Abstract
Abstract A combined hot air and steam hair dryer providing for discharge of hot air and steam through the same aperture, comprising a housing, constituting an air chamber, supported on a balancing base, and provided with a discharge aperture at the forward end and an air inlet means at the rear end, with a motor-powered fan in the latter to drive the air towards the aperture. Intermediate the ends of the housing are provided a plurality of heating coils and, forward thereof, adjacent the aperture, a steam generating casing enclosing a heat rod and having discharge holes in the direction of the aperture, with the heat rod, coils and motor interconnected to a lead wire leading to an electric source and simultaneously activated by a switch. The base contains a water reservoir provided with a pump, to which is connected a hollow tubing leading into the casing, with means to inject water from the reservoir thereinto, therein expanding the water into steam, to be sprayed from the discharge aperture with the hot air.

Total Claims: 9
Claim 1
Independent Claim
232 words
A combined hot air and steam hair dryer comprising a hollow housing defining an air flow chamber and provided with a support base, a fan motor disposed in the rear of the housing, a discharge aperture provided in the front of the housing, fan means driven by said motor for drawing air into the chamber through a rear air inlet of said housing and discharging the air through the front aperture, electric heating means to heat the air passing through the air chamber, a steam generating casing within the air chamber in the air flow path through said chamber downstream of said air heating means and adjacent the discharge aperture and provided with openings facing the aperture, electric heating means disposed within the casing for generating steam, a water reservoir removeably secured within the support base, a pump having an inlet communicating with the reservoir, and an outlet connected to a hollow tubing leading from the pump into the steam generating casing, means to activate the pump means to inject water from the reservoir into the casing, the electric heating means within the chamber and within the casing, and the fan motor being connected in a circuit to a lead wire engageable to an electric source, and switch means to energize the circuit, whereby hot air is discharged through the aperture and steam is selectively discharged through the aperture in a spray.

A combined hot air and steam hair dryer comprising a hollow housing defining an air flow chamber and provided with a support base, a fan motor disposed in the rear of the housing, a discharge aperture provided in the front of the housing, fan means driven by said motor for drawing air into the chamber through a rear air inlet of said housing and discharging the air through the front aperture, electric heating means to heat the air passing through the air chamber, a steam generating casing within the air chamber in the air flow path through said chamber downstream of said air heating means and adjacent the discharge aperture and provided with openings facing the aperture, electric heating means disposed within the casing for generating steam, a water reservoir removeably secured within the support base, a pump having an inlet communicating with the reservoir, and an outlet connected to a hollow tubing leading from the pump into the steam generating casing, means to activate the pump means to inject water from the reservoir into the casing, the electric heating means within the chamber and within the casing, and the fan motor being connected in a circuit to a lead wire engageable to an electric source, and switch means to energize the circuit, whereby hot air is discharged through the aperture and steam is selectively discharged through the aperture in a spray.
Claim 3
Dependent Claim
28 words
A hair dryer as described in claim 1, the air inlet comprising a plurality of openings in the wall of the housing adjacent the blades of the fan.
Claim 4
Dependent Claim
37 words
A hair dryer as described in claim 2, the electric heating means to heat the air passing through the chamber comprising a series of electric heating coils connected to the electrical circuit and insulated from the housing.
Claim 5
Dependent Claim
19 words
A hair dryer as described in claim 3, the electric heating means within the casing comprising a heat rod.
Claim 6
Dependent Claim
64 words
A hair dryer as described in claim 1, the pump means comprising a manual pump provided with a piston plunger extending out of the wall of the support base and arranged in engagement with a spring member within the pump, whereby reciprocative compression and release of the piston plunger forces water from the reservoir through the hollow tube and into the steam generating casing.
Claim 7
Dependent Claim
34 words
A hair dryer as described in claim 1, the pump means comprising an electrical pump connected to the electrical circuit and activated by a switch member disposed on the support base of the dryer.
Claim 8
Dependent Claim
29 words
A hair dryer as described in claim 1, the support base provided with a surrounding flange at its free end, to provide greater stability to the dryer at rest.
Claim 9
Dependent Claim
31 words
A hair dryer as described in claim 1, the frontal area of the housing being flared to define a substantially rectangular discharge aperture having its wider area on an horizontal plane.
