INTRODUCTIONA 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.

HISTORYThe 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.

TYPES OF WASHING MACHINEAccording to Laundromat or gates available

for loading the washing machines are generally classified into 2 (two) types.

Top-loading Front-loading

TOP-LOADINGIn a top-loading washer, water circulates primarily along the poloidal axis & vertical axis during the wash cycle.Poloidal axis is shown by red arrowVertical 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

FRONT-LOADINGIn 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.

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

WASH CYCLES

Generally wash cycle contains three main activities:

Washing Rinsing Spinning

GENERAL PARTS SHAFTGEARFLYWHEELBEARINGFINS DRUMMEMBRANE

PARTSSHAFT 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.

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.

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

MODEL

WORKING OF PEDDLING WASHING MACHINEThe 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 applying 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.

JUSTIFICATIONEFFICIENT  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.

 

EASY TO BUILD AND MAINTAIN  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.

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.

ANALYSIS

CLEANING Machine-washed clothes must be as clean as those hand-washed for 5 minutes

[color]  GENTLENESS Must wear clothes at slower rate than hand-washing [hole/tear growth]  CAPACITY Minimum 3kg of clothes/load – should be easy to re-size.23  WATER Effective washing must occur in soft and hard water at temperatures from 70-120F  WATER USAGE Maximum 5L water / 1kg clothes  ACTIVE PEDALLING TIME FOR EFFECTIVE WASHING Maximum 20 minutes each for wash and rinse cycles

TOTAL OPERATION TIME Maximum 1 hour, including fetching water, filling, washing, draining, and cleaning

machine  POWER Maximum 60W (comfortable level of human-power output)  LIFETIME OF STRUCTURE 7-8 years, assuming daily use  MANUFACTURING CAPITAL COST 12000 Rs. (welder, metal cutter, shop tools)  MANUFACTURING LOCATION Berhampur, odisha•  MATERIALS Local (shaft, bearing, weld able metals, galvanized drum, cycle parts, etc.)  DIMENSION 4 Foot long and 1.3 foot width  WEIGHT Maximum 20kg or 30kg

CONCLUSIONFrom 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.
