Design and Fabrication of Pedal Powered Washing Machine | Engineering Project

Abstract

The pedal operated washing machine is the machine best option for the areas where the availability of electricity is the main concern. To run the washing machine electricity is needed and in the areas having electricity problem, it is difficult to run these machines. Hence, in order to overcome this problem, we have decided to design a pedal-powered washing machine that will be operated manually. This machine is simple, lightweight, portable and easy to operate. Pedal power is the transfer of energy from the human sources mostly by the use of a foot pedal and crank system.

Introduction

Washing machines are one of the most useful devices in households today. A washing machine is basically a machine designed to wash or clean laundries such as towels, clothing, and sheets. Generally, washing machines are powered by electrical energy. This project intends to design and fabricate a washing machine that uses our energy instead. All washing machines work by using mechanical energy, chemical action, and thermal energy. Mechanical energy is transmitted to the clothes load by the rotation of the agitator or by the whirling action of the drum. In this project, the rotation of the drum or agitator is caused by the rotation of the pedals. The temperature of the wash bath supplies the thermal energy. The chemical energy is supplied by the detergent. Pedal power involves transferring power from a human source by means of foot pedals and a crank system.

Problem Statement

Design a washing machine that will run on human power, will be cost-effective and have less maintenance.

Construction of Pedal operated washing machine

The construction of the pedal-operated washing machine is shown in the figure.

Pedal Powered Washing Machine

Pedal-powered washing machine consists of the following components:
  • Pedal
  • Chain
  • Gear/ front sprocket
  • Flywheel/ rear sprocket
  • Shaft
  • Outer drum
  • Inner drum

Working of Pedal-powered washing machine

The chain drive system is attached to the user's end. The chain drive system consists of the front sprocket, rear sprocket, and a chain. The pedal is attached to the front sprocket, which drives the rear sprocket with the help of pedal through a human source.
The shaft is attached to the inner drum by means of rivets. When the shaft rotates, the drum also rotates. The inner drum is the drum that holds the clothes to be washed. It has rectangular bars fitted on its walls, these help in lifting the clothes during the wash cycle. It has a door at the top. The outer drum contains water.
To operate the pedal-powered washing machine one has to follow the following steps: 
  • Open the outer and inner drum doors.
  • Put the clothes in the inner drum and close the inner door.
  • Pour about 5 to 10 liters of water and add detergent.
  • Close the outer door and sit on a comfortable chair.
  • Begin to cycle starting slowly and increasing the pace. Pedal for about 15-20 minutes.
  • Remove the soapy water by opening the drainage screw at the bottom of the outer drum. You can add rinsing water and pedal for a short time. Remove the water. Drying will require a faster pedaling rate. The heat in the drum will also help dry the clothes.
  • Now remove the clothes from the machine. The machine has to be maintained at regular intervals. A preventative type of maintenance every 5 years is more suitable. The components that require replacement are the sprocket, gears and the chain. The chain has to be greased regularly

Advantages

  • The pedal-powered washing machine is cost-effective.
  • It is eco-friendly.
  • It can be easily moved to another location.
  • It requires less maintenance.

Disadvantages

  • Human effort is needed.
  • The structure is complex.
