<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply device not consuming electric power in switching flow channels. <P>SOLUTION: This hot water supply device includes a hot water storage tank 1 for storing hot water, a heating means 2 for heating the hot water in the hot water storage tank 1, and a flow channel switching means 100 for distributing the hot water heated by the heating means 2 to an upper section or a lower section of the hot water storage tank 1, and a shape-memory spring and a closing valve are used as the flow channel switching means 100. As flow channels are switched according to a temperature of the hot water heated by the heating means, electric power is not consumed in switching the flow channels, and power-saving and cost reduction are achieved. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
