Abstract

La présente invention concerne un réfrigérateur qui comprend une boîte ayant une chambre de stockage à l'intérieur de celle-ci, une porte pour ouvrir et fermer la chambre de stockage sur le côté avant de la boîte et un dispositif d'alimentation en eau disposé dans la porte pour fournir de l'eau à l'espace extérieur. Le dispositif d'alimentation en eau comprend une unité de stockage d'eau qui est fixée de manière amovible à la porte, une partie tuyau qui est disposée dans la porte et a des ouvertures aux deux extrémités pour permettre une communication entre la chambre de stockage et l'espace extérieur, ainsi qu'un premier corps de couvercle qui est formé d'une résine et a une partie d'ouverture/fermeture qui ferme l'ouverture de la partie tuyau sur le côté espace extérieur. L'unité de stockage d'eau comprend : un récipient de stockage d'eau stocké dans la chambre de stockage dans un état dans lequel la porte est fermée; et un tuyau d'alimentation relié au récipient de stockage d'eau et inséré dans la partie tuyau à partir du côté chambre de stockage et agencé dans la partie tuyau, le tuyau d'alimentation ayant une partie en saillie faisant saillie vers le côté espace extérieur dans un état dans lequel le tuyau d'alimentation est fixé à la porte et ayant un orifice d'alimentation en eau formé dans la partie en saillie. Dans un état dans lequel l'unité de stockage d'eau n'est pas fixée à la porte, la partie d'ouverture/fermeture du premier couvercle est fermée et ferme ainsi l'ouverture de la partie tuyau sur le côté espace extérieur, ce qui permet de séparer la chambre de stockage et l'espace extérieur. Dans un état dans lequel l'unité de stockage d'eau est fixée à la porte, le premier couvercle est ouvert par la partie d'ouverture/fermeture poussée par la partie en saillie de telle sorte que l'orifice d'alimentation en eau de la partie en saillie est exposé au côté espace extérieur, la partie d'ouverture/fermeture vient en contact avec le tuyau d'alimentation et la chambre de stockage et l'espace extérieur sont séparés par la partie de contact.
