Abstract: A hairdryer including a heater, a fluid flow path and a thermal fuse wherein the fluid flow path extends from a fluid inlet to a fluid outlet, the heater extends within the fluid flow path from an upstream end of the heater to a downstream end of the heater and the thermal fuse extends across the downstream end of the heater. The heater may be generally cylindrical in shape and the thermal fuse may extend at least partially radially across the downstream end of the heater. The heater may be annular in cross-section and the thermal fuse may extend at least partially radially across the annular downstream end of the heater. The heater may comprise an element, a scaffold around which the element is wound and an outer wall wherein the outer wall extends about the element and the scaffold.

Abstract: An attachment for a hand held appliance, the attachment including an outer wall with a first part which is generally conical in shape, and a fluid inlet into the outer wall, wherein the fluid inlet is formed from a discontinuity in the outer wall. The outer wall may be formed from a first wall and a sleeve. The first wall may define a fluid flow path through the attachment. The sleeve may extend around the first wall forming a second fluid flow path from the fluid inlet in the outer wall, the second fluid flow path extending between the first wall and the sleeve. An outer surface of the sleeve and an outer surface of the first wall may be collinear. The fluid flow path may extend from a first fluid inlet into the attachment to a first fluid outlet. The first fluid inlet may be annular.
