Reference numeral 80 denotes a mounting portion having a plurality of holes formed in the base 61, and the mounting portion 80 mounts a demitasse coffee cup 81 into which this type of coffee is placed.

The pump 70, the water channel 46, the outlet 47,
A flow path 82 is formed with the nozzle hole 53.

The operation of the pressurized pouring type brewing device for coffee or the like will be described below.

First, the coffee brewing preparation and brewing operation will be described.

First, the heating element 45 is energized to raise the temperature of the heating block 41, and after reaching the required temperature, the temperature is controlled to the required temperature by an automatic temperature controller (not shown).

Then, a required amount of water is put in a water container (not shown), and the handle 49 is rotated to the position shown in FIG. 1 to release the engagement between the holder 48 and the hook plate 68.

Next, the handle 49 is lifted and the movable part 72 is hinged 73.
Rotate upward around. Capsule 5 in this state
0 is placed on the setting section 65, the handle 49 is lowered, and the movable section 72 is lowered. The guide ring 51 closely accommodates the capsule body 55 having a substantially conical shape, the nozzle 54 breaks the upper portion of the capsule 50, opens the nozzle hole 53 in the coffee powder 58 in the capsule 50, and the end face of the guide ring 51 and the biting rib. Hold the rim 59 at the upper end of 63. further,
When the handle 40 is rotated, the hook plate 68 loosely fitted to the holder 48 engages with the holder 48, and the guide ring 51 further descends to move the bite rib 63 and the guide ring 51.
And bite the rim 59 in an airtight manner.

Next, the demitasse coffee cup 81 is placed on the placing portion 80 and the pump 70 is operated. As a result, the water in the water container (not shown) is pumped by the pump 70, heated by the conduction heat from the heating block 41 while flowing through the spiral water passage 46, becomes hot water, and flows through the outlet 47 to the nozzle 54.
The coffee powder 58 in the capsule 50 is emitted from the nozzle hole 53 of the. Then, the hot water passes through the coffee grounds 58 and brews the coffee, then breaks the thin portion (not shown) of the bottom portion 56 by water pressure through the filter 57, drops the setting portion 65 from the discharge port 64, and demits the coffee cup. Retain in 81. When the required amount of coffee has accumulated in the demitasse coffee cup 81, the pump 70 is stopped.

Next, the operation and cleaning after brewing coffee will be described.

First, the handle 49 is rotated in the opposite direction to that before the coffee is brewed to release the engagement with the hook plate 58,
Raise. Lower end of guide ring 51 and bite rib 63
The rim 59 of the capsule 50 that has been bitten by is released, but the capsule 50 that is tightly press-fitted into the inner surface of the guide ring 51 by water pressure rises together with the guide ring 51. As a result of this rise, the rim 59 contacts the hook plate 68 that is fixed at a distance smaller than the diameter of the rim 59. When the handle 49 is further raised, the capsule 50 is separated from the guide ring 51. The capsule 50 separated from the guide ring 51 falls on the setting portion 65.

On the other hand, as the handle 49 rises, the movable portion 72 also rises, and the protrusion 78 pivotally supported by the movable portion 72 causes the contact portion 7
While the 9 is brought into contact with the movable portion 72, the locking rod 75 is rotated counterclockwise, and the exclusion fitting 74 pivotally supported by the locking rod 75 is pulled. As a result, the guide ring 5 described above
The capsule 50 dropped from 1 to the setting portion 65 is pressed by the exclusion fitting 74 to move from the setting portion 65 to the inclined portion 66, slides along the inclined portion 66, and is provided below the inclined portion 66. It falls on the saucer 69.

Further, when the handle 49 rises, the protrusion 78 that locks the locking rod 75 and is rotated and raised together with the movable portion 72 gets over the locking rod 75 from the capsule base 60 side to the pump 70 side. Then, the locking rod 75 is rotated clockwise by the biasing spring 77 and returns to the position when the capsule 50 is set. The protrusion 78 that has passed over the locking rod 75 is the handle 4
When 9 is lowered, the protrusion 78 is also lowered together with the movable portion 72, and is rotated clockwise while contacting the locking rod 75, and the locking rod 75 is crossed over from the pump 70 side to the capsule base 60 side.

As described above, according to this embodiment, the capsule 50 in which the coffee powder 58 is sealed is used, and the guide ring 51 is used.
Exclude the exuded capsule 50 in conjunction with the lifting and lowering of the metal fitting 7
Since 4 is automatically removed and stored in the tray 69, preparation for coffee brewing and cleaning after brewing can be performed very easily.

In the above embodiment, the coffee powder 58 as the exudate is sealed in the capsule 50 as the exudate container, but the exudate container does not necessarily have to be sealed, and the point is that the exudate is not exuded. It is good if things can be stored.

Further, in the above-described embodiment, the projection 78 is configured to interlock the guide ring 51 that moves up and down by rotating the locking rod 75 and the removing metal fitting 74, but the container removing means is provided in the moving storage unit by a link and a cam. You may interlock. Further, it goes without saying that the exudate is not limited to the coffee powder 58.

EFFECTS OF THE INVENTION As described above, according to the present invention, the capsule can be removed from the set portion only by pivoting the movable portion with respect to the base, and the movable portion is returned to the original state to form a new capsule. All preparations for leaching are completed. The invention thus makes pre-leaching preparation and post-leaching operation and cleaning very simple. Further, the configuration of the present invention is
It is simple and reliable in operation.
