Title:
REFRIGERATOR-FREEZER
Document Type and Number:
Japanese Patent JP2004232879
Kind Code:
A
Abstract:

To enhance cooling efficiency by equalizing a temperature distribution in a cooling chamber of a refrigerator-freezer to lower energy loss, improving a ventilation property in the cooling chamber independent of the quantity and disposition of an object to be cooled, and reducing heat leakage from an outside and a wall face of the cooling chamber into an inside of the cooling chamber.

In the refrigerator-freezer, cooled air cooled by a cooling device 1 is forwarded to a freezing chamber ceiling surface air passage 34 communicating with a freezing chamber 31 by a blower fan 3, and blown into the freezing chamber 31 through a propeller fan 9 provided inside a wall of a freezing chamber ceiling surface 26. The cooled air is blown into the freezing chamber 31 changing its flow direction due to blowing force of the blower fan 3 and makes airflow stirring the air in the freezing chamber. The temperature distribution generated in the freezing chamber 31 is equalized by improving the ventilation property in a cooled object storing container. A gasket and the inside of the freezing chamber are shielded with a shielding member through a space to reduce the heat leakage in the vicinity of the gasket.
