Definitions

  • the present invention relates to a washer/dryer wherein the open or closed position of the diverter valve is determined.
  • the detergent dispensers which are continuously used by the user get dirty and adversely affect sensory perception for a number of reasons.
  • the dirt in the detergent dispenser can be caused by textile particles formed during the washing and/or drying of the laundry, or caused by the detergent and softener loaded before each washing process remaining on the dispenser surface. Due to the detergent and softener residues remaining on the humid dispenser surface, visible and bacterial formations occur on the dispenser surface, which adversely affects the perception and health.
  • the detergent residues on the dispenser surfaces get dry and must be cleaned by the user before each drying process.
  • One of the cleaning methods includes the guiding of the water preheated in the washer/dryer back into the detergent dispenser.
  • the water is guided into the detergent dispenser by the diverter valve.
  • the water flow from the pump outlet is divided into two by means of the diverter valve.
  • the diverter valve delivers the water to the jet nozzle group or detergent cleaning group. With the use of the diverter valve, the water is guided to two different directions. When the diverter valve is open, the water is delivered into the detergent dispenser, and when closed, the water is discharged. As the water may continuously change direction, the diverter valve continuously moves. This movement causes problems of noise and leakproofing.
  • it is required to determine whether the diverter valve is active or not.
  • the diverter valve operates thanks to a thermoactuator therein.
  • the shutter in the diverter valve enables the water to be guided to different outlets. When not energized, only one outlet of the diverter valve is open and when energized the other outlet is opened.
  • the problem in these embodiments is that when the diverter valve is energized, the outlet direction is not changed and/or when not energized the shutter does not return to its previous position. In such conditions, safety problems may arise. Therefore, it is very critical to determine whether the diverter valve is open or closed and at which position.
  • a laundry washing machine comprising a diverter valve fixed onto the side wall of the body.
  • the laundry washing machine comprises a detergent dispenser which can be easily cleaned and which is composed of a plurality of detachable containers.
  • a washer/dryer comprising a control method for controlling the diverter valve fixed onto the body.
  • the aim of the present invention is the realization of a washer/dryer wherein it is determined whether the diverter valve is open or closed.
  • the washer/dryer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises at least one impeller disposed at the outlet of the diverter valve and at least one sensor which detects the rotational movement of the impeller as a result of the impact of the water.
  • the movement of the impeller is detected by a movement sensor.
  • the impeller is connected to the second outlet of the diverter valve to which the pipe delivering water to the detergent dispenser is connected, and is located between the diverter valve and the detergent dispenser.
  • the water impacts the impeller disposed in the pipe delivering the water towards the detergent dispenser after leaving the diverter valve, and the water continues its flow towards the detergent dispenser.
  • the change in the position of the impeller is detected by the sensor and it is easily and simply determined through which outlet the water passes.
  • the impeller is connected to the first outlet of the diverter valve to which the pipe spraying water into the drum is connected.
  • the impeller is positioned between the diverter valve and the drum.
  • the senor comprises a magnet disposed at the hub of the impeller and a sensing element which detects the magnetic field of the magnet.
  • a jet pump is used to deliver water into the detergent dispenser at certain intervals.
  • the jet pump and the water heater are operated before the washing and/or drying program and while first cold water is delivered, with the heating of the water hot water is delivered into the detergent dispenser.
  • precleaning is carried out at the beginning of the process and cooling is carried out at the end of the process.
  • a small amount of cold water is delivered from the diverter valve into the detergent dispenser, thus decreasing the temperature of the surfaces of the detergent dispenser.
  • the cleaning program is started both with the user pushing the cleaning button and at the end and beginning of certain washing/drying cycles.
  • the water is guided to two different directions.
  • the diverter valve When the diverter valve is open, the water is delivered into the detergent dispenser, and when closed, the water is discharged.
  • the diverter valve By determining whether the diverter valve is active or not, water containing fibers and detergent is prevented from being delivered into the detergent dispenser while being discharged.
  • the cleaning process can be carried out at higher temperatures.
  • the detergent dispenser can be cleaned at the end of each washing process.
  • the detergent dispenser can be cleaned after a certain number of washer/dryer operations determined by the user or the producer.
