A Refrigerator Having Deeply Low Temperature Freezer

摘要

The present invention relates to a refrigerator to which a deeply low freezing compartment structure is applied in which a heat exchange between a deeply low freezing space and a freezing chamber inner space is surely prevented, the cost for installing a heat insulating material is reduced, the freezing chamber has no problem in a refrigerating flow even when the deeply low temperature freezing compartment is installed in the freezing chamber, and volumes of the freezing chamber and the deeply low freezing compartment by minimizing a volume occupied of a structure for insulation occupied in the freezing chamber. The deeply low freezing compartment is installed at an upper portion of the freezing chamber and spaced apart from a ceiling of the freezing chamber at a predetermined distance, in which a flow guide surface is provided at a rear end of the deeply low freezing compartment, thereby facilitating a cold air flow. In addition, the deeply low freezing compartment is buried in a deeply low freezing compartment wall portion to which a structure of installing the deeply low freezing compartment in the freezing chamber is applied or to which a guide portion for a drawer operation of the deeply low freezing compartment is applied, and a foamed insulating material is injected into a remaining area. Further, vacuum insulation panel insulating material is applied to a deeply low freezing compartment wall configured to be thin, so that a deeply low freezing space is secured.
