Washing machine. (Laundry machine or washer)
A washing machine is an electronic appliance that may be of domestic or industrial use.
Washing machine are equipped with a central spinning drum. The drum has holes that introduce water as it turns; this makes easier the interaction between detergent and dirty laundry. An electric motor is responsible for the motion of the drum; most commonly, motors are located in the back of the drum or below, and motion is communicated by transmission bands. Direct Drive motors are directly attached with the drum forming a unit transmitting directly motion from the motor to the drum; as a result noise and vibration are reduced. Introduction of microelectronics has resulted in newer models leaving clothes clean and dry at the end of the cycle; with the help of sensors that control time, speed and temperature. Clothing re-placement algorithms even prevent excessive vibrations during the centrifuge cycle.
There are essentially two different models for washing machines; Front loading design washing machines and top loading designs. Front loading designs have the access door in the front and the drum spins at a horizontal axis; this way clothes are constantly falling as the spin cycle continuingly moves them upwards. Top loading designs have the access door top side. The spin of the drum may also be in a vertical axis, or there may be a hatch to access a horizontally spinning drum.
Washing machines have a sensor or automatic blocker on the access door; this device stops functioning when the door is open and may even prevent the door from opening if the washer is working. This device is comprised by a PTC resistance that, as it receives electricity, heats up and activates a bimetal; which in turn is connected to two terminals closing an electric circuit allowing electricity to reach other components of the washing machine.
A Metropolitan washing machine from the XIX century.
The first patent was granted in England back in 1691 in the “Washing and Wringing Machines” category. 1767 is the year Jacob Christian Schäffer publishes his design in Germany. In 1782; Henry Sidgier gets a British patent for a washer with a spinning drum; and in 1862 Richard Lansdale exhibits his patented compound rotary washing machine, in the London universal exposition.
In the United States, the first patent was for Nathaniel Briggs from New Hampshire in 1797; however there is no record of the design or the model type since a fire in the patent office in 1836 destroyed it. A “Clothes Washer with Wringer Rolls” was patented by John E. Turnbull in 1843.
A German made washer
Already in 1904 electric machine washers were been advertised; in the United States, sales had gotten to the 913.000 units in 1928. By 1940 60% of the 25 million homes that had access to electricity in the United States had a washing machine. Because of the great depression machines washers did not became a household item in the United States till early 1950; and the same did not occurred on developed Western Europe until after the Second World War. By the start of the 60’s washers were, an everyday item. Mayor European industrial corporations begin manufacturing important quantities of washers, and others even make washers the main source of prestige and income; and example of those are Kelvinator or Zanussi.
Esthetical and functional evolution of the washer machine has been significant, and even more so during the last few years, with all the applications of microelectronics. In the esthetical aspect, basic colors and square shaped electro domestic appliances were very trendy on the 80’s; nowadays more stylized and curved designs are available in a variety of colors.
In 2008, the University of Leeds designed a washer that only requires a cup of water (approximately 0.5L) in every cycle. Leaving clothes dry and clean using less than 2% of the water and energy of a conventional washing machine.
