Abstract: A wall-mounted drum type washing machine includes a rear panel forming a rear surface of a cabinet, comprising a water supply device installed to supply wash water and a driving unit to provide power for a washing operation, mounted on a wall surface; a tub in the cabinet to contain wash water, integrated with the rear panel, and having a rotatable drum therein; a box unit connected to a cover unit having a door thereon, forming an outer wall of the cabinet, and coupled to the rear panel and surrounding the tub; a water supply device supplying wash water into the tub through a top surface of the cabinet; and a drain device discharging wash water from the tub to the bottom of the box unit.

Abstract: A laundry treating appliance having a tub having an open face and at least partially defining a treating chamber in which laundry may be received for treatment according to an automatic cycle of operation, a door for closing the open face of the tub, a perforated rotatable drum located within the tub and a method of operating such that the rotation of the drum is accelerated at a rate sufficient to cause an inrush of supplied liquid into the treating chamber from the tub via the perforations that locates a unit dose treating chemistry within the treating chamber.

Abstract: A laundry drum for a laundry treatment machine that is rotatable about an axis, wherein the laundry drum includes a drum jacket made of metal sheet, and wherein the drum jacket has throughflow holes and linear elevations that are distributed in a peripheral direction and that extend transversely to a periphery line. The linear elevations rise at a distance from one another in a straight or curved line from cylindrical regions of the laundry drum. Agitators are disposed on an inner periphery of the drum jacket and the throughflow holes are disposed in the cylindrical regions.

Abstract: A laundry drum on the one hand is to exhibit the advantageous features of structures of the prior art distributed in the circumferential direction, which protrude from the cylinder shape of the drum casing accommodated in the laundry drum, but at the same time however create the basics for their embodiment for advantageous influencing of the laundry movement within the laundry drum during its rotational movement. To this end structures are inventively formed from ring-shaped protrusions distributed in the circumferential direction.

Abstract: A laundry drum for a laundry treating machine, wherein the laundry drum includes a drum cover that has a cylindrical shape and structures that are distributed in a circumferential direction of the drum cover. The structures project from the cylindrical shape of the drum cover that is mounted in the laundry drum. Further, the structures are formed from inwardly bulging linear elevations that extend along a circumferential line.

Abstract: A washing machine and a water level control method thereof that can supply an appropriate amount of water based on the amount of laundry using a conventional water level sensor even when the washing machine has a holeless rotary drum. The water level control method includes supplying water between the water tub and the rotary drum, introducing the supplied water into the rotary drum, discharging the introduced water out of the rotary drum, and detecting the water level of the water remaining in the water tub, and comparing the detected water level with a predetermined water level and, when the detected water level is below the predetermined water level, resupplying water between the water tub and the rotary drum until the detected water level reaches the predetermined water level.

Abstract: A hopper for a laundry machine of the type having a rotating drum includes front, lower, and side walls which cooperatively define a structure having closed bottom and side surfaces, an open rear surface for being disposed in communication with the interior of the drum, and an upper hopper opening for receiving therethrough items for introduction into the drum. A splash shutter is disposed above the hopper opening. The shutter is movable between an open position wherein the hopper opening is exposed for receiving items therethrough, and a closed position wherein the hopper opening is covered for retaining the contents of the laundry machine.

Abstract: An apparatus for a large throughput fabric processing operation including a conveyor belt passing under a row of washers and having an extraction (spinning) apparatus at the end of the belt. The production line involves top loading each washer as required and dumping the batches of fabric on the belt after completing the washing step. The extraction step involves varying the rate of spin and the tilt of the extraction cyclinder in order to maintain an even distribution of fabric and then rocking the extractor to loosen the load from the inside surface of the extractor. Processing oprations to which this invention may be applied include, laundering, dyeing and drycleaning.

Abstract: A drum to be used in the treatment of hides and leathers is fitted with a number of bats, the arrangement of the bats being determined by an imaginary polygon having an even number of vertices. A pair of bats, parallel to each other, are placed at opposite vertices of the imaginary polygon.

Abstract: An apparatus for processing textiles with a mixture of solid bodies and/or liquid, such as stones in a chemical solution or the like, in order for example to achieve a "worn" look, this apparatus being provided with a drum (1) driven for rotation wherein said drum (1) is formed with end walls (4) having a polygonal periphery and abutting number of flat outer wall plates (2) and at least one circular track (8, 9) each of which rolls over at least one pair of wheels (10) supported by a frame (12) so obtaining a rigid and sturdy structure.

Abstract: An apparatus for tanning or dyeing includes a horizontal rotary drum which is rotatably mounted in a frame at only one axle front end thereof. The rotary drum defines a treatment chamber for tanning and dyeing which communicates with a hollow axle for admission and drainage of a liquid treatment medium. Within the interior of the rotary drum, at least two ring pocket sections are provided which are in communication with two connecting lines arranged at the axial front end of the rotary drum and extending in radial direction. With their radially external ends, each connecting line opens into the interior of the associated ring pocket section. The other end of each connecting line extends to the center of the rotary drum which center communicates with associated axial channels within the hollow axle.

Abstract: A wash tub for a front loading clothes washing machine of domestic type is made in a single body, preferably by injection moulding of plastics material. The tub is provided with a cylindrical band having at least two portions of different diameter. In the area of the region where the band changes in diameter, an annular stiffening rib is provided having seats for locking the suspension members of the tub. The rear portion includes in one piece box-like housings, or at least a bracket, capable of being filled with counterweight material or fixed to added ballast masses, respectively.
