Description

Hand drip coffee extraction device {A hand-drip coffee machine}

The present invention relates to a hand drip coffee extraction device, and more particularly, to a device configured to allow a hot water nozzle and a dripper to move relative to the three-axis direction in the space to reproduce the operation of the barista extracting hand drip coffee. will be.

Espresso coffee commonly provided in coffee shops has the advantage of being able to provide a large amount of coffee in a short time by brewing quickly using pressure. Due to these characteristics, espresso coffee has enabled the popularization of ground coffee, and most coffee shops provide coffee drinks based on such espresso coffee. However, since espresso coffee is usually extracted with high-pressure steam of 9 atm or higher, it has a disadvantage that even the bad ingredients of the beans are extracted and the bitter taste is too strong. People who want to enjoy a softer and milder coffee have recently moved to hand drip coffee or water drip coffee (Dutch coffee).

Hand drip is a method that extracts coffee with a deeper and softer taste and aroma than espresso coffee by slowly pouring hot water onto ground beans and extracting it using gravity. In addition, since the user can freely control the temperature and amount of water, the thickness of the water stream, the water pouring time, the water pouring interval, and the water pouring trajectory, there is an advantage in that coffee of various tastes and aromas can be extracted. However, this hand drip method is a coffee extraction method that is difficult to popularize because the procedure is cumbersome and time-consuming because the user must pour water to extract coffee. Recently, some coffee shops are attempting to provide hand drip coffee by baristas, but it is difficult to replace espresso coffee in terms of manufacturing time and unit cost.

The present invention is to provide a drip coffee extraction apparatus capable of automatically extracting hand drip coffee so that the hand drip coffee can be popularized. As an example of the prior art for automatically extracting hand drip coffee, Korean Patent Registration No. 10-1281648 (registered on June 27, 2013, patentee-Kyungpook National University Industry-Academic Cooperation Foundation) has a hopper in which coffee powder is accommodated, and the upper side of the hopper. A disk disposed in and formed with a screw groove extending in a radial direction, a drive motor having a rotation shaft and installed in the center of the disk, a rotor connected to the rotation shaft and extending a long groove in the longitudinal direction, and a long groove of the rotor. Disclosed is a hand drip coffee machine comprising a dripper that is slidably mounted and moves in a spiral shape along a screw groove of a disk when the rotor rotates, and a water tank for supplying water to the dripper. This conventional hand drip coffee machine is implemented so that hand drip coffee can be extracted similar to the way Barastar extracts hand drip coffee.

However, in the conventional hand drip coffee machine, there is a problem that the drop trajectory cannot be changed because the hot water drop trajectory is implemented as a screw groove of the disk. In other words, there is a problem that this cannot be reflected even though the hot water drop trajectory that can give the best taste for each type of coffee beans is different.

In addition, in the conventional hand drip coffee machine, components such as the drive motor 300, the rotor 400, and the sliding piece 530 for inducing the transfer motion of the drip nozzle 520 are the upper part of the hopper, that is, hand drip coffee. Since it is located on the top of the machine, the overall center of gravity is located on the top of the machine, so there is a problem of structural instability.

In addition, in the conventional hand drip coffee machine, the rotor 400 and the sliding piece 530 are located vertically above the hopper, and a part of the area of the disk 200 is open to the screw groove 210, so that the sliding motion There is a concern that foreign substances or lubricating oil from the rotor 400 and the sliding piece 530 fall into the hopper.

Hand drip is a method of extracting coffee by pouring hot water several times over the ground beans after roasting. As described above, there has been a proposal for an idea for extracting hand drip coffee, but the hand drip coffee extracting device has not been widely spread. There may be various reasons, but one factor may be that the technology that can reproduce the barista's hand skills that influence the taste of coffee has not been developed.

The barista fine-tunes the different elements of the water pour to achieve the best coffee taste. These factors may be, for example, the thickness of the water stem, the direction of the swing (clockwise or counterclockwise), the water drop (the difference in height between the drip pot and the dripper), the amount of water in a single pour.

The present invention relates to a device capable of reproducing the hand motion of a barista extracting hand drip coffee, and more particularly, to a device configured to reproduce the motion of a drip pot dropping hot water onto a dripper.

Referring to FIG. 1, in the coffee extraction process, the barista pours water while moving so that the spout of the drip pot P draws a circular trajectory (T) on a dripper (D) containing ground coffee beans. The barista not only moves the drip pot (P) in a circle on a horizontal plane, but also adjusts the drop of water falling on the dripper (D) while moving up and down.

The present invention proposes a device capable of reproducing the hand motion of a barista extracting hand drip coffee as it is.

<First Example>

2, a hand drip coffee extraction apparatus according to an embodiment of the present invention includes a nozzle (N) for dropping hot water onto a dripper (D) and a transfer unit 10 for operating the nozzle (N). do. Although not shown, the hand drip coffee extraction device further includes a hot water supply device providing hot water to be dropped through the nozzle N.

The nozzle (N) is disposed above the dripper (D) so as to supply hot water above the dripper (D). The transfer unit 10 is configured to transfer the nozzle N in the three axial directions of the X-axis, the Y-axis, and the Z-axis in space. The transfer unit 10 is configured to not only transfer the nozzle N on the horizontal plane (XY plane), but also transfer the nozzle N in the vertical direction (Z-axis direction), so that the barista moves the drip pot. Can be reproduced as it is. The transfer unit 10 may include at least three actuators for providing a transfer driving force in each of the three axial directions and power transmission parts for transferring power of these actuators to the nozzle N.

<Second Example>

In the first embodiment of the foregoing, the hand drip coffee extraction apparatus is a method in which water is poured for coffee extraction by transferring the nozzle N while the dripper D is placed on the floor, and the nozzle N and the dripper D You can also reproduce the barista's hand drip coffee brewing motion by operating both and causing a relative movement between the two.

For example, the hand drip coffee extraction apparatus according to another embodiment shown in FIG. 3 includes a first transfer unit 11 for operating the nozzle N and a second transfer unit 12 for operating the dripper D. Includes. The first transfer unit 11 and the second transfer unit 12 are configured to operate each of the nozzles N and the drippers D in one or more axial directions in space, respectively.

I can.

A drip server (S) for storing the extracted drip coffee is placed under the dripper (D), and it is not preferable that the dripper (D) and the drip server (S) placed integrally are transferred in the horizontal direction. This is because the coffee contained in the drip server (S) may spill or the dripper (D) may tilt and fall (hereinafter, “dipper (D)” refers to the entire set of drip devices including the drip server (S)). Used as a term). Therefore, it is preferable that the dripper (D) constitutes the first transfer unit 11 and the second transfer unit 12 under conditions constrained so that horizontal transfer is not performed.

As an operation for conventional hand drip coffee extraction, the nozzle (N) is required to draw a circle of various radiuses large and small on a horizontal plane with respect to the dripper (D). This circular motion may be implemented in the first transfer unit 11 for operating the nozzle N. That is, it may be composed of at least two or more actuators and power transmission parts for transmitting the operation of these actuators to the nozzle (N). However, when a two-axis power transmission device is implemented in the first transfer unit 11, the device configuration becomes complicated, and the number of parts disposed above the dripper D may increase and become heavier.

In order to generate a relative circular motion between the nozzle (N) and the dripper (D) under the condition that the horizontal transfer of the dripper (D) is limited, the first transfer unit (11) moves the nozzle (N) in a uniaxial direction. Most preferably, the second transfer unit 12 is configured to rotate the dripper D. That is, the second transfer unit 12 is configured to rotate the dripper (D) in place and up and down.

As shown in Fig. 3, the first transfer unit 11 is configured to transfer the nozzle N in the radial direction (R direction) of the dripper D, and the second transfer unit 12 is a dripper (D). It is preferable that it is configured to be able to raise and lower the rotation (θ direction) and the vertical direction (Z axis direction) with respect to the central axis.
