The present invention relates to a hand drip coffee automatic extracting apparatus.

Hand Drip Coffee Extractor is a hand drip kettle or dripper that extracts coffee by dripping water or water into coffee bean. It is a device that extracts coffee and extracts coffee beans Therefore, various kinds of coffee bean extracting apparatuses have been proposed for wetting water and coffee beans evenly.

As a conventional technique, in Patent Document 10-2014-0065610, a coffee filter having a plurality of extracting coffees housed in a rotating turntable having a multi-layer structure is placed, and a coffee extracting device for pouring water with a hand dripping kettle, An extraction device using a filter is known.

As shown in FIG. 1, there are two water supply nozzles fixed at a predetermined position and an extracting device for rotating the coffee-cup accommodating cup in a fixed posture at a lower position. However, There was a limit to partially wet the coffee beans rotating.

As shown in the prior art of FIG. 2, it is difficult for the water supply nozzle at a predetermined position to rotate around the coffee beans contained in the receiving cup. However, in such a fixed posture, it is difficult to wet the water with the coffee beans evenly.

The prior art shown in FIG. 3 shows that the conventional art of FIG. 2 is improved, and the dripper is formed so as to be able to change the angle or the angle, but not only the contact of the water-ground coffee is limited, There is a limit to contact.

The conventional art of FIG. 4 has a disadvantage in that a large amount of water is supplied to a portion of the coffee bean having a small amount of coffee, which is rotated around the coffee bean receptacle at the same time as the water supply nozzle itself rotates.

FIG. 5 is a view showing a state in which a water supply device formed by installing a water tube 30 instead of a material utilizing a 3D print formed to spray a material three-dimensionally is formed so as to be dripped while being moved or rotated at various inclination angles, The means for adjusting the speed of the water droplet or the water droplet, which is one of the elements for determining the water content, is not provided.

Thus, conventional hand drip coffee extracting apparatuses are not sufficient to evenly drip water droplets or water droplets into the coffee beans, and the water dispenser can not control the water to cope with the conditions of the coffee beans, So the taste of the coffee is different from that of using a hand drip kettle.

Therefore, there is a demand for a hand drip coffee extracting apparatus of improved configuration in which the condition of the delicious hand drip coffee is improved by controlling the speed of the water to be dripped and by improving the material time.

So that the water droplet trajectory is formed from the central portion to the edge of the coffee so as to wet the entire upper surface evenly with water, and furthermore, the water droplet trajectory overlaps the center portion where the coffee beans are contained more and forms more dripping water, Which is capable of extracting coffee of the hand drip coffee extracting apparatus of the present invention.

In order to achieve this object, the present invention is characterized by comprising a rotating plate 102 coupled to a rotating shaft of a decelerating motor 1 (101);

A control unit 123 configured to control a reciprocating speed of the hand drip kettle 160, a reciprocating distance, a hand drip kettle inclination, and a rotation speed of the coffee cup 170 accommodating the coffee beans 180;

모양을 형성할 수 있도록 구성된 것을 특징으로 하는 핸드드립커피 자동추출장치에 관한 것이다.The trajectory of water droplets or water drips on the coffee beans contained in the cup by the control of the control unit 123 and the adjustment of the adjusting screw 131

The present invention relates to a hand drip coffee automatic extracting apparatus.

In the present invention, the rotation of the deceleration motor 2 (111) is controlled by the controller 123 to rotate in the category of 20-50 times per minute, and the deceleration motor 2 (111) - the pedestal 113 - the coffee cup 190 A predetermined amount of coffee beans 180 accommodated in the bean coffee receiving cup 170 rotates together with the bean coffee receiving cup 170 and is heated by a hot water droplet Or extraction in contact with the water stream.

The rotary motion of the rotary plate 102 coupled to the rotary shaft of the deceleration motor 1 101 is converted into a horizontal motion by the crank arm 105 and the connection arm 107 to be connected to the body 120 connected to the connection arm 107, The upper horizontal fluid 150 is reciprocated 20 to 50 times per minute.

A slope pedestal 153 is formed at an upper end of the reciprocating horizontal fluid 150 so as to adjust the slope by a cylinder 155 and a hand drip kettle 160 is detachably attached to the upper surface of the slope pedestal 153 A formed fixed bed is formed. The detachment of the hand drip kettle is formed so that the kettle does not separate because the kettle is tilted so that it is tilted by engagement with the shape of the fitting.

The hot water in the hand drip kettle 160 is dripped through the spout 165 into the coffee beans 180 received in the lower coffee bean receiving cup 170, And is dripped by the flow by the upper surface diameter (a) of the coffee bean.

The trajectory of water dripped in the spout 165 to the horizontal reciprocating movement of the hand drip kettle 160 and the rotation movement of the coffee bean receiving cup 170 is as shown in Figure 6, Drew in the direction of the arrow, dive again in the direction of the second color arrow, then dive in the direction of the arrow 3, then dive in the direction of the arrow 4, then dive in the direction of arrow 5 and then dive in the direction of arrow 6 The drip trajectory of the predetermined time is completed by reaching the starting point.

This is due to the correlation between the reciprocating movement and the horizontal movement, but there is a difference in the number of trajectories. However, when the parabola is drawn at the coffee bean edge (181), the coffee bean moves to the edge of the coffee bean (181) The basic trajectory for repeating the trajectory to the edge 181 of the coffee bean is the same.

The drip trajectory is a special constitution of the present invention, that is, when drip water is horizontally reciprocating at a predetermined speed in a diameter distance passing through the center of the top surface of the coffee bean, while the coffee contained in the bean coffee accommodating cup rotates at a predetermined speed And the coffee beans are made to meet each other so that more water is dripped toward the central portion where the amount of coffee beans is large, so that water is uniformly distributed throughout the entire coffee beans. Since the extraction is sufficiently performed by the constant drip trajectory, the deep taste and the uniform taste of the coffee bean can be extracted.

The water dripped in the present invention may be a water droplet or a water droplet. If the slope of the hand drip kettle is relatively small, the water droplet may be generated. However, if the slope is large, the water may be dripped.

The control unit 123 controls the cylinder 155 to adjust the inclination of the hand drip kettle 160 by adjusting the inclination angle of the inclined pedestal 153. As the inclination of the hand drip kettle 160 increases, The drip speed of the water becomes faster.

6) depending on the amount of coffee contained in the coffee bean receiving cup 170, the present invention can be applied to the horizontal liquid body 150 (see FIG. 6) depending on the size of the coffee top surface diameter a A plurality of link holes 103 are formed in the rotating plate 102 coupled to the rotating shaft of the decelerating motor 101 so that the crank arm 105 and the link hole 103 Since the link point 104 is moved to the link hole at the proper position to form a link point, the hinge-coupled link point 104 can be adjusted by changing the link point. As the midpoint of the reciprocating motion moves due to the link point change, The adjustment screw 131 is formed so that the line 177 can be aligned and moved so that the position of the coffee bean intermediate line 177 can be shifted by horizontally moving the speed reduction motor 2 111 .

모양으로 형성되도록 함으로써 원두커피(180)의 양이 더 많이 수용된 중심부로 갈수록 가장자리보다 더 많은 물이 드립되는 효과가 있으며, 이와 같은 드립되는 물방울 또는 물줄기에 의해 수용된 원두커피 전체에 물을 고르게 적시도록 함으로써 충분하면서 균질의 원두커피 추출을 가능하도록 해 주는 효과가 있으며,The hand drip coffee extracting apparatus of the present invention extracts coffee beans from the spout 165 of the hand drip kettle 160 by the horizontal reciprocating motion of the hand drip kettle 160 and the rotating movement of the coffee bean receiving cup 170 The drip trail of water droplets or water dripped in the coffee beans 180 accommodated in the

So that more water is dripped from the edge toward the central portion where the amount of the coffee beans 180 is more increased. In order to evenly wet the whole coffee beans accommodated by the dripping water or the water drip, Thereby making it possible to extract a coffee bean having a sufficient homogeneity,

In addition, since the extraction is sufficiently carried out from the whole coffee beans, it is possible to obtain an extracted coffee having a good taste and extract it with a drip trail of a certain pattern, thereby reproducing the deep taste and uniform taste of the coffee beans.

In addition, according to the present invention, the link point 104 of the crank arm 105 is moved according to the change in the distance a of the top surface of the coffee bean according to the amount of the ground coffee, and the bean coffee center line 177 is moved by the adjusting screw, It is possible to adjust the drip section according to the upper surface diameter distance (a).

The present invention also controls the slope of the hand drip kettle 160 by the cylinder 155 according to the type of coffee, the amount of coffee, the desired taste of the coffee, It is possible to control the amount of the liquid.

6 is a schematic view showing the configuration of an embodiment of the present invention in an easy-to-understand manner. 1, a horizontal fluid 150 that flows linearly and horizontally is formed on an upper portion of the main body 120, and a plurality of motors 110, 120, And the rotational motion of the deceleration motor 1 is switched to the horizontal motion so that the horizontal fluid 150 is formed to be reciprocated horizontally while moving closer to the coffee bean receiving cup 170. [ To the horizontal motion is a general technique and a detailed description thereof is omitted)

A plurality of link holes 103 having different distances from the center are formed in the rotary plate 102 and the flow width of the horizontal fluid 150 is adjusted by changing the link point 104 to which the crank arm 105 is coupled, And the flow width of water droplets or water droplets dripping from the spout 165 of the drip kettle 160 is adjusted.

The reason for controlling the drip flow width is that the height varies depending on the amount of the coffee beans 180 accommodated in the bean coffee cup 170, and the diameter of the top surface of the bean coffee (the horizontal line according to the height in the drawing) So that the water dripped from the spout 165 is also adjusted to the same width in accordance with the change in the diameter of the top surface of the circumferential coffee.

In order to control the variation of the width of the horizontal flow, the center line 177 of the ground coffee 180 is adjusted to be aligned with the center of the horizontal flow of the drip, And an adjusting screw 131 for horizontally moving the decelerating motor 2 (111) vertically coupled by the receiving cup 170 - pedestal 113 - decelerating motor 2 (111).

The adjusting screw 131 is formed to penetrate through the main body 120 and the deceleration motor 2 pedestal 132 so as to allow the deceleration motor 2 111 provided to be able to flow on the deceleration motor 2 pedestal 132 to flow horizontally And it is a matter of course that the flow can be performed by various methods using conventional techniques.

In addition, the present invention is provided with an inclined pedestal 153 formed to mount a hand drip kettle 160 at the upper end of the horizontal fluid 150. The slope pedestal 153 is provided with a fixing base 154 for detachably attaching the hand drip kettle 160 and is provided with a bar 158 for mounting the spout 165 therein.

The inclined pedestal 153 of the present invention is formed to be folded by the hinge portions 156 and 157 and is configured to adjust the inclination of the hand drip kettle 160 by the cylinder 155.

In this way, the amount of water (velocity amount) dripped into the coffee bean can be controlled by adjusting the inclination of the hand drip kettle 160.

The present invention improves the taste of the coffee bean extracted by optimizing the reciprocating cycle of water dripped in the hand drip kettle, the speed of water dripped, the number of rotations of the coffee beans 180 contained in the coffee bean receiving cup 170, The control unit 123 may be controlled manually or automatically. In case of manual, it is adjusted one by one, and when it is automatic, it is controlled automatically by the optimization program inputted to the microcomputer.

Fig. 7 shows a state in which the inclined pedestal 153 is horizontal, and it is mainly in such a horizontal state before and after the extraction.

8 is a graph showing a representative drip trail formed on the top surface of the ground coffee of the drip water for a predetermined time. The drip water is circulated between the edges 181 passing through the center of the ground coffee 180 housed in the ground coffee receiving cup 170 And at the same time, the bean coffee receiving cup 170 rotates, so that the drip trajectory can be obtained.

FIG. 9 shows the order of the drip trajectory. It is dribbled in the direction of arrow 1 at the starting point S, dribbled in the direction of arrow 2 again, dribbled in the direction of arrow 3, Drips in the direction of arrow 5, then dives in the direction of arrow 6, reaches the starting point, and completes one trajectory for a predetermined time.

This trajectory shape may cause a difference in the number of trajectories depending on the correlation between the reciprocating motion and the horizontal movement. However, when the parabola is drawn at the coffee bean edge 181, the coffee bean goes to the coffee bean edge 181 through the center point, It is the same to repeat the drip trail to the bean coffee edge 181 through the center point.

As can be seen from this drip trajectory, the trajectory becomes more and more overlapped with the center part. This is because by dripping a lot of water in the central part containing more coffee beans, So that the extracted coffee has a good concentration and taste.

Figure 10 shows a schematic plan view of an embodiment of the present invention.

The present invention is not limited to the above-described embodiments, but includes various embodiments that can be practiced in the ordinary skill in the art.
