Abstract

PURPOSE:To prevent the displacement or looseness of conductive layers, by winding the stacked layer with the projections provided on an insulating layer facing inward to form a large space between the conductive layer constituting a stacked and wound dust collecting electrode and the facing insulating layer. CONSTITUTION:The layers 1-4 formed on a first insulating layer 1, a first conductive layer 2, a second insulating layer 3 and a second conductive layer 4 are wound continuously around a take-up shaft with the projections 1a provided on the first insulating layer 1 facing inward. After one turn of the take-up shaft, the second conductive layer 4 is formed on the flat surface of the first insulating layer 1 without the projections, with the stable formation thereon the second insulating layer 3 and the first conductive layer 2 and finally the first insulating layer 1 with the projections 1a facing inward is formed and, since the first conductive layer 2 previously formed is formed stably on the second insulating layer 3, the conductive layers are free from wavy looseness.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dust collecting electrode for an air cleaner or the like that collects dust by charging it.

Prior Art FIG. 3 shows a conventional dust collecting electrode. 31 is a first insulating layer having an upwardly projecting protrusion 31a; 32 is a first conductive layer; 33 is a second insulating layer; It was wound in such a way that it faced outward.

Problems to be Solved by the Invention In the above configuration, the first insulating layer 31, the first conductive layer 32 . Second insulating layer 33. Second conductive layer 34
is wound on the winding shaft, the first insulating layer 31 forms the protrusion 31
a, the tension balance cannot be maintained in the second conductive layer 34 in contact with the protrusion 31a, and the second conductive layer 34 becomes wavy as shown in the figure. As a result, when the winding was completed, the second conductive layer 34 in the central portion changed from wavy to wrinkled, and in some cases even broke. This tendency is particularly noticeable when the second conductive layer 34 is extremely thin.

Means for Solving the Problems In order to solve the above problems, the dust collection electrode of the present invention has at least a first insulating layer, a first conductive layer, a second insulating layer, and a second conductive layer laminated in sequence. A space is formed between one of the first conductive layer and the second conductive layer and an insulating layer opposite to the conductive layer, which is larger than other interlayers. In order to form a layer and provide the space layer, which is the hole, a protrusion processed into one of the first insulating layer and the second insulating layer faces inward.

Effect: With the above configuration, the tension balance is maintained in the conductive layer in contact with the protrusions, and the conductive layer does not become wavy, so that the conductive layer does not break.

Embodiment FIG. 1 is a sectional view of a dust collection electrode showing an embodiment of the present invention. 1 is a first insulating layer, 2 is a first conductive layer, 3 is a second insulating layer, and 4 is a second conductive layer, with the protrusion 1a processed on the first insulating layer 1 on the inside. The above layers are continuously wound around a winding shaft so that the dust collecting electrodes shown in FIG. 2 are formed.

When winding, first the first insulating layer 1. First conductive layer 2. The second insulating layer 3 and the second conductive layer 4 form a stable plane on the winding axis. And the winding shaft is 1
After rotation, the first insulating layer 1, the first conductive layer 2. A second insulating layer 3 and a second conductive layer 4 will be formed, but at this time, first the second conductive layer 4 is a first insulating layer on which a stable surface without protrusions is formed. 1, followed by a second insulating layer 3. Each layer of the first conductive layer 2 is formed as a layer with a stable surface. Finally, the first insulating layer 1 with the protrusion 1a located inside is formed, but the already formed first conductive layer 4 is formed as a stable layer on the second insulating layer 3. Therefore, the wavy state that conventionally occurs in the conductive layer does not occur. In this way, each layer can be continuously and stably wound and formed, and the dust collection electrode can be manufactured efficiently. This method is particularly effective when the thickness of each layer is infinitely thin.

Effects of the Invention As described above, the present invention provides a layered material having a thin conductive layer and an insulating layer, at least one of which has protrusions.
It can be obtained in an extremely uniformly wound state without any deviation, and its industrial value is extremely large.
