Definitions

  • the present invention relates to a laundry dryer comprising a filter that holds particles like fiber, lint, etc. in the drying air.
  • the drying process is provided by the interaction of the cooling air and the process air that do not directly contact one another.
  • the process air is heated by a heater and directed into the drum, contacts and dehumidifies the damp laundry and then is transferred to a condenser to be dehumidified.
  • the cooling air is delivered onto the condenser by means of a fan and thus, the moisture in the process air is enabled to be condensed by the condenser being cooled.
  • the process air is heated by the heater and is delivered into the drum with high temperature and low relative humidity rate and is involved in the drying cycle again.
  • the aim of the present invention is the realization of a laundry dryer wherein the filter is effectively cleaned and the drying effectiveness 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 body; a drum wherein the laundry to be dried is placed; an air circulation duct that provides delivery of process air onto the laundry inside the drum; a filter that is disposed in the air circulation duct and that holds the fibers and lint in the process air blown onto the laundry; a condenser that is disposed in the air circulation duct and that provides the condensation of the process air passing thereover; a receptacle that is disposed under the condenser and wherein the water droplets formed on the condenser surface are collected; a discharge line whereby the water collected in the receptacle is carried to the filter by a discharge pump, and a level sensor that is disposed in the receptacle and that detects the level of the water collected in the receptacle.
  • the laundry dryer of the present invention comprises a control unit that controls the discharge pump depending on the data received from the level sensor and that enables some of the water in the receptacle to be stored and used in the next drying cycle.
  • the control unit operates the discharge pump and prevents the water collected in the receptacle from overflowing outside.
  • the control unit interrupts the energy delivered to the discharge pump and enables the discharge pump to be stopped.
  • the control unit when the level detected by the level sensor reaches a limit level predetermined by the producer, the control unit enables the discharge pump to be stopped and the water left in the receptacle to be stored for using in the next drying cycle.
  • the discharge pump is stopped when the water level in the receptacle is at a limit level that is higher than the lower critical level predetermined by the producer.
  • the control unit turns off the discharge pump before all the water in the receptacle is used and enables all the water under the limit level to be stored in the receptacle.
  • the control unit does not operate the discharge pump again until the drying cycle is completed and thus enables the water left to be stored until the next drying cycle.
  • the water stored in the receptacle under the limit level in the previous drying cycle is used for cleaning the filter at the start of the drying cycle until condensation begins in the condenser.
  • the water left from the previous drying cycle is used so that the receptacle is prevented from being dry and accordingly the filter is enabled to be cleaned effectively.
  • the laundry dryer comprises - an airing step wherein air is delivered onto the laundry for removing the odors thereon and
  • control unit ends the airing step and starts the drying step depending on the data received from the level sensor.
  • the control unit stops the discharge pump when the water level in the receptacle decreases to the lower critical level and starts the drying step after ending the airing step.
  • a laundry dryer is realized wherein the filter is effectively washed during the drying cycle by storing some of the water condensed in the condenser to be used in the next drying cycle.
  • the laundry dryer (1) comprises a body (2); a drum (3) wherein the laundry to be dried is placed; an air circulation duct (4) enabling the process air (PA) to be delivered onto the laundry inside the drum (3); a filter (5) that is disposed in the air circulation duct (4) and that holds the particles like fiber, lint etc.
  • PA process air
  • a condenser (6) that is disposed in the air circulation duct (4) and that enables the process air (PA) passing thereover to be condensed; a receptacle (7) that is disposed under the condenser (6) and wherein the water droplets forming on the surface of the condenser (6) accumulate; a discharge line (9) that enables the water collected in the receptacle (7) to be carried to the filter (5) by means of a discharge pump (8), and a level sensor (10) that is disposed in the receptacle (7) and that detects the level of the water accumulated in the receptacle (7) ( Figure 1 and Figure 2 ).
  • the laundry dryer (1) of the present invention comprises a control unit (11) that controls the discharge pump (8) depending on the data received from the level sensor (10) and that enables some of the water in the receptacle (7) to be stored and used in the next drying cycle.
  • the control unit (11) enables the discharge pump (8) to be operated such that the water level inside the receptacle (7) is between an upper critical level and a lower critical level predetermined by the producer.
  • the dryness rate of the laundry increases in the course of time and therefore the amount of water condensed at the condenser (6) decreases.
  • the level of water collected in the receptacle (7) also decreases in the course of time.
  • the control unit (11) stops the discharge pump (8), thus preventing all the water in the receptacle (7) to be used and enables some of the water in the receptacle (7) to be stored.
  • Particles such as fiber, lint and fluff coming off the laundry and carried in the process air (PA) that circulates in the air circulation duct (4) disposed in the body (2) during the operation of the laundry dryer (1) accumulate in the course of time on the filter (5) disposed in front of the condenser (6).
  • the process air (PA) reaches the filter (5) before the condenser (6).
  • the water in the process air (PA) condensed by the condenser (6) accumulates in the receptacle (7) disposed under the condenser (6).
  • the water accumulated in the receptacle (7) is delivered to the filter (5) by being transferred to the discharge line (9) by means of a discharge pump (8) and the fibers and lint collected on the filter (5) are enabled to be swept.
  • the control unit (11) when the level detected by the level sensor (10) reaches a limit level (H lim ) predetermined by the producer, the control unit (11) enables the discharge pump (8) to be stopped and the water left in the receptacle (7) to be stored for using in the next drying cycle.
  • the amount of water condensed on the condenser (6) changes depending on the amount of moisture removed from the laundry. Since water is not present in the receptacle (7) at the start of the drying cycle, delivery of water to the filter (5) and cleaning of the filter (5) cannot be performed until the water is collected in the receptacle (7).
  • the discharge pump (8) is stopped after the water level in the receptacle (7) reaches the limit level (H lim ), and the water below the limit level (H lim ) is stored in the receptacle (7) to be used in the next drying cycle.
  • the control unit (11) operates the discharge pump (8) again and stops the discharge pump (8) once more when the water level in the receptacle (7) goes down to the limit level (H lim ) again.
  • the control unit (11) enables the discharge pump (8) to be operated and stopped intermittently so that the water level in the receptacle (7) does not rise above the limit level (H lim ).
  • the water left from the previous drying cycle that is below the limit level (H lim ) is carried from the receptacle (7) to the filter (5) for the aim of cleaning the filter (5).
  • the laundry dryer (1) comprises
  • the control unit (11) ends the airing step and starts the drying step depending on the data received from the level sensor (10).
  • the airing step is continued for a time period predetermined by the producer. No condensation occurs in the condenser (6) during the airing step, the water collected in the receptacle (7) is delivered to the filter (5) by means of the discharge pump (8) for the aim of cleaning the filter (5) and thus the level of the water left in the receptacle (7) decreases gradually.
  • the control unit (11) controls the amount of water left in the receptacle (7) by means of the level sensor (10) and when the water collected in the receptacle (7) is finished, ends the airing step and enables the drying step to start.
  • the heater is operated and the moisture removed from the laundry by means of the hot process air (PA) delivered to the drum (3) is condensed in the condenser (6) and collected in the receptacle (7).
  • PA hot process air
  • the laundry dryer (1) of the present invention some of the water collected in the receptacle (7) is stored to be delivered to the filter (5) in the next drying cycle, thus the fibers and lint collected on the filter (5) are enabled to be cleaned effectively during the drying cycle.
