Abstract

Le problème décrit par la présente invention concerne des appareils électroménagers auxquels des batteries au lithium d'outil électrique peuvent être fixées en tant que source d'alimentation, et qui ont été traditionnellement limités aux cadres photo et aux dispositifs audio, ainsi qu'aux appareils électroménagers à utilisation de chaleur tels que des cafetières, des bouilloires électriques et des poêles électriques. La solution selon l'invention a pour but de permettre la fixation d'un bloc-batterie d'outil électrique, en tant que source d'alimentation, à une gamme plus étendue d'appareils électroménagers afin de pouvoir les utiliser sans cordon et d'améliorer le confort. Une unité d'entreposage à chaud/froid (10) est conçue pour qu'une partie de rétention calorifique (11) destinée à recevoir un objet à rétention calorifique (15) puisse conserver la chaleur au moyen de la fonction de chauffage d'un élément Peltier servant de source de chaleur (12). Un bloc-batterie coulissant (1) est utilisé en tant que source d'alimentation de l'élément Peltier. Le bloc-batterie (1) peut être désaccouplé et chargé et utilisé comme source d'alimentation d'un outil électrique tel qu'un tournevis. En plus de l'entreposage à chaud/froid (10), l'invention peut être appliquée à un fer à repasser ou à un cuiseur à riz.
