As early as 1947, the first micro-slope stove came out, which set off a revolution in cooking stoves. Its inventor is Percy Spencer of the United States. It has a 1700W water-cooled magnetron, weighing more than 340 kilograms and reaching 6 feet in height, which greatly increases the difficulty of moving, and the finished product can only be placed in hotels when it is inspected. At that time, it was also very expensive. Its invention was first inspired by the radar device, so it was called "radar wave" furnace at the earliest time.
1964, Keiji Kokura of Japan changed into the magnetron of the microwave oven, which also greatly reduced the price of the microwave oven. However, in 1965, George? Foster improved the microwave oven, and finally in 1965 George? Foster and Spencer designed a practical and cheap microwave oven together, and held a press conference on microwave ovens in the United States, which was a great success. After this improvement, microwave ovens have gradually entered thousands of households. Finally, in 1967, the microwave oven was improved again, especially in size, from the original size to the present size, and it moved quickly, which greatly shortened the cooking time and successfully changed people's initial impression of the microwave oven.
Before 1980s, the development of microwave ovens in China was in the exploratory stage. China has been exploring the microwave oven ever since. Finally, in 1982, the first microwave oven in China was born in Nanjing. This is the development history of micro-slope furnace. Compared with ordinary cookers, microwave ovens save more electricity, heat more evenly, and food will not be endogenous. I hope the above contents can help you better understand the microwave oven.
