Refrigerator

Abstract

Abstract PURPOSE:To increase a cooling capacity by a simple construction and prevent frozen food from being melted by partitioning a duct into one for cooled air return and one for cooled air introduction with a partition wall and forming an opening of said cooled air return duct on the side of a refrigeration chamber on the side wall of said refrigeration chamber. CONSTITUTION:The air cooled with a cooling fan 15 and a vaporizer 14 cools a refrigeration chamber 10. The cooled air is partially introduced into a cover 19, a duct 28, an air intake section 29, responding with the temperature of a cold storage chamber 11 with a damper 17. The introduced air, after its temperature rises in the cold storage chamber 11, returns to the refrigeration chamber 10 by way of the opening of a cooled air return duct 30 and an opening 32 installed on the side of the refrigeration chamber 10, thus forming a cooling cycle. The cooled air introduced into the cold storage chamber 11 is heated with the return cooled air from the cold storage chamber 11 by way of a partition wall 31, which prevents the temperature in the cold storage chamber from dropping suddenly. Since the cooled air returning to the refrigeration chamber 10 is cooled reversely, the rise in the temperature in the refrigeration chamber can be minimized as well.
