Description

FIELD OF THE INVENTION

The present subject matter relates generally to laundry appliances, and more particularly to methods of manually operating the same.

BACKGROUND OF THE INVENTION

Washing machine appliances generally include a wash tub for containing water or wash fluid, e.g., water and detergent, bleach, and/or other wash additives. A wash basket is rotatably mounted within the wash tub and defines a wash chamber for receipt of articles for washing, and an agitation element is rotatably mounted within the wash basket. Washing machine appliances are typically equipped to operate in one or more modes or cycles, such as wash, rinse, and spin cycles. For example, during a wash or rinse cycle, the wash fluid is directed into the wash tub in order to wash and/or rinse articles within the wash chamber. In addition, the wash basket and/or the agitation element can rotate at various speeds to agitate or impart motion to articles within the wash chamber, to wring wash fluid from the articles, etc.

Notably, the operation of a washing machine appliance is typically regulated by a controller based on user inputs, automated algorithms, and other inputs. Certain users prefer to have more control over the parameters of a particular operating cycle, while others may desire less interaction, preferring to throw in a load, press start, and allow automated algorithms to determine the appropriate parameters for a wash cycle. However, conventional washing machine control panels provide little versatility to a user in selecting and controlling specific washing parameters, functions, and/or cycles.

Accordingly, a laundry appliance including features for improving user interaction and control would be useful. More specifically, a system and method for permitting user manipulation of a large number of operating parameters to facilitate improved user interaction and control of a wash cycle would be particularly beneficial.

DETAILED DESCRIPTION OF THE INVENTION

Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

FIGS. 1 through 3 illustrate an exemplary embodiment of a vertical axis washing machine appliance 100. Specifically, FIGS. 1 and 2 illustrate perspective views of washing machine appliance 100 in a closed and an open position, respectively. FIG. 3 provides a side cross-sectional view of washing machine appliance 100. Washing machine appliance 100 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 100, it should be appreciated that vertical axis washing machine appliance 100 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 100, including different configurations, different appearances, and/or different features while remaining within the scope of the present subject matter.

Washing machine appliance 100 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 100 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 100 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 100 is generally referred to as a “vertical axis” or “top load” washing machine appliance 100. 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 100 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 100 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 100. 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 100 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 100, 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 100 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 100). 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 100.

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 100 is controlled by a controller or processing device 156 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 156 operates the various components of washing machine appliance 100 to execute selected machine cycles and features. According to an exemplary embodiment, controller 156 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 156 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 100 may be in communication with controller 156 via one or more signal lines or shared communication busses.

During operation of washing machine appliance 100, 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 100 to provide for filling wash tub 108 and wash basket 114 to the appropriate level for the amount 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 100 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 100 includes a water fill valve or water control valve 166 which is operably coupled to water supply conduit 160 and communicatively coupled to controller 156. In this manner, controller 156 may regulate the operation of water control valve 166 to regulate the amount of water within wash tub 108. In addition, washing machine appliance 100 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 156 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 still to FIG. 1, a schematic diagram of an external communication system 180 will be described according to an exemplary embodiment of the present subject matter. In general, external communication system 180 is configured for permitting interaction, data transfer, and other communications with washing machine appliance 100. For example, this communication may be used to provide and receive operating parameters, user instructions or notifications, performance characteristics, user preferences, or any other suitable information for improved performance of washing machine appliance 100.

External communication system 180 permits controller 156 of washing machine appliance 100 to communicate with external devices either directly or through a network 182. For example, a consumer may use a consumer device, such as a mobile phone 184, to communicate directly with washing machine appliance 100. For example, mobile phone 184 may be in direct or indirect communication with washing machine appliance 100, e.g., directly through a local area network (LAN), Wi-Fi, Bluetooth, Zigbee, etc. or indirectly through network 182. In general, mobile phone 184 may be any suitable device for providing and/or receiving communications or commands from a user. In this regard, the consumer device may include mobile phone 184, a tablet, a laptop computer, or another mobile device.

In addition, a remote server 186 may be in communication with washing machine appliance 100 and/or mobile phone 184 through network 182. In this regard, for example, remote server 186 may be a cloud-based server 186, and is thus located at a distant location, such as in a separate state, country, etc. In general, communication between the remote server 186 and the client devices may be carried via a network interface using any type of wireless connection, using a variety of communication protocols (e.g., TCP/IP, HTTP, SMTP, FTP), encodings or formats (e.g., HTML, XML), and/or protection schemes (e.g., VPN, secure HTTP, SSL).

In general, network 182 can be any type of communication network. For example, network 182 can include one or more of a wireless network, a wired network, a personal area network, a local area network, a wide area network, the internet, a cellular network, etc. According to an exemplary embodiment, mobile phone 184 may communicate with a remote server 186 over network 182, such as the internet, to provide user inputs, receive user notifications or instructions, etc. In addition, mobile phone 184 and remote server 186 may communicate with washing machine appliance 100 to communicate similar information.

External communication system 180 is described herein according to an exemplary embodiment of the present subject matter. However, it should be appreciated that the exemplary functions and configurations of external communication system 180 provided herein are used only as examples to facilitate description of aspects of the present subject matter. 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 again generally to FIGS. 1 and 2, control panel 150 and associated methods of operation that may be used to control operation of a washing machine appliance will be described according to an exemplary embodiment. Control panel 150 may include a plurality of control inputs, input selectors, buttons, switches, touch panels, capacitive touch buttons, and other features that permit interaction with the user of washing machine appliance 100. Although an exemplary control panel 150 and control schematic is described herein, it should be appreciated that variations and modifications may be made to control panel 150 while remaining within the scope of the present subject matter. Notably, control panel 150 and/or mobile device 184 may be referred to herein interchangeably as a user interface device.

As shown, control panel 150 may include a set of controls that make up an automated user interface (e.g., as identified generally by reference numeral 190) and a manual user interface (e.g., as identified generally by reference numeral 192). As explained in more detail below, automated user interface 190 may be the same or similar to conventional control panel interfaces on washing machine appliances. In this regard, automated user interface 190 generally permits user interaction to perform automated operating cycles of washing machine appliance 100. As explained above, certain users may wish to have more granular and detailed control of each operating function, subcycle, and/or operating cycle of washing machine appliance 100. Accordingly, aspects of the present subject matter are directed to a washing machine appliance with a manual user interface, such as manual user interface 192 to permit a manual mode of operation where a user of washing machine appliance 100 has more versatility and control in the operation of washing machine appliance 100. Although exemplary automated wash cycles and manual mode wash cycles are described herein, it should be appreciated that these exemplary modes of operation are only intended to facilitate discussion of aspects of the present subject matter. The specific operating modes, subcycles, and functions described herein are not intended to be limiting in any manner.

As used herein, references to automated wash cycles, automated algorithms, and the like are generally intended to refer to cycles initiated or actions performed by washing machine appliance 100 that require little to no user intervention in their operation. For example, if the user of washing machine appliance 100 wishes to throw a load of clothes into the wash chamber and hit start, the user may utilize automated user interface 190 for this purpose and washing machine appliance 100 may be programmed with a plurality of automated algorithms for implementing each cycle with no intervention from the user beyond pushing the start button.

By contrast, manual user interface 192 may include one or more buttons, such as a manual mode command button 194 for implementing a manual operating mode of washing machine appliance 100. In this regard, as will be described in more detail below, a user of washing machine appliance 100 may press manual mode command button 194 to cause controller 156 of washing machine appliance 100 to enter a manual operating mode where the user may regulate each subcycle and operating function, along with a selected subcycle parameters, to implement an operating cycle in accordance with the user's needs and desires. According to the illustrated embodiment, manual user interface 192 may have a manual mode display 196 and one or more controller parameter selection buttons 198 to simplify control and selection of subcycles and subcycle parameters. However, it should be appreciated that according to exemplary embodiments, the manual mode may be implemented with only manual mode command button 194 which may be used to cycle through and select the desired subcycles and subcycle parameters, as will be described in more detail below.

Although the controls illustrated in automated user interface 190 include rotary dials and press buttons and the controls illustrated in manual user interface 192 include a plurality of press buttons, it should be appreciated that any suitable number, type, and configuration of control inputs maybe used according to alternative embodiments of the present subject matter. Thus, according to alternative embodiments, automated user interface 190 and/or manual user interface 192 may include any suitable number and combination of touchscreen interfaces or a combination of capacitive touch buttons and digital display or static displays that may be selectively illuminated. According still other embodiments, these interfaces may include any suitable combination of toggle switches, push buttons, rotary dials, selective knobs, or other input mechanisms or selector switches.

While described in the context of a specific embodiment of vertical axis washing machine appliance 100, using the teachings disclosed herein it will be understood that vertical axis washing machine appliance 100 is provided by way of example only. Other washing machine appliances having different configurations, different appearances, and/or different features may also be utilized with the present subject matter as well, e.g., horizontal axis washing machine appliances. In addition, aspects of the present subject matter may be utilized in a combination washer/dryer appliance. Indeed, it should be appreciated that aspects of the present subject matter may further apply to other laundry appliances, such a dryer appliance.

Now that the construction of washing machine appliance 100 and the configuration of controller 156 according to exemplary embodiments have been presented, an exemplary method 200 of operating a washing machine appliance will be described. Although the discussion below refers to the exemplary method 200 of operating washing machine appliance 100, one skilled in the art will appreciate that the exemplary method 200 is applicable to the operation of a variety of other washing machine appliances, such as horizontal axis washing machine appliances, or other laundry appliances, such as a dryer appliance. In exemplary embodiments, the various method steps as disclosed herein may be performed by controller 156 or a separate, dedicated controller.

Referring now to FIG. 4, method 200 includes, at step 210, receiving a subcycle combination from a user interface device associated with a washing machine appliance. For example, this user interface device may be manual user interface 192, mobile phone 184, or any other suitable device permitting user interaction with washing machine appliance 100. As used herein, the term “subcycle combination” is generally intended to refer generally to the sequence of actions, functions, or subcycles that are performed during a single operating cycle of a washing machine appliance. The “operating cycle” is generally intended to refer to a complete operating cycle of washing machine appliance 100, e.g., including all subcycles. Thus, for example, an operating cycle begins immediately after a user puts a dirty load of clothes in wash chamber 110 and closes door 120. The operating cycle ends after all subcycles have been completed and the clothes are ready for removal from wash chamber 110. Thus, a common operating cycle of washing machine appliance 100 may include a prewash subcycle, a wash subcycle, a rinse subcycle, and a spin/drain subcycle.

According to exemplary embodiments, the subcycle combination received at step 210 includes one or more subcycles, the one or more subcycles including at least one of a fill subcycle, a prewash subcycle, a soak subcycle, a wash subcycle, a rinse subcycle, a drain subcycle, or a spin subcycle. Although exemplary subcycles are described herein, it should be appreciated that other subcycles and washing machine functions are possible for inclusion within the subcycle combination while remaining within the scope of the present subject matter. Notably, the inclusion of a subcycle combination enables a user to perform washing machine functions that were not possible with conventional washing machine appliances 100 (or not perform these subcycles when a user typically has no choice).

Notably, in order to provide more user versatility and control over the operating cycle of washing machine appliance 100, method 200 may include steps for facilitating user manipulation of specific parameters associated with each selected subcycle. Thus, according to an exemplary embodiment, step 220 may include obtaining subcycle parameters associated with each of the one or more subcycles in the subcycle combination. In general, the term “subcycle parameters” and the like is generally intended to refer to operating parameters specific to a certain subcycle of washing machine appliance. Exemplary subcycle parameters will be described below for subcycles described by the present disclosure. However, it should be appreciated that other subcycles and subcycle parameters are possible and within scope the present subject matter. Moreover, it should be appreciated that when a subcycle is selected for inclusion within the subcycle combination, the controller 156 may be programmed with a default set of subcycle parameters that a user may adjust using the user interface device (e.g., manual user interface 192 or mobile device 184). Thus, in the event a user does not adjust the subcycle parameters associated with a particular subcycle, controller 136 may implement the default or standard subcycle parameters.

According to exemplary embodiments, a fill subcycle may generally include the process of adding water or wash fluid to wash tub 108. In this regard, for example, water control valve 166 may be opened to provide hot water, cold water, or some combination of hot and cold water into wash tub 108. In addition, according to exemplary embodiments, the fill cycle may include adding one or more of detergent or wash additives into wash tub 108. According to exemplary embodiments, the subcycle parameters associated with the fill cycle may include a water fill amount or volume, a water fill level, a water temperature (e.g., in degrees Fahrenheit), etc. Thus, for example, if a user selects the fill subcycle, the user may further manipulate manual mode command button 194 or parameter selection buttons 198 to adjust the desired volume and temperature of water.

According to exemplary embodiments, a prewash subcycle may generally include any step of using water, detergent, and/or other wash additives to perform a preliminary washing procedure on a load of clothes prior to the main wash cycle. In this regard, for an extremely soiled load of clothes, the user may wish to select a prewash cycle for inclusion in the subcycle combination to improve the removal of excessive dirt and soil. According to exemplary embodiments, subcycle parameters associated with the prewash subcycle may include a water or wash fluid fill amount, a water temperature, an agitation time, and agitation intensity, a detergent amount, or any other suitable parameters for regulating a prewash cycle.

According to exemplary embodiments, a soak subcycle may generally include any step of saturating or submerging a load of clothes in water or wash fluid to help loosen soils, lighten stains, prepare a load of clothes for the main wash cycle, etc. Thus, for set in or stubborn stains or soils (e.g., such as grass or bloodstains), a user may wish soak the load of clothes to loosen the stains prior to the wash cycle. Thus, according to exemplary embodiments, the subcycle parameters that may be associated with a presoak subcycle may include a water level a soak time, and agitation time and intensity (if any), and overall soaking time, or any other suitable soaking parameters.

According to exemplary embodiments, a wash subcycle may generally refer to the primary washing process of a load of clothes. This wash cycle may occur after any prewash or soak subcycles and may include subcycle parameters such as the water fill amount, the water temperature, the agitation time and intensity, the detergent amount, etc. After a wash subcycle, it may be desirable to rinse the load of clothes. Accordingly, a rinse subcycle may generally refer to the process of draining dirty or soiled wash fluid in filling the wash tub with fresh water to facilitate removal of excess detergent, wash fluid, and soil from the load of clothes. Thus, according to exemplary embodiments, the rinse subcycle may include a water fill amount, a water temperature, and agitation time and/or intensity, etc. In addition, the rinse subcycle may include additional extra rinse cycles to remove any leftover wash fluid or detergent.

According to exemplary embodiments, a drain subcycle may generally refer to any cycle where wash fluid is removed from wash tub 108. Thus, according to an exemplary embodiment, a drain subcycle may include operating drain pump assembly 130 to evacuate wash fluid from wash tub 108. The drain subcycle may commonly be combined with a spin subcycle to extract additional water or wash fluid from the load of clothes to be drained. Subcycle parameters associated with the spin subcycle may include a spin time, a spin speed, etc. Although exemplary subcycles and subcycle parameters have been described herein, it should be appreciated that other subcycles and adjustable parameters are possible and within the scope of the present subject matter.

Step 230 may include receiving a start command from the user and step 240 may include initiating an operating cycle of the washing machine appliance in accordance with subcycle combination and the subcycle parameters. Thus, according to the illustrated embodiment, the start button may be one of input selectors 152 that may be depressed by the user after all subcycles have been selected and the subcycle parameters have been set. Specifically, according to the illustrated embodiment, washing machine appliance 100 may perform each selected subcycle within the subcycle combination in the prescribed order and in accordance with the selected parameters by the user. Notably, this level of versatility and manipulation of all operating parameters of washing machine appliance 100 are not presently available or known within a washing machine market.

Referring now briefly to FIG. 5, an exemplary method 300 of implementing a manual mode of operation will be described according to exemplary embodiments the present subject matter. For example, method 300 may be implemented using a manual user interface 192 to operate washing machine appliance 100, e.g., by repeatedly pressing manual mode command button 194 and/or parameter selection buttons 198 until the desired subcycle combination and subcycle parameters are selected. Specifically, method 300 may include pressing the manual mode command button 194 several times as indicated repeatedly by steps 302. Each press of manual mode command button 194 may cycle through the various combinations of potential subcycle combinations, such as fill only 304, fill and wash only 306, fill and soak only 308, fill, wash, and drain only 310, fill, wash, drain, and rinse only 312, drain only 314, and drain and spin only 316. Notably, once the desired subcycle combination is selected, a user may select the subcycle parameters associated with each subcycle in that subcycle combination, e.g., at step 304 through 316. The user may then press the start button at step 320 and the washing machine may implement the selected subcycle combination along with subcycle parameters at steps 322.

As explained above, manipulation of the subcycle combinations and associated subcycle parameters may be input using manual user interface 192 e.g., via control panel 150. Notably, according to alternative embodiments, a remote device, such as mobile phone 184 may be used to select subcycle combinations and subcycle parameters. Specifically, referring now to FIG. 6, a method 400 of implementing a manual mode for a washing machine appliance will be described. Specifically, method 400 may include using a remote device such as mobile phone 184 to make such selections. In this regard, mobile phone 184 may be programmed with a software application that provides interactive prompts and control of various subcycles and associated parameters.

In this regard, step 402 may include selecting the manual mode. For example, this may be done directly through the software application on the mobile phone 184 or may be initiated on the mobile phone by pressing manual mode command button 194. A user may then click on or select the desired subcycles to be included in the subcycle combination (e.g., as identified generally by reference numeral 404). If a particular subcycle is selected for inclusion in the subcycle combination, the software application may prompt the user to enter the desired subcycle parameters as identified generally by reference numeral 406. In this regard, for example, if a prewash subcycle is selected, the user may be queried to determine the desired fill amount, temperature, agitation time and intensity, detergent amount, etc. After the user has populated all the desired subcycles for inclusion within the subcycle combination and the desired subcycle parameters for each selected subcycle, the user may press a start button at 410. The start button may be programmed into the software application on the mobile phone 184 or the user may press the start button on control panel 150. At this point, step 412 includes implementing the manual mode of operation by performing operating cycle that includes all the subcycles in the subcycle combination in accordance with their selected subcycle parameters.

FIGS. 4 through 6 depict steps performed in a particular order for purposes of illustration and discussion. Those of ordinary skill in the art, using the disclosures provided herein, will understand that the steps of any of the methods discussed herein can be adapted, rearranged, expanded, omitted, or modified in various ways without deviating from the scope of the present disclosure. Moreover, although aspects of methods 200, 300, and 400 are explained using washing machine appliance 100 as an example, it should be appreciated that these methods may be applied to the operation of any suitable laundry appliance, such as another washing machine appliance.

Aspects of the present subject matter as described herein provide improved operating software or appliance cycle algorithms that may be manually regulated by a user through a user interface device, such as the appliance control panel and/or an enabled software application on the user's remote device (e.g., a mobile phone). Notably, interaction with this user interface device may facilitate full user control of the washing machine appliance to initiate the performance of very specific machine actions. This can provide several advantages, as nearly all conventional washing machines include electronic controls that provide little versatility and do not allow users to control specific elements, function, or subcycles of the washing machine operation, thereby causing frustration in users who have very specific washing needs.

For example, for persons who dye their own fabrics and use the washing machine for that purpose, a specific series of steps at specific times is critical for successful results. As another example, a user may have a textile item requiring special care which needs only specific cycle steps to successfully treat it, and where inclusion of the other cycle steps offered in standard cycles may damage or provide less optimal results. Appliance manufacturers cannot typically anticipate every consumer need or tailor a specific cycle to meet such exacting consumer need. However, aspects of the present subject matter provide a manual mode where a user may independently and selectively manipulate many different washing machine parameters and cycles in a manner that meets their specific needs.

Specifically, according to an exemplary embodiment, the user interface device may include the control panel of the appliance. This control panel may include a manual mode button or manual input button that is independent and distinct from the conventional automatic cycle control buttons. The user may press this manual mode button to slew through individual and combined machine functions or subcycles to allow the specific functions or group of functions desired. The user may use the manual mode button to activate or deactivate each of a variety of specific functions or subcycles. The control panel could then prompt the user to input subcycle parameters associate with each of the selected functions. For example, if the “fill subcycle” is selected, the control panel could prompt the user to toggle through various options for the fill level or volume and the water temperature, e.g., through repeatedly pressing the manual mode button. According to still other embodiments, the control panel may include a separate button for each of the subcycles or machine functions so that a user may select/deselect individual functions and may specify detailed operating parameters associated with each function.

According to still other embodiments, the user interface device could be a connected software application on a remote device, such as a user's mobile phone. When manual mode is activated through the software application, the phone screen could display all possible functions or subcycles, could include a visual depiction of each washer function, etc. Each of those functions would be selectable and, upon selecting a function, modifiers of that function would be displayed for selection to customize the functions operation beyond the provided defaults. Once each of the desired functions are selected and customized, the user could select Start and the software application would communicate the desired functions to the washing machine for execution.

The above-described manual mode of operation would be very beneficial in many instances, only some of which have been described herein. It could allow for simplification of the user interface by combining many functions and combinations of functions into a single button. The user could slew through individual and combinations of functions as shown by status indicator lights. The manual mode feature could also be very useful in the cases where machine diagnostics were needed. For example, the manual mode could provide an easy way for service call takers or maintenance technicians to ask consumers to try different functions of their washing machine appliance to possibly help prevent a costly service visit, and it would be very helpful and time saving for service technicians and installers. In addition, the manual mode could provide improved machine versatility and ultimate control and customization of the washing machine for those users who need it for specific laundry tasks.

This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
