본 고안은 전자 레인지의 균일 가열 장치에 관한 것으로 특히 반사판을 회전 안테나와 공전하도록 하고 회전안테나가 차지하는 점유공간을 감소시켜 가열실을 효율적으로 사용하여 회전안테나 방식의 전자레인지에 적당하도록한 균일 가열장치에 관한 것이다.The present invention relates to a uniform heating device for a microwave oven, and in particular, to make the reflector revolve with the rotating antenna and reduce the space occupied by the rotating antenna, so that the heating chamber can be efficiently used to make it suitable for the microwave of the rotating antenna type. It is about.
종래의 균일 가열장치는 회전 안테나를 이용하여 피 가열물을 가열하므로 가열실에 회전 안테나가 차지하는 점유공간이 크므로 가열실의 유효공간이 작아지는 결함이 있었다.In the conventional uniform heating apparatus, since the object to be heated is heated using the rotating antenna, the space occupied by the rotating antenna in the heating chamber is large, so that the effective space of the heating chamber is reduced.
따라서 본 고안은 상기한 결함을 개선시킬 목적으로 회전 안테나가 점유하는 공간을 감소시켜 가열실의 유효공간을 증가시키며 반사판을 회전 안테나와 공정하도록하여 전파를 가열실 내부로 불균일 하게 투입시켜 균일가열 효과를 증가시키려는 것이다.Therefore, the present invention reduces the space occupied by the rotating antenna in order to improve the above-mentioned defects, thereby increasing the effective space of the heating chamber, and allowing the reflector to be processed with the rotating antenna so that the radio waves are unevenly introduced into the heating chamber to achieve uniform heating effect. To increase.
종래의 균일 가열장치는 다음과 같은 구성으로 제1도에 따라 설명하면 마그네트론(15)이 부착된 도파관(14)을 가열실(18) 상측에 형성하고 도파관(14)상측에 모터(13)를 부착하여 저유전체의 연결체 (12c)로 회전안테나(12)를 접속하여 회전안테나(12)의 수직부(12a)는 도파관(14)에 위치하고 종단부(12b)는 가열실(18)내부에 위치하도록하며 가열실(18) 하측에 피가열물(17)을 얹은 트레이(16)를 설치한 구성이다.In the conventional uniform heating apparatus, the waveguide 14 having the magnetron 15 attached thereto is formed above the heating chamber 18 and the motor 13 is disposed above the waveguide 14. By attaching the low-dielectric connector 12c to connect the rotary antenna 12 so that the vertical portion 12a of the rotary antenna 12 is located in the waveguide 14 and the terminal 12b is located inside the heating chamber 18. It is positioned so that the tray 16 on which the heated object 17 is placed below the heating chamber 18 is installed.
상기한 구성의 균일 가열 장치는 마그네트론(15)에서 발진된 전파는 도파관(14)을 통해 진행되어 회전안테나(12)의 수직부(12a)에 접속되고 표면파를 이루어 종단부(12b)에 집중되며 모타(13)에 의해 회전안테나(12)는 회전하면서 전파를 가열실(18)내부로 회전 분사시켜 피가열물(17)을 가열시키며 모타(13)와 회전안테나 (12)는 저유전체의 몰드(Mold)물로 형성된 연결체(12c)로써 접속시킨다. 이때 회전안테나(12)는 가열실(18)내에 ℓ2만큼의 공간을 차지하게되어 가열실(18)의 유효공간이 감소하는 결함이 발생하였다.In the uniform heating device having the above-described configuration, the radio wave oscillated from the magnetron 15 travels through the waveguide 14 and is connected to the vertical portion 12a of the rotating antenna 12 and forms a surface wave to concentrate on the terminal portion 12b. The rotary antenna 12 is rotated by the motor 13 while rotating the electric wave into the heating chamber 18 to heat the heated object 17. The motor 13 and the rotary antenna 12 are formed of a low dielectric mold. It is connected by the connecting body 12c formed of (Mold) water. At this time, the rotary antenna 12 occupies the space of l 2 in the heating chamber 18, and a defect occurs in which the effective space of the heating chamber 18 is reduced.
본 고안은 상기한 결함을 개선시키기 위한 것으로 제2도에 따라 설명하면 다음과 같다.The present invention is to improve the above-described defects as described in accordance with FIG.
원형의 반사판(5)을 제4도에 도시한 바와같이 45°각도로 절곡하여 경사면(5a)을 형성하고 그와 일체로 원형의 지지평판(5b)을 형성하고 반사판(5)의 제3도에 도시한바와같이 중안에 홀(11)을 형성하고 그 주벼에 걸림돌출부(10)를 형성하여 회전안테나(4)의 수평부(4b)가 위치하도록하며 하측은 카바(19)를 장착하여 도파관(4)과 연통되도록하여 가열실(9)의 점유 면적을 줄이고 피 가열물(8)을 균일하게 가열시키도록 구성된 것이다.As shown in FIG. 4, the circular reflector 5 is bent at an angle of 45 ° to form the inclined surface 5a, and the circular support plate 5b is integrally formed therewith. As shown in the figure, the hole 11 is formed in the middle, and the locking protrusion 10 is formed in the rice paddle so that the horizontal portion 4b of the rotating antenna 4 is positioned, and the lower side is equipped with a cover 19 to mount the waveguide. It is configured to communicate with (4) to reduce the occupied area of the heating chamber 9 and to uniformly heat the heated object 8.
상기한 구성의 균일가열장치는 제2도에 도시한 바와같이 마그네트론(1)에서 발진된 전파는 도파관(2)을 통해 진행되어 회전 안테나(4)의 수직부(4a)에 집중되며 상기 전파는 표면파를 형성하여 회전안테나(4)의 수평부(4b)에 접속된다.In the uniform heating device having the above-described configuration, as shown in FIG. 2, the radio wave generated from the magnetron 1 travels through the waveguide 2 and is concentrated on the vertical portion 4a of the rotating antenna 4, and the radio wave is A surface wave is formed and connected to the horizontal portion 4b of the rotating antenna 4.
이때 회전안테나(4)는 모터(3)에 의해 회전되어 반사판(5)을 회전안테나(4)의 회전방향으로 반경 ℓ3의 크기로 공전운동을 한다. 즉 반사판(5)의 회전은 회전안테나(4)의 수평부(4b)가 걸림돌출부(10)를 밀어주므로써 회전하게되며 회전안테나(4)의 수평부(4b)에서 투사된 전파는 경사면(5a)에 직접 반사되어 가열실(9)내부로 투사시켜주며 가열실(9)에서 반사된 전파는 반사판(5)에 의해 불균일하게 재반사 시키므로써 피 가열물(8)을 균일하게 가열시킨다.At this time, the rotary antenna 4 is rotated by the motor 3 to perform the orbiting movement of the reflector 5 in the radius l 3 in the rotation direction of the rotary antenna 4. That is, the rotation of the reflector 5 is rotated by the horizontal portion 4b of the rotating antenna 4 pushing the locking projection 10, and the radio wave projected from the horizontal portion 4b of the rotating antenna 4 is inclined surface ( 5a) is directly reflected to the inside of the heating chamber 9, and the radio wave reflected from the heating chamber 9 is reflected back unevenly by the reflecting plate 5 to uniformly heat the object to be heated 8.
이때 반사판(5)은 카바(19)를 따라 지지평판(5b)이 미끄러지면서 회전하게되며 회전안테나(4)는 가열실(9)내부에서 ℓ1만큼 차지하게되어 가열실(9)의 유효공간을 증가시키게 된다. 따라서 본 고안에 따른 균일가열장치는 회전안테나(4)가 차지하는 비율이 감소되어 가열실(9)내의 유효공간을 증가시키게 되고 반사판(5)에 전파를 회전분사시키고 또한 가열실(9)에 반사된 전파를 불균일하게 난반사시켜 균일가열 효과를 높일수 있으며 반사판(5)의 표면을 울퉁불퉁하게 형성시켜 난반사 효과를 높일수 있는 장점이 있다.At this time, the reflector plate 5 rotates while the support plate 5b slides along the cover 19, and the rotating antenna 4 occupies as much as 1 in the inside of the heating chamber 9 so that the effective space of the heating chamber 9 is maintained. Will increase. Therefore, the uniform heating device according to the present invention reduces the proportion of the rotary antenna 4 to increase the effective space in the heating chamber (9) and to rotate and spray the radio wave to the reflecting plate (5) and also reflected in the heating chamber (9) It is possible to increase the uniform heating effect by irregularly reflecting the radio waves uniformly and to form the surface of the reflecting plate 5 unevenly to increase the diffuse reflection effect.
