Embodiment Construction

[0024] Exemplary embodiments of the present invention will now be described.

[0025] The household appliance to be described below is a tumble dryer comprising a drying chamber and a closed process air circuit within which the drying chamber is located and in which A heat pump is provided within the air circuit, wherein the heat pump has a heat sink and a heat source to alternately cool and heat the circulating process air. The two heat exchangers, operating as heat sink and heat source, respectively, are arranged as a labyrinth tube system of individual copper tubes and tube bends brazed together and mounted in vertically arranged fins. The fins are thin aluminum strips and serve to improve heat transfer between the working medium flowing within the tube system and the process air flowing around the tube system. In order to assemble the parts, conventional copper or silver solders are necessary for brazing copper parts as well as mountings, screws, etc. made of iron or bras...

Abstract

The invention relates to a home device for drying laundry, in particular a laundry dryer or a clothes dryer, said device comprising a component around which process air can flow, wherein the component comprises a metal or plastic substrate with a surface which faces the process air. This surface has a coating for preventing adhesion of foreign particles.

Description

technical field [0001] The invention relates to a household device (household appliance) for drying laundry, comprising a part around which process air can flow, said part having a metal base plate, wherein said metal base plate has a surface facing said process air. Background technique [0002] Domestic appliances of this type arranged as tumble dryers for drying laundry are disclosed in patent publications WO 2007 / 093461A1, WO 2007 / 093467A1 and WO 2007 / 093468A1, respectively. The appliances are respectively set up as tumble dryers for drying wet laundry. The appliance comprises a drying chamber arranged as a rotating drum for containing wet laundry; and a treatment air circuit, wherein the drying chamber is located within the treatment air circuit and a flow of treatment air circulates within the treatment air circuit. Before entering the treatment chamber, the treatment air is heated by a heat source so that it can absorb moisture from the laundry being swirled within t...
