Abstract

Official abstract text for this publication.

A hair dryer comprises a primary air flow path extending from an inlet port provided on a first side of the hair dryer and extending to an outlet port, a water collection member located inward of the inlet port wherein hair being dried is directed against a screen positioned forward of the water collection member, whereby ingress of hair into the interior of the primary air flow path is inhibited.

First claim

Opening claim text (preview).

1 . A hair dryer comprising: (a) a primary air flow path extending from an inlet port provided on a first side of the hair dryer and extending to an outlet port; (b) an air moving member provided in the primary air flow path; (c) the inlet port comprises a screen, whereby ingress of hair into the interior of the primary air flow path is inhibited; and, (d) a water collection member located inward of the inlet port. 2 . The hair dryer of claim 1 wherein the water collection member comprises a water absorbing member. 3 . The hair dryer of claim 1 wherein the water collection member is removably mounted in the hair dryer. 4 . The hair dryer of claim 2 wherein the water absorbing member comprises a sponge. 5 . The hair dryer of claim 1 wherein the water collection member comprises a collection container with an openable outlet port. 6 . The hair dryer of claim 1 wherein the outlet port is provided on a second side of the hair dryer and the second side is axially opposed to the first side. 7 . The hair dryer of claim 1 wherein the air moving member comprises a motor and fan assembly that is operable in a high suction mode and in a high air flow mode. 8 . The hair dryer of claim 7 wherein, in the high suction mode, a fan blade of the motor and fan assembly is in a high suction mode position in which the fan blade is positioned a first distance downstream from a fan blade cowling and, in the high air flow mode, the fan blade is in a high air flow mode positon in which the fan blade is positioned a second distance downstream from a fan blade cowling wherein the second distance is greater than the first distance. 9 . The hair dryer of claim 8 further comprising a handle that is movingly mounted to the body, the handle is moveable from a high suction mode position to a high air flow mode position, the handle is drivingly connected to the fan and motor assembly whereby, as the handle is moved from the high suction mode position to the high air flow mode position, the fan blade is moved from the high suction mode position to the high air flow mode position. 10 . The hair dryer of claim 1 further comprising a water discharge port, the water discharge port is positioned downstream from the water collection member and the air moving member. 11 . The hair dryer of claim 1 further comprising a redirecting member operable between a first position in which a first volume of air travels from the primary inlet port to the primary outlet port and a second position in which at least some of the first volume of air is redirected to travel through a secondary air flow path having a secondary outlet port provided at the first side of the hair dryer. 12 . The hair dryer of claim 11 wherein the secondary outlet port comprises a plurality of secondary air outlets positioned around the inlet port. 13 . The hair dryer of claim 12 wherein the plurality of secondary air outlets direct air inwardly towards a center of the inlet port. 14 . The hair dryer of claim 13 further comprising a heating element in the secondary air flow path. 15 . The hair dryer of claim 14 further comprising an infrared heating element that, in operation, directs infrared heat to a location forward of the inlet port. 16 . The hair dryer of claim 1 further comprising an infrared heating element that, in operation, directs infrared heat to a location forward of the inlet port. 17 . The hair dryer of claim 14 further comprising alighting member providing a first illumination effect when the air moving member is actuated and air is drawn in through the inlet port and a second illumination effect when the air moving member is actuated and air is drawn in through the inlet port and when the heating element is actuated. 18 . The hair dryer of claim 15 further comprising a lighting member providing a first illumination effect when the air moving member is actuated and air is drawn in through the inlet port, a second illumination effect when the air moving member is actuated and air is drawn in through the inlet port and when the heating element in the secondary air flow path is actuated, and a third illumination effect when the air moving member is actuated and air is drawn in through the inlet port and when the infrared heating element is actuated. 19 . The hair dryer of claim 16 further comprising alighting member providing a first illumination effect when the air moving member is actuated and air is drawn in through the inlet port and a second illumination effect when the air moving member is actuated and air is drawn in through the inlet port and when the infrared heating element is actuated. 20 . The hair dryer of claim 1 further comprising a secondary inlet port downstream from the air moving member and a secondary outlet port provided at the first side of the hair dryer.
