Abstract
Provided are a coffee extraction device and a coffee extraction method, which are capable of extracting coffee from a coffee capsule (capsule coffee) and the like. The coffee extraction device can comprise: a coffee extraction unit on which a coffee capsule is to be mounted; a pump for pressurizing water and supplying the same to the coffee extraction unit; a flow rate sensor for measuring the flow rate of water to be supplied to the coffee extraction unit; and a control unit for controlling the operation of the pump on the basis of the flow rate to be sensed at the flow rate sensor.
Claims21
A coffee extraction device comprising:
- a coffee extraction unit in which a coffee capsule is mounted;
- a pump pressurizing water and supplying the water to the coffee extraction unit;
- a flow rate sensor measuring a flow rate of the water supplied to the coffee extraction unit;
- and
- a control unit controlling driving of the pump, based on the flow rate sensed by the flow rate sensor.
A coffee extraction method comprising:
- a pump driving process of driving a pump to supply high-pressure water to a coffee capsule;
- and
- a re-extraction process of stopping driving of the pump and then performing redriving of the pump when a flow rate of water supplied to the coffee capsule is lower than a preset flow rate.
A coffee extraction method comprising:
- a pump driving process of driving a pump to supply high-pressure water to a coffee capsule;
- and
- a re-extraction process of stopping driving of the pump and then performing redriving of the pump when a water amount supplied to the coffee capsule does not reach a preset water amount within a preset time.
