Household appliance i.e. exhaust air dryer, drying process controlling method, involves reducing limit temperature to limit value after fulfillment of preset error criterion related to gradients, and continuing drying process with value
The method involves conveying a supply air flow by a blower (5) via a supply air channel (6), where temperature of the supply air flow is periodically detected in the channel. A limit temperature is adjusted to a limit value, and a supply air heater (7) is disconnected for a preset time interval, if the temperature of the air flow exceeds the limit temperature. The limit temperature is reduced to another limit value after fulfillment of a pre-determined error criterion related to difference and/or gradients. A drying process is continued with the latter limit value. An independent claim is also included for a household appliance.
