Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2017/208738
Kind Code:
A1
Abstract:
The present invention comprises: a heat-insulating refrigerator body (1); a refrigeration chamber (3) that is formed within the refrigerator body; and a cold air duct (19) that is installed vertically on the back surface of the refrigeration chamber and that supplies cold air from a cooling chamber (9) into the refrigeration chamber. The cold air duct (19) is configured such that the wall thickness of a duct cold air inlet portion (21) connected to the cooling chamber (9) is greater than the wall thickness of a duct lower portion (22). Due to this configuration, the temperature of the cold air inlet portion (21), which is contacted first by the low-temperature cold air from the cooling chamber (9) and thereby strongly cooled, can be maintained at a relatively high temperature, and the foregoing makes it possible to suppress condensation in the cold air inlet portion (21) even if used in a high-temperature high-humidity region and under conditions where a relatively large amount of outside air enters into the refrigeration chamber (3).
