Abstract

The liquefied petroleum gas (LPG) device, fixed directly to a disposable gas cartridge or a rechargeable container, has a burner (9) and injector (6) - tap (7) group on the cartridge. It also has a temperature regulating system with a thermal insulator (13), while the burner is suspended over the injector-tap group with no direct contact between them. The burner interacts with a thermal conductor which has heat receiving (10a) and release (10b) sections to transfer heat to the cartridge. The device also has a thermal shield (8a) between the heat utilizer (3) and the injector and which is traversed by the burner. The heat utilizer can have an open flame or be in the form of a lamp with a wind shield.

Description

La présente invention concerne un appareil portatif à gaz G.P.L. fixé directement sur cartouches jetables ou sur réservoirs rechargeables, applicable à un utilisateur thermique, du type qui comprend un brûleur du gaz émit par l'injecteur du robinet monté sur la cartouche.The present invention relates to a portable gas appliance G.P.L. fixed directly on disposable cartridges or on refillable tanks, applicable to a thermal user, of the type which includes a burner of the gas emitted by the valve injector mounted on the cartridge.

La présente invention s'applique principalement aux fours portatifs pour la cuisson des céramiques, des émaux sur métaux, ou pour la fusion de verre et métaux, utilisés pour l'artisanat artistique et le hobby. Actuellement, à cause des problèmes exposés ci-dessous, les brûleurs de ces fours portatifs, fixés directement sur un récipient de G.P.L., ne peuvent pas utiliser des cartouches jetables mais seulement des réservoirs rechargeables, beaucoup plus grands et plus lourds. Un exemple connu fait l'objet du brevet G. Santilli IT 1 214 778 / USA 4 628 895 / etc.The present invention mainly applies to portable ovens for firing ceramics, enamels on metals, or for melting glass and metals, used for artistic crafts and hobby. Currently, because of the problems outlined below, the burners of these portable ovens, fixed directly on a container of G.P.L., cannot use cartridges disposable but only refillable tanks, much larger and heavier. A known example is the subject of patent G. Santilli IT 1,214,778 / USA 4 628 895 / etc.

Actuellement, les appareils portatifs sans détendeur ni tube, mais fixé directement sur une cartouche jetable, et non sur un réservoir rechargeable, sont appliqués en camping pour l'illumination et la cuisson des aliments, ou dans le bricolage pour toutes les utilisations d'une flamme libre, par exemple pour la soudure ou pour l'enlèvement des vieilles peintures. Dans ces domaines également, la présente invention représente une solution originale à des problèmes courants.Currently, portable devices without regulator or tube, but fixed directly on a disposable cartridge, and not on a refillable tank, are applied when camping for lighting and cooking food, or in DIY for all uses of an open flame, for example for welding or removing old paints. In these areas also, the present invention represents an original solution to common problems.

Pendant le fonctionnement de ces appareils, le gaz passe de l'état liquide à l'état gazeux. Un tel changement d'état génère du froid à l'intérieur de la cartouche de gaz. Si la puissance désirée requiert trop de gaz gazeux en relation avec la quantité de gaz liquide disponible, le froid ainsi généré ralenti la gazéification.During the operation of these devices, the gas changes from the liquid state to the state gaseous. Such a change of state generates cold inside the cartridge gas. If the desired power requires too much gaseous gas in relation to the quantity of liquid gas available, the cold thus generated slows gasification.

Ce phénomène limite la puissance des brûleurs que l'on peut monter sur une dimension de cartouche donnée, et réduit la puissance réellement fournie par le brûleur au fur et à mesure que le gaz s'épuise.This phenomenon limits the power of the burners that can be mounted on a given cartridge size, and reduces the power actually supplied by the burner as the gas runs out.

En particulier, ce problème empêche l'utilisation de cartouches jetables pour chauffer les fours portatifs pour céramique et verre, à cause de la grande quantité d'énergie requise. La seule solution courante consiste à augmenter la quantité de gaz disponible, en choisissant des bouteilles de gaz beaucoup plus grandes et plus lourdes, du type rechargeable.In particular, this problem prevents the use of disposable cartridges for heat portable ovens for ceramic and glass, due to the large amount of energy required. The only common solution is to increase the amount of gas available, choosing much more gas cylinders large and heavier, of the rechargeable type.

Le froid de l'environnement accélère et augmente le phénomène décrit ci-dessus. Le facteur climatique limite l'utilisation en plein air de tels appareils, et peut l'empêcher totalement en hiver, ou dans les pays froids, ou en montagne.The cold of the environment accelerates and increases the phenomenon described above. The climatic factor limits the outdoor use of such devices, and can prevent it completely in winter, or in cold countries, or in Mountain.

Dans ce type d'appareil, le brûleur est toujours fixé à un groupe métallique qui comprend un injecteur, un robinet et un branchement pour cartouche. La chaleur transmise par conduction par le brûleur limite la durée d'élément d'importance vitale, ce qui pose un problème de sécurité. En particulier, les éléments qui peuvent se détériorer sont les joints en caoutchouc du robinet et la micro-valve de plastique présente sur de nombreux modèles de cartouches jetables.In this type of appliance, the burner is always attached to a metal group which includes an injector, a tap and a cartridge connection. The heat transmitted by conduction by the burner limits the element duration of vital importance, which poses a security problem. In particular, items that can deteriorate are the rubber seals of the valve and the plastic micro-valve found on many models of cartridges disposable.

Ce problème exclut que l'on puisse utiliser des cartouches jetables pour chauffer des fours portatifs pour céramique et verre, à cause de la grande quantité d'énergie transmise par conduction du brûleur vers les joints de caoutchouc et la micro-valve. This problem precludes the use of disposable cartridges for heat portable ovens for ceramic and glass, due to the large amount of energy transmitted by conduction from the burner to the seals of rubber and micro-valve.

Une des solutions adoptées pour résoudre le problème de la sécurité est une limitation de puissance de l'appareil de la part du constructeur. Un tel renoncement naít également de la considération commune que, de toutes façons, la puissance serait limitée par le froid généré ou par le froid de l'environnement.One of the solutions adopted to solve the security problem is a power limitation of the device on the part of the manufacturer. Such renunciation also comes from the common consideration that, of all ways, the power would be limited by the cold generated or by the cold of the environment.

Le problème de la sécurité est un obstacle majeur à la miniaturisation de plus en plus poussée requise par le marché. Dans les solutions courantes, les éléments sensibles restent à une certaine distance des éléments chauds, ou bien sont séparés par un tuyau métallique ou en caoutchouc. Un appareil fixé directement sur cartouche jetable ne peut pas être miniaturisé au delà d'une certaine limite. Ce problème est senti en particulier dans le domaine des fours pour céramique et verre de type portatif, à cause de la grande quantité de chaleur transmise par conduction.The security problem is a major obstacle to further miniaturization in addition push required by the market. In common solutions, the sensitive elements remain at a certain distance from the hot elements, or are separated by a metal or rubber hose. A fixed device directly on disposable cartridge cannot be miniaturized beyond a certain limit. This problem is felt particularly in the field of ovens for ceramic and portable type glass, due to the large amount of heat transmitted by conduction.

Les cartouches jetables utilisées en camping contiennent en général du butane.The disposable cartridges used in camping generally contain butane.

S'agissant d'un gaz G.P.L. à basse pression, le butane est particulièrement sensible aux chutes de pression causées par le froid. Pour résoudre ce problème, certains constructeurs proposent des cartouches remplies avec un mélange butane-propane, ou avec du propane pur. Le propane est un gaz G.P.L. à haute pression, donc moins sujet aux chutes de pression causées par le froid. La majeure pression est cependant à l'origine de coûts de production plus élevés pour ce qui est de la cartouche.As a G.P.L. at low pressure, butane is particularly sensitive to pressure drops caused by cold. To resolve this problem, some manufacturers offer cartridges filled with a butane-propane mixture, or with pure propane. Propane is a gas G.P.L. at high pressure, therefore less subject to pressure drops caused by cold. The major pressure is however at the origin of production costs higher for the cartridge.

Le but de la présente invention, ainsi qu'elle est caractérisée dans les revendications ci-jointes, est donc d'éliminer tous les inconvénients mentionnés grâce à un système thermorégulateur formé par la combinaison de deux dispositifs, l'un thermoconducteur, l'autre thermoisolant, opposés et complémentaires.The object of the present invention, as characterized in attached claims, is therefore to eliminate all the disadvantages mentioned thanks to a thermoregulatory system formed by the combination of two devices, one thermally conductive, the other thermally insulating, opposite and complementary.

Le premier dispositif thermoconducteur conduit une juste quantité de chaleur à la cartouche pour maintenir le gaz à température et pression utiles. Ceci permet d'augmenter la puissance disponible en conditions normales et de maintenir la puissance en conditions extrêmes. Le deuxième dispositif thermoisolant consiste en un brûleur suspendu devant l'injecteur. Cette solution empêche la conduction de chaleur du brûleur au groupe robinet-cartouche, permettant ainsi d'augmenter la puissance et la miniaturisation, sans risque pour les éléments plus sensibles à la chaleur du groupe robinet-cartouche.The first thermally conductive device conducts the right amount of heat to the cartridge to maintain the gas at useful temperature and pressure. This increases the power available under normal conditions and maintain power in extreme conditions. The second device thermal insulation consists of a burner suspended in front of the injector. This solution prevents the conduction of heat from the burner to the tap-cartridge group, thus allowing to increase the power and the miniaturization, without risk for the elements more sensitive to the heat of the valve-cartridge group.

D'autres caractéristiques et avantages ressortiront plus clairement de la description détaillée qui suit, faite en référence aux dessins ci-joints, qui en représentent une forme à simple titre d'exemple non limitatif dans lesquels les figures 1, 2, 3 et 4 indiquent la présente invention selon quatre applications distinctes.Other characteristics and advantages will emerge more clearly from the detailed description which follows, made with reference to the attached drawings, which represent a form by way of nonlimiting example in which the Figures 1, 2, 3 and 4 indicate the present invention according to four applications separate.

En particulier, dans les dessins ci-joints, en 1 est indiqué l'ensemble de l'appareil portatif à gaz G.P.L. réalisé selon l'invention, fixé directement sur la cartouche 2 de gaz, utilisé pour chauffer un utilisateur thermique 3, éventuellement posé sur un support 4.In particular, in the attached drawings, in 1 is indicated the set of the portable gas appliance G.P.L. made according to the invention, fixed directly to the gas cartridge 2, used to heat a thermal user 3, possibly placed on a support 4.

Dans la figure 1, l'utilisateur thermique 3 est un four pour céramique, verre ou métaux; dans la figure 2, il s'agit d'une lampe 11 de camping; dans la figure 3, il s'agit d'une casserole pour la cuisson des aliments. Dans la figure 4, l'utilisateur thermique est une flamme libre utilisée dans le bricolage pour la soudure ou pour l'enlèvement des vieilles peintures.In FIG. 1, the thermal user 3 is an oven for ceramic, glass or metals; in Figure 2, it is a camping lamp 11; in figure 3, it is a pan for cooking food. In Figure 4, the thermal user is an open flame used in DIY for the welding or for removing old paints.

L'appareil 1 comprend un dispositif thermoconducteur 10, qui conduit la juste quantité de chaleur des zones chaudes de l'appareil à la cartouche 2. Ce dispositif est doté d'une extrémité 10a de captation de la chaleur, et d'une extrémité 10b de diffusion de la chaleur.The apparatus 1 comprises a thermally conductive device 10, which conducts the right amount of heat from the hot zones of the device to the cartridge 2. This device has a heat capture end 10a, and a heat diffusion end 10b.

L'extrémité 10b enveloppe de façon opportune la cartouche 2, à laquelle elle diffuse de la chaleur.The end 10b appropriately wraps the cartridge 2, to which it diffuses heat.

Dans les figures 1 et 2, l'extrémité 10a recueille la chaleur irradiée par la bouche à feu 3a du four ou par la lampe 11. Dans la figure 3, l'extrémité 10a se trouve avantageusement sur la flamme du brûleur 9. Dans la figure 4, l'extrémité 10a enveloppe et soutient le brûleur 9.In FIGS. 1 and 2, the end 10a collects the heat irradiated by the fire hearth 3a from the oven or by the lamp 11. In FIG. 3, the end 10a is advantageously located on the burner flame 9. In FIG. 4, the end 10a envelops and supports the burner 9.

Avantageusement, le dispositif 10 est en métal, amovible, d'épaisseur et de dimensions variables afin que l'on puisse moduler la quantité de chaleur conduite à la cartouche 2, en fonction des utilisations et des conditions de l'environnement, et afin que l'on puisse adapter l'appareil à divers modèles de cartouches.Advantageously, the device 10 is made of metal, removable, of thickness and of variable dimensions so that we can modulate the amount of heat lead to cartridge 2, depending on the uses and conditions of environment, and so that the device can be adapted to various models of cartridges.

Ce dispositif 10 maintient à température et pression utiles, le gaz contenu dans la cartouche 2. Ce dispositif permet ainsi d'utiliser ce type d'appareil dans un environnement froid, ou permet de brancher des appareils plus puissants sur une cartouche donnée, ou permet d'augmenter la quantité de gaz émis et la vitesse d'émission à partir d'une cartouche donnée.This device 10 maintains at useful temperature and pressure, the gas contained in cartridge 2. This device thus allows this type of device to be used in a cold environment, or allows more powerful devices to be connected to a given cartridge, or increases the amount of gas emitted and the transmission speed from a given cartridge.

L'appareil 1 comprend en outre un dispositif thermoisolant 13, constitué par une séparation entre le brûleur 9 d'un coté, et l'injecteur 6 avec robinet 7 de l'autre.The apparatus 1 further comprises a thermal insulation device 13, constituted by a separation between the burner 9 on one side, and the injector 6 with tap 7 of the other.

On interrompt ainsi le pont thermique entre des éléments qui sont unit dans la technique connue.This breaks the thermal bridge between elements which are united in the known technique.

En effet, le brûleur 9 n'est fixé en aucune façon à l'injecteur 6 ou au robinet 7, mais à d'autres éléments de l'appareil. Par exemple, dans la figure 1, le brûleur 9 est fixé à un bouclier thermique 8a qui protège tous les éléments sous-jacents de la chaleur irradiés par la bouche à feu 3a du four, selon le brevet Santilli IT 1 214 778/USA 4 628 895/ etc. Dans la figure 2, le brûleur 9 est fixé au support 8b du verte 12 de la lampe 11.Indeed, the burner 9 is in no way fixed to the injector 6 or to the tap 7, but to other parts of the device. For example, in Figure 1, the burner 9 is attached to a heat shield 8a which protects all the underlying elements from the heat radiated by the mouth fire 3a from the oven, according to Santilli IT 1,214,778 / USA 4,628,895 / etc. In FIG. 2, the burner 9 is fixed to the support 8b of the green 12 of the lamp 11.

Dans la figure 3, le brûleur est fixé ad un pare-vent 8c. Dans la figure 4, le brûleur est fixé à l'extrémité 10a du dispositif thermoconducteur 10.In Figure 3, the burner is attached to a wind screen 8c. In Figure 4, the burner is fixed to the end 10a of the thermally conductive device 10.

Dans les figures 1, 2, 3, le dispositif thermoisolant 13 concerne une séquence verticale cartouche 2-robinet 7-injecteur 6-brûleur 9. Dans la figure 4, ce dispositif est appliqué à une séquence à angle droit, mais d'autres solutions sont possibles.In FIGS. 1, 2, 3, the thermal insulation device 13 relates to a sequence vertical cartridge 2-tap 7-injector 6-burner 9. In Figure 4, this device is applied to a right angle sequence but other solutions are possible.

Un tel dispositif thermoisolant 13 permet donc d'augmenter au maximum la puissance du brûleur et de pousser à l'extrême la miniaturisation de l'appareil 1, en toute sécurité pour les parties moins résistantes à la chaleur, en particulier les joints de caoutchouc du robinet 7 et la micro-valve 5 de la cartouche 2.Such a heat insulating device 13 therefore makes it possible to increase the burner power and take the miniaturization of the appliance to the extreme 1, safe for parts less resistant to heat, in particular the rubber seals of the tap 7 and the micro-valve 5 of the cartridge 2.

Ces deux dispositifs 10 et 13, séparables mentalement, ne sont pas indépendants du point de vue de leur fonctionnement. Ils fonctionnent en effet comme un unique système thermorégulateur: l'action de l'un est facilitée ou rendue possible par l'action de l'autre. La puissance du brûleur 9 suspendu est utilisable seulement parce que le dispositif thermoconducteur 10 maintient le gaz de la cartouche 2 à température et pression utiles; celui ci peut augmenter en toute sécurité la température et la pression du gaz seulement grâce au dispositif thermoisolant 13, dans lequel le brûleur 9, étant suspendu, ne peut pas surchauffer les éléments plus sensibles à la chaleur du groupe robinet 7-cartouche 2, surtout quand la chaleur de l'environnement rendrait dangereux ce genre de dispositif. These two devices 10 and 13, mentally separable, are not independent from the point of view of their operation. They work indeed as a single thermoregulatory system: the action of one is facilitated or made possible by the action of the other. The power of the suspended burner 9 is usable only because the thermally conductive device 10 maintains the gas from cartridge 2 at useful temperature and pressure; this one can increase safely the temperature and pressure of the gas only thanks to the heat insulating device 13, in which the burner 9, being suspended, cannot not overheat the elements more sensitive to the heat of the tap group 7-cartridge 2, especially when the heat of the environment makes it dangerous this kind of device.

Si le dispositif thermoconducteur 10 n'existait pas, la majeure puissance du brûleur 9 suspendu ou le froid de l'environnement causerait une chute de pression du gaz et de la puissance fournie. Vice versa, en présence du dispositif thermoconducteur 10, si le brûleur 9 n'était pas suspendu, mais en contact avec le groupe robinet 7-cartouche 2, comme c'est toujours le cas dans ce genre d'appareil, la chaleur transmise par conduction endommagerait les joints de caoutchouc du robinet 7 et la micro-valve 5 de la cartouche 2.If the thermally conductive device 10 did not exist, the major power of the 9 burner suspended or the cold of the environment would cause a fall of gas pressure and power supplied. Vice versa, in the presence of the device thermally conductive 10, if the burner 9 was not suspended, but in contact with the 7-cartridge 2 tap group, as is always the case in this genre the heat transmitted by conduction would damage the seals of rubber of tap 7 and micro-valve 5 of cartridge 2.

L'invention ainsi conçue est susceptible de nombreuses modifications et variantes, qui entrent toutes dans le cadre du concept inventif exprimé ci-après.The invention thus conceived is susceptible of numerous modifications and variants, all of which fall within the scope of the inventive concept expressed below.
