Description

La présente invention concerne un four de cuisson à usage domestique comprenant und enceinte de cuisson, une résistance de chauffage électrique, et un ventilateur pour créer une circulation d'air à l'intérieur de l'enceinte.The present invention relates to a cooking oven for domestic use comprising a cooking enclosure, an electric heating resistor, and a fan for creating an air circulation inside the enclosure.

Certains fours de cuisson dits à chaleur tournante comportent en leur intérieur généralement près de la face arrière de l'enceinte de cuisson, un ventilateur qui permet de brasser l'air à l'intérieur de cette enceinte.Certain so-called fan-assisted cooking ovens have inside a fan generally near the rear face of the cooking chamber, a fan which makes it possible to stir the air inside this chamber.

L'enceinte de cuisson comporte bien entendu également des résistances électriques de chauffage et une sonde thermique reliée à un organe de régulation de la température.The cooking chamber naturally also includes electrical heating resistors and a thermal probe connected to a temperature regulation member.

La présence du ventilateur, des résistances et de la sonde thermique à l'intérieur de l'enceinte de cuisson rend cedlle-ci difficilement nettoyable.The presence of the fan, the resistors and the thermal probe inside the cooking chamber makes it difficult to clean.

De plus, la construction de tels fours est rendue complexe et onéreuse par le fait qu'il est nécessaire de prévoir à l'intérieur de l'enceinte de cuisson des moyens pour fixer les résistances, le ventilateur, la sonde thermique et divers passages notamment pour l'alimentation électrique des résistances. Par ailleurs, la disposition des résistances par rapport au flux d'air engendré par la ventilation n'est généralement pas optimale.In addition, the construction of such ovens is made complex and expensive by the fact that it is necessary to provide inside the cooking chamber means for fixing the resistors, the fan, the thermal probe and various passages in particular. for the power supply of the resistors. Furthermore, the arrangement of the resistors with respect to the air flow generated by the ventilation is generally not optimal.

Le but de la présente invention est de remédier aux inconvénients des réalisations connues en créant un four de cuisson de construction simple, dont l'intérieur est facilement nettoyable et dans lequel la disposition des résistances par rapport au flux d'air est optimale.The object of the present invention is to remedy the drawbacks of known embodiments by creating a cooking oven of simple construction, the interior of which is easily cleaned and in which the arrangement of the resistances with respect to the air flow is optimal.

L'invention vise ainsi un four de cuisson, notamment à usage domestique, comprenant une enceinte de cuisson intérieure et une carrosserie extérieure, la face avant étant munie d'une porte d'accès et la face arrière comportant une paroi de fond amovible.The invention thus relates to a cooking oven, in particular for domestic use, comprising an interior cooking enclosure and an exterior bodywork, the front face being provided with an access door and the rear face comprising a removable bottom wall.

Suivant l'invention, ce four est caractérisé en ce que ladite paroi de fond est associée à un caisson dans lequel sont montés un ventilateur entraîné par un moteur, une résistance de chauffage électrique et des moyens de régulation du chauffage de cette dernière, la résistance de chauffage étant placée dans le flux d'air engendré par le ventilateur et la paroi de fond comportant des ouvertures de passage du flux d'air.According to the invention, this oven is characterized in that said bottom wall is associated with a box in which are mounted a fan driven by a motor, an electric heating resistor and means for regulating the heating of the latter, the heating resistor being placed in the air flow generated by the fan and the bottom wall having openings for passage of the air flow.

Ainsi, les organes essentiels de chauffage et de ventilation du four sont regroupés dans un caisson qui est extérieur au four. De ce fait, l'intérieur de l'enceinte de cuisson est dépourvu de tout organe susceptible de compliquer la construction et le nettoyage du four.Thus, the essential heating and ventilation elements of the oven are grouped in a box which is outside the oven. Therefore, the interior of the cooking chamber is devoid of any member capable of complicating the construction and cleaning of the oven.

En effet, le fait d'avoir regroupé tous ces organes dans un caisson extérieur à l'enceinte de cuisson facilite considérablement le montage du four de cuisson.Indeed, the fact of having grouped all these organs in a box outside the cooking chamber considerably facilitates the mounting of the cooking oven.

Par ailleurs, le fait que la résistance de chauffage soit placée dans le flux d'air engendré par le ventilateur permet une production d'air chaud dans des conditions thermiques très favorables, tout en garantissant un brassage optimal de l'air à l'intérieur de l'enceinte de cuisson.Furthermore, the fact that the heating resistor is placed in the air flow generated by the fan allows production of hot air under very favorable thermal conditions, while guaranteeing optimal mixing of the air inside. of the cooking chamber.

Ainsi, le four conforme à l'invention diffère du four classique statique, par le fait que sa paroi de fond fermée est remplacée par un sous-ensemble, comprenant une paroi de fond à ouvertures recouverte par un caisson à l'intérieur duquel sont montés tous les organes nécessaires pour transformer le four classique en un four ventilé.Thus, the oven according to the invention differs from the conventional static oven, in that its closed bottom wall is replaced by a sub-assembly, comprising a bottom wall with openings covered by a box inside which are mounted. all the components necessary to transform the conventional oven into a ventilated oven.

Le sous-ensemble, précité constitue ainsi une sorte de kit de montage qui permet de transformer un four classique en four ventilé. Cette transformation est aisée du fait que les moyens de fixation prévus pour la paroi de fond du four classique peuvent servir pour fixer le sous-ensemble précité, que se substitue ainsi à la paroi ci-dessus.The aforementioned sub-assembly thus constitutes a sort of mounting kit which makes it possible to transform a conventional oven into a ventilated oven. This transformation is easy because the fixing means provided for the bottom wall of the conventional oven can be used to fix the aforementioned sub-assembly, which thus replaces the above wall.

Selon une version préférée de l'invention, le ventilateur est monté en rotation suivant un axe perpendiculaire à la paroi muni d'ouvertures, le ventilateur comporte des pales engendrant un flux d'air radial et la résistance de chauffage entoure le ventilateur.According to a preferred version of the invention, the fan is mounted in rotation along an axis perpendicular to the wall provided with openings, the fan comprises blades generating a radial air flow and the heating resistance surrounds the fan.

Ainsi, la résistance de chauffage se trouve directement dans le flux d'air radial engendré lors de la rotation du ventilateur.Thus, the heating resistance is located directly in the radial air flow generated during the fan rotation.

De préférence, la résistance de chauffage comprend une ou plusieurs spires entourant le ventilateur. Cette disposition permet de réaliser un échange thermique optimal entre le flux d'air et la résistance de chauffage.Preferably, the heating resistor comprises one or more turns surrounding the fan. This arrangement allows optimal heat exchange between the air flow and the heating resistor.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

Dans la réalisation des figures annexées, le four de cuisson notamment à usage domestique comprend une enceinte de cuisson 1 intérieure de forme générale parallélépipédique entourée par une carrosserie extérieure.In the embodiment of the appended figures, the cooking oven in particular for domestic use comprises an interior cooking enclosure 1 of generally parallelepipedal shape surrounded by an exterior bodywork.

La face avant est munie d'une porte d'accès (non représentée) et la face arrière comporte une paroi de fond amovible 2. Cette paroi de fond 2 est associée à un caisson 3 s'appuyant sur sa périphérie dans lequel sont montés un ventilateur 4 entraîné par un moteur 9, une résistance de chauffage éléctrique 5 et des moyens 15 de régulation du chauffage de cette dernière. La résistance de chauffage 5 est placée dans le flux d'air engendré par le ventilateur et la paroi de fond 2 comporte des ouvertures 6, 7, 8 de passage du flux d'air.The front face is provided with an access door (not shown) and the rear face has a removable bottom wall 2. This bottom wall 2 is associated with a box 3 resting on its periphery in which are mounted a fan 4 driven by a motor 9, an electric heating resistor 5 and means 15 for regulating the heating of the latter. The heating resistor 5 is placed in the air flow generated by the fan and the bottom wall 2 has openings 6, 7, 8 for passage of the air flow.

Dans la réalisation représentée, le caisson 3 comporte un rebord périphérique 3a qui est fixé au moyen de vis au bord de la paroi arrière 2 du four. Ces vis servent à fixer en même temps la paroi de fond 2 et le caisson 3 contre la périphérie de la carrosserie du four.In the embodiment shown, the box 3 has a peripheral rim 3a which is fixed by means of screws to the edge of the rear wall 2 of the oven. These screws are used to fix the bottom wall 2 and the box 3 at the same time against the periphery of the furnace body.

Le caisson 3 supporte le moteur 9 d'entraînement en rotation du ventilateur 4 et contient les moyens de régulation du chauffage de la résistance 5.The box 3 supports the motor 9 for driving the fan 4 in rotation and contains the means for regulating the heating of the resistor 5.

Ce moteur 9 comporte un arbre 10 (voir figure 4) qui traverse la paroi du caisson 3 et porte le ventilateur 4.This motor 9 comprises a shaft 10 (see FIG. 4) which passes through the wall of the box 3 and carries the fan 4.

Le ventilateur 4 est ainsi monté en rotation suivant un axe perpendiculaire à la paroi 2 munies des ouvertures 6, 7, 8.The fan 4 is thus mounted in rotation along an axis perpendicular to the wall 2 provided with the openings 6, 7, 8.

Par ailleurs, on voit sur les figures 2 et 4 que le ventilateur 4 comporte des pales engendrant un flux d'air radial et la résistance de chauffage 5 entoure le ventilateur 4.Furthermore, it can be seen in FIGS. 2 and 4 that the fan 4 has blades generating a radial air flow and the heating resistor 5 surrounds the fan 4.

Dans l'exemple représenté, cette résistance de chauffage 5 comprend deux spires qui entourent le ventilateur 4. Cette résistance 5 est fixée au fond du caisson 3 au moyen des pattes 11, 12.In the example shown, this heating resistor 5 comprises two turns which surround the fan 4. This resistor 5 is fixed to the bottom of the box 3 by means of the tabs 11, 12.

On voit sur la figure 3 que la paroi 2 de l'enceinte de cuisson adjacente au ventilateur 4 comprend une série d'ouvertures 6 disposées en regard de la partie centrale du ventilateur et des ouvertures latérales 7, 8 disposées en regard de la périphérie de ce dernier.It can be seen in FIG. 3 that the wall 2 of the cooking enclosure adjacent to the fan 4 comprises a series of openings 6 arranged facing the central part of the fan and lateral openings 7, 8 arranged facing the periphery of this last.

Ces ouvertures latérales 7, 8 en forme de fentes, comportent chacune sur leur bond extérieur un volet 7a, 8a incliné vers la résistance 5 (voir figure 4).These lateral openings 7, 8 in the form of slots, each have on their outer bond a flap 7a, 8a inclined towards the resistor 5 (see FIG. 4).

Sur les figures 2 et 4, on voit également que le moteur électrique 9 situé à l'extérieur du caisson métallique 3 est entouré par un boîtier 13 muni d'une grille 14 d'aération pour refroidir le moteur 9.In FIGS. 2 and 4, it can also be seen that the electric motor 9 located outside the metal box 3 is surrounded by a box 13 provided with a ventilation grid 14 for cooling the motor 9.

Le caisson 3 renferme en outre (voir figures 2 et 4) une sonde thermique 15 reliée à un thermostat non représenté servant à réguler la température de chauffage.The box 3 also contains (see FIGS. 2 and 4) a thermal probe 15 connected to a thermostat, not shown, used to regulate the heating temperature.

A l'emplacement référencé 16 du caisson 3 (voir figure 2), on peut également disposer une lampe électrique pour éclairer l'intérieur de l'enceinte de cuisson à travers une ouverture pratiquée à l'emplacement 17 (voir figure 3) de la face arrière 2 de l'enceinte de cuisson. Tous les organes de chauffage, de ventilation, de régulation et d'éclairage du four sont ainsi regroupés à l'extérieur de l'enceinte de cuisson 1. L'intérieur de cette enceinte de cuisson 1 est de ce fait dépourvu de tous ces organes et est ainsi de construction très simple et facilement nettoyable.At the location referenced 16 of the box 3 (see FIG. 2), an electric lamp can also be placed to light the interior of the cooking enclosure through an opening made in location 17 (see FIG. 3) of the rear side 2 of the cooking chamber. All the heating, ventilating, regulating and lighting components of the oven are thus grouped outside the cooking enclosure 1. The interior of this cooking enclosure 1 is therefore devoid of all these organs and is thus very simple and easily cleaned.

Le fonctionnement du four de cuisson que l'on vient de décrire est le suivant :The operation of the cooking oven that has just been described is as follows:

Lors de la rotation du ventilateur 4, l'air de l'enceinte de cuisson 1 est aspiré vers le ventilateur à travers les ouvertures centrales 6 (voir flèches F sur la figure 4).When the fan 4 rotates, the air from the cooking chamber 1 is drawn towards the fan through the central openings 6 (see arrows F in FIG. 4).

L'air est ensuite propulsé radialement par le ventilateur 4 vers les spires de la résistance de chauffage 5 qui ont ainsi pour effet de réchauffer cet air. L'air chaud ainsi formé est propulsé par le ventilateur à l'intérieur de l'enceinte de cuisson 1 par les fentes latérales 7, 8. Les volets 7a, 8a de celles-ci agissent comme déflecteurs pour faciliter l'entrée de l'air chaud à l'intérieur de l'enceinte de cuisson 1 (voir flèches F₁).The air is then propelled radially by the fan 4 towards the turns of the heating resistor 5 which thus have the effect of heating this air. The hot air thus formed is propelled by the fan inside the cooking chamber 1 by the side slots 7, 8. The flaps 7a, 8a thereof act as deflectors to facilitate the entry of the hot air inside the cooking chamber 1 (see arrows F₁).

Ainsi, grâce à l'invention, il est possible de transformer très facilement un four classique en un four ventilé. A cet effet, il suffit de remplacer la paroi de fond fermée du four classique par la paroi ajourée 2 sur laquelle s'appuie le rebord périphérique du caisson 3 qui renferme tous les organes de ventilation et de chauffage. Cette transformation est d'autant plus facile que l'on peut utiliser à cet effet les trous de fixation normalement prévus pour fixer la paroi du found du four classique.Thus, thanks to the invention, it is possible to very easily transform a conventional oven into a ventilated oven. To this end, it suffices to replace the closed bottom wall of the conventional oven with the perforated wall 2 on which the peripheral rim of the box 3 rests, which contains all the ventilation and heating elements. This transformation is all the easier since the fixing holes normally provided for fixing the wall of the base of the conventional oven can be used for this purpose.

Ainsi, le fabricant d'un four classique peut utiliser l'enceinte de cuisson entourée par le carrosserie de ce four classique, pour le transformer en un four ventilé en remplaçant la paroi de fond par le sous-ensemble de ventilation précité, sans avoir à équiper l'intérieur de l'enceinte de cuisson des résistances de chauffage qui grèvent le coût de fabrication des fours classiques.Thus, the manufacturer of a conventional oven can use the cooking enclosure surrounded by the body of this conventional oven, to transform it into a ventilated oven by replacing the bottom wall with the aforementioned ventilation sub-assembly, without having to equipping the interior of the cooking chamber with heating resistors which add to the cost of manufacturing conventional ovens.
