Abstract

L’invention concerne un réfrigérateur comprenant un corps avec des compartiments séparés par des cloisons d’isolation thermique, une chambre de stockage agencée dans l’un des compartiments, une source lumineuse disposée dans la chambre de stockage et une unité de régulation permettant de régler la température de la chambre de stockage sur diverses zones de température. La source lumineuse peut émettre des couleurs différentes. L’unité de régulation sélectionne, selon une zone de température donnée de la chambre de stockage, une couleur parmi celles disponibles et fait en sorte que la source lumineuse émette une lumière de cette couleur. Le réfrigérateur facilite la détermination des conditions de température de chaque chambre, et s’avère donc commode.
