The present invention relates to a copier having a dust collector, and to prevent dust caused by dust by collecting and discharging dust sucked into the copier or dust generated from the toner of the copier by the electrostatic precipitator.

Conventionally, by using the dust contained in the air or foreign matter generated from the copier toner without a separate discharge device, they accumulate inside the copier, and the copier malfunction frequently occurs due to accumulated dust or toner dust of the copier.

In addition, by leaving the fine dust of the harmful paper suspended in the copy paper or the dust of the copier toner, the user to inhale it, there is a problem that impairs health.

Recently, with increasing interest in the purification of indoor air, a number of related products have been released. Among them, indoor air cleaners are representative.

In the case of the indoor air purifier, a small volume and efficient electrostatic precipitator is used as a means of inhaling and purifying foreign substances suspended in the air.

Although the electrostatic precipitator has various kinds of dust collectors, a corona discharge method suitable for miniaturization of a product is used.

As such, the electrostatic precipitator using the corona discharge is composed of the charging unit 110 and the dust collecting unit 120 in a two-stage structure as shown in FIG. 1, and the charging unit 110 includes a plurality of ground plates 111 and the ground plates. It consists of a tungsten corona wire 112 fixed in the space between the (111), when a high voltage is applied to the corona wire 112 between the ground plate 111 and the corona wire 112 having a potential of 0V Corona discharge occurs to ionize the suspended solids contained in the air passing through the charged part 110.

As is well known, corona refers to a state in which electrons flow innumerably, and corona discharge removes electrons from the atoms in the air (positive corona) or adds them (negative corona). To ionize the suspended particles. The negative corona method is mainly used for industrial purposes because it generates a large amount of ozone, and the positive corona method is used for an air purifier.

The dust collector 120 is composed of a plurality of dust collector plates 121 and a plurality of high voltage plates 122 inserted between the dust collector plates 121 which are connected in parallel with each other and grounded, and when a voltage is applied to the high voltage plate 122. A magnetic field is formed between the high voltage plate 122 and the dust collecting plate 121, and ionized floating particles passing through the dust collecting unit 120 are collected in the dust collecting plate 121 by the magnetic field thus formed.

Accordingly, the present invention has been made to solve the above-described problems, by preventing the accumulation of dust or toner dust inside the copier, preventing the copier failure or error due to foreign matters and at the same time generated from toner dust or paper The purpose of the present invention is to prevent harmful dust from being inhaled by the user and to prevent foreign substances from being discharged inside the copier in the room.
