FIELD OF THE INVENTION
The present invention relates to a hair washer which is established in a beauty salon, a barber's shop or the like, and more particularly to washing nozzles.
BACKGROUND OF THE INVENTION
FIGS. 2 and 3
are diagrams schematically illustrating the construction of a prior art hair washer.
FIG. 2
is a plan view and
FIG. 3
is a longitudinal sectional view.
In the figures, reference numeral
11
designates a cabinet. Numeral
12
designates a cistern provided within the cabinet
11
, into which a person under hair washing
15
inserts his head. Numeral
13
designates a neck receiving part for supporting the nape part of the person under hair washing
15
when the person inserts his head into the cistern
12
. Numeral

12
. Hair washing is performed using hot water spouted from the shower heads S
1
to S
12
and hot water mixed with the shampoo agent or the conditioner agent spouted from the mist heads M
1
to M
6
. A series of hair washing processes are completed by the following processes: preliminary washing, a shampooing process, a rinsing process, a conditioning process, and a rinsing process. The shower heads S
1
to S
12
and the mist heads M
1
to M
6
automatically spout hot water or the like during a predetermined period in accordance with the respective processes of hair washing via control from a control device (not shown).
In addition, the spouting directions of the shower heads S and the respective mist heads M are set such that the shower heads S
1
and S
12
, and the mist head M
1
spout hot water or the like to the top of the head, shower heads S
2
to S
5
and mist heads M
2
and M
6
spout the same to the sides of the head, and shower heads S
7
to S
10
spout the same to the nape part, whereby washing is performed.
FIGS. 4
illustrate the construction of the washing nozzles of a prior art washing apparatus. FIG.
4
(
a
) is a longitudinal cross sectional view illustrating the construction of a mist head M. FIG.
4
(
b
) is a longitudinal cross sectional view illustrating the construction of a shower head S.
In
FIG. 4
, the same reference numerals and characters as those in
FIGS. 2 and 3
designate the same or corresponding parts.
As shown in FIG.
4
(
a
), in a mist head M, a mist nozzle
20
is connected to a washing water supply pipe
5
by a coupler
50
.
The washing water supply pipe
5
leads hot water which is pumped out from a hot water storing tank (not shown) within the cabinet
11
and hot water mixed with shampoo agent or conditioner agent obtained by mixing hot water with shampoo agent or conditioner agent which is pumped out from a shampoo tank or a conditioner tank (not shown), to supply the same to the mist nozzle
20
.
The coupler
50
is provided so as to pass through a wall part of the cistern
12
, one end of which is connected to the washing water supply pipe
5
, while the other end of which is connected to the mist nozzle
20
.
The mist nozzle
20
is provided with a single spouting orifice
20
a
on an upper part thereof, thereby spouting like a mist the hot water mixed with the shampoo agent or the conditioner agent which is supplied from the washing water supply pipe
5
via the coupler
50
.
As shown in FIG.
4
(
b
), in the shower head S, the shower nozzle
30
is connected to the hot water supply pipe
6
by a coupler
60
.
The hot water supply pipe
6
leads hot water which is pumped out from the hot water storing tank within the cabinet
11
, to supply the same to the shower nozzle
30
.
The coupler
60
is provided so as to pass through a wall part of the cistern
12
, one end of which is connected to the hot water supply pipe
6
, while the other end of which is connected to the shower nozzle
30
.
The shower nozzle
30
is provided with a plurality of spouting orifices on an upper part thereof, thereby spouting like a shower the hot water which is supplied from the hot water supply pipe
6
via the coupler
60
.
Hereinafter, an explanation will be given of a method for performing hair washing to a person whose hair is to be washed using a hair washer constituted as described above.
The operation of hair washing is started when a person whose hair is to be washed lies on his back while putting his nape on the neck receiving part
13
, and inserting his head into the cistern
12
.
First, hot water is spouted from the shower heads S
1
to S
12
, to perform hair washing during a predetermined period.
Next, a shampooing process follows, and hot water is spouted from the shower heads S
1
to S
12
as well as hot water mixed with shampoo agent is spouted from the mist heads M
1
to M
6
, to perform hair washing with shampoo.
Next, a rinsing process follows, and spouting of the hot water mixed with shampoo agent from the mist heads M
1
to M
6
is stopped, to perform hair washing using hot water spouted from the shower heads S
1
to S
12
.
Next, a conditioning process follows, hot water is spouted from the shower heads S
1
to S
12
as well as hot water mixed with conditioner agent is spouted from the mist heads M
1
to M
6
, to perform hair washing with rinse.
Next, a rinsing process follows, and spouting of the hot water mixed with conditioner agent from the mist heads M
1
to M
6
is stopped, to perform hair washing using hot water spouted from the shower heads S
1
to S
12
. Then a series of washing process ends.
However, in the prior art hair washer, washing nozzles are fixed disposed. Therefore the spouting range of hot water or the like from the washing nozzles is kept constant and the spouting range is concentrated in the center of the cistern.
Therefore, when the hair style of a person under hair washing is short, it is possible to wash all of his hair within the spouting range of the washing nozzles, whereas when the hair style of a person under hair washing is long, there arises problem that hot water or the like from the washing nozzles does not spread over some parts if the hair which are out of the spouting range of the washing nozzles, for example, tip parts of his hair, or the like, whereby there arise a problem such that hair washing is complete.
In addition, even when only one part of the head needs to be washed concentratedly, in the case where a permanent wave or hair coloring is performed, or hair is partly dirty, or the like, the spouting range from the washing nozzles is kept constant. Accordingly, hot water or the like is spouted to some parts where washing is not required to be performed, thereby being uneconomical and inefficient.
SUMMARY OF THE INVENTION
To solve the above problems, it is an object of the present invention to provide a hair washer which enables partial hair washing, and which can wash hair in a condition most suitable for hair style and figure of the person undergoing hair washing.
Other objects and advantages of the present invention will become apparent from the detailed description, and the specific embodiments described are provided only for illustration since various additions and modifications within the spirit and scope of the invention will be apparent to those of skill in the art from the detailed description.
According to a first aspect of the present invention, a hair washer having a cistern, to which a person under hair washing enables to insert his head and a liquid spouting means for spouting liquid supplied from a supply pipe, which is provided on an inner wall of the cistern, wherein the liquid spouting means comprises a nozzle for spouting liquid, a coupler for connecting the nozzle to the supply pipe, and a nozzle holding means for fixing the nozzle and the coupler on inner walls of the cistern, the nozzle has an approximately spherical-shaped base part, the
