<p><P>PROBLEM TO BE SOLVED: To provide an energy-saving electric water heater and an electric hot water supply method that are simple in structure, low in cost and low in power consumption. <P>SOLUTION: The electric water heater 10 has an upper heating part 14 and a cold/warm water mixing part 16 in an upper part 12A and a lower part 12C of a hot water storage tank 12 respectively, and when boiling water in the upper heating part reaches a given value, introduces the boiling water into the cold/warm water mixing part to mix it with cold water and generate warm water. The warm water is introduced uniformly to the lower part and a middle part of the hot water storage tank via a diffusion member 24 to generate cold/warm water, which is supplied to the upper heating part. Boiling water can be thus generated efficiently. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
