  • Patent number: 8636174
    Abstract: An on-demand hot water dispenser (10, 90) with a source of hotter water (30) at a preselected relatively elevated temperature (36, 40, 42) and a source of cooler water at a relatively non-elevated temperature compared to the hotter water (17, 52) has an outlet dispense valve (18, 92) connected with both the hotter water source and the cooler water source through a common mixing chamber (74) to selectively vary the temperature of the mixed water being dispensed. The cooler water source (17, 52) is connected to the outlet dispense valve (18, 92) through an electrically controlled proportional valve (72) with a variable flow rate that is controlled during dispensing and mixing in accordance with a comparison between a selected one of a plurality preselected temperatures stored in a controller (34) and a sensed temperature (60, 62) of the mixed water in the mixing chamber (74) to maintain the mixed temperature of the water being dispensed at a preselected temperature on a real-time basis.

  • Patent number: 5662955
    Abstract: A coffee grinder which has several different automatic grinding capacities is connected to a coffee brewer which has several different automatic brewing capacities by a control that inhibits brewing of all but the corresponding brew capacity following grinding of a quantity of coffee. The grinder is also inhibited from grinding any more coffee until the appropriate brew cycle of the coffee brewer is started. Once the corresponding brewing cycle is selected, the coffee grinder is reset and any grinding capacity may be selected. A calibration mode for the coffee grinder and the coffee brewer is provided wherein the duration of the grinding cycle or brewing cycle, respectively, is set by manually initiating the cycle and then halting of the cycle when the appropriate capacity is reached. The duration of the cycle is then set for subsequent automatic operation.
