Abstract
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.
Claims24
A coffee maker, comprising:
- a dripper that receives coffee powder and includes an extraction hole formed on a lower surface for extracting coffee from the coffee powder;
- a dripper valve module that operates in an open state to open the extraction hole or a closed state to close the extraction hole;
- and
- a water outlet module that performs an operation of supplying water to the coffee powder,
- wherein the water outlet module performs a water supply operation in each of first and second water supply sections that are sequential,
- in the first water supply section, the dripper valve module operates in the closed state, and in the second water supply section, the dripper valve module operates in the open state.

A coffee maker, comprising:
- a dripper that receives coffee powder and includes an extraction hole formed on a lower surface for extracting coffee from the coffee powder;
- a dripper valve module that operates in an open state to open the extraction hole or a closed state to close the extraction hole;
- and
- a water outlet module that performs an operation of supplying water to the coffee powder,
- wherein an opening degree of the extraction hole corresponds to a level of the open state of the dripper valve module,
- the level of the open state of the dripper valve module is set based on a particle size of the coffee powder.
A control method of a coffee maker comprising a processor, comprising:
- controlling a dripper valve module to close an extraction hole formed in a lower surface of a dripper in which coffee powder is received;
- controlling a water outlet module to supply water to the coffee powder in a first water supply section;
- controlling the dripper valve module to open the extraction hole;
- controlling the water outlet module to supply the water to the coffee powder in a second water supply section;
- and
- controlling the dripper valve module to close the extraction hole.
