Definitions

  • the present invention relates to washing machines wherein water
  • a washing program is implemented that consists of various steps such as pre-washing, main washing and rinsing.
  • the washing and/or drying performance is inversely proportional to the hardness degree of water.
  • the hardness of water results from the positive calcium and magnesium ions (Ca++ and Mg++) dissolved therein.
  • the softening unit having an ion exchanger is used in order to decrease the hardness of water.
  • the water used in washing is first passed over the ion exchanger, for example, resin.
  • the ion exchanger absorbs these ions from the water and gives off sodium ions (Na+) instead. Consequently, the hardness of water is decreased.
  • the ion exchanger becomes unable to absorb the calcium and magnesium ions. Therefore, the calcium and magnesium ions are provided to be removed and to be enriched with sodium ions again by keeping the ion exchanger in a salt solution (for example NaCI) or by the capacitive deionization method. This process is called regeneration. It is important to make the regeneration process properly so that the ion exchanger can soften the water. Sensors are used in the technique for performing the regeneration process in the correct frequency.
  • the washer comprises an electrical conductivity sensor which measures the electrical conductivity of water both before and after water is passed through the ion exchanger.
  • the decision for regeneration is given by registering and comparing the difference with previous values of conductivity from earlier treatment cycles detected by the two sensors. If the said difference is below a certain threshold value then it is understood that the ion exchanger is not functioning properly and regeneration is performed.
  • the explained washer comprises a conductivity sensor that measures the conductivity of the ion exchanger. When to perform the regeneration process is determined in accordance with the measured value.
  • the aim of the present invention is the realization of a washing machine wherein effective washing is performed even in the case the water softening process cannot be performed.
  • the water softening unit providing to decrease hardness of water, comprises an ion exchanger, a regeneration unit and a sensor that detects whether or not the regeneration unit is functioning. Work data of the water softening unit is transmitted to the control unit that regulates the washing program.
  • control unit When the control unit detects an error in the regeneration unit or in the sensor during the washing performed with the parameters selected by the user, the control unit readjusts the washing parameters so that decrease in the washing effectiveness is prevented.
  • the water temperature selected by the user is increased by the control unit so that the laundry is cleaned effectively which is washed with un-softened water resulting from the softening unit not functioning due to depletion of ions providing
  • the control unit prolongs the duration of the washing process by readjusting the program duration selected by the user. Consequently, even though the water cannot be softened due to the occurring error, the cleaning performance is prevented from decreasing by performing the washing for a longer period of time.
  • the drum rotates at a
  • control unit increases the decreased washing effectiveness resulting from water not being softened by increasing the rotation speed by a predetermined amount.
  • the control unit prolongs the rotation duration and shortens the stopping duration of the drum which rotates for a certain time and stops for a certain time under normal conditions.
  • control unit continues the washing process with the changed parameters however delivers a warning to the user when the softening unit is detected not to function properly.
  • control unit changes the washing parameters thus preventing the washing
  • Figure 1 - is the schematic view of a washing machine.
  • the washing machine (1 ) provides cleaning of the laundry in accordance with a washing program that includes at least some of the various steps like pre-washing, main washing, rinsing, and spin-drying.
  • the washing programs are performed in accordance with the parameters like washing temperature and washing duration selected by the user.
  • the washing machine (1 ) comprises a drum (2) wherein the laundry to be washed is placed, a softening unit (3) having an ion exchanger (4) providing the water to be delivered to the drum (2) to be softened, a regeneration unit (5) that provides regeneration process of the ions to be performed when the ions in the ion exchanger (4) are decreased, and a sensor (6) that detects when the ion exchanger (4) becomes unable to absorb the ions contained in the water passing therethrough ( Figure 1 ).
  • the calcium and magnesium ions are provided to be separated from the ions supplied by the regeneration unit (5) and to be enriched with the sodium ions again. This process is called regeneration.
  • the washing machine (1 ) comprises a control unit (7) that actuates the regeneration process in accordance with the data received from the sensor (6). Under normal work conditions, the sensor (6), delivers data to the control unit (7) at the start of each washing process about whether or not the regeneration process will be performed.
  • the control unit (7) prolongs the washing duration (t1) determined while the washing program is selected by the user, by an amount (At) predetermined by the producer.
  • the user selects the washing duration (t1 ) that will be sufficient for effective washing in the case the softening unit (3) can perform adequate softening.
  • the control unit (7) provides the washing duration to be (t1 + At) when the selected washing duration (t1) is inadequate with the water that cannot be softened resulting from the detected error.

Consequently, the decrease in washing effectiveness resulting from hardness of water is compensated by increasing mechanical movements of the laundry in the drum (2) without making a change in the total washing duration (tr+ts) selected by the user.
