  • the liquid discharged from the pump such as the washing water of a dishwasher or a washing machine, is often soiled with hair, particles, fibers or the like.
  • the impeller is rotated for liquid discharge at a high speed in the hydraulic chamber, wherein the liquid contained in the hair, particles, fibers or the like.

  • the object of the present invention is to provide a structurally improved pump for discharging a liquid with which the operational drainage capacity of a liquid drainage pump can be ensured.
  • the object is achieved by a pump for discharging a liquid with an engine compartment, an electric motor having a drive shaft and is located in the engine compartment, and an impeller which is attached to the drive shaft, wherein between a front end cap of the engine compartment and the Impeller an axial clearance is present. It is provided that in the front end cap of the engine compartment an annular groove and on the impeller in the direction of the annular groove extending, annular impeller extension is formed.
  • annular impeller extension and the matched annular groove is achieved during a high-speed rotation of the impeller in the liquid during operation of the pump for discharging a liquid that the hair, particles, fibers or the like contained in the liquid.
  • Difficult with the Rotary movement of the impeller can pass through a formed by the annular impeller extension and the tuned annular groove in the axial clearance between the front end cap of the engine compartment and impeller. In this way, it is possible to prevent such foreign bodies from accumulating or winding on the drive shaft or around the drive shaft, thus preventing an operational high-speed rotation of the drive shaft and impairing the drainage performance of the pump.
  • the impeller simultaneously reciprocates axially during high speed rotation with the drive shaft, and with the annular groove in the front end cap, greater space for the axial reciprocation of the impeller can be created to provide contact between the annular impeller extension and to avoid front end cap.
  • both the annular impeller extension of the impeller and the matched annular groove can be provided in an amount of more than one.
  • one or more additional annular impeller extensions and within the annular groove also one or more additional, correspondingly arranged annular grooves may be provided the annular impeller projections each protrude axially into an associated annular groove.
  • the annular impeller extension projects axially into the annular groove.
  • the axial clearance has an axial width which is at least greater than 1.5 mm.
  • the axial width of the axial clearance is between 1.5 mm and 3.5 mm.
  • the annular impeller extension extends axially in the direction of the front end cap of the engine compartment by a predetermined amount.
  • the annular groove is formed in a surface of the front end cap of the engine compartment.
  • annular end cap extension arranged around the annular groove is additionally formed on the front end cap of the engine compartment and extends axially by a predetermined amount.
  • a radial clearance is present between the annular Endkappenfortsatz and annular impeller extension.
  • the radial clearance, the annular groove and the axial play are connected to form a curved channel.
  • the curved channel comprises at least a first and a second corner.
  • both the first and the second corner have an angle of approximately 90 degrees.
  • the curved channel initially extends axially in a direction pointing to the front end cap direction to the first corner and then in the longitudinal direction to the second corner. This in turn is followed by an axial extension in a direction away from the front end cap direction. This results in an even curvilinear curved channel, which makes it even harder that in the Hair, particles, fibers or the like contained. Liquid discharged through this channel in the axial play between the front end cap of the engine compartment and impeller and accumulate or wind on the drive shaft or to the drive shaft.
  • a plurality of annular grooves may be formed in the front end cap and a plurality of annular vane extensions may be formed on the impeller, so that the curved channel has a longer course and more similar first and second corners.
  • the annular groove has a greater radial width than the annular impeller extension.
  • the annular groove has a radial width which is larger by 1-4 mm than the radial width of the annular impeller extension.
  • annular impeller extension protrudes into the annular groove, so that the curved channel described above arises. Moreover, in the high-speed rotation of the impeller, a free rotational movement of the annular impeller extension is made possible in the annular groove.
  • the annular impeller extension has an axial length which is greater than the axial width of the axial clearance.
  • the annular impeller extension has an axial length which is greater by 1.5-4 mm than the axial width of the axial clearance.
  • the annular impeller extension can axially exceed the axial clearance to project into the annular groove and thereby produce the curved channel described above.
  • the impeller is mounted on the drive shaft so that when sliding the impeller on the drive shaft between the impeller and the front end cap of the engine compartment, the axial play arises.
  • the impeller, the annular impeller extension and the annular groove are arranged concentrically with each other.
  • the pump for discharging a liquid is a centrifugal pump for draining water.
  • the invention further proposes a household appliance operated with water, in particular a dishwasher or a washing machine, which comprises a pump for discharging a liquid according to one of the preceding embodiments.
  • the in FIG. 1 illustrated dishwasher GS includes a serving as a washing container interior IR, which is by a door (not labeled) can be opened or closed, wherein the door for the purpose of loading or unloading is pivotally connected to the dishwasher GS.
  • a dish rack GK is arranged for receiving an object to be cleaned, which is removable from the interior IR of the dishwasher GS, in order to simplify the loading or unloading.
  • a spray device in the form of a spray arm SA for applying a fluid to the object to be cleaned is installed in the interior IR of the dishwasher GS, wherein the fluid may be filled with e.g. a cleaning or rinsing agent may be mixed with water to allow cleaning and / or spotless drying of the object to be cleaned.
  • the fluid dripping from the object to be cleaned is collected in a pump sump PS located in a bottom portion of the interior IR of the dishwasher GS.
  • a filter device (not labeled) is installed, with the impurities or particles can be cut out of the circulating fluid.
  • the spray arm SA is flow-connected via a supply line ZL with a circulation pump UP, which is located in the vicinity of the other dishwasher components of a arranged below the interior IR of the dishwasher GS bottom part BO.
