In the early part of the 19th century, stainless steel microwave ovens were developed. Stainless steel microwave ovenss shape was cylindrical and was made of heavy cast-iron. The gas oven saw its first use as early as the beginning of the 19th century as well. Gas stoves became very common household ovens once gas lines were available to most houses and neighborhoods. James Sharp patented one of the first gas stoves in 1826. Other various improvements to the gas stove included the AGA cooker invented in 1922 by Gustaf Dalén. The first electric ovens were invented in the very late 19th century, however, like many electrical inventions destined for commercial use, mass ownership of electrical ovens could not be a reality until better and more efficient use of electricity was available.
More recently, ovens have become slightly more high-tech in terms of cooking strategy. The stainless steel microwave ovens as a cooking tool was discovered by Percy Spencer in 1946, and with the help from engineers, the microwave oven was patented. The microwave oven uses microwave radiation to excite the molecules in food causing friction, thus producing heat.
Microwave (microwave oven / microwave), as the name suggests, is to use the microwave to cook food. Microwave oven is a cooking stove with a modern microwave heating of food. Microwave is an electromagnetic wave. Microwave oven from the power supply, the magnetron, the control part of the circuit and the cooking chamber and other components. Power supply to the magnetron about 4,000 volts pressure, the magnetron power excitation, continuously generating microwaves, through the waveguide system is coupled to the cooking cavity.
An oven that uses micro radiation waves as a source of heat in order to cook food as opposed to a fire source. Conceptualized in 1946, Dr. Perry Spencer allegedly discovered the heating properties of microwaves while studying the magnetron. By 1947, the first commercial microwave was in use in Boston, Mass.
