Abstract
(EN) A refrigerator (1), comprising a box body (2), a box door (13) having a top portion provided with an accommodating portion (18) for installing a vacuum pump (3), a low-pressure storage unit and an air leakage prevention unit (40); the air leakage prevention unit (40) comprises a vertical column (61) formed on the accommodating portion (18), a first through-hole (62) penetrating the vertical column (61), and a floating column (57) installed in the first through-hole (62); the vertical column (61) is provided with a first end portion (61a) located in the accommodating portion (18) and an air outlet (62a) located at the first end portion (61a); the floating column (57) is provided with a second baffle (59) cooperating with the first end portion (61a) to open or close the air outlet (62a); the floating column (57) and the vertical column (61) together define an air extraction channel (70); a first shield cover (52) communicating the air extraction channel (70) with the vacuum pump (3) is sleeved outside the first end portion (61a); and the floating column (57) is able to reciprocate along the first through-hole (62) under the action of air pressure, so as to open or close the air outlet (62a).
(FR) La présente invention concerne un réfrigérateur (1), comprenant un corps de boîte (2), une porte de boîte (13) ayant une partie supérieure pourvue d'une partie de réception (18) pour installer une pompe à vide (3), une unité de stockage basse pression et une unité de prévention de fuite d'air (40) ; l'unité de prévention de fuite d'air (40) comprend une colonne verticale (61) formée sur la partie de réception (18), un premier trou traversant (62) pénétrant dans la colonne verticale (61), et une colonne flottante (57) installée dans le premier trou traversant (62) ; la colonne verticale (61) est pourvue d'une première partie extrémité (61a) située dans la partie de réception (18) et d'une sortie d'air (62a) située au niveau de la première partie extrémité (61a) ; la colonne flottante (57) est pourvue d'un second déflecteur (59) coopérant avec la première partie extrémité (61a) pour ouvrir ou fermer la sortie d'air (62a) ; la colonne flottante (57) et la colonne verticale (61) délimitent ensemble un canal d'extraction d'air (70) ; un premier couvercle de protection (52) faisant communiquer le canal d'extraction d'air (70) avec la pompe à vide (3) est emmanché à l'extérieur de la première partie extrémité (61a) ; et la colonne flottante (57) peut effectuer un mouvement de va-et-vient le long du premier trou traversant (62) sous l'action de la pression d'air, de façon à ouvrir ou fermer la sortie d'air (62a).
(ZH) 一种冰箱(1),其具有箱体(2)、顶部设有安装真空泵(3)的容纳部(18)的箱门(13)、低压储藏单元及防漏气单元(40);防漏气单元(40)包括形成于容纳部(18)上的立柱(61)、贯穿立柱(61)的第一通孔(62)、安装于第一通孔(62)内的浮动柱(57);立柱(61)具有位于容纳部(18)内的第一端部(61a)及位于第一端部(61a)的出气口(62a);浮动柱(57)上设有与第一端部(61a)配合以打开或关闭出气口(62a)的第二挡板(59);浮动柱(57)与立柱(61)共同限定出抽气通道(70);第一端部(61a)外套设有连通抽气通道(70)和真空泵(3)的第一挡罩(52);浮动柱(57)受到气压作用能够沿第一通孔(62)作往复运动,以打开或关闭出气口(62a)。
