Definitions

  • the present invention relates to a pump, in particular for dishwashers, comprising a housing comprising a housing bottom, a housing cover and a heater arranged therebetween for heating a rinsing liquid, which forms an annular side wall of the housing, with an arranged in the housing impeller, with respect to the Rotary axis of the impeller in the housing cover axially arranged suction nozzle and with a discharge nozzle.
  • the invention has for its object to provide a simple and inexpensive pump of the type mentioned, which has smaller external dimensions, in particular in the radial direction while avoiding the aforementioned disadvantages.
  • this object is achieved in a pump of the type mentioned by the fact that the discharge nozzle is arranged in the housing cover.
  • the arrangement of the pressure port in the cover allows a reduction in the outer dimensions of the pump in the radial direction relative to the longitudinal axis thereof.
  • the installation space, in particular the required installation height for the pump is reduced.
  • Installation of the pump below the washing container with the longitudinal axis of the pump parallel to the bottom of the washing container saves valuable installation height. As a result, the useful volume of the washing container can be increased.
  • a longitudinal axis of the suction nozzle is arranged at an acute angle to the longitudinal axis of the pressure nozzle
  • the suction can be connected via very short or even without connecting elements directly with a drain at the bottom of the washing and the pressure nozzle with a supply to the spray system. If two connections with the suction and discharge ports are arranged at the sump, additional parts such as hoses and their attachment means can be dispensed with.
  • suction nozzle and discharge nozzle in the lid allows a simple structure of the heater, namely with a tube with closed sen circular cross-section. Elaborate production engineering forming or processing steps for an opening in the heater can thus be omitted. It is thus largely produced using standard parts.
  • the rinsing liquid can be heated more uniformly in a perforation-free tube than in a ring with openings, because a large-area undisturbed flow of the water occurs along the entire tube surface area.
  • Such a tube is also easily replaceable.
  • a tubular side wall also a structurally simple construction of the housing of the pump is also possible, wherein the housing cover and the housing bottom made of plastic and the tubular side wall made of metal can be made separately.
  • the use of plastic allows not only a cost-effective production of the complex geometries of the housing cover and the housing bottom but also a reduction of the total weight of the pump.
  • Plastic is also a poor conductor of heat, so that the transport of the heated rinsing fluid in the pump can be done almost energy loss.
  • the tube of the heating device is advantageously made of metal, since it transmits a maximum of the heating energy to the rinsing liquid due to the good heat conduction properties.
  • the production of the housing cover can also continue to be produced, for example, by injection molding without significant additional expense for the discharge nozzle.
  • the certain existing complexity of the shape of the lid due to the suction is not significantly increased by the additional arrangement of the pressure nozzle.
  • the thermal energy required for heating the rinsing liquid provides, according to the invention, a heating means which is in contact with the pipe of the heating device from the outside.
  • a heating means e.g. Thick film resistors, tubular heaters or heating wires are used, which directly touch the outside of the tube. Since the pipe is free of interruptions, the orientation of the heating means on the pipe is basically freely selectable.
  • the heating means may e.g. in the form of rings arranged parallel to one another, arranged spirally or as flat strips transversely or parallel to the pipe longitudinal axis.
  • the method for applying the heating means to the tube jacket surface for example by printing the tube with the thick-film resistance material is thereby simpler.
  • the heating device can have a temperature sensor, for example an NTC or PTC resistor.
  • the tube may also consist of temperature-resistant plastic, in particular electrically conductive plastic.
  • the heating means may already be integrated into the pipe, so that the application of heating means may be omitted as a production step.
  • the suction nozzle protrudes centrally into the region of the heating device and, with the formation of a radial gap, reaches the front side as far as the impeller.
  • this has the advantage that the rinsing liquid sucked in through the suction nozzle can be selectively guided in a uniform axial flow up to the suction opening of the impeller.
  • During operation of the pump can be done with appropriate heating of the housing parts and thus also of the suction already preheating the sucked through the suction rinse. This effect can be enhanced by additional heating means in or at the suction nozzle.
  • the flow of the scavenging liquid sucked in from the direction of the lid is deflected by 180 degrees in the impeller and then flows spirally coaxially with the sucked-in rinsing liquid in an annular-cylindrical space on the inside of the heating to the lid back.
  • the impeller in an advantageous embodiment of the invention in the direction of the housing cover curved cover plates for deflecting the axially sucked Spülswashkeitsströmung in the axially opposite direction to the discharge nozzle on.
  • the cover plates can be hemispherical curved to deflect the centrally centrally or centrally sucked by the impeller rinsing liquid from the suction nozzle between the cover plates of the impeller almost completely on a curved path by 180 degrees.
  • the outer diameter of the suction nozzle facing the cover plate is smaller than that of the opposite cover plate, since so the rinsing liquid can be optimally deflected into the hollow cylindrical space.
  • blades of the impeller can promote by their shape and arrangement, the deflection of the flow.
  • the vanes can be curved over their entire radial length and in the direction of the pressure-side outlet openings of the impeller. The curvature can be more pronounced at the blade ends in order to convey the flow at the exit from the impeller even more effectively the desired flow direction.
  • a guide device for further flow deflection may consist of stationary vanes, which are arranged annularly downstream of the outlet opening of the Laufrad-.
  • the vanes may easily extend radially in the annular cylindrical space. Its blade surface may be curved to further counteract the swirl of the flow exiting the impeller.
  • the flow component is increased in the axial direction.
  • the guide device is arranged on the lid.
  • the guide can be connected as a separate part fixed to the lid or integrally formed on the lid.
  • a one-piece design requires fewer items and thus cheaper the production of the pump housing.
  • the housing cover has spiral-shaped guide elements for the flow line of the rinsing liquid from the heating device into the discharge nozzle.
  • the guide elements facilitate the transfer of the rinsing liquid from the ring-cylindrical space into the cylindrical discharge nozzle by focusing the flow in the direction of the discharge nozzle.
  • the guide elements are preferably integrally formed in the lid around the suction nozzle in the form of guide spirals. They are to be designed in such a way that the transfer of the rinsing liquid into the discharge nozzle takes place without a significant loss of kinetic energy.
  • the housing cover is therefore at least partially made of an elastomer. This allows the lid to be demoulded non-destructively even with very complex geometries.
  • the elastomeric part of the lid has the ability to largely adapt to the rinsing liquid flow during the deflection from the heating device into the pressure nozzle. As a result, it is possible to dispense with special spiral-shaped guide elements for guiding the flow largely.
  • rigid molded parts can stiffen the housing cover. You can ensure a defined position especially of the suction against the impeller to exclude collisions. In addition, the tightness of a rigid part of the lid z. B. be guaranteed relative to the heater reliable. Sections of the elastic deck are thereby clamped between the tube of the heater and the rigid moldings.
