Abstract

The light is incorporated in the thickness of the oven door. The door is double skinned and has a central viewing window, the inner skin having an opening covered by a glass plate aligned with the light bulb, to allow the light to be directed into the oven interior. Pref. two light bulbs are used positioned at diametrically opposed corners of the glass window, so that the light shines into the oven interior when the door is closed at two different levels. The socket for each bulb is pref. attached to a heat insulating sheet between the two spaced door skins with the supply lead fitting through an opening in the hinged edge of the door. The light provides better viewing of the oven contents by positioning the light source between the oven interior and the observer instead of at the back of the oven.

Description

La présente invention a pour objet un dispositif d'éclairage pour four de cuisinière à usage domestique. The present invention relates to a lighting device for a stove oven for domestic use.

Les fours de cuisinières qu'ils soient chauffés au gaz ou à ltélectricité comportent une porte fermant avec étanchéité permettant le chargement et le déchargement. Le plus souvent, la porte présente une ouverture centrale obturée par au moins une vitre transparente permettant la vision des produits en période de cuisson. The range ovens, whether heated with gas or electricity, have a closing door with sealing allowing loading and unloading. Most often, the door has a central opening closed by at least one transparent window allowing the vision of the products during the cooking period.

Compte tenu du fait que l'ouverture est relativement petite, et que la ou les vitres obturant celle-ci sont fréquemment teintées, l'intérieur du four est très mal éclairé à partir de l'extérieur. Il est donc prévu habituellement un dispositif d'éclairage spécifique de l'intérieur du four par l'intermédiaire d'une ampoule logée à l'extérieur de l'enceinte de celui-ci et diffusant la lumière par une ouverture que présente celle-ci qui est obturée par une vitre transparente ou translucide. Given the fact that the opening is relatively small, and that the window or windows closing the latter are frequently tinted, the interior of the oven is very poorly lit from the outside. There is therefore usually provided a specific lighting device for the interior of the furnace by means of a bulb housed outside the enclosure thereof and diffusing the light through an opening which the latter presents. which is closed by a transparent or translucent window.

Dans les fours à pyrolyse, l'ampoule est logée à la partie postérieure du four, étant donné que, pour des raisons techniques, il n'est pas possible de placer celle-ci à la partie supérieure, qui est occupée par des organes d'aération. Dans le cas de fours à catalyse, l'ampoule est logée soit dans la paroi postérieure, soit dans la paroi supérieure. In pyrolysis ovens, the bulb is housed at the rear part of the oven, since, for technical reasons, it is not possible to place it at the upper part, which is occupied by organs of 'aeration. In the case of catalysis ovens, the bulb is housed either in the rear wall or in the upper wall.

Dans tous les cas, l'éclairage est relativement peu efficace car très éblouissant pour l'utilisateur, le produit à voir se trouvant entre la source lumineuse et l'oeil.  In all cases, the lighting is relatively ineffective because it is very dazzling for the user, the product to be seen being between the light source and the eye.

En outre, si plusieurs produits disposés de manière superposée cuisent simultanément dans le four, seul l'un d'entre eux, à savoir celui situé en partie haute, sera éclairé, les autres se trouvant dans
La présente invention vise à remédier à ces inconvénients.
In addition, if several superimposed products cook simultaneously in the oven, only one of them, namely the one located in the upper part, will be lit, the others being in
The present invention aims to remedy these drawbacks.

A cet effet, le dispositif d'éclairage qu'elle concerne comprend au moins une ampoule logée dans ltépais- seur de la porte et diffusant de la lumière dans le four par une ouverture que présente la contre-porte. To this end, the lighting device which it relates comprises at least one bulb housed in the thickness of the door and diffusing light into the oven through an opening which the door has.

Cette solution est très intéressante car la source lumineuse étant située entre l'oeil de l'utilisateur et le produit que contient le four, n'entraîne aucun éblouisse- ment. En outre, d'un-point de vue technique, il faut noter que la porte est la zone la plus froide du four et que, dans ces conditions, l'installation d'éclairage ne souffre pas de la température. This solution is very interesting because the light source being located between the eye of the user and the product contained in the oven, does not cause any glare. In addition, from a technical point of view, it should be noted that the door is the coldest area of the oven and that, under these conditions, the lighting installation does not suffer from the temperature.

Avantageusement, ce dispositif comprend deux ampoules logées dans les deux montants délimitant latéralement 1'ouverture centrale de la porte du four, ces deux ampoules étant décalées verticalement quand la porte est en position fermée. Advantageously, this device comprises two bulbs housed in the two uprights laterally delimiting the central opening of the oven door, these two bulbs being offset vertically when the door is in the closed position.

Cet agencement assure un éclairage à des niveaux différents du four, ce qu permet une bonne vision simultanée de plusieurs produits superposés dans le four. This arrangement provides lighting at different levels of the oven, which allows good simultaneous vision of several products stacked in the oven.

Selon une caractéristique de l'invention, pour chaque ampoule est prévu un logement ménagé dans le calorifuge entre la contre-porte et la tôle de calorifuge, la douille portant l'ampoule et assurant son alimentation en courant électrique étant fixée sur la tôle de calorifuge. According to a characteristic of the invention, for each bulb is provided a housing formed in the insulation between the door and the heat-insulating sheet, the socket carrying the bulb and ensuring its supply of electric current being fixed on the heat-insulating sheet .

Cet agencement permet de réaliser un montage invisible de l'ampoule puisque la fixation est réalisée sur la tôle de calorifuge qui est masquée en position montée de la porte. Afin d'assurer un bon aspect de fini et protéger l'ampoule, l'ouverture que comporte la contre-porte en regard de celle-ci, est obturée par une vitre. This arrangement allows an invisible mounting of the bulb to be carried out since the fixing is carried out on the heat-insulating sheet which is hidden in the mounted position of the door. In order to ensure a good finish appearance and protect the bulb, the opening that the storm door has opposite it is closed by a window.

En outre, l'alimentation en courant électrique des ampoules est réalisée par un fil pénétrant dans la porte dans la zone inférieure de celle-ci située à proximité de son axe d'articulation. In addition, the electric current is supplied to the bulbs by a wire penetrating into the door in the lower zone thereof, located near its axis of articulation.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution d'un four équipé de ce dispositif d'éclairage :
Figure 1 est une vue en perspective d'une cuisinière, la porte du four étant en position ouverte
Figure 2 est une vue en coupe et à échelle agrandie de la porte selon la ligne 2-2 de figure 1.
In any case, the invention will be better understood with the aid of the description which follows with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of an oven equipped with this device. lighting :
Figure 1 is a perspective view of a stove, the oven door being in the open position
Figure 2 is a sectional view on an enlarged scale of the door along line 2-2 of Figure 1.

La cuisinière 2 représentée au dessin comporte un four désigné par la référence générale 2, obturE par une porte 4. The cooker 2 shown in the drawing comprises an oven designated by the general reference 2, closed by a door 4.

Laporte de ce four comprend une contre-porte 5 et une tôle de calorifuge 6, un matériau isolant thermique non représente au dessin ôtant logé à l'intérieur du du volume compris entre ces deux éléments. The door of this oven comprises a door 5 and a heat-insulating sheet 6, a thermal insulating material not shown in the drawing being removed housed inside the volume between these two elements.

Ce volume est de forme générale annulaire, une ouverture centrale 7 ôtant ménagée dans la porte. Cette ouverture est obturée par deux vitres 8, une vitre extérieure 9 recouvrant la presque totalité de la face avant de la porte avec ménagement d'une lame d'air dynamique 10 de refroidissement entre la porte proprement dite et la vitre exterieure 9. This volume is generally annular in shape, a central opening 7 being removed from the door. This opening is closed by two panes 8, an outer pane 9 covering almost the entire front face of the door, with a dynamic air space 10 for cooling between the door proper and the outer pane 9.

Cette porte est articulée à sa partie inférieure autour d'un axe horizontal 12, une poignée 13^placée à proximité de son bord supérieur permettant son actionnement. This door is articulated at its lower part about a horizontal axis 12, a handle 13 ^ placed near its upper edge allowing its actuation.

Selon la caractéristique essentielle de l'invention, le dispositif d'éclairage du four est logé à l'intérieur de la porte. Dans le cas présent, cette porte présente deux dispositifs d'éclairage logés dans les montants latéraux situés de part et d'autre de l'ouverture centrale, et sont décalés de manière à se trouver à des niveaux différents lorsque la porte est en position fermée. According to the essential characteristic of the invention, the oven lighting device is housed inside the door. In this case, this door has two lighting devices housed in the lateral uprights located on either side of the central opening, and are offset so as to be at different levels when the door is in the closed position. .

Chaque dispositif comprend une douille 14 fixée en 15 et 16 sur la tôle de calorifuge, portant une ampoule vissée a incandescence 17. L'alimentation en courant est réalisée par l'intermédiaire d'un fil 18 pénétrant dans la porte par une ouverture 19 ménagée dans le bord inférieur de celle-ci. Each device comprises a socket 14 fixed at 15 and 16 on the heat-insulating sheet, carrying a screwed incandescent bulb 17. The power supply is carried out by means of a wire 18 penetrating into the door through an opening 19 provided in the lower edge of it.

La contre-porte 5 présente, en regard de l'ampoule 17, une ouverture 20 obturée par un verre 22 qui peut être translucide et jouer un rôle de diffuseur. Against the door 5 has, opposite the bulb 17, an opening 20 closed by a glass 22 which can be translucent and play the role of a diffuser.

Comme il ressort de ce qui précède7 le dispositif selon l'invention apporte une grande amélioration à latechnique existante en réalisant l'éclairage d'un four de manière simple techniquement, tout en étant très-pratique pour l'utilisateur. As is clear from the foregoing, the device according to the invention brings a great improvement to the existing technique by providing the lighting of an oven in a technically simple manner, while being very practical for the user.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce four, décrite ci-dessus à titre d'exemple ; elle en embrasse, au contraire, toutes les variantes de réalisation. It goes without saying that the invention is not limited to the sole embodiment of this oven, described above by way of example; on the contrary, it embraces all of its variant embodiments.

C'est ainsi notamment que l'éclairage pourrait entre réalisé non pas par des ampoules à incandescence,mais par des tubes fluorescents sans que l'on sorte pour autant du cadre de l'intention. Thus, in particular, the lighting could be achieved not by incandescent bulbs, but by fluorescent tubes without departing from the framework of the intention.
