  • the water supply tank 602 and the water inside the water supply tank 602 are less likely to freeze, there is no need to provide means for preventing the water supply tank 602 and the water inside the water supply tank 602 from freezing.
  • the means for preventing the water tank 602 and the water inside the water tank 602 from freezing is, for example, the installation of a heater for the water tank 602 .
  • Refrigerator 100 includes refrigerating chamber 31 provided above chilling chamber 32 , refrigerating chamber partition wall 7 provided between refrigerating chamber 31 and chilling chamber 32 , and automatic ice maker 601 . , and a water supply tank 602 for storing water used in the automatic ice maker 601 .
  • the refrigerating compartment partition wall 7 has a concave recess 602a extending from the chilled compartment 32 toward the refrigerating compartment 31, and the water supply tank 602 is accommodated in the recess 602a.
  • the water supply tank 602 is provided inside the refrigerating compartment partition wall 7 positioned between the refrigerating compartment 31 and the chilled compartment 32 .
  • the refrigerator compartment 31 and the chilled compartment 32 are storage compartments with relatively high set temperatures. Therefore, it is possible to suppress the possibility that the water tank 602 and the water inside the water tank 602 freeze.
  • refrigerator 100 is not limited to Embodiments 1 to 5 described above, and various modifications and applications are possible without departing from the scope of the invention.
  • the refrigerator 100 may be configured such that the chilled compartment 32 is provided on the right side and the switching compartment 33 is provided on the left side.
  • Embodiments 1 to 5 can be combined with each other as long as the functions or structures of the respective embodiments are not impaired.
