摘要： Disclosed herein is a chemical dosing system for an appliance, such as a laundry washing machine or a dishwashing machine, having a water inlet, the system comprising a meter for determining the volume of water supplied to the appliance, a pump for dispensing a quantity of a chemical to the appliance and a control unit arranged to receive a signal from the meter and to cause to be dispensed to the appliance a volume of chemical that is proportional to the quantity of water supplied to the appliance. The disclosed system may enable a correct quantity of chemical to be automatically dispensed to many types of appliance, without the need to know anything about the appliance, or to derive electrical signal from the appliance.

摘要： A turbidity sensor assembly for a dishwasher appliance is provided. The turbidity sensor assembly measures the turbidity of wash fluid in a manner similar to conventional turbidity sensors, but also includes an integral water level indicator. The water level indicator is an opaque buoyant ball that rises and falls with the water level to provide a water level indication that can be used to shut off the drain pump when the sump is empty. More specifically, when the water level drops below a predetermined level, the opaque ball blocks the transmission of light between the emitter and receiver of the turbidity sensor, thus indicating that the sump is almost empty. As a result, the pump operating during a drain cycle need only operate long enough to drain the sump, and this may be achieved without an additional measuring device or complicated control system.

摘要： A dishwasher includes an independent presoak system which may be activated by a user of the dishwasher. The dishwasher presoak system utilizes a storage tank, supply tubes, and set of nozzles which are independent from components used in a washing cycle such that a presoak detergent is applied to items placed within a washing compartment of the dishwasher without being diluted by a standard wash cycle. As part of the presoak system, the dishwasher features a detection system which allows the user to select an automatic presoak operating state whereby the dishwasher utilizes a sensor to determine if items placed into the washing compartment are sufficiently dirty to need a presoak cycle prior to a washing cycle. The dishwasher further relies on a control system to analyze samples taken of the dirtiness levels of items placed within the washing compartment and determine whether a presoak option is necessary or suggested.
