Patent number: 10662568Abstract: A suspension unit assembly comprises a strut having a first end and a second end and a coupling disposed at the first end of the strut. The coupling has a strut part connected to the strut and a mounting part configured to tilt relative to the strut part of the coupling. A spring is disposed about the strut, one end of the spring being restrained relative to the mounting part of the coupling so that tilting movement between the strut part and the mounting part of the coupling causes the spring to deform and provide a return force that acts to return the coupling to an equilibrium position.Type: GrantFiled: June 1, 2017Date of Patent: May 26, 2020Assignee: Fisher & Paykel Appliances LimitedInventor: Russell Joseph Jackson

Patent number: 9963817Abstract: A vibration isolator suitable for isolating and/or dampening vibrations generated in a vibrating machinery component such as a motor or pump so as to minimise the unwanted effects (such as audible secondary sounds) of those vibrations. The isolator may be installed in a home appliance such as a laundry washing machine and may be a separate, unitary component installed between a motor/pump and the structure of the laundry machine or may be installed between a mounting bracket of the motor/pump and the laundry machine. Alternatively, the isolator may be integrally formed with a pump/motor mounting bracket, on upper and/or lower surfaces of a mounting flange. The isolator is preferably formed from a substantially incompressible material and in one preferred embodiment has a washer-like form with a central opening at least partially surrounded by a tubular ridge with a plurality of radial projections extending outwardly and/or inwardly from outer/inner surface(s) of the tubular ridge.Type: GrantFiled: June 20, 2016Date of Patent: May 8, 2018Assignee: Fisher & Paykel Appliances LimitedInventors: Brian Paul McLean, Valentin Pierre Nouguier

Patent number: 9220392Abstract: A filter for use in a washing appliance is disclosed. The filter includes an inlet, an outlet, a filter chamber and a mesh strainer placed between the inlet and outlet. The mesh strainer strains water or liquid flowing into the filter as the water flows into the inlet and out of the outlet. The mesh strainer filters out particulate matter from the flow through the filter. The liquid flowing into the filter flows across the mesh to clean the filter and dislodge at least some of the particulate matter trapped in the mesh. The filter chamber includes at least one baffle within it. The baffle divides the filter chamber into an upper portion and lower portion. The particulate matter washed off collects in the lower portion of the filter chamber due to rotational flows created in the filter due to the filter chamber boundaries and the baffles.Type: GrantFiled: November 26, 2009Date of Patent: December 29, 2015Assignee: FISHER & PAYKEL APPLIANCES LIMITEDInventors: John Richard James Morrison, Anthony John Green
