Description

TECHNICAL FIELD [0001] The present invention relates to an air cleaning apparatus using plasma,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier, and more particularly, to a wall-mounted air purifier capable of minimizing a volume and hanging it on a wall.

With the development of industrialization, population density and the increase of vehicles, urban air pollution by smog, exhaust gas, volatile organic compounds such as benzene, toluene, tobacco smoke, fine dust and various chemical substances is increasing, Various respiratory diseases are also on the rise.

An air purifier for purifying the air against such air pollution is commercially available. The air purifier has a basic structure such as a fan (FAN) for sucking and exhausting air and a filter installed at the front end where air is sucked.

The filter usually employs a prefilter for collecting large particles of dust, an activated carbon filter for adsorbing gas in the air and an odor, and a hepafilter for filtering out bacteria. In addition, an odor A negative ion method is also proposed.

As this type of air cleaning apparatus, a technique of mounting an air duct on the front end of a circulating fan is disclosed in Korean Patent Registration No. 10-1457444 (hereinafter referred to as "Citation 1").

There is a problem that the air duct may cause resonance to the vibration of the fan and the air vibration at the air duct intake.

The above problem will be described in more detail with reference to FIG.

The resonance or resonance phenomenon occurs when the length of the air duct corresponds to an integral multiple of 1/2 of the vibration wavelength. 1, the vibration frequency corresponds to the vibration of the fan, that is, the rotation of the pen, and is caused by the vibration of the air at the inlet of the air duct.

Since the rotation of the fan is variable, it is very difficult to design the air duct so that resonance does not occur in various use environments where the vibration frequency is variable.

Such a resonance phenomenon may cause a problem that the noise of the fan itself is further enlarged.

Further, since there is a distance from the air inlet to the fan by the air duct, the thickness of the air purifier must be increased, which is not suitable for being attached to a wall.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic diagram illustrating the problems of the prior art.
2 is a perspective view of an air purifying apparatus according to an embodiment of the present invention.
3 is a cross-sectional view of a section AA of FIG. 2.

As described above with reference to FIG. 1, when there is a vibration source generating vibration, resonance due to resonance may occur in a pipe structure such as a pipe, a cylinder, and a duct. shall.

The present invention proposes an air purifying device which does not generate a resonance phenomenon because it does not have a tube structure and thus can easily design the structure, and also has an air purifying function which can be used by attaching / mounting to a vertical structure such as a wall, Device.

2 and 3, an air purifying apparatus according to an embodiment of the present invention will be described in detail.

And a housing 130 that is made of a solid material such as plastic or metal to form an outer surface of the air purifying device and includes inlets 131 and 132 for introducing outside air into the side surface of the housing.

When the high voltage is applied to the high voltage electrode, the plasma unit 110 discharges the ground voltage to the ground electrode to generate an ion cluster, To remove contaminants.

The ion cluster can generate an anion and then generate a hydroxyl group (OH-) by using the generated anion, thereby antimicrobial effect against bacteria can be expected.

Details of the ion cluster and the plasma unit for generating the ion cluster are disclosed in Korean Patent Laid-open No. 10-2005-0017985, and a detailed description thereof will be omitted.

The ion clusters generated by the plasma unit 110 are directed to the outside of the air purifier through the air outlet 141 included in the housing cover 140 covering the housing 130 along the air flow generated by the exhaust fan 120 And is discharged.

Preferably, the plasma unit 110 should be disposed adjacent to the exhaust fan 120, and one, two, or three or more of them may be disposed in the air discharge direction of the exhaust fan 120.

The ion clusters generated by this arrangement can be discharged to the outside of the housing 130 along with the air flow generated in the exhaust fan 120.

A control unit (not shown) electrically connected to the exhaust fan 120 and the plasma unit 110 for controlling the fan rotational speed of the exhaust fan 120 and adjusting the applied voltage of the plasma unit 110 according to an external environment and a user's operation 160).
