At the same time, the rotary shaft 32 and the spray head 30 rotate around the axis, the hot water supply pump is driven for a predetermined time, and the hot water pumped from the hot water storage tank 15 is rotated from each of the ejection ports 31 of the spray head 30 to form a shower shape. And is sprayed toward the coffee powder Cp in the dripper 45.

As a result, the coffee is extracted, and the extracted coffee flows from the outlet 46 of the dripper 45 into the concave hole 53 and the slit 54 of the pedestal 50, is divided into both extraction ports 55, and then, as shown in FIG. It is poured into each cup C as shown by the arrow. During this time, since the stand 50 and also the dripper 45 are kept warm, heat is suppressed as much as possible before the coffee passes from the dripper 45 through the stand 50 to the extraction port 55, and the coffee is warm. Pour into cup C at an appropriate temperature. When extracting coffee for one cup C, as shown by the chain line in FIG.
A cup C is placed on the upper side of the extraction ports 55, and a switch for extracting one cup is operated by the operation panel 82. Similarly, the extracted coffee passes through the inside of the dripper 45 and the stand 50, which are kept warm, and is poured into the cup C from both extraction ports 55 in a warm state.

As described above, according to this embodiment,
The coffee extracted by the dripper 45 is received by the stand 50 on which it is placed, and then poured into the cup C from the extraction port 55 provided on the stand 50. Since the heat is maintained by the heat of the heater 78 mounted on the attachment body 70, it is possible to pour the coffee into the cup C at an appropriate temperature without lowering the temperature of the coffee. Further, since the stand 50 has a flow dividing function, it is possible to directly pour the coffee into the two cups C while keeping them warm. Of course, you can save the trouble of transferring from the decanter. Since coffee passes through the stand 50, it needs to be washed frequently for hygiene, but the stand 50 is removable and can be easily removed by pulling it as shown by the arrow X in FIG. Can be washed.
