Patent number: 9290882Abstract: The present invention relates to a clutch for a laundry appliance. The clutch selectively connects a laundry vessel to a variable speed drive. A driven member is rotationally coupled to the variable speed drive and a driven member is rotationably coupled to the laundry vessel. The driven member is at least partially rotationally coupled to the driven member by friction. At least one locking element is moveable from an unlocked position to a locking position. The driven member and the driven member are rotationally coupled together once the driven member accelerates to a rotational speed above a first rotational speed, connecting the laundry vessel to the variable speed drive.Type: GrantFiled: August 25, 2010Date of Patent: March 22, 2016Assignee: Fisher & Paykel Appliances LimitedInventors: Geoffrey Paul Batt, Sophie Elizabeth Lane, David Charles Rhodes, Ian Campbell McGill

Publication number: 20120228079Abstract: The present invention relates to a clutch for a laundry appliance. The clutch selectively connects a laundry vessel to a variable speed drive. A driven member is rotationally coupled to the variable speed drive and an un-driven member is rotationably coupled to the laundry vessel. The un-driven member is at least partially rotationally coupled to the driven member by friction. At least one locking element is moveable from an unlocked position to a locking position. The un-driven member and the driven member are rotationally coupled together once the un-driven member accelerates to a rotational speed above a first rotational speed, connecting the laundry vessel to the variable speed drive.Type: ApplicationFiled: August 25, 2010Publication date: September 13, 2012Inventors: Geoffrey Paul Batt, Sophie Elizabeth Lane, David Charles Rhodes, Ian Campbell McGill

Patent number: 8204189Abstract: An appliance having a diagnostic capability includes a tone generator, a controller, a data collection function, memory for storing the collected data, and a transmitter. The transmiter transmits a stream of data derived from the stored data using a carrier signal. The carrier signal is switched on and off according to bits in a stream of data derived from the stored data. The transmission also includes interleaving each bit for transmission with an off period of the carrier. Each off period of the carrier has a duration of at least 100 milliseconds.Type: GrantFiled: August 1, 2007Date of Patent: June 19, 2012Assignee: Fisher & Paykel Appliances LimitedInventors: David Charles Rhodes, Christopher Kimberley Laird

Publication number: 20110185772Abstract: A variable pressure water delivery device having an inlet valve fluidly connected to a reservoir, and connectable to a water supply, the inlet valve is at least operable between an open and closed position. The reservoir has a volume that increases elastically with increasing pressure. At least one outlet valve is fluidly connected to the reservoir and a pressure sensor is actuated by the fluid pressure in the reservoir. A controller receives an output of said pressure sensor and provides control signals to operate said inlet valve according to the output of said pressure sensor, and a desired reservoir pressure parameter.Type: ApplicationFiled: August 15, 2008Publication date: August 4, 2011Inventors: Raymond David Ruthven, David Charles Rhodes, Russell Joseph Jackson

Patent number: 6499321Abstract: A laundry machine has a wash enclosure to which a supply of water is admitted through a hot water valve and a cold water valve. A temperature sensor senses the temperature of the combined water flow from the hot and cold valves or the temperature of the water collected in the water enclosure. The hot and cold water valves are preferably controlled in accordance with a programme executed on a microprocessor. In a wash operation the controller opens the hot water valve and monitors the temperature indicated by the temperature sensor. The controller only opens the cold valve once the sensed temperature has reached or exceeded a threshold temperature. The effect of the cold water contained in the hot water pipes of a household water supply on wash temperature or wash volume is reduced.Type: GrantFiled: December 8, 2000Date of Patent: December 31, 2002Assignee: Fisher & Paykel LimitedInventors: David Charles Rhodes, Adam John Darby

Patent number: 6477867Abstract: A balancing system for a laundry appliance is disclosed, which is particularly suited to horizontal axis washing machines. The system includes force and acceleration transducers at each end of the drum, to detect the imbalance. Several algorithms are disclosed, which calculate the correction required to correct for the imbalance. The correction is implemented using a set of balancing chambers, at each end of the drum. The advantages include the traditional mechanical suspension to be dispensed with, and that the system is capable of adapting to different types of floors.Type: GrantFiled: December 20, 1999Date of Patent: November 12, 2002Assignee: Fisher & Paykel LimitedInventors: Gregory Raymond Collecutt, David Charles Rhodes
