First, as shown in FIG. 5, the open / close operation lever 67 is raised to a standing posture, and the lid lock mechanism L is switched from the released state (the state shown in FIG. 5 (a) to (b)). The lid body 5 is swung to the fully open position side, and the upper side opening 4 is opened.

  Next, as shown in FIG. 9, the pod holder H in a state where the holder main body 40 and the pod receiving member 48 are assembled is positioned by the knob 44 and the positioning blade 45 via the upper opening 4. In the state where the concave portions 58A and 58B are inserted and the outer cylindrical portion 41 is inserted through the through hole 54, the flange portion 43 is placed on the positioning step portions 59s of the plurality of ribs 59, and the holder body H The pod pod M is mounted on the pod receiving member 48 of the pod holder H, with the lower surface mounted on the upper surfaces of the plurality of ribs 59. The cafe pod M may be placed on the pod receiving member 48 before the pod holder H is mounted in the extraction chamber 3 or after a spout member 30 described later is mounted on the insertion / removal port 52.

Then, as shown in FIG. 10, the spout member 30 is opened with the rail 35 a of the spout member 30 along the guide rail 52 a of the insertion / removal port 52 (see FIG. 7). It is attached to the insertion / extraction port 52 in a form of sliding along S.
At this time, as shown in FIGS. 10A and 10B, the arc-shaped notch 33A formed in the outer wall portion 35 of the spout member 30 as the spout member 30 is attached becomes the extraction chamber. The outer cylindrical portion 41 is slightly lifted upward while being guided along the arc-shaped cutout portion 33A by slightly contacting the tapered surface 41a of the outer cylindrical portion 41 inserted through the three through holes 54.
When the spout member 30 is further slid, the outer cylindrical portion 41 lifted upward is guided downward along the tapered surface 34b of the cracked cylindrical portion 34 as shown in FIG. 10 (c). The taper surface 41a and the taper surface 34b are close to each other with a predetermined gap as described above. Thereby, the front-end | tip of the outer side cylindrical part 41 can be easily penetrated into the position of the upper side of the cracked cylindrical part 34 (refer FIG. 11).

When the description is added, as shown in FIG. 12, in the locked state in which the lid 5 is held in the closed state, the spout member 30 is slid along the sliding direction parallel to the opening surface S of the upper side opening 4. Even if it is attempted to be removed from the insertion / removal port 52 of the extraction unit 2, the tapered surface 34 b of the cracked cylindrical part 34 contacts the tapered surface 41 a of the outer cylindrical part 41 of the pod holder H pressed downward by the lid 5. The spout member 30 cannot be slid in contact, and the spout member 30 is prevented from detaching from the extraction unit 2. That is, when the spout member 30 is about to slide, the outer tubular portion 41 is moved upward via the tapered surface 41a of the outer tubular portion 41 that contacts the tapered surface 34b of the cracked tubular portion 34 of the spout member 30. Even if it is going to be lifted, the hook-like portion 43 of the holder main body 40 in which the outer cylindrical portion 41 is formed cannot abut against the outer peripheral wall portion 81 of the inner lid 80, and as a result, the spout member 30 The sliding movement is prevented. Therefore, it can prevent more reliably that the spout member 30 detach | leaves during extraction operation | movement, and can improve safety | security.

  On the other hand, in the extraction operation, when coffee extracted from the cafe pod M and ejected from the extraction hole 47h of the pod holder H collides with the bottom surface (inclined surface) in the cracked cylindrical portion 34, the coffee is broken. While foaming in the inner space, it can be guided to the slit 34a formed on the spout 33 side in the circumferential direction of the cracked cylindrical portion 34. Therefore, the coffee containing the well-foamed foam (so-called crema) is allowed to flow from the space in the cracked cylindrical portion 34 in the spout member 30 to the space on the spout 33 side through the slit 34a. It can be discharged from the mouth 33 into the coffee cup.

When the pod holder H and the spout member 30 that have been soiled with coffee or the like are washed or cleaned in this manner after the extraction operation or the like is performed, in the state shown in FIG. L is switched from the locked state to the released state, and the lid 5 is swung to the fully open position to be in the open state.
In this open state, the pod holder H can be detached from the extraction chamber 3 through the upper opening 4 without being obstructed by the presence of the lid body 5, and the spout member 30 is also in the presence of the pod holder H. Since it can be separated from the extraction unit 2 without going through the extraction chamber 3 (upper side opening 4) without being disturbed and blocked (allowed) by the spout portion separation prevention mechanism P, it can be removed from the extraction chamber 3. The removal of the pod holder H and the removal of the spout member 30 from the extraction unit 2 can be performed separately. For example, when the pod holder H is attached to the extraction chamber 3 and only the spout member 30 is detached and cleaning or cleaning is performed, in the opened state in which the lid 5 is opened, FIG. As shown in the order of b) and (a), the outer cylindrical portion in which the taper surface 34b of the cracked cylindrical portion 34 is released from being pressed by the lid 5 by sliding the spout member 30 in the detaching direction. The outer cylindrical portion 41 is easily lifted upward while the tapered surface 41a of the outer cylindrical portion 41 abuts against the tapered surface 41a of the 41 and is slidably guided along the tapered surface 34b of the cracked cylindrical portion 34. The outer cylindrical portion 41 is released from entering the cracked cylindrical portion 34, and the arc-shaped notch 33A of the spout member 30 slightly contacts the tapered surface 41a of the outer cylindrical portion 41, The outer cylindrical portion 41 is turned into the arc-shaped cutout portion 33A. While being guided me that lifted upward, the spout leaving the member 30 from the extractor 2 can be easily performed. Thereby, the detachment of the pod holder H from the extraction chamber 3 and the detachment of the spout member 30 from the extraction unit 2 can be performed reliably and easily, respectively. Note that the pod holder H can be detached from the extraction chamber 3 through the upper opening 4 while the spout member 30 is attached to the insertion / removal port 52, and the pod holder H and the spout member 30 can be simultaneously removed. It can also be removed.
Therefore, the pod holder H and the spout member 30 cannot be detached in the closed state in which the lid body 5 is closed, and the safety of the pod holder H and the spout member 30 is ensured in the open state in which the lid body 5 is opened while ensuring the safety. It is possible to provide a beverage extractor capable of arbitrarily removing both or one of 30 and further improving convenience.
