The hot plate is melted with a high-frequency wave to control the temperature so that a lower surface(75) of the center portion and lower surface(77) of the peripheral portion of a conventional frying fan or kettle correspond to the center portion and peripheral portion of the hot plate.

Description

{The Method of Making the Hot Plate of Fry Pan for food.}

The present invention relates to a hot plate manufacturing method of a cooking fry pan, which is used by double bonding to a lower surface of a cooking fry pan or a pressure cooker, and is provided from a heat source in most cooking appliances such as a frying pan or a pressure cooker. If you observe the bottom part being heated, if you heat concentrated part of the bottom part of the bottom part, the heat conducts to the surrounding part at high speed and the temperature rises, so the high part and the low part coexist in the whole lower area. The cooking material is pressed or burned and other surrounding parts are in a state in which the cooking material is immature due to the slow conduction of heat. therefore,

In the present invention, it is an object of the present invention to remove this drawback and allow the temperature to be gradually raised to a uniform and efficient temperature distribution with a larger heating area.

According to the present invention, as described above, most of the cooking utensils using the conventional hot plate are heat-converted at a high speed when the lower portion of the cooking utensils is heated so that the temperature of the cooking utensils is increased, so that the temperature distribution of the entire lower area is distributed. From the beginning of heating, high temperature and low part coexist in the whole area from the beginning of heating, so the cooking material is pressed or burned in the high temperature part, and the cooking material is immature due to the late conduction of heat in other parts. It can be seen that it is in a state. Therefore, the present invention eliminates these defects, so that even in a wider heating area, the temperature is gradually raised over the entire heating area with a uniform and efficient temperature distribution, so that no part is pressed or burned, and no immature part occurs. There is a technical problem in providing a new hot plate manufacturing method of a cooking utensil capable of cooking.

The configuration of the present invention relates to a method for manufacturing a hot plate for further improving the function of utility model registration No. 3005076 (Functional Frying Pan), which has been previously registered and pre-registered, and has a cooking pan (3) for cooking from a heat source (80). Or the lower surface of the cooking appliance at a high frequency with a hot plate 60, characterized in that the temperature is gradually raised over the entire heating area with a uniform and efficient temperature distribution at the bottom of the directly heated portion of the pressure cooker (5). As a dual structure formed by melt bonding so as to be integral with 75) and (77), detailed descriptions as shown in Figs. 3A, 4 and 4 are as follows.

The hot plate 60 of the present invention protrudes a circular protrusion 63 in the center of the hot plate 60 as illustrated in FIG. 4 in shaping a casting made of aluminum (AL), copper (CU), cast iron, or the like. And protrude a plurality of smaller circular protrusions 65 along the periphery thereof and form a structure to be joined to the lower surfaces 75 and 77 of the cooking utensil in a raised form along the periphery of the hot plate 60. Refractory powder 70 and metallic bead-shaped particles 73 in the inner space of the hot plate 60 are mixed and compressed at a proper ratio so that balanced thermal conductivity is well controlled. In the combination of the cooking pan (3) or the lower portion of the center portion 75 and the peripheral portion lower surface 77 and the hot plate 60 of the pressure cooker 5 illustrated in Figures 3 and B, so as to be integral The base temperature of the hot plate 60 is raised to about 200 ° C higher than the boiling point of water (100 ° C) to Its structure is characterized by melt-bonding closely at high frequency in a state in which even a small amount of air remaining in the compressed-filled refractory powder 70 to control the degree is thermally expanded and released to the outside. Is as follows.

Looking at the conduction process of heat from the hot plate 60 to the bottom of the cooking pan or pressure cooker as shown in FIG. The portions 75 and 77, to which the large and small circular protrusions 63 and 65 are directly bonded to each other due to the direct connection, are quickly and directly conducted as indicated by arrows of heat, and the powder of the refractory material 70 Since heat is transferred from the smaller number of circular protrusions 65 through the compression-filled object in which the particles 73 of the metallic beads form are mixed, the conduction of heat is controlled. Therefore, in the high temperature portion where the heat is directly heated from the heat source 80, a plurality of smaller and lower protruding circular projections 65 than the central circular projections 63 in order to properly control the heat conduction so that the cooking material is not pressed or burned. The conduction of heat is controlled by the conduction of heat through the compression-filled object in which the powder of refractory material 70 and the metallic bead-shaped particles 73 are mixed around it, and the conduction of heat is also controlled from the heat source 80. And the lower surface 75, 77 of the cooking utensil in the form of a protruding portion of the circular protrusion 63 protruding from the central portion of the hot plate 60 and the periphery portion so as to quickly conduct a large amount of heat to the far part of the periphery. The structure is formed so that it can be bonded directly so that there is no middle heat conduction medium, so that the heat conduction is made more efficient. In a uniform and effective temperature distribution it will be the temperature rises.

Therefore, the conduction of heat can be controlled according to the large and small and the number of the circular protrusions 63 and 65 or the mixing ratio of the powder 70 of the refractory material filled with compression and the particle size 73 with the metallic beads. . Therefore, the food is partly overheated during cooking, so as not to be pressed or burned, so that the immature part does not occur.

In addition, in the state in which the heat source 80 is stopped, due to the amount of heat stored in the powder 70 of the refractory material and the particles 73 in the form of metallic beads, it does not cool quickly and maintains an appropriate temperature for a predetermined time.

As described above, heat is transferred by a method of delaying the conduction of heat to a portion far from the hot plate 60, which is a main part of the present invention, so that a large amount of heat is quickly conducted and directly conducting heat. By controlling the temperature, the temperature rises gradually with a uniform and efficient temperature distribution, so that the part is not overheated during cooking. It's a new hotplate manufacturing method for a cookware.
