Abstract

Abstract An apparatus for applying a mixture of air and vapor to the face or hair includes an evaporator comprising a closed tank partially filled with water to leave a residual space thereabove and provided with an electric heater immersed in the water for generating a steam which fills the residual space. A first downwardly sloping tube connects the an attachment, located higher than the tank and adapted to fit on the head or face to be treated, to the residual space. A upwardly sloping second tube connects the outlet of a fan positioned lower than the tank to the residual space. Both the temperature and the flow of the vapor-air mixture can be varied by changing not only the power of the electric heater but also the rotational speed of the fan.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 194 words
A hairdressing apparatus comprising: a fan means having an inhaling entrance and an exhaling exit for inhaling relatively cool dry external air through said inhaling entrance and blowing said cool dry external air from said exhaling exit; an attachment which can be fitted upon some portion of the body of a person in hairdressing or beauty treatment; a communicating passage which connects the attachment with the exhaling exit of the fan and has an exhaust opening in the attachment; and an evaporator mounted in an intermediate portion of the communicating passage and positioned substantially lower than the exhaust opening but substantially higher than the exhaling exit of the fan, said evaporator including a closed-type tank for partially containing water so that a residual space is left above the water and an electric heater means mounted for heating said water; said communicating passage being composed of a first communicating tube which connects the attachment with the residual space in the closed-type tank and which slopes downwardly toward the residual space and a second communicating tube which connects the residual space with the exhaling exit of the fan and which slopes upwardly toward the residual space.
Claim 2
Dependent Claim 194 words
A hairdressing apparatus comprising: a fan means having an inhaling entrance and an exhaling exit for inhaling relatively cool dry external air through said inhaling entrance and blowing said cool dry external air from said exhaling exit; an attachment which can be fitted upon some portion of the body of a person in hairdressing or beauty treatment; a communicating passage which connects the attachment with the exhaling exit of the fan and has an exhaust opening in the attachment; and an evaporator mounted in an intermediate portion of the communicating passage and positioned substantially lower than the exhaust opening but substantially higher than the exhaling exit of the fan, said evaporator including a closed-type tank for partially containing water so that a residual space is left above the water and an electric heater means mounted for heating said water; said communicating passage being composed of a first communicating tube which connects the attachment with the residual space in the closed-type tank and which slopes downwardly toward the residual space and a second communicating tube which connects the residual space with the exhaling exit of the fan and which slopes upwardly toward the residual space.
Claim 3
Dependent Claim 16 words
A hairdressing apparatus as in claim 1 wherein the speed of the fan means is adjustable.
Claim 4
Dependent Claim 21 words
A hairdressing apparatus as in claim 1 wherein said electric heater means is an immersion type heater immersed in said water.
