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 increase or decrease the volume of refrigerating and freezing chambers. CONSTITUTION:A freezing refrigerator has a freezing chamber 5 on the upper portion, a swtiching chamber (freezing-refrigerating 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 discharged into the switching chamber 6 through a cool air path 21 having a damper thermo 23 and the remaining cool is returned to the cooler 11 through a pressure chamber 25 controllably opened and closed by a switching damper 30. A partition duct plate 19 introducing a portion of cool air discharged from an outlet 14 by the blower 15 into the switching chamber 6 is divided into a main body 19a and an auxiliary duct plate 19b having a suction port 20. In the frosting of the cooling 11, frost can be defrosted only by removing the auxiliary duct plate 19b. |
