Description

APPAREIL DE CUISSON EQUIPE D’UN BOÎTIER EXTERNE DE COOKING APPLIANCE WITH AN EXTERNAL HOUSING
RACCORDEMENT DU CORDON D’ALIMENTATION ELECTRIQUE ELECTRICAL CORD CONNECTION
Domaine technique Technical area
La présente invention concerne les appareils de cuisson qui sont alimentés électriquement par l’intermédiaire d’un cordon d’alimentation électrique. The present invention relates to cooking appliances which are supplied electrically by means of an electrical supply cord.
Un objectif principal est de réduire les échauffements de l’extrémité du cordon d’alimentation électrique qui est connectée à un circuit d’alimentation électrique des différents organes électriques de l’appareil de cuisson, par exemple un système de chauffe, un système de commande et un système de ventilation. A main objective is to reduce overheating of the end of the electrical supply cord which is connected to an electrical supply circuit of the various electrical components of the cooking appliance, for example a heating system, a control system and a ventilation system.
Etat de la technique State of the art
Traditionnellement, les appareils de cuisson comprennent une coque incorporant un système de chauffe agencé à l’intérieur de la coque et alimenté par un circuit d’alimentation électrique, lequel est connecté à un cordon d’alimentation électrique et une enceinte de cuisson agencée à l’intérieur de la coque. Le cordon d’alimentation électrique est branché sur le secteur soit au moyen d’une prise mâle embrochée dans une prise femelle complémentaire, soit au moyen d’une sortie de câble. Traditionally, cooking appliances include a shell incorporating a heating system arranged inside the shell and powered by an electrical power circuit, which is connected to an electrical power cord and a cooking enclosure arranged at the inside the hull. The power supply cord is connected to the mains either by means of a male plug plugged into a complementary female socket, or by means of a cable outlet.
La température de la zone de connexion électrique entre l’extrémité du cordon d’alimentation électrique et le circuit d’alimentation électrique de l’appareil de cuisson est réglementée, celle-ci ne devant pas dépasser un certain seuil défini. En particulier, la normalisation actuelle IEC 60 335 impose de ne pas avoir un échauffement de l’extrémité du cordon d’alimentation électrique de plus de soixante-cinq degrés Celsius (65°C). Ce seuil de température peut être rapidement atteint sur certains appareils de cuisson, par exemple sur les friteuses et, plus particulièrement, sur les friteuses à air chaud utilisant peu d’huile pour la cuisson, voire pas du tout d’huile. C’est ainsi que sur certaines friteuses à air chaud, la coque est équipée d’un caisson isolé agencé sous l’enceinte de cuisson, un bornier de raccordement agencé dans le caisson assurant la connexion entre l’extrémité du cordon d’alimentation électrique et le circuit d’alimentation électrique. Le caisson permet en outre le rangement du cordon électrique à l’intérieur de celui-ci, lorsque la friteuse à air chaud n’est pas utilisée. The temperature of the electrical connection area between the end of the electrical supply cord and the electrical supply circuit of the cooking appliance is regulated, the latter must not exceed a certain defined threshold. In particular, the current standardization IEC 60 335 imposes not to have a heating of the end of the electric power cord of more than sixty-five degrees Celsius (65 ° C). This temperature threshold can be quickly reached on certain cooking appliances, for example on fryers and, more particularly, on hot air fryers using little or no oil for cooking. Thus, on certain hot air fryers, the shell is equipped with an insulated box arranged under the cooking chamber, a connection terminal block arranged in the box ensuring the connection between the end of the electrical supply cord. and the power supply circuit. The box also allows the storage of the electric cord inside of it, when the hot air fryer is not used.
Cette conception présente pour inconvénients de rehausser considérablement la friteuse à air chaud et d’augmenter son volume. En outre, l’atténuation de la température au niveau de l’extrémité du cordon d’alimentation électrique n’est pas optimale. This design has the drawbacks of considerably raising the hot air fryer and increasing its volume. In addition, the temperature reduction at the end of the power cord is not optimal.
Résumé de l’invention Summary of the invention
La présente invention pallie les inconvénients précités. Elle a également pour avantage de permettre sa mise en œuvre sur tout type d’appareil de cuisson. The present invention overcomes the aforementioned drawbacks. It also has the advantage of allowing its implementation on any type of cooking appliance.
A cette effet, l’invention concerne un appareil de cuisson qui comprend une coque munie d’un contour et incorporant un système de chauffe agencé à l’intérieur de la coque et alimenté par un circuit d’alimentation électrique connecté à un cordon d’alimentation électrique et une enceinte de cuisson agencée à l’intérieur de la coque. Selon le type d’appareil de cuisson mis en œuvre, celui-ci peut également comprendre un système de ventilation et un système de commande. To this end, the invention relates to a cooking appliance which comprises a shell provided with a contour and incorporating a heating system arranged inside the shell and supplied by an electrical supply circuit connected to a power cord. power supply and a cooking enclosure arranged inside the shell. Depending on the type of cooking appliance used, it can also include a ventilation system and a control system.
Selon l’invention, l’appareil de cuisson comprend un boîtier externe agencé sur une paroi du contour de la coque et un bornier de raccordement logé dans le boîtier externe et assurant la connexion électrique entre le circuit d’alimentation électrique et le cordon d’alimentation électrique. According to the invention, the cooking appliance comprises an external box arranged on a wall of the contour of the shell and a connection terminal block housed in the external box and ensuring the electrical connection between the electrical supply circuit and the cord. power supply.
Ces caractéristiques de l’appareil de cuisson selon l’invention permettent de déporter en dehors de la coque la connexion électrique entre le circuit d’alimentation électrique et l’extrémité du cordon d’alimentation électrique, c’est-à-dire en dehors de la zone soumise à des échauffements importants lors de l’activation du système de chauffe. These characteristics of the cooking appliance according to the invention make it possible to offset the electrical connection between the circuit outside the hull. power supply and the end of the power supply cord, that is to say outside the area subject to significant heating during the activation of the heating system.
Selon un aspect de l’invention, la coque incorpore un système de commande destiné à commander le système de chauffe. According to one aspect of the invention, the shell incorporates a control system for controlling the heating system.
Selon une réalisation de l’appareil de cuisson, le boîtier externe comprend une zone de logement du bornier de raccordement et une chambre d’isolation agencée dans le boîtier externe pour séparer la zone de logement, de la paroi du contour de la coque. Cela permet d’obtenir une meilleure isolation thermique du bornier de raccordement qui se situe dans la zone de logement, à distance de la coque qui chauffe lors de l’activation du système de chauffe. According to one embodiment of the cooking appliance, the external housing comprises a housing area for the connection terminal block and an isolation chamber arranged in the external housing to separate the housing zone from the wall of the outline of the shell. This allows better thermal insulation of the connection terminal block which is located in the housing area, away from the shell which heats up when the heating system is activated.
Afin d’optimiser encore cette isolation thermique du bornier de raccordement, le boîtier externe comprend préférentiellement des ouïes d’aération qui débouchent dans la chambre d’isolation pour la ventiler naturellement. In order to further optimize this thermal insulation of the connection terminal block, the external housing preferably includes ventilation openings which open into the isolation chamber to ventilate it naturally.
Selon une réalisation de l’appareil de cuisson objet de l’invention, outre les caractéristiques précitées, le boîtier externe est agencé pour former un range- câble permettant l’enroulement du cordon d’alimentation électrique. En d’autres termes, la forme du boîtier externe et son positionnement sur la paroi du contour de la coque sont mis en œuvre pour permettre un enroulement du cordon d’alimentation électrique sur ledit boîtier externe ou autour de celui-ci, à la manière d’un range-câble. Selon une mise en œuvre préférentielle, le boîtier externe comprend un corps autour duquel s’enroule le cordon d’alimentation électrique, le corps s’étendant perpendiculairement à la paroi du contour de la coque, et deux branches s’étendant en opposition à une extrémité du corps pour maintenir le cordon d’alimentation électrique enroulé autour du corps. According to an embodiment of the cooking appliance which is the subject of the invention, in addition to the aforementioned characteristics, the external housing is arranged to form a cable holder allowing the winding of the electrical supply cord. In other words, the shape of the external housing and its positioning on the wall of the contour of the shell are implemented to allow winding of the power supply cord on or around said external housing, in the manner a cable holder. According to a preferred implementation, the external housing comprises a body around which the electrical supply cord is wound, the body extending perpendicular to the wall of the outline of the shell, and two branches extending in opposition to a end of the body to keep the power cord wrapped around the body.
Selon une réalisation de l’appareil de cuisson, outre les caractéristiques précitées, le boîtier externe est agencé pour former une butée permettant de maintenir la paroi du contour de la coque à distance d’un plan vertical. Cela évite de mettre en contact la coque sur le plan vertical, par exemple une crédence murale. En outre, l’appareil de cuisson selon l’invention comprend une grille permettant une circulation d’air, ladite grille étant agencée sur ladite paroi, sur laquelle est agencé le boîtier externe constituant la butée. Ainsi, la grille est maintenue à distance du plan vertical, ce qui garantit une aspiration et/ou une ventilation convenable de l’appareil de cuisson sans obstruction de la grille. Selon une mise en œuvre préférentielle, le boîtier externe comprend un corps s’étendant perpendiculairement à la paroi du contour de la coque et deux branches s’étendant en opposition à une extrémité du corps en étant légèrement arquées dans une direction opposée à ladite paroi. Cela permet de maintenir l’extrémité du corps à distance du plan vertical et de prendre appui en deux points distants sur le plan vertical. De préférence, les deux branches disposent d’une souplesse pour amortir les chocs au contact du plan vertical. According to an embodiment of the cooking appliance, in addition to the aforementioned characteristics, the external casing is arranged to form a stop making it possible to keep the wall of the outline of the shell away from a vertical plane. it avoid bringing the shell into contact vertically, for example a wall splashback. In addition, the cooking appliance according to the invention comprises a grid allowing air circulation, said grid being arranged on said wall, on which is arranged the external housing constituting the stop. Thus, the grid is kept away from the vertical plane, which guarantees proper suction and / or ventilation of the cooking appliance without obstructing the grid. According to a preferred implementation, the external housing comprises a body extending perpendicular to the wall of the contour of the shell and two branches extending in opposition to one end of the body being slightly arched in a direction opposite to said wall. This allows the extremity of the body to be kept away from the vertical plane and to be supported at two distant points on the vertical plane. Preferably, the two branches have flexibility to absorb shocks in contact with the vertical plane.
Selon une réalisation de l’appareil de cuisson, le boîtier externe est agencé sur une paroi à l’arrière de la coque. En d’autres termes, la coque comprend une face avant par laquelle est manipulé ledit appareil de cuisson durant son utilisation. Par exemple, dans le cas de certaines friteuses, celles-ci comprennent une cuve qui est insérée ou retirée de la face avant de la coque à la manière d’un tiroir. D’autres friteuses comprennent un couvercle qui, en position ouverte, permet d’insérer ou de retirer par le dessus un panier dont la poignée de manipulation est positionnée en face avant de la coque. D’autres appareils de cuisson comprennent une porte et/ou des boutons ou claviers de commande en face avant. En outre, selon cette réalisation, la coque comprend une face arrière opposée à la face avant, le boîtier externe étant agencé sur la paroi se trouvant sur la face arrière de la coque. On pourrait toutefois envisager d’autres positions du boîtier externe sur le contour de la coque et selon l’appareil en question, par exemple sur une paroi latérale d’un grille-pain. According to an embodiment of the cooking appliance, the external casing is arranged on a wall at the rear of the shell. In other words, the shell comprises a front face by which said cooking appliance is manipulated during its use. For example, in the case of certain fryers, these include a tank which is inserted or removed from the front face of the shell in the manner of a drawer. Other fryers include a cover which, in the open position, makes it possible to insert or remove a basket from above, the handling handle of which is positioned on the front of the shell. Other cooking appliances include a door and / or buttons or keypads on the front panel. In addition, according to this embodiment, the shell comprises a rear face opposite to the front face, the external housing being arranged on the wall located on the rear face of the shell. One could however consider other positions of the external housing on the contour of the shell and according to the device in question, for example on a side wall of a toaster.
Selon une réalisation de l’appareil de cuisson, celui-ci est une friteuse, en particulier une friteuse à air chaud, une telle friteuse utilisant très peu d’huile, voire pas du tout. On peut toutefois envisager l’invention sur une friteuse à bain d’huile, pour laquelle les aliments baignent dans l’huile durant la cuisson, ou sur d’autres appareils de cuisson, par exemple un mini-four électrique ou un grille- pain. According to one embodiment of the cooking appliance, the latter is a fryer, in particular a hot air fryer, such a fryer using very little oil, if at all. However, the invention can be envisaged on an oil fryer, in which the food is immersed in oil during cooking, or on other cooking appliances, such as an electric mini-oven or a toaster.

Tel qu’illustré sur la figure 1 , la friteuse 1 comprend une coque 2 comportant un contour 3 qui présente une forme plus ou moins parallélépipédique, avec une paroi 4 disposée en face arrière 1a de la friteuse 1 , tandis que la face avant 1 b de cette friteuse 1 permet l’insertion d’une cuve 5 à la manière d’un tiroir dans une enceinte de cuisson 6, la cuve 5 étant manipulée au moyen d’une poignée de manipulation 7. D’autres formes du contour 3 sont envisageables, par exemple un contour 3 plus ou moins cylindrique. Tel qu’illustré sur la figure 1 , un système de chauffe 8 est agencé à l’intérieur de la coque 2, au-dessus de l’enceinte de cuisson 6. La coque 2 incorpore un système de commande destiné à commander le système de chauffe 8. De même, un système de ventilation 9 est agencé dans la coque 2, au-dessus du système de chauffe 8. Ce système de ventilation 9 permet d’aspirer de l’air frais au travers d’une partie supérieure 10a d’une grille 10 agencée sur la paroi 4, cet air circulant dans un conduit d’aspiration 11 puis au travers du système de chauffe 8 afin d’être chauffé et, enfin, dans l’enceinte de cuisson 6, avant d’être refoulé par un circuit d’évacuation 12 débouchant en partie inférieure 10b de cette grille 10. Les divers organes électriques de la friteuse 1 , dont notamment le système de chauffe 8 et le système de ventilation 9, sont raccordés à un circuit d’alimentation électrique (non illustré) qui comporte notamment une carte électronique de commande (non illustrée). Toutes ces caractéristiques sont déjà connues sur les friteuses actuellement sur le marché, raison pour lesquelles elles ne seront pas détaillées ; l’homme du métier pourra par exemple se référer aux friteuses à air chaud développées par la demanderesse, notamment celle commercialisée sous la dénomination FRY DELIGHT®. As illustrated in FIG. 1, the fryer 1 comprises a shell 2 comprising an outline 3 which has a more or less parallelepiped shape, with a wall 4 arranged on the rear face 1a of the fryer 1, while the front face 1b of this fryer 1 allows the insertion of a tank 5 in the manner of a drawer in a cooking enclosure 6, the tank 5 being manipulated by means of a handling handle 7. Other shapes of the outline 3 are conceivable, for example a more or less cylindrical contour 3. As illustrated in FIG. 1, a heating system 8 is arranged inside the shell 2, above the cooking enclosure 6. The shell 2 incorporates a control system intended to control the heating system. heater 8. Likewise, a ventilation system 9 is arranged in the shell 2, above the heating system 8. This ventilation system 9 allows fresh air to be drawn through an upper part 10a d '' a grid 10 arranged on the wall 4, this air circulating in a suction duct 11 then through the heating system 8 in order to be heated and, finally, in the cooking chamber 6, before being discharged by a discharge circuit 12 opening into the lower part 10b of this grid 10. The various electrical components of the fryer 1, including in particular the heating system 8 and the ventilation system 9, are connected to an electrical supply circuit ( not shown) which includes an electronic control card from (not shown). All these characteristics are already known on fryers currently on the market, which is why they will not be detailed; the art could for example refer to the hot air fryers developed by the applicant, in particular that sold under the name FRY DELIGHT ®.
La friteuse 1 est alimentée électriquement au moyen d’un cordon d’alimentation électrique, non illustré sur les figures, comme cela est le cas traditionnellement sur les appareils de cuisson électriques. Le cordon d’alimentation électrique de la friteuse 1 comprend généralement une prise mâle conçue qui est embrochée sur une prise femelle complémentaire agencée sur une paroi murale ; on peut aussi envisager que ce cordon d’alimentation électrique soit raccordé directement sur une sortie de câble agencée sur cette paroi murale, pour d’autres conceptions d’appareils de cuisson. L’extrémité du cordon d’alimentation électrique est connectée au circuit d’alimentation électrique de la friteuse par l’intermédiaire d’un bornier de raccordement, non illustré sur les figures. The fryer 1 is supplied electrically by means of an electrical supply cord, not illustrated in the figures, as is traditionally the case on electric cooking appliances. The power supply cord of the fryer 1 generally comprises a designed male plug which is plugged into a complementary female plug arranged on a wall; it is also conceivable that this electrical supply cord is connected directly to a cable outlet arranged on this wall wall, for other designs of cooking appliances. The end of the power supply cord is connected to the power supply circuit of the fryer via a connection terminal block, not shown in the figures.
Tel qu’illustré sur les figures 1 et 2, la friteuse 1 comprend en face arrière 1 a, un boîtier externe 13 qui est fixé sur la paroi 4, par exemple par vissage. Ce boîtier externe 13 comprend un corps 14 qui s’étend perpendiculairement à la paroi 4, selon un axe X, et deux branches 15, 16 agencées au niveau de l’extrémité 14a du corps 14. Ces deux branches 15, 16 sont disposées en opposition et s’étendent en formant un arc dans une direction opposée à la paroi 4, tel qu’illustré sur ces figures 1 et 2. Cette conception du boîtier externe 13 présente plusieurs avantages. As illustrated in Figures 1 and 2, the fryer 1 comprises on the rear face 1a, an external housing 13 which is fixed to the wall 4, for example by screwing. This external housing 13 comprises a body 14 which extends perpendicular to the wall 4, along an axis X, and two branches 15, 16 arranged at the end 14a of the body 14. These two branches 15, 16 are arranged in opposition and extend by forming an arc in a direction opposite to the wall 4, as illustrated in these figures 1 and 2. This design of the external housing 13 has several advantages.
En effet, lorsque la friteuse 1 repose sur un plan horizontal 17, par exemple un plan de cuisine, et est positionnée à proximité d’un plan vertical 18, par exemple une crédence murale, comme illustré en figure 2, les extrémités 15a, 16a des branches 15, 16 viennent en butée contre le plan vertical 18, ce qui permet de maintenir la paroi 4 de la friteuse 1 à distance dudit plan vertical 18. En outre, ce maintien de la paroi 4 à distance du plan vertical 18 évite de rapprocher trop la grille 10 dudit plan vertical 18, afin que l’aspiration de l’air frais et le refoulement de l’air chaud par cette grille 10 se fassent correctement, sans obstruction, lors du fonctionnement du système de ventilation 9. De préférence, les branches 15, 16 disposent d’une souplesse, ce qui permet d’amortir légèrement les chocs lorsque le boîtier externe 13 vient brusquement en butée contre le plan vertical 18. Indeed, when the fryer 1 rests on a horizontal plane 17, for example a kitchen plan, and is positioned near a vertical plane 18, for example a wall splashback, as illustrated in FIG. 2, the ends 15a, 16a branches 15, 16 abut against the vertical plane 18, which keeps the wall 4 of the fryer 1 away from said vertical plane 18. In addition, this maintenance of the wall 4 away from the vertical plane 18 avoids bringing the grid 10 too close to said vertical plane 18, so that the suction of fresh air and the discharge of hot air by this grid 10 are done correctly, without obstruction, during the operation of the ventilation system 9. Preferably , the branches 15, 16 have flexibility, which makes it possible to slightly absorb shocks when the external housing 13 abruptly abuts against the vertical plane 18.
Par ailleurs, le cordon d’alimentation électrique, tel que précité, peut avantageusement être enroulé autour du corps 14 lorsque la friteuse 1 n’est pas utilisée ou lorsque la prise femelle complémentaire, sur laquelle est branchée la prise mâle du cordon d’alimentation électrique, est positionnée à proximité de la friteuse 1. Le corps 14 a de préférence une forme ovale pour réduire son encombrement en largeur, mais on peut envisager d’autres formes, par exemple une forme cylindrique. Cette forme ovale facilite l’enroulement du cordon d’alimentation électrique autour du corps 14. Furthermore, the electrical supply cord, as mentioned above, can advantageously be wound around the body 14 when the fryer 1 is not in use or when the complementary female plug, to which the male plug of the power cord is connected electric, is positioned near the fryer 1. The body 14 preferably has an oval shape to reduce its overall width, but other shapes can be envisaged, for example a cylindrical shape. This oval shape facilitates the winding of the electrical supply cord around the body 14.
Tel qu’illustré sur les figures 1 et 2, le corps 14 du boîtier externe 13 comprend un orifice 19 qui débouche dans une zone de logement 20 agencée à l’intérieur du boîtier externe 13. Cet orifice 19 permet le passage de l’extrémité du cordon d’alimentation électrique ; en outre, la zone de logement 20 est dimensionnée pour réceptionner le bornier de raccordement assurant la connexion entre l’extrémité du c ordon d’alimentation électrique et le circuit d’alimentation électrique alimentant les divers organes électriques de la friteuse 1. Pour cela, des fils électriques du circuit d’alimentation électrique passent au travers de la paroi 4 et du boîtier externe 13 pour venir se connecter au cordon d’alimentation électrique par le biais du bornier de raccordement. En déportant le bornier de raccordement en dehors de la coque 2, cela limite considérablement les échauffements au niveau de l’extrémité du cordon d’alimentation électrique et du bornier de raccordement. Afin de mieux réduire ces échauffements, le boîtier externe 13 comprend une chambre d’isolation 21 qui est positionnée en avant de la zone de logement 20, c’est-à-dire entre la zone de logement 20 et la paroi 4. Cela permet de réduire la conduction thermique de la paroi 4 vers la zone de logement 20. Cette conduction thermique est par ailleurs atténuée grâce à la présence d’ouïes d’aération 22 sur le corps 14 qui débouchent dans la chambre d’isolation 21 et la traversent de manière à permettre la circulation de l’air naturelle dans celle- ci. As illustrated in FIGS. 1 and 2, the body 14 of the external housing 13 includes an orifice 19 which opens into a housing zone 20 arranged inside the external housing 13. This orifice 19 allows the passage of the end the power supply cord; in addition, the housing zone 20 is dimensioned to receive the connection terminal block ensuring the connection between the end of the electrical power supply cord and the electrical power supply circuit supplying the various electrical components of the fryer 1. For this, electrical wires from the electrical supply circuit pass through the wall 4 and the external housing 13 to connect to the electrical supply cord via the connection terminal block. By moving the connection terminal outside the shell 2, this considerably limits overheating at the end of the electrical supply cord and the connection terminal. In order to better reduce these overheating, the external housing 13 comprises an isolation chamber 21 which is positioned in front of the housing zone 20, that is to say between the housing zone 20 and the wall 4. This allows reduce the thermal conduction from the wall 4 to the housing zone 20. This thermal conduction is moreover attenuated by the presence of air vents 22 on the body 14 which open into the insulation chamber 21 and pass through it so as to allow the circulation of natural air in it.
La mise en œuvre du boîtier externe 13 présentant les caractéristiques précitées, pallie ainsi le problème d’échauffement du cordon d’alimentation électrique et, en outre, assure le maintien dégagé de la grille 10 pour le bon fonctionnement du système de ventilation 9 et évite que la coque 2 - qui chauffe - soit en contact avec le plan vertical 18. Bien entendu la mise en œuvre d’un tel boîtier externe 13 peut être envisagée sur les coques d’autres appareils de cuisson que la friteuse 1 , sans sortir du cadre de l’invention, en adaptant la position du boîtier externe selon les configurations de ces appareils de cuisson. The implementation of the external housing 13 having the above characteristics, thus overcomes the problem of overheating of the electrical supply cord and, moreover, ensures the unobstructed maintenance of the grid 10 for the proper functioning of the ventilation system 9 and avoids that the shell 2 - which heats - is in contact with the vertical plane 18. Of course the implementation of such an external box 13 can be envisaged on the hulls of other cooking appliances than the fryer 1, without leaving the part of the invention, by adapting the position of the external housing according to the configurations of these cooking appliances.
