- the present invention relates in general to portable energy consuming devices and, in its broadest sense, the novel invention utilizes an external power source to store kinetic energy in a portable energy device and simultaneously store electrical energy in an internal power source in the device only during the storing of the kinetic energy such that when the external power source is separated from the device, the internal power source is used to maintain the stored kinetic energy.
- the novel invention relates to improved portable energy consuming devices such as hair management devices and flat clothes iron devices that are brought to a desired operating level, such as temperature, with an external power source and then the external power source is disconnected and an internal power supply, e.g. batteries, maintains only the desired operating level thereby extending the life of the internal power supply as well as the life of the energy consuming device, e.g. heating elements.
- an internal power supply e.g. batteries
- circuits are disclosed for manually controlling a desired set temperature of the energy consuming device, hi commonly assigned co-pending provisional patent applications S.N. 60/545,783; and S.N. 60/573,716; and in commonly assigned U.S. Patent No. 6,732,447, circuits are disclosed for automatically providing input power, Pj n , in an amount equal to the power losses, Pi, (e.g. cooling and system losses) of the portable device so that the power output, P 0 , is equal to the residual power, P r , (e.g. kinetic energy such as heat, mass rotation, and the like).
- the input power supplied is simply equal to the power losses and the residual power is equal to the output power of the device.
- the energy consuming device e.g. hair curling iron, soldering guns, hot glue guns, flat clothes irons, mass rotors, and the like
- a desired operating level e.g. temperature, rotational speed, and the like
- a power source external to the energy consuming device
- dc external direct current
- the external power source is disconnected from the device and an internal power source automatically begins to supply power to the energy consuming device in an amount only sufficient to maintain the desired operating level. In other words, it supplies just enough energy to compensate for power and system losses in the device thereby enabling the residual energy (e.g. temperature, mass rotation, and the like) to be maintained equal to the desired output power.
- the external power source may be ac, dc, RF energy, magnetically coupled energy, and the like.
- the external power source will be identified as simply ac or dc.
- the energy consuming device when a temperature controlled device, may have either a single heating element for accepting an external dc power source output for preheating as well as the internal power source (batteries) output to maintain the desired operating level or an ac heating element for connection to an ac external power source to obtain the desired operating level and a dc heating element for connection to the internal power source to maintain the desired operating level.
- the resistive heating elements may be of several types such as ribbon type resistances arranged in different relationships such as electrically insulated coils wound together in adjacent interposed relationship with each other or in superimposed, electrically insulated, fashion.
- the resistive elements may also be of any known type such as wire wound, ceramic, and the like.
- a switch may be arranged internally of the energy consuming device that disconnects the internal power source from the load (e.g. resistive heating element) when, and only when, the external power source is connected to the energy consuming device.
- the load e.g. resistive heating element
- the connector engages and opens a switch so that the internal power source cannot supply current to the load.
- the switch in the device is closed thereby enabling the internal power source to maintain the desired operating level with the use of signals that control an electronic switch (such as a power FET) that couples the internal power source to the load.
- the energy consuming device is a flat clothes iron, it is mounted on a base that has connectors that engage corresponding mating connectors on the flat clothes iron.
- either a single dc heating element or both a dc heating element and an ac heating element may be used as the heating element in the flat iron, hi either case, the proper power source is coupled to the corresponding connectors on the flat iron to first bring it to the desired operating temperature and then the . flat iron is removed from the base and becomes a portable flat iron. The internal power source then maintains the desired operating temperature using the control signals.
- the flat iron may have no heating element for an external power source but would have the internal power source that can be coupled to an internal heating element.
- the flat iron is mounted on a base unit having a flat heating surface that is powered by an external power source.
- the heat is transferred by conduction, metal to metal, to the flat iron until the flat iron reaches the proper desired operating temperature.
- Connectors on the base unit again engage corresponding connectors on the flat iron to prevent the internal power supply from supplying power to the heating element until the flat iron is removed from the base unit.
- the removed connectors then allow an internal switch to close and connect the internal power supply to the internal heating element to only maintain the desired heat.
- the internal power supply may consist of the batteries without the novel pulsing circuit disclosed herein.
- the unit is heated to the desired temperature with the external power source and then, when the unit is removed from the external power source, the internal power supply, the batteries alone, may be connected to the heating element to maintain the desired heat as long as the batteries last.
- the internal batteries will not last as long as when the novel pulsing circuit is used to pulse battery power to the load but they will last longer than a portable unit that uses the batteries alone to not only bring the unit to the desired temperature but also to maintain the desired temperature.
- the power source must be insulated from the heat generated in the device. This can be accomplished in a number of ways. With a hair curling iron, the power supply (e.g.
- the power source may consist of a plurality of series connected battery cells, a stick type battery, or other type power source (hereafter "power source”) that can simply be inserted in or removed from the handle as necessary.
- the batteries can again be placed in the handle of the flat iron which is already heat insulated from the ironing surface to enable a user to hold the iron by the handle.
- the batteries may consist of a plurality of series connected battery cells or a stick type power source assembly that can simply be inserted in or removed from the handle as necessary.
- the internal power source as stated earlier, may be charged when the energy consuming device is placed on a base unit.
- the present invention relates to a method of creating a portable energy consuming device comprising the steps of forming a body portion with an energy consuming load associated therewith; causing the energy consuming load to achieve a desired operating level using a power source located externally of the body portion; removing externally supplied energy from the energy consuming load when the desired operating level is reached; and only maintaining the desired operating level of the energy consuming load using a power source located internally of the body portion thereby creating a portable energy consuming device.

- FIG. 11 illustrates a control circuit shown in commonly assigned co- pending provisional patent application S.N. 60/573,716 that can advantageously be used with the present invention.
- the device could be brought to the desired operating level or condition with the use of an external power source and then the device was made portable by disconnecting the external power supply, an internal power supply could then be used to just maintain the desired operating level. The device would then be truly portable and could be used without the physical interference of an ac cord.
- the present invention meets these requirements by using an external power source to store kinetic energy (such as temperature or a rotating mass) in a selected energy consuming device until a desired operating level is reached and then the external power source is disconnected from the device to make the device portable. An internal power source is then automatically used to just maintain the kinetic energy at the desired operating level.
- kinetic energy such as temperature or a rotating mass
- FIG. 1 Such a device is disclosed in FIG. 1 wherein is shown a block diagram 10 illustrating a generic embodiment of the present invention.
- an energy consuming device 12 (hereinafter called “device”) has an external power source 14 removably coupled to the device 12 by means of conductors 16 to a load element 18 located within the device to cause the device 12 to reach a desired operating level. Then, when the desired operating level is reached, the external power source 14 is disconnected from the device 12, device 12 becomes portable, and an internal power supply 20 is coupled to its own load element 22 to just maintain the desired operating level of the device 12.
- the internal power source 20 may, as stated earlier, consist of internal batteries only and, in such case, the external power source 14 brings the device to the proper operating temperature and then it is disconnected and the internal batteries, alone, are connected to the device to maintain the temperature of the device.
- the batteries or power source 14 will not last as long as when used with the pulsing circuit disclosed herein but will last longer than a device that uses the internal batteries to both heat the device to a desired temperature and then maintain that desired temperature.
- the internal power source 20 may consist of the internal batteries and a pulsing circuit as will shown hereafter to pulse the power of the internal batteries to the load. In such case, the life of the internal batteries is extended even longer as will be disclosed hereafter.
- a hair curling iron has a metal mass serving as the heated surface and it must be raised to a sufficiently high temperature to enable it to be used. This is accomplished in the prior art by the use of alternating current (ac) and it takes several minutes to bring the metal mass to a temperature sufficient for use in curling hair. Then when it is used, the ac cord must remain attached to keep the iron hot. It is highly desirable to make the curling iron portable and eliminate the physical interference of the ac cord. However, if the curling iron is made portable, no cord is attached and no ac is used. Thus, the internal power source must be placed under a severe power drain to bring the device to the desired operating level (in this example, temperature).
- ac alternating current
- the device 12 is a hair curling iron, it can be heated to the desired operating level or temperature with the external ac power source 14.
- the ac cord 16 is disconnected from the hair curling iron 12 in a well know manner as by means, for example, of unplugging ac connectors from the device 12.
- An internal power source as will be shown hereafter, is then automatically utilized to just maintain the desired operating level or temperature.
- the external ac power source utilizes and is connected to its own ac heating element located within the device 12.
- the internal power source 20 is automatically connected to its own dc heating element 22, as will be explained hereafter, to cause the device 12 to maintain its desired temperature.
- the external power source 14 may be used to charge the internal power source 20 by means of a second conductor 24, shown as a phantom line, whenever the device 12 is mounted in a base unit as will be shown hereafter.
- the device 12 illustrated generally in FIG. 1 could, in addition to a hair curling iron, represent any hair management device, such as a blow dryer, that requires large amounts of energy to get the device to the proper temperature.
- Device 12 in FIG. 1 could also represent a flat clothes iron, a soldering gun, a glue gun, a rotating mass, and the like.
- FIG. 2 is a schematic representation of a device 12 and illustrating a generalized version of the electronics associated therewith.
- the internal power source 20 in FIG. 2 is coupled, through switch 28, to a dc heating element 22.
- a dc heating element 22 When the device 12 is to be brought to a desired operating level, such a temperature, an external ac source 14 and connected power cord 16 has on the end thereof an elongated connector 26 of any well-known type in the art that is inserted in a mating receptacle (not shown) in the device 12 in a well-known manner to connect the external power source to an internally located ac load such as heating element 18, for example only, on lines 32 and 34.
- the ac input can be connected to an ac/dc converter 30, either internal or external (shown here as internal) that can be used to charge the internal batteries 20 in a conventional manner.
- ac heating element 18 causes the device 12, here a temperature device, to reach the desired operating level (temperature in this case)
- the connector 26 is withdrawn from the mating receptacle to make the device portable.
- switch 28 returns to its normally closed position thereby connecting internal power source 20 to its own dc load 22 on line 36.
- a control circuit 38 provides just sufficient energy from the internal power source 20 to cause the device 12 to only maintain the desired operating level.
- the circuit shown schematically in FIG. 3 includes control circuit 38 that is powered by the internal power source 20.
- An electronic switch 40 such as a power FET, is opened and closed by the control circuit 38 with the use of Pulse Time Modulated signals to modulate the power signal to load 22 from the internal power source 20.
- a light emitting diode (LED) 42 may be utilized, if desired, to let the user know that the control circuit 38 is functioning.
- FIG. 4 illustrates a flat clothes iron 46 mounted on a base unit 44 shown in cross-section.
- the flat iron 46 has a handle 47 that is sufficiently temperature insulated from the heated body portion of flat iron 46 to enable a user to pick up and use the heated flat iron 46.
- an external power source 14 is coupled through cord 16 to a connector that is plugged into the base unit in a well-known manner as explained previously.
- external ac power is connected directly to connector 52 by conductor 50 to preheat the iron when a switch on the base (not shown here) is operated by a user when the user desires to use the flat iron.
- the internal power source can be charged by the output from an ac/dc converter 48 on connector 26.
- the iron may be removed from base unit 44 and thus becomes a portable iron.
- the ac/dc converter 48 is shown to be a part of the base unit 44, it can be external to the base unit 44 if desired.
- the flat iron 46 shown in FIG. 4 utilizes first and second heating elements located internally of the flat iron 46.
- One heating element is an ac heating element (to be used by the external power source) and the other is a dc heating element (to be used by the internal power source).
- the flat iron 46 could, if desired, have only one heating element and that is a dc heating element that would be used first during the preheating on the base unit 44 and then, when the flat iron 46 is disconnected from the base unit 44 to make the flat iron portable, the single dc heating element would be connected to the internal power source 20 to just maintain the desired temperature.
- the base unit 44 has an ac/dc converter 48 associated therewith, either internal (as shown) or external to the base unit 44.
- the device uses the dc power source for preheating a single dc heating element and when the device is disconnected from the base unit 44 to make the device portable, the internal dc source is coupled to the same single dc heating element.
- Such a connection would be obvious to one skilled in the art given the assignment of creating such connection and therefore is neither shown nor explained here.
- the resistive heating elements may be wound in a circular fashion about a non-electrically conductive cylinder 17 as shown in FIG. 6A.
- the two resistive elements 18 and 22 are wound about non-electrically conductive cylinder 17 in an interposed, spaced, non-electrical conducting relationship as shown.
- one skilled in the art would know how to create other types of arrangements such as a side-by-side relationship.
- heating elements are of the flat resistive types, one may be superimposed over the other in a non-electrical conducting relationship as shown in FIG. 6B where a flat ac heating element 18 has superimposed thereon and electrically insulated therefrom by insulator 54 a flat dc heating element 22.
- a flat ac heating element 18 has superimposed thereon and electrically insulated therefrom by insulator 54 a flat dc heating element 22.
- FIG. 7 illustrates a base unit 44 on which a hair curling iron 64 (shown in phantom lines) could be mounted for preheating and charging of its internal power supply.
- the internal power supply may be batteries as is well known in the art.
- an ac power source represented by electrical plug 14
- cord 16 is connected by cord 16 to a connector 56 on the base unit 44 as explained earlier.
- the hair curling iron 64 could have a single heating element for both preheating and portable operation. As shown, however, a first heating element is used for preheating with the external ac power source and a second heating element is used for portable operation with the internal dc power source.
- the ac input from the external power source is connected directly to connector 62 on the base unit 44 while the dc power for simultaneously charging the internal power source comes from an ac/dc converter 58 whose dc output is coupled to connector 60.
- the power cord 16 terminates at the base unit 44 with a connector 56.
- connector 56 is identical to the connector 62 on base unit 44. If, for any reason, the portable operation of the device 64 is prohibited, the ac connector 56 can be plugged directly into the device 64 where power is normally supplied by connector 62. In such case, the hair curling iron 64 may advantageously continue to be used as a conventional cord attached, non-portable hair curling device. hi any use of batteries with a heating device, the batteries must not be subject to heating from the heating elements. In a hair curling iron, the batteries may be placed in a heat insulated handle as is well-known in the art and which is heat insulated from the heating element.
- the batteries When the novel invention is used with a flat clothes iron, the batteries must be especially protected from the heat maintained by the large metal mass.
- the batteries may be separate battery cells 20 or a well known battery “stick” 66 that can be inserted in well known fashion into the handle 47. With battery “stick” 66, the battery is simply slid into and out of the handle to replace it or to charge it externally of the flat clothes iron in a well known fashion.
- the top of the handle 47 could be a hinged plate (not shown) that could be opened and closed in a well known manner to remove and insert batteries.
- FIG. 8 One skilled in the art would understand other methods of mounting, and insulating, the batteries to protect them from the heat.
- FIG. 9 is a diagrammatic depiction of a portable flat clothes iron 46 having a handle 47 with batteries 20 (internal power source) located therein.
- the batteries are diagrammatically shown to be connected to a dc load 22 such as a dc heating element while an ac load such as an ac heating element 18 is shown connected to at least one receptacle 50 for receiving power from an external power source while preheating.
- FIG. 10 illustrates schematically an alternate embodiment of the invention.
- the flat clothes iron 46 has no internal heating element for preheating
- the base unit 68 has an upper plate 70 that is preheated by the external power source represented by wall plug 14 through cord 16.
- the flat clothes iron 46 simply sits on the heated plate 70 in metal to metal contact to preheat the flat iron 46.
- the flat iron 46 is preheated, as may be indicated in a well known fashion by LED 76, it is made portable by removing it from the base unit upper plate 70.
- At least one connector 72 has prevented the internal power source 20 from powering the dc heating element during preheating.
- the at least one connector 72 is removed from a corresponding receptacle that enables the portable, internal power, operation as explained previously with respect to FIG. 2.
- FIG. 11 is a schematic diagram of the electronic control circuit for the novel invention herein that supplies only sufficient Pulse Time Modulated energy to the device to replace only load losses and to maintain the desired power output and thereby conserve battery energy that would otherwise be wasted. This diagram has been explained in detail in co-pending commonly assigned provisional patent application S.N. 60/573,716.
- unit 78 is a detector that senses the desired operating level (e.g. a temperature sensor 80 as shown in Fig. 11).
- Oscillator 94 generates, in this case, a sawtooth wave output on line 96 that is coupled, along with the amplified detector 78 signal on line 90 to a comparator 92.
- a comparator 92 As long as the amplitude of the amplified output of detector 78 on line 90 is greater than the amplitude of the oscillator 94 output on line 96, there is a constant output from the comparator 92 through resistor 100.
- This signal is coupled through switch 28 to the gate of power FET 102 causing it to conduct and apply maximum power to the load 22.
- the device has, in this instance, an ac heating element 18 that is heated to bring the device to the desired operating temperature.
- the device is first heated to the desired operating temperature with an external ac power supply 44.
- the external power supply 44 is coupled to the energy consuming device by means of, in this case, a male connector 26 that makes contact with points 75 and 76 (on line 16) to provide power to the ac load 18 in the device.
- Switch 74 is a double pole, single throw switch that first couples the external ac source to the ac load heating element 18.
- the other half of switch 74 couples the internal power supply (batteries) to the control circuit described above.
- the control circuit uses such little power, little drain is placed on the internal batteries during the time the external power supply is bringing the device to the desired operating temperature.
- the male connector represented by phantom line 26, physically opens switch 28 thus preventing the FET from receiving any signal from the control circuit of the device.
- no power is being supplied to the dc load 22 during the time that the external ac power source is heating the device to the desired operating temperature with the use of ac heating element 18.
- the ac heating element or load 18 causes the device to reach the desired temperature (which can be indicated in a well known manner by illumination of an LED)
- the device is removed from its base and the male connector 26 is removed from the device closing switch 28 and allowing the signal from the comparator 92 of the control circuit to be connected to the power FET 102 which begins to apply power to the dc load 22.
- the dc load 22 is in physical proximity to the metal mass that has been heated by the external power source 44, the dc load 22 is already heated to the approximate desired operating temperature and the power FET 102 now is Pulse Time Modulated by the control circuit to provide just enough energy to dc load 22 to maintain the desired operating temperature of the device.
- An LED 103 maybe coupled across FET 102 and pulses with the pulsing of the FET to indicate to the user that the control circuit is functioning.
- a novel improved portable energy consuming device that uses an external power source to cause the device to reach a desired operating level and then when the device is removed from its base, the external power source is disconnected from the device and the internal power supply is then automatically connected to a dc load to maintain the desired operating level of the device.
- a control circuit is coupled between the internal power source and the dc load to Pulse Time Modulate the signal applied thereto to replace only load losses and to just maintain the desired operating level.
- the desired operating level is intended to mean a desired operating temperature, a desired operating rpm, or any other type of load operating condition that has kinetic energy that will maintain the desired operating condition if sufficient energy is provided to just replace the device losses.
- electrostatic switch as used herein is intended to cover suitable switch that can be controlled to intermittently supply power to a load including mechanically operated switches such as a relay or a solid state switch such as a Field Effect Transistor (FET) as discussed herein previously.
- mechanically operated switches such as a relay or a solid state switch such as a Field Effect Transistor (FET) as discussed herein previously.
