History
The idea of using microwave energy to cook food was accidentally discovered by Percy LeBaron Spencer of the Raytheon Company when he found that radar waves had melted a candy bar in his pocket. Experiments showed that microwave heating could raise the internal temperature of many foods far more rapidly than a conventional oven.
The first Raytheon commercial microwave oven was the 1161 Radarange, which was marketed in 1954. Rated at 1600 watts, it was so large and expensive that it was practical only for restaurant and institutional use.
Due to the rapid development of society, people lives are becoming increasingly hectic and personal schedules become more full. In order to adapt to the modern life, people are looking for simple and fast way to cook an enjoyable meal. That is one of the reason why the microwave oven became an important home kitchen appliance.
First of all, microwave oven help me to save a lot of time, especially when I want to refrozen something or reheat food. Also because it is very simple and convenient to use, all I need to do is put the food into it , set up the time and press start, then do not need to take care anymore.
