The present invention relates to a plug-type type air cleaner. In particular, the present invention purifies and sterilizes indoor air contaminated by harmful electromagnetic waves generated from indoor air and electronic devices contaminated by various pollutants in the atmosphere, by simply plugging in all outlets using AC power. The present invention relates to a plug-in type air cleaner that maintains air continuously.

In general, the excessive pollution of the pollutants, the air environment is polluted, the air is heavily polluted by indoor air or smoking or various pollutants, and the air infected with bacteria is often present in the room.

In particular, there is a high possibility that bacteria are present in indoor air at places such as hospitals and laboratories. Such indoor pollution is known to adversely affect the human body mentally and physically.

In order to solve the above problems, conventionally, anion generating air cleaners are used for purifying indoor air in homes and offices. The negative ion generating air cleaner applies a high voltage to the discharge electrode that charges the fine particles in the air with a positive polarity (+) or a negative polarity (−), and a grounding electrode having a polarity opposite to that of the discharge electrode to the dust collecting electrode where charged dust is collected. A device for collecting various dust suspended in the air, for example, a discharge occurs between a discharge electrode using a positive electrode (+) as a ground electrode and a dust collecting electrode generating a negative high voltage. The strip is attached to the dust collecting electrode, and various dusts charged from the discharge electrode to the positive electrode (+) adhere to the dust collecting process and at the same time, a large amount of negative ions are generated at the collecting electrode to remove harmful cations and ozone.

Therefore, the conventional air cleaner uses a corona discharge method that ionizes the surrounding air with a large amount of electrons generated by charging the dust collecting electrode and the discharge electrode, and a lot of dust is stacked on the dust collecting electrode having the negative electrode. Since the strip is smaller than the dust collecting electrode but considerable dust sticks to the discharge electrode, periodic cleaning of the discharge electrode and the dust collecting electrode is required to prevent the performance of the air cleaner. However, since the dust collecting electrode and the discharge electrode of the above-described air cleaner are fixedly mounted inside the case of the air cleaner, cleaning of the dust collecting electrode and the discharge electrode is very difficult and inconvenient, and due to the expansion of the installation space, the overall volume of the device must be enlarged. There was no.

In order to solve the above problems, the 'negative ion generation air purifier' of Korean Utility Model Registration No. 0178327 has been developed, but this structure separates the grille, the filter, the dust collecting electrode and the discharge electrode which are mounted on the front of the purifier case. In addition to the inconvenience of cleaning, using a narrow gap of the discharge electrode to clean one by one because the discharge electrode is difficult to clean more difficult.

In addition, 'Negative ion generating air purifier with a removable dust collecting plate' of Korean Unexamined Patent Publication No. 2001-0017510 has been manufactured and marketed, but this also has only a dust collecting electrode detachable, so the discharge electrode is not cleaned, so the discharge efficiency is reduced. There is a problem.

The present invention for solving the conventional problems as described above is simply plugging the air cleaner in the form of a plug into a home or office outlet, indoor air contaminated with various pollutants such as harmful electromagnetic waves and smoking generated from various electronic devices The purpose is to purify and recover the negative ions reduced by pollution to maintain clean and fresh indoor air.
