Description

Elevator with UV sterilization device and UV sterilization method inside the elevator

The present invention relates to an elevator equipped with a UV sterilization device and a UV sterilization method inside the elevator. In particular, the present invention relates to an elevator equipped with a UV sterilization device and a UV sterilization method inside the elevator.

In the case of multi-unit houses and buildings such as apartments, row houses, and villas, the most polluted place is the elevator used by everyone moving in the apartment building or building.

Although an elevator has an open and closed door, it is a place for all residents to enter and exit, and since it is a closed space with the doors closed during entry and exit, the interior space is inevitably polluted when a sick person or a person with bacteria gets on the elevator.

In addition, when a healthy person rides a contaminated elevator, germs can get on their clothes or body. Nevertheless, the reality is that there is no device that sterilizes harmful germs or bacteria present in the interior space of the elevator.

In addition, since most of the elevator passageways have a structure that cannot be cleaned, various pollutants such as dust and insect corpses such as mosquitoes have accumulated over a long period of time in the elevator passageways, and the air inside is also considerably polluted.

In addition, since the blower installed on the upper part of the elevator serves to forcibly circulate the air inside the elevator passage into the elevator, it can be said that the air inside the elevator is more polluted than the outside.

In the case of contamination of elevators, which are multi-use facilities, a space sterilization method that meets various situations and conditions is required.

UV rays are effective in sterilizing various new viruses, house dust, mites, and bacteria.

UV sterilization can sterilize up to 99.9% of bacteria and viruses within a few seconds, and it can effectively remove almost all bacteria and viruses, and does not generate residual substances such as chemicals, so it does not cause secondary pollution of water bodies and surrounding environments. , its use is increasing due to the small area of sterilization equipment and simple structural requirements, as well as low operating and maintenance costs.

However, in order to obtain a sterilization effect in a short waiting time (several seconds to tens of minutes) without using an elevator, a high-power UV lamp with a wavelength of 253.7 nm or more must be used. Therefore, there is a problem that there is a risk to sterilize by directly irradiating UV rays in a space where people enter and exit frequently, such as a room where life is made using UV rays or an elevator.

In order to prevent indoor air pollution described in Korean Utility Model Registration No. 20-0397497 due to this problem, a technology for an air chamber equipped with a sterilizing UV lamp has been developed.
