본 고안은 전자렌지의 트레이모터 구동장치에 관한 것으로, 특히, 팬모터 구동권선에 2중구조로 권선을 권회시켜 그 권선을 통하여 트레이모터 구동전원을 발생시키도록 함으로써, 저압트랜스를 삭제할 수 있게 한 전자렌지의 트레이모터 구동장치에 관한 것이다.The present invention relates to a tray motor driving apparatus of a microwave oven, and in particular, by winding a winding in a double structure in a fan motor driving winding to generate a tray motor driving power through the winding, it is possible to eliminate the low voltage transformer It relates to a tray motor driving device of a stove.
일반적으로 전자렌지에 있어서, 트레이를 회전시키기 위한 트레이모터가 캐비티의 하부에 설치되며, 그 트레이모터는 110VAC 이상에서 ELV(Extra Low Voltage)에 해당되는 50VAC(r.m.s) 이하로 낮추어서 구동전원으로 사용하는 트레이모터가 사용되고 있다. 그 이유는 내부배선이라 할지라도 사람의 손으로 접촉하였을때 감전사고등이 일어나지 않는 정도의 전압(ELV)으로 트레이 모터의 구동전원을 사용하기 위함이다.In general, in a microwave oven, a tray motor for rotating the tray is installed at the lower part of the cavity, and the tray motor is lowered to 50 VAC (rms) corresponding to ELV (Extra Low Voltage) at 110 VAC or more and used as a driving power source. Tray motor is used. The reason for this is to use the drive power of the tray motor with a voltage (ELV) that does not cause an electric shock accident when touched by human hands even in the internal wiring.
이에따라 종래에는, 가정용 입력전원(110V/220V)을 50VAC이하로 낮추는 저압트랜스를 사용하여 입력전원을 감압한 후 이를 트레이모터의 구동전원으로 인가하도록 이루어져 있다.Accordingly, in the related art, the input power is reduced by using a low voltage transformer that lowers the household input power (110V / 220V) to 50 VAC or less and then applies it as a driving power of the tray motor.
그러나, 이와같은 종래 전자렌지의 트레이모터의 구동전원을 발생시키기 위해서는, 저압트랜스가 사용되어야 하는 단점이 있다.However, in order to generate the driving power of the tray motor of the conventional microwave oven, there is a disadvantage that a low voltage transformer should be used.
본 고안은 이와같은 종래 문제점을 감안하여 트레이모터 구동용 저압트랜스를 별도로 구비시키지 않고서 냉각팬모터 구동용 권선에 2차 권선을 권회하여 저압트랜스로 대용으로 사용할 수 있게 한 전자렌지의 트레이모터 구동전원 발생장치를 제공함에 목적이 있다.In view of the conventional problems, the present invention does not include a low voltage transformer for driving a tray motor, and a secondary motor is wound around a cooling fan motor driving winding so that a low voltage transformer can be used as a low voltage transformer. It is an object to provide a generator.
이하, 본 고안에 의한 전자렌지의 트레이모터 구동전원 발생장치의 실시예를 첨부된 도면을 참조해서 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings an embodiment of a tray motor driving power generator of a microwave oven according to the present invention will be described in detail.
제1도는 본 고안에 의한 트레이모터 설치 구조도이고, 제2도는 본 고안에 의한 트레이모터 구동전원 발생 겸용 냉각팬모터의 구조도로서 이에 도시된 바와같이 조리실(1)의 하부에 트레이모터(3)가 설치되고, 그 트레이모터(3)의 모터축에 커플링되어 조리실(2)의 내측에 회전트레이(4)가 설치되며, 전장실의 팬모터(10)의 구동권선에 2차권선을 권회하여 그 2차권선을 도선(5)을 통하여 상기 트레이모터(3)의 전원입력단자에 연결하여 구성된다.FIG. 1 is a structural diagram of a tray motor installation structure according to the present invention, and FIG. 2 is a structural diagram of a cooling fan motor for driving and generating a tray motor driving power according to the present invention. As shown therein, a tray motor 3 is disposed below the cooking chamber 1. It is installed, coupled to the motor shaft of the tray motor (3) is provided with a rotary tray (4) inside the cooking chamber (2), and wound the secondary winding to the drive winding of the fan motor (10) of the electric compartment The secondary winding is connected to the power input terminal of the tray motor 3 through the conductive wire 5.
상기 트레이모터(3) 구동전원 발생용 2차권선이 권회된 팬모터(10)는 제2도에 도시된 바와같이 코아(Core)(11)의 일부가 절연브라켓트(12)에 의해 감싸지고, 그 절연브라켓트(12)의 둘레에 팬모터구동용 권선(13)이 권회되어 이루어진 팬모터에 있어서, 그 팬모터 구동용 고정자권선(13)의 외측에 절연재(14)를 씌우고, 그 절연재(14)의 외측에 상기 팬모터 구동용 고정자권선(13)과의 소정의 권선비를 가지는 2차권선(15)을 트레이모터(3) 구동전원 발생용으로 권회하여 그 2차권선(15)의 단부에 연결된 출력단자(16)를 도선(5)을 통해 상기 트레이모터(3)에 연결하여 구성된다.In the fan motor 10 in which the secondary winding for generating the driving power of the tray motor 3 is wound, a part of the core 11 is wrapped by the insulating bracket 12, as shown in FIG. In a fan motor in which a fan motor driving winding 13 is wound around the insulating bracket 12, an insulating material 14 is placed on the outside of the stator winding 13 for fan motor driving, and the insulating material 14 2) the secondary winding 15 having a predetermined winding ratio with the stator winding 13 for fan motor driving is wound for the generation of the drive power of the tray motor 3, and the end of the secondary winding 15 It is configured by connecting the output terminal 16 connected to the tray motor 3 through the conductive wire (5).
이와같이 구성된 본 고안에 의한 전자렌지의 트레이모터 구동장치의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the tray motor driving apparatus of the microwave oven according to the present invention configured as described above are as follows.
본 고안은 트레이모터 구동용 저압트랜스를 사용치 않고서 대신에 팬모터를 이용하여 2차권선을 권회시켜 트레이모터를 구동시키고 있다.The present invention does not use a low-voltage transformer for driving a tray motor, but instead uses a fan motor to wind the secondary winding to drive the tray motor.
팬모터(10)에는 회전력을 발생시키기 위해 코아(11)에 권회된 고정자권선(13)이 존재하므로, 그 팬모터 구동용 고정자권선(13)의 외측에 절연재(14)를 감싼후, 소정의 권선비로 2차권선(15)을 권회시켜 그 2차권선(15)을 통하여 트레이모터(3) 구동용 저압 50VAC를 발생시키도록 되어 있다.Since the stator winding 13 wound around the core 11 exists in the fan motor 10 to generate the rotational force, the fan motor 10 wraps the insulating material 14 on the outside of the stator winding 13 for driving the fan motor. The secondary winding 15 is wound at a turns ratio, and low voltage 50 VAC for driving the tray motor 3 is generated through the secondary winding 15.
이상에서 설명한 바와같이 본 고안에 의하면, 트레이모터의 구동용 전원을 별도의 저압트랜스를 사용치 않고서 팬모터에 2차권선만을 권회시켜 원하는 저압의 구동전압을 얻을 수 있으므로, 저압트랜스 삭제에 따른 경비절감과 그 저압트랜스 설치공간을 줄일 수 있는 효과가 있다.As described above, according to the present invention, it is possible to obtain a desired low voltage drive voltage by winding only the secondary winding to the fan motor without using a separate low voltage transformer for driving the tray motor, so that the cost of eliminating the low voltage transformer is reduced. It is effective to reduce the installation space and the low voltage transformer.
