More Information
Summary:A coffee brewing device (100) is provided having a conduit (108) extending from a one-way valve (106) to a delivery outlet (109). Water is supplied via the delivery outlet into a reservoir (102) for holding coffee grounds. Water in a heatable section (110) of the pipe is heated to generate water vapor bubbles. The one-way valve is arranged to limit backflow in a direction away from the delivery outlet such that heated water comprising water vapor bubbles is conveyed in the conduit from the heatable section to the delivery outlet. A sensor (120) senses blisters in the water in the conduit between the heatable section and the delivery outlet. It has been found that the sensor helps to control how much heated water is delivered to the reservoir in a reliable, compact and relatively low-cost manner, and correspondingly to control the amount of brewed coffee produced. A method of operating such a coffee brewing device and an associated computer program are also provided.
