Laundry treating appliances, such as clothes washers, clothes dryers, refreshers, and non-aqueous systems, can have a configuration based on a rotating laundry basket or drum that defines a drum opening and a treating chamber in which laundry items are placed for treating according to one or more cycles of operation. The laundry treating appliance can include a cabinet including a panel with an access opening through which clothes are loaded and unloaded into the treating chamber. A door assembly can be movably mounted to the cabinet to selectively open and close the access opening to the treating chamber. The door assembly can include multiple door components, such as a transparent or partially transparent viewing window, a hinge assembly, and a user interface for the laundry treating appliance. A bellows can be provided to extend at least partially between the access opening and the drum opening.
In one aspect, the present disclosure relates to a laundry treating appliance comprising a chassis defining an interior and having a front panel defining a front panel opening, a rotatable treating chamber located within the interior and having a treating chamber opening at a lower height than the front panel opening, yet still accessible through the front panel opening, and a door assembly mounted to the chassis for movement between opened and closed positions to selectively open or close the front panel opening and movable from the closed position to the opened position from within the treating chamber, the door assembly comprising a window aligned with the front panel opening when the door assembly is in the closed position, and the window is slidable between a closed position, where it closes the front panel opening, and an opened position, where it provides access to the front panel opening.
In another aspect, the present disclosure relates to a laundry treating appliance comprising a chassis defining an interior and having a front panel defining a front panel opening, a rotatable treating chamber located within the interior and having a treating chamber opening at a lower height than the front panel opening, yet still accessible through the front panel opening, and a door assembly mounted to the chassis for movement between opened and closed positions to selectively open or close the front panel opening and movable from the closed position to the opened position from within the treating chamber, the door assembly comprising a window aligned with the front panel opening when the door assembly is in the closed position, and the window is slidable between a closed position, where it closes the front panel opening, and an opened position, where it provides access to the front panel opening.
In the drawings:
Laundry treating appliances are typically categorized as either a vertical axis laundry treating appliance or a horizontal axis laundry treating appliance. As used herein, the term “horizontal axis” laundry treating appliance refers to a laundry treating appliance having a rotatable drum that rotates about a generally horizontal axis relative to a surface that supports the laundry treating appliance. 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 laundry treating appliance, the term “vertical axis” laundry treating appliance refers to a laundry treating appliance having a rotatable drum that rotates about a generally vertical axis relative to a surface that supports the laundry treating appliance. 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” laundry treating appliance refers to a laundry treating appliance having a rotatable drum, perforate or imperforate, that holds fabric items and, optionally, a clothes mover, such as an agitator, impeller, nutator, and the like within the drum. The clothes mover can move within the drum to impart mechanical energy directly to the clothes or indirectly through wash liquid in the drum. The clothes mover can typically be moved in a reciprocating rotational movement. In some vertical axis laundry treating appliances, the drum rotates about a vertical axis generally perpendicular to a surface that supports the laundry treating appliance. However, the rotational axis need not be vertical. The drum can rotate about an axis inclined relative to the vertical axis.
As used herein, the “horizontal axis” laundry treating appliance refers to a laundry treating appliance having a rotatable drum, perforated or imperforate, that holds laundry items and washes and/or dries the laundry items. In some horizontal axis laundry treating appliances, the drum rotates about a horizontal axis generally parallel to a surface that supports the laundry treating appliance. 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 laundry treating appliances, 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 laundry treating appliance can be top-loading or front-loading. In a top-loading laundry treating appliance, laundry items are placed into the drum through an access opening in the top of a cabinet, while in a front-loading laundry treating appliance laundry items are placed into the drum through an access opening in the front of a cabinet. If a laundry treating appliance is a top-loading horizontal axis laundry treating appliance or a front-loading vertical axis laundry treating appliance, an additional access opening is located on the drum.
In more detail, the laundry treating appliance 10 of
The laundry holding system of the illustrated laundry treating appliance 10 can include a tub 20 supported within the cabinet 14 by a suitable suspension system, the tub 20 at least partially defining a treating chamber 22 for laundry items. A drum 12 can be provided within the tub 20 to further define at least a portion of the treating chamber 22. The treating chamber 22 is configured to receive a laundry load comprising laundry items 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 front panel opening 18 can provide access to the treating chamber 22. The drum 12 can be either imperforate or perforated, including a plurality of perforations 26 such that liquid can flow between the tub 20 and the drum 12 through the perforations 26. A plurality of baffles 28 can be disposed on an inner surface of the drum 12 to lift the laundry load received in the treating chamber 22 while the drum 12 rotates. It will be understood that it is also within the scope of the present disclosure for the laundry holding system to comprise only the tub 20, without a drum, to define the treating chamber 22. The laundry treating appliance 10 can further include a suspension system 30 for dynamically suspending the laundry holding system within the structural support system.
The tub 20 can also define a tub opening 24, which can be thought of as a treating chamber opening and which can be at least partially aligned with the front panel opening 18 of the cabinet 14. In one example, the tub 20, along with the tub opening 24, the drum 12, and the front panel opening 18 can have central axes that are co-axial with one another, or with at least one of the other axes, such that a common central axis X is formed. Optionally, and especially in the case that the laundry treating appliance 10 is provided as a washing machine, rather than a clothes dryer, a bellows 50 can extend between the tub opening 24 and the front panel opening 18 to couple the front panel opening 18 of the cabinet 14 with the tub opening 24 of the tub 20. The bellows 50 can sealingly couple the tub opening 24 and the front panel opening 18 such that liquid is not permitted to move from the tub 20 into the interior of the cabinet 14.
A door assembly 100 can be included with the laundry treating appliance 10. The door assembly 100 can be movably mounted or coupled to the cabinet 14. By way of non-limiting example, the door assembly 100 can be hingedly coupled to the cabinet 14 for movement between an opened condition (
Optionally, and, for example, in the case that the laundry treating appliance 10 is provided as a washing machine, the laundry treating appliance 10 can further include a liquid supply system for supplying water to the laundry treating appliance 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 31, which can include separate valves 32 and 33 for controlling the flow of hot and cold water, respectively. Water can be supplied through an inlet conduit 34 directly to the tub 20 by controlling first and second diverter mechanisms 35 and 36, respectively. The diverter mechanisms 35, 36 can be a diverter valve having two outlets such that the diverter mechanisms 35, 36 can selectively direct a flow of liquid to one or both of two flow paths. Water from the household water supply 31 can flow through the inlet conduit 34 to the first diverter mechanism 35 which can direct the flow of liquid to a supply conduit 37. The second diverter mechanism 36 on the supply conduit 37 can direct the flow of liquid to a tub outlet conduit 38 which can be provided with a spray nozzle 39 configured to spray the flow of liquid into the tub 20. In this manner, water from the household water supply 31 can be supplied directly to the tub 20. While the valves 32, 33 and the conduit 34 are illustrated exteriorly of the cabinet 14, it will be understood that these components can be internal to the cabinet 14.
The laundry treating appliance 10 can also optionally be provided with a dispensing system for dispensing treating chemistry to the treating chamber 22 for use in treating the laundry according to a cycle of operation. The dispensing system can include a treating chemistry dispenser 65 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 22. The treating chemistry dispenser 65 can be configured to dispense a treating chemistry directly to the tub 20 or mixed with water from the liquid supply system through a dispensing outlet conduit 40. The dispensing outlet conduit 40 can include a dispensing nozzle 41 configured to dispense the treating chemistry into the tub 20 in a desired pattern and under a desired amount of pressure. For example, the dispensing nozzle 41 can be configured to dispense a flow or stream of treating chemistry into the tub 20 by gravity, i.e. a non-pressurized stream. Water can be supplied to the treating chemistry dispenser 65 from the supply conduit 37 by directing the diverter mechanism 36 to direct the flow of water to a dispensing supply conduit 42.
The treating chemistry dispenser 65 can include multiple chambers or reservoirs fluidly coupled to the treating chamber 22 for receiving doses of different treating chemistries. The treating chemistry dispenser 65 can be implemented as a dispensing drawer that is slidably received within the cabinet 14, or within a separate dispenser housing which can be provided in the cabinet 14. The treating chemistry dispenser 65 can be moveable between a fill position, where the treating chemistry dispenser 65 is exterior to the cabinet 14 and can be filled with treating chemistry, and a dispense position, where the treating chemistry dispenser 65 is interior of the cabinet 14.
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 laundry treating appliance 10 can also optionally include a recirculation and drain system for optionally recirculating liquid within the laundry holding system and for draining liquid from the laundry treating appliance 10. Liquid supplied to the tub 20 through tub outlet conduit 38 and/or the conduit 40 typically enters a space between the tub 20 and the drum 12 and can flow by gravity to a sump 43 formed in part by a lower portion of the tub 20. The sump 43 can also be formed by a sump conduit 44 that can fluidly couple the lower portion of the tub 20 to a pump 45. The pump 45 can direct liquid to a drain conduit 46, which can drain the liquid from the laundry treating appliance 10, or to a recirculation conduit 47, which can terminate at a recirculation inlet 48. The recirculation inlet 48 can direct the liquid from the recirculation conduit 47 into the drum 12. The recirculation inlet 48 can introduce the liquid into the drum 12 in any suitable manner, such as by spraying, dripping, or providing a steady flow of liquid. In this manner, liquid provided to the tub 20, with or without treating chemistry, can be recirculated into the treating chamber 22 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 20, such as a steam generator 49 and/or a sump heater 51. Liquid from the household water supply 31 can be provided to the steam generator 49 through the inlet conduit 34 by controlling the first diverter mechanism 35 to direct the flow of liquid to a steam supply conduit 52. Steam generated by the steam generator 49 can be supplied to the tub 20 through a steam outlet conduit 53. The steam generator 49 can be any suitable type of steam generator 49 such as a flow through steam generator or a tank-type steam generator. Alternatively, the sump heater 51 can be used to generate steam in place of or in addition to the steam generator 49. In addition or alternatively to generating steam, the steam generator 49 and/or sump heater 51 can be used to heat the laundry and/or liquid within the tub 20 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 laundry treating appliance 10 also includes a drive system for rotating the drum 12 within the tub 20. The drive system can include a motor 54 for rotationally driving the drum 12. The motor 54 can be directly coupled with the drum 12 through a drive shaft 55 to rotate the drum 12 about a rotational axis during a cycle of operation. The motor 54 can be a brushless permanent magnet (BPM) motor having a stator 56 and a rotor 57. Alternately, the motor 54 can be coupled with the drum 12 through a belt and a drive shaft to rotate the drum 12, 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 54 can rotationally drive the drum 12 including that the motor 54 can rotate the drum 12 at various speeds in either rotational direction.
The control system can control the operation of the laundry treating appliance 10 to implement one or more cycles of operation. The control system can include a controller 58 located within the cabinet 14 and a user interface 59 that can be operably coupled with the controller 58. The user interface 59 can provide an input and output function for the controller. The user interface 59 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 laundry treating appliance 10 and can allow the controller 58 to communicate with the user in a variety of ways. For example, the controller 58 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 laundry treating appliance 10 or utilizing another device such as a mobile phone.
The controller 58 can include the machine controller and any additional controllers provided for controlling any of the components of the laundry treating appliance 10. For example, the controller 58 can include the machine controller and a motor controller. Many known types of controllers can be used for the controller 58. 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 58 can be operably coupled with one or more components of the laundry treating appliance 10 for communicating with and controlling the operation of the component to complete a cycle of operation. For example, the controller 58 can be operably coupled with the motor 54, the pump 45, the treating chemistry dispenser 65, the steam generator 49 and the sump heater 51 to control the operation of these and other components to implement one or more of the cycles of operation
The controller 58 can also be coupled with one or more sensors 63 provided in one or more of the systems of the laundry treating appliance 10 to receive input from the sensors 63, which are known in the art and not shown for simplicity. Non-limiting examples of sensors 63 that can be communicably coupled with the controller 58 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.
In the case that the window panel 110 is slidably moveable within the door assembly 100, as illustrated herein, the hinged movement of the door assembly 100 relative to the cabinet 14 can serve to satisfy Underwriters Laboratories (UL) safety standards. The window panel 110 can be configured such that a user lowers the window panel 110 entirely to the lowered position in order to load laundry items into the treating chamber 22 through the entire access opening 102 and brings the window panel 110 to the raised position when loading has been completed and in preparation for the cycle of operation. Additionally, the door assembly 100 can be opened by applying a pushing force or pressure from within the treating chamber 22 or pulling force or pressure from an exterior of the laundry treating appliance 10 on the door assembly 100 to move the door assembly 100 from the closed condition to the opened condition. In this way, the desired user experience of loading laundry items into the treating chamber 22 via the slidable window panel 110 can be preserved, while still satisfying safety standards by the provision of the hingedly movable door assembly 100.
In one example, the bellows 50 can protrude slightly beyond the front panel opening 18 such that the bellows 50 can contact and resiliently bear against the door assembly 100 when the door assembly 100 is in the closed condition to provide a sealing engagement between the bellows 50 and the door assembly 100. In one specific example, the bellows 50 can resiliently bear against the window panel 110 when the door assembly 100 is in the closed condition and the window panel 110 is in the raised position. Alternately, the bellows 50 can resiliently bear against the door assembly 100 outside of the circumference of the window panel 110 such that the bellows 50 seals against the door assembly 100 regardless of whether the window panel 110 is in the raised position or the lowered position. When a bellows 50 is not provided with the laundry treating appliance 10, a gasket seal can resiliently bear against the window panel 110 when the door assembly 100 is in the closed condition and the window panel 110 is in the raised position.
The window panel 110 can include a see-through panel or window, as well as a grip or a handle 112. The window panel 110 can be formed of glass, plastic, or other suitable material. It will also be understood that the window panel 110 can include multiple sliding panels, including an outer panel that can be configured to protect the user from the motion of the drum or tub 20 and an inner panel that seals the treating chamber 22. The handle 112 can provide an outwardly or inwardly protruding formation that a user can grip in order to slide the window panel 110 between the raised and lowered positions. When the window panel 110 is in the raised position, the window panel 110 can be held in the raised position by any suitable latching mechanism, non-limiting examples of which include a snap fit or an interference grip. It will be understood that the window panel 110 can be slid in any suitable manner, including through the use of tracks or through an electrical sliding mechanism. Further, the window panel 110 can be slid in any suitable direction to open and close the access opening 102 of the treating chamber 22, including that the window panel 110 can be slid sideways, downwards, or upwards.
The sliding of the window panel 110 can be implemented in any suitable manner, including that the window panel 110 can be manually moved, or that an actuator (not shown) can be provided and configured to automatically move the window panel 110 between raised and lowered positions by way of operable coupling with the controller 58. The actuator can move the window panel 110 toward the raised or lowered position in response to user input or in response to input from the controller 58 of the laundry treating appliance 10. Any suitable type of actuator could be coupled with the window panel 110, non-limiting examples of which include a motor or a biasing device, such as a spring.
By vertically shifting the front panel opening 18 and the access opening 102 upwardly relative to the tub 20, the user's view to the rear and the bottom of the treating chamber 22 is improved. Further, the upward shift of the access opening 102 allows a greater height within which the window panel 110 can slide downward within the door assembly 100, allowing the window panel 110 to slide downward and be completely received within the door assembly 100 to the extent that the handle 112 is still accessible to the user. If the access opening 102 were not shifted upward, the portion of the door assembly 100 may not have a height sufficient for the window panel 110 to slide downward completely within the door assembly 100, resulting in a portion of the window panel 110 partially blocking the access opening 102 and creating an inconvenience for the user. Further still, the angled bellows 150 can obviate the need for a bowl portion of the door window as is seen in conventional laundry treating appliances such as washing machines. The bowl portion can be provided to prevent laundry items from becoming stuck on the bellows 150 or from applying pressure against the door assembly 100. When the access opening 102 and front panel opening 18 are vertically shifted upward relative to the tub opening 24, the bowl portion may no longer be needed as the angle of the angled bellows 150 can be sufficient to encourage laundry items to fall back toward the treating chamber 22 due to gravity alone.
The bellows 50 can further define a visual portion 60 that faces towards and is viewable by the user. As the bellows 50 angles downwardly from the front panel opening 18 to the tub opening 24, the bellows 50 defines the visual portion 60 at an upper portion of the bellows 50 that is visible to the user. The visual portion 60 can be used to provide a pleasing visual effect to the user, such as a decorative pattern. Such a decorative pattern can be formed in the bellows 50 in a three-dimensional manner, or provided as a decorative panel, printed applique, wrapper, or insert to couple to the visual portion 60 of the bellows 50. Warning labels, safety labels, or other user instructions could also be provided on the visual portion 60.
The bellows 50 can be formed from a flexible or pliable material, such as a rubber. In one example, the deflecting element 70 can be formed from a material that is more rigid than the material of the bellows 50. It will be understood that the deflecting element 70 can be formed from a material that is either rigid or non-rigid, such as flexible, so long as the material of the deflecting element 70 has sufficient strength to withstand an impact of wet laundry items that may be traveling at high speeds, such as at spin speeds during a spin phase of the cycle of operation. Further, the deflecting element 70 can be formed of or coated on an outer surface with a material having a low coefficient of friction, such as a coefficient of friction lower than that of the bellows 50, in order to further encourage laundry items to slide along the angled bellows 50 and back into the treating chamber 22, rather than resting on or becoming stuck within or to the bellows 50. By way of non-limiting example, the deflecting element 70 can be formed of marine grade foamed vinyl or a polyvinyl chloride (PVC)-coated closed cell foam. While the deflecting element 70 is illustrated herein as being provided along a lower portion of the bellows 50, it will be understood that the deflecting element 70 can be provided along any suitable portion of the bellows 50, non-limiting examples of which include the entire lower half of the bellows 50, or about the entire circumference of the bellows 50.
A set of spray outlets 80 can optionally be provided within the deflecting element 70, which can include any suitable number of spray outlets 80, including only a single spray outlet 80. Any of the previously described spray nozzles 39, dispensing nozzle 41, or the recirculation inlet 48 can be provided within or passing through the deflecting element 70, or the spray outlets 80 provided within or passing through the deflecting element 70 can be separate spray outlets 80 that are fluidly coupled with the liquid supply system. Alternately, or in addition to, the spray outlets 80, at least one light can be provided within or along the deflecting element 70. The light can be provided as, by way of non-limiting example, an LED bulb protruding from or embedded within the deflecting element 70, or an edge lighting array along an edge of the deflecting element 70. It will be further understood that, in aspects of the present disclosure wherein the deflecting element 70 is not included, either or both of the light or spray outlets 80 can be provided directly in the bellows 50, rather than in the deflecting element 70.
The aspects of the present disclosure provide a laundry treating appliance having a variety of features providing benefits to the user. In one example, a slidable window is provided such that a user can load laundry into the treating chamber via the slidable window. Along with the slidable window, a hinged door assembly can be provided so that the laundry treating appliance will still meet UL safety standards for entrapment by having a hinged door that can be kicked or pushed open, while allowing normal laundry loading to occur through a slidable window. Further, the hinged door assembly allows the user to clean the rear or inner surface of the slidable window without having to try to reach through the partially opened slidable window to do so. Further still, the access opening can be vertically upwardly offset relative to the opening of the tub, with or without an angled bellows extending between the vertically offset openings. The angled bellows can encourage laundry items to slide downwardly off of the angled bellows and back into the treating chamber without the need for an inwardly protruding bowl associated with the slidable window and while improving user visibility into the treating chamber, in particular to the lower rear portions of the treating chamber. By encouraging laundry items to slide along the angled bellows rather than becoming stuck on or in the bellows, standing water in the bellows that can result in an unpleasant odor can also be avoided. In the case that a bellows is not included with the vertically offset openings, improved visibility to the treating chamber is still achieved, as well as providing the room necessary for the window panel to be lowered all the way to the lowered position within the door assembly, as well as allowing for matched styling between the window panel height of, for example, a washing machine with an angled bellows and a clothes dryer with vertically offset openings, but no bellows.
To the extent not already described, the different features and structures of the various aspects of the present disclosure 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. For example, the slidable window panel can be employed with or without the angled bellows and the vertically offset access opening, spray outlets and nozzles can be provided with or without an angled bellows or a deflecting element, or the angled bellows and vertically offset access opening can be provided with or without the slidable window and/or the hinged door assembly. Thus, the various features of the different aspects of the present disclosure 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. 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.
