Abstract

В бытовом приборе 1 для сушки белья 3 необходимо с особой достоверностью измерять моментальную степень сухости белья 3. Бытовой прибор 1 оснащается измерительным устройством 5, предназначенным для определения измеряемого параметра 4, U, коррелированного со степенью сухости белья 3. Измерительное устройство 5 содержит два измерительных электрода 6, 7, расположенных на некотором расстоянии друг от друга, и схемное устройство 8, соединенное с измерительными электродами 6, 7 и выполненное таким образом, чтобы оно могло воздействовать на ток I, протекающий через измерительные электроды 6, 7, измерять падение электрического напряжения Uна белье между измерительными электродами 6, 7 и определять измеряемый параметр 4, Uв зависимости от измеренного напряжения Uна белье. Направление тока I, протекающего через измерительные электроды 6, 7, циклично изменяется. Таким образом, предотвращается возникновение гальванических эффектов на измерительных электродах 6, 7.In a household appliance 1 for drying laundry 3, it is necessary to measure with particular accuracy the instantaneous degree of dryness of the laundry 3. The household appliance 1 is equipped with a measuring device 5 designed to determine the measured parameter 4, U, correlated with the degree of dryness of the laundry 3. The measuring device 5 contains two measuring electrodes 6, 7 located at a certain distance from each other, and a circuit device 8 connected to the measuring electrodes 6, 7 and made so that it can act on the current I, prote bending through the measuring electrodes 6, 7, measure the voltage drop U on the laundry between the measuring electrodes 6, 7 and determine the measured parameter 4, U depending on the measured voltage U on the linen. The direction of the current I flowing through the measuring electrodes 6, 7 changes cyclically. Thus, the occurrence of galvanic effects on the measuring electrodes 6, 7 is prevented.
