Device for metering coffee brewing

摘要

A device for brewing coffee. The device includes a microprocessor, a user actuated controller for interfacing with the microprocessor, a tank for retaining water and a heating element for selectively heating the water. The device further includes a brewing basket for receipt of water from the tank, and a cone valve located in a dispersing end of the brewing basket. The microprocessor dictates a measured quantity of water to be delivered to the brewing basket in conjunction with a measured amount of ground coffee for brewing. In a preferred embodiment, a multichannel valve is employed together with a suitable pump for controlling fluid flow as dictated by the microprocessor.

主权项

1. A device for brewing coffee comprising a microprocessor, a user actuated control device for interfacing with said microprocessor, a tank for retaining water, a heating element for selectively heating said water, a brewing basket for receipt of water from said tank and ground coffee, a weighing mechanism and a cone valve assembly at an output of said brewing basket for controllably dispensing brewed coffee from said brewing basket, said microprocessor being interfaced with a controller for a multichannel valve assembly such that upon actuation of said user activated controller, a quantity of coffee to be brewed is introduced to said brewing basket and weighed by said weighing mechanism and a control signal from said weighing station supplied to said microprocessor, said microprocessor generating a control signal for actuating a pump and selecting a first orientation for said multichannel valve assembly for feeding a measured quantity of heated water to said brewing chamber based upon said quantity of coffee and further generating a control signal to said valve assembly and pump to terminate the feeding of water to said brewing basket after said measured quantity of heated water had been introduced thereto and further generating a control signal to said cone valve for selectively opening said cone valve assembly for dispensing brewed coffee from said brewing basket.
