Definitions

  • This invention relates to a washer/dryer using microwave which reduces the risk of electrical arcing and an operation method providing the safe use of the washer/dryer.
  • microwave is used in the washing/drying cycles of preferably the front loaded washer/dryers in household appliances.
  • the metal accessories left and/or forgotten on the laundry can cause the electrical arcing and scorch the laundry.
  • an arc detection device is defined for the washer/dryers wherein the microwave is used.
  • the object of this invention is to provide a washer/dryer and a control method which use microwave and prevents the loading of the metal objects into the place where the microwave is used.
  • the washer/dryer (1) using microwave comprises a cover (11), which helps the loading and removal of the objects, a microwave applicator (2), which yields and applies the microwave and a control card (6) comprising preferably one or more memories.
  • the microwave applicator (2) comprises a magnetron (3) which yields microwave, an isolator (4) which protects the environment from the reflecting power, a microwave detector (7) either crystal or diode which controls the power of the microwave by detecting the excessive powers on the isolator (4) by means of the control card (6) and a wave guide (5) which leads the applied microwave to the desired direction.
  • the washer/dryer (1) which is the subject of this invention comprises a metal detector (8), which is placed not to be affected by the microwave and provides the detection of the arcing metal objects and one or more warning device (9) wherein the control card (6) informed by the metal detector (8) while the objects containing metal are being placed into the washer/ dryer (1) and warns the user by visual or audio means.
  • the warning device (9) comprises one or more select buttons (10), which provides the user with options such as the continuation of the operation of the warning device and/or applies them.
  • the main object of the microwave detector (7) is to prevent the arcing during the operation when the metal detector (8) does not work, it detects the metal objects by means of the differences in the reflections resulted from the control-targeted low amounts of microwave transmission in the first operation conditions and provides the warning for the user based on the control card (6), end of the operation or continuation of the operation without the use of microwave.
  • a front loaded washer/dryer (1) comprises a drum (21) pivotally rotating around an axis in which the laundry is put and a tub (22) in which the drum (21) moves.
  • Microwave applicator (2) is preferably on the tub (22) and the metal detector (8) is preferably on the tub (22) in a place where it is not affected by the microwave resulted from the microwave applicator (2) and is on the close side of the cover (11). Therefore the metal objects loaded into the device from the cover (11) part can be easily detected.
  • An operation method for the washer/dryer (1) which is the subject of this invention, comprises the steps of;
  • the washer/dryer which is the subject of this invention, can stop the arcing during the operation by detection, it can prevent the arcing by means of the detection of the causative objects prior the operation.

Claims (5)

  1. Wasch-/Trockenmaschine (1), die Mikrowellen verwendet, umfassend eine Mikrowellenanwendungseinrichtung (2), eine Steuerkarte (6), die die Mikrowellenanwendungseinrichtung (2) steuert, eine Mikrowellenerkennungseinrichtung (7), die Metallobjekte anhand von Differenzen in der Reflexion aufgrund von den gezielt gesteuerten niedrigen Mengen an Mikrowellenübertragung erkennt, eine Trommel (21), die sich um eine Achse dreht und in die die Wäsche gegeben wird, und einen Wasch-/Trockenbehälter (22), in dem sich die Trommel (21) bewegt,
    gekennzeichnet durch
    eine Metallerkennungseinrichtung (8), die Metallobjekte erkennt, welche Lichtbogenbildung verursachen könnten, während sie geladen werden, die auch erkennt, ob Metallobjekte entfernt wurden, und die den Benutzer warnt und somit für einen sicheren Betrieb und für die Steuerung der Wasch-/Trockenmaschine (1) sorgt, wobei die Metallerkennungseinrichtung in einer Position angebracht ist, die nicht von den darin übertragenen Mikrowellen beeinflusst wird, wobei die Wasch-/Trockenmaschine (1) derart konfiguriert ist, dass die Übertragung von Mikrowellen angehalten wird, wenn die von der Mikrowellenerkennungseinrichtung (7) erkannte Mikrowellenmenge höher als die von dem Hersteller vorgegebenen Werte ist, und derart, dass der Betrieb nur dann fortgesetzt wird, wenn die Metallerkennungseinrichtung (8) erkennt, dass das Metallobjekt entfernt wurde, wobei die Metallerkennungseinrichtung (8) am Wasch-/Trockenbehälter (22) an einer Stelle angeordnet ist, wo sie Metallobjekte erkennen kann, die in die Trommel (21) geladen oder aus der Trommel (21) entfernt werden.
