Apparatus and method for extracting dutch coffee

A Dutch coffee extraction apparatus comprising:

• an upper main body frame;
• a lower main body frame which is formed on a lower portion of the upper main body frame and has a width shorter than that of the upper main body frame;
• a side frame which connects the upper main body frame and the lower main body frame with each other;
• a water tank which is disposed inside the upper main body frame and has a cover provided on an upper portion thereof to store water therein;
• a filtering container which is disposed at both sides of the lower main body frame, is connected with the water tank via a nozzle to receive water from the water tank, and stores ground coffee thereon;
• an extracted liquid storage container which is disposed under the filtering container to store an extracted liquid thereon;
• and
• a digital operation unit which is formed on one side of the side frame,
• wherein the filtering container comprises:
• a container main body which is formed in a cylindrical shape, penetrating from top to bottom;
• a distributing means which comprises:
• a water supply surface which is formed on the upper end of the container main body and is downwardly inclined from the center toward the side surface so as to spray water supplied through the nozzle into the container main body;
• a water flow blocking surface which is upwardly inclined from the end of the water supply surface toward the side surface;
• a plurality of water passing holes passing through the top surface and the bottom surface of the water supply surface;
• and a center drop inducing means which is formed on the top surface and the bottom surface of the water supply surface at a point spaced from the center of the water supply surface toward the outer circumference by a predetermined distance, and protrudes in an annular shape so as to prevent the supplied water from flowing down along the wall surface of the filtering container;
• a filtering container upper cover which is formed to cover the upper portion of the distributing means and has a water supply portion formed thereon to receive water from the water tank;
• and
• a filtering container lower cover which has an upper portion inserted into the inner surface of the lower portion of the container main body, and a lower portion formed in a funnel shape.
