Hair treatment appliance with accessory tool
A hair dryer has a body having a hair dryer electrical contact. An accessory tool, which has an accessory tool having an accessory electrical contact, is removably mountable to the body. An electrically operable heating element provided in the accessory tool, whereby, when the accessory tool is mounted to the body and the hair dryer is actuated, the electrically operable heating element is energized using power provided by the hair dryer electrical contact.
1 . A hair treatment appliance comprising:
(a) a body having a hair treatment appliance electrical contact;
(b) a first accessory tool removably mountable to the body, the first accessory tool having an accessory electrical contact;
(c) an air flow path extending from a hair treatment appliance air inlet to a hair treatment appliance air outlet that is provided on the first accessory tool;
(d) a motor and fan assembly provided in the air flow path; and,
(e) a first electrically operable heating element provided in the first accessory tool, whereby, when the first accessory tool is mounted to the body and the hair treatment appliance actuated, the first electrically operable heating element is energized using power provided by the hair treatment appliance electrical contact,
wherein the body is provided with a second electrically operated heating element.
2 . The hair treatment appliance of claim 1 wherein the first electrically operable heating element is a resistive heating element.
3 . The hair treatment appliance of claim 1 wherein the first electrically operable heating element is an infrared heating element.
4 . The hair treatment appliance of claim 3 wherein the first accessory tool further comprises an infrared-absorbing target.
5 . The hair treatment appliance of claim 3 wherein the infrared heating element is focused on the infrared-absorbing target.
6 . The hair treatment appliance of claim 3 wherein air exits the first accessory tool in a flow direction, the air exiting the first accessory tool has a cross-sectional flow area, and the infrared heating element emits infrared radiation having an emitted radiation cross-sectional area in a plane transverse to the flow direction that is essentially the same as the cross-sectional flow area.
7 . The hair treatment appliance of claim 3 wherein the infrared heating element emits heat in a radiation pattern, which pattern matches an air flow pattern provided by air exiting the first accessory tool.
8 . The hair treatment appliance of claim 3 wherein radiation emitted through the infrared heating element is directed towards the hair treatment appliance air outlet.
9 . The hair treatment appliance of claim 3 wherein the infrared heating element emits radiation across the entire hair treatment appliance air outlet.
10 . The hair treatment appliance of claim 3 wherein the hair treatment appliance air outlet comprises a plurality of outlet ports and the infrared heating element emits radiation across the plurality of outlet ports.
11 . The hair treatment appliance of claim 1 wherein the first electrically operable heating element is provided in the air flow path.
12 . The hair treatment appliance of claim 1 wherein the first electrically operable heating element is thermally connected to the air flow path.
13 . The hair treatment appliance of claim 12 wherein the first electrically operable heating element is arranged adjacent a contact surface at the hair treatment appliance air outlet.
14 . The hair treatment appliance of claim 12 wherein the first electrically operable heating element is arranged to heat hair adjacent the hair treatment appliance air outlet.
15 . The hair treatment appliance of claim 1 wherein an infrared heating element is arranged to direct infrared radiation to a location that is exterior to the first accessory tool.
16 . The hair treatment appliance of claim 1 wherein an infrared heating element is arranged to direct infrared radiation at hair held adjacent the first accessory tool.
17 . The hair treatment appliance of claim 1 wherein the motor and fan assembly is provided in the first accessory tool.
18 . The hair treatment appliance of claim 1 further comprising a second accessory tool having a second electrical heating element, and air exiting the second accessory tool has a cross-sectional flow area in a direction transverse to a direction of air flow exiting the second accessory tool that is different to a cross-sectional flow area of air exiting the first accessory tool in a direction transverse to a direction of air exiting the first accessory tool.
19 . The hair treatment appliance of claim 1 further comprising a second accessory tool which has an absence of a heating element.
