2. Description of the Related Art Japanese Patent Laid-Open No.
As disclosed in Japanese Patent No. 28574, a drip type in which high-temperature hot water is poured from above coffee grounds stored in a basket, and boiling that rises from a lower container to coffee grounds stored in a container provided in an upper part A siphon type that pours water,
There is a hand pouring type that pours from the top of the filter containing coffee powder with a pouring pot.

[0003] Among them, the simplest, but the most delicious coffee can be extracted by skill by hand pouring.

However, a so-called flannel filter made of cloth is optimal for the filter, and this flannel filter is always used for business such as a coffee shop.

[0005]

The reason that the flannel filter is optimal is due to the water retention effect of the flannel fabric.

[0006] The water retention effect here means a time delay phenomenon in which hot water flows through the flannel filter, does not immediately pass through the filter, stays in the fabric for a short time, and falls from the lower part of the filter after a while. I do.

[0007] This phenomenon is convenient for dispersing coffee powder immediately after pouring, and is optimal for coffee extraction.

On the other hand, this phenomenon is also a disadvantage. that is,
The large water retention effect makes the drainage worse, and even after extracting the required amount of coffee, long drops fall from the bottom of the filter, making it slower to remove the filter, which is inconvenient for coffee shops that extract a large number of coffee .

If the filter is removed in spite of the drop, the drop may adhere to the server cup or stain the table.

According to the present invention, the amount and time of the drops falling from the lower portion of the cloth filter are reduced, the service of the coffee is accelerated, and the stains in the vicinity are prevented.

[0011]

SUMMARY OF THE INVENTION The present invention provides a hot water supply tank, a pouring mechanism for pouring hot water in the hot water supply tank from a nozzle, a cloth filter for accommodating coffee powder, and a cloth filter holding the cloth filter. A holder that horizontally moves below the nozzle and a movable mechanism provided in association with the holder, wherein a cup is placed below the cloth filter, and pouring water of the nozzle is poured into coffee powder to extract coffee. The movable mechanism inclines the holder.

Further, the movable mechanism operates after the pouring operation is completed.

The movable mechanism is executed by rotation of a cam.

Further, the movable mechanism tilts the take-out side of the holder at a low angle.

4) A rail receiver (15) (15) provided with a motor (16) provided on the rear side of the rail receiver, and a holder driven by the motor to lift the rear side of the rail receiver (15) (15). A movable mechanism (18) including a cam (17) for inclining the cradle (13) is provided.

The motor (16) of the movable mechanism (18)
Although not shown in detail, the longitudinal direction of the cam (17) is set to the horizontal position when the pouring is not performed, and the cam (1) is
7) The microcomputer controls the longitudinal direction to be the vertical position, and in particular, 5 to 1 after the pouring operation is completed.
After a lapse of about 0 seconds, the motor is driven to bring the cam into a vertical state, and this state is maintained for a predetermined time.

When the holder (10) has been tilted for a predetermined time, the motor is driven again to return the cam (17) to the predetermined position.

The holder (1) by the movable mechanism (18)
The inclination of 0) is set so that the take-out side of the holder (10) is low and the back is high.

(19) (19) is the accommodation hole (11)
(11) A flannel-made cloth filter which is detachably held, and the side edges and the lower side edge are sewn together to form a bag-like shape, and coffee powder is stored therein.

As a result, corners are formed on both sides of the lower side edge of the cloth filter (19), and the stitches are in the same direction as the direction in which the cloth filter (19) is taken out (the direction in which the holder is taken out) when the cloth filter (19) is mounted on the holder. .

Next, the operation will be described. After the holder (10) is pulled out in advance and the cloth filter (19) containing the coffee powder is attached to the accommodation hole (11), the holder (10) is moved to position the center of the cloth filter immediately below the nozzle (8). Let it.

When the pouring button (not shown) is operated in this state, the boiling water in the hot water supply tank (5) is poured from the nozzle (8), and the nozzle is turned by the drive unit into the shape of "". It turns as if drawing, and the pouring water spreads all over the coffee grounds.

[0025] The extract obtained by pouring coffee grounds is
After a certain time delay due to the water retaining action of the cloth filter (19), and the crushing is performed, as shown in FIG. 4, it falls from the seam (B) and around the seam and is stored in the cup (C).

When the pouring operation is completed and a predetermined time has elapsed,
The motor (16) is driven by the output of the microcomputer, and the cam (17) whose longitudinal direction is at the horizontal position is rotated by about 90 degrees to the vertical position, and the rear side of the holder (10) is lifted, and the holder (10) is lifted. Is tilted so that the front side is low and the back is high.

Due to the inclination of the holder (10), the front end (b) of the seam (B) of the cloth filter (19) becomes lowest as shown in FIG. Then, the extract liquid permeating the cloth filter and the extract liquid near the seam of the cloth filter are collected at one end, and immediately dropped into the cup (C).
