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 dispenser 62 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 dispenser 62 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 dispenser 62 from the supply conduit 52 by directing the diverter mechanism 50 to direct the flow of water to a dispensing supply conduit 68.
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 dispensing supply conduit 68 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.
