<p><P>PROBLEM TO BE SOLVED: To provide a hot-water supply device capable of supplying hot water 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 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 whose one side is communicated with a water supply pipe 19 and whose other side is communicated with a hot-water supply pipe 21 is provided in the can body 1. A shape of the hot-water storage can body is made flat, its installation space is reduced, and it is easily installed in a small clearance. Since hot water is supplied through the heat exchanger for hot-water supply for exchanging heat with hot water in the hot-water storage can body, a booster pump is unnecessary to allow use with feeling of relief in a sanitary condition. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
