The invention is a system for cleaning an article comprising: a static nozzle to spray a fluid, wherein the position and the orientation of said nozzle remains unchanged; a robotic arm to grasp and move said article so that said fluid is sprayed on said article; a camera to acquire an image of said article; a processor to execute an algorithm based on said image to determine a cleaning protocol, wherein said cleaning protocol lists time sequence of a plurality of robot positions; whereby said article is cleaned thoroughly in real-time. The invention is a also a system for cleaning an article comprising a wash module having the means to transform a soiled article into a clean article, wherein the position of said wash module remains unchanged; a first module for holding said article, wherein said first module pulls out, rises in height, lowers in height, and pulls back in, wherein said article is loaded or unloaded after said first module rises in height; a second module for holding said article, wherein said second module pulls out and pulls back in, wherein said article is loaded or unloaded after said second module pulls out; whereby said article can be loaded or unloaded comfortably without bending.

A dishwashing apparatus may include a sump. The sump may include a sump pan configured to couple with a wash chamber of the dishwashing apparatus. The sump may include a sump well coupled to the sump pan and configured to collect the liquid from the sump pan. The sump well may include a well inlet in communication with the sump pan. The sump pan may convey the liquid to the well inlet. A recirculation port extending through a first wall of the sump well. A drain port may extend through a second wall of the sump well. The second wall defines a bottom of the sump well. The dishwashing apparatus may include a controller. The controller may monitor electrical characteristics of a pump. The controller may provide a notification if fluid is not flowing through the pump.

Disclosed in the present invention are an energy-saving dishwasher and a control method therefor. The inner container is arranged inside the housing, the inner container is internally provided with a manifold type dish rack for placing dishes and spraying steam to perform steam cleaning on the dishes, and the manifold type dish rack is placed on a supporting frame fixed to the inner container. A water storage tank, a steam/hot water integrated generating device and a water pump are arranged below the inner container, and the steam/hot water integrated generating device includes a generating assembly and a control assembly. The manifold type dish rack is configured to place the dishes and simultaneously sprays steam to clean the dishes. The steam/hot water integrated generating device is configured to generate steam and hot water, heating is performed to generate the steam, and then relative cooling is performed to generate the hot water.

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.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.

A dishwasher is provided in which tableware is capable of being washed with washing water of a high pressure by preventing the pressure of the washing water from dropping. The dishwasher includes a main body in which a washing tub is formed, a sump provided in the main body and storing washing water, a plurality of injection nozzles to inject the washing water into the washing tub, a plurality of flow passages respectively connected to the plurality of injection nozzles, and a distribution apparatus configured to selectively open and close the plurality of flow passages and communicate with the plurality of flow passages, respectively, and including rotary member having a plurality of independent connection passages and a case in which the rotary member is accommodated.

A dishwasher appliance includes a cabinet defining a wash chamber for receipt of articles for washing. The dishwasher appliance also includes a spray arm disposed within the wash chamber and rotatable about an axis. In addition, the spray arm defines an interior and aperture providing selective fluid communication between the interior and the wash chamber. The dishwasher appliance also includes a valve positioned within the interior of the spray arm, and the valve is stationary relative to the spray arm. The spray arm is rotatable between a first position and a second position. In the first position, the valve allows fluid communication between the interior and the wash chamber through the aperture. In contrast, when the spray arm is in the second position, the valve obstructs fluid communication between the interior and the wash chamber through the aperture.

A method for calibrating a cleaning device that has at least one sensor for detecting at least one state variable, including carrying out a calibration measurement, establishing an electronic connection between the calibration sensor and a controller of the cleaning device, and electronically transmitting the reference value to the controller; and comparing the reference value with at least one measurement value of the sensor of the cleaning device and adjusting at least one correction function in accordance with the comparison. At least one state variable is detected and at least one reference value is determined by means of at least one calibration sensor independently of the sensor of the cleaning device. Future measurement values of the sensor of the cleaning device are automatically corrected using the correction function.

A dishwasher includes: a spray module which sprays washing water toward dishes; a sump which supplies washing water to the spray module; a pump which pumps washing water stored in the sump to the spray module; and an air jet generator which receives a part of washing water pumped from the pump to form an air bubble in washing water and discharges the air bubble to the sump, wherein the air jet generator comprises: a decompression portion which decreases a pressure of washing water; an air suction portion which is opened to allow air to flow into the decompression portion; a pressing portion which increases pressure so as to crush the air introduced from the air suction portion; and an air tap which has a plurality of holes configured to crush the air contained in washing water that passed through the pressing portion.
