Embodiment Construction

[0019]The pump housing part 1 shown in FIGS. 1 and 2 is a cap. The housing part 1 has a base body made of stainless steel 2 forming a connecting tube 3. The pump housing part 1 can be heated with a U- or C-shaped tubular heating element 4, which is soldered onto a heat distribution sheet 5 that spreads over a cover surface of the housing part and is soldered with it.

[0020]As shown in the sectional view of FIG. 2, the heat distribution sheet 5 covers a U- or C-shaped groove in the housing part. The groove can have an angular cross-section, particularly rectangular or trapezoidal, or a U-shaped cross-section. The tubular heating element 4 is arranged in this groove, such that it touches both the side walls of the groove. On both the sides, the heat distribution sheet 5 projects by more than 0.5 cm beyond the side walls of the groove. An advantage of this is that a larger area of contact is created between the tubular heating element 4 and the heat distribution sheet 5. It is preferred...

Abstract

The description relates to a heatable pump housing part comprising a heat distribution sheet fixed on the housing part and a tubular heating element fixed on the heat distribution sheet. According to the invention the tubular heating element is positioned in a groove or a step on the housing part that is covered by the heat distribution sheet.

Description

[0001]This invention refers to a heatable part of a pump housing on which a heat distribution sheet is fixed on which a tubular heating element is arranged. Such a pump housing part is known from DE 199 03 951 A1. Heatable pump housing parts are, for example, required for washing machines or dishwashers.[0002]The pump housing known from DE 199 03 951 A1 has an aluminium heat distribution sheet fixed on a flat or conical cover surface. The heat distribution sheet distributes the heat generated from a tubular heating element, which is soldered onto the plate, quickly over a large area and transmits it to the stainless steel housing part situated below it.[0003]Furthermore, EP 1 507 914 B1 discloses another pump housing part. A tubular heating element is arranged in a suitably shaped groove of the housing part. To facilitate a good heat coupling between the tubular heating element and the housing part, joints and any free spaces between the tubular heating element and the walls and bot...
