Definitions

  • a selectively openable cover illustrated herein as comprising a lid 28 can be movably mounted to the cabinet 14 for selective movement between an opened position and a closed position to selectively open and close the access opening 15 and to provide access into the laundry treating chamber 32 through the access opening 15 of the basket 30.
  • a laundry mover 38 can be rotatably mounted within the basket 30 to impart mechanical agitation to a load of laundry placed in the basket 30.
  • the laundry mover 38 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 32.
  • Other exemplary types of laundry movers include, but are not limited to, an agitator, a wobble plate, and a hybrid impeller/agitator.
  • liquid supply system and treating chemistry dispenser 54 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 10 and for the introduction of more than one type of detergent/wash aid.
  • the illustrated drive system, suspension system, liquid supply system, recirculation and drain system are shown for exemplary purposes only and are not limited to the systems shown in the drawings and described above.
  • the liquid supply, recirculation and pump systems can differ from the configuration shown in FIG. 1 , such as by inclusion of other valves, conduits, sensors (such as liquid level sensors and temperature sensors), and the like, to control the flow of liquid through the washing machine 10 and for the introduction of more than one type of treating chemistry.
  • the liquid supply system can be configured to supply liquid into the interior of the tub 34 not occupied by the basket 30 such that liquid can be supplied directly to the tub 34 without having to travel through the basket 30.
  • the liquid supply system can include a single valve for controlling the flow of water from the household water source.
  • the recirculation and pump system can include two separate pumps for recirculation and draining, instead of the single pump as previously described.
  • the plurality of barrier ribs 106 can be circumferentially spaced about the body 102 and about the deflectable fingers 110 to extend downwardly from the portions of the circumference of the cap portion 104 between the opposing retaining ribs 108.
  • the barrier ribs 106 can be evenly spaced between the opposing retaining ribs 108, or the barrier ribs 106 can vary in their spacing along the circumference of the cap portion 104 between the opposing retaining ribs 108.
  • the plurality of barrier ribs 106 can be thought of as forming a filter portion of the foreign object barrier 100.
  • the at least a portion of the foreign object barrier 100 that is received within the pump inlet conduit 67 comprises at least a portion of the deflectable fingers 110 that extend through the pump inlet 63 into the pump inlet conduit 67 such that the retaining flanges 112 are received and retained within the retaining openings 79 of the pump inlet conduit 67.
  • the catch surfaces 114 can bear against the retaining openings 79 to prevent upward withdrawal of the foreign object barrier 100 from the pump inlet conduit 67.
  • the engagement between the retaining flanges 112 and the retaining openings 79 can also restrict rotational and/or downward movement of the foreign object barrier 100 relative to the pump inlet conduit 67.
