The present invention relates to a freezer supercooling housed objects, and the freezer including: a main body including a cooling chamber, in which multiple shelves on which the objects are mounted are installed, and a door opening or closing the side of the cooling chamber; an evaporator cooling air in the cooling chamber with being installed at the upper side of the cooling chamber; a cooling duct housing the evaporator; an air ventilation fan feeding the air in the cooling chamber to the evaporator with being placed in the cooling duct and in the front of the evaporator; a cooled air feeding duct inducing the air, which has been cooled after passing through from the cooling duct to the evaporator, to the floor of the cooling chamber with being connected to the cooling duct; multiple extended ducts, which protrudes from the cooled air feeding duct in the direction of positioning the door, respectively feeds the cooled air from the upper sides of the objects mounted on the shelves. Therefore, the present invention maintains the internal temperature of the freezer with installing the extended ducts uniformly discharging the cooled air to a front part in which the door of the freezer is installed, thereby not only uniformly supercooling the objects, but also improving supercooling efficiency with reducing time for feeding the cooled air by directly feeding the cooled air from the upper sides of the objects through the extended ducts. |
