The modern electric hair dryer was the result of two inventions that had nothing to do with each other. They are the vacuum cleaner and the blender
Its point of origin is well known Racine, Wisconsin. And two of the first models called "Race" and "Cyclone," appeared in 1920, both manufactured by Wisconsin companies, the Racine Universal Motor Company and Hamilton Beach.
The idea of drying the hair using a draft of air originated thanks to the first announcements of the domestic vacuum cleaner.
In the first decade of this century, it was customary to assign several functions to a single appliance, especially appliances, since electricity was extolled as the supreme energy of history. This stratagem increased sales, and the public had become accustomed to multifunction devices.
The vacuum cleaner was no exception. One of the first announcements of the instrument called Pneumatic Cleaner featured a woman sitting at her dressing table, drying her hair with a hose plugged into the vacuum cleaner. With a criterion of asking why to waste hot air, the ad text assured readers that while the front of the machine sucked and removed dust and dirt, the rear generated a stream of fresh, pure air. Although the first vacuums were sold in moderately adequate quantities, no one knows to what extent their users made the best of them.
Be that as it may, the idea of drying hair through a stream of air was born. What delayed the appearance of a manual, electric hair dryer was the absence of a small and active motor despite its low power (what among investors was technically known as "horse fraction engine").
And here comes the blender
Racine, Wisconsin, is also home to the first mixer and blender to get milkshakes. Although the blender would not be patented until 1922, for over a decade efforts had been made to perfect a low-power engine, particularly the Racine Universal Motor Company and Hamilton Beach.
Therefore, in principle, the discharge of hot air from the vacuum cleaner came to marry the small motor of the blender to produce the modern hairdryer, made in Racine. Voluminous, energy deficient, quite heavy and with frequent overheating, the first manual dryer was, however, more efficient to shape hairstyles than the vacuum cleaner, and set the trend for the following decades.
The improvements introduced over the years. Thirty and forty included various controls for temperature and speeds. The first significant variation in portable dryers appeared in the Sears, Roebuck Fall-Winter catalog of 1951. This device, which sold for $12.95, consisted of a hand dryer and a pink plastic cap attached directly to the blow-molding nozzle and fitted to the woman's head.
Hair dryers became popular with the ladies from the first year of their appearance, but it was not until the late 1960s that men began to experience the difficulties of drying and combing their long hair.
