Description

La présente invention concerne un four présentant une ouverture entourée d'un joint et comprenant une porte de four elle-même munie d'une autre ouverture et d'au moins une vitre. De tels fours sont employés notamment dans l'industrie alimentaire, pour la pâtisserie par exemple.The present invention relates to an oven having an opening surrounded by a seal and comprising an oven door itself provided with another opening and at least one window. Such ovens are used in particular in the food industry, for pastry for example.

Les systèmes actuels de porte sur les fours comportent une vitre fixée au contact de la face interne de ladite porte, l'étanchéité de cette vitre étant faite à l'aide de joints, dits joints de vitre.Current door systems on ovens include a window fixed in contact with the internal face of said door, the sealing of this window being made using seals, called window seals.

L'étanchéité générale au niveau de la porte est assurée par des joints de porte fixés soit sur la porte et dirigés vers le four, soit sur le four et dirigés vers la porte.General sealing at the door is ensured by door seals fixed either on the door and directed towards the oven, or on the oven and directed towards the door.

Les problèmes inhérents à de tels systèmes sont des problèmes de fuite au niveau des joints de vitre, de commodité de nettoyage de ladite vitre et d'échauffement excessif de la porte.The problems inherent in such systems are problems of leakage at the level of the glass seals, of convenience of cleaning said glass and of excessive heating of the door.

On connaît par le document FR-A-2 201 440 une porte de four dans laquelle on a tenté de résoudre le problème de nettoyage de vitre en prévoyant une seconde vitre, démontable, du côé interne de la porte, mais cette solution complique la construction de la porte.Document FR-A-2 201 440 discloses an oven door in which an attempt has been made to solve the problem of cleaning glass by providing a second glass, removable, on the internal side of the door, but this solution complicates construction Door.

La présente invention se propose de pallier ces problèmes en présentant un nouveau dispositif de montage de la vitré sur la porte du four.The present invention proposes to overcome these problems by presenting a new device for mounting the glass on the oven door.

L'invention atteint son but grace au fait que la vitre est montée à une certaine distance de la face interne de la porte et est fixée à celle-ci. Le joint est fixé autour de l'ouverture du four et coopère avec la face interne de la vitre pour assurer, en position de fermeture de la porte, l'étanchéité du four.The invention achieves its object by virtue of the fact that the window pane is mounted at a certain distance from the internal face of the door and is fixed thereto. The seal is fixed around the opening of the oven and cooperates with the internal face of the glass to ensure, in the closed position of the door, the sealing of the oven.

Ainsi, la vitre selon l'invention est fixée sur la face interne de la porte du four, sans y être accolée, par l'intermédiaire d'entretoises et de tout moyen de fixation (vis, boulon....), et lui est de préférence parallèle. Ainsi n'y-t-il contact entre ces deux éléments (porte et vitre) que par l'intermédiaire de ces seules entretoises.Thus, the window according to the invention is fixed to the internal face of the oven door, without being attached thereto, by means of spacers and any fixing means (screws, bolts, etc.), and it is preferably parallel. Thus there is contact between these two elements (door and window) only through these only spacers.

Les entretoises sont situées par rapport à l'ouverture du four à l'intérieur ou de préférence à l'extérieur de ce joint assurant l'étanchéité et sur lequel la vitre s'appuie.The spacers are located relative to the opening of the oven inside or preferably outside of this seal ensuring the seal and on which the glass is supported.

Il résulte de ce montage selon l'invention, les avantages suivants;The following advantages result from this arrangement according to the invention;

Le nettoyage de la vitre est aisé car seule sa partie inteine, sans aspérité est à nettoyer.The cleaning of the window is easy because only its integral part, without roughness is to be cleaned.

Il n'y a plus à considérer des problèmes de fuite au niveau des joints de vitre, puisque de tels joints n'interviennent plus dans le montage selon l'invention.There are no longer any problems of leakage at the level of the glass seals, since such seals no longer occur in the assembly according to the invention.

De plus, un tel montage assure une meilleure isolation thermique de la porte du four. Une circulation d'air, par "effet cheminée" crée une certaine ventilation par convexion naturelle, entre la porte et la vitre. La propagation de la chaleur entre ces deux éléments est également sérieusement réduite puisqu'elle ne se fait que par l'intermédiaire des fixations ponctuelles.In addition, such an assembly provides better thermal insulation of the oven door. Air circulation, by "chimney effect" creates a certain ventilation by natural convection, between the door and the glass. The propagation of heat between these two elements is also seriously reduced since it only takes place through point fixings.

Les caractéristiques et avantages de l'invention seront mieux compris en se référant au dessin annexé.The characteristics and advantages of the invention will be better understood by referring to the attached drawing.

La figure 1 est une vue en coupe transversale d'un mode de réalisation d'une porte de four sur laquelle est montée une vitre suivant l'invention.Figure 1 is a cross-sectional view of an embodiment of an oven door on which is mounted a window according to the invention.

La figure 2 est une vue en coupe transversale d'un autre mode de réalisation d'une porte de four comportant deux vitres.Figure 2 is a cross-sectional view of another embodiment of an oven door having two panes.

A la figure 1 on a représenté en 1, l'ouverture du four, en 2, la vitre, en 3 la porte métallique de ce four, qui comporte elle même une ouverture 3'.In Figure 1 there is shown in 1, the opening of the oven, in 2, the glass, in 3 the metal door of this oven, which itself has an opening 3 '.

La vitre 2 est fixée sur la porte 3 grâce à quatre entretoises 4, aux quatre coins de la porte. La fermeture du four est réalisée grâce à l'appui de ladite vitre 2 sur le joint 5 qui est de préférence fixé autour de l'ouverture 1 du four.The window 2 is fixed to the door 3 by means of four spacers 4, at the four corners of the door. The oven is closed by pressing said window 2 on the seal 5 which is preferably fixed around the opening 1 of the oven.

Les entretoises 4 à l'intérieur desquelles on a ménagé un passage utilisé pour solidariser ladite vitre 2 avec ladite porte 3 par un dispositif à vis ou ou boullon 4', sont à l'extérieur du joint 5 par rapport à l'ouverture du four. Toutefois les entretoises 4 peuvent être situées à l'intérieur du joint 5 par rapport à l'ouverture du four.The spacers 4 inside which a passage has been provided, used to secure said window 2 with said door 3 by a screw or bolt device 4 ′, are outside the seal 5 relative to the opening of the oven . However, the spacers 4 can be located inside the seal 5 relative to the opening of the oven.

La circulation d'air entre la porte et la vitre est symbolisée par les deux grandes flèches.The air circulation between the door and the glass is symbolized by the two large arrows.

A la figure 2 on a représenté une porte 3, sur laquelle est fixée une première vitre 6 avec interposition d'une entretoise 7 entre la vitre et la face interne de la porte. Une seconde vitre 2 est fixée sur les vis 4' solidraires de la porte avec interposition d'entretoises 4 à une certaine distance de la face interne de la porte 3 et de la première vitre 6. La seconde vitre 2 coopère avec un joint 5 entourant l'ouverture du four 1 pour assurer la fermeture de celui-ci.In Figure 2 there is shown a door 3, on which is fixed a first window 6 with interposition of a spacer 7 between the window and the inner face of the door. A second window 2 is fixed to the screws 4 'integral with the door with the interposition of spacers 4 at a certain distance from the internal face of the door 3 and from the first window 6. The second window 2 cooperates with a surrounding seal 5 the opening of the oven 1 to ensure the closing thereof.

La première vitre 6 est fixée à proximité ou contre la face interne de la porte.The first window 6 is fixed near or against the internal face of the door.

Comme dans le mode de réalisation de la figure 1 une circulation d'air s'établit entre les vitres 2 et 6.As in the embodiment of FIG. 1, an air circulation is established between the panes 2 and 6.
