Definitions

  • the present invention relates to a washer-dryer enabling parameters of laundry items such as dryness, temperature, humidity to be measured precisely and accurately during the 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 are more conductive while humid.
  • the conductivity of the laundry decreases as they dry and lose their humidity.
  • the conductivity of only the laundry contacting the electrodes can be measured during drying.
  • the possibility of the electrodes to contact the laundry significantly decreases when there is a small amount of laundry in the drum which are not distributed homogeneously, thereby making it more difficult to determine drying. In this case, completion of drying is controlled by means of a timer. This, however, leads to an incomplete drying or the laundry being thermally damaged due to being over-dried.
  • KR20030041428 discloses a washer-dryer comprising a dryness detection unit provided in the drum, having electrodes fixed on the wall of the drum.
  • Another embodiment of the state of the art is disclosed in the international patent application no. WO2004022836 .
  • This patent application discloses a washer-dryer comprising a sensor provided on a drum, communicating with a control unit by contactless signal transmission.
  • Another embodiment of the state of the art is disclosed in the European Patent Application no. EP0940494 .
  • Said document also discloses a washer-dryer comprising a conductivity sensor used for detecting dryness of laundry items, and wirelessly communicating with a control unit.
  • Another embodiment of the state of the art is disclosed in the international patent application no. WO2007004173 .
  • 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 on which at least two electrodes are provided, placed in a drum together with the laundry items, moving freely with the laundry items 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; a seat provided on the control panel, in which the bearer is placed when not used in the drum; and a locking mechanism provided on the base of the seat and on the bearer, preventing the bearer from escaping the seat by mutually interacting when the bearer is placed in the seat.
  • the bearer is not required to be moved away from the washer-dryer to be recharged, thereby minimizing the risk of the bearer and
  • the locking mechanism consists of a first and a second holder of which the one provided on the seat is shaped as a projection and the one provided on the bearer is shaped as a recess.
  • the first and the second holders are magnets.
  • the first and the second holders are shaped as trapezoids with beveled corners and edges. This prevents the bearer from being inversely attached on the seat. Single way attachment of the bearer enables the charging pins and changing contacts to contact in full by enabling the charging pins to apply pressure on the charging contacts.
  • the bearer is shaped as a sphere and comprises at least one base on its wall.
  • the base consists the traverse of the bearer and is therefore annular.
  • the first holder is provided on said base and the bearer fits on the seat by means of said base.
  • the bearer comprises two bases on walls disposed opposite each other on the same diameter. The electrodes extend between said two bases.
  • the base of the seat and the base on the bearer are annular and are adapted for each other.
  • the energy needs of the bearer and the components provided therein are supplied by at least one battery positioned in the bearer and used as a power supply.
  • the washer-dryer further comprises a charging unit having charging pins and charging contacts provided on the bearer and the base of the seat, enabling the power supply on the bearer to be recharged by mutually interacting when the bearer is placed in the seat.
  • a charging unit having charging pins and charging contacts provided on the bearer and the base of the seat, enabling the power supply on the bearer to be recharged by mutually interacting when the bearer is placed in the seat.
  • 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 pitches formed on their edges. By this, humidity, vapor or water is prevented from penetrating the bearer in the drum which has a humid environment.
  • the washer-dryer (1) comprises a control unit by means of which its operational parameters are controlled, a drum in which the laundry items are placed, at least two electrodes (4) used to detect dryness of the laundry items by contacting the laundry items in the drum, a control panel (5) by means of which the user controls operation of the washer-dryer (1), and
  • the bearer (3) is placed by the user in the drum together with the laundry items, and the washer-dryer (1) is activated.
  • the electrodes (4) made of conductive material, provided on the bearer (3) and used for measuring the dryness level of the laundry items, move freely during the drying process together with the laundry items and independent of the drum, and collect real-time data from the laundry items. Since the bearer (3) can move freely in the drum, it contacts almost all of the laundry items in the drum, and enables receiving real-time dryness information from all of the laundry items.
  • the electrodes (4) are thus enabled to contact all of the laundry items independent of the amount and the distribution of the laundry items in the drum, thereby enabling collecting information about the parameters related to the dryness of the laundry items in the most precise and accurate manner.
  • the bearer (3) is removed out of the drum, the bearer (3) is placed on the seat (8) provided on the control panel (5), and unless a force is exerted thereon, it rests on the seat (8) by means of the locking mechanism (6).
  • the bearer (3) is kept on the seat (8) on the control panel (5) without being removed from the washer-dryer (1) when it is not utilized in the drum. This minimizes the risk of losing the bearer (3) likely to occur due to keeping it in a location away from the washer-dryer (1).
  • the locking mechanism (6) comprises a first holder (9) provided on the bearer (3) and a second holder (10) provided on the base of the seat (8), engaging into the first holder (9), of which one is preferably shaped as a projection and the other as a recess.
  • the first and the second holders (9 and 10) are magnets.
  • the bearer (3) is shaped as a sphere and comprises at least one base (7) on its wall.
  • the base (7) constitutes the traverse of the bearer (3).
  • the first holder (9) is provided on said base (7) and the bearer (3) fits on the seat (8) by means of said base (7).
  • the bearer (3) comprises two bases (7) on walls disposed opposite each other on the same diameter.
  • the electrodes (4) extend between said two bases (7).

  • the washer-dryer (1) comprises a charging unit (11) provided on the bearer (3) and the base of the seat (8), enabling the power supply on the bearer (3) to be recharged by mutually interacting when the bearer (3) is placed in the seat (8).
  • the charging unit (11) comprises two charging pins (12) provided on the base of the seat (8) and two charging contacts (13) provided on the base (7) of the bearer (3).
  • the charging pins (12) contact the charging contacts (13), enabling transmitting energy to the power supply.
  • the seat (8) functions as a charging unit enabling charging the power supply provided in the bearer (3) and the bearer (3) is thus recharged on the seat (8).
  • the power supply provided in the bearer (3) is enabled to be electrically connected to an energy source and be recharged by means of the seat (8) on the control panel (5).
  • the bearer (3) is enabled to be recharged on the control panel (5), without being removed from the washer-dryer (1) ( Figure 3 and Figure 4 ).
  • the first and the second holders (9 and 10) are shaped as trapezoids with beveled corners and edges. This prevents the bearer (3) from being inversely attached on the seat (8). Single way attachment of the bearer (3) enables the charging pins (12) and changing contacts (13) to contact in full by enabling the charging pins (12) to apply pressure on the charging contacts (13).
