FLUID DELIVERY SYSTEM FOR A FRONT-LOAD WASHING APPLIANCE FOR DELIVERING FLUID TO LIFTERS OF THE DRUM
Publication number: 20240102225Abstract: A front-load laundry appliance includes a drum that is rotationally operable within a tub about a generally horizontal rotational axis. A plurality of lifters are coupled to an interior surface of the drum. A fluid delivery path is at least partially defined within the drum and the plurality of lifters. A fluid delivery system delivers fluid into the fluid delivery path in a direction parallel to the generally horizontal rotational axis.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Applicant: WHIRLPOOL CORPORATIONInventors: Marco Angelini, Matteo Carnevale, Massimiliano Daniele, Deepak Gupta, Mauro Mancini, Vaclav Petracek -
Publication number: 20240093418Abstract: A combination washer/dryer appliance is described that includes a tub mounted within an appliance housing and a drum rotatably supported within the tub. A seal assembly that closes an air gap between a rear drum wall and a rear tub wall is mounted to the drum. The seal assembly includes a resilient flap and a travel limiter, which limits the amount of deflection of the resilient flap, thereby defining a maximum deflection limit for the resilient flap.Type: ApplicationFiled: September 19, 2022Publication date: March 21, 2024Applicant: Whirlpool CorporationInventors: Christopher Lee Borlin, Stephen Ostdiek, Vaclav Petracek, Marcel Schmidt

Patent number: 4854135Abstract: A dry cleanable self-lined unfinished lustrous antique satin fabric having good hand, good crease resistance, and a woven look is provided. The fabric is a weft inserted warp knit (wiwk) fabric which has a multiple substrate, a single substrate with foam backing, or a single substrate with an additional sewn lining. The weft yarn is on the face of the substrate, and is a lustrous yarn such as rayon (as when producing non-washable draperies), or acrylic, bright polyester or acetate (as when producing washable draperies). The weft has a density equivalent to between about 36-52 single picks per inch, and at least part of the weft may comprise a novelty yarn. The warp yarn is stitching yarn, in a tricot stitch configuration. The warp yarn is a low-shrinkage filament yarn that is not fully oriented, and has a denier of between about 20-60, and an elongation of at least 15 percent. Non-woven inexpensive polyester substrate may be utilized; if a single layer is utilized it has a maximum weight of 2.Type: GrantFiled: March 24, 1987Date of Patent: August 8, 1989Assignee: Burlington Industries, Inc.Inventors: Vaclav Petracek, Julius Schnegg

Patent number: 4841749Abstract: Aesthetic warp-knit, weft-inserted fabrics are produced having multiple substrate layers, warp yarns extending in the warp-wise direction of the fabric, and weft yarns extending in the weft-wise direction of the fabric. The warp and/or weft yarns are interposed between the multiple substrate layers. Warp stitching yarns forming stitch wales spaced-apart along the warp-wise direction of the fabric and stitched through the substrate layers hold the warp and weft yarns in position relative to one another and relative to the substrates. The substrates may also be provided in juxtaposed relationship to one another so as to increase the opacity, esthetics, and dimensional stability of the resulting fabric. Thermoplastic fibers may be incorporated in the fabric such that upon plasticization and subsequent cooling, they assist in binding of the resulting fabric.Type: GrantFiled: December 30, 1987Date of Patent: June 27, 1989Assignee: Burlington Industries, Inc.Inventors: Vaclav Petracek, Julius R. Schnegg

Patent number: 4504539Abstract: A non-woven fabric is produced ultrasonically from a batt of ultrasonically fusible fibers and reinforcing yarns formed of bi-component fibers. The non-woven fabric produced has a layer of strong filament yarns integrated into the body of the non-woven fabric to increase the strength of the non-woven fabric without delamination of the components, and without degradation of the component yarns. The batt is continuously fed in a first direction toward and past a plurality of ultrasonic vibration sources and anvil means, which produce bonding sites in the fabric formed. A plurality of reinforcing yarns are taken-off a warp beam and laid atop the web prior to its passage into operative association with the vibration sources and anvil means. Energy is supplied to the vibration sources so that bonding of the fibrous batt into a non-woven fabric, and melting of the low-melt component of the reinforcing yarn fibers, takes place.Type: GrantFiled: April 15, 1983Date of Patent: March 12, 1985Assignee: Burlington Industries, Inc.Inventors: Vaclav Petracek, Kenneth Y.
