Air purifier

Abstract

The present invention provides an air purifier which comprises an ion generating unit, the ion generating unit comprises a first electrode for generating cation and a second electrode for generating electron to form neutral atom by combining with the cation. The air purifier also comprises: a main body having a suction mouth and an exhaust mouth; a ventilator for exhausting the sucked-air to the exhaust mouth; an exhaust passage formed between the ventilator and the exhaust mouth; the ion generating unit arranged on the exhaust passage comprises the first electrode for generating cation and the second electrode for generating electron to form neutral atom by combining with cation.

Description

technical field [0001] The present invention relates to an air cleaner, and more particularly to a portable air cleaner comprising an ion generating unit having a first electrode generating cations and a second electrode generating electrons for combining with the cations to form neutral atoms. two electrodes. Background technique [0002] Generally, an air cleaner has a plurality of filters for purifying the air and a fan for air circulation, so that the air containing dust and odors can be purified through a plurality of filters through the operation of the fan for air circulation, thereby improving air quality. Devices for ambient air quality. [0003] Recently, an air cleaner having an anion supply mechanism has been developed, which not only has an air cleaning function but also has a function of generating and releasing anions. An example of such an air cleaner is disclosed in Korean Laid-Open Patent No. 2006-0100492. [0004] According to the air cleaner disclosed ...

Problems solved by technology

[0007] However, the air purifier disclosed in Japanese Laid-Open Patent Publication "JP-A-2003-123940" directly discharges hydrogen ions harmful to the human body, so there is a hidden danger that the user's health may be affected by the inhalation of hydrogen ions.

Moreover, because cations and anions are alternately produced on the same electrode, many cations and anions will combine and be offset before they play a bactericidal effect, resulting in a decrease in the bactericidal ability

[0008] Also, since there is no unit for neutralizing odorous components in the air, comfortable indoor air cannot be provided to the user
