Abstract

La présente invention concerne un dispositif (11) spécialement conçu pour isoler thermiquement un espace prédéterminé du compartiment réfrigéré d'un réfrigérateur ou d'un congélateur. Ce dispositif (11) comprend au moins une plaque isolante (12) s'étendant sur une étendue transversale du compartiment réfrigéré (2), qui correspond à l'étendue transversale d'une étagère (10) du réfrigérateur. Dans un mode de réalisation préféré de la présente invention, une plaque de matériau isolant (12) coopère avec l'étagère (10) du réfrigérateur entre une position inactive, dans laquelle aucun volume du compartiment réfrigéré n'est isolé, et une position active, dans laquelle un volume inoccupé est isolé.
