Two hundred years ago before the 20th century, home washing and drying was done by hand. The only tools were the a tub and perhaps a scrub board. Only slowly were technological improvements introduced. A mundane but important example is the press which allows water to be squeezed out.
Since mechanization, washers have become steadily more complex since the very first fully automated one was introduced in the early 1900s. Electricity gave consumers the means of fine control over various automated functions like length of the spin cycle, the level of agitation, and temperature of the water.
The control panel of most modern washers and dryers exhibits a timer switch. For old-style appliances, this is a knob that is turned to point to different wash cycle settings. Newer appliances are electronically controlled with microchip and processor technology. The timer, in both cases, simply starts and shuts down various parts of the machine in the different phases of the wash cycle.
There are two other parts of the control panel which are important. The selector switch gives the user very fine control over the different parts of the wash cycle. The temperature of the water is tunable from cold to hot. The speed of the spin and agitation is modulated from gentle to regular. A start switch engages all functions including the timer.
Despite the advancement in technology, purchasing washers and dryers could be a little tough for people who are living in small residences, condominium or apartment units. First, they don’t have the luxury of space that would effortlessly support large home appliances.
The second challenge is that lots of apartments and condos are not set up with the correct connectors for washing appliances. For example some residences don’t have gas lines or exhaust vents for the dryer which makes it impossible for installing a conventional appliance.
