Abstract
The present invention relates to an electrical pad having a grounding regulator and a grounding plate detachably attached to the electrical pad, comprising: the electric pad consists of a pad body, a hot wire terminal, a ground plate connecting button, a ground wire and a ground terminal; the grounding plate consists of an inner skin, an outer skin and a connecting terminal; and a ground regulator composed of a connector, a power line, a lead, and a ground potential circuit.
Description
Technical Field
The present invention relates to an electric pad having a ground conditioner and a ground plate detachably attached to the electric pad, which effectively attenuates electromagnetic waves through the ground plate detachably attached to the electric pad, and improves the shielding efficiency of electromagnetic waves and the use environment of the electric pad for a user while having a ground conditioner with a carbon ground member built therein.
Background
Generally, when an ac voltage is applied using an Electric pad, a mutual inductance operation occurs between an Electric field (Electric field) and a Magnetic field (Magnetic field), and an electromagnetic wave is generated due to a potential difference of the Electric field.
As a method for reducing electromagnetic waves of the electric mat, an Attenuation (Attenuation) method of twisting two or more electric conductors together to prevent the generation of a magnetic field, or a shielding film covering the electric conductors to prevent the induction of electromagnetic waves to the human body, is mainly used.
However, since it is practically impossible to completely block electromagnetic waves of the electric mat having a large current capacity, there is a high possibility that the electric mat may have a harmful effect on the human body by lying or sitting on the electric mat when in use.
Recognizing the above-mentioned problem and in order to solve the problem, korean laid-open patent publication No. 10-2001-0099344 proposes "an automatic ground selection regulator that forms a virtual ground point on an electric pad". The technical gist thereof relates to a method of detecting a Neutral line (Neutral line) among currently applied AC1 and AC2 lines through an antenna and controlling and grounding it using a microcomputer, but since a method of detecting and shielding after an alternating voltage is applied into a hot line of an electric mat, if this method is employed, a user is likely to be exposed to an electromagnetic wave or an electric field, and it is required to have a plurality of grounding parts, which is called a main reason for constituting a complicated circuit.

The ground plate 200 is dyed with one of RED (RED), GREEN (GREEN), and BLUE (BLUE) or a combination thereof, thereby providing aesthetic appearance to a user.
In the ground plate 200 of the present invention constructed as above, the connection terminals 230 of the ground plate connection buttons 140 coupled to the electrical pad 100 are formed at respective edges as shown in fig. 2, and the ground plate 200 can be closely fixed to the upper portion of the electrical pad 100 by the coupling of the ground plate connection buttons 140 and the connection terminals 230. Although the coupling method is not particularly limited, it is preferable that a snap coupling method is used in consideration of easy detachment.
The ground plate 200 combined with the electric pad 100 absorbs and cancels the electromagnetic waves of the human body and has a dust collecting function, and the collected electromagnetic waves will function like an electromagnetic wave discharging path or an electromagnetic wave sensing path moving to the grounding regulator 300, which will be described later.
In the structure of the present invention, the ground regulator 300 includes a connector 310 detachably coupled to the hot wire terminal 130 and the ground terminal 160 of the electric pad 100, a power line 320 connected to the capacitor, and forms a ground potential circuit driven by the microcomputer M, which is connected between the connector 310 and the power line 320 by a wire, shielding the ground potential.
More specifically, as shown in fig. 3 and 5, the grounding adjuster 300 is attached with: a PCB circuit board section 330 configured to apply power to REL1 (332), REL2 (334), and REL3 (336), respectively, and to include a plurality of capacitors and diodes whose directions are fixed by controlling the flow of applied current; a shield 340 composed of a plurality of shield sponges 342 and an electrolytic capacitor 344, for shielding electromagnetic waves generated when power is applied to the PCB circuit board 330; a detection relay unit 350 that detects signals of the REL1 (332), REL2 (334), and REL3 (336); a ground antenna 360 for selectively receiving and shielding the signal of the detection relay unit 350 through the microcomputer 380; the carbon ground member 370 is positioned outside the ground controller 300, and is selectively connected to the PCB circuit board 330 depending on whether the electrostatic switch 390 is depressurized, and a bottom surface of the electrostatic switch 390 is spaced apart from an upper side of the PCB circuit board 330.
A PCB circuit board portion 330 is attached to the inside of the ground adjuster 300 of the present invention, and the PCB circuit board portion 330 includes: a ground antenna 360 for screening and shielding the ground potential outputted from the PCB circuit board part 330 according to the control signal; the microcomputer 380 stores the voltages detected by the detection relay unit 350 in the state of REL1 (332), REL2 (334), and REL3 (336) as digitized data signals.
When the surface of the electrostatic switch 390 is depressurized, a current for power supply activation flows, and a ground potential signal is generated by a ground antenna 360 provided around a ground potential circuit, and the ground potential signal is transmitted to a microcomputer 380 in a process of being depressurized by being detected as a dc signal by the detection relay unit 350, and the ground antenna 360 may include a program designed to drive the REL1 (332) and connect an ac power source to the ground potential circuit by the microcomputer 380, detect the ground potential of the ground antenna 360, and drive the REL2 (334) and REL3 (336) in sequence when the ground potential signal is detected, and stop and activate the power supply by controlling a recognition program at a place where the ground potential signal is not detected.
The microcomputer 380 shields the ground potential at the moment when the power is applied in conjunction with the carbon ground 370 and the control recognition program, and when the shielding of the ground potential fails, the signal is transmitted to the microcomputer 380 while the detection relay unit 350 detects a direct current signal and reduces the voltage, and the ground antenna 360 may include a program designed to drive the REL1 (332) by the microcomputer 380, connect an alternating current power source to the ground potential circuit, measure the ground potential of the ground antenna 360, and when the ground potential signal is detected, sequentially drive the REL2 (334) and the REL3 (336), and stop and activate the power supply by the control recognition program at a place where the ground potential signal is not detected.
The PCB board part 330 detects a grounded line among the 110V and 220V/50Hz power lines for home use, and if the grounded line is not detected, a virtual neutral ground circuit is generated inside the ground regulator 300, so that the ground antenna 360 is grounded to the ground surface, resulting in an ideal ground state.
The PCB board 330 may independently form a bypass circuit such that the impedances of the AC1 and AC2 supplied with power are the same, and may be switched to the triacs (TH 2, TH 1) to switch three states, that is, REL1 (332), REL2 (334), and REL3 (336), at regular time intervals in the VCC of the microcomputer 380 and sequentially detect them.
The microcomputer 380 converts a voltage based on an electric field of 50 to 60Hz into an alternating current, and then leads the voltage in the state of REL1 (332), REL2 (334), and REL3 (336) detected by the detection relay unit 350 from the ground surface to the ground antenna 360, and stores the voltages in the states of REL1 (332), REL2 (334), and REL3 (336) as digital data signals.
If the lowest value is selected among the REL1 (332), REL2 (334), and REL3 (336) states and VCC is the lowest value when it is connected to REL1 (332) (TH 2 ON), TH2 is kept ON and TH1 is kept OFF. Further, if VCC is connected to REL2 (334), TH2 is kept OFF and TH1 is kept ON, and if VCC is connected to REL3 (336), both TH2 and TH1 are kept ON, thereby realizing sequential detection.
That is, the lowest value (lower value) is found among the REL1 (332), REL2 (334), REL3 (336) states, so that the ground antenna 360 is grounded to the ground surface.
Preferably, the microcomputer 380 is configured to treat VCC and VSS equally while maintaining low impedance for VCC and VSS. This is for the grounding antenna 360 to ground the lowest value selected by the microcomputer 380 to the ground surface.
More specifically, when the surface of the electrostatic switch 390 is depressurized, a current for power supply activation flows, and a ground potential signal is generated by a ground antenna 360 provided around a ground potential circuit, and the ground potential signal is transmitted to the microcomputer 380 in the process of being depressurized by being detected as a dc signal by the detection relay unit 350, and the ground antenna 360 may include a program designed to drive the REL1 (332) and connect an ac power supply to the ground potential circuit by the microcomputer 380, detect the ground potential of the ground antenna 360, and drive the REL2 (334) and REL3 (336) in sequence when the ground potential signal is detected, and stop and activate the power supply by controlling a recognition program where the ground potential signal is not detected.
That is, the ground antenna 360 is configured to: one of REL1 (332), REL2 (334), REL3 (336) is selected by the microcomputer 380, alternately connected to VCC through TH1 and TH2, and in each state, the alternating current of the power frequency induced by the grounding antenna 360 is rectified into direct current, and in the alternating current conversion state of the microcomputer 380, the voltage values are compared, and the lowest value is maintained and the microcomputer 380 is caused to connect the power supply line having the smallest voltage difference with the earth surface to VCC.
Therefore, by the structure of the ground antenna 360 and the microcomputer 380, three kinds of data are sequentially detected when the power is connected, the electric field intensity is stored and compared in each state, the data value in the lowest state is selected, and the lowest electric field can be continuously selected without state conversion, thereby improving the shielding efficiency of the electromagnetic wave.
The carbon ground 370 of the present invention is located on the bottom surface of the electrostatic paper-stuck switch 390 formed outside the ground regulator 300, i.e., the ceiling side of the upper inside of the ground regulator 300.
As for the carbon ground 370, when a user's finger is brought into contact with the electrostatic switch 390 of the ground regulator 300 to be depressurized, a ground potential signal is generated, which is detected as a Direct Current (DC) signal and transmitted to the microcomputer 380.
Therefore, the ground antenna 360 configured to detect while holding the electrostatic switch 390 is driven by the microcomputer 380, REL1 (332) is connected to the ac power supply to the ground circuit, the ground potential of the ground antenna 360 is measured, and if the ground potential is not generated, REL2 (334) and REL3 (336) are sequentially driven to identify the ground potential and fix it, and when the finger is removed from the electrostatic switch 390, the potential identification program is stopped and the power supply is started.
When the ground potential detection is not completed, the finger is removed from the electrostatic switch 390, and the power supply is not turned on, and the ground antenna 360 may include a program designed as follows: in a state where the power supply line 320 is connected, the above-described process is omitted and power is directly applied, except for initialization.
The program causes the ground potential signal detection operation of the ground antenna 360 to be performed only in the initial screening process when power is initially applied, omitting the ground potential signal detection operation and immediately applying power in a state where the power supply line 320 of the ground regulator 300 is always connected to the capacitor.
Also, the ground antenna 360 may include a program designed as follows: during the period when the ground potential signal has not been detected and the electrostatic switch 390 is changed from the depressurized state to the non-depressurized state, the power supply is not activated.
That is, the power should not be turned on during the finger contact with the electrostatic switch 390, and when the finger is removed before the detection of the ground potential is completed, the power should not be turned on.
Wherein the process should be repeated until the power is turned on again. And the power supply can be immediately turned on before the power supply is turned off, and the driving of the potential recognition program in the above process is omitted.
And when the power line is pulled out and then inserted again, the process is initialized, and the potential recognition program is restarted.
In particular, the carbon ground member 370 can attenuate electromagnetic waves generated from the ground regulator 300 due to its conductive property during the operation, and can release most of the electromagnetic waves to the ground surface without affecting the human body due to its organically cooperative work with the ground antenna 360 and the microcomputer 380.
In summary, the present invention is a technique that attaches a ground plate woven from carbon yarn or the like having excellent conductivity to an electric pad, which can significantly increase the attenuation efficiency of electromagnetic waves emitted from the electric pad, and a ground adjuster having a carbon ground member having conductive properties and a ground antenna attached to a PCB circuit board, thereby further improving the shielding efficiency of electromagnetic waves, safely shielding electromagnetic waves, and improving the environment in which a user uses the electric pad, which is a technique having a very high industrial utility value.
As described above, although the embodiment of the present invention having the electric pad of the ground regulator and the ground plate detachably attached to the electric pad is described, this merely illustrates the preferred embodiment of the present invention and does not limit the present invention. It is apparent that those skilled in the art of the present invention can implement various modifications and simulations without departing from the scope of the technical idea of the present invention.
