  • the dispenser 5 of the refrigerator 100 can provide both first ice and crushed ice. That is, when providing the first ice, the ice breaking device 54 is not operated, and the first ice in the ice bank 19 is directly discharged from the discharge port 13 through the ice passage 53. When providing the crushed ice, the ice crusher 54 is operated to crush the first ice, and the obtained crushed ice is discharged from the discharge port 13 through the ice passage 53.
  • the comparative refrigerator 100 has the following disadvantages. Since the blade of the ice breaking device 54 is sharp, there is a possibility that the user touches the blade and gets damaged, and safety is low. When rotating the blade during ice breaking, a strong force is applied to the ice, so the output of the motor used to rotate the blade is high and noise may be generated. Since the ice passage 53 has a cross-sectional area that matches the size of the first ice, when providing the crushed ice, the crushed ice is likely to scatter from the discharge port 13 and spill out of the container. Since the ice making chamber 51 is formed inside the refrigerator compartment 20, it is difficult to cool it to a low temperature like the freezer compartment 21.
  • the first ice having a relatively large size is made in such an ice making chamber 51, efficient ice making is difficult, ice making time becomes long, and convenience is lowered. Moreover, the transparency of the manufactured ice tends to be low, and the quality of the ice is low. Since both the first ice and the crushed ice are covered by the ice making device 50, it is necessary to make the ice making device 50 large. For this reason, the space which the ice making room 51 occupies in the inside of the refrigerator compartment 20 becomes large, and the space which can accommodate a foodstuff in the refrigerator compartment 20 will reduce significantly.
  • the present invention is not limited to the embodiment described above.
  • the first chamber 14 may be formed as a separate chamber independent of the freezing chamber 21.
  • the second chamber 15 may be formed as a separate chamber independent of the refrigerator compartment 20.
  • the first ice making device 3 may not be configured to automatically make the first ice.
  • a configuration in which the user manually performs the water supply operation to the first ice tray 16 and the operation of separating the first ice from the first ice tray 16 may be employed.
  • an ice removing means of the ice making device an ejector that scrapes out ice from the ice making tray may be provided.
  • An ice removing means capable of flowing hot gas through the refrigerant pipe in contact with the ice tray may be used.
  • the ice making device arranges a metal ice tray cooled by a refrigerant pipe so that its opening is horizontal, and circulates water from the top to make ice. Also good.

Abstract

Réfrigérateur comprenant : un corps ayant une première chambre et une seconde chambre; un premier moyen de fabrication de glace ayant un premier plateau de fabrication de glace disposé à l'intérieur de la première chambre; un second moyen de fabrication de glace ayant un second plateau de fabrication de glace disposé à l'intérieur de la seconde chambre; et un distributeur ayant un orifice de décharge qui est apte à décharger de la glace. La température à l'intérieur de la première chambre est maintenue à une température inférieure à la température à l'intérieur de la seconde chambre. Le premier plateau de fabrication de glace est configuré pour fabriquer une première glace ayant une première taille. Le second plateau de fabrication de glace est configuré pour fabriquer une seconde glace ayant une seconde taille plus petite. Le second plateau de fabrication de glace est positionné au-dessus de l'orifice de décharge. Le distributeur est apte à décharger la seconde glace à partir de l'orifice de décharge.
