Abstract: An automatic drip coffee machine includes a drip part, a hot water supply unit, a pedestal, a load cell, and a controlling part. The drip part pours water into a dripper containing ground coffee beans in a predetermined amount to brew coffee. The hot water supply unit heats water and provides the heated water to the drip part. The pedestal supports a drip container for supporting the dripper and storing the extracted coffee by the dripper. The load cell is disposed in the pedestal and measures weights of the dripper and the drip container so as to measure an amount of water actually poured from the drip part into the dripper. The controlling part adjusts a temperature of the water stored the hot water supply unit and sets a water injection amount of the drip part to be poured into the dripper.

Abstract: An automatic drip coffee machine includes a drip part, a hot water supply unit, a pedestal, a load cell, and a controlling part. The drip part pours water into a dripper containing coffee beans in a predetermined amount to brew coffee. The hot water supply unit provides the heated water to the drip part. The pedestal supports a drip container for supporting the dripper and storing the extracted coffee by the dripper. The load cell is disposed in the pedestal and measures weights of the dripper and the drip container. The controlling part calculates an error value between a predetermined water injection amount of the drip part and an amount of water actually poured from the drip part into the dripper using weights of the dripper and the drip container measured by the load cell and readjusts the water injection amount of the drip part based on the error value.
