A drip coffee maker works by sending hot water over coffee grounds that are held in a filter. The coffee brews and then drips into a heated container that keeps the coffee hot and ready for consumption.Continue Reading
Drip coffee makers are constructed with a reservoir into which cold water is poured. From the reservoir, the cold water travels via a one-way valve through a heating tube and is distributed over the coffee grounds. Some drip coffee makers are designed with a plastic disc that enables hot water to drop onto the coffee grounds.
The drip coffee maker is a simple electrical device that generally operates with a power cord and a heating element. The apparatus consists of a resistive heating device that transfers heat to an aluminum tube through which water can easily flow.
The resistive heating element is made up of a coiled wire that heats the cold water that is poured into the unit. Drip coffee makers are also equipped with sensors and fuses that prevent the coil from becoming too hot. In the event of overheating, the current is cut off, and, once the apparatus has cooled, the current is turned on again. This cycle keeps the coil at a functional temperature and prevents the coffee maker from creating a safety concern.Learn more about Coffee & Tea
