Definitions

  • the present invention relates to a washer-dryer comprising a bearer enabling parameters of laundry items, such as dryness, temperature, humidity to be measured precisely and accurately during drying process.
  • washer-dryers during drying process, parameters of the laundry items in a drum such as dryness, temperature, etc. have to be measured precisely and accurately. The duration of drying process depends on the laundry items reaching the accurate levels of dryness and temperature, and upon reaching of said levels drying process is terminated.
  • Various sensors are provided on washer-dryers, enabling measuring parameters such as conductivity, temperature, humidity, etc., and the washer-dryer is controlled by means of the data received from such sensors.
  • conductivity is measured during drying process and drying process is terminated according to this measurement.
  • Conductivity is measured by means of two electrodes stably placed at the front portion of a drum. During drying process, the conductivity value of the laundry items can be measured when the laundry items in the drum contact said electrodes.
  • Laundry items are more conductive in humid state.
  • the conductivity of the laundry items decreases as it dries and loses its humidity.
  • the conductivity of only the laundry items contacting the electrodes can be measured during drying.
  • the possibility of the electrodes contacting the laundry items significantly decreases when there is a small amount of laundry items in the drum which are not distributed homogeneously, thereby making it more difficult to determine drying. In this case, drying process is terminated by a timer. This, however, leads to drying process not being fully performed or the laundry items being thermally damaged by being over-dried.
  • EP2387643 discloses a washer-dryer having a drum rotating in horizontal axis, the washer-dryer comprising electrodes fixed on the inlet port of the drum by way of plastic injection, enabling detecting dryness.
  • Korean Patent Application no. KR20030041428 discloses a washer-dryer comprising a dryness detection unit provided in the drum, having electrodes fixed on the wall of the drum.
  • the aim of the present invention is to realize a washer-dryer in which parameters such as dryness and temperature are enabled to be measured precisely and accurately during drying process.
  • the washer-dryer realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a bearer placed in a drum together with laundry items, moving freely in the drum, enabling accurately and precisely measuring the parameters related to the dryness of the laundry items such as humidity, temperature, and dryness by contacting all of the laundry items, on which at least one sensor is provided, and a seat provided on the control panel, enabling the bearer to be charged by being placed thereon and to be further used as a button.
  • the position of the bearer in the seat is determined according to the magnetic field generated by a primary coil provided in the seat, and the voltage values measured by means of the coils on each of the three axes of the secondary coil wound over the bearer.
  • the bearer is thus enabled to be used as a conductivity sensor in the drum, and as a button on the control panel out of drum.
  • the bearer is not required to be moved away from the washer-dryer to be charged, thereby minimizing the risk of the bearer and the charging unit getting lost.
  • the position of the bearer in the seat is determined according to the relation between the voltage values on the secondary coils wound on three axes, measured when the bearer is at any position and the magnetic field generated by means of the primary coils provided on the seat.
  • voltage is loaded on said secondary coils and the power supply can be easily charged independently of the bearer's position.
  • the control unit obtains the initial position of the bearer by means of the voltages acquired and directed separately from each axis.
  • the voltage values detected from all three axes in the initial position are compared to the maximum voltage value that could be received from each one of the axes, i.e. the value of voltage on the secondary coils in the position in which it is fully perpendicular to the magnetic field.
  • the same calculation is also performed for the second position.
  • the differences between the voltage values in two separate positions and the degree of being offset from the perpendicular position is obtained in percent value for each axis.
  • the condition for cable-free charging that the magnetic field generated in the seat and the secondary coils positioned in the bearer having to be perpendicular to each other is met without considering how the bearer is positioned thanks to the secondary coils wound on all of the three axes.
  • the position of the bearer in the seat is exactly determined by detecting the position in at least two dimensions, enabling the user interface to be used more effectively.
  • the energy needs of the bearer and the units provided therein are supplied by at least one battery positioned in the bearer and used as a power supply.
  • the bearer is shaped as a hollow chamber, and in the preferred embodiment, it consists of two parts, namely the upper and lower parts, and is preferably shaped as a sphere.
  • the upper and lower parts are firmly and sealingly joined to each other by the screw threads formed on their sides. By this, humidity, vapor or water is prevented from entering into the bearer in the drum with a humid environment.
  • the bearer insulated completely from the outer environment by means of the present invention is wirelessly charged via the control panel.
  • AC voltage is induced on the secondary coils positioned on the inner surface of the bearer by means of a magnetic field. Said voltage is directed and regulated, and is used for charging the power supply.
  • the primary coils enabling inducing voltage for charging are disposed on the rear surface of the seat. By this, insulation is provided and the appearance is not compromised.
  • the secondary coil is wound in a helical shape on three axes perpendicular to each other.
  • One of the significant advantages of the invention is being able to use the wireless communicating bearer as a button by detecting its position on the seat in at least two dimensions.
  • bearer is used in the drum as a conductivity detector, and out of the drum, it is also used as a button on the control panel.
  • the position of the bearer in the seat can be exactly determined in at least two axes and without requiring utilization of an additional sensor, by observing the difference between the components perpendicular to the magnetic field generated by means of the primary coils.
  • the user interface is thus enabled to be used effectively.
  • the bearer is enabled to be charged in all positions, independent of its position thanks to the coils wound on all three axes.
  • the information relating to the position of the bearer in the seat can be obtained without using an additional sensor, and the bearer is enabled to be used as an improved button. Humidity, heat and fluid insulation is fully provided as there are no coupling members between the interior and the exterior of the bearer.

  • the sensor (4) provided on the bearer (4) and used to determine at least one physical condition of the laundry items such as dryness, temperature or humidity, moves freely during drying process together with the laundry items and independent of the drum (2), and collects real-time data from the laundry items. Since the bearer (3) can move freely in the drum (2), it contacts almost all of the laundry items in the drum (2), and enables receiving real-time dryness information from all of the laundry items.
  • the sensor (4) is thus enabled to contact all laundry items independent of the amount and the distribution of the laundry items in the drum (2), thereby enabling collecting the information of the parameters related to the dryness of the laundry items in the most precise and accurate manner.

  • the secondary coils (12) are the coils provided on the bearer (3), energized by the magnetic field generated by the primary coil (11).
  • the secondary coils (12) should be positioned perpendicularly to the magnetic field generated by the primary coils (11) for current to form thereon. Otherwise, the transmitted amount energy decreased or energy transmission is canceled out. Therefore, for the transmitted energy not to be canceled out at all, secondary coil (12) is formed and wound on the bearer (3) on all three axes perpendicular to each other.
  • the control unit (7) obtains the initial position of the bearer (3) by means of the voltages acquired and directed separately from each axis.
  • the voltage values retrieved from each of the three axes in the initial position are compared to the maximum voltage value that could be received from each one of the axes, i.e. the value of voltage on the secondary coils (12) in the position in which it is fully perpendicular to the magnetic field.
