実に防止されるのである。(Function) However, since the electric heater 2 is attached to the hot water storage tank 1 in a cantilevered manner, this attachment part becomes loose and the tip of the heater 2 is attached to the tank 1.
Even if the heating element 2c is tilted toward the bottom wall side of the heater 2 and comes into contact with the bottom wall, by providing the heating element 2c in the middle of the heater 2, the inner part of the tank where the heating element 2c is not disposed can be removed. The tip of the side does not reach a high temperature unlike when the heating element 2c directly generates heat,
Moreover, since the distal end portion is formed with a heat insulating material 4 that protrudes radially outward with respect to its outer circumferential surface,
The outer circumferential surface of the tip is covered with a heat insulating layer equal to the protruding thickness of the heat insulating material 4, so that the tip of the heater 2 does not come into direct contact with the bottom wall of the tank 1, and the heat insulating material Therefore, the heat insulating material 4 formed on the outer circumferential surface of the tip portion blocks heat transfer from the tip portion, and furthermore, this protrusion height Since the electric heater 2 can be separated from the tank 1 by that much, heat transfer from the tip to the bottom wall of the tank 1 can be more effectively prevented.
Damage, deformation, and fire due to heating of the tank 1 are reliably prevented.
