ELECTRIC HOT WATER RESERVING CONTAINER

摘要

PROBLEM TO BE SOLVED: To obtain sufficient heat insulation at a low cost. SOLUTION: A heat insulating cover 71 is provided on the outside of at least the trunk part of an inner container 2 by simple structure integrally forming with a shoulder member 3 connecting the mouth parts of an external case 1 and the container 2 with each other or supporting by the member 3. Then, a first heat insulating space 72 is formed between this cover 71 and the container 2 and a second heat insulating space 73 is formed between the cover 71 and the case 1 to improve heat insulation.
