  In the hot water storage tank unit as described above, a large exterior plate is used. In particular, in a thin hot water storage tank unit for narrow space installation in which two hot water storage tanks are stored side by side, the size of the right side plate and the left side plate becomes very large.

  For this reason, when assembling the exterior plate in the hot water storage tank unit, it is necessary for another worker to fix the exterior plate with screws while one auxiliary worker holds the exterior plate so that the side plate does not fall down. Alternatively, the operator needs to fix the exterior plate with screws in a state where the exterior plate is pressed by the support member so that the side plate does not fall down. In addition, when the side plate is thinned for cost reduction and weight reduction, the large side plate is easily bent, and there is a problem that workability is further deteriorated.

  In addition, since the hot water storage tank unit described in Patent Document 1 includes a bracket for fixing the exterior plate that fixes the exterior plate, there is a problem that the configuration is complicated.

  The present invention has been made in view of the above problems, and an object of the present invention is to enable easy assembly of an exterior plate with a simpler configuration.

  In order to achieve the above object, the invention described in claim 1 includes a hot water storage tank (1, 2) for storing hot water, a heat insulating material (10) for covering the hot water tank, and an exterior plate (20 to 70) for covering the heat insulating material. The exterior plate has side plates (40, 50) disposed on the sides of the hot water storage tank, and the heat insulating material has recesses (14a, 14b) recessed from the surface. The side plate includes a plate-like main body surface (40c, 50c) and a hooking portion (40a, 50a) that protrudes from the main body surface toward the heat insulating material and hooks into the recess.

  According to such a configuration, the worker can assemble the side plate in a state in which the hook portion formed on the side plate is hooked on the concave portion of the heat insulating material. Assembly can be performed.

  In addition, the code | symbol in the bracket | parenthesis of each means described in this column and the claim shows the correspondence with the specific means as described in embodiment mentioned later.
