An appliance, such as a hairdryer, includes a body having a second annular wall extending about a first annular wall which at least partially defines a bore extending through the body. A fluid flow path extends through the bore from a first fluid inlet of the appliance to a first fluid outlet of the appliance. A primary fluid flow path extends at least partially through the body from a second fluid inlet of the appliance to a second fluid outlet, and comprises, within the body, a first section and a second section in which a heater is located. The first section is arranged to direct fluid over an internal surface of at least one of the annular walls. The first section is arranged upstream of, or in parallel with, the second section.

The hairdryer of claim 2, comprising a fan unit located in the fluid flow path, and wherein the fan unit is located downstream of the first section and upstream of the second section. 6. The hairdryer of claim 2, comprising a duct for conveying fluid from the first section to the second section. 7. The hairdryer of claim 6, comprising a handle, and wherein the duct extends through the handle. 8. The hairdryer of claim 1, wherein the primary fluid flow path comprises, within the body, a third section arranged to direct fluid over an internal surface of one of the annular walls. 9. The hairdryer of claim 8, wherein the third section is arranged to direct fluid over an internal surface of the first annular wall. 10. The hairdryer of claim 8, wherein the third section is arranged upstream of the second section. 11. The hairdryer of claim 10, wherein the third section is in parallel with the first section. 12. The hairdryer of claim 8, wherein the third section is in parallel with the second section. 13. The hairdryer of claim 12, wherein the second section and the third section of the primary fluid flow path merge upstream of the second fluid outlet. 14. The hairdryer of claim 1, wherein the second fluid inlet is located in the body. 15. The hairdryer of claim 14, wherein the first annular wall at least partially defines the second fluid outlet. 16. The hairdryer of claim 1, wherein the second fluid outlet is arranged to emit fluid into the fluid flow path. 17. The hairdryer of claim 1, wherein the second fluid outlet extends about the fluid flow path. 18. The hairdryer of claim 1, wherein the second fluid outlet is annular. 19. The hairdryer of claim 1, wherein the second fluid outlet is arranged to emit fluid into the fluid flow path. 20. The hairdryer of claim 1, wherein the second fluid outlet extends about the first fluid outlet. 21. The hairdryer of claim 1, wherein the bore extends from the first fluid inlet through which a first fluid flow enters the hairdryer to the first fluid outlet for emitting the first fluid flow from the hairdryer. 22. The hairdryer of claim 12, wherein the third section is a closed path. 23. A hairdryer comprising a body having a first annular wall and a second annular wall extending about the first annular wall, the first annular wall at least partially defining a bore extending through the body, a fluid flow path extending through the bore from a first fluid inlet through which a first fluid flow enters the hairdryer to a first fluid outlet for emitting the first fluid flow from the hairdryer, a primary fluid flow path extending at least partially through the body and from a second fluid inlet through which a primary fluid flow enters the hairdryer to a second fluid outlet, the primary fluid flow path comprising, within the body, a first section and a second section, and a heater located in the second section of the primary fluid flow path, wherein the first section of the primary fluid flow path is arranged to direct fluid over an internal surface of at least one of the annular walls, wherein the first section of the primary fluid flow path is arranged upstream of, or in parallel with, the second section of the primary fluid flow path, and wherein fluid is emitted from the hairdryer through each of the first fluid outlet of the fluid flow path and the second fluid outlet of the primary fluid flow path. 24. A hairdryer comprising a body having a first annular wall and a second annular wall extending about the first annular wall, the first annular wall at least partially defining a bore extending through the body, a fluid flow path extending through the bore from a first fluid inlet through which a first fluid flow enters the hairdryer to a first fluid outlet for emitting the first fluid flow from the hairdryer, a primary fluid flow path extending at least partially through the body and from a second fluid inlet through which a primary fluid flow enters the hairdryer to a second fluid outlet, the primary fluid flow path comprising, within the body, a first section and a second section, and a heater located in the second section of the primary fluid flow path, wherein the first section of the primary fluid flow path is arranged to direct fluid over an internal surface of at least one of the annular walls, wherein the first section of the primary fluid flow path is arranged upstream of, or in parallel with, the second section of the primary fluid flow path, and wherein the fluid flow path and the primary fluid flow path are isolated within the hairdryer.
