Definitions

  • the present invention relates to a household appliance wherein the temperature of the heated water can be measured accurately.
  • an NTC sensor Negative Thermal Coefficient
  • a voltage divider circuit the resistance of which changes, decreasing with temperature and the resistance change can be detected by means of a voltage divider circuit.
  • the object of the present invention is to design a household appliance wherein the temperature of the liquids utilized during operation can be measured accurately and inexpensively without being in contact with the heated liquid.
  • the household appliance comprises a heater that heats the liquids within, a control card, connected to the heater and feeds the heater, having a measurement circuit with a resistor. Measurement the temperature of the water used in the household appliances is maintained by monitoring the current that passes over the heater that heats the water. The resistance of the heater changes with respect to the temperature of the water heated. Accordingly, the current drawn by the heater changes and the current drawn by the resistor in the circuit that feeds the heater also changes together with the heater. The temperature of the water can easily be determined by the control card that monitors this change. Consequently, the temperature of the water can be determined without putting in an extra sensor in the chamber containing the liquid.
  • Rgure 1 - is the schematic view of a household appliance.
  • Rgure 2 - is the schematic view of a measurement circuit.
  • the household appliance (1) comprises a chamber (5) wherein the liquid is contained, a heater (2) situated in the chamber (5) providing the heating of the liquid in the chamber (5), the resistance value of which changes with respect to the liquid it is situated in, and a control card (3) that regulates the operation thereof.
  • the control card (3) comprises a measurement circuit (4) situated outside the chamber (5), providing to determine the temperature of the heated liquid.
  • the measurement circuit (4) comprises a resistor (6) connected parallel to the line coming from the heater (2) that does not contact the liquid in the chamber (5).
  • the control card (3) constantly monitors the current on the resistor (6) with the help of the measurement circuit (4) for safety and control purposes, providing to correlate the current change with the temperature variation values predetermined by the producer with experimental data and to determine the liquid temperature by e.g. a micro controller (M).
  • M micro controller
  • the resistor (6) acts as a means for measuring the temperature of water.
  • a resistor (6) of high sensitivity with low value (10 mW,, 20 mW,, etc) is utilized.
  • the heater (2) is used in heating the water necessary for washing the laundry and the washing water temperature in all phases of washing is determined by monitoring the current change of the resistor (6) connected to the heater (2).
  • the control card (3) determines how much the heater (2) has to operate according to the determined temperature and the heater (2) is energized and/or de-energized at the required time for as long as required in the required washing phases. Consequently while heating is done by the heater (2) also the temperature of the washing water is measured sensitively and safely without using any extra sensors.
