Abstract

A hair dryer and steamer combination includes a handle housing mounting a fan blower producing a flow of air and a hair brush attachment having a hair engaging surface for seizing the hair to be styled. Included in the hair brush attachment is a heater which heats the water supplied from a water supplying tank at the end of the attachment to generate the steam. The attachment has its interior divided into an air flow chamber open rearwardly into the handle housing and a steam chamber accommodating the steam heater. The air flow chamber is provided with a number of air vents through which the air flow from the handle housing is discharged outwardly for drying the hair in engagement with the hair engaging surface. The steam chamber has a number of steam vents for discharging the steam outwardly for moistening the hair in engagement with the hair engaging surface. These air flow and steam chambers are separated from each other so that the steam generated within the steam chamber will not be directed to the air flow chamber and is only allowed to be discharged through the steam vents. The steam chamber and the hair engaging surface are defined commonly by a single member having good thermal conductivity so that the heat generated at the heater is transferred by conduction to the hair engaging surface for keeping it at a raised temperature, whereby effectively preventing the steam from being condensed on that surface.

Dependent claims

A hair dryer and steamer combination comprising:

a handle housing mounting therein a fan blower for producing a flow of air and formed at its front end with a discharge port for discharging the flow of air;
and
an elongated hair brush member having a hair engaging surface which extends in the lengthwise direction of said hair brush member for engagement with the hair strands to be styled and a steam generating device which comprises a water supplying means and an electric heater for heating the water supplied from said water supplying means to generate the steam;
said water supplying means including a tank and a plug with a moisturizing pad extending from within the tank for transferring water to the electric heater;
said hair brush member connected at its rear end to the front end of said handle housing so as to receive therefrom the flow of air;
said hair brush member being in the form of a hollow tube having an air flow chamber and a steam chamber which are elongated respectively in the lengthwise direction of said hair brush member and separated from each other;
said steam chamber is defined by a pipe which is open to a front end of said hair brush member for detachably receiving said plug;
said pipe having its inner wall sealed at its front end to said plug and at its rear end to said electric heater so as to define between the front and rear sealed portions a space within the length of which the electric heater is in contact with said moisturizing pad for generating the steam;
said air flow chamber being open to said discharge port of the handle housing and provided with a number of air vents which are open to said hair engaging surface for discharging therefrom the flow of air for drying the hair in engagement with said hair engaging surface;
said steam chamber being closed to said discharge port and accommodating therein said electric heater, said steam chamber having a portion forming the part of said hair engaging surface and provided in that portion with a number of steam vents for discharging the steam generated at said heater to the hair in engagement with said hair engaging surface;
and
said steam chamber and said hair engaging surface being commonly defined by a single member having good thermal conductivity.
