Publication number: 20190143069Abstract: A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurised gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.Type: ApplicationFiled: November 9, 2018Publication date: May 16, 2019Inventors: Venkata Subbarao Potharaju, Christie Jayne Stanton, Andrew Paul Maxwell Salmon, Yi-Cheng Sun, Hayden Briscoe, Samuel Frew, Steven John Worthington, Philip John Dickinson, Cameron Jon Haxton

Patent number: 6398197Abstract: A water chamber has a horizontally orientated gas inlet with an elongate flow tube extending into the water chamber from the inner periphery of the gases inlet. An inlet end of the elongate flow tube covers the inlet and an outlet end of the flow tube is spaced from the wall of the chamber. In use the flow tube receives gases supplied to the gases inlet, the gases pass through the flow tube and exit the flow tube at the outlet end distant from the wall.Type: GrantFiled: May 4, 2000Date of Patent: June 4, 2002Assignee: Fisher & Paykel LimitedInventors: Philip John Dickinson, David Wixey
