Abstract

L'invention concerne un appareil de chauffage (100) destiné à chauffer un liquide et comprenant un cadre étanche (1), un corps chauffant (10), une entrée d'eau (14) et une sortie d'eau (11). Le cadre étanche (1) et le corps chauffant (10) sont reliés de manière étanche, et tous les deux entourent et forment une cavité à l'intérieur. La cavité est munie d'un corps étanche (2), et le corps étanche (2) et le corps chauffant (10) entourent et forment un passage d'eau étanche (8) présentant un certain degré de capacité. Le passage d'eau étanche (8) est relié séparément à l'extérieur au moyen de l'entrée d'eau (14) et de la sortie d'eau (11). Le liquide entrant à partir de l'entrée d'eau (14) est restreint et isolé à l'intérieur du passage d'eau étanche (8), coule le long du passage d'eau étanche (8) et sort, à la fin, de la sortie d'eau (11). L'appareil de chauffage (100) réduit le temps d'attente pour le préchauffage de démarrage et fait sortir de l'eau d'une manière continue à une température stable. En outre, la présente invention évite le problème de gazéification et de sortie non continue de l'eau à cause des fuites d'eau provoquées par le fait que l'espace entre un passage de liquide et un élément chauffant comporte une épaisse pellicule d'acier inoxydable.
