PROBLEM TO BE SOLVED: To easily perform a demounting work of an electromagnetic induction coil in a refrigerating device including an electromagnetic induction heating unit.SOLUTION: A return pipe 3F has a curved pipe part 3F2 curved between its inlet and outlet. Further the return pipe 3F has a straight pipe part 3F1 extending from an inlet of the curved pipe part 3F2, and a straight pipe part 3F1 extending from an outlet of the curved pipe part 3F2. On the other hand, the electromagnetic induction heating unit 6A has the electromagnetic induction coil 68 for heating the straight pipe parts 3F1, 3F3 by electromagnetic induction. The electromagnetic induction heating coil 68 is wound around the straight pipe parts 3F1, 3F3. The electromagnetic induction coil 68 is mounted separatably from the return pipe 3F by being pulled out from the side of the curved pipe part 3F2. |
