Description
La présente invention concerne un dispositif permettant d'obtenir un liquide de lave-glace chaud à la demande. The present invention relates to a device for obtaining a hot washer fluid on demand.
En effet, par temps froid, les conducteurs de véhicules automobiles sont très souvent confrontés, lorsqu'ils laissent leur voiture dehors, à la présence de givre (ou de glace) à la surface de leurs vitres avant et arrière. Ceci empêche toute visibilité, et les conducteurs doivent alors retirer ce givre. Indeed, in cold weather, motor vehicle drivers are very often confronted, when they leave their car outside, with the presence of frost (or ice) on the surface of their front and rear windows. This prevents visibility, and drivers must remove this frost.
Pour ce faire, le conducteur est le plus souvent dans la nécessité de gratter les vitres à l'aide d'objets rigides. Or ce travail est long, d'un résultat imparfait, et surtout pénible.To do this, the driver is most often in the need to scratch the windows using rigid objects. However this work is long, of an imperfect result, and especially painful.
La présente invention permet de remédier à ce problème en rendant possible l'élimination naturelle du givre par l'utilisation du liquide de lave-glace projeté à volonté sur les vitres et simultanément porté à haute température. The present invention overcomes this problem by making possible the natural elimination of frost by the use of windshield washer fluid sprayed at will on the windows and simultaneously brought to high temperature.
Plusieurs dispositifs ont été auparavant conçus pour chauffer le liquide de lave-glace, comme ceux utilisant la chaleur du liquide de refroidissement du moteur ou celle de l'échappement. Néanmoins, outre leur complexité de réalisation, ces systèmes ne mettent pas à disposition immédiate un liquide de lave-glace chaud. Several devices have been previously designed to heat the washer fluid, such as those using the heat of the engine coolant or that of the exhaust. However, in addition to their complexity of construction, these systems do not immediately provide a hot washer fluid.
Des dispositifs basés sur l'utilisation d'une résistance chauffante alimentée par la batterie du véhicule ont aussi été conçus, mais ils présentent d'importantes difficultés de réalisation du fait, en particulier, de l'usinage des pièces nécessaire pour obtenir une étanchéité convenable. Devices based on the use of a heating resistor supplied by the vehicle battery have also been designed, but they present significant difficulties of realization due, in particular, to the machining of the parts necessary to obtain a suitable seal. .
La présente invention permet de résoudre ces problèmes, en présentant une résistance chauffante d'une réalisation très aisée, et permettant de chauffer le liquide de lave-glace immédiatement et à la demande. The present invention makes it possible to solve these problems, by presenting a heating resistance which is very easy to produce, and making it possible to heat the washer fluid immediately and on demand.
La présente invention consiste en une résistance électrique chauffante (bloc chauffant) alimentée par la batterie et intégrée au système de circulation hydraulique de lave-glace du véhicule. The present invention consists of an electric heating resistor (heating block) powered by the battery and integrated into the vehicle washer hydraulic circulation system.
Ce bloc chauffant est constitué d'un tube métallique de faible diamètre (d'un diamètre similaire à celui des canalisations du liquide de lave-glace) et de faible épaisseur de parois. Ce tube est enroulé sur lui-même en spirale plane, simple ou multiple, et est recouvert extérieurement d'une couche de matière isolante. L'ensemble est placé dans un boitier aussi isolant. This heating block consists of a small diameter metal tube (of a diameter similar to that of the windshield washer fluid pipes) and of small wall thickness. This tube is wound on itself in a flat spiral, single or multiple, and is covered externally with a layer of insulating material. The whole is placed in a case also insulating.
La spirale est connectée, à chacune de ses extrémités métallique, à des fils électriques reliés aux bornes de la batterie. Ainsi, lorsqu'une différence de potentiel est appliquée à ces fils, le courant traverse le métal de la spirale, et sa résistance électrique intrinsèque produit de la chaleur par effet
Joule. A une extrémité de cette spirale tubulaire est introduit le liquide de lave-glace froid (du fait du débit normalement assuré par la pompe d'alimentation), et à l'autre extrémité, on recueille le liquide chaud quand le courant traverse la spirale.The spiral is connected, at each of its metal ends, to electrical wires connected to the terminals of the battery. So when a potential difference is applied to these wires, the current flows through the metal of the spiral, and its intrinsic electrical resistance produces heat by effect.
Joule. At one end of this tubular spiral is introduced the cold windshield washer fluid (due to the flow normally provided by the feed pump), and at the other end, the hot liquid is collected when the current flows through the spiral.
Le liquide est chauffé du fait des transferts thermiques entre lui et les parois de la spirale métallique chaude, lors du transit de la veine liquide dans la spirale. The liquid is heated due to the heat transfers between it and the walls of the hot metallic spiral, during the transit of the liquid vein in the spiral.
Selon un mode de réalisation particulier, la paroi interne du tube en spirale peut être aussi recouverte d'une couche de matériau électriquement isolant, et les matières isolantes utilisées doivent pouvoir supporter les hautes températures engendrées par la résistance électrique. According to a particular embodiment, the internal wall of the spiral tube can also be covered with a layer of electrically insulating material, and the insulating materials used must be able to withstand the high temperatures generated by the electrical resistance.
Les dessins annexés illustrent l'invention. La figure 1 présente le schéma général d'installation du dispositif, et la figure 2 présente le bloc chauffant. The accompanying drawings illustrate the invention. Figure 1 shows the general installation diagram of the device, and Figure 2 shows the heating block.
En référence à ces dessins, le bloc chauffant (1) est constitué d'un boitier (2) électriquement isolant. Ce boitier contient la spirale métallique tubulaire (3) entourée de son isolant électrique (4). Des connections électriques sont placées en (5), permettant l'arrivée du courant de la batterie, et sont mises en contact avec chacune des extrémités métalliques de la spirale. Chacune de ces extrémité (6) dépasse légèrement de l'enceinte (2) de manière à permettre les connections hydrauliques. La figure 1 présente une configuration hydraulique et électrique de montage du dispositif dans laquelle le bloc chauffant est placé en aval de la pompe d'alimentation du liquide (7), et où un contacteur spécifique (8) est disposé au tableau de bord du véhicule. With reference to these drawings, the heating block (1) consists of an electrically insulating housing (2). This box contains the tubular metal spiral (3) surrounded by its electrical insulator (4). Electrical connections are placed at (5), allowing the arrival of current from the battery, and are brought into contact with each of the metal ends of the spiral. Each of these ends (6) protrudes slightly from the enclosure (2) so as to allow the hydraulic connections. FIG. 1 shows a hydraulic and electrical configuration for mounting the device in which the heating block is placed downstream of the liquid supply pump (7), and where a specific contactor (8) is arranged on the vehicle dashboard .
Selon cette configuration, soit le conducteur, en situation habituelle, n'actionne que le commodo de lave-glace (9), auquel cas la pompe (7) débite le liquide à travers le bloc chauffant (1) non alimenté électriquement, et du liquide à température ambiante est projeté en (10) sur les vitres; soit en situation de givre, le conducteur actionne le commodo spécifique (8). Dans ce cas, la pompe (7) débite le liquide à travers le bloc alimenté simultanément en électricité et devenant donc très chaud. Le liquide pulvérisé sera alors presque instantanément chaud. According to this configuration, either the driver, in the usual situation, operates only the windshield washer switch (9), in which case the pump (7) delivers the liquid through the heating block (1) which is not electrically supplied, and liquid at room temperature is sprayed in (10) on the windows; either in a frost situation, the driver actuates the specific commodo (8). In this case, the pump (7) delivers the liquid through the block supplied simultaneously with electricity and therefore becoming very hot. The sprayed liquid will then be almost instantly hot.
Selon un mode de réalisation particulier, deux blocs chauffant peuvent être utilisés de manière à alimenter respectivement les vitres avant et arrière du véhicule. D'autre part, le bloc chauffant sera placé plus efficacement le plus près possible des gicleurs extérieurs (10) afin de réduire les pertes thermiques après chauffage. Ensuite, du fait que ce dispositif est destiné à être utilisé principalement au démarrage du véhicule, sa mise en fonctionnemment sera plus utilement effectuée par une commande particulière. Néanmoins, une évolution de la configuration électrique du dispositif peut être adoptée en plaçant un thermostat. Le thermostat accouplera alors, selon les températures extérieures, le chauffage du liquide à la commande de pulvérisation. Ensuite, le système électrique, dans un mode de réalisation particulier, peut être tel que le dispositif ne puisse être mis en marche qu'après démarrage du moteur; et une sécurité peut être disposée afin de prévenir tout court-circuit dû à la destruction des isolants. Enfin, on peut disposer, en sortie du bloc chauffant, des canalisations supportant des températures pouvant être temporairement élevées. La température du liquide en sortie du bloc chauffant est déterminée le plus simplement par construction, en fonction des résistance et longueur de la spirale. According to a particular embodiment, two heating blocks can be used so as to supply the front and rear windows of the vehicle respectively. On the other hand, the heating block will be placed more efficiently as close as possible to the external nozzles (10) in order to reduce the heat losses after heating. Then, because this device is intended to be used mainly when starting the vehicle, it will functionally be put into operation more usefully by a particular command. However, an evolution of the electrical configuration of the device can be adopted by placing a thermostat. The thermostat will then couple, depending on the outside temperatures, the heating of the liquid to the spray control. Then, the electrical system, in a particular embodiment, can be such that the device can only be started after starting the engine; and a safety device can be provided to prevent any short circuit due to the destruction of the insulators. Finally, it is possible to have, at the outlet of the heating block, pipes supporting temperatures which may be temporarily high. The temperature of the liquid leaving the heating block is determined most simply by construction, depending on the resistance and length of the spiral.
La présente invention est plus particulièremet destinée aux véhicules automobiles. Elle peut être soit directement montée en usine, soit distribuée sous forme de kit à monter. Le kit est facilement adaptable au véhicule par simple connection au circuit hydraulique de lave-glace, et par montage électrique très simple. The present invention is more particularly intended for motor vehicles. It can either be directly assembled in the factory, or distributed in the form of a kit to be assembled. The kit is easily adaptable to the vehicle by simple connection to the hydraulic washer system, and by very simple electrical mounting.
