본 고안은 전자레인지의 턴테이블 구동장치에 관한 것으로, 특히 직접 구동 방식이 아닌 전동구동 방식으로 회전비를 크게 하여 턴테이블의 회전수를 구동모터의 회전수보다 많게 한 턴테이블 구동 장치에 관한 것이다.The present invention relates to a turntable driving apparatus of a microwave oven, and more particularly, to a turntable driving apparatus in which the rotational speed of the turntable is larger than the rotational speed of the driving motor by increasing the rotation ratio by an electric driving method rather than a direct driving method.
종래의 턴테이블 구동장치에 있어서는 제1도에서 도시한바와 같이 캐비티 저판(101)의 하부에 구동 모터(102)가 설치되고, 그 구동 모터의 회전축(103) 상단부에는 턴테이블(104)이 고정 설치되어 있으며, 이때의 구동모터(102)는 감속 장치를 포함하고 있어 일정 회전수 (6RPM)를 얻을 수 있게 되어 있다.In the conventional turntable driving apparatus, as shown in FIG. 1, a driving motor 102 is installed below the cavity bottom plate 101, and a turntable 104 is fixed to an upper end of the rotation shaft 103 of the driving motor. In this case, the drive motor 102 includes a deceleration device to obtain a constant rotation speed (6 RPM).
또한, 캐비티 저판(101)의 상면에는 턴테이블(104)을 지지하여 회전할 수 있도록 3개 이상의 롤러(105)가 롤러 브라켓(106)에 롤러축핀(107)으로서 회동 가능토록 설치되었다.In addition, three or more rollers 105 are installed on the roller bracket 106 as roller shaft pins 107 so as to be rotatable on the upper surface of the cavity bottom plate 101 so as to support and rotate the turntable 104.
이와 같이 된 상태에서 전자 레인지를 작동시키게 되면 턴테이블 구동모터(102)가 작동하여 회전축(103)을 회전시키고 회전축(103)은 턴테이블(104)을 회전시키게 되며, 롤러(105)들은 회전되는 턴테이블을 지지하면서 회전하게 된다.When the microwave oven is operated in this state, the turntable driving motor 102 operates to rotate the rotating shaft 103, and the rotating shaft 103 rotates the turntable 104, and the rollers 105 rotate the turntable. Rotate while supporting.
이와 같은 직접 구동 방식에 있어서는 턴테이블을 구동시킬때 최종적으로 동력을 전달하는 회전축이 큰힘을 받게 되어 변형될 염려가 있으며 일단 설정된 턴테이블의 회전수는 구동모터와 동일하였다.In such a direct drive method, when the turntable is driven, the rotating shaft that finally delivers power is subjected to a large force, which may be deformed. The rotational speed of the turntable once set is the same as that of the driving motor.
본 고안은 이상의 제결점을 보완 해결하기 위하여 모터로 부터의 동력을 드럼 샤프터와 휠샤프트의 연제작동으로 전달될 수 있도록 하되 휠샤프트이 최종 동력 전달 메체인 휠드럼의 외경을 크게하여 회전비를 증가시킴으로써 구동모터의 회전수보다 턴테이블의 회전수가 많게하고 구동지점이 일측면이 되게 하므로써 구동토오크가 적게 걸리도록 안출한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above drawbacks, the present invention allows power from the motor to be transferred to the drum shafter and the wheel shaft's flame retardant operation, but the wheel shaft increases the rotational ratio by increasing the outer diameter of the wheel drum. The rotational speed of the turntable is greater than the rotational speed of the drive motor and the driving point is made to be one side so that the driving torque may be reduced. This will be described in detail with reference to the accompanying drawings.
베이스판(1)을 저판(2) 하부에 간격울 두어 고정 설치하고, 그 중앙에는 하부측에 수평으로 회전드럼(4)이 형성되며 내측에 수직으로 모터축삽입공(5)을 갖는 드럼샤프트(3)를 저판(2) 중앙의 중심축공(6)에 상측이 삽입 돌출될 수 있도록 설치하되, 하단에 와셔(7)를 받치고, 베이스판(1) 중앙 하부면에 고정 설치되는 구동모터(8)의 모터축(9)이 드럼샤프트(3)의 모터축삽입공(5)에 억지 끼워맞춤으로 조립 될수 있게 하여 설치하며, 이에 대하여 일측으로 저판(2) 하면 양측에는 지지브라켓(10,10')을 용접하여 고정설치하고, 이 사이에는 축핀(11)으로써 회동가능토록 일측에는 회전드럼(4)면에 접촉 구동되는 고무롤러(12)가 삽입 설치되고 타측에는 휠드럼(14)이 일체로 형성된 훨샤프트(13)를 끼워서 수평으로 걸어 설치한다. 이때, 휠드럼(14)의 상측은 저판(2)의 대응하는 지점에 형성되는 휠삽입공(15)에 삽입되어 외측으로 약간 돌출되도록 설치된다.The base plate 1 is fixedly spaced apart from the bottom of the bottom plate 2, and a drum is formed at the center thereof with a rotating drum 4 horizontally at the lower side thereof and a motor shaft insertion hole 5 vertically inside the drum shaft. (3) is installed so that the upper side is inserted into the central shaft hole (6) of the center of the base plate (2), the support motor washer (7) at the lower end, the base motor (1) is a drive motor fixed to the lower surface of the center ( 8) the motor shaft 9 of the drum shaft 3 to the motor shaft insertion hole (5) can be assembled by interference fit, and on the opposite side of the bottom plate (2) support brackets (10, 10 ') is welded and installed, between which a rubber roller 12, which is driven in contact with the surface of the rotating drum 4, is inserted in one side so as to be rotatable by the shaft pin 11, and a wheel drum 14 is installed on the other side. The horn shaft 13 integrally formed is inserted to hang horizontally. At this time, the upper side of the wheel drum 14 is inserted into the wheel insertion hole 15 formed at the corresponding point of the bottom plate 2 is installed so as to project slightly outward.
이와 같이 된 상태에서 상부에 턴테이블(16)을 삽입 설치하게 되는데, 그 하면 중앙에는 드럼샤프트(3) 상단에 헐거운 끼워 맞춤으로 삽입되는 삽입홈(17)이 요입 형성되고, 외축 주위 즉, 휠드럼(14)의 상단과 접촉구동되는 부위에는 접촉구동레일(18)이 돌출 형성되어서 상호 연계 작동 가능토록 조립 구성된 것이다.In this state, the turntable 16 is inserted into and installed at an upper portion thereof, and at the center thereof, an insertion groove 17 inserted into the upper portion of the drum shaft 3 by a loose fit is formed in a concave shape, and around the outer shaft, that is, the wheel drum. The contact driving rail 18 is protrudingly formed at the site of contact with the upper end of the 14 so as to be assembled to be interoperable.
이와 같이 구성된 본 고안은 제2도에서 도시한바와 같이 전자레인지를 가동시키면 구동모터(8)가 구동하게 되고 이에 연결된 드럼샤프트(3)가 회전드럼(4)과 일체로 회전하게 된다.In the present invention configured as described above, as shown in FIG. 2, when the microwave oven is operated, the driving motor 8 is driven, and the drum shaft 3 connected thereto rotates integrally with the rotary drum 4.
회전드럼(4)이 회전함에 따라 일측에 횡으로 설치된 휠샤프트(13)의 고무롤러(12)가 접촉구동하면서 샤프트를 회전시키게 되므로 일체형의 휠드럼(14)이 회전하여 상측에 얹혀 설치된 턴테이블(16)을 회전시키게 된다.As the rotary drum 4 rotates, the rubber roller 12 of the wheel shaft 13 installed horizontally on one side rotates the shaft while contacting the turntable, so that the integral wheel drum 14 is rotated and mounted on the upper side of the turntable ( 16) to rotate.
이때, 턴테이블(16) 하면 중앙의 삽입홈(17)은 드럼샤프트(3) 상단에 단순히 헐거운 끼워 맞춤으로 삽입되어있는 상태이므로 여기에서는 중심을 잡아주는 가이드역활만을 하게 되면 실제의 동력전단은 휠드럼(14)의 상측과 턴테이블 하면에 돌출형성된 접촉 구동레일(18)간의 접촉 구동으로 동력이 전달되어 턴테이블이 회전하게 되는 것이다.At this time, since the insertion groove 17 at the center of the turntable 16 is simply inserted into the upper end of the drum shaft 3 by loose fit, in this case, if only the guide role of holding the center is used, the actual power shear is the wheel drum. Power is transmitted by the contact drive between the upper side of the 14 and the contact driving rail 18 protruding from the lower surface of the turntable to rotate the turntable.
이와 같은 본 고안은 휠드럼(14)의 회전수가 구동모터(8)의 회전수보다 많기 때문에 턴테이블 회전수를 많게 할뿐 아니라 턴테이블 중심축선상에 걸리는 힘이 작아지므로 구동모터의 구동 토오크가 적게 걸린다.The present invention has a higher rotation speed of the wheel drum 14 than the rotation speed of the driving motor 8, thereby increasing the turntable rotation speed and reducing the driving torque of the driving motor because the force on the turntable center axis becomes smaller. .
따라서 회전수를 많게 하면 균일 가열이 좋고 회전수 증가로 인한 구동 모터의 원가 절감이 가능케되는 효과가 있다.Therefore, increasing the number of revolutions has the effect that uniform heating is good and the cost of the drive motor can be reduced by increasing the number of revolutions.
