Description

인덕션 레인지용 히팅 모듈 및 이를 포함하는 인덕션 레인지Heating module for induction range and induction range including the same
본 발명은 인덕션 레인지에 관한 것으로서, 더욱 상세하게는 인덕션 레인지에서 가열을 위해 교번 자기장을 발생시키는 히팅 모듈에 관한 것이다.The present invention relates to an induction range, and more particularly, to a heating module for generating an alternating magnetic field for heating in an induction range.
인덕션 레인지(induction range)는 유도 가열(Induction heating)의 원리를 이용한 조리용 가열기구이다. 인덕션 레인지는 금속 재질의 용기를 주변위 위치시킨 상태에서 유도 코일에 교류 전류를 인가하여 교번 자기장을 발생시킨다. 교번 자기장에 의해 금속 재질의 용기에는 와전류(Eddy current)가 형성되고, 용기의 전기저항에 의한 열이 발생한다. 인덕션 레인지는 불꽃이나 유해가스를 발생시키지 않기 때문에 화재의 위험성이 적고, 연소 과정을 거치지 않으므로 일산화탄소의 발생이 없는 장점이 있다.An induction range is a heating appliance for cooking using the principle of induction heating. The induction range generates an alternating magnetic field by applying an alternating current to the induction coil in a state where a metal container is placed around it. An eddy current is formed in the metal container by the alternating magnetic field, and heat is generated by the electrical resistance of the container. Since the induction range does not generate flames or harmful gases, there is little risk of fire, and since it does not go through a combustion process, there is an advantage in that there is no generation of carbon monoxide.
종래의 인덕션 레인지에서 사용되는 유도 코일은 여러 가닥의 구리 세선을 꼬아서 형성한 연선을 인덕션 레인지의 형상에 맞게 원판 상에 감아서 형성되는 것이 일반적이다.The induction coil used in the conventional induction range is generally formed by winding a twisted wire formed by twisting several fine copper wires on a disk to match the shape of the induction range.
그러나, 종래의 구리 재질 코일은 사용 시 발생하는 고주파 노이즈를 제거하기 위한 별도 구성인 페라이트 코어를 필요로 하고, 베이스에 장착하는 과정을 통해 설치되기 때문에 설치 구조가 복잡하고 설치 작업이 까다롭다.However, the conventional copper coil requires a ferrite core, which is a separate component for removing high-frequency noise generated during use, and is installed through a process of mounting to the base, so the installation structure is complicated and the installation operation is difficult.
본 발명의 목적은 구조가 단순하면서 설치 과정을 간소화할 수 있는 인덕션 레인지용 히팅 모듈 및 포함하는 인덕션 레인지를 제공하는 것이다.It is an object of the present invention to provide a heating module for an induction range that has a simple structure and can simplify the installation process, and an induction range including the heating module.
상기한 본 발명의 목적을 달성하기 위하여, 본 발명의 일 측면에 따르면, 수지를 포함하는 재질의 코일 베이스; 및 길게 연장된 상태로 상기 코일 베이스에 일체화되고 전기 도선(electric wire)로 작용하는 복합소재 코일을 포함하며, 상기 복합소재 코일은 수지와 전기전도성 물질이 혼합된 복합소재이며, 상기 코일 베이스의 수지와 상기 복합소재 코일의 수지는 동종 또는 이종인, 인덕션 레인지용 히팅 모듈이 제공된다.In order to achieve the above object of the present invention, according to one aspect of the present invention, a coil base made of a material containing a resin; and a composite material coil integrated into the coil base in an extended state and acting as an electric wire, wherein the composite material coil is a composite material in which a resin and an electrically conductive material are mixed, and the resin of the coil base And the resin of the composite material coil is the same or different, a heating module for an induction range is provided.
상기한 본 발명의 목적을 달성하기 위하여, 본 발명의 다른 측면에 따르면, 상기 인덕션 레인지용 히팅 모듈을 포함하는 인덕션 레인지가 제공된다.In order to achieve the above object of the present invention, according to another aspect of the present invention, there is provided an induction range including a heating module for the induction range.
본 발명에 의하면 앞서서 기재한 본 발명의 목적을 모두 달성할 수 있다. 구체적으로, 첫째, 기존 인덕션 레인지용 유도 코일을 구리 대신 전기전도성 물질이 혼합된 수지재인 복합소재로 대체함으로써, 페라이트 코어의 별도 구성없이도 유도 가열 시 발생하는 고주파 노이즈를 제거할 수 있다.According to the present invention, all of the objects of the present invention described above can be achieved. Specifically, first, by replacing the existing induction coil for an induction range with a composite material that is a resin material mixed with an electrically conductive material instead of copper, high-frequency noise generated during induction heating can be removed without a separate configuration of the ferrite core.
둘째, 상술한 복합소재로 구성된 코일이 수지 재질로 형성되는 것에 착안하여, 유도 코일을 코일 베이스에 이중 사출 성형함으로써, 인덕션 레인지의 유도 코일의 설치 과정을 크게 간소화할 수 있다.Second, the installation process of the induction coil of the induction range can be greatly simplified by double injection molding the induction coil on the coil base, paying attention to the fact that the coil made of the above-described composite material is formed of a resin material.
셋째, 유도 코일이 코일 베이스에 일체화되어 형성됨으로써, 별도의 추가 구성없이 유도 코일을 고정함으로써, 유도 코일의 설치 과정은 물론 유지 과정에서의 유리함을 도모할 수 있다.Third, since the induction coil is formed integrally with the coil base, by fixing the induction coil without a separate additional configuration, it is possible to achieve advantages in the installation process of the induction coil as well as the maintenance process.
넷째, 구리 코일을 복합소재 코일로 대체함으로써, 전류의 주파수를 증가시킬 때 표면효과 및 노이즈가 증가하는 문제를 해결할 수 있으므로, 코일의 단면적을 크게 증가시킨 상태에서 인가되는 전류의 주파수를 높여 보다 나은 전열효과를 제공할 수 있다.Fourth, by replacing the copper coil with a composite coil, it is possible to solve the problem of increased surface effect and noise when increasing the frequency of the current, so it is better to increase the frequency of the applied current while greatly increasing the cross-sectional area of the coil. It can provide a heat transfer effect.

나아가, 본 발명의 일 실시예에 따른 복합소재 코일(110)의 횡단면은 매트릭스(111)의 높이 대비 폭의 크기가 더 크게 형성될 수 있다. 본 발명의 복합소재 코일은 기존 구리 재질의 유도 코일과 다르게 전열효과를 높이기 위하여 코일의 단면적을 증가시켜 나선형으로 감기는 회전 수(턴 수)를 축약시킴은 물론, 고주파 전류를 사용하여 전열효과를 높일 수 있다. 예를 들어, 복합소재 코일(110)의 단면적을 넓혀 기존 턴 수(감기는 회전 수)를 1/3정도로 축약시킨 상태에서 기존 30kHz의 전류를 100 ~ 120kHz의 고주파로 증가시켜 사용할 수 있다.Furthermore, the cross-section of the composite coil 110 according to an embodiment of the present invention may be formed to have a larger width compared to the height of the matrix 111 . The composite material coil of the present invention reduces the number of turns (number of turns) spirally wound by increasing the cross-sectional area of the coil in order to increase the heat transfer effect, unlike the existing copper induction coil, as well as improving the heat transfer effect using high-frequency current. can be raised For example, by increasing the cross-sectional area of the composite material coil 110 and reducing the number of turns (number of turns) by 1/3, the current of 30 kHz can be increased to a high frequency of 100 to 120 kHz.
이는, 기존의 인덕션 히터에 사용되던 구리 코일과 다르게 본 발명의 복합소재 코일은 탄소계열의 전기전도성 물질을 도전체로 사용함으로써, 코일의 단면적이 증가하고 전류의 주파수가 증가할 때 발생하던 표면 효과 및 노이즈 증가 문제를 해결할 수 있기 때문이다. 따라서, 상술한 바와 같이, 본 발명의 인덕션 레인지 히팅 모듈(100)은 코일의 단면적을 비약적으로 증가시킨 상태에서 전류의 주파수를 높여 보다 나은 전열효과를 제공할 수 있다. 덧붙여, 본 발명의 인덕션 레인지용 히팅 모듈은 기존 구리 코일의 문제점이던 고주파 노이즈를 제거하기 위하여, 전기도선을 복합소재로 구성하여 페라이트 코어의 부가 설치 구조를 생략하였으나, 필요에 따라 고주파 노이즈 제거 효율을 향상시키기 위하여 페라이트 코어를 더 설치할 수 있음은 물론이다. This is different from the copper coil used in the existing induction heater, the composite material coil of the present invention uses a carbon-based electrically conductive material as a conductor, so that the cross-sectional area of the coil increases and the surface effect that occurs when the frequency of the current increases and This is because it can solve the noise increase problem. Therefore, as described above, the induction range heating module 100 of the present invention can provide a better heat transfer effect by increasing the frequency of the current in a state in which the cross-sectional area of the coil is dramatically increased. In addition, the heating module for an induction range of the present invention omits the additional installation structure of the ferrite core by composing the electrical conductor with a composite material in order to remove the high-frequency noise, which is a problem with the existing copper coil, but the high-frequency noise removal efficiency is improved as necessary. Of course, it is possible to further install a ferrite core in order to improve it.
