Abstract

Le but de la présente invention est de fournir un réfrigérateur capable d'informer un utilisateur lorsqu'une porte est dans un état non fermé tout en empêchant un son d'alarme inutile. Lorsqu'au moins une durée prédéfinie qui s'est écoulée depuis l'état ouvert d'une porte (5), qui ouvre et ferme une section d'ouverture d'un compartiment, a été détectée tel que la température à l'intérieur du compartiment soit égale ou supérieure à une température définie et qu'il n'y a pas de changement du poids à l'intérieur du compartiment, le réfrigérateur détermine que la porte (5) est dans un état non fermé, et informe l'utilisateur de l'état non fermé de la porte (5). En outre, lorsqu'une pluralité de compartiments sont prévus, il est souhaitable que les températures définies des compartiments respectifs soient réglées à différentes températures.
