A drip coffee maker consists of three main components:
- The Reservoir: this holds the water that is poured into the coffee pot. At the bottom of the reservoir there is a hole.
- The Tube: you will also find that there will be a tube (usually white or clear) that leads up from the bottom of the base of the reservoir. This tube carries the hot water to the drip area.
- The Shower Head: In the majority of drip coffee makers, above the basket that you will put your grounds in you will notice (usually on the lid) that there is a piece that resembles the shower head in your shower. The tube that was mentioned previously carries the hot water up to the shower head so that the water can be sprayed over (or dripped down on) the coffee grounds.
Water moves through your coffee pot through the help of gravity, and the bubbles from boiling water. This is why coffee makers tend to be very reliable machines, there aren't any pumps that can wear down or tear up. A great simplistic design is what brings you your coffee from a drip coffee maker each morning.
