Description
Technical Field
The invention relates to an electric pad with a grounding regulator and a grounding plate detachably attached to the electric pad, which effectively realizes the attenuation of electromagnetic waves through the grounding plate detachably attached to the electric pad, improves the shielding efficiency of the electromagnetic waves and improves the use environment of the electric pad for users at the same time of having the grounding regulator with a built-in carbon grounding piece.
Background
In general, 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 electromagnetic waves are generated due to a potential difference of the Electric field.
As a method for reducing electromagnetic waves of the electric heating pad, a method of twisting two or more electric conductors together to prevent Attenuation (Attenuation) of a magnetic field or a method of covering the electric heating pad with a shielding film to prevent induction of electromagnetic waves to a human body have been mainly used.
However, since this method is practically impossible to completely block electromagnetic waves of the electric heating pad having a large current capacity, there is a high possibility that the electric heating pad is harmful to the human body by lying or sitting thereon when in use.
Recognizing the above-mentioned problems and in order to solve the problems, korean laid-open patent publication No. 10-2001-0099344 proposes an "automatic ground selection adjuster that forms a virtual ground point on an electric pad". The technical gist thereof relates to a method of detecting Neutral lines (Neutral lines) among AC1 and AC2 lines currently applied by an antenna and controlling and grounding them by a microcomputer, but since a method of detecting and shielding after an AC voltage is applied into a hot wire of an electric pad, if this method is adopted, a user is likely to be exposed to electromagnetic waves or an electric field, and it is required to have a plurality of grounding parts, which is called a main cause of composing a complicated circuit.

In the ground plate 200 of the present invention constructed as above, the connection terminals 230 coupled to the ground plate connection buttons 140 of the electric pad 100 are formed at respective edges as in fig. 2, and the ground plate 200 can be tightly fixed to the upper portion of the electric pad 100 by coupling the ground plate connection buttons 140 with the connection terminals 230. Although the coupling method is not particularly limited, it is preferable that a snap coupling method is adopted in view of easy disassembly.
The ground plate 200 combined with the electric pad 100 absorbs and counteracts electromagnetic waves of a human body and also has a dust collecting function, and the collected electromagnetic waves will function as an electromagnetic wave discharging channel or an electromagnetic wave sensing channel similar to that of the ground regulator 300 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 wire 320 connected to a capacitor, and forms a ground potential circuit driven by the microcomputer M, which shields a ground potential by being connected by a lead between the connector 310 and the power wire 320.
More specifically, as shown in fig. 3 and 5, the ground regulator 300 is additionally provided with: the PCB circuit board 330 applies power to REL1 (332), REL2 (334), REL3 (336), and is composed of a plurality of capacitors and diodes for controlling the flow of the applied current and fixing the direction thereof; a shielding member 340 composed of a plurality of shielding sponges 342 and electrolytic capacitors 344 for shielding electromagnetic waves generated when the power is applied to the PCB 330; a detection relay unit 350 that detects signals of REL1 (332), REL2 (334), and REL3 (336); a ground antenna 360 selectively receiving and shielding the signal of the detection relay unit 350 through the microcomputer 380; the carbon grounding member 370 is selectively connected to the PCB circuit board 330 according to whether or not the electrostatic switch 390 is depressurized, and the bottom surface of the paper-attached electrostatic switch 390 and the bottom surface of the electrostatic switch 390 are spaced apart from each other toward the upper side of the PCB circuit board 330.
A PCB circuit board portion 330 is attached inside the grounding regulator 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 section 330 according to the control signal; the microcomputer 380 stores the voltages in the REL1 (332), REL2 (334), REL3 (336) states detected by the detection relay unit 350 as digitized data signals.
When the surface of the electrostatic switch 390 is depressurized, a current for power supply start-up flows, a ground antenna 360 provided around the ground potential circuit generates a ground potential signal which is transferred to the microcomputer 380 in the process of being depressurized by the detection relay portion 350 being detected as a dc signal, and the ground antenna 360 may include a program designed to drive the REL1 (332) by the microcomputer 380 and connect an ac power supply to the ground potential circuit, detect the ground potential of the ground antenna 360, and when the ground potential signal is detected, sequentially drive the REL2 (334), REL3 (336), and stop and activate the power supply by controlling the recognition program in a place where the ground potential signal is not detected.
The microcomputer 380 may be configured to shield the ground potential at the moment when the power supply is applied in conjunction with the carbon grounding member 370 and the control recognition program, and when the shielding of the ground potential fails, the detection relay unit 350 may detect the signal as a dc signal and reduce the pressure, the signal may be transmitted to the microcomputer 380, and the ground antenna 360 may include a program configured to drive the REL1 (332) by the microcomputer 380, connect the ac power supply 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 REL3 (336), and when the ground potential signal is not detected, stop and activate the power supply by the control recognition program.
The PCB circuit board 330 detects a grounded line among 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, thereby forming an ideal ground state.
The PCB 330 may independently constitute a bypass circuit so that the impedance of AC1 and AC2 supplied to the power supply is the same, and may switch to the triac (TH 2, TH 1), and may switch three states, i.e., REL1 (332), REL2 (334), REL3 (336) at regular intervals in VCC of the microcomputer 380 and sequentially detect them.
The microcomputer 380 converts the voltages based on the 50 to 60Hz electric field into ac, and the voltages detected by the detection relay unit 350 are led from the ground to the ground antenna 360 in the REL1 (332), REL2 (334), REL3 (336) states, and the voltages in the REL1 (332), REL2 (334), REL3 (336) states are stored as digitized data signals, respectively.
Assuming that the lowest value of REL1 (332), REL2 (334), REL3 (336) is selected and VCC is connected to REL1 (332) (TH 2 ON) at the lowest value, TH2 remains ON and TH1 remains OFF. Further, when VCC is connected to REL2 (334), TH2 is kept OFF, TH1 is kept ON, and when VCC is connected to REL3 (336), VCC is kept at the minimum, TH2 and TH1 are both kept ON, thereby realizing sequential detection.
That is, the lowest value (lower value) is found in REL1 (332), REL2 (334), REL3 (336) states so that the ground antenna 360 is grounded to the ground.
Wherein the microcomputer 380 is preferably configured to treat VCC and VSS equally while maintaining a low impedance of VCC and VSS alternating currents. This is to cause the ground antenna 360 to ground the lowest value selected by the microcomputer 380 to the ground.
More specifically, when the surface of the electrostatic switch 390 is depressurized, a current for power supply start-up flows, the ground antenna 360 provided around the ground potential circuit generates a ground potential signal which is transmitted to the microcomputer 380 in the process of being depressurized by the detection relay portion 350 being detected as a direct-current signal, and at the same time, the ground antenna 360 may include a program designed to drive the REL1 (332) through the microcomputer 380 and connect an ac power supply to the ground potential circuit, detect the ground potential of the ground antenna 360, and when the ground potential signal is detected, sequentially drive the REL2 (334), REL3 (336), and stop and activate the power supply by controlling the recognition program where the ground potential signal is not detected.
That is, the ground antenna 360 is configured as: one of REL1 (332), REL2 (334), REL3 (336) is selected by the microcomputer 380, and is alternately connected to VCC through TH1 and TH2, so that the ac power of the power frequency induced by the ground antenna 360 is rectified into dc power in each state, and the voltage value is compared in the ac conversion state of the microcomputer 380, and the microcomputer 380 is connected to VCC through a power line which maintains the lowest value and minimizes the voltage difference from the ground.
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 intensities are 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 transition, so that the electromagnetic wave shielding efficiency can be improved.
The carbon grounding member 370 of the present invention is located on the ceiling side of the bottom surface of the sticker-type electrostatic switch 390 formed outside the grounding regulator 300, i.e., the upper surface of the inside of the grounding regulator 300.
Regarding the carbon grounding member 370, when the user's finger is depressurized by touching the electrostatic switch 390 of the grounding regulator 300, a grounding potential signal is generated, which is detected as a Direct Current (DC) converted signal and transferred to the microcomputer 380.
Accordingly, the ground antenna 360 configured to detect while pressing the electrostatic switch 390 drives REL1 (332) by the microcomputer 380, connects the ac power supply to the ground circuit, measures the ground potential of the ground antenna 360, sequentially drives REL2 (334) and REL3 (336) to identify the ground potential and fix it if the ground potential is not generated, and stops the potential identification process and starts the power supply when the finger is removed from the electrostatic switch 390.
Wherein when the ground potential detection is not completed and the finger is removed from the electrostatic switch 390, the power is not turned on, and the ground antenna 360 may include a program designed as follows: in addition to the initialization, in a state where the power line 320 is connected, the above-described process is omitted and power is directly applied.
The procedure is such that the ground potential signal detecting operation of the ground antenna 360 is performed only in the initial screening process when the power is initially applied, and the power is immediately applied while omitting the ground potential signal detecting operation in a state where the power 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 time when the finger contacts the electrostatic switch 390, and the power should not be turned on when the finger is removed before the detection of the ground potential is completed.
Wherein the process should be repeated until the power is turned on again. And the power supply can be turned on immediately before the power supply is turned off, and the driving of the potential identification program in the above process is omitted.
And when the power line is reinserted after being pulled out, the process is initialized, and the potential identification program is restarted.
In particular, the carbon grounding member 370 is capable of attenuating electromagnetic waves generated from the grounding regulator 300 due to its conductive property, and is capable of releasing most of the electromagnetic waves to the ground surface without affecting the human body due to its organic cooperation with the grounding antenna 360 and the microcomputer 380 during the operation.
In view of the above, the present invention is a technology that can remarkably increase the attenuation efficiency of electromagnetic waves released from an electric pad by attaching a ground plate woven from carbon yarn or the like having excellent conductivity to the electric pad, and a grounding regulator having a carbon grounding member having conductivity is attached to a PCB circuit board with a grounding antenna, thereby further improving the shielding efficiency of electromagnetic waves, safely shielding electromagnetic waves, and providing an electric pad that improves the use environment of users, and thus has a very high industrial utility value.
As described above, although the embodiment of the electric pad with the ground regulator and the ground plate detachably attached to the electric pad of the present invention is described, this is merely an exemplary description of the preferred embodiment of the present invention and is not intended to limit the present invention. And it is apparent that a person of ordinary skill 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.
