    Abstract: PURPOSE:To prevent a first refrigerating chamber from being excessively cooled, and to secure a predetermined volume of cold air in a second refrigerating chamber by a method wherein a cold-air return passage for the second refrigerating chamber, which is separated from an outlet passage leading cold air that has passed through a low-temperature chamber to the second refrigerating chamber, is provided within a third dividing wall, and this cold-air return passage is interconnected to a cold-air return duct which is provided at the back surface part of both low-temperature chamber and first refrigerating chamber, and which communicates to a cooling chamber. CONSTITUTION:An outlet passage 16 of cold air from a rear low-temperature chamber 5 of a third dividing wall to a second refrigerating chamber 7 is opened above a closed type container 17. A cold-air return duct 18 formed within the third dividing wall in a state separated from the outlet passage 16 is interconnected to a cold-air return duct 19 which is provided at the back surface part of both the low-temperature chamber 5 and a first refrigerating chamber 3 and communicates to a cooling chamber 8. After cold air discharged into the low-temperature chamber 5 via a damper thermostat 14b has been distributed and discharged to a portion above the container 17 accommodated in the second refrigerating chamber 7, the cold air returns to the cooling chamber 8 through the cold-air return duct 19, together with cold air discharged from outlet ports 13b via the damper thermostat 14b into a space between the outside of the container 17 and the inner wall of the second refrigerating chamber 7.

    Abstract: PURPOSE: To make convection of cold be conducted positively and thereby to make a temperature distribution in a third chamber uniform by a constitution wherein an intake of this chamber subjected to a temperature control different from the one for a freezing chamber and a refrigerating chamber is provided in the inside lateral wall of the third chamber and a return duct of the third chamber is made to communicate with the return duct of the refrigerating chamber. CONSTITUTION: A return duct 23 of a third chamber 3 provided in the lateral wall of the third chamber subjected to a temperature control different from the one for a freezing chamber 2 and a refrigerating chamber 4 is made to communicate with a return duct 22 of the refrigerating chamber through a side duct. Cold air cooled down by a cooler is discharged into the third chamber 3 from a discharge port provided in the ceiling of the chamber and flows in circulation to the cooler through the return duct 23 of the third chamber and the return duct 22 of the refrigerating chamber from an intake 26a provided in the inside lateral wall of the chamber. According to this constitution, return air of the third chamber is induced by the return air of the refrigerating chamber in a large circulation amount, also in this part in the right and the left inside the third chamber. Thereby convection of cold is conducted positively and a temperature distribution is made uniform.
