AI Technical Summary

Technical Problem

Existing disinfection methods for elevator cabins do not provide automated and safe germ reduction, as they lack activation based on the absence of persons and are not integrated with elevator systems to ensure safety.

Method used

A disinfection device with a radiation source, control unit, and safety device that activates only when the elevator car is empty, using sensors to detect absence of people, and deactivates upon door movement or presence detection, integrated as a retrofit module for existing systems.

Benefits of technology

Ensures automated and safe germ reduction in elevator cabins by activating radiation only when empty, preventing exposure to radiation when people are present, and integrating seamlessly with existing elevator systems.

Description

1. Technical field

[0001] The invention relates to the fields of elevator technology and building hygiene.

[0002] It concerns a device for the automated disinfection of elevator cabins using radiation to reduce germs in the air and / or on surfaces. 2. State of the art

[0003] Disinfection methods based on chemical cleaning agents or manual cleaning are known. Furthermore, radiation sources for germ reduction are generally known.

[0004] A disinfection device coupled to an elevator system is not known to exist in such a way that activation only occurs when the elevator car is empty and is automatically deactivated when the door moves or presence is detected. 3. Object of the invention

[0005] The object of the invention is to provide a disinfection device that enables automated and safe germ reduction in elevator cabins.

[0006] In particular, it should be ensured that the radiation source is only activated when the absence of persons is detected. 4. Solution to the task

[0007] The problem is solved by a disinfection device with the features of claim 1.

[0008] The device includes: • at least one radiation source for germ-reducing treatment of air and / or surfaces, • a control unit, • a safety device coupled to the elevator system to prevent activation when people are present.

[0009] The safety device includes sensors to detect when the elevator car is empty.

[0010] The control unit is designed in such a way that the radiation source is only activated when an empty state is detected.

[0011] The radiation source is automatically deactivated when the door is moved or presence is detected.

[0012] In one embodiment, the radiation source is designed as a UVC radiation source.

[0013] In another embodiment, the radiation source is arranged in a closed housing.

[0014] In another embodiment, a motor-operated flap or aperture is provided that covers the radiation source.

[0015] The device is designed as a retrofit module for existing elevator systems. 5. Example of implementation

[0016] In a preferred embodiment, the radiation source is designed as a UVC radiation source. The device is connected to the elevator control system.

[0017] After a defined period of time without detected movement or load, a disinfection cycle is started.

[0018] The cycle is immediately interrupted when a door is opened or movement is detected. 6. List of reference symbols 1 radiation source 2 Drive unit (motor) 3 Aperture 4 cases
