Abstract

L'invention concerne un appareil de froid comprenant une carcasse ainsi qu'une paire de portes placées sur des faces opposées de la carcasse et délimitant ensemble un compartiment intérieur. Une première des deux portes comporte un longeron qui vient s'engager dans le compartiment intérieur lorsque la première porte est fermée, qui présente une surface d'appui sur laquelle une face arrière de la seconde porte vient s'appuyer lorsque les deux portes sont fermées, et qui contient un dispositif chauffant électrique alimenté en énergie électrique par un système d'alimentation électrique placé en partie dans et/ou sur la carcasse et en partie dans et/ou sur la première porte et/ou dans et/ou sur le longeron. Le système d'alimentation électrique comporte une interface fondée sur le principe de la transmission de puissance par induction, laquelle interface établit une connexion électrique entre la partie du système d'alimentation électrique placée dans et/ou sur la première porte et/ou dans et/ou sur le longeron et celle placée dans et/ou sur la carcasse.
