A household dishwasher includes a washing compartment receiving items to be washed, a control device configured to carry out a washing program selected from a number of washing programs for washing the items to be washed in the washing compartment, an optical sensor configured to acquire an optical sensor signal of the washing compartment, a receiving unit configured to receive a start signal from an external control unit for starting the washing program remotely, and an evaluation unit configured to identify a safe operating state of the household dishwasher as a function of the acquired optical sensor signal and to block or release a start of the washing program initiated by the received start signal as a function of the identified safe operating state.

An online system, including a smart laundry machine, which is capable of easily and inexpensively using the smart laundry machine is disclosed. A further extended type of a smart home appliance, an online system including the same, and a method of using the online system are also disclosed. A laundry machine communicates with a server, is remotely controlled by an external terminal through the server, and has a control panel for a user interface. The control panel includes a course selection unit, an option selection unit, a start button, a display unit to display state information of the laundry machine, and a remote service activation input unit to set or cancel remote service activation according to user selection. The remote control is performed only in a case in which the remote service activation is set.

A dishwasher, in particular a domestic dishwasher, includes a dishwasher cavity for receiving an item to be washed. A door or flap is configured to close the dishwasher cavity and movable between an open and a closed position. Associated to the door or flap is a two-stage or multi-stage safety catch for transition between an open and a closed state of the door or flap. A device is provided to capture whether the door or flap is closed or open and to detect a traversal of the two-stage or multi-stage safety catch.

A food equipment device, such as a warewasher, includes a powered component, the powered component being one of a heating element or a pump or a fan, and a power line path for delivering power to the powered component. A contactor is provided for controlling power delivery to the powered component, the contactor including main power contacts connected in the power line path and auxiliary contacts that operate the same as, or opposite to, the main power contacts. A monitoring system is operatively connected to the auxiliary contacts to monitor an open or closed state of the auxiliary contacts and includes a voltage source operatively connected to one of the auxiliary contacts and an electrical sensor for detecting one of (i) a voltage condition of the other auxiliary contact or (ii) a current flow condition between the auxiliary contacts.

What is proposed is a cleaning appliance (110) for cleaning articles to be cleaned (116). The cleaning appliance (110) comprises at least one cleaning chamber (114) and at least one nozzle (123) for applying at least one cleaning fluid (118) to the articles to be cleaned (116) within the cleaning chamber (114). The cleaning appliance (110) also comprises at least one temperature sensor (168), which is arranged in at least one desired jet region (166) of the nozzle (123). The cleaning appliance (110) also comprises a control unit (157), which is designed to analyze at least one sensor signal of the temperature sensor (168) and to evaluate a jet behavior of the nozzle (123) on the basis of the sensor signal.

The present invention relates to a conveyor dishwasherwith at least one final rinse zone with at least one final rinse nozzle for spraying final rinse liquid onto washware, and wherein a metering device associated with the final rinse zone is provided for adding a disinfectant to the final rinse liquid in a metered manner. A sensor device is configured to detect the concentration of disinfectant in the final rinse liquid which is sprayed in the final rinse zone. Furthermore, a control device is configured to compare the value of the concentration of disinfectant which is detected by the sensor device with predefinable concentration values and, in the event of excessively high deviations of the concentration of disinfectant from the predefinable concentration values, to interrupt the dishwashing process or to output a warning signal to an operator.

A batch-type warewash machine includes a chamber for receiving wares to be cleaned, the chamber having a chamber access opening and a single spray zone, with at least one spray system for spraying liquid onto wares in the single spray zone. A door is movable between a closed position covering the chamber access opening and an open position away from the chamber access opening to allow wares to be moved in and out of the chamber. A curtain structure is mounted on the machine, the curtain structure located behind the door when the door is in the closed position. The curtain structure remains in position and at least partially covers the chamber access opening when the door is in the open position so as to retain hot moist air within the chamber when the door is moved to the open position upon completion of a ware cleaning cycle.

A dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising an outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit and through the outlet in the rotatable spray arm.

A dishwasher appliance includes a tub defining a wash chamber for receipt of articles for washing, a fluid delivery device configured for delivering wash fluid into the wash chamber, and a camera assembly mounted with a view of the wash chamber including a location where the fluid delivery device is configured for delivering the wash fluid. A controller is configured to obtain consecutive images of the wash fluid in the wash chamber, determine whether the fluid delivery device is providing acceptable delivery of the wash fluid into the wash chamber, wherein the determining includes using the consecutive images of the wash fluid to determine whether there are differences in the wash fluid present in the wash chamber, and initiate corrective action if the fluid delivery device is not providing an acceptable delivery of the wash fluid into the wash chamber.

A dishwasher and method of operating a dishwasher according to a cycle of operation are described herein. The dishwasher includes a tub at least partially defining a treating chamber, a rotatable spray arm comprising a nozzle outlet, and a liquid supply conduit fluidly coupled to the spray arm. A pump can be fluidly coupled to the liquid supply conduit and operated to flow liquid through an aperture in the liquid supply conduit.
