본 발명은 인덕션 렌지용 주방용기의 제조방법에 관한 것으로, 좀 더 상세하게는 비자성체인 주방용기 몸체에 자성강판의 결합이 다이캐스팅 공법을 통해 이루어지도록 하여 보다 저렴하고 대량생산이 가능하도록 한 인덕션 렌지용 주방용기의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a kitchen container for an induction stove, and more particularly, an induction stove that allows a combination of a magnetic steel plate to a non-magnetic kitchen container body through a die casting method to enable cheaper and mass production. It relates to a method of manufacturing a kitchen vessel.

일반적으로 가정이나 음식점에서 널리 쓰이고 있는 냄비류, 후라이팬, 솥 등의 조리용기들은 그 기능상 내열성 및 내구성을 요구하는 스테인레스나 알루미늄과 같은 비철금속 또는 세라믹을 재질로 성형되며, 이러한 조리용기의 바닥면에는 음식물이 눌어붙지 않도록 함과 아울러 깨끗하게 세척할 수 있도록 표면코팅처리하여 사용하고 있다.In general, cooking vessels such as pots, pans, and pots, which are widely used in homes and restaurants, are formed of non-ferrous metals or ceramics such as stainless steel or aluminum, which require heat resistance and durability in their functions. The surface coating is used to prevent this from sticking and to clean it.

한편, 최근에는 가스 레인지 대신에 인덕션 렌지의 사용이 급증하고 있으며, 이러한 인덕션 렌지는 전원을 공급받아 고전압이 인가되어 자장을 발생하기 위한 코일이 내장되어 있으며, 이와 같이 코일에 고전압이 인가되면 자장이 유도됨에 따라 이 자장이 ㅍ 미치는 영역에 있는 자성체가 가열되는 원리를 이용한 것이다.On the other hand, in recent years, the use of induction stoves instead of gas ranges are rapidly increasing, and these induction stoves are supplied with a high voltage and are supplied with a coil for generating a magnetic field. As it is induced, it uses the principle that the magnetic material in the region of the magnetic field is heated.

따라서, 가스 레인지용 주방용기는 발청방지를 위하여 비자성체인 알루미늄이나 스테인레스 스틸을 사용하는 반면에, 인덕션 렌지용 주방용기는 최소한 인덕션 렌지의 그릴에 닿는 부분, 즉 밑바닥에 자성을 갖는 철(Fe) 성분을 함유하고 있어야 한다.Therefore, while a gas range kitchen container uses aluminum or stainless steel, which is non-magnetic, in order to prevent corrosion, an induction stove kitchen container has at least a portion of the induction stove that touches the grill, that is, magnetic iron (Fe) at the bottom. Contains ingredients

대한민국 특허 출원번호 제2002-52401호에서는 인덕션 렌지용 후라이팬을 소개한 바 있으며, 이를 참고로 하여 종래 인덕션 렌지용 주방용기를 살펴보면 다음과 같다. In the Republic of Korea Patent Application No. 2002-52401 has introduced a frying pan for induction stove, the conventional induction stove kitchen container with reference to this as follows.

도 1은 종래 인덕션 렌지용 후라이팬을 나타낸 사시도이고, 도 2의 바닥면을 절단하여 나타낸 단면도이다.1 is a perspective view showing a conventional induction stove fry pan, a cross-sectional view showing the bottom surface of FIG.

이에 도시된 바와 같이, 종래 인덕션 렌지용 후라이팬은 알루미늄이 도금된 강판을 프레스 성형하여 제작한 음식물 삽입부(100)와, 상기 음식물 삽입부(100) 일측에 구비된 손잡이부(200)로 구성되고, 상기 음식물 삽입부(100)의 저면에는 알루미늄제의 보강판(300)이 부착되고, 상기 보강판(300)의 하부에는 알루미늄 도금강판제의 바닥가열부(400)가 적층되어 있다. 또한, 상기 음식물 삽입부(200)와 보강판(300) 사이 및 보강판(300)과 바닥가열부(400) 사이에는 자성체 성분의 파우더가 첨가된 접착제(500)가 도포되어 고주파열융착에 의해 각 층간의 결합이 이루어 지도록 되어 있다. As shown in the drawing, a conventional induction stove fry pan is composed of a food insert 100 prepared by press molding an aluminum plated steel plate, and a handle part 200 provided on one side of the food insert 100. The aluminum reinforcing plate 300 is attached to the bottom surface of the food inserting part 100, and the bottom heating part 400 made of aluminum plated steel is stacked below the reinforcing plate 300. In addition, between the food insert 200 and the reinforcing plate 300, and between the reinforcing plate 300 and the bottom heating unit 400 is applied an adhesive 500 to which the powder of the magnetic component is added and by high frequency heat fusion The coupling between layers is made.

이와 같이 종래 인덕션 렌지용 주방용기는 그 바닥부분의 각 층간의 결합이 용접공법에 의하여 제조된 것이 대부분이었으며, 이러한 용접방식은 작업공정의 자동화가 힘들어 다량생산이 어렵고, 노후시 층간 결합력의 약화로 내구성에 영향을 주는 문제점이 있었다. As such, most of the conventional induction stove kitchen containers are manufactured by the welding method in which the floors are bonded to each floor. This welding method is difficult to automate a large amount of production process due to the difficulty of automating the work process, and the weakening of the inter-layer bonding force during aging. There was a problem affecting durability.

이와 같은 문제점을 해결하기 위하여 바닥부분의 층간결합이 간편하고 이에 대량생산이 가능한 다이캐스팅공법을 이용한 인덕션용 주방용기의 제조가 부분적으로 이루어지고 있으나, 아직까지는 그 개발성과가 미비한 실정이다.In order to solve such a problem, the manufacturing of the induction kitchen container using the die casting method that can be easily mass-produced and coupled to the bottom part is made partially, but the development results are still inadequate.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 비자성체인 주방용기 몸체에 자성강판의 결합이 다이캐스팅공법을 통해 이루어지도록 하여 보다 저렴하고 대량생산이 가능하도록 한 인덕션 렌지용 주방용기의 제조방법을 제공하는 것을 목적으로 한다.Therefore, the present invention is to solve the above problems, a method of manufacturing a kitchen container for induction stove to enable a more inexpensive and mass production by combining the magnetic steel plate with the non-magnetic kitchen container body through the die casting method. The purpose is to provide.

상기와 같은 목적을 달성하기 위하여 본 발명은,The present invention to achieve the above object,

저면에는 내부로 절곡된 삽입부가 구비됨과 동시에 상기 삽입부 중앙에는 소정 모양의 돌기부가 형성되도록 용기부를 제작하고, 상기 용기부의 삽입부 내에 은과 주석분말을 함유한 접착제를 도포 또는 분사한 다음, 상기 삽입부와 대응되는 모양을 갖고 중앙에는 돌기부가 끼워지는 관통공이 형성된 자성강판을 삽입부에 삽입한 후, 그 상면을 고온 가압하여 분말 성분을 녹여 용기와 자성강판이 결합되도록 함을 특징으로 하는 인덕션 렌지용 주방용기의 제조방법을 제공함으로써 달성된다.The bottom surface is provided with an insertion portion bent inward, and at the same time the container portion is manufactured to form a protrusion having a predetermined shape in the center of the insertion portion, and the coating or spraying the adhesive containing silver and tin powder in the insertion portion of the container portion, Induction induction, characterized in that the magnetic plate is formed in the shape corresponding to the insertion portion and the through-hole in which the projection is inserted into the insertion portion, the upper surface is pressurized at high temperature to melt the powder component to combine the container and the magnetic steel sheet It is achieved by providing a method of manufacturing a kitchen utensil for a stove.

이하에서는 본 발명에 대하여 첨부된 도면에 도시된 실시예에 따라 구체적으로 설명하기는 하나, 본 발명이 도면에 도시된 실시예만으로 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited to the embodiments shown in the drawings.

도 3은 본 발명의 조리용기의 저면을 나타낸 분해 사시도이고, 도 4a와 4b는 도 3의 조리용기에 제조공정을 설명하기 위한 부분 단면도이다.3 is an exploded perspective view showing the bottom of the cooking vessel of the present invention, Figures 4a and 4b is a partial cross-sectional view for explaining the manufacturing process to the cooking vessel of FIG.

이에 도시된 바와 같이 본 발명의 조리용기의 제조공정은, 먼저 알루미늄이나 스테인레스를 프레스 성형을 통해 용기부(1)를 제작하는 과정에서, 상기 용기부(1) 저면에는 내부로 절곡된 삽입부(10)가 구비되며, 상기 삽입부(10) 중앙에는 소정 모양의 돌기부(11)가 형성되도록 제작한다. 이 때 상기 돌기부(11)는 삽입부(10)를 형성하는 측면과 동일높이가 되도록 하는 것이 바람직하다. As shown in the manufacturing process of the cooking vessel of the present invention, first, in the process of manufacturing the container portion 1 by pressing molding aluminum or stainless, the bottom portion of the container portion (1) inserted into the bent portion ( 10) is provided, and is formed so that the projection portion 11 of a predetermined shape is formed in the center of the insertion portion (10). At this time, the protrusion 11 is preferably to be the same height as the side surface forming the insertion portion (10).

이와 같이 제작된 용기부(1)의 삽입부(10) 내에 은과 주석분말을 함유한 접착제(20)를 도포 또는 분사한 다음, 삽입부(10)와 대응되는 모양을 갖고 중앙에는 돌기부(11)가 빈틈없이 삽입되는 관통공(31)이 형성된 자성강판(30)을 상기 삽입부(10) 내에 삽입한다. 이와 같은 자성강판(30)은 용기부(1)와 별도로 제작되며, 추가적으로 알루미늄이나 스테인레스 도금강판을 사용하여도 무방하다.Applying or spraying the adhesive 20 containing silver and tin powder in the insert portion 10 of the container portion 1 manufactured as described above, and has a shape corresponding to the insert portion 10, the projection 11 in the center ) Is inserted into the inserting portion 10, the magnetic steel plate 30 having a through hole 31 is inserted into the gap. The magnetic steel sheet 30 is manufactured separately from the container portion 1, and may be additionally used aluminum or stainless plated steel sheet.

상기와 같이 용기부(1)의 삽입부(10) 내에 자성강판(30)을 장착하고, 그 상면을 분말성분이 녹을 수 있을 만큼의 온도에서 프레스 기계로 가압하여 용기부(1)와 자성강판(30)이 결합되도록 함으로서 본 발명의 인덕션 렌지용 주방용기가 완성된다.As described above, the magnetic steel plate 30 is mounted in the insertion part 10 of the container part 1, and the upper surface of the container part 1 is pressed by a press machine at a temperature such that the powder component can be melted. By integrating the 30, the induction stove kitchen vessel of the present invention is completed.

아울러, 상기 자성강판(30)은 삽입부(10)의 높이보다 좀 더 작은 두께를 갖도록 하면 더욱 바람직한 효과를 가져오게 되는데, 이는 고온 가압과정에서 자성강판(30)과 차이가 나는 삽입부(10)와 돌기부(11)의 여유높이(h) 부분이 프레스에 의해 강제로 눌러져 자성강판(30)의 상단에 걸림턱(12)을 형성하게 되며, 이와 같은 걸림턱(12)에 의해 자성강판(30)의 탈착을 방지하여 그 고정을 더욱 단단하게 유지할 수 있다.In addition, the magnetic steel plate 30 has a more desirable effect to have a thickness smaller than the height of the inserting portion 10, which is different from the magnetic steel sheet 30 in the high temperature pressurization process (10) ) And the clearance height h of the protrusion 11 are forcibly pressed by the press to form the locking jaw 12 at the upper end of the magnetic steel plate 30, and the magnetic steel plate ( 30) can be prevented from being detached and the fixing can be maintained more firmly.

이와 같은 제조방법을 통해 제조되는 주방용기는 비자성체인 용기부에 자성강판의 결합이 종래의 용접공법이 아닌 다이캐스팅 공법을 통해 이루어지도록 하여 보다 저렴하고 대량생산이 가능하다. The kitchen container manufactured by the manufacturing method as described above is more inexpensive and mass-produced by allowing the coupling of the magnetic steel plate to the non-magnetic container part through a die casting method rather than the conventional welding method.

전술한 제조공정에 있어서, 용기부(1)와 자성강판(30)의 결합을 더욱 견고히 하기 위한 방안으로 다양한 방법이 응용될 수 있으며, 이하에서는 이에 대한 예시로 도면과 함께 설명하기로 한다.
