ELECTRIC SAKE WARMER SERVING ALSO AS WATER HEATER FOR MUG CUP

PROBLEM TO BE SOLVED: To perform use also as a water heater for a mug cup other than the sake (Japanese rice wine) warmer. SOLUTION: An annular projection piece 4 for mounting and fixing a heat transmitting plate 3 is formed around on an inner peripheral wall surface at the center part of a cylindrical casing 2 provided with an inner diameter slightly larger than the outer diameter of the annular projected line 1 of the bottom plate 1a of sake warmer S. The heat transmitting plate 3 is formed to turn a cross section to an almost inverse recessed shape for which an upper surface plate 6 is successively formed and fixed on the upper end face of a cylindrical body 5 provided with the outer diameter slightly smaller than the inner diameter of the casing 2, an annular recessed groove 9 for fitting the annular projected line of the bottom plate of the mug cup is engraved on the upper surface plate 6 and an opening part is formed on a lower part. Further, the lower end face of the cylindrical body 5 of the heat transmitting plate 3 is mounted and fixed on the projection piece 4 of the casing 2, an annular deep recessed groove 10 is formed between the casing 2 and the heat transmitting plate 3 and a sheathed heater is disposed on the lower surface of the upper surface plate 6 of the heat transmitting plate 3.
