Title: Auto coffee drip machine
Inventor: KIM JA SUNG
IPC: A47J31/04
Filed: 2016-02-15
Abstract: Disclosed is an automatic drip coffee maker which can automatically extract coffee in a manual drip style. The automatic drip coffee maker may comprise a drip unit, a hot water supply unit, a support unit, a load cell, and a control unit. Specifically, the drip unit sprays a fixed amount of water to a dripper containing coffee powder, and the hot water supply unit heats water and supplies the same to the drip unit. In the support unit, a drip container for storing coffee extracted from the dripper is mounted, and the load cell is embedded in the support unit to measure weights of the dripper and the drip container so as to measure an actual amount of water sprayed to the dripper. The control unit controls water temperature of the hot water supply unit and determines an amount of water to be sprayed by the drip unit, wherein by using weight values of the dripper and the drip container received from the load cell, a difference between a predetermined amount of water to be sprayed by the drip unit and an actual amount of water that was sprayed to the dripper is calculated, and based on the calculated difference, the control unit can readjust the amount of water to be sprayed by the drip unit. Accordingly, the automatic drip coffee maker can reduce an error in the amount of water to be sprayed by the drip unit that occurs due to driving errors of the drip unit, and can spray a predetermined fixed amount of water to the dripper accurately, and thus can maintain uniform flavor and taste of coffee.
