The operation will be described below. In the standby state, the shoe 14 is held such that the outlet 14a of the coffee powder 9 is further away from the extraction chamber 19. In response to the sale signal, the swivel drive 23 rotates the swivel 14 about the shaft 24 so that the outlet 14a is positioned above the extraction chamber 19. When the coffee powder 9 has been charged into the extraction chamber 19, the shoot 14 returns to the standby position. Hot water 12 is in extraction room 1
9, the valve body 6 seals the upper opening 5, and the mixed liquid 1
8 is pressurized by a pump 17 and extracted.

(Embodiment 3) FIG. 3 is a detailed view of a shot rotating drive device. In FIG. 3, reference numeral 25 denotes a stopper which comes into contact with the stand-by shot 14, and reference numeral 26 denotes coffee powder. 9 is a cam having a protruding portion 26a which comes into contact with the SHUT 14 at the time of insertion, and a motor 27 is provided on the motor shaft 27a.
And rotated. Reference numeral 28 denotes an elastic body which urges the lower end of the shoe 14 toward the stopper 25. The same components as those in the second embodiment are denoted by the same reference numerals, and detailed description is omitted.

The operation will be described below. In the standby state, the shoe 14 is in contact with the stopper 25. The motor shaft 27a is rotated by the sale signal, and the projection 26a of the cam 26 comes into contact with the shoot 14, and the shoot 14 is rotated until the outlet 14a comes to the extraction chamber 19. When the coffee powder 9 has been charged into the extraction chamber 19, the motor shaft 27 is turned off.
is rotated, the protruding portion 26a of the cam 26 is separated from the shoe 14, and the shoe 14 is pulled by the elastic body 28 so as to stop.
25 that collided with the shot
The flour is forcibly dropped out of the shoe 14.

[0024]

As described above, according to the present invention, coffee powder can be directly introduced into the extraction chamber from the stall.
In addition, since the hot water discharge port is provided separately from the shoot, it is possible to prevent water drops from adhering to the inside of the shoot. Further, there is an advantageous effect that the coffee powder remaining in the shoe can be forcibly dropped outside the shoe.
