Definitions

  • the present invention relates to a washing machine wherein the flow of water delivered onto the laundry is optimized.
  • washing machines have a fixed tub and a drum rotating in the tub.
  • a pump and a circulation line which ensure that the washing water taken from the lower part of the tub is sent back into the drum via the upper part of the tub.
  • water is sprayed on the laundry by means of nozzles on the bellows.
  • the water coming through the circulation line is fed onto the laundry through the baffles in the drum.
  • the washing water coming from the circulation line first fills into the baffle and then is sprayed onto the laundry through the nozzles on the baffle.
  • the position of the baffles relative to the inlet to the tub is provided by the communication between the sensor unit and the control unit.
  • the washing performance is increased by means of the extra water circulation provided in the washing machines wherein water is delivered onto the laundry through the baffles.
  • the sprayed water always reaches the laundry with a constant flow form and pressure. Therefore, the baffles are always designed to provide optimum mechanical movement for the purpose of maximum cleaning. Therefore, more mechanical damage occurs during the washing of delicate fabrics, while a lower washing performance is obtained in the washing of fabrics with heavy stains. Since the water sent back into the drum with the drum baffle in the existing systems has a constant pressure and flow pattern, it is insufficient to provide high washing performance and prevent mechanical damage.
  • the aim of the present invention is the realization of a washing machine wherein laundry of different types and/or with different characteristics are efficiently washed.
  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a tub; a drum which is disposed in the tub; a motor which rotates the drum in the tub; a tub outlet which is provided at the lower side of the tub; a circulation line which extends between the tub outlet and a tub inlet provided at the upper side of the tub; a pump which is provided on the circulation line and which enables the water taken through the tub outlet to be sent to the tub inlet; a first baffle which is provided on the drum and which has a first port suitable for taking the water coming through the tub inlet and at least one first nozzle which enables the water filled therein through the first port to be sent into the drum; a second baffle which is provided on the drum and which has a second port suitable for taking the water coming through the tub inlet and at least one second nozzle which enables the water filled therein through the second port to be sent into the drum; at least one sensor unit which is suitable for sensing the position of the first baffle
  • a turbidity sensor in the tub which detects the turbidity of the water in the drum
  • the control unit controls the motor and pump so as to ensure that when the turbidity value detected by the turbidity sensor is higher than a threshold turbidity value determined by the manufacturer, the first port on the first baffle is aligned with the tub inlet in order to spray water into the drum by means of the first baffle suitable for removing heavy stains and that when the turbidity value detected by the turbidity sensor is lower than the threshold turbidity value, the second port on the second baffle suitable for washing delicate fabrics is aligned with the tub inlet.
  • the washing performance of the washing machine is increased by ensuring that laundry with heavy stains is exposed to more mechanical action.
  • the number of second nozzles provided on the second baffle is greater than the number of first nozzles provided on the first baffle.
  • the second drum baffle is configured to transfer water not only to a specific area, but to almost the entire drum. Consequently, mechanical damage to the laundry is prevented and the washing process is performed effectively by increasing the surface area in contact with water.
  • a plurality of first nozzles are positioned at the center of the surface of the first baffle facing the inside of the drum so as to form an almost circular area without being scattered over the entire surface.
  • the second baffle comprises a nozzle surface having a plurality of second nozzles, and there are a plurality of second nozzles on the nozzle surface, which are homogeneously positioned so as to spread over almost the entire nozzle surface.
  • the laundry when a delicate program suitable for washing delicate laundry is selected via the control panel by the user, the laundry is washed only with the water transferred from the second baffle via the second nozzle. It is ensured that water is sprayed in the form of light sprinkling on delicate textiles (for example, silk). Thus, the economic life of the fabrics is extended by preventing the delicate laundry from being damaged.
  • the laundry when an intensive washing program suitable for washing non-delicate or heavily stained laundry is selected by the user, the laundry is washed only with the water transferred from the first baffle via the first nozzle.
  • the first baffle is used during the washing of non-delicate fabrics such as synthetic, cotton, etc. or stained laundry, the water is enabled to reach the laundry in a focused manner such that the laundry is washed effectively.
  • the washing water is prevented from being delivered into the drum with a constant pressure and flow pattern, and thus the laundry is washed effectively and without causing any mechanical damage.
  • the washing machine (1) comprises a tub (2); a drum (3) which is disposed in the tub (2); a motor (4) which rotates the drum (3) in the tub (2); a tub outlet (5) which is provided at the lower side of the tub (2); a tub inlet (6) which is provided at the upper side of the tub (2); a circulation line (7) which extends between the tub inlet (6) and the tub outlet (5); a pump (8) which is provided on the circulation line (7) and which enables the water taken through the tub outlet (5) to be sent to the tub inlet (6); a first baffle (11) which is provided on the drum (3) and which has a first port (9) suitable for taking the water coming through the tub inlet (6) and at least one first nozzle (10) which enables the water filled therein through the first port (9) to be sent into the drum (3); a second baffle (14) which is provided on the drum (3) and which has a second port (12) suitable for taking the water coming through the tub inlet (6) and at least one second nozzle (13) which enables the water
