Abstract

The present invention relates to a method for manufacturing a hot plate of a cooking pan, which is used by double bonding to a lower surface of a frying pan or a pressure cooker. When heated, heat conduction is directly conducted from the heating part to the other surrounding part so that the temperature of the cooking utensil is raised so that the entire lower surface of the cooking utensil cannot be uniformly raised and any particular part always maintains high temperature. Therefore, the cooking material is pressed or burned in the hot portion and immature in the peripheral portion.

Accordingly, the present invention eliminates the disadvantages of such existing products and in the configuration of the larger heating area to gradually increase the overall temperature to a uniform and efficient temperature distribution in the center of the hot plate 60 protrudes a circular protrusion 63 in the center thereof The inner space of the hot plate 60 which protrudes a plurality of smaller circular protrusions 65 along the periphery and forms a structure to be joined to the lower surface 77 of the cooking utensil in a raised form along the periphery of the hot plate 60. Refractory powder and metal beads (73) are mixed at an appropriate ratio so that balanced thermal conductivity is well controlled and compressed and filled in the lower portion of the center portion 75 of the frying pan 3 or the pressure cooker 5 and the lower portion of the peripheral portion. The refractory body 70 is formed by double bonding so that the 77 and the hot plate 60 are integrally formed. In the high temperature portion which is directly heated from the heat source 80, conduction of heat is appropriate. The heat is gradually transferred to the part far away from the heat source 80 so that the temperature gradually rises as a result of uniform and efficient temperature distribution, so that the part that is overheated and is not pressed or burned is also generated. It will not be.

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. Cooking frying pan (3) shown in Examples 3 and A in a state in which the refractory powder and the metal beads (73) in the inner space of the hot plate (60) are mixed and compressed in an appropriate ratio so that balanced thermal conductivity is well controlled. In addition, the base temperature of the hot plate 60 in the double bond so that the central portion lower surface 75 and the peripheral portion lower surface 77 and the hot plate 60 of the pressure cooker 5 illustrated in FIGS. To raise the temperature to 200 ℃ above the boiling point of water (100 ℃) to control the conduction of heat. Is a structure characterized in that the refractory body 70 is formed by closely melting and bonding at a high frequency in a state in which even a small amount of air remaining in the compressed-filled refractory powder 70 is thermally expanded and released to the outside. The following describes the effect.

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 where the large and small circular protrusions 63 and 65 are directly bonded to each other due to the direct connection of each other are quickly and directly conducted as indicated by the arrows, and the refractory powder and the metal beads ( Since heat is transferred from a plurality of smaller circular protrusions 65 through the compression-filled refractory body 70 in which 73) is mixed, 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. By conducting heat conduction through the compression-filled refractory body 70 in which the refractory powder and the metal beads 73 are mixed around the heat conduction, the heat conduction is controlled. In the distant part, in order to allow a large amount of heat to be conducted quickly, the circular protrusion 63 protruding from the center of the hot plate 60 and the periphery may be joined to the lower surfaces 75 and 77 of the cooking utensil. The structure is formed so that it can be bonded directly without any intermediate heat conduction media to achieve efficient heat conduction. Efficient distribution of temperature will be the temperature rises.

Therefore, it is possible to control the conduction of heat according to the large and small and the number of the circular protrusions (63), 65 or the number of compression-filled refractory powder thickness and the mixing ratio of the metal beads (73). 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 refractory body 70 and the metal ball 73, the cooling source does not cool quickly and maintains a proper 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 food is not overheated during cooking. It is a new way of making hotplates for a cookware.
