DISPOSITIVO ROBOTIZADO PARA DESINFECCIÓN POR LUZ UV Y VENTILACIÓN ROBOTICIZED DEVICE FOR DISINFECTION BY UV LIGHT AND VENTILATION
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un dispositivo robotizado para desinfección por luz UV y ventilación, el cual aporta características estructurales y constitutivas, que se describen en detalle más adelante, que suponen una mejora del estado actual de la técnica dentro de su campo de aplicación. The invention, as expressed in the title of this specification, refers to a robotic device for disinfection by UV light and ventilation, which provides structural and constitutive characteristics, which are described in detail later, which imply an improvement in the state current state of the art within its field of application.
Más en particular, el objeto de la invención se centra en un dispositivo que se configura como un sistema robotizado capaz de desplazarse de manera autónoma y que lleva a bordo un mecanismo de luces ultravioletas para desinfección de superficies combinado con un sistema de recirculación de aire, el cual permite dos modos de trabajo: desinfección de superficies por radiación directa y de aire por recirculación forzada, aunando todas las ventajas de los sistemas actuales en uno sólo, con la ventaja añadida de poder utilizarse de manera segura incluso en entornos donde haya personas y animales, ya que dicho sistema de luces UV puede quedar oculto, afectando únicamente a las partículas forzadas a pasar por el interior del dispositivo gracias al sistema de recirculación de aire. More particularly, the object of the invention focuses on a device that is configured as a robotic system capable of moving autonomously and that has on board an ultraviolet light mechanism for surface disinfection combined with an air recirculation system, which allows two working modes: disinfection of surfaces by direct radiation and air by forced recirculation, combining all the advantages of current systems in one, with the added advantage of being able to be used safely even in environments where there are people and animals, since said UV light system can be hidden, affecting only the particles forced to pass through the interior of the device thanks to the air recirculation system.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de dispositivos para la desinfección de superficies y espacios, centrándose particularmente en el ámbito de los que utilizan luz UV, abarcando al mismo tiempo el ámbito de los sistemas de recirculación de aire. The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of devices for the disinfection of surfaces and spaces, focusing particularly on the field of those that use UV light, covering at the same time the field of air recirculation systems.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Según las pruebas existentes, la COVID-19 se transmite de una persona a otra por contacto directo o indirecto a través de objetos o superficies contaminadas donde el virus se deposita, pudiendo permanecer activo en dichas superficies desde vahas horas a incluso días. También se transmite si el virus queda suspendido en forma de aerosol y entra en contacto directo por las vías respiratorias de una persona. Las superficies y objetos pueden quedar contaminados por personas infectadas por medio de las secreciones bucales y nasales: la saliva, las secreciones respiratorias o las gotículas de secreciones que se expulsan por la boca o la nariz cuando una persona infectada tose, estornuda, habla o canta, por ejemplo. Las personas que están en contacto con dichas superficies contaminadas pueden contraer la COVID-19 a través de la boca, la nariz o los ojos por ejemplo al tocarlos con las manos. According to existing evidence, COVID-19 is transmitted from one person to another by direct or indirect contact through contaminated objects or surfaces where the virus is deposited, and can remain active on these surfaces from several hours to even days. It is also transmitted if the virus is suspended in aerosol form and comes into direct contact through a person's respiratory tract. Surfaces and objects can be contaminated by infected people through oral and nasal secretions: saliva, respiratory secretions, or droplets of secretions expelled from the mouth or nose when an infected person coughs, sneezes, speaks, or sings , for example. People who are in contact with such contaminated surfaces can contract COVID-19 through the mouth, nose or eyes, for example by touching them with their hands.
Por otra parte, también se ha demostrado que el riesgo de contagio del virus SARS-CoV-2 por vía aérea en forma de aerosol en el interior de los edificios es más elevado cuando existe poca ventilación. El hacinamiento, los espacios reducidos, cerrados o mal ventilados facilitan la trasmisión del coronavirus a través de partículas o micro gotas que permanecen suspendidas en el aire. Por ello, además de las medidas de higiene de superficies y suelos, así como el uso de mascarillas para reducir la emisión de aerosoles, es esencial implementar una serie de medidas en los sistemas de ventilación y climatización para garantizar una buena calidad del aire interior y evitar así los contagios. On the other hand, it has also been shown that the risk of contagion of the SARS-CoV-2 virus through the air in the form of an aerosol inside buildings is higher when there is little ventilation. Overcrowding, small, closed or poorly ventilated spaces facilitate the transmission of the coronavirus through particles or micro droplets that remain suspended in the air. For this reason, in addition to surface and floor hygiene measures, as well as the use of masks to reduce the emission of aerosols, it is essential to implement a series of measures in ventilation and air conditioning systems to guarantee good indoor air quality and thus avoid infection.
En los edificios sin sistema de ventilación mecánica se debe llevar a cabo una ventilación natural, abriendo puertas y ventanas el mayor tiempo posible. Con sistemas de climatización, se debe evitar la recirculación de aire, incrementando el aporte de aire fresco proveniente del exterior, todo lo que sea posible. In buildings without a mechanical ventilation system, natural ventilation must be carried out, opening doors and windows as long as possible. With air conditioning systems, air recirculation should be avoided, increasing the supply of fresh air from outside, as much as possible.
La luz ultravioleta se utiliza como método de desinfección desde hace años, pero en los últimos meses este sistema se ha puesto de completa actualidad por su eficacia en la desinfección contra la COVID-19. Ultraviolet light has been used as a disinfection method for years, but in recent months this system has become completely topical due to its effectiveness in disinfecting against COVID-19.
La luz ultravioleta (UV) es una luz invisible al ojo humano que se divide en tres tipos de menor a mayor intensidad: UVA, UVB y UVC. Esta última forma es la que se utiliza en los mecanismos de desinfección, ya que puede destruir el ADN de los microorganismos. Ultraviolet light (UV) is a light invisible to the human eye that is divided into three types from lower to higher intensity: UVA, UVB and UVC. This last form is the one used in disinfection mechanisms, since it can destroy the DNA of microorganisms.
Como consecuencia, cuando las bacterias, los virus y los protozoos se exponen a determinadas longitudes de onda de esta luz ultravioleta sus cadenas de ADN se ven afectadas impidiendo su reproducción quedando inactivos. Por ese motivo, desde hace años se aprovechan tales propiedades espermicidas para la desinfección del aire y diversas superficies. As a consequence, when bacteria, viruses and protozoa are exposed to certain wavelengths of this ultraviolet light, their DNA chains are affected, preventing their reproduction and becoming inactive. For this reason, such spermicidal properties have been used for years to disinfect the air and various surfaces.
Hay que tener en cuenta que este método con luz ultravioleta no añade componente químico alguno, un detalle especialmente importante al desinfectar el agua o los alimentos. Además, tampoco necesita ser procesado, por lo que destaca por poseer ciertas ventajas frente a otros sistemas de desinfección. Keep in mind that this method with ultraviolet light does not add a chemical component any, an especially important detail when disinfecting water or food. In addition, it does not need to be processed either, so it stands out for having certain advantages over other disinfection systems.
Teniendo en cuenta todas esas cualidades, la luz ultravioleta se usa para desinfectar superficies y objetos específicos a través de sistemas adecuados. También se usa para desactivar el virus suspendido en forma de aerosol, de manera muy efectiva si se integra en sistemas mecánicos de recirculación de aire. Entre los distintos ámbitos en los que se utiliza, hay que destacar las depuradoras de aguas residuales, los laboratorios, piscinas, acuarios y sistemas de aire acondicionado; la industria de alimentos y bebidas; la esterilización de instrumentos, estancias y superficies en el ámbito hospitalario; y para combatir el coronavirus, como, por ejemplo, con la desinfección de los medios de transporte público. Taking into account all these qualities, ultraviolet light is used to disinfect specific surfaces and objects through appropriate systems. It is also used to deactivate virus suspended in aerosol form, very effectively if integrated into mechanical air recirculation systems. Among the different areas in which it is used, we must highlight wastewater treatment plants, laboratories, swimming pools, aquariums and air conditioning systems; the food and beverage industry; the sterilization of instruments, rooms and surfaces in the hospital setting; and to combat the coronavirus, such as, for example, with the disinfection of public transport.
Las lámparas ultravioletas son efectivas contra la desinfección de determinadas áreas y superficies, aunque no se aconseja siempre su utilización. Por ejemplo, no deben usarse sobre la piel, pues la radiación puede producir irritaciones o graves efectos secundarios, y precisamente por ello no resultan adecuadas para tratar organismos vivos. Por ello, este método de desinfección debe ser realizado estableciendo las máximas medidas de seguridad y evitar la exposición de personas a la luz ultravioleta. Ultraviolet lamps are effective against the disinfection of certain areas and surfaces, although their use is not always recommended. For example, they should not be used on the skin, as radiation can cause irritation or serious side effects, and for this very reason they are not suitable for treating living organisms. Therefore, this disinfection method must be carried out by establishing the maximum security measures and avoiding the exposure of people to ultraviolet light.
Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, si bien existen en el mercado otros dispositivo para desinfección por luz UV así como dispositivo de ventilación, al menos por parte del solicitante, se desconoce la existencia de ningún dispositivo robotizado para desinfección por luz UV y ventilación, ni ninguna otra invención de aplicación similar, que presente unas características técnicas y estructurales ¡guales o semejantes a las que presenta el que aquí se reivindica. On the other hand, and as a reference to the current state of the art, it should be noted that, although there are other devices for disinfection by UV light on the market as well as a ventilation device, at least by the applicant, the existence of any robotic device for disinfection by UV light and ventilation, or any other invention of similar application, which has technical and structural characteristics equal to or similar to those of the one claimed here.
En dicho sentido, cabe mencionar que actualmente en el marcado se pueden encontrar muchos sistemas de desinfección basados en luz ultravioleta. In this sense, it is worth mentioning that many disinfection systems based on ultraviolet light can currently be found on the market.
Por un lado, se encuentran todos aquellos sistemas que basan su funcionamiento en encender un grupo de lámparas de luz ultravioleta, ya sea de manera estática o a bordo de algún tipo de vehículo que permita su desplazamiento. On the one hand, there are all those systems that base their operation on turning on a group of ultraviolet light lamps, either statically or on board some type of vehicle that allows them to move.
Esta solución está orientada a la desinfección de superficies por radiación directa de las lámparas. La eficacia de la desinfección será proporcional al tiempo de exposición y a la distancia a la superficie a desinfectar. También desinfecta el aire circundante a las lámparas, pero no como objetivo principal. This solution is aimed at disinfecting surfaces by direct radiation from the lamps. The effectiveness of the disinfection will be proportional to the exposure time and the distance to the surface to be disinfected. It also disinfects the air around the lamps, but not as its main purpose.
La desventaja de estos sistemas es que no pueden funcionar en presencia de organismos vivos. Suelen usarse en habitaciones cerradas donde se asegure que ninguna persona estará expuesta a la radiación y cumplimento estrictas normas de seguridad. The disadvantage of these systems is that they cannot function in the presence of living organisms. They are usually used in closed rooms where it is ensured that no person will be exposed to radiation and compliance with strict safety regulations.
Por otro lado, hay sistemas de desinfección por luz ultravioleta instalados dentro de torres de ventilación, aires acondicionados o dispositivos de recirculación de aire que están instalados de manera fija. On the other hand, there are ultraviolet light disinfection systems installed inside ventilation towers, air conditioners or air recirculation devices that are permanently installed.
Pues bien, el objetivo de la presente invención es proporcionar al mercado un dispositivo robotizado para asegurar, de manera efectiva, la desinfección de espacios mediante la combinación de la luz UV y la ventilación forzada a través de un dispositivo robotizado que puede actuar de modo autónomo y con la ventaja poder utilizarlo incluso en entornos donde haya presencia de personas o animales. Well, the objective of the present invention is to provide the market with a robotic device to effectively ensure the disinfection of spaces by combining UV light and forced ventilation through a robotic device that can act autonomously and with the advantage of being able to use it even in environments where there is the presence of people or animals.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
El dispositivo robotizado para desinfección por luz UV y ventilación que la invención propone permite alcanzar satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo hacen posible y que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción. The robotic device for disinfection by UV light and ventilation that the invention proposes makes it possible to satisfactorily achieve the aforementioned objectives, the characterizing details that make it possible and that conveniently distinguish it being collected in the final claims that accompany this description.
En concreto, lo que la invención propone, como se ha apuntado anteriormente, es un dispositivo que se configura como un sistema robotizado capaz de desplazarse de manera autónoma y que lleva a bordo un mecanismo de luces ultravioletas para desinfección de superficies combinado con un sistema de recirculación de aire, el cual permite dos modos de trabajo: desinfección de superficies por radiación directa y de aire por recirculación forzada, aunando todas las ventajas de los sistemas actuales en uno sólo, y con la ventaja añadida de poder utilizarse de manera totalmente segura incluso en entornos donde haya personas y animales, ya que el sistema de luces UV puede quedar oculto y actuar únicamente sobre las partículas forzadas a pasar por el dispositivo gracias al sistema de recirculación de aire. Specifically, what the invention proposes, as noted above, is a device that is configured as a robotic system capable of moving autonomously and that has on board an ultraviolet light mechanism for surface disinfection combined with a system of air recirculation, which allows two working modes: disinfection of surfaces by direct radiation and air by forced recirculation, combining all the advantages of current systems in one, and with the added advantage of being able to be used completely safely even in environments where there are people and animals, since the UV light system can be hidden and act only on the particles forced to pass through the device thanks to the air recirculation system.
Para ello, y de manera más concreta, el dispositivo comprende, esencialmente, los siguientes elementos: - una base móvil, con medios para procurar el desplazamiento autónomo del dispositivo, sin perjuicio de que también pueda ser manual, por las zonas a desinfectar; y For this, and more specifically, the device essentially comprises the following elements: - a mobile base, with means to ensure the autonomous movement of the device, without prejudice to the fact that it can also be manual, through the areas to be disinfected; Y
- una torre superior con un conjunto de lámparas emisoras de luz UV, concretamente UVC, y un ventilador capaz de mover un caudal de aire hacia el interior hueco dicha torre quedando bajo los efectos de la luz UV de, al menos, algunas de las lámparas. - an upper tower with a set of UV light-emitting lamps, specifically UVC, and a fan capable of moving a flow of air into the hollow interior of said tower, remaining under the effects of UV light from, at least, some of the lamps .
Preferentemente, la torre tiene una configuración circular o cuadrangular y comprende algunas lámparas de luz UV incorporadas de modo fijo en posición vertical y otras incorporadas de modo que permiten un movimiento de abatimiento de las mismas con distinta inclinación y en hasta 90° sobre la vertical para situarse en posición perpendicular a la envolvente exterior de la torre circular. Preferably, the tower has a circular or quadrangular configuration and includes some UV light lamps incorporated in a fixed manner in a vertical position and others incorporated in such a way that they allow their lowering movement with different inclinations and up to 90° from the vertical to be placed perpendicular to the outer envelope of the circular tower.
En una forma de realización, en el interior hueco de la torre hay instalado uno o más filtros HEPA (del inglés "High Efficiency Particle Arrestinc/', o "recogedor de partículas de alta eficiencia") de limpieza de aire, capaces de retener partículas del tamaño del virus COVID- 19. In one embodiment, one or more HEPA (High Efficiency Particle Arrestinc/', or "high efficiency particle collector") air cleaning filters are installed in the hollow interior of the tower, capable of retaining particles the size of the COVID-19 virus.
Preferentemente, dichos filtros tienen forma cilindrica y también son huecos en su interior, con un espesor de pared tal que permite instalar en el centro de los mismos una o más lámparas de luz UV en formato alargado, tipo fluorescente, de longitud similar a la altura de la torre. Preferably, said filters have a cylindrical shape and are also hollow inside, with a wall thickness such that it is possible to install one or more UV light lamps in their center in an elongated format, fluorescent type, with a length similar to the height of the tower.
En otra forma de realización, el interior hueco de la torre no dispone de filtros y solo incorpora lámparas UV orientadas hacia el interior. In another embodiment, the hollow interior of the tower has no filters and only incorporates inward-facing UV lamps.
En cualquier caso, preferentemente, el ventilador, que mueve de manera forzada un caudal de aire hacia el interior hueco de la torre, va incorporado en la parte superior de la misma. Dado que la parte inferior de la torre está tapada, el aire sólo puede salir del interior de la torre pasando a través de las lámparas de luz ultravioleta que de una sola pasada, gracias a la dosis de radiación aplicada, garantizan una completa desinfección del aire. In any case, preferably, the fan, which forcefully moves a flow of air towards the hollow interior of the tower, is incorporated in the upper part of the tower. Since the lower part of the tower is covered, the air can only leave the interior of the tower by passing through the ultraviolet light lamps which, thanks to the dose of radiation applied, guarantee a complete disinfection of the air in a single pass. .
Las luces ultravioletas instaladas en el interior y en el exterior de la torre desinfectan el aire que mueve el ventilador a su paso y, en su caso, también la cara interior del cilindro de filtros HEPA. The ultraviolet lights installed inside and outside the tower disinfect the air moved by the fan as it passes and, where appropriate, also the inside face of the HEPA filter cylinder.
Además, es importante destacar que, en una forma de realización preferida de la invención las lámparas ultravioleta de la parte exterior de la torre pueden ser protegidas y tapadas mediante un sistema de cubiertas móviles previsto al efecto en el dispositivo, las cuales evitan, por un lado, la rotura accidental de las lámparas por golpes y, por otro lado, la radiación exterior de luz UV, y además, a su vez, favorecen la canalización del aire en el interior de la torre para una maximización de la desinfección a través de las lámparas UV. Furthermore, it is important to note that, in a preferred embodiment of the invention the ultraviolet lamps on the outside of the tower can be protected and covered by means of a system of mobile covers provided for this purpose in the device, which prevent, on the one hand, accidental breakage of the lamps due to knocks and, on the other hand, external radiation of UV light, and also, in turn, favor the channeling of air inside the tower to maximize disinfection through UV lamps.
Con todo ello, el funcionamiento del dispositivo será, preferentemente, el siguiente: With all this, the operation of the device will be, preferably, the following:
Para la desinfección de superficies por radiación directa de luz UV, el dispositivo robotizado, gracias a la base móvil, se desplaza con las cubiertas abiertas permitiendo a las luces de la torre irradiar todas las superficies a la vista en 360°. Además, las lámparas abatibles, cuando se despliegan en su posición horizontal, aumentan la eficacia de desinfección al irradiar de manera perpendicular superficies horizontales como mesas o camas. For the disinfection of surfaces by direct radiation of UV light, the robotic device, thanks to the mobile base, moves with the covers open allowing the lights of the tower to irradiate all the surfaces in sight in 360°. In addition, folding lamps, when unfolded in their horizontal position, increase disinfection efficiency by irradiating horizontal surfaces such as tables or beds perpendicularly.
Lógicamente, en este modo de funcionamiento, no está permitida la presencia de personas por los riesgos que se tiene contra la salud. Logically, in this operating mode, the presence of people is not allowed due to the risks to health.
Además, y aquí la gran ventaja del dispositivo de la invención, este al mismo tiempo también puede desinfectar el virus en su formato aerosol haciendo que el ventilador de la parte superior de la torre haga circular de manera forzada aire por el interior de la misma. Con la dosis suministrada, la desinfección es completa, ya que quedan tratadas todas las superficies a su alcance mientras navega y también desinfecta el aire en grandes volúmenes, permitiendo igualar los tiempos de desinfección de superficies y la totalidad del aire en el mismo intervalo de tiempo. In addition, and here is the great advantage of the device of the invention, it can also disinfect the virus in its aerosol format at the same time, causing the fan at the top of the tower to forcefully circulate air inside it. With the supplied dose, the disinfection is complete, since all the surfaces within its reach are treated while navigating and it also disinfects the air in large volumes, allowing the disinfection times of surfaces and the entire air to be equalized in the same time interval .
Otra gran ventaja es que, asimismo, en otro modo de funcionamiento, el dispositivo se puede dejar estático, con las cubiertas cerradas para que no irradie luz UV al exterior de la torre, y con el sistema de ventilación forzada en funcionamiento. De esta manera se puede desinfectar el ambiente de una habitación o espacio cerrado, con mala o nula ventilación, y con presencia de personas y/o animales. Así se asegura protección adicional de las personas frente a la COVID-19 cuando no sea posible mantener un espacio ventilado. Another great advantage is that, likewise, in another operating mode, the device can be left static, with the covers closed so that UV light does not radiate outside the tower, and with the forced ventilation system in operation. In this way you can disinfect the environment of a room or closed space, with poor or no ventilation, and with the presence of people and/or animals. This ensures additional protection of people against COVID-19 when it is not possible to maintain a ventilated space.
Un ejemplo de aplicación sería una reunión de personas dentro de una sala sin ventilación que tenga un aire acondicionado recirculando el aire. En este caso, el dispositivo robotizado estaría funcionando en modo compatible con la presencia de personas, con las cubiertas de la torre cerradas para evitar irradiar luz ultravioleta al exterior y con el sistema de ventilación forzada activado para desinfectar el aire de la sala a través de la luz ultravioleta que incide sobre el aire que pasa a su través y, opcionalmente, sobre los filtros. An example of an application would be a gathering of people inside an unventilated room that has an air conditioner recirculating the air. In this case, the robotic device would be working in a mode compatible with the presence of people, with the tower covers closed to avoid radiating ultraviolet light to the outside, and with the ventilation system. activated to disinfect the air in the room through ultraviolet light that falls on the air that passes through it and, optionally, on the filters.
Una vez la reunión acaba y las personas abandonan la sala, se podrá activar el funcionamiento del dispositivo para la limpieza de superficies con las luces ultravioletas activadas e irradiando al exterior, extrayendo las cubiertas, permitiendo la navegación autónoma del dispositivo por toda la sala que garantice una desinfección de todas las zonas y superficies comprometidas sin presencia de personas. Once the meeting is over and people leave the room, the operation of the device can be activated to clean surfaces with the ultraviolet lights activated and radiating to the outside, removing the covers, allowing the autonomous navigation of the device throughout the room that guarantees a disinfection of all compromised areas and surfaces without the presence of people.
Cabe señalar, además, que el dispositivo robotizado objeto de la invención contempla diversas opciones adicionales de realización que amplían sus prestaciones permitiendo diferentes modos de funcionamiento enfocados a entornos y clientes con distintas necesidades. It should also be noted that the robotic device that is the object of the invention contemplates various additional implementation options that extend its performance, allowing different operating modes focused on environments and clients with different needs.
Así, en una forma de realización, el dispositivo cuenta con unos soportes para las lámparas abatióles que son regulables en altura y abatimiento de forma programadle con un ángulo de de entre 0 a 90°, pudiendo disponer de 1 o 2 de dichos soportes o de ninguno, en función de los entornos o necesidades del área o zona a desinfectar, ya que los mismos permiten optimizar la desinfección de superficies cuando están en diferentes planos, por ejemplo mesas, sillas, camas, que requieren de un tratamiento diferencial, y que el grado de desinfección de las lámparas de luz UV va directamente relacionado con la distancia de aplicación de la luz, siendo esta posibilidad de ajuste de los citados soportes en un importante factor diferencial frente a otros sistemas conocidos. Thus, in one embodiment, the device has supports for the abatioles lamps that are adjustable in height and tilt in a programmable way with an angle of between 0 to 90 °, being able to have 1 or 2 of said supports or none, depending on the environments or needs of the area or zone to be disinfected, since they allow optimizing the disinfection of surfaces when they are in different planes, for example tables, chairs, beds, which require differential treatment, and that the The degree of disinfection of the UV light lamps is directly related to the distance from which the light is applied, this possibility of adjusting the aforementioned supports being an important differentiating factor compared to other known systems.
Asimismo, en una forma de realización, el dispositivo comprende una pantalla informativa. Dada la posibilidad que permite el dispositivo de trabajar en modo desinfección de aire en entornos en los cuales las personas pueden estar alrededor del equipo sin ningún riesgo para su salud, y gracias a los sistemas de protección y medidas de seguridad de que dispone, la invención permite contar con una pantalla informativa aplicable para ser utilizada como un punto de atención y publicidad en entornos con mucha concurrencia de personas, por ejemplo centros comerciales. Also, in one embodiment, the device comprises an information screen. Given the possibility that the device allows to work in air disinfection mode in environments in which people can be around the equipment without any risk to their health, and thanks to the protection systems and security measures available, the invention It allows to have an applicable information screen to be used as a point of attention and advertising in environments with a large number of people, for example shopping centers.
Por otra parte, para el control y manejo del dispositivo robotizado de desinfección, de preferencia, este dispone de una pantalla de control con carácter extraíble que permite controlar a distancia el robot en la totalidad de sus funciones, de esta forma el operador podrá interactuar de forma segura para iniciar los procesos de desinfección en aquellos modos en los cuales las lámparas exteriores deban de funcionar, lo cual no permitiría realizar el arranque del robot en su proximidad. On the other hand, for the control and management of the robotic disinfection device, preferably, it has a removable control screen that allows remote control of the robot in all its functions, in this way the operator can interact safe way to start the disinfection processes in those modes in which which the external lamps must work, which would not allow the robot to start up in its vicinity.
Además, en una forma de realización preferida, la torre superior es un elemento extraíble de la base e intercambiable, de tal modo que permite poder intercambiar la torre de desinfección en su totalidad, sustituyendo la misma por otros elementos que como un robot colaborativo, estanterías, etc., que permiten aumentar el rango de aplicaciones del dispositivo a otras aplicaciones complementarias, a demanda del cliente, aumentando la utilidad y el retorno de la inversión. In addition, in a preferred embodiment, the upper tower is an element that can be removed from the base and is interchangeable, in such a way that it allows the disinfection tower to be exchanged in its entirety, replacing it with other elements such as a collaborative robot, shelves , etc., that allow to increase the range of applications of the device to other complementary applications, at the request of the client, increasing the usefulness and the return on the investment.
Finalmente, aunque el dispositivo de la invención cuenta con una batería que ya le otorga una importante autonomía de trabajo, en una forma de realización preferida, dicha batería está incorporada en un alojamiento específico que permite su extracción fácil y para permitir el intercambio de baterías, alargando de forma prácticamente indefinida la operativa del dispositivo. Finally, although the device of the invention has a battery that already gives it a significant working autonomy, in a preferred embodiment, said battery is incorporated in a specific housing that allows its easy removal and to allow the exchange of batteries, extending practically indefinitely the operation of the device.
