The microwave oven is a common household appliance (家用电器) that has changed the way we cook and heat food. It was invented by Percy Spencer in 1945.
One day, while Spencer was working with a magnetron (磁控管), a device that produces microwaves, he noticed that a chocolate bar in his pocket had melted. This gave him the idea that microwaves could be used to cook food.
The first microwave oven was large and expensive. It was mainly used in restaurants and industrial kitchens. But over time, the size and price of microwave ovens decreased, making them more accessible to households.
