Design And Construction Of An Automatic Hand Washing Machine

The unhealthy pattern of washing and drying of hands in various restaurants and places of food selling has prompted the need for this project. We have taken the standard mechanical Hand washing made it a technological engineering wonder of touch-less Hand washing. The machine comprises a housing having a top portion and a bottom portion. The top portion is spherical shaped structure comprising a fluid injection system for injecting water and liquid soap to users’ hands. The bottom portion comprises a box shaped structure. The machine further comprises a wash basin coupled in the interior of said box shaped structure with circular opening under where the used water or liquid soap pass through, an electronic eye for detecting the insertion of hands in said wash basin and a control unit for timing the activation of said water injection. This research work has successfully presented a functional and highly efficient low cost sensor controlled hand washing which is usable in different places within our geographical environment. The main aim of this work is a device that will automatically detects a human body nearby to the washing machine by the usage of proximity sensor and then allows the flow of water or soap
