Description

APPAREIL ELECTRIQUE DE CUISSON, NOTAMMENT FRITEUSE ELECTRIC COOKING APPLIANCE, ESPECIALLY A FRYER
La présente invention se rapporte aux appareils électriques de cuisson, notamment mais non exclusivement aux friteuses électriques destinées à la cuisson, dans un bain d'huile en particulier, d'aliments tels que des frites, des poissons ou de la viande, et comportant, dans un boîtier, une cuve métallique et un élément de chauffage rapporté extérieurement sur le fond de la cuve.The present invention relates to electric cooking appliances, in particular but not exclusively to electric fryers intended for cooking, in a particular oil bath, of foods such as fries, fish or meat, and comprising, in a housing, a metal tank and a heating element attached externally to the bottom of the tank.
Lors de l'utilisation d'un tel appareil de cuisson, par exemple une friteuse, il existe toujours le risque que l'utilisateur oublie de remplir d'huile la cuve et déclenche l'opération de friture, conduisant alors rapi- dément à un endom agement de la cuve, tel qu'une fissuration du revêtement, par exemple un émail, qui est généralement utilisé pour faciliter le nettoyage de la cuve et qui recouvre intérieurement et extérieurement cette dernière, voire même à une inflammation de la friteuse due à la présence d'un film d'huile résiduel sur les parois internes de la cuve.When using such a cooking appliance, for example a fryer, there is always the risk that the user forgets to fill the tank with oil and starts the frying operation, leading quickly to a damage to the tank, such as cracking of the coating, for example an enamel, which is generally used to facilitate cleaning of the tank and which covers the latter internally and externally, or even to an inflammation of the fryer due to the presence of a film of residual oil on the internal walls of the tank.
L'invention a notamment pour but de pallier ces inconvénients et de réaliser de manière simple et peu coû- teuse un appareil électrique de cuisson, du type exposé ci-dessus, qui présente une grande sécurité de fonctionnement à l'égard -de tout risque lié à l'absence d'huile ou à la trop faible quantité d'huile dans la cuve.The object of the invention is in particular to alleviate these drawbacks and to produce in an simple and inexpensive manner an electric cooking appliance, of the type described above, which has great operational safety with regard to any risk. linked to the absence of oil or to the insufficient quantity of oil in the tank.
Selon l'invention, l'appareil comporte en outre un bilame disposé en contact thermique direct avec l'élément de chauffage, et deplaçable en réponse à un excès de chaleur produit par l'élément de chauffage lors du fonctionnement de l'appareil et correspondant à une cuve sensi- blement vide, pour venir occuper une position active dans laquelle il commande l'ouverture du circuit d'alimentation électrique de l'élément de chauffage.According to the invention, the apparatus further comprises a bimetallic strip arranged in direct thermal contact with the heating element, and displaceable in response to an excess of heat produced by the heating element during operation of the apparatus and corresponding to a substantially empty tank, to come and occupy an active position in which it controls the opening of the electrical supply circuit of the heating element.
On entend par excès de chaleur un échauffement de l'élément de chauffage se produisant pour une température de cet élément qui excède une température maximale prédéfinie représentative d'une cuve vide d'huile ou insuffisamment remplie d'huile.By excess heat is meant heating of the heating element occurring for a temperature of this element which exceeds a predefined maximum temperature representative of a tank empty of oil or insufficiently filled with oil.
Ainsi, le bilame étant disposé en parfaite condition d'échange de chaleur avec l'élément de chauffage, on comprend que tout échauffement excessif de cet élément provoque un déplacement du bilame en vue de couper rapidement le chauffage lorsque la cuve est vide d'huile ou est insuffisamment remplie d'huile, offrant ainsi une garantie optimale de sécurité à l'utilisateur. En outre, le bilame constitue un organe sensible à la température qui est en soi simple, peu coûteux et fiable.Thus, the bimetallic strip being arranged in perfect heat exchange condition with the heating element, it is understood that any excessive heating of this element causes a displacement of the bimetallic strip in order to quickly cut the heating when the tank is empty of oil or is insufficiently filled with oil, thus providing an optimal guarantee of safety for the user. In addition, the bimetallic strip constitutes a body sensitive to temperature which is in itself simple, inexpensive and reliable.
Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :The characteristics and advantages of the invention will become apparent from the description which follows, by way of nonlimiting example, with reference to the appended drawings in which:
- la figure 1 est une vue schématique partielle en coupe verticale d'un appareil de cuisson, tel qu'une friteuse, en fonctionnement normal ; et- Figure 1 is a partial schematic view in vertical section of a cooking appliance, such as a fryer, in normal operation; and
- la figure 2 est une vue similaire à la figure 1, pour une cuve vide d'huile.- Figure 2 is a view similar to Figure 1, for an empty oil tank.
Dans l'exemple de réalisation illustré à la figure 1, la friteuse électrique comporte un boîtier externe 1 représenté ici schématiquement en traits mixtes, qui délimite une enceinte fermée grâce à un couvercle (non représenté) , et à l'intérieur duquel est disposée une cuve métallique 2, par exemple de forme rectangulaire, pourvue extérieurement sur son fond 4 d'un élément de chauffage électrique 5, adapté à chauffer la cuve et constitué par exemple par une résistance blindée qui est rapportée sur la face externe 4a du fond 4 de la cuve par tout moyen de fixation approprié, par exemple par soudure.In the embodiment illustrated in FIG. 1, the electric fryer comprises an external box 1 shown here schematically in phantom, which delimits an enclosure closed by a cover (not shown), and inside which is arranged a metal tank 2, for example of rectangular shape, provided externally on its bottom 4 of an electric heating element 5, suitable for heating the tank and constituted for example by an armored resistance which is attached to the external face 4a of the bottom 4 of the tank by any suitable fixing means, for example by welding.
Dans cet exemple, la cuve 2 munie de la résistance de chauffage 5 est montée fixe, d'une manière connue en soi, dans le boîtier 1.In this example, the tank 2 provided with the heating resistor 5 is mounted fixed, in a manner known per se, in the housing 1.
Bien entendu, la cuve 2 pourvue de la résistance de chauffage 5 peut également être montée amovible dans le boîtier 1, sans sortir pour cela du cadre de l'invention.Of course, the tank 2 provided with the heating resistor 5 can also be removably mounted in the housing 1, without thereby departing from the scope of the invention.
La cuve 2, présente dans le boîtier 1, est destinée à contenir un bain d'huile 7 pour la cuisson par immersion d'aliments, tels que par exemple des frites 8, contenus dans un panier de friture 9, comme illustré à la figure 1.The tank 2, present in the housing 1, is intended to contain an oil bath 7 for cooking by immersion of food, such as for example fries 8, contained in a frying basket 9, as illustrated in the figure 1.
Avantageusement, la cuve 2 est réalisée par emboutissage d'une plaque de tôle, par exemple en acier, et est ensuite recouverte intérieurement et extérieurement d'un revêtement résistant à la chaleur, par exemple de l'émail, qui permet de faciliter le nettoyage de la cuve et d'éviter l'adhérence des aliments sur la surface inté¬ rieure de la cuve.,Advantageously, the tank 2 is produced by stamping a sheet metal plate, for example of steel, and is then covered internally and externally with a heat-resistant coating, for example enamel, which makes cleaning easier. of the vessel and to avoid adhesion of food on the Internal Surface ¬ higher of the vessel.,
La résistance blindée de chauffage 5 présente par exemple une section droite triangulaire, comme visible aux figures 1 et 2, et est conformée avantageusement en un serpentin permettant de favoriser son contact thermique sur toute la longueur et toute la largeur du fond 4 de la cuve 2 rectangulaire dans cet exemple. Selon 1 ' invention, la f iteuse électrique comporte de plus un bilame 11 disposé en contact thermique direct avec la résistance de chauffage 5 et deplaçable en ré- ponse à un échauffement excessif de la résistance 5 se produisant lors du fonctionnement de la friteuse et correspondant à une cuve 2 sensiblement vide d'huile (figure 2), de manière à venir occuper une position active, telle qu'illustrée à la figure 2, dans laquelle il commande l'ouverture du circuit d'alimentation électrique de la résistance de chauffage 5.The armored heating resistor 5 has for example a triangular cross section, as visible in FIGS. 1 and 2, and is advantageously shaped as a coil making it possible to promote its thermal contact over the entire length and the entire width of the bottom 4 of the tank 2 rectangular in this example. According to the invention, the electric fryer further comprises a bimetallic strip 11 disposed in direct thermal contact with the heating resistor 5 and displaceable in response to an excessive heating of the resistor 5 occurring during the operation of the fryer and corresponding to a tank 2 substantially empty of oil (Figure 2), so as to come to occupy an active position, as illustrated in Figure 2, in which it controls the opening of the electrical supply circuit of the heating resistor 5.
Dans l'exemple de réalisation représenté sur la figure 1, le bilame 11 présente une forme générale approxi- mativement rectangulaire allongée s ' étendant à plat en dessous de la résistance de chauffage 5, suivant une direction sensiblement parallèle à la largeur de la cuve 2. Dans cet exemple, le bilame 11 comporte une première extrémité libre 13, légèrement incurvée vers le haut, qui est en appui ponctuel, noté P sur la figure 1, contre un tronçon de la résistance de chauffage 5, et une seconde extrémité 15 qui est montée pivotante sur le corps 17 d'un interrupteur de sécurité 19 agencé dans le circuit d'alimentation électrique de la résistance de chauffage 5.In the embodiment shown in FIG. 1, the bimetallic strip 11 has a generally elongated, approximately rectangular shape extending flat below the heating resistor 5, in a direction substantially parallel to the width of the tank 2 In this example, the bimetallic strip 11 has a first free end 13, slightly curved upwards, which is in point contact, denoted P in FIG. 1, against a section of the heating resistor 5, and a second end 15 which is pivotally mounted on the body 17 of a safety switch 19 arranged in the electrical supply circuit of the heating resistor 5.
Dans ce mode, de réalisation, l'interrupteur de sécurité 19 est du type normalement ouvert et comporte un bouton de commande mobile 20, associé à un ressort de rappel 22, dont 1 ' actionnement est subordonné au pivotement du bilame 11 et dont l'enfoncement ferme les contacts ; cet interrupteur 19 présente des connexions électriques 23, 24 destinées à être reliées au circuit d'alimentation électrique de la résistance de chauffage 5. Ce montage direct du bilame 11 sur le corps de l'interrupteur de sécurité 19 permet avantageusement d'obtenir un dispositif de sécurité qui est particulière- ment compact et peu encombrant au sein de la friteuse. De plus, le bilame 11 fait également office, d'une manière avantageuse, d'organe de commande de l'ouverture et de la fermeture de l'interrupteur 19.In this embodiment, the safety switch 19 is of the normally open type and comprises a movable control button 20, associated with a return spring 22, the actuation of which is subject to the pivoting of the bimetallic strip 11 and the pressing closes the contacts; this switch 19 has electrical connections 23, 24 intended to be connected to the electrical supply circuit of the heating resistor 5. This direct mounting of the bimetallic strip 11 on the body of the safety switch 19 advantageously makes it possible to obtain a safety device which is particularly compact and space-saving within the fryer. In addition, the bimetallic strip 11 also acts, advantageously, as a control member for the opening and closing of the switch 19.
En fonctionnement normal de la friteuse, c'est-à- dire lorsque la cuve 2 est suffisamment remplie d'huile, et après plongée dans le bain d'huile du panier de friture 9 contenant les aliments à frire, comme illustré à la figure 1, le bilame 11 occupe une position de repos dans laquelle il prend appui par son extrémité libre 13 sur la résistance de chauffage 5 et maintient enfoncé le bouton 20 de l'interrupteur 19, à 1 ' encontre du ressort de rappel 22, lequel interrupteur 19 est à l'état fermé et autorise le passage du courant dans le circuit d'ali- mentation électrique de la résistance de chauffage 5. La température de la résistance 5 restant inférieure à une température maximale admissible, le bilame 11 ne s'échauffe pas suffisamment pour pouvoir se déformer.In normal operation of the fryer, that is to say when the tank 2 is sufficiently filled with oil, and after immersion in the oil bath of the frying basket 9 containing the food to be fried, as illustrated in the figure 1, the bimetallic strip 11 occupies a rest position in which it bears by its free end 13 on the heating resistor 5 and holds down the button 20 of the switch 19, against the return spring 22, which switch 19 is in the closed state and authorizes the passage of current in the electrical supply circuit of the heating resistor 5. The temperature of the resistor 5 remaining below a maximum admissible temperature, the bimetallic strip 11 does not heat up not enough to be able to deform.
Si maintenant la cuve 2 est vide ou insuffisamment remplie d'huile, comme illustré à la figure 2, la tempé¬ rature de la résistance 5 augmente rapidement pour dépasser la température maximale admissible, provoquant alors par échange de chaleur une déformation appropriée de l'extrémité libre 13 du bilame 11 ; par suite de cette déformation, le bilame 11 bascule en sens antihoraire pour venir occuper sa position active (figure 2) dans laquelle il libère le bouton 20 de l'interrupteur 19, lequel bouton 20 remonte sous l'action de son ressort de rappel 22 et provoque l'ouverture de l'interrupteur 19, permettant ainsi la coupure rapide par cyclage du chauffage de la résistance 5. Comme le montre la figure 2, l'extrémité libre 13 du bilame 11 reste en appui ponctuel, noté Q sur cette figure 2, lorsque le bilame occupe sa position active.If now the tank 2 is empty or not sufficiently filled with oil, as shown in Figure 2, the tem perature ¬ the resistor 5 rapidly increases to exceed the maximum allowable temperature, thus causing heat exchange by a suitable deformation of the free end 13 of bimetallic strip 11; as a result of this deformation, the bimetallic strip 11 swings counterclockwise to come to occupy its active position (FIG. 2) in which it releases the button 20 from the switch 19, which button 20 goes back up under the action of its return spring 22 and causes the switch 19 to open, thus allowing rapid cut-off by heating cycle of the resistor 5. As shown in FIG. 2, the free end 13 of the bimetallic strip 11 remains in point contact, noted Q in this FIG. 2, when the bimetallic strip occupies its active position.
On indiquera que dans le cas d'une cuve amovible portant la résistance de chauffage 5, la mise en place de la cuve dans le boîtier 1 provoque, par appui mécanique de la résistance 5 sur l'extrémité libre 13 du bilame 11, un basculement du bilame 11 vers sa position de repos, telle qu'illustrée à la figure 1, dans laquelle le bilame permet la fermeture du circuit d'alimentation électrique de la résistance de chauffage 5. It will be indicated that in the case of a removable tank carrying the heating resistor 5, the positioning of the tank in the housing 1 causes, by mechanical support of the resistor 5 on the free end 13 of the bimetallic strip 11, a tilting from the bimetallic strip 11 to its rest position, as illustrated in FIG. 1, in which the bimetallic strip allows the electrical supply circuit of the heating resistor 5 to be closed.
