  • Robot cleaner
    Patent number: 7474941
    Abstract: A robot cleaner is provided. The robot cleaner comprises a bumper to buffer a shock caused by a sudden collision with an unexpected obstacle and an unexpected obstacle detecting means and a controller to change a running direction of the robot cleaner to avoid the obstacle. Accordingly, when an unexpected obstacle appears in front of the cleaner and the cleaner collides with the obstacle, the bumper buffers and absorbs the shock, thereby preventing damage to a cleaner body and inner parts. Also, the robot cleaner can avoid the obstacle and, thus, complete a cleaning operation without stopping the cleaning operation.

  • Robot cleaner coordinates compensation method and a robot cleaner system using the same
    Patent number: 7438766
    Abstract: A coordinates compensation method of a robot cleaner using an angle sensor compensates coordinates of the robot cleaner with reference to absolute coordinates of a recharging station, so as to improve robot cleaner's path following. The robot cleaner is in a standby mode at the recharging station, and moves to an operation area to perform a given job. The robot cleaner stops the given job upon determining an accumulative angle exceeding a predetermined level, and returns to the recharging station. Current coordinates of the robot cleaner are aligned with reference coordinates of the recharging station, and the robot cleaner moves to a previous spot where it was before it returns to the recharging station, and resumes the work from where it stopped.

  • Cyclone dust collecting apparatus
    Patent number: 7416575
    Abstract: A cyclone dust collecting apparatus has a cyclone body having an air inlet for drawing in, contaminant-laden air and an air outlet connected with a vacuum suction source. The vacuum provided by the vacuum source draws air from the air outlet, which passes through the cyclone body from the air inlet. As the air flows through the cyclone body, it forms a whirling stream in the cyclone body. The whirling stream creates a centrifugal force on particles that are suspended in the air, which, because of their greater mass, causes them to become separated from air that is drawn out of the whirling stream and into the air outlet by the vacuum source. The air outlet is provided with a passage guide member arranged in the air outlet that reduces the speed of air discharged via the air outlet and also for guiding a flow streamline.
