본 고안은 회전테이블 방식의 전자레인지에 있어서, 테이블을 받쳐주는 받침용 로울러에 대한 것이다.The present invention relates to a support roller for supporting a table in a microwave oven of a rotary table type.

종래의 회전테이블 방식의 전자레인지에 있어서, 테이블을 받쳐주면서 회전되는 로울러는 그 양끝의 직경이 동일한 직사각형의 단면을 가지는 형상으로 된 것이었다. 따라서 이러한 형상의 로울러는 제 4 도에서 보는 바와같이 자연상태에서 회전 주행되는 궤적이 화살표(×)방향의 직진형이기 때문에 회전테이블의 받침로울러로서는 매우 부적합하다는 것을 알 수 있다.In a conventional rotary table type microwave oven, a roller rotating while supporting a table has a shape having a rectangular cross section with the same diameter at both ends. Therefore, it can be seen that the roller having such a shape is very unsuitable as the support roller of the rotating table because the trajectory that rotates in the natural state is straight in the direction of the arrow (×) as shown in FIG.

즉, 테이블(5')이 1회전할 때 로울러(1')는 "n"회전한다고 가정하면 로울러의 내측원주(A)가 구른 총길이와 외측원주(B)가 구른 총길이는 동일하게 되지만 로울러의 내측원주(A)와 접하는 테이블(5')의 내측원주(a)와, 로울러의 외측원주(B)와 접하는 테이블의 외측원주(a')는 각기 그 반경(R)(R')이 다르고, 테이블의 내외측 원주(a)(a')의 길이 역시 각기 다른데도 이들과 접하는 로울러의 내외측원주(A)(B)의 구른 총길이는 동일하게 되므로 결국, 로울러는 인위적인 강제회전을 하게되어 원주(a)와 원주(a')의 차이만큼 로울러면과 이에 접하는 테이블의 접촉면에서 미끄럼현상이 발생되기 때문에 테이블을 회전시키는 모우터와 로울러의 구름부분에 마찰력이 가중되어 무리를 주게되므로 모우터와 로울러의 수명이 단축되며 또 모우터에 걸리는 부하가 커지기 때문에 소비전력도 많아지는 등의 결점이 있었다.In other words, assuming that the roller 1 'rotates "n" when the table 5' rotates once, the total length rolled by the inner circumference A of the roller and the outer roll circumferential B are the same, but The inner circumference a of the table 5 'in contact with the inner circumference A and the outer circumference a' of the table in contact with the outer circumference B of the roller are different in radius R and R ', respectively. Since the lengths of the inner and outer circumferences (A) and (B) of the rollers in contact with them are the same even though the lengths of the inner and outer circumferences (a) and (a ') of the table are different, the rollers are forced to rotate artificially. Since a sliding phenomenon occurs at the contact surface between the roller surface and the contacting surface of the roller as much as the difference between the circumference (a) and the circumference (a '), the friction force is added to the motor rotating the table and the rolling part of the roller, which gives a high pressure. And the life of the roller is shortened, and the load on the motor increases. The drawback was that power consumption increased.

본 고안은 이와같은 문제점을 해결하기 위해 내측직경과 외측직경을 각기 달리하여 단면이 사다리꼴 형상으로 되도록한 로울러를 사용하여 로울러의 구름궤적과 테이블의 회전궤적이 일치되도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.The present invention is designed to match the rolling trajectory of the roller and the rotational trajectory of the table by using a roller whose cross section is trapezoidal shape with different inner diameter and outer diameter to solve this problem. Is as follows.

내측원주(2)보다 외측원주(2')가 적정하게 큰 단면이 사다리꼴 형상으로된 로울러(1)를 수직의 지지틀(3)(3')에 측(4)으로 수평상태가 되게 착설하고, 로울러(1)와 접촉하는 테이블(5)의 접촉면(6)을 로울러(1)의 외주면 경사각과 같은 각도로 경사지게 성형하여서된 것이다.A roller 1 having a trapezoidal shape in which a cross section of the outer circumference 2 'is appropriately larger than the inner circumference 2 is installed on the vertical support frame 3, 3' so as to be horizontal to the side 4, , The contact surface 6 of the table 5 in contact with the roller 1 is formed to be inclined at an angle equal to the inclination angle of the outer circumferential surface of the roller 1.

미설명 부호 "7"은 모우터이다.Unexplained symbol "7" is a motor.

이와같이 구성된 본 고안은 로울러(1)의 내측원주(2)는 테이블(5)의 내측원주(a)와, 외측원주(2')는 외측원주(a')와 각기 접촉궤적(S)이 일치되도록 로울러(1)의 내외측직경을 달리하여 단면이 사다리꼴 형상으로 되도록 성형하였기 때문에 테이블(5)이 회전될 때 로울러(1)와의 접촉면 사이에서 전혀 미끄럼현상이 발생되지 않게 되므로 모우터(7)와 로울러(1)의 수명이 길어지며, 또 이에따라 테이몰(5)의 회전상태가 원활하게 되고 모우터(7)에 큰 부하가 걸리지 않게 되어 소비전력도 감소되는 등의 효과를 얻을 수 있게 되는 것이다.The present invention configured as described above has the inner circumference 2 of the roller 1 having the inner circumference a of the table 5 and the outer circumference 2 'having the outer circumference a' and the contact trajectory S, respectively. Since the cross section is shaped to have a trapezoidal shape by varying the inner and outer diameters of the roller 1, the sliding phenomenon is not generated at all between the contact surface with the roller 1 when the table 5 is rotated. And the life of the roller 1 is long, and accordingly, the rotational state of the taper 5 is smoothed, and a large load is not applied to the motor 7, thereby reducing the power consumption. will be.

또한 단면이 사다리꼴 형상으로 된 본 고안의 로울러(1)를 사용함에 있어서는, 로울러(1)와 테이블(5)의 접촉면(6)은 서로 선접촉상태를 유지토록 해야되므로 제 1 도에서와 같이 로울러(1)는 측(4)으로 수평상태가 되게 착설하되 테이블(5)의 접촉면(6)을 로울러(1)의 외주면 경사각(Q)과 일치되도록 경사지게 성형하였기 때문에 이들의 접촉면은 이들이 선접촉을 하게되어 회전작동이 원활하게 이루어지는 것이다.In addition, in using the roller 1 of the present invention having a trapezoidal cross section, the contact surface 6 of the roller 1 and the table 5 should be kept in line contact with each other, as shown in FIG. (1) is installed horizontally to the side (4), but the contact surface 6 of the table (5) is formed to be inclined to match the inclination angle (Q) of the outer peripheral surface of the roller (1), so their contact surface they are in line contact The rotation operation is made smoothly.

이와같이 작동되는 본 고안은 테이블과 로울러의 궤적이 서로 일치되므로 단면이 직사각형상으로 된 로울러를 사용하던 종래의 전자레인지에 비하여 로울러와 모우터의 수명이 길고 소비전력이 절감되는 등 매우 효과적인 고안이다.The present invention, which operates as described above, is very effective because the trajectories of the table and the roller coincide with each other, such that the life of the roller and the motor is longer and the power consumption is reduced, compared to the conventional microwave oven which uses a roller having a rectangular cross section.
