<P>PROBLEM TO BE SOLVED: To provide a hot water storage device allowing easy piping connection to a connection port. <P>SOLUTION: The hot water storage device includes: a hot water storage tank 2 for storing hot water; a tank unit 1 for housing the hot water storage tank 2; a plurality of connection ports 49 which connects inner pipes 47 connected to the hot water storage tank 2 to supply water and hot water, with outer pipes 48 outside the tank unit 1; and a plate-like connection port metal fitting 46 which is horizontally disposed to cross the tank unit 1 for fixing the connection port 49. A polygonal seat-pushing part 50 which depresses the bottom part to protrude upward is formed on the connection port metal fitting 46. An insertion hole 52 through which a pipe part 51 of the connection port 49 is inserted from the bottom part is disposed. The connection port 49 is fixed to the connection port metal fitting 46 by means of a screw 54 while a seating part 53 of the connection port 49, having the same shape as the seat-pushing part is fitted into the seat-pushing part 50. The seat-pushing part 50 serves as a baffle to facilitate piping connection to the connection port 49. <P>COPYRIGHT: (C)2013,JPO&INPIT |
