It relates to a circulator.
종래의 경우에는 첨부된 도면 제4도와 같이 컨벡션 기능을 갖는 전자렌지의 경우 열풍순환팬(21)의 둘레에 설치된 히터(22)의 열을 열풍순환팬(21)이 조리실(23)내로 열풍을 불어주는 구조로 되어 있으나 이 경우에는 열을 불어주는 열 순환 장치가 복잡하고 열풍효과가 떨어지는 결점이 있었을 뿐 아니라 히터의 주변에 단열처리를 철저히 해야 하는 등의 비 경제적인 결점이 있었다.In the related art, in the case of the microwave oven having the convection function as illustrated in FIG. 4, the hot air circulation fan 21 heats the hot air into the cooking chamber 23 through the heat of the heater 22 installed around the hot air circulation fan 21. In this case, there is a drawback that the heat circulation device for blowing heat is complicated and the hot air effect is poor, and there is an uneconomical defect such as thorough insulation treatment around the heater.
이에 본 발명은 팬모터의 열풍순환팬 자체내부에 운모판에 방열선이 감겨 형성된 평면히터를 내장시켜 팬모터 회전 시 조리실 내부로 열풍을 불어주어 열풍효율을 높일 수 있도록 안출된 것으로 첨부된 도면에 의거하여 구성 및 작용효과를 설명하면 다음과 같다.Accordingly, the present invention has a planar heater formed by winding a heat radiation wire on the mica plate inside the hot wind circulation fan itself of the fan motor to blow hot air into the cooking chamber when the fan motor rotates to increase the hot air efficiency. Based on the configuration and the effect of operation as follows.
컨벡션 기능을 갖는 전자렌지에 있어서, 팬모터(1)의 열풍순환팬(2) 자체에 운모판(3a)상에 방열판(3b)이 감겨 형성된 평면히터(3)를 내장시킬 수 있고, 상기 평면히터(3)의 배선은 모터축(4)을 따라 회전하면서 전원을 공급하는 슬립링(5)에 각각 연결시키고, 상기 슬립링(5)에는 전원을 연결시키는 브러쉬(6)를 연결토록 설치하여 구성된 것으로, 미 설명부호 7은 조리실이다.In a microwave oven having a convection function, the hot air circulation fan 2 itself of the fan motor 1 may incorporate a flat heater 3 formed by winding a heat sink 3b on a mica plate 3a. The wiring of the heater 3 is connected to each of the slip rings 5 for supplying power while rotating along the motor shaft 4, and the brushes 6 for connecting the power are connected to the slip rings 5. In the description, reference numeral 7 denotes a cooking chamber.
이와 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
팬모터(1)의 열풍순환팬(2) 자체에 운모판(3a)상에 발열선(3b)이 감겨 형성된 평면히터(3)를 내장시키고,Into the hot air circulation fan (2) of the fan motor (1) is built a flat heater (3) formed by winding the heating wire (3b) wound on the mica plate (3a),
상기 평면히터(3)의 발열선(3b) 배선을 모터축(4) 내부를 따라 회전하면서 전원을 공급하는 슬립링(5)에 각각 연결시키고,The heating wire 3b of the planar heater 3 is connected to a slip ring 5 for supplying power while rotating along the inside of the motor shaft 4,
상기 슬립링(5)은 브러쉬(6)를 통해 전원과 연결토록 설치된 상태에서 컨벡션형 전자렌지에 전원인가 시키면 전원이 브러쉬(6)를 통해 슬립링(5)으로 전원이 인가되어 회전하는 모터축(4) 내부에 설치된 배선을 통해서 운모판(3a)에 감겨진 발열선(3b)으로 전원이 인가되면 열풍순환팬(2)에 내장된 평면히터(3)가 가열되어 평면히터(3)의 열이 즉시 열풍순환팬(2)에 전달되면, 이때 팬모터(1)의 구동력에 의해 열풍순환팬(2)이 회전되면서 평면히터(3)의 열을 열풍순환팬(2)의 회전으로 전자렌지 조리실 (7)에 열풍을 불어주는 컨벡션형 전자렌지의 열 순환장치에 관한 것이다.When the slip ring 5 is applied to the convection type microwave oven in a state in which it is installed to be connected to the power through the brush 6, the power is applied to the slip ring 5 through the brush 6 to rotate the motor shaft. (4) When power is applied to the heating wire 3b wound on the mica plate 3a through the wiring provided therein, the flat heater 3 embedded in the hot air circulation fan 2 is heated to heat the flat heater 3. When this is immediately transmitted to the hot wind circulation fan (2), the hot wind circulation fan (2) is rotated by the driving force of the fan motor (1) while the heat of the flat heater (3) by the rotation of the hot air circulation fan (2) The heat circulation apparatus of the convection type microwave oven which blows hot air into the cooking chamber (7).
따라서, 본 발명은 팬모터(1)의 구동력에 의해 회전되는 열풍순환팬(2)자체에 평면히터(3)를 내장시켜 열을 발열시키는 평면히터(3)의 열을 열풍순환팬(2)의 회전으로 직접 열풍을 조리실 내부로 불어줌으로써 열의 고효율을 얻을 수 있고, 평면히터의 설치구조가 간단하여 작업공정을 향상시킬 수 있는 등의 효과를 얻을 수 있다.Therefore, the present invention is a hot air circulation fan (2) to heat the heat of the plane heater (3) that generates heat by embedding the plane heater (3) in the hot air circulation fan (2) itself is rotated by the driving force of the fan motor (1) The high efficiency of heat can be obtained by directly blowing the hot air into the cooking chamber by the rotation of, and the installation structure of the flat heater is simple, so that the working process can be improved.
