Today microwave use in many families, and to the surprise this device someone is difficult. It is available at a price, and not a luxury, has a small size, convenient and easy to use. But it was not always so. We offer a brief history in the time of the creation of the microwave. It is interesting because that was a microwave oven in its original form.

Agreement on this issue there is to this day. Russia and the United States challenged the authorship of the microwave oven, however, the patent belongs to the inventor from the United States.
historians version of who invented the microwave oven
One of the most plausible versions of the sounds - American engineer and inventor Percy Spencer
once, in the course of experimental work with the magnetron, I discovered that chocolate, which was in his pocket, in the course of work melted. There is also a version that he put the sandwich on a magnetron, and then discovered the heating of food in the course of operation. It is likely that in the course of experiments, he got burned, but when he received a patent for the invention of the microwave oven, it has decided to keep silent in order not to spoil the image of his own creation.
Another version set out in the newspaper "Trud" of 17.05.2011, states that more June 13, 1941 in the pages of the same newspaper described a device that uses microwave currents in order to process the meat. Development supposedly conducted in the laboratory of electromagnetic waves, Scientific Research Institute of Meat Industry.
There are also versions of the German development time of the Third Reich, Fell into the hands of scientists from the USA and the USSR. But they have not received confirmation.
Invention patent mikrovolnovki
The issuance of a patent for a prototype microwave oven held at 1946 year. It was called «Radarange», first release it is dated 1947, was used to produce quickly defrost foods. It was used only by military personnel in canteens and hospitals.
Interesting to know!
The first microwave height of about 180 cm and weighed about 340 kg. Power consumption twice as modern analogues and consumes 3 kW, the cost of it was pretty big - 3 thousand. dollars.
The first microwave ovens
Serial production of the above model began in 1949. The first household microwave oven for the general population has been created by the company «Tappan Company» in 1955. Serial production of household microwave ovens dates back to 1962 year, the company has established its «Sharp», Japan. The announcement was met with disbelief and special popularity not won.
In the Soviet Union the beginning of mass production of microwave ovens dates back to the early '80s. the last century. Releasing them engaged ZIL, YUZHMASH plant "Elektropribor" (Tambov), Dnipro Machine-Building Plant named after VI AND. Lenin.
Who invented the microwave oven: the Soviet Union or the United States?
As already described above, to ascertain the authorship of the invention is not possible. The fact is that in 1941 the Soviet Union was embroiled in heavy and bloody in the history of war, and all was simply not up to the present invention. According to the existing international rules, the authorship is recognized for those who took out a patent. Consequently, an official author of the microwave oven is Percy Spencer from USA.
Microwave: since the invention to the present day
Since the establishment of the first models to this day the appearance of the microwave oven has changed a lot - it has become more compact, easier to use, there was a mass of useful features:
- Business card of any microwave - turntable, appeared in 1962 thanks to the development of Japanese company Sharp.
- A microprocessor controls the operation of the microwave, first began to be applied from 1979.
- In the late '90s. of the last century there were a model where the device managed by the built-in microcomputer, then there were the grill and convection function.
Panasonic has introduced another innovation - Inverter microwaves. Unlike conventional models where the magnetron power comes from the transformer in the inverter furnaces power is supplied through an inverter, which converts direct current into alternating. As a result, on the heated food is regulated, softer impact, allowing it to warm up evenly. In addition, the inverter size smaller than the transformer, which also reduces the weight and dimensions of the device, and without become compact in comparison with the first prototypes vesivshimi more than three hundred kilograms and the size is not inferior to large refrigerator.
On a note! The first models of microwave ovens weighed about 300 kg.
Modern furnaces, unlike primary, equipped with a timer that allows the right time to automatically turn off the device. Thus, the microwave is not necessary to follow as before, she will turn off after a certain time and beeps.
In short, progress is not in place, and many companies are competing with each other for the market, offering the customer more and more new models with different features. Despite the emergence of a variety of different innovations, actions microwave principle since its invention did not change. It still uses the current ultra-high frequency heating and cooking.
