Upon reaching ((H) in the figure), the steaming / extraction setting screen 31 is displayed again, and the execution button icon 31c with a different color is displayed to identify the touchable state. When the execution button icon 31c is touched here, the extraction start screen 24 is displayed (FIG. 5 (E)), so when the start button icon 24a is touched, the extraction process is started from the steaming process and the status display screen 25 is displayed. Is displayed (FIG. 5 (F)).
なお、抽出開始画面２４には、簡易設定モード及び詳細設定モードで設定した湯温、湯量及び各種時間のデータを保存するための保存ボタンアイコン２４ｂ（図５（Ｅ））を備え、モード選択画面２１には（図５（Ｂ））、これらのデータを読み出して同じ抽出条件で抽出を再現するための読み出しボタンアイコン２１ｂを備える。 The extraction start screen 24 is provided with a save button icon 24b (FIG. 5 (E)) for saving data of the hot water temperature, hot water amount, and various times set in the simple setting mode and the detailed setting mode. 21 (FIG. 5 (B)) is provided with a read button icon 21b for reading out these data and reproducing the extraction under the same extraction condition.
