Description

인덕션 프라이팬 제조용 자성체 금속판재, 그 자성체 금속판재로 구성된 인덕션용 프라이팬 및 인덕션용 프라이팬 제조방법{Induction pans for manufacturing magnetic metal plate processing, consisting of ferromagnetic metal plate that ash pans for induction and induction pans for manufacturing method}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic metal plate for manufacturing an induction frying pan, an induction frying pan comprising the magnetic metal plate, and a manufacturing method for the induction pans for induction pans for induction pans for manufacturing magnetic metal plate processing,

본 발명은 인덕션 가열기구에서 프라이팬을 가열시 열보존율을 높이고 열에 의한 팽창으로 프라이팬의 바닥이 솟구치는 현상을 방지할 수 있도록 구성된 인덕션용 프라이팬에 관한 것으로서, 더욱 상세하게는 인덕션 프라이팬 제조용 자성체 금속판재, 그 자성체 금속판재로 구성된 인덕션용 프라이팬 및 인덕션용 프라이팬 제조방법에 관한 것이다.The present invention relates to an induction frying pan configured to increase heat retention when heating a frying pan in heating and prevent the bottom of the frying pan from rising due to heat expansion. More particularly, An induction frying pan composed of a magnetic metal plate, and a manufacturing method of a frying pan for induction.

주지하는 바와 같이 인덕션용 프라이팬은 인덕션 가열기구의 자기장에 의해 발생하는 유도전류를 열원으로 가열되게 하여 음식물을 조리를 할 수 있도록 구성되어 있다.As is known, the induction frying pan is constructed so that the induction current generated by the magnetic field of the induction heating mechanism is heated by the heat source to cook the food.

상기와 같은 인덕션용 프라이팬을 가열하는 인덕션 가열기구는 전자기유도 현상에 의해 금속에 소용돌이 전류가 발생하고 줄열에 의해 금속이 가열되어 순간적으로 강한 열을 낼 수 있도록 구성되어 있기 때문에 가열하기 위해서는 반드시 금속재 용기를 사용해야 하지만 금속재 프라이팬의 대부분은 매우 무거운 단점이 있다.Since the induction heating mechanism for heating the induction frying pan as described above generates a swirling current in the metal due to the electromagnetic induction phenomenon and the metal is heated by the heat of the strip to generate instantaneous strong heat, , But most of the metal frying pans have very heavy drawbacks.

그래서 무게가 가벼운 알루미늄 재질로 프라이팬 본체를 제조하고 프라이팬의 바닥 밑면에 자성체 금속판재를 결착시켜 구성된 인덕션용 프라이팬이 제조되고 있다.Thus, a frying pan for induction is manufactured by manufacturing a frying pan body with a lightweight aluminum material and binding a magnetic metal plate to the bottom surface of the frying pan.

종래 상기와 같이 알루미늄 재질로 구성된 프라이팬의 바닥 밑면에 자성체 금속판재를 결착시켜 제조된 인덕션용 프라이팬은 드로잉가공에 의해서 제조되는 데, 프레스 드로잉 금형 위에 프라이팬 바닥면 보다 지름이 작은 자성체 금속판재와 그 위에 알루미늄 판재를 올려놓고, 프레스의 가압력에 의해서 알루미늄 판재에 자성체 금속판재가 결착되면서 드로잉가공에 의한 성형으로 프라이팬 본체가 제조된다.An induction frying pan manufactured by binding a magnetic metal plate to the bottom surface of a frying pan made of aluminum as described above is manufactured by a drawing process. A magnetic metal plate having a diameter smaller than the bottom surface of the frying pan is formed on the press drawing die. The frying pan main body is manufactured by molding by drawing while the aluminum plate material is placed and the magnetic metal plate is bonded to the aluminum plate material by the pressing force of the press.

상기와 같이 제조된 프라이팬은 가볍기 때문에 사용시 편리함과 제조공정이 간단하여 대량생산을 할 수 있는 장점이 있으나, 프라이팬의 바닥면과 측면이 같은 두께로 제조될 수밖에 없기 때문에 바닥면이 얇아서 가열시 바닥면이 솟구쳐 변형되므로 유도전류가 골고루 발생하지 못하고, 또 열보존율이 떨어지는 관계로 음식물이 타거나 골고루 익지 않는 단점이 있다.Since the frying pan manufactured as described above is advantageous in that it can be mass-produced because it is simple in use and simple in use because of its lightness, the bottom surface and the side surface of the frying pan can be manufactured to have the same thickness. Therefore, The induction current can not be uniformly generated, and the heat retention rate is lowered, so that the food is burned and not uniformly ripened.

상기한 단점을 해결하기 위하여 다이케스팅 금형에 자성체 금속판재를 넣고 알루미늄 용액을 금형으로 주입하여 자성체 금속판재를 결합하여 구성된 인덕션용 프라이팬이 있다.To solve the above-mentioned disadvantages, there is an induction frying pan in which a magnetic metal plate is inserted into a die-casting mold and an aluminum solution is injected into a mold to combine magnetic metal plates.

상기와 같이 다이케스팅 금형에 의해서 제조된 프라이팬의 경우에 프라이팬의 바닥은 두껍게 하고 측면의 두께는 얇게 할 수 있어 사용시 열보존율이 양호하고 가벼운 장점은 있다.In the case of the frying pan manufactured by the die-casting mold as described above, the bottom of the frying pan can be made thicker and the thickness of the side face can be made thin, so that the heat retention ratio is good and light.

그러나, 고온의 알루미늄 용액을 취급하기 때문에 프라이팬 제조과정에 위험이 따르고 생산성도 크게 떨어질 뿐만 아니라, 다이케스팅시 사출압력에 의해서 기포가 형성되고, 불순물이 많이 포함되어 있기 때문에 프라이팬의 품질이 크게 떨어진다.However, since the hot aluminum solution is handled, the frying pan is in danger of being manufactured and the productivity is greatly reduced. In addition, the quality of the frying pan is greatly deteriorated because bubbles are formed by the injection pressure during die casting and a lot of impurities are contained.

또한, 자성체 금속판재가 결착된 바닥 밑면의 평탄도가 균일하지 못하여 프라이팬으로 사용시 인덕션 가열기구와 밀착면이 불안정하여 이를 해결하기 위해 자성체 금속판재의 표면을 가공함으로써, 자성체 금속판재의 두께가 일정하지 않아 바닥면의 국지적 온도차이가 크게 발생하여 음식물이 골고루 익혀지지 않고, 고온의 열에 의해서 자성체 금속판재가 뒤틀리는 현상이 생기게 되는 결과로 프라이팬의 수명이 단축되는 등 구조적으로 많은 문제가 있다.In addition, since the flatness of the bottom surface to which the magnetic metal plate is bonded is not uniform, the induction heating mechanism and the contact surface are unstable when used as a frying pan, and the surface of the magnetic metal plate is processed to solve this problem. The local temperature difference of the bottom surface is large and the food is not uniformly cooked and the magnetic metal plate is twisted due to the heat at high temperature. As a result, the lifespan of the frying pan is shortened.

본 발명은 상기한 문제점을 해결하기 위한 것으로서, 음식물을 조리하기 위하여 인덕션 가열기에서 프라이팬을 가열시 프라이팬의 바닥면이 솟구치지 않게 하고 열보존율을 높여 음식물이 타지 않고 골고루 익혀질 수 있도록 하는 동시에 프라이팬을 경량화시켜 사용시에 편의성을 크게 향상시킬 수 있게 구성된 인덕션용 프라이팬을 제공하는데 그 목적이 있다.DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a frying pan in which when the frying pan is heated in an induction heater for cooking food, the bottom surface of the frying pan is not raised, And it is an object of the present invention to provide an induction frying pan which is configured to be lightweight and greatly improve convenience in use.

상기 목적을 달성하기 위한 본 발명에 의한 인덕션 프라이팬 제조용 자성체 금속판재는, 관통공들이 형성되고 상기 관통공들의 가장자리를 절곡하여 상부로 돌출된 결합구를 갖는 관통공과, 하부로 돌출된 결합구를 갖는 관통공이 교대로 형성되어있다.According to an aspect of the present invention, there is provided a magnetic metal plate material for manufacturing an induction frying pan, comprising: a through hole having through holes formed therein and having a coupling hole protruded upward by bending an edge of the through holes; The balls are alternately formed.

상기와 같이 구성된 자성체 금속판재가 프라이팬 본체 성형용 알루미늄 판재와 밑판용 알루미늄 판재 사이에 결착되고, 상기 밑판용 알루미늄 판재의 하부에는 관통공의 가장자리를 절곡하여 상부로 돌출된 결합구를 갖는 관통공들이 형성된 자성체 금속판재가 압착되어 구성된 후, 드로잉 가공에 의해서 인덕션용 프라이팬이 성형된다.The magnetic metal plate material constituted as described above is bonded between the aluminum plate material for molding the frying pan body and the aluminum plate material for the bottom plate, and the through holes having the engaging holes protruding upward are formed in the lower part of the aluminum plate material After the magnetic metal plate is pressed and formed, the induction frying pan is formed by drawing processing.

상기와 같이 구성된 인덕션용 프라이팬의 제조방법은, 프레스 하부금형 위에 상부로 돌출된 결합구를 갖는 관통공들이 형성된 자성체 금속판재를 놓고, 그 위에 밑판용 알루미늄 판재와, 상,하부로 돌출된 결합구를 갖는 관통공들이 형성된 자성체 금속판재와, 프라이팬 본체 성형용 알루미늄 판재를 차례로 놓고 상부금형으로 가압하여 자성체 금속판재와 밑판용 알루미늄 판재와 자성체 금속판재가 일체로 형성된 프라이팬 본체 성형용 알루미늄 판재를 제조한 다음, 드로잉 가공으로 인덕션용 프라이팬을 성형하여 제조하는 것이다.The manufacturing method of the induction frying pan constructed as described above comprises the steps of placing a magnetic metal plate on which a through hole having a coupling hole protruding upwardly is formed on a press lower mold and placing an aluminum plate material for the base plate thereon, And an aluminum plate for forming a frying pan body were placed in order and pressed with an upper die to produce an aluminum plate for molding a frying pan body in which a magnetic metal plate, an aluminum plate for a base plate and a magnetic metal plate were integrally formed , And a drawing machine for molding an induction frying pan.

본 발명에 의한 인덕션용 프라이팬의 또다른 제조방법은, 드로잉 금형 위에 상부로 돌출된 결합구를 갖는 관통공들이 형성된 자성체 금속판재를 놓고, 그 위에 밑판용 알루미늄 판재와, 상,하부로 돌출된 결합구를 갖는 관통공들이 형성된 자성체 금속판재와, 프라이팬 본체 성형용 알루미늄 판재를 차례로 놓고 드로잉 금형으로 가압하여 인덕션용 프라이팬을 성형하여 제조하는 것이다.Another method of manufacturing an induction frying pan according to the present invention is a method for manufacturing a frying pan for induction, comprising the steps of: placing a magnetic metal plate on which a through hole having a coupling hole protruding upwardly is formed on a drawing die; A magnetic metal plate on which the through holes having spheres are formed, and an aluminum plate for forming the frying pan main body, in this order, and pressing them with a drawing die to mold the induction frying pan.

이상과 같은 본 발명에 의하면, 인덕션 가열기에 의해서 가열된 프라이팬의 바닥이 열팽창할 때 알루미늄 판재 사이에 금속판재가 개재되어 변형을 상쇄시키기 때문에 바닥면이 솟구치는 것과 자성체 금속판재가 뒤틀리는 것을 방지하여 프라이팬을 오랜기간 사용할 수 있는 효과가 있다.According to the present invention, when the bottom of the frying pan heated by the induction heater is thermally expanded, a metal plate is interposed between the aluminum plates to cancel the deformation, thereby preventing the bottom surface from rising and the magnetic metal plate from being twisted, There is an effect that can be used.

그리고, 프라이팬의 바닥면은 적층되어 두껍고 측면은 얇은 형태로 구성되어 있기 때문에 음식물이 타지 않고 골고루 익힐 수 있고, 프라이팬의 경량화로 사용시 편리함을 제공할 수 있는 효과가 있다.Since the bottom surface of the frying pan is laminated to be thick and the side surface is thin, the frying pan can be cooked evenly without burning the food, and the frying pan can be made lightweight.

또한, 프라이팬의 바닥 밑면에 자성체 금속판재가 프레스 가압력에 의해서 결착되었기 때문에 별도로 가공하지 않아도 바닥면이 평탄하게 형성됨으로써 인덕션 가열기구와 밀착면이 일정하게 유지되어 바닥면에 균일한 온도로 음식물을 골고루 익혀주는 효과가 있다.In addition, since the magnetic metal plate is bonded to the bottom surface of the frying pan by press-pressing force, the bottom surface is formed flat without any additional processing, so that the induction heating mechanism and the adhered surface are kept constant, It is effective.

먼저, 본 발명을 구성하는 자성체 금속판재(1)는 관통공(2)(3)들이 상부로 돌출된 결합구(2')와 하부로 돌출된 결합구(3')를 가지고 있기 때문에 프라이팬 본체 성형용 알루미늄 판재(10)와 밑판용 알루미늄 판재(20) 사이에 결착되어 서로 분리되지 않게 하는 동시에 조리시 인덕션 가열기의 열에 의해서 팽창될 때 상호 변형을 상쇄시키는 작용을 하게 되므로 프라이팬의 바닥면이 솟구치는 것과 자성체 금속판재가 뒤틀리는 것을 방지할 수 있게 된다.First, since the magnetic metal plate 1 constituting the present invention has the coupling hole 2 'and the coupling hole 3' projecting upward from the through holes 2 and 3 and the coupling hole 3 ' So that they are prevented from being separated from each other, and at the same time, when they are expanded by the heat of the induction heater at the time of cooking, they act to cancel mutual deformation, so that the bottom surface of the frying pan rises And the magnetic metal plate member can be prevented from being warped.

자성체 금속판재(1)에 상부로 돌출된 결합구(2')를 갖는 관통공(2)이 프라이팬 본체 성형용 알루미늄 판재(10)의 밑면에 형성된 홈(12)과 돌출부(11)에 결합되고 하부로 돌출된 결합구(3')를 갖는 관통공(3)은 밑판용 알루미늄 판재(20)에 형성된 홈(24)과 돌출부(23)에 결합되며, 또 자성체 금속판재(5)의 상부로 돌출된 결합구(6')를 갖는 관통공(6)이 밑판용 알루미늄 판재(20)의 하부에 형성된 홈(22)과 돌출부(21)에 결합되면서 압착되어 있기 때문에 견고한 결합상태를 유지할 수 있게 된다.A through hole 2 having a coupling hole 2 'protruded upward from the magnetic metal plate 1 is coupled to the groove 12 and the protrusion 11 formed on the bottom surface of the aluminum plate 10 for forming the frying pan body The through hole 3 having the coupling hole 3 'protruding downward is coupled to the groove 24 and the protrusion 23 formed in the aluminum plate 20 for the base plate and is connected to the upper portion of the magnetic metal plate 5 Since the through hole 6 having the protruding engagement hole 6 'is pressed and joined to the groove 22 and the protrusion 21 formed at the lower part of the aluminum plate 20 for the bottom plate, do.

그리고, 프라이팬(30)의 바닥(31)이 자성체 금속판재(5)와 밑판용 알루미늄 판재(20)와 자성체 금속판재(1)로 적층되어 두껍기 때문에 조리시에 열보존율을 크게 향상시키는 작용을 하게 되므로 음식물이 타지 않고 골고루 익혀서 조리할 수 있다.Since the bottom 31 of the frying pan 30 is laminated with the magnetic metal plate 5, the aluminum plate 20 for the base plate and the magnetic metal plate 1, So that the food can be cooked evenly without burning.

특히, 프라이팬(30)의 바닥 밑면에 자성체 금속판재(1)(5) 및 밑판용 알루미늄 판재(20)가 프레스 금형의 가압력에 의해서 결착되었기 때문에 자성체 금속판재(1) 및 밑판용 알루미늄 판재(20)은 물론이고, 프라이팬(30)의 바닥 밑면을 이루는 자성체 금속판재(5)의 평탄도가 양호하게 제공된다.Particularly, since the magnetic metal plate members 1 and 5 and the aluminum plate member 20 for the base plate are bonded to the bottom surface of the frying pan 30 by the pressing force of the press die, the magnetic metal plate member 1 and the aluminum plate member 20 And the flatness of the magnetic metal plate 5 constituting the bottom surface of the frying pan 30 is favorably provided.

따라서, 후가공으로 바닥과 자성체 금속판재를 평탄하게 가공하지 않아도 자성체 금속판재(5)의 두께가 일정하게 유지되는 결과로 프라이팬을 인덕션 가열기에 올려놓고 사용시 접촉면적이 균일하고 일정하게 유지됨으로써, 유도전류가 골고루 발생하여 빠른 가열이 가능하여 열손실을 줄이면서 조리가 가능하게 된다.Therefore, even if the bottom and the magnetic metal plate are not processed in a post-process, the thickness of the magnetic metal plate 5 is kept constant. As a result, the frying pan is placed on the induction heater and the contact area is kept uniform and constant during use. So that rapid heating is possible and cooking can be performed while reducing heat loss.

또한, 프라이팬(30)의 조직이 다이케스팅에 비하여 조밀하여 가열에 의해서 바닥이 솟구치는 변형이 방지되고, 밑판용 알루미늄 판재(20) 및 자성체 금속판재(1)(5)이 프레스 가압력에 의해서 견고하게 결착되고 절삭가공을 하지 않았기 때문에 두꺼운 두께 유지로 인하여 프라이팬(30)이 변형되는 것과 밑판용 알루미늄 판재(20) 및 자성체 금속판재(1)(5)가 분리되는 것을 방지하여 프라이팬의 품질을 향상시키는 작용을 하게 된다.In addition, the structure of the frying pan 30 is dense compared to the die casting, and deformation of the floor caused by heating is prevented, and the aluminum plate material 20 and the magnetic metal plates 1, 5 are firmly fastened The frying pan 30 is deformed owing to the maintenance of the thick thickness and the separation of the aluminum plate material 20 and the magnetic metal plate materials 1 and 5 is prevented so as to improve the quality of the frying pan .
