Definitions

  • the present invention relates to a washing machine wherein the washing process is realized for white and colored washing.
  • washing machines operated by a single button wherein user intervention in the washing algorithm is minimal, it is important to determine which washing process is the suitable one by detecting the color of the laundry.
  • the information on the weight, type of the laundry as well as the color plays an important role.
  • the duration and temperatures of the washing and rinsing steps differ in the washing programs to be implemented for colored or white laundry.
  • the washing machine is operated after sorting the laundry according to their colors.
  • washing control is established or the user is warned by detecting the release of laundry dye in the wash water during the washing operation.
  • detection is made depending on the release of dye into the wash water, the washing has to be made for a certain time period.
  • the distinction of white and colored laundry is not very reliable.
  • release of dye into the wash water is taken as the base in determining the colors, the washed laundry is discolored.
  • International Patent Application WO 01/46509 A1 discloses an appliance for handling textiles comprising at least one emitting unit and at least one receiving unit for electromagnetic radiation and connected to an evaluation circuit. Thus the chemical composition of the textiles can be determined and a drying process can be controlled accordingly.
  • the object of the present invention is to design a washing machine wherein the color of the laundry is determined before starting the washing process and the colored or white washing process is carried out depending on the color data.
  • the washing machine designed to fulfill the object of the present invention, ex-plicated in the first claim and the respective claims thereof, comprises a color sensor providing to detect the color of the laundry emplaced therein and a control unit that determines the washing parameters before starting the washing process according to the color data received from the color sensor.
  • the color sensor Since the color sensor is in the active position independent from the operation of the washing machine, the color of the laundry emplaced in the drum by the user can be detected even when the washing machine is in the off position. Accordingly, the color of the laundry emplaced in the drum can be detected either just before the washing process or when laundry is emplaced in the drum at spaced apart intervals and can be evaluated by the control unit.
  • the color sensor detects simultaneously with a presence sensor disposed at the loading port. In this embodiment, erroneous detection resulting from the hand of the user or any other factor of the outer environment is prevented.
  • the washing machine comprises preferably a white light source.
  • the light source which is energized as the laundry is emplaced into the drum through the loading port, provides to adjust the lighting level of the region to be detected by the color sensor. Accordingly, faulty color detection is prevented in the region that does not always have the same light intensity.
  • White light emitting diode is used as the light source for convenience of use and costs.
  • the washing machine comprises an indicator that displays for the user whether the laundry in the drum at that moment is colored or white according to the color values detected by the color sensor. Furthermore the indicator warns the user momentarily if the color of the newly placed laundry in the drum is different from the color values of the laundry determined earlier. Consequently, the user can load laundry in the drum knowing whether the previously loaded laundry in the drum is colored or white.
  • the color sensor can be changed to the active or passive position with a button by the user.
  • the washing machine (1) of the present invention comprises a drum (2) wherein laundry (L) is emplaced, a loading port (6) for loading and unloading of laundry (L) into the drum (2) by the user, a color sensor (4) that detects the color of the laundry (L) while the laundry (L) is loaded into the drum (2) or afterwards and a control unit (3) that decides whether the laundry (L) to be washed is colored or white according to the detected color data before starting the washing process and then starting the washing process by determining the washing parameters depending on this data ( Figure 1 ).
  • the color sensor (4) is preferably disposed on the loading port (6) of the drum (2) or on the bellows situated at the loading port (6). Accordingly the color data of the laundry (L) can easily be detected while the laundry (L) is being loaded into the drum (2).
  • the color sensor (4) and the control unit (3) can be fed by energy sources such as batteries etc. independently from the power supply. By this means, the colors of the laundry (L) emplaced in the washing machine (1) at different times can be detected before operating the washing machine (1) and are transmitted to the control unit (3) to be stored and evaluated.
  • the washing machine (1) While the laundry (L) is being loaded into the drum (2) by the user and/or after loading, the colors thereof are detected by the color sensor (4) and the color data is transmitted to the control unit (3) to be stored until the washing machine (1) starts operating.
  • the color data values stored in the control unit (3) is analyzed and compared with a value predetermined by the producer. As a result of this comparison process, it is decided whether the laundry (L) emplaced in the drum (2) is colored or white.
  • the washing parameters are determined depending on this decision and the washing process is implemented according to these parameters.
  • the washing machine (1) furthermore comprises a presence sensor (5).
  • the presence sensor (5) is disposed on the loading port (6) and the entry of each piece of laundry (L) loaded into the drum (2) is detected.
  • the color data of the laundry (L) is detected simultaneously and transmitted by the color sensor (4) to the control unit (3). Consequently, while the laundry (L) is being loaded into the drum (2) through the loading port (6), erroneous detection by the insertion of the user's hand into the detection area of the color sensor (4) is prevented.
  • it is assumed that the loaded laundry (L) will enter the detection area of the color sensor (4) before the user's hand ( Figure 2 ).
  • the laundry (L) while the laundry (L) is emplaced into the drum (2), the laundry (L) passes through the detection area of the presence sensor (5) and the presence sensor (5) changes to the active position.
  • the presence sensor (5) becomes active
  • the color sensor (4) also becomes active and detects the color of the laundry (L) passing through the detection area thereof. Consequently, the color data of each piece of laundry (L) emplaced into the drum (2) is detected by the color sensor (6) and stored in the control unit (3).
  • the washing machine (1) comprises an indicator (7) that displays for the user whether the laundry (L) in the drum (2) at that moment is colored or white.
  • the indicator (7) momentarily warns the user if the color of the new piece of laundry (L) loaded into the drum (2) is different from the color value of the laundry (L) determined previously. Consequently, the user knows whether the previously loaded laundry (L) in the drum is colored or white, then loads laundry (L) into the drum (2) accordingly.
  • the washing machine (1) comprises preferably a white light source (8) that is disposed in the vicinity of the color sensor (6) such that the detection area of the color sensor (6) is illuminated.
  • the light source (8) that is activated while the laundry (L) is being loaded into the drum (2) through the loading port (6), illuminates the area that will be detected by the color sensor (4), providing to adjust the light level in that area. Consequently, incorrect color detection by the color sensor (4) in that area that does not always have the same light intensity is thus prevented.
  • a white LED light emitting diode
  • a white LED is used as the light source (8) for use of convenience and costs.
  • the color data of the laundry (L) loaded into the washing machine (1) is collected by utilizing various optical and imaging systems (camera, infrared scanners, infrared imaging devices etc.).
  • the washing machine (1) comprises a button that enables the user to change the color sensor (4) to the active or passive position.
  • the determination of colored-white laundry (L) can be made for the laundry (L) emplaced into the drum (2) by utilizing the color sensor (4) before starting the washing process.
  • the washing parameters are determined depending on the colored-white laundry (L) differentiation and the washing process is started accordingly.
  • the determination of the washing operation depending on the color of the laundry (L) can be made independently from the user.
