Washing machine, in particular a laundry machine or washing/drying machine or a dishwasher, equipped with a device for detecting the temperature of the electric resistance used for warming up the wash liquid

摘要

The present invention relates to a washing machine (2), in particular a laundry washing or washing/drying machine or a dishwasher, comprising: a tub (3) adapted to contain a wash liquid (4), an electric resistance (1) for heating the wash liquid (4), a temperature sensor (5) for detecting the temperature of the wash liquid (4), wherein the resistance (1) and the temperature sensor (5) are put in a condition of thermal exchange by conduction. The invention also relates to a method for evaluating whether the resistance is emerged from or submerged in the wash liquid and to a method for removing calcareous deposits (17) from an electric resistance (1) adapted to heat a wash liquid (4) in a washing machine (2), in particular a laundry washing or washing/drying machine or a dishwasher, characterized in that the resistance (1) is subjected to at least one heating and cooling cycle while the resistance (1) is kept above the wash liquid (4).

主权项

1. A washing machine, in particular a laundry washing or washing/drying machine or a dishwasher, comprising:
a tub adapted to contain a wash liquid, an electric resistance for heating the wash liquid, and a temperature sensor positioned for detecting a temperature of the wash liquid, the temperature sensor being further coupled to a first end of the electric resistance and being in a condition of thermal exchange by conduction with the electric resistance for detecting a resistance temperature of the electric resistance,
the first end of the electrical resistance being coupled to a wall of the tub and a second end of the electrical resistance being free and not coupled to the tub, andthe electric resistance being positioned at an angle within the tub so that the first end of the electric resistance is at a higher position, with respect to the bottom of the tub, than that of the second end of the electric resistance.
