Abstract
(EN)
A refrigerator of the present invention comprises: storage chambers for storing food; a cooler for supplying cold to the storage chambers; a first tray assembly for forming a portion of an ice-making cell, which is the space in which water phase-changes into ice by the cold; a second tray assembly for forming another portion of the ice-making cell; a heater positioned adjacently to the first tray assembly and/or the second tray assembly; and a control unit for controlling the heater, wherein the control unit turns on the heater in at least a portion of a section while the cooler supplies cold, so that bubbles dissolved in the water inside the ice-making cell move toward liquid water from a portion in which ice is formed, thereby enabling clear ice to be formed, and the control unit increases the heating rate of the heater when the heat transfer rate between the cold inside the storage chambers and the water of the ice-making cell is increased, and reduces the heating rate of the heater when the heat transfer rate between the cold inside the storage chambers and the water of the ice-making cell is reduced, so that the ice-making speed of the water inside the ice-making cell can be maintained within a predetermined range that is lower than the ice-making speed when ice making is performed while the heater is turned off.

La présente invention concerne un réfrigérateur qui comprend : des chambres de stockage destinées à stocker des aliments ; un refroidisseur qui permet de fournir du froid aux chambres de stockage ; un premier ensemble plateau formant une partie d'une cellule de production de glace, ladite partie étant l'espace dans lequel l'eau change de phase pour former de la glace à l'aide du froid ; un second ensemble plateau formant une autre partie de la cellule de production de glace ; un dispositif de chauffage positionné adjacent au premier ensemble plateau et/ou au second ensemble plateau ; une unité de commande qui permet de commander le dispositif de chauffage. L'unité de commande allume le dispositif de chauffage dans au moins une partie d'une section pendant que le refroidisseur fournit du froid, de sorte que les bulles dissoutes dans l'eau à l'intérieur de la cellule de production de glace se déplacent vers l'eau liquide à partir d'une partie de formation de glace, ce qui permet la formation d'une glace transparente, et l'unité de commande augmente le taux de chauffage du dispositif de chauffage lorsque le taux de transfert de chaleur entre le froid à l'intérieur des chambres de stockage et l'eau de la cellule de production de glace est augmenté, et réduit le taux de chauffage du dispositif de chauffage lorsque le taux de transfert de chaleur entre le froid à l'intérieur des chambres de stockage et l'eau de la cellule de production de glace est réduit, de sorte que la vitesse de production de glace à l'intérieur de la cellule de production de glace peut être maintenue dans une plage prédéterminée, inférieure à la vitesse de production de glace lorsque la production de glace est effectuée pendant que le dispositif de chauffage est éteint.
