Problem to be solved: to provide a water extraction type coffee extraction apparatus capable of extracting coffee excellent in flavor in a short time.A coffee extraction apparatus 1 is a filter 4 for receiving coffee powder g disposed on an opening 3a of the container 3, a water reservoir 5 for storing water, and a dropping member 6 for filtering water supplied from the reservoir 5 and dropping it onto the coffee powder g in the apparatus A frame 2 for supporting the water reservoir 5 and the dropping member 6 above the filter 4 is provided. The dropping member 6 includes a pendulum mechanism 13, 14, which has a riser curve movement, and has a dropping port 16A at its lower end. When an initial initial vibration is applied to the dropping member 6, the end of the filter is moved so as to fill the constant range above the filter 4 by drawing a Lisa Jue curve and dropping the water to the coffee powder G.Diagram【課題】短時間で風味に優れたコーヒーを抽出できる水出し式のコーヒー抽出装置を提供する。【解決手段】コーヒー抽出装置1は、容器3の開口3aの上に配置されコーヒー粉Gを受ける濾し器4と、水を収容する貯水器5と、この貯水器5から供給される水を濾し器4内のコーヒー粉G上に滴下させる滴下部材6と、貯水器5と滴下部材6とを濾し器4の上方に支持するフレーム2とを具備する。滴下部材6は、リサジュー曲線運動をする振り子機構13,14を含み、それの下端に、滴下口16aを有する。滴下部材6に任意の初期振動を与えると、その先端はリサジュー曲線を描いて濾し器4の上方の一定範囲を稠密に埋めるように移動しつつ、滴下口16aからコーヒー粉Gへ水を滴下させる。【選択図】図1
