D E S C R I P C I Ó N SISTEMA PARA EXTENDER UN FLUIDO SOBRE LA SUPERFICIE EXTERNA DEL PARABRISAS DE UN VEHÍCULOD E S C R I P C I O N SYSTEM TO EXTEND A FLUID ON THE EXTERNAL SURFACE OF THE WINDSHIELD OF A VEHICLE
La presente invención se refiere a un sistema para extender un fluido sobre la superficie externa del parabrisas de un vehículo para fundir el hielo que pueda haber sobre el mismo o bien desempañarlo ex- teriormente .The present invention relates to a system for spreading a fluid on the external surface of the windshield of a vehicle to melt the ice that may be on it or to defog it externally.
ANTECEDENTES OE T.A TNVENCTÓNBACKGROUND OE T. A TNVENCTÓN
En lugares donde hace mucho frío o que son muy húmedos es habitual que la superficie exterior de los parabrisas de los automóviles se cubra de una capa de hielo, escarcha, vaho o similares. 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 be covered with 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 dicha capa de hielo de forma rápida es necesario que el conductor utilice una herramienta apropiada o extienda manualmente un líquido adecuado sobre la superficie externa del parabrisas. Este líquido adecuado puede ser, por ejemplo, agua caliente o anticongelante puro.Currently, to remove said ice sheet quickly it is necessary for the driver to use an appropriate tool or manually spread a suitable liquid on the outer surface of the windshield. This suitable liquid may be, for example, hot water or pure antifreeze.
La utilización de una herramienta para arrancar la capa de hielo tiene el inconveniente de que re- quiere bastante tiempo lograr desprenderla en su totalidad, aparte de la incomodidad de tener que operar manualmente . - 2 -The use of a tool to tear off the ice sheet has the disadvantage that it takes quite some time to be able to detach it in its entirety, apart from the inconvenience of having to operate manually. - two -
Si se retira el hielo mediante agua caliente, el inconveniente es que el conductor no siempre puede disponer de suficiente cantidad de ésta para lograr retirar completamente el hielo. Además, si a causa de no disponer de agua caliente de manera inmediata no se retira rápidamente dicho hielo, y dependiendo de la temperatura exterior, es posible que, a su vez, el agua añadida se enfríe hasta congelarse.If the ice is removed by hot water, the drawback is that the driver may not always have enough of it to completely remove the ice. In addition, if the ice is not immediately removed due to the lack of hot water, and depending on the outside temperature, it is possible that, in turn, the added water will cool until it freezes.
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 PREEERTDADESCRIPTION OF A PERFORMANCE
En las figuras 1 y 2 se pueden observar esquemáticamente los componentes que forman el sistema de la invención. El fluido 1, habitualmente agua calentada a una temperatura de unos 50°, es extendido sobre el parabrisas 2 de un automóvil mediante dos pares de toberas 3. En la realización representada en la figura 1, el fluido 1 es agua del depósito 8 de líquido lim- piaparabrisas . Como se puede apreciar en la figura 2, en el interior de un recinto cerrado 9 está dispuesta una bomba 7, que impulsa el agua desde el depósito 8 al interior del recinto 9.Figures 1 and 2 show schematically the components that make up the system of the invention. The fluid 1, usually water heated to a temperature of about 50 °, is spread over the windshield 2 of a car by two pairs of nozzles 3. In the embodiment shown in Figure 1, the fluid 1 is water from the liquid reservoir 8 wiper washer . As can be seen in Figure 2, inside a closed enclosure 9 a pump 7 is arranged, which drives the water from the reservoir 8 into the enclosure 9.
A continuación el agua pasa alrededor de una resistencia 4, donde se realiza su calentamiento. Para permitir este paso, alrededor de la resistencia 4 está dispuesto un conducto helicoidal (no representado) a modo de serpentín, estando formado dicho conducto helicoidal a partir de una lámina dispuesta alrededor de la resistencia 4 a modo de paso de rosca. La resistencia 4 tiene forma cilindrica con una funda exterior de cobre, está situada en el interior de un cilindro de 100 milímetros de largo y 16 milímetros de diámetro, y está aislada herméticamente de los restantes componentes .The water then passes around a resistor 4, where its heating is carried out. To allow this passage, around the resistor 4 a helical conduit (not shown) is arranged as a coil, said conduit being formed helical from a sheet arranged around the resistance 4 as a thread. The resistor 4 has a cylindrical shape with an outer copper sheath, is located inside a cylinder 100 millimeters long and 16 millimeters in diameter, and is hermetically isolated from the remaining components.
Después de pasar alrededor de la resistencia 4, el agua calentada pasa a una válvula 5, la cual comprende dos conductos de salida 13. Cada uno de estos conductos 13 se dirige hasta un par de toberas 3 conectadas en paralelo. La válvula 5 cierra y abre alternativamente la alimentación a los conductos 13, de manera que el agua calentada sale alternativamente por cada par de toberas 3. Los conductos de salida 13 citados son preferentemente perfiles tubulares de caucho sintético con un diámetro interior de 2 milímetros .After passing around the resistor 4, the heated water passes to a valve 5, which comprises two outlet ducts 13. Each of these ducts 13 is directed to a pair of nozzles 3 connected in parallel. The valve 5 alternately closes and opens the feed to the ducts 13, so that the heated water comes out alternately through each pair of nozzles 3. The outlet ducts 13 mentioned are preferably tubular profiles of synthetic rubber with an inner diameter of 2 millimeters.
En el interior del recinto 9 citado también está dispuesto un dispositivo de control 6, que actúa sobre los otros componentes dispuestos en el interior de dicho recinto 9, gobernando su funcionamiento de forma automática.Inside the enclosure 9 mentioned there is also a control device 6, which acts on the other components arranged inside said enclosure 9, governing its operation automatically.
El dispositivo de control 6 está conectado a la batería 10 del vehículo, recibiendo la señal de funcionamiento automático a través de un momentáneo encendido de la luz de carretera 12 en el mismo instante de arrancar el motor. El circuito eléctrico del sistema de la invención está conectado a masa 11. - 8 -The control device 6 is connected to the battery 10 of the vehicle, receiving the automatic operation signal through a momentary illumination of the high beam 12 at the same time the engine is started. The electrical circuit of the system of the invention is connected to ground 11. - 8 -
Como se puede apreciar en la figura 1, el agua calentada 1 sale por la parte superior del parabrisasAs can be seen in Figure 1, the heated water 1 exits from the top of the windshield
2 de manera abierta o sea en forma de abanico, de forma que cubre la superficie de modo suficiente para garantizar una correcta visión al conductor.2 openly or in the form of a fan, so that it covers the surface sufficiently to ensure correct vision to the driver.
En la figura 4 se puede apreciar como los pares de toberas 3 están fijados al parabrisas 2. Sobre el parabrisas 2 se fija una placa 15 provista de una lámina adhesiva 16, comprendiendo dicha placa 15 un alojamiento 14 solidario a la misma. En el interior de dicho alojamiento 14 va acoplado un manguito 17 provisto en los pares de toberas 3. Cada par de toberas 3 comprende dos manguitos 17 para hacer más estable el acoplamiento. Los manguitos 17 están dispuestos en el interior de los alojamientos 14, de manera que pueden girar, pero no pueden salirse de los mismos accidentalmente, lo que permite regular la inclinación de las toberas 3 para que el agua se extienda de la forma deseada. Una vez determinada está inclinación, se procede a la fijación definitiva de los manguitos 17, en sus alojamientos 14 mediante sendos tornillos de fijación (no representados) .In figure 4 it can be seen how the pairs of nozzles 3 are fixed to the windshield 2. On the windshield 2 a plate 15 provided with an adhesive sheet 16 is fixed, said plate 15 comprising a housing 14 integral thereto. Inside said housing 14, a sleeve 17 is provided in pairs of nozzles 3. Each pair of nozzles 3 comprises two sleeves 17 to make the coupling more stable. The sleeves 17 are arranged inside the housings 14, so that they can rotate, but cannot accidentally come out of them, which allows to regulate the inclination of the nozzles 3 so that the water spreads in the desired way. Once this inclination is determined, the sleeves 17 are finally fixed in their housings 14 by means of two fixing screws (not shown).
A los manguitos 17 citados también van acoplados los conductos 13, los cuales se fijan al contorno del parabrisas, de manera que exteriormente se confundan con la junta de los mismos.To the aforementioned sleeves 17 are also coupled the ducts 13, which are fixed to the contour of the windshield, so that they are confused externally with the gasket thereof.
En una realización alternativa al sistema representado, en la figura 1, el sistema de la invención puede comprender un depósito propio con el fluido adecuado, que puede ser agua o anticongelante. - 9 -In an alternative embodiment to the system shown, in Figure 1, the system of the invention may comprise a reservoir of its own with the appropriate fluid, which may be water or antifreeze. - 9 -
Para accionar el sistema de la invención, el conductor deberá accionar momentáneamente (señal de ráfaga) la luz de carretera 12 al poner en marcha el motor. En ese momento el agua procedente del depósito 8, impulsada por la bomba 7, accederá al interior del recinto 9 donde se calentará mediante la resistencia 4. Una vez calentada, el agua será impulsada a los pares de toberas 3 alternativamente mediante la válvula 5. El accionamiento de todos estos componentes está comandado por el dispositivo de control 6. El conductor deberá acelerar suavemente hasta que se alcancen 1.400 r.p.m., manteniéndolo a este régimen durante el tiempo que dure el calentamiento. Inmediatamente, el agua calentada saldrá por las toberas 3 y se extenderá sobre el parabrisas 2, descongelando el hielo acumulado sobre el mismo o desempañándolo. Una vez finalizada la salida del agua, el conductor deberá accionar el limpiaparabrisas para retirar el agua que haya quedado sobre el parabrisas 2. El tiempo estimado para que se extienda toda el agua caliente sobre el parabrisas desde el momento que el conductor acciona el motor y la luz de carretera es de unos 30 segundos .To drive the system of the invention, the driver must momentarily activate (burst signal) the high beam 12 when starting the engine. At that time, the water from the reservoir 8, driven by the pump 7, will enter the interior of the enclosure 9 where it will be heated by the resistance 4. Once heated, the water will be propelled to the pairs of nozzles 3 alternately by the valve 5. The drive of all these components is commanded by the control device 6. The driver must accelerate smoothly until 1,400 rpm is reached, maintaining it at this rate during the time the heating lasts. Immediately, the heated water will flow out of the nozzles 3 and spread over the windshield 2, defrosting the ice accumulated on it or defrosting it. Once the water exit is finished, the driver must activate the windshield wiper to remove the remaining water on the windshield 2. The estimated time for all hot water to spread on the windshield from the moment the driver starts the engine and the road light is about 30 seconds.
Para impedir que quede agua en el interior de los conductos, la bomba 7 es reversible y autoaspirante, vaciando automáticamente el agua de los conductos al final del proceso y evitando así su congelación. To prevent water from being left inside the ducts, the pump 7 is reversible and self-aspirating, automatically emptying the water from the ducts at the end of the process and thus preventing freezing.
