The upper nozzle link 11 is a tubular member that is curved in a generally arcuate shape that is convex upward at the illustrated position so as to follow the head of the person to be washed, and has a nozzle at a predetermined interval, and the left end portion thereof rotates. It is supported in a cantilevered manner and sprays wash water toward the head of the person being washed.
The lower nozzle link 12 is a tubular member that is curved in a substantially arch shape convex to the left at the illustrated position so as to surround the hair of the person to be washed, and has nozzles at predetermined intervals. The cantilever is rotatably supported below the link 11. The lower nozzle link 12 cleans the hair (shown by an imaginary line) of the person to be washed that hangs down on the rear side by spraying washing water backward. In the sink 2, a neck nozzle link 80 for spraying cleaning water toward the neck of the hair-washed person in a supine posture is disposed.

  The upper and lower nozzle links 11 and 12 and the neck nozzle link 80 are each provided with a plurality of nozzles, and are sent into the upper and lower nozzle links 11 and 12 and the neck nozzle link 80 at the time of washing the hair. Wash water is sprayed from each nozzle. The upper and lower nozzle links 11 and 12 rotate, and the neck nozzle link 80 is fixed. By spraying washing water from each nozzle, the head and the entire hair of the person to be washed can be washed. A hand shower 13 is disposed on the upper rear side in the sink 2. An operator (such as a beauty salon employee) can manually wash the hair by turning the cock 14 arranged to the right of the hand shower 13 to adjust the amount of water discharged from the hand shower 13.

  As shown in FIG. 3, the water used in the automatic hair washing machine 1 is supplied into the machine via a mixing valve 15 and a water supply pipe 16 from a water supply facility and a hot water supply facility (not shown) outside the device. Water is supplied to the mixing valve 15 from the water supply facility via the water supply unit 17 and hot water is supplied from the hot water supply facility via the hot water supply unit 18. The mixing valve 15 is for mixing the water and hot water supplied from the water supply unit 17 and the hot water supply unit 18 and sending them to the water supply pipe 16 as hot water. A thermistor 19 for detecting the temperature of hot water sent out from the mixing valve 15 is disposed in the middle of the water supply pipe 16. When the motor 20 is driven based on the detection result of the thermistor 19, the mixing valve 15 is opened and closed, the mixing ratio of water and hot water is adjusted, and hot water having a set temperature is generated. The mixing valve 15 is an electric type that is adjusted by the motor 20. The motor 20 is a DC motor or a DC motor, and includes a brush or the like.

  An operation panel 60 (FIG. 2) is provided on the side of the sink 2, and the set temperature is determined by the operator (user) operating the operation panel 60. The water supply pipe 16 branches into a hand shower water supply pipe 21 and a hot water storage water supply pipe 22 from an intermediate portion (downstream of the thermistor 19). The hand shower water supply pipe 21 communicates with the hand shower 13 through a hand shower valve 23 that can be opened and closed by a cock 14. On the other hand, the hot water storage water supply pipe 22 can supply hot water into the hot water storage tank 25 via a hot water storage valve 24 as a hot water supply valve.

  Inside the hot water storage tank 25, a first water level sensor 26 and a second water level sensor 27 for detecting the water level of the hot water stored in the hot water storage tank 25 are arranged at regular intervals in the vertical direction. . When the hot water in the hot water storage tank 25 is used and the second water level sensor 27 detects that the predetermined minimum water level has been reached, the hot water storage valve 24 is opened and hot water is supplied into the hot water storage tank 25. The Thereafter, when the first water level sensor 26 detects that the hot water in the hot water storage tank 25 has reached a predetermined maximum water level, the hot water storage valve 24 is closed and the supply of hot water is stopped. In this way, hot water is always stored in the hot water storage tank 25 between the lowest water level and the highest water level.

  In the upper part of the hot water storage tank 25 (above the first water level sensor 26), when hot water of a maximum water level or higher is supplied into the hot water storage tank 25 due to a failure of the first water level sensor 26, the excess An overflow port 28 for allowing the hot water to overflow to the outside of the hot water storage tank 25 is formed. The hot water overflowing from the overflow port 28 is received by the overflow tank 29 and discharged outside the machine through the drain pipe 30 communicating with the overflow tank 29. An overflow sensor 31 is disposed in the overflow tank 29. For example, when the overflow sensor 31 detects that the drain pipe 30 is clogged and the water level in the overflow tank 29 has reached the maximum water level, the automatic hair washer 1 Operation is stopped.

  The other end of the suction pipe 33 whose one end is connected to the main pump 32 is connected to the lowermost part of the hot water storage tank 25. The main pump 32 is driven by being supplied with an alternating current from the inverter, and sucks hot water in the hot water storage tank 25 through the suction pipe 33. In the middle of the suction pipe 33, a shampoo supply pipe 35 leading to a shampoo container 34 containing shampoo liquid and a conditioner supply pipe 37 leading to a conditioner container 36 containing conditioner liquid are connected. The conditioner container 36 may contain a treatment liquid. A shampoo pump 38 and a conditioner pump 39 are provided in the middle of the shampoo supply pipe 35 and the conditioner supply pipe 37, respectively, and pass through the suction pipe 33 by the functions of the shampoo pump 38 and the conditioner pump 39. By appropriately adjusting the mixing amount of the shampoo liquid and the conditioner liquid into the hot water, the main pump 32 is pumped with cleaning water to be used at that time.

  The wash water sucked into the main pump 32 from the suction pipe 33 is sent out to the water supply pipe 40 having a plurality of (for example, four) shunts. A filter 41 is provided in the water supply pipe 40, and four valves, an upper nozzle valve 42, a lower nozzle valve 43, a neck nozzle valve 74, and a drain valve 44, are provided at four downstream branches. Is provided. Branch paths 46, 47, 75, and 48 are extended in four shunts provided with the upper nozzle valve 42, the lower nozzle valve 43, the neck nozzle valve 74, and the drain valve 44, respectively. The end of the branch path 46 extending from the upper nozzle valve 42 is connected to the upper nozzle link 11, and the end of the branch path 47 extending from the lower nozzle valve 43 is connected to the lower nozzle link 12, The terminal end of the branch path 75 extending from the valve 74 is connected to the neck nozzle link 80.

  A discharge port 50 for discharging water into the sink 2 is formed on the bottom surface of the sink 2, and the discharge port 50 communicates with the drain pipe 30 via a drain trap 51 for preventing backflow. is doing. As a result, the water discharged from the discharge port 50 of the sink 2 passes through the drain pipe 30 and is drained outside the machine. A terminal end of a branch path 48 extending from the drain valve 44 is connected to a drain trap 51.

The upper nozzle link 11 and the lower nozzle link 12 are both configured to be cantilevered and can be repeatedly moved synchronously.
Specifically, referring to FIG. 2B, the upper nozzle link 11 starts to rotate in the direction of arrow C around the rotation axis A, rotates from the top position T1 shown in FIG. Repetitive movement is possible by reaching T2 and then reversely rotating in the direction of arrow E and returning to the crown position T1. Here, when the upper nozzle link 11 is at the head top position T1, washing water is sprayed from each of the nozzles formed on the upper nozzle link 11 in the direction of the arrow Y1, thereby washing near the top of the head of the person being washed. Since water is jetted, the parietal position T1 is a position corresponding to the parietal part of the head of the person to be washed. In addition, when the upper nozzle link 11 is at the occipital position T2, cleaning water is jetted from each of the nozzles formed on the upper nozzle link 11 in the direction of the arrow Y2. Since it is ejected, the occipital position T2 is a position corresponding to the occipital region of the head of the person being washed.

  On the other hand, the lower nozzle link 12 starts rotating in the arrow D direction around the rotation axis B, rotates from the hair position T3 shown in FIG. 2, reaches the neck position T4, and then reversely rotates in the arrow F direction therefrom. Thus, it is possible to repeatedly move back to the hair position T3. Here, when the lower nozzle link 12 is at the hair position T3, the cleaning water is jetted from the respective nozzles formed on the lower nozzle link 12 in the direction of the arrow Y3, and the washing water is jetted to the hair drooped by the user. Therefore, the hair position T3 is a position corresponding to the hair that hangs down from the head housed in the sink 2. Further, when the lower nozzle link 12 is at the neck position T4, cleaning water is sprayed in the direction of the arrow Y4 from each of the nozzles formed on the lower nozzle link 12, and the cleaning water is sprayed near the neck of the person to be washed. Therefore, the neck position T4 is a position corresponding to the neck of the person to be washed.

In the present embodiment, the upper nozzle link 11 and the lower nozzle link 12 are moved in the same direction synchronously as follows by a drive mechanism 89 (FIG. 4) described later.
That is, referring to FIG. 2B, when the upper nozzle link 11 is located at the top position T1, the lower nozzle link 12 is located at the hair position T3. Then, assuming that the upper nozzle link 11 is located at the top position T1 and the lower nozzle link 12 is located at the hair position T3, when the upper nozzle link 11 starts to rotate in the direction of arrow C, the lower nozzle link 12 is also synchronized. Then, rotation starts in the direction of arrow D, and when the upper nozzle link 11 reaches the occipital position T2, the lower nozzle link 12 reaches the neck position T4 substantially simultaneously. Furthermore, after the upper nozzle link 11 reaches the occipital position T2 and the lower nozzle link 12 reaches the neck position T4, each of these nozzle links is reversed and moved. That is, assuming that the upper nozzle link 11 is at the occipital position T2 and the lower nozzle link 12 is at the neck position T4, when the upper nozzle link 11 starts rotating in the direction opposite to the arrow C, the lower nozzle link 12 is also synchronized with the arrow. The rotation starts in the direction opposite to D, and when the upper nozzle link 11 reaches the top position T1, the lower nozzle link 12 reaches the hair position T3 at the same time.

Here, for example, the upper nozzle link 11 moves in the same direction as the hair grows while spraying the cleaning water, while the lower nozzle link 12 moves in the opposite direction to the hair grows while spraying the cleaning water, etc. When the movement directions of the upper nozzle link 11 and the lower nozzle link 12 with respect to the direction in which the hair grows are different, the upper nozzle link 11 and the lower nozzle link 12 each have their hair washed from different directions with respect to the direction in which the hair grows. The cleaning water will be sprayed on the person's head and hair, which may cause the hair to become tangled.
However, as described above, since the upper nozzle link 11 and the lower nozzle link 12 are configured to move in the same direction synchronously, each of the upper nozzle link 11 and the lower nozzle link 12 with respect to the hair growth direction. It is possible to prevent a situation in which the moving directions always coincide and the hair gets tangled.
Furthermore, during the movement of the upper nozzle link 11 and the lower nozzle link 12, it is possible to ensure that these nozzle links do not contact.
Although details will be described later, in this embodiment, the upper nozzle link 11 and the lower nozzle link 12 move at different speeds while being synchronized or controlled within a certain range under the control of the microcomputer (FIG. 4). Complex movements are possible, such as pausing after moving, or repetitive movement within a predetermined range.

  Next, the drive mechanism 89 that realizes the synchronized movement of the upper nozzle link 11 and the lower nozzle link 12 as described above will be described.

FIG. 4A is a left side view of the sink 2 in a state where the sink holding base 3 is removed and the side surface of the sink 2 is exposed. In this figure, the microcomputer 92 is schematically shown. FIG. 4B is a front view of the sink 2 in this state (a front view showing a substantially left half in a front view).
As shown in FIG. 4A, a stepping motor 91 is provided at the lower portion of the left side surface 90 of the sink 2. The stepping motor 91 is connected to a motor drive circuit (not shown). Under the control of the microcomputer 92, a drive pulse is input from the motor drive circuit, and a predetermined direction is determined in a predetermined direction based on the input drive pulse. Rotate by distance. As is well known, since the momentum of the stepping motor 91 is defined in proportion to the number of drive pulses, accurate positioning control by the microcomputer 92 can be realized.

A power transmission mechanism 101 that transmits the rotational driving force of the stepping motor 91 to the upper nozzle link 11 and the lower nozzle link 12 is connected to the stepping motor 91.
Hereinafter, the power transmission mechanism 101 will be described in detail.

A lower gear 93 is provided above the stepping motor 91. A lower timing belt 94 is wound around the lower gear 93 and a pulley (not shown) attached to the rotor shaft of the stepping motor 91 to transmit the rotational driving force of the stepping motor 91 to the lower gear 93. In response to the rotation of the stepping motor 91, the lower gear 93 is rotated at a predetermined reduction ratio.
The lower nozzle link 12 is connected to the output shaft of the lower gear 93, and the lower nozzle link 12 rotates according to the rotation of the lower gear 93. Specifically, when the lower gear 93 rotates in the arrow X direction shown in FIG. 4A, the lower nozzle link 12 rotates in the direction from the hair position T3 to the neck position T4 (the direction indicated by the arrow D). When the lower gear 93 rotates in the direction indicated by the arrow Y shown in FIG. 4A, the lower nozzle link 12 rotates in the direction from the neck position T4 toward the hair position T3 (direction indicated by the arrow F). Move. The lower nozzle link 12 is configured to rotate between the hair position T3 and the neck position T4 in synchronization with the upper nozzle link 11 under the control of the microcomputer 92. This will be described later. To do.

An upper gear 96 that meshes with the lower gear 93 is provided above the lower gear 93. The upper gear 96 rotates in the direction opposite to the rotation direction of the lower gear 93 according to the rotation of the lower gear 93.
A pulley 97 is provided above the upper gear 96, and an upper timing belt 98 for transmitting the rotational driving force of the upper gear 96 to the pulley 97 is wound around the upper gear 96 and the pulley 97. Thus, the pulley 97 rotates in accordance with the rotation of the upper gear 96.
The upper nozzle link 11 is connected to the output shaft of the pulley 97, and the upper nozzle link 11 rotates according to the rotation of the upper gear 96. Specifically, when the upper gear 96 rotates in the arrow Y direction shown in FIG. 4A (at this time, the lower gear 93 rotates in the arrow X direction), the upper nozzle link 11 moves from the top position T1. When the upper gear 96 is rotated in the direction indicated by the arrow X shown in FIG. 4A (the lower gear 93 is rotated in the direction indicated by the arrow Y). The upper nozzle link 11 rotates in a direction (a direction indicated by an arrow E) from the occipital position T2 toward the top position T1. The upper nozzle link 11 is configured to rotate between the top position T1 and the back position T2 in synchronization with the lower nozzle link 12 under the control of the microcomputer 92. This will be described later. .

Next, the synchronized movement of the upper nozzle link 11 and the lower nozzle link 12 accompanying the drive of the drive mechanism 89 will be described in detail.
First, it is assumed that the upper nozzle link 11 is located at the top position T1, and the lower nozzle link 12 is located at the hair position T3. In this case, the microcomputer 92 rotates the stepping motor 91 in the direction of arrow X in FIG. As the stepping motor 91 rotates in the arrow X direction, the lower gear 93 rotates in the arrow X direction, and as the lower gear 93 rotates in the arrow X direction, the lower nozzle link located at the hair position T3. 12 rotates in the direction of arrow D.
Further, as the lower gear 93 rotates in the arrow X direction, the upper gear 96 rotates in the arrow Y direction, and as the upper gear 96 rotates in the arrow Y direction, the pulley 97 rotates in the arrow Y direction. As the pulley 97 rotates in the arrow Y direction, the upper nozzle link 11 located at the top position T1 rotates in the arrow C direction.
In this way, the lower nozzle link 12 moves from the hair position T3 toward the neck position T4 in synchronization with the movement of the upper nozzle link 11 from the top position T1 toward the occipital position T2.

Furthermore, when the lower nozzle link 12 reaches the neck position T4 as a result of the rotation of the lower nozzle link 1 in the arrow D direction, the upper nozzle link 11 reaches the occipital position T2 at the same time. That is, in this embodiment, the upper gear 96, the lower gear 93, the pulley 97, and other nozzle links are arranged so that the upper nozzle link 11 reaches the occipital position T2 at the same time that the lower nozzle link 12 reaches the neck position T4. The member which concerns on rotation of is designed.
When the lower nozzle link 12 reaches the neck position T4 and the upper nozzle link 11 reaches the occipital position T2 together with this, the stepping motor 91 is shown in FIG. 4A under the control of the microcomputer 92. It rotates clockwise (in the direction indicated by arrow Y in FIG. 4A).
As the stepping motor 91 rotates in the arrow Y direction, the lower gear 93 rotates in the arrow Y direction, and as the lower gear 93 rotates in the arrow Y direction, the lower nozzle located at the neck position T4. The link 12 rotates in the direction of arrow F.
Further, as the lower gear 93 rotates in the arrow Y direction, the upper gear 96 rotates in the arrow X direction, and as the upper gear 96 rotates in the arrow X direction, the pulley 97 rotates in the arrow X direction. As the pulley 97 rotates in the arrow X direction, the upper nozzle link 11 positioned at the occipital position T2 rotates in the arrow E direction.
In this way, the lower nozzle link 12 moves from the neck position T4 toward the hair position T3 in synchronization with the movement of the upper nozzle link 11 from the occipital position T2 toward the crown position T1.

  The fact that the lower nozzle link 12 has reached the hair position T3 and that it has reached the neck position T4 is based on the number of rotation steps calculated from the number of drive pulses input to the stepping motor 91. It is detected as appropriate.

Further, as shown in FIG. 4A, the upper gear 96 is provided with a gear position detection switch 100. The gear position detection switch 100 detects that the upper nozzle link 11 has rotated in the direction of arrow E beyond the top position T1, and that the upper nozzle link 11 has been rotated in the direction of arrow C beyond the back position T2. This is a magnet type sensor. When the upper gear 96 rotates in the direction of arrow X so that the upper nozzle link 11 rotates in the direction of arrow E beyond the top position T1, a gear position detection switch is provided by a magnet (not shown) provided in the upper gear 96. 100 contacts are conducted, and a signal to that effect is output to a predetermined port of the microcomputer 92. The microcomputer 92 to which the signal is input stops driving the stepping motor 91, thereby preventing the upper nozzle link 11 from rotating in the direction of arrow E beyond the top position T1. At the same time, the lower nozzle link 12 that moves in synchronization with the upper nozzle link 11 is prevented from rotating in the direction of arrow F beyond the hair position T3.
Similarly, when the upper gear 96 is rotated in the arrow Y direction so that the upper nozzle link 11 is rotated in the arrow C direction beyond the occipital position T2, a gear (not shown) provided in the upper gear 96 The contact of the position detection switch 100 becomes conductive, and a signal to that effect is output to a predetermined port of the microcomputer 92. The microcomputer 92 to which the signal is input stops driving the stepping motor 91, thereby preventing the upper nozzle link 11 from rotating beyond the occipital position T <b> 2 in the arrow C direction. At the same time, the lower nozzle link 12 moving in synchronization with the upper nozzle link 11 is prevented from rotating in the direction of arrow D beyond the neck position T4.

As described above, the automatic hair washing machine 1 according to the present embodiment includes the upper nozzle link 11 and the lower nozzle link 12 that inject washing water to different parts of the head, and each of these nozzle links is a single unit. The power transmission mechanism connected to the stepping motor 91 is configured to be movable in synchronization.
According to this, the nozzle links of the upper nozzle link 11 and the lower nozzle link 12 are moved in synchronization by moving the nozzle links of the upper nozzle link 11 and the lower nozzle link 12 via a power transmission mechanism connected to a single stepping motor 91. It becomes possible to make it.
In addition, by providing a stepping motor 91 for each nozzle link and controlling each stepping motor 91, the number of stepping motors 91 can be reduced compared with the case of controlling the movement of each nozzle link, and the manufacturing cost can be reduced. This can be realized, and the control program is simplified, thereby improving the manufacturability.

In addition, the automatic hair washer 1 according to the present embodiment has an upper nozzle that is configured to be repeatable from the top position T1 corresponding to the top of the head stored in the sink 2 to the back position T2 corresponding to the back of the head. A link 11 and a lower nozzle link 12 configured to be repeatable between a hair position T3 corresponding to hair hanging from the head housed in the sink 2 and a neck position T4 corresponding to the neck, The lower nozzle link 12 moves in the direction from the hair position T3 to the neck position T4 in synchronization with the movement of the upper nozzle link 11 in the direction from the top position T1 to the occipital position T2, and the upper nozzle link 11 The lower nozzle link 12 moves in the direction from the neck position T4 to the hair position T3 in synchronization with the movement from the occipital position T2 to the top position T1.
Here, for example, the upper nozzle link 11 moves in the same direction as the hair grows while spraying the cleaning water, while the lower nozzle link 12 moves in the opposite direction to the hair grows while spraying the cleaning water, etc. When the movement directions of the upper nozzle link 11 and the lower nozzle link 12 with respect to the direction in which the hair grows are different, the upper nozzle link 11 and the lower nozzle link 12 each have their hair washed from different directions with respect to the direction in which the hair grows. The cleaning water will be sprayed on the person's head and hair, which may cause the hair to become tangled.
However, as described above, since the upper nozzle link 11 and the lower nozzle link 12 are configured to move in the same direction synchronously, each of the upper nozzle link 11 and the lower nozzle link 12 with respect to the hair growth direction. It is possible to prevent a situation in which the moving directions always coincide and the hair gets tangled.
Furthermore, during the movement of the upper nozzle link 11 and the lower nozzle link 12, it is possible to ensure that these nozzle links do not contact.

In this embodiment, the power transmission mechanism 101 includes a lower gear 93 and an upper gear 96 that rotate according to the driving of the stepping motor 91, and the upper nozzle link is utilized by using the rotation of these gears accompanying the driving of the stepping motor 91. 11 and the lower nozzle link 12 can be moved synchronously, and accurate positioning control is possible.
Thus, by providing the power transmission mechanism 101 with the lower gear 93 and the upper gear 96, the rotational driving force of the stepping motor 91 can be appropriately transmitted to the upper nozzle link 11 and the lower nozzle link 12 via these gears. In particular, in the present embodiment, it is necessary to rotate the upper nozzle link 11 and the lower nozzle link 12 in synchronization with each other in the opposite direction. However, after the lower gear 93 and the upper gear 96 are meshed, Since the lower nozzle link 12 is rotated according to the rotation of the upper gear 93 and the upper nozzle link 11 is rotated according to the rotation of the upper gear 96, the upper nozzle link 11 and the lower nozzle link are appropriately and reliably configured. 12 can be rotated synchronously in the opposite direction.

In this embodiment, the gear position detection switch 100 is provided in the upper gear 96, and the microcomputer 92 controls the driving of the stepping motor 91 based on the detection value of the gear position detection switch 100.
More specifically, when the upper gear 96 rotates in the arrow X direction so that the upper nozzle link 11 rotates in the direction of arrow E beyond the top position T1, a magnet (not shown) provided on the upper gear 96 is used. The contact of the gear position detection switch 100 becomes conductive, and a signal to that effect is output to a predetermined port of the microcomputer 92. The microcomputer 92 to which the signal is input stops driving the stepping motor 91, thereby preventing the upper nozzle link 11 from rotating in the direction of arrow E beyond the top position T1. At the same time, the lower nozzle link 12 that moves in synchronization with the upper nozzle link 11 is prevented from rotating in the direction of arrow F beyond the hair position T3.
Similarly, when the upper gear 96 is rotated in the arrow Y direction so that the upper nozzle link 11 is rotated in the arrow C direction beyond the occipital position T2, a gear (not shown) provided in the upper gear 96 The contact of the position detection switch 100 becomes conductive, and a signal to that effect is output to a predetermined port of the microcomputer 92. The microcomputer 92 to which the signal is input stops driving the stepping motor 91, thereby preventing the upper nozzle link 11 from rotating beyond the occipital position T <b> 2 in the arrow C direction. At the same time, the lower nozzle link 12 moving in synchronization with the upper nozzle link 11 is prevented from rotating in the direction of arrow D beyond the neck position T4.

In the present embodiment, the power transmission mechanism 101 is provided on the left side surface 90 of the sink 2.
More specifically, as shown in FIG. 4, the power transmission mechanism 101 is placed on the left side of the sink 2 so that the surfaces of the lower gear 93 and the upper gear 96 that are discs are in a state along the left side surface 90 of the sink 2. The surface 90 is provided. As a result, the thickness of the power transmission mechanism 101 can be reduced, the space formed on the left side of the left side surface 90 of the sink 2 can be effectively utilized, and the power transmission mechanism 101 can be suitably stored, and the automatic hair washer 1 can be miniaturized. Further, the output shafts of the lower gear 93 and the pulley 97 can be made to coincide with the rotation axes of the upper nozzle link 11 and the lower nozzle link 12.
