Abstract

An improved portable energy consuming device that uses an external power source to store kinetic energy in the device until a desired level is reached and then the external power source is disconnected from the device to form a portable device and an internal power source is automatically used to maintain the desired kinetic energy level. Thus, the external power source causes at least one device load to reach a desired operating level such as temperature and then, when the device is removed from a base on which it is mounted, the external power source is disconnected and an internal power source is automatically connected to the at least one device load to cause it to just maintain the desired operating level. A control circuit is coupled between the internal power source and its associated internal load to cause only sufficient power to be supplied to the load to maintain the desired operating level.

Description

PORTABLE ENERGY CONSUMPTION DEVICE BACKGROUND OF THE INVENTION 1. Field of the invention The present invention relates in general to portable energy consuming devices and, in its broadest sense, the invention uses an external energy source to store kinetic energy in a portable energy device and simultaneously store electrical energy in an internal energy source in the device only during storage of the kinetic energy in such a way that when the external energy source is separated from the device, the internal energy source is used to maintain the stored kinetic energy. In particular, the novel invention relates to improved portable power consumption devices such as hair management devices and flat clothing ironing devices that are brought to a desired level of performance, such as temperature, with a external power source and then the external power source is disconnected and an internal power source, eg batteries, maintains only the desired level of operation, thus prolonging the duration of the internal power supply as well as the duration of the power supply device. energy consumption, for example heating elements. 2. Description of prior Art There are numerous portable power consumption devices. There are devices for hair management such as hair curlers or dryers that use batteries to supply the necessary heat.

These devices produce a significant current drain on the batteries and shorten the life of the batteries. In U.S. Patent Nos. 6,449,870 and 6,718,651 of the same assignee, circuits are disclosed for manually controlling a desired adjusted temperature of the energy consuming devices. In the provisional US patents applications of the same transferee Act No. 60 / 545,783 and Act No. 60 / 573,716 and in the US patent of the same assignee No. 6.1732.447, circuits are disclosed to automatically provide input power, Pin , in an amount equal to the energy losses, Pi, (for example cooling and system losses) of the portable device such that at the energy output, P0, is equal to the residual energy, Pr (for example, kinetic energy) such as heat, mass rotation, and the like).

Therefore, at a desired operating level, such as a desired temperature, the input power delivered is simply equal to the energy losses and the residual energy is equal to the output energy of the device.

While these devices work well, there is a huge drain of current on the batteries to make the portable device get a desired level of performance. For example, when a mass needs to be heated to a particular temperature, it takes a large amount of current from the battery to heat the mass (such as the metal mass a curling iron of the hair) to the desired temperature. By controlling the drainage of current on the batteries as revealed in the provisional patent pending applications, the remaining useful life of the batteries can actually be extended.

However, it would be desirable to use an external power source to cause the mass to reach the desired temperature and then disconnect the external power source and enable the internal power source, i.e. the batteries, to maintain only the desired temperature of the battery. novel portable power consumption device. In this novel system, the useful life of the batteries is prolonged much more because very little drainage of the batteries is used UNTIL the desired level of operation has already been reached and then the device is used as a portable device with the power source internal maintaining the desired level of performance (for example, temperature). If the internal power source fails for some reason, the power consumption device can be connected directly to the external power source and used in conventional manner.

EXTRACT OF THE INVENTION With the present invention, the energy consuming device (for example, a hair curling iron, welding guns, hot glue guns, flat clothes irons, dough rotors and the like) is brought to the desired performance level ( for example, temperature, rotational speed, and the like) with a power source external to the power consumption device such as an alternating current source (ac) or a direct current source (ce). Once the device reaches the desired level of operation, the external power source is disconnected from the device and an internal power source automatically begins to supply power to the power consumption device in an amount only sufficient to maintain the level of operation desired, in other words, supplies only enough energy to compensate for energy and system losses in the device thus allowing the residual energy (e.g., temperature, mass rotation, and the like) to remain the same as the desired output energy .

The external energy source can be ca, ce, RF energy, magnetically connected energy, and the like. Henceforth, for simplicity, the external energy source will be identified simply as ca or ce. The energy consumption device, when it is a temperature-controlled device, can have a single heating element to accept an output from the external power source to preheat such as the output of the internal power source (batteries) to maintain the desired level of operation or an AC heating element for connection to an external ac power source to obtain the desired energy level and a CE heating element for connection to the internal power source to maintain the level of desired operation.

When both an AC heating element and a CE heating element are used, the resistive heating elements can be of various types such as ribbon type resistors arranged in different ratios such as electrically insulated coils wound together in interleaved relation adjacent one to the other. another or electrically isolated, ~ superimposed. The resistive elements may also be of any known type such as wound cable, ceramic, and the like.

A switch can be disposed internally in the power consumption device that disconnects the internal energy source from the load (for example, - a resistive heating element) when, and only when, the external power source is connected to the consumer device of energy. Therefore, when a connector (plug) connects the power consumption device to the external power source, the connector is connected and opens a switch so that the internal power source can not supply current to the load.

However, when the device reaches the desired operating level and the external power source is disconnected from the device by removing the connector from the junction with the device, the switch of the device is closed allowing the internal power source to maintain the level of desired operation using signals that control an electronic switch (such as an energy FET) that connects the internal power source to the load.

When the energy consuming device is a flat iron for garments, it is mounted on a base having connectors that are attached to the corresponding connectors on the flat iron for garments.

Again, you can use a heating element of either a heating element of the ce or an ac heating element as well as the heating element in the flat plate. In any case, the correct power source is connected to the corresponding connectors on the flat iron to bring it first to the desired operating temperature and then the flat iron is removed from the base and turned into a portable flat iron. The internal power source then maintains the desired operating temperature using the control signals.

If desired, the flat iron may not have any heating element for an external power source but would have the internal power source that can be connected to an internal heating element.

In that case, the flat plate is mounted on a base unit having a flat heating surface which is fed with an external power source. The heat is transferred by conduction, from metal to metal, until the flat iron reaches the desired operating temperature. The connectors that are on the base unit are again attached to the corresponding connectors on the flat plate to prevent the internal power source from supplying power to the heating element until the flat plate is removed from the base unit. The removed connectors then allow an internal switch to close and connect the internal power source to the internal heating element only to maintain the desired heat.

In that case, it is clear that the internal power source can comprise the batteries without the novel driving circuit disclosed herein. Therefore, 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 batteries alone, can be connected to the heating element for keep the desired heat all the time the batteries last. Internal batteries do not last as long as when the novel drive circuit is used to boost battery power to the load but they last longer than a portable unit that uses the batteries alone not only to bring the unit to the desired temperature but also to maintain the desired temperature. It must be understood that with the internal energy source, the energy source must be isolated from the heat generated in the device. This can be done in many ways. With a hair curling iron, the power supply (for example, the batteries) can be placed on the handle of the hair that is at the opposite end of the curling iron from the heating element. The power source may comprise a plurality of battery elements connected in series, a straight-type battery, or a power source of another type (hereinafter the "power source") that can simply be inserted or removed from the handle according to be necessary.

With a flat iron for clothing, the batteries can again be placed on the handle of the flat iron that is insulated by heat from. the ironing surface to allow the user to hold the iron with the handle. Again, the batteries may comprise a plurality of battery elements connected in series or a straight-type power source assembly which can simply be inserted or removed from the handle as required. The internal power source, as stated above, can be charged when the energy-consuming device is placed on the base unit.

Therefore, an object of the present invention is to provide a portable power consumption device that uses an external power source to allow a desired level of operation and an internal power source to be reached only to maintain the desired level of performance once the device is disconnected from the external power source to make it portable.

Another object of the present invention is to provide a single charge of ce in the portable power consumption device both to bring the device to the desired level of operation with an external power source and to maintain the desired level of operation with the source of internal power when the device is disconnected. from the external power source and it becomes portable.

Another object of the present invention is to provide a first ac load to bring the energy consuming device to a desired operating level with an external power source and a second charge of ce to maintain the desired level of operation with a source of energy. Internal power when the device is disconnected from the external power source and made portable.

Still another objective of the present invention is to provide a base unit on which the energy consumption device can be placed; the base unit has an external power source to allow the power consumption device to be brought to the desired operating level and, optionally, to charge the internal power source of the power consumption device only for as long as the power source external is feeding the device of energy consumption.

Still another object of the present invention is to connect a control circuit between the internal power source and the energy-consuming load to automatically maintain the desired level of operation thus conserving the internally located power source as well as prolonging the useful life of the load that consumes energy.

Therefore, the present invention relates to a method of creating a portable power consumption device comprising the steps of forming a body portion with a charge that consumes energy associated with it; causing the energy-consuming charge to reach a desired level of operation using a power source located externally to the body portion; withdraw the externally supplied energy from the energy-consuming load when the desired level of operation is reached; and only maintaining the desired level of performance of the energy-consuming charge using the energy source located internally to the body portion thus creating a portable power consumption device.

The figure. 11 illustrates a control circuit shown in the provisional pending patent application of the same assignee Act No. 60 / 573,716 that can be used advantageously with the present invention.

DETAILED DESCRIPTION OF THE INVENTION It is well known that devices that require significant energy to allow them to reach a desired level or operating conditions are difficult to manufacture in portable devices due to the size of the batteries or the internal power source that is required only to do the device reaches the desired level of operation. By the time the desired level of operation is reached, the internal energy source (eg, batteries) the energy is so depleted that little energy remains from the internal energy source to use it only to maintain the desired level of performance.

If the device could be brought to the desired operating level or conditions using an external power source and then the device was made portable by disconnecting the external power source, an internal power source could then be used only to maintain the desired level of performance .

The devices would then be truly portable and could be used without the physical interference of an AC cable.

The present invention meets these requirements by using an external energy source to store kinetic energy (such as temperature or mass of rotation) in a selected energy consumption device until a desired heating level is reached and then the external energy source it is disconnected from the device to make the portable device, an internal power source is then automatically used only to maintain the kinetic energy at the desired level of operation.

That device is disclosed in Figure 1 where a block diagram -10 illustrating a generic embodiment of the present invention is shown. As can be seen, a power consumption device 12 (hereinafter referred to as "device") has a power source 14 removably connected to the device 12 by means of the cables 16 to a charging element 18 located inside the device for to make the device 12 reach the desired level of operation. Then, when the desired level of operation is reached, the external power source 14 is disconnected from the device 12, the device 12 becomes portable, and an internal power source 20 is connected to its own charging element 22 only to maintain the level of desired operation of the device 12.

The internal energy source 20 can, as is. said previously, to understand only internal batteries and, in that case, the external power source 14 brings the device to the correct operating temperature and then disconnects and the internal batteries, alone, are connected to the device to maintain the temperature of the device. The batteries or power source 14 do not last long when used with the driving circuit disclosed herein but last longer than a device that uses the internal batteries both to heat the device to the desired temperature and to then maintain that desired temperature .

Of course, the internal power source 20 may comprise the internal batteries and a driving circuit shown below to drive the energy of the internal batteries to the load. In that case, the duration of the internal batteries is further extended as will be disclosed later herein.

Let us think, only by way of example, of a hair curling iron. The plate has a metal mass that serves as the heated surface and must be raised to a temperature * high enough to be used. This is achieved in the prior art by using alternating current (ac) and it takes several minutes to bring the metal mass to a temperature sufficient to use the curling iron. Then, when used, the AC cord should be kept connected to keep the iron warm.

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 cables are connected and no alternating current is used. Therefore, the internal power source must be placed under a severe drain of energy to bring the device to the desired operating level (in this example, the temperature).

Therefore, it can be observed with the block diagram of Figure 1 that if the device 12 is a curling iron of the hair, it can be heated to the level or to the desired operating temperature with the external ac power source 14. When the mass of the curling iron reaches the level, or the desired operating temperature, the ac wire 16 is disconnected from the crimper plate 12 in a known manner such as by unplugging the ac connectors of the device 12. A source of internal power, as will be shown later, then automatically used only to maintain the desired level or operating temperature.

In the generalized embodiment shown in Figure 1, the external AC power source uses and connects to its own AC heating element located inside the device 12.

Once the AC cord is disconnected from the device 12, the source of internal energy 20 is automatically connected to its own heating element 22, as will be explained hereinafter, to cause the device 12 to maintain its desired temperature.

In addition, as shown in Figure 1, the external power source 14 can be used to charge the internal power source 20 with a second cable 24, which is shown as an imaginary line, provided that the device 12 is mounted in a unit of base- as will be shown later.

Naturally, the device 12 illustrated generally in Figure 1 can, in addition to a curling iron of the hair, represent any device for hair management, such as a dryer, which requires large amounts of energy for the device to reach the correct temperature . The device 12 of Figure 1 can also represent a flat iron for garments, a welding gun, a glue gun, a rotating mass and the like.

Furthermore, when a dryer represents the hair management device, the duration of the batteries can be extended further by causing the air generated by the fan to pass over the batteries and cool them. It is well known that as batteries are used continuously for a prolonged period of time, the internal resistance of the batteries increases. This increased resistance causes the batteries to heat up and also decreases their external output voltage. If the batteries are then cooled, the output voltage returns to a higher level. Therefore, this unique method of using the ventilator to cool the batteries prolongs the life of the batteries during a given OPERATION cycle and also prolongs the entire battery life. That improvement is a valuable asset for the use of portable devices.

Figure 2 is a schematic representation of a device 12 and illustrates a generalized version of the electronic elements associated therewith. The internal power source 20 of Figure 2 is connected, via the switch 28, to a heater element 22. When the device 12 is to be brought to a desired operating level, such as a temperature, an ac source external 14 and a connected power cable 16 has on the end an elongated connector 26 of any type known in the art that is inserted into a coupled receptacle (not shown) in the device 12 in a known manner to connect the power source external to an internally located ac load such as the heating element 18, by way of example only, on lines 32 and 34.

At the same time, if desired, the ac input can be connected to an ac / dc converter 30, internal or external (here shown as internal) that can be used to charge the internal batteries 20 in a conventional manner.

When the ac heating element 18 causes the device 12, hereby a temperature device, to reach the desired operating level (temperature in this case), the connector 26 is removed from the coupling receptacle to make the portable device. When this occurs, the switch 28 returns to its normally closed position thereby connecting the internal energy source 20 to its own charge from ce 22 to line 36. As will be shown below in relation to Figure 3 and Figure 11, a control circuit 38 provides only sufficient energy from the internal power source 20 to cause the device 12 to maintain only the desired level of operation.

The circuit shown schematically in Figure 3 includes the control circuit 38 which is supplied with the internal power source 20. When the connector 26 (here represented by an imaginary line) is disconnected from the device 12, the switch 28 It closes as explained above.

An electrical switch 40, such as an energy FET, is opened and closed with the control circuit 38 using Pulse Time Modulated signals to modulate the energy signal to the load 22 from the internal power source 20. It can be using a light-emitting diode (LED) 42, if desired, to allow the user to know that the control circuit 38 is functioning.

The novel invention works well with any load that requires heavy current to bring it to a desired level of operation as explained above. Figure 4 illustrates a flat garment mat 46 mounted on a base unit 44 shown in cross section. The flat plate 46 has a handle 47 that is sufficiently insulated from the temperature of the heated body portion of the plate 46 to allow a user to lift and use the heated flat plate 46.

It will be noted in Figure 4 that an external power source 14 is connected through the cable 16 to a connector that is plugged into the base unit in a manner known as previously explained. In this example, the external ac source is directly connected to the connector 52 by a cable 50 for preheating the iron when a user operates a switch on the base (not shown here) when he wants to use the flat iron. At the same time, if desired, the internal power source can be charged with the output from a AC / DC converter 48 on the connector 26. When the iron reaches the desired temperature as can be shown in a known manner with the LED 76 shown in Figure 10, the plate can be removed from the base unit 44 and therefore a portable plate is made. It should be noted that while the ac / dc converter 48 is shown to be part of the base unit 44, it may be external to the base unit 44 if desired. Therefore, the flat plate 46 shown in Figure 4 uses first and second heating elements located inside the flat plate 46. A heating element is an ac heating element (to be used with the external power source). ) and the other is a CE heating element (to be used with the internal power source).

The flat plate 46 can, if desired, have only one heating element and that is a heating element that would be used first during preheating on the base unit 44 and then, when the flat plate 46 is disconnected from the base plate 44. the base unit 44 for making the portable flat iron, the single CE heating element would be connected to the internal power source 20 only to maintain the desired temperature. As shown in Figure 5, the base unit 44 has a AC / DC converter 48 connected to it, inside (as shown) or outside of the base unit 44. The device, then, uses the power source of CE to preheat a single CE heating element and when the device is disconnected from the base unit 44 to make the portable device, the internal power source is connected to the same single CE heating element. That connection would be obvious to an art expert who is assigned to create that connection and therefore is not shown or explained in the present.

When it is desired to use two heating elements, an ac and a ce element, these can be formed in any desired manner. For example, if the device is a hair curling iron, the resistive heating elements can be wound in a circular fashion around a non-electrically conductive cylinder 17 as shown in Figure 6A. The two resistive elements 17 and 22 are wound around the non-electrically conductive cylinder 17 in an electrically non-conductive, separate, interleaved relationship as shown. Naturally, an expert in the art would know how to create other types of arrangements such as a relationship with one another.

If the heating elements are of the flat resistive type, one can be superimposed on the other in a non-electrically conductive relationship as shown in Figure 6B where an ac heating element 18 has a plane heater element superimposed thereon and insulated electrically from it by an insulator 54. A person skilled in the art would know the other ways in which the two heating elements 18 and 22 can be advantageously arranged.

Figure 7 illustrates a base unit 44 on which a hair curling iron 64 (shown in imaginary lines) can be mounted to preheat and charge its internal energy source. The internal energy source can be batteries as is well known in the art. Again, an ac power source, represented by the electrical outlet 14, is connected by the cable 16 to a connector 56 on the base unit 44 as explained above. As also explained above, the hair curling iron 64 may have a single heating element for preheating and portable operation. As shown, however, a first heating element is used to preheat with the external AC power source and a second heating element is used for portable operation with the internal power source.

The ac input from the external power source is connected directly to the connector 62 on the base unit 44 while the power of ce to simultaneously charge the internal power source comes from a ac / dc converter 58 whose output of CE is connected to connector 60.

The power cable 16 terminates in the base unit 44 with a connector 56. Advantageously, the connector 56 is identical to the connector 62 that is on the base unit 44. If, for any reason, portable operation of the device 64 is prohibited. , the AC connector 56 can be plugged directly into the device 64 where the energy is normally supplied by the connector 62. In that case, the hair curling iron 64 can advantageously continue to be used as a non-portable hair curling iron, connected by a conventional cable.

In any case of batteries with a heating device, the batteries should not be subject to heating from the heating elements. In a hair curling iron, the batteries can be placed on a handle isolated from the heat as is well known in the art and which is isolated from the heat of the heating element.

When the novel invention is used with a flat iron for garments, the batteries must be specially protected from the heat maintained by the large mass of metal. One such way of isolating the batteries from heat is shown in Figure 8. As shown, the batteries can be separate battery elements 20 or a known "straight" battery 66 that can be inserted in known manner in the handle 47. With the "straight" battery 66, the battery simply slides in and out of the handle to replace it or charge it externally to the flat iron for clothing in known manner. Similarly, the upper part of the handle 47 can be a plate with a hinge (not shown) that can be opened and closed in a known manner to remove and insert batteries. An expert in the art would understand other methods of mounting and isolating the batteries to protect them from heat.

Figure 9 is a graphic representation of a portable garment flat iron 46 having a handle 47 with batteries 26 (internal energy source) located therein. The batteries are shown in a diagram connected to a load of ce 22 such as a CE heating element while an AC load such as an AC heating element 18 is shown connected to at least one receptacle 50 for receiving energy from a External power source while preheating.

Figure 10 illustrates schematically an alternative embodiment of the invention. | In this embodiment, the flat garment plate 46 has no internal heating element to preheat. In this embodiment, the base unit 68 has an upper plate 70 which is pre-heated with the external power source represented by the wall socket 14 through the cable 16. The flat garment plate 46 simply rests on the plate heated 70 in metal-to-metal contact to preheat the flat plate 46. When the flat plate 46 is preheated, as may be indicated in a manner known by the LED 76, it is made portable by removing it from the top plate 70 of the unit. base. At least one connector 72 has prevented the internal power source 20 from feeding the CE heating element during preheating. When the flat plate 46 is removed from the base unit 68, at least one connector 72 is removed from the corresponding receptacle allowing the internal, portable power operation, as previously explained with respect to Figure 2.

Of course, in all of the embodiments described above, a switch 74 illustrated in a diagram in Figure 10 can be used to prevent the device 12 from being preheated while being placed on the base unit.

Figure 11 is a schematic diagram of the electronic control circuit for the novel invention of the present which supplies only sufficient pulse-modulated energy to the device to replace only the losses and to maintain the desired energy output and thus preserve the energy of the device. the batteries that would otherwise be spent. This diagram has been explained in detail in the provisional patent application in process of the same transferee Act No. 60 / 573,716.

In summary, however, the unit 76 is a detector that captures the desired level of operation (e.g., a temperature sensor 80 shown in Figure 11). The oscillator 94 generates, in this case, a serrated wave output on the line 96 which is connected, together with the amplified signal of the detector 78 on the line 90 to a comparator 92. Provided that the amplitude of the amplified output of the detector 78 in line 90 is greater than the amplitude of the output of oscillator 94 in line 96, there is a constant output from comparator 92 through resistor 100. This signal is connected through switch 28 to the door of the power FET 102 which causes it to drive and apply the maximum energy to the load 22.

However, as explained above, to save the internal batteries, the device has, in this case, a ca. 18 heating element that is heated to bring the device to the desired operating temperature. As can be seen in Figure 11, the device is first heated to the desired operating temperature with an external AC power source 44. The external power source 44 is connected to the power consumption device, in this case, by means of a male connector 26 that contacts the tips 75 and 76 (on line 16) to provide power to the ac load 18 in the device. The switch 74 is a two-pole one-way switch that first connects the external AC source to the ac load heating element 18. In addition, the other half of the switch 74 connects the internal power supply (batteries) to the power circuit. control described above. Since the control circuit uses so little energy, little drainage is placed on the internal batteries for as long as the external power source is bringing the device to the desired operating temperature. As explained above, the male connector, represented by the imaginary line 26, physically opens the switch 28 thus preventing the FET from receiving any signal from the control circuit of the device. Therefore, no energy is applied to the head load 22 during the time that the external AC power source is heating the device to the desired operating temperature using the AC heating element 18. When the AC heater element is or the load 18 causes the device to reach the desired temperature (which can be indicated in a known manner by lighting an LED), the device is removed from its base and the male connector 26 is removed from the switch that closes the device 28 and allows the signal of the comparator 92 of the control circuit is connected to the energy FET-102 which starts to apply energy to the load of ce 22. As the load of ce 22 is physically close to the mass of metal that has been heated with the energy source external 44, the load of ce 22 is already heated to the approximate desired operating temperature and the energy FET 102 is now modulated by pulse time by the control circuit to provide sunshine ample energy to the load of ce 22 to maintain the desired operating temperature of the device.

If desired, an LED 103 can be connected through the FET 102 and drive the FET to indicate to the user that the control circuit is functioning.

Therefore, a novel improved portable power consumption device that uses an external power source to make the device reach a desired level of operation has been developed and then when the device is removed from its base, the external power source It disconnects from the device and the internal power supply then automatically connects to the CE load to maintain the desired operating level of the device.
