The electric pressing iron is one of the predominantly used domestic appliances.
One of the problems with domestic electric pressing irons is that they can cause a fire if they are left plugged in for a prolonged amount of time. During this period, the pressing iron still consumes power which raises total energy consumption.
In finding a solution to this problem, Peter Azure and Kenneth Akanbodiipo – students from the Department of Physics at the Kwame Nkrumah University of Science and Technology (KNUST) – have designed a low-cost socket adapter that has the ability to turn off the pressing iron after a predetermined time, set by the user, elapses.
According to Peter and Kenneth, the adapter was designed to ensure energy is saved, and the fire caused by electric pressing irons are checked.
“This project was undertaken with the objective to save energy and to reduce the risk associated with leaving an electric pressing iron powered for an extended period of time,” they said.
The design uses a microcontroller, an AC-to-DC converter, and a rotary potentiometer that allows a user to set the desired ironing duration.
The adapter is programmed from five minutes to one hour, and provides power to the electric iron connected to it according to the selected duration.
After the selected time interval has elapsed, the socket automatically cuts power completely to the iron.
This reduces the risk of fire and injury associated with accidentally leaving the electric pressing iron unattended.
