A dishwasher includes a controller for executing a washing program for washing a dirty item to be washed, and a receiving unit for receiving a sensor signal indicative of a dirt type adhering to the dirty item to be washed from a plurality of dirt types, with each of the dirt types being determined by a dirt parameter matrix, in which each position is assigned to a dirt parameter. A determining unit determines the dirt type adhering to the dirty item to be washed as a function of the received sensor signal, with the controller executing the washing program as a function of the determined dirt type.

A dishwasher thermometer captures temperature data of temperature sensed within a dishwasher during a wash cycle. The dishwasher thermometer includes a wireless communication interface that transmits the captured temperature data to one or more of a server and a monitor device. When the captured temperature data indicates that the wash cycle did not achieve defined temperature threshold(s), an alert is generated at the server and/or the monitor device indicating that the wash cycle did not meet appropriate washing conditions. In embodiments, the temperature data may be accessible to a third party for certification of the dishwasher wash cycle.

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.

A system includes a dishwasher including a receptacle for an item to be washed, and a control device for carrying out a washing program, which can be parameterized by a number of different washing program parameters. An image-capturing device captures an image of the receptacle and an image analysis unit classifies the item to be washed in the receptacle in dependence on the captured image of the receptacle and to output a classification result to the control device. The control device is designed to parameterize the washing program depending on the classification result.

A household appliance includes a control device configured to carry out a treatment program from a plurality of treatment programs, with each of the plurality of treatment programs being determined by a plurality of program parameters, an output unit configured to output a feedback survey in accordance with a feedback cycle to a user of the household appliance, and an adjustment unit configured to adjust the feedback cycle depending on a user feedback detected by an input means.

A dishwasher includes a tub with an outlet for humid air to flow out from the tub, and an inlet for dry air to flow into the tub; and a drying system with an air circuit and an adsorbent component disposed between an air inlet and an air outlet in the air circuit. The adsorbent component includes a water harvesting nanomaterial for absorbing water from the humid air and releasing water upon regeneration. During a drying cycle, the air circuit draws humid air from the tub such that the adsorbent component absorbs moisture from the humid air to form a dry air stream, and during a subsequent wash cycle, the air circuit is blocked from receiving air flow such that latent heat can be transferred to the adsorbent component via conduction, convection, or both, to regenerate the water harvesting nanomaterial.

A method for operating a dishwasher appliance includes receiving data indicating a status of hot water within a water heater appliance, receiving data indicating a status for a cycle of a dishwasher appliance, and initiating a start for the cycle of the dishwasher appliance in response to the data indicating the status of hot water within the water heater appliance indicating available hot water.

Image classification is used to dynamically control one or more wash parameters in an automated cleaning machine. An imaging device installed in the wash chamber of the cleaning machine captures one or more image(s) of articles to be cleaned at various times throughout a cleaning process. A computing device analyzes the captured image(s) to classify the images as to an article type and a rack volume. Based on the article type classification and the rack volume, the computing device dynamically controls one or more parameters of the cleaning process to achieve a satisfactory cleaning and/or sanitizing result.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a circulation pump, a pressure sensor, and a controller. The circulation pump may be in fluid communication with a wash chamber defined by the tub. The pressure sensor may be upstream of the circulation pump. The controller may be configured to initiate a washing operation including activating the circulation pump, detecting movement of the door from a closed position, detecting return of the door to the closed position, calculating a modified time period for flood detection, determining pressure at the pressure sensor exceeds a pressure threshold following detecting return of the door to the closed position, initiating the modified time period in response to determining pressure at the pressure sensor exceeds the pressure threshold, and directing the circulation pump based on measuring the elevated pressure and expiration of the modified time period.

A dishwasher includes an image-based detergent sensor that in some instances is configured to sense a type of detergent for use in optimizing a wash cycle based upon the type of detergent, and that in some instances is configured to direct one or more controllable sprayers to facilitate dissolution or mixing of detergent into a wash fluid during a wash cycle.
