Abstract
A coffee brewer and hot water dispenser, which includes a brew water tank (30), with water heated to a pre-determined temperature by a pre-heater (38). A boiler (50) boils the pre-heated water into a spray head (56) and into a ground coffee containing cone (114). A separate hot water tank (70) is heated by a heater (72), and a solenoid valve (74) dispenses hot water into a container. Fill, water level dispensing and process control use a solid state electronic controller (140) interconnected to an indicating control panel (112). The improvement permits larger capacity by the use of a bypass hot water cycle adding a predetermined volume of water to the container and supplementing the control by expanding its capabilities using multiple sequencing of the brew cycle for increasing the volume of brewed coffee.
