Abstract

L'invention concerne une bouilloire électrique dotée d'un corps de bouilloire ayant une ouverture verseuse dans sa partie supérieure avant, un récipient interne logé dans le corps de bouilloire, et dans lequel le liquide est versé, un corps de couvercle ménagé de manière amovible de façon à fermer l'ouverture supérieure du récipient interne, et une section de détection d'ébullition qui est située dans une chambre de détection d'ébullition ménagée dans la partie supérieure arrière du corps de bouilloire et qui détecte l'ébullition du liquide dans le récipient interne. Un passage d'évacuation de vapeur est formé dans la partie supérieure du corps de bouilloire, et le passage d'évacuation de vapeur évacue à la fois la vapeur qui a été fournie dans la chambre de détection d'ébullition et l'eau condensée qui a été condensée à partir de la vapeur, vers l'ouverture verseuse. Du fait de cette configuration, l'eau condensée passant à travers le passage d'évacuation de vapeur ne peut pas s'accumuler sur la surface périphérique de la bouilloire électrique.
