    摘要： The invention relates to a method for controlling a heat pump laundry drying machine comprising a rotatable drum where textile is introduced and treated with a process air (A), said drum being driven in two rotation directions; a heat pump system (44) having a refrigerant circuit (40) in which a refrigerant can flow, said refrigerant circuit including a first heat exchanger (32) where the refrigerant is cooled off, a second heat exchanger (34) where the refrigerant is heated up, a compressor (36) to pressurize and circulate the refrigerant through the refrigerant circuit (40); said first and/or second heat exchanger being apt to perform heat exchange between said refrigerant flowing in said refrigerant circuit and said process air; a cooling device (42) for cooling a component (36) of the heat pump system;- a selector adapted to select alternatively at least an outdoor drying cycle for drying outdoor textiles which have a waterproof and breathable thin film material with a micro-porous structure, and at least an additional drying cycle for drying other types of textiles, wherein the outdoor drying cycle includes an outdoor main drying phase having settings for a frequency of reversion of rotations of the drum and for the heat pump operation and the additional drying cycle comprises an additional main drying phase having settings for a frequency of reversion of rotations of the drum and for the heat pump operation;wherein the method comprises: - selecting and starting the outdoor drying cycle, and entering the outdoor main drying phase, wherein the outdoor main drying phase includes an outdoor first sub-phase (S2) and an outdoor second sub-phase (S3); - reversing the rotation of the drum (16) in the outdoor first sub-phase at a frequency (F1) lower than a frequency in the additional main drying phase; - entering the outdoor second sub-phase when the humidity of said outdoor textile is equal or below a first threshold; - in the second sub-phase, reversing the rotation of the drum at a frequency (F2) lower than the drum rotation reversal frequency (F1) operated in the outdoor first sub-phase; and operating one or more of the following: €¢ increasing a flow rate of the process air in the drum with respect to a flow rate in the outdoor first sub-phase and with respect to a flow rate in the additional main drying phase; €¢ increasing a velocity of and/or a power supply to a motor (67) of the compressor (36) with respect to a velocity of and/or a power supply to a motor of the compressor in the outdoor first sub-phase and with respect to a velocity of and/or a power supply to a motor of the compressor in the additional main drying phase; €¢ increasing a temperature at which the cooling device (42) is activated/deactivated with respect to a temperature at which the cooling device is activated/deactivated in the outdoor first sub-phase and with respect to a temperature at which the cooling device is activated/deactivated in the additional main drying phase.

    摘要： The invention relates to a laundry drying apparatus, in particular dryer (2), comprising a cabinet and a laundry storing compartment arranged within the cabinet for receiving laundry to be dried. An air channel is arranged within the cabinet and adapted to guide drying air from at least one air outlet of the laundry storing compartment to at least one air inlet of the laundry storing compartment. A lint collecting component is arranged in the air channel exposed to the drying air and being receptive for the deposition of lint carried by the drying air. A wet cleaning unit has a nozzle for supplying liquid for washing lint from the lint collecting component. A liquid collector is adapted to collect liquid supplied by the wet cleaning unit for washing the lint collecting component. A liquid pump (36) has a motor (68), a liquid conveying element (70) driven by the motor (68) and a conveying element housing (76) which is fluidly connected to the liquid collector, wherein the liquid pump (36) is adapted to drain the liquid collected in the liquid collector. The conveying element housing (76) of the liquid pump (36) comprises a removable unit (82) forming a section of the conveying element housing (76). The removable unit (82) is adapted to be manually removed by a user. When the removable unit (82) is removed from the liquid pump (36), at least a portion of the conveying element (70) or the inner volume (90) of the conveying element housing (76) is exposed for user maintenance.
