Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a dust collecting part for an air cleaner,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting part for an air cleaner and, more particularly, to a dust collecting part for an air cleaner and a dust collecting part for collecting charged contaminants. And a separator for separating the electrode plate and the separator plate from each other, thereby reducing manufacturing costs and a manufacturing method thereof.

The air purifier is a device for removing contaminants such as dust contained in the air through electrical attraction.

Such an air cleaner generally includes a charging unit positioned at an inlet side to which air flows and charging a contaminant contained in the air, and a dust collecting unit disposed behind the charging unit to collect the charged contaminants by electrical attraction . The charging section is composed of a discharge wire formed in a wire shape and forming a plus (+) pole and counter electrode plates forming a minus (-) pole spaced apart from the discharge wire by a predetermined distance. The dust collecting section has a plurality of high voltage The collecting electrode plate and the plurality of grounding electrode plates are alternately arranged.

In order to improve the dust collecting efficiency and to provide a compact dust collecting device, the dust collecting part mounted in such a conventional air purifier has been tried to minimize the thickness of the high voltage electrode plate and the low voltage electrode plate. However, due to the reduced thickness, deflection occurs at the center of the electrode plate, thereby exposing the electrode plate to the risk of contact. As a result, it is not easy to provide an electrostatic precipitator having a predetermined size or more.

Korean Patent Publication No. 1525848 is known as a prior art for solving such a problem. In the above prior art, a plurality of high-voltage electrodes and high-voltage electrodes spaced apart from each other are alternately arranged, and the support member is interposed therebetween, whereby the electrode can be prevented from sagging. However, a mounting hole capable of fixing the supporting member must be formed on the low-voltage electrode, and the pair of supporting members must be fastened to each other while passing through the mounting hole at the upper and lower surfaces of the low-voltage electrode. .

On the other hand, the dust collecting plate periodically removes the pollutants collected on the dust collecting plate so that the dust collecting efficiency is not lowered. However, if the water is not completely removed after washing, there is a risk of accident caused by a short circuit, and the air cleaner can not be used during drying. This is because the manufacturing cost of the dust collecting plate such as the conductive material such as metal and the conductive layer is relatively high.

FIG. 1 is an exploded perspective view of an air cleaner according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of an electrode plate according to a preferred embodiment of the present invention, and FIG. 3 is an exploded perspective view of an electrode plate according to a preferred embodiment of the present invention. Sectional view.

As shown in FIG. 1, the air purifier according to the present invention includes a charging unit 100 for charging various contaminant particles contained in air with positive ions, and an air purifier 100 for collecting and removing contaminant particles charged in the charging unit 100 And a dust collecting unit (200). Although not shown in the drawing, the charging unit 100 includes a case into which air containing contaminant particles can flow, a discharge electrode fixedly disposed at a certain distance formed by a plus (+) pole through a power connection terminal, And a counter electrode formed between the discharge electrode and the discharge electrode and formed of a negative (-) electrode. The configuration of such a charging unit corresponds to a known technology, and a detailed description thereof will be omitted.

The dust collecting part 200 is located behind the charging part 100. The dust collecting part 200 collects the polluted particles charged in the charging part 100 and includes the dust collecting part case 210 and the electrode plate part 220 fixedly arranged in the dust collecting part case 210 in the same outer shape as the charging part 100 .

2 and 3, the electrode plate portion 220 is alternately stacked with the high-voltage electrode plate 221 and the low-voltage electrode plate 222 spaced apart from each other by a predetermined distance in order to collect the contaminant particles . The high-voltage electrode plate 221 and the low-voltage electrode plate 222 are electrically connected to a power connection terminal (not shown). Thus, the high-voltage electrode plate 221 is applied with a high voltage so as to have a positive polarity, The electrode plate 222 is grounded to form an electric field.

As a result, when the various contaminant particles in the air are positively charged in the charging unit 100, the positively charged contaminant particles are positively charged by the Coulomb force in the dust collecting unit 200 at a relatively low voltage level The clean air collected in the electrode plate 221 is discharged to the rear.

Here, the high-voltage electrode plate 221, the low-voltage electrode plate 222, and the separator plate 223 are all preferably made of paper, more preferably a flame-retardant paper.

Generally, the electrode plate of the air cleaner has a pair of a high voltage electrode plate 221 made of a conductive material and a nonconductive material surrounding it, and a low voltage electrode plate 222 made only of a conductive material, The same electrode plate in which the nonconductive material covers the conductive material is used for both the low voltage electrode plate 221 and the low voltage electrode plate 222. [

For example, in the case of a high voltage electrode plate 221 made of a conductive material and a nonconductive material surrounding the conductive layer, the conductive layer is electrically connected to the power connection terminal, and the insulation layer is in close contact with the upper and lower portions of the conductive layer. And the low-voltage electrode plate 222 is made of a material having excellent electrical conductivity such as stainless steel or aluminum. Of course, the high-voltage electrode plate 221 having the above-described structure can also be used as the low-voltage electrode plate 222 as described above.

In the present invention, since the high voltage electrode plate 221, the low voltage electrode plate 222, and the separator plate 223 are all made of paper, the manufacturing cost can be remarkably saved as compared with the conventional electrode plate. In addition, unlike the conventional electrode plate, it is possible to easily replace the electrode plate without washing it with water, so that it is possible to eliminate the anxiety due to the washing due to the washing with water and the leakage.

The electrode plate 220 according to the present invention will be described in more detail. The high voltage electrode plate 221 is coated with a conductive ink A in a predetermined shape on one side of the paper, and on the upper surface of the conductive ink A Lay paper again so that all other surfaces are insulated except for the area connected to the high voltage power connector (not shown). On the other hand, the low voltage electrode plate 222 has the same outer shape as the high voltage electrode plate 221, but applies the conductive ink (A) on both sides of the paper in a predetermined shape.

The conductive ink (A) is not applied to the separator plate (223) located between the high voltage electrode plate (221) and the low voltage electrode plate (222).

The high-voltage electrode plate 221, the low-voltage electrode plate 222, and the separator plate 223 having the above-described structure are stacked alternately.

When the separation plate 223 is provided between the high voltage electrode plate 221 and the low voltage electrode plate 222, it is possible to improve the dust collection efficiency of the contaminant particles, It is possible to prevent the electrode plates 221 and 222 from flowing in the dust collecting case case 210. [

Here, although the separation plate 223 is shown as being wavy, it is not limited thereto.

On the other hand, in the case of using the electrode plate of the same structure made of the conductive material and the nonconductive material surrounding it as the high-voltage and low-voltage electrode plates 221 and 222, the conductive ink A is applied in a predetermined shape to one side of the paper And the paper is again laminated on the surface on which the conductive ink (A) is applied, whereby the electrode plate can be manufactured. The obtained electrode plate is laminated in the order of the high voltage electrode plate 221, the separator plate 223 and the low voltage electrode plate 222 in the same manner as described above.

FIG. 4 is an exploded perspective view of an electrode plate according to a modified embodiment of the present invention, and FIG. 5 is a view illustrating a method of using the electrode plate of FIG.

As shown in Fig. 4, the conductive ink (A) is applied on the same surface of the paper so as to be spaced apart at a predetermined interval. Specifically, in the case of the low-voltage electrode plate 222, the conductive ink (A) is applied so as to form two areas on the top and bottom surfaces of one sheet of paper. The conductive ink (A) . After the low voltage electrode plate 222 and the high voltage electrode plate 221 thus prepared and the separator plate 223 are sequentially stacked between the electrode plates 221 and 222 prepared as described above, When cut, the two electrode plate portions 220 can be obtained even in a single operation, thereby saving manufacturing time and cost.

Although FIGS. 4 and 5 illustrate the case where there are two conductive ink (A) regions, it is obvious that three or four conductive ink (A) regions can be changed as needed.

Next, a dust collecting part manufacturing method according to a preferred embodiment of the present invention shown in FIGS. 2 and 3 will be described. First, conductive ink A is applied in a predetermined shape on a top surface of a paper having a predetermined width and area, and then only the area where the conductive ink A is applied is applied to a top surface of the paper, to which a high voltage power connection terminal (not shown) The paper is laminated again so that all the surfaces are insulated, and the high voltage electrode plate 221 is prepared.

The conductive ink (A) is applied in a predetermined shape to the upper surface of the paper having a predetermined width and area at the same time as, or after or before the preparation of the high voltage electrode plate (221), and then the conductive ink Voltage electrode plate 222 is prepared by applying the conductive ink (A) to the rear surface of the paper so that its shape and position coincide with each other.

The separator plate 223 is prepared separately from or simultaneously with the high voltage electrode plate 221 and the low voltage electrode plate 222.

The process of laminating a wavy separator plate 223 on the prepared high voltage electrode plate 221 and laminating the low voltage electrode plate 222 on the wavy separator plate 223 is repeated to obtain a predetermined height Thereby completing the electrode plate portion 220 having the above-

Voltage electrode plate 221 and the low-voltage electrode plate 222 are respectively connected to a power connection terminal (not shown), thereby assembling the dust collecting unit 200 .
