A cold brew coffee maker includes a water drip supply unit for dripping drops of water through a water dispensing port; a coffee container configured to steep the ground coffee in the coffee container to produce coffee extract using the water dripped from the water drip supply unit; a collecting container disposed below the coffee container and configured to collect the drops of the coffee extract dripping through a coffee extract dispensing port; and a collection guide member configured to guide the drops of the coffee extract to flow downward along the inner wall surface of the collecting container to fill the coffee extract collecting container. The water drip supply unit further includes a control unit configured to control an electric valve based on the water drop detection signal from a sensor unit so that the water drops can drip from the water dispensing port at a preset supply rate.

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.

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 coffee maker and a control method therefor are disclosed. The disclosed coffee maker controls a dripper valve module to be closed in a first water supply section corresponding to a pre-wetting process so as to close an extraction hole, and controls the dripper valve module to be opened in a second water supply section corresponding to a coffee extraction process so as to open the extraction hole. Accordingly, a coffee drip process similar to a hand drip operation can be implemented.

The present invention relates to a drip coffee machine. The drip coffee machine according to an embodiment of the present invention comprises: a case; a hopper for accommodating coffee beans; and a grinder for receiving and grinding the coffee beans, wherein the grinder is coupled to the case in a detachable manner, and the grinder includes: a grinder body including a rotating burr; and a grinder driving part, which is connected to the grinder body and provides rotating force to the burr.

The present invention relates to a drip coffee machine, comprising: a dripper for accommodating coffee powder and extracting liquid coffee; a water outlet unit having an water outlet hole through which water is dropped onto the coffee powder; a driving unit for changing the position of the water outlet hole; and a sensor unit for detecting the position of the driving unit.

A coffee maker is disclosed. The disclosed coffee maker has a dripper cap provided inside an extraction hole of a dripper and allows the dripper cap to move up and down linearly by means of screw rotation. Therefore, the operation of opening/closing the extraction hole can be simply implemented.

A beverage maker including a reservoir, an intermediate chamber, a beverage substance retaining container, a heating element associated with the reservoir and a temperature responsive valve assembly between the reservoir and intermediate chamber for controlling the flow of heated water from the reservoir. The beverage maker includes a sensor device coupled to the reservoir, spaced from the heating element, to detect a condition such as a temperature change, temperature, temperature range, or presence of absence of water within the reservoir to cease power to the heating element upon detecting the condition. The intermediate chamber is sized and dimensioned to accommodate a predetermined range of volumes of water flowing from the reservoir through the intermediate chamber. A spray head is provided on the intermediate chamber communicating with the volume of water retained therein to distribute the water over beverage making substance retained in the beverage substance retaining container.

An automatic drip coffee machine includes a drip part, a hot water supply unit, a pedestal, a load cell, and a controlling part. The drip part pours water into a dripper containing coffee beans in a predetermined amount to brew coffee. The hot water supply unit provides the heated water to the drip part. The pedestal supports a drip container for supporting the dripper and storing the extracted coffee by the dripper. The load cell is disposed in the pedestal and measures weights of the dripper and the drip container. The controlling part calculates an error value between a predetermined water injection amount of the drip part and an amount of water actually poured from the drip part into the dripper using weights of the dripper and the drip container measured by the load cell and readjusts the water injection amount of the drip part based on the error value.
