[ detailed description ] embodiments
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 is a schematic view schematically showing a low-frequency electromagnetic field generating apparatus according to an embodiment of the present invention.
According to fig. 1, the low-frequency electromagnetic field generating device includes a control panel (100), a power supply device (200), a high-voltage low-frequency inverter circuit (500), and a discharge body (400).
The low-frequency electromagnetic field generating device (10) of the present embodiment can be applied to various apparatuses (or equipment, facilities) for treating (for example, storing) moisture-containing articles such as foods. In the present embodiment, such a device is referred to as a low-frequency electromagnetic field application device.
As for the low-frequency electromagnetic field applying apparatus as described above, for example, the low-frequency electromagnetic field generating device (10) may be mounted on a food processing apparatus such as a refrigerator, a freezer, a defrosting tank, a heating tank, a dryer, a fryer, or the like, or on a fish tank, a water culture apparatus, or the like. Further, the medical storage apparatus for storing blood or the like may be attached. Can also be installed on sauna bath or other facilities for use as therapeutic equipment.
When the low-frequency electromagnetic field generating device (10) is used for a refrigerator, a freezer and the like, foods stored in the refrigerator are exposed to (or radiated by) a low-frequency electromagnetic field discharged (or radiated) from the low-frequency electromagnetic field generating device (10) to maintain freshness.
The power supply device (200) supplies power to the high-voltage low-frequency inverter circuit (500) of the control panel (100).
On the other hand, a plurality of high-voltage low-frequency inverter circuits (500) and discharge machines (400) can be used in the low-frequency electromagnetic field generating device (10). A power supply device (200) of a control panel (100) is connected in parallel with a plurality of high-voltage low-frequency inverter circuits (500) and discharge bodies (100), and generates a multi-channel low-frequency electromagnetic field by the plurality of discharge bodies (400).
The control panel (100) can adjust the frequency and voltage output by the discharge body (400).
The power supply device (200) is a power supply device, preferably a switch mode power supply device (SMPS) can be used, and a 24-48V power supply for a vehicle or a 110-220V power supply for a household can be converted into a voltage used by the high-voltage low-frequency inverter circuit (500) and a voltage used by the control panel (100).
The power supply device (200) has both AC and DC capabilities and can be powered by a conventional power supply or battery.
The high-voltage low-frequency inverter circuit (500) comprises a voltage detector (510), a full-bridge converter, a PWM (pulse-width modulation) controller (520), a high-frequency transformer (530), a low-frequency filter (540), an overcurrent sensor (550) and a feedback circuit (560).
The voltage detector (510) is located between the power supply device (200) and the full-bridge converter and the PWM controller (520), and senses the voltage input to the full-bridge converter and the PWM controller (520) to control the PWM controller (520) to maintain a constant voltage.
An overcurrent sensor (550) is arranged between the low-frequency filter (540) and the discharge body (400), and when the discharge body (400) has overcurrent, the overcurrent sensor can sense the overcurrent and cut off the current flowing from the control panel (100) to the discharge body (400) in time.
Fig. 3 is a circuit diagram of a full-bridge converter of a high-voltage low-frequency inverter circuit (500) according to an embodiment of the present invention, and fig. 2 is a diagram illustrating signal waveforms formed in the circuit of fig. 3.
The circuit illustrated in fig. 3, i.e. the full bridge converter, is controlled by a PWM controller (not shown).
When the switches G1, G4 and the switches G2, G3 in the circuit illustrated in fig. 3 are alternately turned on and off, the same waveform signals as those of the first pattern and the second pattern of fig. 2 are formed.
The two waveform signals are combined by the diodes D1 and D2 in fig. 3, respectively, to form a waveform signal in the third graph in fig. 2.
In this regard, for example, when G1 and G4 are turned ON, the ON state of the first pattern is turned OFF in the waveform of the second pattern, and the first pattern and the second pattern have different polarities, and when they are combined after passing through the diodes of D1 and D2, they can be signals having the same PWM waveform as the third pattern.
Further specifically, the third pattern corresponds to a synthesized waveform signal in which a low-frequency signal (dotted line) is synthesized on a high-frequency PWM waveform signal such as 40 KHz.
The synthesized waveform of 40KHz synthesized by high frequency and low frequency is a high frequency waveform, and can be amplified by a high frequency transformer (530). The synthesized waveform amplified by the high frequency transformer 530 is passed through a low frequency filter 540, and only a low frequency is extracted. The low-frequency signal thus extracted is input to the discharge body (400), and the low-frequency electromagnetic field is released to the surroundings by the discharge body (400), thereby forming a low-frequency electromagnetic field.
When only a low-frequency transformer is used to form a low-frequency electromagnetic field, the size and weight are large, and the management and storage are difficult. In contrast, in the present embodiment, the synthesized wave generating circuit, i.e., the full-bridge converter and the PWM controller (520), forms the synthesized wave carrying the low frequency on the high frequency waveform, and thus the synthesized wave is formed using the high frequency transformer (530), thereby reducing the volume and weight. And can be reduced by about several tens of times compared to when using a low frequency transformer.
On the other hand, in the present embodiment, after a plurality of high-voltage low-frequency inverter circuits (500) and a plurality of discharge bodies (400) corresponding to these circuits are mounted, low-frequency discharge can be realized by a plurality of channels.
As described above, when a plurality of discharge bodies (400) are mounted in a plurality of channels, if the phases of the wavelengths are not synchronized when a low frequency wavelength occurs in the plurality of channels, the functions such as shift and distortion occur due to the mutual interference.
Therefore, in the present embodiment, the control panel (100) is provided with a wired/wireless communication synchronization function (110), and the phase of the low frequency generated on the multiple channels is adjusted.
In this regard, as shown in fig. 4, one of the high-voltage low-frequency inverter circuits is set as a main circuit, and the other high-voltage low-frequency inverter circuits adjust the wavelength phase according to the circuit set as the main circuit, thereby avoiding interference with each other.
For example, when a plurality of discharge bodies are provided at a plurality of positions in one ice chest, it is preferable that the phases of the wavelengths discharged from the respective discharge bodies are set to be different from each other according to the positions.
Preferably, after one of the plurality of high-voltage low-frequency inverter circuits is set as the main circuit, the remaining high-voltage low-frequency inverter circuits change the phase according to the position of the discharge body. In this regard, as shown in fig. 4, for the remaining high-voltage low-frequency inverter circuits, it is preferable that one part is changed (or delayed) in phase by pi/2 degree and the other part is changed in phase by pi degree.
The discharge of the high voltage, low frequency inverter circuit, which changes phase by a degree of pi, may be located in an opposite position to the discharge of the main circuit compared to the wavelength occurring on the main circuit.
As described above, the control panel may be provided with a function of adjusting the phase of the low-frequency wavelength generated from the plurality of discharge bodies, thereby preventing the wavelengths generated from the plurality of discharge bodies from being distorted or shifted from each other.
FIG. 5 is a diagram illustrating a so-called low-frequency electromagnetic field generating system including a plurality of the low-frequency electromagnetic field generating devices of FIG. 1.
A plurality of low-frequency electromagnetic field generating devices are provided as described above, preferably, the synchronization of the plurality of devices is achieved by synchronization and communication, and the overcurrent sensor is preferably used to remotely monitor and control the operating state.
On the other hand, in the present embodiment, the discharge body for discharging the low-frequency electromagnetic field may be formed in various forms, which will be described in further detail below.
