Embodiment Construction

[0031] 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 sanitizing a temperature-sensitive item of clothing (1) comprises the steps of: in a dry state, the item of laundry is exposed to a stream of treatment air (14) having a defined temperature Tp for a specified period of time, The laundry item ( 1 ) heated in this way is then cooled to a target temperature Tptarget which is significantly lower than the temperature Tp, and the cooled laundry item ( 1 ) is then washed in a washing process. The washing-drying unit according to the invention has a control device (CTRL) for carrying out the method.

Description

technical field [0001] The present invention relates to a method for sanitizing temperature-sensitive items of clothing, the method being characterized in that the item of laundry is exposed in the dry state to a flow of treatment air at a defined temperature for a specified period of time without water and heated, the item of clothing heated in this way is then cooled to a target temperature significantly lower than said defined temperature. The invention also relates to a washing-drying unit. Background technique [0002] A method of this type and a drying and sanitizing cabinet for carrying out the method are known from EP0262451A2. According to the document, laundry items are sanitized immediately after being dried. [0003] US2007 / 0169282A1 and JP4-158896A relate respectively to a method and a washing machine for carrying out the method, wherein the laundry items to be washed are first treated by steam in order to sanitize and moisten said laundry items or to relax th...
