The inner tub has numerous holes. The centrifugal force pulls out wash water from the
clothes and makes it move through these holes to the outer tub which stationary. The water
gets pumped out from here through the drain tube. After the wash water has left, the inner tub is
again filled with clean water. Agitator again works to tumble the clothing. This is the second
cycle and is called the rinse cycle. The aim of this cycle is to discharge the detergent particles
trapped in the washed fabric. On completion of rinsing, the machine again drains out water.
Once the water has been drained out, another electric motor comes to play. It agitates the
inner tub at an extremely high speed. The centripetal force spins out remaining water from the
fabric and expels it through the drain tube. This is a timed process. The clothing gets reduced
from saturated to merely wet. This is the third cycle, called as spin cycle, which is is to remove
out as much water as possible from the wet clothes. In all the steps, draining is carried out by
the drain tubes. The cleaning of the fabric is done and it is ready to dry.
12.16 Construction and Working of Front loading washing machine:
Fig. 12.11 - Inside a front loading
washing machine
The construction and working of front loading
washing machine is similar to top loading except that it
consists of a cylindrical drum, instead of the long agitator
as shown in Fig.12.11. In this type, washing is carried
out by tumbling the clothes with the help of a simple
cylindrical drum called as tumbler washing tub as shown
in Fig.12.12
The disc contains blades, called as agitating vanes
or paddle, on its upper side. The rotation of the disc and
the blades produce strong currents within the water and
the rubbing of clothes that helps in removing the dirt from
clothes. As Front loaders spin and allow gravity to do
the work as the clothes tumble and bounce, so do not
have agitators.
Note: Some models of washing machines, either semi or fully automatic, having heater in
the bottom of washing tub. The heater is generally immersion rod type which is permanently
fixed in the bottom the washing machine as shown in Fig.12.13. The purpose is to produce
warm water for loosening stripper dirt particles of the clothes for quick cleaning.
