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.

The present invention relates to a pressure wall for a centrifugal pump for fluid having substantially the shape of a disc, the disc-shaped pressure wall having a central axis, the pressure wall comprising: a top surface; and a bottom surface opposing the top surface; wherein the top surface includes an inner surface section and an outer surface section, wherein the inner surface section extends radially from the central axis and is recessed to form a central recess; and wherein the outer surface section includes an inner circumferential edge portion and an outer circumferential edge portion, wherein the inner circumferential edge portion is located closer to the central axis than the outer circumferential edge portion, and wherein the outer circumferential edge portion is located higher than the inner circumferential edge portion with respect to a plane perpendicular to the central axis and passing through the inner circumferential edge portion.

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.

Disclosed herein is a drain pump driving apparatus and a laundry treatment machine including the same. The drain pump driving apparatus and the laundry treatment machine including the same according to an embodiment of the present invention include a motor to operate the drain pump, an inverter to convert a direct current (DC) power to an alternating current (AC) power by a switching operation and output the converted AC power to the motor, an output current detector to detect an output current flowing to the motor, and a controller to control the inverter, wherein the controller may calculate a speed ripple of the motor based on the output current and performs a control operation based on the calculated speed ripple of the motor to change a speed of the motor.

A laundry treating appliance includes a treating chamber provided for receiving laundry for treatment, a controller having a memory in which is stored a set of executable instructions including a set of cycles of operations. The laundry treating appliance also includes a user interface operably coupled with the controller and having a touchscreen configured to provide an input and output function for the controller.

A washing machine includes a cabinet; a tub in the cabinet; and a detergent supply apparatus which supplies detergent to the tub and includes: a housing; a detergent box configured to be inserted into the housing and thereby docked to the detergent pump so that detergent in the detergent box is suctionable by the detergent pump and then dischargeable by the detergent pump into the housing and configured to be withdrawn from the housing and thereby undocked from the detergent pump; and an auxiliary tank which in the housing, configured to store water, and to, when the detergent box is being withdrawn from the housing, drain water stored in the auxiliary tank to a bottom of the housing so that detergent from the discharge pump falls into the water on the bottom of the housing.

A laundry treating machine includes a case, a tub, a drum, a drain pump housing, and a drain pump motor, wherein a plurality of fastening protrusions that are formed at one of the drain pump housing and the drain pump motor are inserted into a plurality of fastening grooves that are formed at the other of the drain pump housing and the drain pump motor, and wherein a length of one fastening protrusion is formed to be different from lengths of the other fastening protrusion such that the drain pump housing and the drain pump motor is prevented from being assembled wrongly.

A washing machine appliance may include a cabinet, a tub, a lid, and a filter assembly. The cabinet may define an opening. The tub may be disposed within the cabinet for the receipt of articles therein. The lid may be movably mounted to the cabinet to selectively cover the opening and restrict access to the tub. The filter assembly may be mounted to the lid to move therewith. The filter assembly may include an assembly box defining a box compartment and an assembly outlet upstream from the tub to direct liquid thereto. The assembly box may be movable relative to the lid. The filter assembly may further include a filter cartridge selectively received within the box compartment to filter liquid upstream from the assembly outlet.

In a laundry treating apparatus, flat surfaces are installed at both sides of a tub for storing water therein, so that a spacing between each of the both sides of the tub and each side of a cabinet is smaller than a spacing between a lower surface of the tub and a bottom of the cabinet. Further, a control panel is disposed between the lower surface of the tub and the bottom of the cabinet.

A laundry washing machine having a washing tub in which a drum for receiving laundry is arranged, a filter, and an outlet duct fluidically connecting the washing tub and the filter. The filter comprises a filter seat and a filter body insertable/inserted on the filter seat, and the filter body is built in a once-piece design as a monolithic body with two hem i-shells that are connected to each other by at least one deformable connection element.
