Description

Objet de l'inventionSubject of the invention

La présente invention est dans le domaine des appareils de chauffage étanches à combustible liquide, en particulier les appareils de chauffage à mazout.The present invention is in the field of watertight liquid fuel heaters, in particular especially oil heaters.

Arrière-plan technologique et état de la technique à la base de l'inventionTechnological background and state of the art at the basis of the invention

Actuellement, un grand nombre de maisons anciennes comportent des cheminées non adaptées, n'autorisant pas un tirage efficace adapté aux appareils de chauffage actuellement fabriqués et nécessitant selon les normes européennes des rendements supérieurs à 80%.Currently, a large number of houses old ones have unsuitable chimneys, not authorizing an efficient draft suitable for heating currently manufactured and requiring according to European standards for yields above 80%.

Cependant, pour assurer ce rendement de chauffage, il est nécessaire que les cheminées des bâtiments, en particulier des habitations, présentent un tirage suffisant (mais pas trop fort ou débouchant éventuellement dans une zone de vent plongeant) pour assurer une combustion efficace.However, to ensure this yield of heating, it is necessary that the chimneys of buildings, especially dwellings, have a sufficient draft (but not too strong or open possibly in a downwind zone) for ensure efficient combustion.

En outre, un grand nombre d'habitations modernes ne comprennent pas de cheminée et/ou sont basés sur l'utilisation de systèmes de chauffage électriques coûteux.In addition, a large number of dwellings modern do not include a fireplace and / or are based on the use of electric heating systems expensive.

Souvent, les consommateurs souhaitent rajouter un système de chauffage d'appoint, en particulier un poêle à mazout.Consumers often wish add an additional heating system, in particular an oil stove.

Par conséquent, il existe un besoin pour des appareils de chauffage à combustible liquide pouvant être adaptés sur des structures portantes extérieures à l'habitation à chauffer, en particulier sur les murs extérieurs des habitations à chauffer, tout en permettant un "tirage" correct des gaz brûlés issus de la combustion.Therefore, there is a need for liquid fuel heaters which may be adapted on load-bearing structures outside the house to be heated, especially on the walls exteriors of homes to be heated, while allowing a correct "draft" of the burnt gases from the combustion.

Les nouveaux appareils étanches utilisant le gaz comme combustible et dénommés appareils étanches à ventouse, fixés sur le mur extérieur d'une habitation à chauffer et par où se fait l'évacuation des gaz issus de la combustion ainsi que l'alimentation en gaz comburant (air) ont été largement commercialisés ces dernières années. Ceux-ci ont eu un grand succès étant donné que les utilisateurs craignaient d'éventuels dangers suite à la combustion du gaz et parce qu'une ventouse murale permet d'installer un radiateur ou un appareil de chauffage contre un mur extérieur, simplement en perçant un trou dans le mur et sans nécessiter la construction d'une cheminée.New waterproof devices using the gas as fuel and referred to as airtight devices suction cup, fixed on the outside wall of a house heat and where the gases from the combustion as well as the supply of oxidizing gas (air) have been widely marketed in recent years. These have been very successful since the users feared possible dangers from the combustion of gas and because a wall suction cup allows install a radiator or heater against an exterior wall, simply by drilling a hole in the wall and without requiring the construction of a chimney.

Dans ce type d'appareil, la double buse mettant en communication le radiateur ou l'appareil de chauffage à gaz et l'extérieur de la pièce ou de l'habitation à chauffer est essentiellement horizontale et n'amène aucun tirage pour faire fonctionner l'appareil de chauffage.In this type of device, the double nozzle connecting the radiator or the gas heating and the outside of the room or the house to be heated is essentially horizontal and does not cause any drawdown to operate the heater.

Dans un appareil à gaz à flamme bleue, c'est l'injection du gaz dans un venturi de brûleur atmosphérique qui sert de "moteur" à l'aspiration du gaz comburant (air).In a blue flame gas appliance, it is injecting gas into an atmospheric burner venturi which serves as an "engine" for the suction of the oxidizing gas (air).

De plus, dans un appareil de chauffage classique à gaz raccordé à une cheminée, un coupe tirage est toujours monté en sortie d'appareil, la cheminée ne servant qu'à éliminer les gaz issus de la combustion et n'ayant pas de rôle moteur pour l'alimentation en comburant. In addition, in a heater classic gas connected to a chimney, a draft cut is always fitted at the appliance outlet, the chimney does not used only to remove gases from combustion and not having a driving role for the supply of oxidizer.

Dans le cas des appareils de chauffage à combustible liquide, en particulier des systèmes à mazout, à pétrole ou à huile végétale, la combustion provoque la formation d'un certain nombre de composés aromatiques (si le tirage est excessif ou si le poêle est mal conçu ou mal réglé), ainsi que la formation et éventuellement le dépôt de poussières et de suie (si le tirage est insuffisant) et résultant d'une mauvaise combustion.In the case of space heaters liquid fuel, in particular oil systems, with petroleum or vegetable oil, combustion causes formation of a number of aromatic compounds (if the draft is excessive or if the stove is badly designed or badly settled), as well as training and possibly filing dust and soot (if the draft is insufficient) and resulting from poor combustion.

De tels problèmes ne se présentent pas avec les appareils de chauffage à gaz, étant donné que les produits résultant de la combustion sont du gaz carbonique et de la vapeur d'eau.Such problems do not arise with gas heaters, since the products resulting from combustion are carbon dioxide and water vapor.

Dans les appareils à combustible liquide à caléfaction, le tirage de la cheminée est donc primordial et est source de tous les ennuis d'installation.In liquid fuel appliances with heating, the chimney draft is therefore essential and is the source of all installation troubles.

En effet, c'est cette cheminée qui entraíne l'air comburant à travers les injecteurs d'un pot brûleur et un tirage insuffisant amène une production de suie, tandis qu'un tirage trop fort conduit à la destruction du catalyseur et à la production de gaz CO au ralenti.Indeed, it is this fireplace that leads the combustion air through the injectors of a burner pot and insufficient draft leads to soot production, while too strong a draw leads to the destruction of the catalyst and the production of CO gas at idle.

Buts de l'inventionAims of the invention

La présente invention vise à fournir un appareil de chauffage de type étanche basé sur l'utilisation d'un combustible liquide ne nécessitant pas le raccordement des systèmes d'évacuation des gaz à une cheminée.The present invention aims to provide a waterproof type heater based on the use of liquid fuel that does not require connection of exhaust gas systems to a fireplace.

La présente invention vise à fournir un tel appareil de chauffage qui soit caractérisé par un rendement efficace, qui n'occasionne pas de risques d'insécurité pour le consommateur et qui ne nécessite pas de ventilation de la pièce à chauffer.The present invention aims to provide such heater characterized by efficiency effective, which does not pose risks of insecurity for the consumer and which does not require ventilation of the room to be heated.

Eléments caractéristiques de l'inventionCharacter-defining elements of the invention

La présente invention est relative à un appareil de chauffage étanche à combustible liquide (c'est-à-dire un appareil de chauffage à mazout, à pétrole, à huile végétale,...) dans lequel les moyens d'évacuation des gaz brûlés issus de la combustion de ce combustible liquide, ainsi que les moyens d'alimentation en gaz comburant (air) sont montés directement sur une structure extérieure, tel qu'un mur extérieur éventuellement porteur ou le toit extérieur, par rapport à la pièce ou à l'habitation à chauffer et sans nécessiter de raccordement à une cheminée.The present invention relates to a waterproof liquid fuel heater (i.e. an oil, oil, in vegetable oil, ...) in which the means of evacuation burnt gases from the combustion of this fuel liquid, as well as the gas supply means oxidizer (air) are mounted directly on a structure exterior, such as a possibly load-bearing exterior wall or the outer roof, relative to the room or the house to be heated and without requiring a connection to a fireplace.

On entend par appareil de chauffage étanche, un appareil de chauffage qui ne nécessite pas de moyen d'alimentation en gaz comburant depuis l'intérieur de l'habitation ou de la pièce à chauffer, l'appareil de chauffage étanche étant protégé de l'atmosphère de l'habitation ou de la pièce à chauffer par une double enveloppe assurant une étanchéité totale.The term "sealed heater" means a heater that does not require means supply of oxidant gas from inside home or room to be heated, the appliance sealed heating being protected from the atmosphere of the house or the room to be heated by a double envelope ensuring total tightness.

L'appareil de chauffage à combustible liquide portant le repère de référence général 1 dans les figures annexées 1 à 3 comporte un brûleur à caléfaction 2, une chambre de combustion 3, dans laquelle l'air comburant est entraíné au travers d'un pot brûleur 4.The liquid fuel heater bearing the general reference mark 1 in the figures attached 1 to 3 includes a heat burner 2, a combustion chamber 3, in which the combustion air is driven through a burner pot 4.

L'appareil de chauffage 1 est conçu de sorte que l'injection d'air dans ce pot brûleur 4 est compris dans un rapport de combustion d'environ 1 à 3, de préférence de 1 à 4, par rapport à un appareil de chauffage à combustible liquide raccordé de manière classique à une cheminée.The heater 1 is designed so that the injection of air into this burner pot 4 is understood in a combustion ratio of about 1 to 3, of preferably 1 to 4, compared to a heater with liquid fuel conventionally connected to a fireplace.

L'appareil de chauffage de l'invention est également avantageusement pourvu d'un catalyseur 15 en acier réfractaire permettant de stabiliser la flamme dans le brûleur à caléfaction 2 de l'appareil de chauffage de l'invention. The heater of the invention is also advantageously provided with a catalyst 15 in refractory steel to stabilize the flame in the heat burner 2 of the space heater the invention.

De préférence, les moyens d'évacuation des gaz brûlés issus de la combustion, ainsi que les moyens d'alimentation en gaz comburant (air), montés directement sur la structure portante extérieure 5, tel qu'un mur extérieur, sont constitués d'une double buse pour l'amenée des gaz comburants et l'évacuation des gaz brûlés issus de la combustion, cette double buse (élément éventuellement coudé comme représenté à la Fig. 3) étant avantageusement constituée de deux cylindres 6, 7, de préférence emboítés l'un dans l'autre (ou éventuellement parallèles l'un à l'autre), le cylindre intérieur 6 permettant l'évacuation des gaz brûlés issus de la combustion et l'espace annulaire entre le cylindre intérieur 6 et le cylindre extérieur 7 permettant l'alimentation en gaz comburant (air) destiné à la combustion dans l'appareil de chauffage 1.Preferably, the means of evacuation of burnt gases from combustion, as well as the means supply of oxidant gas (air), mounted directly on the external supporting structure 5, such as a wall outside, consist of a double nozzle for the supply oxidizing gases and the discharge of burnt gases from combustion, this double nozzle (element possibly bent as shown in FIG. 3) being advantageously consisting of two cylinders 6, 7, preferably fitted one inside the other (or possibly parallel to each other the other), the inner cylinder 6 allowing the evacuation burnt gases from combustion and the annular space between the inner cylinder 6 and the outer cylinder 7 allowing the supply of oxidizing gas (air) intended for combustion in the heater 1.

La partie terminale de cette structure cylindrique est avantageusement recouverte par une ventouse 8 fixée sur la structure portante extérieure 5, permettant d'éviter la formation de perturbations et de tourbillons provoqués éventuellement par le vent projeté vers ladite structure portante 5.The terminal part of this structure cylindrical is advantageously covered by a suction cup 8 fixed on the outer bearing structure 5, allowing avoid the formation of disturbances and vortices possibly caused by the wind projected towards said supporting structure 5.

Cette ventouse 8 est conçue et disposée sur la structure portante extérieure 5, de manière à permettre que l'extrémité 9 du tube cylindrique intérieur 6 déborde par rapport à la structure portante extérieure 5, mais déborde également par rapport à l'extrémité 10 du second cylindre extérieur 7, comme illustré dans la Fig. 3.This suction cup 8 is designed and arranged on the outer bearing structure 5, so as to allow that the end 9 of the inner cylindrical tube 6 extends beyond with respect to the external supporting structure 5, but also overflows from end 10 of the second outer cylinder 7, as illustrated in FIG. 3.

L'appareil de chauffage comprend également un dispositif d'amenée 11 de combustible liquide, dispersé par gravitation naturelle ou amené à la chambre de combustion 3 par tout dispositif d'injection ou autre, l'appareil de chauffage comprenant un régulateur de débit 12, muni éventuellement d'une sécurité de débordement 13.The heater also includes a liquid fuel supply device 11, dispersed by natural gravitation or brought to the combustion chamber 3 by any injection or other device, the heating comprising a flow regulator 12, provided possibly an overflow safety device 13.

Le réglage de la puissance de combustion de l'appareil de chauffage de l'invention s'effectue par l'utilisateur en fonction de la position d'une manette de commandement ou d'un activateur thermostatique.Adjusting the combustion power of the heater of the invention is carried out by the user depending on the position of a joystick command or thermostatic activator.

L'air comburant est entraíné au niveau du pot brûleur 4 à travers une série de perforations 14 par le tirage des dispositifs d'évacuation des gaz de combustible brûlé, plus précisément par la différence de poids entre une colonne des section unitaire d'air comburant et une colonne de section unitaire de gaz brûlés issus de la combustion.The combustion air is entrained at the level of the pot burner 4 through a series of perforations 14 through the drawing of fuel gas evacuation devices burned, more precisely by the difference in weight between a column of unitary combustion air sections and a column section unit burnt gases from the combustion.

Cette configuration permet également un tirage efficace des gaz brûlés issus de la combustion.This configuration also allows efficient draft of burnt gases from combustion.

Comme le gaz comburant (air entrant) s'échauffe dans la partie annulaire entre le cylindre extérieur 7 et le cylindre intérieur 6, au contact des gaz brûlés issus de la combustion et sortant par le cylindre intérieur 6, la différence de pression entre l'amont et l'aval de l'injecteur d'air au niveau du pot brûleur 4 est d'environ 1/3 de ce qu'elle est dans un appareil à cheminée classique où la colonne d'air entrant est à température ambiante, une modification du pot brûleur 4 selon l'invention permet de maintenir une combustion efficace.Like oxidizing gas (incoming air) heats up in the annular part between the cylinder outside 7 and the inside cylinder 6, in contact with gases burnt from combustion and exiting through the cylinder interior 6, the pressure difference between upstream and the downstream side of the air injector at the burner pot 4 is about 1/3 of what it is in a fireplace classic where the incoming air column is at temperature ambient, a modification of the burner pot 4 according to the invention makes it possible to maintain efficient combustion.

Dans ce cas, l'énergie cinétique disponible pour l'injection est de l'ordre de 1/3 de ce qu'elle est dans un système classique raccordé à une cheminée.In this case, the kinetic energy available for injection is around 1/3 of what it is in a classic system connected to a chimney.

L'énergie (1/3 de ϕv2) est proportionnelle au carré de la vitesse et à la densité. Par conséquent, il est nécessaire d'injecter le même volume de gaz comburant (air entrant) par unité de temps (si l'on admet que la densité n'a que faiblement changé), la vitesse d'injection de l'appareil étanche est de l'ordre de 1/3 de ce qu'elle est dans un appareil de chauffage classique. Par conséquent, le pot brûleur 4 de l'appareil de chauffage de l'invention est modifié pour que la section globale de tous les injecteurs du pot brûleur soit augmentée d'un rapport d'environ la racine carrée de 3, soit d'environ 1,7 par rapport à un appareil classique (avec raccordement sur cheminée) comparable. Si l'on considère que le débit d'air comburant est à peu près égal à celui d'un appareil classique, la vitesse est modifiée et, par une modification des pots brûleurs selon l'invention, on observe un équilibre permettant une combustion efficace. Ceci évite la déstabilisation de la flamme, ainsi qu'une formation de dérivés de combustion pouvant provoquer la formation de poussière et le dépôt de suie. De manière à satisfaire aux conditions mathématiques susmentionnées, le pot brûleur 4 de l'invention a été modifié par la formation d'une répartition d'une perforation de taille différente, telle que des perforations de grande taille à côté de perforations de petite taille, éventuellement en alternance, ou une succession de perforations de petite taille en alternance dans l'étage le plus bas du pot brûleur 4.The energy (1/3 of ϕv 2 ) is proportional to the square of the speed and the density. Therefore, it is necessary to inject the same volume of oxidant gas (incoming air) per unit of time (if we admit that the density has changed only slightly), the injection speed of the sealed device is around 1 / 3 of what it is in a conventional heater. Consequently, the burner pot 4 of the heater of the invention is modified so that the overall section of all the injectors of the burner pot is increased by a ratio of approximately the square root of 3, or by approximately 1.7 compared to a conventional appliance (with chimney connection) comparable. If we consider that the combustion air flow is roughly equal to that of a conventional appliance, the speed is modified and, by a modification of the burners according to the invention, a balance is observed allowing efficient combustion . This avoids the destabilization of the flame, as well as the formation of combustion derivatives which can cause the formation of dust and the deposit of soot. In order to satisfy the aforementioned mathematical conditions, the burner pot 4 of the invention has been modified by the formation of a distribution of a perforation of different size, such as large perforations next to small perforations, possibly alternately, or a succession of small perforations alternately in the lowest stage of the burner pot 4.

Les données mathématiques susmentionnées sont conçues pour une référence de 8 pieds de hauteur d'un appareil de chauffage étanche.The aforementioned mathematical data are designed for a reference of 8 feet in height of a waterproof heater.

Cependant, les caractéristiques de l'appareil de chauffage étanche de l'invention peuvent être adaptées à d'autres conditions sur base de l'enseignement de la présente description par l'homme du métier.However, the characteristics of the device heating elements of the invention can be adapted to other conditions based on teaching the present description by the skilled person.

Le dispositif de chauffage étanche de l'invention est également caractérisé par un haut rendement garantissant une faible production de gaz CO, en particulier inférieure aux limites des normes européennes et canadiennes (normes EN1 européenne et B140.3 canadienne).The waterproof heater of the invention is also characterized by high efficiency guaranteeing a low production of CO gas, by particular below the limits of European standards and Canadian (EN1 European and B140.3 standards Canadian).
