摘要:
A new and useful dryer (11) has a control (35) with which sensors (22, 23) in a drum (13) of the dryer are connected via a contact path. An AC measuring signal is applied to the sensors via the contact path for determining the conductivity of wet laundry and as such the moisture of the laundry in the drum. By employing AC measuring signal, electrolyte erosion as well as passivation of contacts and sensors is avoided.
摘要:
With the invention it is possible to define the functionalities of an electrical appliance, for example a washing machine (11), in a simple and comfortable way. Control means (13) of the appliance (11) are connected to an AC main cable (20) of the appliance. The AC main cable (20) is connected to a setup and test device (25). The setup and test device (25) provides information for defining the functionality and the machine setup via the AC main cable (20) to the appliance (11). The information can be frequency modulated onto the main voltage or otherwise be transmitted before powering the appliance.
