Design and fabrication of solar and pedal powered washing machine
Project Area of Specialization Mechanical EngineeringProject SummaryA 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 washing machine project aims to design and fabricate a washing machine which uses human energy and solar energy. Make the connection of solar panel with batteries and with the machine during sunny weather we utilize the sun energy into useful work. And through pedal the Mechanical energy is transmitted to the clothes load by the rotation of the agitator or by the whirling action of the drum. In this solar and pedal powered washing machine project, the rotation of the drum or agitator is caused by the rotation motion of the pedals. Pedal power involves transferring power from a human source by means of foot pedals and a crank system. The proposed machine does not use electricity thus will be suitable for places where electricity is not available.
To devise more than one mechanism i.e. solar and pedal powered for washing
To device a Washing Machine that will focus on the health care of females.
To generates up to 110 watt through pedaling and provides a smooth wash.
Project will be implemented through stepwise sophisticated method. First of all study related to pedaling rate, gear mechanism and solar panel will be carried out. Next, CAD model will be developed through Solid Works which will be followed by the fabrication of the machine. The project will be ended by performing cost analysis.
Benefits of the Project? We can use this machine in rural areas where electric powered machines are not working because there
is no electricity.
? It save the time because Women are mainly the ones burdened by the washing of clothes and can
spend an entire day washing clothes.
? Protects hands and clothes because Washing by hands involves scrubbing, beating, soaking and rinsing
the dirty clothes which is a laborious and time consuming task.
The chain drive system will be 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 will 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.
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
