In addition, in the case of thawing the frozen water, if the phase change member is left at room temperature and the frozen water to be thawed is added to the thawed phase change member and left in a room temperature or a refrigerating chamber, the thawing time of the contents by latent heat of the phase change member Can be shortened.

 As such, when the separate thawing chamber is not used, there is an advantage that a separate space is not required in the refrigerator for thawing or freezing.

The thawing room unit of the refrigerator according to the present invention configured and operated as described above is directly thawed because the frozen water or the contents and the phase change member are directly contacted, and the thawing or freezing of the frozen product is performed using the latent heat of the phase change member. There is an effect that the time or freezing time is shortened.

And the thawing chamber unit of the refrigerator according to the present invention because the phase change member wraps and thaws the frozen water does not cause a sudden temperature change of the frozen water, thereby suppressing the evaporation of moisture in the frozen water and also the deterioration of the frozen water It has the advantage of preventing.

In addition, since the rapid freezing chamber unit of the refrigerator according to the present invention is directly contacted and frozen by the phase change member, there is an advantage that the contents are quickly frozen.

In addition, the thawing room unit of the refrigerator according to the present invention has the advantage that it is possible to perform the freezing or thawing in the same place by installing the cold / warm air inflow passage and the opening and closing mechanism.

In addition, since the warmth inflow passage of the thawing room unit of the refrigerator according to the present invention is connected with the machine room of the refrigerator, the warmer is supplied, and thus, the overall efficiency of the refrigerator due to a drop in the machine room temperature is increased.
