  Next, an explanation will be given of the operation of washing hair with normal water using the time chart of FIG. 3. Since the solenoid valve 19 connected to the bypass 18 is in a normally open state, it is installed in a hair washing device. When the stop cock 5 is opened to a desired flow rate (a), water (hot water) corresponding to the opening of the stop cock 5 passes through the bypass 18 and the check valve 12 through the shower. And the hair can be washed with ordinary water (hot water) (b).

  Next, the use of carbonated water in which the practitioner performs hair washing in which the concentration of carbonated water is set in accordance with the hair and scalp of the patient will be described with reference to FIG. 4. First, the stop cock 5 is closed. It is in a state. In this state, a carbonated water switch for selecting whether to wash the hair with carbonated water installed on the operation panel and normal water (hot water) is operated to turn it on (c). In this state, the carbonated water indicator lamp that is energized when carbonated water provided near the carbonated water switch is selected is turned on (d).

  In this state, the practitioner operates a flow rate switch for setting the flow rate of water (hot water) installed on the operation panel (e). The flow rate setting by this flow switch is, for example, 4 steps. When the practitioner selects the 4th step (the highest flow rate), the 4th step flow indicator lamp provided near the flow switch is displayed. Illuminated (f). Here, when the carbonate switch is operated, carbonated water having the lowest flow rate is selected, and the first stage of the flow rate indicator lamp is lit. Therefore, to set the fourth stage, the flow switch is operated three times. . The flow rate setting is not limited to four stages.

  Next, the operator operates a concentration switch for setting the concentration of the carbonated water generated (g). The concentration setting of carbonated water by this concentration switch is, for example, three levels. When the practitioner selects the third level (the highest density), the third level provided near the concentration switch. The concentration indicator is turned on (h). Here, when the carbonated water switch is operated, carbonated water having the lowest concentration is selected, and the first stage of the concentration indicator lamp is lit, so that the third stage is operated twice. The density setting is not limited to three levels. Next, the hair washing time is set by operating a timer installed on the operation panel.

  Next, when the stop cock 5 is fully opened (a), water (hot water) flows from the water (hot water) supply source 4 to the flow sensor 6, so that the detection output of water (hot water) from the flow sensor 6 is obtained. Is sent to the control board 3, and the output is sent from the control board 3 to the solenoid valves 8 to 10 and the cascade pump 11 so as to obtain the set concentration and flow rate (J) and simultaneously to the solenoid valve 19 of the bypass 18. (1) and the time start output of the timer are sent.

  At the same time as the cascade pump 11 starts rotating, carbon dioxide gas is supplied from the combination of the orifices 8a, 9a, and 10a selected and opened. The carbonated water having the flow rate and concentration of water (hot water) set by is supplied to the shower head from the discharge port, and hair washing with carbonated water can be performed (b).

  In this hair washing, when the set time by the timer is reached, the operation is stopped because the control board 3 cuts off the energization of the cascade pump 11 and the solenoid valves 8 to 10. Is stopped but water (hot water) flows for a short time since the stop cock 5 is open.

  Then, after the energization of the cascade pump 11 is cut off, the practitioner closes the water stop cock 5. Further, energization to the solenoid valve 19 of the bypass passage 18 stops after a certain time after the operation of the cascade pump 11 is stopped, and the bypass passage 18 is opened. Therefore, when the hair washing with water (hot water) is desired, the stop cock 5 is opened. This makes it possible to perform normal hair washing.

  Next, the flow rate and concentration of water (hot water) are determined in advance, for example, a mode used for perms, hair dyes, etc., and the flow rate indicator lamp with 4 levels of flow rate on the operation panel is the second level from the top, 3 In the design mode in which the density indicator of the stage is set to the third stage from the top, or in the mode in which the hair is washed in the middle of the permanent, the flow rate indicator on the operation panel is the fourth stage from the top, and the density indicator in the third stage The operation of washing the hair by operating the one-touch switch installed on the operation panel for selecting the intermediate water washing mode set at the third level from the top will be described with reference to FIG. The mode is not limited to the above two examples.

  Operate the one-touch switch of the mode in which the one-touch switch of the one-touch mode is desired (i). Since the amount of water (hot water) and the amount of carbon dioxide gas set by operating the one-touch switch are stored in the control board 3, they are set by a command from the control board 3 without operating the flow switch. Therefore, only the flow rate indicator lamp of the set flow rate is turned on (f).

  Further, since the concentration is also stored in the control board 3, it is set by a command from the control board 3 without operating the concentration switch, so that only the concentration indicator lamp of the set flow rate is turned on (h ). The amount of carbon dioxide gas controlled by the control board 3 is automatically performed by the combination of the orifices 8a to 10a (k) as described with reference to FIG. Further, the discharge time of carbonated water by the timer is also stored in the control board 3, and the carbonated water indicator lamp is turned on.

  Next, when the stop cock 5 is fully opened (a), water (hot water) flows from the water (hot water) supply source 4 to the flow sensor 6, so that the detection output of water (hot water) from the flow sensor 6 is obtained. Is sent to the control board 3, and output is sent from the control board 3 to the solenoid valves 8 to 10 and the cascade pump 11 so as to obtain the set concentration and flow rate (J) and simultaneously to the solenoid valve 19 of the bypass 18. A closing output is sent (l) and the time start output of the timer is sent.

  The operation after the cascade pump 11 starts rotating is the same as the operation when using the carbonated water in which the practitioner in FIG. 4 sets the amount and concentration of water (hot water). However, since only the operation is performed according to the amount of water (hot water) and the amount of carbon dioxide gas stored in the control board 3 in advance, the description of the subsequent operation is omitted.

  Next, to the one carbonated water discharge device X, two hair washing devices A and B are connected, the hair washing device A discharges carbonated water, and the hair washing device B discharges water (hot water).

Accordingly, when the carbonated water discharge device X is operated to discharge carbonated water, carbonated water flows in the shower of the hair washing apparatus A, so that the hair can be washed with carbonated water.

  On the other hand, since water (hot water) from the water (hot water) supply source 4 is discharged to the switching valve 22 of the hair washing device B through the stop cock 5, water (hot water) from the switching valve 22 is switched to the switching valve. Since water (hot water) flows into the shower of the hair washing apparatus B through the hot water 23, normal hair washing with water (hot water) can be performed.

  When performing an operation of discharging carbonated water from the hair washing apparatus B, the switching valves 20 to 23 are interlocked and switched as shown in FIG. The switching valve 23 discharges carbonated water from the carbonated water discharge port of the carbonated water discharge device X to the shower, and the switch valve 22 discharges water (hot water) from the water (hot water) supply source 4 to the carbonated water discharge device. Discharge to X inlet side. Therefore, if carbonated water is discharged by operating the carbonated water discharge device X, carbonated water flows through the shower of the hair washing apparatus B, so that the hair can be washed with carbonated water.
