Esta capa impide que el conductor tenga una visión adecuada, lo cual hace imprescindible que éste tenga que retirarla.In places where it is very cold or very humid, it is common for the exterior surface of the windshields of cars to have a layer of ice, frost, fog or the like. This layer prevents the driver from having adequate vision, which makes it imperative that he has to remove it.
Actualmente, para retirar esta capa de forma rápida es necesario que el conductor utilice una herramienta adecuada o extienda manualmente un líquido adecuado sobre la superficie externa del parabrisas. Un líquido adecuado puede ser, por ejemplo, agua caliente, anticongelante o la mezcla de ambos.Currently, to remove this layer quickly it is necessary for the driver to use a suitable tool or manually spread a suitable liquid on the outer surface of the windshield. A suitable liquid may be, for example, hot water, antifreeze or the mixture of both.
La utilización de una herramienta para retirar la capa tiene el inconveniente de que requiere mucho tiempo para retirarla en su totalidad, aparte de la incomodidad de tener que retirarla manualmente.The use of a tool to remove the layer has the disadvantage that it requires a lot of time to remove it in its entirety, apart from the inconvenience of having to remove it manually.
Si se retira mediante agua caliente, el inconve- niente es que el agua hace que se descongele el hielo, pero si no se retira inmediatamente, y dependiendo de la temperatura exterior, ésta se vuelva a congelar.If removed by hot water, the inconve- The point is that the water causes the ice to defrost, but if it is not removed immediately, and depending on the outside temperature, it will freeze again.
Por otra parte, la utilización de anticongelante tiene los inconvenientes de su alto costo y la incomodidad de tener que extenderlo sobre el parabrisas manualmente .On the other hand, the use of antifreeze has the disadvantages of its high cost and the inconvenience of having to extend it on the windshield manually.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERIDADESCRIPTION OF A PREFERRED EMBODIMENT
Tal como se puede apreciar en la única figura, el sistema de la invención comprende un recinto 2 integrado en el depósito 1 de fluido para limpiar el parabrisas. En el interior del recinto 2 esta dispuesta una válvula de turbina 3, una cámara 4 provista de una resistencia helicoidal 5 en su interior, dos electroválvulas 7 y medios de control 6 de todos los componentes del sistema de la invención. En el interior de dicha cámara 4 también está dispuesta una sonda NTC 8 para detectar la temperatura del fluido en la cámara 4.As can be seen in the single figure, the system of the invention comprises an enclosure 2 integrated in the fluid reservoir 1 for cleaning the windshield. Inside the enclosure 2 there is a turbine valve 3, a chamber 4 provided with a helical resistor 5 inside, two solenoid valves 7 and control means 6 of all the components of the system of the invention. Inside said chamber 4 an NTC probe 8 is also arranged to detect the temperature of the fluid in chamber 4.
La resistencia helicoidal 5 comprende en uno de sus extremos una soldadura de baja temperatura por motivos de seguridad. De esta forma, cuando se alcanza una temperatura superior a un valor predeterminado, habi- tualmente entre 200 y 300°C, dicha soldadura se rompe, desactivando la resistencia.The helical resistance 5 comprises at one of its ends a low temperature welding for safety reasons. In this way, when a temperature higher than a predetermined value is reached, usually between 200 and 300 ° C, said welding is broken, deactivating the resistance.
La sonda NTC está en contacto directo con el fluido en el interior de la cámara 4, estando provista dicha sonda 8 de una funda de un material conductor, tal como latón o aluminio, en contacto con el fluido.The NTC probe is in direct contact with the fluid inside the chamber 4, said probe 8 being provided with a sheath of a conductive material, such as brass or aluminum, in contact with the fluid.
La cámara 4 tiene preferentemente una forma cilindrica, con un diámetro comprendido entre 20 y 30 mm, teniendo un volumen de 100 cm3 aproximadamente. Este diámetro está diseñado para impedir que el agua a temperatura ambiente que entra en la cámara no se mezcle con el agua caliente que sale de la misma, consiguiendo de esta forma un flujo continuo.The chamber 4 preferably has a cylindrical shape, with a diameter between 20 and 30 mm, having a volume of approximately 100 cm 3 . This diameter is designed to prevent water from Ambient temperature entering the chamber does not mix with the hot water that comes out of the chamber, thus achieving a continuous flow.
Las electroválvulas 7 dispuestas a la salida de la cámara 4 están abiertas en posición de reposo, y cada una de ellas está conectada a un surtidor. La salida del fluido sobre la superficie externa del parabrisas se realiza de forma abierta, de forma que abarque la superficie suficiente para permitir la visión. Preferentemente, estos surtidores estarán colocados en la parte inferior del parabrisas.The solenoid valves 7 arranged at the outlet of the chamber 4 are open in the rest position, and each of them is connected to a dispenser. The exit of the fluid on the external surface of the windshield is carried out openly, so that it covers the surface sufficient to allow vision. Preferably, these jets will be placed at the bottom of the windshield.
Para accionar el sistema de la invención está provisto un interruptor colocado en el tablero de mandos del vehículo. Habitualmente, este interruptor dispondrá de una luz para que el ocupante del vehículo sepa cuando está en funcionamiento el sistema de la invención.To operate the system of the invention, a switch is provided placed on the dashboard of the vehicle. Usually, this switch will have a light so that the occupant of the vehicle knows when the system of the invention is in operation.
El sistema de la invención solamente se activará cuando la tensión nominal de la instalación sea superior a 14 voltios.The system of the invention will only be activated when the nominal voltage of the installation is greater than 14 volts.
De esta forma, cuando el ocupante del vehículo desea accionar el sistema de la invención, debe pulsar el interruptor correspondiente. En este momento, se activará la bomba 3 introduciendo el fluido en la cámara 4 y la resistencia 5, que lo calentará. Un segundo más tarde se accionarán las electroválvulas 7, ya que en caso contrario, la cámara 4 podría estar parcialmente vacía, y no se calentaría la cantidad de fluido adecuada. La presión de la bomba de turbina 3 es aproximadamente de 3Kg/cm2, que es suficiente para mantener la cámara 4 siempre llena cuando se produce el calentamiento.In this way, when the vehicle occupant wishes to operate the system of the invention, he must press the corresponding switch. At this time, the pump 3 will be activated by introducing the fluid into the chamber 4 and the resistance 5, which will heat it. A second later the solenoid valves 7 will be activated, since otherwise, the chamber 4 could be partially empty, and the adequate amount of fluid would not be heated. The pressure of the turbine pump 3 is approximately 3Kg / cm 2 , which is sufficient to keep chamber 4 always full when heating occurs.
Cuando la sonda 8 detecta una temperatura de 90 °C del fluido, los medios de control 6 darán la señal para que una de las electroválvulas 7 se abra, impulsando el fluido sobre la superficie externa del parabrisas. La electroválvula que se abre en primer lugar es la que está comunicada con el surtidor correspondiente al lado del conductor.When the probe 8 detects a temperature of 90 ° C of the fluid, the control means 6 will give the signal for one of the solenoid valves 7 to open, propelling the fluid on the external surface of the windshield. The solenoid valve that opens first is the one that is connected to the corresponding supplier next to the driver.
Los medios de control 3 hacen que esta electrovál- vula 7 esté abierta durante 12 segundos, pasados los cuales se cierra. Cuando la sonda 8 detecta otra vez una temperatura de 90 °C en el fluido, los medios de control 3 abren la otra electroválvula 7 durante otros 12 segundos. Una vez pasados estos 12 segundos se desconec- ta todo el sistema. Está previsto que el consumo de fluido sea de 300 a 400 cm3 cada vez que se acciona el sistema.The control means 3 make this solenoid valve 7 open for 12 seconds, after which it closes. When the probe 8 again detects a temperature of 90 ° C in the fluid, the control means 3 open the other solenoid valve 7 for another 12 seconds. Once these 12 seconds have elapsed, the entire system is disconnected. The fluid consumption is expected to be 300 to 400 cm 3 each time the system is operated.
Preferentemente, el fluido utilizado será agua mezclada con anticongelante, aunque podría emplearse únicamente agua.Preferably, the fluid used will be water mixed with antifreeze, although only water could be used.
