Combination of a bottom of a pan and a heating means

Abstract

A combination of a bottom of a pan and a heating device comprises a pan, an aluminum alloy plate and an electric heating member welded to a bottom of the pan by means of instantaneous welding, a thermostatic circuit fixed to the bottom of the pan for keeping the pan at a constant temperature when energized, a mounting plate integrally formed with the aluminum alloy plate, and a temperature-control switch fixed to the mounting plate. A switch is mounted to a rear of the temperature-control switch to thereby switch the temperature-control switch between the electric heating member and the thermostatic circuit. An activating member is operably connected to the switch in a manner that the electric heating member is turned on when the activating member is manually activated and that the electric heating member is turned off and the thermostatic circuit is energized when a food in the pan is well cooked or heated to a predetermined temperature.
