This device has various operation modes, and executes various controls by incorporating a control circuit board including an electronic control circuit such as a microcomputer on which electronic components are mounted. Such a control circuit board needs to be protected from the environment such as heat and water leakage in the body.

電気貯湯容器が複雑で高価なものになる問題もある。However, arranging the circuit box in the bottom space inside the container itself makes it difficult to make the height ratio of the inner container smaller than the height of the container. It is a cause that capacity efficiency cannot be improved. Further, the heater is formed in a disk shape from the viewpoint of the heating efficiency and the like, and is provided so as to be applied to the bottom lower surface of the inner container. In the electric hot water storage container having such a structure, since the circuit box faces the heater, it is necessary to employ a heat insulating structure such as a metal heat shield plate or a heat insulating gap between the circuit box and the heater. The capacity efficiency of the body is further reduced as more space can be created under the bottom. In addition, the height of the body is unnecessarily high and bulky. Further, the heat insulation structure as described above has a problem that the electric hot water storage container becomes complicated and expensive.

い。As described above, since the circuit box 33 is vertically disposed between the outer body A of the container 1 and the body 1a of the inner container 15, the vertical space can be obtained without particularly increasing the gap between the bodies. The heater 11 is applied to the inside lower surface of the inner container 15 as well as the space for accommodating the circuit box 33 in the outer space A of the container 1 and the bottom space of the inner container 15. However, since it does not face this heater, no space for heat insulation between the heater 11 is required.
Can be short and not bulky, and have high capacity efficiency. In addition, as described above, the structure is simplified by eliminating the need for the heat insulating structure.
Including the case where the circuit box 33 is integrally formed with any part of the throat, the circuit box 33 is integrally formed with the existing member, and the number of components does not increase, so that the cost does not increase.

る。According to the electric hot water storage container of the first aspect of the present invention, the control circuit board which functions by being connected to the operation panel and the heater is vertically arranged between the outer casing of the body and the body of the inner vessel. It is arranged so that it can be positioned vertically without making the normal gap between the body parts particularly large, and in addition to the space for providing the control circuit board in the bottom space of the exterior body and the inner container, as well as in the bottom of the body. Since there is no need for a space for heat insulation between the heater and the heater, the height and height of the container can be reduced, and the capacity can be increased. Moreover, as described above, the structure is simplified as much as the heat insulating structure is not required.
