Definitions

  • the present invention relates to a laundry dryer comprising a spraying device.
  • the heated air is directed into the drum containing the laundry to be dried and is sucked to be redirected into the heating cycle.
  • particles such as fiber, lint etc. accumulate in the air circulation duct and cause the air circulation duct to be clogged.
  • spraying devices are placed on the air circulation duct. The position and the placement of the spraying devices are important for the cleaning of the said particles such as lint, fiber, etc.
  • the spraying devices are not effective to provide the desired water flow on the heat exchanger by themselves.
  • the aim of the present invention is the realization of a laundry dryer, the drying effectiveness of which is increased.
  • 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 heat exchanger that is disposed in the air circulation duct and that provides the heating of the processing air (PA) blown onto the laundry, and a spraying device that is disposed in the air circulation duct and that sprays water onto particles such as lint, fiber, etc. accumulating on the heat exchanger, thus providing the cleaning of these particles.
  • PA processing air
  • the laundry dryer of the present invention furthermore comprises a guiding member that is disposed at the upper portion of the heat exchanger, that extends outwards from the heat exchanger and enables the water sprayed from the spraying device and hitting thereon to be guided onto the heat exchanger. Thanks to its position, the spraying device sprays water upwards so as to hit the guiding member remaining above the spraying device.
  • the spraying device is disposed on the air circulation duct so as to be aligned with the base of the heat exchanger.
  • the spraying device sprays water upwards so as to hit the guiding member.
  • the guiding member is disposed at the upper portion of the surface of the heat exchanger contacting the processing air (PA) first and extends outwards from the heat exchanger in a direction opposite to the flow direction of the processing air (PA).
  • the spraying device sprays water onto the guiding member in an angular manner and the guiding member changes direction with the impact of the water sprayed thereon in an angular manner and enables the said water to be guided onto the heat exchanger surface.
  • the spraying device is disposed on the air circulation duct, in front of the heat exchanger so that a distance remains between the heat exchanger and the spraying device.
  • the guiding member has an inclined surface whereon the water sprayed from the spraying device contacts.
  • the guiding member has a hollow semi-circular cross-section.

  • the water condensing in the processing air (PA) condensed by the heat exchanger (5) is delivered to a chamber located in the vicinity of the heat exchanger (5).
  • the water accumulating in the chamber is transferred to the spraying device (6) by means of a transfer means.
  • the spraying device (6) sprays water onto the guiding member (7) situated thereabove and the water hitting the guiding member (7) makes a downward movement to sweep the surface of the heat exchanger (5) from end to end and enables the particles such as lint, fiber, etc. sticking onto the heat exchanger (5) to be removed from the heat exchanger (5).
