Abstract
(EN)
A refrigerator of the present invention comprises: a storage chamber for storing food; a cool air supplying means for supplying cool air to the storage chamber; a first tray which forms a part of an ice-making cell in which water is phase-changed to ice by the cool air; a second tray which forms another part of the ice-making cell and can be in contact with the first tray during an ice-making process; a water supply valve for adjusting a flow of the water supplied to the ice-making cell; a water supply amount detector for detecting the amount of water supplied to the ice-making cell; and a controller for controlling the water supply valve. The controller controls the water supply valve to supply water to the ice-making cell as much as a first reference water supply amount, for supplying water to the ice-making cell at a water supply position of the second tray. After finishing the water supply as much as the first reference water supply amount, the controller moves the second tray to an ice-making position and determines whether the water supply amount of the ice-making cell has reached a target water supply amount by using the water supply amount detector. When the water supply amount of the ice making cell has reached the target water supply amount, the controller starts ice-making, and when the water supply amount of the ice making cell has not reached the target water supply amount, the controller moves the second tray back to the water supply position and controls the water supply valve to supply water as much as a second reference water supply amount which is less than the first reference water supply amount.

La présente invention concerne un réfrigérateur comprenant : une chambre de stockage pour stocker des aliments ; un moyen d'alimentation en air froid pour fournir de l'air froid à la chambre de stockage ; un premier plateau qui forme une partie d'une cellule de fabrication de glace dans laquelle de l'eau est changée en glace par l'air froid ; un second plateau qui forme une autre partie de la cellule de fabrication de glace et qui peut être en contact avec le premier plateau pendant un processus de fabrication de glace ; une vanne d'alimentation en eau pour ajuster un écoulement de l'eau fournie à la cellule de fabrication de glace ; un détecteur de quantité d'alimentation en eau pour détecter la quantité d'eau fournie à la cellule de fabrication de glace ; et un dispositif de commande pour commander la soupape d'alimentation en eau. Le dispositif de commande commande la vanne d'alimentation en eau pour fournir de l'eau à la cellule de fabrication de glace ainsi qu'une première quantité d'alimentation en eau de référence, pour fournir de l'eau à la cellule de fabrication de glace à une position d'alimentation en eau du second plateau. Après la fin de l'alimentation en eau dans une quantité égale à la première quantité d'alimentation en eau de référence, le dispositif de commande déplace le second plateau vers une position de fabrication de glace et détermine si la quantité d'alimentation en eau de la cellule de production de glace a atteint une quantité d'alimentation en eau cible à l'aide du détecteur de quantité d'alimentation en eau. Lorsque la quantité d'alimentation en eau de la cellule de fabrication de glace a atteint la quantité d'alimentation en eau cible, le dispositif de commande démarre la fabrication de glace, et lorsque la quantité d'alimentation en eau de la cellule de fabrication de glace n'a pas atteint la quantité d'alimentation en eau cible, le dispositif de commande déplace le second plateau vers la position d'alimentation en eau et commande la vanne d'alimentation en eau pour fournir de l'eau dans une quantité égale à une seconde quantité d'alimentation en eau de référence qui est inférieure à la première quantité d'alimentation en eau de référence.

본 발명의 냉장고는, 음식물이 보관되는 저장실; 상기 저장실로 냉기를 공급하기 위한 냉기공급수단; 물이 상기 냉기에 의해서 얼음으로 상변화되는 공간인 제빙셀의 일부를 형성하는 제 1 트레이; 상기 제빙셀의 다른 일부를 형성하며, 제빙 과정에서는 상기 제 1 트레이와 접촉될 수 있는 제 2 트레이; 상기 제빙셀로 공급되는 물의 유동을 조절하는 급수 밸브; 상기 제빙셀의 급수량을 감지하기 위한 급수량 감지부; 상기 급수 밸브를 제어하는 제어부를 포함한다. 상기 제어부는, 상기 제 2 트레이의 급수 위치에서 상기 제빙셀의 급수를 위하여, 상기 제빙셀로 제 1 기준 급수량만큼 급수되도록 상기 급수 밸브를 제어하고, 상기 제 1 기준 급수량 만큼 급수 완료 후, 상기 제 2 트레이를 제빙 위치로 이동시키고, 상기 급수량 감지부에 의해서 상기 제빙셀의 급수량이 목표 급수량이 도달하였는지 판단한다. 상기 제빙셀의 급수량이 목표 급수량에 도달하였으면, 상기 제어부는 제빙을 시작하고, 상기 제빙셀의 급수량이 목표 급수량에 도달하지 못하였으면 상기 제 2 트레이를 급수 위치로 다시 이동시킨 후 상기 제 1 기준 급수량 보다 작은 제 2 기준 급수량 만큼 급수되도록 상기 급수 밸브를 제어한다.
