FIG 1 illustrates a schematic sectional side view of alaundry dryer 10 with a heat pump system according to a preferred embodiment of the present invention. - The
laundry dryer 10 includes a casing 27 (only partially represented in the enclosed drawings) containing a rotatable laundry drum 12 (in which the laundry can be loaded) and provided with an access opening 14 for accessing the internal of thedrum 12; theaccess opening 14 may be closed by a door, not illustrated in the enclosed figures, preferably hinged to thecasing 27. Advantageously thelaundry drum 12 is rotatable around a substantially horizontal axis. Said axis extends from the front side to the rear side of thelaundry dryer 10. Theaccess opening 14 is arranged at the front side of thelaundry dryer 10. - The heat pump system includes an air stream circuit formed preferably as a closed loop. The air stream circuit comprises the
laundry drum 12, anevaporator 18 and acondenser 20. Thearrows 16 inFIG 1 schematically represent the air stream. Theair stream 16 flows in thelaundry drum 12 from the rear side to the front side of saidlaundry drum 12, removing moisture from the laundry (not illustrated), contained in saiddrum 12. Thus, theair stream 16 arrives at theaccess opening 14. Then, theair stream 16 flows from the access opening 14 downwards to a bottom of thelaundry dryer 10, where achannel 28 is provided for the flowing of thisair stream 16. Advantageously thecondenser 20 is placed inside thechannel 28. Inside thechannel 28 in the bottom of the dryer, theair stream 16 flows, at least partially, rearwards (i.e. towards the rear of the dryer). At last, theair stream 16 flows upwards in the rear portion of thelaundry dryer 10 into the rear side of thelaundry drum 12 again. - Between the access opening 14 and the
channel 28 provided in the bottom of the dryer, theair stream 16 advantageously passes amain filter element 22, preferably also anadditional filter element 24, preferably also aprotection grid 26, and theevaporator 18. - The following description refs to an embodiment in which the
laundry dryer 10 comprises, in addition to themain filter element 22 and theevaporator 18, also theadditional filter element 24 and theprotection grid 26; however it is clear that also an embodiment in which theadditional filter element 24 and theprotection grid 26 are not provided is comprised in the invention. - Advantageously, the
air stream 16 passes themain filter element 22, theadditional filter element 24 and the protection grid 26 (if provided) in a vertical direction. Advantageously a bigger part of theair stream 16 changes its direction inside the evaporator 18 from vertical to horizontal. A smaller part of theair stream 16 leaves theevaporator 18 in the vertical direction. Alternatively, theair stream 16 changes its direction below the evaporator 18 from vertical to horizontal. Theair stream 16 passes thecondenser 20 in the bottom of thelaundry dryer 10. Advantageously, themain filter element 22, the additional filter element 24 (if provided), the protection grid 26 (if provided) and theevaporator 18 are arranged on top of each other in the lower front portion of thelaundry dryer 10. Further, themain filter element 22, the additional filter element 24 (if provided), the protection grid 26 (if provided) are advantageously arranged at least partially in correspondence of a bottom region of the access opening 14, and they extends below the latter, inside thecasing 27. Advantageously theevaporator 18 is arranged below theaccess opening 14. - The geometric properties of the
main filter element 22, the additional filter element 24 (if provided), the protection grid 26 (if provided) and theevaporator 18 are adapted to a front wall of thelaundry dryer 10 below theaccess opening 14. Thus, themain filter element 22, the additional filter element 24 (if provided) and the protection grid 26 (if provided) can be easily removed from access opening 14 of thelaundry dryer 10 by an upward motion. Themain filter element 22, the additional filter element 24 (if provided) and the protection grid 26 (if provided) can be cleaned outside thelaundry dryer 10. Further, the absence of themain filter element 22, the additional filter element 24 (if provided) and the protection grid 26 (if provided) allows an access to the inlet side of theevaporator 18, so that the latter may be cleaned directly from the access opening 14, for example by using a vacuum cleaner. -
FIG 2 illustrates a schematic perspective view of thelaundry dryer 10 with the heat pump system according to the preferred embodiment of the present invention. -
FIG 2 clarifies the arrangement of theevaporator 18 below the access opening 14 of thelaundry dryer 10. InFIG 2 themain filter element 22, theadditional filter element 24 and theprotection grid 26 have been removed advantageously by an upward motion. This allows the access to the inlet side of the evaporator 18 from theaccess opening 14. The total inlet side of theevaporator 18 can be easily cleaned. -
FIG 3 illustrates a detailed perspective view of the access opening 14 of thelaundry dryer 10 with the heat pump system according to the preferred embodiment of the present invention.FIG 3 clarifies that substantially the total inlet side of theevaporator 18 is accessible, when a door (not illustrated) of the access opening 14 has been opened. - The
laundry dryer 10 according to the present invention requires no additional door to thefilter elements protection grid 26 and theevaporator 18. This reduces the complexity of thelaundry dryer 10. The inlet side of theevaporator 18 can be easily directly cleaned for example by a vacuum cleaner, so as to obtain an effective cleaning. - There is more space in the air stream circuit downstream the
condenser 20 improving the flow of the air stream. This allows for example the arrangement of air deflectors in the air stream circuit in order to optimize the flow of the air stream. The efficiency of water condensation is improved, so that possible leakages from a door plinth in the case of a bad seal are eliminated or at least reduced.
