Multipurpose heating device using induction heating method using thermal plasma {MULTIPURPOSE HEATING DEVICE OF INDUCTION HEATING TYPE USING HEAT-PLASMA}

The present invention relates to a heating device for cooking food, and more particularly, it is possible to quickly and uniformly control heating by using thermal plasma, and a cooking value optimized for a cooking object or cooking utensil through radiant heating or convection heating. It is possible, and it relates to an induction heating type multipurpose heating device that minimizes the occurrence of harmful substances to the human body when using fried oil.

Various heating devices are used to cook food. Typically, a gas burner with strong thermal power and relatively easy handling is mainly used. The gas burner ignites a flame in the supplied gas after opening a fuel valve such as gas.

In such a gas burner, the gas discharged from the ignition flame generated by the rotation of the knob is burned to generate a flame, and the user adjusts the intensity of the flame by adjusting the amount of gas discharged by rotating the knob. In addition, the user can visually check the intensity of the flame and the cooking process of the food, and adjust the intensity of the flame by rotating the knob. In other words, the conventional gas burner controls the intensity of the flame while viewing the flame visually and the user's intuition.

However, since the gas burner is difficult to control the precise heating intensity, for example, when food is burned or is heated at a very weak temperature, the cooking time becomes very slow, and there is a limit to only cooking by direct heating of the heating source. have.

On the other hand, deep-fried dishes are widely used in general homes and restaurants because they have a wide selection of ingredients such as various fish, meat and vegetables, and can be cooked relatively easily. It is becoming more specialized and mass-produced.

For such fried food, a relatively simple cooking method is used, in which cooking oil is poured into an oil tank and fried ingredients are added while heating. In general, a simple form using a tank containing oil and heating a frying net. Is being utilized. In addition, devices such as temperature control and automatic oil supply have been developed and used to suit the situation of more specialized and mass-produced businesses.

The frying heating device widely used up to now is a burner that supplies combustion heat, the outer surface is in contact with oil, and the heat of the burner passes through the inside, and heats the oil by transferring the combustion heat of the burner to the oil. It is configured to include a heating tube.

In particular, it is well known by those skilled in the art that the oil temperature and cooking time are very important in a so-called fried cooking method in which food is fried in oil. For example, a so-called fried chicken cooking method in which chicken is fried in heated oil It is argued that heating the oil to 165℃ and cooking for 10 minutes is ideal.

In fact, when the food is fried and cooked, frozen or refrigerated food is added to cook it.In this process, the temperature of the oil decreases because cold food is introduced and absorbs heat.At this time, the temperature of the oil must be quickly maintained. If the temperature of the oil drops below the proper temperature due to the introduction of refrigerated or frozen food during the cooking process, the inside of the food may not be cooked. If the cooking time is lengthened to compensate for the low temperature, the surface of the food becomes crispy. Not only does the taste deteriorate, but also the productivity is degraded due to the fact that it is not done.

In addition, when frying a large amount of food continuously, the oil is always kept heated to a high temperature, so it takes little time to fry the food.However, when frying food intermittently according to the consumer's order, cold-cooled oil Since it takes a lot of time to heat the oven to high temperature, there is a disadvantage in that productivity is remarkably decreased.

However, in the frying apparatus that is mainly used up to now, since the heating tube is formed in a straight pipe shape, the combustion heat passes quickly, so the heat transfer efficiency is lowered, and accordingly, it takes a long time to heat the oil and the fuel efficiency is lowered. There are drawbacks.

In addition, the heating source of the conventional frying apparatus is a direct heating method, i.e., a frying vessel is provided on the upper side of the appliance body, and a heating wire is provided on the bottom of the frying vessel, so that the frying oil injected into the inside of the cylinder is In a way of heating, the temperature around the frying device increases, so that the working environment is poor, and this problem is further increased, especially in the case of summer. In addition, the conventional frying apparatus is used only for frying, and there has been a problem in that its usability is limited.
