Abstract

L'invention concerne un réfrigérateur comprenant un distributeur disposé dans une partie concave d'une porte et tourné vers la surface avant de la porte. Un réservoir d'eau est installé entre la surface arrière du distributeur et le revêtement de la porte définissant la surface arrière de la porte. Le réservoir d'eau stocke l'eau provenant d'une source extérieure d'alimentation, tandis que l'eau est maintenue à relativement basse température, et évacue l'eau vers l'extérieur à travers le distributeur. De plus, une buse, à travers laquelle l'eau est évacuée à partir du réservoir d'eau, est reliée directement à un tuyau de drainage du distributeur, de sorte que les utilisateurs peuvent toujours prendre l'eau maintenue à une température constante.
