DESCRIPTION

Device for the automatic disinfection of elevators with ozone

Description

Device for the automatic disinfection of the interior of the cabins for the different models of lifting devices, maintaining the safety of the users since its operation begins when the device is free.

From that moment on and through the dosage and control of the appropriate ozone reversal time, it disinfects the cabin in a short period of time and keeps it disinfected for its next use.

Background of the invention

Ozone (O ³ ) is a substance whose molecule is composed of three oxygen atoms, formed when the two atoms that make up oxygen gas dissociate. Each released oxygen atom binds to another gaseous oxygen molecule (O ² ), forming ozone molecules (O ³ ).

Ozone is one of the most powerful oxidants known and is commercially produced from oxygen. This characteristic as an oxidant makes it a very interesting agent for disinfection in different industrial processes.

Ozone is characterized by its low stability since its decomposition is spontaneous, this makes it necessary to generate ozone in the same place where it is going to be used. It is precisely this spontaneity that we will use as the basis of our invention, the time it takes for ozone to decompose back into oxygen is the time we call Reversion Time and it will be the time that allows us to control the operation of the device in the different states of job.

The ozone generators in the state of the art are the following:

^or US6287431 describes a constant pressure ozone generator comprising a series of electrolytic molecules.

^o US6372096 refers to a system for regulating the pressure in different ozone generating lamps.

^o EP 3333125, ES 1174333 U, ES 1012131 U, ES 537.685, ES 325.195, ES 2247 379 T3, ES 2676311 T3, ES 2283175 B1, ES 1229374 U, refer to the different existing devices that are or use Ozone generators intended to other services that do not need production control, reversal control, presence detectors, timings, security measures or auxiliary inputs and outputs for the control of the elevator's own elements. For example: control of the opening of doors, being able to keep them closed and with the elevator without service until its activation by our device with the option of combining it with a signaling system to the outside that will show the operating status of the elevator device.

Currently existing devices:

^{o They do} not provide a specific system to be able to install them in the cabin of any lifting device, regardless of the model / manufacturer.

^{o They do} not contemplate the possibility of employing a complete and complex system for use in places with human traffic.

^{o They do} not provide control over the operation of the device in an intelligent way, but rather it does so in a pre-programmed or continuous way.

^o They do not self-adapt to the needs created in their environment, thus not achieving the best optimization of the work system, electricity consumption and consequently contribution to the environment.

^o They are not optimized in the generation of the precise amount of ozone to produce disinfection in small spaces. So that in a minimum period of time enough ozone is generated for disinfection.

^o They are not designed to optimize the reversion time (the time it takes for ozone to become oxygen again) once the disinfection time is over, our device begins to count the reversion time of ozone in the environment to proceed with the new one. use of space.

To solve these problems, the application for this utility model provides:

^o The adaptation of its design to the installation on any elevator device cabin, having direct ozone output to the cabin, through an easy-to-install device and access to the entire mechanism, thus facilitating maintenance tasks.

^o Command and detection system for the self-management of the mechanism itself in an intelligent way through the data that arrives thanks to the sensor incorporated in the chassis or in the lift itself (if it already exists previously, for example sensors to control the consumption of lighting in the cabin, it could be used so as not to increase the cost of the device). Once the data has been received according to the defined parameters, the control system will develop the most optimal work rate for each moment, thus achieving an economical and sustainable operation.

^o Lastly, it enables the external control of the lift's own operation to be developed at the same time or independently, through auxiliary inputs and outputs self-commanded by the command and detection system and / or, where appropriate, signaling.

The applicant does not know of any solution similar to the invention.

Description of the invention

This invention refers to a device intended for automatic disinfection for the interior of the cabins of the different models of lifting devices, maintaining the safety of the users, its operation begins when the device is free, in that moment through the dosing and proper ozone reversal controlled by the device, it disinfects the cabin in a short period of time and keeps it disinfected for its next use.

This device controls the ozone generation and reversal time, this period of time can be programmed in an interval of 2 to 600 seconds, thus adapting to the size of the space to be disinfected and thus ensuring that the stop time of the elevator is the minimum possible.

The device will incorporate in its interior the modules for capturing its own or other people's signals that will determine its operating mode. This signal capture will be carried out by means of a complex system composed of sensors, timers and the automatic control of all of them.

The form of action of this device will be as follows: using its own or third-party presence sensors, it will detect when it is being used, it will allow a time for the departure of people and in any case the new activation will be able to start the waiting time again until confirm the idle status of the elevator. As soon as the sensors indicate that the lifting device is at rest, the control and detection system will give the signal to start the ozone generation / production cycle, during this cycle the oxygen molecules in the air are transformed into ozone and poured into the cabin for disinfection. Once the ozone production is finished and naturally due to the instability of the produced molecule, the reversion time begins (time in which the ozone molecules are converted back into oxygen). During the generation and reversal times, the device will keep the elevator blocked or, where appropriate, signaled to prevent the passage of people, thanks to its command and detection system, the device is designed to work according to the flow diagram summarized in Fig. 6 and create the different states with the information received from its sensors and act according to the previous parameterization. Once the reversal time is over, the device will go to rest and start the ozone generation cycle again when the sensors indicate it. The device of the invention also has safety systems (redundant systems, elevator entrance control, auxiliary inputs and outputs for external control), off switch, as well as a safety mechanism in case of failure of some of its components, avoiding always uncontrolled ozone generation.

In summary, the four main working states of our invention are:

• Elevator status detection

• Ozone generation

• Reversion to oxygen

• Rest

To clarify our device and see its design in the different models of lifting devices that exist today. We are going to integrate them into two groups depending on the construction characteristics of your roof, specifically if the lifting device has a false ceiling or not, that is, if the roof seen from inside the cabin is the same as the roof of the lift We will say that it does not have a false ceiling and otherwise it does have a false ceiling.

• For elevators that do NOT have a false ceiling, the device will be housed on the outside of the ceiling using damping rubbers (25). The neck (22) that protrudes from the cover of the device will be fitted through a hole in the ceiling, thus allowing the ozone exit through the direct circular opening (23) and thus avoiding unnecessary movements and adjustments, being able to place inside the cabin some kind of trim grille.

• For elevators that DO have a false ceiling, the device will also be housed on the outside of the ceiling. Taking into account the uniqueness that the false ceilings in most elevators are not hermetically closed but rather have a perimeter opening for assembly and disassembly of the same, in our case this uniqueness will be used so that the ozone discharge to the The cabin is made using the non-centered or offset design of the direct circular opening (23) and to be able to house it in a corner of the ceiling and thus make the most of the ozone output.
