Definitions
- the invention relates to the field of cooking appliances. domestic comprising at least one gas burner, and in particular ovens gas, gas hobs and gas stoves.
- Household cooking appliances generally include one or more gas burners supplied by one or more injectors.
- the injector determines the amount of combustible gas entering the burner.
- the power of the burner tends to decrease.
- This decrease in burner power has its origin in the decrease in the amount of combustible gas entering the burner by time unit.
- One of the main causes of this decrease is the rise in temperature of the injector which causes the gas to expand fuel in the injector causing in turn the decrease in the quantity combustible gas entering the burner.
- the power of the burner being proportional to the quantity of combustible gas passing through the injector in a given time interval, the power of the burner then tends to decrease.
- the causes of the rise in temperature of the injector reside in especially in the high temperature of the burner and other parts of domestic cooking appliance that is not thermally isolated from the burner and which communicate their heat to the injector.
- the injector and burner have relative to each other a determined relative position that a sufficiently rigid intermediate support is responsible for maintaining.
- the intermediate support supports the injector and maintains this relative position by connecting the injector to the burner, either directly or indirectly by through metallic or thermally structured elements conductors located in the vicinity of the burner.
- the intermediate support is thermally conductive material, usually metal. So the intermediate support establishes a thermal bridge between the injector and the burner.
- a first solution would be to delete the existing thermal bridge between the injector and the burner, replacing the intermediate support made of metallic material by a support intermediate made of insulating material, so that the heat located at the burner is not communicated to the injector and the injector remains relatively cold compared to the temperature of the burner.
- a second solution would consist in carrying out an injector made of insulating material so that the inside of the injector stays relatively cold compared to the burner temperature.
- a third solution consists in cutting the bridge thermal by retaining an intermediate support which can even be possibly made of thermally conductive material, the support intermediate connecting the injector to one or more parts of the domestic cooking which are thermally insulated from the burner. These parts keep, when the domestic cooking appliance is in operation, a relatively cold temperature compared to the temperature of the burner.
- This solution has, over the two previous solutions, in particular the advantage to be simpler and less expensive by allowing the use of a material inexpensive for making the intermediate support, like a metal for example, which has sufficient stiffness properties for maintain the relative position of the injector relative to the burner, in order to that the burner supply is not disturbed. Insulating material having good temperature resistance and good rigidity, as in the first or second solution, would certainly cost more.
- a domestic cooking appliance comprising at least one gas burner, at least one injector supplying the gas burner, at least one intermediate support supporting the injector and being rigid enough to maintain the relative position of the injector by relative to the burner, characterized in that the intermediate support connects the injector to one or more parts of the device which are thermally isolated from the burner.
- the part or parts of the home cooking appliance that are thermally insulated from the burner must not or hardly transmit the heat from the burner to the injector, even if the intermediate support is produced in a thermally conductive material such as a metal for example. These parts must therefore remain at a relatively cold temperature by relative to the burner temperature, during appliance operation domestic cooking, while the burner temperature becomes high. These parts are not themselves directly connected to the burner by a element or chain of thermally conductive elements susceptible to transmit a significant amount of heat. These parts are not in the immediate vicinity of the burner, in the vicinity of which a significant amount of heat, which would make them almost as hot as the burner itself.
- the parts of the device are sufficiently thermally isolated from the burner and on the other hand the materials constituting the intermediate support have a conductivity sufficiently low thermal so that, in operating mode, at after ten minutes, the injector remains at a temperature between 10 ° C and 40 ° C, which corresponds approximately to the temperature room.
- the burner reaches easily a temperature of 100 ° C, for example after ten minutes.
- the operating mode is for example a cooking mode.
- FIG. 1 schematically shows a partially view exploded view of a preferred embodiment of a cooking appliance domestic according to the invention.

- a mitt 11 consists of a cavity 1 into which the food is introduced and of walls 2 which surround the cavity 1.
- Under the muffle 11, is located a box sole 3 comprising one or more gas burners not shown on the Figure 1.
- the sole box 3 generally made of metal is not thermally isolated from the gas burner (s).
- the sole box 3 has a orifice 4 for entry of the gaseous fluid generally consisting of gas fuel and atmospheric primary air.

These parts do not are not the muffle 11, that is to say are not the walls 2 of the muffle 11. These parts are not the sole box 3. These parts are not one of the parts which is connected to the burner by a thermally conductive bridge like orifice 4 for example.
- the intermediate support 12 connects the injector 5 to the external structure of the furnace 13. This external structure, constituted by the outer walls 10 and the uprights 9, remains generally relatively cold compared to the burner temperature in operating mode, because it is thermally isolated from the burner.

Description
L'invention concerne le domaine des appareils de cuisson domestique comportant au moins un brûleur à gaz, et notamment les fours gaz, les tables de cuisson gaz et les cuisinières gaz.The invention relates to the field of cooking appliances. domestic comprising at least one gas burner, and in particular ovens gas, gas hobs and gas stoves.
Les appareils de cuisson domestique comportent généralement un ou plusieurs brûleurs à gaz alimentés par un ou plusieurs injecteurs. L'injecteur détermine la quantité de gaz combustible entrant dans le brûleur. Or, pendant l'opération de cuisson, la puissance du brûleur a tendance à diminuer. Cette diminution de la puissance du brûleur a son origine dans la diminution de la quantité de gaz combustible entrant dans le brûleur par unité de temps. Une des causes principales de cette diminution est l'élévation en température de l'injecteur qui entraíne une dilatation du gaz combustible dans l'injecteur entraínant à son tour la diminution de la quantité de gaz combustible entrant dans le brûleur. La puissance du brûleur étant proportionnelle à la quantité de gaz combustible passant dans l'injecteur dans un intervalle de temps donné, la puissance du brûleur a alors tendance à diminuer.Household cooking appliances generally include one or more gas burners supplied by one or more injectors. The injector determines the amount of combustible gas entering the burner. However, during the cooking operation, the power of the burner tends to decrease. This decrease in burner power has its origin in the decrease in the amount of combustible gas entering the burner by time unit. One of the main causes of this decrease is the rise in temperature of the injector which causes the gas to expand fuel in the injector causing in turn the decrease in the quantity combustible gas entering the burner. The power of the burner being proportional to the quantity of combustible gas passing through the injector in a given time interval, the power of the burner then tends to decrease.
Selon l'art antérieur connu, ce problème n'est, en réalité, pas résolu. En effet, dans la pratique, lorsque la puissance du brûleur diminue, on augmente le débit de gaz combustible alimentant l'injecteur ; ainsi, la puissance du brûleur est rétablie, mais au prix d'une consommation plus élevée en gaz combustible et donc en énergie.According to the known prior art, this problem is, in reality, not resolved. Indeed, in practice, when the power of the burner decreases, increasing the flow of combustible gas supplying the injector; so the burner power is restored, but at the cost of more consumption high in combustible gas and therefore in energy.
Pour résoudre le problème de la diminution de puissance du brûleur en fonction de la température du brûleur et de l'injecteur, il apparaít donc intéressant de résoudre le problème de l'élévation en température de l'injecteur.To solve the problem of the decrease in power of the burner depending on the temperature of the burner and the injector, it appears therefore interesting to solve the problem of the rise in temperature of the injector.
Les causes de l'élévation en température de l'injecteur résident en particulier dans la température élevée du brûleur et d'autres parties de l'appareil de cuisson domestique qui ne sont pas thermiquement isolées du brûleur et qui communiquent à l'injecteur leur chaleur. L'injecteur et le brûleur ont l'un par rapport à l'autre une position relative déterminée qu'un support intermédiaire suffisamment rigide est chargé de maintenir. Le support intermédiaire supporte l'injecteur et maintient cette position relative en reliant l'injecteur au brûleur, soit directement, soit indirectement par l'intermédiaire des éléments de structure métalliques ou thermiquement conducteurs situés dans le voisinage du brûleur. Le support intermédiaire est en matériau thermiquement conducteur, généralement en métal. Ainsi, le support intermédiaire établit un pont thermique entre l'injecteur et le brûleur. Lorsque l'appareil de cuisson comporte plusieurs brûleurs alimentés par plusieurs injecteurs, les injecteurs sont généralement reliés aux brûleurs par plusieurs supports intermédiaires.The causes of the rise in temperature of the injector reside in especially in the high temperature of the burner and other parts of domestic cooking appliance that is not thermally isolated from the burner and which communicate their heat to the injector. The injector and burner have relative to each other a determined relative position that a sufficiently rigid intermediate support is responsible for maintaining. The intermediate support supports the injector and maintains this relative position by connecting the injector to the burner, either directly or indirectly by through metallic or thermally structured elements conductors located in the vicinity of the burner. The intermediate support is thermally conductive material, usually metal. So the intermediate support establishes a thermal bridge between the injector and the burner. When the cooking appliance has several burners supplied by several injectors, the injectors are generally connected to the burners by several intermediate supports.
Une première solution, non revendiquée, consisterait à supprimer le pont thermique existant entre l'injecteur et le brûleur en remplaçant le support intermédiaire constitué en matériau métallique par un support intermédiaire constitué en matériau isolant, de manière à ce que la chaleur située au niveau du brûleur ne soit pas communiquée à l'injecteur et que l'injecteur reste relativement froid par rapport à la température du brûleur.A first solution, not claimed, would be to delete the existing thermal bridge between the injector and the burner, replacing the intermediate support made of metallic material by a support intermediate made of insulating material, so that the heat located at the burner is not communicated to the injector and the injector remains relatively cold compared to the temperature of the burner.
Une deuxième solution, non revendiquée, consisterait à réaliser un injecteur en matériau isolant de manière à ce que l'intérieur de l'injecteur reste relativement froid par rapport à la température du brûleur.A second solution, not claimed, would consist in carrying out an injector made of insulating material so that the inside of the injector stays relatively cold compared to the burner temperature.
Une troisième solution, revendiquée, consiste à couper le pont thermique en conservant un support intermédiaire qui peut même être éventuellement réalisé en matériau thermiquement conducteur, le support intermédiaire reliant l'injecteur à une ou plusieurs parties de l'appareil de cuisson domestique qui sont thermiquement isolées du brûleur. Ces parties conservent, lorsque l'appareil de cuisson domestique est en fonctionnement, une température relativement froide par rapport à la température du brûleur. Cette solution a, sur les deux précédentes solutions, notamment l'avantage d'être plus simple et moins coûteuse en permettant l'utilisation d'un matériau bon marché pour la réalisation du support intermédiaire, comme un métal par exemple, qui présente des propriétés de rigidité suffisantes pour maintenir la position relative de l'injecteur par rapport au brûleur, ceci afin que l'alimentation du brûleur ne soit pas perturbée. Un matériau isolant présentant une bonne tenue à la température et une bonne rigidité, comme dans la première ou la deuxième solution, coûterait certainement plus cher.A third solution, claimed, consists in cutting the bridge thermal by retaining an intermediate support which can even be possibly made of thermally conductive material, the support intermediate connecting the injector to one or more parts of the domestic cooking which are thermally insulated from the burner. These parts keep, when the domestic cooking appliance is in operation, a relatively cold temperature compared to the temperature of the burner. This solution has, over the two previous solutions, in particular the advantage to be simpler and less expensive by allowing the use of a material inexpensive for making the intermediate support, like a metal for example, which has sufficient stiffness properties for maintain the relative position of the injector relative to the burner, in order to that the burner supply is not disturbed. Insulating material having good temperature resistance and good rigidity, as in the first or second solution, would certainly cost more.
Selon l'invention, il est prévu un appareil de cuisson domestique comportant au moins un brûleur à gaz, au moins un injecteur alimentant le brûleur à gaz, au moins un support intermédiaire supportant l'injecteur et étant suffisamment rigide pour maintenir la position relative de l'injecteur par rapport au brûleur, caractérisé en ce que le support intermédiaire relie l'injecteur à une ou plusieurs parties de l'appareil qui sont thermiquement isolées du brûleur.According to the invention, there is provided a domestic cooking appliance. comprising at least one gas burner, at least one injector supplying the gas burner, at least one intermediate support supporting the injector and being rigid enough to maintain the relative position of the injector by relative to the burner, characterized in that the intermediate support connects the injector to one or more parts of the device which are thermally isolated from the burner.
L'invention sera mieux comprise et d'autres particularités et avantages apparaítront à l'aide de la description ci-après et des dessins joints, donnés à titre d'exemples, où la figure 1 représente schématiquement une vue partiellement éclatée d'un mode de réalisation préférentiel d'un appareil de cuisson domestique selon l'invention.The invention will be better understood and other features and advantages will appear from the following description and from the drawings seals, given as examples, where Figure 1 schematically represents a partially exploded view of a preferred embodiment of a domestic cooking appliance according to the invention.
La ou les parties de l'appareil de cuisson domestique qui sont thermiquement isolées du brûleur ne doivent pas ou peu transmettre la chaleur du brûleur à l'injecteur, même si le support intermédiaire est réalisé en un matériau thermiquement conducteur comme un métal par exemple. Ces parties doivent donc rester à une température relativement froide par rapport à la température du brûleur, pendant le fonctionnement de l'appareil de cuisson domestique, alors que la température du brûleur devient élevée. Ces parties ne sont pas elles-mêmes directement reliées au brûleur par un élément ou une chaíne d'éléments thermiquement conducteurs susceptibles de transmettre une quantité de chaleur importante. Ces parties ne sont pas au voisinage immédiat du brûleur, voisinage vers lequel est transmise une quantité de chaleur importante, ce qui aurait pour effet de les rendre presque aussi chaudes que le brûleur lui-même.The part or parts of the home cooking appliance that are thermally insulated from the burner must not or hardly transmit the heat from the burner to the injector, even if the intermediate support is produced in a thermally conductive material such as a metal for example. These parts must therefore remain at a relatively cold temperature by relative to the burner temperature, during appliance operation domestic cooking, while the burner temperature becomes high. These parts are not themselves directly connected to the burner by a element or chain of thermally conductive elements susceptible to transmit a significant amount of heat. These parts are not in the immediate vicinity of the burner, in the vicinity of which a significant amount of heat, which would make them almost as hot as the burner itself.
De préférence, d'une part les parties de l'appareil sont suffisamment thermiquement isolées du brûleur et d'autre part le ou les matériaux constituant le support intermédiaire possèdent une conductivité thermique suffisamment faible, pour que, en mode de fonctionnement, au bout d'une dizaine de minutes, l'injecteur reste à une température comprise entre 10°C et 40°C, ce qui correspond approximativement à la température ambiante. Dans ce même mode de fonctionnement, le brûleur atteint facilement une température de 100°C, par exemple au bout d'une dizaine de minutes. Le mode de fonctionnement est par exemple un mode cuisson.Preferably, on the one hand, the parts of the device are sufficiently thermally isolated from the burner and on the other hand the materials constituting the intermediate support have a conductivity sufficiently low thermal so that, in operating mode, at after ten minutes, the injector remains at a temperature between 10 ° C and 40 ° C, which corresponds approximately to the temperature room. In this same operating mode, the burner reaches easily a temperature of 100 ° C, for example after ten minutes. The operating mode is for example a cooking mode.
La figure 1 représente schématiquement une vue partiellement
éclatée d'un mode de réalisation préférentiel d'un appareil de cuisson
domestique selon l'invention. L'appareil de cuisson représenté sur la figure 1
est un four gaz 13 mais l'invention peut également s'appliquer aux tables de
cuisson gaz ou aux cuisinières gaz comme décrit ultérieurement. Un moufle
11 est constitué d'une cavité 1 dans laquelle sont introduits les aliments et
de parois 2 qui entourent la cavité 1. Sous le moufle 11, est située une boíte
sole 3 comprenant un ou plusieurs brûleurs à gaz non représentés sur la
figure 1. La boíte sole 3 généralement réalisée en métal n'est pas
thermiquement isolée du ou des brûleurs à gaz. La boíte sole 3 comporte un
orifice 4 d'entrée du fluide gazeux généralement constitué de gaz
combustible et d'air primaire atmosphérique. L'orifice 4 est de préférence
l'entrée convergente d'un Venturi qui est par exemple située à l'extérieur de
la boíte sole 3. En regard de l'orifice 4, est maintenu en position un injecteur
5 porté par un porte-injecteur 6 lui-même porté par un élément de liaison 7
reliant le porte-injecteur 6 à une ou plusieurs parties du four qui sont
thermiquement isolées du brûleur. L'injecteur 5 est relié à un dispositif
d'alimentation en gaz combustible par un tube 8 d'alimentation en gaz. Dans
le cas où la boíte sole 3 comporte plusieurs brûleurs, il peut bien sûr y avoir
plusieurs injecteurs 5, plusieurs porte-injecteurs 6, plusieurs éléments de
liaison 7. Le support intermédiaire 12 comprend le porte-injecteur 6 et
l'élément de liaison 7. Le support intermédiaire 12 sera décrit en détail
ultérieurement. Le moufle 11 et la boíte sole 3 sont à l'intérieur de la
structure externe du four qui est généralement constitué de montants 9 et de
parois extérieures 10. Un seul montant 9 et une seule paroi extérieure 10
sont représentés sur la figure 1.Figure 1 schematically shows a partially view
exploded view of a preferred embodiment of a cooking appliance
domestic according to the invention. The cooking appliance shown in Figure 1
is a

parties du four 13 qui sont thermiquement isolées du brûleur. Ces parties ne
sont pas le moufle 11, c'est-à-dire ne sont pas les parois 2 du moufle 11.
Ces parties ne sont pas la boíte sole 3. Ces parties ne sont pas l'une des
pièces qui est reliée au brûleur par un pont thermiquement conducteur
comme l'orifice 4 par exemple. De préférence, le support intermédiaire 12
relie l'injecteur 5 à la structure externe du four 13. Cette structure externe,
constituée par les parois extérieures 10 et les montants 9, reste
généralement relativement froide par rapport à la température du brûleur en
mode de fonctionnement, car elle est thermiquement isolée du brûleur. The
L'appareil de cuisson domestique selon l'invention peut aussi être
par exemple une table de cuisson gaz non représentée. La table de cuisson
gaz comporte un carter qui comprend un ou plusieurs brûleurs à gaz. Le
support intermédiaire 12 relie l'injecteur 5 à une ou plusieurs parties de la
table de cuisson qui ne sont pas le brûleur. Ces parties ne sont pas les
pièces reliées au brûleur par un pont thermiquement conducteur. Ces pièces
sont par exemple le collecteur ou la partie convergente du Venturi du brûleur
qui ne sont pas représentés sur la figure 1. De préférence, le support
intermédiaire 12 relie l'injecteur 5 au carter de la table de cuisson et en
particulier aux parties les plus froides du carter de la table de cuisson.The domestic cooking appliance according to the invention can also be

Le support intermédiaire 12 comporte un porte-injecteur 6 portant
l'injecteur 5 et un élément de liaison 7 reliant le porte-injecteur 6 à une ou
plusieurs parties de l'appareil qui sont thermiquement isolées du brûleur.The

porte-injecteur 6 et l'élément de liaison 7 forment ensemble une structure
monobloc.In one embodiment of the
Dans un mode de réalisation préférentielle du support
intermédiaire 12, le porte-injecteur 6 et l'élément de liaison 7 sont deux
pièces distinctes. Dans ce mode de réalisation, l'élément de liaison 7,
distinct du porte-injecteur 6, présente l'avantage d'être compatible avec
différents types d'injecteurs 5 et de porte-injecteurs 6. Le même élément de
liaison 7 autorise également différents types de réglage d'injecteur 5 et de
porte-injecteur 6, ces différents réglages se traduisant par différentes
distances entre injecteur 5 et brûleur, plus précisément ici entre injecteur 5 et
orifice 4 de brûleur.In a preferred embodiment of the
