Description
La présente invention a pour objet un corps de chauffe pour la génération de vapeur, notamment pour un appareil électroménager. Les corps de chauffe habituellement utilisés sont 5 composés d'un corps aluminium présentant des intersites pour la fabrication de la vapeur et une résistance classique filamentaires composée d'un filament et de poudre de magnésie pour son isolation à l'intérieur d'un tube métallique. La température peut toutefois atteindre très vite 1600 °C, ce qui 10 est préjudiciable à l'aluminium, qui à cette température fond pratiquement instantanément. C'est pourquoi on utilise un premier thermostat mécanique, doublé d'un second, fusible, pour couper l'alimentation électrique en cas de surchauffe. Ce système est coûteux et surtout peu fiable, système couteux dans 15 son ensemble et peu fiable. La présente invention a pour but de proposer un corps de chauffe permettant de remédier aux inconvénients précités, notamment en s'affranchissant de la nécessité d'utiliser un thermostat. 20 Le corps de chauffe selon l'invention comporte une enceinte comprenant : - au moins une ouverture permettant une alimentation en eau, - au moins une autre ouverture permettant l'extraction de 25 la vapeur, ainsi que des moyens de chauffage, et il se caractérise essentiellement en ce que lesdits moyens de chauffage consistent en une multiplicité de résistances céramiques préprogrammées pour fonctionnées à une 30 température précise. Les résistances peuvent prendre différentes formes, rondes plates, tubulaires ... et c'est la masse des composants de la résistance qui détermine sa température nominale. De manière préférentielle, il est prévu de créer un 35 espace entre l'ouverture d'arrivée du liquide à chauffer et la résistance la plus proche, afin d'éviter les chocs thermiques trop importants. Les résistances sont disposées dans l'enceinte, ou bien au contact d'une paroi de l'enceinte.The present invention relates to a heating body for steam generation, in particular for a household appliance. The commonly used heating bodies are composed of an aluminum body having intersites for the manufacture of steam and a conventional filamentary resistance consisting of a filament and magnesia powder for its insulation inside a metal tube. . The temperature can however reach very quickly 1600 ° C., which is detrimental to aluminum, which at this temperature melts practically instantaneously. This is why we use a first mechanical thermostat, coupled with a second, fuse, to cut the power supply in case of overheating. This system is expensive and above all unreliable, costly as a whole and unreliable. The present invention aims to provide a heating body to overcome the aforementioned drawbacks, in particular by avoiding the need to use a thermostat. The heating body according to the invention comprises an enclosure comprising: at least one opening allowing a supply of water, at least one other opening allowing the extraction of steam, as well as heating means, and characterized in that said heating means consist of a plurality of pre-programmed ceramic resistors for operating at a precise temperature. Resistors can take different forms, round flat, tubular ... and it is the mass of components of the resistor that determines its nominal temperature. Preferably, it is intended to create a gap between the inlet opening of the liquid to be heated and the nearest resistor, in order to avoid excessive thermal shocks. The resistors are arranged in the enclosure, or in contact with a wall of the enclosure.
