The method also comprises steps for determining the predicted or resulting level of hygiene Hres of the laundry (7) taking into consideration a prespecified or determined initial level of hygiene Horig and / or the selected laundry treatment programme. The invention also relates to a laundry treatment appliance (1) which is suitable for carrying out this method.

Description

technical field [0001] The invention relates to a method for determining and displaying the hygiene level of laundry in a laundry treatment appliance and a laundry treatment appliance particularly suitable for the method. Background technique [0002] Recently, washing clothes at low temperature has gradually become a trend. Improvements in detergents and washing machines have made it possible to effectively remove stains even at low temperatures. Also, washing at low temperatures is increasingly required by the textile industry as many laundry items should only be washed at 30°C or 40°C according to the washing instructions. Washing at low temperatures also saves energy and thus protects the environment. However, many consumers are unsure whether a sufficiently high level of hygiene can be achieved through the low temperature washing process. Unlike stains, microbial bacteria are often invisible and a health hazard. If the washing machine is mainly operated in the low t...
