A water-conducting household appliance has a closable treatment chamber, in order to treat articles therein, at least one chamber water inlet into the treatment chamber, at least one sump under said treatment chamber, a coarse particle filter for separating coarse particles having a size ≥5 mm from water exiting from the sump, wherein the coarse particle filter has a coarse particle filter inlet, a coarse particle filter water outlet and a coarse particle filtrate outlet. According to the invention, exactly one pump having a pump inlet and a pump outlet is provided for the entire household appliance, said pump being connected downstream of the sump and the coarse particle filter water outlet. Water lines, valve devices and a discharge outlet from the household appliance are also provided, wherein a water line leads from the coarse particle filter water outlet to the pump or to the pump inlet.

A washing machine includes a casing having an input port which is formed in a front surface thereof and to which laundry is inputted; a tub which is disposed in the casing to contain fluid, and has an opening communicating with the input port; a drum which is rotatably disposed in the tub, and contains the laundry; a pump which pumps water discharged from the tub; a circulation conduit which guides the water pumped by the pump; an annular gasket which forms a channel connecting the input port and the opening of the tub, and has a plurality of nozzles for spraying water into the drum on an inner circumferential surface defining the channel; and a nozzle water supply conduit which is fixed to the gasket, and supplies the water pumped by the pump to the plurality of nozzles.

A laundry appliance door assembly with an integrated user interface is adapted to eliminate any visible mechanical fasteners to create an aesthetically smooth appearance. The door assembly includes an inner door assembly to support an inner window, an intermediate door frame that houses the user interface controller, and an outer door screen with embedded touch film. The inner door assembly carries a hinge with wiring harness assembly and the intermediate door frame is adhesively bonded with the inner door assembly to form an intermediate door assembly. The outer door screen includes a touch film adhesively attached to the screen with a roller apparatus of low durometer. The outer door screen is then adhesively bonded to the intermediate door frame to complete the door assembly. The intermediate door frame is adhesively bonded to the front of the inner door assembly along with a hinge cover and a handle cover adhesively bonded to the back of the inner door assembly hides any visible mechanical fasteners of the door assembly.

System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

A method of operating and a laundry treating appliance, including a rotatable drum at least partially defining a treating chamber into which laundry may be placed for treatment according to a cycle of operation, a processor programmed to at least as the laundry is being placed in the treating chamber, at least one of measure, sense, analytically determine, estimate, or receive as an input a first load size of the laundry in the treating chamber to define a determined first load size and select at least one of a color or an intensity corresponding to the determined first load size to define a first light setting.

A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. Each of the first and second moving masses includes a single mass made of a metal material or a mass in which a plurality of thin metal plates are coupled to overlap each other, and the first moving mass has a mass greater than that of the second moving mass.

A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, a tub accommodating the drum, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a support plate coupled to the cabinet, a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet, and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. A support comes into line or point contact with a bottom surface of the first moving mass so that the first moving mass has reduced attenuation ratio in comparison to the second moving mass.

A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, a tub accommodating the drum, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a support plate coupled to the cabinet, a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet, and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. To absorb the oscillation, a time point at which the second moving mass starts relative motion with respect to the support plate is different from that at which the first moving mass starts relative motion with respect to the support plate.

A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, a tub accommodating the drum, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a support plate coupled to the cabinet, a moving mass provided on the support plate, and a slider interposed between the moving mass and the support plate to apply a frictional force to attenuate a reciprocating motion of the moving mass.
