  • Patent number: 7712183
    Abstract: An electric vacuum cleaner (1) of the invention is adapted for wipe off cleaning using a sheet wound about a rotary brush (25) incorporated in a suction device (10). In order to wind a sheet (50) around a periphery of the rotary brush (25), a brush motor (44) rotates the rotary brush (25) in a predetermined direction at a predetermined rotational speed. At the same time, suction force of an electric blower fan (42) is set to the lowest level. This achieves the following advantage in a case where a wet sheet is used as the sheet (50). During sheet winding, water and alcohol released from the wet sheet (50) can be prevented from being scattered on a surface (100) to be cleaned. Further, the released water and alcohol do not adversely affect the electric blower fan (42).

    Abstract: An obstacle-sensing system for carriers, particularly autonomous carriers such as robot vacuum cleaners, enables the carriers to disengage themselves from any obstacle or obstruction with which they come into physical contact and proceed past the obstacle or obstruction. The obstacle-sensing system is established by constructing a carrier to have front and rear sections which, normally, are in a neutral relationship with respect to one another but which move relative to one another when the front section physically engages an obstacle or obstruction. The relative movement activates a guidance and control system that maneuvers the carrier around the obstacle or obstruction.

  • Publication number: 20090100637
    Abstract: The present invention discloses a vacuum cleaner which can remove substances from the bottom by a rotary force of a brush and a vacuum pressure operated on a suction head by rotatably installing the brush on the suction head. The vacuum cleaner consults a user's convenience by preferentially sucking thin and long substances such as hairs or furs of a pet dog not to be wound around the brush. The vacuum cleaner includes a suction head being installed at a front end of a suction path for sucking substances by a vacuum pressure generated by a suction motor, and having a suction hole for sucking the substances on its bottom, a brush installed on the suction hole of the suction head, and rotated to contact the bottom, and a hair tunnel formed on the suction head not to interfere with the brush, for preferentially sucking thin and long substances from the bottom.

  • Patent number: 7516509
    Abstract: The present application relates to a pneumatic device for cleaning ventilation ducts, which includes a guiding air hammer, a turning conduit, an air-supply pipe and a slewing mechanism for the conduit. The guiding air hammer has a hollow spherical or hemispherical shape and is connected to the turning conduit. A cleaning fumarole and a guiding fumarole are provided on the rear arc wall of the guiding air hammer. When in operation, the air-supply pipe stretching means retracts and stretches the air-supply pipe, which enables the guiding air hammer to clean out the dust on the inner walls and in the corners of a ventilation duct without the need of an operator entering the ventilation duct. The air-supply pipe stretching means may be controlled by manual operation or program composition. The device may be used for cleaning ventilation ducts with a polygonal section.

  • Publication number: 20090083934
    Abstract: A sweeping broom apparatus for use with a vehicle comprises a main body with a debris receiving inlet, and a broom shroud with an open bottom. Airflow obstructing flaps are disposed around the bottom edge of the broom shroud. A forwardly facing debris outlet in the broom shroud permits the directed egress of debris therefrom as a forwardly propelled stream of debris. A main sweeping broom is mounted within the broom shroud for propelling debris forwardly, thereby creating a stream of debris propelled forwardly through the forwardly facing debris outlet. An air blast nozzle is connected in fluid communication to a source of compressed air for receiving compressed air therefrom. There is a nozzle mount for mounting the air blast nozzle for movement between a lower position whereat the air blast nozzle is disposed adjacent the surface being cleaned and to emit air in a forward and downward direction to impact on the surface being cleaned, and a raised impact-absorbing position.
