Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic hair washing machine mainly for business use, which is used in barber shops, beauty salons and the like.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Examined Patent Publication No. 52-1124
There is known an automatic hair washing machine as shown in Japanese Patent Publication No. 8 which sprays warm water for washing on the head and hair without washing hands to wash the hair. In such an automatic hair washer, for example, washing water stored in a hot water storage tank is pumped out by a pump and supplied to a nozzle for jetting washing water. And
At the time of washing hair, washing water of a certain strength is jetted from the nozzle to wash the head and hair.

[0003]

When the hair is washed by the above-mentioned conventional automatic hair washer, many of the people to be washed feel unsatisfactory, and there is no stimulation or massage effect on the scalp. Usually, when washing hair manually, the scalp of the person to be washed is appropriately stimulated with a fingertip and massaged. Therefore, when washing hair with an automatic hair washing machine, there is a demand for an automatic hair washing machine that not only cleans the hair simply but also gives a massage effect to the scalp similar to the case of manually washing the hair.

Therefore, the present applicant has filed Japanese Patent Application No. 4-4493.
In No. 3, etc., an upper nozzle link, which is swingably supported at an upper position in the water tank and in which a plurality of nozzles for spraying washing water to the head of the person to be washed are arranged, and an upper nozzle link in the water tank. A lower nozzle link that is rotatably supported below the nozzle link and that has a plurality of nozzles for spraying washing water on the neckline of the person to be washed. We proposed an automatic hair washing machine that changes the pressure or flow rate of the washing water supplied to the machine in a predetermined pattern to increase or decrease the strength of the washing water sprayed from above and below.

In this automatic hair washing machine, the strength of the washing water sprayed from above and below gives a proper stimulus to the scalp of the person to be washed and produces a massage effect. By the way, even if the hair has almost the same length, for example, so-called short hair,
Hairstyles vary depending on the person being washed, such as so-called curly hair, straight hair, permanent hair, and the like. The amount of hair also varies depending on the person being washed. Thus, when washing hair manually, it naturally copes with the difference in the type of hairstyle and the difference in the amount of hair. Therefore, even when washing hair with an automatic hair washing machine, it is desired to change the content of the hair washing operation according to the difference in the type of hairstyle and the like.

However, in the above automatic hair washing machine, since the hair-washing operation time is constant regardless of the type of hairstyle, it is impossible to select a wide hair-washing course according to the type of hairstyle. Therefore, depending on the person being washed, the cleaning effect,
There was a risk that the feeling of massage would be unsatisfactory. In addition, the following may be considered as other factors that make the person to be washed feel unsatisfactory in the cleaning effect and the feeling of massage. That is, in the above automatic hair washing machine, while oscillating the upper and lower nozzle links, the cleaning water is sprayed only from the nozzles of the lower nozzle link for a certain period, and the cleaning water is simultaneously sprayed from each nozzle of the upper and lower nozzle links for a certain period. The washing is given to give the person to be washed a feeling of massage. As a result, it is thought that as the washing process progresses, the person to be washed will be able to predict to some extent from which direction the washing water will be jetted, and become accustomed to the stimulation of the scalp by the jetting force. To be

In view of the above, the present invention enables a wide range of hair washing operation contents to be selected according to the type of hairstyle and the amount of hair of the person to be washed. While the cleaning is in progress, the direction in which the cleaning water is sprayed is changed to make it difficult for the person to be washed to predict from which direction the cleaning water will be sprayed. Accordingly, it is an object of the present invention to provide an automatic hair washer capable of increasing the cleaning effect and the feeling of massage to the person to be washed.

[0008]

The means for solving the problem according to claim 1 of the present invention is a washing means for washing the hair of a person to be washed by spraying washing water, and an input for inputting a start signal of a washing operation. Means, a storage means for storing a plurality of washing courses in which the content of the hair washing operation is changed according to the type of hair style and the amount of hair of the person to be washed, and a signal for starting the hair washing operation from the input means. In accordance with the input of, a predetermined washing course is selected from the washing courses stored in the storage means, and within a predetermined time after the hair washing operation start signal is input, the input of the hair washing operation start signal from the input means is performed again. Based on the cleaning course selected by the course changing means, the cleaning course to be selected is sequentially selected and changed from the cleaning courses stored in the storage means. Shampoo It is intended to include a drive control means for controlling the drive.

According to a second aspect of the present invention, there is provided an upper nozzle, which is swingably supported at an upper position in a water tank and has a plurality of nozzles for spraying washing water onto the head of a person to be washed. A link, a lower nozzle link that is rotatably supported at a position lower than the upper nozzle link in the water tank, and has a plurality of nozzles arranged to inject wash water to the neckline of the person to be washed, First jetting means for jetting washing water from each nozzle arranged in the upper nozzle link, and second jetting means for jetting washing water from each nozzle arranged in the lower nozzle link And a switching means that alternately drives the first spraying means and the second spraying means so that the wash water is sprayed alternately from the vertical direction at a predetermined time in the hair washing operation. .

[0010]

In the problem solving means according to claim 1, when the hair washing operation start signal is input again from the input means within a predetermined time after the hair washing operation start signal is input, the course changing means selects the washing course to be selected. , The cleaning courses stored in the storage means are sequentially selected and changed. Then, the drive control means controls the drive of the hair washing means based on the washing course selected by the course changing means.

As described above, since the content of the hair washing operation can be widely selected according to the type of hairstyle and the amount of hair of the person to be washed, the washing effect and the feeling of massage to the person to be washed can be increased. In the problem solving means according to claim 2, the switching means alternates the first jetting means and the second jetting means so that the wash water is jetted alternately from the vertical direction at a predetermined time in the hair washing operation. Switch to drive.

Therefore, it is possible to make it difficult to predict from which direction the washing water will be jetted to the person to be washed, by changing the jetting direction of the washing water during the washing process. Therefore, the washing effect and the feeling of massage to the person to be washed can be increased.

FIG. 4 is a front view showing the detailed structure of the upper nozzle link. With reference to FIG. 4, the upper nozzle link 55
The detailed configuration of will be described. Upper nozzle link 55
Includes a water pipe 551 having a substantially semi-arcuate shape formed along the head inserted when washing hair, and a support means 552 for supporting one end of the water pipe 551 on the side wall 511 of the water tank.

A plurality of nozzles 57 are arranged in the water pipe 551 at predetermined intervals. The support means 552 is a water pipe 55.
Axial pipe 5 connected to one end of 1 by a connecting member 553
54. The shaft pipe 554 penetrates the side wall 511 of the water tank and projects to the outside of the side wall 511. Further, the circumference of the shaft pipe 554 is surrounded by a housing 555 fixed to the side wall 511 of the water tank, and between the housing 555 and the shaft pipe 554,
A bearing 556 is fitted so that the shaft pipe 554 is rotatably held with respect to the housing 555.

A rotary joint 557 is connected to the outer end of the shaft pipe 554. A cleaning water supply pipe (not shown) is connected to the rotary joint 557, and the cleaning water is supplied to the water pipe 551 through the rotary joint 557, the shaft pipe 554 and the connecting member 553. Therefore, the cleaning water supplied to the water pipe 551 is jetted toward the head from the plurality of nozzles 57 arranged in the water pipe 551.

In this way, the water pipe 5 of the upper nozzle link 55
When only one end of 51 is held on the side wall 511 of the water tank and the other end of the water pipe 551 is in a free state, that is, a so-called cantilever support structure is provided, so that assembly work at the time of manufacturing is improved. This is because when both ends of the water pipe 551 are rotatably attached to both sides of the side wall of the water tank, the central axis lines of the both side holding portions must be aligned, and when the attachment hole is formed in the side wall, it must be performed accurately. . In addition, since the holding members on both sides are required, the number of parts is large and the assembly takes time. On the other hand, if the above-mentioned cantilever support is used, a holding member on only one side is sufficient, and there is no need to align the center axis, so that the workability during assembly is improved.

However, depending on the model, the upper nozzle link 55 does not necessarily have to have a cantilever support structure. For example, Japanese Patent Publication No.
As described in JP-A-2-31791, it is possible to use a so-called double-supported head-top nozzle link in which both ends of the water pipe 551 are rotatably supported by the side walls of the water tank.

A rotary joint 584 is connected to the tip of the root of the water pipe 581. A washing water supply pipe (not shown) is connected to the rotary joint 584, and washing water can be supplied to the water pipe 581 through the rotary joint 584. Therefore, the water pipe 581
The washing water supplied to the nozzle is sprayed toward the neckline portion from the plurality of nozzles 59 arranged in the water pipe 581.

At the base of the water pipe 581, the pulley 5
85 is fixed. A protrusion shaft 586 is formed on the pulley 585 at a position eccentric from the center of rotation. Then, as will be described later, when the driving force is applied to the protruding shaft 586, the pulley 585 rotates, and the water pipe 581 rotates accordingly. As a result, the ejection directions of the plurality of nozzles 59 arranged in the water pipe 581 can be changed.

The lower nozzle link 58 may also have a so-called double-support structure depending on the circumstances. FIG. 6 is a diagram schematically showing a drive mechanism for driving the upper nozzle link and the lower nozzle link. A drive mechanism for driving the upper nozzle link 55 and the lower nozzle link 58 will be described with reference to FIG.

Warm water is jetted from the nozzle of the type. On the other hand, when the drain valve 98 is open, the upper nozzle valve 96A, the lower nozzle valve 96B and the long valve 97 are closed, and the hot water sucked by the pump 95 is drained from the drain pipe 91.

The above three types of nozzles 57, 59 and 60
The washing water sprayed from is received in the water tank 51,
The water is drained to the drain pipe 91 through the drain trap 99 arranged at the drain port of the water tank 51. The drain trap 99 has a conventionally known structure, and is for preventing the generation of a foul odor in the water tank 51 and for preventing the hair dropped in the water tank 51 from flowing out to the drain pipe 91.

A branch pipe 100 connected to the shampoo storage box 11 and a branch pipe 101 connected to the treatment storage box 12 are connected to the outflow pipe 96. Branch 100
A shampoo valve 102 and an amount adjusting valve 103 are provided in the middle of the above, and a treatment valve 104 and an amount adjusting valve 105 are provided in the middle of the branch pipe 101. Therefore, when the shampoo valve 102 is opened during the operation of the pump 95, the branch pipe 10 is
0 becomes negative pressure, the shampoo liquid stored in the shampoo storage box 11 flows into the outflow pipe 96 from the branch pipe 100,
The shampoo liquid is mixed in the hot water taken out from the hot water storage tank 87. Similarly, when the treatment valve 104 is opened during the operation of the pump 95, the branch pipe 101 has a negative pressure, and the treatment liquid stored in the treatment storage box 12 is mixed into the warm water flowing through the branch pipe 101.

Therefore, by operating the shampoo valve 102 or the treatment valve 104 and adjusting the amount adjusting valve 103 or 105, the shampoo liquid or treatment is injected into the washing water sprayed from the three kinds of nozzles 57, 59 and 60. Liquid can be mixed. The valves 85, 94, 96A, 96B, 9
Solenoid valves are used as 7, 98, 102 and 104.

Is a timing chart showing each stroke time in the cleaning course. An outline of the flow of the hair washing process during the hair washing operation will be described with reference to FIG. 9.

When the power is turned on, the standby mode is entered.
Thereafter, when the hot water supply key 21 is turned on, the hot water storage valve 85 is opened to enter the hot water supply mode, and then the standby mode is entered. Then, when the hair washing operation is started, FIG.
When the full course is selected by the washing course selection key 35 shown in, the hair washing mode corresponding to the hair washing course is entered, and initial drainage (continuous) → weak washing (continuous) → pre-washing (fir) → main washing (bottom only) → fir → continuous → spot → fir) →
Rinsing 1 (up and down → continuous → spot → fir tree) → treatment (continuous) → rinse 2 (continuous) is followed by washing. When the shampoo course is selected,
Enter the hair washing mode according to the hair washing course, initial drainage (continuous) → weak washing (continuous) → prewash (fir) → main wash (bottom only → fir → continuous → spot → fir) → rinse 1 (up and down →
Hair washing is completed after a sequence of continuous → spot → rubber → rinse 2 (continuous) (however, only when setting a long course). When the plain rinse course is selected, the hair washing mode according to the relevant hair washing course is entered, and initial drainage (continuous) → light wash (continuous) → rinse 1 (upper and lower → continuous → spot → chaff) → rinse 2 (continuous) (However, only when setting the long course) The hair washing is completed. The treatment course enters the hair washing mode according to the relevant hair washing course, and initial drainage (continuous) → weak washing (continuous) → rinse 1
(Upper / lower → Continuous → Spot → Momi) → Treatment (Continuous) → Rinse 2 (Continuous) When the long hair washing course is started, the long valve 97 is turned on and the washing water is jetted from the fixed nozzle 60 in the process after the "weak washing" shown by hatching in the figure.

The operating time corresponding to each of the above strokes is
As shown in FIG. 10, t1, t2, t3, t4t, t
5, t6, t7, t8, t9, ta, tb, tc, t
As indicated by d and te, it is set according to each cleaning course such as a full course, a shampoo course, a plain rinse course and a treatment course. Here, the hot water supply mode will be described in detail. In the hot water supply mode, first, the link motor 71 shown in FIG. 6 is normally rotated (referred to as “right rotation”) to swing the upper nozzle link 55 downward to move the first lead. When the switch MS1 detects the horizontal position of the upper nozzle link 55, the link motor 71 is stopped to stop the upper nozzle link 55 at the horizontal position (see * 9 in FIG. 9).

In this way, the upper nozzle link is stopped at the horizontal position when the head of the person to be washed is inserted into the water tank in the back position in the standby mode, especially when the hair is long, the hair is hung down at the bottom of the water tank. This is to prevent the upper nozzle link from getting in the way. When the water temperature detection result by the water temperature detection thermistor Th2 (see FIG. 7) shown in FIG. 7 indicates that the temperature of the hot water mixed by the mixing valve 84 is in the temperature range suitable for washing hair, the hot water storage valve 85 is turned on.
Then, hot water is stored in the hot water storage valve 85. On the other hand, when the water temperature detection result by the water temperature detection thermistor Th2 indicates that the temperature of the hot water mixed by the mixing valve 84 is outside the temperature range suitable for washing hair, the hot water storage valve 85 is turned off and the drain valve 94 is turned on. Hot water is drained to the outside through the drain pipe 93. As described above, in the hot water supply mode, if the hot water that has passed through the mixing valve 84 is in a temperature range that cannot be used for washing hair, the hot water in the tank 87 is not supplied to the hot water storage tank 87 but is drained to the outside. It stabilizes the temperature.

FIG. 11 is a flow chart showing the control contents relating to the setting of the hair washing contents of the washing course after the hair washing is started. The control flow at the start of hair washing will be described with reference to FIG. After the head of the person to be washed is inserted into the water tank, when the start key 31 is pressed in step S1, the short hair washing course or the long hair washing coat is automatically obtained based on the output of the hair length sensor in steps S2 to S4. Is set. That is, if the output of the hair length sensor is ON in step S2, it is determined in step S3 that the person to be washed is short hair, and the short hair washing course is set. On the other hand, if the output of the hair length sensor is OFF in step S2, it is determined in step S4 that the person to be washed has long hair, and a long hair wash coat is set. Thus, when the hair washing course is automatically set, the "pause" flag is set to 0 in step S5, the hair washing process from step S6 is started, and the timer starts counting.

When the cleaning process is started, the start key 3
Based on the operation of 1, the setting of whether the main washing, the rinsing 1 and the treatment and the rinsing 2 are performed in standard time or long time is set. That is, if the 1 start key 31 is not pressed within 5 seconds after the start of the hair washing process in steps S9 and S10,
In step S11, the standard time is set. Based on this, the hair washing operation is performed in step S19. It returns to step S6 until the hair washing time has passed in step S20, and when the hair washing time has passed, step S2
At 1, the washing operation is completed.

On the other hand, if the start key 31 is pressed again within 5 seconds after the start of the hair washing process in step S10, the long time is set in step S12, and the hair washing operation is performed in accordance with the long time in step S19. . If the start key 31 is pressed again within 5 seconds after setting the long time, the "pause" flag is set to 1 in step S13, and the process proceeds to step S14. Then, in step S14, the output is turned off and the timer count is stopped.
After 15, the process returns to step S6. That is, the operation is temporarily stopped until the start key 31 is pressed next time. When the start key 31 is pressed again in step S15 after the temporary stop, the "temporary stop" flag is set to 0 in step S16.
Is set, and the process returns to step S6. This allows
Output OFF and timer count stop state are released,
Restart.

That is, if the start key 31 is not pressed within 5 seconds after the start, the standard time is set. If the start key 31 is pressed again within 5 seconds after the start, the long time setting is set, and the start key 3 is pressed again.
Press 1 to stop. As a result, the standard time course → long time course → stop is repeated each time the start key 31 is pressed.

As described above, by simply pressing the start key 31 within a predetermined time after the start of the hair-washing process, the hair-washing content (washing time) of the washing course can be changed. A wide range of hair washing contents can be selected according to the difference in the above. As a result, the washing effect and the massage effect on the person to be washed can be increased. In addition, after 5 seconds have passed from the start of the hair washing process, step S17
When the start key 31 is pressed at step S
At 18, the "pause" flag is set to 1, the process proceeds to step S14, and the process is temporarily stopped until the start key 31 is pressed next.

Regarding the setting of the washing content of the washing course, as shown in the flowchart of FIG. 12, within 5 seconds after the start of the washing process, the washing content of the washing course is standardized every time the start key 31 is pressed. The time and the long time may be set alternately. Note that, in FIG. 12, the step of automatically determining the hair length by the hair length sensor is omitted.

That is, when the start key 31 is pressed, the "pause" flag and the "long time" flag are set to 0 in step S2 to start the hair washing process after step S3, and the timer starts counting. If the start key 31 is not pressed within 5 seconds after the start of the hair washing process, the steps S7, S8 and S are performed.
At 9, the "long time" flag is set to 0 as it is and set to the standard time. If the start key 31 is pressed within 5 seconds after the start, the long time is set to 1 by setting the "long time" flag to 1 in steps S11 and S12 through step S7. Then, if the start key 31 is pressed again within 5 seconds, the "long time" flag is set to 0 in steps S8 and S9 through step S10.
Is set to standard time. Note that other operations are the same as those in the flowchart shown in FIG. 11, so description thereof will be omitted.

FIG. 13, FIG. 14, FIG. 15 and FIG. 16 are flowcharts showing the control contents of the hair washing operation. FIG.
The flow of control of the hair washing operation will be described with reference to FIGS. 3, 14, 15, and 16. In the following description, it is assumed that the full course is selected as the short hair washing course. First, referring to FIG. 13, when the cleaning operation starts,
First, in steps S30 and S31, time t1 (5 seconds)
The initial drainage is performed until the time elapses. What is initial drainage?
The water first accumulated in the outflow pipe 96, the pump 95, the upper nozzle link 55, the lower nozzle link 58, and the like (this water is different from the hot water in the hot water storage tank 87 and is normally cooled water). It is to drain. When entering the initial drainage stroke, first, the link motor 71 is rotated clockwise to shake the upper nozzle link 55 so that the cooled water sprayed from the upper nozzle link 55 does not reach the head of the person to be washed as much as possible during the initial drainage. When the second reed switch MS2 detects the lower position of the upper nozzle link 55, the link motor 71 is stopped and the upper nozzle link 55 is stopped at the lower position (see * 10 in FIG. 9). Then, while driving the pump 95 at the frequency f1 (for example, 7 Hz), the upper nozzle valve 96A and the lower nozzle valve 96B are turned on, and the initial drainage from the nozzles 57 and 59 arranged in the upper and lower nozzle links 55 and 57. I do.

When the initial drainage process is completed, the weak cleaning is performed until the time t2 (15 seconds) elapses in steps S32 and S33. When entering the light cleaning process, the frequency f
While driving the pump 95 at 2 (for example, 24 Hz), the upper nozzle valve 96A and the lower nozzle valve 96A
When B is turned on, the link motor 71 is rotated clockwise until the first reed switch MS 1 detects the horizontal position of the upper nozzle link 55, and the reed switch MS1 detects the horizontal position of the upper nozzle link 55. , The link motor 71 is stopped. And, the upper nozzle link 5 for a certain period of time
5 is stopped at the horizontal position, and washing water is sprayed from above and below to perform weak washing (see * 11 in FIG. 9).

In this way, the upper nozzle link 55 is maintained for a certain period of time.
By stopping the washing at a horizontal position to wash the hair, you can apply the washing water to the top of the hair-washed person's head in order to familiarize yourself with the jetting force and temperature of the washing water, like when you wash your hair by hand. It is possible to alleviate the concern that the person to be washed may tickle or that the wash water may be sprayed to the face due to the sudden swing of the upper nozzle link 55 within a predetermined angle range. In addition, in order to further enhance the above effect, it is preferable to gradually increase the pump pressure.

When the above weak cleaning process is completed, step S
In 34 to S36, pre-washing is performed until the time t3 (18 seconds) elapses. When entering the pre-washing step, first in step S34, the upper nozzle valve 96 is driven while driving the pump 95 at the frequency f3 (for example, 30 Hz).
A, the valve 96B for the lower nozzle is turned on. Then, in step S35, the link motor 71 is rotated in the normal and reverse directions at predetermined intervals to generate the upper nozzle link 55 and the lower nozzle link 58.
Repeatedly oscillate in small increments to spray prewash water from above and below to perform prewash scrubbing. The rotation control of the link motor 71 (corresponding to * 3 in FIG. 9) in this rubbing stroke will be described in detail later.

Referring to FIG. 14, when the pre-washing step is completed, the pre-washing step is introduced into the main washing step of steps S37 to S49. That is, in the main wash process, first, step S37,
Only main washing is performed until the time t4 (30 seconds) elapses in S38. When entering the process only under main washing, the frequency f
While driving the pump 95 at 4 (for example, 42 Hz), the upper nozzle valve 96A is turned off, the lower nozzle valve 96B and the shampoo valve 102 are turned on, and the lower nozzle link 58 is rotated to be arranged on the lower nozzle link 58. Only the main washing is performed by spraying washing water from the nozzle 59.

When the process is completed only for main washing, step S
In 39 to S41, the main washing is performed until the time t5 (18 seconds when the standard time is set and 30 seconds when the long time is set) has elapsed. When entering the main washing step, first in step S39, the upper nozzle valve 96A, the lower nozzle valve 96B, and the shampoo valve 102 are turned on. Then, in step S35, as in the pre-washing step, the link motor 71 is normally and reversely rotated at predetermined time intervals, and the upper nozzle link 55 and the lower nozzle link 58 are repeatedly swung in small increments to spray the washing water from the vertical direction. Do main washing.

When the main-washing step is completed, step S4
2. In S43, main washing is continuously performed until the time t6 (6 seconds) elapses. When the main washing continuous process is started, the upper nozzle valve 96A, the lower nozzle valve 96B and the shampoo valve 102 are turned on, and the upper nozzle link 5
5 and the lower nozzle link 58 are rocked to continue the main washing.

When the continuous main washing process is completed, step S4
In 4 to S46, the main washing spot is performed until the time t7 (18 seconds) elapses. When entering the main wash spot process,
First, in step S 44, the valve for the upper nozzle 96A, the valve for a lower nozzle 96B and the shampoo valve 102 O
N Then, at step S4 5, the upper nozzle link 5
While swinging 5 and the lower nozzle link 58, cleaning water is jetted from the up and down direction to perform a predetermined spot stroke.

When the main-wash spot step is completed, the main-wash is again performed until the time t8 (18 seconds when the standard time is set and 30 seconds when the long time is set) has elapsed in steps S47 to S49. Upon entering the second main-washing step, first in step S47, the upper nozzle valve 96
A, lower nozzle valve 96B and shampoo valve 1
Turn 02 on. Then, in step S48, the link motor 71 is rotated in the normal and reverse directions at predetermined time intervals in the same manner as the second main-washing step so that the upper and lower nozzle links 55 and 5
8 is repeatedly oscillated in small increments, and washing water is sprayed from above and below to perform main washing scrubbing.

Referring to FIG. 15, the above steps S37-.
When the main washing step of S49 is completed, steps S50 to S5
8 rinses are put into one stroke. That is, in the rinsing one stroke, first, at step S50, time t9 (30
Rinsing 1 up and down until (seconds) has elapsed. Rinse 1
In the vertical stroke, the upper nozzle valve 96A and the lower nozzle valve 96B are alternately turned on, and the upper nozzle link 55 and the lower nozzle link 58 are rocked,
Rinsing 1 is performed by spraying the wash water alternately from above and below. The control of the upper nozzle valve 96A and the lower nozzle valve 96B related to the vertical injection will be described in detail later.

When the rinsing 1 up and down stroke is completed, rinsing 1 is continuously performed until the time ta (6 seconds) elapses in steps S51 and S52. When entering the rinse 1 continuous stroke,
Valve for the upper nozzle 96A and the valve for the lower nozzle 96 B
Together with turns ON, the upper nozzle link 55 and the lower nozzle link 58 is pivoted, performs injection to rinse 1 continuously wash water from above and below.

When the rinsing one continuous process is completed, one rinsing spot is performed until the time tb (18 seconds) elapses in steps S53 to S55. When the rinsing 1-spot process is started, first in step S53, the upper nozzle valve 96A and the lower nozzle valve 96B are turned on. Then, in step S54, the upper nozzle link 55 and the lower nozzle link 58 are swung, and the cleaning water is jetted from above and below to perform a predetermined spot stroke.

When the rinsing 1 spot process is completed, rinsing 1 rubbing is performed until the time tc (18 seconds when the standard time is set and 30 seconds when the long time is set) elapses in steps S56 to S58. When the rinse 1 fir stroke is started, first in step S56, the upper nozzle valve 96
A and the valve 96B for the lower nozzle are turned on. And
In step S57, similarly to the main washing, the link motor 71 is normally and reversely rotated at predetermined intervals, and the upper nozzle link 55 and the lower nozzle link 58 are repeatedly swung in small increments.
Rinsing 1 is carried out by spraying washing water from above and below.

Referring to FIG. 16, steps S50-
When one rinse step of S58 is completed, step S59,
In S60, the time td (24 when the standard time is set)
Treatment is performed until seconds, 30 seconds when long time is set). Upon entering the treatment process, the upper nozzle valve 96A and the lower nozzle valve 9
While ON treatments valve 104 to 6 B rabbi, the upper nozzle link 55 and the lower nozzle link 58
Rock and spray the washing water from above and below for treatment.

When the treatment process is completed, rinsing 2 is performed in steps S61 and S62 until the time te (18 seconds when the standard time is set and 30 seconds when the long time is set) elapses. When entering the rinsing 2 stroke, valve 96A for the upper nozzle and valve 9 for the lower nozzle
With turning ON 6 B, the upper nozzle link 55 and the lower nozzle link 58 is pivoted, performs rinsed 2 washing water is jetted from above and below.

When the rinsing two strokes are completed, all outputs are turned off in step S63, and the hair washing operation is completed. When all outputs are stopped once at the end, a water hammer phenomenon occurs, so the pump 95 is first stopped to stop other outputs. Further, after the end, when the operator uses the hand shower 8 to perform auxiliary washing such as finishing of hair wash, the upper nozzle link 55 is stopped at the lower position so as not to get in the way ( 9 * 12).

Main washing, main washing continuous and rinsing 1
Inverter 10 in continuous and rinse 1 fir stroke
The frequency outputs of 6 (see * 4 in FIG. 9) are output according to the pressure settings of the long hair washing course and the short hair washing course, as shown in Table 1 below. Table 1 shows the relationship between pressure setting and frequency.

It is a fixed one that is predetermined.

[Table 2]

Further, the frequency output of the inverter 106 in the main washing spot and the rinsing 1 spot stroke is such that when the short hair washing course is selected, it is repeated at 24 HZ (1 second)-[setting + pressure frequency in two steps] Hz (1 second). It is performed (see * 1 in FIG. 9), and when the long hair washing course is selected, it is performed by repeating 30HZ (1 second)-[setting + pressure frequency in two steps] Hz (1 second) (see * 2 in FIG. 9). .

Further, as shown in FIG. 9, the pump 95 is stopped for 0.3 seconds during the transition from the main washing only to the main washing scrubbing and rinsing 1 up and down 1 and rinsing 1 continuous (see * 13). Is only from under the main wash) and rinse 1
This is to prevent the water hammer phenomenon resulting from the large pressure fluctuation when switching the valve from the top to the bottom when switching to one continuous rinse.

FIG. 17 is a flow chart showing the control contents in the rice fir stroke. With reference to FIG. 17, the flow of control in the fir stroke will be described in detail. When the fir process starts, steps S100 and S101
Then, the link motor 71 is rotated clockwise for 1.5 seconds. When 1.5 seconds have passed, steps S102 and S10 are performed.
At 3, the link motor 71 is stopped for 0.1 second. Then, in steps S104 and S105, the link motor 71 is
To the left for 1.0 second. Then, when 1.0 second has elapsed, the link motor 71 is stopped in step S106, and in step S108, it is determined whether or not the set time T (t3, t5, tc) of each fir stroke shown in FIG. 10 has elapsed. It
If the set time T has not elapsed, step S1
When the set time T is returned to 00, the rice fir stroke is ended and the process moves to the next stroke.

In this way, by rotating the link motor 71 forward and backward at regular intervals, the upper nozzle link 55 in particular swings repeatedly in small increments as shown in FIG. 19, so it is arranged on this nozzle link 55. The washing water sprayed from the nozzle 57 can give an appropriate stimulus to the head of the person to be washed and make the person to be washed feel like he / she is washing the hair with his / her hands. Therefore, the massage on the head and the cleaning effect can be improved.

Further, as described above, the setting time T of the rubbing process is set to be the standard time or the long time according to the difference in the hairstyle and the amount of hair of the person to be washed. . Therefore, when the long time is set, the fir stroke time becomes long. That is,
Since the rubbing stroke time is selected depending on the hairstyle, the amount of hair, etc. of the person to be washed, the washing effect and the feeling of massage can be increased according to the person to be washed.

FIG. 18 is a flow chart showing the control contents in the vertical injection stroke. The control flow of the upper and lower alternate injection strokes in the rinse 1 will be described in detail with reference to FIG. When the upper and lower alternate injection process starts, the upper and lower alternate injection count I is cleared in step S200, and first, in steps S201 and S202, time t9a (2 to 3 seconds: standard time <long time)
The wash water is sprayed only from below until the time passes. That is,
While driving the pump 95 at a frequency f9 (for example, 42 Hz), the upper nozzle valve 96A is turned off, the lower nozzle valve 96B is turned on, and the lower nozzle link 58 is rotated to be arranged on the lower nozzle link 58. The cleaning water is sprayed only from the nozzle 59.

When the injection of the washing water only from below is completed, the time t9b is reached in steps S203 and S204.
(2 to 3 seconds: However, the standard time <long time), the cleaning water is sprayed only from the lower side. That is, the frequency f
While driving the pump 95 at 9 (for example, 42 Hz), the upper nozzle valve 96A is turned on, the lower nozzle valve 96B is turned off, and the upper nozzle link 55 is swung to arrange the nozzles arranged in the upper nozzle link 55. The washing water is sprayed only from 57.

When the injection of the washing water from above only is completed, the up / down alternate injection count I is incremented by +1 in step S204, the process returns to step S201, and again the injection from below only in steps S201 and S202 and step S203. , S20 is performed only from above. Then, when the upper and lower alternate injection count I reaches 5 in step S206, the upper and lower alternate injection stroke is ended, and the process proceeds to the next stroke. It should be noted that instead of managing by the upper and lower alternate injection count, it may be managed by the total upper and lower alternate injection time.

In this way, as in the previous step, that is, the step of rinsing 1 from the main washing rice to the upper and lower steps, the washing water is not sprayed from the vertical direction at the same time, but the washing water is sprayed so as to have a change in the spraying pattern. By alternately jetting water from the vertical direction, it becomes difficult for the person to be washed to predict from which direction the washing water will be jetted. Therefore, it is possible to prevent the person to be washed from getting accustomed to the stimulation of the scalp by the jetting force of the washing water, and in this respect as well, the washing effect and the feeling of massage can be increased.

The present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made within the scope of the present invention. In the above-mentioned embodiment, the washing time of the washing course is set to 2 of standard time and long time.
Although it is possible to set the type of hair, if the setting can be made in three or more steps, it becomes possible to select a wide range of fir strokes according to the person to be washed. Further, it is preferable that the display is performed so that it can be seen whether the standard time or the long time is set.

In the above embodiment, the upper and lower alternate injection strokes are applied to the rinsing one stroke, but this upper and lower alternate injection strokes may be applied to the main wash stroke. Further, the upper and lower alternate injection strokes may be applied to both the main wash stroke and the first rinse stroke, or this stroke may be newly added to the main wash stroke and the first rinse stroke. In short, the spray pattern of the wash water may be changed as the washing process progresses so that the person to be washed cannot predict the jet direction.

Further, although the intervals of the upper and lower alternate injection directions in the upper and lower alternate injection strokes are set to be constant, if the intervals are irregular, it becomes more difficult to predict the injection directions. Therefore, the cleaning effect and the feeling of massage can be further increased.

[0100]

As is apparent from the above description, according to claim 1 of the present invention, since the hair washing operation contents can be widely selected according to the type of hairstyle and the amount of hair of the person to be washed, the person to be washed can The cleaning effect and the feeling of massage can be increased.
According to the second aspect, it is possible to make it difficult to predict from which direction the washing water will be jetted to the person to be washed by changing the jetting direction of the washing water during the washing process. , The washing effect on the person to be washed and the feeling of massage can be increased.
