본 고안은 통상의 전자보온 밥통의 전열장치에 있어서, 뚜껑과 밥통의 전기발열체를 각각 2개 1조로 징착하여 콘넥터에 조작으로 110V 및 220V의 사용 전원에 따라 각 발열체를 병렬로 접속하거나 직렬로 접속사용할 수 있게 하여 별도의 트랜스나 아답터의 부가 없이 110V 및 220V 전원에 겸용할 수 있는 전자 보온 밥통의 발열회로에 관한 것이다.The present invention is a heating device of a conventional electronic thermal insulation rice bowl, the electric heating elements of the lid and the rice bowl in each of the two sets of two by connecting each heating element in parallel or in series according to the power supply of 110V and 220V by operating to the connector The present invention relates to a heating circuit of an electronic thermal insulation rice bowl which can be used for 110V and 220V power supply without adding a transformer or an adapter.
종래의 전자보온 밥통의 전열장치는 뚜껑과 밥통에 소정의 저항치를 가진 전기발열체를 단일로 장착하여 110V전원으로만 사용할 수 있게 하였기 때문에 220V의 전원에서는 별도의 강압트랜스 없이는 사용할 수 없고 트랜스가 있다고 해도 사용할 때마다 트랜스를 연결조작해야 하는 불편한 결점이 있었다.The conventional heating device of the electric insulation rice bowl is equipped with a single electric heating element with a predetermined resistance value in the lid and the rice bowl to be used only as a 110V power source, so it cannot be used without a separate step-down transformer at a power source of 220V, even if there is a transformer. There was an inconvenient drawback of having to connect the transformer every time it was used.
본 고안은 이러한 결점을 시정하기 위하여 공지의 전자보온 밥통의 잔열장치에 있어서 직렬저항과 병렬 저항의 저항치가 각각 다르게 되는 점을 이용하여 뚜껑과 밥통에 적당한 저항치를 가진 2개 1조의 발열체를 각각 장착하여 밥통의 적당하 곳에 장착된 통상의 콘넥터를 사용전원에 따라 110V라고 표시된 일측으로 재치면 전원선에 대하여 각 발열체가 병렬로 접속되어 110V의 전원에서 알맞게 발열하여 보온할 수 있게 하고 콘넥터를 220V라고 표시된 타측으로 재치면 전원선에 대하여 각각 발열체가 직렬로 접속되어 200V의 전원에서 발열체가 적당한 저항치로 발열하여 별도의 트랜스와 아답터의 부가없이 110V 및 220V 전원에 보다 편리하게 겸용할 수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to install two sets of heating elements each having a proper resistance value in the lid and the rice bowl by using the fact that the resistance value of the series resistance and the parallel resistance are different in the residual heat storage device of the known thermal insulation rice bowl in order to correct such a defect. When the normal connector mounted on the proper place of rice bowl is placed on one side marked as 110V according to the power source, each heating element is connected in parallel to the power line so that it can heat properly and keep warm at 110V power source.The connector is called 220V. When it is placed on the other side, the heating elements are connected to the power line in series, so that the heating elements generate heat with proper resistance value at 200V power supply, so that they can be used more conveniently for 110V and 220V power supply without additional transformer and adapter. This will be described in detail with reference to the accompanying drawings.
도선(L1)(L2)간에 퓨즈선(F1), 전원램프(PL), 보온램프(WL), T.R.S(T), 저항(R1)(R2) 및 뚜껑용 발열체(CH1)와 밥통용 발열체(BH1)를 각각 병렬로 연결한 공지의 전자보온 밥통의 전열 회로에 있어서, 뚜껑용 발열체(CH1)와 밥통용 발열체(BH1)의 측방에 각각 발열체(CH2)(BH2)를 2개 1조가 되게 병설하여 통상의 콘넥터에 의하여 110V 및 220V의 사용전원에 따라 이들 발열체(CH1.2)(BH1.2)를 각각 직렬 또는 병렬로 접속할 수 있게 된 것이다. 이와 같이 된 본 고안은 사용전원에 따라 110V의 전원에서 사용할 경우, 도시되지 않은 콘넥터를 110V라고 표시된 일측으로 재치면 제2도에 표시된 바와 같이 각 발열체(BH2)(CH2)의 각 접속단자(A.C)(G.E)(B.F1)(D.F2)가 각각 접속되면서 전원 도선(L1.2)에 대하여 발열체(BH1.2)(CH1.2)가 각각 병렬로 접속되고 따라서 110V의 전원으로 발열체(BH1.2)(CH1.2)가 알맞게 발열되어 밥통을 전열로 보온하게 되며 또한 220V의 전원에서 사용할 경우에는 콘넥터를 220V라고 표시된 타측으로 재치면 제3도에 표시된 바와 같이 각 발열체(BH1.2)(CH1.2)의 일단부끼리 상호 연결되는 동시 이들의 접속단자(C.F1)(E.F2)가 각각 접속되면서 전원 도선(L1.2)에 대하여 각 발열체(BH1.2)(CH1.2)가 직렬로 접속되어 이들 발열체가 병렬연결시 보다 높은 저항치로서 220V의 전원에서 알맞게 발열하여 밥통을 보온하는 것으로, 공지의 전자보온밥통의 뚜껑용 발열체와 밥통용 발열체를 2개 1조로 병설하여 콘넥터의 조작으로 110V 및 220V의 사용 전원에 따라 각 발열체를 병렬접속 또는 직렬접속으로 하여 사용할 수 있게 하였기 때문에 종래의 단순한 110V 전용의 전자보온 밥통에 비하여 220V 전원에서도 별도의 트랜스나 아답터의 부가 없이 보다 편리하게 겸용할 수 있는 효과를 가진다.Fuse wire (F 1 ), power supply lamp (PL), insulation lamp (WL), TRS (T), resistor (R 1 ) (R 2 ) and lid heating element (CH 1 ) between conductors (L 1 ) (L 2 ) ), And a heating element of a well-known thermal insulation rice bowl in which a heating element (BH 1 ) for a bowl is connected in parallel, respectively, the heating element (CH 2 ) on the side of the heating element for a lid (CH 1 ) and the heating element (BH 1 ) for a lid. (BH 2) two of these heating elements depending on the power of 110V and 220V, by an ordinary connector in juxtaposition to be 1 Joe is a (CH 1. 2) (BH 1. 2) to allow access respectively in series or in parallel . The present invention, when used in the power supply of 110V according to the power source, when connecting the connector (not shown) to one side marked 110V as shown in Figure 2 , each connection terminal of each heating element (BH 2 ) (CH 2 ) (AC) (GE) (BF 1) (DF 2) the heat generating element with respect to the electrical conductors (L 1. 2) while connecting each of (BH 1. 2) (CH 1. 2) , each connected in parallel Therefore, the 110V a power heating element (BH 1. 2) (CH 1. 2) the heat is and to warm the rice cooker to heat moderately as also when used in a power supply of 220V, the tooth material take the connector labeled 220V side shown in FIG. 3 each heating element (BH 1. 2) (CH 1. 2) of one end the same time their connection terminal are interconnected to each other (CF 1) (EF 2), each heating element with respect to the electrical conductors (L 1. 2) as respectively connected (BH 1. 2) (CH 1. 2) is connected in series with the power of 220V these heat generating element as a high resistance value than that of the parallel connection Insulate the rice bowl by heating properly, and connect the heating element for the lid and the heating element for the rice bowl in a pair of two together. Since it can be used as compared to the conventional simple 110V dedicated electronic rice cooker has the effect that can be used more conveniently even without the addition of a separate transformer or adapter even at 220V power supply.
