Description

Elevator car degassing unit

Technical Field

The invention relates to the technical field of elevator maintenance, in particular to an elevator car disinfection device.

Background

An elevator is a vertical elevator powered by an electric motor and equipped with a box-like car for carrying people or cargo in a multi-story building. There are also steps, where the tread plates are mounted on a track for continuous operation, commonly known as escalators or moving walkways. A fixed elevator apparatus serving a predetermined floor. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15. The size and the structural form of the car are convenient for passengers to access or load and unload goods. It is customary to use elevators as a generic term for vertical transport means in buildings, irrespective of their drive mode. According to the speed, the elevator can be divided into a low-speed elevator (less than 1 m/s), a high-speed elevator (1-2 m/s) and a high-speed elevator (more than 2 m/s). The hydraulic elevator begins to appear in the middle of the 19 th century and is still applied to low-rise buildings until now. In 1852, e.g. austs in the united states developed a safety hoist for wire rope hoisting. In the 80 s, further improvements were made to the drive means, such as motors driving the winding drum via a worm drive, the use of counterweights, etc. At the end of the 19 th century, friction wheel transmission is adopted, and the lifting height of the elevator is greatly increased.

Along with the improvement of the life quality of people, the elevator is more and more widely used and gradually becomes a tool for riding instead of walk for modern buildings, people are sent to a target floor through the up-and-down movement of the elevator car in a hoistway, and time and labor are saved. Buildings provided with vertical lifting elevators are generally high-rise buildings, car armrests are generally arranged in cars of the elevators, people often lean against the inner walls of the cars when taking the elevators, respiratory infectious diseases (such as new coronavirus) are easy to spread in a droplet or hand way, the cars of the elevators are in a closed environment, air is difficult to circulate, fine saliva falls in the cars, and the viruses are likely to be directly attached to the inner surfaces of the cars of the elevators or be turbid in the air in the cars; in order to block the transmission path of the spray or the hand, it is necessary to sterilize the inside of the elevator car and to kill germs in the car.
