Abstract: A washing machine having a sub-pulsator, the washing machine including a pulsator rotating in the left/right directions by a driving source during the washing process and guide duct mounted in a wash/spin-dry tub for guiding the washing water agitated by left/right rotations of the pulsator to the upper side of the wash/spin-dry tub, wherein the washing machine comprises:a hydraulic turbine disposed in the guide duct; anda sub-pulsator arranged in the wash/spin-dry tub to mesh with the hydraulic turbine, such that a side water current is formed at an intermediate section of the wash/spin-dry tub without recourse to input of separately added power to thereby improve the washing performance.

Abstract: A clothes washing machine includes a spin-dry tub and an oscillatory agitator disposed at the bottom of the tub. The agitator includes a centrally located vertical hole in which an axial fan is mounted. A drive mechanism oscillates the axial fan relative to the agitator about a vertical axis to generate an upward water jet that disperses the laundry in a manner preventing entwinement and entanglement thereof. The driving mechanism comprises a roller mounted on an underside of the agitator. The roller engages the bottom of the tub and is oscillated by frictional contact therewith during oscillation of the agitator. Oscillation of the roller is transmitted to the axial fan by a flexible shaft.

Abstract: The present invention relates to a vibroisolating apparatus for a vacuum cleaner adapted to absorb and inhibit the vibrations generated in a suction motor from being transmitted to a body of the vacuum cleaner to thereby reduce the noise resulting from the vibration to a minimum, and at the same time, to improve the ease of assembling and to decrease manufacturing cost by way of a simplified construction. The vibration generated in the suction motor during operations is absorbed and inhibited at a front side of the motor by a vibroisolating ring which is tightly disposed between a front motor case and the suction motor. The vibration is also absorbed and inhibited at a rear side of the motor by the rear surface packing which is disposed between a rear motor case and the motor. The apparatus thereby reduces generation of noise resulting from the vibration of the suction motor to a minimum and provides for relatively silent operation of the vacuum cleaner.

Abstract: A suction head for a vacuum cleaner includes a rag roll device which is wetted to perform a wet wiping action across the floor. The rag roll device is mounted for rotation about a horizontal axis. A rotation regulating mechanism, comprised of a pawl device and ratchet teeth, is provided which prevents the rag roll device from rotating when the suction head is moved forwardly, while permitting the rag roll device to rotate by a predetermined angle when the suction head is moved rearwardly. This enables different portions of the rag roll device to assume a floor-contacting position.
