Description

L'invention concerne un dispositif de support des moyens de commande pour appareil ménager qui, mobile, permet de modifier l'esthétique de l'appareil selon qu'il est ou non en fonctionnement et d'assurer une ventilation correcte pour son refroidissement en fonctionnement.The invention relates to a device for supporting control means for a household appliance which, mobile, makes it possible to modify the aesthetics of the appliance according to whether or not it is in operation and to ensure correct ventilation for its cooling in operation. .

Dans le cas des tables de cuisson par induction, l'électronique de puissance doit être refroidie et, pour ce faire, il est connu de la placer dans un circuit de ventilation qui s'étend sous la table de cuisson depuis l'arrière de l'appareil (vide sanitaire) vers l'avant où des orifices sont prévus pour la sortie d'air chaud. Certaines de ces tables sont intégrées dans une carrosserie et c'est dans celle- ci que la circulation de ventilation est réalisée. D'autres sont dites encastrables dans un support séparé et la gaine de ventilation sera réalisée plus ou moins bien par l'installateur, notamment en ce qui concerne l'évacuation de l'air chaud. Cet état de la technique est décrit, par exemple, dans le FR-A-2 340 513.In the case of induction hobs, the power electronics must be cooled and, to do this, it is known to place it in a ventilation circuit which extends under the hob from the rear of the 'appliance (crawl space) forward where openings are provided for the outlet of hot air. Some of these tables are integrated in a bodywork and it is in this body that the ventilation circulation is carried out. Others are said to be built into a separate support and the ventilation duct will be made more or less well by the installer, in particular as regards the evacuation of the hot air. This state of the art is described, for example, in FR-A-2,340,513.

L'invention permet dans tous les cas de préserver une confection correcte du circuit de ventilation, notamment dans le cas d'appareils encastrables, grâce à un montage et une réalisation particulièrs du bandeau de support des moyens de commande (boutons, touches...) de l'appareil. Ce montage permet en outre de modifier l'esthétique de l'appareil en masquant ces moyens lorsque l'appareil n'est pas en fonctionnement.The invention makes it possible in all cases to preserve a correct construction of the ventilation circuit, in particular in the case of built-in appliances, by means of a particular mounting and embodiment of the support strip for the control means (buttons, keys, etc.). ) of the device. This arrangement also makes it possible to modify the aesthetics of the device by masking these means when the device is not in operation.

A cet effet, l'invention prévoit un dispositif de support des moyens de commande pour un appareil ménager enclos au moins en partie dans un boîtier muni d'un circuit de ventilation interne ayant un orifice de sortie à proximité des moyens de commande, ce dispositif comprenant un corps monté sur le boîtier ayant une face sur laquelle les moyens de commande sont disposés, ce corps étant mobile entre une première position, où les moyens de commande sont accessibles, et une deuxième position, où ils ne le sont pas et constituant un organe d'ouverture de l'orifice de sortie dans sa première position et un organe de fermeture de l'orifice de sortie dans sa deuxième position.To this end, the invention provides a device for supporting the control means for a household appliance enclosed at least in part in a box provided with an internal ventilation circuit having an outlet orifice near the control means, this device comprising a body mounted on the housing having a face on which the control means are arranged, this body being movable between a first position, where the control means are accessible, and a second position, where they are not and constituting a outlet opening member in its first position and a member for closing the outlet orifice in its second position.

Selon une caractéristique de l'invention, le corps comprend un passage ayant une première extrémité débouchant dans le boîtier et une seconde extrémité ouvrant à proximité de la face où sont disposés les moyens de commande et débouchant sur l'extérieur lorsque le corps est dans la première position, cette seconde extrémité constituant l'orifice de sortie.According to a characteristic of the invention, the body comprises a passage having a first end opening into the housing and a second end opening close to the face where the control means are arranged and opening to the outside when the body is in the first position, this second end constituting the outlet orifice.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante de trois modes de réalisation de l'invention, donnés à titre d'exemple et sans intentions limitatives. On se reportera aux dessins annexés sur lesquels :

  • la figure 1 est une vue de côté schématique, en coupe partielle, d'une table de cuisson encastrée dans un meuble de support, en fonctionnement ;
  • la figure 2 est une vue partielle de côté, schématique, en coupe, du dispositif de support des moyens de commandes de la table représentée sur la figure 1,hors fonctionnement ;
  • les figures 3 et 4 sont des vues partielles de côté schématiques, d'un deuxième dispositif de support des moyens de commande d'une table de cuisson, hors fonctionnement (fig. 3) et en fonctionnement (fig. 4) ;
  • les figures 5, 6, 7 sont des vues partielles de côté schématiques, d'un troisième dispositif de support des moyens de commande d'une table de cuisson, hors fonctionnement (fig. 5) et en fonctionnement (fig. 6,7).
Other characteristics and advantages of the invention will appear on reading the following description of three embodiments of the invention, given by way of example and without limiting intentions. Reference is made to the appended drawings in which:
  • Figure 1 is a schematic side view, in partial section, of a hob embedded in a support cabinet, in operation;
  • Figure 2 is a partial side view, schematic, in section, of the device for supporting the control means of the table shown in Figure 1, out of operation;
  • Figures 3 and 4 are partial schematic side views of a second device for supporting the control means of a hob, not in operation (fig. 3) and in operation (fig. 4);
  • Figures 5, 6, 7 are partial schematic side views of a third device for supporting the control means of a hob, not in operation (fig. 5) and in operation (fig. 6,7) .

Sur la figure 1, on a représenté une table de cuisson 1 à chauffage par induction encastrée dans un meuble 2 comprenant un vide sanitaire 3 dans sa partie arrière. La table de cuisson 1 comprend une platine 4 supportant plusieurs plaques chauffantes 5 connectées, d'une façon connue en soi, à un système électronique de puissance constitué par des cartes de circuit 6 s'étendant sous les plaques 5. L'ensemble est enfermé dans un boîtier 7, dont la platine 4 forme la paroi supérieure.In Figure 1, there is shown a hob 1 with induction heating embedded in a cabinet 2 comprising a crawl space 3 in its rear part. The hob 1 comprises a plate 4 supporting several heating plates 5 connected, in a manner known per se, to an electronic power system constituted by cards circuit 6 extending under the plates 5. The assembly is enclosed in a housing 7, the plate 4 of which forms the upper wall.

La table de cuisson 1 comprend en outre un circuit de ventilation pour le refroidissement du système électronique. Ce circuit inclut un ventilateur 8 monté à proximité de la paroi arrière du boîtier 7 et caréné de façon à refouler de l'air selon une direction sensiblement parallèle aux cartes de circuits électroniques 6. Au niveau du ventilateur 8, le fond du boîtier 7 comprend un orifice 9 qui se trouve donc situé à l'aplomb du vide sanitaire 3, et par lequel se fait l'aspiration de l'air pulsé dans le boîtier 7.The hob 1 further comprises a ventilation circuit for cooling the electronic system. This circuit includes a fan 8 mounted near the rear wall of the housing 7 and streamlined so as to discharge air in a direction substantially parallel to the electronic circuit boards 6. At the level of the fan 8, the bottom of the housing 7 comprises an orifice 9 which is therefore located at the base of the crawl space 3, and by which the suction of the forced air takes place in the housing 7.

Sur l'avant de la table de cuisson 1, entre le bord avant de la platine 4 et la paroi avant du boîtier 7, sont disposés les moyens de commande 10 (boutons, touches ou similaires) qui permettent de régler l'intensité du chauffage des plaques 5. Les moyens de commande sont supportés par le dispositif selon l'invention, qui comprend un bandeau de commande 11 constitué par une face d'un corps allongé 12 monté sur le boîtier 7 de façon à pouvoir pivoter d'environ 90° autour de son axe longitudinal, entre une position où le bandeau 11 est totalement apparent (figure 1) et une position où il n'est pas visible (figure 2). Avantageusement, le corps 12 est rappelé dans l'une et l'autre de ces positions par des moyens élastiques (non représentés). Le corps 12 comprend des alvéoles où sont encastrés en partie les moyens de commande ainsi que les connections de ces moyens de commande aux câbles qui les relient au système électronique.On the front of the hob 1, between the front edge of the plate 4 and the front wall of the housing 7, are arranged the control means 10 (buttons, keys or the like) which make it possible to adjust the intensity of the heating plates 5. The control means are supported by the device according to the invention, which comprises a control panel 11 constituted by one face of an elongated body 12 mounted on the housing 7 so as to be able to pivot by approximately 90 ° around its longitudinal axis, between a position where the strip 11 is completely visible (Figure 1) and a position where it is not visible (Figure 2). Advantageously, the body 12 is returned to one and the other of these positions by elastic means (not shown). The body 12 comprises cells in which the control means are partially embedded as well as the connections of these control means to the cables which connect them to the electronic system.

Le corps 12 comprend aussi un dégagement 13 dont le fond s'étend sensiblement perpendiculairement au bord avant du bandeau de commande 11. Ce dégagement délimite un passage dont une première extrémité débouche toujours à l'intérieur du boîtier 7 et dont la seconde extrémité débouche soit à l'extérieur du boîtier 7, lorsque le corps 12 est basculé dans la position illustrée sur la figure 1, soit à l'intérieur du boîtier, lorsque le corps 12 est basculé dans la position illustrée sur la figure 2. Cette seconde extrémité constitue l'orifice de sortie du circuit de ventilation, qui est donc ouvert ou fermé selon que le corps est basculé dans l'une ou l'autre de ses deux positions.The body 12 also includes a recess 13, the bottom of which extends substantially perpendicular to the front edge of the control panel 11. This clearance delimits a passage, a first end of which always opens out inside the housing 7 and the second end of which opens either outside the housing 7, when the body 12 is tilted in the position illustrated in FIG. 1, that is to say inside the housing, when the body 12 is tilted in the position illustrated in FIG. 2. This second end constitutes the outlet orifice of the ventilation circuit, which is therefore open or closed depending on whether the body is tilted in one or the other of its two positions.

Par cette disposition, la mise en fonctionnement de la table de cuisson 1, quine peut se faire que si les moyens de commande 10 sont accessibles, entraîne nécessairement l'ouverture de l'orifice de sortie permettant à l'air pulsé par le ventilateur 8 de s'échapper, c'est-à-dire aussi permettant l'écoulement indispensable de l'air de ventilation autour du système électronique de puissance.By this arrangement, the operation of the hob 1, quine can be done if the control means 10 are accessible, necessarily leads to the opening of the outlet opening allowing the air blown by the fan 8 to escape, that is to say also allowing the indispensable flow of ventilation air around the electronic power system.

Pour éviter les conséquences fâcheuses qui se produiraient si,la table de cuisson étant en fonctionnement, le corps 12 était basculé dans la position illustrée sur la figure 2, on prévoit d'associer cette position à l'ouverture d'un interrupteur disposé sur le circuit d'alimentation de la table de cuisson.To avoid the unfortunate consequences which would occur if, the hob being in operation, the body 12 was tilted in the position illustrated on figure 2, one plans to associate this position with the opening of a switch arranged on the hob supply circuit.

Les figures 3 et 4 représentent un deuxième mode de réalisation du dispositif de support selon l'invention. Ce dispositif comprend un corps allongé 15 de section rectangulaire ayant une face supérieure constituant le bandeau de commande 11. Le corps 15 est guidé en translation contre la paroi avant du boîtier 7, selon une direction perpendiculaire à la platine 4. Le corps 15 est mobile entre une position où le bandeau de commande 11 est enfoncé par rapport à la platine 4 (figure 3) et une position où le bandeau de commande est en saillie par rapport à la platine (figure 4). Il comprend un dégagement 16 ouvrant sur sa face inférieure et sur sa face contiguë au boîtier 7, de sorte que, lorsqu'il est en position de saillie par rapport à la platine 4, une extrémité de ce dégagement débouche sur l'extérieur et constitue l'orifice de sortie du circuit de ventilation. Le corps 15 est soumis à l'action d'un organe élastique (non représenté) qui tend à le rappeler dans cette position. Un couvercle plat 17 est monté pivotant sur le boîtier 7 par des pattes en L 18 latérales ayant un segment parallèle au couvercle, l'axe de pivotement étant parallèle à la face supérieure du corps 15 et passant au niveau de l'extrémité libre des pattes 18. La fermeture de ce couvercle provoque l'enfoncement du corps 15 dans le boîtier 7 et son verrouillage en position enfoncée.Figures 3 and 4 show a second embodiment of the support device according to the invention. This device comprises an elongated body 15 of rectangular section having an upper face constituting the control panel 11. The body 15 is guided in translation against the front wall of the housing 7, in a direction perpendicular to the plate 4. The body 15 is movable between a position where the control panel 11 is pressed relative to the plate 4 (FIG. 3) and a position where the control panel is projecting relative to the plate (FIG. 4). It comprises a clearance 16 opening on its underside and on its face contiguous to the housing 7, so that, when it is in the projecting position relative to the plate 4, one end of this clearance opens onto the outside and constitutes the ventilation circuit outlet. The body 15 is subjected to the action of an elastic member (not shown) which tends to recall in this position. A flat cover 17 is pivotally mounted on the housing 7 by lateral L-shaped legs 18 having a segment parallel to the cover, the pivot axis being parallel to the upper face of the body 15 and passing at the free end of the legs 18. Closing this cover causes the body 15 to be pushed into the housing 7 and locked in the depressed position.

Sur les figures 5, 6, 7 on a représenté un troisième mode de réalisation du dispositif selon l'invention. Dans ce mode de réalisation, un écran de protection 20 est solidaire d'un corps allongé 21 dont une face constitue le bandeau de commande 11 d'une table de cuisson. Cet écran, qui s'étend le long de la partie arrière du corps 21 et est incliné d'environ 90° par rapport au bandeau de commande 11, est destiné à protéger ce dernier d'un écoulement de liquide dû au renversement ou au débordement d'une casserole. Le corps 21 est monté pivotant sur le boîtier 7 autour d'un axe parallèle au bord de la paroi avant du boîtier 7 et qui est sensiblement confondu avec le bord arrière de l'écran 20. Le corps 21 comprend un passage 22 s'étendant transversalement à l'écran 20, le long de cet écran,et débouchant d'une part dans le boîtier 7 et, d'autre part, au niveau du bord arrière du bandeau de commande 11. Le corps 21 est soumis à l'action d'un organe élastique associé à un ensemble de butées (non représentées) tendant à rappeler le corps 21 et l'écran 20 dans une des trois positions illustrées sur les figures 5, 6, 7. Dans la première position, (table de cuisson hors fonctionnement), l'écran 20 ferme le boîtier 7 et le bandeau de commande 11 n'est pas apparent. Dans la deuxième position (table de cuisson en fonctionnement), l'écran 20 est relevé au maximum, le bandeau de commande 11 est apparent et la partie avant du corps 21 est en butée contre la paroi avant du boîtier 7 : le passage 22 met alors en communication l'intérieur du boîtier 7 avec l'extérieur. Dans la troisième position (table de cuisson en fonctionnement), l'écran 20 occupe une position intermédiaire, la manipulation des moyens de commande n'est pas possible ; cependant la table de cuisson peut fonctionner, l'air de ventilation pouvant s'échapper du boîtier 7 selon les trajets représentés par les flèches. Cette troisième position assure une protection maximale au bandeau de commande 11 tandis qu'elle interdit la modification du réglage du chauffage des plaques.Figures 5, 6, 7 there is shown a third embodiment of the device according to the invention. In this embodiment, a protective screen 20 is secured to an elongated body 21, one face of which constitutes the control panel 11 of a hob. This screen, which extends along the rear part of the body 21 and is inclined by approximately 90 ° relative to the control panel 11, is intended to protect the latter from a flow of liquid due to spillage or overflow. of a pan. The body 21 is pivotally mounted on the housing 7 about an axis parallel to the edge of the front wall of the housing 7 and which is substantially coincident with the rear edge of the screen 20. The body 21 comprises a passage 22 extending transversely to the screen 20, along this screen, and opening on the one hand into the housing 7 and, on the other hand, at the rear edge of the control panel 11. The body 21 is subjected to the action of an elastic member associated with a set of stops (not shown) tending to return the body 21 and the screen 20 to one of the three positions illustrated in FIGS. 5, 6, 7. In the first position, (hob out of operation), the screen 20 closes the box 7 and the control panel 11 is not visible. In the second position (hob in operation), the screen 20 is raised to the maximum, the control panel 11 is visible and the front part of the body 21 is in abutment against the front wall of the housing 7: the passage 22 puts then in communication inside the box 7 with the outside. In the third position (hob in operation), the screen 20 occupies a intermediate position, manipulation of the control means is not possible; however, the hob can operate, the ventilation air being able to escape from the housing 7 along the paths represented by the arrows. This third position provides maximum protection to the control panel 11 while it prohibits the modification of the heating setting of the plates.

Comme le dispositif représenté sur les figures 1, 2, les dispositifs représentés respectivement sur les figures 3,4 et 5,6,7 peuvent être équipés d'un organe de sécurité coupant l'alimentation de la table de cuisson lorsque le couvercle 17 ou l'écran 20 sont rabattus dans le plan de la platine 4, c'est-à-dire lorsque l'orifice de sortie du circuit de ventilation est fermé.Like the device shown in Figures 1, 2, the devices shown in Figures 3,4 and 5,6,7 respectively can be fitted with a safety device cutting off the power to the hob when the cover 17 or the screen 20 is folded down in the plane of the plate 4, that is to say when the outlet orifice of the ventilation circuit is closed.

Le fonctionnement du dispositif de support des moyens de commande 10 associé à la table de cuisson 1, représentée sur la figure 1, est le suivant. Pour utiliser la table de cuisson, on bascule le corps 12 de façon à faire apparaître le bandeau de commande 11. L'interrupteur placé sur le circuit d'alimentation de la table de cuisson est alors fermé. Par la manipulation d'un des moyens de commande 10, on provoque à la fois la mise en marche du ventilateur 8 et l' échauffement de la plaque 5 correspondante. Le ventilateur 8 aspire de l'air dans le vide sanitaire 3 par l'ouverture d'aspiration 9. L'air pulsé par le ventilateur dans le boîtier 7 s'écoule le long des cartes de circuit électronique 6 puis, après s'être échauffé et avoir refroidi lesdites cartes, s'échappe par l'orifice de sortie constitué par l'extrémité du dégagement 13 du corps 10 ouvrant sur l'extérieur. Si, en cours de fonctionnement, le corps 12 était involontairement basculé en sens inverse, l'alimentation de la table de cuisson serait automatiquement coupée.The operation of the device for supporting the control means 10 associated with the hob 1, shown in FIG. 1, is as follows. To use the hob, the body 12 is tilted so as to reveal the control panel 11. The switch placed on the hob supply circuit is then closed. By manipulating one of the control means 10, both the fan 8 and the heating of the corresponding plate 5 are brought on. The fan 8 draws air into the crawl space 3 through the suction opening 9. The air blown by the fan into the housing 7 flows along the electronic circuit boards 6 then, after having heated and having cooled said cards, escapes through the outlet orifice formed by the end of the clearance 13 of the body 10 opening to the outside. If, during operation, the body 12 was involuntarily tilted in the opposite direction, the supply to the hob would be automatically cut off.
