Method for brewing a beverage

摘要

One variation of an apparatus for brewing a beverage includes: a reservoir containing fluid; a boiler including a heating element and a fluid pickup, a portion of the boiler arranged vertically below the reservoir; a brew chamber, a portion of the brew chamber arranged vertically above the boiler; a first contactless valve operable in a first mode and in a second mode, the first contactless valve open in the first mode to communicate fluid from the reservoir into the boiler and closed in the second mode; a second contactless valve operable in the first mode and in the second mode, the second contactless valve open in the first mode to vent gas from the boiler and closed in the second mode; and an air pump configured to displace air into the boiler in the second mode to displace fluid from the boiler, via the fluid pickup, into the brew chamber.

主权项

1. A method for brewing a beverage at a brewing apparatus, the method comprising:
retrieving a brew recipe for a brew cycle based on a selection for the brew recipe; calculating a pump duration based on a target fluid volume specified in the brew recipe; opening a first valve arranged between a reservoir and a boiler to dispense fluid from the reservoir into the boiler; closing the first valve in response to receipt of an output from a fluid level sensor within the boiler indicating achievement of a target fluid level within the boiler, the target fluid level specified in the brew recipe; actuating a first heating element thermally coupled to the boiler to heat fluid within the boiler; closing a second valve, the second valve coupled to an exhaust port of the boiler by a first fluid conduit; pumping gas into the boiler for the pump duration to dispense heated fluid from the boiler, through a second fluid conduit, into a brew chamber in response to receipt of an output from a temperature sensor thermally coupled to the boiler indicating achievement of a target brew temperature within the boiler, the target brew temperature specified in the brew recipe; and actuating a second heating element thermally coupled to the brew chamber to maintain fluid within the brew chamber at the target brew temperature.
