FIG. 8
is a diagram illustrating the pipe arrangement in the cabinet of the prior art hair washer. In the figure, the same reference numerals and characters as those in
FIGS. 6 and 7
designate the same or corresponding parts. In addition, reference numeral
11
designates a mixing tank for mixing water and hot water which is transmitted from an external water supply and an external hot water supply, via a curb stop, a strainer, and a check valve (not shown), to prepare wash water having a temperature suitable for hair washing. Numeral

13
. Numeral
17
designates a valve for a hand shower. Character A designates a hot water supply way, one end of which is connected to the hot water supplying pump
16
, the other end of which has some branches connected to the shower heads S
1
to S
11
and the nozzle heads N
1
to N
6
at top parts thereof. Numeral
18
designates a draining electromagnetic valve provided midway of the hot water supply way A to drain unnecessary wash water. Characters
19
a
to
19
k
designate hot water supplying electromagnetic valves for supplying the wash water to the shower heads S
1
to S
11
and nozzle heads N
1
to N
6
by an opening and closing of the supply of wash water via a closing operation. Numeral
20
designates a shampoo supplying pump for pumping out the shampoo agent from the shampoo tank
6
. Numeral
21
designates a conditioner supplying pump for pumping out the conditioner agent from the conditioner tank
7
. Numerals
22
and
23

23
.
Hereinafter, an explanation will be given of the operation of a hair washer constructed as described above with reference to
FIGS. 6
to
8
.
At first, when the hair washer is started, hot water and water are supplied to the mixing tank
11
from an external water supply and an external hot water supply, via the curb stop, the strainer, and the check valve. The hot water and the water are mixed by the mixing tank
11
to prepare the hot water having a temperature suitable for hair washing, which is provided to the hot water storing tank
13
via the motor valve
12
.
At the time when predetermined amounts of hot water are stored in the hot water storing tank
13
, stand-by mode follows. During the mode, after the person under hair washing inserts his head to the opening
2
a
of the cistern
2
while lying on his back and putting his head on the neck receiving part
3
a
, the face cover
4
is closed.
Next, when the hot water supplying electromagnetic valves
19
a
to
19
k
are opened, the hot water stored in the hot water storing tank
13
is simultaneously sucked up by the hot water supplying pump
16
, to be provided to the hot water supply way A, whereby cold water stored in the hot water supply way A during an initial predetermined period is drained out from the shower heads S
1
to S
11
and the nozzle heads N
1
to N
6
.
Next, when all the cold water stored in the hot water supply way A is drained out, the hot water supplying electromagnetic valve
19
k
is closed, in order to stop supplying hot water to the nozzle heads N
1
to N
6
, thereby allowing hair washing to be performed utilizing the hot water spouted from the shower heads S
1
to S
11
during a predetermined period.
Next, a shampooing process is followed. When the hot water supplying electromagnetic valve
19
k
is opened, shampoo agent stored in the shampoo tank
6
is simultaneously sucked up by the shampoo supplying pump
20
via the shampoo agent supply way B
1
, and provided to the hot water supply way A via the check valve
22
. The shampoo agent is mixed with the hot water of the hot water supply way A, thereby preparing mixed water with shampoo agent. The mixed water with the shampoo agent is spouted from the nozzle heads N
1
to N
6
, to perform hair washing with shampoo agent with hot water spouted from the shower heads S
1
to S
11
.
Next, when the shampooing process completed completed, the hot water supplying electromagnetic valve
19
k
is closed, to stop the spouting of the water mixed with shampoo agent from the nozzle heads N
1
to N
6
, thereby performing a first rinsing of hair for washing away shampoo agent attached to the hair.
Next, a conditioning process is followed. When the hot water supplying electromagnetic valve
19
k
is opened, conditioner agent stored in the conditioner tank
7
is simultaneously sucked up by the conditioner supplying pump
21
via the conditioner agent supply way B
2
, in order to be provided to the hot water s
