Abstract

An electric oven has a number of heating elements for heating the cooking chamber. A multi-position switch is arranged to couple power to all of the heating elements, such that the chamber can be used as an oven, or to only selected heating elements such that a grilling operation can be performed. However, when grilling it is best if the door of the cooking chamber is at least partially open so that air can circulate. The invention provides a mechanical linkage between the door and the switch such that if the switch is moved into its grill operating position, the door is automatically opened. In addition, if the door of the cooking chamber is closed, the switch is automatically moved into its oven operating position.

Description

L'invention se rapporte aux fours ménagers électriques comprenant une enceinte de cuisson qui s'ouvre sur sa face frontale et qui contient une résistance chauffante de voûte et au moins une résistance chauffante de sole, un commutateur susceptible d'occuper soit une position "de fonctionnement en four" pour laquelle au moins la résistance de sole est alimentée, soit une position "de fonctionnement en gril" pour laquelle seule la résistance de voûte est alimentée, et une porte agencée sur ladite face frontale et adaptée à prendre, en particulier, soit une position fermée ou "de fonctionnement en four" pour laquelle elle est appliquée contre l'entourage de l'ouverture frontale, soit une position entrouverte ou "de fonctionnement en gril" pour laquelle elle laisse sur cette ouverture un espace de circulation d'air entre l'enceinte et l'extérieur.The invention relates to household electric ovens comprising a cooking enclosure which opens on its front face and which contains a heating element for the vault and at least one heating element for the bottom, a switch capable of occupying either a position "of oven operation "for which at least the hearth resistance is supplied, that is to say a" grill operation "position for which only the vault resistance is supplied, and a door arranged on said front face and adapted to take, in particular, either a closed or "operating in the oven" position for which it is applied against the surround of the front opening, or a half-open or "operating in the grill" position for which it leaves on this opening a circulation space for air between the enclosure and the exterior.

L'invention concerne, plus précisément les fours ménagers de ce genre qui comprennent en outre des organes de transmission de mouvement agencés entre le commutateur de commande des résistances et la porte et destinés à obtenir une corrélation automatique entre la position de la porte et le fonctionnement du commutateur.The invention relates more specifically to household ovens of this kind which further comprise movement transmission members arranged between the resistance control switch and the door and intended to obtain an automatic correlation between the position of the door and the operation of the switch.

Le brevet US - A - 4189632 décrit un four de ce genre dans lequel la porte, qui est normalement fermée pendant le fonctionnement en gril, s'entrouvre de façon automatique à la fin de ce fonctionnement en gril et commande l'arrêt simultané de l'alimentation des résistances. Cependant, un tel fonctionnement nuit à la qualité de l'opération de grillage qui ne peut être normalement menée à bien qu'avec une ventilation suffisante de l'aliment à griller pendant tout le temps du grillage. En outre, si l'usager omet d'ouvrir la porte, dès le début de l'opération de grillage, la résistance de voûte étant d'une puissance généralement élevée, provoque une élévation anormale de la température dans l'enceinte de cuisson, risquant d'endommager les parties constitutives de ce four, et de détruire le thermostat équipant l'appareil.US patent - A - 4189632 describes a furnace of this kind in which the door, which is normally closed during the operation in grill, opens automatically at the end of this operation in grill and controls the simultaneous stop of the resistor supply. However, such an operation is detrimental to the quality of the roasting operation which can normally only be carried out with sufficient ventilation of the food to be roasted during the entire time of the roasting. In addition, if the user fails to open the door, from the start of the toasting operation, the vault resistance being of generally high power, causes an abnormal rise in temperature in the cooking chamber, risking damage to the constituent parts of this oven, and destroying the thermostat fitted to the appliance.

L'invention a pour but d'apporter un perfectionnement à ce genre de four de manière à n'autoriser le fonctionnement en position gril, qu'avec la porte en position entrouverte, ceci afin d'éliminer les inconvénients décrits ci-dessus.The object of the invention is to provide an improvement to this kind of oven so as to allow operation in the grill position only with the door in the ajar position, in order to eliminate the drawbacks described above.

Selon l'invention, les organes de transmission de mouvement comprennent un entrebâilleur monté mobile sur l'entourage de l'ouverture frontale et lié mécaniquement à la commande du commutateur de telle manière que, lorsque le commutateur est en sa position de fonctionnement en four, l'entrebâilleur est en une position de repos pour laquelle il est escamoté et laisse ainsi la porte venir en sa position fermée, et que, lorsque le commutateur passe à sa position de fonctionnement en gril, l'entrebâilleur passe en une position active pour laquelle il s'interpose entre la porte et ledit entourage pour amener et maintenir cette porte en sa position entrouverte.According to the invention, the movement transmission members comprise a crank mounted movable on the surround of the front opening and mechanically linked to the control of the switch so that, when the switch is in its operating position in an oven, the spreader is in a rest position for which it is retracted and thus lets the door come into its closed position, and that, when the switch switches to its operating position on the grill, the spreader switches to an active position for which it is interposed between the door and said surround to bring and maintain this door in its ajar position.

Ainsi, grâce à cet arrangement des organes de transmission de mouvement, le four est transformé en gril et ceci de façon automatique, sans que l'usager ne se préoccupe lui-même de placer la porte en position entrouverte, l'entrebâilleur venant écarter la porte de l'entourage dès que l'usager fait passer le commutateur de sa position de fonctionnement en four à sa position de fonctionnement en gril.Thus, thanks to this arrangement of the motion transmission members, the oven is transformed into a grill and this automatically, without the user having to worry himself about placing the door in the half-open position, the ajar opening aside the entourage door as soon as the user switches the switch from its operating position in the oven to its operating position in the grill.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins annexés, dans lesquels:
la figure 1 représente en perspective un four ménager électrique auquel est appliquée l'invention; la figure 2 représente schématiquement ce four en coupe transversale verticale; la figure 3 est un schéma électrique du circuit d'alimentation des résistances chauffantes; la figure 4 représente en perspective, à grande échelle, les organes de transmission de mouvement agencés entre le commutateur de commande des résistances et la porte, pour la position de fonctionnement en four; la figure 5 est une vue analogue des mêmes organes pour la position de fonctionnement en gril.
The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended drawings, in which:
Figure 1 shows in perspective an electric household oven to which the invention is applied; Figure 2 schematically shows this oven in vertical cross section; Figure 3 is an electrical diagram of the supply circuit of the heating resistors; FIG. 4 shows in perspective, on a large scale, the movement transmission members arranged between the resistance control switch and the door, for the operating position in the oven; Figure 5 is a similar view of the same members for the grill operating position.

Le four représenté comprend une enceinte de cuisson 12 qui s'ouvre sur sa face frontale et qui contient une résistance chauffante de voûte 14 et deux résistances chauffantes de sole 16 et 18. Ces résistances sont commandées par un commutateur 20 (figures 3 à 5) qui est susceptible d'occuper, soit une position de fonctionnement en four (figure 4 et position A de la figure 3), soit une position de fonctionnement en gril (figure 5 et position B de la figure 3). Pour la position de fonctionnement en four, la résistance 16, d'une part, et l'ensemble des résistances 14 et 18 en série, d'autre part, sont alimentés en parallèle sur la tension du secteur appliquée aux bornes d'entrée 22 et 24. Pour la position de fonctionnement en gril, seule la résistance de voûte 14 est alimentée. Aussi bien en la position de fonctionnement en four qu'en la position de fonctionnement en gril, la tension d'alimentation est appliquée aux résistances à travers un interrupteur thermostatique 26 (dont une petite partie seulement est représentée aux figures 4 et 5) destiné à la régulation de la température de l'enceinte de cuisson lors du fonctionnement en four.The oven shown comprises a cooking chamber 12 which opens on its front face and which contains a heating resistance of the roof 14 and two heating elements of the bottom 16 and 18. These resistances are controlled by a switch 20 (FIGS. 3 to 5) which is likely to occupy either an operating position in the oven (Figure 4 and position A in Figure 3) or an operating position in the grill (Figure 5 and position B in Figure 3). For the oven operating position, the resistor 16, on the one hand, and all of the resistors 14 and 18 in series, on the other hand, are supplied in parallel on the mains voltage applied to the input terminals 22 and 24. For the grill operating position, only the top heater 14 is supplied. Both in the oven operating position and in the grill operating position, the supply voltage is applied to the resistors through a thermostatic switch 26 (only a small part of which is shown in FIGS. 4 and 5) intended to regulating the temperature of the cooking chamber during operation in the oven.

L'enceinte du cuisson 12 est équipée d'une porte 28 agencée sur la face frontale et articulée autour d'un axe horizontal 30 situé au voisinage de son bord inférieur. Cette porte peut prendre, en particulier, soit une position fermée (figures 2 et 4) pour laquelle elle est appliquée contre l'entourage 32 de l'ouverture frontale, soit une position entrouverte (figures 1 et 5) pour laquelle elle laisse sur cette ouverture un espace 34 de circulation d'air entre l'enceinte 12 et l'extérieur.The cooking chamber 12 is equipped with a door 28 arranged on the front face and articulated around a horizontal axis 30 located in the vicinity of its lower edge. This door can take, in particular, either a closed position (Figures 2 and 4) for which it is applied against the surround 32 of the front opening, or a half-open position (Figures 1 and 5) for which it leaves on this opening an air circulation space 34 between the enclosure 12 and the outside.

Le commutateur 20 de commande des résistances est actionné par une touche mobile 36. Cette touche est elle-même manoeuvrée par un arbre rotatif 38 qui est lui-même accouplé à l'arbre de réglage 40 de l'interrupteur thermostatique 26.The resistance control switch 20 is actuated by a movable key 36. This key is itself operated by a rotary shaft 38 which is itself coupled to the adjustment shaft 40 of the thermostatic switch 26.

L'arbre 38 est muni d'un bouton de manipulation 42 et porte une saillie latérale 44 qui, pour une position angulaire déterminée de cet arbre (fig.5), vient manoeuvrer la touche 36 du commutateur 20 pour amener ce commutateur en sa position de fonctionnement en gril (position B de la figure 3). Cette position correspond à une position angulaire du bouton 42 repérée par la lettre G, comme on le voit bien sur la figure 5, sur laquelle on a effectué un arrachement partiel de l'arbre 38 pour bien laisser voir la saillie 44. On notera qu'en même temps, l'arbre de réglage 40 assure, pour cette position, un blocage de l'interrupteur thermostatique 26 en une position de fermeture permanente de cet interrupteur.The shaft 38 is provided with a manipulation button 42 and carries a lateral projection 44 which, for a determined angular position of this shaft (fig.5), comes to operate the key 36 of the switch 20 to bring this switch to its position grill operation (position B in Figure 3). This position corresponds to an angular position of the button 42 identified by the letter G, as can be seen in FIG. 5, on which a partial cutout of the shaft 38 has been carried out in order to clearly show the projection 44. It will be noted that 'At the same time, the adjustment shaft 40 ensures, for this position, a blocking of the thermostatic switch 26 in a permanently closed position of this switch.

Pour toute position angulaire de réglage autre que ladite position déterminée repérée par la lettre G, la saillie 44 libère la touche 36 et laisse ainsi le commutateur 20 en sa position de fonctionnement en four (position A de la figure 3), l'interrupteur thermostatique 26 étant lui-même également libéré pour assurer la régulation de température en fonction du réglage choisi : ce choix s'effectue en faisant tourner le bouton 42 pour le placer en correspondance de l'un ou l'autre de repères chiffrés (par exemple 10 ou 9, tels que sur les figures 4 et 5).For any angular position of adjustment other than said determined position identified by the letter G, the projection 44 releases the key 36 and thus leaves the switch 20 in its operating position in the oven (position A in FIG. 3), the thermostatic switch. 26 being itself also released to ensure temperature regulation as a function of the chosen setting: this choice is made by turning the button 42 to place it in correspondence with one or the other of numerical marks (for example 10 or 9, as in Figures 4 and 5).

Des organes de transmission de mouvement, agencés entre le commutateur 20 et la porte 28, sont adaptés à assurer que le passage de ce commutateur de sa position de fonctionnement en four à sa position de fonctionnement en gril entraîne automatiquement le passage de la porte 28 de sa position fermée (figure 4) à sa position entrouverte (figure 5).Motion transmission members, arranged between the switch 20 and the door 28, are adapted to ensure that the passage of this switch from its operating position in the oven to its operating position in the grill automatically causes the passage of the door 28 from its closed position (Figure 4) to its half-open position (Figure 5).

Ces organes de transmission de mouvement comprennent un entrebâilleur 46 monté mobile sur l'entourage 32 de l'ouverture frontale et lié mécaniquement à l'arbre de commande 38 du commutateur 20 de telle manière que, lorsque ce commutateur est en sa position de fonctionnement en four (figure 4), l'entrebâilleur 46 est en une position de repos, pour laquelle il est escamoté pour laisser la porte 28 venir en sa position fermée, et que, lorsque ce commutateur passe à sa position de fonctionnement en gril (figure 5), l'entrebaîlleur 46 passe en une position active pour laquelle il s'interpose entre l'entourage 32 et le bord latéral 48 de la porte 28 pour amener cette porte à pivoter vers 1'extérieur jusqua'à sa position entrouverte et pour la maintenir en cette position.These motion transmission members comprise a stay 46 mounted movably on the surround 32 of the front opening and mechanically linked to the control shaft 38 of the switch 20 so that, when this switch is in its operating position in the oven (FIG. 4), the stay 46 is in a rest position, for which it is retracted to let the door 28 come to its closed position, and that, when this switch switches to its operating position in the grill (FIG. 5), the ajar 46 goes into an active position for which it is interposed between the surround 32 and the lateral edge 48 of the door 28 to cause this door to pivot outwards to its ajar position and to hold it there.

L'entrebaîlleur 46, comme on le voit sur les figures 4 et 5, est constitué par une crémaillère coulissante dont la denture 50 est en prise avec une roue dentée 52 solidaire de l'arbre rotatif 38 et dont une extrémité libre pointue porte une rampe inclinée 54 adaptée à s'engager entre le bord 48 de la porte 28 et l'entourage 32 lorsque la crémaillère passe en sa position active.The ajar 46, as can be seen in FIGS. 4 and 5, is constituted by a sliding rack whose teeth 50 are engaged with a toothed wheel 52 secured to the rotary shaft 38 and whose pointed free end carries a ramp inclined 54 adapted to engage between the edge 48 of the door 28 and the surround 32 when the rack moves into its active position.

Si l'usager, alors que le commutateur 20 est en sa position de fonctionnement en gril (figure 5), exerce sur la porte 28 une poussée (fléche F) tendant à la faire passer de sa position entrouverte à sa position fermée, le bord 48 de cette porte coopère avec la rampe inclinée 54 pour ramener la crémaillère 46 à sa position de repos (fléche H) et entraîner ainsi une rotation de l'arbre 38 (fléche J) propre à faire passer le commutateur 20 de sa position de fonctionnement en gril à sa position de fonctionnement en four(repère 10).If the user, while the switch 20 is in its grill operating position (FIG. 5), exerts on the door 28 a push (arrow F) tending to cause it to pass from its half-open position to its closed position, the edge 48 of this door cooperates with the inclined ramp 54 to return the rack 46 to its rest position (arrow H) and thus cause a rotation of the shaft 38 (arrow J) suitable for passing the switch 20 from its operating position on the grill in its oven operating position (item 10).

Ainsi, les organes de transmission agencés entre le commutateur 20 et la porte 28, et constitués par l'arbre 38, la roue dentée 52, la crémaillère 46, et la rampe 54, sont adaptés à assurer, non seulement que le passage du commutateur 20 à sa position de fonctionnement en gril entraîne le passage de la porte en sa position entrouverte, mais encore, inversement, que le retour de la porte vers sa position fermée entraîne le passage du commutateur 20 en sa position de fonctionnement en four.Thus, the transmission members arranged between the switch 20 and the door 28, and constituted by the shaft 38, the toothed wheel 52, the rack 46, and the ramp 54, are adapted to ensure, not only that the passage of the switch 20 in its grill operating position causes the door to pass into its ajar position, but again, conversely, that the return of the door to its closed position causes the switch 20 to pass into its operating position in the oven.

L'usager n'a donc pas à se préoccuper de placer la porte 28 en position convenable pour le fonctionnement en gril, puisque cette opération se fait automatiquement. Il n'a pas non plus à se préoccuper de manipuler le bouton 42 lorsqu'il souhaite revenir à la position de fonctionnement en four, puisque cette opération s'effectue, elle aussi, automatiquement.The user therefore does not have to worry about placing the door 28 in a position suitable for grill operation, since this operation is done automatically. He also does not have to worry about manipulating the button 42 when he wishes to return to the operating position in the oven, since this operation is also carried out automatically.

A domestic oven according to Claim 2, characterized in that the rotatable control spindle (38) being coupled to the regulating spindle (40) of a thermostat switch (26) for regulating the temperature of the cooking compartment (12), this control spindle (38) comprises a lateral projection (44) which, in a predetermined angular position of this spindle, actuates the switch (20) to bring it into its position for grill operation, and at the same time ensures that the thermostat switch (26) is permanently closed, whereas in any angular control position other than the said predetermined position, the switch (20) is left in its position for oven operation, the thermostat switch (26) also being set free in order to provide the said regulation of temperature depending on the control setting selected.
  4. A domestic oven according to any one of the preceding Claims, characterized in that the elements for transmitting movement (38, 52, 46, 54) located between the switch (20) and the door (28) are also adapted to ensure that the movement of the door (28) from its partially open position to its closed position automatically entrains the movement of the switch (20) from its position for grill operation to its position for oven operation.
  5. A domestic oven according to Claims 3 and 4, characterized in that during the movement of the door (28) from its partially open position to its closed position, the edge (48) of this door cooperates with the inclined ramp (54) to return the rack (46) to its resting position and thus to cause the movement of the switch (20) from its position for grill operation to its position for oven operation.
