The specific embodiment

Below, with reference to accompanying drawing, the utility model preferred embodiment carried out detailed explanation.At this, in the explanation of accompanying drawing, the symbol identical, the explanation of omission repetition to identical key element mark.

Fig. 1 is the sectional view of the general configuration of the related refrigerator of this embodiment of expression.Fig. 2 is the sketch map of general configuration of the refrigeration system of the related refrigerator of this embodiment of expression.Fig. 3 (a) and (b) are stereograms of general configuration of lid of the 2nd temperature sensor of the refrigerator of representing that respectively this embodiment is related.

Like Fig. 1 and shown in Figure 2, refrigerator 1 comprises refrigerator main body 10, refrigerating chamber PC, refrigerating chamber FC, the 3rd Room SC and refrigeration system 20.Refrigerating chamber PC is positioned at the upside of refrigerator main body 10, and refrigerating chamber FC is positioned at the downside of refrigerator main body 10, and the 3rd Room SC is between refrigerating chamber PC and refrigerating chamber FC.Refrigeration system 20 is set in the refrigerator main body 10, comprises compressor 201, condenser 202, triple valve 203, refrigerator evaporator 204, freezer evaporator 205 and the 3rd Room evaporimeter 206.
