Problems solved by technology

However, if a plate-shaped ground electrode is used, the discharge space is limited to a relatively small space, so some dust particles that move quickly with the air circulation generated by the fan 110 may not have an attached charge
In the ionizer 104, the dust particles without charge cannot be collected by the collecting body 106, thereby increasing the filtering burden of the final filter 108 arranged behind the electric dust collecting device

Embodiment Construction

[0022] The examples illustrated in the drawings are used as a reference for detailed description of the preferred embodiments of the present invention, wherein the same elements are given the same reference numerals.

[0023] Figure 2 to Figure 6 The preferred embodiment of the air purifier of the present invention is described in detail. figure 2 A perspective view of the air purifier of the present invention is shown. Such as figure 2 As shown, a cover 204 is provided on the front surface of the main body 202 of the air purifier, and a plurality of suction ports 204a are provided on the cover 204 to suck external air into the main body 202. That is, through the suction port 204a, air containing pollutants is sucked into the main body portion 202, so the function of the main body portion 202 is to eliminate pollutants such as dust particles, thereby filtering the air. The filtered air is discharged to the outside through an exhaust port (not shown) provided at the rear of the ...

Abstract

An air purifier has a simply manufactured and assembled ionizer (304), which increases the charging efficiency for dust particles through maximally increased discharge spaces and prevents electrical accidents. The air purifier includes an ionizer (304) and a collector (306). The ionizer (304) includes two ground electrode units (402a,b) and at least one discharge electrode (410), the two ground electrode units (402a,b) each having one or more electrodes (408), each formed in a hollow semicylindrical shape. The two ground electrode units (402a,b) are joined to face each other, with the at least one discharge electrode (410) being placed in spaces formed between the hollow semi-cylindrically shaped electrodes (408) of the joined ground electrode units (402a,b). Dust particles are charged as they pass through the spaces between the hollow semi-cylindrically shaped electrodes (408). The collector (306) is electrically charged with a polarity opposite to a polarity of the charged dust particles.

Description

[0001] Cross reference with related applications [0002] This application claims priority for Korean Patent Application No. 2002-82868 filed at the Korean Intellectual Property Office on December 23, 2002, and the disclosure of which is hereby incorporated by reference. Technical field [0003] The present invention generally relates to an air purifier, and more particularly to an air purifier including an electric dust collecting device capable of charging dust particles in the air and collecting the charged dust particles. Background technique [0004] Those of ordinary skill in the art are well-known that air purifiers are used to remove dust, bacteria and pollutants from the air and then provide clean air after purification. This air purifier is provided with an electric dust collecting device for collecting dust and other substances. In the electric dust collecting device, the dust particles charged by the corona discharge of the ion generator are collected by the electrosta...
