One of the comforting things of many people around the world is drinking warm liquids such as tea, coffee, and herbal teas. Maybe you are one of those people who forget the exhaustion after hard work by drinking a cup of hot tea. The kettle is quite a popular item in most kitchens around the world. It is used mainly to heat water for tea or Turkish coffee and it comes in such a variety of shapes, sizes, and colors that motivated us to start blogging about it.
If you love tea you probably have one, but how was the kettle invented and how did it evolve into the fancy electric kettle models that we can buy nowadays?
Most people do not care about the key role of the kettle and its place in the kitchen. Perhaps this is due to oversimplification of the liquids heating process and the availability of modern types of appliances, whether electric kettles or coffee makers. It is enough to be willing to have the boiling water needed to make a cup of coffee or a cup of tea in less than a few minutes. However, not so long ago, applying such devices could never be assumed. Once upon a time a hot and soothing drink was prepared by fire and needed considerable effort, the invention of the kettle and the process of its development and evolution have helped man to meet his daily requests!
Studies show that ancient Chinese soldiers used boiling water to separate impurities and flavor them. They accidentally discovered that when green tea leaves are added to boiling water, they taste very good. In Europe, villagers boiled water and added wheat grains to give it a pleasant aroma and taste. This process is what is available today under the name of malt drink. Signs of a human desire to use boiling water have also been found in the United States. In the Wild West, many cowboys used early kettles to brew and brew coffee. The kettles at that time were mainly made of materials such as copper to transfer heat quickly.
If we look more closely at the use of kettles, we come from 2000 to 3500 BC, when the people of Mesopotamia used bronze kettles. Prior to the 19th century, most kettles were made of iron so that they could be placed directly on the flame. This trend continued until the invention of the electric kettle which resulted in a turning point in the development of kettles.
The first kettle to use electricity to heat and boil liquids was manufactured by Carpenter Electric in 1891. Boiling water in this device takes about 12 minutes. The heating elements of this kettle were also installed in a separate compartment under it. In the same year, an English inventor from R.E.B. Crompton designed an electric kettle based on the concept of heat radiators. Interestingly, this concept was used in the new version of the electric kettle "Carpenter Company", which was introduced in 1893 at the Chicago World's Fair.
Despite the design and development of the original electric kettles, the lack of integration in device components (especially the elements and chambers related to water heating), made their use difficult for most people, and therefore, in practice, these kettles were not well received. Nearly three decades later, in 1922, the Swan Company solved the problem by launching the first electric kettle with integrated heating elements. In this new and creative product, the heating element was placed in a metal tube in the water chamber of the kettle, and as a result, the water inside the kettle boiled faster than before.
Despite these two major developments in the design and production of electric kettles, it was Arthur Leslie Large's innovative idea that was able to increase the popularity of this product with his "Plug-In" kettles. His innovative electric kettle worked in such a way that electricity moved through a high-resistance element and transferred the generated heat to the water. At the moment when the temperature of the liquid reaches 100 degrees Celsius (its boiling point), the vapor of a strip consisting of two different types of metals heats up and due to its rapid expansion, one of them becomes curved. This will cut off the heating connection and prevent electricity from reaching it. Unlike the previous kettles where you constantly boil and whistle until someone, turn off. the new process of turning off the kettle ensures the safety of the device if the person is distracted, and at the same time, the boiling of the liquid inside the kettle is stopped,
In order to protect his valuable invention, Leslie Large filed a patent for an electric heating kettle with the British Intellectual Property Office, which in 1922 granted him a patent number "GB197982". . He further patented "GB269969" (a safety device for protection against overheating of electric heating elements) and "GB291216" (advancement in safety devices for use in electric heating elements) in 1926 and 1927. The record that well proves the commercial importance of this invention in the mind of its inventor.
It should be noted that although Mr. Large is not the first inventor of electric kettles, because of the popularity of his invention, it holds the title of inventor and original inventor of electric kettles. The popularity resulted in the growing use of them, just like many of the commercialization invented by Thomas Edison, whose name resonates as the inventor and key factor in their commercialization, despite the presence of other pioneering inventors.
Since then, there have been other technological developments in the production of kettles, including automatic electric kettles and the new generation of wireless kettles. In 1955, William Russell and Peter Hobbs developed a new type of fully automatic electric kettle. They founded a company called Russell Hobbs in the UK and successfully launched their innovative kettle.
This trend continued until the advent of modern technology and the possibility of intelligent and remote control, the new generation of kettles emerged. The I-pot is a Japanese invention developed by home appliance maker Zojirushi in collaboration with Fujitsu and telecom operator NTT. This interesting product, made at the request of the Japan Elderly Aid Association, is equipped with a kind of wireless communication system that records the movements of the device (number of uses) and records data for an unconnected person (family, nursing home support, and. ..).
If the use of the kettle is suddenly multiplied or stopped, the necessary warning is sent and intelligent monitoring of the disabled and the elderly is provided. Another example of a wireless and smart kettle is the iKettle, which allows users to remotely program via the iPhone. While you are driving home after a hard day, take the phone out of your pocket and send a message that the kettle is on, and after you get home, drink boiling water ready to drink a hot Nescafe. And you use it deliciously
