Although 78 is rotatable in the clockwise direction, it does not rotate in the counterclockwise direction because the contact portion 79 contacts the movable portion 72. 80 is the base
61 is a placing part having a plurality of holes, and this placing part 80 places a demitasse coffee cup 81 into which this kind of coffee is put.

The pump 70, the water passage 46, the outlet 47, and the nozzle hole 53 form a flow path 82.

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 into 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 portion 72 is rotated upward around the hinge 73. In this state, the capsule 50 is placed on the setting section 65, and the handle 49 is lowered to lower the movable section 72. The guide ring 51 closely accommodates the capsule body 55 having a substantially conical shape, the nozzle 54 breaks the upper part 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 bite rib. Hold the rim 59 at the upper edge of 63. Further, when the handle 49 is rotated, the holder 48
The hook plate 68 that was loosely fitted with the holder 48 engages with the holder 48, and the guide ring 51 further descends to bite the rib 63 and the guide ring.
51 bites the rim 59 airtightly.

Next, the demitasse coffee cup 81 is placed on the placing portion 80 and the pump 70 is operated. This allows a water container (not shown)
The water in the inside is pumped by the pump 70, and is heated by the conduction heat from the heating block 41 while flowing through the spiral water passage 46,
It becomes hot water and is diffused to the coffee powder 58 in the capsule 50 from the nozzle hole 53 of the nozzle 54 through the outlet 47. Then, the hot water passes through the coffee grounds 58 and brews the coffee, then the filter 57 is used to rupture the thin portion (not shown) of the bottom portion 56 with water pressure, and the droplets are dripped from the discharge port 64 of the setting portion 65 to form a demitasse coffee cup. Stay 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 direction opposite to that before the coffee is brewed to release the engagement with the hook plate 68, and the handle 49 is raised. The lower end of the guide ring 51 and the rim 59 of the capsule 50 that has been bitten by the bite rib 63 are released, but the capsule 50 is tightly pressed into the inner surface of the guide ring 51 by water pressure.
Rises with the guide ring 51. Due to this rise,
Hook plate 68 fixed at a distance smaller than the diameter of the rim 59
The rim 59 comes into contact with. 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 part 72 also rises,
The protrusion 78 pivotally supported by the movable portion 72 moves the contact portion 79 to the movable portion.
Rotate the locking rod 75 counterclockwise while making contact with 72,
Then, the exclusion fitting 74 pivotally supported by the locking rod 75 is pulled. As a result, the capsule 50 that has fallen from the guide ring 51 to the setting portion 65 is pressed by the excluding metal fitting 74 to move from the setting portion 65 to the inclined portion 66, and slides and inclines along the inclined portion 66. It falls on a saucer 69 provided below the portion 66.

Further, when the handle 49 rises, the protrusion 78 that has been engaged with the movable rod 72 by rotating the movable rod 72 is locked.
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 moved to the movable portion 72 when the handle 49 is lowered.
At the same time, the protrusion 78 also descends and pivots clockwise while contacting the locking rod 75 to get over the locking rod 75 from the pump 70 side to the capsule base 60 side.

As described above, according to the present embodiment, the capsule 50 in which the coffee powder 58 is sealed is used, and the excluding metal fitting 74 automatically removes the exuded capsule 50 in conjunction with the raising and lowering of the guide ring 51, and the saucer 69 is provided. Since it is housed inside, preparation for coffee brewing and cleaning after brewing can be performed very easily.

In the above embodiment, the coffee powder 58 as the exudate was 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 protrusion 78 is configured to interlock the guide ring 51 that moves up and down by rotating the locking rod 75 and the exclusion metal fitting 74. May be linked. Needless to say, the exudate is not limited to the coffee powder 58.

EFFECTS OF THE INVENTION As described above, according to the present invention, the set portion having the discharge port for the exudate, the lower portion which is provided above the set portion and which is opened downward, and is vertically moved up and down, corresponding to the set portion. And a storage section that is movable so as to separate and contact with each other, a flow path that communicates one end with the pressurized water injection unit and opens the other end into the storage section, a water path that is a part of this flow path, and heat generation. A heating block having a body and an exudate container housed in the storage part, and when the storage part is lowered, the opening of the storage part is a part of the set part other than the discharge port. A holder that is covered from below by a holding unit and a setting unit that holds and holds the exudate container by holding the container, and that moves up and down in conjunction with the vertically moving storage unit. And a handle fixed to this holder By operating the handle, the storage section can be moved up and down with respect to the setting section via the holder. Therefore, preparation before leaching, operation and cleaning after leaching can be performed very easily, and since the handle moves up and down in conjunction with the storage unit, holding of the container to be leached and further raising and lowering of the storage unit are possible. It can be performed continuously, and as a result, a series of operations can be performed more easily.
