본 고안은 송풍팬으로부터 흡입되는 냉각공기를 안내하는 안내판에 관한 것으로, 특히 냉각덕트의 흡입구 상측에 설치하여 고압트랜스포머에서 나오는 자기력이 마그네트론에 미치는 것을 차단하며 송풍팬에 의해 흡입되는 외부의 냉각공기를 적절히 덕트내로 유입되게 한 냉각공기흡입안내판에 관한 것이다.The present invention relates to a guide plate for guiding cooling air sucked from a blower fan, and in particular, installed above the inlet of a cooling duct to block magnetic force from the high-voltage transformer on the magnetron, and to allow external cooling air to be sucked by the blower fan. It relates to a cooling air suction guide plate that is properly introduced into the duct.

일반적으로 전자렌지의 내부 일측에는 일련의 냉각시스템이 구비되는바, 이 냉각 시스템에서 냉각효율을 높이기 위해 냉각덕트가 설치되며 이 냉각덕트는 하단에 지지판(1)을 갖는 지지패널(2)이 전자렌지의 바닥판(3)상에 입설되고, 이 지지패널(2)의 배면에 고정되는 팬모터(4)와, 이 전방에 송풍팬(5)이 설치되며 이 송풍팬(5)으로부터 통로(6)를 형성하되, 상부에서 양측으로 분지되게 주통로(7)와 보조통로(8)를 개설하여 주통로(7) 전방에는 일측에 고정홈(10)을 갖는 유입안내통로(9)를 형성하며 상기 보조통로(8)는 상측으로 연장하여 유로(11)를 개설하고, 이 유로(11) 상부는 전면이 개방되는 개방부(12)를 갖게 형성되어 있다.In general, one side of the microwave oven is provided with a series of cooling system, the cooling duct is installed to increase the cooling efficiency in the cooling system, the cooling duct is a support panel (2) having a support plate (1) at the bottom of the electronic A fan motor 4 installed on the bottom plate 3 of the stove and fixed to the rear surface of the support panel 2, and a blowing fan 5 in front of the stove, is provided with a passage (from the blowing fan 5). 6) to form the main passage (7) and the auxiliary passage (8) to be branched from both sides from the top to form the inlet guide passage (9) having a fixed groove (10) on one side in front of the main passage (7) The auxiliary passage 8 extends upward to open the passage 11, and the upper passage 11 is formed to have an open portion 12 in which the front surface is opened.

이와 같이 구성된 냉각덕트는 송풍팬(5)의 작동에 의해 외부의 공기를 덕트내로 흡입하여 흡입된 공기의 일부는 주통로(7)로 유도되어 마그네트론(13)을 냉각하고 이를 거친 냉각공기는 다시 조리실 내부로 유입되어 고열상태인 조리실내부를 냉각하게 된다. 또한 외부의 흡입공기중 다른 지류는 보조통로(8)로 유도되어 상시의 개방부(12)를 통해 마그네트론의 발진부가 설치된 상판과 캐비넷 사이의 가열된 공기를 냉각시키는 작용을 하게 된다.The cooling duct configured as described above sucks the outside air into the duct by the operation of the blower fan 5, and a part of the sucked air is led to the main passage 7 to cool the magnetron 13, and the cooled cooling air again It is introduced into the cooking chamber to cool the inside of the cooking chamber in a high temperature state. In addition, the other branch of the external suction air is led to the auxiliary passage (8) to act to cool the heated air between the cabinet and the upper plate is installed the oscillation portion of the magnetron through the constant opening (12).

그러나 상술한 바와 같이 송풍팬(5)에 의해 외부공기를 유입할 시 외부공기가 흡입구내로 적절히 흡입되게 할 유도 또는 안내판이 마련되어 있지 않으므로 송풍팬의 흡입력에 비해 실제 흡입 유도되는 외부공기는 미미한 정도에 불과한 실정이며 마그네트론 하부에 설치된 고압트랜스포머가 방출하는 자기력을 차폐할 장치가 미비되어 상기 마그네트론이 손상될 우려가 발생하는 등의 제반문제가 있어 왔다.However, as described above, when the inlet air is introduced by the blower fan 5, there is no induction or guide plate to allow the inlet air to be properly sucked into the intake port. There have been various problems such as the possibility of damaging the magnetron due to the lack of a device for shielding the magnetic force emitted by the high-voltage transformer installed under the magnetron.

본 고안은 전술한 바와 같은 제반문제를 해소하기 위해 안출한 것으로 냉각덕트의 흡입구 상측에 설치되며 외부공기의 흡입을 안내하고 고압트랜스포머의 자기력차폐가 가능하며 마그네트론의 각종 단자를 보호할 수 있는 냉각공기흡입안내판을 제공토록함에 그 목적이 있는 것이다.The present invention was devised to solve the above problems, and is installed above the intake port of the cooling duct, guides the intake of external air, shields the magnetic force of the high voltage transformer, and protects various terminals of the magnetron. The purpose is to provide a suction guide plate.

본 고안은 냉각덕트의 흡입구 상측에 좌우 한쌍의 고정편이 부착되고 이 고정편 하부에는 받침편을 형성하며, 흡입공기를 안내하여 자기력을 차폐하는 바닥판과 이로부터 후방으로 벤딩부를 갖는 후판이 형성되며 상기 바닥판의 일측에는 고정후크를 갖는 지지판이 입설되며 상기 벤딩부 일측에는 후크요부를 가진 고정판이 일체로 형성되게 구성한 것이다.According to the present invention, a pair of left and right fixing pieces are attached to the upper side of the inlet of the cooling duct, and a lower part of the fixing piece is formed to form a supporting piece. A support plate having a fixed hook is placed on one side of the bottom plate, and a fixing plate having hook recesses is integrally formed on one side of the bending part.

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

본 고안의 전자렌지의 냉각공기흡입안내판의 구조는 제2도 및 제3도에 도시한 바와 같이 냉각덕트(20)의 흡입구(21) 상측에 좌우 한쌍의 고정편(22)이 부착되고, 이 고정편(22) 하부에도 좌우 한쌍의 받침편(23)을 형성한다. 한편, 흡입공기를 안내함과 동시에 고압트랜스포머의 자기력을 차폐하는 역할의 바닥판(24)과, 이로부터 후방으로 벤딩부(25)를 갖는 후반(26)이 형성되며 상기 바닥판(24) 일측에는 고정후크(27)를 갖는 지지판(28)이 입설되고, 상기 벤딩부(25) 일측으로 후크요부(29)가 형성된 고정판(30)을 일체로 형성한다.The structure of the cooling air suction guide plate of the microwave oven of the present invention has a pair of left and right fixing pieces 22 attached to the upper side of the inlet port 21 of the cooling duct 20 as shown in FIGS. 2 and 3. A pair of left and right support pieces 23 is also formed in the lower portion of the fixing piece 22. On the other hand, the bottom plate 24 which serves to guide the intake air and shield the magnetic force of the high-voltage transformer, and the rear half 26 having the bending portion 25 from the rear side is formed and one side of the bottom plate 24 There is a support plate 28 having a fixed hook 27 is installed, and the fixing plate 30 is formed integrally with the hook recess 29 to one side of the bending portion 25.

이와 같이 구성한 본 고안은 후반(26) 상단이 냉각덕트(20)의 흡입구(21) 상측에 형성된 고정편(22) 내측으로 삽입되게 하고 벤딩부(25) 저면이 받침판(23)에 받쳐지게 하여 조립 설치한다.The present invention configured as described above allows the upper end of the second half 26 to be inserted into the fixing piece 22 formed on the upper side of the suction port 21 of the cooling duct 20, and the bottom surface of the bending part 25 is supported by the support plate 23. Assemble and install.

이와 같이 조립 구성된 본 고안은 송풍팬(5)을 작동함에 따라 전자렌지의 외부공기를 냉각덕트(20)내로 흡입하게 되는데, 이때 송풍팬(5)에 의해 흡입되는 냉각공기가 상기 바닥판(24) 저면으로 안내되어 원활히 덕트(20)내부로 유입하게 되고, 또한 고압트랜스포머로부터 방출되는 자기력이 마그네트론에 미치는 것을 상기 바닥판(24)이 차폐하게 되며 마그네트론의 접속단자를 감싸 주게 되므로 이를 보호할 수 있는 것이다.The present invention constituted as assembled in this way is to suck the outside air of the microwave oven into the cooling duct 20 in accordance with the operation of the blowing fan (5), the cooling air sucked by the blowing fan (5) the bottom plate (24) The bottom plate 24 shields that the magnetic force emitted from the high-pressure transformer is applied to the inside of the duct 20, and the magnetic force emitted from the high pressure transformer is applied to the bottom surface and surrounds the connection terminal of the magnetron. It is.

따라서 본 고안은 바닥판(24)에 의해 전자렌지의 외부공기를 냉각덕트(20)내로 원활히 안내유입하게 되어 냉각효율을 향상시키고 고압트랜스포머의 자기력을 차폐할 수 있음은 물론 마그네트론의 접속단자를 보호할 수 있어 결국에는 제품의 수명을 오래 유지할 수 있는 잇점이 있는 것이다.Therefore, the present invention smoothly guides the outside air of the microwave oven into the cooling duct 20 by the bottom plate 24, thereby improving the cooling efficiency and shielding the magnetic force of the high-voltage transformer, as well as protecting the connection terminal of the magnetron. In the end, there is an advantage in maintaining the life of the product for a long time.
