Embodiment Construction

[0027] The schematic diagram shows an air-cooled, therefore not water-cooled, dryer part 1 of a washer-dryer. The drying unit 1 comprises a condenser 2 with a hollow body 2 , in particular it is one heat exchanger tube 2 of a plurality of such heat exchanger tubes 2 in the condenser 2 . During the drying process, the condensed liquid 22 generated in the hollow body 2 flows from top to bottom on the inner surface 21 of the hollow body 2 . The process air P flows in the opposite direction to the flow direction of the condensed liquid 22 , so as to flow from bottom to top, wherein the flow direction of the process air P is determined by a fan (not shown) connected to the hollow body 2 . Externally, cooling air K passes through the hollow body 2 to remove heat from the process air P and to condense the accompanying steam. Since the inner face 21 is the coldest part of the hollow body 2, this condensation mainly takes place here. The means for driving and guiding the cooling air ...

Abstract

The invention relates to a domestic appliance for treating items of laundry with a dryer part (1) which can be cooled by cooling air (K) and comprises a condenser which comprises a hollow body (2) through which damp process air (P) which comprises lint can flow substantially upward from below and though which condensate liquid (22) can flow downward from above, wherein the hollow body (2) has a constriction (24) which is formed so as to prevent condensate liquid (22) running down the inner walls (21) of the hollow body (2) from running down in an unobstructed manner under the action of the process air (P) flowing in the opposite direction by approximately cylindric eddying (23), wherein a lint filter system is formed by means of the interaction between the eddying (23) and the flowing process air (P).

Description

technical field [0001] The invention relates to a household appliance, in particular a washing and drying machine, for treating laundry. Background technique [0002] A washing machine with a condenser configured for drying is known from EP 0 636 732 B1, said condenser essentially comprising a hollow body through which moist process air can flow from bottom to top and for cooling purposes the The hollow body is flushed with tap water via an on-off valve in the inlet. For water flow, the size of the inlet is selected to flush lint from the hollow body, and said inlet can be operated intermittently to supply cooling water. [0003] A washing machine with a condenser configured for drying is also known from DE 195 22 307 C2, said condenser essentially comprising a hollow body through which moist process air can flow from bottom to top and for cooling purposes the The hollow body is flushed with tap water via a switching valve in the inlet to the upper region of the hollow bod...
