본 고안은 전자렌지의 스터러 휀 회전축에 관한 것으로 회전축의 구조를 2단으로 개선하여, 내부 전자파가 회전축을 통해 외부로 누설되는 것을 방지할 수 있도록된 전자렌지의 스터러 휀 회전축에 관한 것이다.The present invention relates to a stirrer fan rotating shaft of a microwave oven and improves the structure of the rotary shaft in two stages, and relates to a stirrer fan rotating shaft of a microwave oven which can prevent internal electromagnetic waves from leaking to the outside through the rotary shaft.
종래 전자렌지 내부에는 스터러 휀(1)이 설치되어 있어서, 전자파분산 및 열풍순환작용을 하는데, 이때 히터(12)에서 발생되는 고온으로 인하여 모터(6)는 스터러 휀(1)을 고정시킨 회전축(2)상에 직접 설치하지 못하고 일측으로 설치하여, 회전축(2)에 고정시킨 풀리(5)외 벨트(7) 연결되어 스트러 휀(1)을 회전시키는데 이때 상기 회전축(2)은 히터(12)에서 발생되는 고온에 의해 변형되는 것을 방지하기 위해 스테인레스 등 금속재 계통으로된 일체형의 회전축(2)을 사용하므로 이회전축(2)이 안테나 역활을 하게 되어 내부 전자파가 회전축(2)을 따라 전자렌지 몸체(14)외부로 누설되는 결점이 있었다.In the conventional microwave oven, a stirrer 휀 1 is installed to perform electromagnetic wave dispersion and hot air circulation. At this time, the motor 6 fixes the stirrer 1 1 due to the high temperature generated by the heater 12. It is not installed directly on the rotating shaft (2), it is installed on one side, and the pulley (5) and the belt (7) connected to the rotating shaft (2) are connected to rotate the strut (1), wherein the rotating shaft (2) is a heater In order to prevent deformation due to the high temperature generated in (12), since the integrated rotary shaft 2 of a metal system such as stainless steel is used, the two rotary shafts 2 serve as antennas, and the internal electromagnetic waves along the rotary shafts 2 are used. There was a flaw leaking out of the microwave oven body 14.
따라서, 본고안은 상기와 같은 결점을 해소시키기 위해서 2단으로된 회전축을 구성하되 전자렌지 몸체 내부로 들어가는 하부축은 내열성이 강한 비전도성 재질로 구성하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, this proposal constitutes a two-stage rotating shaft to solve the above drawbacks, but the lower shaft entering the inside of the microwave oven is composed of heat-resistant non-conductive material. The effect will be described in detail as follows.
전자렌지의 스터러 휀(1)을 회전시키는 회전축(2)에 있어서, 회전축(2)을 상부축(2a)과 하부축(2b) 2단으로 구성하되 상부축(2a)에는 나사홈(3)이, 하부축(2b)에는 나선부(4), (4')가 각각 형성되어 분해 조립이 가능하도록 하는 한편, 상부축(2a)은 금속재질로 하부축(2b)은 금속재가 아닌 내열성이 강한 비전도성 재질로 각각 구성하여 전자렌지 내부전자파가 회전축(2)을 통해 누설되는 것을 방지할 수 있도록된 것이다.In the rotary shaft (2) for rotating the stirrer (1) of the microwave oven, the rotary shaft (2) consists of two stages of the upper shaft (2 a ) and the lower shaft (2 b ), but the screw on the upper shaft (2 a ) The groove 3 has a spiral portion 4, 4 'formed in the lower shaft 2 b to allow disassembly and assembly, while the upper shaft 2 a is made of metal and has a lower shaft 2 b. ) Is made of a non-conductive material, each of which is not heat-resistant, but a metal, so as to prevent the microwaves from leaking through the rotating shaft 2.
미설명 부호 5는 풀리이고, 6은 모터, 7은 벨트, 8은 호울더, 9는 베어링, 10은 고정핀, 11은 와셔, 12는 히터, 13은 너트, 14는 몸체 인것이다.5 is a pulley, 6 is a motor, 7 is a belt, 8 is a holder, 9 is a bearing, 10 is a fixing pin, 11 is washer, 12 is a heater, 13 is a nut, and 14 is a body.
이와같이 구성된 본고안의 작용효과를 설명하면 다음과 같다.The operational effects of the proposed paper thus constructed are as follows.
도시된 도면 제2도에서와 같이 상부축(2a)과 하부축(2b)이 나합된 회전축(2)에 풀리(5), 베어링(9), 스터러 휀(1)등을 각각의 위치에 고정시킨 다음 벨트(7)를 이용하여 풀리(5)와 모터(6)를 연결시키게 되면 상부축(2a)에 고정된 풀리(5)가 회전하게 되며 이때 상부축(2a)의 나사홈(3)에 하부축(2b)의 나선부(4)가 상호 나합되어 있으므로 상부축(2a)과 하부축(2b)이 동시 회전이 이루어져 하부축(2b)에 고정된 스터러 휀(1)이 회전되면서, 히터(12)에서 발생된 고열과 내부 전파를 조리실(도시되지 않음)하부로 이동시켜 음식물을 가열하게 된다.As shown in FIG. 2, the pulley 5, the bearing 9, the stirrer 휀 1, and the like are respectively attached to the rotating shaft 2 where the upper shaft 2 a and the lower shaft 2 b are combined. using the following belt 7 was fixed to the position of the pulley (5) and when tied to a motor 6, a pulley (5) fixed on the minor axis (2 a) is rotated wherein the minor axis (2 a) Since the screw portions 3 of the lower shaft 2 b are screwed together to the screw groove 3, the upper shaft 2 a and the lower shaft 2 b are simultaneously rotated to be fixed to the lower shaft 2 b . As the stirrer 휀 1 is rotated, the high heat and internal radio waves generated by the heater 12 are moved to the lower portion of the cooking chamber (not shown) to heat the food.
이때 전자렌지 내부에서 분산되는 전자파는 전도성 재질을 통해 전자렌지 몸체(14)외부로 이탈하려는 성질을 가지고 있기 때문에 본고안은 이와같은 전자파의 성질을 이용하여 회전축(2)을 상부축(2a)과 하부축(2b)으로 분리 구성하되, 전자렌지 몸체(14)내부로 들어가는 하부축(2b)은 내열성이 강한 비전도성 재질로 구성하여 내부 전자파가 회전축(2)을 따라 전자렌지 외부로 누설되는 것을 차단시키는 것으로서 종래의 스테인레스등 금속재의 일체형 회전축(2)의 결함요인이었던 회전축(2)의 안테나 역할로 인하여 내부전자파가 외부로 누설되는등 취약점을 해소시킨 것으로 즉 회전축(2)의 하부축(2b)을 내열성이 강한 비전도성 재질로 만들어줌으로써 전자렌지의 내부 전자파가 외부로 누설되는 것을 방지하여 제품의 신뢰성 및 품질향상을 꾀할 수 있도록 된 것이다.In this case, since the electromagnetic waves dispersed in the microwave oven have a property of leaving the microwave oven body 14 through a conductive material, the present invention uses the characteristics of the electromagnetic wave to rotate the rotary shaft 2 and the upper shaft 2a. The lower shaft 2b is separated into the lower shaft 2b, but the lower shaft 2b, which enters the inside of the microwave oven body 14, is made of a non-conductive material having a high heat resistance, so that internal electromagnetic waves leak out of the microwave oven along the rotating shaft 2. By blocking the internal weakness of the external shaft due to the role of the antenna of the rotating shaft (2), which was a defect of the integrated rotating shaft (2) of the conventional metal such as stainless steel, that is, the lower shaft (2b) of the rotating shaft (2) ) Is made of heat-resistant non-conductive material to prevent leakage of the internal electromagnetic waves of the microwave oven to the outside to improve the reliability and quality of the product. It is.
