Washing machines

Operating conditions and requirements

Technological advances and recent environmental demands have led manufacturers to focus their efforts on improving washing and rinsing efficiency whilst lowering power and water consumption. Home appliance regulations are a concern for every country. European Community and US Federal Agencies (FTC) have established energy consumption regulations with labeling initiatives. Labels are placed on each appliance to aid consumers in their purchasing decisions. These regulations take into account energy efficiency, noise level and service life.

In addition to the normal features we look for in a washer, such as long operational life and rust free components (stainless steel, plastic and other materials for the drum and tub), there are now new developments:

  • Increasing speeds in the spin cycle (1600 rpm and over) to improve water removal from clothes
  • Electronic power managing systems that regulate water consumption according to laundry load
  • Systems that can electronically control drum speed, position and rotation sense
  • Reduction in machine size and silent running that gives flexibility in room installation placement

Different design solutions are proposed by washing machines manufacturers:

  • Horizontal axis - front loading washing machines 
  • Horizontal axis - top loading washing machines
  • Vertical axis - top loading washing machines
