PURPOSE:To improve feasibility of refrigerator by providing a freezing chamber, refrigerating chamber and freezing-refrigerating chamber to switch the freezing- refrigerating chamber to the freezing or refrigerating chamber if necessary to adjustably increase or decrease the volume of refrigerating and freezing chambers. CONSTITUTION:A freezing-refrigerator has freezing chamber 5 on the upper portion, a switching chamber (freezing-refigerating chamber) 6 on the lower portion and a partition wall 10 dividing the refrigerator into said both chambers. After cool air cooled by a cooler 11 is jetted into the freezing chamber 5 by a blower 15, a portion of the cool air is jetted into the switching chamber 6 through a cool air path 21 having a damper thermo 23 and the remaining cool air is returned to the cooler 11 through a pressure chamber 25 controllably opened and closed by a switching damper 30. A refrigerating chamber 38 is provided at the side of said freezing chamber 5 and switching chamber 6 to bestride both chambers. An inner box 6a integrates these three chambers into one body. A piping 37 through which high temperature refrigerant passes is provided at the adiabatic material side of the partition wall 39 formed between the chambers 5,6 and the chamber 38. |
