이하 첨부 도면들 및 첨부 도면들에 기재된 내용들을 참조하여 본 발명의 실시예를 상세하게 설명하지만, 본 발명이 실시예에 의해 제한되거나 한정되는 것은 아니다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and contents described in the accompanying drawings, but the present invention is not limited or limited by the embodiments.

도 1은 본 발명의 실시예에 따른 비자성체와 자성체가 접합된 상태의 인덕션용 용기의 단면을 도시한 것이고, 도 2는 본 발명의 실시예에 따른 비자성체와 자성체가 분리된 상태의 인덕션용 용기의 단면을 도시한 것으로서, 인덕션용 용기(100)는 비자성체(110), 자성체(120) 및 용가재(130)를 포함한다.1 is a cross-sectional view of a container for induction in a state in which a non-magnetic material and a magnetic material are bonded according to an embodiment of the present invention, and FIG. 2 is a non-magnetic material and a magnetic material for induction in a separated state according to an embodiment of the present invention As a cross-sectional view of the container, the induction container 100 includes a non-magnetic material 110 , a magnetic material 120 , and a filler metal 130 .

비자성체(110)는 자성이 없는 물질로서 오스테나이트(austenite) 계열의 금속일 수 있고, 대표적으로 STS304이다. 자성체(120)는 자성이 있는 물질로서 페라이트(ferrite) 계열의 금속일 수 있고, 대표적으로 STS430이다.The non-magnetic material 110 is a material without magnetism and may be an austenite-based metal, typically STS304. The magnetic material 120 is a magnetic material and may be a ferrite-based metal, typically STS430.

STS304와 STS430은 니켈의 포함 유무에서 차이점이 있다. STS304는 니켈을 포함하고, STS430은 니켈을 미포함한다. STS304는 니켈을 포함하여, STS430보다 뛰어난 내식성과 저온강도를 가지고 있고, 가공성이 크며, 열처리로 경화되지 않는 특징이 있다.There is a difference between STS304 and STS430 in the presence or absence of nickel. STS304 contains nickel and STS430 does not contain nickel. STS304 includes nickel and has superior corrosion resistance and low-temperature strength than STS430, has great workability, and is not hardened by heat treatment.

STS430은 성형성과 내산화선이 우수하나, 염분이나 수분 등 음식물과 접촉 시 부식성이 크다는 단점이 있으므로, 본 발명에서는 비자성체(110)의 하부에 형성되어 인덕션의 유도가열 방식으로 가열되는 용도로 사용된다.STS430 has excellent moldability and oxidation resistance, but has a disadvantage in that it is highly corrosive when in contact with food such as salt or moisture. .

용가재(130)는 비자성체(110)와 자성체(120)의 접합용도로 사용되고, 자성체(120)에서 비자성체(110)로 균일한 열전도를 실현하기 위해 사용되는 물질이고, 대표적으로 구리이다.The filler metal 130 is used for bonding the non-magnetic material 110 and the magnetic material 120 , and is a material used to realize uniform heat conduction from the magnetic material 120 to the non-magnetic material 110 , and is typically copper.

예를 들어 비자성체(110)와 자성체(120)를 일반 용접으로 접합시킨다면 비자성체(110)와 자성체(120) 사이에 공극이나 틈이 발생할 수 있고, 공극이나 틈에 의해 접착성의 감소가 발생할 수 있고, 균일한 열전도를 실현하기 어렵다. 그러나 본 발명은 용가재(130)를 용융시켜 비자성체(110)와 자성체(120) 사이에 공극이나 틈을 제거할 수 있고, 공극이나 틈이 제거되어 균일한 열전도의 실현이 가능하다.For example, if the non-magnetic material 110 and the magnetic material 120 are joined by general welding, a gap or gap may occur between the non-magnetic material 110 and the magnetic material 120, and a decrease in adhesiveness may occur due to the gap or gap. and it is difficult to realize uniform heat conduction. However, in the present invention, it is possible to remove a void or a gap between the non-magnetic material 110 and the magnetic material 120 by melting the filler metal 130 , and the void or gap is removed to realize uniform heat conduction.

본 발명은 구리가 아닌 비자성체(110)나 자성체(120)보다 낮은 용융온도를 갖는 다양한 용가재(130)의 사용이 가능하고, 다양한 용가재(130)를 사용하여 설정된 목표의 열전도율을 갖는 인덕션용 용기(100)를 제조할 수 있다.According to the present invention, it is possible to use various filler metals 130 having a lower melting temperature than the non-magnetic material 110 or the magnetic material 120 other than copper, and the induction container having a target thermal conductivity set using the various filler materials 130 . (100) can be prepared.

도 3은 본 발명의 실시예에 따른 인덕션용 용기 제조방법을 도시한 흐름도로서, 본 발명은 성형장치를 이용하여 용기 형상의 비자성체(110)를 준비하고, 판 형상의 자성체(120)와 용가재(130)를 준비한다. 본 발명은 재료의 준비가 완료되면 접합장치를 이용하여 용가재(130)를 용융시켜 비자성체(110)의 하부에 자성체(120)를 접합시켜 인덕션용 용기(100)를 제조한다.3 is a flowchart illustrating a method for manufacturing a container for induction according to an embodiment of the present invention. The present invention prepares a container-shaped non-magnetic material 110 using a molding apparatus, and a plate-shaped magnetic material 120 and a filler metal. Prepare (130). In the present invention, when the preparation of the material is completed, the filler material 130 is melted using a bonding device to bond the magnetic material 120 to the lower portion of the non-magnetic material 110 to manufacture the induction container 100 .

비자성체(110)는 음식물을 조리하기 위한 솥 형상으로 성형되고, 하부는 평평하거나 소정의 곡률을 갖는 판 형상을 가질 수 있다. 자성체(120)는 비자성체(110)의 하부의 면과 같은 판 형상을 가질 수 있다.The non-magnetic material 110 may be formed in a shape of a pot for cooking food, and may have a flat lower portion or a plate shape having a predetermined curvature. The magnetic material 120 may have the same plate shape as the lower surface of the non-magnetic material 110 .

자성체(120)와 용가재(130)는 사각형 또는 원형의 판 형상을 가질 수 있다. 본 발명은 용가재(130)를 자성체(120)보다 두께와 면적이 작게 성형함으로써, 접합 공정에서 용융된 용가재(130)가 자성체(120)의 외측으로 돌출되지 않도록 할 수 있다.The magnetic body 120 and the filler metal 130 may have a rectangular or circular plate shape. According to the present invention, by forming the filler metal 130 to have a smaller thickness and area than the magnetic body 120 , the filler metal 130 molten in the bonding process may not protrude to the outside of the magnetic body 120 .

본 발명은 자성체(120)를 비자성체(110)보다 면적을 작게 성형함으로써, 인덕션에 의한 자성체(120)를 가열 시 자성체(120)의 바닥 중심에서 외측 상부로 열의 대류를 발생시킬 수 있고, 음식물의 조리효율 또는 맛을 향상시킬 수 있다.In the present invention, by forming the magnetic material 120 to have a smaller area than the non-magnetic material 110 , when the magnetic material 120 is heated by induction, heat convection can be generated from the bottom center of the magnetic material 120 to the outer upper portion, and food Cooking efficiency or taste can be improved.

도 4는 지그를 이용하여 비자성체와 자성체를 접합시키는 예를 도시한 것으로서, 본 발명은 용가재(130)를 용융한 이후 접합할 때 일부 용가재(130)가 자성체(120)의 외측으로 흐르거나 돌출될 수 있으므로, 접합과정에서 지그(200)를 이용하여 용가재(130)가 외측으로 흐르는 것을 방지할 수 있다.4 shows an example of bonding a non-magnetic material and a magnetic material using a jig, in the present invention, when the filler material 130 is melted and then joined, some of the filler material 130 flows to the outside of the magnetic material 120 or protrudes. Therefore, it is possible to prevent the filler metal 130 from flowing outward by using the jig 200 in the bonding process.

도 5는 본 발명의 다른 실시예에 따른 비자성체와 자성체가 분리된 상태의 인덕션용 용기의 단면을 도시한 것으로서, 비자성체(110)는 밑면 제작시 외측이 라운드(R)가 생긴다. 라운드가 있는 면에 자성체(120)를 접합시킬 수 없으므로, 접합과 열의 대류를 고려하여 자성체(120)의 밑면은 비자성체(110)의 밑면보다 면적이 작을 수 있다.5 is a cross-sectional view of a container for induction in a state in which the non-magnetic material and the magnetic material are separated according to another embodiment of the present invention, and the non-magnetic material 110 has a round (R) on the outside when the bottom surface is manufactured. Since the magnetic material 120 cannot be bonded to the round surface, the bottom surface of the magnetic material 120 may have a smaller area than the bottom surface of the non-magnetic material 110 in consideration of bonding and heat convection.

종래에는 적층가열판으로 압연공정을 할 때 약 660도 등 알루미늄의 녹는점 이하에서 용기를 제조하였다. 그러나 본 발명은 약 1085도 등 구리의 녹는점으로 용융시킬 수 있으므로, 온도의 제약이 없이 넓은 온도범위로 용기를 제조할 수 있다.Conventionally, a container was manufactured at a temperature below the melting point of aluminum, such as about 660 degrees Celsius, when the rolling process was performed with a laminated heating plate. However, since the present invention can be melted at a melting point of copper such as about 1085 degrees, a container can be manufactured in a wide temperature range without temperature restrictions.
