Definitions

  • the invention relates to an impeller pump for conveying fluid, in particular as a radial pump, as it can be used for example in a water-conducting device or household appliance such as a dishwasher or a washing machine.
  • From the EP 2150165 B1 is basically a corresponding impeller known. It has a pump housing with a pump chamber and inlet and outlet, which are arranged on a cover of the pump housing. Just above a bottom of the pump chamber, an impeller is arranged, which sits on a rotor shaft of the drive motor, which is arranged below the ground. An outer wall of the pump chamber is heated and the fluid flowing therealong is heated.
  • a pump which is designed as an impeller pump.
  • a pump housing has a pump chamber with inlet and outlet, wherein the inlet is formed in the axial direction in a cover of the pump housing.
  • the outlet is provided approximately at the axial height of the impeller.
  • a heating device to heat pumped water.
  • the invention has for its object to provide an initially mentioned impeller pump, can be solved with the problems of the prior art and in particular it is possible to build an impeller pump easy and usable and space to arrange in a device or household appliance.
  • the impeller pump comprises a pump housing, a pump chamber in the pump housing and an inlet and an outlet on the pump chamber. Furthermore, an impeller or an impeller is provided in the pump chamber, which can basically be formed in a known manner.
  • the impeller is arranged on a drive shaft or rotor shaft and thus connected to a drive motor of the pump, in particular with its rotor.
  • the pump chamber has a pump chamber cover and a pump chamber bottom, wherein these two terms are to be understood widely and essentially cause or represent a conclusion or a delimitation of the pump chamber in the axial direction or represent. But you do not have to form the whole degree.
  • the inlet is arranged, preferably centrally or axially and centrically to a longitudinal central axis of the pump.
  • the drive motor can be arranged under the pump chamber bottom or at least below a central region of a pump chamber bottom, ie in the axial direction adjacent to the pump chamber bottom and away from the pump chamber cover or away from the inlet.
  • the outlet from the pump chamber is arranged in the axial direction of the pump below the impeller or impeller, preferably therefore at the end region of the pump chamber near the outlet, which is remote from the inlet in the axial direction.
  • Inlet and outlet are arranged together in the pump chamber lid.
  • the impeller runs over the bottom of the pump chamber.
  • the inlet and outlet are approximately at the same axial height, away from the impeller, or else the outlet may be remote from the impeller in the axial direction beyond the inlet.
  • the outlet is displaced in the axial direction, advantageously the pump chamber, so to speak with him.
  • the outlet is displaced in the axial direction away from the pump chamber cover or away from the inlet, particularly advantageously away from the impeller, but just in the opposite axial direction from the inlet.
  • the pump chamber may preferably also extend annularly in the axial direction of the pump from the impeller, in a direction away from the inlet and advantageously in a direction in which the fluid to be delivered flows into the pump chamber in the inlet.
  • a heating device for the pumped by the pump fluid is provided.
  • This heating device can be integrated into the pump chamber, so that it is directly flown by the fluid conveyed or in the pump chamber.
  • a heating device may advantageously be designed to be circular in shape. In this case, they can form a pump chamber outer wall, since a particularly good flow with particularly good heat transfer is ensured here in a radial pump by the circulation movement of the funded fluid.
  • the impeller may advantageously be arranged just below the pump chamber lid. Thus, it can also be arranged just below the inlet.
  • the pump chamber cover actually covers substantially the end face of the pump chamber and also the entire end face of the pump chamber in the axial direction to the inlet. In the case of the initially mentioned prior art, this is the case for the pump chamber bottom.
  • the pump chamber may extend from the pump chamber cover in the axial direction away from the inlet, advantageously substantially circular in shape.
  • a pump chamber length may be 0.5 times to 1.5 times or even 2.5 times the largest diameter of the pump chamber.
  • the maximum axial extent of the pump chamber length is approximately as large as the largest diameter.
  • the pump chamber length along the axial direction may be 2 to 5 times the axial length of the impeller. This also means that the pump chamber has a certain axial length. This is also needed so that the aforementioned heater can have a certain axial length and the pumped fluid can travel a certain distance along it for heating.
  • the impeller is arranged above a front end surface of a cylinder shoulder projecting into the pump chamber.
  • This cylinder shoulder projects from an end of the pump remote from the pump chamber cover in the axial direction into the pump chamber and forms an inner wall of the pump chamber, in particular in a section in the axial direction following the impeller.
  • This shoulder is integrally connected to at least a part of the pump chamber outer wall, in particular it can form a pump chamber inner wall and then turn in a reverse region, so to speak, and form part of the pump chamber outer wall, in particular close to the outlet.
  • the heel may have a diameter similar to the diameter of the impeller, advantageously between 0.5 to 1.5 times the diameter of the impeller or its lower shroud.
  • the aforementioned rotor shaft, on which the impeller is seated and which is connected to the drive motor of the pump or forms part of it, may be guided by the aforementioned paragraph.
  • the heel may contain at least a portion of the drive motor of the pump.
  • a rotor of the drive motor seated on the rotor shaft can run therein.
  • a larger functional part of the drive motor in the paragraph run, preferably also radially within the outlet or radially within an outlet.
  • the drive motor can be arranged with its functional parts in the axial direction behind the outlet or outlet nozzle of the pump chamber.
  • the pump housing may be formed in three parts in the embodiment of the invention.
  • it may be formed by the pump chamber cover, a radially outer pump chamber wall, which is advantageously formed by an aforementioned heating means, and the aforementioned cylinder shoulder.
  • the cylinder shoulder can preferably be pulled up below the outlet and radially outwards and bent over in the direction of the inlet to reach the radially outer pump chamber wall. This rather complicated shape is easy to realize with a plastic injection molded part.
  • a stator is provided with at least one extending along the outside of the stator vane.
  • the guide vane is outwardly, advantageously approximately or substantially in the radial direction, and extends along at least part of the circumferential direction along the outside along. It has a pitch in comparison to a longitudinal axis through the rotor shaft, advantageously 5 ° to 30 °, particularly advantageously 8 ° to 20 °.
  • the guide vanes are preferably always equidistant from the outside of the stator or the lid. But this can also be varying.
  • a lid is placed, outside of the outside of the lid, the at least one vane is arranged or formed.
  • the cover has a bearing for the rotor shaft in the middle region.
  • the impeller may be located a short distance above the lid, for example at a distance of less than 5 mm.
  • the cover with the stator has a bearing support for a bearing of the rotor shaft.
  • This can advantageously be a bearing for a bearing bush for the rotor shaft.
  • the cover or the stator are formed decentrally to a longitudinal center axis through the rotor shaft or decentered to an outer wall of the pump chamber. Particularly advantageous they are as decentralized as the cylinder shoulder.
  • a conveying direction of the fluid conveyed in the pump can run within the pump housing or within the pump in such a way that it is monotonous in one direction or has at least one axial component that extends monotonously in one direction.
  • the fluid never runs counter to the inflow direction through the inlet into the pump chamber.
  • This conveying direction in the pump can even always a have axial component along the axial direction or parallel to the inflow direction, so run strictly monotonous. This should then apply until the pumped fluid leaves the pump chamber at the outlet.
  • the pumped fluid in the impeller also have an axial component of motion, which is always greater than zero.
  • the impeller is then a so-called Halbaxialimpeller or the pump is a Halbaxialpumpe.
  • the impeller may be designed as a pure radial impeller and thus the pump as a pure radial pump.
  • a pure radial impeller is more efficient.
  • the axial flow or axial component can be achieved in the purely radial design by the shape of the pump chamber lid and the displacement of the water in the continuous conveying process. This can then be achieved as good as possible conveying effect for the fluid in the pump.
  • Fig. 1 is an oblique view of a pump 11 is shown with a pump housing 12, which is one of the sectional views of the Flg. 2 and 3 better to see pump chamber 13 has.
  • the pump 11 has in a pump chamber cover 15 an inlet nozzle 16 and below an impeller 25.
  • an outlet 22 from the pump chamber 13 with an outlet 23 is provided in the general conveying direction F of the conveyed fluid.
  • This outlet 22 or outlet pipe 23 is arranged in the axial direction clearly far away from the pump chamber lid 15 and the inlet pipe 16. In particular, it is when the axial extent along in Fig. 3 Viewed in phantom longitudinal center axis of the pump 11, provided at the other axial end of the pump chamber 13 as the inlet port 16 and the impeller 25th
  • Fig. 1 is also the outside of a heater 18 with strip-shaped heating conductor 18 'shown, as it is known from the above EP 2150165 B1 is known. It can, so to speak, be exposed to the outside, alternatively, it can also be thermally insulated as a safety measure and to reduce waste heat from the pump 11 to the outside and to increase the heat efficiency of the pump.
  • a connector 19 for the pump 11 is provided in the vicinity of the outlet nozzle 23.
  • the pump chamber 13 is bounded by a circumferential inner wall 20.
  • This inner wall 20 is non-concentric and causes a varying in the direction of rotation of the pump chamber 13 width or varying cross-sectional area. This is for example from the German patent application DE 102012210554.9 with filing date of July 22, 2012 the same applicant.
  • the impeller 25 is arranged above a cover 27, which forms a kind of pump chamber bottom or at least its central region with respect to the pump chamber 13. At the same time, it closes the additional chamber 29 formed on the right side thereof within the pump chamber 13 as the aforementioned cylinder shoulder, which contains an additional fluid volume 30. To the right to the additional chamber 29 is closed and thus dense, forming a bearing 32b for a rotor shaft 35.
  • the bearing 32b or the bottom of the additional chamber 29 arranged on the right is designed as a type of bearing plate with a recess and a right bearing bush 33b therein.
  • a left bearing 32a is formed in the lid 27, in which a bearing bush 33a is held in the lid 27 or as a bearing 32a.
  • the bearing bush 33a forms a radial bearing for the rotor shaft 35.
  • an axial bearing ring 37 is still arranged or pressed against the rotor shaft 35. It rests with its left end face on the bearing bush 33a and also forms an axial bearing of the rotor shaft 35 to the left or in the direction of the inlet port 16.
  • a holding body 39 On the rotor shaft 35, a holding body 39 is fixed, which merges to the right in a rotor 40 of a drive motor 43 for the pump 11. Outside the auxiliary chamber 29, a stator 42 of the drive motor 43 is provided around the rotor 40.
  • an impeller 46 On the holding body 39 and thus on the rotor shaft 35, an impeller 46 is arranged with wings, as it is known for screws or propellers per se.
  • the same fluid is provided, which is funded by the pump 11.
  • the lid 27 has a plurality of passages 28. These cause the additional chamber 29 is filled with the fluid.
  • the impeller 46 should overall be designed so that it, as described above, at nominal operation of the pump 11 within the fluid volume 30 generates such a force along the dash-dotted longitudinal center axis of the pump 11 and along the rotor shaft 35 to the right, the corresponding force of the impeller 25, which is directed exactly opposite to the left. The remaining axial force to the left can be absorbed by the thrust bearing with bearing bushing 33a and thrust bearing ring 37.
  • Fig. 3 From the Fig. 3 is also good to see how the fluid along a fluid path F first passes through the inlet port 16 into the pump 11, and first in the impeller 25 into it. From this it is then applied with a predominant radial component, which is due to the shape of the impeller 25 can be seen that a, albeit small, but not negligible axial component is still given and that just in the previous axial direction. So it is a so-called Halbaxialimpeller or the pump 11 is a Halbaxialpumpe. Maintaining the axial movement component of the delivered fluid after discharge from the impeller 25 may be assisted by the shape of the pump chamber lid 15 on the inside in addition to the shape of the impeller 25.
  • the impeller may be designed as a pure radial impeller and thus the pump as a pure radial pump.
  • a pure radial impeller is expected to be more efficient.
  • the axial flow or axial component can be achieved in the purely radial design by the shape of the pump chamber lid and the displacement of the water in the continuous conveying process.
  • the pumped fluid overflows several times, for example, three times to eight times, but it moves steadily along the axial direction to the right, thus still has an axial component of movement.
  • the circulating and axially conveyed fluid enters the outlet 22 along the fluid path F and is brought out of the pump chamber 13 and the pump 11, respectively, from the outlet port 23.
  • the pumped fluid in the example shown no axial movement component more.
  • the outlet port 23 could also maintain this oblique direction.
  • the outlet 22 or the outlet connection 23 is arranged between the impeller 25 and at least one stator 42 of the drive motor 43 of the pump 11. Since the functional part of the rotor 40 of the drive motor 43 has approximately the axial extent of the stator 42, the outlet 22 and the outlet port 23 are arranged in the axial direction between the impeller 25 on the one hand and the functional part of the drive motor 43 on the other hand.
  • a pump 111 with a pump housing 112 has a structure similar to the pure pump function with a pump chamber 113 which is closed to the left by a pump chamber cover 115.
  • an inlet nozzle 116 is arranged or formed.
  • the pump chamber 113 is bounded by an annular heater 118 according to the first example.
  • An inner wall 120 bounds the pump chamber 113 radially inwardly.
  • the inlet port 116 leads exactly to an impeller 125 which is mounted on a rotor shaft 135 of a drive motor 143.
  • the rotor shaft 135 and the drive motor 143 are arranged on the dashed longitudinal center axis of the pump 111.
  • the drive motor 143 is shown purely schematically and protrudes further into the pump or extends until just before a bottom of the impeller 125th
  • the pump chamber 113 merges in the axial direction to the right into an outlet 122 with an outlet connection 123.
  • the outlet 122 or the outlet connection 123 is no longer arranged between the impeller and the drive motor, but rather at the axial height the drive motor 143 is located, approximately in the middle of this. Even so, a good construction and especially a compact design is achieved.
  • the drive motor 143 could even be considerably shorter in the axial direction, so that it barely protrudes, for example, out of the pump chamber 113 or out of the pump housing 112. Then, according to another general idea of the present disclosure, it would be possible for a drive motor of the pump to be located closer to the impeller in the axial direction, in particular with a substantial portion of its axial longitudinal extent, as an outlet or outlet port of the pump housing.
  • Fig. 5 is in a modification of the pump 111 from Fig. 4 represented here, wherein at the cylinder shoulder 121, which simultaneously forms the aforementioned inner wall 120, a separate cover 127 'is arranged on the left-facing free end, which covers or closes the cavity in the cylinder shoulder 121.
  • this cover 127 ' corresponds to the example of Fig. 3 apparent cover 27, only he is not now inserted into the front end side opening, but covers the entire cylinder shoulder 121 and is placed from the front. In it, the passages 128 'are formed.
  • vanes 145 are arranged, which protrude outwards or into the pump chamber 113.
  • the vanes 145 are integrally formed on the lid 127 '. However, they could also be placed outside in the manner of a ring.
  • there are four vanes 145 which extend in the circumferential direction each over a tight quarter circle and have a slope whose height is slightly less than the height of the lid 127 'in the axial length.
  • a different number of vanes is generally and advantageously possible, for example 2 to 6 or even 10.
  • the vanes 145 may be slightly curved away from the inlet 116 to provide the best possible effect to have the pumped fluid in the pumping chamber 113. But this need not be, they can also stand out at right angles or point in the opposite direction.
  • the vanes 145 each having the same distance from the heater 118 as an outer wall, for example 1 mm to 5 mm or even 10 mm under certain circumstances.
  • the lid 127 ' also has the bearing 132 a with the left bearing bushing 133 a, as already in the Fig. 4 the case is.
