Abstract
Description
La présente invention est relative à une table de cuisson ou appareil similaire comportant un système de ventilation, la table comprenant notamment une plaque supérieure en verre armé ou en un matériau céramique transparent, des foyers de chauffage répartis sous la plaque et un caisson dans lequel sont montés ces foyers et leurs organes d'alimentation électrique et de contrôle de leur fonctionnement, ce caisson fixé sous la plaque présentant une épaisseur relativement réduite et dont le contour généralement carré ou rectangulaire, permet son encastrement dans un logement adéquat ménagé à la partie supérieure d'un meuble ou d'un élément de support analogue, qui s'intègre dans l'aménagement d'une cuisine domestique ou autre.The present invention relates to a hob or similar device with a ventilation system, the table including a glass top plate armed or in a transparent ceramic material, fireplaces heating distributed under the plate and a box in which these fireplaces and their supply members are fitted electric and control of their operation, this box fixed under the plate having a relatively thick reduced and whose generally square outline or rectangular, allows its installation in a housing suitable for the upper part of a piece of furniture or similar support element, which fits into the development of a domestic or other kitchen.
Dans les solutions actuelles pour ce type de tables de cuisson (voir notamment US 4549052), l'utilisation de circuits électroniques est de plus en plus fréquente, notamment pour assurer le contrôle automatique de la commande des foyers de chauffage et la régulation de la température qu'ils permettent d'atteindre au droit de ces foyers à travers la plaque vitrocéramique. En outre, avec des foyers où ce chauffage est réalisé, non plus au moyen de résistances électriques ou de lampes à halogène, mais dans les réalisations les plus récentes à l'aide d'un enroulement magnétique fonctionnant par induction et se couplant à travers la plaque de verre avec l'ustensile de cuisson métallique reposant sur cette plaque au-dessus du foyer considéré, il est indispensable de réaliser une ventilation énergique de la table et en particulier des circuits électroniques ainsi montés à l'intérieur du caisson placé sous la plaque.In current solutions for this type of tables cooking (see in particular US 4549052), the use of electronic circuits is more and more frequent, especially to ensure automatic control of the control of the heating zones and regulation of the temperature they allow to reach to the right of these hearths through the ceramic hob. In addition, with homes where this heating is carried out, no longer by means of electric resistors or halogen lamps, but in the most recent achievements using a winding magnetic operated by induction and coupled to through the glass plate with the cooking utensil metal resting on this plate above the hearth considered, it is essential to carry out a ventilation energetic of the table and in particular of the circuits electronics thus mounted inside the box placed under the plate.
En particulier, on constate qu'avec des foyers de chauffage de ce dernier type, aussi bien mais plus encore qu'avec ceux plus conventionnels mettant en oeuvre des résistances électriques ou des sources de rayonnement par infrarouge, les pertes d'énergie dans la table et par suite dans le meuble où elle s'encastre, représentent près de 20 % de la puissance fournie, ce qui provoque une élévation notable de la température de certains composants du circuit de commande ou de contrôle, notamment des transistors qui réalisent la commutation de puissance nécessaire pour permettre les diverses allures de chauffe souhaitées par l'utilisateur de la table de cuisson.In particular, we note that with heating fireplaces of the latter type, as well but even more so than with those more conventional using resistors electrical or infrared sources of radiation, energy losses in the table and consequently in the furniture where it fits, represent almost 20% of the power supplied, which causes a noticeable rise in the temperature of certain components of the control circuit or control, in particular transistors which carry out the switching power required to allow various heating stages desired by the user of the hob.
Pour assurer ce refroidissement, on utilise de façon classique un ventilateur (voir le FR-A-2 417 725), du type centrifuge ou du genre dit tangentiel, dont les dimensions en épaisseur peuvent être suffisamment réduites pour permettre son logement dans le caisson monté sous la plaque à l'intérieur de la table.To ensure this cooling, we use conventional a fan (see FR-A-2 417 725), of the type centrifugal or of the so-called tangential kind, the dimensions of which in thickness can be reduced enough to allow it to be housed in the box mounted under the plate inside the table.
Mais, pour procurer le refroidissement nécessaire, le ventilateur doit disposer d'une prise d'air et d'une section de refoulement de dimensions suffisantes. Dans les réalisations actuelles, l'aspiration s'effectue directement dans le meuble, ce qui nécessite de pratiquer dans celui-ci des ouvertures convenables avec découpes du plancher, du fond et le cas échéant du tiroir ou de la porte de ce meuble, avoisinant le logement du caisson, le refoulement s'effectuant généralement dans la partie arrière de celui-ci, à l'opposé de sa face frontale visible de l'extérieur.But, to provide the necessary cooling, the fan must have an air intake and a section discharge of sufficient dimensions. In the current achievements, aspiration takes place directly in the furniture, which requires practicing in it suitable openings with cutouts from the floor, bottom and if applicable of the drawer or door of this furniture, around the housing of the box, the discharge generally taking place in the rear part of this one, opposite to its visible front face of outside.
Il est donc impossible d'encastrer une telle table dans un meuble entièrement fermé. De plus, les découpes nécessaires pour réaliser dans le meuble les orifices d'aspiration et de refoulement sont le plus souvent à pratiquer sur place, lors du montage de la table, ce qui est généralement délicat et exige un temps non négligeable, en fonction du profil du meuble ou de la pièce dans laquelle il s'intègre.It is therefore impossible to embed such a table in a fully closed piece of furniture. In addition, the cutouts necessary to make the holes in the cabinet suction and discharge are most often practice on site, when mounting the table, which is generally delicate and requires time not negligible, depending on the profile of the furniture or the room in which it fits.
Enfin, ces opérations peuvent conduire à un encastrement final qui n'est plus parfaitement ajusté, d'où des possibilités de surchauffes locales, avec d'éventuelles conséquences sur la durée de vie de la table elle-même.Finally, these operations can lead to embedding final which is no longer perfectly adjusted, resulting in possibilities of local overheating, with possible consequences on the life of the table itself.
La présente invention a pour objet une table de cuisson comportant un système de ventilation, qui évite ces inconvénients, cette table avec sa plaque supérieure vitrocéramique et son caisson inférieur formant un ensemble autonome, apte à être refroidi en fonctionnement sans nécessiter aucune prise d'air à réaliser dans le meuble où elle s'encastre.The present invention relates to a hob with a ventilation system, which avoids these disadvantages, this table with its top plate glass ceramic and its lower box forming a autonomous assembly, capable of being cooled in operation without requiring any air intake to be carried out in the piece of furniture where it fits.
A cet effet, la table de cuisson considérée comportant un système de ventilation, une plaque de verre ou analogue à sa partie supérieure, un caisson plat inférieur, logeant un et de préférence plusieurs foyers de chauffage montés à l'intérieur du caisson et des organes électriques et électroniques de commande et de régulation de ces foyers, ainsi qu'un ventilateur de refroidissement, la plaque de verre étant supportée par une cornière périphérique du caisson, cette cornière reposant par l'intermédiaire d'une portée d'appui horizontale sur un meuble recevant la table dans un espace d'encastrement de dimensions correspondantes et présentant un rebord sensiblement vertical, ce rebord comprenant des passages respectivement pour l'entrée de l'air ambiant aspiré par le ventilateur et pour la sortie de cet air après refoulement à l'intérieur du caisson, ces passages étant de préférence disposés dans des côtés opposés de la cornière, se caractérise en ce que le caisson plat inférieur est solidaire de la plaque et disposé sous celle-ci en formant un ensemble autonome, le rebord vertical étant muni d'une extension latérale sur laquelle s'applique la plaque à l'intérieur de la cornière.To this end, the cooktop considered comprising a ventilation system, a glass plate or the like its upper part, a lower flat box, housing one and preferably several mounted fireplaces inside the box and the electrical components and electronic control and regulation of these fireplaces, as well as a cooling fan, the glass being supported by a peripheral angle of the box, this angle resting through a horizontal bearing surface on a piece of furniture the table in a built-in space of dimensions corresponding and having a substantially rim vertical, this rim comprising passages respectively for the entry of ambient air drawn in by the fan and for the exit of this air after discharge inside the box, these passages being preferably arranged in opposite sides of the angle, is characterized in that the flat box lower is integral with the plate and arranged under this by forming an autonomous whole, the rim vertical being provided with a lateral extension on which apply the plate inside the angle.
Avantageusement, les passages d'entrée de l'air ménagés dans le rebord de la cornière sont prévus vers l'avant du caisson et les passages de sortie vers l'arrière de celui-ci. Toutefois et en variante, ces passages peuvent être prévus sur les côtés latéraux de la cornière.Advantageously, the air intake passages provided in the edge of the angle iron are provided towards the front of the box and exit passages to the rear of this one. However and as a variant, these passages can be provided on the lateral sides of the angle iron.
Selon un mode de réalisation préféré, la cornière périphérique entourant la plaque de verre est creuse et comporte un retour vers l'extérieur légèrement arrondi dont l'extrémité est en contact avec la portée d'appui horizontale de la table.According to a preferred embodiment, the angle device surrounding the glass plate is hollow and has a slightly rounded outward return the end of which is in contact with the bearing surface table horizontal.
Selon le cas, le caisson comporte un fond inférieur formé d'une tôle plane ou présente un double fond délimité par deux tôles parallèles ménageant entre elles un espace de circulation de l'air refoulé par le ventilateur.Depending on the case, the box has a bottom bottom formed of a flat sheet or has a double bottom delimited by two parallel sheets leaving a space between them circulation of the air discharged by the fan.
Dans un mode de réalisation également préféré, le ventilateur est logé à l'intérieur du caisson à proximité du côté de celui-ci comportant les orifices d'entrée d'air.In an equally preferred embodiment, the fan is housed inside the nearby cabinet on the side thereof having the inlet ports of air.

- Figure 4 is a view similar to Figure 3 but relating to an alternative embodiment.
Sur la Figure 1, la référence 1 désigne une table de cuisson constituée d'une plaque supérieure 2, en verre armé ou en un matériau vitrocéramique et d'un caisson inférieur 3, disposé sous la plaque 2 et contenant notamment des foyers de chauffage (non représentés), répartis convenablement sous la plaque, ces foyers pouvant comporter selon le cas des résistances électriques, des lampes halogènes délivrant un rayonnement infrarouge ou encore des enroulements magnétiques pour réaliser un chauffage à induction par couplage avec des ustensiles métalliques placés sur le dessus de la plaque 2.In Figure 1, reference 1 designates a hob consisting of an upper plate 2, in reinforced glass or in a glass-ceramic material and a bottom box 3, arranged under plate 2 and containing in particular hearths of heating (not shown), suitably distributed under the plate, these hearths being able to comprise according to the case of electric resistors, halogen lamps delivering a infrared radiation or windings magnetic to realize an induction heating by coupling with metal utensils placed on the above the plate 2.
La table 1 est prévue pour être encastrée à l'intérieur d'un meuble de support 4 présentant un logement 5 de dimensions appropriées dans lequel vient s'encastrer la table 1 et en particulier le caisson 3 disposé sous la plaque de verre 2.Table 1 is designed to be built into a support cabinet 4 having a housing 5 of dimensions in which table 1 is fitted and in in particular the box 3 placed under the glass plate 2.
Conformément à l'invention, la table 1 repose sur une portée d'appui horizontale 6 du meuble 4 par l'intermédiaire d'une cornière métallique 7 comprenant une extension latérale 8 sur laquelle s'applique le bord périphérique externe de la plaque 2, cette extension comprenant un rebord sensiblement vertical 9 entourant à sa périphérie la plaque de verre.According to the invention, table 1 is based on a span horizontal support 6 of the cabinet 4 via a metal angle 7 comprising a lateral extension 8 to which the outer peripheral edge of the plate 2, this extension comprising a rim substantially vertical 9 surrounding at its periphery the glass plate.
Selon le cas, le rebord 9 s'étendant à partir de l'extension 8 supportant la plaque 2 peut comporter une extrémité 10 fermée sur elle-même, comme représenté sur la Figure 1, ou se prolonger par un retour 11 s'étendant vers l'extérieur comme illustré sur la Figure 2, ce retour présentant dans ce cas un profil arrondi terminé par une extrémité rabattue 12 venant au contact ou au voisinage immédiat de la portée d'appui 6.As the case may be, the rim 9 extending from the extension 8 supporting the plate 2 may have one end 10 closed on itself, as shown in Figure 1, or be extended by a return 11 extending outwards as illustrated in Figure 2, this return presenting in this case a rounded profile ending with a folded end 12 coming into contact or in the immediate vicinity of the litter support 6.
La cornière 7 comprend une pluralité de passages tels que 13 et 14 ménagés dans son rebord vertical 9, permettant de faire communiquer à travers ceux-ci l'extérieur de la table 1 et l'intérieur du meuble 4 dans le logement 5 où s'encastre la table, les passages 13 étant par exemple réservés à une aspiration de l'air ambiant à l'intérieur de la cornière 7, tandis que les passages 14 permettent l'évacuation simultanée de l'air ainsi aspiré.The angle 7 includes a plurality of passages such as 13 and 14 formed in its vertical edge 9, making it possible to communicate through these outside the table 1 and the interior of the cabinet 4 in the housing 5 where fits the table, the passages 13 being for example reserved for extracting ambient air inside the angle 7, while the passages 14 allow the simultaneous evacuation of the air thus sucked.
Avantageusement, la cornière 7 comprend une plaque inférieure 15 avec un retour vertical 16 s'engageant dans le logement 5, notamment dans le jeu 17 ménagé entre le bord correspondant de la table 4 et les côtés du caisson 3, afin d'assurer un positionnement et un centrage adéquat de la table 1 lors de son encastrement dans ce logement.Advantageously, the angle iron 7 comprises a plate lower 15 with a vertical return 16 engaging in the housing 5, in particular in clearance 17 formed between the edge table 4 and the sides of the box 3, so ensure adequate positioning and centering of the table 1 when it is embedded in this housing.
Comme on le voit plus particulièrement sur la Figure 3, le caisson 3 prévu sous la plaque de verre 2 contient, sous la plaque 2 un ventilateur 18 dont le détail de la réalisation n'apporte pas directement à l'invention, ce ventilateur pouvant être notamment du type centrifuge ou tangentiel, le seul impératif à satisfaire étant qu'il puisse se loger à l'intérieur du caisson sans gêner la mise en place dans celui-ci des foyers de chauffage fournissant la chaleur nécessaire à la cuisson à travers la plaque 2.As seen more particularly in Figure 3, the box 3 provided under the glass plate 2 contains, under the plate 2 a fan 18, the detail of which is produced does not directly contribute to the invention, this fan can be in particular of the centrifugal or tangential type, the only imperative to satisfy being that it can be housed in inside the box without interfering with the installation in this one heating furnaces providing the heat necessary for cooking through the plate 2.
Sur la Figure 3, on a également schématisé, sous la référence 19 un circuit électronique de commande des foyers de chauffage de la table 1 et de régulation de la température délivrée par ces foyers selon les diverses allures de chauffe choisies par l'utilisateur.In Figure 3, we have also schematized, under the reference 19 an electronic stove control circuit for heating table 1 and regulating the temperature delivered by these homes according to the various heating stages chosen by the user.
Dans l'exemple illustré sur la Figure 3, l'air qui pénètre dans le jeu 17, entre le côté du logement 5 et le bord du caisson 3 en provenant des passages 13, circule d'abord dans l'espace 20 ménagé entre le fond 21 en tôle notamment de ce caisson et le plancher 22 du logement 5 avant d'être aspiré par la turbine 23 du ventilateur 18 au travers d'un orifice 24 prévu dans le fond 21 au droit de cette turbine.In the example illustrated in Figure 3, the air that enters in clearance 17, between the side of the housing 5 and the edge of the box 3 from passages 13, first flows in the space 20 formed between the bottom 21 in sheet metal in particular of this box and the floor 22 of the housing 5 before being drawn by the turbine 23 of the fan 18 through a orifice 24 provided in the bottom 21 to the right of this turbine.
L'air ainsi aspiré est refoulé à grand débit par la turbine à l'intérieur même du caisson 3 et en particulier sur le circuit électronique 19 qu'il refroidit énergiquement avant d'être refoulé hors du caisson à l'extrémité opposée de celui-ci par les passages 14.The air thus sucked in is discharged at high speed through the turbine inside the box 3 and in particular on the electronic circuit 19 that it cools vigorously before being forced out of the box at the opposite end of this one through passages 14.
Dans la variante illustrée sur la Figure 4, le montage est légèrement différent, le caisson 3 comportant un double fond délimité par la tôle 21 et une tôle parallèle 25 située sous la première, délimitant entre elles un espace de circulation 26. Des orifices 27 sont prévus aux extrémités de cet espace de circulation de telle sorte que l'air aspiré dans le jeu 17 à travers les passages 13 y prénètre, soit ensuite repris par la turbine 23 en passant dans l'orifice de communication 24 de la tôle 21, puis refoulé par celle-ci à la fois à l'intérieur du caisson pour refroidir le circuit électronique ici non représenté et dans l'espace 26 pour maintenir le fond du caisson et la partie en regard du meuble 4 à une température basse satisfaisante.In the variant illustrated in Figure 4, the assembly is slightly different, box 3 having a double bottom delimited by the sheet 21 and a parallel sheet 25 located under the first, delimiting between them a circulation space 26. Holes 27 are provided at the ends of this space of circulation so that the air sucked into the game 17 through passages 13 enter, then be resumed by the turbine 23 passing through the orifice of communication 24 of the sheet 21, then driven back by the latter to both inside the box to cool the circuit electronics here not shown and in space 26 for maintain the bottom of the box and the part facing the cabinet 4 at a satisfactory low temperature.
Les passages d'entrée et de sortie 13 et 14 de l'air aspiré puis refoulé par le ventilateur 18 peuvent se présenter sous la forme de trous ménagés dans le rebord vertical 9 de la cornière, comme illustré sur la Figure 2, ou bien épouser la forme de fentes plus ou moins allongées.The entrance passages and outlet 13 and 14 of the air sucked in then discharged by the fan 18 can be in the form of holes formed in the vertical edge 9 of the angle iron, as illustrated in Figure 2, or follow the shape of more or less elongated slits.
De préférence, les orifices d'entrée sont ménagés sur un des côtés latéraux ou sur la face avant de la cornière 7, les orifices de sortie étant disposés sur le côté opposé ou la face arrière ; toutefois, tout autre aménagement pourrait être envisagé.Preferably, the inlet orifices are provided on one of the lateral sides or on the front face of the angle iron 7, the outlet ports being disposed on the opposite side or the back side; however, any other development could to be considered.
L'invention ne préjuge nullement de la profondeur d'encastrement de la table de cuisson, pour autant que celle-ci permette le logement du caisson et, dans celui-ci du ventilateur, ce dernier pouvant par ailleurs, comme déjà indiqué, être du type centrifuge, tangentiel ou hélicoide. Dans tous les cas, la solution proposée permet un encastrement sûr de la table sans contraintes spécifiques et sans notamment nécessiter d'interventions sur le meuble qui la reçoit, dont les cotes peuvent être ainsi particulièrement bien ajustées.The invention in no way prejudges the depth of the hob, provided that this allows the housing of the box and, in it fan, which can also, as already indicated, be of the centrifugal, tangential or helical type. In all cases, the proposed solution allows a safe installation of the table without specific constraints and without in particular requiring interventions on the furniture which receives it, whose ratings may be as well particularly well adjusted.
