This document describes a pedal-powered washing machine designed by a group of mechanical engineering students. It consists of a drum mounted horizontally inside an outer tub. Clothes are loaded through a front door. Turning pedals powers a chain drive that rotates the drum, agitating clothes in water to clean them. It is intended for rural areas as an efficient alternative to manual washing that uses locally available recycled bicycle parts, conserving water and detergent. Analysis shows it can effectively clean clothes with minimal human power in under an hour.

3. INTRODUCTION
 A washing machine (laundry machine, clothes
washer, or washer) is a machine used to
wash laundry, such as clothing and sheets. The
term is mostly applied to machines that
use water as opposed to dry cleaning (which uses
alternative cleaning fluids, and is performed by
specialist businesses) or ultrasonic cleaners.

4. HISTORY
The use of machine for laundry process is not a new
thing, it started since 1691.
But the rotary type washing machine is designed by
Hamilton Smith in 1858.
As electricity is not available until last of 1930, some
early washing machines are operated by low-speed,
single cylinder hit-and-miss gasoline engine.
Near about at the age of 19th and 20th century washing
machines are widely used for home and commercial
cleaning service.
Bendix Corporation introduced first automatic front
loaded washing machine in 1937.

5. TYPES OF WASHING MACHINE
According to Laundromat or gates available for
loading the washing machines are generally
classified into 2 (two) types.
Top-loading
 Front-loading

6. TOP-LOADING
In a top-loading washer, water
circulates primarily along the poloidal
axis & vertical axis during the wash
cycle.
Poloidal axis is shown by red arrow
Vertical axis is shown by blue arrow
This design places the clothes in
vertically mounted perforated basket
i.e. contained within a water-retaining
tub. Clothes are loaded through the top
of the machine, which is usually but not
always covered with hinged door.
TOP-LOADING TYPE
AUTORUS AXIS

7. FRONT-LOADING
In a front-loading washer,
water circulated in horizontal axis,
agitating is supplied by back-and-forth
rotation of the cylinder and by gravity.
This layout mounts the inner
basket and outer tub horizontally, and
loading is through a door at the front of
the machine. The door is often but not
always contain transparent window.
Because less water required,
front loaders typically use less
detergent, and the repeated dropping
and folding action of the tumbling can
easily produce large amount of foam or
suds.

8. COMPARISION
Basis of Comparison Top-loading Front-loading
Efficient cleaning Less efficient Highly efficient
Water usage more water than top-
loader
1/3 to ½ of top-loaders
Spin speed Not to exceed 1400
RPM
Up to 2000 RPM
Cycle length Shorter cycle times Longer cycle times
Wear & abrasion More wear & tear Much less wear & tear
Noise Create more noise Create less noise
Compactness Respectively more area Needs less floor area
Water leakage Less near about no
leakage
More leakage can
possible

9. WASH CYCLES
Generally wash cycle contains three main activities:
 Washing
 Rinsing
 Spinning

10. GENERAL PARTS
SHAFT
GEAR
FLYWHEEL
BEARING
FINS
DRUM
MEMBRANE

11. PARTS
SHAFT
Here we are using a iron-hollow shafting. It is a
main base for the mounting the flywheel.
DRUM
We have used an aluminium drum , which is non
corrosive in nature, these are specially prepared
for this purpose.

12. BEARING
Bearing are used as a mechanical component to
transfer the power and to move a certain part,
and is done by utilizing the small frictional forces
of the bearing, which makes rotates easily
withstanding the force and weight load acting
against them. Bearing house be classified into two
major groups, namely, sliding bearings and rolling
bearings, depending on their friction type. Here
rolling bearing are used.

13. FLYWHEEL
Here we are using a 20 teeth back wheel of the
cycle flywheel. It is attached with the shafting
and another end with the cycle big flywheel by
means of chain drive.
 FINS
We have used plastic shaved modern fins that
are generally used in automated washing machines.
These are corrosion free and are easy and light
weight. These are easily available in shops and are
cheap

15. WORKING OF PEDDLING WASHING MACHINE
The main important thing is how the pedal powered washing machine
works?
Here after manufacture we are starting a working of the peddling
washing machine. First of all open the both the door of the inside and
outside drums. Then put up the cloth in the drum. After put up the cloth
according to requirement put the 5 to 10 liters water and the
washing powder.
Now close the both the door. And sit on the cycle and starting up to ap
plying a pedal with slowly .After 15 to 20 minutes applying the pedal stop
the applying the pedal and see what’s happens. Then removes the inside
water with the help of below pipes in the one doll or other objects.
After removing the water apply the some pedal its gain the heat inside
the drums and its help into the drying the cloth. Then remove the cloth
from the drum.

16. JUSTIFICATION
 EFFICIENT
It is much more efficient to wash clothes using than to
use the manual washing tanks. It’s also requires less energy
when compared to vertical axis washing machines. The
horizontal axis of rotation uses less power because it
rotates continuously without changing directions. The
operator does not need to combat the momentum and drag
forces of a barrel full of water. The operator
does Not need to lean over the washing tank and submerge
her hands in the soapy water. Instead, the operator sits
on the seat and pedals most of the time. She only needs
get up to load the machine, change the water and unload
the machine. This leaves her hands free to work on making
crafts and keeps them out of the harmful detergent.

17.  EASYTO BUILDANDMAINTAIN
Unlike any of the other alternatives, its uses locally
available materials or recycled bicycle parts. It can be
produced in any area that has prevalent bicycle
technology and things like plastic buckets.
Since the parts are widely available, it can serve as a
basis for local entrepreneurs to start
microenterprises which would stimulate the local
economy. Another advantage of using locally available
parts is that easy to repair. It is mechanically simple
enough that any bicycle repair shop would be able to
service the pedal-drive.

18. APPLICATION
 It is very useful into the local rural areas.
 Saving in detergent and the water
 Scale free tub
 Reduced traces of detergent on clothes
 Better wash quality
 Softer clothes
 Easy to operate and the less effect of chemical on the women
hand.
 Exercise is also done with the applying the pedal.

22. CONCLUSION
 From the above project, it can be concluded that the
“peddling washing machine” is a very simple yet very
powerful design of washing cloth which if brought into
application in the rural areas of the developing
countries can aid a lot of plight and the suffering of
the poor peoples who find it very difficult to wash
cloth by means of hand. Thus it is used as a application
keeping in mind the social welfare of the peoples of
the rural areas. Also It is safe in working condition
and hence it does not require any safety guards during
operation. The cost of maintenance is a low and it
 Has a long life.
