Description

La présente invention concerne l'affichage des séquences et/ou de la température d'un appareil de cuisson.The present invention relates to the display of the sequences and / or the temperature of a cooking appliance.

Les appareils de cuisson modernes comportent généralement plusieurs séquences de fonctionnement définies par la mise sous tension sélective des différentes résistances de sol ou de plafond et éventuellement d'un ventilateur, chaque séquence présentant une température réglable.Modern cooking appliances generally comprise several operating sequences defined by the selective energization of the different floor or ceiling resistances and possibly a fan, each sequence having an adjustable temperature.

Les différentes séquences, connues, sous une appellation commune à tous les constructeurs, font chacune l'objet d'un affichage sur le bandeau d'un appareil et d'une sélection par un commutateur de puissance.The different sequences, known, under a name common to all manufacturers, are each displayed on the banner of a device and selected by a power switch.

De manière connue, les différents affichages correspondant chacun à une séquence, sont réalisés par un dispositif à voyants lumineux alignés le long du bandeau. L'allumage de chaque voyant est obtenu à l'aide d'une ampoule portée par une chaîne tendue entre deux pignons dont un, dit d'entraînement, est situé dans l'axe du commutateur de puissance et manceuvré, comme le commutateur de puissance, par un bouton de commande.In known manner, the various displays, each corresponding to a sequence, are produced by a device with indicator lights aligned along the strip. The lighting of each indicator is obtained using a bulb carried by a chain stretched between two sprockets, one of which, called a drive, is located in the axis of the power switch and operated, like the power switch , by a command button.

Ce dispositif d'affichage mécanique présente des inconvénients car l'emploi de pignons et d'une chaîne provoque un mauvais positionnement de l'ampoule et rend l'affichage peu fiable.This mechanical display device has drawbacks because the use of sprockets and a chain causes the bulb to be positioned incorrectly and makes the display unreliable.

De manière connue, la température fait également l'objet d'un affichage par une aiguille se déplaçant le long d'un cadran linéaire, et d'une sélection par un commutateur thermostatique.In known manner, the temperature is also the subject of a display by a needle moving along a linear dial, and of a selection by a thermostatic switch.

Ce dispositif d'affichage mécanique présente également des inconvénients tels que par exemple, une complexité mécanique et une fiabilité faible.This mechanical display device also has drawbacks such as, for example, mechanical complexity and low reliability.

Le Brevet FR-A-2489485 utilise une pluralité de boutons de sélection interconnectés et une pluralité de diodes d'affichage dont une diode unique est allumée à la fois. Cette diode électroluminescente indique la séquence choisie et non la température atteinte au moment de l'affichage.The patent FR-A-2489485 uses a plurality of interconnected selection buttons and a plurality of display diodes, one single diode of which is lit at the same time. This light-emitting diode indicates the chosen sequence and not the temperature reached at the time of display.

This display ensures, for example, the display of sequences.

L'afficheur 3 est composé de voyants lumineux 3A éclairant des secteurs 3' translucides, munis de raies transparentes, et faisant partie du bandeau. Les raies sont alors éclairées par les voyants. Cet afficheur assure, par exemple, l'affichage de la température.The display 3 is composed of indicator lights 3A illuminating translucent sectors 3 ′, provided with transparent lines, and forming part of the strip. The lines are then lit by the LEDs. This display ensures, for example, the temperature display.

Derrière le bandeau 1, chaque secteur 2' du tube fluorescent 2A comporte des connexions électriques 4 et chaque voyant lumineux 3A comporte des connexions électriques 5.Behind the strip 1, each sector 2 ′ of the fluorescent tube 2A has electrical connections 4 and each indicator light 3A has electrical connections 5.

Il est représenté en traits interrompus un commutateur de sélection 10 situé derrière le bandeau, entre un bouton de commande et un commutateur de puissance par exemple, non représentés. Le commutateur de sélection 10 sera décrit plus en détail dans les figures 2 et 3 et le bouton de commande et le commutateur de puissance y seront représentés.There is shown in broken lines a selection switch 10 located behind the strip, between a control button and a power switch for example, not shown. The selection switch 10 will be described in more detail in FIGS. 2 and 3 and the control button and the power switch will be represented there.

Sur ce bandeau 1 est également représenté un bouton de commande 6B manoeuvrant un commutateur thermostatique par exemple.Also shown on this strip 1 is a control button 6B operating a thermostatic switch, for example.

Dans la figure 2, il est représenté un commutateur 20 qui peut être soit un commutateur de puissance, soit un commutateur thermostatique.In Figure 2, there is shown a switch 20 which can be either a power switch or a thermostatic switch.

Ce commutateur 20 comprend des connexions électriques 21 et un axe 22 comportant un méplat 23, cet axe s'engageant dans un bouton de commande 6A.This switch 20 comprises electrical connections 21 and an axis 22 comprising a flat 23, this axis engaging in a control button 6A.

Le commutateur de sélection 10 comporte une plaque-support 11 de circuit imprimé munie de pistes 12 reliées à des connexions électriques 13. Ces connexions électriques 13 sont bien entendu reliées électriquement aux connexions électriques 4 du tube 2A ou aux connexions électriques 5 des voyants lumineux 3A.The selection switch 10 comprises a support plate 11 of the printed circuit provided with tracks 12 connected to electrical connections 13. These electrical connections 13 are of course electrically connected to the electrical connections 4 of the tube 2A or to the electrical connections 5 of the indicator lights 3A .

Cette plaque-support 11 comporte également des balais 14 qui connectent les pistes 12 entre elles pour allumer les secteurs 2' à raies lumineuses ou les secteurs 3' à raies éclairées de manière appropriée. Ces balais sont enfichés dans une fente 16 d'une pièce porte-balais 15. Cette pièce 15 comporte une partie 17 qui permet de fixer par enclipsage la plaque support de circuit imprimé contre le bandeau 1 comme le montre la figure 3.This support plate 11 also includes brushes 14 which connect the tracks 12 to one another in order to light the sectors 2 ′ with light lines or the sectors 3 ′ with appropriately lit lines.

Un crantage 30 poussé par un ressort 31 s'engage dans des rainures 19 de la pièce porte-balais 15, ceci étant également visible en figure 3.A notch 30 pushed by a spring 31 engages in grooves 19 of the brush-holder part 15, this being also visible in FIG. 3.

Une opération de sélection et d'affichage d'une séquence se passe de la manière suivante :A sequence selection and display operation takes place as follows:

Un opérateur tourne le bouton 6A qui commande dans ce cas le commutateur de puissance 20 assurant la sélection de la séquence. Le commutateur de sélection 10 commande l'affichage de la séquence par l'intermédiaire des balais 14 qui relient les pistes 12 correspondantes à la séquence choisie.An operator turns the button 6A which in this case controls the power switch 20 ensuring the selection of the sequence. The selection switch 10 controls the display of the sequence by means of the brushes 14 which connect the tracks 12 corresponding to the chosen sequence.

Ces pistes alimentent le tube fluorescent 2A et le secteur 2' à raies lumineuses correspondant s'allume, les autres étant éteints.These tracks supply the fluorescent tube 2A and the sector 2 ′ with corresponding light lines comes on, the others being off.

Une opération de sélection et d'affichage d'une température se passe de la manière suivante :A temperature selection and display operation takes place as follows:

Un opérateur tourne le bouton 6B qui commande dans ce cas le commutateur thermostatique réglant la température de l'appareil. Le commutateur de sélection 10 commande l'affichage de la température par l'intermédiaire des balais 14 qui relient les pistes 12 correspondantes à la température choisie. Ces pistes alimentent les voyants lumineux 3A et les secteurs 3' à raies éclairées s'allument graduellement, c'est-à-dire qu'à partir d'une extrémité et à une température basse aucun secteur n'est allumé et au fur et à mesure que la température augmente, le secteur adjacent s'allume puis le secteur adjacent à ce dernier et ainsi de suite pour réaliser une bande lumineuse de longueur variable. Chaque secteur représente, par exemple, une augmentation de température de 25 °C.An operator turns the knob 6B which in this case controls the thermostatic switch regulating the temperature of the appliance. The selection switch 10 controls the display of the temperature by means of the brushes 14 which connect the tracks 12 corresponding to the chosen temperature. These tracks supply the indicator lights 3A and the sectors 3 ′ with illuminated lines light up gradually, that is to say that from one end and at a low temperature no sector is lit and as and as the temperature increases, the adjacent sector lights up, then the sector adjacent to the latter and so on to produce a light strip of variable length. Each sector represents, for example, a temperature increase of 25 ° C.
