No. 60/374,601, filed Apr. 22, 2002; and U.S. Provisional Application Ser. No. 60/426,438, filed Nov. 14, 2002.
The present invention relates to methods and compositions useful for delivering volatile materials to a fabric article.
Volatile materials, such as certain perfume materials, are required to produce certain highly desired scents or provide certain fabric benefits. Unfortunately the benefit of such volatile materials is not obtained when applied during the operation of application devices such as clothing dryers, as such materials and compositions are unevenly deposited, and/or vaporized and expelled from the dryer before the end of the drying cycle.
The present invention relates to a method of delivering a material, during the operation of an application device, to a fabric article contained in said device, said method comprising the step of applying said material to said fabric article during the operation of said application device.
As used herein, “treatment material” means a material or combination of materials that can deliver one or more of the following benefits to a fabric article; softening, crispness, water and/or stain repellency, refreshing, antistatic, anti-shrinkage, anti-microbial, durable press, wrinkle resistance, odor resistance, abrasion resistance, anti-felting, anti-pilling, appearance enhancement, and mixtures thereof.
As used herein, “fabric treatment composition” means a composition that comprises one or more treatment materials, or one or more perfume materials, or combinations thereof. Suitable forms of treatment compositions include, but are not limited to, fluidic substances, such as liquids or gases, and solid compounds, such particles or powders.
As used herein, the terms “treatment composition”, “fabric treatment composition” and “benefit composition” are synonymous.
As used herein, “perfume” means a mixture of perfume materials.
As used herein, the articles “a” and “an”, when used in a claim, are understood to mean one or more of the material that is claimed or described.
For the purposes of the surfactants described herein, it should be understood that the terms “alkyl” or “alkenyl” include mixtures of radicals that can contain one or more intermediate linkages such as ether or polyether linkages or non-functional substituents such as hydroxyl or halogen radicals wherein the radical remains of hydrophobic character.
Applicants' delivery method comprises the steps of monitoring an operating temperature of a drying apparatus during a drying cycle of said drying apparatus and applying a fabric treatment composition to a fabric article during said drying cycle of said drying apparatus, said application occurring after said drying apparatus has reached a first control operating temperature. For example, said first control operating temperature may be a predetermined temperature that is entered by a user, or is set by a computing device in the system controller. In that instance, the predetermined temperature (as the first control operating temperature) could be set equal to or higher than 60° C., or even equal to or higher than 70° C.
Alternatively, the first control operating temperature may be a maximum operating temperature, in which the system controller repetitively or continuously samples or measures the actual operating temperature until it determines that a maximum operating temperature has been achieved; typically, this determination would be made by observing that the actual temperature has begun falling during operation of the drying apparatus. Said maximum operating temperature (as a physical temperature in degrees C. or F.) need not be specified or predetermined by the system controller, but can be virtually any suitable temperature that the drying apparatus is capable of producing in its normal operation. As such, the maximum operating temperature may typically fall within a range such that it is equal to or higher than 60° C, or perhaps equal to or higher than 70° C.
In another aspect of Applicants' invention, said invention comprises the steps of monitoring an operating temperature of a drying apparatus during a drying cycle of said drying apparatus; and applying a fabric treatment composition to a fabric article after said drying apparatus has reached a first maximum operating temperature (e.g., as a control operating temperature) and then returned to a second, lower operating temperature. Said first maximum operating temperature may be about 60° C. or higher and said second operating temperature may be less than about 60° C. Alternatively, said first maximum operating temperature may be about 70° C. or higher and said second operating temperature may be less than about 70° C.
In another aspect of Applicants' invention, said invention comprises the steps of monitoring an operating temperature of a drying apparatus during a drying cycle of said drying apparatus; and applying a fabric treatment composition to a fabric article after said drying apparatus has reached a first maximum operating temperature (e.g., as a control operating temperature) and then returned to a second operating temperature, but before a third operating temperature is reached. Said first maximum operating temperature may be about 70° C. or higher, said second operating temperature may be less than about 70° C. and said third operating temperature may be greater than about 20° C. Alternatively, said first maximum operating temperature may be 60° C. or higher, said second operating temperature may be less than about 60° C., and said third operating temperature may be greater than about 25° C. Alternatively, said first maximum operating temperature may be 60° C. or higher, said second operating temperature may be less than about 50° C., and said third operating temperature may be greater than about 30° C.
In one aspect of Applicants invention the treatment composition that is applied, in accordance with one of the aforementioned temperature or time profiles and by a processes including, but not limited to, spraying, to the fabric article comprises one or more perfume materials having a boiling point of less than or equal to 250° C. at 1 atmosphere. Suitable perfume materials and sources for obtaining such materials are described in the present specification under the heading “Fabric Treatment Composition”.
In one aspect of Applicants' invention the treatment composition that is applied, in accordance with one of the aforementioned temperature or time profiles and by a processes including, but not limited to, spraying, to the fabric article comprises, a perfume that comprises at least about 30% by weight of a perfume material with a boiling point of less than or equal to 250° C. at 1 atmosphere.
In one aspect of Applicants' invention the treatment composition that is applied, in accordance with one of the aforementioned temperature or time profiles and by processes including, but not limited to, spraying, to the fabric article is a treatment composition that can comprise at least 0.005 wt. %, 0.005 wt. % to 10 wt. %, or 0.01 wt. % to 2 wt. %, 0.1 wt.% to 0.95 wt.%, of a material such as a perfume, said perfume comprising at least 30 wt. %, 30 wt. % to 90 wt. %, or 30 wt. % to 70 wt. %, or 30 wt. % to 50 wt. % of a perfume material having a boiling point of less than or equal to 250° C. at 1 atmosphere; optionally an additional fabric treatment material; an optional carrier, an optional moiety that is capable of acquiring an electric charge and optionally, capable of retaining an electric charge for a time period sufficient for the electrically charged liquid to contact a fabric article being treated, and the balance of one or more adjunct ingredients.
In one aspect of Applicants' invention the material that is applied, in accordance with one of the aforementioned temperature or time profiles and by processes including, but not limited to, spraying, to the article comprising a fabric, comprises a material that has a flash point, as measured according to American Society for Testing and Materials (ASTM) method D93-02a, of about 30° C. or higher, about 60° C. or higher, about 90° C. or higher, about 30° C. to about 400° C., about 60° C. to about 300° C., or about 90° C. to about 232° C.
FIGS. 1-4 illustrate one embodiment of an exemplary fabric article treating system for use in the present invention, while FIGS. 5-7 depict a suitable controller, and other electrical and electronic devices for use in the present invention. The methodologies for executing the above profiles are described in greater detail below, in the form of flow charts on FIGS. 11-12. Referring now to the embodiment of FIG. 1, a “stand-alone” controller and dispenser unit (i.e., as a self-contained device), generally designated by the reference numeral 10, is illustrated as having two major enclosures (or housings) 20 and 50. In this embodiment, the enclosure 20 acts as an “inner housing” which is located in the interior of a fabric article drying appliance (e.g., a clothes dryer), while the enclosure 50 acts as an “outer housing” that is located in the exterior of the fabric article drying appliance. The enclosure 50 may be mounted on the exterior surface of the fabric article drying appliance door, however, it may instead be mounted on any exterior surface, non-limiting examples of which include: the side walls, the top walls, the outer surface of a top-opening lid, and the like, including a wall or other household structure that is separate from the fabric article drying appliance. Furthermore, the enclosure 20 may be mounted on any interior surface of the fabric article drying appliance, examples of which include, but are not limited to: the interior surface of the door, the drum of the fabric article drying appliance, the back wall, the inner surface of a top-opening lid, and the like.
In FIG. 1, a discharge nozzle 24 and a “door sensor” 22 are visible on the inner housing 20, which also includes a benefit composition-holding reservoir 26 within an interior volume of the inner housing 20. The reservoir 26 may be used to hold a benefit composition. The discharge nozzle 24 can act as a fluid atomizing nozzle, using either a pressurized spray or, along with an optional high voltage power supply (not shown in FIG. 1) it can act as an electrostatic nozzle. One suitable example of a fluid atomizing nozzle is a pressure swirl atomizing nozzle made by Seaquist Dispensing of Cary, Ill. under the Model No. of DU-3813. The benefit composition can comprise a fluidic substance, such as a liquid or a gaseous compound, or it can comprise a solid compound in the form of particles, such as a powder, or solid particles in solution with a liquid. Reservoir 26 can be of essentially any size and shape, and could take the form, for example, of a pouch or a cartridge; or perhaps the reservoir could merely be a household water line for situations in which the benefit composition comprises potable water.
The inner housing 20 and outer housing 50 are typically in electrical communication. In the embodiment of FIG. 1, a flat cable 40 (also sometimes referred to as a “ribbon cable”) is run between the two housings 20 and 50, and travels along the inner surface of the fabric article drying appliance door 15 (see FIG. 8, for example), over the top of the door 15, and down the exterior surface of the door 15.
The fabric article treating apparatus 10 can be enhanced by use of certain sensors, examples of which include but are not limited to a door (or lid) sensor 22, a motion sensor 36, a humidity sensor 46, and/or a temperature sensor 48. An analog output temperature sensor can be used to provide an analog signal along the electrical conductor 86 that leads back to the controller in the outer housing 50. (It should be noted that some temperature sensors have a serial bus to carry a digital output signal, rather than outputting an analog voltage.) The temperature sensor 48 may not be necessary for many of the control features of the treating apparatus 10, however, the interior temperature of the drying appliance could be used to determine the proper environmental conditions for certain spraying events to occur, particularly if a spraying event of the benefit composition in reservoir 26 is to take place during a “cool down” cycle of the drying appliance. This configuration will be discussed in greater detail below. In addition, the temperature sensor 48 can also be used as an indicator that the drying appliance is operating properly—if the drying appliance has not warmed up to a predetermined minimum temperature, then its heating element (or burner) may not be working correctly, and it may or may not be better if the benefit composition was not being sprayed in that circumstance.
The major components of the exterior housing 50 typically comprise the electronics 54 and the power source 52. For example, if power source 52 comprises four D-cell batteries connected in series, a +6 volt DC voltage will be provided to a set of DC power supplies generally designated by the reference numeral 58. The schematic drawings provided in FIGS. 6A-6C and 7 will show these power supplies 58 in greater detail, but for discussion purposes only, it will be presumed that more than one DC power supply voltage will be required by the control circuit in the outer housing 50. One of the DC power supply voltages provides energy for the high voltage power supply 28, via the electrical conductor 70 that runs through the flat cable 40. Another output voltage is provided to a microcontroller 60, which in the exemplary embodiment depicted in FIGS. 6A-6 C, requires a +3.3 volt DC power supply. In the exemplary embodiment of FIGS. 6A-6C, a digital-to-analog converter (DAC) 62 is used, and the device provided by Analog Devices of Norwood, Mass. (Part No. AD 5301), requires a +5 volt DC power supply. All of these power supplies are provided by the “set” of DC power supplies 58.
Part of the external housing 50 includes inputs to the microcontroller 60. One important element that could be used as a user interface to the microcontroller 60 would be a keypad 66, such as a set of bubble or membrane switches that have the numbers 0-9, as well as an “ENTER” key. Other keys could be included as part of keypad 66, including a “CANCEL” key, or perhaps a decimal point key.
The “single-housing” stand-alone unit 150 of FIG. 10 can incorporate all of the electrical and electronic components that are described herein with respect to FIGS. 5-7, including any optional features, such as the high voltage power supply and certain sensors used only in particular configurations of the present invention. Unless a different type of electrical power source is provided, there would be a need for a set of batteries 52, as illustrated in FIG. 10. There may be no need for an extended flat cable (such as flat cable 40 on FIG. 1) to carry electrical signals to and from the electronic controller on the printed circuit board 54, although some type of electrical conductors would be typically used for that purpose within the unitary device 150.
FIGS. 11 and 12 are flow charts illustrating some of the logical operations that are performed by a controller for use with the present invention when used in dispensing or applying a benefit composition. The term “benefit composition” will also be referred to herein as a “fabric treatment composition.” In the flow charts of FIG. 11, the temperature within the chamber is used to determine when the fabric treatment composition should begin to be applied, whereas in FIG. 12, the elapsed time of the drying cycle is used to determine when the fabric treatment composition should start being applied.
Referring now to FIG. 11, a flow chart 200 begins at a step 210 that represents the start of a drying cycle of a drying apparatus, for example, a clothes dryer. The temperature inside the chamber of the dryer is repetitively measured at a step 212, and this would typically be accomplished by some type of logic processing device (such as a microcontroller or a microprocessor) that executes instructions and, in this circumstance, will sequentially execute steps that sample an input signal from a temperature sensor (e.g., sensor 48 on FIG. 5) and convert that signal to engineering units (in degrees F or degrees C), and after appropriate additional processing, will go back and sample that temperature once again (in a repetitive cycle). In the flow chart 200, this measured or sampled temperature of the dryer is referred to as “TP1 ”.
At step 216, the most previous sampled temperature value would not be the “maximum” value for this portion of the drying cycle. Instead, the second most previous sampled temperature value would be that “maximum” temperature value, and this value is referred to as “TP2”. At step 216, the maximum temperature TP2 is stored in a memory element (or register) of the controller, or in a separate memory device. This could include the on-board memory of the microcontroller 60 (see FIG. 5). This maximum temperature TP2 is an example of the “first control operating temperature” that was discussed above.
The logic flow now travels to a step 220 where the dryer's temperature is again measured, and the measurement in this circumstance results in a variable named “TP3”. TP3 is the same physical parameter as the dryer's temperature TP1, but the temperature is sampled and stored under this variable name TP3 only after the “maximum” temperature TP2 has been stored in step 216. (Note, this convention for naming the temperature variables is used merely for this description, and the actual software code may use the same variable name throughout the entire process.)
Assuming for this example that the heating element is a binary device, then while it is energized, the temperature will tend to continually increase within the drying chamber. Once the heating element is turned off, then the temperature will begin to decrease (although there could be some overshoot). During a single drying cycle, the heating element may be turned on and off several times, in which case a temperature versus time graph would have the appearance of a sawtooth waveform, in which an increasing slope (assuming temperature is the Y-axis and time is the X-axis) would occur when the heating element is turned on, and a decreasing slope when the heating element is turned off. During this sawtooth waveform interval, the overall temperature versus time chart will have the appearance of a plateau, in which the chart exhibits a relatively long increasing slope during the beginning of the drying cycle, then it reaches the plateau region (exhibiting the sawtooth waveform), and at the end of the drying cycle the slope will continually decrease on the “far” side of the plateau.
Assuming, however, that the heating element control status is not known to the fabric treatment composition dispensing controller, which would be the case if the dispensing apparatus was a self-contained unit that is not in communication with the dryer's controller, then another means of determining the end of the heating cycle would be required. One way of determining the end of a heating cycle (or “heating event”) would be to determine the maximum and minimum temperatures that occur during the sawtooth waveform portion of the heating cycle, also referred to above as the “plateau region.” If, for example, the internal temperature of the dryer's chamber will rise to a maximum temperature TP2, and then fall to a momentary “minimum” temperature that is about 10-15° C. lower than TP2, then the controller for the dispensing apparatus could determine when to begin applying the fabric treatment composition, which is after the dryer's internal temperature falls below maximum TP2 temperature, less the 10-15° C. “minimum” temperature. These sawtooth minimum and maximum temperature values can be considered a single differential temperature value, and that type of differential temperature will be referred to herein by a variable “TDIFF1”. Some extra tolerance could be built in to the TDIFF1 value, so that, for example, if most home dryers rise and fall by approximately 15° C. during the plateau region of the drying cycle, then the value for TDIFF1 could be set to 20° C.
In general, the dryer's internal temperature will also be referred to as its “operating temperature” herein, which can be determined by a temperature sensor, such as the temperature sensor 48 on FIG. 5. The typical internal temperature of the dryer would physically be the air temperature within the drying chamber, and the placement of the temperature sensor (at the front wall, rear wall, top wall, or elsewhere) could affect the temperature setpoints selected when using the present invention. It also could be possible to monitor the temperature of the fabric articles themselves, and that physical parameter could be used as the “operating temperature,” if desired.
The temperature sensor can be of any typical type, such as a thermistor, a thermocouple, or perhaps a platinum RTD. Moreover, the temperature sensor could also be more of an “on-off” device in some of the applications of the present invention. For example, a thermostat could be used to determine when a predetermined operating temperature has been achieved. In some applications of the present invention, the thermostat could be designed with a certain amount of hysteresis, so that it will change state (e.g., open) at a first temperature (e.g., at “TP2” on FIG. 11), then change state again (e.g., close) at a second temperature (e.g., at “TP3” on FIG. 11). Additional logic might be required when using an on-off, or digital, temperature sensing device.
It will be understood that the dryer's operating temperature is essentially being “continuously” monitored by the controller of the present invention, for example, the microcontroller 60 on FIG. 5. In most sequential processing devices, the software will execute instructions one at a time, and in the flow chart 200 the temperature TP1 is sampled at one executable instruction of the software, and then sampled again at a later time when the software “loops” back to that same (or a similar) executable instruction. This looping action often occurs so quickly that it appears to be virtually instantaneous, such that the controller seems to be continuously monitoring the temperature. However, it is not necessary to literally monitor the temperature (and other inputs) at each moment of time, because the controller operates much more quickly than any possible “quick” variations in the temperature, for example.
On the other hand, if the temperature sensor has a digital output (such as a thermostat with an electromechanical switching contact), then the effect of that type of sensor would literally be one of “continuously” monitoring the operating temperature of the dryer. (It would change state precisely when it determined that it should do so, and would not be “waiting” for a software instruction to first be executed.) Of course, the controller would not necessarily be continuously monitoring the digital input signal produced by the thermostat, since a sequential processing device would have many other tasks to perform. In essence, the controller typically would be sampling both digital and analog input data in some type of looping action, all under the control of the software instructions. However, if portions of the controller of the present invention are primarily made of discrete logic elements, using voltage comparators or parallel digital input gates (e.g., without a microprocessor), then the temperature in essence could be monitored in a continuous fashion, if desired.
As noted above, the controller of the present invention could be constructed as a sequential processing device, a parallel processing device, or perhaps as a logic state machine. If a sequential device is used (such as the microcontroller 60), it will be understood that its software instructions could be arranged in a manner so that it acts as a multi-tasking device. In that manner, it would be executing multiple routines virtually in real time by “jumping” from one routine to another in short time segments, even though perhaps none of those routines had been completed. An example of this would occur during the looping action around steps 212 and 214 of flow chart 200, while the system controller is “waiting” for the dryer's temperature to decrease. If the microcontroller 60 were performing only that task, then it would not be able to do anything else; that type of “real time programming” would not be efficient.
Referring again to FIG. 11, a flow chart 250 again starts with a drying cycle “Start” command at a step 260, and then measures the temperature in the dryer at a step 262. In flow chart 260, this real time temperature value is referred to as “TP11”.
The logic flow now travels to a decision step 264 which determines if the temperature has decreased since a previous temperature sample, and if the answer is NO, the logic flow travels back to step 262 to once again sample the dryer's internal temperature TP11. However, if the temperature has decreased, the logic flow will travel out the YES output from step 264, and the second most previous value of the temperature TP11 will be stored at a step 266 as the “maximum temperature” TP12. So far in flow chart 250, these steps duplicate the logic of the flow chart 200.
A variation on the theme for flow chart 250 would be to allow the maximum temperature (TMAX) to be adjustable by a user, for example, using the keypad 66 (see FIG. 5). With a user entry being possible, the software that is executed by the controller of the device 10 would typically have a default value, so that the apparatus will automatically operate whether or not a user has entered any type of data. In that situation, a value for TMAX would already exist in the memory device for the controller (such as the microcontroller 60), and the numeric value for the maximum temperature, for example, could be as high as 70° C., or even perhaps as low as 25° C. The TMAX value would mainly depend upon the type of volatile material that is going to be dispensed by the fabric article treating system 10.
In another variation of the flow charts 200 and 250, the maximum temperature (TP2 or TP12) could itself have minimum or maximum values before being accepted as the “true” maximum temperature for a particular drying cycle. For example, if the fabric article treating system 10 is manufactured to work with a certain series of dryers that would typically heat their chambers to at least 80° C., and if the maximum temperature achieved during an operation is only about 50° C., then the controller may come to the conclusion that the dryer is not operating properly. In that circumstance, the controller could attempt to signal an error to the user by turning on an LED, for example. In addition, the controller can be programmed so as to prevent the fabric treatment composition from being applied at all in this circumstance (if that is the desired result). This type of decision can be left to the system designer, because it might also be desired to allow the fabric treatment composition to be dispensed, even though the fabric articles may not have been completely dried at the end of the drying cycle (since the “correct” maximum temperature was never achieved).
Referring now to FIG. 12, a flow chart 300 begins by setting the “drying cycle” timer at a step 310. The value for the drying cycle timer is stored in a variable called TM1 on this flow chart 300. The drying cycle timer would preferably be set to the same time interval as the controller for the drying apparatus itself. If the fabric article treating system has its controller integrally mated with the dryer's controller, then this drying cycle time could be immediately known to the controller (such as microcontroller 60) for the fabric article treating system 10. However, if the fabric article treating system 10 is a self-contained device that stands separate and is not in communication with the controller of the dryer itself, then a separate method must be used for entering the drying cycle timer value TM1. The keypad 66 on FIG. 5 would be a means for entering the drying cycle time, in which the user could manually key in the number of minutes for the drying cycle, for example. Again, the number of minutes entered on the keypad 66 would preferably match up to the number of minutes that the user would enter on the dryer's controller. An alternative timer entry device could instead be used, such as a dial device that has a rotating knob, for example.
Once the drying cycle timer value TM1 has been set, the drying cycle can start at a step 312. A decision step 320 now determines if the elapsed time for the drying cycle itself has exceeded a predetermined time interval. In step 320, the time threshold is referred to as K times TM1, in which the coefficient K represents a percentage of the entire drying cycle time TM1. In one mode of the invention, it is desirable to prevent the fabric treatment composition from being applied until the final 25% of the drying cycle time TM1. In that situation, the coefficient K would be set to 75%. This could be an internal default setting, or the system designer could also allow the user to set the coefficient K by use of the keypad 66 (although the next flow chart 330 may be somewhat more “user-friendly,” since it allows the user to enter numbers in units of time, rather than as a percentage).
If the elapsed time has not exceeded K×TM1, then the logic flow travels back to the top of decision step 320 where it continues to take time samples until the elapsed time actually does exceed that value K×TM1. Once that occurs, then the logic flow travels out the YES result to a step 322. At that point, the fabric treatment composition begins being applied into the dryer's chamber, and this routine ends.
The logic of flow chart 300 could be used to either supplement or replace the logic discussed above in reference to FIG. 11. For example, if the dryer is going to be used in a “fluff” or a “refluff” mode, then the heating element of the dryer may not be energized at all. In that situation, one could not rely on any type of increasing or decreasing temperature readings, as they would have no value in determining exactly where the dryer's operating cycle currently stands. Instead, the elapsed time would be a much more valuable parameter for making determinations about when to apply the fabric treatment composition.
Furthermore, the drying cycle flow chart 300 could also supplement the flow chart 200 in situations where the dryer is supposed to increase its internal temperature, but for some reason became “short-cycled” such that its normal maximum temperature was never reached, or was used in a mode that did not energize the heating element to its normal extent (which might prevent the normal maximum temperature from being reached within a certain time limit). In that situation, the logic of flow chart 300 could be used to supplement the logic of flow chart 200, such that the elapsed time threshold K×TM1 would occur before the temperature specifications have been achieved for either decision step 222 or 274 on flow chart 200 or 250. In that situation, the fabric treatment composition could be applied according to the logic of decision step 320 on flow chart 300, regardless of the actual temperatures inside the dryer. If the maximum temperatures normally expected do not actually occur, then the actual temperature might be sufficiently low to allow the volatile material to be dispensed without being wasted in a “high temperature” chamber that otherwise might exist.
A flow chart 330 begins with a step 340 in which the drying cycle timer is set by the user, and is referred to as the variable TM11. In step 340, the user also sets a “dispensing time” timer, which is given the variable name TM12 on flow chart 300. The logic in this flow chart 330 allows the user to set an actual time in engineering units (e.g., minutes or seconds) that will determine the beginning of the application for the fabric treatment composition into the dryer's chamber. For example, if the drying cycle timer is set to sixty minutes (for TM11), and if the dispensing time timer is set to twenty minutes (for TM12), then the dryer will operate for forty minutes without any fabric treatment composition being applied, then with twenty minutes remaining in the drying cycle time, the composition will begin being applied.
The logic of flow chart 300 is as follows: at a step 342 the drying cycle starts. A decision step 344 now determines if the elapsed time has exceeded the difference between the times TM11 and TM12. If the answer is NO, the logic flow travels back to the beginning of step 344, which keeps “looping” until a sufficient elapsed time occurs so that the result finally becomes YES.
In general, the elapsed time during a drying cycle will also be referred to as the dryer's “operating time” herein, and can be determined by a virtually any type of time-keeping device. If a digital processing device is used (such as microcontroller 60 on FIG. 5), then a high-frequency clock typically will be included in the circuit design to cause the processing device to execute software instructions for each of the “clock cycles.” The system clock's cycling rate can be readily divided down (by digital dividers) to a lower frequency to create “real time” intervals, such as one second or one-tenth second time periods (as noted above), and the dryer's operating time can be based upon such real time intervals. On the other hand, a separate clocking device could be provided, if desired, such as a digital counter that receives clock pulses from a separate pulse generator.
It will be understood that the dryer's operating time is essentially being “continuously” monitored by the controller of the present invention (for example, the microcontroller 60 on FIG. 5). In most sequential processing devices, the software will execute instructions one at a time, and in the flow chart 300 the elapsed time could be sampled at one executable instruction of the software (e.g., at step 320), and then sampled again at a later time when the software “loops” back to that same (or a similar) executable instruction. This looping action often occurs so quickly that it appears to be virtually instantaneous, such that the controller seems to be continuously monitoring the time, when in reality the elapsed time is being “sampled” according to the rate at which the looping action occurs.
A decision step 370 now determines if the elapsed time has exceeded a preset value as a time threshold that is related to the total drying cycle time TM21. This preset time uses a coefficient, much like the logic in step 320 of flow chart 300. In this flow chart 350, the coefficient is referred to as “K1”, and the time threshold is referred to as K1 times TM21. K1 would normally be set as a percentage, and it is used for the final amount of the drying cycle. For example, if K1 is set to 75%, then the fabric treatment composition would be dispensed or applied during the final 25% of the drying cycle time interval TM21.
If the elapsed time has not exceeded this threshold K1×TM21, then the logic flow is directed back to the top of this decision step 370, where it continues to “loop” until a sufficient elapsed time has occurred to finally achieve the YES result. The logic flow now travels to a step 372 that begins applying the fabric treatment composition to the dryer's chamber.
The logic flow now travels to a decision step 380 that determines if the elapsed time has exceeded a different time threshold, referred to on flow chart 350 as the coefficient K2 times the drying cycle time TM21. This coefficient K2 would be a smaller number than the coefficient K1. If the result is NO, then the logic flow travels back to the top of decision step 380 where the logic continues to “loop” until a sufficient elapsed time occurs so that the YES result is finally achieved. Once that occurs, a step 382 stops the application of the fabric treatment composition into the dryer's chamber, which is the end of this routine.
Flow chart 350 thereby allows a user (or the system designer) to set both start and stop points during the drying cycle, and moreover, these starting and stopping coefficients can be pre-loaded into the software as default values. For example, if K1 equals 25% and K2 equals 0.75%, then the fabric treatment composition will start being applied at a point 75% into the elapsed time of the drying cycle, and the fabric treatment composition will stop being applied at an elapsed time of 99.25% of the entire drying cycle time TM21. This allows the fabric material inside the drying chamber to have a final tactile quality of being “dry” as opposed to feeling somewhat damp or wet. In other words, if the fabric treatment composition is dispensed completely to the end of the drying cycle, and if the user immediately opens the dryer door and grasps the fabric articles, there may be a somewhat wet or damp tactile quality to these articles. The logic of flow chart 350 would likely prevent that type of result. It may be desirable to limit the value of K2 so that it can never be set all the way to 100%.
One optional aspect of the present invention is to provide the fabric treatment composition at two different time intervals during the drying cycle. For example, the fabric treatment composition could be applied fairly early during the drying cycle as a fabric softener; then at a later time (e.g., during the “cool-down” phase) the fabric treatment composition could be applied as a perfume, or perhaps to provide some other type of beneficial property or result. Such a dispensing program can be referred to as a “split cycle” of applying (e.g., spraying) the fabric treatment composition, since there typically may be a time interval during which no dispensing at all occurs during the drying cycle, after the first portion of spraying/dispensing has terminated.
The principles of the present invention nevertheless apply to a split cycle of dispensing, in which the volatile characteristics of the fabric treatment composition are best utilized near the “end” of the entire drying cycle of the drying apparatus. If that is a desired result, then the logical operations described in the flow charts of FIGS. 11 and 12 provide an exemplary set of processing steps that may be used to implement such dispensing or applying of the fabric treatment composition to the fabric articles.
It should be noted that there may be circumstances in which there would be no elapsed time interval between the two “split” dispensing cycles. This could occur, for example, if a very short drying cycle time has been selected by the user of the drying apparatus, or if a very small load of fabric articles has been placed into the drying chamber of the drying apparatus. In one of those circumstances, it may be possible for the first spraying event and the second spraying event to overlap, such that there would be no “true” split interval spraying procedure, because the first spraying event would not have terminated before it became time to begin the second spraying event. Thus there might not be an elapsed time interval during which no spraying at all would be occurring. However, with regard to the processing logic which determines “when” to apply the fabric treatment composition near the “end” of the drying cycle (such as the logic of the flow charts on FIGS. 11 and 12), the same decisions would still be made based upon the proper time and/or temperature input information. In other words, the controller's decision to “start” the “second spraying event” would have to be taken, otherwise the fabric treatment composition would stop being applied at the end of the “first spraying event” of this example, and the second spraying event might not begin at all.
