Description

La présente invention concerne un dispositif de mesure de température dans un four de cuisson.The present invention relates to a device for measuring temperature in a baking oven.

Elle concerne également un four de cuisson équipé d'un tel dispositif de mesure de température conforme à l'invention.It also relates to a cooking oven equipped with such a temperature measuring device according to the invention.

De manière générale, la présente invention concerne les fours de cuisson domestiques dans lesquels un dispositif de mesure de température doit être mis en oeuvre pour assurer la sécurité des organes du four et de l'utilisateur.In general, the present invention relates to domestic cooking ovens in which a temperature measuring device must be implemented to ensure the safety of the oven members and the user.

Ce four de cuisson comprend une enceinte de cuisson et au moins un élément chauffant alimenté en énergie. La température à l'intérieur de l'enceinte de cuisson est régulée par des moyens de commande activant ledit au moins un élément chauffant. Le dispositif de mesure de température permet de surveiller la température à l'intérieur de l'enceinte de cuisson et d'actionner des moyens de sécurité lors d'un dépassement d'un seuil de température.This cooking oven comprises a cooking chamber and at least one heating element supplied with energy. The temperature inside the cooking chamber is regulated by control means activating said at least one heating element. The temperature measuring device makes it possible to monitor the temperature inside the cooking chamber and to actuate safety means when a temperature threshold is exceeded.

On connaît d'une part des fours de cuisson comprenant un thermostat bimétallique assurant la régulation de la température d'un four et monté à l'intérieur d'une ouverture de façon à être en liaison directe, non pas avec les éléments de chauffe, mais avec la chambre de cuisson. Une paroi latérale de la chambre de cuisson présente une ouverture agencée pour permettre le montage d'un thermostat avec interposition d'une plaquette isolante de protection. Le thermostat bimétallique est disposé entre la chambre de cuisson et le boîtier du four.On the one hand, there are known baking ovens comprising a bimetallic thermostat controlling the temperature of an oven and mounted inside an opening so as to be in direct connection, not with the heating elements, but with the cooking chamber. A side wall of the cooking chamber has an opening arranged to allow the mounting of a thermostat with the interposition of an insulating protective pad. The bimetallic thermostat is located between the baking chamber and the oven housing.

Cependant, ces dispositifs de mesure de température ont l'inconvénient de ne pas permettre d'assurer le bon fonctionnement du four en fonction de la température de l'air entre le boîtier et l'enceinte de cuisson et de la température de l'enceinte de cuisson. En outre, la plaquette isolante de protection empêche le mouvement de l'air chaud de l'enceinte de cuisson vers le thermostat bimétallique et de circuler le long de celui-ci. Ces dispositifs de mesure de température permettent d'assurer la régulation de la température à l'intérieur de l'enceinte de cuisson et non la sécurité du four dès le dépassement d'un seuil de température.However, these temperature measuring devices have the disadvantage of not allowing to ensure the proper operation of the oven depending on the air temperature between the housing and the cooking chamber and the temperature of the enclosure Cooking. In addition, the insulating protective pad prevents the movement of hot air from the cooking chamber to the bimetallic thermostat and circulating along it. These temperature measuring devices make it possible to regulate the temperature inside the cooking chamber and not the safety of the oven as soon as a temperature threshold is exceeded.

On connaît d'autre part des fours de cuisson comprenant un thermostat bimétallique assurant la sécurité des composants disposés entre le boîtier et l'enceinte de cuisson sans aucune circulation d'air chaud de l'enceinte de cuisson à proximité du thermostat bimétallique.On the other hand, there are known baking ovens comprising a bimetallic thermostat ensuring the safety of the components arranged between the housing and the cooking chamber without any hot air circulation of the cooking chamber near the bimetallic thermostat.

Cependant, ces dispositifs de mesure de température ont l'inconvénient de détecter un dépassement d'un seuil de température entre le boîtier et l'enceinte de cuisson et en ne tenant pas compte de la température de l'enceinte de cuisson. Le thermostat bimétallique ne permet pas d'avoir un seuil de déclenchement lié à la température interne de l'enceinte de cuisson. Ce qui occasionne un temps de retard lors du déclenchement du thermostat bimétallique puisque la température à l'intérieur de l'enceinte de cuisson a dépassé le seuil maximum toléré et les composants en relation thermique avec l'enceinte de cuisson ont subi ce dépassement de température.However, these temperature measuring devices have the disadvantage of detecting an exceeding of a temperature threshold between the housing and the cooking chamber and not taking into account the temperature of the cooking chamber. The bimetallic thermostat does not allow to have a trigger threshold related to the internal temperature of the cooking chamber. Which causes a delay time when triggering the bimetallic thermostat since the temperature inside the cooking chamber has exceeded the maximum allowed threshold and the components in thermal relation with the cooking chamber have undergone this temperature overrun.

On connaît également un four de cuisson décrit dans le document EP 0 663 568 A1 . Ce document décrit un four de cuisson comprenant un conduit de ventilation du four et un capteur placé en aval d'un ventilateur, ledit ventilateur étant disposé à l'entrée du conduit de ventilation. Ce four de cuisson permet de mesurer la température ou de déterminer la composition des fumées sortant de l'enceinte de cuisson par un capteur disposé dans le conduit de ventilation. Ce capteur permet de déterminer si la cuisson des aliments est atteinte ou si un nettoyage par pyrolyse est atteint suite à un procédé de traitement de l'air par catalyse.Also known is a cooking oven described in the document EP 0 663 568 A1 . This document describes a cooking oven comprising an oven ventilation duct and a sensor placed downstream of a fan, said fan being arranged at the entrance of the ventilation duct. This baking oven makes it possible to measure the temperature or to determine the composition of the fumes leaving the cooking chamber by a sensor disposed in the ventilation duct. This sensor makes it possible to determine whether the cooking of the food is reached or whether a pyrolysis cleaning is achieved following a catalytic air treatment process.

Cependant, le document EP0663568 précise qu'un capteur ne peut pas être positionné à proximité de l'enceinte de cuisson pour réguler la température de l'enceinte de cuisson ou déterminer la composition des fumées, et encore moins de placer un capteur dans un mouvement d'air chaud provenant de l'enceinte de cuisson.However, the document EP0663568 specifies that a sensor can not be positioned near the cooking chamber to regulate the temperature of the cooking chamber or determine the composition of the fumes, let alone to place a sensor in a hot air movement from of the cooking chamber.

Par conséquent d'après le document EP0663568 , ce capteur doit être placé dans un conduit de ventilation dans lequel un flux d'air ambiant balaye ledit capteur afin d'éviter l'arrivée directe des fumées sur celui-ci et ainsi le refroidir.Therefore according to the document EP0663568 , this sensor must be placed in a ventilation duct in which a flow of ambient air scans the said sensor to prevent the direct arrival of smoke on it and thus cool it.

En outre, le capteur est placé dans un mélange de flux d'air dont un flux d'air chaud provenant de l'enceinte de cuisson et d'un flux d'air ambiant. La proportion de la quantité d'air chaud provenant de l'enceinte de cuisson par aspiration est réduite par rapport à la quantité d'air ambiant fournie par le ventilateur dans le conduit de ventilation. La quantité d'air ambiant fournie par le ventilateur dans le conduit de ventilation principal est grandement supérieure à la quantité d'air chaud provenant de l'enceinte de cuisson par aspiration dans un conduit auxiliaire débouchant dans le conduit principal de ventilation.In addition, the sensor is placed in a mixture of air flow including a hot air flow from the cooking chamber and a flow of ambient air. The proportion of the amount of hot air from the suction cooking chamber is reduced compared to the amount of ambient air supplied by the fan in the ventilation duct. The amount of ambient air supplied by the fan in the main ventilation duct is much greater than the amount of hot air from the suction cooking chamber in an auxiliary duct opening into the main ventilation duct.

On connaît également un four de cuisson décrit dans le document GB 1 130 803 A . Ce document décrit un four de cuisson autonettoyant par la chaleur comprenant un premier interrupteur à thermostat de verrouillage. Lorsque la température de l'air dans la cavité dépasse un seuil de température, ledit thermostat de verrouillage se ferme et permet l'allumage d'un voyant, la mise en fonctionnement d'un ventilateur et le verrouillage de la porte. Un second interrupteur thermostatique à haute température est ouvert et fermé pour réguler la température dans la cavité au cours d'une opération de nettoyage de ladite cavité.Also known is a cooking oven described in the document GB 1 130 803 A . This document describes a self-cleaning baking oven by heat comprising a first lock thermostat switch. When the temperature of the air in the cavity exceeds a temperature threshold, said locking thermostat closes and allows the lighting of a light, the starting of a fan and the locking of the door. A second high temperature thermostatic switch is opened and closed to regulate the temperature in the cavity during a cleaning operation of said cavity.

Cependant, ce four de cuisson autonettoyant présente l'inconvénient d'utiliser un ensemble de dispositifs d'interrupteurs pour assurer un mode de nettoyage par la chaleur de la cavité. L'interrupteur thermostatique de ce four de cuisson ne permet pas d'avoir un seuil de déclenchement lié à la température interne de l'enceinte de cuisson. Ce qui occasionne un temps de retard lors du déclenchement de l'interrupteur thermostatique puisque la température à l'intérieur de l'enceinte de cuisson a dépassé le seuil maximum toléré et les composants en relation thermique avec l'enceinte de cuisson ont subi ce dépassement de température.However, this self-cleaning cooking oven has the disadvantage of using a set of switch devices to provide a mode of cleaning by the heat of the cavity. The thermostatic switch of this oven does not allow to have a trip threshold related to the internal temperature of the cooking chamber. This causes a delay time when triggering the thermostatic switch since the temperature inside the cooking chamber has exceeded the maximum allowed threshold and the components in thermal relation with the cooking chamber have undergone this overrun temperature.
