Abstract

The microwave oven includes a cooking chamber (6) provided with a rotatable tray (2) for placing articles to be cooked. A rotation member (4) includes pairs of arms, each having a relatively longer length arm extending inone direction and a relatively shorter length arm extending in an opposite direction. For supporting the tray, relatively larger members are fixed rotatably to the relatively shorter arms and relatively smaller members rotatably fixed to the relatively longer arms. The rotation member is guided so that it is moved in slant along a predetermined path formed on the bottom of the cooking chamber. The incidence angles of microwaves to articles to be cooked can be varied according to the inclined angles of the tray during its rotation. The microwave oven provides equal dispersal of microwaves over foodstuffs on the rotatable tray.

본 발명은 고주파 가열장치의 트래이(TRAY) 회전구조에 관한 것으로 특히, 트래이를 경사회전케 함으로써 고주파 분산이 효과적으로 이루어지도록 된 고주파 가열장치의 트래이 회전구조에 관한 것이다. 종래의 경우, 고주파 가열장치의 트래이는 전반적으로 도면 제3도에 도시된 바와 같이 지지부재(30)에 착설된 동일직경을 갖는 회전체(40)에 재치되어, 구동수단(50)에 의해 평면수평상태를 유지하면서 회전되는 구조이므로 트래이(20)이 표면에서의 고주파 입, 반사각도가 항상 일정하게 이루어지므로 효율적인 고주파 분산이 이루어지지 못함에 따라 기기의 성능이 저하되는등 여러 결점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray rotating structure of a high frequency heating apparatus, and more particularly, to a tray rotating structure of a high frequency heating apparatus in which a high frequency dispersion is effectively performed by tilting the tray. In the conventional case, the tray of the high frequency heating apparatus is generally mounted on the rotating body 40 having the same diameter mounted on the supporting member 30 as shown in FIG. Since the structure of the tray 20 is rotated while maintaining the horizontal state, since the high frequency particle and reflection angles of the tray 20 are always made constant, there are various defects such as deterioration of the performance of the device due to the failure of efficient high frequency dispersion.

따라서 본 발명은 상기와 같은 종래의 결점을 해소시키기 위해서 지지부재에 착설되는 회전체의 직경을 서로 다른 크기로 하여 트래이를 경사회전케 함으로써, 고주파 분산이 다각도로 골고루 이루어지도록 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is made to be inclined to rotate the tray by making the diameter of the rotating body mounted on the support member to different sizes in order to eliminate the above-mentioned drawbacks, so that the high frequency dispersion is evenly made in multiple angles. When described in detail the configuration and working effects as follows.

지지부재(3)에 착설된 회전체(4) 상면에 재치되어 구동수단(5)에 의해 회동되는 고주파 가열장치(1)의 트래이(2) 회전구조에 있어서, 상기 지지부재(3) 중심으로부터 임의거리 1및 1'만큼 떨어진 위치에 직경이 서로 다른 회전체 A, B(4)(4') (직경 A＞B)를 각각 착설하여 트래이가 소정각도(θ)를 유지하면서 경사회전케 하고, 캐비티(6) 내측하면에는 회전체 A(4)가 안내되는 요홈(6a)을 형성하여 지지부재가 수평회전 되게끔 구성된 것으로 미 설명부호 7은 마그네트론인 것이다. 이와같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.In the rotary structure of the tray 2 of the high frequency heating apparatus 1 mounted on the upper surface of the rotating body 4 mounted on the supporting member 3 and rotated by the driving means 5, from the center of the supporting member 3; Rotors A, B (4) (4 ') (diameter A> B) of different diameters were installed at positions 1 and 1' apart from each other, and the tray was inclinedly rotated while maintaining a predetermined angle (θ). On the inner side of the cavity 6, a recess 6a through which the rotating body A 4 is guided is formed so that the support member is horizontally rotated. The reference numeral 7 is a magnetron. Referring to the effects of the present invention configured as described above are as follows.

고주파 가열장치(1)의 트래이(2)가 상면에 재치되는 지지부재(3) 구조로 도면 제2도에 도시된 본 발명의 것 즉, 지지부재(3)의 중심으로부터 임의거리 1 및 1'만큼 떨어진 지점에 직경이 서로 다른 회전체 A, B(A＞B)(4)(4')가 착설되어 구성된 것을 적용하여 사용하게 되면, 사용자가 캐비티(6) 내측의 트래이(2) 상면에 소정의 조리물을 안착시킨 후 기기의 작동수단을 조작함에 따라 마그네트론(7)으로부터 고주파가 발진되어 캐비티(6) 내부로 분산되면서 지지부재(3)의 회전체 A, B(4)(4') 상면에 재치되어 구동수단(5)에 의해 회전되는 트래이(2) 상면의 조리물을 조리하게 되는데, 이때, 지지부재(3)에 착설된 회전체 A, B(4)(4')의 직경이 서로 다르기 때문에 트래이(2)는 소정각도(θ : 3°-4°정도) 만큼 기울어져 경사회전을 유지하게 되므로 고주파의 입자각도에 따른 반사각이 변화되면서, 재입사를 반복하게 되므로 캐비티(6) 내에서 고주파 분산이 효율적으로 이루어진다.The tray 2 of the high frequency heating apparatus 1 has the structure of the support member 3 mounted on the upper surface of the present invention shown in FIG. 2, that is, an arbitrary distance 1 and 1 'from the center of the support member 3. When the rotors A, B (A> B) (4) (4 ') having different diameters are installed and used at a point separated from each other, the user is placed on the upper surface of the tray (2) inside the cavity (6). After placing a predetermined food, as the operation means of the machine is operated, high frequency is oscillated from the magnetron 7 and dispersed into the cavity 6, thereby rotating the bodies A, B (4) (4 ') of the support member (3). It is placed on the upper surface to cook the food on the upper surface of the tray (2) rotated by the drive means (5), in this case, of the rotating body A, B (4) (4 ') mounted on the support member (3) Since the diameters are different from each other, the tray 2 is inclined by a predetermined angle (θ: about 3 ° -4 °) to maintain inclined rotation. As the square is changed, since the repeated re-enters the high-frequency distribution is made efficiently in the cavity (6).

여기서, 트래이(2)의 경사각도(θ)는 회전체 A, B(4)(4')의 편차에 의해 조정할 수 있다. 한편, 지지부재(3)에 착설된 회전체 A, B(4)(4')는 지지부재(3)의 중심에서 각각 임의거리 1 및 1'만큼 떨어진 위치에 착설되어 있으므로 즉, 회전체 A(4)가 회전체 B(4')보다 짧은 거리에 착설되어 있으므로 지지부재(3)의 회전과정에서 불합리성을 배제할 수 있다. 또, 캐비티(6) 내측하면에서는 요홈(6a)를 형성하여 회전체 A(4)를 안내함으로써 지지부재(3)는 수평상태를 유지하면서 구동수단(5)에 의해 회전된다.Here, the inclination angle θ of the tray 2 can be adjusted by the deviation of the rotating bodies A, B (4) (4 '). On the other hand, the rotors A, B (4), 4 'installed on the support member 3 are installed at positions away from the center of the support member 3 by an arbitrary distance 1 and 1', that is, the rotor A Since (4) is installed at a shorter distance than the rotating body B (4 '), irrationality can be eliminated in the rotation process of the supporting member (3). In addition, on the inner bottom surface of the cavity 6, the groove 6a is formed to guide the rotating body A 4 so that the support member 3 is rotated by the driving means 5 while maintaining the horizontal state.

이상에서 본 바와같이 본 발명은 고주파 가열장치(1)의 지지부재(3)에 착설된 회전체 A, B(4)(4')의 직경을 서로 다른 크기로 하여 트래이(2)를 경사회전케 하는 구조이므로 조리과정에서 고주파 분산이 효율적으로 이루어짐으로 기기의 성능및 기기의 신뢰성을 향상시킬 수 있는 등 여러 장점이 있다.As described above, the present invention obliquely rotates the tray 2 by setting the diameters of the rotating bodies A and B (4) (4 ') mounted on the support member 3 of the high frequency heating apparatus 1 to different sizes. Because of the structure, the high frequency dispersion can be efficiently performed during the cooking process, which can improve the performance and reliability of the device.
