Patent number: 10344773Abstract: A fan assembly includes a motor-driven impeller for creating an air flow, a casing including an interior passage for receiving the air flow, and a plurality of air outlets for emitting the air flow from the casing. The casing defines and extends about an opening through which air from outside the casing is drawn by the air flow emitted from the air outlets. The fan assembly also includes at least one heater for heating at least a first portion of the air flow, and means for diverting at least a second portion of the air flow away from said at least one heater. The plurality of outlets includes at least one first air outlet for emitting the relatively hot first portion of the air flow and at least one second air outlet for emitting the relatively cold second portion of the air flow.Type: GrantFiled: October 3, 2014Date of Patent: July 9, 2019Assignee: Dyson Technology LimitedInventors: John David Wallace, Chang Hin Choong

Patent number: 10145583Abstract: Heating apparatus includes an air inlet, a plurality of air outlets, an impeller, a motor for rotating the impeller to draw air through the air inlet, a user interface for allowing a user to select a rotational speed of the motor from a user selectable range of values, and a plurality of heater assemblies each comprising at least one positive temperature coefficient (PTC) heating element for heating air passing from the air inlet to a respective air outlet. The magnitude of a current drawn by the heater assemblies is detected, and the rotational speed of the motor is controlled independently from the rotational speed selected by the user depending on a characteristic of the current drawn by the heater assemblies.Type: GrantFiled: April 3, 2013Date of Patent: December 4, 2018Assignee: Dyson Technology LimitedInventors: Yuen Kee Leow, Jun Hong Lee, Ying Fang Tan, I Made Artha Yoga Ajnyana, John David Wallace
