본 고안은 기계식전자레인지의 해동시간 지연회로에 관한 것이다.The present invention relates to a thawing time delay circuit of a mechanical microwave oven.

제 1도는 종래의 기계식전자레인지의 회로도를 나타낸 것이다.1 shows a circuit diagram of a conventional mechanical microwave oven.

교류입력의 일단에 램프(L) 및 1차안전스위치(SW1)와 모스터스위치(SW2)을 연결하고, 타단에 퓨즈(F)와 감은스위치(Thermostatic switch SW6)를 통해 타이머스위치(SW5)에 연결하며, 램프(L)를 스위치(SW1, SW2, SW5)에 각각 연결하고, 스위치(SW1)를 팬모터(MF), 출력조절모터(MDF), 타이머모터(MT) 및 고압트랜스(HVT)의 1차측에 연결하며, 스위치(SW3)의 일단을 팬모터(MF), 출력조절모터(MDF) 및 타이머모터(MT)에 연결함과 동시에 타단을 스위치(SW1, SW5)에 각각 연결하고, 스위치(SW4)를 고전압트랜스(HVT)의 1차측에 연결하며, 2차측에 마그네트론(MGT), 고압콘덴서(HVC) 및 고압다이오드(HVD)를 각각 연결 구성하였다.Connect the lamp (L) and the primary safety switch (SW 1 ) and the master switch (SW 2 ) to one end of the AC input, and connect the timer switch (F) and the winding switch (Thermostatic switch SW 6 ) to the other end. SW 5 ), and connect the lamp (L) to the switches (SW 1 , SW 2 , SW 5 ), respectively, and connect the switch (SW 1 ) to the fan motor (MF), output control motor (MDF), and timer motor ( Connect to the primary side of MT) and high voltage transformer (HVT), and connect one end of switch (SW 3 ) to fan motor (MF), output control motor (MDF) and timer motor (MT) and at the same time, switch the other end. SW 1 , SW 5 ), and switch SW 4 to the primary side of the high voltage transformer (HVT), and the magnetron (MGT), high voltage capacitor (HVC) and high voltage diode (HVD) to the secondary side, respectively. Connection was made.

상기 구성된 기계식 전자레인지는 전원을 인가한 후 레인지의 문을 닫으면, 모니터스위치(SW2)가 오프되고 1차 안전스위치(SW1)가 온이되며, 타이머모터(MT)를 들여 동작시간을 설정하면 타이머스위치(SW5)가 온이된다. 또한 출력조절모터(MDF)의 눈금(Knob)을 돌려 출력을 조절하는데, 출력이 예를 들어 강 또는 해동 2개인 경우 본 고안에서는 해동으로 설정한다.When the mechanical microwave oven is configured to close the door after applying power, the monitor switch SW 2 is turned off and the primary safety switch SW 1 is turned on, and the operating time is set by entering the timer motor MT. The timer switch SW 5 is turned on. In addition, by adjusting the output Knob of the output control motor (MDF) to adjust the output, if the output is, for example, two strong or thawing, in the present invention set to thawing.

상기한 바와 같이 출력을 조절한 후 스타트 스위치(SW3)를 온시키면 전원에서 인가된 전압이 고압트랜스(HVT)에 인가되며 고압트랜스(HVT)의 2차측에 유기되는 전압에 의해 마그네트론(MGT)이 발진한다. 이때 출력조절스위치(SW4)가 출력조절모터(MDF)의 캠(Cam)작용에 의해 주기적으로 온, 오프되어 고압트랜스(HVT)에 인가되는 전압을 단속하므로써 출력을 조절한다. 타이머모터(MT)의 설정시간이 완료되면 타이머모터(MT)의 캠작용에 의해 타이머스위치(SW5)가 오프되어 전자레인지의 동작이 완료된다.When the start switch SW 3 is turned on after adjusting the output as described above, the voltage applied from the power source is applied to the high voltage transformer HVT and the magnetron MGT is induced by the voltage induced on the secondary side of the high voltage transformer HVT. This rashes. At this time, the output control switch SW 4 is periodically turned on and off by the cam action of the output control motor MDF to regulate the output by controlling the voltage applied to the high voltage transformer HVT. When the set time of the timer motor MT is completed, the timer switch SW 5 is turned off by the cam action of the timer motor MT to complete the operation of the microwave oven.

그러나, 상기 회, 로는 타이머모터의 최대설정시간이 조리가능시간 즉 해동시간이었다. 이 경우 최대조리 가능시간보다 실제해동시간이 더 길면 즉, 최대조리가능 시간이 15분이고, 음식물의 실재해동시간이 20분이라면, 상기와 같은 동작에 의해 15분동안 해동을 실시하고, 다시 타이머 모터(MT)를 돌려 동작시간을 5분으로 설정한 후 상기와 같은 동작을 반복해야 하는 문제점이 있었다.However, in the above-mentioned furnace, the maximum setting time of the timer motor was the cooking time, that is, the thawing time. In this case, if the actual thawing time is longer than the maximum cooking time, that is, if the maximum cooking time is 15 minutes and the actual thawing time of the food is 20 minutes, thaw for 15 minutes by the above operation, and then again After turning the MT to set the operation time to 5 minutes, there was a problem of repeating the above operation.

본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 타이머 모터의 인입선을 출력조절스위치의 뒷단에 연결하여 해동시간이 실제타이머의 설정시간보다 길게 되도록 해동시간을 지연시키는 기계식 전자레인지의 해동시간지연회로를 제공함에 그 목적이 있다.The present invention was devised to solve the above problems, and the thawing time of the mechanical microwave oven is delayed so that the thawing time is longer than the actual timer setting time by connecting the lead wire of the timer motor to the rear end of the output control switch. The purpose is to provide a delay circuit.

이하에 첨부된 도면에 의거하여 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제 2도는 본 고안의 실시예에 따른 회로도를 나타낸 것이다.2 shows a circuit diagram according to an embodiment of the present invention.

본 고안은 제 1도의 타이머모터(MT)의 인입선을 출력조절스위치(SW4)의 뒷단과 고압트랜스(HVT)의 1차측 사이에 연결하여 출력조절스위치(SW4)가 온될때만 타이머모터(MT)를 동작시키므로써 출력조절스위치(SW4)가 온되는 시간 동안만을 누적시켜, 그 누적시간이 타이머설정 시간이 될때까지 전자레인지가 동작하도록 연결 구성하였다.The present invention connects the lead wire of the timer motor MT of FIG. 1 between the rear end of the output control switch SW 4 and the primary side of the high voltage transformer HVT so that only when the output control switch SW 4 is turned on. By operating MT), only the time during which the output control switch SW 4 is turned on is accumulated, and the microwave oven operates until the accumulated time becomes the timer setting time.

즉, 출력조절스위치(SW4)가 "강"에 위치해 있을 경우에는 스위치(SW4)가 항상 온이 되어 타이머설정시간동안만 동작하고, 출력조절스위치(SW4)가 "해동" 위치에 있을 경우에는 출력조절스위치(SW4)가 주기적으로 온, 오프되어 타이머모터가 출력조절스위치(SW4)의 온 시간동안만 동작하도록 연결구성하였다.That is, when the output control switch (SW 4 ) is located in the "strong" position, the switch (SW 4 ) is always on and operates only for the timer set time, and the output control switch (SW 4 ) is in the "thaw" position In this case, the output control switch SW 4 is periodically turned on and off so that the timer motor is connected to operate only during the on time of the output control switch SW 4 .

상기 구성된 본 고안의 동작을 설명하면 다음과 같다. 먼저, 전원을 인가한 후 전자레인지내에 요리하고자 하는 음식물을 넣고 도어를 닫으면, 모니터스위치(SW2)의 접점이 떨어져 오프되고, 1차안전스위치(SW1)의 접점이 접속되어 온이된다.Referring to the operation of the present invention configured as described above are as follows. First, when power is applied and food is to be cooked in the microwave and the door is closed, the contact of the monitor switch SW 2 is separated and turned off, and the contact of the primary safety switch SW 1 is connected and turned on.

타이머모터(MT)의 눈금을 돌려 조리하고자 하는 시간을 설정하면 타이머스위치(SW5)는 온이되고, 램프(L)가 점등된다.The timer switch SW 5 is turned on and the lamp L is turned on by setting the time to cook by turning the scale of the timer motor MT.

출력조절모터의 출력조절눈금을 돌려 출력으로 "강" 또는 "해동" 을 선택한다.Turn the output adjustment scale on the output control motor to select "strong" or "thaw" for the output.

스타트스위치(SW3)를 누르면 팬모터(MF) 및 출력조절모터(MDF)에 전원이 인가되고, 출력조절모터(MDF)의 캠작용에 의하여 출력조절스위치(SW4)가 주기적으로 온, 오프된다. 따라서 타이머모터(MT) 및 고압트랜스(HVT)의 1차측에 주기적으로 전원이 인가되므로 타이머모터(MT)는 출력조절스위치(SW4)의 온시간동안만 동작하고, 출력조절스위치(SW4)의 온시간동안 고압트랜스(HVT)의 1차측에 전압이 인가되어 2차측에 유기전압이 발생되므로 마그네트론(MGT)이 발진한다.When the start switch (SW 3 ) is pressed, power is supplied to the fan motor (MF) and the output control motor (MDF), and the output control switch (SW 4 ) is periodically turned on and off by the cam action of the output control motor (MDF). do. Therefore, the timer motor (MT), and therefore periodically supply power to the primary side of the high voltage transformer (HVT) timer motor (MT) is the output control switch on time in operation, and the output control switch (SW 4) for the (SW 4) Since the voltage is applied to the primary side of the high voltage transformer (HVT) during the on time, the induced voltage is generated on the secondary side, the magnetron (MGT) oscillates.

상기와 같이 타이머모터(MT)가 출력조절스위치(SW4)의 온, 오프에 따라 주기적으로 동작하므로 전체적인 전자레인지의 동작시간은 출력조절스위치(SW4)가 온되는 시간만을 누적시킨 것이 되어 해동시간은 상대적으로 길어 진다.Operating time of the overall microwave, so the timer motor (MT) is periodically operated according to the on and off the output control switch (SW 4) as described above are thawed is that which accumulate only the time at which the output control switch (SW 4) on The time is relatively long.

상기 동작을 예를 들어 설명하면 다음과 같다.The above operation will be described by way of example.

타이머의 최대설정시간이 15분이고 출력조절스위치(SW4)가 18초동안 오프, 12초동안 온으로 해동할때 즉, 40%로 해동할때 해동가능시간은 다음과 같다.When the maximum set time of the timer is 15 minutes and the output control switch (SW 4 ) is defrosted for 18 seconds off and on for 12 seconds, that is to say 40%, the defrosting time is as follows.

즉 실제행동 가능한 시간은 37분 30초가 된다.In other words, the actual actionable time is 37 minutes 30 seconds.

만약 출력조절모터(MDF)의 출력조절을 "강"으로 하면, 출력조절스위치(SW4)는 항상 온이 되어있으므로 타이머모터(MT)에 의해 설정된 시간동안만 전자레인지가 동작하게 된다.If the output control of the output control motor (MDF) is "strong", the output control switch (SW 4 ) is always on, so that the microwave oven operates only for the time set by the timer motor (MT).

본 고안에 따르면, 타이머모터(MT)의 인입선을 출력 조절스위치(SW4)의 뒷단과 고압트랜스(HVT)의 1차측에 접속하여 최대설정시간이 짧은 기계식 전자레인지의 해동시간을 상대적으로 증가시킬 수 있으므로 타이머의 설정시간을 불필요하게 증가시킬 필요가 없으며 짧은 타이머의 최대설정 시간으로 긴시간동안의 해동동작을 할 수 있다.According to the present invention, the lead wire of the timer motor MT is connected to the rear end of the output control switch SW 4 and the primary side of the high voltage transformer HVT to relatively increase the thawing time of the mechanical microwave oven having a short maximum setting time. Therefore, it is not necessary to increase the set time of the timer unnecessarily, and the long set time can be defrosted by the maximum set time of the short timer.
