Definitions
- the invention relates to a household machine, in particular a washing machine, a dishwasher or the like according to the preamble of claim 1.
- a water pump is known from the publication DE 201 07 363 U1, in which a heating element is inserted on the circumference into a circumferential bead.
- a liquid pump for a dishwasher has also become known, in which a heating element is also integrated.
- the heating element is attached on the outside or on the inside to a pump housing that is closed with the exception of connecting pieces.
- the on and for the production and assembly is already significantly reduced in this above-described version compared to the older prior art.
- the object of the invention is to propose a household machine with a liquid pump with outside heating, in which the efficiency of the heating is improved.
- the heating element is at least partially positively adapted to the external shape of the pump housing with a heat-conducting or heat-transferring contact surface, so that the contact surface is at least half as large as the entire outer surface of the heating element.
- the outer shape is preferably provided with a structure that enlarges the contact area. Measures can be considered, such as a structure with an angled or corrugated cross-section.
- the efficiency can be further increased by keeping the so-called dead volume V t of the pump, ie the volume of the liquid in the pump (or the total volume of the pump housing minus the volume of the pump wheel) small in relation to the maximum total delivery rate.
- a ratio of the dead volume to the maximum total delivery rate V G is preferably selected as follows: V ⁇ / v G ⁇ 0.2, preferably ⁇ 0.15 or ⁇ 0.1, with V [cm 3 ] and v G [cm 3 / sec ].
- the pump housing of the liquid pump is provided with an outer recess into which the heating element is inserted.
- the contact area between the corresponding housing part and the heating element is increased, which further increases the efficiency.
- the heating element is integrated into the pump housing from the outside, so that there are no sealing or insulation problems with the heating element.
- the outer recess is formed in such a way that a projection forms on the inside of the pump housing. This increases the contact area of the housing with the liquid in the heated area. This measure thus results in a further increase in efficiency.
- the inner projection is preferably aligned along the flow direction in order to disturb this pumping action as little as possible.
- the dead volume of the pump is reduced by the inner projection, while its alignment, as mentioned above, has little effect on the total delivery rate.
- the outer recess is also chosen to be deeper than the corresponding dimension of the heating element, so that the housing protrudes with a protrusion over the heating element inserted into the recess. In this way, the contact area is increased and the heat loss to the outside is reduced, ie the proportion of heat that enters the liquid inside the pump housing through the housing wall increases. This measure also serves to improve the efficiency of the heating.
- the heating element is pressed onto the housing, for example in the depression. Such pressing causes a particularly close and flat contact between the heating element and the corresponding housing part and accordingly serves to improve the heat flow from the heating element into the interior of the housing.
- a thermally conductive filler is provided between the heating element and the housing wall.
- a filler can also improve thermal contact. This is particularly true where the outer shape of the heating element differs from the shape of the pump housing. Such deviations can hardly be avoided within the framework of normal error tolerances. With the help of a thermally conductive filler, good thermal contact can nevertheless be ensured.
- the filler can, for example, be introduced into the recess before the heating element is inserted, so that it is partially displaced again when the heating element is pressed in and, if possible, completely fills up any space between the heating element and the housing wall.
- such a filler is also provided for fastening the heating element.
- the filler can be formed, for example, as an adhesive or as a solder, by means of which the heating element is firmly fixed in the housing recess.
- the outer shape or the structure of the heating element is preferably designed such that there is an enlarged contact area with the corresponding section of the housing wall and thus with the pump interior.
- the heating element is designed as a ring segment.
- a ring segment is particularly advantageous in the case of a cylindrical pump housing.
- the corresponding housing part can be designed as an end cover for the pump housing, which simplifies manufacture and assembly.
- the desired contact area can be determined by the design of the cross section of the heating element, e.g. in a triangular, rectangular, square or trapezoidal shape. These cross-sectional shapes allow a large-area form fit.
- the housing recess does not or only slightly behind the heating element, so that the heating element can be inserted into the recess without major deformation of the housing.
- a slight engagement behind to form a snap connection can be advantageous. It is essential here that the heating element can be inserted after prior separate shaping of the housing.
- the cross section can have corrugated or zigzag structures.
- the contact area is made larger than half of the surface of the heating element specified as the minimum size. The efficiency can be further improved if the contact area is greater than 60%, 70%, 80% or even 90% of the total surface of the heating element.
- the pump housing is advantageously formed in two parts, the heating element being attached to a housing part.
- the shape of the depression according to the invention is easier to achieve, and on the other hand, a material different from the rest of the pump housing can be selected for the housing part which carries the heater.
- a metal can be used for this housing part, which combines good thermal conductivity with high temperature resistance.
- Such a housing part can e.g. Manufacture inexpensively in large quantities from a flat material by compression molding or deep drawing.
- a suitable plastic can be used for the rest of the housing, which can be processed, for example, by injection molding.
- the pump is designed as a centrifugal pump with an axial inflow and tangential outflow.
- a centrifugal pump offers good efficiency with regard to the pumping action and can easily be provided with a heating element integrated according to the invention.
- the drive shaft for the pump wheel must be led out of the housing in a liquid-tight manner and on the other hand the axial inflow is usually provided on the side opposite the drive.
- the heater according to the invention can in principle be arranged both on the side of the axial inflow and on the drive side.
- the version with the heating element on the inflow side offers advantages in terms of production technology and design.
- the dimensions of the drive do not have to be matched to the heating element.
- an inflow for example in the form of a connecting piece, a collar or a flange, can easily be molded into the housing part carrying the heater by means of the same shaping method, with which the depression according to the invention is also applied.
- the housing of a centrifugal pump with a heater attached according to the invention can be cylindrical or also helical, as is often the case with centrifugal pumps.
- FIG. 1 shows a plan view of a housing part for a pump with a heating element integrated according to the invention
- Figure 2 is a side view of a
- FIG. 3 shows an enlarged detail of the housing part according to FIG. 1 in section
- FIG. 4 is a sectional view of a complete pump.
- the housing part 1 according to FIG. 1 is designed as a cover for a further housing part of a centrifugal pump containing the pump wheel. It has an outer recess in the form of an annular groove 2, into which a heating element 3 which is bent from a rod-shaped blank to form an annular segment is inserted.
- An inflow opening 4 is provided centrally for the axial inflow of the centrifugal pump.
- the connections 5, 6, which are attached on both sides at the end of the heating element 3, are bent out of the ring plane of the heating element 3, so that they protrude from the ring groove 2 and are therefore easily accessible.
- the protruding connections 5, 6 are clearly visible in the drawing view according to FIG. 2.
- a collar 7 for connecting an inflow line is molded into the housing part 1 around the inflow opening 4.
- the annular groove 2 is formed in a flat material in such a way that a projection 8 results on the inside.
- this offers advantages in terms of production technology, in that the housing part 1 can be produced from a flat material, on the other hand, the projection 8 results in an increase in the contact area on the inside of the pump housing formed with the aid of the housing part 1.
- Both the base 9 and the side walls 10, 11 of the projection 8 are washed around by the liquid in the interior of the pump to be formed with the housing part 1 and accordingly serve as an inner heating surface.
- the formation of the annular groove as an inner projection 8 thus almost triples the contact area compared to a heating element placed on a flat housing part.
- the heating element 3 and the annular groove 2 are adapted to one another in their cross-sectional shape, so that the heating element 3 lies in the annular groove 2 in a form-fitting manner. This results in large contact areas between the housing part 1 on the one hand and the heating element 3 on the other hand, these contact areas being joined flat to one another.
- a filler material (not shown in detail) can also be provided in order to fill up smaller gaps between the heating element 3 and the housing part 1 in the annular groove 2 and thus to ensure good heat transfer even at such points.
- the annular groove 2 is formed deeper than the corresponding height h of the heating element 3, so that the housing part 1 projects beyond the heating element 3 with a projection a.
- the heating element 3 is, as it were, immersed in the annular groove 2. This reduces the amount of heat given off to the outside.
- the side walls 10, 11, which are available for heat transfer to the liquid, are enlarged by the projection a.
- connection of the housing part 1, which is preferably made of heat-conducting and temperature-resistant material, for example Metal, is made with at least one further housing part can be carried out in a variety of ways.
- a releasable connection such as a snap-in or snap connection, can optionally be provided with appropriate sealing elements.
- a fixed connection to the further housing part is also conceivable, for example by gluing, soldering or welding.
- FIG. 4 shows a complete pump 12 with drive motor 13 and heating element 3 according to the invention.
- the housing part 1 described above serves as a cover for another housing part 14.
- the housing part 14 is penetrated by the drive shaft 15 of the drive motor 13.
- the passage of the drive shaft 15 is sealed in a manner not shown.
- a pump wheel 16 is fastened to the drive shaft 15.
- the inflow takes place via the inflow opening.
- the outflow takes place tangentially into an outflow connection 17, where the flow is deflected parallel to the inflow.
- the housing part 1 is firmly connected to the housing part 14.
- the metal housing part 1 is overmolded in the edge region 18 during the manufacture of the other housing part 14 made of plastic.
- detachable variants are also conceivable, which may be additionally sealed.
- the heating element is inserted into an outer recess in the pump housing.
- the housing part 1 accordingly closes the pump housing to be sealed. There are no sealing and / or insulation problems in relation to the heating element 2 or its electrical connections 5, 6.
- the manufacture of a housing part 1 with a heating element 3 inserted according to the invention is particularly simple and therefore inexpensive.
