Since when is the tumble dryer exist?

For a long time, the sun took over the drying of clothes – even today clothes are hung on clothes lines in many countries or dried over shrubs and bushes. Although the first hand-operated tumble dryer was invented around 1800, it was only with the development of electric dryers in the 20th century that the device became interesting for households as well.
In 1940, the industrial designer Brooks Stevens designed a tumble dryer with window, in Europe came the first household appliance in 1958 on the market. Even in Germany, it should take decades for the tumble dryer in the household was common. Incidentally, the dryer in private households in Germany has still not prevailed, like the washing machine. In 2017, 42.2% of households in Germany were equipped with a dryer. To date, the principle of how the dryer works has hardly changed. Only design and additional functions have been revised and expanded again and again.
