Washing machine.

Long before modern washing machines existed, people were already in the habit of washing their clothes. Many did it in rivers, with stones or special sands. Even soaps with animal fats were made to perform this task. The washing machine opened the doors to a world of greater hygiene and care for what you use every day.

Here is a brief history of how the washing machine became what we know today and some curious facts that we did not know about it:

XVI century

  •         From before 1600 the inventor Jacopo Strada and his son Ottavio, presented prototypes for washing machines. (XATAKA Smart Home, 2018)
  •         In 1766 the first German real machine model registered by Jacob C. Schäffer was launched. The inventor produced under his supervision the manufacture of 60 washing equipment. They consisted of a bathtub that saved bleach and fuel to heat the water, thanks to a rudimentary roller system. (XATAKA Smart Home, 2018)
  •         Back then the washing machines were used with fire.
  •         The American Nathaniel Briggs presented his “Clothes Washing” on March 28, 1797. This worked by means of steam. Ironed and drained by rollers driven by a crank.
  •         In 1850 appears the first commercial laundry and the first model of rotating drum patented by James King. This model facilitated draining.
  •         And on July 1, 1874, the inventor William Blackstone manufactures with his own hands and gives his wife what is considered by many as the first modern washing machine, by reducing its dimensions to make it an indisputable piece of the home. (XATAKA Smart Home, 2018)

20th century

  •         The women also played their role. Margaret Colvin with her Triumph Rotary Washer, a brand she patented in 1871 designed by her husband.
  •         Between 1862 and 1894 at least 48 American women patented washing machines or items related to squeegees and filters.
  •         Alva J. Fisher in 1901 patents one of the first electric washing machines. In the upper part of the machine he implanted a door with two hinges. This would prevent clothes from splashing when spinning. He added a gearbox so that the drum rotated by itself in different directions. He also presented diagrams with pressure valves.
  • 1908

  •         Then came a stunning success. In 1908 Thor was introduced to the market by the Harley Machine Company of Chicago. This was a machine with electric motor, washing drum and galvanized bathtub. The success of this new brand attracted the attention of more than 700 companies and in 1928 more than 913,000 washing machines were sold in the United States. (XATAKA Smart Home, 2018)
  •         As the years went by, the machines were superior. Already the machines washed, rinsed and extracted the water in a single operation (1937 by John W. Chamberlain). So until 1958 we already had the programmed cycles and drain programs.

Curious data to the present.

  •         In 1980 RAM arrives at washing machines.
  •         At this time SAMSUNG is a prestigious manufacturer.
  •         In 1994 we had a whole team with timers included.
  •         In the 2000s the fundamental objective of the manufacturers was the development of a water and electricity saving machine. So in 2006 we had a washing machine that only needed 250 ml of water per wash.
  •         In 2010 the touch screen is incorporated.
  •         Samsung launches the Vent Sensor to detect the obstruction in vents. The MultiStream, steam drying system to eliminate wrinkles, odors and rehydrate garments.
  •         In addition to all the aggregates that today have the most modern and efficient washing machines. In terms of speed of washing and drying among other aspects. There are mobile applications that are able to direct your washing machine or know the health of your appliance.

Definitely if we want to demonstrate the impact of technology today, the evolution of washing machines is a living example of this.

Fridge.

Undoubtedly one of the best inventions in history has been the refrigerator. We do not conceive our life without the preservation of our food. Thanks to him our water is cold, we keep the ice cream. In short we are going to know a little more about this indispensable appliance in our house.

  •         The first refrigerators were underground. Alexander the Great himself ordered the construction of underground chambers to conserve food supplies in times of war. (refrigeration, sf)
  •         The first popular brand of refrigerator was Kelvinator that in 1923 already had about 80% of the market. (the thousand answers, nd)
  •         It was not until the year 1800 that the first versions similar to modern refrigerators began to develop. Called ice house. These were designed by the American inventors Oliver Evans, Jacob Perkins and John Gorrie.
  •         Some mistakes were made during the evolution of this appliance. Among them the use of ammonia and sulfur dioxide that are toxic. This caused serious accidents to people due to the filtration of these gases into the environment.
  •         It can be said that the invention of the refrigerator arose from various chemical experiments. These showed that certain chemical reactions repelled the heat of a specific area. William Collen was the scientist behind these theories. (Who Invento, sf)
  •         Cooling systems need chemicals called refrigerants to be able to cool. (Who Invento, sf)
  •         In the 1927s in the United States, 60% of women did not have access to refrigerators because of their high commercial value. But between 1920 and 1930 prices fell dramatically and the use of these expanded in most households.
  •         Already in 1980 we had an appliance that besides good presence because it saved electricity. In this time it is added in addition to the energy saving, functionalities and the liquid dispenser.

Currently refrigerators, refrigerators or refrigerators continue to improve. Its style and modernity attribute to beauty in our kitchen. There is no doubt that we will always need them wherever we are. The refrigerator is one of our most indispensable appliances.

Air Conditioning

How would we survive in this age of heat if it were not for the air conditioners. Thanks to them many events from meetings to watching a movie in a movie theater can be done comfortably. Thank you very much to the great ingenious behind this great invention. Here we leave some interesting facts that maybe you did not know about this:

  •         The first air conditioners were conceived with the aim of dehumidifying, not cooling.
  •         Willis Carrier, American scientist, was in charge of eliminating the humidity that existed in the air of a printing press in Brooklyn. The paper wrinkled from the very existing humidity. This dilemma was very serious because it interrupted the work in the printing press. It was so that on July 17, 1902 Carrier completed the first draft of his air conditioning system. Said draft is the basis of the current ventilation systems. (Air Conditioning, sf)

These appliances are generally composed of: (Air Conditioning, sf)

  •         Compressor: Its objective is to compress a fluid that is in a gaseous state for its subsequent transformation.
  •         Condenser: Transforms the gas into liquid. This subtracts heat from the gas, and this absorbed heat is released as heat to the environment.
  •         Expansion valve: In this area the liquid is subjected to a loss of pressure, which lowers the temperatures.
  •         Evaporator: Here the vaporization of the liquid takes place absorbing the heat from the outside. This liquid is transformed into gas.

Curious facts:

  •         Most of the air conditioners in its structure have two fundamental parts. Internal (provides air circulation) and external (the compressor is usually here) unit.
  •         The air conditioners can be divided into two large families: Aires Solo Frio and Aires Heat Pumps.
  •         Air heat pumps cool the air in summer and heat it in winter.
  •         The first devices used toxic or flammable gas such as ammonia, methylene chloride and propane. (your air conditioning, sf)
  •         The principle of air conditioning had to be discovered for it to exist.

It was in 1842 that Lord Kelvin discovered this principle. With the aim of achieving a pleasant and healthy environment, the scientist created a hermetic refrigerant circuit based on the absorption of heat through a refrigerant gas. For this, it was based on 3 principles: (El aire acondicionado.com, sf)

  1.       The heat is transmitted from the highest to the lowest temperature, such as when we cool a coffee by inserting a metal spoon into the cup and it absorbs the heat.

two.       The change of state from liquid to gas absorbs heat. For example, if we wet our hands in alcohol, we feel cold the moment it evaporates, since it absorbs the heat of our hand.

  1.       The pressure and temperature are directly related. In a closed container, like a pot, we need to provide a smaller amount of heat to reach the same temperature as in an open one.

Thanks to the chemistry we had this amazing appliance. Currently the models are getting better and offer us multiple options. From different temperatures to heating if that is what we want. The best known and best of these brands are: Carrier, LG, Daikin, among many others. (Air Conditioning, sf)

Television

Last but not least, we bring the television. You have never asked how it is possible for it to work. Who came up with this brilliant idea that is our greatest entertainment. Well here we leave you a little history and curiosity about television:

  •         We owe this phenomenon to the existence of electromagnetic waves discovered by James C. Maxwell., Scottish scientist. Incredible, physics is behind our TV exists.
  •         Then with the experimentation with the cathode ray tubes of the physicist Karl F. Braun in 1897 a prototype was created. The fluorescent screen lit up when electrons hit it.
  •         It was not until 1924 that John Baird, officially known as the inventor of the television, managed to transmit an image through a screen at no more than three meters. Its principle was to send images through radio waves. This is the beginning of television.
  •         Initially they were made of wood, metal and glass. Currently this may require dozens of materials: noble gases (neon, etc.), fluorescent lights, light-emitting diodes (LED), among many others. Electroplated gold and silver electrodes can also be used in its cables. (Diario Información, nd)
  •         Spain met television for the first time at the International Exhibition of Samples in Barcelona in 1948 while in the United States it was in 1939.
  •         Already in 1950 began to emerge remote controls to control TV. Initially these had cable and were called “lazy bones” or lazy bones. (This in the United States)
  •         In 1954, the first color television model, RCA, was launched. The sales were not very big. It was twelve inches and its price was one thousand dollars.
  •         Thanks to the flexible OLED technology, there are now roller screens. You can take your TV as a scroll to wherever you go if you wish.

Industry Milestones:

  •         Sony launched the world’s first portable television in the year 1960, as did the first LED TV in 2004.
  •         The first to launch the plasma model to the market was the Philips company. Giant shells ceased to exist to have a TV of millimeters thick with increasingly larger screens.
  •         The thickness reduction of the screens has reached the 2.56 millimeters measured by the LG Signatura Oled television. (Expansion.com, sf)
  •         The quality of Oled technology is superior to Led. Currently classified as the highest quality televisions.

To Conclude:

After this journey through history and time we already know the magic hidden behind our appliances. It’s amazing how over the years the renovation and improvement of these continues to be enhanced. The human being sees no end.

Now surely every time you see your TV you will remember the great minds behind it. You will know that chemistry, physics and many other sciences are behind your most necessary equipment.
