Drip coffee makers originated many years ago. Approximately 125 years ago. The inventor of the method of drip coffee brewing created a combination of two containers, one above the bottom section. In the upper section coffee grounds were placed. The upper container had small holes in the bottom, where the poured water would drain. This water having run through the brewed coffee. resulted in the drip brewed coffee.
Brewing a pot of coffee through many years was considered quite simple. This was accomplished by taking ground roasted coffee beans, adding them to a pan of hot water. Boiling the water and sometimes going by the smell to guess when it had cooked long enough. Then a cup of coffee could be enjoyed. Campground style pot of coffee is similar to this method.
Several inventors tried there hand at creating automatic coffee brewing appliances. This was in the latter part of the 20th century. The very first automatic drip brew coffeemaker for home use became popular in 1972. Since that time many changes have been made, in the design and the materials used. Glass instead of metal came into use for the carafe or bottom pot holding the brewed coffee. The need for more decorative type appliances in the home became in demand by the homemaker. The manufactures aimed to please the public. In doing so decorative home colors in materials made from plastic were used. The area where water was poured into and the brewing basket became a part of the home decor.
The electric drip coffeemaker contains a few simple mechanisms. The operation performance is guided by a flexible hose at the base of the reservior that the water is poured into. This hose goes to a metal tube, which has the job of heating the water. The tube is usually made of aluminum. The element for heating the water surrounds the metal tube. The method of moving the heated water is called “thermosiphon principal” This creates a heated pressure along with a siphoning effect. A thermostat controls the temperature of the water. The water then passes through a special insulated hose.
A spray of water goes onto the basket of ground coffee. A filter placed below the coffee grounds in the basket prevents them from entering the brewed coffee liquid. A heating element is located under the carafe. The finished product was created by a drip coffee maker.
