This application is a Continuation of application Ser. No. 10/769,814, filed on Feb. 3, 2004, the entire contents of which are hereby incorporated by reference and for which priority is claimed under 35 U.S.C. § 120.
The refrigerating chamber is maintained at about 3° C.˜4° C. for long time fresh storage of food and vegetable, and the freezing chamber is maintained at a subzero temperature for long time storage of meat and fish in a frozen state, and making and storage of ice pieces. In general, the refrigerating chamber has a volume greater than the freezing chamber, and the freezing chamber is allocated over the refrigerating chamber.
In the meantime, the refrigerator of the present invention is provided, not only with the water dispenser 3 for supplying cold water, but also an icemaker 10 for producing and supplying a plurality of ice pieces. The icemaker 10 will be described in more detail with reference to the attached drawings. For reference, FIGS. 2 and FIG. 3 illustrate an icemaker and an ice container provided to the refrigerator in FIG. 1, and FIG. 4 illustrates a diagram showing operations of them.
The icemaker 10 produces ice by using the cold air supplied to the cavity 61, and the. produced ice is stored in the ice container 20. Since the cold air is supplied to the cavity 61 continuously, the ice stored in the ice container 20 does not melt.
The third duct 90 includes a third part 91 provided to the door 52 a and a fourth part 95 provided to the sidewall of the cabinet 50. The third part 91 is in communication with the cavity 61, and the fourth part 95 makes the freezing-chamber 51 and the third part 91 in communication. The third part 91 and the fourth part 95 are connected to each other when the door 52 a is closed, and there is a gasket 90 a at a connection part of the third part 91 and the fourth part 95.
