Description

Handrail for an elevator equipped with a sterilization device and an elevator having the same

The present invention relates to a handrail (safety handle) installed inside a cage of an elevator and an elevator having the same, and more particularly, a sterilization capable of maintaining a comfortable air inside the cage of the elevator by sterilizing and circulating the air inside the cage. It relates to a handrail for an elevator equipped with a device and an elevator having the same.

As the elevator is used by a large number of users within the enclosed space of the cage, it should be managed to maintain a more pleasant and safe indoor environment for the health of users. At the same time, outside air is introduced to the inside to circulate the inside air of the cage.

However, the air circulation method inside the cage using the existing ventilation system has limitations in air purification. The reason is that the hoistway in which the cage is vertically raised is also a closed space, and the pollutant cannot be removed by simply circulating the air present in the sealed hoistway. That is, once generated, various bacteria or viruses cannot be sterilized, but flow into the inside of the case as it is, increasing air pollution.

Pollution of the air inside the cage by various bacteria or viruses is a very important problem in elevators for medical facilities such as hospitals. In the case of elevators for medical facilities, not only patients but also general passengers who enter for care or visits are used together, so they are vulnerable to infection and spread of various viruses and bacteria. Therefore, a facility capable of real-time air sterilization is required in order to prevent infectious diseases.

In prior documents such as domestic registered patent No. 10-0668938 and domestic registered patent No. 10-0789954, an ultraviolet sterilization device forcibly circulates the internal air of the cage using a blower and a ventilator installed on the ceiling of the cage. was sterilized using However, this method is difficult to manufacture and install because the structure is complicated because the UV sterilizer must be installed on the ceiling of the cage. there may be

Korean Patent Application Laid-Open No. 10-2021-0133515 proposes an air sterilizer that is mounted or mounted on a handrail (safety handle) installed inside a cage so that installation and management are relatively easy compared to a structure installed on the ceiling. However, in the structure proposed in Korean Patent Application Laid-Open No. 10-2021-0133515, the duct for transporting and discharging sterilized air to the inside of the cage is installed to protrude to the outside with a certain size, thereby threatening the safety of users such as the disabled and small children. and may also impair the internal aesthetics of the cage.

In addition, Korean Patent Laid-Open No. 10-2021-0138421 proposes a sterilization unit that irradiates ultraviolet or infrared rays to a handrail installed inside a cage. However, in Korean Patent Application Laid-Open No. 10-2021-0138421, the sterilization unit is installed on the outside of the handrail installed inside the cage. It may threaten the safety of users such as children.

Moreover, in the case of Korean Patent Laid-Open Patent No. 10-2021-0133515 and Korean Patent Publication No. 10-2021-0138421, the actual installation is difficult because the 38 pie handrail disability regulations and 50 mm separation distance from the cage wall cannot be satisfied when installing the elevator. It is difficult, and the allowable area is not met due to an increase in volume, which may cause variations in the number of occupants (occupants) of the cage.
