The present invention relates to an elevator air purifying and sterilizing technology, and more particularly, to an elevator air purifying and sterilizing system in which an air purifying and sterilizing operation can be actively operated according to a user's elevator boarding situation.

In recent years, elevators have been rapidly supplied according to the high-rise and large-sized buildings, and in the case of buildings exceeding the standards for the number of floors and gross floor area, elevators are required to be installed according to the Building Act. In general, an elevator refers to an elevator, an escalator, a wheel chair lift, and the like, which are means of vertical movement.

In the case of a passenger elevator, like a car, it is a means of vertical movement that is very close to daily life, and it is essential to maintain and manage a pleasant and healthy indoor environment, especially since it is used by a large number of users in an enclosed space. If the air filling the airtight inner space of the elevator car is polluted, it can cause allergies, asthma, eye congestion, headaches and chronic fatigue, as well as various germs and viruses, including the recently popular corona virus. It can be said that there is a high possibility that it will be a channel for propagation.

Accordingly, conventionally, in order to purify the air of the elevator car, a ventilation fan is installed on the outer ceiling of the elevator car to draw outside air into the elevator car.

Korean Patent Registration No. 10-0119656 (1997.08.05) relates to an elevator air cleaning device, in which a ceramic layer emitting far-infrared rays is coated and formed on the inner panel surface of an elevator car and an elevator door, and the lower inner wall of the elevator car After forming an air discharge hole communicating with the outside at a predetermined position of the air discharge hole, a duct leading to the upper part of the elevator along the outer wall of the elevator is connected to the outside of the air discharge hole, and the top of the elevator connected to the duct A plurality of filters, a fan motor that is installed in front of the filter and operated while sucking air inside the elevator, and a filtering means consisting of a housing surrounding them are connected, and the top plate of the elevator corresponding to the rear end of the housing By forming an air blowing hole that communicates with the inside of the elevator at the location, the air inside the elevator is forcibly circulated to the outside and filtered, then re-introduced from the top of the elevator to the inside, and from the elevator and the inner panel of the elevator door. Far-infrared rays are radiated so that the air inside the elevator can always be maintained in a comfortable state.

Korean Utility Model Publication No. 20-1996-0022485 (July 20, 1996) relates to an elevator air cleaning device, and an air discharge hole is formed in the middle of an operation control panel installed in the elevator, and air is discharged through the air discharge hole. As much as possible, a conventional ion generator and filter are installed in the vicinity of the air discharge hole, and a blower is formed on the side of the filter, so that clean air comes out at the height of the respiratory system of the occupant in the elevator, so that you can get on the elevator more quickly. In addition to supplying clean air to people, by installing an ion generator, negative ions beneficial to the human body are supplied to the elevator, so that passengers in the elevator can drink clear and pleasant clean air.
