Definitions

  • the present invention relates to a heat pump laundry dryer.
  • the heat pump used for drying the laundry is composed of heat exchangers named as evaporator and condenser.
  • the laundry-drying process is performed by passing hot and dry air over the laundry. Humid air leaving the laundry leaves its moisture while passing over the evaporator that works as the condenser and warms while passing over the condenser that works as the heater. The air that leaves its moisture and warms up is sent onto the laundry throughout the drying cycle.
  • 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 lower water collection chamber under the evaporator.
  • the condensed water in the lower water collection chamber is delivered to the water pumping chamber to be discharged by means of the water flow channel. Meanwhile, the air flow generated by the effect of the fan that maintain the cycling of the process air prevents the water from flowing into the water pumping chamber and cause water accumulation at the region of the flow channel.
  • the collected water humidifies the process air and decreases the drying performance of the dryer and cause generation of undesired bad odors.
  • a laundry dryer is explained, wherein the discharge of the water condensing in the evaporator is facilitated.
  • a dryer having a flow channel and a guiding member that enables the process air to be directed on the flow channel.
  • the aim of the present invention is the realization of a dryer wherein the drying efficiency is increased and generation of undesired bad odors is prevented by facilitating the discharge of the condensate water.
  • the dryer realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a flow channel having at least one barrier that prevents the accumulation of the condensed water in the lower water collection chamber and the water flow in reverse direction from the water pumping chamber towards the lower water collection chamber generated by the effect of the fan.
  • the dryer comprises the inclined flow channel so as to facilitate the flow of the condensed water.
  • the lower water collection chamber is located at a position higher than the water pumping chamber and the inclined base of the flow channel forms a barrier that prevents the reverse flow of water.
  • the flow channel comprises more than one barrier in cascade form to prevent the water flow in the reverse direction.
  • the barriers in cascade form force is exerted on the water tending to flow in the reverse direction due to the air flow over the flow channel, and flow in the reverse direction is prevented.
  • the lower water collection chamber is at the same level with the water pumping chamber.
  • more than one barrier configured as a zipper so as to face each other is used on the side walls of the flow channel. By the barriers, the water over the flow channel is directed and prevented from accumulating.
  • the barriers are in zipper form and face each other angularly.
  • the barriers in zipper form By means of the barriers in zipper form, the water is enabled to flow in a zigzag manner and the effect of the air flow on the water is decreased.
  • the dryer of the present invention can be a laundry dryer or a laundry washer/dryer.
  • the condensed water is prevented from accumulating inside the dryer and enabled to be almost entirely discharged.
  • the barrier that forms the base of the inclined flow channel between the lower water collection chamber and the water pumping chamber a resistance is formed in a direction opposite to the resistance formed by the air flow originating from the fan and the water is enabled to flow towards the water pumping chamber.
  • the barriers provided on the flow channel and in cascade form the water is prevented from flowing in the reverse direction.
  • the said problem is solved by using barriers disposed on the flow channel in the dryers where the lower water collection chamber and the water pumping chamber are at the same horizontal level.
