US 12,458,195 B2 · Dynamic dispensing system

Abstract

Provided herein are systems, methods, apparatus, and computer program products relating to a dynamic dispensing system. Embodiments may include a dishwasher including a washing chamber, a water supply, an additive supply, and a plurality of fluid supply lines that provide fluid communication between the water supply and the washing chamber and the additive supply and the washing chamber. The dishwasher includes one or more pumps that direct additives stored in the additive supply to the washing chamber and water from the water supply to the washing chamber. The dishwasher further includes a tank sensor within the washing chamber and a controller communicably coupled to the controller. The controller may receive and analyze signals from the tank sensor to determine an additive concentration within the washing chamber and cause additive or water to be added to the washing chamber in response to the signal.

Dependent claims

A dishwasher, comprising:

a washing chamber;
an additive pump;
a reservoir;
an in-line sensor fluidically disposed between the reservoir and the washing chamber;
and
one or more inboard controllers within a housing of the dishwasher, the one or more inboard controllers configured to:
cause the additive pump to deliver an additive from the reservoir to the washing chamber;
detect, via the in-line sensor, a signal indicative of a conductivity of the additive upstream of the washing chamber;
based on the signal, determine an error associated with the additive;
and
generate an alarm based on the error.
