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.
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.
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 a source of ground coffee wherein upon actuation of said control device, said microprocessor dictating delivery of heated water from said tank and said ground coffee to said brewing basket and further comprising a weighing station, the output of which is fed to said microprocessor and further comprising a multichannel valve and actuator therefore, said microprocessor controlling said actuator for changing fluid flow through said multichannel valve and further comprising a pump and actuator therefore, said microprocessor controlling said actuator for causing water to be selectively passed through said multichannel valve and air to be introduced into said brewing basket for mixing.
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, a cone valve assembly located at a dispensing end of said brewing basket, a device for indicating to said microprocessor the quantity of heated water delivered to said brewing basket and further comprising a hopper for retaining a supply of coffee beans and a grinder positioned to receive coffee beans to be ground from said hopper and further comprising an Archimedes screw for transferring ground coffee from said grinder to said brewing basket.
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, a cone valve assembly located at a dispensing end of said brewing basket, a device for indicating to said microprocessor the quantity of heated water delivered to said brewing basket and further comprising a weighing station including an electronic balance located proximate said brewing basket to weigh the contents thereof.
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, a cone valve assembly located at a dispensing end of said brewing basket, a device for indicating to said microprocessor the quantity of heated water delivered to said brewing basket and a multichannel valve assembly, said multichannel valve assembly comprising a motor selectively activated by said microprocessor, and a plurality of channels for selectively directing fluids therethrough.
