Description

La présente invention concerne un dispositif de commande d'un appareil électroménager.The present invention relates to a control device of an appliance.

De manière générale, elle concerne un appareil électroménager ayant un bandeau de commande.In general, it relates to a household appliance having a control panel.

On connaît déjà des dispositifs de commande d'un appareil électroménager comprenant un ou plusieurs sélecteurs de commande. Le sélecteur de commande comprend un support, une carte électronique montée sur le support, un anneau rotatif et un bouton poussoir. Le bouton poussoir est disposé à l'intérieur de l'anneau rotatif.Already known control devices of a household appliance comprising one or more control selectors. The control selector comprises a support, an electronic board mounted on the support, a rotating ring and a push button. The push button is disposed inside the rotating ring.

Ces dispositifs de commande sont généralement associés à un témoin lumineux pouvant être disposés autour du sélecteur de commande ou intégrés à celui-ci.These control devices are generally associated with a light indicator which can be arranged around the control selector or integrated therewith.

Cependant, ces dispositifs de commande présentent l'inconvénient de disposer le témoin lumineux sur le panneau de commande de l'appareil électroménager indépendamment du sélecteur de commande ou derrière le sélecteur de commande de sorte à illuminer au moins une partie de l'anneau rotatif.However, these control devices have the disadvantage of having the indicator light on the control panel of the appliance independently of the control selector or behind the control switch so as to illuminate at least a portion of the rotary ring.

Par conséquent, la disposition du témoin lumineux par rapport au sélecteur de commande nécessite l'emploi d'éléments supplémentaires et un assemblage précis de sorte à garantir le positionnement entre eux.Therefore, the arrangement of the indicator light with respect to the control selector requires the use of additional elements and a precise assembly so as to guarantee the positioning between them.

Un tel assemblage du panneau de commande d'un appareil électroménager est donc onéreux.Such assembly of the control panel of a household appliance is expensive.

On connaît également le document FR 2 556 857 A1 qui décrit un commutateur rotatif pour appareils ménagers, comprenant un bouton tournant pouvant être escamoté dans la façade de l'appareil par déplacement axial et un anneau gradué décalé axialement dans le sens de l'appareil par rapport audit bouton, solidaire de ce dernier et muni de marques de repères. Le commutateur rotatif comporte un dispositif d'éclairage installé derrière la façade de l'appareil au-dessus de la surface latérale cylindrique déterminée par le diamètre du bouton tournant et éclairant l'anneau gradué en dehors de la surface visible, un anneau gradué au moins transparent, un bouton tournant opaque pour la manoeuvre et un bandeau de parement frontal également opaque.The document is also known FR 2 556 857 A1 which describes a rotating switch for household appliances, comprising a rotary knob which can be retracted into the front of the appliance by axial displacement and a graduated ring axially offset in the direction of the appliance with respect to said knob, integral with the latter and provided with markers. The rotary switch has a lighting device installed behind the facade of the apparatus above the cylindrical lateral surface determined by the diameter of the rotary knob and illuminating the graduated ring out of the visible surface, a graduated ring at least transparent, an opaque turning knob for maneuvering and an opaque front facing strip.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un dispositif de commande d'un appareil électroménager permettant de simplifier la structure d'au moins un sélecteur de commande au moindre coût tout en formant un indicateur lumineux.The present invention aims to solve the aforementioned drawbacks and to provide a control device of a household appliance for simplifying the structure of at least one control selector at the least cost while forming a light indicator.

A cet effet, la présente invention vise, selon un premier aspect, un dispositif de commande d'un appareil électroménager comprenant au moins un sélecteur de commande, ledit au moins un sélecteur de commande comprenant un support, une carte électronique montée sur ledit support, un anneau rotatif et un bouton poussoir, ledit bouton poussoir étant disposé à l'intérieur dudit anneau rotatif.For this purpose, the present invention aims, in a first aspect, a control device of a household appliance comprising at least one control selector, said at least one control selector comprising a support, an electronic card mounted on said support, a rotary ring and a push button, said push button being disposed inside said rotary ring.

Selon l'invention, ledit au moins un sélecteur de commande comprend au moins une première source de lumière ménagée sur ladite carte électronique et disposée en dessous dudit bouton poussoir, et ledit bouton poussoir est un corps transparent ou translucide formant un guide de lumière diffusant la lumière émise par ladite au moins une première source de lumière de sorte à former un premier indicateur lumineux.According to the invention, said at least one control selector comprises at least a first light source provided on said electronic card and disposed below said push button, and said push button is a transparent or translucent body forming a light guide diffusing the light. light emitted by said at least one first light source so as to form a first light indicator.

Ainsi, ledit au moins un sélecteur de commande du dispositif de commande d'un appareil électroménager permet de sélectionner des paramètres de fonctionnement au moyen de l'anneau rotatif et de valider ceux-ci par le bouton poussoir tout en indiquant visuellement au moyen d'un premier indicateur lumineux, formé par au moins une première source de lumière et le bouton poussoir formant un guide de lumière, un état de fonctionnement de l'appareil électroménager.Thus, said at least one control switch of the control device of a household appliance makes it possible to select operating parameters by means of the rotary ring and to validate these by the push button while indicating visually by means of a first indicator light, formed by at least one first light source and the push button forming a light guide, an operating state of the appliance.

L'utilisation du bouton poussoir en tant que guide de lumière permet de s'affranchir de tout élément supplémentaire pour illuminer une zone du sélecteur de commande puisque le bouton poussoir permet de guider la lumière depuis au moins une première source de lumière disposée sur une carte électronique jusqu'à l'extérieur du dispositif de commande de sorte à être visible par l'utilisateur.The use of the push button as a light guide makes it possible to dispense with any additional element for illuminating an area of the control selector since the push button makes it possible to guide the light from at least one first light source arranged on a card electronics to the outside of the controller so as to be visible to the user.

Un tel dispositif de commande permet de minimiser les coûts d'obtention de celui-ci en évitant un assemblage précis dudit au moins un sélecteur de commande pour former un premier indicateur lumineux.Such a control device makes it possible to minimize the costs of obtaining it by avoiding precise assembly of the at least one control selector to form a first light indicator.

Le bouton poussoir est un corps plein permettant de diffuser la lumière au travers de la matière transparente ou translucide constituant celui-ci de sorte à guider la lumière dans une direction prédéterminée.The push button is a solid body for diffusing the light through the transparent or translucent material constituting it so as to guide the light in a predetermined direction.

De cette manière, la lumière émise par ladite au moins une première source de lumière est dirigée au travers du bouton poussoir formant un premier indicateur lumineux de sorte à éviter une diffusion de lumière dans d'autres directions nuisant à la netteté de ce premier indicateur lumineux.In this way, the light emitted by said at least one first light source is directed through the push button forming a first light indicator so as to avoid light scattering in other directions affecting the sharpness of this first light indicator. .

Selon une caractéristique préférée de l'invention, ledit au moins un sélecteur de commande comprend au moins une deuxième source de lumière ménagée sur ladite carte électronique et disposée en périphérie dudit anneau rotatif.According to a preferred feature of the invention, said at least one control selector comprises at least one second light source provided on said electronic card and disposed at the periphery of said rotary ring.

Ainsi, le dispositif de commande d'un appareil électroménager permet d'indiquer visuellement au moyen d'un deuxième indicateur lumineux formé par au moins une deuxième source de lumière disposée en périphérie de l'anneau rotatif un état de fonctionnement de l'appareil électroménager.Thus, the control device of a household appliance makes it possible to indicate visually by means of a second light indicator formed by at least a second light source disposed at the periphery of the rotary ring a state of operation of the appliance. .

La disposition d'au moins une deuxième source de lumière sur la carte électronique dudit au moins un sélecteur de commande et en périphérie de l'anneau rotatif permet de s'affranchir d'un positionnement précis de ladite au moins une deuxième source de lumière et simplifier la structure du sélecteur de commande par une diffusion de lumière en dehors de l'anneau rotatif.The arrangement of at least one second light source on the electronic board of said at least one control selector and at the periphery of the rotary ring makes it possible to dispense with precise positioning of said at least one second source of light and to simplify the structure of the control selector by light scattering outside the rotary ring.
