CERAMIC HEATER FOR INDEPENDENTLY CONTROLLING MIDDLE REGION

The present invention relates to a ceramic heater for independently controlling a middle region, and more specifically, to a ceramic heater comprising: a center-edge heating element provided at a position corresponding to a center region and an edge region of a heating surface of the ceramic heater; and a middle heating element provided at a position corresponding to a middle region which is surrounded by the center region and the edge region of the heating surface of the ceramic heater, and thus the present invention has an effect whereby the respective temperatures of three divided regions may be controlled by two power devices. 本发明涉及一种中间区域独立控制陶瓷加热器，更详细而言，涉及一种包括在与陶瓷加热器加热面的中央区域和边缘区域对应的位置提供的中心-边缘(CENTER-EDGE)发热体及在与被陶瓷加热器加热面的中央区域和边缘区域包围的中间区域对应的位置提供的中间(MIDDLE)发热体的陶瓷加热器，具有可以利用2个电源装置控制3个分割的区域的温度的效果。
