  • Patent number: 4988149
    Abstract: A front-serviceable appliance of the type requiring removal of a cabinet top for servicing. The invention permits the use of a horizontally sliding cabinet top. The appliance includes resilient retaining clips that secure the cabinet top and simultaneously prevent accidental disconnection of a cabinet-top actuated electrical connection. Also included in a mounting for a water-inlet vacuum-break that allows the vacuum-break to pivot downwardly to provide clearance for sliding of the cabinet top for removal or replacement. The sliding cabinet top reduces vertical space required to gain service access, while the electrical connection eliminates the need for a separate fastener, thus greatly simplifying cabinet top actuation.

  • Patent number: 4972687
    Abstract: A combined appliance for washing and drying laundry of the over/under type. The appliance includes a washer tub wherein the ratio of the tub diameter to the tub depth is approximately 1.3, and further includes a dryer having a drum wherein the ratio of the drum diameter to the drum depth is approximately 1.3. A washer basket is disposed in the washer tub, and the ratio of the dryer drum volume to the capacity of the washer basket is approximately 2.4. The volume of the dryer drum is greater than 4 cubic feet, and the washer basket capacity is greater than 2 cubic feet. The rearwardmost extent of the washer tub is closer to a vertical centerline of the dryer drum than to a rear of the dryer drum, thus enhancing access to the interior of the washer and facilitating transfer of the laundry from the washer to the dryer.
