A method for the dosing of cleaning agents in cleaning machines, including the steps: receiving control information items, wherein the control information items are dependent on information 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 about the cleaning machine can be determined via a sensor-based automatic recognition.

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.

A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

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

A dosing method for dosing a chemical product, particularly a detergent, in a dishwasher includes detecting a first loading signal of a washing liquid in a washing tank of the dishwasher; dosing a first quantity of chemical product in the washing liquid to obtain a washing mixture; detecting a conductivity value of the washing mixture at a first loading condition of the dishwasher; storing a conductivity threshold value equal to the conductivity value of the washing mixture at a first loading condition; and dosing of a further quantity of chemical product in the washing mixture at an operation condition of the dishwasher in such a way to adjust a further conductivity value of the washing mixture detected in the operating condition until reaching the conductivity threshold value.

A dishwasher may include a washing chamber and a wash arm arrangement having a wash arm rotatably arranged in the washing chamber, and a satellite spray device arranged on the wash arm. The dishwasher may include at least one sensor configured to sense a rotational position of the wash arm and a control unit configured to monitor consecutive sensed rotational positions of the wash arm. The control unit may be configured to calculate a rotational speed of the wash arm based on an elapsed time and a rotational distance between two sensed rotational positions, and may be configured to estimate a current rotational position of the wash arm based on an elapsed time since a previously sensed rotational position and the calculated rotational speed. The control unit may adapt the pumping intensity of a pump of the dishwasher based on the estimated current rotational position of the wash arm.

In a method for operating a household appliance having a user interface for operation of the household appliance by a plurality of users, a number of predetermined usage actions of a particular user of the plurality of users when operating the household appliance is registered in a user-specific manner, and a user-specific control surface is provided by way of the user interface for the particular user on the basis of the usage actions of the particular user as registered in a user-specific manner.

According to one embodiment of the present disclosure, a dishwashing machine includes a tub accommodating tableware, a nozzle assembly spraying washing water, a vane assembly changing a traveling direction of the washing water sprayed from the nozzle assembly to move linearly inside the tub, a user interface for receiving a divided washing zone selected by a user, and a control unit controlling movement of the vane assembly to wash the selected divided zone by the washing water including the changed traveling direction.

A dishwasher includes a tub that accommodates dishes; a nozzle assembly that sprays washing water; a vane assembly that is moved between a first position and a second position of an inside of the tub and changes a progression path of the washing water so that the sprayed washing water can be directed toward the dishes; and a controller that moves the vane assembly to the second position if the vane assembly is disposed at the first position. When a linear washing portion washes a small quantity of dishes by spraying washing water while making a reciprocal motion in part of an inside of a washing chamber, a washing time can be reduced, and concentrated washing can also be performed.

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.
