Title: Systems and methods for adjusting a washing operation based on feedback from a drying operation

Description:
FIELD OF THE INVENTION 
     The present subject matter relates generally to laundry treatment appliances, and more particularly to optimizing operating parameters of washing machine appliances. 
     BACKGROUND OF THE INVENTION 
     Conventional laundry treatment appliances perform a washing operation and/or a drying operation, typically in succession. For instance, a washing machine appliance may perform the washing operation and the laundry load may be transferred to a dryer appliance to perform the drying operation. The washing operation may incorporate a predetermined set of parameters, including one or more cycles of washing, rinsing, spinning, and the like. Similarly, the drying operation may incorporate a predetermined set of parameters, including a cycle time, an operational temperature, and a requested dryness level. Users of these laundry treatment appliances may wish to modify one or more of these parameters in order to increase a washing efficiency, a drying efficiency, or a total length of time for each of the washing operation and the drying operation 
     For instance, certain cycles within the washing operation may be adjusted to better prepare the laundry load for the drying operation and subsequently reduce the drying time. Currently, users typically increase a total time or a level of heat of the drying operation, which can damage certain laundry loads. Thus, further improvements are necessary to properly assess and manipulate the set of washing parameters to achieve a desirable total washing and drying time. 
     Accordingly, a laundry treatment appliance or assembly that obviates one or more of the above-described drawbacks would be beneficial. Particularly, a method of operating a laundry treatment appliance utilizing user feedback would be useful.

System configurations may vary, other communication devices may be used to communicate directly or indirectly with one or more laundry appliances, other communication protocols and steps may be implemented, etc. These variations and modifications are contemplated as within the scope of the present subject matter. 
     Referring now also to  FIGS.  2  and  3   , washing machine appliance  52  will be described according to an exemplary embodiment of the present subject matter. Specifically, these figures illustrate an exemplary embodiment of a vertical axis washing machine appliance  52 . Specifically,  FIGS.  1  and  2    illustrate perspective views of washing machine appliance  52  in a closed and an open position, respectively.  FIG.  3    provides a side cross-sectional view of washing machine appliance  52 . Washing machine appliance  52  generally defines a vertical direction V, a lateral direction L, and a transverse direction T, each of which is mutually perpendicular, such that an orthogonal coordinate system is generally defined. 
     While described in the context of a specific embodiment of vertical axis washing machine appliance  52 , it should be appreciated that vertical axis washing machine appliance  52  is provided by way of example only. It will be understood that aspects of the present subject matter may be used in any other suitable washing machine appliance, such as a horizontal axis washing machine appliance. Indeed, modifications and variations may be made to washing machine appliance  52 , including different configurations, different appearances, and/or different features while remaining within the scope of the present subject matter. 
     Washing machine appliance  52  has a cabinet  102  that extends between a top portion  104  and a bottom portion  106  along the vertical direction V, between a first side (left) and a second side (right) along the lateral direction L, and between a front and a rear along the transverse direction T. As best shown in  FIG.  3   , a wash tub  108  is positioned within cabinet  102 , defines a wash chamber  110 , and is generally configured for retaining wash fluids during an operating cycle. Washing machine appliance  52  further includes a primary dispenser  112  ( FIG.  2   ) for dispensing wash fluid into wash tub  108 . The term “wash fluid” refers to a liquid used for washing and/or rinsing articles during an operating cycle and may include any combination of water, detergent, fabric softener, bleach, and other wash additives or treatments. 
     In addition, washing machine appliance  52  includes a wash basket  114  that is positioned within wash tub  108  and generally defines an opening  116  for receipt of articles for washing. More specifically, wash basket  114  is rotatably mounted within wash tub  108  such that it is rotatable about an axis of rotation A. According to the illustrated embodiment, the axis of rotation A is substantially parallel to the vertical direction V. In this regard, washing machine appliance  52  is generally referred to as a “vertical axis” or “top load” washing machine appliance  52 . However, it should be appreciated that aspects of the present subject matter may be used within the context of a horizontal axis or front load washing machine appliance as well. As used herein, terms of approximation, such as “approximately,” “substantially,” or “about,” refer to being within a ten percent margin of error. 
     As illustrated, cabinet  102  of washing machine appliance  52  has a top panel  118 . Top panel  118  defines an opening ( FIG.  2   ) that coincides with opening  116  of wash basket  114  to permit a user access to wash basket  114 . Washing machine appliance  52  further includes a door  120  which is rotatably mounted to top panel  118  to permit selective access to opening  116 . In particular, door  120  selectively rotates between the closed position (as shown in  FIGS.  1  and  3   ) and the open position (as shown in  FIG.  2   ). In the closed position, door  120  inhibits access to wash basket  114 . Conversely, in the open position, a user can access wash basket  114 . A window  122  in door  120  permits viewing of wash basket  114  when door  120  is in the closed position, e.g., during operation of washing machine appliance  52 . Door  120  also includes a handle  124  that, e.g., a user may pull and/or lift when opening and closing door  120 . Further, although door  120  is illustrated as mounted to top panel  118 , door  120  may alternatively be mounted to cabinet  102  or any other suitable support. 
     As best shown in  FIGS.  2  and  3   , wash basket  114  further defines a plurality of perforations  126  to facilitate fluid communication between an interior of wash basket  114  and wash tub  108 . In this regard, wash basket  114  is spaced apart from wash tub  108  to define a space for wash fluid to escape wash chamber  110 . During a spin cycle, wash fluid within articles of clothing and within wash chamber  110  is urged through perforations  126  wherein it may collect in a sump  128  defined by wash tub  108 . Washing machine appliance  52  further includes a pump assembly  130  ( FIG.  3   ) that is located beneath wash tub  108  and wash basket  114  for gravity assisted flow when draining wash tub  108 . 
     An impeller or agitation element  132  ( FIG.  3   ), such as a vane agitator, impeller, auger, oscillatory basket mechanism, or some combination thereof is disposed in wash basket  114  to impart an oscillatory motion to articles and liquid in wash basket  114 . More specifically, agitation element  132  extends into wash basket  114  and assists agitation of articles disposed within wash basket  114  during operation of washing machine appliance  52 , e.g., to facilitate improved cleaning. In different embodiments, agitation element  132  includes a single action element (i.e., oscillatory only), a double action element (oscillatory movement at one end, single direction rotation at the other end) or a triple action element (oscillatory movement plus single direction rotation at one end, single direction rotation at the other end). As illustrated in  FIG.  3   , agitation element  132  and wash basket  114  are oriented to rotate about axis of rotation A (which is substantially parallel to vertical direction V). 
     As best illustrated in  FIG.  3   , washing machine appliance  52  includes a drive assembly  138  in mechanical communication with wash basket  114  to selectively rotate wash basket  114  (e.g., during an agitation or a rinse cycle of washing machine appliance  52 ). In addition, drive assembly  138  may also be in mechanical communication with agitation element  132 . In this manner, drive assembly  138  may be configured for selectively rotating or oscillating wash basket  114  and/or agitation element  132  during various operating cycles of washing machine appliance  52 . 
     More specifically, drive assembly  138  may generally include one or more of a drive motor  140  and a transmission assembly  142 , e.g., such as a clutch assembly, for engaging and disengaging wash basket  114  and/or agitation element  132 . According to the illustrated embodiment, drive motor  140  is a brushless DC electric motor, e.g., a pancake motor. However, according to alternative embodiments, drive motor  140  may be any other suitable type or configuration of motor. For example, drive motor  140  may be an AC motor, an induction motor, a permanent magnet synchronous motor, or any other suitable type of motor. In addition, drive assembly  138  may include any other suitable number, types, and configurations of support bearings or drive mechanisms. 
     Referring still to  FIGS.  1  through  3   , a control panel  150  with at least one input selector  152  ( FIG.  1   ) extends from top panel  118 . Control panel  150  and input selector  152  collectively form a user interface input for operator selection of machine cycles and features. A display  154  of control panel  150  indicates selected features, operation mode, a countdown timer, and/or other items of interest to appliance users regarding operation. 
     Operation of washing machine appliance  52  is controlled by a controller or processing device  62  that is operatively coupled to control panel  150  for user manipulation to select washing machine cycles and features. In response to user manipulation of control panel  150 , controller  62  operates the various components of washing machine appliance  52  to execute selected machine cycles and features. According to an exemplary embodiment, controller  62  may include a memory and microprocessor, such as a general or special purpose microprocessor operable to execute programming instructions or micro-control code associated with methods described herein. Alternatively, controller  62  may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software. 
     Control panel  150  and other components of washing machine appliance  52  may be in communication with controller  62  via one or more signal lines or shared communication busses. Additionally or alternatively, washing machine appliance  52  may include a door sensor or door switch  156 . Door sensor  156  may be provided at or near opening  116  and may detect an opening or a closing of door  120 . For instance, door sensor  156  may be a magnetic sensor, an optic sensor, a Hall sensor, a reed sensor, or the like. It should be noted that one or more sensors may be included, and that any combination of sensors or switches may be incorporated as door sensor  156 . 
     During operation of washing machine appliance  52 , laundry items are loaded into wash basket  114  through opening  116 , and washing operation is initiated through operator manipulation of input selectors  152 . Wash basket  114  is filled with water and detergent and/or other fluid additives via primary dispenser  112 . One or more valves can be controlled by washing machine appliance  52  to provide for filling wash tub  108  and wash basket  114  to the appropriate level for the amount (or number) of articles being washed and/or rinsed. By way of example for a wash mode, once wash basket  114  is properly filled with fluid, the contents of wash basket  114  can be agitated (e.g., with agitation element  132  as discussed previously) for washing of laundry items in wash basket  114 . 
     More specifically, referring again to  FIG.  3   , a water fill process will be described according to an exemplary embodiment. As illustrated, washing machine appliance  52  includes a water supply conduit  160  that provides fluid communication between a water supply source  162  (such as a municipal water supply) and a discharge nozzle  164  for directing a flow of water into wash chamber  110 . In addition, washing machine appliance  52  includes a water fill valve or water control valve  166  which is operably coupled to water supply conduit  160  and communicatively coupled to controller  62 . In this manner, controller  62  may regulate the operation of water control valve  166  to regulate the amount of water within wash tub  108 . In addition, washing machine appliance  52  may include one or more pressure sensors  170  for detecting the amount of water and or clothes within wash tub  108 . For example, pressure sensor  170  may be operably coupled to a side of tub  108  for detecting the weight of wash tub  108 , which controller  62  may use to determine a volume of water in wash chamber  110  and a subwasher load weight. 
     After wash tub  108  is filled and the agitation phase of the wash cycle is completed, wash basket  114  can be drained, e.g., by drain pump assembly  130 . Laundry articles can then be rinsed by again adding fluid to wash basket  114  depending on the specifics of the cleaning cycle selected by a user. The impeller or agitation element  132  may again provide agitation within wash basket  114 . One or more spin cycles may also be used as part of the cleaning process. In particular, a spin cycle may be applied after the wash cycle and/or after the rinse cycle in order to wring wash fluid from the articles being washed. During a spin cycle, wash basket  114  is rotated at relatively high speeds to help wring fluid from the laundry articles through perforations  126 . After articles disposed in wash basket  114  are cleaned and/or washed, the user can remove the articles from wash basket  114 , e.g., by reaching into wash basket  114  through opening  116 . 
     Referring now to  FIG.  4   , a perspective view of dryer appliance  54  is provided with a portion of a cabinet or housing  202  of dryer appliance  54  removed in order to show certain components of dryer appliance  54 . While described in the context of a specific embodiment of dryer appliance  54 , using the teachings disclosed herein it will be understood that dryer appliance  54  is provided by way of example only. Other dryer appliances having different appearances and different features may also be utilized with the present subject matter as well. Dryer appliance  54  defines a vertical direction V, a lateral direction L, and a transverse direction T. The vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular and form an orthogonal direction system. 
     Cabinet  202  includes a front panel  204 , a rear panel  206 , a pair of side panels  208  spaced apart from each other by front and rear panels  204  and  206 , a bottom panel  210 , and a top cover  212 . Within cabinet  202  is a drum or container  216  mounted for rotation about a substantially horizontal axis, e.g., that is parallel or substantially parallel to the lateral direction L. Drum  216  defines a chamber  214  for receipt of articles, e.g., clothing, linen, etc., for drying. Drum  216  extends between a front portion and a back portion, e.g., along the lateral direction L. 
     A motor  220  is configured for rotating drum  216  about the horizontal axis, e.g., via a pulley and a belt (not shown). Drum  216  is generally cylindrical in shape, having an outer cylindrical wall or cylinder and a front flange or wall that defines an entry  222  of drum  216 , e.g., at the front portion of drum  216 , for loading and unloading of articles into and out of chamber  214  of drum  216 . A plurality of tumbling ribs  224  are provided within chamber  214  of drum  216  to lift articles therein and then allow such articles to tumble back to a bottom of drum  216  as drum  216  rotates. Drum  216  also includes a back or rear wall, e.g., such that drum  216  is rotatable on its rear wall as will be understood by those skilled in the art. A duct  226  is mounted to the rear wall of drum  216  and receives heated air that has been heated by a heating assembly or system  240 . 
     Motor  220  is also in mechanical communication with an air handler  230  such that motor  220  rotates air handler  230 , e.g., a centrifugal fan. Air handler  230  is configured for drawing air through chamber  214  of drum  216 , e.g., in order to dry articles located therein as discussed in greater detail below. In alternative exemplary embodiments, dryer appliance  54  may include an additional motor (not shown) for rotating air handler  230  independently of drum  216 . 
     Drum  216  is configured to receive heated air that has been heated by a heating assembly  240 , e.g., in order to dry damp articles disposed within chamber  214  of drum  216 . Heating assembly  240  includes a heating element (not shown), such as a gas burner or an electrical resistance heating element, for heating air. As discussed above, during operation of dryer appliance  54 , motor  220  rotates drum  216  and air handler  230  such that air handler  230  draws air through chamber  214  of drum  216  when motor  220  rotates. In particular, ambient air (identified herein generally by reference numeral  242 ) enters heating assembly  240  via an entrance  244  due to air handler  230  urging such ambient air into entrance  244 . Such ambient air is heated within heating assembly  240  and exits heating assembly  240  as heated air  242 . Air handler  230  draws such heated air through duct  226  to drum  216 . The heated air enters drum  216  through an outlet  246  of duct  226  positioned at the rear wall of drum  216 . 
     Within chamber  214 , the heated air can accumulate moisture, e.g., from damp articles disposed within chamber  214 . In turn, air handler  230  draws humid air through a trap duct  248  which contains a screen filter (not shown) which traps lint particles. Such humid air then passes through trap duct  248  and air handler  230  before entering an exhaust conduit  250 . From exhaust conduit  250 , such humid air passes out of dryer appliance  54  through a vent  252  defined by cabinet  202 . After the clothing articles have been dried, they are removed from the drum  216  via entry  222 . A door  260  provides for closing or accessing drum  216  through entry  222 . 
     A user interface panel  270  is positioned on a cabinet backsplash and includes a cycle selector knob  272  that is in communication with a processing device or controller (such as a controller  62 ). Signals generated in controller  62  operate motor  220 , air hander,  230 , and heating assembly  240  in response to the position of selector knobs  272 . User interface panel  270  may further conclude additional indicators, a display screen, a touch screen interface  174 , etc. for providing information to a user of the dryer appliance  54  and receiving suitable operational feedback. Alternatively, a touch screen type interface, knobs, sliders, buttons, speech recognition, etc., mounted to cabinet backsplash or at any other suitable location to permit a user to input control commands for dryer appliance  54  and/or controller  62 . 
     Controller  62  may include memory and one or more processing devices such as microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of dryer appliance  54 . The memory can represent random access memory such as DRAM, or read only memory such as ROM or FLASH. The processor executes programming instructions stored in the memory. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller  62  may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software. 
     In general, controller  62  is in operative communication with various components of dryer appliance  54 . In particular, controller  62  is in operative communication with motor  220  and heating assembly  240 . Thus, upon receiving an activation signal from cycle selector knob  272 , controller  62  can activate motor  220  to rotate drum  216  and air handler  230 . Controller  62  can also activate heating assembly  240  in order to generate heated air for drum  216 , e.g., in the manner described above. 
     Controller  62  is also in communication with a thermal or temperature sensor  280 , e.g., a thermocouple or thermistor. Temperature sensor  280  is configured for measuring a temperature of heated air within duct  226 . Temperature sensor  280  can be positioned at any suitable location within dryer appliance  54 . For example, temperature sensor  280  may be positioned within or on duct  226 . Controller  62  can receive a signal from temperature sensor  280  that corresponds to a temperature measurement of heated air within duct  226 , e.g., a temperature measurement of heated air exiting duct  226  at outlet  246 . 
     Now that the construction of system  50 , washing machine appliance  52 , dryer appliance  54 , and external communication system  60  have been presented according to exemplary embodiments, an exemplary method  300  of operating a system of laundry appliances will be described. Although the discussion below refers to the exemplary method  300  of operating system  50  to adjust the operation of washing machine appliance  52 , one skilled in the art will appreciate that the exemplary method  300  is applicable to the monitoring and control of any suitable system of laundry appliances. In exemplary embodiments, the various method steps as disclosed herein may be performed by controllers  62 , remote server  68 , and/or a separate, dedicated controller. 
     Referring generally to  FIG.  5   , a method of operating a laundry treatment assembly (e.g., laundry system  50 ) will be described in detail. According to exemplary embodiments, a user may perform a washing operation within a washing machine appliance (e.g., washing machine appliance  52 ). The washing operation may be similar to the washing operation described above. For instance, the washing operation may include a supply cycle for supplying water and detergent to the basket, an agitation cycle, a drain cycle, a rinse cycle, and one or more spin cycles. In particular, a final spin cycle may be performed at the end of the washing operation. The final spin cycle may be performed according to a first set of parameters. For instance, the first set of parameters may include a rotational speed of a drum (e.g., wash basket  114 ) of the washing machine appliance, a length of time of the spin cycle, etc. The controller (e.g., controller  62 ) may register the first set of parameters as a first set of parameters of a most recently performed washing operation. It should be noted that method  300  may or may not include the pre-step of performing the washing operation. For instance, the controller may have a set of parameters already stored within its memory from a previous washing operation. 
     At step  302 , method  300  may include performing a drying operation within the dryer appliance. In detail, a drying operation may be performed on a laundry load within a dryer appliance (e.g., dryer appliance  54 ). As discussed above, the dryer appliance may be part of a laundry treatment assembly or system, or may be part of a combination washing machine/dryer appliance. The drying operation may be performed according to a set of drying parameters. For instance, the user may insert the laundry load into a drum (e.g., drum  216 ) of the dryer appliance to be dried. The user may then select one or more options, e.g., from a user interface panel (e.g., user interface panel  270 ). Additionally or alternatively, the user may select one or more options for the drying operation from a mobile device in wireless communication with the dryer appliance. 
     In detail, the user may select a dryness level. The dryness level may be selected from a plurality of options, such as very dry, more dry, normal, less dry, way less dry, or the like. Additionally or alternatively, the user may select a length of time for which the drying operation is to perform. The length of time may be presented in predetermined increments. The user may also select a temperature level for the air to be supplied to the drum for the drying operation. For instance, the temperature (or heat level) may be selected from one of no heat, low heat, medium heat, high heat, or the like. Finally, the user may select a predetermined drying operation having preselected parameters. In some embodiments, the dryer appliance may include one or more sensors therein (e.g., humidity sensors, temperature sensors, etc.) which may provide information for the controller to determine when the laundry load has reached an appropriate or desired dryness level. These drying operations may be referred to as “smart drying operations.” 
     At step  304 , method  300  may include receiving user feedback regarding the drying operation. In detail, the controller (e.g., of the laundry system) may register one or more pieces of data indicating user feedback of the drying operation. The data may be regarded as active feedback or passive feedback. For instance, according to at least one embodiment, the controller may transmit a feedback request to the user. The feedback request may be displayed to the user on the user interface panel. Additionally or alternatively, the feedback request may be transmitted to one or more mobile devices of the user (e.g., a mobile phone, a smartwatch, a tablet, etc.). According to at least one embodiment, the user receives a push notification from a mobile application registered to the dryer appliance. 
     The feedback request may include a prompt to provide a rating of the drying operation. For instance, the prompt may include a scale of dryness observed by the user upon completion of the drying operation. The scale may include, for example, choices such as way too dry, too dry, acceptable, too damp, way too damp, or the like. The user may thus input the level of dryness experienced. This may be considered active user feedback regarding the drying operation. 
     In some embodiments, the controller may collect passive user feedback. In detail, the passive user feedback may be determined from inputs (e.g., physical inputs) from the user to the dryer appliance during the drying operation. In at least one example, the controller may monitor an opening and a closing of the door to the dryer appliance during the drying operation. The controller may detect (e.g., via a door sensor such as door sensor  156 ) that the user opens and closes the door one or more times during the drying operation. From this information, the controller may conclude that the user is checking the dampness or dryness level of the laundry load within the dryer appliance. Accordingly, the controller may interpret this feedback as dissatisfaction of the drying operation. This may be referred to as passive user feedback. 
     According to another example, the controller may monitor the user&#39;s inputs to the user interface (e.g., on the dryer appliance or through a mobile application). The inputs may be associated particularly with the drying operation. For instance, the controller may determine that the user regularly presses a button requesting a “more dry” level for the laundry load. Additionally or alternatively, the controller may register inputs such as temperature increases, time increases or decreases, or the like. In another example, during the smart drying operation, the user may press a button for “less time.” Since the smart drying operation has predefined inputs, this time selection may have no effect (e.g., may not reduce the actual run time of the drying operation). Thus, the controller may infer that the user in dissatisfied with the length of time of the drying operation. It should be understood that the user feedback described herein (active and passive) is not exhaustive, and that additional types or methods of receiving user feedback or feedback input would be understood. 
     At step  306 , method  300  may include evaluating a most recently performed spin cycle upon receiving the user feedback. The most recently performed spin cycle may be defined by a first set of parameters (e.g., as described above). In detail, the most recently performed spin cycle may be the final spin cycle performed in a most recent washing operation. As described above, the washing machine appliance may perform the washing operation prior to the dryer appliance performing the drying operation. Accordingly, the controller may store the first set of parameters incorporated into the spin cycle. 
     In at least one embodiment, the evaluating of the most recently performed spin cycle may include determining a rotational speed of the drum during the spin cycle. The washing machine appliance may be capable of rotating (or spinning) the drum (e.g., wash basket  114 ) at various speeds as certain operations dictate. Accordingly, the controller may determine the speed at which the drum was rotated in the most recently performed spin cycle and compare the determined speed to a maximum allowable rotational speed. 
     In another embodiment, the evaluating of the most recently performed spin cycle may include determining a total length of time of the spin cycle. For instance, the controller may measure or detect (e.g., via one or more sensors and or timers) a total length of time for which the spin cycle was performed in the most recently performed washing operation. The detected length of time may be compared to, for instance, a table of time lengths appropriate for certain laundry loads. In some embodiments, the controller may consider one or more of a laundry load size, a laundry load type, a wash level selection, a time of day, or the like when comparing the detected length of time. 
     At step  308 , method  300  may include adjusting one or more parameters of the first set of parameters based on the feedback input to generate a second set of parameters. In detail, the controller may create, develop, or otherwise store an adjusted set of parameters resulting from the user feedback and the evaluation of the most recently performed spin cycle (or washing operation in total). As described above, the one or more parameters may be associated with the spin cycle. In particular, the one or more parameters may be associated with a final spin cycle performed at the conclusion of the washing operation. It should be understood that the one or more parameters may be associated with one or more other cycles involved in the washing operation, as certain embodiments see fit. 
     The controller may thus adjust the rotational speed of the drum. For instance, the controller may register a user feedback that a lower drying time is desired, a total dryness level of the laundry load is desired, or the like. In evaluating the most recently performed spin cycle, the controller may determine that the rotational speed of the drum was below the maximum rotational speed of the drum. Accordingly, the controller may adjust the first set of parameters to increase the rotational speed of the drum during the spin cycle to the maximum rotational speed. It should be understood that the disclosure is not limited to the examples given herein. For instance, in some embodiments, the user feedback may result in a shorter spin cycle time and/or a lower rotational speed of the drum during the spin cycle. 
     According to another embodiment, the controller may adjust the length of time of the spin cycle. For instance, the controller may register the user feedback that a lower drying time is desired, a total dryness level of the laundry load is desired, or the like. In evaluating the most recently performed spin cycle, the controller may determine that a length of time of the spin cycle was inadequate (e.g., in the most recently performed spin cycle). Thus, the controller may adjust the total length of time of the spin cycle in the adjusted set of parameters. It should be noted that additional changes to the operating parameters of the washing operation may be incorporated in addition to or in place of those described herein. Moreover, it should be understood that the adjusted set of parameters may include adjustments to each of the rotational speed and the length of time of the spin cycle. Moreover still, it should be understood that additional cycles or steps within the washing cycle may be adjusted as a result of the user feedback. For one example, the controller may increase a length of time for which a drain pump of the washing machine appliance is left in an open state so as to ensure a complete drainage of the rinse water. 
     At step  310 , method  300  may include incorporating the second set (or adjusted set) of parameters into a spin cycle of a subsequent washing operation. The controller may save the second, or adjusted, set of parameters within a memory thereof. Accordingly, upon the next laundry load inserted for a washing operation, the controller may incorporate the second set of parameters. Advantageously, the laundry load may be in a better condition for drying at the commencement of the drying operation, thus reducing the overall laundry operation time and improving a quality of the laundry load upon completion. 
     It should be noted that the controller receiving the feedback, evaluating the spin cycle, the washing operation, and the drying operation, adjusting the one or more parameters, and incorporating the adjusted set of parameters may be provided within the washing machine appliance, the dryer appliance, a combination of each, or neither. Indeed, the controller may be provided within a connected network or remote server (e.g., network  64 , server  68 ). Thus, it should be understood that the performance of method  300  may be carried out by one or more of the appliances described herein. 
     According to the embodiments described herein, a controller of a laundry treatment assembly may monitor one or more parameters of a washing operation and a drying operation. The controller may receive user feedback upon the completion of a drying operation regarding the performance and satisfaction of the drying operation. The controller may then evaluate a most recently performed washing operation, specifically a spin cycle thereof. The spin cycle may include a first set of operating parameters, including a rotational speed of a drum and a total cycle time of the spin cycle. The controller may then adjust one or more of the parameters to generate a second set of parameters, adjusted from the first set. The second set of parameters may be incorporated into a subsequent washing operation in order to more adequately and efficiently perform the drying operation.
