Abstract: Methods for cleaning at least one soiled substrate in a rotatably mounted cylindrical drum of a cleaning apparatus with a multiplicity of solid particles are provided. One method includes the steps of: agitating the at least one soiled substrate in the drum with wash liquor and the multiplicity of solid particles for a first cleaning cycle wherein the wash liquor includes at least one cleaning agent; draining the wash liquor from the cleaning apparatus; and introducing an aqueous non-detergent medium into the cleaning apparatus and agitating the at least one soiled substrate with the multiplicity of solid particles in the drum for a second cleaning cycle. Another method includes rotating the drum such that the at least one soiled substrate moves about a generally circular path and introducing the multiplicity of solid particles into the drum through an annulus defined by the generally circular path as the drum rotates.

Abstract: A lower rack assembly for a dishwasher appliance includes a lower rack configured for receipt of articles for washing, and a lift assembly connected to the lower rack. The lift assembly includes a first arm extending between a first end and a second end, the first end of the first arm pivotally coupled to the lower rack, and a first bracket defining a first slot, the second end of the first arm movably coupled to the first slot. Movement of the lower rack along the vertical direction causes movement of the second end of the first arm relative to the first slot along the transverse direction and pivotal rotation of the first end of the first arm.

Abstract: Apparatus for filter cleaning including a filter element surface (12) to be cleaned, and a cleaning head (10), characterized by a controller (16) operative to move the cleaning head (10) with respect to the filter element surface (12) in a spiral scanning trajectory in such a way that a relative path of the cleaning head (10) with respect to the filter element surface (12) results in a trajectory that fully, or partially covers the filter element surface (12) and is produced by moving the filter element surface (12) in any combination of the following motions: a) one or more circular or semi-circular motions, b) one or more linear motions; while moving the cleaning head (10) in any combination of the following motions: c) one or more circular or semi-circular motions, d) one or more linear motions.

Abstract: Disclosed is a washing machine including an inner tub in which fabrics are accommodated, a fixing hub installed to the inner tub, a rotating shaft configured to penetrate the inner tub and the fixing hub, a sun gear installed to the rotating shaft and having a lower gear portion and an upper pulsator coupling portion, an inner pulsator coupled to the pulsator coupling portion, a plurality of planetary gears engaged with the gear portion and rotatably arranged on the fixing hub, a ring gear having an inner circumferential surface engaged with the planetary gears, a gear box coupled to the ring gear, and an outer pulsator coupled to the gear box, the outer pulsator being larger than the inner pulsator. As the inner pulsator and outer pulsator are rotated at different rates of rotation, complex 3D water stream may be created in the inner tub, resulting in enhanced washing ability.
