Title:
IMMERSION HEATER FOR WATER TANK
Document Type and Number:
Japanese Patent JPH0325883
Kind Code:
A
Abstract:
PURPOSE: To confirm the operation of a temperature controller with an AC plug in hand by integrating an operation lamp into the AC plug.
CONSTITUTION: In a water tank immersion heater immersed and used in water in which a temperature controller 6, a heater 2, and a temperature sensor 1 are integrated into a protecting cylinder 7, an operation lamp 3 is integrated into an AC plug 4 so that the operation of the temperature controller can be detected at hand. Further, by integrating the temperature controller 6, the heater 2, and the temperature sensor 1 into the protecting cylinder 7, one electric wiring suffices, resulting in a reduction in the possibility of electric shock.
