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: 8734094Abstract: A fan assembly includes a motor-driven impeller for creating an air flow, at least one heater for heating a first portion of the air flow, a surface diverting a second portion of the air flow away from said at least one heater, and a casing comprising at least one first air outlet for emitting the first portion of the air flow and at least one second air outlet from emitting the second portion of the air flow. To cool an external surface of the casing, at least one second air outlet is arranged to direct at least part of the second portion of the air flow over the external surface.Type: GrantFiled: July 22, 2011Date of Patent: May 27, 2014Assignee: Dyson Technology LimitedInventors: John David Wallace, Chang Hin Choong

Patent number: 8366403Abstract: A fan assembly includes a motor-driven impeller for creating an air flow, at least one heater for heating a first portion of the air flow, and a casing comprising at least one air outlet for emitting the first portion of the air flow, and first channel for conveying the first portion of the air flow to the at least one air outlet. To cool part of the casing, the casing diverts a second portion of the air flow away from the at least one heater, and comprises a second channel for conveying the second portion of the air flow along an internal surface of the casing. This second portion of the air flow may merge with the first portion within the casing, or it may be emitted through at least one second air outlet of the casing.Type: GrantFiled: July 21, 2011Date of Patent: February 5, 2013Assignee: Dyson Technology LimitedInventors: John David Wallace, Chang Hin Choong
