Description

Elevator with disinfection function and easy cargo transportation {ELEVATOR WITH DISINFECTION FUNCTION AND EASY CARGO TRANSPORTATION}

The present invention relates to an elevator equipped with a disinfection function and easy to transport cargo.

Elevators are installed in high-rise buildings so that people and cargo can be easily moved from the bottom to the top. Elevators have become an essential device in high-rise buildings such as residences, schools, hospitals and offices. On the other hand, an elevator is used by a large number of people in a limited space for a certain period of time in a state of being close to each other. However, if the inside of the elevator is not periodically sterilized and ventilated, viruses, bacteria and fine dust may be collected inside the elevator, which may cause problems in the health of elevator users.

That is, it is necessary to periodically sterilize and ventilate the interior of the elevator to disinfect the interior of the elevator. However, in order to disinfect the inside of the elevator, there is a inconvenience in that the user of the elevator must be disinfected through a safety agent for disinfection after stopping the time period or when the elevator is stopped. In addition, the disinfection of the inside of the elevator carried out by safety personnel cannot be a detailed prevention, and in particular, it is difficult to be a continuous prevention. For example, even if security personnel perform disinfection once or twice a day, the elevator may be contaminated by an infected person who visits after disinfection. In addition, disinfection work by safety personnel has a disadvantage in that quarantine costs such as labor costs are excessively generated.

As a prior art for solving the above problems, there is Republic of Korea Patent Registration No. 10-2207978 (registered on January 20, 2021). The present prior art relates to an elevator automatic quarantine device capable of maximizing the prevention effect through automatic spraying of a disinfectant solution through a sprayer provided inside the elevator. The elevator of the prior art is equipped with a motion sensor, and when the elevator does not move for a certain period of time, it transmits a signal to the injection controller and the sprayer sprays the disinfectant solution inside the elevator.

However, the elevator automatic quarantine device of the present prior art is inconvenient to be equipped with a motion sensor in the elevator. In addition, since a device for discharging the air inside the elevator to the outside is not separately provided, the air inside the elevator may be stagnant without being circulated.

In addition, when cargo and moving goods are transported through the elevator, a box or panel is temporarily attached to the inner wall to protect the inner wall of the elevator and used. However, it is inconvenient to bring a protective material to be temporarily used whenever a load is transported, attach it using a tape, etc., and then remove it and discard it or take it back after transport. In addition, when a used box or panel is reused, it is difficult to completely protect the inner wall of the elevator, so even though a protective material is attached, scratches and damage to the inner wall may occur.
