    Abstract: A cleaner head for a vacuum cleaner has a rotating brush bar driven by an air-cooled motor, which is mounted inside the cleaner head with at least a section of the motor being located inside the brush bar. To cool the motor in use, an external casing of the motor is provided a plurality of air-cooling holes comprising at least one air intake and at least one air exhaust. These cooling holes are connected—intake to exhaust—to form one or more air-cooling paths through the inside of the motor. Each air intake is connected to an upstream clean air inlet by a stationary—not rotating—intake duct, and each air exhaust is similarly connected to a downstream clean air outlet by a stationary—not rotating—exhaust duct. This avoids the problems associated with using the rotating brush bar itself as a duct for carrying cooling air to the motor.

    Abstract: An agitation apparatus which is suitable for use in a cleaning head of a vacuum cleaner includes first and second flow paths. Each of these flow paths has a resonant cavity and an inlet/outlet port which joins the cavity to a space within the cleaning head. A generator, such as a loudspeaker with a diaphragm, generates an alternating pressure wave between the ports. Pressure waves are emitted from one of the ports in an anti-phase relationship with the pressure waves from the other of the ports, thus reducing operating noise. Due to both sides of the generator or diaphragm being exposed to an equal static pressure, the generator operates more reliably. A plurality of these arrangements can be provided across the cleaning head, and a part of the agitation apparatus, such as the driver, can be mounted on the main body of the vacuum cleaner.

  • Patent number: 7251858
    Abstract: A floor care apparatus has a nozzle assembly housing an agitator. A motor couples to the agitator to drive it at two or more speeds and constant suction power. A user indicates their mode-of-operation preference by positioning a switch. An agitator motor control circuit, responsive to the switch, effectuates motor control by supplying either a fixed duty cycle signal or a substantially constant voltage signal. The fixed duty cycle signal includes a waveform with a substantially constant voltage value that is on for a first or first and second of four quarters of the waveform period. Thereafter, it repeats for additional periods. The switch preferably embodies a resistor network and a fixed current source that creates a voltage input to an A/D converter that falls within a specified range. Other apparatus embodiments contemplate multiple agitators with one or more agitator motors. A suction fan motor, separate from the agitator motor(s), may also exist.

  • Patent number: 7246408
    Abstract: A cleaning tool for a vacuum cleaning device has a housing having a bottom plate with a working slot. A rotatingly driven working tool is rotatably supported in the housing and passes through the working slot to act on a surface to be cleaned. A motor is arranged in the housing and has a motor shaft. A gear system is connected between the motor and the working tool, wherein the gear system has a driving wheel driven by the motor shaft and a driven wheel fixedly connected to the working tool. The driving wheel and the driven wheel are V-belt pulleys and have a peripheral groove, respectively. The gear system further has a V-gear positioned between the driving wheel and the driven wheel, wherein the V-gear has an outer periphery that engages the peripheral grooves for establishing a driving connection between the driving wheel and the driven wheel.

  • Patent number: 7237298
    Abstract: Several methods of controlling a vacuum cleaner (10) using various types of sensors (94, 96, 97, 98) are provided. One method is based on a differential pressure between a suction airflow path and ambient air and includes: detecting the differential pressure, comparing the detected differential pressure to a predetermined threshold, and, when the detected differential pressure is less than the predetermined threshold, initiating a predetermined control procedure. A status indicator (164) is updated based on the detected differential pressure. Another method is based on a level of electrical current flowing through a brush motor (100). Still another method is based on a type or condition of the floor being traversed. Yet another method is based on a distance to a surface of a floor over which the vacuum cleaner is advancing. In another aspect of the invention, a vacuum cleaner is provided.
