Abstract

The present invention relates to a food cooking vessel in which a continuous radiator, having heat absorbing holes in multiple sizes, is embedded. According to the present invention, a plurality of heat absorbing holes having different shapes and sizes are formed in the continuous radiator embedded in the bottom of the main body made of metal. Therefore, fast cooking is possible according to the high thermal conductivity of the metal, and the heat storage function of the continuous radiator allows the heat dissipation to be maintained even after heating, thereby providing an effect of maintaining the high temperature. In particular, as the heat absorbing hole formed in the center of the continuous radiator is the largest, the area where the metal bottom of the cooking vessel is in contact with the continuous radiator is increased, thereby quickly transferring heat to the continuous radiator in a short time.

Description

Food cooking container with a continuous radiator having a plurality of endothermic holes {Cookware having radiating materials}

The present invention relates to a food cooking container, and more particularly, to a technology in which a sustained heat radiator is built into the main body of the container, so that a high temperature maintaining effect can be seen for a predetermined time after cooking.

Metal food cooking containers, such as pots and pressure cookers, can transfer heat quickly, allowing for quick cooking, and some containers can also be used in an induction range. However, due to the nature of the material can not keep the heat for a long time, when the heating is finished boiling immediately and the cooked food cools quickly.

On the other hand, the casserole made from raw materials such as kaolin or loess has high heat storage performance, so that heat can be released for a certain time even after finishing cooking to maintain a high temperature. However, due to its low thermal conductivity, it does not boil as quickly as a pot and cannot be used in an induction range.

As described above, the cooking vessels have distinct advantages and disadvantages according to material characteristics, and a functional cooking vessel capable of utilizing all the advantages of each cooking vessel is required.

Korean Patent Application Publication No. 10-2015-0111180 (2015.10.05. 'Induction heating dedicated ceramic container for thermal shock alleviation', hereinafter referred to as 'prior art') forms an induction heating sensitive member made of metal around the ceramic body. A functional container is disclosed which can be used in an induction range.

However, in the prior art, the entire container is made of ceramic, so the thermal conductivity is low, and thus, there is a disadvantage in that fast cooking is impossible as in the existing casserole. Furthermore, since the ceramic container and the induction heating sensitive member are simply joined, there is a concern that the joining site may be separated due to the difference in the degree of thermal expansion.

The present invention has been made to solve the problems of the prior art as described above, the continuous heat sink is built in the bottom of the metal body, it is possible to quickly cook according to the high thermal conductivity of the metal heat storage function It is an object of the present invention to provide a food cooking container capable of keeping food at a high temperature for a predetermined time due to continuous emission of radiant heat even after heating.

In addition, by placing the continuous radiator having a plurality of through holes in the space inside the mold, by injecting a metal melt to produce a centrifugal casting method, the melt is solidified in a state filled around the continuous radiator and the through hole, Another object is to provide a food cooking container in which the metal body grasps the continuous radiator so as to completely eliminate the fear of departure due to the difference in coefficient of thermal expansion.

Food cooking container according to the present invention for achieving the above object, the main body having a food cooking space; And a continuous radiator provided inside the bottom surface of the main body.

Here, the continuous radiator may be made of a ceramic material.

In addition, the continuous radiator may be formed with a plurality of through holes penetrating both sides.

In addition, the main body may be manufactured by centrifugal casting a melt of a metal material.

According to the present invention has the following effects.

First, the heat radiating element is located on the bottom of the inner body of the metal material is excellent in maintaining the high temperature of the cooked food. That is, the ceramic heat radiator has a high heat storage performance, so that it can absorb heat during the cooking process, and when the cooking is finished, it releases the heat it contains as radiant heat, thereby preventing the cooked food from being quickly cooled. That is, the effect of maintaining the high temperature such as the earthenware will be seen.

Of course, the existing casserole has a low thermal conductivity is not possible fast cooking of food, there was a problem that can not be used in the induction range. However, the food cooking container according to the present invention basically has a high thermal conductivity because the body is made of a metal material. In particular, even in the food cooking container, even if the heat sink is located inside the bottom of the main body, the metal part around the heat sink and the side of the body forms a heat transfer path, and heat can be transferred through the plurality of through holes formed in the heat sink. Fast cooking is possible. In addition, the metal body allows for use in the induction range.

In addition, the heat-radiating body embedded in the food cooking container according to the present invention is formed in the heat absorbing hole is different in shape and size. In particular, the size of the heat absorbing hole formed in the center is formed to be the largest to increase the area of contact with the metal bottom body and the continuous radiator of the cooking vessel, it is possible to quickly transfer heat to the heat transfer body in a short time. Therefore, even if the cooking vessel is heated only for a short time, it is advantageous to maintain the heat can be heated to a high temperature in a continuous radiator instantaneously.

In addition, the food cooking container according to the present invention is manufactured by the centrifugal casting method, the density of the melt is increased by the centrifugal force to remove microbubbles and the structure is dense, which greatly improves durability. Therefore, it is possible to solve the problem that a gap occurs or a detergent or food penetrates into a fine hole. That is, if there are micro-bubbles or cracks, the durability may be rapidly weakened, such as expansion when a high heat is received, causing cracks. In the present invention, this can be solved by completely removing the bubbles through centrifugal casting of the metal melt.

In addition, the through-hole formed in the continuous radiator facilitates the flow of the melt when injecting the melt into the casting space, so that the melt can be densely injected without bubble formation on both sides of the continuous radiator. Accordingly, when the solidified in the state in which the melt is injected into both the periphery of the radiator and the through-hole, the metal body is formed to hold firmly through the periphery of the radiator and through the through-hole, the degree of thermal expansion of the dissimilar materials is different. Even if the departure does not occur.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described. However, some components irrelevant to the gist of the present invention will be omitted or compressed, but the omitted elements are not necessarily required in the present invention, and may be combined and used by those skilled in the art. Can be.

1 is a view for explaining various forms of a food cooking container according to an embodiment of the present invention. That is, the food cooking container to be dealt with in the present invention may be manufactured in various forms such as a pot, a casserole and a pressure cooker. Hereinafter, the food cooking container 10 in a pot form will be described as an example.

Referring first to FIG. 6, the food cooking container 10 according to the embodiment of the present invention includes a main body 11 having a food cooking space and a continuous heat radiator 12 provided inside the bottom surface of the main body 11. do. Hereinafter, the method of manufacturing the food cooking container 10 will be described first with reference to FIGS. 2 and 3, and then the characteristics of the food cooking container 10 manufactured will be described.

As shown in FIG. 3A, a mold is prepared to manufacture the food cooking container 10. The mold includes a lower mold 21 and an upper mold 22. When the upper mold 22 is in close contact with the lower mold 21, the mold corresponds to the shape of the food cooking container 10, that is, the shape of the main body 11. The space 24 is formed. In this case, before the upper mold 22 and the lower mold 21 are in close contact with each other, the continuous radiator 12 is first positioned on the lower mold 21.

The continuous radiator 12 should be located inside the bottom surface of the main body 11 in the final product state of the food cooking container 10. Therefore, the continuous radiator 12 should not be directly mounted on the lower mold 21, but should be installed in the state of floating in the casting space 24 inside the mold by the supporting means 31.

When the heat dissipation element 12 is set on the supporting means 31 in the casting space 24 inside the mold, the main body is formed through the injection hole 23 of the upper mold 22 as shown in FIG. The melt 32, which is a raw material of (11), is injected <S210>. The melt 32, which is a metal raw material, may be an alloy material such as AC4C.

The melt 32 fills the casting space 24, and additionally injects a sufficient amount to the inlet 23. When the density of the melt 32 is increased during centrifugal casting, the volume may be reduced, and thus an empty space may be formed in the casting space 24. For this purpose, the melt 32 of the extra portion is injected.

On the other hand, the support means 31 supporting the continuous radiator 12 may be a thin metal plate or the like, preferably, the support means 31 may be made of the same material as the melt 32. The supporting means 31 is melted by the high temperature of the melt 32 after the melt 32 is injected into the casting space 24 to be integrated with the melt 32. Of course, when the support means 31 melt, the continuous radiator 12 may fall, but the support means 31 may hold until the melt 32 at the bottom of the continuous radiator 12 is solidified to some extent. Therefore, even though the support means 31 melt, the yongwoong which has started to solidify somewhat under the continuous radiator 12 supports the continuous radiator 12.

Referring to the perspective view of the continuous radiator 12 shown in FIG. 5, a plurality of through holes 13 penetrating both surfaces are formed in the ceramic continuous radiator 12. Therefore, when the melt 32 is injected in a state in which the continuous heat radiator 12 is separated from the lower mold 21 by the support means 31, the melt 32 passes through the through hole 13 and the continuous heat radiator 12. (12) It can be densely injected to both sides. If there is no through hole 13, the melt 32 has to flow downward through the circumference of the radiator 12, in which case the bubbles are not discharged smoothly and the bubbles are trapped around the radiator 12.

On the other hand, the continuous radiator 12 may be used a variety of ceramic materials, such as minerals such as kaolin, loess, zirconium, alumina. Of course, in addition to these examples, various known ceramic materials may be used.

Even if the melt 32 is injected into the casting space 24 inside the mold and immediately cooled, the food cooking container 10 provided with the continuous radiator 12 inside the main body 11 may be produced. However, when the food cooking container 10 is manufactured by the general casting method, the main body 11 is likely to be solidified by solidifying with the bubbles 32 formed in the melt 32.

The presence of microbubbles in the main body 11 means that the tissue is not dense, and the durability is also weak, which is likely to crack. In addition, the detergent may penetrate into cracks or micropores, and the detergent may leak out when cooking.

To this end, the present invention applies a centrifugal casting <S215> method. That is, the rotating means 40 is linked to the lower mold 21. Therefore, when the melt 32 is filled in the casting space 24 inside the mold, and the rotary means 40 is operated to rotate the entire mold as shown in FIG. 3 (c), a strong centrifugal force is applied to the melt 32. The density rises. That is, the microbubbles are removed and the structure of the melt 32 becomes dense.

Of course, according to the rotational movement of the mold, the heat radiator 12 may be shifted to one side out of the position. However, since the continuous radiator 12 only needs to be positioned inside the bottom of the food cooking container 10, there is no problem even if it is slightly biased to one side.

When the density of the melt 32 is increased through centrifugal casting and the structure becomes dense, the product is solidified by solidifying the melt 32 through the cooling process <S220> and then removing the mold as shown in FIG. Withdraw <S225>.

The product immediately withdrawn from the mold is shown in FIG. Since the melt 32 has been sufficiently injected to the injection hole 23 in the foregoing process, a protrusion corresponding to the shape of the injection hole 23 protrudes from the bottom surface of the food cooking container 10. Therefore, the food cooking container 10 as shown in the perspective view of FIG. 1 and the cross-sectional view of FIG. 6 is completed by removing the protrusions and subjecting to a post-processing <S230> such as flattening the inside of the solidified body 11.

Food cooking container 10 according to the present invention may be applied to a pot, pot, pot, etc., Figure 6 is an example of the pot is shown, Figure 7 (a) and (b) is an example of the pot and pressure cooker respectively Is shown.

The food cooking container 10 according to the present invention described above has the following characteristics.

First, since the continuous radiator 12 is located on the inner bottom of the main body 11 made of metal, the effect of maintaining the high temperature of the cooked food is excellent. That is, the continuous heat radiator 12 made of ceramic material has high heat storage performance and thus can absorb heat during the cooking process, and when cooking is finished, it releases the heat held therein as radiant heat to prevent the cooked food from being cooled quickly. That is, the effect of maintaining the high temperature such as the earthenware will be seen.

Of course, the existing casserole has a low thermal conductivity is not possible fast cooking of food, there was a problem that can not be used in the induction range. However, the food cooking container 10 according to the present invention basically has a high thermal conductivity because the body 11 is made of a metal material. In particular, even in the food cooking container 10, even if the continuous radiator 12 is located inside the bottom of the main body 11, as shown in FIG. 6, the metal part around the continuous radiator 12 and the side of the main body 11 is formed. The heat transfer path is formed, and heat can be transferred through the plurality of through holes 13 formed in the continuous radiator 12, thereby enabling fast cooking. In addition, it is also possible to use in the induction range through the metal body 11.

In addition, the food cooking container 10 according to the present invention is manufactured by a centrifugal casting method, the density of the melt 32 is increased by the centrifugal force to remove microbubbles, and the structure is dense, thereby greatly improving durability. Therefore, it is possible to solve the problem that a gap occurs or a detergent or food penetrates into a fine hole. That is, if there are micro-bubbles or cracks, the durability may be rapidly weakened, such as expansion when a high heat is received, causing cracks. In the present invention, this can be solved by completely removing the bubbles through centrifugal casting of the metal melt.

In addition, the through hole 13 formed in the continuous radiator 12 smoothes the flow of the melt 32 when injecting the melt 32 into the casting space 24 to form bubbles on both sides of the continuous radiator 12. The melt 32 can be injected densely without. Accordingly, when the melt 32 is solidified in both the periphery of the radiator 12 and the through hole 13, the metal body 11 is formed around the radiator 12 and the through hole 13. Since it becomes a form holding firmly through, even if the degree of thermal expansion of the dissimilar material is different, the departure phenomenon does not occur.

Meanwhile, in the above description and drawings, the through-hole 13 is formed and formed in the continuous radiator 12. However, even in the case of the continuous radiator 12 without the through-hole 13, the heat contained therein is released as radiant heat. It is also possible to maintain a high temperature, and to transfer heat quickly through the metal part around the radiator 12.

Preferred embodiments of the present invention described above are disclosed for the purpose of illustration, and those skilled in the art will be able to make various modifications, changes and additions within the spirit and scope of the present invention. And additions should be considered to be within the scope of the claims of the present invention.
