  • the present invention relates to a drain hose holder for use in a water conducting household appliance, in particular a dishwasher or a clothes washer.
  • a water conducting household appliance such as a dishwasher or a clothes washer generally has a drain hose for draining the washing liquid.
  • a drain hose is usually made of relatively hard plastic and has a corrugated form which lends flexibility. Thereby, the corrugated drain hose can be almost rigidly installed into the water conducting household appliance and flexibly connected to a main drainage pipe.
  • Conventional corrugated drain hoses come in different types.
  • a commonly known corrugated drain hose has a plurality of sequentially and coaxially formed ridges and valleys which are circularly shaped.
  • Another commonly known corrugated drain hose has a plurality of sequentially and helically formed ridges and valleys.
  • the corrugated drain hose is connected to a drainage pump of the water conducting household appliance.
  • the water conducting household appliance When the water conducting household appliance is taken into operation, the water being drained by the drainage pump exerts a thrust on the corrugated drain hose.
  • the corrugated drain hose is generally secured to the water conducting household appliance, among others, through a corrugated drain hose holder.
  • the corrugated drain hose holder provides strain relief in case the corrugated drain hose is inadvertently pulled out by a user, for example, during installation of the water conducting household appliance.
  • the corrugated drain hose must be safely secured by the corrugated drain hose holder both against radial and longitudinal displacement.
  • US 6,409,223 B1 discloses a holder for securing a corrugated drain hose against longitudinal movement and radial movement.
  • This conventional holder has a cut-out that is open on one side into which a valley of the corrugated drain hose is inserted under elastic deformation.
  • the open side of the cut-out exerts a force onto the surface of the corrugated drain hose at its valley as the valley is being inserted into the cut-out.
  • a drawback of the conventional holder is that if the open side of the cut out is too narrow, than the corrugated drain hose may get damaged at its valley during an insertion and give rise to leakage of the washing liquid.
  • the open side is not suffiently narrow, then the corrugated drain hose can easily move out of the cut-out under the influence of the thrust of the washing liquid and get disconnected from the drainage pump.
  • this conventional holder has a limited safety.
  • An objective of the present invention is to provide a corrugated drain hose holder for use in a water conducting household appliance and a water conducting household appliance having the same which overcomes the aforementioned drawbacks of the prior art in a cost effective way and which enables an improved safety and easy assembly.
  • the drain hose holder of the present invention has a support which includes an arc-shaped first notch into which a valley is insertable without any deformation of the corrugated drain hose.
  • the arc-shaped first notch abuts against opposing inner surfaces of the ridges adjacent to the opposite sides of the valley so as to inhibit a longitudinal movement of the corrugated drain hose.
  • the support of the drain hose holder further includes an arc-shaped second notch into which one or more than one ridge is insertable under elastic deformation of the corrugated drain hose.
  • the arc-shaped second notch abuts against an outer surface of the respective ridge so as to inhibit a radial movement of the corrugated drain hose.
  • the corrugated drain hose has a special shape, namely a predetermined valley and an adjacent predetermined ridge of the corrugated drain hose each has a relatively large width in a longitudinal direction compared to the other valleys and ridges.
  • the predetermined valley is inserted into the arc shaped first notch.
  • the predetermined ridge is located on an inner side of the support which is averted from the outside.
  • one or more than one ridge located on the opposite side of the predetermined ridge with respect to the predetermined valley is inserted into the arc shaped second notch.
  • the valley of the corrugated drain hose subjected to the insertion step has been prevented from undergoing any elastic deformation during the insertion step.
  • the elastic deformation exclusively occurs on a periphery of the corrugated drain hose, namely at the ridges which are, however, more durable against elastic deformations than the valleys.
  • the risk of damaging the corrugated drain hose and a leakage of the washing liquid has been effectively reduced.
  • the strength at which the corrugated drain hose is captivated can be easily adjusted, thus increased by increasing the number of ridges to be inserted into the arc-shaped second notch.
  • the total captivation strength can be increased without increasing a deformation amount per ridge during the insertion step.
  • the corrugated drain hose can be reliably secured against radial movement.
  • a strain relief against inadvertent pulling out has also been improved.
  • the corrugated drain hose can be reliably secured against longitudinal movements.
