Abstract
Description
The present invention relates to a dual heating cooker. More particularly, the present invention relates to a dual heating cooker that applies heat to both the direct heat transfer system and the indirect heat transfer system to uniformly transfer heat across the entire cooking area and maintains an optimal temperature condition suitable for cooking food.
In general, a device for cooking food such as meat or fish roasts or potatoes is provided in a relatively flat, low-profile fan shape in which foods are thinly spread so as to be cooked as quickly as possible.
Such a pan-type cooking apparatus is manufactured and used by various methods. For example, a manufacturing method using a casting method using cast iron or aluminum or a drawing process of a press using a metal plate material is widely performed.
The fan-type cooking apparatus manufactured by this manufacturing method directly feeds the combustion heat to the bottom surface of the cooking apparatus, and the food is cooked. At this time, the combustion heat directly transmitted to the bottom surface of the cooking apparatus is heated locally Therefore, the heat conduction is not uniform.
That is, since heat is concentrated only on a partial area of the conventional cookware of the direct heat transfer type, only the surface of the cooking utensil that is in contact with the cooking utensil is rapidly burned before the cooked food is cooked as a whole, There is a problem that the steam or the smoke is excessively generated and the efficiency of the cooking is lowered.
In recent years, a cooking apparatus has been developed in which a double wall structure in which a bottom portion is provided with a space in which air can be retained is provided, and the air heated in this space acts as a heat transfer medium to indirectly heat the cooking surface touched by the food .
Such an indirect heating method has the advantage that the cooking operation can be performed more efficiently and the burning of the food to be cooked can be prevented because the heat is evenly transmitted to the cooking device. However, It takes a long time to rise to a temperature and a considerable time is required to cook the food itself, which leads to an increase in the overall cooking time.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a dual heating cooking appliance in which heat is uniformly transferred from a heating means to a cooking surface by applying both a direct heat transfer method and an indirect heat transfer method.
It is another object of the present invention to further extend the service life of the double heating cooker because the lower plate coupled to the main body bottom plate of the double heating cooker is further firmly coupled to prevent it from being arbitrarily separated.
In order to achieve the above-mentioned object, the present invention provides a cooking apparatus comprising: a main body bottom plate having a top surface as a cooking surface; a heating space portion disposed on a bottom surface of the main body bottom plate and recessed toward the top; A body portion having a bottom edge protruding downward from the body bottom plate; And a lower surface of the lower plate covering the open lower portion of the heating space in a state in which the upper surface is in contact with the thermally conductive pin and having a first coupling protrusion protruding from the upper surface of the side surface so that the upper diameter of the side surface is larger than the lower diameter Wherein the main body and the lower plate are joined together by plastic deformation so that the joining rim is pressed against the first joining jaw in a state in which the side surface of the bottom plate faces the inside of the joining rim. Provide cooking utensils.
At this time, the main body has a binding pin protruding from the bottom surface of the main body bottom plate, the bottom plate has the binding pin penetrated, the second binding jaw protrudes inward in the upper side, And a pin through hole formed in a narrower multi-step structure, and the binding pin is plastically deformed to press the second binding jaw by press working.
In addition, the main body includes a central binding portion protruding from the center of the bottom of the main body bottom plate, the middle binding portion penetrates through the bottom plate, a third binding jaw protrudes inward in the upper side, And a central through hole formed in a multi-end structure narrower than the diameter, and the central binding portion is plastically deformed to press the third binding jaw by press working.
In addition, the bottom plate has an exhaust hole formed in an edge portion thereof in a vertical direction.
The main plate bottom plate has a bottom plate extending portion disposed on the outer side of the binding edge and protruding downward so that a lower end of the bottom plate is disposed at a lower position than a lower surface of the bottom plate, And an exhaust groove formed concavely toward the upper direction may be provided.
The bottom plate of the main body bottom plate has a plurality of position fixing grooves formed concaved in an upward direction, and a plurality of position fixing grooves formed in the top surface of the bottom plate so as to conform to the position fixing grooves, A position fixing protrusion may be provided.
Since the present invention is realized by the direct heat transfer method in which heat transmitted from the heating means is directly transferred by contact until the heat is transferred to the cooking surface and the indirect heat transfer type double heat transfer method in which heat transfer is performed without mechanical contact, Is uniformly maintained as a whole, and a flat plate type heating means such as an induction range can be cooked under optimum temperature conditions.
In addition, the lower plate coupled to the main body bottom plate is further firmly coupled to prevent any disconnection, thereby providing a long service life.
