Definitions

  • the invention relates to a pump, in particular a circulation pump for household machines such as dishwashers or similar machines in the preamble of the claim 1 specified Art.
  • the present invention is based on the object the manufacturing and assembly costs for a pump, in particular for a circulation pump in household machines reduce customer-specific adaptability.
  • the life of the pump should also be better Cooling of the drive motor can be increased. This task is characterized by those in claim 1 Features resolved.
  • the lower part of the pump housing is not ribbed stiffly must, it can be manufactured and assembled more cheaply become.
  • the lower part of the pump housing can due to its both on the outer edge and in the middle of the A-side end shield of the motor housing are supported.
  • the elastic design of the lower part of the pump housing is further favored by the fact that the sealing ring, that between the upper part of the pump housing and the lower part of the pump housing is arranged sealingly in the radial direction is applied. This will both assembly the pump simplified as well as a relief of Latching means achieved.
  • the locking hooks and locking lugs can be trained weaker. It's also a stiffener of the upper part of the pump housing is not required.
  • the pump is used in particular as a circulation pump for household machines like dishwashers or the like Machines described.
  • 1 shows a pump 1, whose pump housing 3 on the motor housing 5 of a drive motor 7 is flanged.
  • the pump housing 3 is made from a pot-shaped pump housing upper part 9, the both an axial intake 11 and a tangential directed discharge nozzle 13, and one that Pump housing 3 liquid-tight to the drive motor 7 final, designed as a seal carrier pump housing lower part 15.
  • This pump housing lower part is 15 attached to the A-side bearing plate 17 of the motor housing 5.
  • the pump housing 3 is a pump impeller according to Figure 2 19 with different height wings 21 for change the width of the pump impeller 19 or the pump output can be used, the distance s between the Junction 23 of the intake 11 in the pump interior 25 facing wing edges 27 of the pump impeller 19 and the peripheral surface 29 surrounding the mouth 23 of the pump housing 3 remains constant.
  • pump impellers 19 of different widths Pump characteristic curve shifted without changing the characteristic.
  • the pump can be used on various dishwashers with different requirements to the pressure / volume flow ratio only by replacing the pump impeller 19 with different widths adapt in the simplest way. Because besides the pump impeller 19 all other parts of pump 1 are the same Development times shortened and with it the development costs greatly reduced.
  • the pump impeller 19 consists of a closed one Circular disc 31, which on one end face 33 fixed, blade-shaped wing 21 and on the another end face 35 a projecting hub 37 with a Blind hole 39 for attaching the pump impeller 19 on the in the pump interior 25 projecting free end 41 of the drive shaft 43 of the drive motor 7.
  • an insert nut 45 is pressed into the blind hole 39, on a thread 47 on the free end 41 of the drive shaft 43 can be screwed on tightly.
  • the insert nut 45 is provided with a stop flange 51, which on the end face 53 of the hub 37 is tight.
  • the end face 53 has an annular depression 52 for the stop flange 51.
  • the pump housing lower part 15 is designed to be elastic, that after the flanging on the A-side End shield 17 both in the area of the drive shaft 43 and on the outer peripheral edge 55 on the A-side End shield 17 supports.
  • that Pump housing lower part 15 has an annular contact surface 57 for several on the end face 59 in the circumferential direction spaced support domes 61, which in the area of the outer edge 63 of the A-side end shield 17 are attached.
  • the lower part of the pump housing 15 with a concentrically arranged to the contact surface 57 Bearing pin 65 provided, the free end 67 in a bearing recess 69 in the end face 71 of the end shield 17 is stored.
  • the bearing journal 65 on the lower part 15 of the pump housing is from the pump interior 25 with a cup-shaped depression 73 provided, in the bottom surface 75 a through hole 77 for the drive shaft 43 of the Drive motor 7 is arranged.
  • the upper part of the pump housing 9 and the lower part of the pump housing 15 are made liquid-tight in that the Opening edge 85 of the pump housing upper part 9 an annular Has edge recess 87 into which a cylindrical Bearing flange 89 of the lower part 15 of the pump housing can be used, the outer circumferential surface 91 of the Edge recess 87 a sealing ring 93 supported is.
  • This sealing ring 93 is supported on the other hand on its inner circumferential side 95 on a before cylindrical bearing flange 89 of the lower part of the pump housing 15 arranged, reduced in diameter and graded Radially from lateral surface 97. Through this radial Support is not necessary to stiffen the lower part of the pump housing 15 in the longitudinal direction of the drive shaft 43.
  • the transition of the inner peripheral surface 109 is advantageous the cup-shaped pump housing upper part 9 to the pump outlet channel executed with sharp edges.
