Definitions

  • the present invention relates to a washing machine comprising a dispenser wherein washing agents are placed.
  • the washing agent required for the cleaning process is placed into a dispenser.
  • the wash water received from the water inlet is directed into the dispenser.
  • the dissolved–melted washing agent passes into the washing tub together with the water.
  • the dispensers generally comprise partitions wherein powder and/or liquid washing agents are placed and at least one water inlet that provides delivery of water into the partition. Mold forms in the inner portions of the partition and the water inlet in the course of time since the said partition and the water inlet remain wet after the washing. This situation is unfavorable in terms of hygiene. Furthermore, these parts remaining wet causes the washing agent used in the next washing to lump by gathering moisture and it becomes difficult to deliver the lumped washing agent into the washing tub with the washing water.
  • washing agent dispenser Another problem encountered as a result of the washing agent dispenser and the water inlet remaining wet is that when the weather is very cold, the water in these sections freezes, thereby adversely affecting the effectiveness of the washing machine.

  • the interior of the dispenser is provided to be dried by delivering the dry air into the dispenser. Consequently, the formation of microorganisms inside the dispenser is prevented and if present, the formed microorganisms are provided to be exterminated. Formation of odor due to the mold inside the dispenser is also prevented.
  • the washing machine comprises a fan that provides the humid air inside the tub or the dispenser or the outside environment air to be sucked and a suction channel that provides the air sucked by the fan to be delivered to the dehumidifying unit and to pass through the desiccant material.
  • the washing machine comprises at least one first valve that enables the determination of the amount of air to be delivered to the dehumidifying unit from the tub, the dispenser or the outside environment. Consequently, drawing of humid air from the section that is more in need of drying (the tub or the dispenser) and drying of that section is provided.
  • the washing machine comprises a first suction channel that extends between the dispenser and the dehumidifying unit.
  • the amount of air that passes through the first suction channel is controlled by means of the first valve.
  • the washing machine comprises a second suction channel that extends from the tub towards the dehumidifying unit. Only the dry air that is delivered to the tub passes through the second suction channel.
  • the washing machine comprises at least one second valve that enables the determination of the amount of air to be delivered from the dehumidifying unit to the tub or the dispenser.
  • the delivery of more heated and dry air is provided to the section (the dispenser or the tub) that is in more need of drying.
  • the washing machine comprises a first pumping channel that extends between the second valve and the dispenser. Delivery of air only from the dispenser to the dehumidifying unit is provided by means of the first pumping channel.
  • the washing machine comprises a second pumping channel that extends between the second valve and the tub. Delivery of air only from the tub to the dehumidifying unit is provided by means of the second pumping channel.
  • the washing machine comprises at least one heater that provides the heating of the desiccant material.

  • the dispenser is prevented from remaining wet and formation of biofilm or bad odor inside the dispenser is prevented.
  • the washing machine comprising a dispenser with improved hygienic and utilization features is realized.
  • Figure 1 – is the schematic view of the washing machine of the present invention.
  • the washing machine (1) comprises a body (2), a tub (3) wherein the washing process is performed and a dispenser (4) wherein the cleaning agents are placed.

  • the dispenser (4) is provided to be dried by heating and the disadvantages that occur as the result of the dispenser (4) remaining wet are prevented ( Figure 1).
  • the washing machine (1) comprises a fan (8) that sucks and delivers the air towards the dehumidifying unit (6) and a suction channel (9) that enables the delivery of the air sucked by the fan (8) to the dehumidifying unit (6).
  • the air coming from the tub (3), the dispenser (4) or the outside environment is sucked by the fan (8) and delivered to the dehumidifying unit (6) by means of the suction channel (9). Consequently, the dispenser (4) is provided to be dried after the humid air inside the tub (3) or the dispenser (4) is heated and dried by means of the dehumidifying unit (6).
  • the washing machine (1) comprises at least one first valve (10) disposed on the suction channel (9) and that enables the controlling of the passage of air received from the dispenser (4) and/or the tub (3) to the dehumidifying unit (6).
  • the amount of air received from the dispenser (4), the tub (3) or the outside environment and delivered to the dehumidifying unit (6) is controlled by means of the first valve (10).
  • the delivery of air from the tub (3) to the dehumidifying unit (6) is prevented by means of the first valve (10).

  • the washing machine (1) comprises a first suction channel (109) with one end connected to the dispenser (4), that extends from the dispenser (4) towards the dehumidifying unit (6) and provides the air leaving the dispenser (4) to be delivered to the dehumidifying unit (6).
  • the delivery of air from the tub (3) to the dehumidifying unit (6) is prevented by means of the first valve (10).
  • the air sucked by the fan (8) from the dispenser (4) is delivered to the dehumidifying unit (6) by passing through the first suction channel (109).
  • the washing machine (1) comprises a second suction channel (209) with one end connected to the tub (3), that extends from the tub (3) towards the dehumidifying unit (6) and that enables the air leaving the tub (3) to be delivered to the dehumidifying unit (6).
