Definitions

  • the control portion judges that the water supply tank is in the empty state twice in succession, and further stops the power supply to the heating portion after judging that a heat insulating door that blocks a chamber in which the water supply tank is disposed in a freely openable and closeable manner does not perform an opening action.
  • the quick ice making mode is a mode in which ice making is performed in one cycle shorter than a normal ice making operation time
  • the quick freezing mode is a mode in which the freezing chamber 13 is cooled abruptly in preference to the refrigerating chamber 12.
  • step S14 the control portion 40 decreases the energization rate of the heating portion 36 to 30% to continue energization, and the process returns to step S11.
  • FIG 5 a control method of the energization rate C of the refrigerator 10 will be described using FIG 5 .
  • the energization rate C is controlled in such a manner that the water supply tank 31 is the empty state and the operating condition of the refrigerator 10 belongs to the above-mentioned Condition 2.
  • steps S50 to S62 of FIG 5 belong to the control method at the energization rate C.
  • the energization rate to the heating portion 36 is lowered to such an extent that the water in the water supply pipe 35 does not freeze until 70 minutes have passed after the water supply operation to the ice making tray 32, and the energization rate to the heating portion 36 is increased again after 70 minutes have passed from the water supply operation to the ice making tray 32.
  • the heating portion 36 is continuously energized, thereby preventing clogging due to freezing of water remaining in the water supply pipe 35.
  • the energization rate of the heating portion 36 is temporarily low, the water supply pipe 35 does not maintain a high temperature state, bacterial growth in the water remaining in the water supply pipe 35 is prevented, and power consumption of the refrigerator 10 is suppressed.
