  • Patent number: 11517137
    Abstract: Provided is a coffee vending machine including: a plurality of capsule stacking parts arranged in a lattice form to stack capsules therein in a first direction, a capsule feeding unit disposed at the centers of the bottoms of the capsule stacking parts to feed the capsules quantitatively, a coffee brewing part for seating the capsule fed from the capsule feeding unit, feeding water to the capsule, and brewing coffee to be provided for a consumer, and a cup discharging part for discharging a cup in which the coffee is contained to the outside. The coffee brewing part allows the capsule to be seated onto a seating groove when first and second portion seating parts are adjacent thereto or contacted with each other and allows the capsule to be freely fallen through a space formed between the first and second portion seating parts when they are spaced apart from each other.
