Description

ENCEINTE DE CUISSON A ENERGIE ELECTRIQUE
La présente invention concerne une enceinte de cuisson à énergie électrique, comportant un moufle muni d'au moins un élément de chaufrage do sole, une turbine de circulation -d'air placée dans la paroi arrière du moufle, une plaque diffuseur orientant l'air pulsé dans le moufle, un dispositif de commutation électrique comportant des contacts pour la mise sous tension sélective des éléments de chauffage do solo et de la turbine.ELECTRIC ENERGY COOKING CABINET
The present invention relates to an electrically powered cooking chamber, comprising a muffle provided with at least one heating element do sole, an air-circulation turbine placed in the rear wall of the muffle, a diffuser plate orienting the air pulsed in the muffle, an electrical switching device comprising contacts for the selective energization of the heating elements do solo and the turbine.

Cette enceinte de cuisson i énergie électrique comporte donc au moins un élément de chauffage de sole et une turbine de circulation d'air, mais elle peut également comporter en plus au moins un élément de chauffage de plafond et un élément de chauffage ventilé par la circulation de l'air de la turbine pour constituer une enceinte de cuisson moderne équipée de tous ces éléments chauffants. This electric energy cooking chamber therefore comprises at least one hearth heating element and an air circulation turbine, but it can also additionally comprise at least one ceiling heating element and one heating element ventilated by circulation. air from the turbine to form a modern cooking chamber equipped with all these heating elements.

Le dispositif de coimutation de cette enceinte de cuisson permet à l'utilisateur de programmer plusieurs positions adaptées chacune à une cuisson particulière. The coimutation device of this cooking enclosure allows the user to program several positions each adapted to a particular cooking.

On connaît une première position appelée "conventionnelle" permettant la lise sous tension exclusive des éléments de plafond et des éléments de solo, pour cuire de façon satisfaisante des viandes et de façon moins bonne des pâtisseries, mais présentant surtout un inconvénient majeur qui est l'impossibilité de cuire à plusieurs niveaux de façon correcte. We know a first position called "conventional" allowing the reading under exclusive tension of the ceiling elements and solo elements, to cook satisfactorily meats and not so good pastries, but especially presenting a major drawback which is the inability to cook on several levels correctly.

On connaît une deuxième position appelée "à chaleur tournante", permettant la lise sous tension de l'élément de chauffage ventilé et de la turbine pour cuire de anière satisfaisante les patisaeries seches, mais pas les pâtisseries humides par exemple les tartes à fruits à patte, feuilletée ou brisée car les fonds de ces tartes ne sont pas assez cuits. De plus, dans cette position à chaleur tournante, la repar- tition horizontale de l'énergie n'est pas aussi bonne que l'on pourrait le souhaiter. A second position known as "fan heat" is known, allowing the reading under tension of the ventilated heating element and of the turbine for baking dry patiseries in a satisfactory manner, but not wet pastries, for example fruit pies with legs. , flaky or broken because the bottoms of these pies are not cooked enough. Furthermore, in this fan-cooled position, the horizontal distribution of the energy is not as good as one might wish.

On connaît également une position particulière appelée "gril pulsé qui permet la lise sous tension d'au moins un élément de chauf- fage do plafond et de la turbine de circulation d'air. There is also a particular position known as a "pulsed grill" which allows the reading under tension of at least one ceiling heating element and of the air circulation turbine.

Cette position donne satisfaction pour les viandes, notamment les viandes blanches, mais des résultats médiocres pour les pâtisseries. This position is satisfactory for meats, especially white meats, but poor results for pastries.

La présente invention permet de remédier à ces inconvénients en proposant une enceinte de cuisson comportant une position adaptée aussi bien à la cuisson des viandes que des pâtisseries sèches ou humides, car la chaleur produite par convection et rayonnement par les éléments do sole ost bien répartie dans l'enceinte de cuisson par l'action du ventilateur. The present invention makes it possible to remedy these drawbacks by proposing a cooking chamber comprising a position suitable both for cooking meats and for dry or wet pastries, since the heat produced by convection and radiation by the elements do sole is well distributed in the cooking chamber by the action of the fan.

Cette position ost particulièrement avantageuse dans le cas où les éléments de sole sont placés à l'extérieur du moufle, car on évite un rayonnement direct de ces éléments sur le produit à cuire,permettant ainsi une coloration parfaite et uniforme, notamment des viandes. This position is particularly advantageous in the case where the sole elements are placed outside the muffle, since this avoids direct radiation of these elements on the product to be cooked, thus allowing perfect and uniform coloring, in particular of meats.

Elle permet également de supprimer le préchauffage réalisant ainsi une économie d'énergie substantielle et une économie de temps pour l'utilisateur. It also eliminates preheating, thereby achieving substantial energy savings and time savings for the user.

La présente invention a donc pour objet une enceinte de cuisson à énergie électrique, comportant un soufle snni d'au moins un élément de chauffage de solo, une turbine de circulation d'air placée dans la paroi arrière du moufle, une plaque diffuseur orientant l'air pulsé dans le moufle, un dispositif de commutation électrique comportant des contacts pour la lise sous tension sélective des éléments de chauffage de sole et do la turbine, caractérisée en ce que le dispositif de commutation comporte une position selon laquelle au moins un élément do chauffage de sole est branché en parallèle avec la turbine de ofronlation d'air. The present invention therefore relates to an electrically powered cooking chamber, comprising a breath provided with at least one solo heating element, an air circulation turbine placed in the rear wall of the muffle, a diffuser plate orienting the pulsed air in the muffle, an electrical switching device comprising contacts for the selective energization of the floor heating elements and of the turbine, characterized in that the switching device has a position according to which at least one element floor heating is connected in parallel with the air ofronlation turbine.

De préférence, dans le cas où il est prévu deux éléments de sole, le dispositif de commutation comporte une position selon laquelle ces deux éléments de sole sont branchés en parallèle, la turbine de circulation d'air étant branchée en parallèle sur l'ensemble. Preferably, in the case where two floor elements are provided, the switching device comprises a position according to which these two floor elements are connected in parallel, the air circulation turbine being connected in parallel to the assembly.

n est décrit Ci-après, à titre d'exemple et On référence aux figures du dessin annexé, une enceinte de cuisson permettant la mise en ceurre de l'invention. n is described below, by way of example and with reference to the figures of the appended drawing, a cooking chamber allowing the buttering of the invention.

La figure 1 représente, on perspective, une vue simplifiée de l'enceinte de cuisson. Figure 1 shows, in perspective, a simplified view of the cooking chamber.

La figure 2 représente une coupe verticale de cette enceinte de
Cuisson.Figure 2 shows a vertical section of this enclosure of
Cooking.

La figure 3 représente de manière simplifiée, un schéma électrique de l'enceinte de cuisson, dans lequel ne sont représentés que les éléments nécessaires à la lise en oeuvre de l'invention. Figure 3 shows in a simplified manner, an electrical diagram of the cooking chamber, in which are shown only the elements necessary for the implementation of the invention.

flans la figure 1, le moufle 1 délimite par sa paroi supérieure 2, Sa paroi inférieure 3, sa paroi arrière 4 et ses deux parois latérales 5, 6, une cavité de cuisson 7, ce moufle étant bien entendu fermé sur sa partie avant par une porte (non représentée), au cours d'une cuisson. blanks in Figure 1, the muffle 1 delimited by its upper wall 2, its lower wall 3, its rear wall 4 and its two side walls 5, 6, a cooking cavity 7, this muffle being of course closed on its front part by a door (not shown), during cooking.

Dans sa partie arrière, lieux visible en figure 2, est montée une turbine 8 entranée par un moteur électrique 9 et séparée de la cavité de cuisson 7 par une plaque diffuseur 11 percée en sa partie centrale d'orifices d'aspiration 12. In its rear part, places visible in FIG. 2, is mounted a turbine 8 driven by an electric motor 9 and separated from the cooking cavity 7 by a diffuser plate 11 pierced in its central part with suction orifices 12.

L'air entraSné par la turbine est refoulé dans la cavité de cuisson le long des parois latérales 5, 6 du moufle. The air driven by the turbine is discharged into the cooking cavity along the side walls 5, 6 of the muffle.

Des éléments de chauffage de sole 20, 21 (appelés aussi résistances de sole), sont disposés en-dessous de la paroi inférieure 3 du moufle 1. Ces éléments de chauffage de sole peuvent, bien sur être disposés au-dessus de la paroi inférieure du moufle, c'est-à-dire dans le moufle. Sole heating elements 20, 21 (also called sole resistors) are arranged below the bottom wall 3 of the muffle 1. These sole heating elements can, of course, be placed above the bottom wall of the muffle, that is to say in the muffle.

Comme cela a été représenté dans les figures 1 et 2, à titre illustratif et nullement limitatif, l'enceinte peut comporter au moins un élément de chauffage de plafond 30, 31 et un élément de chauffage ventilé 10 par la circulation de l'air de la turbine. As shown in Figures 1 and 2, by way of illustration and in no way limitative, the enclosure may include at least one ceiling heating element 30, 31 and a heating element ventilated 10 by the circulation of air from the turbine.

La figure 3 montre un schéma simplifié ne représentant que les liements nécessaires à la mise en oeuvre de l'invention, et dans le cas d'une enceinte de cuisson comportant au moins un élément de chauffage de volte et un élément de chauffage ventilé, ceus-ci ne seraient évidaient pas sous tension. FIG. 3 shows a simplified diagram representing only the connections necessary for the implementation of the invention, and in the case of a cooking chamber comprising at least one volte heating element and one ventilated heating element, ceus - these would obviously not be under tension.

Les différents éléments de chauffage et de ventilation utilisés dans cette position particulière sont associés à des moyens de commutation comportant quatre contacts (1 à D) manoeuvrés par un seul bouton de commande (non représenté) et un contact thermost tique E réglable manuellement. The various heating and ventilation elements used in this particular position are associated with switching means comprising four contacts (1 to D) operated by a single control button (not shown) and a thermostatic contact E manually adjustable.

L'ensemble de ce schéma électrique est branché aux bornes 40, 41 représentant une source de tension tel que le lecteur 220V par exemple. The whole of this electrical diagram is connected to terminals 40, 41 representing a voltage source such as the 220V reader for example.

4 contact A, connecté à la borne 40 permet la mise sous tension ou la coupure de l'enceinte de cuisson. 4 contact A, connected to terminal 40 enables the cooking chamber to be switched on or off.

Le moteur de turbine 8 est branché en série entre le contact A et en parallèle avec les différents éléments de chauffage de sole 20, 21. The turbine motor 8 is connected in series between the contact A and in parallel with the various hearth heating elements 20, 21.

Dans la position du dispositif de commutation selon l'invention, dans laquelle sont lis sous tension au moins un élément de chauffage de sole et la turbine de circulation d'air, il est bien entendu que toutes les combinaisons sont possibles, c'est-à-dire l'un ou l'autre des éléments de sole ou les deux, en parallèle avec la turbine. In the position of the switching device according to the invention, in which are read at least one hearth heating element and the air circulation turbine, it is understood that all combinations are possible, that is to say ie one or the other of the sole elements or both, in parallel with the turbine.

Noua nous contenterons de décrire un seul cas dans lequel les deux éléments de sole sont branchés en parallèle, la: turbine de circu- lation d'air étant branchée en parallèle sur l'ensemble. We will content ourselves with describing a single case in which the two floor elements are connected in parallel, the: air circulation turbine being connected in parallel to the assembly.

Tous les contacts A, B, C, D, E sont alors fermés et par exemple, la puissance de chauffe des éléments de sole est comprise entre 1400 W et 1700 W, et la puissance de la turbine de circulation d'air est je 35 W. All the contacts A, B, C, D, E are then closed and for example, the heating power of the hearth elements is between 1400 W and 1700 W, and the power of the air circulation turbine is je 35 W.

Sans sortir du cadre de l'invention, l'enceinte de cuisson peut par semple, autre un tour ou une cuisinière, et comporter tous les accessoires classiques d'une enceinte de cuisson conventionnelle et par exemple, une sonde de température, un éclairage du moufle et un catalyseur de rumées. Without departing from the scope of the invention, the cooking enclosure can for example, other a tower or a stove, and include all the conventional accessories of a conventional cooking enclosure and for example, a temperature probe, a lighting of the muffle and a rumor catalyst.
