A dispensing assembly including at least one treating chemistry container configured to store a treating chemistry and selectively fluidly coupled to the treating chamber, a sensor configured to detect a characteristic of the dispensing assembly and output a first signal based thereon, an illumination detector outputting a second signal indicative of ambient illumination and an indicator outputting a human-detectable signal.

A dishwasher includes: a tub which defines a space in which dishes are washed; a sump which accommodates washing water to be supplied into the tub; and a descaling solution supply device which supplies a descaling solution to the sump, in which the descaling solution supply device includes: a main flow path which guides washing water to be supplied to the sump; a solution accommodating unit which accommodates a descaling agent and has a solution outlet through which washing water, in which the descaling agent is dissolved, is discharged to the main flow path; a solution discharge valve which opens and closes the solution outlet; and a branch flow path which branches off from the main flow path, supplies the washing water into the solution accommodating unit, and has an atmosphere communicating port that communicates with the atmosphere.

The present invention relates to a method of controlling a dispenser for dosing a product in a washing machine leading to an optimized dosing result, a dispenser controller programmed with an algorithm to execute the method of the present invention as well as to the use of said dispenser for controlling dosing of a product in a washing machine.

A removable non-integrated treating chemistry dispensing cartridge assembly may emit a signal in response to a predetermined amount of treating chemistry being detected and in response to a predetermined amount of illumination being detected.

A dishwasher having a tub having an open face and at least partially defining a treating chamber for holding dishes during an automatic cycle of operation, a door moveably mounted between an opened position, wherein a user the treating chamber is accessible, and a closed position, wherein the door closes the open face of the tub and dispensing assembly configured to activate an indicator to emit a human-detectable signal in response to a first signal indicating a predetermined amount of treating chemistry and a second signal indicating a predetermined amount of illumination.

A retrofit auxiliary device for distributing cleaning resources to a household cleaning appliance having a treating chamber is described wherein the device can connect to various household cleaning appliances of different makes and models and can learn the flow of water and detergent during various stages of operation and then perform the dispensing itself.

Dispensing techniques utilize existing fluid to dispense a solid block of chemical product concentrate. The solid chemical product concentrate may include, for example, detergents, disinfectants, sanitizers, rinse agents, or other cleaning agents. The dispenser monitors and controls the concentration of the chemical product in a use solution. When the concentration of the use solution falls outside of a target range, the dispenser routes existing fluid from within the system to the dispenser, where it interacts with and dispense a solid chemical product concentrate, thus raising the concentration of the chemical product in the use solution. In a dishmachine application, the existing fluid may include post wash or rinse fluid from the dishmachine, or may include use solution from a sump, tank, or other use solution storage container.

A flow through chemical sensor includes a housing having a through passage along which chemical can flow, a sidewall of the housing having first and second openings that communicate with the through passage. A first electrode is mounted on the housing and aligned with the first opening, the first electrode of a plate configuration with a unitary depression that extends through the first opening and to a peripheral edge of the through passage. A second electrode is mounted on the housing and aligned with the second opening, the second electrode of a plate configuration with a unitary depression that extends through the second opening and to the peripheral edge of the through passage. A method of detecting presence or absence of chemical is also provided.

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.

A washing system for determining an operating state of a dishwasher comprises a dishwasher, in particular wherein the dishwasher comprises a dishwasher interface, a dispenser unit, in particular wherein the dispenser unit comprises a dispenser interface, wherein the dispenser unit is connected to the dishwasher for dosing a detergent to the dishwasher, a logic unit, in particular wherein the logic unit is connectable to the dishwasher interface and the dispenser interface, and a current sensor for measuring an electrical current consumed by the dishwasher, wherein the current sensor is connected to the logic unit. By replacing costly water meters by a current sensor, the cost efficiency of the washing system may be increased. In addition, the assembling and maintenance effort of the washing system may be reduced.
