19 19, a mechanic in Minnesota invented a toaster specially used in restaurants. Then, at 192 1, the mechanic obtained the patent of automatically ejecting the toaster. Before the outbreak of World War II, the toaster was what we see today. At that time, toast was regarded as the representative food of British and American culture, especially breakfast.
In the next 30 years, the popularity of toast is no longer limited to Britain and the United States, but begins to spread to all developed countries. These 30 years can be regarded as his golden age. From 65438 to the 1960s, it has developed into a prosperous French home art exhibition, and they even described the toaster as a star commodity at that time.
The invention of toaster didn't have as great influence as washing machine or TV set at that time, but it fundamentally changed people's diet in the morning. The function of toaster is heating. Before the invention of toaster, people could only eat cold bread, so after the invention of toaster, people can eat hot bread in the morning, which may be a warm-hearted invention for people at that time. Then toasters gradually entered thousands of households, and its price was not as expensive as washing machines or televisions. At that time, many people could use it, so it developed so fast that it entered every household and has been widely used until now.
