Description

Electromagnetic wave energy harvesting module and four-season earthing mat including the same

[0001] The present application relates to an electromagnetic wave energy harvesting module and a four-season earthing mat including the same, and more specifically, to an electromagnetic wave energy harvesting module with improved harvesting efficiency, and an electromagnetic wave harvesting four-season earthing mat that improves the health of a user by making the user's body electrically neutral by absorbing and blocking electromagnetic waves generated from the mat.

[0002] With fossil fuels depleting, extensive research is being conducted to develop alternative energy sources. Currently, promising alternative energy sources include nuclear energy, solar energy, wind energy, and tidal energy. Nuclear energy suffers from the enormous costs of radioactive waste disposal and nuclear power plant construction. Solar energy's power generation efficiency often falls short of the investment costs. Wind and tidal energy suffer from the limited potential for power plant installation.

[0003] As an alternative, research is actively being conducted to utilize electromagnetic waves generated from various electronic devices, such as TVs and computers, as an energy source, such as induction generators using electromagnetic waves, as disclosed in Korean Patent Publication No. 10-2011-0003455.

[0004] Meanwhile, a heated mat is a mat that supplies heat by supplying current to wires placed inside the mat.

[0005] Among heated mats, hot water mats are products that generate heating effects by circulating hot water inside the mat rather than using electric wires. Compared to electric blankets, they have advantages such as electromagnetic wave and fire prevention and low power consumption, and their sales have increased significantly since 2013. Among heated mats, electric mats are also seeing an increase in sales.

[0006] Accordingly, various types of thermal mats with high efficiency are being developed.

[0007] For example, according to Republic of Korea Utility Model Registration No. 20-0436884, a heating mat is disclosed that has the dual effect of increasing work efficiency by forming a protrusion integrally with a fixed passage for inserting a hot water pipe, thereby preventing the hot water pipe from coming off during the work process, and reducing costs by not using separate materials that may cause defects in the product.

[0046]

[0047] FIG. 1 is a circuit diagram for explaining an electromagnetic wave energy harvesting module according to an embodiment of the present application.

[0048] Referring to FIG. 1, an electromagnetic wave energy harvesting module according to an embodiment of the present application includes an antenna (At), a rectifier (D1 to D4), a first inductor (L1), a second inductor (L2), a ground (G1, G2), first to sixth switches (S1 to S6), a first capacitor (C1), a first resistor (R1), a second resistor (R2), an operational amplifier (OP), a fifth diode (D5), and an alternating current output (V AC ) may be included.

[0049] The above antenna (At) can generate a surface alternating current by using electromagnetic waves transmitted to the outside.

[0050] The surface alternating current generated by the above antenna (At) can be transmitted to the first point (P1).

[0051] One end of the first inductor (L1) may be connected to the first point (P1), so that the surface alternating current may be transmitted to the first inductor (L1). The other end of the first inductor (L1) may be connected to the second point (P2).

More specifically, the grounding portions (G1, G2) can include a first grounding portion (G1) connected to the ground, and a second grounding portion (G2) including a neutral wire or a metal plate, and as described below, the first switch (S1) can be controlled to connect either the first grounding portion (G1) or the second grounding portion (G2) to the second switch (S2) and the third switch (S3).

[0054] The second switch (S2) can be controlled to connect the second point (P2) and the fourth point (P4), or the second point (P2) and the first switch (S1) can be controlled to connect.

[0055] One end (the third point (P3)) of the above rectifier (D1 to D4) can be connected to one end of the second inductor (L2).

[0057] The above rectifier (D1 to D4) may include a first diode (D1) to a fourth diode (D4).

[0058] The above first diode (D1) may have an anode and a cathode that are connected to one end of the above second inductor (L2) and constitute one end (the third point (P3)) of the above rectifier (D1 to D4).

[0059] The second diode (D2) may include a cathode connected to the cathode of the first diode (D1), and an anode constituting the other end of the rectifier (D1 to D4) (the sixth point (P6)).

[0060] The third diode (D3) may include a cathode and an anode connected to the anode of the first diode (D1) and forming one end (the third point (P3)) of the rectifier (D1 to D4).

[0061] The fourth diode (D4) may include an anode connected to the anode of the third diode (D3), and a cathode that constitutes the other end (the sixth point (P6)) of the rectifier (D1 to D4) and is connected to the anode of the second diode (D2).

[0062] The above rectifiers (D1 to D4) may include a fifth point (P5) and a seventh point (P7), and the current rectified in the rectifiers (D1 to D4) may be output through the fifth point (P5) and the seventh point (P7).

[0063] One end of the first capacitor (C1) can be connected to the fifth point (P5), and the other end of the first capacitor (C1) can be connected to the seventh point (P7).

[0064] The fourth switch (S4) can be controlled to connect the fifth point (P5) and the first output terminal (O1), or to connect the fifth point (P5) and the tenth point (P10).

[0065] The above fifth switch (S5) can control the seventh point (P7) and the second output terminal (O2) to be connected, or can control the seventh point (P7) and the eleventh point (P11) to be connected.

[0066] The above sixth switch (S6) can control whether the fifth point (P5) and the eighth point (P8) are connected.

[0067] The fifth diode (D5) may be a Zener diode and include a cathode connected to the tenth point (P10) and an anode connected to the eleventh point (P11).

[0068] The first resistor (R1) may include one end connected to the eighth point (P8) and the other end connected to the ninth point (P9), and the second resistor (R2) may include one end connected to the other end of the first resistor (R1) (the ninth point (P9)) and the other end connected to the sixth point (P6).

[0069] The V+ of the above OP amplifier (OP) is connected to the 10th point (P10), the V- is connected to the 11th point (P11), the 9th point (P9) and the 11th point (P11) are input, and the output terminal of the OP amplifier (OP) can form the third output terminal (O3).

[0070] The fourth output terminal (O4) can be connected to the sixth point (P6).

[0071] According to an embodiment of the present application, as described below, depending on the operation of the first to sixth switches (S1 to S6), a DC plus high voltage and a DC minus high voltage can be output from the first output terminal (O1) and the second output terminal (O2), respectively, and a DC plus constant voltage and a DC minus constant voltage can be output from the third output terminal (O3) and the fourth output terminal (O4), respectively.

[0072] In the electromagnetic wave energy harvesting module according to the embodiment of the present application, the first and second inductors (L1, L2) can improve the power factor by using an inductor that is a (leading) lag gate, since the power collected through harvesting becomes reactive power, and can change it into active power, and at the same time, by operating a switch, power factor compensation and voltage control are possible at the same time.

[0073] Electromagnetic waves generated from power lines, power sources, and power supplies generate surface alternating currents using metal. This is similar to the inflow of power due to capacitance generated between the wire and the metal. Because this inflow of power passes through a capacitive load, it is 100% reactive power, specifically, true power. Even if power is obtained using grounding, it is reactive power and therefore not easily usable.

[0074] When the leading power is transferred to the ground power, active power is generated. The method for obtaining active power is to add an inductor component or convert it into direct current. However, when the leading component is directly converted to direct current using a rectifier circuit, the efficiency is reduced due to the threshold voltage and pulsation, and the efficiency is lowered.

[0075] Therefore, by using a switch, it is possible to transform the inductor component by allowing it to pass through, or in some cases, by adjusting the voltage while simultaneously allowing it to pass through, and then converting the effective power into direct current. The direct current can be used as high-voltage power as is, or it can be output as a constant voltage using an op-amp. The selection between high voltage and constant voltage can be controlled through a switch.

[0076] According to the embodiment of the present application, it is easy to make 100% of the reactive power into an active power close to 100%, so that power can be harvested and used more efficiently. In addition, when only a Zener diode was used, there were cases where the constant voltage was not properly output and the efficiency was reduced, but a more efficient constant voltage can be generated by using an OP amplifier.

In addition, electromagnetic waves may be generated in the first heating wire (110) by the direction in which the coil-shaped first heating wire (110) is wound and the direction of the first current (I1).

[0122] According to one embodiment, the first heating wire (110) may be provided in the form of a line extending in one direction, rather than in the form of a coil, as shown in FIG. 2.

[0123] Additionally, according to one embodiment, the first heating wire (110) may be provided in multiple numbers.

[0124] The first insulating layer (112) can surround the first heating wire (110). The first insulating layer (112) can be formed of various insulating materials. For example, the first insulating layer (112) can be formed of silicone, Teflon, PVC, etc.

[0125] The second heating wire (120) may be provided in the form of a coil that wraps around the first insulating layer (112). A second current (I2) may flow through the second heating wire (120). The second current (I2) flowing through the second heating wire (120) and the first current (110) flowing through the first heating wire (110) may flow in opposite directions.

[0126] According to one embodiment, one end of the first heating wire (110) and one end of the second heating wire (120) may be connected to each other. Specifically, the first current (I1) may flow into the first end of the first heating wire (110), a heating current (the first current (I1)) may flow from the first end of the first heating wire (110) to the second end of the first heating wire (110), and the heating current (the second current (I2)) may flow into the first end of the second heating wire (120) connected to the second end of the first heating wire (110), and the heating current (the second current (I2)) may flow from the first end of the second heating wire (120) to the second end of the second heating wire (120). In this case, the first current (I1) and the second current (I2) may be the same current. In addition, the first end of the first heating wire (110) and the second end of the second heating wire (120) may be connected to a power supply unit for supplying the heating current to the heating wires (110, 120).

[0127] Alternatively, according to another embodiment, the first heating wire (110) and the second heating wire (120) may be provided in an electrically separated state.

[0128] As described above, electromagnetic waves may be generated in the first heating wire (110) depending on the direction in which the first heating wire (110) in the coil shape is wound and the direction of the first current (I1). In addition, electromagnetic waves may be generated in the second heating wire (120) depending on the direction in which the second heating wire (120) in the coil shape is wound and the direction of the second current (I2). The twisting directions of the first heating wire (110) and the second heating wire (120) may be the same, and the directions of the first current (I1) and the second current (I2) may be antiparallel to each other. Accordingly, the phase difference between the electromagnetic waves generated from the first heating wire (110) and the electromagnetic waves generated from the second heating wire (120) may be 180°, and the electromagnetic waves generated from the first heating wire (110) and the electromagnetic waves generated from the second heating wire (120) may cancel and interfere with each other. Accordingly, the electromagnetic waves emitted to the outside and introduced into the human body may be minimized.

[0129] The second insulating layer (122) can surround the second heating wire (120). The second insulating layer (122) can be formed of various insulating materials. For example, the second insulating layer (122) can be formed of silicone, Teflon, PVC, etc.

[0130] The above electromagnetic wave absorbing portion (130) can absorb electromagnetic waves generated from the first heating wire (110) and / or the second heating wire (120) and emitted to the outside. The above electromagnetic wave absorbing portion (130) can be provided in the form of a metal foil that wraps the second insulating layer (122).

[0131] The above electromagnetic wave absorbing portion (130) can absorb electromagnetic waves and convert them into alternating current. The alternating current may be a surface current generated when electromagnetic waves contact a conductive object (the electromagnetic wave absorbing portion (130)). The surface current may flow along the surface of the conductive object (the electromagnetic wave absorbing portion (130)).

[0132] The above electromagnetic wave absorbing part (130) can correspond to the antenna (At) described above with reference to FIGS. 1 to 7, and the AC current generated in the above electromagnetic wave absorbing part (130) can be converted into electric energy as described with reference to FIGS. 1 to 7.

Hereinafter, with reference to FIG. 10, a second embodiment of the heat supply pipe included in the electromagnetic wave harvesting four-season earthing mat according to the embodiment of the present invention will be described.
