<P>PROBLEM TO BE SOLVED: To solve poor work efficiency in assembling of a side plate, in which an assembling worker must perform operation while concerning about falling of the side plate, since the upper part of the side plate is not fixed in the assembled state. <P>SOLUTION: The hot water storage tank device includes: a hot water storage tank 1 for storing hot water; a molded heat insulating material 6 covering the tank 1; and an outer covering body 7 including at least a front plate 7a, lateral side plates 7d and 7e, a back plate 7c, a top plate 7f, and a bottom plate 4, and covering the molded heat insulating material 6. A hook part 9 turned down with a fixed space from the side plate reverse surface is provided at one end of each of the side plates 7d and 7e, and a receiving part 11 to which the hook part 9 is inserted when the side plate 7d, 7e is assembled in a regular position is provided at an end portion on one end side of the molded heat insulating material 6. Thus, the hook part 9 at the end of the side plate 7d, 7e is supported by the receiving part 11 at the end of the molded heat insulating material 6, whereby falling of the side plate 7d, 7e can be prevented. <P>COPYRIGHT: (C)2010,JPO&INPIT |
