Abstract

본 발명은 자성재료로 이루어지는 유도발열부를 갖는 용기에 대해 유도가열코일에 의해 유도전류를 발생시켜서 가열조리를 실시하도록 한 전기밥솥에 관한 것으로서,The present invention relates to an electric rice cooker in which an induction current is generated by an induction heating coil in a container having an induction heating part made of a magnetic material to perform heating cooking.

유도가열코일에 의한 발열효율과 열전달효율을 향상시킨 용기를 구성하여 가열조리의 열효율을 높이고 유도가열코일이나 히터의 구성을 간단하게 하며, 유도가열코일(16)은 용기(14)의 바닥면 둘레 가장자리부에 집중하여 설치되고, 용기(14)는 유도가열코일(16)에 대응하는 부분과 바닥면부와의 외부의 부분에 설치되는 자성 스테인레스재 등의 자성체 재료의 유도발열부(25)와, 저융점 합금층(26)을 통해서 내측에 설치되는 알루미늄합금 등의 열 양도체 재료로 이루어지는 열 전달부(27)로 구성되며, 열전달부(27)는 용융단조기술에 의해 유도발열체부(25)를 배치한 상태에서 용융한 열 양도체 재료를 성형함으로써 소정 형상으로 성형되는 것을 특징으로 하며, 유도가열코일(16)에 의한 발열동작에 필요한 부분에 유도발열부(25)를 설치하여 저가격화, 경량화를 도모하며, 열전도부(27)의 두께 길이를 바닥면부가 두껍게 되도록 하여 용기(14)내를 균일하게 가열할 수 있도록 하여 열적 효율의 향상을 도모한다.By constructing a container that improves the heating efficiency and heat transfer efficiency by the induction heating coil, the heating efficiency of the heating cooking is improved and the configuration of the induction heating coil or the heater is simplified, and the induction heating coil 16 is formed around the bottom surface of the container 14. The induction heating portion 25 of the magnetic material such as magnetic stainless steel, which is installed at the edge portion and is installed at the portion corresponding to the induction heating coil 16 and the portion outside the bottom surface portion, It consists of a heat transfer part 27 made of a heat-conducting material such as an aluminum alloy installed on the inside through the low melting point alloy layer 26, the heat transfer part 27 is the induction heating element portion 25 by the melting forging technique It is characterized in that it is molded into a predetermined shape by molding the molten heat conductor material in the arranged state, and the induction heating unit 25 is installed in a portion necessary for the heat generation operation by the induction heating coil 16, thereby reducing the cost and weight. To the plan, and a bottom surface length of the heat conductive thick portion 27 so that portion to be uniformly heated within the container 14 to be thicker to improve the thermal efficiency.
