Description

유도가열이 가능한 주방용기 및 그 제조방법Induction heating capable kitchen vessel and its manufacturing method
본 발명은 주방용기 및 그 제조방법에 관한 것으로서, 더 상세하게는 유도가열이 가능한 주방용기 및 그 제조방법에 관한 것이다. The present invention relates to a kitchen container and a method for manufacturing the same, and more particularly, to a kitchen container capable of induction heating and a method for manufacturing the same.
코일에서 발생한 자력선이 유도가열이 가능한 주방용기를 통과할 때 주방용기를 구성하는 물질의 저항성분에 의해서 와류전류가 생성되며, 이러한 와류전류는 상기 저항성분에 의해서 열로 변환되므로 주방용기 자체가 발열되어 조리가 수행될 수 있다. When the magnetic force line generated from the coil passes through the kitchen vessel capable of induction heating, eddy current is generated by the resistance component of the material constituting the kitchen vessel, and the eddy current is converted into heat by the resistance component, so the kitchen vessel itself generates heat. Cooking can be performed.
금속을 함유하여 이루어진 주방용기의 유도가열은 특정한 주파수에서 발생되며 통상적으로 알루미늄 주방용기는 유도가열이 일어나지 않는다. 따라서 무게가 가벼워 많이 사용되는 알루미늄 주방용기에 유도가열의 적용은 기술적 해결이 요구된다. Induction heating of a kitchen vessel made of metal occurs at a specific frequency, and typically aluminum kitchen vessels do not induction heating. Therefore, the application of induction heating to aluminum kitchenware, which is widely used due to its light weight, requires a technical solution.
알루미늄 주방용기에 유도가열을 구현하기 위하여 용기 밑판에 철판 클래딩기술이 시도되었다. 이 기술의 문제점으로 알루미늄판과 클래딩 철판의 열팽창 차이로 용기의 반복된 가열 사용시 철판이 이탈되거나 변형되는 문제가 발생되었다. In order to implement induction heating in an aluminum kitchenware, an iron plate cladding technique was attempted on the bottom of a container. The problem with this technique is that the difference between the thermal expansion of the aluminum plate and the cladding iron plate causes the iron plate to deviate or deform upon repeated use of the container.
알루미늄 주방용기에 유도가열을 구현하기 위한 다른 기술적 방법으로 알루미늄 밑판에 철 용사코팅을 수행하는 방법이 시도되었다. 이러한 용사코팅 기술을 적용하는 경우, 완성품이 불량인 경우 부분적인 수리(repair)가 불가능하여 완성품 전체를 폐기해야 하기 때문에 제조단가가 높아지는 문제가 발생되며, 용사코팅의 특성상 알루미늄 주방용기의 두께가 얇으면 용사과정의 열에 의한 변형이 심해져서 사용할 수 없어 일정한 두께 이상이 필요하므로 경량화를 위한 얇은 두께의 알루미늄 주방용기 사용이 제한되는 문제가 발생된다. As another technical method for implementing induction heating in an aluminum kitchen dish, a method of performing iron spray coating on an aluminum base plate has been attempted. In the case of applying the thermal spray coating technology, if the finished product is defective, a partial repair (repair) is impossible, and the entire manufacturing product must be disposed of, resulting in a high manufacturing cost, and the thickness of the aluminum kitchenware is thin due to the characteristics of the thermal spray coating. If the thermal deformation of the thermal spray process is severe and can not be used because a certain thickness or more is required, there is a problem that the use of a thin aluminum kitchen vessel for light weight is limited.
상술한 바와 같이, 알루미늄 주방용기는 기존의 상용 주파수 영역에서 유도가열이 구현되지 않는다. 본 발명은 알루미늄 유도가열을 위한 철재의 열피로 문제와 용사코팅의 제조단가 및 경량화 문제를 해결하기 위한 것으로서, 알루미늄 밑판에 유도가열이 구현되는 균일하고 안정된 코팅 기술이 적용된 주방용기 및 그 제조방법을 제공하는 것을 목적으로 한다. 그러나 이러한 과제는 예시적인 것으로, 이에 의해 본 발명의 범위가 한정되는 것은 아니다.As described above, the aluminum kitchen vessel is not implemented induction heating in the existing commercial frequency range. The present invention is to solve the problem of thermal fatigue of the iron material for aluminum induction heating, the manufacturing cost and light weight of the thermal spray coating, a kitchen vessel and a method of applying a uniform and stable coating technology induction heating is implemented on the aluminum base plate It aims to provide. However, these problems are exemplary, and the scope of the present invention is not limited thereby.

Comparative Example 3 (100㎛ Plating Layer) Induction range recognized but shorted
Experimental Example 1 (150㎛ Plating Layer) 5 to 5 minutes to 10 ° C, 10 seconds (550mL, 1800w)
Experimental Example 2 (200㎛ Plating Layer) 4 minutes 30 ~ 40 seconds to 550 ° C (550mL, 1800w)

표 2를 참조하면, 용기 몸체부의 외측 바닥면에 20㎛의 도금층이 형성된 경우 인덕션 레인지가 인식을 못하여 유도 가열이 수행되지 않았으며, 용기 몸체부의 외측 바닥면에 100㎛의 도금층이 형성된 경우 인덕션 레인지가 인식은 하였으나 단락되어 유도가열이 원활하게 수행되지 않았다. 한편, 용기 몸체부의 외측 바닥면에 150㎛ 또는 200㎛의 도금층이 형성된 경우 인덕션 레인지가 단락없이 인식하여 유도가열이 원활하게 수행되었다. 예를 들어, 150㎛의 도금층에서는 1800W의 전력으로 550mL 용량의 물의 온도를 상온에서 90℃까지 상승시키는데 5분 내지 5분 10초가 소요되었으며, 200㎛의 도금층에서는 1800W의 전력으로 550mL 용량의 물의 온도를 상온에서 90℃까지 상승시키는데 4분 30초 내지 4분 40초가 소요되었는바, 도금층의 두께가 150㎛ 보다는 200㎛일 때 유도가열이 더 효과적으로 수행됨을 확인할 수 있었다. Referring to Table 2, induction range was not recognized because the induction range was not recognized when the plating layer of 20 μm was formed on the outer bottom of the container body, and induction range was not performed when the plating layer of 100 μm was formed on the outer bottom of the container body. Was recognized, but short-circuited, the induction heating was not smooth. On the other hand, when the plating layer of 150㎛ or 200㎛ formed on the outer bottom surface of the container body portion, the induction range was recognized without a short circuit and induction heating was performed smoothly. For example, it takes 5 minutes to 5 minutes and 10 seconds to raise the temperature of a 550 mL capacity at room temperature to 90 ° C. with a power of 1800 W in a 150 μm plated layer, and a temperature of 550 mL capacity at a power of 1800 W in a 200 μm plated layer. It took 4 minutes 30 seconds to 4 minutes 40 seconds to increase to 90 ℃ at room temperature, it was confirmed that the induction heating is more effectively performed when the thickness of the plating layer is 200㎛ than 150㎛.
비교예4 및 비교예5에서는, 용기 몸체부의 외측 바닥면에 20㎛ 또는 50㎛의 도금층이 형성된 경우, 샌드 블래스팅 공정에서 도금층의 필링(peeling) 현상이 일어남을 확인할 수 있었다. 비교예6에서는, 100㎛의 도금층 및 세라믹 코팅층을 포함하는 주방용기는 인덕션 레인지가 인식하지 못하였으며, 도금층의 일부가 떨어져 부풀어 오르는 현상이 일어남을 확인할 수 있었다. 실험예3 및 실험예4에서는, 150㎛ 또는 200㎛ 두께의 도금층을 형성한 후에 샌드 블래스팅 공정을 수행할 경우 도금층의 필링 현상이 일어나지 않음을 확인하였다. In Comparative Examples 4 and 5, when a plating layer having a thickness of 20 μm or 50 μm was formed on the outer bottom surface of the container body part, it was confirmed that a peeling phenomenon of the plating layer occurred in the sand blasting process. In Comparative Example 6, the kitchen vessel including the 100 μm plating layer and the ceramic coating layer was not recognized by the induction range, and it was confirmed that a phenomenon in which a portion of the plating layer fell off and swelled. In Experimental Example 3 and Experimental Example 4, it was confirmed that the peeling phenomenon of the plating layer did not occur when the sand blasting process was performed after forming the plating layer having a thickness of 150 μm or 200 μm.
실험예3에 개시된 150㎛ 두께의 도금층 상에 세라믹 코팅층을 형성한 유도가열이 가능한 주방용기를 인덕션 레인지 상에 배치한 후에 2100W의 전력으로 550mL 용량의 물을 끓이는 실험을 10회 반복하여 수행한 결과를 표 3에서 요약하였다. 온도가 올라가는데 시간이 많이 소요되어 온도구간은 60℃까지 측정하였다. 이에 따르면, 예를 들어, 150㎛ 두께의 도금층과 세라믹 코팅층이 형성된 유도가열이 가능한 주방용기에 수용된 물을 유도가열하여 30℃에서 60℃까지 올리는 데 소요되는 시간은 평균적으로 4분 29초로 나타났다. After placing the kitchen vessel capable of induction heating on which the ceramic coating layer was formed on the 150 μm-thick plating layer disclosed in Experiment 3 on the induction range, the experiment was repeated 10 times of boiling water of 550 mL capacity at a power of 2100 W. Are summarized in Table 3. It takes a long time to increase the temperature, the temperature range was measured up to 60 ℃. According to this, for example, the time required to raise the water contained in the kitchen container capable of induction heating on which a 150 μm-thick plating layer and a ceramic coating layer were formed was raised from 30 ° C. to 60 ° C. on an average of 4 minutes 29 seconds.
