BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

First Embodiment In FIG. 1, reference numeral 1 denotes a main body of an air cleaner. Inside the main body 1, a discharge electrode 3, a filter 5, a counter electrode 7, a deodorizing filter 8 and a cross flow fan 9 are provided. 1
Reference numeral 1 denotes a front cover, and when the front cover 11 is removed, the discharge electrode 3 is exposed at the front. As shown in FIG. 2, a suction port 13 is opened in the front cover 9, and dirty air containing dust enters the main body 1 through the suction port 13 as shown by a solid arrow in FIG. The air flows in, selectively flows as shown by a solid arrow or a dotted arrow as described later, is filtered by the filter 5, and is blown out as clean air from the air outlet 15 or the air inlet 13 of the main body 1.

According to this embodiment, as shown in FIGS. 2 and 3, a plastic holding frame 21 for holding the filter 5 is provided, and the holding frame 21 has four corners as shown in FIG.
As shown in, the protrusions 21a are integrally provided. A flat plate-shaped counter electrode 7 is attached to the holding frame 21 so as to fit into the projections 21a at the four corners. The flat plate-shaped counter electrode 7 is fixed to the holding frame 21 by fusing the projections 21a at the four corners. To be done. The counter electrode 7 is provided with a plurality of holes 7a.

The holding frame 21 is detachably attached to the main body 1 of the air cleaner, and particularly when the holding frame 21 is attached and detached, the discharge electrode 3 is in a direction in which the discharge electrode 3 does not interfere. It is configured to be freely drawn below the main body 1 of the cleaner.

When the holding frame 21 is attached to the main body 1 of the air cleaner, the counter electrode 7 is electrically connected to the electric contact 23 connected to the high voltage power source (not shown) as shown in FIG. According to this, the holding frame 21 is attached to the main body 1 of the air cleaner.
The electrical connection is completed simply by attaching the slide type, so that the attachment is performed with one touch.

Second Embodiment As another embodiment, although not shown, the filter 5
It is also possible to provide a holding frame 21 for holding the discharge electrode 3 and the holding electrode 21 integrally holding the discharge electrode 3 and the counter electrode 7, and to attach the holding frame 21 to the main body 1 in a detachable manner. .
In this case, almost all of the discharge electrode 3 including the discharge electrode 3 is to be removed from the main body 1. Therefore, the direction of removing them may be such that they are removed in front of the main body 1.

Third Embodiment Referring to FIG. 5, the main body 1 is formed of a front cover 101 and a rear cover 103. The front cover 101 is removable, and the front cover 1
When 01 is removed, the discharge electrode 3, the filter 5, and the counter electrode 7 remain on the rear cover 103 side and are exposed to the front. In this way, by removing the front cover 101, the discharge electrode 3, the filter 5, and the counter electrode 7 are integrally exposed there, so that a hand can be inserted between the discharge electrodes 3 to face the counter electrode. Maintenance such as cleaning of 7 can be easily performed.

Fourth Embodiment As another embodiment, although not shown, the main body 1
Is formed by a front cover 101 and a rear cover 103, and when the front cover 101 is removed, the discharge electrode 3, the filter 5, and the counter electrode 7 are removed together with the front cover 101. You may in short,
