Laundry treating appliances, such as washing machines, refreshers, and non-aqueous systems, can have a configuration based on a rotating container that at least partially defines a treating chamber in which laundry items are placed for treating. The laundry treating appliance can have a controller that implements a number of user-selectable, pre-programmed cycles of operation. Hot water, cold water, or a mixture thereof along with various treating chemistries, or detergents, can be supplied to the treating chamber in accordance with the cycle of operation. In vertical or horizontal axis washing machines a detergent dispenser can be in the form of a drawer fluidly coupled to the treating chamber to receive a volume of detergent to treat the laundry items according to the cycle of operation. The drawer usually includes containers for treating chemistries such as detergent or fabric softener and can supply the treating chemistries to the treating chamber via a conduit.
Laundry treating appliances typically operate to treat laundry items by placing the laundry items in contact with cleaning fluid such as soapy water, and providing relative motion between the laundry items and the fluid. Commonly, a fabric mover, such as an agitator, provides mechanical energy to a load of laundry items immersed in the cleaning fluid by agitating the laundry load in a manner that both jostles the laundry items in the fluid and circulates the fluid through the laundry items. A laundry treating appliance for home use can perform a select programmed series of operations on fabric placed in a basket or drum located within the interior of the machine. However, it can occur that none of a selection of preprogrammed wash cycles is thought by the washing machine user to be sufficient to fully remove certain stains on the fabric being laundered. The user can choose to address such stains manually before adding the stained laundry items to the laundry load.
In one aspect, the present disclosure relates to a laundry treating appliance including a chassis defining an interior, a treating chamber located within the interior, a drawer slidably received within the interior and containing a dispenser having at least one treating chemistry reservoir fluidly coupled to the treating chamber, and a treating tool having an internal treating chemistry reservoir and positioned within the dispenser to fluidly couple the internal treating chemistry reservoir with the treating chamber.
In another aspect, the present disclosure relates to a laundry treating appliance including a chassis defining an interior, a treating chamber located within the interior and having a fluid inlet, a removable treating tool having an internal treating chemistry reservoir with a fluid outlet, and a fluid coupling between the fluid outlet of the internal treating chemistry reservoir and the fluid inlet of the treating chamber.
In the drawings:
Washing machines are typically categorized as either a vertical axis washing machine or a horizontal axis washing machine. As used herein, the term “horizontal axis” washing machine refers to a washing machine having a rotatable drum that rotates about a generally horizontal axis relative to a surface that supports the washing machine. The drum can rotate about the axis inclined relative to the horizontal axis, with fifteen degrees of inclination being one example of the inclination. Similar to the horizontal axis washing machine, the term “vertical axis” washing machine refers to a washing machine having a rotatable drum that rotates about a generally vertical axis relative to a surface that supports the washing machine. However, the rotational axis need not be perfectly vertical to the surface. The drum can rotate about an axis inclined relative to the vertical axis, with fifteen degrees of inclination being one example of the inclination.
In another aspect, the terms vertical axis and horizontal axis are often used as shorthand terms for the manner in which the appliance imparts mechanical energy to the laundry, even when the relevant rotational axis is not absolutely vertical or horizontal. As used herein, the “vertical axis” washing machine refers to a washing machine having a rotatable drum, perforate or imperforate, that holds fabric items and a clothes mover, such as an agitator, impeller, nutator, and the like within the drum. The clothes mover moves within the drum to impart mechanical energy directly to the clothes or indirectly through wash liquid in the drum. The clothes mover may typically be moved in a reciprocating rotational movement. In some vertical axis washing machines, the drum rotates about a vertical axis generally perpendicular to a surface that supports the washing machine. However, the rotational axis need not be vertical. The drum may rotate about an axis inclined relative to the vertical axis.
As used herein, the “horizontal axis” washing machine refers to a washing machine having a rotatable drum, perforated or imperforate, that holds laundry items and washes the laundry items. In some horizontal axis washing machines, the drum rotates about a horizontal axis generally parallel to a surface that supports the washing machine. However, the rotational axis need not be horizontal. The drum can rotate about an axis inclined or declined relative to the horizontal axis. In horizontal axis washing machines, the clothes are lifted by the rotating drum and then fall in response to gravity to form a tumbling action. Mechanical energy is imparted to the clothes by the tumbling action formed by the repeated lifting and dropping of the clothes. Vertical axis and horizontal axis machines are best differentiated by the manner in which they impart mechanical energy to the fabric articles.
Regardless of the axis of rotation, a washing machine can be top-loading or front-loading. In a top-loading washing machine, laundry items are placed into the drum through an access opening in the top of a cabinet, while in a front-loading washing machine laundry items are placed into the drum through an access opening in the front of a cabinet. If a washing machine is a top-loading horizontal axis washing machine or a front-loading vertical axis washing machine, an additional access opening is located on the drum.
The laundry treating appliance of
The laundry holding system includes a tub 14 supported within the cabinet 12 by a suitable suspension system and a drum 16 provided within the tub 14. The drum 16 defines at least a portion a laundry treating chamber 18 for receiving a laundry load for treatment. The drum 16 is configured to receive a laundry load comprising articles for treatment, including, but not limited to, a hat, a scarf, a glove, a sweater, a blouse, a shirt, a pair of shorts, a dress, a sock, and a pair of pants, a shoe, an undergarment, and a jacket. The drum 16 can include a plurality of perforations 20 such that liquid can flow between the tub 14 and the drum 16 through the perforations 20. A plurality of baffles 22 can be disposed on an inner surface of the drum 16 to lift the laundry load received in the treating chamber 18 while the drum 16 rotates. It can also be within the scope of the present disclosure for the laundry holding system to comprise only one receptacle with the receptacle defining the laundry treating chamber for receiving the load to be treated.
The laundry treating chamber 18 can have an opening or open face that can be selectively closed by a cover, such as a door 24. More specifically, the door 24 can be movably mounted to the cabinet 12 to selectively close both the tub 14 and the drum 16. A bellows 26 can couple an open face of the tub 14 with the cabinet 12, with the door 24 sealing against the bellows 26 when the door 24 closes the tub 14.
The washing machine 10 can further include a suspension system 28 for dynamically suspending the laundry holding system within the structural support system.
The washing machine 10 can further include a liquid supply system for supplying water to the washing machine 10 for use in treating laundry during a cycle of operation. The liquid supply system can include a source of water, such as a household water supply 40, which can include separate valves 42 and 44 for controlling the flow of hot and cold water, respectively. Water can be supplied through an inlet conduit 46 directly to the tub 14 by controlling first and second diverter mechanisms 48 and 50, respectively. The diverter mechanisms 48, 50 can be a diverter valve having two outlets such that the diverter mechanisms 48, 50 can selectively direct a flow of liquid to one or both of two flow paths. Water from the household water supply 40 can flow through the inlet conduit 46 to the first diverter mechanism 48 which can direct the flow of liquid to a supply conduit 52. The second diverter mechanism 50 on the supply conduit 52 can direct the flow of liquid to a tub outlet conduit 54 which can be provided with a spray nozzle 56 configured to spray the flow of liquid into the tub 14. In this manner, water from the household water supply 40 can be supplied directly to the tub 14. While the valves 42, 44 and the conduit 46 are illustrated exteriorly of the cabinet 12, it will be understood that these components can be internal to the cabinet 12.
The washing machine 10 can also be provided with a dispensing system for dispensing treating chemistry to the treating chamber 18 for use in treating the laundry according to a cycle of operation. The dispensing system can include a treating chemistry dispenser 60 which can be a single dose dispenser, a bulk dispenser, or an integrated single dose and bulk dispenser and is fluidly coupled to the treating chamber 18. The treating chemistry dispenser 60 can be configured to dispense a treating chemistry directly to the tub 14 or mixed with water from the liquid supply system through a dispensing outlet conduit 64. The dispensing outlet conduit 64 can include a dispensing nozzle 66 configured to dispense the treating chemistry into the tub 14 in a desired pattern and under a desired amount of pressure. For example, the dispensing nozzle 66 can be configured to dispense a flow or stream of treating chemistry into the tub 14 by gravity, i.e. a non-pressurized stream. Water can be supplied to the treating chemistry dispenser 60 from the supply conduit 52 by directing the diverter mechanism 50 to direct the flow of water to a dispensing supply conduit 68.
The treating chemistry dispenser 60 can include multiple chambers or reservoirs fluidly coupled to the treating chamber 18 for receiving doses of different treating chemistries. The treating chemistry dispenser 60 can be implemented as a dispensing drawer that is slidably received within the cabinet 12, or within a separate dispenser housing which can be provided in the cabinet 12. The treating chemistry dispenser 60 can be moveable between a fill position, where the treating chemistry dispenser 60 is exterior to the cabinet 12 and can be filled with treating chemistry, and a dispense position, where the treating chemistry dispenser 60 is interior of the cabinet 12.
Non-limiting examples of treating chemistries that can be dispensed by the dispensing system during a cycle of operation include one or more of the following: water, enzymes, fragrances, stiffness/sizing agents, wrinkle releasers/reducers, softeners, antistatic or electrostatic agents, stain repellants, water repellants, energy reduction/extraction aids, antibacterial agents, medicinal agents, vitamins, moisturizers, shrinkage inhibitors, and color fidelity agents, and combinations thereof.
The washing machine 10 can also include a recirculation and drain system for recirculating liquid within the laundry holding system and draining liquid from the washing machine 10. Liquid supplied to the tub 14 through tub outlet conduit 54 and/or the conduit 64 typically enters a space between the tub 14 and the drum 16 and can flow by gravity to a sump 70 formed in part by a lower portion of the tub 14. The sump 70 can also be formed by a sump conduit 72 that can fluidly couple the lower portion of the tub 14 to a pump 74. The pump 74 can direct liquid to a drain conduit 76, which can drain the liquid from the washing machine 10, or to a recirculation conduit 78, which can terminate at a recirculation inlet 80. The recirculation inlet 80 can direct the liquid from the recirculation conduit 78 into the drum 16. The recirculation inlet 80 can introduce the liquid into the drum 16 in any suitable manner, such as by spraying, dripping, or providing a steady flow of liquid. In this manner, liquid provided to the tub 14, with or without treating chemistry, can be recirculated into the treating chamber 18 for treating the laundry within.
The liquid supply and/or recirculation and drain system can be provided with a heating system which can include one or more devices for heating laundry and/or liquid supplied to the tub 14, such as a steam generator 82 and/or a sump heater 84. Liquid from the household water supply 40 can be provided to the steam generator 82 through the inlet conduit 46 by controlling the first diverter mechanism 48 to direct the flow of liquid to a steam supply conduit 86. Steam generated by the steam generator 82 can be supplied to the tub 14 through a steam outlet conduit 87. The steam generator 82 can be any suitable type of steam generator such as a flow through steam generator or a tank-type steam generator. Alternatively, the sump heater 84 can be used to generate steam in place of or in addition to the steam generator 82. In addition or alternatively to generating steam, the steam generator 82 and/or sump heater 84 can be used to heat the laundry and/or liquid within the tub 14 as part of a cycle of operation.
It is noted that the illustrated suspension system, liquid supply system, recirculation and drain system, and dispensing system are shown for exemplary purposes only and are not limited to the systems shown in the drawings and described above. For example, the liquid supply, dispensing, and recirculation and pump systems can differ from the configuration shown in
The washing machine 10 also includes a drive system for rotating the drum 16 within the tub 14. The drive system can include a motor 88 for rotationally driving the drum 16. The motor 88 can be directly coupled with the drum 16 through a drive shaft 90 to rotate the drum 16 about a rotational axis during a cycle of operation. The motor 88 can be a brushless permanent magnet (BPM) motor having a stator 92 and a rotor 94. Alternately, the motor 88 can be coupled with the drum 16 through a belt and a drive shaft to rotate the drum 16, as is known in the art. Other motors, such as an induction motor or a permanent split capacitor (PSC) motor, can also be used. The motor 88 can rotationally drive the drum 16 including that the motor 88 can rotate the drum 16 at various speeds in either rotational direction.
The control system can control the operation of the washing machine 10 to implement one or more cycles of operation. The control system can include a controller 96 located within the cabinet 12 and a user interface 98 that can be operably coupled with the controller 96. The user interface 98 can provide an input and output function for the controller. The user interface 98 can include one or more knobs, dials, switches, displays, touchscreens, and the like for communicating with the user, such as to receive input and provide output. For example, the displays can include any suitable communication technology including that of a liquid crystal display (LCD), a light-emitting diode (LED) array, or any suitable display that can convey a message to the user. The user can enter different types of information including, without limitation, cycle selection, and cycle parameters, such as cycle options. Other communications paths and methods can also be included in the washing machine 10 and can allow the controller 96 to communicate with the user in a variety of ways. For example, the controller 96 can be configured to send a text message to the user, send an electronic mail to the user, or provide audio information to the user either through the washing machine 10 or utilizing another device such as a mobile phone.
The controller 96 can include the machine controller and any additional controllers provided for controlling any of the components of the washing machine 10. For example, the controller 96 can include the machine controller and a motor controller. Many known types of controllers can be used for the controller 96. The specific type of controller is not germane to the present disclosure. It is contemplated that the controller can be a microprocessor-based controller that implements control software and sends/receives one or more electrical signals to/from each of the various working components to effect the control software. As an example, proportional control (P), proportional integral control (PI), and proportional derivative control (PD), or a combination thereof, a proportional integral derivative control (PID control), can be used to control the various components.
As illustrated in
The controller 96 can be operably coupled with one or more components of the washing machine 10 for communicating with and controlling the operation of the component to complete a cycle of operation. For example, the controller 96 can be operably coupled with the motor 88, the pump 74, the treating chemistry dispenser 60, the steam generator 82 and the sump heater 84 to control the operation of these and other components to implement one or more of the cycles of operation.
The controller 96 can also be coupled with one or more sensors 104 provided in one or more of the systems of the washing machine 10 to receive input from the sensors 104, which are known in the art and not shown for simplicity. Non-limiting examples of sensors 104 that can be communicably coupled with the controller 96 include: a treating chamber temperature sensor, a moisture sensor, a weight sensor, a chemical sensor, a position sensor, an imbalance sensor, a load size sensor, and a motor torque sensor, which can be used to determine a variety of system and laundry characteristics, such as laundry load inertia or mass.
The tool recess 132 is defined by side walls 144 and a bottom wall 146. The bottom wall 146 can define at least one drain opening 148 that fluidly couples the tool recess 132 and the tool docking station 126 to the treating chamber 18. Further, the tool recess 132 and tool docking station 126 can be fluidly coupled to the treating chamber 18 via the at least one treating chemistry reservoir 120, 122. In the aspect illustrated in
The tool docking station 126 can further and optionally comprise a collecting portion 154 that underlies the at least one drain opening 148. The collecting portion 154 can be fluidly coupled to the at least one treating chemistry reservoir 120, 122 via a drain conduit 156. Thus, in any additional contemplated positions or locations (
In one non-limiting example, the tool body recess 162 is at least partially located in the handle 150 and shaped to receive the internal treating chemistry reservoir 160. The internal treating chemistry reservoir 160 can be configured to receive a pretreating liquid or a chemistry pod. The internal treating chemistry reservoir 160 can be filled with pretreating liquid, for example, by opening the treating tool 134 and pouring liquid directly into the internal treating chemistry reservoir 160. In these aspects, the treating tool 134 can have a dispenser (not shown) that is operated by pushing on a compressible element 164 that activates a valve or conveys pressure to a liquid pump fluidly coupled to at least one of the internal treating chemistry reservoir 160 or the drain opening 148 to pump and to dispense the liquid in the internal treating chemistry reservoir 160 through the drain opening 148. When the treating tool 134 is docked within the tool docking station 126, this coupling further results in the contents of the internal treating chemistry reservoir 160 being pumped to the treating chamber 18. While the compressible element 164 is shown on the handle 150, other types and/or arrangements of dispensers can alternatively be used and incorporated into the treating tool 134.
The internal treating chemistry reservoir 160 can include a reservoir outlet 166. The tool body 158 can further comprise at least one tool outlet 168, which is fluidly coupled with the reservoir outlet 166. The tool outlet 168 can be adjacent or coextensive with the set of bristles 152 to allow the pretreating liquid to be released to the area of the set of bristles 152 from the internal treating chemistry reservoir 160. When the treating tool 134 is docked within the tool docking station 126, the internal treating chemistry reservoir 160 can be thought of as being fluidly coupled with the treating chamber 18 via the treating tool 134, the tool docking station 126, and the treating chemistry dispenser 60. Further, the tool outlet 168 can be understood to fluidly couple the internal treating chemistry reservoir 160 with the tool recess 132, and further to the treating chamber 18 via the drain openings 148. The drain opening 148 can be thought of as comprising a first fluid coupling, while the treating tool 134 can be thought of as comprising a second fluid coupling, wherein the second fluid coupling fluidly mates with the first fluid coupling when the treating tool 134 is docked and docked within the tool docking station 126 to fluidly couple the internal treating chemistry reservoir 160 to the drain opening 148. As disclosed previously, a water supply line, such as the dispensing supply conduit 68, can be provided and configured to supply water to the tool docking station 126, and to the tool recess 132, which can assist in flushing the treating chemistry from the treating tool 134 through the drain opening 148, and to the treating chamber 18.
It is noted that the treating tool 134 illustrated in
While the tool docking station 126 has been illustrated herein as being provided within the drawer cover 124,

The fabric holding system of the illustrated exemplary washing machine 210 can include a rotatable basket 230 having an open top 213 that can be disposed within the interior of the cabinet 214 and may define a treating chamber 232 for receiving laundry items for treatment. The open top can be aligned with the access opening 215. A tub 234 can also be positioned within the cabinet 214 and can define an interior within which the basket 230 can be positioned. The tub 234 can have a generally cylindrical side or tub peripheral wall 212 closed at its bottom end by a base 216 that can at least partially define a sump 260.
The basket 230 can have a generally peripheral side wall 218, which is illustrated as a cylindrical side wall, closed at the basket end by a basket base 220 to at least partially define the treating chamber 232. The basket 230 can be rotatably mounted within the tub 234 for rotation about a vertical basket axis of rotation and can include a plurality of perforations, such that liquid may flow between the tub 234 and the rotatable basket 230 through the perforations. While the illustrated washing machine 210 includes both the tub 234 and the basket 230, with the basket 230 defining the treating chamber 232, it is within the scope of the present disclosure for the laundry treating appliance to include only one receptacle, with the receptacle defining the laundry treatment chamber for receiving the load to be treated.
A shroud 229 is provided at the top of the cabinet 214 and can define the access opening 215. The shroud 229 can curve downwards toward the treating chamber 232 to direct laundry items into the basket 230. The shroud 229 can overlie a portion of the basket 230 such that the laundry items do not fall between the basket 230 and the tub 234. A selectively openable lid 228 can provide access into the laundry treating chamber 232 through the access opening 215 of the basket 230.
A laundry mover 238 may be rotatably mounted within the basket 230 to impart mechanical agitation to a load of laundry placed in the basket 230. The laundry mover 238 can be oscillated or rotated about its vertical axis of rotation during a cycle of operation in order to produce load motion effective to wash the load contained within the treating chamber 232. Other exemplary types of laundry movers include, but are not limited to, an agitator, a wobble plate, and a hybrid impeller/agitator.
A liquid supply system can be provided to provide liquid, such as water or a combination of water and one or more wash aids, such as detergent, into the treating chamber 232. The liquid supply system can include a water supply 244 configured to supply hot or cold water. The water supply 244 can include a hot water inlet 245 and a cold water inlet 246. A valve assembly can include a hot water valve 248, a cold water valve 250, and a diverter valve 255, and various conduits 252, 256, 258 for selectively distributing the water supply 244 from the hot water and cold water inlets 245, 246. The valves 248, 250 are selectively openable to provide water, such as from a household water supply (not shown) to the conduit 252. The valves 248, 250 can be opened individually or together to provide a mix of hot and cold water at a selected temperature. While the valves 248, 250 and conduit 252 are illustrated exteriorly of the cabinet 214, it may be understood that these components can be internal to the cabinet 214.
A dispensing system 253 can be provided for dispensing treating chemistry to the basket 230, either directly or mixed with water from the water supply 244. The dispensing system 253 can include a dispenser 254, which can be a single use dispenser, a bulk dispenser, or a combination of a single use and bulk dispenser in non-limiting examples. As illustrated, the dispenser 254 can be fluidly coupled with the conduit 252 through a diverter valve 255 and a first water conduit 256. The dispensing system 253 can include means for supplying or mixing detergent to or with water from the first water conduit 256. Alternatively, water from the first water conduit 256 can also be supplied to the tub 234 through the detergent dispenser 254 without the addition of a detergent. A second water conduit, illustrated as the water inlet 258, can also be fluidly coupled with the conduit 252 through the diverter valve 255 such that water can be supplied directly to the treating chamber through the open top of the basket 230.
Non-limiting examples of treating chemistries that can be dispensed by the dispensing system during a cycle of operation include one or more of the following: water, detergents, surfactants, enzymes, fragrances, stiffness/sizing agents, wrinkle releasers/reducers, softeners, antistatic or electrostatic agents, stain repellants, water repellants, energy reduction/extraction aids, antibacterial agents, medicinal agents, vitamins, moisturizers, shrinkage inhibitors, and color fidelity agents, and combinations thereof. The treating chemistries can be in the form of a liquid, powder, or any other suitable phase or state of matter.
Additionally, the liquid supply system and dispensing system 253 can differ from the configuration shown, such as by inclusion of other valves, conduits, wash aid dispensers, heaters, sensors, such as water level sensors and temperature sensors, and the like, to control the flow of treating liquid through the washing machine 210 and for the introduction of more than one type of detergent/wash aid.
The washing machine 210 can further include a controller 270 coupled with various working components of the washing machine 210 to control the operation of the working components and to implement one or more treating cycles of operation. A user interface 226 can be operably coupled with the controller 270. The user interface 226 can include one or more knobs, dials, switches, displays, touch screens and the like for communicating with the user, such as to receive input and provide output. The user can enter different types of information including, without limitation, cycle selection and cycle parameters, such as cycle options.
The controller 270 can be operably coupled with one or more components of the washing machine 210 for communicating with and/or controlling the operation of the components to complete a cycle of operation. For example, the controller 270 can be coupled with the hot water valve 248, the cold water valve 250, the diverter valve 255, and the dispenser 254 for controlling the temperature and flow rate of treating liquid into the treating chamber 232, and the user interface 226 for receiving user selected inputs and communicating information to the user.
Looking now at the dispensing system 253 in greater detail, reference is made to
The faucet 284 can be provided on the drawer 280. The faucet 284 can underlie the shroud 229 when the drawer 280 is in the closed, first position. The faucet 284 has an outlet 286 provided in the front panel 268 of the dispenser 254. The outlet 286 can be formed as an aperture in the drawer 280 or the shroud 229. A pre-treatment water flow, or supply of water 300, can be provided from the faucet 284 at the outlet 286, and dispensed to the treating chamber 232 through the access opening 215. In particular, the supply of water 300 can be provided from the dispenser 254 at the faucet 284. When the drawer 280 is in the first position the supply of water 300 can be directed in a stream flowing out of the outlet 286 in the faucet 284 and toward the treating chamber 232 in a downward direction.
An actuator 290 can operably couple to the dispenser 254 to control the supply of water 300 from the faucet 284. A user can operate the actuator 290 to utilize the faucet 284 for pre-treatment of laundry items. In this illustrative example, the actuator 290 is in the form of a switch 292. However, the actuator 290 can be any suitable actuable element, such as a switch, button, dial, or knob. The actuator 290 can be provided on the shroud 229 or the dispenser 254, such that the actuator 290 is accessible through the access opening 215 while the lid 228 is in the opened position. While the actuator 290 is shown as being located on the shroud 229, the actuator 290 can be located on any other suitable location accessible by a user, such as on the cabinet 214, drawer 280, or user interface 226. The actuator 290 can be a mechanical actuator wherein the supply of water 300 is controlled by way of a mechanical operation, or the actuator 290 can be an electrical actuator wherein the supply of water 300 is controlled by way of an electric signal or current. Alternatively, it is contemplated that any suitable operable control mechanism be used to control the supply of water 300.
When the lid 228 is open, the faucet 284 is accessible and enables a user utilize the faucet 284 to dispense water onto fabric items for pre-treatment. After the lid 228 is closed and the washing machine 210 begins an automatic cycle of operation, the faucet 284 should not further dispense water. Instead, the treating chemistry containers 281, 283, 285 can dispense treating chemistry for use during the automatic cycle of operation.
In use, the faucet 284 can be used to treat a laundry item prior to the washing machine 210 running an automatic cycle of operation. In a first example, a laundry item can be placed underneath the faucet 284 in the trajectory of the supply of water 300 flowing out of the outlet 286. The user can actuate the actuator 290 to start the supply of water 300 from the faucet 284. The laundry item can be at least partially saturated with the supply of water 300. The wet laundry treating item can be treated by the user, such as rubbing or brushing a stain using a treating tool 334 (
A set of one or more containers, shown here as a first container 281, a second container 283, and a third container 285, can be carried by the drawer 280. The containers 281, 283, and 285 can hold differing types of liquids or powders, such as water or treating chemistry including detergent, fabric softener, or stain repellent. It is also contemplated that at least two of the containers 281, 283, and 285 are different in volume. Furthermore, the particular containers 281, 283, and 285 can be tailored to particular treating chemistries, and can include indicia or labelling to identify the particular intended treating chemistries.
At least one of the containers 281, 283, and 285 can be adapted to facilitate water flow for the faucet 284. In this example, the second container 283 at least partially defines the faucet 284 and can include the outlet 286. As such, the drawer 280 including the second container 283 can at least partially form the faucet 284 as described herein. The second container 283 includes a bottom 287 and sides 289 such that a volume of water or treating chemistry is constrained within the second container 283. The outlet 286 can be provided in the bottom 287 or the sides 289 of the second container 283, providing egress for water or treating chemistry within the second container 283. This enables the pre-treatment water faucet functionality to be provided within the structure of the dispenser drawer 280, resulting in a simple, low-complexity, and low-cost implementation.
The second container 283 can further define a tool recess 332 and include a tool docking station 326 (
Turning to
The valve 302 can be supplied with both the hot water inlet 245 and the cold water inlet 246 and can control the temperature based upon instruction from the actuator 290. The actuator 290 can allow a user to choose the temperature of water supplied to the second container 283 by operating valves associated with the hot water inlet 245 or the cold water inlet 246 from the valve 302. Alternatively, water temperature can be controlled at the user interface.
Upon actuation of the actuator 290, the valve 302 can provide the supply of water via the water supply 244 to the water line 298 through the valve 302. The supply of water via the water supply 244 is passed to the second container 283 and can then exit the faucet 284 at the outlet 286. Thus, the supply of water can be used to saturate a laundry item with the supply of water 300, while still containing spill-over water within the treating chamber 232.
The tool docking station 326 can be provided within the tool recess 332 defined by the second container 283. The treating tool 334 can couple with the tool docking station 326 in any suitable manner, such as by coupling only along a single edge of the treating tool 334 by a snap fit arrangement, a slidable arrangement, or a magnetic coupling between the treating tool 334 and the tool docking station 326. The treating tool 334 can dock with the tool docking station 326 such that the treating tool 334 rests on the bottom 287 or just above the bottom 287 of the second container 283. This allows water that is passing through the second container 283 to the outlet 286 to pass the treating tool 334 and to rinse the treating tool 334 and the set of bristles, such that the outlet 286 acts as a drain for the tool recess 332.
The faucet 284 can dispense water alone, or water mixed with treating chemistry. For example, the supply of water provided by the faucet 284 can include a stain treating chemistry to pre-treat laundry items prior to washing. A user can also or alternatively fill the second container 283 with a pre-treating chemistry or other treating chemistry prior to actuation of the actuator 290, such as by dispensing a treating chemistry from the treating tool 334 as described previously. At actuation of the actuator 290 the supply of water passes through the second container 283 to mix with the treating chemistry to form a mixed supply. The mixed supply exists the outlet 286 and is supplied from the faucet 284 to the treating chamber for pre-treatment of laundry. Alternately, if the user does not fill the second container 283 with a treating chemistry, the supply of water does not mix with treating chemistry.
In use, the user can open the drawer 280 and fill the second container 283 with a volume of treating chemistry, such as a stain-treatment, by dispensing such a volume of treating chemistry from the treating tool 334, or simply by using the treating tool 334 to stain treat a laundry item and allowing the residual treating chemistry retained on the treating tool 334 after use to collect within the second container 283, which the treating tool 334 overlies when docked with the tool docking station 326. The user can close drawer 280 with the treating chemistry retained in the second container 283. The user can then actuate the actuator 290 to provide the supply of water 300 to the second container 283 to mix with the treating chemistry. The mixture of water and treating chemistry is dispensed from the faucet 284 where a user can use the mixture of water and treating chemistry to at least partially saturate a laundry item. The user can then treat the laundry item, such as by rubbing the laundry item with the user's hands or by using the treating tool 334, or another brush, sponge, or other suitable treatment utensil. Alternatively, the user could simply wet the laundry item with the mixture of water and chemistry prior to running a cycle of operation, without treating the laundry item, to provide for increased treatment to desired laundry items or portions of laundry items.
The dispenser 254 obviates the need for an external sink or space for pre-washing or pre-treating laundry. Having the faucet 284 integrated into the dispenser 254 can enable a user to pre-treat laundry items prior to running a cycle of operation, while containing any liquid or treating chemistry within the treating chamber of the washing machine. The dispenser 254 also minimizes or eliminates additional space otherwise required to route the supply of water 300 as the supply of water 300 can already be supplied to the dispenser 254 for providing treating chemistry to the treating chamber.
The aspects of the present disclosure provide a treating tool that can be conveniently docked in a tool docking station for ease of use by a user. By incorporating the tool docking station into an already existing treating chemistry dispenser, no additional space is taken up, but the user can still be provided with easy access to the treating tool for pre-treatment of laundry items. Furthermore, by incorporating the tool docking station within the treating chemistry dispenser, the tool docking station can be fluidly coupled to the treating chamber and have water supplied to the tool docking station to rinse residual or dispensed treating chemistry away from the tool docking station and the treating tool. By incorporating a treating chemistry reservoir within the treating tool, performance of pre-treatment can be improved even further and can provide a greater degree of user control over a pre-treatment process or the ability to add a pre-treating agent to the treating chamber simply by dispensing from the treating tool.
To the extent not already described, the different features and structures of the various aspects can be used in combination with each other as desired. That one feature may not be illustrated in all of the aspects of the disclosure is not meant to be construed that it cannot be, but is done for brevity of description. Thus, the various features of the different aspects can be mixed and matched as desired to form new aspects, whether or not the new aspects are expressly described. All combinations or permutations of features described herein are covered by this disclosure.
While the present disclosure has been specifically described in connection with certain specific aspects thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the forgoing disclosure and drawings without departing from the spirit of the present disclosure which is defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the aspects of the present disclosure are not to be considered as limiting, unless expressly stated otherwise.
This application is a continuation application of U.S. patent application Ser. No. 16/587,913, filed Sep. 30, 2019, now U.S. Pat.
