A household appliance for performing a useful cycle of operation on a physical article may have a treating chamber for holding the physical article during performance of the useful cycle of operation. The household appliance may include a temporary controllable device located within the treating chamber where the temporary controllable device may be communicated with via a signal relay.

A dishwasher includes a controller controlling a cleaning cycle, a screen system for filtering a wash fluid, a circulation chamber and a collection chamber in fluid communication with the circulation chamber via a screen arrangement, a circulation pump for circulating the wash fluid and a drain pump for pumping out the wash fluid. During the cleaning cycle, to detect blockage in the screen arrangement, a degree of transmission in the circulation chamber filled with wash fluid is determined with an optical turbidity sensor in a first measuring step. The wash fluid is then pumped out of the collection chamber and the degree of transmission in the circulation chamber is again determined in a second measuring step. The change in the degree of transmission from the first measuring step to the second measuring step is then evaluated.

A dishwasher according to an embodiment of the disclosure may include: a cabinet; a tub disposed in the cabinet; a sump disposed below the tub; a deionizer comprising at least one electrode configured to produce soft water using raw water supplied from a water source, and supply the soft water to the sump; a plurality of flow paths including at least one pipe and/or at least one hose configured to allow the raw water, the soft water, and used water collected in the sump to flow; a plurality of valves disposed in each of the plurality of flow paths; and a controller including at least one processor, comprising processing circuitry, individually and/or collectively, configured to control the plurality of valves to allow the deionizer to be regenerated using the raw water or the used water, in at least one of a washing process or a rinsing process.

A method includes starting cleaning program stored in memory of control device of dishwasher by start signal triggered on input device of the dishwasher, detecting current actual value of state variable in the dishwasher by sensor, comparing the detected actual value with reference value of relevant state variable stored in the control device, determining parameter and/or parameter value associated with the parameter based on the comparison, outputting output signal associated with the parameter and/or the parameter value on output device, detecting adjustment signal associated with the output signal, generated in response to input on the input device or on input device associated with the dishwasher, and associated with the parameter and/or the parameter value, and continuing to run the cleaning program with original program configuration, modified program configuration, or suspend strategy for ending the cleaning program, according to the adjustment signal.

The invention concerns a household appliance, the household appliance comprising: a washing chamber for washing of items to be cleaned; a water system configured to feed water to and from the washing chamber for cleaning and/or rinsing of the items therein; wherein the water system comprises a UV-treatment chamber for disinfection and/or sterilization of water to be fed to the washing chamber during operation of the household appliance, wherein the UV-treatment chamber is provided with at least a first UV-light source arranged to direct UV-light towards water present in the UV-treatment chamber. The UV-treatment chamber is further provided with at least a first UV-light reflector. The invention also concerns a method for operating a household appliance.

A calibration method for a sensor module of a smart cleaning device includes providing a sensor module. The sensor module has a plurality of sensors, a control unit, a switch circuit, a calibration circuit and a measurement circuit. The plurality of sensors comprise at least one turbidity sensor. The method also includes controlling, by the control unit, the switch circuit to be turned on to supply power to the turbidity sensor, in response to a calibration command to the turbidity sensor from a main controller of the smart cleaning device. The method further includes adjusting, by the control unit, an input of the turbidity sensor via the calibration circuit, obtaining an output of the turbidity sensor via the measurement circuit, and adjusting the input based on the output until the output meets a preset range. The method additionally includes sending, by the control unit, a calibration completion information to the main controller.

The present invention relates to a dishwasher which can sense the turbidity of washing water in real time regardless of specific measurement conditions, and thus can effectively identify the progress of an operation, and which can identify the progress of the operation in real time through a turbidity sensor.

A dishwasher includes a washing system configured as a recirculation loop and a dirt discharge system associated with the washing system. The dirt discharge system is associated with a separator apparatus configured so as to separate at least a portion of the washing liquid required to empty a dirt collection region of the dirt discharge system and discharged together with the dirt particles from the dirt collection region from the dirt particles discharged from the dirt collection region and to return the separated washing liquid back to the water circulation of the dishwasher.
