From their initial design of a ‘washing and wringing’ machine in 1691, the washing machines have come a long way in their design and technology. The basic function and technology of a washing machine is to wash the clothes by rotating them and dry the water out by wringing. Today, many related technologies have made the washing machine an advanced and complete mechanical and compound household appliance.
Electromechanical timers came as a great technology to regulate the wash cycles. This was soon followed by varying motor speed settings. With this combination, the clothes got varying soak time, wash time, rinse time and dryer time. This regulated washing cycles and made washing more efficient. Water reuse was introduced in 1960s, by which hot water can be reused, enabling energy to be more efficiently.
With advancement in technology, the washing machines came with computer-controlled features. One of the main features is the automatic calculation of the wash cycle: detergent requirement, water requirement and time requirement based on the amount of load. There are even machines that can sense the fabric type and the level of water and adjust the wash cycle.
The following are some of the different related technologies in modern washing machines:
New technologies like waterless washing, prediction of energy consumption and connection to the home’s wireless network are in their research stage.
