[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of heating food and a pot, and more particularly, to the heating of foodstuffs that need to be heated for a long time at a high temperature when onions or sauces are present. The purpose is to pursue techniques related to methods and pots.

[0002]

2. Description of the Related Art Conventionally, when heating food, steam, gas, or electricity has been used, but in each case, only one type of heat source has been used. Of course,
The pot was also made of iron, stainless steel, a multilayer of iron and stainless steel, or one of copper. Also, there was no idea of cooling food after heating it.

[0003]

However, such conventional food heating methods and pots have the following problems.

First, when one type of heat source is used, the heating temperature may be too high, the heating temperature may be low, or the heating temperature may be immediately lowered, so that temperature control is difficult. Was. Also, there were cases where desired temperature control could not be performed. In particular, high temperatures could not be maintained only by the heat source using steam. Furthermore, it took a long time to raise the temperature only by the heat source using gas.

[0005] Second, considering the heat transfer, the material of the pot is reduced to 1
Attempting to form a high-conductivity material using only one type of material tends to result in an expensive pot.
Further, when only one kind of material is considered, there are various problems such as a material that easily rusts and a material that easily corrodes.

Third, when waiting for the temperature to drop after heating the food, it took a very long time for the temperature to drop naturally. In particular, when stir-fried, when the inside of the heated side began to burn, sometimes it was necessary to lower only the temperature of the burnt side to prevent burning, but it was not possible with conventional pots . An object of the present invention is to solve such a problem.
