Method for detecting a submerged or emerged operating condition of an electric resistance used in a washing machine

摘要

The present invention relates to a method for detecting a submerged or emerged operating condition of an electric resistance used in a washing machine. In the first step of the method, the electric resistance is turned on for a first time interval. In the second step of the method, the electric resistance is turned off. In the third step of the method, the temperature detected by a temperature sensor in a condition of thermal exchange by conduction with the resistance is measured, so that water is supplied into the tub when the temperature reaches or exceeds a predetermined threshold value.
