Description

  The present invention relates to a tank heat insulating structure and a hot water storage tank apparatus, and more particularly to a tank heat insulating structure for insulating a hot water storage tank and a hot water storage tank apparatus using the same.

  Conventionally, as a tank heat insulating structure, there is one in which a hot water storage tank is covered with a molded heat insulating material (see, for example, JP 2011-252659 A (Patent Document 1)). In the tank heat insulating structure, the molded heat insulating material is tightly fixed to the hot water storage tank by winding an annular tank reinforcing member around two shaped semicircular arc shaped heat insulating materials covering the hot water storage tank in the circumferential direction.

  However, in the above-described tank heat insulating structure, the joint portion of the two molded heat insulating materials that wraps the hot water tank has a problem that the strength is weak except for the portion where the tank reinforcing member is wound, and the heat radiation from the joint portion of the molded heat insulating material. As a result, there is a problem that the heat insulation performance is lowered.
