A dishwasher performs a method for providing a notification for replacing a filter. The dishwasher continues to accumulate operation time of an air blowing fan of the dishwasher, and when total accumulative operation time is predetermined time or greater, outputs a notification for replacing a filter through a display or a speaker to determine the timing of the replacement of the filter accurately.

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 system includes a dishwasher having a dishwasher cavity which can be closed by a door. Receptacles are provided for accommodating items to be washed, and a control device carries out a washing program from a number of washing programs for washing items to be washed. An optical sensor records an optical sensor signal of the dishwasher cavity, and a determining unit determines a load state of the dishwasher cavity as a function of the optical sensor signal recorded by the optical sensor. An output unit outputs a positioning recommendation to a user for the purpose of positioning at least one of the items to be washed in one of the receptacles based on the load state determined by the determining unit.

A dishwasher has a housing (10) with a wash chamber (20) and a top wall (204) with a non-planar surface (214;214″) facing downwardly into the wash chamber, the surface having portions (216,218; 226,228) facing downwardly and facing in different horizontal directions (H1,H2; HX,HY,HP,HQ). Nozzles (402) mounted within the wash chamber spray a liquid upwardly within the wash chamber. The surface portions redistribute the upwardly-sprayed water in horizontal directions to provide a more uniform washing action. A portable dishwasher may have a fresh water reservoir (422) and a used water reservoir (430) mounted in the housing beneath the wash chamber. The used water reservoir may be removably mounted in the housing so that the user can remove used wash water by removing the used water reservoir. The portable dishwasher can be used at a location remote from a sink.

A waste storage device and an intelligent management system are provided. The waste storage device includes: a casing, a control module disposed in the casing, a microphone module disposed on an outer surface of the casing, and a moving module electrically connected to the control module. The microphone module is electrically connected to the control module. When the microphone module receives a first audio signal, the microphone module transmits the first audio signal to the control module, the control module analyzes an audio sending direction of the first audio signal, and the control module provides a driving signal to the moving module according to the first audio signal to drive the waste storage device to move in the audio sending direction.

An article-distribution system for a dishwasher is provided having a camera assembly directed at a rack assembly of the dishwasher, a display screen spaced apart from the rack assembly, and a controller in operative communication with the camera assembly and the display screen. The controller may be configured to direct a dishwasher coverage operation. The dishwasher coverage operation may include receiving an image of the rack assembly from the camera assembly, identifying an uncleanable article, presenting the image at the display screen, and overlaying an identifier onto the presentation of the image based on the identified uncleanable article. The step of identifying the uncleanable article may be based on the received image. The uncleanable article may be in in an uncleanable position within the rack assembly.
