El objeto de al invencion es acortar el tiempo de secado de la pintura aplicada en vehiculos como los anteriormente comentados.The object of the invention is to shorten the drying time of the paint applied in vehicles such as those mentioned above.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
Como es sabido, el secado de la pintura aplicable en el sector de la automocion o incluso en otros, se realiza mediante aire a temperatura ambiente, con pistolas de aire a presion que impulsan el aire a una temperatura que oscila entre los 01aC y los 17° C(dependiendo de las condiciones climaticas de la zona en la que se realice la medicion),es decir a una temperatura generalmente inferior que la temperatura ambiente, lo que lleva consigo que el secado sea lento y por lo tanto requiere un notable tiempo para conseguir el secado total de la pintura.As it is known, the drying of the paint applicable in the automotive sector or even in others, is carried out by means of air at room temperature, with pressurized air guns that propel the air at a temperature that oscillates between 01aC and 17 ° C (depending on the climatic conditions of the area where the measurement is performed), that is to say at a temperature generally lower than the ambient temperature, which leads to slow drying and therefore requires a considerable time to get the total drying of the paint.
DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION

El dispositivo se basa en un aparato a modo de pistola con una entrada de aire atmosferica y una toma para conexion de un compresor de aire, e impulsion del correspondiente flujo de aire a presion, incluyendo en el interior del canon del propio aparato a modo de pistola, una resistencia electrica para el calentamiento del aire entrante, saliendo al exterior por el extremo opuesto, para su aplicacion en el repintado y reparation de la pintura del veticulo, estando conectado el aparato a un compresor con un adaptador para toma de aire, todo ello de manera tal que el aparato incluye un pulsador de accionamiento del aire caliente, mejor dicho de accionamiento de la resistencia electrica para llevar a cabo el calentamiento del aire que accede al interior del aparato, ya sea mediante la entrada de aire del compresor o el aire que aspira el propio aparato al hacer el efecto venturi por su parte posterior). Este interruptor on/off permite utilizar la maquina tanto con aire caliente (cuando esta en position on) como con aire frio o a temperatura ambiente (cuando esta en posicion off), lo que hace que esta maquina funcione como si de dos maquinas se tratara.The device is based on a gun-like device with an atmospheric air inlet and an outlet for connecting an air compressor, and driving the corresponding flow of pressurized air, including inside the canon of the device itself as a gun, an electric resistance for heating the incoming air, going outside at the opposite end, for application in the repainting and reparation of the paint of the vehicle, the device being connected to a compressor with an adapter for air intake, all this in such a way that the apparatus includes a hot air actuation button, rather electric resistance actuation to carry out the heating of the air that accesses the interior of the apparatus, either by means of the compressor air inlet or the air aspirated by the device itself when doing the venturi effect on the back). This on / off switch allows the machine to be used both with hot air (when it is in position on) and with cold air or at room temperature (when it is in position off), which makes this machine work as if it were two machines.
De esta forma se consigue aplicar aire caliente que puede alcanzar hasta los 40° C o incluso mas, acortando con ello el tiempo de secado aproximadamente a la mitad de lo que se requiere con el secado mediante aire a temperatura ambiente.In this way it is possible to apply hot air that can reach up to 40 ° C or even more, thereby shortening the drying time by approximately half of what is required with air drying at room temperature.
La pintura base agua realiza su secado por evaporation, lo que se consigue como se deda con anterioridad de forma mas eficaz y rapida en virtud de la aplicacion de aire caliente sobre la dicha pintura.The water-based paint dries by evaporation, which is achieved as previously given more efficiently and quickly by virtue of the application of hot air on said paint.
A partir de esta estructuracion, se obtienen las siguientes ventajas:From this structure, the following advantages are obtained:
1. Ahorro de electricidad al disminuir el tiempo que tenemos conectada la cabina de pintura para calentar el ambiente antes de empezar a pintar (la temperatura de la cabina durante la noche en reposo disminuye de forma que el pigmento si no esta a una temperatura adecuada no se adhiere a las piezas del vehiculo como debiera) y mientras aplicamos las capas de pigmento.1. Electricity savings by decreasing the time that we have connected the paint booth to heat the environment before starting to paint (the temperature of the booth at night at rest decreases so that the pigment if it is not at an adequate temperature does not adheres to the vehicle parts as it should) and while applying the pigment layers.
2. Ahorro de combustible ya que no es necesario conectar el motor de la cabina (motor de combustion que funciona con gasoleo) para calentar el lugar de aplicacion en2. Fuel saving as it is not necessary to connect the cabin engine (combustion engine that runs on diesel) to heat the application site in

REALIZACION PREFERENTE DE LA INVENCIONPREFERRED EMBODIMENT OF THE INVENTION
Como se puede ver en la figura referida, el dispositivo (1) de la invencion esta formado por un cuerpo a modo de pistola, con un cable (2) de conexion a corriente electrica, presentado el cuerpo (1) del dispositivo, una parte cilmdrica (4) con una serie de hendiduras longitudinales que permiten un enfriamiento mas rapido del cilindro e impiden tanto el sobrecalentamiento de la maquina como una posible quemadura al contacto con el mismo durante su uso, en cuyo interior se ha previsto una resistencia electrica de calentamiento, contando dicho cuerpo en uno de sus extremos con una pantalla (6) para la entrada de aire del exterior, a modo de elemento de refrigeration, y una boca de salida (7) del aire caliente en la cual son acoplables selectivamente una serie de boquillas modulares intercambiables (3-3’-3’’-3’’’) con las cuales conseguimos diferentes efectos dependiendo de la canalization que hagamos del aire, todo ello en combinacion con un compresor que aplica aire a traves de un adaptador (8) con un regulador de presion (9) segun se ve en la figura, de manera que mediante la presion de aire proveniente del compresor y la entrada de aire o pantalla (6) se consigue un efecto Venturi a la salida (7) de la pistola.As can be seen in the aforementioned figure, the device (1) of the invention is formed by a gun-like body, with an electric current connection cable (2), the body (1) of the device, a part being presented cylindrical (4) with a series of longitudinal grooves that allow faster cooling of the cylinder and prevent both overheating of the machine and a possible burn on contact with it during use, in which an electric heating resistance is provided , said body counting at one of its ends with a screen (6) for the entry of outside air, as a cooling element, and an outlet (7) of the hot air in which a series of selectively attachable interchangeable modular nozzles (3-3'-3 '' - 3 '' ') with which we achieve different effects depending on the channeling we make of the air, all in combination with a compressor that applies air through of an adapter (8) with a pressure regulator (9) as seen in the figure, so that by means of the air pressure coming from the compressor and the air inlet or screen (6) a Venturi effect is achieved at the outlet (7) of the gun.
De esta forma, la entrada de aire (6) en combination con el compresor conectado a traves del adaptador (8) y toma de aire, puede ser calentada mediante la activacion de la resistencia electrica saliendo el aire por las salida (7), caliente para su aplicacion en el secado de pintura de vehiculos y otros.In this way, the air inlet (6) in combination with the compressor connected through the adapter (8) and air intake, can be heated by activating the electric resistor leaving the air through the outlet (7), hot for application in the drying of vehicle and other paint.
La activacion de la resistencia electrica interna debe realizarse mediante un pulsador manual (10), situado en la parte trasera de la maquina, siempre que haya presion de aire, de manera que si no se abre el regulador de presion (9) la resistencia no se activara, contando para ello con un sensor de presion asociado al circuito de alimentation de la resistencia.The activation of the internal electrical resistance must be carried out by means of a manual button (10), located at the rear of the machine, provided there is air pressure, so that if the pressure regulator (9) is not opened, the resistance does not open it will be activated, counting for it with a pressure sensor associated to the resistance supply circuit.
