The invention is directed to an improved pan cleaning machine that has a cleaning section that comprises a plurality of frames for mounting a sequence of interchangeable modular cleaning mechanisms. It can include quick-release mounting arrangements so that cleaning mechanisms can be quickly changed for cleaning different types of pans or to replace brushes or other wearing parts of cleaning mechanisms when they require replacement. In some embodiments, the frames for mounting the cleaning mechanisms can comprise swing arms so that the cleaning mechanisms can be swung away from the cleaning position so that the cleaning mechanism can be removed and replaced without interrupting the operation of the machine. If the machine is stopped, the swing arm can still be used to facilitate access to the cleaning mechanism to reduce the time needed to complete the maintenance or replacement. This also allows the position of the cleaning mechanism in relation to the baking pans to be adjustable during the cleaning process which can permit increased application of brushing forces or prevent overloading and also permits easy jam removal. In addition, the swing arm makes the pan cleaning machine more adaptable for cleaning pans with different depths and customizable. A method of operation and control, including pre-programmed cleaning cycles and various control paradigms is also provided.

A dishwasher, in particular a household dishwasher, includes a dishwasher cavity, a spray apparatus for dispensing washing liquor, and a drive facility including an electric motor designed to actively drive the spray apparatus so as to apply washing liquor to an item to be washed arranged in the dishwasher cavity. The drive facility includes a detection unit for detecting a motor rotational speed of the electric motor. A control apparatus determines a blockage of the spray apparatus in dependence upon the detected motor rotational speed.

Provided are a control method for a dishwasher and a dishwasher. The dishwasher includes a spray rod and a spray rod driver configured to drive the spray rod to rotate. The control method for the dishwasher includes acquiring a predetermined washing signal; controlling the spray rod driver to drive the spray rod to rotate into a predetermined washing region from a current position; and adjusting a parameter of sprayed fluid flow when the spray rod rotates into the predetermined washing region.

The present disclosure relates to a dishwasher. The dishwasher according to an embodiment comprises: a tub having a washing room, in which an object to be washed is accommodated, formed therein; a nozzle which is arranged in the washing room and sprays washing water to the object to be washed, and includes a magnetic body at one end thereof; a coil which his formed to surround a region corresponding to a movable range of the nozzle, and through which an electric current flows according to the rotation of the nozzle; and a controller which controls an operation of the nozzle according to an operation command, and determines an operating status of the nozzle on the basis of a value of the voltage generated in the coil.

A household dishwasher includes a washware receptacle, a holding facility positioned in or on the washware receptacle to hold washware, an actively driven spray arm, and an open-loop and closed-loop control facility designed to influence a rotational movement of the spray arm as a function of a position of the holding facility in or on the washware receptacle so that the spray arm pauses close to the holding facility to apply wash liquor and/or fresh water to the washware held by the holding facility.

The present disclosure relates to a dishwasher. The dishwasher of one embodiment comprises a tub having a wash space in which a wash target is accommodated, a sump being disposed at a lower end of the tub and storing wash water, a wash pump supplying wash water that is accommodated in the sump to a nozzle, a rack being disposed in the wash space and storing a wash target, a nozzle being disposed at a lower end of the rack, being rotated by a repulsive force of wash water that is supplied from the wash pump, spraying wash water to a wash target, and having one end to which a magnetic object is coupled, a sensing module being disposed in an area that corresponds to a range in which the nozzle operates and comprising a Hall sensor that senses a magnetic force generated by the magnetic object, and a controller receiving sensing results from the sensing module and determining one or more of whether the nozzle rotates, a rotation speed of the nozzle and a rotation direction of the nozzle, based on the sensing results, to output an abnormality notification to a user or control wash water that is supplied to the nozzle through the wash pump.

A dishwasher includes a tub, a sump, a wash pump, a rack, a nozzle disposed at a lower end of the rack, the nozzle being rotated by a force of wash water supplied from the wash pump and having a magnetic object coupled to one end of the nozzle so that a first pole and a second pole of the magnetic object face a rotation direction of the nozzle, a sensing module that senses a magnetic force generated by the magnetic object, and a controller receiving sensing results from the sensing module, and determining one or more of a rotation direction of the nozzle, a rotation speed of the nozzle, or whether the nozzle rotates, to output an abnormality notification to a user or control wash water supplied to the nozzle through the wash pump.

A method of operating a pan cleaning system is disclosed in which cleaning parameters are sensed to identify the type of pan being processed. Based on the identified type, a predetermined cleaning routine is automatically selected. Cleaning mechanisms are selectively activated and engaged with the pan, while non-selected mechanisms remain out of service. The system adjusts cleaning speed, motion, and spacing in response to the selected routine and real-time sensor data, including compensating for warped pans. The method further enables servicing of inactive cleaning mechanisms and control of actuation through swing-arm-mounted devices, improving efficiency, adaptability, and maintainability of the cleaning process and the system.

A system adapted to detect rotation of at least two spray arms of a household appliance spaced along a longitudinal axis of the appliance includes a first detection magnet, a second detection magnet and a magnetic sensor. The first detection magnet is arranged on a first spray arm of the at least two spray arms. The second detection magnet is arranged on a second spray arm of the at least two spray arms. A magnetic field direction of the second detection magnet is different from a magnetic field direction of the first detection magnet. The magnetic sensor is arranged in the household appliance and is adapted to sense a motion status of the first detection magnet and the second detection magnet.

The present disclosure discloses a sequential dishwasher, and relates to the technical field of sequential dishwashers and automatic cleaning methods. The sequential dishwasher includes a casing to the bottom of which a drainage pipe is connected, a dish cleaning mechanism, arranged in the casing; a rotary drive mechanism, arranged below the dish cleaning mechanism; a liquid supply mechanism, arranged in the casing and used for providing a detergent or tap water for cleaning of two sides of a dish in a spraying manner; and a control system, configured to control and connect the dish cleaning mechanism, the rotary drive mechanism, and the liquid supply mechanism for a clamping drive, a rotary drive, and a liquid supply cleaning drive during dish cleaning. The present disclosure further provides an automatic cleaning method for dishes. The present disclosure may effectively save detergent consumption and water consumption of cleaning while realizing rapid cleaning of the single dish, and when facing cleaning of a small number of dishes, may complete the automatic cleaning of the dishes more efficiently with more energy saved.
