The disk hole 311 of the disk 310 is provided with a supporting ball 311 of a spindle actuator 400 The tilting motion of the driper unit 300 can be realized when the spindle actuator 400 is moved up and down.

Particularly, the dripper 330 of the dripper unit 300 includes a dripper nozzle 331, a solenoid valve 332, and a solenoid motor 333, and the solenoid valve 332 is a dripper when the solenoid motor 333 operates. By adjusting the cross-sectional area of the flow path 334 formed inside the nozzle 331, water moving the flow path 334 of the dripper nozzle 331 may be discharged in the form of a water stream or discharged in the form of water droplets.

5 is an enlarged view of the spindle actuator of the coffee machine according to the present invention.

As shown in FIG. 5, the plurality of spindle actuators 400 induce a tilting motion of the dripper unit 300 to enable water injection and syrup injection of a desired shape. To this end, the plurality of spindle actuators 400 are connected to the upper edge portion of the support unit 100 and the edge portion of the dripper unit 300 to be spaced apart in the circumferential direction.

For example, the plurality of spindle actuators 400 includes a driving motor 410, a lifting cap 420, and a support ball 430, where the driving motor 410 is provided with a rotating rod 411 to support the unit. Is installed at the upper edge portion of the 100, the lifting cap 420 is screwed to the front end of the rotary rod 411, the support ball 430 is spin-coupled to the lifting cap 420 is a dripper unit 300 It is inserted into the edge groove (311) of.

Therefore, among the three spindle actuators 400 according to the embodiment of the present invention, when the height of one of the spindle actuators 400 is set low and the height of the other two spindle actuators 400 is high, the spindle actuator of the low height When the disk 310 is inclined toward the position 400, and such a series of operations are performed continuously, water and syrup may be sprayed at a desired angle by the tilting motion of the disk 310.

In the present embodiment, the plurality of spindle actuators 400 are configured as three spindle actuators 400 which are spaced apart at intervals of 120 degrees on the upper edge of the support unit 100, but more precisely tilting movement of the dripper unit 300. In order to derive, the plurality of spindle actuators 400 may be composed of four or more, in which case, the spacing between the plurality of spindle actuators 400 may be disposed below 120 degrees.

Figure 6a is an enlarged view of the syrup unit of the coffee machine according to the present invention, Figure 6b is an enlarged view showing a screw feed tube and a screw motor of the coffee machine according to the present invention.

As shown in Figure 6a to 6b, the syrup unit 500 is a configuration for supplying the syrup to the container, the syrup nozzle in the lower portion of the dripper unit 300 to be linked to the tilting movement of the dripper unit 300 unit 540 is disposed.

That is, the syrup unit 500 is a syrup housing 510 mounted to the support unit 100 and a screw transfer pipe 520 mounted in the syrup housing 510 through a screw 521 to transfer the syrup supplied to the inlet. And a screw motor 530 for operating the screw 521 and a syrup nozzle 540 having a through hole 541 connected to the screw transfer pipe 520 through the syrup tube 550 and having water penetrated therethrough. do.

Thus, when the syrup is introduced into the inlet of the screw transfer tube 520, the syrup injected into the screw transfer tube 520 is moved to the syrup tube 550 by the rotation of the screw 521 of the screw transfer tube 520, the syrup nozzle Through 540 may be put into the receiving container. At this time, the powder hopper 200 is rotated to one side of the support 120 through the rotating means 140, so that the syrup is accommodated in the syrup nozzle 540.

Hereinafter, the operation of the present invention will be described.

After mounting the filter in the powder hopper 200 accommodates the coffee powder. When the coffee powder is accommodated in the powder hopper 200, the user selects between the drip coffee mode and the Dutch coffee mode.

When the drip coffee mode is selected by the user, the powder detection sensor 600 measures the height of the coffee powder accommodated in the powder hopper 200, and when the height of the coffee powder is measured by the powder detection sensor 600, The powder sensor 600 is rotated to the outside of the powder hopper 200 by the spin motor 610, the spindle actuator 400 is moved up and down in consideration of the height of the measured coffee powder, powder hopper ( The height of the dripper unit 300 relative to 200 is adjusted.

Subsequently, when the solenoid motor 333 is operated, the solenoid valve 332 completely opens the flow path 334 of the dripper nozzle 331 so that the water is discharged in the form of a stream, where the water in the form of the stream is in a desired shape. The operation of the plurality of spindle actuators 400 is controlled to be moved. Then, when the desired amount of coffee is extracted, by operating the rotary motor 141 of the hopper holder 210 to rotate the powder hopper 200 to one side, by controlling the operation of the spindle actuator 400, the syrup nozzle ( 540 allows the syrup to be introduced into the container in the desired shape.

Meanwhile, when the Dutch coffee mode is selected by the user, the height of the coffee powder accommodated in the powder hopper 200 is measured by the powder sensor 600, and the powder hopper 200 is measured by the powder sensor 600. When the height of the coffee powder is measured, the powder detection sensor 600 is rotated to the outside of the powder hopper 200 by the spin motor 610, the spindle actuator 400 in consideration of the height of the measured coffee powder, It moves downward, at this time, the height of the dripper unit 300 relative to the powder hopper 200 is adjusted.

Subsequently, when the solenoid motor 333 is operated, the solenoid valve 332 partially opens the flow path 334 of the dripper nozzle 331 so that the water is discharged in the form of droplets. Operation of the plurality of spindle actuators 400 is controlled to be moved.
