- IR infrared rays
- the light reflecting member 120 is configured to reflect only ultraviolet rays (UV) having a short wavelength and allow infrared rays (IR) having a long wavelength to pass
- the lamp member 110 is configured to pass ultraviolet rays (UV) and infrared rays (IR).
- ultraviolet (UV) is reflected, but infrared (IR) passes through the light reflecting member 120, and the passed infrared (IR) heats the catalyst (C). It becomes.
- infrared rays (IR) passing through the light reflecting member 120 heat the heat conductive member 211, and the high temperature heat is transmitted through the heat conductive member 211 to the heating member 210 It is transferred to and raises the temperature of the catalyst (C).
- the heating member 210 may use a general heating member 210 such as a heating wire.
- infrared rays IR that have passed through the light reflecting member 120 are transferred to the post-processing flow path 220 to increase the temperature of the catalyst C. That is, the sterilization flow path 130 and the post-treatment flow path 220 are overlapped, but when the post-processing flow path 220 is arranged to surround the sterilization flow path 130, the infrared rays (IR) passing through the sterilization flow path 130 Since the catalyst C provided in the post-treatment flow path 220 is heated, it is possible to maintain the activation temperature of the catalyst C even if a separate heating member is not provided.
- FIG. 5 is a cross-sectional view showing the air flow inside the sterilization device according to another embodiment of the present invention.

That is, the catalyst C is provided in both the post-treatment flow path 220 and the extension flow path 230, and the sterilized air containing ozone passes through the post-treatment flow path 220 and the extension flow path 230 in sequence.
- the path through which ozone is decomposed becomes longer, so that air can be discharged in a state where ozone is decomposed reliably.
- At least one end of the front end of the sterilization unit 100 or the rear end of the post treatment unit 200 may be provided with a blower 500.
- the blower 500 may generally be a fan driven by a motor, but any device may be used as long as it is a means for generating blown air.

Abstract
La présente invention concerne un dispositif de stérilisation pouvant décomposer l'ozone et, plus particulièrement, un dispositif de stérilisation pouvant éliminer un contaminant même dans une condition d'écoulement d'air à grande vitesse, et pouvant également décomposer l'ozone généré pendant un processus de stérilisation. À cet effet, la présente invention concerne un dispositif de stérilisation comprenant : une unité de stérilisation composée d'un canal d'écoulement à travers lequel s'écoule de l'air d'admission, et d'un élément de lampe destiné à émettre des rayons ultraviolets de façon à stériliser l'air d'admission traversant le canal d'écoulement ; une unité de post-traitement destinée à décomposer l'ozone compris dans l'air ayant traversé l'unité de stérilisation ; et un élément réfléchissant la lumière disposé à l'opposé de l'élément de lampe et entre lesquels est interposé le canal d'écoulement de façon à réfléchir les rayons ultraviolets émis depuis l'élément de lampe vers le canal d'écoulement.
