  • No-bean detection for coffee bean grinder
    Patent number: 9675211
    Abstract: A method for detecting a state of a coffee bean grinder includes providing a supply voltage to a motor of a grinding apparatus, and monitoring with a motor stall detection sensor at least one operating parameter of the motor. The method further includes determining whether a motor stall has been detected based on monitoring the at least one operating parameter. The method also includes measuring using a weight sensor a weight of coffee grounds that have been ground by the grinding apparatus, and determining that no beans are present in a hopper that feeds coffee beans to the grinding apparatus when no motor stall has been detected and no change in weight has been detected at the weight sensor for a predetermined amount of time. A coffee bean grinder is also disclosed.
