<P>PROBLEM TO BE SOLVED: To provide a thawing tank in which an ice can be promptly thawed by effectively transmitting the heat of the heating means to the ice when the stored water is frozen and become ice. <P>SOLUTION: One of the heat sinks 3, 4 with which a heater is incorporated is movement freely arranged in the water tank 1. When the water 2 stored in the water tank 1 is frozen and become ice 11, this ice 11 is pinched by the heat sinks 3, 4 and the heat of the heater incorporated with the heat sinks 3, 4 is transmitted to the ice 11 and the ice is thawed. When thawing of the ice 11 is progressed and the ice becomes small, the heat sink 4 is moved so as to narrow the space between the heat sinks 3, 4, and to make the not thawed ice 11 always contact the heat sinks 3, 4. Thereby, the heat of the heater is transmitted effectively to the ice 11 not thawed and prompt thawing can be performed. <P>COPYRIGHT: (C)2004,JPO |
