Abstract: An additive dispensing system and method for dispensing wash additive from an additive reservoir of a washing machine appliance is provided. The additive dispensing system includes a tank level sensor and a Venturi pump for drawing wash additive from the additive reservoir. The method includes measuring a level of wash additive in the additive reservoir using the tank level sensor and/or the viscosity of the wash additive, determining an additive dispense rate based at least in part on the level of wash additive and/or the viscosity of the wash additive, and selectively dispensing the flow of water through the Venturi pump based at least in part on the additive dispense rate to dispense a target volume of the wash additive.

Abstract: A scent dispensing assembly for a washing machine appliance includes a scent dispensing box defining a reservoir for receiving a scented material, such as aromatic oil. An ultrasonic diffuser may be mounted to a bottom of the scent dispensing box for generating a flow of scented vapor from the scented material which may pass into the wash chamber through an aperture in the scent dispensing box. The flow of scented vapor may be drawn into the wash chamber by spinning the wash basket to generate air circulation. In addition, a fan may be fluidly coupled with the reservoir for urging the flow of scented vapor into the wash chamber.
