And a drip portion disposed on the upper side of the hopper portion and including an XY axis feeding portion for moving the other end of the tube on the upper surface of the hopper in the XY axis plane.
The method according to claim 1,
A Z-axis feeder including a Z-axis motor and reciprocally moving the drip portion upward and downward within a predetermined interval in the Z-axis direction along one side of the machine body from above the hopper by a driving force of the Z-axis motor; And
And a drip locus adjusting unit adjusting a distance between the drip part and the hopper in the Z-axis direction so that a trajectory of water falling through the other end of the tube can be set on the XY-axis plane, The coffee drip machine comprising:
The method according to claim 1,
Further comprising a controller for controlling operations of the boiler, the hot water side micro bubble generator, the cooler, and the cold water side micro bubble generator based on a predetermined input signal,
The controller automatically controls the flow path of the cold water pipe by the on / off switching valve when the operation of the boiler and the hot water side micro bubble generator is controlled to be on,
Wherein when the controller controls the operation of the cooler and the cold water side micro bubble generator to be on, the flow path of the hot water pipe is automatically blocked by the on / off switching valve.
The method according to claim 1,
The XY-
An X-axis transferring line and an X-axis guiding line extending in the X-axis direction from one side and the other side of the drip portion and disposed so as to face each other;
A first X-axis moving member coupled to the X-axis moving member to be reciprocated in the X-axis direction along the X-axis moving line by an X-axis motor, and a second X- A second X-axis moving member moved together with the X-axis moving member and the connecting line;
A Y-axis transfer line having one end and the other end connected to the first X-axis moving member and the second X-axis moving member, respectively; And
And a Y-axis moving member coupled to the Y-axis transfer line by the Y-axis motor and coupled to the connection line and reciprocated in the Y-axis direction,
Wherein the tube is coupled to the Y-axis moving member such that water falling through the other end of the tube is directed into the hopper.
The method according to claim 1,
A dummy housing part is coupled to one side of the machine body,
A micro-bubble generating unit for generating micro-bubbles toward the coffee-mixing unit and spraying the micro-bubbles is provided in a lower portion of the coffee-mixing unit,
Wherein the hopper portion is rotatably provided by a hinge portion.
