MACHINE FUNCTION
Drying Overview
These models are freestanding tumble dryers with a full width metal door.
Reversible hinges allow the door to be hung on either the left or right hand side of the front panel. The
appliance is supplied with the door hung on the left hand side of the cabinet.
The facia moulding across the top of the front panel houses the machine user controls and water
container.
The drum is supported at the front by 2 drum support wheels or 4 bearing pads (depending on model)
mounted on the front air duct and a single bearing at the rear located in the rear panel. A shaft fixed
to the rear of the drum runs in the rear bearing. The drum is driven by a belt which passes around its
periphery and onto the shaft of a motor secured to the base of the machine. The belt is tensioned by
a pulley mounted to the motor.
The motor also drives two impellers
(rotors), fixed to each end of its shaft.
The front impeller draws cold air into
the machine, while the rear impeller
recirculates drying air.
The addition of heat to the
recirculating air is provided by a
heating unit attached to the rear
panel, enabling the air to hold
moisture when in contact with the wet
load, thus causing it to dry. As the
warm recirculating air passes through
the drum, it collects lint as well as
moisture. To prevent the lint from
blocking the heat exchanger
(condenser), the air is passed through
a filter located in the front air duct.
The filter unit is positioned so as to be easily removable for cleaning by the user. After passing through
the filter, the circulating air is ducted through passageways in a heat exchanger (condenser) located
in a housing on the base of the machine. Cold air is drawn into the machine and flows across the heat
exchanger passageways. This cold air is not mixed with the warm, damp recirculating air. See the
condenser airflow picture.
This has the effect of reducing the circulating air temperature, causing it to give up its moisture.
(Cold air holds less moisture than hot air.) The now warm cooling air is exhausted through slots in the
rear of the dryer.The moisture removed from the recirculating air is pumped to a removable container
mounted in the left hand side of the console. The user can easily withdraw the container to dispose
of the collected condensed water. There is no requirement for venting to atmosphere on this dryer.
