<p><P>PROBLEM TO BE SOLVED: To provide a hot-water storage type hot-water supply device capable of securely preventing destruction of a boundary face of water and hot water in a laterally long hot-water storage tank. <P>SOLUTION: This hot-water supply device is provided with the hot-water storage tank 4 connected to a water in pipe 7 and a hot-water out pipe 5, storing hot water, and having a laterally long shape and a heating means 2 heating hot water in the hot-water storage tank 4. A water supply auxiliary pipe 9 communicating with the water in pipe 7 to supply water is provided in a bottom part of the hot-water storage tank 4 by extending it in the longitudinal direction. A water supply hole 11 composed of a plurality of small holes is provided on an upper side of the water supply auxiliary pipe 9. A direction change means 12 for directing the direction of water supply downward is provided above the water supply hole 11. Consequently, supply water rises always gently and causes no great disturbance in a water stream, the boundary face of water and hot water is not destructed and is kept in a satisfactory condition, and stored high temperature water can be supplied to the last drop. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
