<P>PROBLEM TO BE SOLVED: To prevent the tapping of high temperature hot water when supplied in a trace amount while preventing the turn-around of city water to the hot water side of a hot water supply mixing valve. <P>SOLUTION: This storage type hot water supply device comprises a tapping pipe 111 for taking hot water out of the upper part of a hot water storage tank 101. Herein, to reduce the resistance of a flow path from a branch point T of a flow path on the tapping pipe 111, branching to the side of a faucet 124 or a bathtub 113, as a basic point, to the side of the faucet 124 rather than the side of the bathtub 113, the pipe diameter of the tapping pipe 111 ranging from the branch point T to the side of the faucet 124 is made longer than the pipe diameter of the tapping pipe 11 ranging from the branch point T to the side of the bathtub 113. Besides, a check valve 129 is provided on the tapping pipe 111 ranging from the branch point T to the side of the faucet 124. <P>COPYRIGHT: (C)2007,JPO&INPIT |
