도 1은 본 발명의 실시예에 따른 저주파 전자기장 발생 장치를 개략적으로 도시한 도면이다.1 is a view schematically showing a low-frequency electromagnetic field generating device according to an embodiment of the present invention.
도 1을 참조하면, 저주파 전자기장 발생 장치(10)는 컨트롤 패널(100), 전원 장치(200), 고압 저주파 인버터 회로(500) 및 방전체(400)를 포함할 수 있다.Referring to FIG. 1, the low-frequency electromagnetic field generating device 10 may include a control panel 100, a power supply device 200, a high-voltage low-frequency inverter circuit 500, and a discharge body 400.
여기서, 본 실시예의 저주파 전자기장 발생 장치(10)는, 식품 등 수분을 함유한 물품을 특정 처리(예를 들어, 보관)하는 다양한 종류의 설비(또는 장비, 시설)에 적용될 수 있다. 이와 같은 설비는, 본 실시예에서 저주파 전자기장 적용 설비로 칭하여 질 수 있다.Here, the low-frequency electromagnetic field generating device 10 of the present embodiment can be applied to various types of facilities (or equipment, facilities) for specific treatment (for example, storage) of articles containing moisture, such as food. Such a facility may be referred to as a low frequency electromagnetic field application facility in this embodiment.
이와 같은 저주파 전자기장 적용 설비에 관해 예를 들면, 저주파 전자기장 발생 장치(10)는, 냉장고, 냉동고, 해동고, 온장고, 건조기, 튀김기 등의 식품 처리 설비나, 어항, 수경재배시설 등에 설치될 수 있다. 더욱이, 혈액 등을 보관하는 의료용 보관 설비에도 설치될 수 있다. 또한, 치료용 설비로서 사우나 등에 설치될 수 있다.Regarding such a low-frequency electromagnetic field application facility, for example, the low-frequency electromagnetic field generating device 10 may be installed in a food processing facility such as a refrigerator, a freezer, a thaw freezer, a warm cabinet, a dryer, a fryer, a fish tank, and a hydroponic cultivation facility. . Moreover, it may be installed in a medical storage facility that stores blood and the like. In addition, it can be installed in a sauna or the like as a treatment facility.

Freshness can be maintained.
전원 장치(200)는 컨트롤 패널(100)과 고압 저주파 인버터 회로(500)에 전원을 공급한다.The power supply 200 supplies power to the control panel 100 and the high-voltage low-frequency inverter circuit 500.
한편, 저주파 전자기장 발생 장치(10)에서 다수의 고압 저주파 인버터 회로(500) 및 방전체(400)가 사용될 수 있다. 이 경우에, 컨트롤 패널(100)과 전원 장치(200)는, 다수의 고압 저주파 인버터 회로(500) 및 방전체(400)와 병렬로 연결되어 다수의 방전체(400)를 통하여 다 채널의 저주파 전자기장을 생성할 수 있다.Meanwhile, a plurality of high-voltage low-frequency inverter circuits 500 and discharge bodies 400 may be used in the low-frequency electromagnetic field generating device 10. In this case, the control panel 100 and the power supply 200 are connected in parallel with a plurality of high-voltage low-frequency inverter circuits 500 and a discharge body 400, and a multi-channel low frequency through a plurality of discharge bodies 400. An electromagnetic field can be generated.
컨트롤 패널(100)은 방전체(400)에서 출력할 주파수 및 전압을 조절하는 기능을 한다.The control panel 100 functions to control the frequency and voltage to be output from the discharge body 400.
전원 장치(200)는 전원을 공급하는 장치로서, 바람직하게는 SMPS 전원장치를 사용할 수 있으며, 차량용 24~48V 전원이나 가정용 110-220V 전원을 고압 저주파 인버터 회로(500)가 사용할 전압 및 컨트롤 패널(100)이 사용할 전압으로 바꿀 수 있다.The power supply 200 is a device for supplying power, preferably an SMPS power supply can be used, and a voltage and control panel used by the high-voltage low-frequency inverter circuit 500 for vehicle 24~48V power or household 110-220V power ( 100) can be changed to the voltage to be used.
또한, 전원 장치(200)는 교류 및 직류 기능을 구비하여 상용 전원이나 밧데리로도 작동시킬 수 있다.In addition, the power supply device 200 is provided with AC and DC functions, and can be operated with a commercial power supply or a battery.
고압 저주파 인버터 회로(500)는, 예를 들면, 전압 검사기(510), 풀 브릿지 컨버터 및 PWM(펄스폭 변조; pulse-width modulation) 컨트롤러(520), 고주파 변압기(530), 저주파 필터(540), 과전류 센서(550) 및 피드백 회로(560)를 포함할 수 있다.The high voltage low frequency inverter circuit 500 includes, for example, a voltage checker 510, a full bridge converter, and a pulse-width modulation (PWM) controller 520, a high frequency transformer 530, and a low frequency filter 540. , And an overcurrent sensor 550 and a feedback circuit 560.
전압 검사기(510)는 전원 장치(200)와 풀 브릿지 컨버터 및 PWM 제어기(520) 사이에 위치하여, 풀 브릿지 컨버터 및 PWM 컨트롤러(520)로 입력되는 전압을 감지하여 PWM 컨트롤러(520)에서 일정한 전압을 유지하도록 제어하게 하기 위해 구성될 수 있다.The voltage checker 510 is located between the power supply 200 and the full bridge converter and the PWM controller 520, detects the voltage input to the full bridge converter and the PWM controller 520, and the constant voltage from the PWM controller 520 It can be configured to control to maintain.
또한, 저주파 필터(540)와 방전체(400) 사이에는 과전류 센서(550)가 위치하여, 방전체(400)에서 과전류가 발생하는 경우 이를 감지하여 컨트롤 패널(100)에서 방전체(400)로 흐르는 전류를 즉시 차단할 수 있다.In addition, an overcurrent sensor 550 is positioned between the low-frequency filter 540 and the discharge body 400 to detect when an overcurrent occurs in the discharge body 400 to detect the overcurrent from the control panel 100 to the discharge body 400. The flowing current can be cut off immediately.
도 3은 본 발명의 실시예에 따른 고압 저주파 인버터 회로(500)의 풀브릿지 컨버터의 회로도이고, 도 2는 도 3의 회로에서 형성되는 신호의 파형을 도시하고 있다.3 is a circuit diagram of a full-bridge converter of the high-voltage low-frequency inverter circuit 500 according to an embodiment of the present invention, and FIG. 2 shows a waveform of a signal formed in the circuit of FIG. 3.
도 3에 도시된 회로인 풀브릿지 컨버터는 PWM 컨트롤러(미도시)에 의하여 제어된다.The full-bridge converter, which is the circuit shown in FIG. 3, is controlled by a PWM controller (not shown).
도 3에 도시된 회로에서 G1, G4의 스위치와, G2, G3의 스위치가 교대로 ON/ OFF 되면, 도 2의 첫번째 그래프 및 두번째 그래프와 같은 파형의 신호가 형성될 수 있다.In the circuit shown in FIG. 3, when the switches of G1 and G4 and the switches of G2 and G3 are alternately turned ON/OFF, signals of waveforms such as the first graph and the second graph of FIG. 2 may be formed.
이와 같은 두개의 파형의 신호는 각각 도 3의 D1, D2의 다이오드를 지나 합성되어 도 2의 세번째 그래프의 파형의 신호가 될 수 있다.The signals of these two waveforms may be synthesized by passing through the diodes of D1 and D2 of FIG. 3, respectively, and become signals of the waveform of the third graph of FIG.
이와 관련하여 예를 들면, G1 및 G4가 ON이 되었을 때의 첫번째 그래프의 ON 상태는 두번째 그래프의 파형에서는 OFF 상태가 되며, 첫번째 그래프와 두번째 그래프는 서로 극성이 달라서 D1, D2의 다이오드를 지난후 합쳐지는 경우 세번째 그래프와 같은 PWM 파형을 갖는 신호가 될 수 있다.In this regard, for example, when the G1 and G4 are ON, the ON state of the first graph becomes OFF in the waveform of the second graph, and the first graph and the second graph have different polarities, so after passing the diodes of D1 and D2 When combined, it may be a signal having a PWM waveform as in the third graph.
보다 상세하게, 세번째 그래프는, 40KHz와 같은 고주파 PWM 파형 신호에 저주파 신호(점선)가 합쳐진 형태의 합성 파형 신호에 해당된다.More specifically, the third graph corresponds to a synthesized waveform signal in which a low frequency signal (dotted line) is combined with a high frequency PWM waveform signal such as 40KHz.
40KHz의 고주파와 저주파가 합쳐진 합성 파형은 고주파 파형이므로, 고주파 변압기(530)를 통해 증폭될 수 있다. 이와 같이 고주파 변압기(530)에 의하여 증폭된 합성 파형은 저주파 필터(540)를 통과하여 실질적으로 저주파만이 추출된다. 이와 같이 추출된 저주파 신호는 방전체(400)에 공급되어, 방전체(400)를 통해 저주파 전자기장이 이의 주변으로 방전되고, 이로 인해 저주파 전자기장이 형성될 수 있게 된다.Since the synthesized waveform in which 40KHz high frequency and low frequency are combined is a high frequency waveform, it can be amplified through the high frequency transformer 530. The synthesized waveform amplified by the high-frequency transformer 530 passes through the low-frequency filter 540 to extract substantially only the low-frequency. The low-frequency signal thus extracted is supplied to the discharge body 400, so that the low-frequency electromagnetic field is discharged to its surroundings through the discharge body 400, and thereby, a low-frequency electromagnetic field can be formed.
저주파 전자기장을 형성하기 위하여 단순히 저주파 변압기를 사용하는 경우, 부피와 무게가 커서 관리 및 보관이 어려운 문제점이 있었다. 반면에, 본 실시예에서는, 합성파 생성 회로인 풀브릿지 컨버터 및 PWM 컨트롤러(520)에서 고주파 파형에 저주파를 실은 합성파를 형성하고, 이와 같이 합성파가 형성됨으로써 고주파 변압기(530)를 사용할 수 있으므로, 부피와 무게를 적게 차지할 수 있게 된다. 이에 대해, 저주파 변압기를 사용하는 경우와 비교하여, 대략 수십배 만큼 작게 만들 수 있다.When a low-frequency transformer is simply used to form a low-frequency electromagnetic field, there is a problem in that it is difficult to manage and store due to its large volume and weight. On the other hand, in the present embodiment, the full-wave converter and the PWM controller 520, which are synthesized wave generation circuits, form a synthesized wave carrying a low frequency on a high-frequency waveform, and thus the synthesized wave is formed to use the high-frequency transformer 530. Therefore, it can occupy less volume and weight. On the other hand, compared with the case of using a low frequency transformer, it can be made as small as several tens of times.
한편, 본 실시예에서는, 다수의 고압 저주파 인버터 회로(500) 및 이들 각각에 대응되는 다수의 방전체(400)를 설치하여 다채널을 통해 저주파를 방전하도록 구성될 수 있다.Meanwhile, in the present embodiment, a plurality of high-voltage low-frequency inverter circuits 500 and a plurality of discharge bodies 400 corresponding to each of them may be installed to be configured to discharge low frequencies through multiple channels.
이와 같이, 다채널을 통해 방전체(400)를 여러개 설치하여 다채널에서 저주파 파장들이 발생하는 경우, 파장들의 위상이 서로 동기화되지 않으면 서로 간의 간섭으로 인하여 상쇄되거나 왜곡되는 등 기능이 상실되는 상황이 발생할 수 있다.As described above, when multiple discharge bodies 400 are installed through multi-channels to generate low-frequency wavelengths in the multi-channels, when the phases of the wavelengths are not synchronized with each other, there is a situation in which functions such as offset or distortion due to interference between each other are lost. Can occur.
따라서, 본 실시예에서는, 컨트롤 패널(100)이 유무선 통신 동기화 기능(110)을 구비하도록 하여, 다채널에서 발생하는 저주파 위상을 조정할 수 있다.Therefore, in the present embodiment, the control panel 100 is provided with a wired/wireless communication synchronization function 110, so that the low-frequency phase occurring in multiple channels can be adjusted.
이와 관련하여 예를 들면, 도 4에 도시된 것과 같이, 다수의 고압 저주파 인버터 회로 중 하나를 마스터로 설정하고 나머지 고압 저주파 인버터 회로는 마스터로 설정된 회로에 맞추어 파장의 위상을 조정하여 서로 간의 간섭이 발생하지 않도록 할 수 있다.In this regard, for example, as illustrated in FIG. 4, one of a plurality of high-voltage low-frequency inverter circuits is set as a master, and the other high-voltage low-frequency inverter circuits adjust the phase of the wavelength according to the circuit set as a master, thereby causing interference between each other. It can be prevented from occurring.
예를 들어, 다수의 방전체가 하나의 냉동고의 여러 위치에 설치되는 경우, 위치에 따라 각각의 방전체에서 방전된 파장의 위상을 서로 다르게 설정하는 것이 바람직할 수 있다.For example, when a plurality of discharge bodies are installed at various positions of one freezer, it may be desirable to set the phase of the wavelength discharged from each discharge body differently depending on the location.
따라서, 다수의 고압 저주파 인버터 회로 중 하나를 마스터로 설정한 후, 나머지 고압 저주파 인버터 회로는 방전체의 위치에 따라 위상을 다르게 하는 것이 바람직다. 이에 대해, 도 4에 도시된 것처럼, 나머지 고압 저주파 인버터 회로에 대해, 일부는 π/2만큼 다른 일부는 π만큼 위상 변화(또는 지연)하는 것이 바람직하다.Therefore, after setting one of the plurality of high-voltage low-frequency inverter circuits as a master, it is preferable that the remaining high-voltage low-frequency inverter circuits have different phases depending on the position of the discharge body. On the other hand, as shown in Fig. 4, for the remaining high-voltage low-frequency inverter circuit, it is desirable to change the phase (or delay) of part by π/2 and π by some.
마스터 회로에서 발생하는 파장에 비하여 π만큼 위상을 바꾸는 고압 저주파 인버터 회로의 방전체는, 마스터 회로의 방전체와 반대에 위치하는 것일 수 있다.The discharge body of the high-voltage low-frequency inverter circuit that changes phase by π compared to the wavelength generated in the master circuit may be located opposite to the discharge body of the master circuit.
이와 같이, 컨트롤 패널에는 다수의 방전체에서 발생하는 저주파 파장의 위상을 조절할 수 있는 기능을 구비할 수 있어, 다수의 방전체에서 발생하는 파장들이 서로 왜곡되거나 상쇄되는 것을 방지할 수 있다.In this way, the control panel may be provided with a function for adjusting the phase of the low-frequency wavelengths generated by a plurality of discharge bodies, and it is possible to prevent the wavelengths generated by the plurality of discharge bodies from being distorted or canceled from each other.
도 5는 도 1의 저주파 전자기장 발생 장치를 복수개 포함하는 소위 저주파 전자기장 발생 시스템을 도시하고 있다.FIG. 5 shows a so-called low-frequency electromagnetic field generating system including a plurality of low-frequency electromagnetic field generating devices of FIG. 1.
이와 같이 저주파 전자기장 발생 장치를 복수개 설치하는 경우에는, 동기화 및 통신에 의하여 복수개의 장치를 동기화 하는 것이 바람직하고, 과전류 센서는 작동 상태를 원격지에서 감시 및 제어하는 것이 바람직하다.When a plurality of low-frequency electromagnetic field generating devices are installed in this way, it is preferable to synchronize the plurality of devices by synchronization and communication, and it is preferable that the overcurrent sensor monitors and controls the operating state at a remote location.
한편, 본 실시예에서 저주파 전자기장을 방전하는 방전체는 다양한 형태로 구성될 수 있는데, 이에 대해 이하에서 보다 상세하게 설명한다.On the other hand, the discharge body for discharging the low-frequency electromagnetic field in this embodiment may be configured in various forms, which will be described in more detail below.
도 6은 본 발명의 실시예에 따른 방전체의 일예를 개략적으로 도시한 도면이다.6 is a view schematically showing an example of a discharge body according to an embodiment of the present invention.
도 6을 참조하면, 본 발명의 방전체(400)는, 적어도 하나의 피복 전선 타입 방전부재(400a)로 구성될 수 있다. 여기서, 다수의 피복 전선 타입 방전부재(400a)가 사용되는 경우에, 이들은 직렬 및/또는 병렬로 연결될 수 있으며, 도 6에는 직렬 연결된 경우의 예를 도시하고 있다.Referring to FIG. 6, the discharge body 400 of the present invention may be composed of at least one coated wire type discharge member 400a. Here, when a plurality of covered wire type discharge members 400a are used, they may be connected in series and/or in parallel, and FIG. 6 shows an example of a series connection.
피복 전선 타입 방전부재(400a)는, 저주파 신호가 인가되어 저주파를 방전하는 도전성의 전선(401)과, 이 전선(401)을 둘러싸 전기적으로 절연하는 절연피복재(402)으로 구성될 수 있다. The coated electric wire type discharge member 400a may be formed of a conductive electric wire 401 for discharging a low frequency by applying a low frequency signal, and an insulating coating 402 surrounding the electric wire 401 and electrically insulating it.
한편, 다수의 방전부재(400a)가 사용되는 경우에, 이웃한 방전부재(400a) 사이에는 이들을 전기적으로 접속하기 위한 연결전선(450)이 배치될 수 있다.Meanwhile, when a plurality of discharge members 400a are used, a connecting wire 450 for electrically connecting them between neighboring discharge members 400a may be disposed.
이와 같은 피복 전선 타입 방전부재(400a)는, 저주파 전자기장 발생 장치가 적용되는 냉장고 등의 장비나 설비에 대해 사용자가 원하는 구조나 형태에 부합하도록 설치될 수 있는 장점이 있다. 따라서, 방전체(400)의 설치 자유도가 극대화될 수 있게 된다.The coated wire type discharge member 400a has an advantage in that it can be installed to conform to a structure or shape desired by a user for equipment or equipment such as a refrigerator to which a low-frequency electromagnetic field generating device is applied. Therefore, the degree of freedom of installation of the discharge body 400 can be maximized.
