본 고안은 전자레인지의 노이즈 필터회로 기판고정 장치에 관한 것으로, 특히 외부로부터 공급되는 입력전원에 포함되어 있는 노이즈를 제거하기 위하여 기기의 입력전원공급단에 설치되는 노이즈필터회로 기판을 기기의 전장품에 영향을 받지않는 위치에 간단용이하게 설치고정 및 분리를 할 수 있도록 한 전자레인지의 노이즈필터회로 기판고정 장치에 관한 것이다.The present invention relates to a noise filter circuit board fixing device of a microwave oven, and in particular, to remove noise contained in an input power source supplied from the outside, a noise filter circuit board installed at an input power supply terminal of a device is applied to an electronic device. The present invention relates to a noise filter circuit board fixing device for a microwave oven that can be easily installed and detached in an unaffected position.

종래의 전자레인지에서 노이즈필터회로 기판은 전자레인지의 후방송풍팬이 설치되는 그 주변에 케이스이 저판상에 고정설치 되어 있는 관계로 기기의 구동시 전장품에서 발생되는 발열로 인해 노이즈필터회로 소자에 악영향을 주게 되는가 하면, 상기 노이즈필터회로 기판은 나사와 같은 별도의 부품으로 고정설치 하도록 되어 있어 고정설치나 수리작업시 번거로움을 주기 때문에 작업능률을 저하시킴은 물론 별도의 부품사용에 따른 기기의 원가를 상승시키게 되는 문제점을 가지고 있었다.In a conventional microwave oven, the noise filter circuit board has a bad effect on the noise filter circuit element due to the heat generated from the electrical equipment when the device is driven, since the case is fixed on the bottom plate around the microwave broadcasting fan of the microwave oven. In addition, since the noise filter circuit board is fixedly installed as a separate component such as a screw, it is cumbersome during fixed installation or repair work, thereby reducing the work efficiency and cost of the device according to the use of separate components. Had the problem raised.

본 고안은 상기와 같은 문제점을 해결하기 위하여 전자레인지의 내부에 소정의 형상으로 절곡된 캐비티의 상판에 탄성괘지구와 결합공을 형성시켜 이에 노이즈 필터회로 기판을 삽입함으로써, 전장품에 영향을 받지 않는 위치에서 고정설치 및 분리되도록 하여 고정설치작업 및 수리시 분리 교체작업을 간단용이하게 할 수 있도록 한 것이다.The present invention is to solve the above problems by forming the elastic ruler and the coupling hole in the upper plate of the cavity bent in a predetermined shape inside the microwave oven by inserting the noise filter circuit board, thereby not affected by the electrical equipment Fixed installation and separation at the position to make it easy to separate and replace the fixed installation work and repair.

이하 첨부된 도면에 의거 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도 및 제 2 도에 도시한 바와같이, 전자레인지의 내부에 소정형상으로 절곡형성된 캐비티의 상판(1), 상부에 노이즈필터회로기판(2)을 고정설치시키되, 상기 노이즈필터회로기판(2)의 일측단부에는 한쌍의 삽입돌기(3)을 형성시키고, 상기 노이즈필터회로기판(2)이 고정설치되는 상기 캐비티의 상판(1) 절곡부위에는 한쌍의 삽입공(4)을 천설시키며, 상기 캐비티의 상판(1)의 타측에는 그 상판(1)의 일부를 절결하여 상방으로 수직 입설시킨 상단에 슬라이딩부(5)를 가진 한쌍의 탄성괘지부(6)를 일체로 형성시켜서 된 것이다.As shown in FIGS. 1 and 2, an upper plate 1 of a cavity bent to a predetermined shape inside the microwave oven and a noise filter circuit board 2 are fixedly installed thereon, and the noise filter circuit board ( A pair of insertion protrusions 3 are formed at one end of 2), and a pair of insertion holes 4 are laid at the bent portion of the upper plate 1 of the cavity in which the noise filter circuit board 2 is fixed. The other side of the upper plate (1) of the cavity is formed by integrally forming a pair of elastic ruler (6) having a sliding portion (5) on the upper end of the upper plate (1) is cut vertically vertically placed.

상기와 같이 구성시켜서된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention configured as described above.

먼저 전자레인지의 내부 캐비티의 상판(1)에 형성된 한쌍의 삽입공(4)과 수직입설된 슬라이딩부(5)를 가진 노이즈필터회로 기판(2)을 삽입고정시키되, 상기 노이즈필터회로기판(2)의 삽입돌기(3)가 상기 캐비티의 상판(1)의 삽입공(4)에 먼저 삽입시키고, 이어서 상기 노이즈필터회로기판(2)의 타측을 하방으로 눌러주게되면 상기 노이즈필터회로기판(2)의 타측은 상기 수직입설된 상단에 슬라이딩부(5)를 가진 탄성괘지부(6)가 일측방으로 벌어지면서 상기 노이즈필터회로 기판(2)의 타측이 상기 슬라이딩부(5)를 미끄러져 내려가 탄성괘지부(6)에 괘지되어 제 2 도에 도시한 바와같이 고정설치되는 것이다.First, the noise filter circuit board 2 having a pair of insertion holes 4 formed in the upper plate 1 of the inner cavity of the microwave oven and a sliding part 5 vertically inserted therein is fixed, and the noise filter circuit board 2 Is inserted into the insertion hole 4 of the upper plate 1 of the cavity, and then the other side of the noise filter circuit board 2 is pressed downward. The other side of the) is the elastic rubbing portion (6) having a sliding portion (5) on the vertically placed top spreads to one side while the other side of the noise filter circuit board (2) is sliding down the sliding portion (5) It is hung on the elastic ruled portion 6 is fixedly installed as shown in FIG.

상기와 같이 고정설치된 상태에서 노이즈필터회로기판(2)을 분리하고져 할 경우, 상기 캐비티의 상판(1)에 형성된 탄성괘지부(6)의 상단 슬라이딩부(5)를 일측방으로 밀어준후, 상기 노이즈필터회로기판(2)을 상방으로 잡아당기면 상기 노이즈필터회로기판(2)의 타측은 상기 탄성괘지부(6)로 벗어나고, 상기 캐비티의 상판(1)의 한쌍에 삽입공(4)에 삽입된 노이즈필터회로기판(2)의 삽입돌기(3)가 빠져나오게 되므로 캐비티의 상판(1)으로부터 노이즈필터회로기판(2)을 분리할 수 있게 되는 것이다.When the noise filter circuit board 2 is to be separated in the fixed installation state as described above, the upper sliding part 5 of the elastic hanging part 6 formed on the upper plate 1 of the cavity is pushed to one side, and then When the noise filter circuit board 2 is pulled upward, the other side of the noise filter circuit board 2 is released to the elastic stop portion 6 and inserted into the insertion hole 4 in a pair of the upper plate 1 of the cavity. Since the insertion protrusion 3 of the noise filter circuit board 2 is released, the noise filter circuit board 2 can be separated from the upper plate 1 of the cavity.

이상에서 설명한 바와같이, 본 고안은 노이즈필터회로 기판을 전자레인지의 내부에 설치된 캐비티의 상판 상부에 고정설치함으로써 구동시 전자레인지의 전장품에서 발생되는 발열로부터 노이즈필터회로 기판의 회로소자에 악영향이 미치는 것을 방지할 수 있어 기기의 수명을 길게 연장시킬 수 있고, 또한 캐비티의 상판 상부에 고정설치되는 노이즈필터회로기판은 캐비티의 상판과 일체로 형성된 탄성괘지구와 삽입공으로 간단용이하게 고정설치되도록 함으로써 조립작업이 능률향상은 물론 별도의 나사와 같은 고정부품을 사용하지 않아도 되어 그만큼 부품의 수를 줄일 수 있는 경제적인 효과 또한 제공할 수 있게 되는 것이다.As described above, the present invention fixedly installs the noise filter circuit board on the upper plate of the cavity installed inside the microwave oven, thereby adversely affecting the circuit elements of the noise filter circuit board from the heat generated from the electronic parts of the microwave oven during operation. It can be prevented from prolonging the life of the device, and the noise filter circuit board fixedly installed on the upper plate of the cavity can be easily fixed and installed by the elastic ruler and insertion hole formed integrally with the upper plate of the cavity. Not only does the work improve efficiency, but it also eliminates the need for a separate component such as a screw, thereby providing an economical effect that reduces the number of parts.
