본 고안은 기계식 전자렌지의 마그네트론/히터 구동회로에 관한 것으로, 특히 콤비기능에서 동시가열과 교변가열을 선택할 수 있게 한 전자렌지의 동시/교번가열회로에 관한 것이다.The present invention relates to a magnetron / heater driving circuit of a mechanical microwave oven, and more particularly, to a simultaneous / alternating heating circuit of a microwave oven capable of selecting simultaneous heating and lateral heating in a combination function.

일반적으로 단기능 전자렌지는 가열수단으로서 마그네트론만이 구비되어 있기 때문에 가열시간을 선택하고, 마그네트론의 출력레벨을 선택하게 되면, 타이머에 의해 가열시간 및 출력레벨이 제이되어 마그네트론이 구동되고, 그 마그네트론의 마이크로파 에너지에 의해 요리가 수행되는 것이다.In general, since a single function microwave has only a magnetron as a heating means, when a heating time is selected and an output level of the magnetron is selected, the heating time and output level are set by a timer, and the magnetron is driven. Cooking is carried out by microwave energy of.

그런데, 가열수단으로 마그네트론 이외에 히터를 추가 설치한 다기능 전자렌지에서는, 요리 시간선택 및 마그네트론의 출력조절 이외에 상기 마그네트론 및 히터중 어느하나 또는 동시가열등을 선택하기 위한 선택장치가 필요하고, 이에 따른 콘트롤 회로가 필요하게 된다.However, in a multi-functional microwave oven in which a heater is additionally installed as a heating means, a selection device for selecting any one of the magnetron and the heater or simultaneous heating is required in addition to selecting a cooking time and controlling the output of the magnetron. A circuit is needed.

제1도는 종래 기계식 다기능 전자렌지의 마그네트론/히터 구동회로도로서, 이에 도시된 바와 같이 온/오프 이득에 의해 마그네트론의 출력을 조절하기 위한 가변파워 콘트롤스위치(P. V. C. )(1)와, 그 가변파워 콘트롤스위치(1)를 통한 전원을 마그네트론 구동용 고압트랜스(4)에 인가시켜 마그네트론의 구동을 선택하는 마그네트론 선택스위치(2)와 입력전원을 히터(5)에 인가시켜 히터의 구동을 선택하는 히터선택스위치(3)로 이루어져있다.1 is a magnetron / heater driving circuit diagram of a conventional mechanical multifunction microwave oven, and a variable power control switch (PVC) 1 for controlling the output of the magnetron by an on / off gain as shown therein, and its variable power control Magnetron selection switch (2) which selects driving of magnetron by applying power through switch (1) to magnetron driving high voltage transformer (4) and heater selection to apply driving power by applying input power to heater (5) It consists of a switch (3).

여기서, 상기 가변파워 콘트롤스위치(1)는 출력조절노보를 통하여 마그네트론의 출력을 선택하면, 타이머에 의해 자동으로 온/오프되며, 이때 온/오프 이득은 선택된 출력에 의거해서 조절된다.Herein, when the variable power control switch 1 selects the output of the magnetron through the output control Novo, the variable power control switch 1 is automatically turned on / off by a timer, and the on / off gain is adjusted based on the selected output.

또한, 상기 마그네트론 선택스위치(2) 및 히터선택스위치(3)는 기능선택노보를 통해 마그네트론 및 히터만 콤비선택이 가능하도록 이루어져 있다.In addition, the magnetron selector switch 2 and the heater selector switch 3 are configured so that only the magnetron and the heater can be selected through the function selector.

이와 같이 구성된 종래 다기능 전자렌지의 마그네트론/히터 구동회로에 의하면, 마그네트론만을 구동시키는 경우에는 마그네트론 선택스위치(2)를 온시키고, 히터선택스위치(3)를 오프시키며, 가변파워 콘트롤스위치(1)를 온시켜서 고압트랜스(4)를 구동시킴으로써, 마그네트론만을 구동시킬 수 있게 된다.According to the magnetron / heater driving circuit of the conventional multifunctional microwave oven configured as described above, when only the magnetron is driven, the magnetron select switch 2 is turned on, the heater select switch 3 is turned off, and the variable power control switch 1 is turned on. By turning on the high voltage transformer 4, only the magnetron can be driven.

이때 상기 가변파위 콘트롤스위치(1)를 온/오프시켜 그 온/오프 이득 및 그 온/오프 주기에 의해 마그네트론의 출력을 조절하게 된다.At this time, the variable wave control switch 1 is turned on / off to adjust the output of the magnetron by its on / off gain and its on / off period.

또한, 히터(5)만을 구동시키는 경우에는 상기 마그네트론 선택스위치(2)를 오프시키고, 상기 히터선택스위치(3)를 온시키면 히터(5)만 구동시킬 수 있게 된다.In addition, when only the heater 5 is driven, the magnetron select switch 2 is turned off, and when the heater select switch 3 is turned on, only the heater 5 can be driven.

또한, 마그네트론과 히터(5)를 동시에 구동시키는 콤비기능인 경우에는 마그네트론 선택스위치(2)를 온시키고, 히터선택스위치(3)를 온시키며 가변파워 콘트롤스위치(1)를 온/오프시켜 마그네트론과 히터(5)를 동시에 구동시키면서 마그네트론의 출력을 조절하게 된다.In the case of the combination function of simultaneously driving the magnetron and the heater 5, the magnetron selection switch 2 is turned on, the heater selection switch 3 is turned on, and the variable power control switch 1 is turned on / off to turn on the magnetron and the heater. While driving (5) simultaneously, the output of the magnetron is adjusted.

그러나, 이와 같은 종래 다기능 전자렌지의 마그네트론/히터 구동회로에 의하면, 마그네트론과 히터의 구동을 각각 선택할 수 있음과 아울러 동시 구동을 선택할 수 있으나, 마그네트론과 히터를 교번으로 구동시키에는 불가능하였다.However, according to the magnetron / heater driving circuit of the conventional multifunctional microwave, the driving of the magnetron and the heater can be selected and the simultaneous driving can be selected, but the magnetron and the heater cannot be alternately driven.

즉, 마그네트론과 히터를 교번으로 구동시키기 위해서는 마그네트론 선택스위치와 히터선택스위치를 교대로 온시켜 주어야 하나, 기계식 콘트롤 전자렌지인 경우에는 사용자가 선택노드를 돌려서 선택해주고, 가변파워 콘트롤스위치는 타이머에 의해 자동으로 주기적으로 온/오프 되며 이때 출력조절노브를 통해 선택된 출력크기에 의거한 이득으로 온/오프 되도록 되어 있으므로 사용자가 교대로 선택노브를 절환시켜 마그네트론과 히터를 교번으로 구동시킬 수는 없었다.That is, in order to alternately drive the magnetron and the heater, the magnetron selection switch and the heater selection switch should be turned on alternately. In the case of a mechanical control microwave, the user turns the selection node and selects the variable power control switch by a timer. It is automatically turned on and off periodically. At this time, the output adjustment knob is used to turn on / off the gain based on the selected output size. Therefore, the user cannot alternately drive the magnetron and the heater by switching the selection knob.

따라서 마그네트론과 히터에 의한 동시가열을 선택할 수는 있으나, 교번가열은 선택할 수 없는 단점이 있었다.Therefore, the simultaneous heating by the magnetron and the heater can be selected, but alternate heating was not able to select.

본 고안은 이와 같은 종래 문제점을 감안하여 마그네트론과 히터의 동시가열과 교번가열을 선택할 수 있게 한 전자렌지의 동시/교번 가열회로를 제공함에 목적이 있다.The present invention is to provide a simultaneous / alternating heating circuit of a microwave oven that allows the simultaneous heating and alternating heating of the magnetron and the heater in consideration of such a conventional problem.

이와 같은 본 고안의 목적은, 가동단자가 전원단자에 연결되어 출력조절에 의거해서 타이머에 의해 소정 주기를 가지고 자동으로 a접점과 b접점에 절환되는 가변파워 콘트롤스위치와,The purpose of the present invention is a variable power control switch that is connected to the power terminal and the switch is automatically switched to the contact a and b with a predetermined period by the timer based on the output control, and

가동단자가 마그네트론의 구동전원을 공급하는 고압트랜스의 일차축에 연결되어 a접점을 통해서는 상기 가변파워 콘트롤스위치의 a접점에 연결되고, b접점을 통해서는 상기 가변파워 콘트롤스위치의 b접점에 연결되는 마그네트론 선택스위치와,The movable terminal is connected to the primary axis of the high voltage transformer supplying the driving power of the magnetron, and is connected to the a contact of the variable power control switch through contact a and the b contact of the variable power control switch through contact b. Magnetron selector switch,

가동단자가 히터에 연결되어 상기 가변파워 콘트롤스위치의 b접점을 선택하는 히터선택스위치를 포함시켜 구성함으로써 달성되는 것이다.The movable terminal is achieved by including a heater selection switch connected to the heater to select the b contact of the variable power control switch.

이하, 본 고안에 의한 실시예를 첨부된 도면을 참조해서 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 고안에 의한 전자렌지의 마그네트론/히터 동시/교번 가열회로도로서, 이에 도시된 바와 같이 가동단자(com1)가 전원단자에 연결되어 출력조절에 의거해서 타이머에 의해 소정 주기를 가지고 자동으로 a접점(No1)과 b접점(Nc1)에 절환되는 가변파워 콘트롤스위치(1l)와 가동단자(com2)가 마그네트론(14)의 구동전원을 공급하는 고압트랜스(13)의 일차측에 연결되어 a접점(No2)을 통해서는 상기 가변파워 콘트롤스위치(11)의 a접점(No1)에 연결되고, b접점(Nc2)을 통해서는 상기 가변파워 콘트롤스위치(11)의 b접점(Nc1)에 연결되는 마그네트론 선택스위치(12)와, 가동단자가 히터(15)에 연결되어 상기 가변파워 콘트롤스위치(11)의 b접점(Nc1)을 선택하는 히터선택스위치(16)로 구성된다.2 is a magnetron / heater simultaneous / alternating heating circuit diagram of a microwave oven according to the present invention, and as shown therein, a movable terminal com1 is connected to a power terminal and automatically has a predetermined period by a timer based on an output control. The variable power control switch 1l and the movable terminal com2 switched between the a contact No1 and the b contact Nc1 are connected to the primary side of the high voltage transformer 13 which supplies the driving power of the magnetron 14, and a The contact No2 is connected to the contact a (No1) of the variable power control switch 11, and through the contact b (Nc2) is connected to the contact b (Nc1) of the variable power control switch 11. The magnetron selection switch 12 and the movable terminal are connected to the heater 15 and configured as a heater selection switch 16 for selecting the b contact Nc1 of the variable power control switch 11.

여기서, 상기 가변파워 콘트롤스위치(11)는 출력조절노브를 통해 사용자가 출력세기를 설정하면 그 출력세기에 맞추어서 타이머에 의해 온/오프 이득이 설정되어 자동으로 일정한 주기를 가지고 절환되며, 상기 마그네트론 선택스위치(12) 및 히터 선택스위치(16)는 선택노브에 의해 마그네트론 선택스위치(12)만 a접점(No2)에 온되는 구간,그 마그네트론 선택스위치(12)가 b접점(Nc2)에 온됨과 동시에 히터선택스위치(16)가 온되는구간 히터선택스위치(16)만 온되는 구간을 가지도록 이루어져 있다.Here, when the user sets the output strength through the output control knob, the variable power control switch 11 is switched on and off with a constant period by setting the on / off gain by the timer according to the output strength, the magnetron selection The switch 12 and the heater selector switch 16 are sections in which only the magnetron selector switch 12 is turned on at the contact a (No2) by the selector knob, and the magnetron selector switch 12 is turned on at the contact b (Nc2). Section in which the heater selection switch 16 is turned on is configured to have a section in which only the heater selection switch 16 is turned on.

그리고 상기 고압트랜스(13)의 이차측 고압선원을 고압콘덴서 및 고압다이오드에 의해 정류되어 마그네트론(14)의 구동전원으로 인가되도록 되어 있다.The secondary high voltage source of the high voltage transformer 13 is rectified by a high voltage capacitor and a high voltage diode to be applied as a driving power source of the magnetron 14.

이와 같이 구성된 본 고안에 의하면, 마그네트론(15)만을 구동시키는 경우에는 가변파워콘트롤 스위치(11)를 a접점(No1)에 단락시킨후, 마그네트론 선택스위치(12)를 a접점(No2)에 단락시키면, 마그네트론(14)을 구동시킬 수 있게 된다.According to the present invention configured as described above, when only the magnetron 15 is driven, the variable power control switch 11 is shorted to the contact a (No1), and then the magnetron select switch 12 is shorted to the a contact (No2). The magnetron 14 can be driven.

이때, 히터선택스위치(16)는 오프시키며, 출력조절에 의거해서 타이머가 상기 가변파워콘트롤 스위치(11)를 a접점(No2)과 b접점(Nc2)에 주기적으로 절환시키게 되면, 그 절환 이득에 의해 마그네트론(14)의 출력이 조절된다.At this time, the heater selection switch 16 is turned off, and when the timer periodically switches the variable power control switch 11 to contact a (No2) and contact b (Nc2) based on the output adjustment, The output of the magnetron 14 is adjusted by this.

또한 히터(15)만을 구동시키는 경우에는, 가변파워 콘트롤스위치(11)를 b접점(Nc1)에 단락시킨후, 히터선택스위치(16)를 온시키면, 히터(15)만 구동시킬수 있게 된다. 이때, 마그네트론 선택스위치(12)는 a접점(No2)에 단락된다.When only the heater 15 is driven, the variable power control switch 11 is short-circuited to the contact b Nc1, and the heater selection switch 16 is turned on, so that only the heater 15 can be driven. At this time, the magnetron selection switch 12 is short-circuited to the contact a (No2).
