Description

The air purifiers incorporating IoT technology

The present invention relates to an air purifier incorporating IoT technology. More specifically, as an air purifier that can check the air cleaning function in real time, it displays the status of the air quality of the indoor environment in real time through a display in numerical or graphic or voice to check the air cleaning efficiency, and remotely through a portable terminal. It relates to an air purifier incorporating IoT technology that can control power on/off.

As the modern society enters, the amount of fine dust in the atmosphere increases rapidly due to various complex problems that pollute the atmosphere such as industrial dust, automobile smoke, and yellow dust, and the number of days that the amount of fine dust contained in the atmosphere increases beyond the recommended standard. As a result, it interferes with daily life and adversely affects people's health due to heavy metals contained in fine dust.

In addition, if the window is opened to ventilate dust or carbon dioxide scattered from indoor activities in the home, contaminated fine dust including heavy metals may enter into the atmosphere, and asthma and allergies may degrade the air quality of the indoor space. It can also cause diseases such as bronchitis and pneumonia.

Accordingly, harmful substances such as dust scattered in the indoor air, fine dust including heavy metals introduced from the outside, dust, dust mites, mold, and viruses are collected to purify contaminated indoor air and discharge clean air to create a pleasant environment. Various types of air purifiers that can be formed have been released and commercialized.

Existing air purifiers mainly use a wet air cleaning method in which dust particles are collected by spraying fine water molecules into the inhaled air and filtered through a filter.

However, the existing wet air cleaning method sprays moisture into the air inhaled into the air in a fine form, and foreign substances and water molecules are combined by contact and deposited, and the purified air is discharged. Moisture-bearing dust entangles with each other, and the dust directly blocks the ventilation hole on the surface of the filter, obstructing the flow of circulating air.As the usage period after cleaning increases, the overall efficiency of the air purifier decreases, and high moisture and impurities become entangled. There is a problem in that conditions in which bacterial growth is active are created, and the quality of the air discharged due to the growth of harmful bacteria decreases.
