<p><P>PROBLEM TO BE SOLVED: To provide a hot-water supply device capable of supplying hot water efficiently in a hygienic condition by utilizing a hot-water storage can body of atmosphere opening type having no restriction on its shape. <P>SOLUTION: The hot-water storage can body 1 for storing hot water heated by a heating means 2 is provided. A water supply pipe 7 with at least a water supply solenoid valve 11 is communicated with the can body 1. The water supply solenoid valve 11 is opened or closed in accordance with a water level by a water level detection means 14 for detecting a water level in the can body 1 to constantly hold a constant water level. An atmosphere opening chamber 16 is formed in an upper part of the can body 1. A heat exchanger 17 for hot-water supply positioned from a lower part to an upper part in hot water in the can body 1 is provided. A hot-water supply pipe 21 is connected with an upper end part of the heat exchanger 17 for hot-water supply, and a plurality of supply pipes 28 to 31 branched from a water supply pipe 19 and opening/closing means 32 to 35 for selectively opening/closing the supply pipes 28 to 31 are connected with a part below a connection part of the hot-water supply pipe 21 to change a heat absorption position of the heat exchanger 17 for hot-water supply in accordance with rise of a high temperature water tank in the can body 1, thereby realizing efficient and hygienic hot-water supply. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
