Abstract: The preset disclosure relates to a dishwasher. The dishwasher includes: a tub defining a washing space; a sump disposed below the tub and configured to store wash water therein; a pump configured to supply the wash water stored in the sump to the tub; and a spray arm configured to supply wash water flowing from the pump to the washing space. The spray arm includes: a spray blade configured to spray wash water into the washing space; a bubble generator having therein a bubble generation flow path of a venturi tube shape and configured to supply wash water containing a microbubble to the washing space; and a hub configured to supply wash water discharged from the pump to the spray blade or the bubble generator. The spray arm sprays wash water through the spray blade while simultaneously generating a microbubble through the bubble generator.

Abstract: A spray arm, a water pumping mechanism and a cleaning machine thereof are disclosed in the present invention. The spray arm comprises a body (1;1′) and a top plate (2;2′). An air collection chamber (20;20′) is defined between the top plate (2;2′) and the top surface (1a; 1a′) of the body (1;1′), a plurality of water spray holes (13) is arranged in the air collection chamber (20;20′), the top plate (2;2′) has a plurality of spray openings (21) each corresponding to one water spray hole (13), and a gap (100) is formed between a top end of each water spray hole (13) and a bottom end of the corresponding spray opening (21). According to the Venturi effect, the air in the air collection chamber can be sucked into the spout through the gap when the water flow passes through the water spray hole and is jetted out through the spray opening, such that bubbles are entrained in the jet flow; the bubbles are broken on surfaces of dishes or fruits and vegetables, which can improve dirt stripping force, and improve the washing effect.

Abstract: A dishwasher may utilize a multi-level dishwasher rack that in some instances may be reconfigurable into different configurations to optimize the rack for different types and/or combinations of utensils. A movable divider may be used in some instances to selectively expose a deep portion of a rack, and a drawer may be used in some instances to provide access utensils stored underneath a divider. A movable portion of a bottom of a rack may also be used in some instances to provide different support surfaces in the rack at different elevations. A tubular spray element or another rotatable spray tube may also be positioned relative to a multi-level dishwasher rack in some instances to facilitate concentrated washing of different facing surfaces of different utensils stored in the rack.
