A dishwasher appliance includes a sump that collects wash fluid and defines a mounting port for receiving a sensor assembly. The sensor assembly includes an adapter that defines a plurality of sensor ports for receiving different sensors, such as a pressure sensor, a temperature sensor, and a turbidity sensor. The adapter is translucent to facilitate turbidity sensing without introducing leak points. In addition, the adapter defines an internal chamber for receiving the wash fluid and an air chamber defined above the internal chamber to prevent direct contact between the wash fluid and the pressure sensor.

The present disclosure relates to a dishwasher and a method of controlling the same. The dishwasher may determine an amount of foam in a wash space using a turbidity sensor measuring a turbidity value of wash water. Additionally, the dishwasher may perform a foam removal operation based on the amount of the foam in the wash space. In this case, the turbidity value measured by the turbidity sensor may be used. The foam removal operation may include a drainage operation, a water supply operation, and a wash operation that are consecutively performed, and may be performed in one or more of a pre-wash course, a main wash course, and a heating and rinsing course.

An artificial intelligence dishwasher including a dish rack on which dishes are arranged, a spray nozzle configured to spray washing water toward the dishes, a washing pump configured to feed washing water stored in a sump to the spray nozzle, a washing motor configured to drive the washing pump, a camera configured to capture the dish rack to obtain a dish arrangement image, and a processor configured to provide the dish arrangement image to a dish recognition model to obtain dish information included in the dish arrangement image, determine a washing cycle for the dishes based on the dish information, and control driving of the washing motor according to the determined washing cycle is provided. A dishwashing method is also provided.

An on-demand glasswasher comprises a wash tank; a fluid level sensor assembly that includes an ultrasonic sensor assembly positioned within the wash tank; at least one microprocessor connected to the ultrasonic sensor assembly; and a memory device coupled to the at least one microprocessor, the memory device storing processor-executable instructions which, when executed by the at least one microprocessor, configure the microprocessor to receive, from the ultrasonic sensor assembly, ultrasonic signals; and analyze the ultrasonic signals to determine a level of fluid in the wash tank.

A method for the dosing of cleaning agents in cleaning machines includes the steps: receiving the control information items; wherein the control information items are dependent on an information item about a cleaning machine; determining the progress of a cleaning operation; dosing of cleaning agent depending on the received control information items and the determined progress of the cleaning operation; wherein the information item about the cleaning machine can be manually input via a user interface.

Color changing alkaline warewash detergents containing a pH sensitive indicator are disclosed. In particular, the warewash detergents can change color in alkaline environments. As the soil level increases or detergent decreases, a color change indicates that the warewash machine needs to be drained and refilled. Methods of employing the color changing alkaline detergent compositions are also disclosed.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a drain pump, a turbidity sensor, and a controller. The tub may be positioned within the cabinet and defining a wash chamber for receipt of articles for washing. The spray assembly may be positioned within the wash chamber. The drain pump may be in fluid communication with the wash chamber. The turbidity sensor may be mounted within the cabinet. The controller may be in operative communication with the turbidity sensor and the drain pump. The controller may be configured to initiate a wash operation. The wash operation may include initiating a rinse cycle, obtaining an image of the wash chamber, determining calibration viability for the turbidity sensor based on the obtained image, and adjusting a calibration state of the turbidity sensor based on the determined calibration viability.

A method of operating an appliance including determining user satisfaction with an operation cycle, adjusting at least one operational parameter of the cycle based on the user satisfaction, and incorporating the adjusted operational parameter into a subsequent cycle is disclosed along with the apparatus including a processor configured to perform the method.

A fluid-driven chemical product dispensing system dispenses fluid chemical product concentrates. The dispensing system includes a fluid drive unit powered by flow of a fluid, such as a diluent, and a pump which delivers the fluid chemical product concentrate from a supply to a destination. Upon exit from the fluid drive unit, the diluent is also delivered to the destination, where it mixes with the dispensed fluid chemical product concentrate to form a use solution. The dilution ratio of the volume of fluid chemical product concentrate dispensed per unit time versus the volume of diluent exiting the drive unit per unit time is constant over a defined range of diluent flow rates.

An ozone sanitizing circulating water apparatus and method using a recirculating water pickup, pump, and water quality sensors for providing a water stream to a mixing venturi that is also connected to ozone generators to supply the water to a dispensing faucet. A capturing hood is flowably connected to a fan and an ozone neutralization system to capture and render inert any excess ozone generation. A fresh water valve, user inputs, operation indicators, and ozone generators are all connected to a control system for monitoring and control of the system to maintain safe and effective operation.
