A recently granted patent (Publication Number: US11882975B2) discloses a novel dishwasher design featuring a multi-level rack with deep and shallow portions to accommodate different utensil sizes. The rack includes a unique rotatable spray tube positioned to direct fluid upwardly into the rack to clean utensils efficiently. The spray tube can rotate to spray downwardly-facing surfaces of utensils in the shallow portion and laterally-facing surfaces of utensils in the deep portion, enhancing the cleaning process. Additionally, the patent describes variations in the design, such as multiple rotatable spray tubes and different configurations for the movable portion of the rack, allowing for versatility in utensil placement and cleaning.

Furthermore, the patent details the movable portion of the rack, which can be adjusted to support utensils at different elevations, creating a deep portion for taller utensils and a shallow portion for smaller items. The movable portion can slide or pivot between configurations, providing flexibility in organizing utensils for washing. The design also includes hinged members that can rotate or be removed, offering further customization options for users. By allowing for linear or vertical movement of the movable portion, the dishwasher design aims to optimize space utilization and cleaning efficiency, catering to a variety of utensil sizes and shapes. Overall, the patented dishwasher design presents innovative features to enhance the washing process and adapt to different user needs.
