Abstract

PURPOSE:To devise to change the rate of capacities between a refrigerating and a freezing chamber according to the necessity by using a cooler, a fan, switching damper, a temperature regulator for each, and two damper thermostats. CONSTITUTION:When a switching damper 30 is operated to open a cold air passage 28, the cold air is partly conducted through a duct plate 13 to be blown off into a freezing chamber from a cold-air blowing off exit 17, and the remainder is conducted through a passage 26, a compressing chamber 25, and the passage 28 tube returned to a cooler 11. The cold air in the freezing chamber 5 is sucked into a cold air passage 21 through a cold air suction port 20. The cold air is checked to be blown into a switching chamber 6 by a damper thermostat 23 provided in a passage 22 to regulate the cold air automatically, and returned to the cooler 11 through the passage 28, while the cold air in the switching chamber 6 is also returned to the cooler 11 through a passage 29. In this circulation, the switching chamber 6 can be used as a refrigerating chamber. Similarly, when the switching damper 30 is operated to close the cold air passage 28, the freezing-refrigerating chamber can be used as a freezing chamber.
