Description

Apparatus for making drip coffee [0001]

The present invention relates to a drip coffee making apparatus, and more particularly, to a drip coffee making apparatus capable of automatically manufacturing a drip coffee, simplifying a structure for realizing a drip pattern for an optimum drip coffee having an excellent flavor and aroma, The present invention relates to a drip coffee making apparatus capable of easily manufacturing, assembling, and repairing, thereby improving productivity and reducing manufacturing costs.

As shown in FIGS. 1 and 2, in the conventional drip coffee making apparatus, the rotation motor 121 rotates at a low speed (10 to 30 RPM) similar to that used when manually drawing a circle in a conventional drip method. The rotation motor 121 can stop the operation with the motor regulator 116. [

The moving motor 124 uses a low-speed motor of about 10 RPM and transfers the power to the moving belt 114 using the power transmission roller 134 of the rubber product. The moving motor 124 can be rotated clockwise or counterclockwise by the motor regulator 116. [ In this way, the moving motor 124 moves the movable stage 114 to reciprocate left and right horizontal surfaces together with the rotating stage 111 installed thereon.

The rotating table 111 is driven by the rotating motor 121 and rotates the server 22 and the drier 21 placed on the rotating table 111. The moving base 114 is moved by the moving motor 124. When the position of the movable table 114 is at the 'center' position, the water drop point where the water in the water table falls is near the center of the turntable 111, that is, near the center when the server 22 and the dripper 21 are in place And when the swivel base 111 rotates, the drop point draws the smallest circle. 2, when the position of the movable table 114 is in the 'fresh' position in FIG. 2, the water drop point at which the water of the water inlet falls,

When the server 22 and the dripper 21 are put in place, the edge is the edge, and when the swivel 111 is turned, the dropping point draws the largest circle. When the rotation point 111 is continuously rotated while continuously moving the reference point from the center to the moving table 114, the falling point moves from the center to the edge, and the dropping point becomes a spiral shape from a small circle to an increasingly large circle

Further, in the conventional drip coffee making apparatus, the drip server rotates and the moving base 14 moves, but the nozzle moves back and forth.

However, the conventional drip coffee making apparatus as described above has a disadvantage in that the size of the drip coffee making apparatus is increased due to a large space occupied for moving the moving die or the nozzle, and a part operated when the server and the nozzle rotate or move back and forth There is a problem in that it is difficult to design a small and lightweight structure because of its complicated structure because of its two locations, its cost is high, maintenance and manufacture are difficult.

Therefore, the definition of this term should be based on the entire contents of this specification.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know completely.

3 is a front view of the drip coffee making apparatus of the present invention.

The drip coffee making apparatus 100 includes a boiler module 10, a transmission 20, a hot water supply tube 30, a main frame 40, a nozzle 50, a drier 60, a server 70 ), And a heating bed (80).

The boiler module 10 stores water and heats the heated water to a predetermined temperature and discharges hot water to the nozzle 50 through a hot water supply tube 30 by a built-in pump (not shown) . It is needless to say that the flow rate of the pump can be adjusted by controlling the output of the pump by a control unit (not shown).

The transmission device 20 is one of the features of the present invention and is configured to realize the drip pattern by rotating the nozzle 50. A detailed description will be given later.

The dripper 60 is a funnel-shaped tool for dripping, placing a filter made of paper, metal or cloth on the dripper, filling the ground coffee with the ground coffee, and extracting hot water. The drifter may be formed in a reverse trapezoidal shape or a conical shape.

The server 70 is a container for receiving the filtered coffee when the coffee is extracted in a dripping manner, and is made of a material such as glass, fragrance or the like which is resistant to heat.

The heating bed 80 is a device for preventing the extracted coffee from being cooled, and is in contact with the server to transmit heat.

4 is a flowchart showing movement of the nozzle in the Y-axis direction according to the first embodiment of the present invention

As shown in the figure, the rotary shaft 47 fixed to the first motor 43 is fixed to the end surface of the main frame 40. Therefore, when the first motor 43 is driven, the rotation shaft 47 fixed to the first motor 43 rotates, and the main frame 40, which is mutually fixed with the rotation shaft 47, The nozzle 50 fixed to the main frame 40 is also rotated.

5 is a flowchart showing the movement of the nozzle in the X-axis direction according to the first embodiment of the present invention.

The nozzle 50 is fixed to a rotary shaft 45 rotatably coupled to one side of the main frame 40 on the upper side of the drier 60. A gear 42a is fixed to one end of the rotary shaft 45 And the gear 42a is engaged with the timing belt 41. As shown in Fig.

The second motor 44 is fixed to the other side of the main frame 40. The rotation axis 46 of the second motor 44 is rotatably coupled to the main frame 40, At one end, a gear 42b is fixed, and the gear is engaged with the timing belt 41. [

When the second motor 44 is operated, the rotating shaft 46 fixed to the second motor 44 rotates. When the rotating shaft 46 rotates, the rotating shaft 46 is fixed to the rotating shaft 46 The timing belt 41 coupled to the gear 42b also rotates while the gear 42b rotates so that the gear 42a interlocked with the timing belt 41 rotates and the rotation shaft 45 also rotates. Therefore, the nozzle 50 fixed to the rotary shaft 45 is rotated in the X-axis direction about the Y-axis.

In the drip coffee making apparatus having such a configuration, the nozzle rotates in the Y axis direction about the X axis by the first motor, and the nozzle rotates in the X axis direction about the Y axis by the second motor. Therefore, when the driving periods of the first and second motors are the same, the trajectory of the nozzle end is drawn in a circle (when the driving amplitude is the same) or an ellipse (when the driving amplitude is different), which is a closed curve on the X-Y plane. In addition, if the driving periods are not the same, the nozzle is turned by an open curve, so that a drip pattern corresponding to the trajectory of the nozzle end can be realized as shown in FIG.

It is needless to say that the nozzle trajectory can be adjusted by controlling the rotation of the first and second motors by a control unit (not shown).

7 is a side view showing a second embodiment of the present invention.

In the first embodiment as shown in Fig. 6A, the nozzle and the timing belt are rotated by the gear and the timing belt. In this embodiment, however, the link structure is adopted as shown in Fig.

The lifting links 48a and 48b are fixed to the rotating shafts 45 and 46. The lifting links 48a and 48b are rotatably supported by the hinge links 48a and 48b, Lt; / RTI >

When the second motor 44 is driven to rotate the rotating shaft 46, the lifting link 48a is moved up and down in conjunction with the rotating direction of the rotating shaft 46, and the lifting link 48a The driving link 49 rotatably hinged to the driving link 49 also ascends and descends while lifting and lowering the lifting link 48b hinged to the driving link 49. [

Accordingly, the rotary shaft 45 fixed to the lifting link 48b also rotates, and the nozzle 50 fixed to the rotary shaft 45 also rotates to draw the drip pattern.

Needless to say, the gear and timing belt and the link structure for actuating the nozzle can be replaced by a linear motion mechanism.

The present invention adopts the above-described configuration, so that it is possible to easily and efficiently extract and taste the drip-type coffee even if a general person is unfamiliar with the drip-type coffee extraction. In addition, the main frame formed on the upper side of the drip- It is possible to reduce the size of the drip coffee making apparatus compared to the conventional drip coffee making apparatus and it is easy to manufacture, control, assemble, and repair due to the simple structure, thereby reducing production cost, minimizing defective products, Since standardization is possible, mass production of drip coffee making equipment is possible. As a result, raw materials and labor costs are reduced, product defects are reduced, productivity can be improved, production can be increased, and productivity can be further improved as the cycle time of the assembly process is shortened.

In addition, it is possible to design a compact and lightweight design, and the drip pattern can be selected and used according to the user's preference regardless of the shape of the droplet.
