Abstract: A method for determining a target rotational speed below an application rotational speed of a washing drum of a laundry treatment device having a drive and a vibrating system, wherein a dependence of a mechanical effect on items to be washed located in the washing drum on the respective nominal speed of the washing drum is used to ascertain the target rotational speed at which the mechanical effect is at the greatest. The mechanical effect at a respective target rotational speed is ascertained by measuring vibrating system movements of the vibrating system which exhibit greater frequency than the respective target rotational speed. The rotational speed at which the maximum vibrating system movement was measured is selected for carrying out the washing care procedure. The advantage of such a method is that the washing mechanics can be increased, thus improving the cleaning efficiency.

Abstract: A laundry treatment machine and a washing method therefor are provided. The laundry treatment machine may discharge fluid by driving a drainage device, while rotating a drum during a time period between a plurality of rinsing operations. The rotation speed of the drum may be controlled to be lower than a reference speed, which is the rotation speed of the drum when laundry is not uniformly distributed in the drum, and thus, eccentricity of the laundry is high.

Abstract: A bearing assembly is for a washing machine, the washing machine including a tub and a drum rotatable about a central axis. The bearing assembly comprises two bearings spaced axially apart along the central axis, a spacer disposed generally between the two bearings, and a polymeric housing. The housing includes a box-type frame molded to the bearings and to the spacer and configured to provide stiffness to the bearing assembly.

Abstract: A hand carried, manually operated apparatus for cleaning flooring, carpet, upholstery, and the like includes a cleansing fluid chamber, a waste fluid chamber, a pump and an applicator. A first fluid passageway connects the pump and cleansing fluid chamber, a second passageway connects the cleansing fluid chamber and applicator, a third passageway connects the applicator and waste fluid chamber, and a fourth passageway connects the waste fluid chamber and pump. A first one-way valve permits flow from the pump to the cleansing fluid chamber but inhibits reverse flow; and a second one-way valve permits flow from the applicator to the waste fluid chamber but inhibits reverse flow. Air is transferred through the pump from the waste fluid chamber to the cleansing fluid chamber as cleansing fluid is transferred to the applicator from the cleansing fluid chamber and waste fluid is transferred from the applicator to the waste fluid chamber.

Abstract: A dishwasher includes a spray arm assembly positioned in the wash chamber of the dishwasher's tub. The spray arm assembly includes a corner arm that is driven by a gear train. The transfer gear assembly of the gear train is operable to decouple the gear train from its input when rotation of the corner arm is obstructed.

Abstract: An ultrasonic cleaning apparatus including: a cleaning tank for storing a cleaning liquid; an object-to-be-processed holder for insertion into the cleaning tank, the holder holding an object to be processed and immersing the object into the cleaning liquid; a vibrator disposed on a bottom part of the cleaning tank; and an ultrasonic oscillator configured to make the vibrator ultrasonically vibrate. In the cleaning tank, a lateral holding member configured to hold the object is disposed. The holder is configured to be laterally moved by a driving apparatus. The control device is configured to control the driving apparatus such that the holder is laterally moved after the object has been held by the lateral holding member, and the control device is configured to control the ultrasonic oscillator such that the vibrator is made to ultrasonically vibrate so that the ultrasonic vibration from the vibrator is propagated to the object.
