Description

Heatable pump housing part
Technical Field
The invention relates to a heatable pump housing part.
Background
The pump housing part known from DE 102009052019 a1 is produced from a cut steel plate into which an annular tongue-and-groove or an annular recess is formed. A trapezoidal line heating element is fixedly welded in the groove or on the recess. In this way, a comparatively good thermal connection and a reliable positioning of the line heating element can be combined during production.
Furthermore, EP 1507914B 1 discloses a heatable pump housing part, in which a line heating element with a rectangular cross section is arranged in a recess of the housing, which recess is formed in a suitable manner. In order to bring about a good thermal connection of the line heater to the housing, the joints and any gaps between the line heater and the wall or bottom of the groove are filled with a thermally conductive filler. Examples of such fillers are adhesives or fluxes.
The object of developing a heatable pump housing part for a washing machine or dishwasher is to achieve as good and reliable a thermal connection of the line heating element to the pump housing part as possible with as little effort as possible. The better the thermal connection, the more quickly the heat generated by the line heating element can be released to the pump housing part and from there to the fluid flowing through the pump housing part. Furthermore, the further the operating temperature of the line heater can be reduced, the better the thermal connection. The lower operating temperature of the line heater makes it possible to reduce the play between the line heater and other components in the washing machine or dishwasher, in particular to use more cost-effective plastics around the line heater, since these plastics have to withstand the high temperatures to a lesser extent.
The reliability of the joint is at least as important as a good thermal connection of the line heating element. In other words, the deterioration of the thermal connection occurring during operation results in the heat produced by the line heater no longer being able to be dissipated so well, and the line heater is therefore overheated.
Disclosure of Invention
The object of the invention is to specify a way of improving the thermal connection of a line heater to a pump housing even further with the least possible effort.
In the pump housing part according to the invention, the curved line heating element is thermally conductively joined to the housing part. The line heating element is inclined radially outward from the upper side to a radially inward longitudinal edge of the lower side connected to the housing element. Thus, in other words, the radially inner edge of the upper side is radially inward from the radially inner edge of the lower side. Wherein the expression "radial" relates to the radius of the curved line heating element. The radially outer longitudinal edge of the line heating element extends perpendicularly to the lower side or is likewise inclined radially outward from the upper side toward the lower side connected to the housing element. In this way, a greater part of the circumference of the line heating element can be brought into contact with the housing part, thereby improving the thermal connection. It is particularly advantageous here if the radially inner longitudinal edge of the line heating element is joined to the housing in a heat-conducting manner, like the underside, so that good thermal contact can be made, while the radially outer longitudinal edge can preferably be spaced from the housing part. In this way, the heat input in the radially outer edge region of the housing part can be reduced, thereby reducing the thermal load on the sealing arrangement arranged there. In addition, thermal-dependent length changes and the resulting mechanical stresses may be less likely to cause the line heating element to detach from the housing member. In an advantageous embodiment, the housing part is a metal part, for example a formed steel plate made of stainless steel. Other designs are equally contemplated. In particular, the thermally conductive connection can be produced by welding, since a good, reliable heat conduction is to be ensured here. Other thermal connections are likewise conceivable, such as, for example, gluing, pressing or stitching.
An advantageous development of the invention provides that the two housing parts surfaces, which are thermally connected at least in sections to the underside and the radially inner longitudinal edge of the line heating element, enclose an angle α of 100 ° to 160 ° between them. Preferably, the angle is 105 ° to 145 °, particularly preferably 110 ° to 130 °. Angles in this range enable both economical manufacture and advantageously large contact areas.
A further advantageous development of the invention provides that the sections of the longitudinal edges adjoining the upper side run substantially parallel to one another. Where "contiguous" is to be understood such that the transition radii that may exist in the corner regions remain negligible. Wherein the longitudinal edges may extend substantially parallel to each other over their entire width. Preferably, however, the section of the radially outer longitudinal edge adjoining the upper side extends parallel to the radially inner longitudinal edge. For example, a section of the radially outer longitudinal edge, which section extends in a straight line in cross section and is parallel to the radially inner longitudinal edge, adjoins the corner between the upper side and the radially outer longitudinal edge. Then, a section which extends more steeply or even perpendicularly to the underside adjoins this upper section of the radially outer longitudinal edge. The radially outer longitudinal edge can therefore preferably be reduced with little manufacturing effort, so that the heat input into the radially outer edge region of the housing part, which is problematic with regard to sealing, is reduced.
A further advantageous development of the invention provides that, at least in the section adjoining the underside, the radially outer longitudinal edge of the line heater rises more steeply than the radially inner longitudinal edge. In this way, it is achieved that less heat is generated in the radially outer edge region of the housing part, so that the sealing arrangement arranged there is less loaded.
A further advantageous development of the invention provides that the upper side of the line heater has a projection for fastening a carrier for the temperature-sensitive circuit element. Such a heat-sensitive circuit element can be, for example, a temperature controller or a thermal fuse. The carriers of these temperature-sensitive circuit components are usually soldered onto the upper side of the heating element of the line. The heat-sensitive circuit element can advantageously be fixed to the upper side of the line heating element by means of the bead during the soldering process. The bulge is preferably formed by a jacket of the line heating element.
In a further advantageous development of the invention, the pump housing part has an opening in its center for connecting a fluid line. Such a pump housing part is sometimes also referred to as a cover of the pump housing.

Detailed Description
The pump housing part shown in fig. 1 is formed from a sheet steel 1 to which a line heating part 2 is welded. The pump housing part can be, for example, a cover which is formed from cut steel and has openings 3 for the fluid lines to be connected.
The curved line heating element 2 is arranged in the embodiment shown in an annular groove. Instead of an annular tongue-and-groove, a C-shaped tongue-and-groove can also be provided, i.e. a curved tongue-and-groove which does not form any complete ring. At its end, the C-groove can have a straight section or can also be curved there.
As is shown in particular in fig. 3 to 5, the line heater 2 has an upper side, a lower side and longitudinal edges connecting the upper side to the lower side. The radially inner longitudinal edge and the underside are welded to the metal sheet 1 and are thus in good thermal contact with the metal sheet 1. On the other hand, the radially outer longitudinal edge is not in contact with the metal sheet 1. Between the radially outer wall of the annular groove and the radially outer longitudinal edge of the line heating element 2 is an air gap in order to reduce the heat input into the radially outer edge region of the pump housing element and to limit the temperature load of the sealing device 8 arranged there.
The radially outer wall of the groove is therefore not necessary thermally. Instead of being arranged in a tongue-and-groove, the line heater 2 can therefore also be arranged on a ring-shaped or C-shaped recess of the metal sheet 1. But a tongue-and-groove has the advantage over a recess of mechanically reinforcing the pump housing parts and is therefore preferred.
The radially inner longitudinal edge of the line heating element 2 extends from the upper side radially outwards towards the lower side. Thus, the longitudinal sides are inclined radially outwardly from the upper side toward the lower side. Thus, the radially inner edge of the upper side is arranged radially inwardly from the radially inner edge of the lower side. The two sheet metal surfaces which are welded at least partially to the underside and the radially inner longitudinal edges of the line heating element 2 define an angle β which is not indicated in fig. 5. In fig. 5, the angle α is indicated for this purpose. The relationship β is 180 ° - α for both angles. The angle is between 100 ° and 160 °, preferably between 105 ° and 145 °, particularly preferably between 110 ° and 130 °. In this way, the heat produced by the line heating element 2 is well conducted through a relatively large contact area with the metal sheet 1.
The radially inner longitudinal edge has the same line shape in a radial sectional view as the underside, in particular a straight section. The radially inner longitudinal edge can be tapered, for example. The radially outer longitudinal edge can be shaped like the radially inner longitudinal edge, i.e. inclined radially outward from the upper side to the lower side, in particular parallel to the radially inner longitudinal edge. The radially outer longitudinal edges preferably have another configuration than the radially inner longitudinal edges. The radially outer longitudinal edge can extend, for example, perpendicularly to the underside. In the exemplary embodiment shown, the radially outer longitudinal edge has a portion adjoining the lower side, perpendicular thereto, and a portion adjoining the upper side, which portion slopes radially outward from the upper side toward the lower side. This section adjoining the upper side is preferably parallel to the radially inner longitudinal edge.
As is shown in particular in fig. 5, the underside of the line heater 2 can have a greater width than the longitudinal sides. The upper side of the line heating element 2 is substantially flat and parallel to the lower side, but can also be designed, for example, to be arched or inclined to the lower side. On the upper side of the line heating element 2 is a projection 5 for fixing a carrier 6 of a temperature-sensitive circuit element 7, for example a temperature fuse or a temperature controller. The bulge 5 is formed by the jacket of the pipeline heating element 2 and is embedded in an adaptation hollow of the relevant carrier 6. The elevation 5 can be in particular a fixing carrier 6, which is welded to the line heating element 2.
Fig. 7 shows a further exemplary embodiment of a line heating element 2 for a pump housing part. While the elevation 5 for fastening the carrier plate 6 is provided in the line heater 2 shown in fig. 1, the line heater 2 shown in fig. 7 has a depression 13. As shown in fig. 8, a carrier, for example a carrier plate, is embedded in these recesses 13. In this way, the carriers 6a, 6b can be positioned on the line heating element 2 during welding.
