<p><P>PROBLEM TO BE SOLVED: To stably hold a hot water storage tank in a casing during transport in a hot water storage tank unit in which the hot water storage tank is erected and fixed in the casing. <P>SOLUTION: The hot water storage tank unit 1 includes: a hot water storage tank 2; a substantially rectangular casing 3 storing the hot water storage tank 2 in an erect manner; and a plurality of tank holding fittings 6 for fixing the vicinity of the upper part of the hot water storage tank 2 to the casing 3. The tank holding fittings 6 respectively have bent surfaces 61, 62 formed by bending a substantially rectangular flat plate 60 like Z-shape, one bent surface 61 is fixed to the side plates 32, 33 of the casing 3, and an end side 62a of the other bent surface 62 is fixed to the side surface of the hot water storage tank 2. Thus, stress applied to each fixed part of the casing 3 and the hot water storage tank 2 due to vibration of the hot water storage tank 2 is absorbed by deformation of a narrow linear surface joint part by the end side 62a of the bent surface 62 of the tank holding fitting 6. Therefore, the hot water storage tank 2 can be stably held in the casing 3 and breakage of each fixed part can be prevented during the transport. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
