[0001] The invention concerns a method for the steam treatment of scalp hair in accordance
with the preamble of Claim 1, as well as a device for the steam treatment of scalp
hair in accordance with the preamble of Claim 2.
[0002] Owing to the positive results obtained, steam treatment of scalp hair is usually
carried out with the aid of a device (steam apparatus) during hair color applications
in hair dressing salons. Suchlike devices are known in different embodiments from,
for example,
WO2005/001337A1 (Fig. 7). In such a device steam is blown through a spray into a steam hood in which
is positioned the head of a person (hairdresser's client) to whose scalp hair a hair
color has been applied. Ammonia is released through the chemical process and the heat
action of the steam. Since new steam is constantly generated, the ammonia is carried
out of the steam hood with the steam and right up to the eyes and nose of the person
and can cause irritation there. In addition an odor nuisance can occur as a result.
The publication
KR20050022743 shows a hair processing device with a suction unit to suck odor of permanent solution.
The task of the invention is to prevent by simple means this irritation and/or odor
nuisance during a corresponding steam treatment of scalp hair.
[0003] The task was solved according to the features of, respectively, Claim 1 or 2.
Further embodiments of the invention follow from the respective subclaims.
[0004] The invention is more closely illustrated by means of several embodiment examples.

[0005] The principle solution of the set task is to extract the steam 11 enriched with ammonia
C at the front region 12 of the steam hood 4. This is preferably carried out by means
of an electrically driven fan 10. This fan 10 is preferably attached directly at the
front region 12 of the steam hood 4. A suction port 13 of the fan 10 is so designed
in such a way that the extraction of the steam 11 takes place mainly in the region
above the eyes 14. Since ammonia emission C is reduced to such an extent during the
course of the steam treatment that no irritation or odor nuisance can occur, from
this time point on the fan 10 is deactivated at a preset ammonia emission value V
1.
[0006] The fan 10 can also be seated within the device 3.2 in order, for example, to support
the output of the steam 11. In this case the suction port 13 is passed through the
steam hood 4 into the neighborhood of the eyes 14.
[0007] The amount of air D that is to be extracted is controlled by the use of the electric
fan 10. This control can take place during a (preset) time ta, or through an ammonia
sensor 7 located in the extracted air 16 with which the concentration of the ammonia
emission C is measured and the fan 10 correspondingly regulated.
[0008] Since the concentration of the ammonia emission C in the air changes during the treatment
the correct amount of air 16 can always be extracted with a controlled fan 10 in order
to avoid irritation of the eyes 14. On the other hand, only the amount of air 16 that
is absolutely necessary is extracted. In this way a uniform dampness of the scalp
hair 1 is attained and a very consistent color reaction on the scalp hair 1 is achieved.
[0009] Fig. 1 shows a flow diagram of a method for the steam treatment of scalp hair 1 of
a person 2 with a device 3.2 with a steam hood 4, wherein the scalp hair 1 is first
treated with an agent that contains ammonia. At the start to of a steam treatment
a controllable extraction unit 5 on the steam hood 4 is activated by a control unit
6, wherein during the further course of the steam treatment ammonia emissions C are
recorded by a sensor 7 that is attached inside the steam hood 4 and measured by a
measurement unit 8 (Vx1...Vx5). The measurement unit 8 is connected with the control
unit 6, wherein on attainment or undershooting of a preset ammonia emission value
Vx5=V1 the extraction unit 5 is deactivated automatically by the control unit 6. At
the end of the steam treatment tb the device 3.2 (Fig. 3) is switched off automatically.
[0010] Fig. 2 shows a side view of a device 3 of the prior art. It is clear from this that
the ammonia emissions C from the treated scalp hair 1 reach the eye/nose region B
of the person 2 and can lead to irritation and an odor nuisance.
[0011] Fig. 3 shows a side view of a second device 3.2 with an automatic switch-off mechanism
and a steam hood 4 for the steam treatment of scalp hair 1 of a person 2. A sensor
7 to record the ammonia emission values Vx1...Vxn is arranged inside the steam hood
4. The ammonia sensor 7 is connected with a measurement unit 8 for measurement of
the ammonia emission values Vx1...Vxn, wherein the measurement unit 8 is connected
with a control unit 6. The device 3.2 or, respectively, the steam hood 4 has an extraction
unit 5 that is controllable by the control unit 6 and extracts the ambient air in
the neighborhood of an (upper) forehead region A or an eye/nose region B of the person
2. At the start to of the steam treatment the extraction unit 5 is activated automatically
by the control unit 6. By convergence with or undershooting of a preset ammonia emission
value V 1 the extraction unit 5 is deactivated automatically. Preferably an electric
fan 10 that can be arranged neatly in or on the steam hood 4, is simple to operate
(in on/off function and fan performance), and is very cost-effective is used as extraction
unit 5.
[0012] The extraction unit 5 is arranged inside or outside the steam hood 4 in such a way
that extraction of the ambient air in the neighborhood of the forehead region A or
the eye/nose region B of the person 2 takes place, wherein the electric fan 10 is
arranged in the extraction unit 5.
[0013] An optoelectronic ammonia sensor in chip form, for example, can be used as sensor
7.
[0014] Fig. 4 shows a detailed aspect of the second device 3.2 according to Fig. 3 as a
sectional view.
[0015] Fig. 5 shows a block diagram of the device 3.2. in accordance with, respectively,
Fig. 3 or Fig. 1. At the start to of a steam treatment a controllable extraction unit
5 on the steam hood 4 is activated by a control unit 6, wherein during the further
course of the steam treatment ammonia emissions C are recorded by a sensor 7 arranged
inside the steam hood 4 and measured by a measurement unit 8 (Vx1...Vx5). The measurement
unit 8 is connected with the control unit 6, wherein on attainment or undershooting
of a preset ammonia emission value Vx5=V1 the extraction unit 5 is deactivated automatically
by the control unit 6. At the end of the steam treatment tb the device 3.2 (Fig. 3)
is switched off automatically.
[0016] Fig. 6 shows a plan view of the device 3.2 according to Fig. 3. In particular, it
is evident here that the suction port 13 has approximately the width of the face of
the person 2.
[0017] Fig. 7 shows a perspective view of the device 3.1, 3.2 according to Fig. 3 with the
steam hood 4 removed. The steam sprays 18 are particularly evident here.
