal posture. As a result, the dust collecting section body 210 is attached and detached to and from the side frames 221 in the state of prohibiting the interference with the electrical parts 305 at the time of attaching and detaching the dust collecting section body 210 to and from the side frame 221. The frame material 223 is commonly used as a regulating means for allowing the dust collecting section body 210 to be mounted in the side frames 221 only in the normal posture and, therefore, the frame material 223 and the guiding members 221B, 221C prohibit an error in mounting in case the posture of the dust collecting section body 210 relative to the side frames 221 is wrong.
