Washing machine It is a term that can be used in feminine (the washing machine ) or in masculine (the washing machine ). This is called the machine which is used for laundry .
Mentioned in the singular as washing machine or laundry , the concept is often used in the Argentine territory and in Uruguay , although in others countries the notion of washing machine . Washing machines and washing machines, therefore, are synonymous: they allude to the same.
A washing machine, in short, is an electromechanical device that has a drum where the Dirty clothes . Said drum, in turn, has holes that allow water to enter.
In this way, the washing machine must be connected to the electricity grid and also to the water supply network. The user has to add soap or Detergent in the indicated place, turn on the machine and open the tap (the tap). Thus, thanks to an electric motor, the drum of the washing machine rotates while it is filling with water, which is mixed with the soap. In general, the standard process includes several washes and rinses and a spin so that the garments are as dry as possible.
The most modern washing machines have sensors that allow to control the speed of rotation of the drum and the temperature of the water, among other variables. They also indicate the weather It delays washing.
In general, there are two main types of washing machines: opening or load higher and of opening or front loading . In the case of the top opening washing machines, the door that provides access to the drum is located at the top, while in the front opening washing machines, it is located in the front sector.
The history of the washing machine dates back to the end of the 17th century, more precisely to the year 1690, when the first patent was registered in England, which was included in the category of washing and draining machines. Needless to say, this first prototype It did not operate with electricity, but in an absolutely manual and mechanical way.
Almost a century later, in 1767, the German inventor Jacob Christian Schäffer He published his own design, and so more and more appeared, each with certain characteristics that offered greater comfort or better performance. In 1782, for example, English Henry Sidgier got a patent for a model with a rotating drum, and in 1862 the first compact rotating washing machine appeared in the London Universal Exhibition .
An unfortunate anecdote related to the history of the washing machine took place in the United States between the end of the 18th century and the beginning of the 19th century, when a fire broke out in the Office patent destroyed every trace of the patent that the inventor Nathaniel Briggs He had obtained it in 1797. If it had been recorded, today it could be officially declared as the first American to have patented a washing machine.
One of the most interesting inventions for users back then was the "rollers drained ", which allowed the clothes to pass between them as if it were dough for fresh pasta in order to remove all the water that had been absorbed and leave it ready to tend outdoors. This was much better than squeezing it by hand since it avoided wrinkles and, needless to say, decreased physical effort.
At the beginning of the 20th century the first electric washing machines appeared in North America and by 1930 they had reached an important level of popularity. In 1940 alone, it is estimated that there were one in six out of ten houses with access to electricity. It wasn't long until it became a Article of massive use worldwide, and thus emerged the great brands that today dominate the washing machine market.
