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.

This product uses a specially manufactured carbon sheet as a heating element to uniformly heat the inside of the rice bowl.

The outside of the rice bowl is less heat emission, the heat energy utilization efficiency is high.

As a heating element that plays an important role in the electric insulation rice cooker, the electric rice cooker and cooking utensils are manufactured using carbon sheet, which has higher heat energy use efficiency than the nichrome wire product, but does not have side effects due to partial heat generation.

It is easy to insulate and insulate, and it is easy to produce, and the electric current is distributed evenly over the entire area of the carbon sheet, which acts as a heating element. It is provided with an electric thermal insulation bowl coated on the inner surface of the carbon sheet heating element having a long and high efficiency of thermal energy.
