Electric ovens were available as early as the 1890s. However, at that time, the technology and distribution of the electricity needed to power these early electric appliances still needed improvements.
The Carpenter Electric Heating Manufacturing Company invented an electric oven in 1891. An electric stove was exhibited at the Chicago World's Fair in 1893. On June 30, 1896, William Hadaway was issued the first patent for an electric oven.
The electric oven is a heating chamber which is meant for baking foods by means of conversion of electrical energy to heat or thermal energy. Due to vast improvement in technology, the new and interesting idea of an electric baking oven was brought about by an American Engineer called Dr. Percy Spencer. By late 1946, the Ray Theon Company had filed a patent suggesting that baking ovens can be used to cook food, baked bread and pre heat food.
The first electric stoves use heating elements made of high-resistance metal to produce heat. The cooktop (range) surface had one or more circular heating elements, insulated with compressed magnesia and sheathed in a spiral metal tube. Heating elements for the oven are of similar construction but an elongated loop to distribute heat. Elements were made as plug-in consumer-replaceable parts and could also be easily removed for cleaning.
