Abstract

L'invention concerne un réfrigérateur dans lequel il est possible d'empêcher la congélation dans un tuyau de dégivrage sans diminuer les propriétés d'isolation thermique globales et la facilité d'assemblage du réfrigérateur. Le réfrigérateur est équipé : d'un corps de boîte qui a une boîte interne formant une chambre de stockage et une boîte externe formant un cadre externe sur le côté externe de la boîte interne; d'un dispositif de refroidissement qui génère de l'air froid; d'un compresseur qui actionne le dispositif de refroidissement; un bac de récupération qui collecte l'eau de dégivrage générée par le dispositif de refroidissement; un tuyau de dégivrage qui permet à l'eau de dégivrage de s'écouler vers le bac de récupération; un premier panneau d'isolation sous vide qui est fixé à la boîte externe; et un second panneau d'isolation sous vide qui est fixé à la boîte interne. Le dispositif de refroidissement, le compresseur et le tuyau de dégivrage sont disposés entre la boîte interne et la boîte externe, et le second panneau d'isolation sous vide est disposé entre la boîte interne et le tuyau de dégivrage et a des dimensions plus petites que le premier panneau d'isolation sous vide.
