If you are a coffee lover and ever wondered how do home coffee makers work, you've come to the right place. We will do our best to explain in the simplest of ways. The most common and cheapest house old coffee makers are usually drip coffee makers.
Drip coffee makes brew coffee as their name suggests, they drip boiling hot water over grounded coffee beens. The drip coffee maker has four main parts i.e. the reservoir, the heating element, the filter with the filter basket and the carafe also know as the brew pot.
Water is filled in the reservoir and grounded coffee beens are placed in the filter basket with a coffee filter paper. The heating element is built under the brew pot so as to keep it warm. The tube from the reservoir passes through the heating element , which heats up the water causing it to partially form steam. The tube then feeds into the filter basket, the steam formed becomes bubbles of stream and rise up along the narrow tube pushing drops of water with it into the filter basket.
The drops of water are heated up due to the heating element and the steam that pushed it up, these hot drops of water fall on the grounded coffee beens in the filter basket. As the hot water runs through the coffee beens it picks up the coffee oils and then goes through the filter paper and drips into the carafe or brew pot. And that's it! This is how simple a coffee maker is.
