Claims (1)

[Scope of Claim for Utility Model Registration] (1) A refrigerator partitioned into three chambers: a top chamber, an intermediate chamber, and a bottom chamber, an upper cold air outlet opening on the side wall of the top chamber, and a side wall of the middle chamber. A middle cold air outlet opening at the wall surface, a lower cold air outlet opening at the bottom of the lowest chamber, an upper cold air intake opening opening at the back surface of the top chamber, and an upper cold air intake opening opening at the rear surface of the middle chamber and the rear surface of the lowest chamber. a middle and lower cold air inlet, an evaporator provided at the lower part of the refrigerator, and a partition plate that partitions the evaporator into three parts, a first part, a second part, and a third part;
a first ventilation duct extending along the periphery of the cooling store and communicating the upper cold air outlet with the cold air blowing side of the first part of the evaporator; a first reduct duct having an opening communicating with the cold air intake side of the first part of the evaporator;
a second ventilation duct extending along the periphery of the cooling store and communicating the middle cold air outlet with the cold air blowing side of the second part of the evaporator; and a second ventilation duct extending along the periphery of the cooling store and connecting the lower air outlet a third ventilation duct that communicates with the cold air blowing side of the third section of the evaporator; a cold air collection duct that extends along the periphery of the cooling store and collects cold air that enters from the middle and lower cold air intake; A refrigerated container comprising: a second return duct extending along the periphery of the refrigerator and communicating the cold air collection duct with cold air intake sides of the second and third parts of the evaporator. (2) The first ventilation duct has a first chamber in the upper part, and the first chamber includes a first ventilation port that communicates the first chamber with the first ventilation duct, and an air blower for the external cooling unit. a second vent for inserting a duct; a third vent for passing cold air in the first chamber to the first ventilation duct;
The second vent is provided with a first damper that is openable and closable and closes the first vent when it is in an open state, and the first reduct duct has a second chamber at an upper portion, and the second damper includes a fourth vent for inserting the reduct of the external cooling unit, a fifth vent for passing the cold air that has passed through the upper cold air intake into the second chamber, and a vent for opening and closing the fourth vent. The cold air collecting duct has a third chamber in upper and lower stages in the upper part thereof, and the third chamber is provided with a second damper which is freely disposed. a sixth vent provided in the lower stage of the third chamber; a seventh vent provided to communicate the upper and lower stages of the third chamber;
The sixth vent is provided with a third damper which is freely openable and closable and which blocks the seventh vent when it is in the open state, and the second reduct duct is provided with upper and lower parts at the top.
The fourth chamber has an eighth vent provided in the lower part of the fourth chamber for inserting the air duct of the external cooling unit, and the fourth chamber has an eighth vent provided in the lower part of the fourth chamber, and the fourth chamber has an eighth vent provided in the lower part of the fourth chamber for inserting the air duct of the external cooling unit. a ninth vent provided to communicate with the upper part of the third chamber and the upper part of the fourth chamber;
2. The cooling container according to claim 1, wherein the cooling container further comprises a fourth damper which is freely openable and closable at the ventilation port and closes the ninth ventilation port when the ninth ventilation port is in the open state.
