Definitions

  • 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.
  • 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.
  • the completion of the washing process is controlled more than the performance of washing depending on the dirt amount.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • control unit after determining the level of dirtiness of the laundry according to odor detected by the gas sensor, informs the user on this matter by transmitting the level of dirtiness to the display. Accordingly, the user is provided to use the optimum amount of detergent by taking into consideration the level of dirtiness of the laundry.
  • the level of dirtiness of the laundry placed into the drum and the washing parameters in accordance with this level of dirtiness are provided to be determined.
  • the washing machine (1) comprises a body (2), a drum (3) disposed in the body (2) wherein the laundry (L) is placed, a tub (4) wherein the drum (3) moves, a gas sensor (5) placed in the drum (3) or between the drum (3) and the tub (4) that detects volatile organic compounds causing dirt in the laundry (L) and a control unit (6) that determines the level of dirtiness of the laundry (L) and the washing parameters according to the level of dirtiness by evaluating data received from the gas sensor (5) and provides to perform the washing process according to these parameters ( Figure 1 ).
  • Most of the dirt contained in the laundry (L) is made up of body dirt.
  • the dirt amount in approximately 3 kilograms of laundry varies between about 10 g. to 100 g.
  • the rate of visible stains among this dirt is approximately 25 % and the rate of body dirt is nearly 75 %.
  • the level of dirtiness of the laundry (L) placed in the drum (3) for washing is determined by detecting the amount of volatile organic compounds present in the body dirt that cause dirtiness in the laundry (L) by means of the gas sensor (5).
  • the odor values of the laundry (L) placed into the drum (3) are detected by the gas sensor (5) and the detected odor values are delivered to the control unit (6).
  • the levels of dirtiness corresponding to the odor values of the laundry (L) obtained with previously taken measurements by the producer are recorded in the memory of the control unit (6).
  • the control unit (6) determines the level of dirtiness of the laundry (L) by comparing the data recorded in its memory with the data detected by the gas sensor (5). For example, the control unit (6) determines the level of dirtiness of the laundry (L) as low, medium or very dirty as a result of the evaluation.
  • the control unit (6) executes the washing process by using the washing parameters like the washing temperature, mechanical movement percentage (the percentage of drum (3) rotation and stop) and the total washing time recorded in its memory depending on the level of dirtiness of the laundry (L). Unnecessary energy, time and water consumption is prevented by determining the washing parameters in accordance with the level of dirtiness of the laundry (L). Moreover, washing performance is improved by selecting the washing parameters according to the level of dirtiness of the laundry (L).
  • the gas sensor (5) When the gas sensor (5) is disposed between the drum (3) and the tub (4), the gas sensor (5) is provided to take measurement from the area closest to the laundry (L).
  • the gas sensor (5) detects the volatile organic compounds that cause dirtiness in the laundry (L) before the washing process starts.
  • the process of detecting odor and hence the dirtiness of the laundry (L) by the gas sensor (5) is realized after the laundry (L) is placed in the drum (3) and the door of the washing machine (1) is closed before the washing machine (1) receives water.
  • the detected odor values are delivered to the control unit (6).
  • the control unit (6) determines the level of dirtiness of the laundry (L) and the washing parameters depending on the odor values delivered thereto. Energy and water savings are provided by determining the washing parameters at the start of washing according to the level of dirtiness of the laundry (L).
  • the gas sensor (5) detects the volatile organic compounds that cause dirtiness in the laundry (L) at intervals predetermined by the producer during the washing.
  • the odor amount of the laundry (L) is detected by means of the gas sensor (5) at certain intervals and delivered to the control unit (6).
  • the control unit (6) determines the level of dirtiness according to the detected odor amount and updates the required washing parameters relating to the continuation of the washing. For example, whether or not additional rinsing is necessary is evaluated by the control unit (6) depending on the odor value detected after the first rinsing. Consequently, the washing performance of the laundry (L) is improved by the gas sensor (5) performing the odor detection process in different steps of the washing.
  • the washing machine (1) comprises a flow conduit (7) that connects the drum (3) and the gas sensor (5) to each other and a pump (8) disposed on the flow conduit (7) which delivers the air in the drum (3) to the gas sensor (5) ( Figure 2 ).
  • the air in the drum (3) is provided to be delivered to the gas sensor (5) by operating the pump (8).
  • 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).
  • the drum (3) air passed over the gas sensor (5) is discharged to the outside surrounding after the measurement.
  • 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. Upon activation of the drum (3), the odor in the laundry (L) is provided to be more disseminated inside the drum (3). Consequently, the measurement precision of the gas sensor (5) is increased.
  • the washing machine (1) comprises a display (9) which transmits the level of dirtiness of the laundry (L) inside the drum (3) detected by the gas sensor (5) to the user.
  • the odor of the laundry (L) placed inside the drum (3) is detected by the gas sensor (5) and delivered to the control unit (6).
  • the control unit (6) determines the level of dirtiness of the laundry (L) by comparing with the reference values recorded in its memory and transmits this to the display (9). Consequently the user can adjust the amount of detergent used in the washing process being informed about the level of dirtiness of the laundry (L). Accordingly, in the case the laundry (L) is less dirty the damage to the environment is decreased by using less detergent, and in the case the laundry (L) is very dirty the washing effectiveness is improved by using more detergent.
  • the level of dirtiness of the laundry (L) placed into the drum (3) can be detected by means of a gas sensor (5).
  • the washing parameters are determined according to the level of dirtiness of the laundry (L) and the washing process is executed accordingly. Consequently, savings in energy, water and time are provided in the washing process.
