NO-BEAN DETECTION FOR COFFEE BEAN GRINDER |
| 摘要 |
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. |

1. A method for detecting a state of a coffee bean grinder, the method comprising:
providing a supply voltage to a motor of a grinding apparatus; monitoring with a motor stall detection sensor at least one operating parameter of the motor; determining whether a motor stall has been detected based on monitoring with the motor stall detection sensor the at least one operating parameter of the motor; measuring using a weight sensor a weight of coffee grounds that have been ground by the grinding apparatus; 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. |
