Abstract
Description
La présente invention se rapporte à un dispositif de refroidissement de porte de four, en particulier de porte vitrée de four à usage ménager, comprenant un ventilateur de refroidissement. The present invention relates to a device for cooling an oven door, in particular a glass door for an oven for household use, comprising a cooling fan.
On connaît déjà des dispositifs du type précité (voir par exemple brevet suisse nO 633 413) ; en effet, dans les fours de cuisson des cuisines à usage ménager, il est désormais habituel d'utiliser des portes vitrées, pour permettre de suivre visuellement la cuisson des aliments placés dans le four ; il se pose donc le problème d'éviter que la vitre n'atteigne des températures trop élevées et par conséquent dangereuses en cas de contact accidentel avec la vitre. Devices of the aforementioned type are already known (see, for example, Swiss Patent No. 633,413); in fact, in cooking ovens for kitchens for household use, it is now customary to use glass doors, to allow visual monitoring of the cooking of food placed in the oven; the problem therefore arises of preventing the glass from reaching temperatures which are too high and therefore dangerous in the event of accidental contact with the glass.
A cet effet, il est connu d'utiliser des vitres doubles ou multiples, entre lesquelles se forment un ou plusieurs espaces intercalaires, de manière à réduire la transmission de la chaleur du four à la paroi de verre la plus extérieure. To this end, it is known to use double or multiple panes, between which one or more intermediate spaces are formed, so as to reduce the transmission of heat from the oven to the outermost glass wall.
Il est également connu d'insuffler de l'air dans l'un de ces espaces intercalaires à l'aide d'un ventilateur auxiliaire pour améliorer l'effet de refroidissement (voir par exemple la demande de brevet de la R.F.A. 30 14 908). It is also known to blow air into one of these intermediate spaces using an auxiliary fan to improve the cooling effect (see for example the patent application of FRG 30 14 908) .
Toutefois, la température atteinte par la vitre extérieure reste toujours élevée, de sorte qu'il est souhaitable de trouver un dispositif perfectionné qui la réduise encore, sans compliquer excessivement la structure ni accroître par conséquent excessivement le coût. However, the temperature reached by the outer pane always remains high, so it is desirable to find an improved device which further reduces it, without excessively complicating the structure nor consequently excessively increasing the cost.
Le but de la présente invention est de perfectionner le dispositif connu en enseignant la façon d'obtenir une amélioration du dispositif. The object of the present invention is to improve the known device by teaching how to obtain an improvement of the device.
Pour atteindre ce but, l'invention a pour objet un dispositif de refroidissement de porte de four, en particulier pour la porte vitrée d'un four à usage ménager comprenant un ventilateur de refroidissement, caractérisé en ce que la porte présente deux espaces interca laires, tous deux parcourus par des courants d'air de refroidissement. To achieve this object, the invention relates to a device for cooling an oven door, in particular for the glazed door of an oven for household use comprising a cooling fan, characterized in that the door has two intermediate spaces. , both traversed by cooling air currents.
Dans une version préférée de réalistion, l'invention prévoit que le flux d'air produit par le ventilateur est subdivisé en deux flux parallèles dont l'un est insufflé dans l'un desdits espaces intercalaires tandis que l'autre flux est utilisé pour créer une dépression dans la partie supérieure du deuxième espace intercalaire, de façon à y aspirer de l'air frais. In a preferred embodiment, the invention provides that the air flow produced by the fan is subdivided into two parallel flows, one of which is blown into one of said intermediate spaces while the other flow is used to create a depression in the upper part of the second intermediate space, so as to draw in fresh air.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de réalisation et en se reportant au dessin annexé donnez uniquement à titre d'exemple dont
la figure unique représente schématiquement un dispositif de refroidissement pour la porte vitrée d'un four à usage ménager selon l'invention.Other characteristics and advantages of the invention will be better understood on reading the description which follows of an exemplary embodiment and with reference to the appended drawing, give only by way of example,
the single figure schematically represents a cooling device for the glass door of a household oven according to the invention.
Sur le dessin, qui représente schématiquement en coupe un dispositif de refroidissement pour la porte vitrée d'un four à usage ménager selon l'invention, la référence 1 désigne un ventilateur de refroidissement, la référence 2 désigne la cavité du four de cuisson, la référence 3 désigne la vitre extérieure de la porte, la référence 4 désigne la vitre intermédiaire, et la réfé- rence 5 désigne la vitre intérieure. In the drawing, which schematically represents in section a cooling device for the glass door of a household oven according to the invention, the reference 1 designates a cooling fan, the reference 2 designates the cavity of the baking oven, the reference 3 designates the exterior window of the door, reference 4 designates the intermediate window, and reference 5 designates the interior window.
Les trois vitres 3, 4 et 5 délimitent deux espaces intercalaires, désignés respectivement par les références 6 (pour le plus intérieur) et 7 (pour le plus extérieur). The three panes 3, 4 and 5 delimit two intermediate spaces, designated respectively by the references 6 (for the most interior) and 7 (for the most exterior).
On a aussi indiqué par la référence 8 les ouvertures inférieures pour l'entrée d'air frais dans l'espace intercalaire 7 ; la référence 9 désigne une ouverture inférieure de sortie de l'air chaud de l'espace intercalaire 6. The lower openings for the entry of fresh air into the intermediate space 7 have also been indicated by the reference 8; the reference 9 designates a lower opening for the outlet of the hot air from the intermediate space 6.
On a indiqué par la référence 10 une ouverture supérieure de sortie d'air chaud de l'espace intercalai re 7 ; la référence 11 désigne un élément diffuseur, convenablement profilé, qui assure une subdivision du flux d'air produit par le ventilateur 1 en deux flux partiels, dont un flux inférieur, qui s'introduit dans l'espace intercalaire 6, en le refroidissant et en sortant ensuite par l'ouverture inférieure 9, et un flux supérieur, qui est convenablement guidé par la lèvre supérieure 12 de l'élément diffuseur Il (laquelle provoque une réduction de la section transversale du flux et par conséquent une augmentation de la vitesse de l'air) produit une dépression au droit du point 13, en créant par conséquent une efficace aspiration de l'air de l'espace 7. Reference 10 indicates an upper opening for the outlet of hot air from the intermediate space 7; the reference 11 designates a diffuser element, suitably profiled, which ensures a subdivision of the air flow produced by the fan 1 into two partial flows, including a lower flow, which is introduced into the intermediate space 6, cooling it and then leaving through the lower opening 9, and an upper flow, which is suitably guided by the upper lip 12 of the diffuser element II (which causes a reduction in the cross section of the flow and therefore an increase in the speed of air) produces a depression at point 13, thereby creating an efficient suction of air from space 7.
Les caractéristiques du dispositif de refroidissement selon l'invention ressortiront clairement de la description donnée ci-dessus ainsi que du dessin annexé, de même que les avantages en ressortent eux aussi clairement. en particulier, ces avantages consistent dans le fait qu'on obtient une double action de refroidissement, une première action sous l'effet du flux d'sir qui parcourt de haut en bas l'espace intercalaire le plus intérieur, et une deuxième action sous l'effet du flux d'air frais qui parcourt en sens inverse l'espace le plus extérieur, et qui est efficacement activé par l'effet d'aspiration obtenu grâce au deuxième flux partiel qui est ac célébré par l'élément profilé 11-12. The characteristics of the cooling device according to the invention will emerge clearly from the description given above as well as from the appended drawing, just as the advantages also emerge clearly from this. in particular, these advantages consist in the fact that a double cooling action is obtained, a first action under the effect of the flow of air which travels from top to bottom the most interior spacer space, and a second action under the effect of the flow of fresh air which traverses in the opposite direction the outermost space, and which is effectively activated by the suction effect obtained thanks to the second partial flow which is ac celebrated by the profiled element 11- 12.
Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit, sans sortir du cadre de l'invention. Of course, various modifications may be made by those skilled in the art to the device which has just been described, without departing from the scope of the invention.
