Abstract

La présente invention concerne un réfrigérateur comprenant : un corps principal ; une chambre de congélation, disposée dans une partie inférieure du corps principal ; et une chambre de réfrigération et une chambre de fabrication de glaçons, disposées dans une partie supérieure du corps principal. Un matériau d'isolation thermique est injecté dans le corps et expansé en monobloc à l'intérieur de celui-ci pour former simultanément la chambre de réfrigération et la chambre de fabrication de glaçons en tant qu'espaces indépendants d'isolation thermique. La chambre de fabrication de glaçons est refroidie par une unité indépendante de refroidissement, différente de celles de la chambre de réfrigération et de la chambre de congélation, de façon à réguler indépendamment sa température et peut être ouverte ou fermée par une porte de chambre de fabrication de glaçons, fournie séparément des portes d'ouverture et de fermeture de la chambre de réfrigération et la chambre de congélation. C'est-à-dire que dans un état dans lequel un espace de stockage dans le corps principal se divise dès l'origine en chambre de réfrigération, en chambre de congélation et en chambre de fabrication de glaçons, le matériau d'isolation thermique est injecté et moussé en monobloc pour former simultanément la chambre de réfrigération, la chambre de congélation et la chambre de fabrication de glaçons en tant qu'espaces indépendants d'isolation thermique, tandis que la température de la chambre de fabrication de glaçons peut être régulée indépendamment à l'aide de l'unité de refroidissement, indépendamment de celles de la chambre de réfrigération et de la chambre de congélation. Ainsi, la chambre de fabrication de glaçons ne dépend ni de la chambre de réfrigération ni de la chambre de congélation, mais est formée et activée en tant qu'élément indépendant, complètement différent de la chambre de réfrigération et de la chambre de congélation.
