Definitions

  • the invention relates to a washing machine tub arrangement having a recirculation conduit connecting a recirculation pump housing to a spray nozzle for spraying the recirculated liquid into a drum arranged within the washing machine tub. Further the invention relates to a washing machine having such a washing machine tub.
  • WO 2008/125974 A2 discloses a tub for a washing machine formed of two shells which are welded together to form the closed tub in which the rotatable mounted drum is arranged. Wash liquid recirculating channels are integrally arranged at the washing tub and a pump housing is formed at the sump of the tub.
  • the pump is mounted to the pumping housing and, depending on the position of a valve, the wash liquid sucked from the tub sump is either directed to a drain hose or recirculated into the interior of the drum through wholes formed in the drum.
  • an axially running conduit is in fluid connection with the pressure outlet of the pumping housing.
  • a circumferentially running conduit is formed at the joining interface of the two shell halves.
  • the circumferential conduit is closed when the two shell halves of the tub are welded together.
  • a complex molding tool is required for forming the pump housing and in fluid connection therewith the closed axial conduit.
  • the circumferential conduit formed between shell halves requires a complex welding procedure in which it has to be guaranteed that the junction between the two shell halves at the circumferential conduit are permanently water tight sealed - even under mechanical and thermal stress.
  • DE 199 62 257 A1 proposes a recirculation-type washing machine in which the recirculated washing liquid is directly injected into the drum.
  • a water distribution chamber is arranged around a shaft bearing at the side wall of a tub at which the shaft of the drum is supported.
  • the liquid chamber surrounding the shaft bearing is in fluid communication with a recirculation pump, wherein a hose is connecting the pump and the circular liquid chamber.
  • the hose is running along the inner side wall of the tub between the tub and the drum.
  • the hose and the wash liquid chamber around the shaft bearing require extra space between the side wall of the tub and the drum.
  • a washing machine tub arrangement having a tub is provided for storing in its interior washing liquid or liquor used to wash laundry, and for housing a drum within the tub.
  • the tub arrangement may be provided for a top-loader washing machine having an opening at the upper side for loading the laundry from above, or may be for a front-loader washing machine for loading the laundry through a front opening.
  • the drum rotation axis may be a horizontal axis (front- and top-loader models) or a vertical axis (top-loader), or may have a drum rotation axis deviating some degrees from the horizontal or vertical direction.
  • a pump housing for receiving a recirculation pump (i.e. at least a portion of the recirculation pump) is arranged at the tub.
  • the pump housing comprises a pumping cavity in fluid connection to a bottom region of the tub, preferably a sump of the tub.
  • the pump housing is a portion of the wall of the tub and more preferably is formed with the tub material as a unitary piece, for example by injection molting.
  • the recirculation pump is at the same time a draining pump wherein for example a valve is used to switch between wash liquid recirculation into the drum or draining the wash liquid to the outside of the washing machine.
  • a separate draining pump is provided to drain the wash liquid out of the tub.
  • a recirculation conduit provides a liquid connection between the pumping cavity, in particular the pressure outlet opening of the pumping cavity, to at least one outlet element arranged in the tub and which supplies the liquid into the tub.
  • the at least one outlet element is arranged at the side wall or the circumferential wall of the tub and faces the drum arranged in the tub.
  • the opening of the at least one outlet element is facing at least one opening in the drum such that the recirculated liquid is directly sprayed into the drum's interior.
  • the at least one outlet element can be in liquid communication with a hollow shaft at which the drum is rotated so that the washing liquid can pass through the hollow shaft into the interior of the drum.
  • the at least one outlet element can be in liquid communication with a chamber formed between the drum and the side wall of the tub such that the recirculated washing liquid can flow into the drum through openings arranged at the drum's side of the liquid chamber.
  • Claim 1 provides that the recirculation's conduit is at least partially formed or arranged at the inner surface of the tub, preferably the recirculation conduit is completely formed at the inner surface of the tub over its length from the pumping cavity to the at least one outlet element.
  • the recirculation conduit is correspondingly arranged at the interior of the tub such that even if the recirculation conduit has a leakage, the recirculated washing liquid is not leaking to the outside of the tub, but to the interior of the tub where the washing liquid is stored anyway.
  • the recirculation conduit comprises a cover member that is mounted or mountable to the inner surface of the tub such that when the cover member is mounted, at least a portion of the conduit, preferably all or essentially all of the length of the recirculation conduit is formed between the inner surface portion of the tub covered by the cover member and the inner surface of the cover member itself.
  • a conduit having a flat internal extension from the tub inner wall is provided that can be easily arranged in a small gap between the inner side walls and/or circumferential wall of the tub and the rotating drum's outer surface.
  • the conduit can have a complex geometry according to the tub's internal surface geometry in that the cover member is easily adapted to mate with the inner surface geometry of the tub.
  • the material of the tub and the material of the cover member are identical, but according to the need and for manufacturing optimization, different materials can be used for the tub and the cover member.
  • the cover member may be formed of a thin metal sheet such that the internal extension of the conduit formed by the inner surface and the cover member is further reduced.
  • the tub material may be rigid or semi-rigid, while the material of the cover member is more flexible and elastic such that in the mounting process the form of the cover member can be easily adapted to the connection or junction line at the inner surface of the tub.
  • the material or wall thickness of the cover member - at least over an essential portion of the area of the cover member - is less than the material thickness of the tub. In this case the mechanical stability is provided by the tub, while the cover member only has water guiding function and thus may be thinner than the tub material.
  • the length of the recirculation conduit from the pumping cavity or close to the pumping cavity to the outlet element is formed as far as possible by the opposing surfaces of the inner surface portion of the cover member and the inner surface portion of the tub. Thereby a complex geometry of the molding tool is not necessary. Additionally or in an alternative embodiment no separate or additional sealing means or material is provided to seal between the cover member and the inner surface, in particular the conduit formed by cover member and inner surface is free of any gasket.
  • an open channel or groove is formed that has a depth extension to contribute to the cross section of the conduit.
  • the cover member can be completely flat such as to cover only the open channel or groove in the tub wall. More preferably the cover has also at least a moderate open channel or groove such that when the cover member is mounted at the inner surface of the tub, a portion of the conduit's cross section is contributed by the groove or channel in the tub and another portion is contributed by the channel or groove of the cover member.
  • the channel or groove in the cover member provides the cross section of the conduit and the inner surface of the tub only provides a lid or closure side wall of the conduit.
  • the cover member is welded or bonded to the inner surface of the tub by ultrasonic techniques.
  • the cover member can be fixed at the inner wall of the tub by screwing, adhesive bonding or a snap-fit connecting.
  • the mechanical connection between the cover member and the tub interior can be made by one, two, three, four or more spot connections, by one, two, three, four or more extended line connections or by a connection running at least over extended portions of the junction line or connection line between the cover member and the inner surface of the tub.
  • an ultrasonic weld connection can be made all along the junction or interface between cover member and tub on one or both sides of the cover member.
  • a snap-fit connection can be provided all along the length between cover member and the tub - for example like a snap-fit connection between the cover and the channel of a cable conduit.
  • it can be provided that no separate connection between the tub and the cover member is required, for example if one or both end portions of the cover member are snap-fitted or flanged to the at least one outlet element and/or the pressure side outlet of the pumping cavity, respectively.
  • a snap connection element is formed along at least a portion of the length of the cover member and the inner surface comprises a mating connection element mating with the snap connection element to form a snap connection mounting between the inner surface of the tub and the cover member.
  • the outlet element is formed by a portion of the inner surface or inner structure of the tub and/or an end section of the cover member.
  • the inner surface or inner structure of the tub may provide a mounting element or flange element onto which or into which the end of the cover member is inserted.

  • a first and/or second retaining element is arranged at the inner surface or inner structure of the tub adapted to retain a first end and/or second end of the cover member, respectively, than the mounting process for mounting the cover member on the inner surface of the tub is simplified in that the first end and/or the second end portion of the cover member is just inserted into or snap connected to the respective first and/or second retaining element.
  • a first and/or second flange element is provided at a respective end portion of the cover member adapted to be connected to a mating flange element provided at the pump cavity and/or at the outlet element, respectively.
  • the flange element also provides a connection element between the cover member and the interior structure of the tub such that the fluid connection, preferably a sealed fluid connection, is provided between the pumping cavity and/or outlet element, respectively.
  • a fluff filter is arranged within the tub to filter fluff and particles from the washing liquid.
  • the filter can for example be arranged in a suction path lying between the pumping cavity of the pump and the drum interior, for example when the filter is arranged in the sump of the tub.
  • the filter can be removed and cleaned by the user for example through an opening accessible from the outside of the washing machine and having a sealed lid at the bottom of the tub.
  • the filter can be removed through a filter opening in the drum by user access through the drum, wherein the opening in the drum to the filter location can be covered by a removable lid or preferably by a movable lifter.
