  • CHEMISTRY DISPENSING SYSTEM FOR A LAUNDRY APPLIANCE HAVING REMOVABLE CHEMISTRY CARTRIDGES
    Publication number: 20250059696
    Abstract: A cartridge for a laundry appliance includes an outer housing having an interior chamber therein. The outer housing includes a primary axis and a secondary axis that is perpendicular to the primary axis. A pump is contained within the outer housing that selectively delivers a laundry chemistry from the interior chamber to a dispensing outlet of the outer housing. The dispensing outlet is defined within a contoured edge of the outer housing and orients the dispensing outlet at an oblique angle with respect to the primary and secondary axes. A rotational drive is operated by an external actuator. The rotational drive is positioned within the outer housing and in operable communication with the pump. The rotational drive aligns with a drive aperture defined within a wall of the outer housing for receiving the external actuator.
