And a lid 8 that can be freely opened and closed on the shoulder of the container 13 and hermetically closes the upper end opening of the vacuum double container 3.

However, in this type of electric water heater, when the electric water heater body that is a liquid supply container falls, the liquid in the vacuum double container that is the inner container flows out from the discharge port through the discharge path.
That is, at the time of falling, the water stop valve in the discharge passage prevents the outflow to some extent, but does not completely stop the water, but slightly outflows and wets the installation place. In particular, when the fitting between the electric water heater body and the lid is poor, the liquid in the vacuum double container flows out at a stretch.

Furthermore, the external electric power may be applied to the control board in the electric water heater body while the power cord is attached from the electric water heater body.
Therefore, there is a high possibility that the power cord connecting portion, the control board connecting portion, etc. get wet and there is a risk of electric leakage or electric shock, resulting in a very high risk.
