Embodiment Construction

[0029] In this method, the laundry to be washed, ie the laundry items to be washed, is heated by means of a flow of process air while still in a dry state, ie before the actual washing process starts. The heating is carried out to a defined temperature Tp, which is specified in a fixed manner or can be preselected by the device performing the heating. Here, said defined temperature Tp is advantageously pre-selected to fall within the range of 60°C-120°C, especially 70°C-90°C inclusive. Once a defined temperature Tp is reached, the laundry is exposed to this temperature for a predetermined time period T, wherein the specified time period T is in the range of five to twenty-five minutes, especially in the range of ten to twenty minutes (including endpoints). Said time period T is specified in a fixed manner or is preselected by the means for heating. The heating in the stream of hot air performs the desired disinfection, in particular almost completely kills the microorganisms...

Abstract

The method according to the invention for sterilizing temperature-sensitive laundry items (1) comprises the following steps: in the dry state, the laundry items are exposed to a process air flow (14) having a defined temperature Tp and over a specified time period, then the laundry items (1) heated in such a way are cooled to a target temperature Tptarget significantly lower than the temperature Tp, and then the cooled laundry items (1) are washed in a washing process. The washing-drying unit according to the invention has a control device (CTRL) for carrying out said method.

Description

technical field [0001] The invention relates to a method for disinfecting laundry and a washing-drying unit. Background technique [0002] It is well known that delicate garments should only be washed at low temperatures (e.g. room temperature or in the range of 30°C-40°C), as at higher wash temperatures the fabric or coloring of the garment will be adversely affected, at least after many washes will be damaged after the process. This will cause fabric discoloration or color transfer from one fabric to another. However, a disadvantage of washing at low temperatures is that microorganisms in the laundry are not killed to the same extent by such low temperature washing as compared to washing at a higher temperature, eg 95°C ("boiling wash"). This disadvantage is conventionally avoided by exposing the still damp laundry after the washing process to hot air by means of a laundry drying device. [0003] This possibility is also disclosed in DE 10 2005 052 960 A1. However, del...
