ABSTRACT:
An electric stove for kitchen has a base, an outer ring frame, an electric hot-plate and fixed supports, etc. The main characteristic of the present invention is in that the outer ring frame is easy to be exactly locked on the circular groove of the base by penetrating screws into bigger bored bakelite washers, bigger holes of the flanges of the circular groove and another bigger bored bakelite washers in order and then screwing up nuts tightly, by which the generated hollow space between bakelite washers and nuts being the result of screwing the circular groove of the base and the outer ring frame in suspension can reach better effect in heat insulation. Moreover, the simple method of screwing a calorific member and a protruding iron cover covering outside the calorific member to the electric hot-plate is very helpful for repairmen to fix broken-down calorific members.
