This invention provides a coffee maker having a top housing (2) connected to a bottom housing (3) via a plurality of connecting elements (4) such that the top housing is enacted above the bottom housing; a water tank (1) positioned on top of the top housing; a carafe (5) to be placed under the top housing, the carafe has an upper part having a brewing cone (51); and a rotating spout (6) located at the bottom of said top housing and above the carafe for pouring hot water into the carafe.

A beverage brewer spray apparatus includes a lid, one or more dispersal members, and a skirt. The lid has obverse and converse surfaces, with at least one recessed region in the obverse surface. The dispersal members extend from the converse surface at open proximal ends. The skirt has a proximal end fixed to and extending outward from the converse surface of the lid. Each dispersal member has a sidewall and a distal end defining an interior of the dispersal member. The sidewall has apertures arranged in a distal section of the sidewall. The lid has through-holes formed between the obverse and converse surfaces, and the dispersal members are fixed to the converse surface such that the through-holes provide fluid communication from the obverse surface of the lid to the apertures through the interiors of the dispersal members. The apertures are configured to direct liquid outward from the dispersal members.

A beverage extracting device is provided that includes an extracting part including an installing space in which a beverage capsule is installed; an opening and closing part connected to the extracting part, for opening or sealing the installing space; a link part connected to at least one from among the extracting part and the opening and closing part; and a perforating part for moving reciprocally according to the movement of the link part so as to perforate the beverage capsule.

A beverage brewer includes a brewing material holder and a movable water-dispensing member configured to receive a flow of liquid and including ports configured to release received liquid into the brewing material holder. The brewer can also include a water-dispersing assembly disposed above the brewing material holder to receive the flow of liquid. The movable water-dispensing member can be couplable to the water-dispersing assembly to receive the flow of liquid. The water-dispersing assembly can include a reservoir having an outlet, such as a funnel. The movable water-dispensing member can be configured to move, such as to rotate, due to a force of pressure provided by the flow of liquid. The force of pressure provided by the flow of liquid can be caused, for example, by the weight of the liquid. The reservoir can include a constricted portion providing a venturi effect.

Apparatus and methods are provided for brewing a beverage from precursor particulates. The apparatus comprises a liquid delivery system for delivering liquid into a brewing basket. The liquid delivery system comprises a showerhead disposed above at least a portion of the brewing basket. The showerhead has a plurality of outlet openings through which liquid flows outward from the showerhead into the brew basket. At least two of the outlet openings are oriented to direct the flow of liquid out of the showerhead at least in part transversely of the brew basket.

According to the present disclosure, when drip coffee is extracted, it may learn drip coffee recipe information of a barista to be imitated and extract the drip coffee based on the learned reference acidity and reference concentration. The extracted drip coffee may be compared with the learned reference acidity and the reference concentration and evaluated, and when the acidity and concentration of the drip coffee are matched with the reference acidity and the reference concentration, the drip coffee having the same acidity and concentration as the drip coffee may be extracted. Alternatively, when the acidity and concentration of the drip coffee are not matched with the reference acidity and the reference concentration, drip coffee having the same or/and similar acidity and concentration as or/and to the reference acidity and the reference concentration may be extracted by changing extraction conditions of the drip coffee through reinforcement learning.

Disclosed herein are a drip coffee machine and a liquid discharge device used therefor including: a liquid providing module having a discharge pipe discharging liquid to coffee beans; a rotation module having an actuator generating rotational force, a driven gear rotated by receiving the rotational force, and a base plate rotated by being connected to the driven gear, the base plate being configured to move the discharge pipe along a rotation trajectory when rotated; and a translation module including a translation drive unit having an elastic pull member elastically deflecting the discharge pipe along a translation trajectory, an adjustment cam installed to be rotatable with respect to the base plate to adjust the position of the discharge pipe elastically deflected within the translation trajectory by the elastic pull member in the one direction or the other direction opposite to the one direction and having its outer circumferential surface in contact with the discharge pipe, and an intermediate unit transmitting the rotational force generated by the actuator to the adjustment cam , wherein the discharge pipe discharges the liquid while being moved along a discharge trajectory in which the rotation trajectory and the translation trajectory are combined with each other.

A pour over coffee maker includes a machine body, a water cup and a clamping device, wherein the water cup is arranged on the machine body, and the clamping device is equidistantly arranged on a periphery of a bottom of the machine body. When using the pour over coffee maker, the clamping device is used to clamp a periphery of a coffee cup, and then the hot water is injected into the water cup, so that the hot water flows into a water injection pipe of the machine body through the water cup to enable a spiral water injection device connected to the water injection pipe to performs a spiral water injection operation, and after the hot water is injected for a period of time, the water injection pipe is pressed by an abutting element provided in the machine body to stop the water injection, thereby achieving the function of blooming, and since the size of the pour over coffee maker is only similar in size to that of a filter cup, so it can be carried around and has the function of brewing coffee at any time.
