Abstract

PROBLEM TO BE SOLVED: To easily wash a large pan by dispensing with arranging tableware by providing a washing means generating heat by induction heating in a sink partially having a nonmetallic part, and washing materials to be washed in the washing means by utilizing the convection of water generated by the generation of heat. SOLUTION: When a user arranges a metallic pan 12 as a material to be washed and materials to be washed stored in the metallic pan 12 in a sink 11 filled with water, and a high frequency current generator 15 is driven, a high frequency current is supplied to an induction heating coil 14, which generates a high frequency magnetic field by the high frequency current. The high frequency magnetic field interlinks with the metallic pan 12 because a part of the sink 11 is a nonmetallic part 13, so that the metallic pan 12 is induction-heated. Accordingly, water in the sink 11 becomes hot water to convect, and by motion of water caused by such convection, the metallic pan 12 and the materials to be washed in the metallic pan 12 are washed. At this time, in the case where a detergent is added to the water, a washing effect can be further heightened.
