Description

A Method and system for a safe electricity flow for an 5 electrical devices and systems and for controlling the electricity flow in the wires and reducing electricity radiation and electricity consumption

FIELD of the INVENTION

This invention is in the field of electrical accessories safety equipment and in particular of a method and system for a safe electrical controlling an electricity flow to electrical devices and systems, and for controlling the electricity flow in wires and reducing electricity radiation and consumption. This by controlling the electricity flow, and by enabling absence of the electrical flow current at list in parts of the electricity wires wired between the electricity power source from its connection to the present invention system, to the electrical device or system or sockets, for example, electrical flow current does not flows or flow current reduced significantly for example, current reduced between 1-5 volt, this until the plug of an appliance is inserted into the electric socket or is connected permanently to it and the appliance switch is switched to an on position.

For better understanding of present invention, the present invention does not take the state of existing electricity in wires as necessity and a no other options situation, as the existing situation, that grasp a way of thinking that electricity must flow all time or most time at the wires that are wired from the main electricity source to the wall sockets for example, but, the present invention innovates a condition that allowing electricity to flows in the wires just at a certain situations, for example, when the system has a recognition or identification of a demand for electricity by an appliance.

BACKGROUND of the INVENTION

Safety electricity and reducing electricity radiation and consumption have been a prime concern since electricity was invented.

One of the main danger with electrical devices, electricity wires and electrical sockets are that items can be inserted into the electricity wires or socket holes and the live high electrical current flow and the electricity flows in the wires or socket passes through the inserted object, especially if it is made by a conducting material, or even if a bare part of the human body is in contacts with the wires or with devices connected to wires. In those situations and in others, the electricity passes, for example, through the person body holding the object, and by that, the person body connection with the electricity, closing an electricity circuit with the ground, and electrifies.

Children are particularly vulnerable to this danger, as they like poking things into holes, for example, to wall electrical sockets, even wet fingers. Electricity of 11 OV is dangerous and 220V can be lethal.

There are vast electricity devices and system that operates on an electricity power and force that are dangerous even to a large amount of human safety and for economic assets.

There is a need for eliminating those dangerous, and it is the present invention goal to solve those problems, for example: The friction of electricity wires, for example, in moving objects such as in aircraft and sea vessel systems. Wherein, when the objects are moving objects, the wires are in constant friction one with the others, or even if the connections or part of the wires are coming loose, the remainder of the wires can act as a filament, and act like in a lighting bulbs, by getting heated and causing fires. The present invention eliminates the possible fire danger described herein.

The present invention eliminates the possible fire danger existing in floor heating system. Floor heating system has an electricity wires wired spread under the floor and causes fire dangers.

The present invention eliminates both child and adult possible electrifying from wall sockets and electric extending cables that are connected or not connected to electronic devices and system.

The present invention innovates a new situation, the present invention does not take the state of existing electricity in wires as a necessity or as a no other options situation, as the existing situation before the present invention, that take hold of the way of thinking that electricity must flow all time or most time at the wires that are wired from the main electricity source to the wall sockets for example, other than this, the present invention innovates a new condition that allowing electricity flows in the wires just at a certain particular situations, for example, when recognition or identifying a demand for electricity by an appliance.

Many devices have been revealed in the field of electrical system and devices to make a safe electrical operating of electric devices. This invention is unique in that that at list part of the electrical wires between the electric power source and the electrical consumer or appliance has no electrical current flow in it, for example, one of the preferred embodiments of the present invention, safe electrical socket, the "safe socket", has no electrical current flow to it and in it even when the plug of the appliance is attached to the socket. So if a child were to push, for example, a long metal nail into either side of the empty socket, nothing would happen. Only when the appliance switch is switched on, does the electricity flow loosened from the present invention system that permit it's to flows.

There is a need for electrical system and method that will select and choose from different condition, if to allow electric current to flows through the wires that are between the system of the present invention controlling the electricity from the main source of electricity, for example, and the electric consumer, not allowing the existing situation of all time all wires are to be with electrical current flow. SUMMARY of the INVENTION

It is to be understood that both the foregoing general description and the following detailed description present embodiments of the invention and are intended to provide an overview or framework for understanding the nature and character of the invention as it is claimed.

This invention reveals a method and system, that does not take the state of existing electricity in wires as a necessity and as a must situation, as in the existing condition before the present invention, that grasp that electricity must flow all time or most time at the wires that are wired from the main electricity source to the wall sockets for example, that is to be replaced by the present invention method and system, that innovates a new condition that allowing electricity flows in the wires just at a certain situations, for example, when recognition or identification of a demand for electricity by an appliance is obtains.

This invention reveals a method and system that allows the transfer of the electrical current flow to the electrical wires or appliance, or to at list part of the electrical wires, or to the wall socket, only in defined and certain condition, and not in every time as the wrong existing concept that takes the situation as an unchangeable, for example, only when there is an electrical appliance connected to the wall electric socket and this appliance would be switched to on position does the present invention system will allows the electric flow to the socket or to the electrical appliance. Therefore, the system of the present invention, connecting to the main source of electricity, closing the flow of the electricity current flow to its designating wires, and enabling by turning the operating button of the appliance from off position to on position, to continue the flow of the negative electric flow, that the system didn't close from flowing on from main electricity main source of power, and allowing it to flow in its designated electricity wires, through the appliance inner circuit, and furthermore, to continue and flow through the wires of the electrical current that are empty from electricity, until reaching the present invention system that detect that negative flows, and in some cases consider it as an appliance demand for electricity.

Wherein, the system of the present invention, at that time, closing down the negative flow that is at the wires designated for the electricity current flows, and releases the electricity current flows, enabling the electricity operation needed for electrical appliances.

The invention enabling the electricity behavior in such a way, that:

Whenever a consumer (electrical device that has been operated; an electrical appliance) is detected, just then, the electricity is to be flow in the electricity line; otherwise, no electricity is flowing in that electricity line or electric socket. Whenever an appliance is not detected, the electrical current flow is not allowed to flow in the electricity line. A person who puts his fingers inside the electric socket, for example, is not detected as a customer, and therefore is insured from the natural danger of electrifying. Consumer: E.G. an electrical device, E.G. ventilator, kettle, et cetera.

The system of the present invention connected to the electricity main source of power, including relay and smart electronic chip, the electrical current flow, is connected directly to the system of the present invention, and not to the wires or to the wall socket line or to the wires connected to the electrical appliance, only when the system indicate that their is a real electrical appliance demand, the system relies the electrical current flow to the wall socket or to the wires connected to the electrical appliance.

The negative wires of electricity from the main source of power, is connected directly to the electrical appliance, or to the wall socket or to cable and wires that have an independent free flow to the electrical appliance, whenever its wired to the wall socket for example, and wherein, when ever the electrical appliance turned from off position to on position, its closing the appliance circuit. However, when in the normal situation this will leads both, negative and positive current to operates the electrical appliance, in this situation, it will not, as the electrical current flow is stopped before reaching to the electrical appliance, at the present invention system.

At this state, the negative flow started at the main source of power, throughway the electrical appliance, and will continues throughway the electrical current flow wires, that are empty from electrical current flow, because it has been stopped and directed to the system of the safe electrical operating of the present invention, and continuing until the present invention system.

Whenever, their is a real electrical appliance demand, such as turning it to an on position, the system of the present invention detecting the negative flow coming from the line and cable designated for the positive current, if it has the functions as required, it closing a circuit at the present invention system, and because the system of the present invention is connected directly to the electrical current flow of the main power source, the system will close the negative flow and allowing passes of the electricity current flow and enabling the operating of the electrical appliance.

Objects of this invention is to make electrical wires safe when not in use by preventing live electricity flows in the terminals of the electrical wires unless and until an appliance plug is plugged into the socket and the appliance is switched on. The system may be placed along the electrical wires for example, that are places inside the wall, or for example, in the electricity junction box, so the electrical flow would stop in a distance from the electrical wires that are reachable to users and would not be reachable from the external. For another embodiment, the system might be placed in a small box attached to the internal part of the wires connection, leaving the remaining parts of the wires with no electricity flow when there are no demands for operating electrical appliances.

The system might also be placed in a box connected to the electrical socket from the outside, although is alternative is less safe as the pervious discussed alternatives, it would still prevent the transfer of the electrical current terminal electrical plug and to the appliance connected to that plug. The connection of the appliance plug into the wall socket by itself would not cause to the transfer of the electrical flow. Only by operating the appliance, by switching on its operated button for example, it would cause to the electrical circuit to be close and to the negative electricity flow from the appliance to be transferred to the system that would read the call from the appliance for electrical current and would enable the transfer of electrical flow to the wires or to the wall socket for example, and to the appliance. When the appliance would stop to work the system will automatically closed the transfer of the electrical flow to the socket, leaving the wires or the wall socket and the appliance safe even if the appliance is still connected to the wall socket for example.

other important advantages of the system, besides preventing electrifying and fires, is the fact that the electrical appliances that would stay connected to the wall socket for one example, after being used, would not continue to receive the electrical current as happen today, but it would be as if the plug of the appliance were taken out from the wall socket for example.

This advantage effecting not only on the huge economical saving follows from saving in electricity but and mostly would affect the environment by reducing the electromagnetic field that is released from all the electrical appliance that are left connected to the electrical socket even when not in used.

Unfortunately, most of the population is used to leave most of the electrical appliance connected to the electrical socket when not in use that is way this invention would enable us to continue living in comfort and still helping in keeping our planet safe by taking care of the environment.

Moreover the economical saving that is become possible by that invention is also important especially in countries where the electricity is expensive. At the same time there might also be a possibility of enabling the transfer of an electrical current of only few volts to enable the operation of appliance as TV or Stereo by a remote control, so instead of the transfer of 220 or 110 volt to the appliance there would be the transfer of only 10 volt electrical current for example, so the huge drop in the electrical current that would reach to the electrical socket for example, and to the connected appliance would not affect on all the advantages discussed above, and would still allow us to continue living with our normal and used to comfort.

There are variable devices and systems which the present invention and system are to be applied on, for example: Inside a wall-device, the invention system controls the electricity passage from the line to the electrical socket. It may be both connectable and detachable to the electric socket. It may use as a part of an independent electric cable. It may use as a part of an electric adapter. It may use as a part of a floor heating system, eliminating the possible fire danger that it holds. It may use as a part of the aircraft and sea vessel systems, eliminating friction and varied massive dangers which such systems may hold. It eliminates electricity wire friction danger. It eliminates both child and adult electrifying danger, etc.

Fig 2 shows another embodiment of the system 100 that allows the transfer of an electrical flow to the wires or to the wall socket 120 for example, and only when there is a call or a need from an operated electrical appliance 130 that is connected to the wires or to the wall socket 120, then the system allowing current flow. When the system 100 is placed along the electrical wires that are places inside the wall for example in the electricity junction box 110, the electrical flow would stop in a distance from the wall socket and would not reach 140 to the electrical wall socket 120, leaving the electrical wall socket free from electricity current and therefore safe.

That appliance 130 is connected to the electrical wires or to wall socket 120, but when the appliance is not operated there would be no electrical current arriving to the wires 150 since there would be no electrical flow arriving to the wall socket 120 until there would be a call for electricity by operating the appliance 130 (see Fig 3).

Fig 3 shows the same embodiment of system of the present invention as in Fig 2 but when the appliance 130 is operated. When the appliance 130 is operated there, by switching the on button for example from off position of the button, it would cause to the electrical circuit to be close, and to the negative flow from the appliance to be transferred to the socket 160 and to the system 170 that would read the call from the appliance for an electrical current and would enable the transfer of electrical flow to the wires or wall socket 180 for example, and in a continuation to the appliance 190. When the appliance 130 would stop to work, the system 100 would automatically closed the transfer of the electrical flow to the socket, leaving the wires or the wall socket and the appliance safe from electricity current flows, even if the appliance is still connected to the wall socket (see Fig 2) or even if the system is apart of a portable device such as of an extending electricity cable which the system is at the plug-in of it for example.

Fig 4 shows an external box 200 that includes the system of present invention, this could be apart of extending electricity cable which the system is at the plug-in of it for another example and embodiment of the present invention, that allows the transfer of an electrical flow only when there is a call or a need from an operated electrical appliance. This box 200 could be externally placed on inside a regular wall socket 210, and then, it would prevent the transfer of the electrical follow to the external socket 220 until there is a call from an operated appliance. Although this alternative is less safe then if the device is placed inside the wall as discussed before, it would still prevent the transfer of the electrical current to the terminal electrical plug and to the appliance connected to that plug.

Fig 5 shows an embodiment of the system and its components:

Components C1,R22 to U1,C3 in the order of the schematics are the 5v power supply of the circuit.

Cl is a capacitive impedance in series with R 1,2, 3 and that connects to point A of the circuit, and to the 220vac ,from one side and to point B of the circuit via D 2 to the 220vac return(zero).

The use in a capacitive impedance is for power saving.

In the negative half wave (A is negative than B) the current flows from point B to A via D2, R 1-2-3, Cl and charge Cl.

In the positive half wave (A is positive than B) the current flows from point A to B via Cl, R 1-2-3, Dl, and charge C2.

Zl limits the voltage on C2.

R22 discharge Cl when the circuit is disconnected from mains, for safety. Ul and C3 supply regulated 5vDC from C2 voltage, to the rest of the circuit.

The AC voltage is delivered from point A to point C via relay FSl N. O. (normally open) connection via Nl wire of Ml transformer when the coil of FS 1,CRl is powered. When CRl is not powered a very low voltage will be delivered to point C via FSl N. C. (normally close) connection and voltage divider R4 R5 R6 and U3 is short conducting to point B (220vac return) .

Operation description:

At the initial state controller U5 will output Ov to R23 this will cause triac U2 to discontinue so that the coil CRl of FSl will not be powered.

At the same time controller U5 will output 5v to R24 .this will cause triac U3 to conduct and to a low voltage at R4 R6 junction. This low voltage is delivered to point C (the output) via R5, FSl and Nl.

So there is no 220vac on the output now, only a low ac voltage.

Upon a connection of a current consuming instrument (load) between the output (point C) and the return (point B) current will flow via R5 .this will cause a voltage rise on R5.

The circuit consisting U4-B and R13,14, 15, 16, 17 amplifies the voltage on R5. Rl 1, 12 are supplying a dc working point to the above circuit. At the output of U4-B there will be a voltage that expresses the AC voltage on R5, but because U4 can not supply negative voltage, only the positive part of the wave will appear .So we have here a rectification (like) of the AC voltage. This voltage is filtered by R19, C5 and passes via R21 to pin-6 of the controller (U5).So at pin-6 of the controller there is a DC voltage relative to the AC current via R5 to the load.

According to the above explanation, when current will be drawn from the output (point C), the DC voltage on pin-6 of the controller will rise. At a certain value of that voltage, the controller (U5) will supply 5v on pin-2 to R23.This will cause triac U2 to conduct and power CRl, the coil of relay FSl, that will supply 220vac from the input(point A) to the output(point C).

*1 At that time the controller will supply Ov to R24, to disconnect triac U3 in order to save power. At this moment the current consuming instrument (load) that is connected to the output is supplied with 220vac via Nl and generate an AC voltage on N2.This voltage is amplified by circuit consisting U4-A R7,8,9,10 ( Rl 1, 12 are supplying a dc working point to the above circuit). So at the output of U4-A there will be a voltage that is reflecting the AC current consumption of the load. But only the positive part of that voltage will appear at the output of U4-A because U4 can not supply negative voltage. So we have here a rectification (like) of the AC voltage.

This voltage is filtered by R 18, C4 and passes via R20 to pin- 7 of the controller (U5).So at pin-7 of the controller there is a DC voltage relative to the AC current of the load at 220vac via the output (point C) . When the load current will decrease, because the load will be turned off or disconnected for example, the DC voltage on pin- 7 of the controller will go down. At a certain value of that voltage, the controller (U5) will supply Ov on pin-2 to

R23.This will cause triac U 2 to discontinue so that the coil

CRl of FSl will not be powered and disconnect the 220vac from the output and go back to the initial stat.

Notes:

*1 this feature could be used when using a S. P. S. T relay with a Normally-Open only connection. To eliminate high current via R5 R6 when there is a 220vac on the output.

*2 R20,R21 are used to isolate U5 during programming .
