Description

  • The present invention relates to a method for operating a washing machine for washing with water, said washing machine comprising a gas sensor.
  • Detecting the level of dirtiness of the laundry to be washed in the washing machine and determining the washing parameters accordingly is important in terms of energy, water, detergent savings. In the state of the art embodiments detecting the level of dirtiness of laundry is based on the principle of measuring the parameters of turbidity, pH, conductivity, surface tension etc. of the suspension after dirt mixes in the washing suspension. In these embodiments, since the detection process is performed after the dirt mixes in the washing suspension, the completion of the washing process is controlled more than the performance of washing depending on the dirt amount. Moreover, it is not possible to carry out optimum washing programs according to the level of dirtiness of laundry at the start of washing since the washing parameters can be determined after detecting the dirtiness. Therefore, the level of dirtiness of the laundry is required to be determined at the start of the washing process.
  • In the state of the art European Patent Application No. EP1602766 , a washing machine is described wherein the odor of laundry placed therein is detected by means of an odor sensor and deodorizing process is performed independently of the washing process.
  • WO 2005/003428 describes a method for performing a laundry process in a non-aqueous laundering apparatus.
  • The aim of the present invention is obtained by means of a washing machine wherein the level of dirtiness of the laundry is detected and the washing process is performed in accordance with this detection.
  • The washing method attaining the aim of the present invention is described in the attached claims.
  • In the method for operating a washing machine of the present invention for washing with water, the washing machine comprises a gas sensor that detects odors of the laundry and a control unit that determines the level of dirtiness of laundry by evaluating the odors detected with the gas sensor. The control unit further determines the washing parameters according to the level of dirtiness of the laundry and provides the washing process to be performed in compliance with these parameters. Unnecessary consumption of energy, time and water is prevented by determining the washing parameters like the washing temperature, rotation and stop times of the drum, the total water amount, the total washing time in accordance with the level of dirtiness of the laundry.
  • The gas sensor is disposed in the drum or between the drum and the tub. When the gas sensor is disposed between the drum and the tub, the reliability of the measurements taken by the gas sensor is increased by positioning the gas sensor at a point near to the laundry.
  • The process of detecting odor of the laundry is performed before the start of the washing process, in other words when water is not yet received into the washing machine. The detected odor values are delivered to the control unit and level of dirtiness of the laundry and the relevant washing parameters are determined by the control unit. Washing performance is improved by determining the washing parameters at the start of washing according to the level of dirtiness of the laundry.
  • In an embodiment of the present invention an air flow conduit is disposed between the gas sensor and the drum. A pump is provided on the flow conduit to be situated prior to the gas sensor. The door of the washing machine is closed after the laundry is placed and the drum air is delivered to the gas sensor by operating the pump.
  • In another embodiment of the present invention, the drum is rotated several times before performing odor detection process by the gas sensor. Consequently, the odor in the laundry is provided to diffuse into the drum and measurement reliability of the gas sensor is increased.

After the washing machine (1) door is closed upon placing the laundry (L) in the drum (3), the air in the drum (3) is provided to be delivered to the gas sensor (5) by operating the pump (8). In a version of this embodiment, the drum (3) air passed from the gas sensor (5) is again directed into the drum (3) through the other end of the flow conduit (7). In yet another version of this embodiment, the drum (3) air passed over the gas sensor (5) is discharged to the outside surrounding after the measurement.
  • In an embodiment of the present invention, the gas sensor (5) detects the volatile organic compounds causing dirtiness in the laundry (L) before water is received into the tub (4), after the drum (3) is rotated several times.
