본 발명은 전자렌지용 냉각팬 가이드 구조에 관한 것으로서 특히, 냉각팬 가이드의 양측으로 지지벽을 사출 성형한 후 전장품을 설치함으로써 전자렌지의 적은 공간을 최대한으로 이용할 수 있도록 한 발명에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling fan guide structure for a microwave oven, and more particularly, to an invention in which a small space of a microwave oven can be utilized to the maximum by installing electrical components after injection molding the supporting walls on both sides of the cooling fan guide.

일반적으로 전자렌지의 일측 전장실에는 마그네트론, 고압트랜스, 냉각팬 등의 각종 기기들이 구비되어 전자렌지 고유의 기능을 통제하도록 구성한 것인데, 주로 캐비티 본체의 일측벽에 설치된 마그네트론에서 고주파를 발진하여 조리실 내부로 조사(照射)토록 함으로써 조리실 내부에서 조리가 이루어지도록 구성한다.In general, one side of a microwave oven is equipped with various devices such as magnetron, high voltage transformer, and cooling fan to control the unique functions of the microwave oven.It mainly oscillates a high frequency from the magnetron installed at one side wall of the cavity main body, It is configured to cook inside the cooking chamber by irradiating with a furnace.

상기 마그네트론은 전장실의 바닥면에 설치된 고압트랜스에서 고압의 전류를 안정적으로 인가받아 고주파를 발진하게 되는데 이때 마그네트론에서는 상당한 양의 열이 발생된다.The magnetron is stably applied with a high voltage current in a high voltage transformer installed on the bottom of the electric room to oscillate a high frequency, at which time a considerable amount of heat is generated in the magnetron.

물론 마그네트론으로 고압의 전류를 인가토록 하는 고압트랜스에서도 철심에 권회된 1차코일과 2차코일이 상호 유도작용하여 고압의 전류를 유도 증폭할 때 상당한 열이 발생된다.Of course, even in a high-voltage transformer that applies a high-voltage current to the magnetron, a significant amount of heat is generated when the primary coil and the secondary coil wound on the iron core mutually induce and amplify the high-voltage current.

따라서 상기한 마그네트론과 고압트랜스에서 발생되는 열을 효과적으로 식혀줄 수 있는 별도의 장치가 필요하게 되는데 주로 전장실 후면에 모터로 구동되는 냉각팬을 설치하여 상기 마그네트론과 고압트랜스를 냉각시키도록 구성되어 있다.Therefore, a separate device capable of effectively cooling the heat generated from the magnetron and the high-voltage transformer is required. The motorron is installed in the rear of the electrical equipment room to cool the magnetron and the high-voltage transformer. .

그런데 종래에는 제3도에서 예시한 바와 같이 냉각팬 가이드가 없이 모터가 설치된 냉각팬(4) 만을 전장실 후면에 취부시키기 위하여 후면판넬(1)을 내측으로 포밍시킨 고정부(2)가 형성되고 그 고정부(2)에 팬모터(3)를 체결하여 왔는데 이는 냉각팬(4)이 회전시에 소음이 발생되고 회전력에 의한 진동이 발생되어 체결부위가 느슨해지는 결점이 있었다.However, in the related art, as illustrated in FIG. 3, a fixing part 2 having a rear panel 1 formed therein is formed in order to mount only the cooling fan 4 on which the motor is installed without the cooling fan guide on the rear side of the battlefield. The fan motor 3 has been fastened to the fixing part 2, which has a drawback in that noise is generated when the cooling fan 4 is rotated and vibration is generated by the rotational force, thereby loosening the fastening part.

그래서 이것을 좀더 보온하기 위해서 제4도에서 예시한 바와 같이 냉각팬(4)에 가이드(5)를 형성하여 전장실에 취부시켰는데 이 구조도 소음과 진동은 예방할 수 있으나 전자렌지의 전장실에는 냉각팬(4) 뿐만 아니라 각종 부품을 설치하는 것이기 때문에 냉각팬 가이드(5)의 설치에 따라 더욱더 전장실이 좁아지는 문제점이 있는 것이다.Therefore, in order to insulate this further, as illustrated in FIG. 4, a guide 5 was formed in the cooling fan 4 and mounted in the electrical compartment. In this structure, noise and vibration can be prevented, but cooling is performed in the electrical compartment of the microwave oven. Since not only the fan 4 but also various components are installed, there is a problem in that the electrical chamber becomes narrower according to the installation of the cooling fan guide 5.

따라서 본 발명의 목적은 상기한 종래의 결점을 해소하고자 냉각팬 가이드의 배면에 홈부를 형성하여 전장부품을 취부할 수 있도록 하는 전자렌지 냉각팬 가이드 조립구조를 제공하는데 있다.Accordingly, an object of the present invention is to provide a microwave cooling fan guide assembly structure in which a groove is formed on a rear surface of a cooling fan guide to mount electrical components in order to solve the above-described drawbacks.

이하 본 발명의 상세한 기술구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, detailed technical configurations and operational effects of the present invention will be described in detail with reference to the accompanying drawings.

냉각팬(10)을 가이드 본체(20)에 취부함에 있어서 가이드 본체(20)의 양측에는 지지벽(30a)(30b)을 절첩식으로 연설하고 그 일측 지지벽(30a)의 배면에는 홈부(40)를 형성하여 라인필터 등의 전장부품(41)을 설치할 수 있게하며, 상기한 지지벽(30a)(30b)의 상하단에는 걸림구(31)를 형성하여 가이드 본체(20)의 브라켓(21)에 천공한 걸림공(22) 걸려 절첩되게 구성되어 있다.In attaching the cooling fan 10 to the guide main body 20, the supporting walls 30a and 30b are folded on both sides of the guide main body 20, and the groove 40 is provided on the rear surface of the one side of the supporting wall 30a. ) To install electrical components 41, such as a line filter, and the upper and lower ends of the support walls (30a, 30b) to form a locking hole 31 to the bracket 21 of the guide body 20 The engaging hole 22 punched in is caught and folded.

이와 같이 구성된 본 발명은 전자렌지의 종류에 따라서 접거나 펴서 전상실에 설치할 수가 있는 것인데 우선 펴서 설치할 때에는 가이드 본체(20)에 절첩식으로 연결된 지지벽(30a)(30b)을 일자로 편 다음 그 일측의 지지벽(30a)의 배면에 형성된 홈부(40)에 라인필터 등 전장부품(41)을 집어넣고 전자렌지의 전장실에 설치하는 것이다.According to the present invention configured as described above, it is possible to fold or unfold according to the type of microwave oven to be installed in the pre-chamber. The electrical components 41, such as a line filter, are put into the groove part 40 formed in the back surface of the support wall 30a of one side, and it installs in the electrical chamber of a microwave oven.

또한 접어서 설치할 때에는 우선 가이드 본체(20)에 절첩식으로 사출 성형된 지지벽(30a)(30b)을 일자로 편 다음 일측 지지벽(30a)의 배면에 형성된 홈부(40) 속에 필요에 따른 전장부품(41)을 먼저 설치하는 것이며, 그후 지지벽(30a)(30b)을 접으면 지지벽(30a)(30b)의 상하단에 형성된 걸림구(31)가 가이드 본체(20)의 브라켓(21)에 천공된 걸림공(22)에 끼워지면서 지지벽(30a)(30b)이 가이드 본체(20)에 견고하게 고정이 되는 것이다.In addition, when folding and installing, first, the support walls 30a and 30b which are injection-molded in the guide main body 20 are straightened, and then the electric parts as necessary in the grooves 40 formed on the rear surface of the one support wall 30a. (41) is installed first, and then, when the support walls (30a) and (30b) are folded, the catches (31) formed at the upper and lower ends of the support walls (30a) and (30b) are attached to the brackets (21) of the guide body (20). The support walls 30a and 30b are firmly fixed to the guide body 20 while being fitted into the perforated engaging holes 22.

이와 같이 본 발명은 조립식인 것인 특징이고 특히, 일측 지지벽(30a)의 배면에 홈부(40)를 형성하여 전장부품(41)을 설치하는 것이므로 전자렌지 전장실의 적은 공간을 최대한으로 활용할 수가 있는 것이다.As described above, the present invention is characterized in that it is prefabricated, and in particular, the groove 40 is formed on the rear surface of the one side support wall 30a to install the electric component 41 so that the small space of the microwave electric equipment room can be utilized to the maximum. It is.

또한 본 발명은 가이드 본체(20)와 지지벽(30a)(30b)과의 연접부위가 형으로 형성되었기 때문에 지지벽(30a)(30b)를 접었을 때 가이드 본체(20)와 지지벽(30a)(30b) 사이가 틈새가 없이 원활히 접어지는 것이다.In addition, in the present invention, since the joint portion between the guide body 20 and the support walls 30a and 30b is formed in a shape, when the support walls 30a and 30b are folded, the guide body 20 and the support wall 30a are folded. There is no gap between 30b and it is a smooth folding.

이와같이 상술한 본 발명은 가이드 본체의 양측에 절첩식으로 형성된 지지벽을 사출 성형하여 전자렌지의 종류에 따라 접었다 폈다 할 수 있게 하였으며, 일측 지지벽의 홈부에는 전자부품을 설치하도록 하여 전자렌지 전장실의 좁은 공간을 최대한으로 활용할 수 있는 매우 유용한 발명인 것이다.As described above, the present invention allows injection and folding of support walls formed on both sides of the guide body to be folded and unfolded according to the types of microwave ovens. It is a very useful invention that can take full advantage of the narrow space.
