<p>PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating hot-water supplier improved in a thermal efficiency and durability. SOLUTION: A heat radiating fin 24 formed on the lower surface of a sealed lid 23 sealing the upper and opening 22 of a feed water tank 18 is arranged in a feed water passage 29, communicated with an inflow port 17 provided on the lid 16 for a waterproof case 3 to dissipate heat, generated from a main circuit 26 fixed to the sealed lid 23 into water to be heated before the water is supplied to the feed water tank 18 from the heat radiating fin 24 and is passed through the water proof case 3 whereby the main circuit 26 is cooled and direct heat exchange between the water to be heated can be effected and the thermal efficiency can be improved. Further, mechanical instrument, such as a fan or the like, is not employed whereby the durability of the hot-water supplier can be improved. An electromagnetic induction heating means 2 is received in the feed water tank 18 whereby the total structure of the hot-water supplier is compacted and it becomes favorable to the installation of the same.</p> |
