DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention applies a high voltage to a space between a plurality of first electrode plates disposed inside a housing and a second electrode plate disposed between the first electrode plates. The present invention relates to an electric dust collection cell for collecting dust.

[0002]

2. Description of the Related Art An electric dust collecting cell applies a high voltage between electrode plates and collects dust in the air by electric force. In an electric dust collection cell, such dust and the like adheres to the electrode plate and reduces dust collection efficiency. Such a dust collection cell is cleaned by, for example, immersing it in a predetermined cleaning liquid for a predetermined time and then washing with water. After washing in this manner, the electrode plate is dried until no moisture such as water droplets remains on the electrode plate. Then, after drying, it can be attached to the original place and dust collection can be resumed.

FIGS. 10 (a) and 10 (b) are a side view and a top view showing a conventional electric dust collecting cell, and FIG. 11 (a) is an electric dust collecting cell shown in FIG. 10 (a). It is a side view which simplified the dust collection cell. In the figure, 101 is an electric dust collection cell, and 111 is its housing. 112

Next, the operation will be described. First, when dust is collected by the electric dust collecting cell 101, the first electrode plate 112a and the second electrode plate 11
2b, a predetermined high voltage is applied, and dust in the air charged in advance is collected by electric force. Note that the circuit described earlier in Japanese Patent Application Laid-Open No. 5-31398 can be used for the high voltage application unit.

When the electric dust collecting cell 101 is washed, it is immersed in a predetermined cleaning solution as described above, and then the electric dust collecting cell 101 is dried. As shown in FIG. 11A, the electrode plates 112a and 112b of the electric dust collection cell 101 are provided in parallel with the outer surface 151 of the housing 111, so that the entire outer surface 151 contacts the ground.

2b becomes horizontal, and the water adhered at the time of cleaning becomes difficult to flow down. Therefore, when the electric dust collection cell 101 is dried, as shown in FIG. 11B, the support 201 is inserted between the outer surface 151 and the ground, and the electrode plate 112a,
By inclining the 112b, the attached moisture can easily flow down.

[0006]

Since the conventional electric dust collection cell is constructed as described above, at the time of drying after washing, the support 201 is inserted between the outer surface 151 and the ground. In addition, by inclining the electrode plates 112a and 112b, it is necessary to make it easy for attached moisture to flow down.
Depending on the shape of the support 201, the electric dust collection cell 101 can easily fall down, and the support 201 is prepared and the outer surface 1
There is a problem that the drying operation becomes complicated because it is necessary to insert between the 51 and the ground.
