Abstract

L'invention concerne un réfrigérateur (1) qui est équipé : d'une partie corps principal (2) dans laquelle est formée une chambre de stockage (3); d'une porte (4) qui ouvre et ferme la chambre de stockage (3) par pivotement sur la partie corps principal (2); d'un premier élément de blocage (10) agencé sur la partie corps principal (2) ou la porte (4); et d'un second élément de blocage (20) agencé sur la partie corps principal (2) ou la porte (4) sans premier élément de blocage (10), et régulant l'amplitude de rotation de la porte (4) par contact avec le premier élément de blocage (10). Le premier élément de blocage (10) s'écarte dans la direction périphérique avec l'axe de pivotement de la porte (4) pour centre, et possède une première et une seconde partie de contact (11, 12) formant une différence de niveau dans la direction axiale. La porte (4) est bloquée par contact du second élément de blocage (20) et de la première partie de contact (11) lorsque la porte (4) est ouverte. La porte (4) est soulevée par glissement du second élément de blocage (20) et de la première partie de contact (11) dont au moins l'un des deux possède une face inclinée. L'amplitude de rotation de la porte (4) est régulée par contact du second élément de blocage (20) et de la seconde partie de contact (12).
