  • Patent number: 5432969
    Abstract: A washing method and a washing apparatus capable of obtaining a washing or cleaning effect by mechanical energy obtained by cavitation phenomena or nonlinear oscillation of micro air bubbles generated during the resonance of a multi-phase medium using low frequency waves. The resonance phenomenon becomes accelerated and uniform by virtue of the injection of air bubbles in the tub or the provision of a sonic or ultrasonic oscillation unit, thereby enabling a superior washing performance to be obtained. Since the present invention eliminates use of any pulsator, it is possible to considerably reduce the phenomenon that clothes get twisted or tangled. As a result, few damage of clothes is generated. Moreover, the electric power consumption in washing or cleaning is greatly reduced.

  • Patent number: 4819459
    Abstract: A front loading cleaning machine may be operated in a normal manner by opening the front door and loading clothes to be washed. When servicing is required, the entire unit may be tipped forwardly about 90 degrees so that the front door is next to the floor. This makes the rear of the machine unit uppermost and exposes the drive mechanism mounted thereon. The drive mechanism may then be readily serviced because the mechanically moving parts are exposed on the upper portion of this machine unit. After servicing, the machine may readily be tipped back to its upright position, ready for normal operation. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

  • Patent number: 4787121
    Abstract: An appliance hinge having internal stop mechanisms. The hinge has a first member which provides a thin bearing surface on both sides of a formed cylindrical segment on the back lip of the door. The second hinge member is a molded block which mounts on the floor of the door recess on the appliance cabinet top, and has a cylindrical shaped guide slot for receiving the first member in sliding engagement. The first and second hinge members are snapped together to prevent disengagement during assembly. When the door is rotated about the hinge axis, the bearing surfaces of the cylindrical segment slilde along the guide slot until the door contacts the back lip of the slot and the edge of the cylindrical segment contacts the terminating surface of the guide slot. Cooperatively, these two stop mechanisms distribute the strain of a relatively strong opening force.

  • Patent number: 4535610
    Abstract: A top loading clothes washer adapted for installation under a fixed or stationary upper structure such as a stacked dryer or countertop wherein the washer is pivotable to a forward tilt-out position providing access to its top. The bottom front of the washer is truncated and the pivot axis which is defined by a stable base is behind the truncation and in front of the center of gravity of the washer. A latch is provided to lock the washer in its upright washing position. The latch is releasable by an operator actuated control provided the water level in the tub is below a predetermined level. Accordingly, forward tilting of a full tub is prevented. Also, the operator actuable control energizes a mechanism which assists in the forward tilting of the washer thereby reducing the pull force required of the operator. More specifically, a biased hinge creates a backward torsion on the washer to provide increased stability during a spin cycle and the mechanism functions to counteract the torsion.
