DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to appliances for drying the hair.
PRIOR ART
Previously known appliances generally consist in drying hair by blowing air that is heated by means of a heater resistance.
Such appliances are often associated with removable accessories that are fixed to the blowing end of the appliance. These accessories make it possible to dry hair while preparing it for a particular type of hair dressing, for example waving it, giving it volume, etc.
The accessories often have hair dressing elements such as fingers or stiff bristles which come into contact with locks of wet hair and facilitate combing and separating stuck-together wet hair.
Nevertheless, the effectiveness of the drying operation depends to a large extent on the skill of the user in handling the appliance provided with the accessory, in particular when drying hair quickly over its entire length or when giving hair the desired amount of volume. In addition, the operation of drying and dressing one's own hair is more difficult because of the discomfort of the position of the arms.
That is why the present invention seeks to mitigate these drawbacks by proposing an appliance that facilitates and accelerates the drying of hair and that gives volume thereto without requiring any particular action from the user.
The invention thus seeks to provide an accessory secured to the blowing end of an appliance for drying hair, the accessory being organized to pass the air expelled from the appliance for drying hair, and including elements designed to come into contact with the hair such as fingers or stiff bristles.
SUMMARY OF THE INVENTION
According to the invention, this accessory is characterized in that it includes vibrator means for putting said elements into vibration while drying hair.
The term "vibrator means" is used to cover means that impart cyclical motion to the elements. For example, this may be vibration of very small amplitude, of the order of the thickness of the elements, or of amplitude equal to several times said thickness. In addition, the frequency of the vibration may vary over a wide range, e.g. being visible or invisible to the naked eye.
This vibratory motion of the fingers or of the stiff bristles facilitates penetration thereof into the hair and promotes unsticking of hair that is still wet. It increases the area of exchange between the air and the hair, particularly close to the roots, thereby facilitating and accelerating drying, giving rise to a natural bouffant hairstyle without special action by the user.
In addition, the drying appliance can be held so as to put the elements of the accessory into contact with the scalp by selecting blown air of an appropriate temperature. Under such circumstances, the vibration of the elements is imparted to the scalp, thereby massaging it.
The accessory may be removable or non-removable.
In an advantageous version of the invention, the vibrator means comprise a part mounted to rotate on a shaft secured to a wall carrying the elements, the shaft passing through points of the part other than its center of gravity, means being provided for setting the part into rotation about the axis of the shaft.
The part is thus mounted on an shaft so as to be unbalanced. During rotation of the part, this unbalance generates vibration of the wall supporting the shaft, which vibration is transmitted to the above-mentioned elements. The means for setting the part into rotation may be internal to the accessory or to the appliance and they may be of various kinds.
In a preferred version of the invention, the part is a fan free to rotate about the axis of the shaft and lying, at least in part, in the flow path of the blown air so as to be set into rotation thereby.
This version makes it possible to avoid providing the appliance or the accessory with special means for setting the part into rotation. In addition, the elements are put into vibration during stages when the heating appliance is in operation.
The invention also provides a hair dryer appliance characterized in that it incl
