DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting electrode of an air purifier for collecting dust by charging dust.

[0002]

2. Description of the Related Art Conventionally, this type of dust collecting electrode has been configured as shown in FIG. Hereinafter, the configuration will be described.

As shown in the figure, an insulating-coated conductor 1 has a long strip-shaped first conductive material 2 coated on both sides with an insulating material 3, and the insulating-coated conductor 1 and a strip-shaped second conductive material 4 are coated. Are arranged one after the other at regular intervals, and the first conductive material 2 and the second
By applying a DC high voltage of several kV between the conductive materials 4, the charged dust particles are collected by Coulomb force. Further, in order to reliably apply a high voltage to the strip-shaped first conductive material 2 in the insulating coated conductor 1, at least one surface of the insulating material 3 coated on both surfaces of the first conductive material 2 is peeled off, The metal plate 5 is caulked to the exposed first conductive material 2 with a metal rivet 6 or the like, and a high voltage is applied through the metal plate 5.

[0004]

In such a conventional dust collecting electrode, both surfaces of a long strip-shaped first conductive material 2 are covered with an insulating material 3.
And a strip-shaped second conductive material 4
Are continuously stacked at regular intervals, and if the dust collection electrode is formed by winding or winding, the connection of the conductive portion is sufficient at two places, but the insulating coated conductor 1 and the second conductive material 4 are connected. In the case of a dust collecting electrode formed by cutting and stacking to a predetermined length, a connection of a conductive part is required for each layer, and there is a problem that a manufacturing method becomes complicated and a material cost increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to simplify the current collection and structure so as to be easily manufactured and to be inexpensive.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an insulated conductor in which both surfaces of a strip-shaped first conductive material are covered with an insulating material and cut to a predetermined length. A conductor and a strip-shaped second conductive material having substantially the same length are sequentially superposed at a predetermined interval, and a portion of the cut portion of the insulating covering conductor where the first conductive material is exposed; The problem solving means is that a planar elastic material having conductivity is brought into contact with an end of the second conductive material.

[0007]

According to the present invention, an elastic material
The repulsive force causes the entire insulation-covered conductor to come into contact with the elastic material.
Strip the insulating coating from the insulated conductor to expose the conductor.
Issued to it is unnecessary, and a high voltage metal plates and metal rivets for applying is not required, thereby reducing the simple material cost manufacturing.

[0008]

An embodiment of the present invention will be described below with reference to FIG.

As shown in FIG.
Is obtained by cutting a long strip of first conductive material 9 having both surfaces covered with insulating material 10 into a predetermined length. The strip-shaped second conductive material 11 has substantially the same length as the insulative-coated conductor 8, and the insulative-coated conductor 8 and the second conductive material 11 are arranged one above the other at regular intervals. Elastic material 12
Is in contact with the exposed portion of the first conductive material 9 on the cut surface of the insulating coating conductor 8 and the end of the second conductive material 11, so that current is collected through the elastic material 12. I have to. Therefore, the first conductive material 8 of each insulating-coated conductor 8
Thus, a high voltage can be reliably applied to each of the second conductive members 11 and dust can be collected.

Next, another embodiment of the present invention will be described with reference to FIG. The components having the same configuration as the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG.
Reference numeral 3 denotes a first exposed portion of the first conductive material 9 of the cut surface portion, which is several millimeters in the longitudinal direction, and further exposed a resilient material 12 having conductivity.
Is pressed against the conductive material 9 and the second conductive material 11 to surely contact with each other to collect current. In order to expose the first conductive material 9 on the cut surface portion of the insulated conductor 13 to several mm in the longitudinal direction, the insulating material 10 is peeled off by a construction method, or a heat-shrinkable insulating material is used as the insulating material 10. Then, by applying heat, the insulating material on the cut surface is contracted, and the first conductive material 9 on the cut surface is exposed several mm in the longitudinal direction.

As is apparent from the above embodiments, according to the present invention, an insulated conductor in which both surfaces of a strip-shaped first conductive material are coated with an insulating material and cut to a predetermined length, and the insulated conductor is provided. And a strip-shaped second conductive material having a length substantially the same as that of the insulating-coated conductor is disposed on the portion where the first conductive material is exposed, and 2 of the conductive material of the end portion in the flat resilient member having conductivity, respectively those
Contact with the entire insulation-covered conductor due to the repulsive force of the elastic material.
The elastic material comes into contact, and thus the insulating material covering the first conductive material.
There is no need to peel off the edge coating , a high voltage can be reliably applied between the first conductive material and the second conductive material and dust can be collected, and the structure and manufacturing are simple and the material cost is reduced. it can.
