Abstract
A method of monitoring a washing drum in a washing machine for impermissible or atypical movement during a first phase of a washing program as may result, for instance, from the presence of a child or animal in the drum, and of aborting the washing program upon detection of such impermissible movement.
Claims6
A method of operating a washing machine comprising a housing, a loading door, a washing fluid tub suspended within the housing for oscillating movements, a washing drum disposed within the washing fluid tub, a motor configured to induce rotation movement to the washing drum, and a detector configured to detect rotary movement of the drum, the method comprising:
- monitoring the rotary movement of the drum with the detector during a first phase of the washing program while the motor is inactive;
- and
- preventing continuation of the washing program in response to a detection of rotary movement of the drum that is not imparted by the motor during the first phase of the washing program.
