Definitions

  • the present invention relates to a heat pump laundry dryer.
  • the humid air condensing on the evaporator fins trickles down as water droplets due to the effect of the gravity and these droplets accumulate in the drain channel between the evaporator and the condenser.
  • the air passing over the evaporator gets humid again by contacting the water in the drain channel and causes the condenser to get wet and its heating performance to decrease.
  • JP2004240737 relates to a heat pump laundry dryer, the drying performance of which is improved.
  • the laundry dryer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a ventilation duct wherein the processing air cycle is realized and an evaporator and a condenser placed into the said channel and the humid air condensing at the evaporator trickles down from the evaporator as water droplets and these droplets accumulate in the drain channel extending between the evaporator and the condenser.
  • the laundry dryer furthermore comprises a guiding means that extends from the condenser towards the evaporator with a downward inclination by at least partially covering the drain channel, that prevents the air coming from the evaporator from entering into the drain channel and that, at the same time, guides the condensation water scattered from the evaporator due to the effect of the airflow, towards the drain channel without entering into the condenser.
  • the laundry dryer comprises a conduit arranged between the guiding means and the evaporator, that provides the condensation water guided downward by the guiding means due to its inclination, to flow into the drain channel.
  • the guiding means extends on the drain channel, between the condenser and the conduit.
  • the guiding means arranged between the condenser and the evaporator so as to cover the drain channel prevents the processing air coming from the evaporator from being humidified and guides it to the condenser, and, thanks to its downward inclined shape, prevents the condensate water that is scattered from the evaporator towards the condenser as droplets with the airflow and that falls downwards through the gap between the evaporator and the condenser with the effect of the gravity, from moving towards the condenser and thus prevents the condenser from getting wet, increasing the heating efficiency of the condenser.
  • the heat pump laundry dryer (1) comprises a drum (2) wherein the laundry to be dried is placed, a ventilation duct (3) wherein the processing air (drying air) cycle is realized, a fan (4) providing the circulation of the processing air, a compressor (5) providing the refrigerant cycle, an evaporator (6) placed into the ventilation duct (3), that condenses the humid processing air, a condenser (7) placed into the ventilation duct (3), that heats the processing air dehumidified at the evaporator (6) and a pump (8) providing the condensate water to be discharged.
  • the laundry dryer (1) of the present invention comprises a drain channel (9) that extends between the evaporator (6) and the condenser (7) and that provides the condensate water coming from the evaporator (6) to be delivered to the pump (8) in order to be discharged and a guiding means (10) that extends from the condenser (7) towards the evaporator (6) by at least partially covering the drain channel (9), that prevents the air coming from the evaporator (6) from entering into the drain channel (9) and guides it to the condenser (7) and that prevents the condensate water coming from the evaporator (6) due to the effect of the processing air from entering into the condenser (7) and guides it to the drain channel (9).
  • the processing air humidified by passing over the laundry in the drum (2) is passed over the evaporator (6) and the condenser (7) in the ventilation duct (3).
  • the evaporator (6) condenses and dehumidifies the processing air, and the condenser (7) heats the dehumidified processing air coming from the evaporator (6).
  • the processing air coming from the evaporator (6) passes over the drain channel (9) located between the condenser (7) and the evaporator (6), and the guiding means (10) placed onto the drain channel (9) prevents the processing air from contacting the water accumulating in the drain channel (9) and provides it to be guided to the condenser (7) without being humidified.
  • the guiding means (10) separately guides the processing air and the condensate water coming from the evaporator (6), thus the heating efficiency is increased by preventing the condenser (7) from getting wet.
  • the laundry dryer (1) furthermore, comprises a conduit (11) arranged between the guiding means (10) and the evaporator (6), that provides the condensate water coming from the evaporator (6) and guided by the guiding means (10) to flow into the drain channel (9).
  • the guiding means (10) extends from the condenser (7) towards the evaporator (6), between the condenser (7) and the conduit (11) with a downwards inclination ( Figure 1 , Figure 2 ).
  • the condensate water moving from the evaporator (6) towards the condenser (7) by passing over the conduit (11) without flowing downwards through the conduit (11) due to the effect of the processing air is provided to move backwards due to the effect of the guiding means (10) inclined in a direction opposite to the moving direction of the water and to flow from the conduit (11) into the drain channel (9).
  • the guiding means (10) is L-shaped, arranged in the ventilation duct (3), at the lower part of the condenser (7); and the parts of the guiding means (10) that are inclined, meaning the parts that guide the air and the water protrude outwards from the lower edges of the condenser (7) ( Figure 3 ).
  • the guiding means (10) serves as a supporting means that maintains the position of the condenser (7) in the ventilation duct (3).
