PROBLEM TO BE SOLVED: To provide a business-use refrigerator provided with defrosting function, in which even at the time a high-frequency heating chamber is not used for defrosting, the high-frequency heating chamber is used for preservation of frozen foods and eliminate a dead-space by circulating forcedly cold air of a freezing chamber to a high-frequency chamber, to keep it at a freezing temperature. SOLUTION: In the refrigerator, there are provided a freezing chamber 2, a high-frequency heating chamber 4 for defrosting of frozen foods and a device 5 for cooling a magnetron radiating microwaves and high-frequency generation. A vent hole 9 is provided in a common wall between the chambers 2 and 4 and passes the cold air but blocks high-frequency waves. A circulation duct 24 is provided to allow the chamber 2 to communication with the chamber 4. An evaporator 22 is provided in the duct 24. Further, a heating-chamber circulation fan 23, an outlet vent hole 9a passing cold air, but blocking high-frequency wave, and a cooling unit 20 are provided. |
