Title:
DRIP COFFEE DEVICE CAPABLE OF FURTHER ENHANCING COFFEE TASTE WITH FAR INFRARED RAYS EMITTED FROM CERAMIC POTTERY
Document Type and Number:
WIPO Patent Application WO/2023/204343
Kind Code:
A1
Abstract:
The present invention relates to a drip coffee device, which prevents adulteration by harmful substances due to resin since all containers coming in contact with high-temperature hot water fed therein are formed of ceramic pottery, allows far infrared rays emitted from ceramic to come in contact with the hot water so as to greatly enhance the taste of drip coffee, and, specifically, allows constant micro vibrations to be generated at piercing needles when drip micro-holes are formed through the bottom surface of a water-drip container, so as to smoothly separate the piercing needles from the drip micro-holes, and thus can greatly lower the defect rate of the drip micro-holes.
