ELECTRIC HEATER WITH ELASTIC SUPPORTING UNIT FOR ELASTICALLY HOLDING HEATING UNITS FROM LEFT AND RIGHT MEMBERS

摘要

PURPOSE: An electric heater is provided to prevent an electrical accident and a fire caused by electrical short-circuit in receiving a large quantity of conductive liquid and metal from the outside by improving a heating unit and to hold closely contacts between parts of the heating unit all the time by improving an integrally elastic supporting unit. CONSTITUTION: An electric heater is composed of a pair of left and right members(100,120) of the constant length facing each other; front and rear members(200,220) of the constant length for connecting the front and rear ends of the left and right members, respectively; a plurality of heating units(300) installed in an inner space formed by the left and right members and the front and rear members, mounted with a terminal unit(300a) projected through one of the front and rear members, and heated by electricity supplied from the outside; and an elastic supporting unit(400) for elastically holding the heating units from the left and right members.
