REFRIGERATOR

PROBLEM TO BE SOLVED: To use a heater for preventing residual frost used also as a defrosting heater by disposing an end of the defrosting heater at a cooler side via a partition member under the cooler. SOLUTION: A cooler chamber 1 is formed at a back surface wall of a deep freezing chamber. And, a cooler 2 and a cold air return duct 3 of a cold storage chamber and vegetable chamber are provided in parallel via a partition plate 4 in the chamber 1. And, cold air is supplied by a cold air circulating fan 5 arranged at an upper part of the cooler 2 to be cooled, and again returned to the cooler 2 via the duct 3. Further, to prevent residual frost of the plate 4 of the duct 3, a defrosting tube heater 6 is arranged at a position for effecting thermal influence to the residual frost of the plate 4 at a lower part of the cooler 4. Thus, the heater 6 can be used also as a residual frost preventing heater.
