Air cleaning apparatus

Abstract

There is disclosed an air cleaning apparatus usable regardless of seasons, weather, environmental conditions and the like. The air cleaning apparatus brings air to be treated into contact with a cleaning solution including active oxygen species to purify the air to be treated includes a water tank which stores the cleaning solution, and a temperature controller which controls a temperature of the cleaning solution stored in the water tank. The temperature controller includes a heat exchanger as a cooling / heating unit which cools or heats the cleaning solution stored in the water tank, and controls the temperature of the cleaning solution into 0 DEG C. or more to 40 DEG C. or less.

Description

technical field [0001] The present invention relates to an air cleaning device for removing harmful substances or dust contained in the air to be treated. Background technique [0002] In recent years, with the spread of high-density and high-insulation housing, chemical allergy-type health diseases are increasing. The chemical substances that cause the allergies include substances such as formaldehyde that originate from indoor building materials such as walls and wallpaper, and substances that flow in from the outside, such as exhaust gas. As a device for removing chemical substances contained in such air, water that is purified by bringing a cleaning solution containing active oxygen species such as hypochlorous acid and ozone generated by electrolytic technology into contact with the air to be treated has been developed. Cleaning type air purification device. [0003] The above-mentioned air cleaning device, compared with the conventional filter-type air cleaning devic...

Problems solved by technology

[0005] However, in such a water-cleaning type air cleaning device, when water freezes in winter and severe winter (especially below freezing point), it is impossible to generate active oxygen species and diffuse active oxygen species generated by electrolytic technology, so there are The problem of not being able to purify the air

[0006] On the other hand, when the device is used in summer and tropical regions, the performance of the device called water washing, because the treated air becomes high-humidity air containing a lot of moisture, so there is a problem that the user is not happy. question

In addition, the solubility of harmful substances in the treated air decreases with the increase of water temperature, so there is also a problem that the removal efficiency of harmful substances in the treated air decreases.

[0007] Therefore, it is difficult to use the conventional water-cleaning type air purifiers in environments where water freezes in the above-mentioned winter and severe winter seasons, as well as in summer and tropical regions.
