摘要:
A top (119) is adapted to match and close from above a cabinet (110) of a laundry drying appliance (100). The top is formed as a ready-to-mount part ready to be mounted to the cabinet and forms a moisture condensing module for dehydrating drying air used to dry laundry within a drying drum of the laundry drying appliance. The top has a drying air inlet (510), a drying air outlet (515), fluid passageways defined thereinside from said drying air inlet to said drying air outlet for the passage of the drying air to be dehydrated and moisture condensing means arranged inside the fluid passageways.
