Abstract

The present invention relates to an electric thermal insulation rice bowl coated on the inner surface of the carbon sheet heating element.

While pursuing human convenience and comfort, we make pots and pots suitable for the purpose and use only electric heaters through briquette fires, oil fires, and gas fires. It was a wasteful situation because it could not utilize heat energy efficiently and inadvertently released it into the atmosphere.

The electric heater, which is a heating element, is made of thin and long nichrome wire even when it is relatively energy-efficient, and it is closely connected to the lower outer wall of the rice bowl.Therefore, it is more wasteful of heat emitted to the outside than the heat transferred to the inside. Due to the concentrated fever, the side effects of partially burning rice and nurungji are large, while the product life is short.

The present invention uses a specially manufactured carbon sheet as a heating element to uniformly heat the inner surface of the rice bowl as a whole, and the heat emission is less outside the rice bowl, so the heat energy utilization is high.

The most important role of the electric insulation rice cooker is to produce electric rice cookers and cooking utensils using carbon sheet, which has higher heat energy use efficiency than nichrome wire products, but does not have side effects due to partial heat generation. It is easy to produce, and the electric current flows evenly distributed over the entire carbon sheet area and operates as a heating element, so there is almost no electric short-circuit or open-circuit failure rate, which is the biggest disadvantage of electric heaters. Provided is an electric thermos rice bowl coated with a carbon sheet heating element having a characteristic inside.
