본 발명은 전자유도밥솥용 내솥에 관한 것이다.The present invention relates to an inner pot for an electromagnetic induction cooker.

일반적으로 전기보온밥솥(電氣保溫-, electric rice cooker)은 전기에너지를 열에너지로 변환시켜 자동으로 밥을 짓는 솥을 말하는 것이다.In general, electric rice cooker (電氣 保溫-, electric rice cooker) refers to a pot that automatically cooks rice by converting electrical energy into thermal energy.

전기밥솥의 가열방식은 크게 열판식과 전자유도(Induction Heating) 방식으로 나눌 수 있습니다. 열판식의 경우, 밥솥 내부에 열을 공급하는 열판이 있고 그 열판 위에 물을 담는 내솥이 있어 취사 시 내솥에 쌀과 적당한 물을 채우고 뚜껑을 닫은 후 스위치를 작동시키면 됩니다. 스위치 작동과 동시에 열판 내부의 히타에 통전돼 열판이 가열되고 가열된 열판의 열이 내솥에 전달돼 내솥 내 온도는 100℃로 상승하고 밥이 끓게 됩니다. 이후 내솥 내부 밥이 끓는 물의 온도는 더욱 상승해 일정온도(약 120℃)에 도달하게 되고 일정시간 경과 후 스위치가 자동으로 커지 며 취사 공정이 완료됩니다. 그리고 밥솥의 옆면 및 뚜껑부에 설치된 보온히터가 발열을 시작해 보온을 시작하게 됩니다.The heating method of electric rice cooker can be divided into heat plate type and induction heating method. In the case of the hot plate type, there is a hot plate to supply heat inside the rice cooker, and there is an inner pot to hold water on the hot plate. When cooking, fill the inner pot with rice and proper water, close the lid, and operate the switch. As soon as the switch is activated, the heater is energized and the hot plate is heated, and the heat from the heated hot plate is transferred to the inner pot so that the temperature in the inner pot rises to 100 ° C and the rice boils. After that, the temperature of boiling water in the inner pot rises further to reach a certain temperature (about 120 ℃), and after a certain time, the switch automatically increases and the cooking process is completed. And the heating heater installed on the side and the lid of the rice cooker starts to heat and start warming.

또한, 전자유도 방식은 가열되는 가열부분에 형성된 코일에 전류를 보내면 코일의 자력선이 발생하고, 이 자력선이 상부에 형성된 용기의 하부를 통과하면 용기에 재질에 포함된 저항성분(철성분)에 의해 와류전류가 발생하고, 이렇게, 발생된 와류전류는 용기만을 발열시킴에 따라 용기를 제외한 다른 부품으로 열에너지가 절달되지 않고 용기만 뜨거워지는 유도가열이 발생하고 내솥과 코일의 접촉을 제거하면 즉시 가열을 멈추게 됨으로 안전하고 용기 부분만 가열됨에 따라 에너지효율이 높아 전기를 절약하며, 다른 부품에 열전달이 적게 발생하여 수명을 증대시킨다.In addition, in the electromagnetic induction method, when a current is sent to the coil formed in the heating part to be heated, a magnetic force line of the coil is generated, and when the magnetic force line passes through the lower part of the container formed at the upper part, the resistance component (iron component) contained in the material in the container As the eddy current occurs, the generated eddy current heats only the container, so that induction heating occurs that heat is not delivered to other parts except the container, and only the container heats up. It is safe to stop and heats only the container part, which saves electricity due to its high energy efficiency.

상기와 같은, 전자유도방식을 이용한 밥솥은 가열되는 용기를 쌀이 안치되는 내솥으로 형성하여 내솥의 측면에 구리코일을 감은 후 강한 전류를 흘려 보내면 코일 주위에 자력선이 형성돼 내솥 전체를 가열하는 방식으로 솥 전체가 통째로 가열돼 쌀알 하나 하나까지 골고루 익혀 줘 윤기 있고 맛있는 밥을 만들 수 있는 장점이 있다.As described above, the rice cooker using the electromagnetic induction method is formed in the inner pot is heated rice is placed in the inner pot to wrap the copper coil on the side of the inner pot and send a strong current to form a magnetic line around the coil to heat the entire inner pot The whole pot is heated so that every grain of rice is cooked evenly so that it can make shiny and delicious rice.

이러한, 전자유도방식의 밥솥의 내부에서 직접 가열되는 종래기술의 전자유도압력밥솥용 내솥을 도 1 및 도 2에서 도시한 바, 이를 참조하면서 살펴보면 다음과 같다.Such, the inner pot for the electromagnetic induction pressure cooker of the prior art that is directly heated in the interior of the electromagnetic induction cooker bar as shown in Figures 1 and 2, with reference to this as follows.

전자유도방식의 밥솥의 내부에 장착되는 내솥용기(10)는 상기 유도가열식에 의해 가열되기 위해서는 반드시 자성체일 필요는 없지만 코일에 발전되는 전계에 유도전류가 발생될 수 있도록 전도성 재질로 이루어지는데, 이를 위해 상기 내솥용기(10)는 부식방지를 위해 스테인리스 등의 철계금속으로 이루어진 외층부재(14)와, 열전달이 우수하고 무게가 가벼운 알루미늄 등의 비철계금속으로 이루어진 내층부재(12)로이루어진다.The inner pot container 10 mounted inside the electromagnetic induction cooker is not necessarily a magnetic material to be heated by the induction heating type, but is made of a conductive material so that an induced current can be generated in an electric field generated in a coil. The inner pot container 10 is made of an outer layer member 14 made of iron-based metals such as stainless steel and the inner layer member 12 made of non-ferrous metals such as aluminum having excellent heat transfer and light weight to prevent corrosion.

또한, 상기 내층부재(12)는 음식물과 직접 접촉되는 부분에 음식물이 눌어붙지 않도록 코팅처리된다.In addition, the inner layer member 12 is coated so that the food does not stick to the portion in direct contact with the food.

상기와 같이 구성된 내부용기의 제작방법은 먼저 내층부재(12)를 판 형태로 이루어진 알루미늄계의 제 1금속판(M1)과 외층부재(14)를 이루는 스테인리스계의 제 2금속판(M2)을 준비한다.In the method of manufacturing the inner container configured as described above, first, an inner layer member 12 is prepared from a stainless steel-based second metal plate M2 constituting an aluminum-based first metal plate M1 and an outer layer member 14. .

상기와 같이 내층부재(12)와 외층부재(14)는 서로 다른 종류의 금속으로 이 루어지는 바, 열전달이 효과적으로 전달될 수 있도록 상기 제 1금속판(M1)과 상기 제 2금속판(M2)을 상부롤러(20)와 하부롤러(22)를 포함하는 압연시설을 사용하여 고압으로 압연시켜 상기 제 1금속판(M1)과 상기 제 2금속판(M2)이 일체로 형성되도록 한다.As described above, the inner layer member 12 and the outer layer member 14 are made of different kinds of metals, and the upper part of the first metal plate M1 and the second metal plate M2 so that heat transfer can be effectively transmitted. The first metal plate M1 and the second metal plate M2 are integrally formed by rolling at a high pressure using a rolling facility including a roller 20 and a lower roller 22.

상기와 같이 압연된 상기 제 1금속판(M1)과 제 2금속판(M2)은 상기 내층부재(12)와 외층부재(14)를 이루는 원형의 플레이트(P) 형태로 가공되고, 내솥형상과 동일하게 형성된 상부금형(25)과 하부금형(26)에 의해 적정압력으로 압축되며 내솥용기로 형성된 후 취출된다.The first metal plate M1 and the second metal plate M2 rolled as described above are processed into a circular plate P forming the inner layer member 12 and the outer layer member 14, and have the same shape as the inner pot shape. The upper mold 25 and the lower mold 26 formed are compressed to a proper pressure, and then formed into an inner pot container and then taken out.

그러나, 열전달이 우수하고 무게가 가벼운 알루미늄 등의 비철계금속으로 이루어진 내층부재의 외측으로 코일에 발전되는 전계에 유도전류가 발생될 수 있도록 전도성 재질로 이루어지는 외층부재를 철계금속 중에 부식방지가 뛰어난 스테인레스로 제작하였으나, 스테인레스의 열전도성이 현저히 감소되어 유도된 전류에 의한 와류전류에서 발생되는 열이 외층부재에서 열전달이 잘 이루어지지 않아 열손실이 발생되는 문제점이 있었다.However, stainless steels having excellent corrosion protection in iron-based metals are made of an outer layer member made of a conductive material so that an induced current can be generated in an electric field generated in a coil outside of an inner layer member made of a non-ferrous metal such as aluminum having excellent heat transfer and light weight. However, the thermal conductivity of the stainless steel is significantly reduced, the heat generated in the eddy current caused by the induced current is not a good heat transfer in the outer layer member has a problem that heat loss occurs.

이에, 최근에는 스테인레스의 열전도성을 향상시키도록 외부를 도금한 전자유도밥솥용 코팅내솥이 개시된 바, 이를 도 3을 참조하면서 살펴보면 다음과 같다.Thus, recently, the coating inner pot for electro-induction cooker plated outside to improve the thermal conductivity of stainless bar is disclosed, looking at this with reference to FIG.

전기밥솥의 내부에서 코일가열부(2)로 전자유도되어 가열 조리하는 내솥용기(10)는 열전도성이 뛰어나면서 가벼운 소재인 알루미늄계로 형성된 내층부재(12)의 내측으로 조리되는 조리물의 접촉에 의한 오염을 방지하는 내부코팅부(11)를 형성하고, 내층부재(12)의 외측으로 코일가열부(2)에서 자성체의 유도에 열을 발산하도록 내부식성이 뛰어난 전도성 물질을 스테인레스계로 형성된 외층부재(14)를 형성하며, 외층부재(14)의 외측으로 열전도율을 향상시키는 소재인 황동도금층(15a)과 황금도금층(15b)으로 형성된 외부코팅층(15)으로 구비한다.The inner pot container 10 that is electromagnetically induced and cooked by the coil heating unit 2 in the inside of the rice cooker has excellent thermal conductivity and is caused by contact of food cooked inside the inner layer member 12 formed of aluminum, which is a light material. The inner layer 11 is formed to prevent contamination, and the outer layer member formed of stainless steel is formed of a conductive material having excellent corrosion resistance so as to dissipate heat in the induction of the magnetic material from the coil heating unit 2 to the outside of the inner layer member 12 ( 14) and the outer coating layer 15 formed of a brass plating layer 15a and a golden plating layer 15b, which are materials for improving thermal conductivity to the outside of the outer layer member 14.

상기와 같이, 내부식성이 뛰어난 스테인레스계의 외층부재의 열전도율을 향상시키기 위해서 황동 및 황금을 도금한 외부코팅층을 형성하여 코일가열부의 전자유도에 의해 자성체인 외층부재에서 유도된 전류에 의한 와류전류에서 발생되는 열을 내층부재로 전달시켜 내솥을 가열하도록 한다.As described above, in order to improve the thermal conductivity of the stainless steel outer layer member having excellent corrosion resistance, an outer coating layer coated with brass and gold is formed, and in the eddy current caused by the current induced in the outer layer member which is magnetic by the electromagnetic induction of the coil heating unit. The generated heat is transferred to the inner layer member to heat the inner pot.

그러나, 종래기술의 전자유도밥솥용 코팅내솥의 내솥용기는 내부식성이 뛰어난 스테인레스계의 외층부재의 열전도성이 매우 낮음에 따라 외측으로 열전도성이 뛰어난 황동 및 황금을 도금하여도 도금청의 두께가 너무 얇아 열에너지의 효율을 향상시키는 효과가 미약하고, 내부식성이 강하여 황동이나 황금 도금 작업이 어려워 공정이 기간이 증대하여 생산성이 저하되는 문제점이 있었다.However, since the inner pot container of the coated inner pot for the electromagnetic induction cooker of the prior art has a very low thermal conductivity of the outer layer member of stainless steel having excellent corrosion resistance, the thickness of the plated blue is too high even when plating brass and gold having excellent thermal conductivity to the outside. It is thin and the effect of improving the efficiency of thermal energy is weak, the corrosion resistance is strong, brass or golden plating is difficult to work, there is a problem that the process is increased, the productivity is reduced.

또한, 종래기술에 전자유도밥솥용 코팅내솥의 내솥용기는 전자유도가열을 위해 사용되는 부위가 코일가열부에 국한적으로 사용되는데 반하여, 전자유도를 위해 사용되는 열전도성을 향상시키는 외부코팅층이 구비된 외층부재가 필요이상 사용되므로 재료비가 증대되고, 가공에 따른 생산비용이 증대되는 문제점이 있었다.In addition, the inner pot container of the coating inner pot for the electromagnetic induction cooker in the prior art is provided with an outer coating layer to improve the thermal conductivity used for electromagnetic induction, while the portion used for the electromagnetic induction heating is limited to the coil heating portion. Since the outer layer member is used more than necessary, there is a problem in that the material cost is increased and the production cost due to processing is increased.

그리고, 종래기술의 전자유도밥솥용 코팅내솥의 내솥용기는 외층부재로 형성된 스테인레스계 부재는 내부식성이 아주 뛰어나지만, 유도가열장치에 필수요소인 페라이트조직과 투자율이 일반적인 금속과 비교하여 현저하게 낮아 전자유도 방식의 와류전류 발생으로 인한 열효율이 저하되는 문제점이 있었다.In addition, the inner pot container of the coated inner pot for the electromagnetic induction cooker of the prior art has excellent corrosion resistance, but the stainless steel member has excellent corrosion resistance, but the ferrite structure and permeability, which are essential elements of the induction heating apparatus, are significantly lower than those of the general metals. There was a problem that the thermal efficiency is lowered due to the eddy current generation of the electromagnetic induction method.

또한, 종래기술의 전자유도밥솥용 코팅내솥의 내솥용기는 내솥용기의 전부분이 가열됨에 따라 음식물의 조리시 내용물의 량이 달라짐에 따라 내부온도를 균일하게 관리하는데 곤란한 문제점이 있었다.In addition, the inner pot container of the coating inner pot for the electromagnetic induction cooker of the prior art has a problem that it is difficult to uniformly manage the internal temperature as the amount of the contents of the food is changed as the whole portion of the inner pot container is heated.

그리고, 종래기술의 전자유도밥솥용 코팅내솥의 내솥용기는 중량물인 스테인레스 계의 외층부재를 외측에 형성하여 밥솥에 무게가 무거워 취급이 어려운 문제점이 있었다.In addition, the inner pot container of the coated inner pot for the electromagnetic induction cooker of the prior art has a problem that it is difficult to handle because the weight of the rice cooker is formed by forming the outer layer member of the stainless steel based on the outside.

아울러, 종래기술의 전자유도밥솥용 코팅내솥의 내솥용기는 알루미늄계의 내층부재와 스테인레스계의 외층부재를 이중으로 형성하기 위해서, 외층부재와 내층부재의 압착을 위해 고가의 압연장비가 필요하므로 이를 위해 설치 공간 및 비용이 소요되고, 상기 외층부재와 내층부재의 압축성형시 변형률의 차이가 발생되므로, 변형률을 최소화하기 위해서는 서행 압축해야하므로 작업시간이 증가됨은 물론 제작비용이 증가되는 문제점이 있었다.In addition, the inner pot container of the coating inner pot for the electromagnetic induction cooker of the prior art, in order to form the inner layer member of the aluminum and the outer layer member of the stainless steel double, since expensive rolling equipment is required for the compression of the outer layer member and the inner layer member. In order to take the installation space and cost, and the difference in strain occurs during compression molding of the outer layer member and the inner layer member, it is necessary to slow the compression to minimize the strain, there is a problem that the work time is increased as well as the manufacturing cost increases.

이와 같은, 문제점을 해결하고자 안출된 본 발명의 주목적은 전자유도밥솥의 내솥을 단일부재인 알루미늄재로 형성하고, 하부에 전자유도되는 코일가열부에 부식방지층으로 부식이 방지되는 부식방지층이 구비된 페라이트조직과 투자율이 뛰어난 저탄소강재의 자성층을 접착층으로 용착시켜 단일부재로 제작비를 감소하고 생산성을 향상시키며, 전자유도효율을 향상하여 열효율을 증대시키는 효과를 제공한다.In order to solve the above problems, the main object of the present invention is to form the inner pot of the electromagnetic induction cooker with a single member of the aluminum material, the lower portion is provided with a corrosion prevention layer to prevent corrosion as a corrosion prevention layer in the coil heating portion induced by the lower portion.
