<P>PROBLEM TO BE SOLVED: To provide a fan assembly, particularly a fan heater. <P>SOLUTION: The 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 means for conveying the first portion of the air flow to the at least one air outlet. To cool a part of the casing, the casing includes: means for diverting a second portion of the air flow in a direction away from the at least one heater; and second channel means for conveying the second portion of the air flow along an internal surface of the casing. The second portion of the air flow can merge with the first portion of the air flow within the casing, or can be emitted through at least one second air outlet of the casing, preferably over the external surface of the casing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
