On-floor mount type air filtering apparatus

Abstract

An on-floor mount type air filtering apparatus to remove bacteria is equipped with a gas-liquid contact member (5) that is disposed in an on-floor mount type housing (2) and formed of material having little reactivity to electrolytic water, an electrolytic water dropping unit (17, 5C) for dropping electrolytic water to the gas-liquid contact member (5), and an air blowing fan (7) for blowing indoor air to the gas-liquid contact member (5). The housing (2) has an air suction port (3) provided at the lower portion thereof and an air blow-out port (4) provided at the upper portion thereof, and the indoor air sucked from the air suction port (3) by the air blowing fan (7) is brought into contact with the electrolytic water dropped to the gas-liquid contact member (5) and blown out from the air blow-out port (4).

Description

technical field [0001] The present invention relates to, for example, a portable vertical air sterilization device capable of removing airborne microorganisms and viruses. Background technique [0002] In general, for the purpose of removing airborne microbial viruses and the like, air cleaning devices have been proposed which capture viruses such as influenza virus or mold floating in the air or bacteria (hereinafter referred to as viruses, etc.) and remove these viruses, etc. Inactivation or sterilization (hereinafter referred to as inactivation, etc.) filter (for example, JP-A-08-266828). In such an air sterilizing device, a filter to which tea extract is added is disposed, and germs and the like captured by the filter are mainly inactivated by the action of tea polyphenols contained in the extract. [0003] In addition, as a device for the same purpose, there is known a sterilizing device that diffuses electrolyte mist in the air and makes airborne microorganisms direct...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned sterilization device, tea polyphenols are gradually detached from the surface of the filter due to oxidative decomposition over a long period of time.

Therefore, since the function of the filter to inactivate germs and the like is gradually reduced, when the filter is used for a long time, there is a possibility that the germs and the like captured by the filter will fly again with activity.

[0005] In addition, although the latter sterilizing device can be effective in a small space where the electrolyte mist is easy to reach, it can be used in environments where the electrolyte mist is difficult to reach, such as kindergartens, universities, middle schools, and nursing homes. It is difficult to be effective in large spaces such as insurance facilities and hospitals
