Abstract
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.
Claims24
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 upstream of the second fluid outlet, 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, and 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.
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.
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.
