Description

L'invention se rapporte au montage d'un capteur dans une table de cuissonThe invention relates to mounting a sensor in a table Cooking

Dans une table de cuisson, il est connu d'utiliser un capteur de température pour mesurer la température d'un ustensile de cuisine chauffé par un foyer appartenant à la table de cuisson. La mesure de la température de l'ustensile peut par exemple être utilisée pour asservir la puissance de chauffe délivrée par le foyer à l'ustensile de cuisine.In a hob, it is known to use a temperature to measure the temperature of a heated kitchen utensil by a hearth belonging to the hob. Temperature measurement utensil can for example be used to control the power of heater delivered by the fireplace to the kitchen utensil.

Il est connu de monter dans une table de cuisson un capteur de température au-dessus d'un foyer de, cuisson. Le montage se fait par exemple, soit au travers, soit au-dessous d'une plaque d'âtre qui recouvre le foyer. Généralement, le foyer est circulaire et le capteur de température est situé sensiblement au-dessus du centre du foyer. Le capteur est relié à des moyens de traitement de la mesure de température par une liaison par exemple électrique. Cette liaison traverse le foyer sensiblement en son centre. Le fait de traverser le foyer entraíne une difficulté de montage de la table de cuisson. En effet, lorsque le foyer est posé au fond de la table de cuisson et que l'on souhaite poser la plaque d'âtre munie de son capteur au-dessus du foyer, le montage de la liaison au travers du foyer est gêné par la plaque d'âtre qui masque le foyer.It is known to mount a sensor in a hob. temperature above a cooking hearth. The assembly is done by example, either through or below a hearth plate covering the foyer. Generally, the hearth is circular and the temperature sensor is located substantially above the center of the hearth. The sensor is connected to means for processing the temperature measurement by a link by electrical example. This connection crosses the hearth substantially in its center. The fact of crossing the hearth causes a difficulty in mounting the Cooktop. When the fireplace is placed at the bottom of the table cooking and you want to place the hearth plate with its sensor above of the hearth, the mounting of the connection through the hearth is hindered by the hearth plate which masks the hearth.

L'invention a pour but de pallier cette difficulté en proposant un montage de la liaison ne traversant pas le foyer. Pour atteindre ce but, l'invention a pour objet, une table de cuisson comportant une plaque d'âtre, un foyer de cuisson situé sous la plaque d'âtre, la plaque d'âtre étant destinée à supporter un ustensile de cuisine chauffé par le foyer de cuisson, un capteur fixé à la plaque d'âtre, une liaison entre le capteur et des moyens de traitement, caractérisée en ce que la liaison est disposée entre le foyer de cuisson et la plaque d'âtre, et s'étend au-delà du foyer de cuisson .The object of the invention is to overcome this difficulty by proposing a mounting of the link not crossing the hearth. To reach this goal, the subject of the invention is a hob comprising a hearth plate, a cooking hearth located under the hearth plate, the hearth plate being intended to support a kitchen utensil heated by the cooking stove, a sensor fixed to the hearth plate, a connection between the sensor and means treatment, characterized in that the connection is arranged between the focal point of and the hearth plate, and extends beyond the cooking zone.

L'invention est avantageusement mise en oeuvre avec un foyer à induction. En effet, ce type de foyer chauffe directement l'ustensile de cuisine posé sur la plaque d'âtre, sans chauffer la liaison entre le capteur et les moyens de traitement. D'autres types de foyers imposeraient une liaison résistant à plus haute température, ce qui augmenterait le coût de réalisation de la table de cuisson.The invention is advantageously implemented with a induction. Indeed, this type of hearth directly heats the cookware kitchen placed on the hearth plate, without heating the connection between the collector and the means of treatment. Other types of households would require a bond resistant to higher temperature, which would increase the cost of production from the hob.

L'invention sera mieux comprise et d'autres avantages apparaítront à la lecture de la description ci-après illustrée par le dessin joint dans lequel :

  • la figure 1 représente une table de cuisson, conforme à l'invention, dans laquelle le capteur de température est maintenu au contact de l'ustensile de cuisine au moyen d'un palpeur à ressort ;
  • la figure 2 représente une table de cuisson, conforme à l'invention, dans laquelle le capteur de température comporte une zone sensible maintenue en position fixe sur la plaque d'âtre.
The invention will be better understood and other advantages will appear on reading the description below illustrated by the attached drawing in which:
  • Figure 1 shows a hob, according to the invention, in which the temperature sensor is held in contact with the kitchen utensil by means of a spring probe;
  • FIG. 2 represents a hob, according to the invention, in which the temperature sensor comprises a sensitive zone maintained in a fixed position on the hearth plate.

Pour plus de clarté, on utilisera dans les différentes figures les mêmes repères topologiques pour désigner les mêmes éléments.For clarity, we will use in the different figures the same topological references to designate the same elements.

Les modes de réalisation de l'invention sont décrit ci-après, en rapport au montage d'un capteur de température. Il est bien entendu que l'invention peut être mise en oeuvre quelque soit le type de capteur fixé sur une plaque d'âtre et pour lequel on souhaite éviter que les fils de liaison vers des moyens de traitement ne traversent le foyer.The embodiments of the invention are described below, in compared to the installation of a temperature sensor. It is understood that the invention can be implemented whatever the type of sensor fixed on a hearth plate and for which one wishes to avoid that the connecting wires to treatment means do not pass through the hearth.

La table de cuisson représentée figure 1 comporte une plaque d'âtre 1 et un foyer de cuisson 2 situé sous la plaque d'âtre 1. Le foyer de cuisson 2 est sensiblement circulaire d'axe 3. L'axe 3 est sensiblement perpendiculaire à la plaque d'âtre 1. Le foyer de cuisson 2 a sensiblement la forme d'une rondelle plate. Il est bien entendu que d'autre formes de foyer de cuisson 2 sont possibles pour mettre en oeuvre l'invention. Le foyer de cuisson 2 comporte un trou 4 sensiblement d'axe 3. Certains matériaux utilisés pour réaliser la plaque d'âtre 1, comme par exemple de la vitrocéramique ne sont pas de bons isolants électriques à haute température. Il est donc nécessaire d'isoler électriquement le foyer de cuisson 2 de la plaque d'âtre 1. On peut utiliser de l'air pour réaliser cette isolation mais avantageusement on dispose entre le foyer de cuisson 2 et la plaque d'âtre 1 un isolant électrique 5. L'isolant électrique 5 recouvre sensiblement le foyer 2. La table de cuisson comporte également un capteur de température 6. Le capteur de température 6 est destiné à mesurer la température d'un ustensile de cuisine posé sur la plaque d'âtre 1, au-dessus du foyer de cuisson 2. Le capteur de température 6 est sensiblement situé sur l'axe 3. Le capteur de température 6 comporte une partie fixe 7 fixée à la plaque d'âtre 1. Le capteur de température 6 comporte également une partie mobile 8 suivant l'axe 3. Un ressort 9 maintient à distance la partie mobile 8 de la partie fixe 7. En l'absence d'ustensile de cuisine, la distance entre la partie mobile 8 et la partie fixe 7 est telle que la partie mobile 8 soit située au-dessus de la face supérieure 10 de la plaque d'âtre 1. En revanche, lorsqu'un ustensile de cuisine est posé sur la plaque d'âtre 1, l'ustensile de cuisine appuie sur la partie mobile 8. Le ressort 9 tend à maintenir la partie mobile 8 en contact avec l'ustensile de cuisine. La partie mobile 8 forme une zone sensible du capteur de température 6. Le capteur de température 6 comporte également un composant 11 permettant de mesurer la température. Le composant 11 est par exemple une résistance à coefficient de température positif ou négatif. Le composant 11 peut aussi être réalisé au moyen d'un thermocouple. Le composant 11 doit être fixé au plus près de la zone sensible 8. La table de cuisson comporte des moyens de traitement 12. Le capteur de température 6 est relié aux moyens de traitement 12 par une liaison 13. La liaison 13 est disposée entre le foyer de cuisson 2 et la plaque d'âtre 1, et s'étend au-delà du foyer de cuisson 2. Avantageusement, la liaison 13 est disposée au-dessus de l'isolant électrique 5.The hob shown in Figure 1 has a plate hearth 1 and a cooking hearth 2 located under the hearth plate 1. The hearth of firing 2 is substantially circular with axis 3. Axis 3 is substantially perpendicular to the hearth plate 1. The cooking hearth 2 has substantially the shaped like a flat washer. It is understood that other forms of focus cooking 2 are possible to implement the invention. The home of cooking 2 has a hole 4 substantially on axis 3. Certain materials used to make the hearth plate 1, such as for example glass ceramics are not good high electrical insulators temperature. It is therefore necessary to electrically isolate the hearth from cooking 2 of the hearth plate 1. Air can be used to achieve this insulation but advantageously there is between the cooking hearth 2 and the hearth plate 1 an electrical insulator 5. The electrical insulator 5 covers substantially the hearth 2. The hob also includes a sensor temperature sensor 6. The temperature sensor 6 is intended to measure the temperature of a kitchen utensil placed on the hearth plate 1, above of the cooking hearth 2. The temperature sensor 6 is substantially located on the axis 3. The temperature sensor 6 has a fixed part 7 fixed to the hearth plate 1. The temperature sensor 6 also includes a part movable 8 along the axis 3. A spring 9 keeps the movable part 8 at a distance of the fixed part 7. In the absence of kitchen utensil, the distance between the mobile part 8 and the fixed part 7 is such that the mobile part 8 is located above the upper face 10 of the hearth plate 1. On the other hand, when a kitchen utensil is placed on the hearth plate 1, the cookware kitchen presses on the moving part 8. The spring 9 tends to hold the part mobile 8 in contact with the kitchen utensil. The movable part 8 forms a sensitive area of the temperature sensor 6. The temperature sensor 6 also includes a component 11 for measuring the temperature. Component 11 is for example a coefficient resistance positive or negative temperature. Component 11 can also be produced at using a thermocouple. Component 11 must be fixed as close as possible to the sensitive zone 8. The hob has processing means 12. The temperature sensor 6 is connected to the processing means 12 by a link 13. The link 13 is arranged between the cooking hearth 2 and the plate hearth 1, and extends beyond the cooking hearth 2. Advantageously, the link 13 is arranged above the electrical insulator 5.

Le positionnement de la liaison 13 au-dessus de l'isolant électrique 5 permet de réduire l'isolation électrique de la liaison 13 par rapport à son environnement. Ceci représente un avantage par rapport aux réalisations connues qui nécessitent une isolation électrique de la liaison 13 par rapport au foyer de cuisson 2 lorsque celle-ci traverse le foyer de cuisson 2.Positioning of the connection 13 above the insulation electrical 5 reduces the electrical insulation of the connection 13 by in relation to its environment. This is an advantage over known embodiments which require electrical insulation of the connection 13 with respect to cooking hearth 2 when this crosses the cooking hearth cooking 2.

Les moyens de traitement 12 peuvent également alimenter le foyer de cuisson 2 en énergie. Les moyens de traitement 12 sont alors reliés à une alimentation 14 extérieure à la table de cuisson. Les moyens de traitement 12 peuvent par exemple asservir l'alimentation du foyer de cuisson 2 en fonction de la température mesurée par le capteur de température 6.The processing means 12 can also supply the cooking stove 2 in energy. The processing means 12 are then connected to a power supply 14 outside the hob. The means of treatment 12 can for example enslave the supply of the household cooking 2 as a function of the temperature measured by the temperature 6.

La table de cuisson représentée figure 2 comporte la plaque d'âtre 1, le foyer de cuisson 2, l'isolant électrique 5, le capteur de température 6 et les moyens de traitement 12, tous disposés comme à la figure 1. A la différence de la figure 1 le capteur de température 6 ne comporte pas de partie mobile. Le capteur de température 6 comporte une zone sensible 20 maintenue en position fixe sur la plaque d'âtre 1. La zone sensible 20 est par exemple réalisée au moyen d'une pastille métallique immobilisée contre la face supérieure 21 de la plaque d'âtre 1. La plaque d'âtre 1 comporte un trou 22 contenant le composant 11. Le trou 22 est obturé de façon étanche par la zone sensible 20. Le capteur de température 6 peut également être noyé dans la plaque d'âtre, lorsque celle-ci est réalisé par exemple par moulage. La zone sensible 20 peut également avoir toute autre forme comme par exemple la forme d'une bille. La zone sensible 20 peut être située légèrement au-dessus ou au-dessous de la face supérieure 21 de la plaque d'âtre 1. La variante représentée figure 2 présente l'avantage de ne pas comporter de pièce mobile. En effet, les pièces mobiles de ce type de montage le rendent compliqué à réaliser et la température élevée à laquelle il est soumis peut entraíner des phénomènes de grippage, l'empêchant de fonctionner correctement. De plus, ce type de montage n'est pas étanche et est difficile à nettoyer.The hob shown in Figure 2 has the plate hearth 1, the cooking hearth 2, the electrical insulation 5, the temperature 6 and the processing means 12, all arranged as at figure 1. Unlike figure 1 the temperature sensor 6 does not has no moving part. The temperature sensor 6 has a sensitive zone 20 maintained in a fixed position on the hearth plate 1. The zone sensitive 20 is for example made by means of a metal pad immobilized against the upper face 21 of the hearth plate 1. The plate hearth 1 has a hole 22 containing the component 11. The hole 22 is sealed in the sensitive area 20. The temperature sensor 6 can also be embedded in the hearth plate, when the latter is produced for example by molding. The sensitive zone 20 can also have any other shape such as for example the shape of a ball. The sensitive area 20 can be located slightly above or below the top 21 of the hearth plate 1. The variant shown in FIG. 2 presents the advantage of not having a moving part. Indeed, moving parts of this type of assembly make it complicated to perform and the temperature high to which it is subjected can cause seizure phenomena, preventing it from functioning properly. In addition, this type of mounting is not not waterproof and difficult to clean.

Lorsque le foyer de cuisson 2 est un foyer à induction, le composant 11 est avantageusement un thermocouple. En effet, le thermocouple comporte une impédance plus basse que les résistances à coefficient de température. Ainsi le signal issu du composant 11 risque moins d'être perturbée par le champ magnétique délivré par le foyer de cuisson 2. Dans ce mode de réalisation, le foyer est avantageusement un foyer à induction. En effet, le foyer de cuisson 2 chauffe directement un ustensile de cuisine posé sur la plaque d'âtre 1 sans chauffer la liaison 13. D'autres types de foyers imposeraient une liaison 13 résistant à haute température ; ce qui augmenterait le coût de réalisation de la table de cuisson.When the cooking zone 2 is an induction zone, the component 11 is advantageously a thermocouple. Indeed, the thermocouple has a lower impedance than the resistors temperature coefficient. So the signal from component 11 risks less disturbed by the magnetic field delivered by the focus of cooking 2. In this embodiment, the hearth is advantageously a induction fireplace. Indeed, the cooking hearth 2 directly heats a kitchen utensil placed on the hearth plate 1 without heating the connection 13. Other types of outbreaks would require a high-resistance bond 13 temperature ; which would increase the cost of making the table cooking.
