ヒーターの過熱防止装置。[Scope of Claim for Utility Model Registration] (1) Overheating of a submerged heater installed in a liquid storage tank to prevent it from burning out due to energization in an exposed state with no liquid present. In the prevention device, an upper bottom holder is provided in the bottom plate portion of the liquid storage tank, the receiving plate portion supporting at least a part of the submerged heater being made of a metal material with good thermal conductivity and having a recessed bottom plate shape. A part of the submerged heater is brought into direct contact with the upper surface of the receiving plate part of the upper bottom cradle, and is pressed and fixed by a tightening means, and the cradle receiving plate part is placed in the recess opened on the lower surface of the upper bottom pedestal. A bimetallic switch for preventing overheating of the heater is installed on the bottom surface of the heater so that the heat sensing part is in contact with the heater, and this bimetallic switch is electrically connected in series to the energizing circuit of the heater.
An overheat prevention device for a submerged heater, characterized in that a bimetal switch is activated to automatically cut off a heater energization circuit before the heater becomes red hot. (2) The tightening means for pressing and fixing a part of the heater onto the upper base holder has a plurality of stud bolts erected on the receiving plate of the upper base holder and an insertion hole for the stud bolts. and a heater fastening plate that presses and fixes a part of the heater between it and the pedestal receiving plate part by tightening a nut screwed into the bolt thread part. An overheating prevention device for a submerged heater according to claim 1 of the utility model registration claim.
