A storage box with a thermoelement is disclosed. This storage box is operable in a frozen-storage mode operation, in addition to a cool-storage mode and a hot-storage mode. During a cool-storage mode operation of the storage box, the main compartment ( ) is primarily cooled by a main thermoelement ( ) to be kept at a low temperature. The temperature difference between the areas around the two junctions ( ) of the sub-thermoelement ( ) of a sub-storage unit ( ) installed within the main compartment ( ) is sufficiently smaller than that between the areas around the two junctions of the main thermoelement irrespective of a consideration of an addition of heat produced from heat exchanging units provided at the two junctions of each thermoelement. The sub-thermoelement ( ) is thus significantly improved in its cooling capacity. The temperature of the sub-compartment ( ) of the sub-storage unit ( ) is thus reduced lower than 0&deg; C., and so the sub-compartment is kept in a frozen-storage mode. The sub-storage unit ( ) is removable from the main compartment ( ), thus allowing a user to use it independently from the storage box in, for example, a car.

Defrosting apparatus for refrigerators and method for controlling the

A refrigerator has separate refrigerating and freezing compartments, an evaporator and fan for each compartment, and a compressor connected to the evaporators. A controller determines whether the refrigerator is in a normal mode or an overload mode, depending upon (i) the ambient temperature in the room where the refrigerator is disposed, (ii) the number of times the refrigerator door is opened per unit time, and (iii) the total time period in which the door is in an open state per unit time. In a normal mode, the compressor and both fans are operated simultaneously under the control of the temperature in the freezing compartment. In an overload mode, the two fans are operated independently, under the control of the respective temperatures in the freezing and refrigerating compartments.

Methods and apparatus for controlling a refrigerator in normal and

A refrigerator has freezing and refrigerating compartments arranged above and below one another. A hollow duct extends vertically through said freezing and refrigerating compartments and receives a flow of cool air at its upper end. The duct includes vertically spaced holes through which the cool air is discharged into the freezing and refrigerating compartments. The duct is freely rotatable about its longitudinal axis and carries fins arranged at the discharge holes such that the discharging cool air impinges against the fins to cause the duct to rotate.
