The conventional food heating means belonging to this technical field is characterized in that a high pressure gas is blown out from a high pressure gas as a raw material and then reduced to a gas to be jetted to heat the cooking vessel containing the food by the ignited gas, There has been a gas stove that heats the food inserted into the cooking container by heating and transfers the heat to the cooking container, and a microwave oven that heats the food by heating the cooking container using electromagnetic waves A gas stove such as the above-mentioned electronic stove has an advantage that it can cook food within a short time, but there is a disadvantage in that a large amount of heat loss is generated due to a low heating temperature to be heated in the cooking pot rather than a heating temperature of the gas stove, Because gas fire is extinguished, safety accident caused by gas leakage or overheating of gas fire There is a problem that a serious problem such as a fire is generated and it requires careful attention. In the latter microwave oven, there is an advantage that it is easy to use. On the other hand, when the cooking vessel is metallic, And there is a problem that the cooking vessel is inevitably forced to use a cooking vessel made of porcelain, and the heating of the cooking vessel is dependent on electromagnetic waves, resulting in an excessive power consumption and a problem that the size of the vessel is limited to a small vessel .

At this time, in the case of the above-mentioned gas stove, only the heat amount of about 30 ~ 40% is delivered directly to the cooking vessel, about 60 ~ 70% is lost to the outside, and the temperature inside the kitchen As a result, the chef who cooks a lot of sweat, so that the sweat and the foreign impurities are introduced into the food and the food is not cleaned.

According to the type of food, the temperature and the time for cooking the food varies according to the years of experience and proficiency of the chefs, and the kinds of the dishes are various kinds of cooking such as boiling, roasting, There are many kinds of cooking methods like this, so even if the same ingredients are used, the skilled chefs cook a lot of different tastes for each individual. However, a beginner who does not cook a lot of dishes tends to have a lot of time And the dish which can not produce the unpleasant taste has to be eaten in a state without taste.

In the case of a large-sized restaurant having a large amount of food to be cooked, it is necessary to boil the food at all times. Therefore, the use of a microwave oven for cooking a small amount of food such as the latter is inevitably less worthy of use than a gas stove. A large amount of heat loss is generated by heating, and the continuous heating of the gas heat generates a closed end which can not store the food at a constant temperature at all times.

[Technical Problem]

The present invention has been made in order to solve the problems caused by the conventional food heating means as described above.
