Description

인덕션 렌지용 용기Induction Range Containers
본 발명은 용기에 관한 것으로, 특히 인덕션 렌지에 사용할 수 있는 용기에 관한 것이다.The present invention relates to a container, and more particularly to a container that can be used in an induction stove.
최근에 많이 보급되고 있는 인덕션 렌지는 자기장을 이용하여 유도전류에 의해 용기를 가열함으로써 불꽃이 발생하지 않아 화재의 위험성이 없는 장점이 있다.Induction stoves, which are widely used in recent years, have the advantage that there is no danger of fire because no flame is generated by heating a container by an induced current using a magnetic field.
도1은 공개특허 제10-2005-0108121호에 나타난 인덕션 렌지용 용기를 보인 것으서, 인덕션렌지용 용기(21)는, 그 바닥판 중앙에 관통구멍(25a)이 형성되어 있는 외부용기(25)와, 상기 관통구멍(25a)의 내부에 삽입 고정되는 자성판(27)과, 상기 외부용기(25)의 내부에 위치하며 바닥판 저면이 상기 자성판(27)에 밀착 고정되는 내부용기(23)를 포함하여 구성된다.1 shows an induction stove container shown in Korean Patent Laid-Open Publication No. 10-2005-0108121, wherein the induction stove container 21 has an outer container 25 having a through hole 25a formed in the center of its bottom plate. ), A magnetic plate 27 inserted into and fixed to the inside of the through hole 25a, and an inner container which is located inside the outer container 25 and whose bottom surface is tightly fixed to the magnetic plate 27 ( 23).
또한, 내부용기(23)의 벽면과 외부용기(25)의 벽면 사이에 공간부(29)가 마련되어 있다. 상기 공간부(29)는 용기(21)의 벽면을 통해 열이 잘 통과하지 못하게 하는 하나의 단열층이다.In addition, a space portion 29 is provided between the wall surface of the inner container 23 and the wall surface of the outer container 25. The space portion 29 is one heat insulation layer that prevents heat from passing well through the wall surface of the container 21.
그런데 이러한 인덕션 렌지에 사용되는 용기는 고주파 유도 자기장에 반응하는 금속(주로 스테인레스)으로 제조되어 있는데, 이러한 스테인레스 재질의 용기는 열전달이 매우 잘 되므로, 공간부(29)에 의해 외부로 열전달을 방지한다 할지라도 공간부(29)에 정체된 공기가 내부용기(23)의 열기로 가열되고, 이 가열된 상태가 오래 지속되므로 외부용기(25)까지 가열된다.By the way, the container used for the induction stove is made of a metal (mainly stainless steel) in response to the high frequency induction magnetic field, the stainless steel container is very good heat transfer, thereby preventing heat transfer to the outside by the space 29. Even if the air stagnated in the space 29 is heated by the heat of the inner container 23, and this heated state lasts for a long time, it is heated to the outer container 25.
이로 인해 즉, 인덕션 렌지의 사용 후 유도 자기장을 발생한 상부 플레이트는 열이 가해지지 않아서 뜨겁지 않으므로, 사용자, 유아나 아동들이 방심하고 가열된 외부용기에 접촉하여 쉽게 화상을 입는 경우가 매우 많다. Because of this, that is, the upper plate that generates the induction magnetic field after the use of the induction stove is not hot because it is not heated, so users, infants or children are often injured and easily burned in contact with the heated outer container.
상기의 문제점을 해결하고자 하여, 내부용기와 외부용기 사이의 공간부에 방열판을 구비함으로써 유동하는 공기와의 열교환에 의해 외부용기를 빨리 냉각시킴으로써 화상을 방지하도록 한 인덕션 렌지용 용기를 제공하는데 그 목적이 있다.In order to solve the above problems, by providing a heat sink in the space between the inner container and the outer container to provide a container for induction stove to prevent burns by quickly cooling the outer container by heat exchange with the flowing air. There is this.

도2는 본 발명의 정면도로서, 절개된 일부 단면을 보여주는 도이고, 도3은 본 발명의 평단면 구조로서, 본 발명의 용기(100)는 내부용기(110)와 외부용기(120)로 구성된다.Figure 2 is a front view of the present invention, showing a partial cross-section cut, Figure 3 is a planar cross-sectional structure of the present invention, the container 100 of the present invention consists of an inner container 110 and an outer container 120 do.
내부용기(110)는 바닥판과 측벽으로 이루어져서 내부공간을 제공하여 음식물을 수용하게 되고, 인덕션 렌지로부터 제공되는 고주파 유도 자기장에 반응하여 가열됨으로써 음식물을 가열하여 조리하게 된다.The inner container 110 is composed of the bottom plate and the side wall to provide the inner space to accommodate the food, and is heated and cooked by heating in response to the high frequency induction magnetic field provided from the induction stove.
이러한 내부용기(110)는 주로 스테인레스 재질로 형성된다.The inner container 110 is mainly formed of a stainless material.
상기 내부용기(110)의 바닥판을 제외한 외측방향 둘레로는 외부용기(120)가 씌워지는데, 이러한 외부용기(120)의 상측과 하측부위는 내부용기(110)의 외측에서 상측과 하측부위에 용접 또는 열접합 등에 의해 각각 고정되어 지지된다.The outer container 120 is covered with an outer circumference except for the bottom plate of the inner container 110. The upper and lower portions of the outer container 120 are located on the upper and lower portions of the outer container 110 from the outside. Each is fixed and supported by welding or thermal bonding.
이때 내부용기(110)로부터 외부용기(120)가 이격되어 위치함으로서 내부용기(110)의 외측부위와 외부용기(120)의 내측부위 사이에는 공간부(130)가 형성된다.At this time, since the outer container 120 is spaced apart from the inner container 110, a space 130 is formed between the outer part of the inner container 110 and the inner part of the outer container 120.
이 공간부(130)의 상측 또는 하측, 또는 상하측 모두에는 외부와 연통되도록 둘레를 따라서 다수의 구멍이 형성되는데, 이러한 구멍은 외부용기(120)의 상측부위 또는 하측부위에 형성될 수 있다.A plurality of holes are formed along the periphery so as to communicate with the outside at the upper side or the lower side, or both the upper side and the lower side of the space 130, and these holes may be formed at the upper side or the lower side of the outer container 120.
따라서, 이러한 구멍을 통하여 외부의 공기가 공간부(130)로 드나들면서 외부용기(120)를 냉각시키게 된다.Therefore, the outside air enters the space 130 through the hole to cool the outer container 120.
외부용기(120)의 빠른 냉각을 위하여 공간부(130)에는 방열판(140)이 형성되어 있는데, 이러한 방열판(140)은 열전달율이 높은 스테인레스, 구리 등의 재질로 형성되며, 그 구조는 'A'의 확대도에서와 같이 판재가 수직방향으로 주름형태로 접혀지면서 내부용기(110)의 외측둘레를 따라 설치되는 구조이다.The heat sink 140 is formed in the space 130 for fast cooling of the outer container 120. The heat sink 140 is formed of a material such as stainless steel or copper having a high heat transfer rate, and the structure is 'A' As shown in the enlarged view of the plate is folded along the fold in the vertical direction structure is installed along the outer circumference of the inner container (110).
또한, 방열판(140)의 주름진 첨단부위는 각각 내부용기(110)의 외측면과 외부용기(120)의 내측면에 접하여서 용접 또는 열접합 등에 의해 고정되는 구조이다. In addition, the corrugated tip portion of the heat sink 140 is in contact with the outer surface of the inner container 110 and the inner surface of the outer container 120 is fixed by welding or thermal bonding or the like.
따라서, 조리가 종료되어 인덕션 렌지가 꺼지게 되면, 내부용기(110)는 자체의 단열성에 의해 조리된 음식을 보온하게 되고, 공간부(130)를 통해 외부용기(120)에 가해진 열은 방열판(140)과 열교환하게 되어 냉각된다.Therefore, when the cooking is terminated and the induction stove is turned off, the inner container 110 keeps the food cooked by its thermal insulation, and the heat applied to the outer container 120 through the space 130 is the heat sink 140. Heat exchange with) to cool.
이때 방열판(140)의 주름은 상하방향으로 수직하게 형성되어 있으므로, 공기의 유통이 원할하여 공간부(130)로 유입되는 외부공기에 의해 방열판(140)이 빠르게 냉각되고, 이로인해 외부용기(120) 또한 빠르게 냉각되어 화상의 위험이 현저히 감소하게 된다.At this time, since the wrinkles of the heat sink 140 are formed vertically in the vertical direction, the heat sink 140 is quickly cooled by the external air flowing into the space 130 due to the smooth flow of air, and thus the external container 120 ) It also cools quickly, which significantly reduces the risk of burns.
