The present invention relates to a control of an automatic head care system and an automatic hair washing system for use in a medicare or hairdressing and beauty industry.
A hair washing has been known as one of the typical person's head cares. In the hairdressing and beauty industry, the laborious head and/or hair washing has been desired to be automated. Also in the medicare industry, the laborious hair washing services for the inpatients have been expected to be automated.
There has been known an apparatus disclosed in JP 2001-149133 (A), for example, for washing person's hair automatically, which is schematically illustrated in
The washing unit 1 is designed so that, by the driving of reciprocating drive unit 4, the washing unit 1 moves in a direction indicated by an arrow 4c through a rack 4a and a pinion 4b. This arrangement allows the washing unit 1 to broaden a scalp/hair washing range thereof. The washing unit 1, the switching unit 3, and the reciprocating drive unit 4 are supported by a unit support 5. The unit support 5 is designed so as to be driven by a rotational drive unit 6 through a gear assembly 8 to rotate about the support shaft 7, allowing the washing unit 1 to wash the entirety of person's scalp/hair. According to the hair washing apparatus so constructed, the switching unit 3, the reciprocating drive unit 4, and rotational drive unit 6 are driven in combination for the scalp/hair washing. Accordingly, person's scalp/hair is wholly washed automatically, which eliminates laborious human works.
Disadvantageously, the above-described automatic head washing apparatus employs a single washing unit for washing person's scalp/hair by moving the washing unit, which causes a force in the direction of washing unit movement, which is a force in the direction of the person's neck twisting, to apply on the person's head during the washing and as a result, the straining force is applied on person's neck.
The present invention is to solve this problem and provide a method for controlling an automatic head care system and an automatic hair washing system for caring a person's head in an effective manner without applying a straining force on the person's neck.

Moreover, there is provided a method of controlling an automatic head washing system according to the above method, wherein the automatic head washing system includes a pair of pipes with a plurality of nozzles, and a water washing step and a shampoo step are executed in turn between the head receiving step and the care step. In the water step, water or hot water ejected from the plurality of nozzles is poured to the head while the pair of arms are swung. In the shampoo step, washing liquid ejected from the plurality of nozzles is poured to the head while the pair of arms are swung. The care step of caring the head is a massage washing step of kneading and washing the head.
According to the present invention, the method for controlling an automatic head care system and an automatic hair washing system can be provided, which can care a person's head in an effective manner without applying a straining force on the person's neck.
With reference to the accompanying drawings, several embodiments according to the invention will be described hereinafter. Like elements are denoted by like reference numerals to avoid duplicate descriptions. Also, each drawing mainly shows structural element or elements schematically for the better understanding thereof. In the present specification, the term “water” is used in a broader sense including “hot water”. In other words, the term “water” in the present specification means “water or hot water”. In the present specification, the term “hot water” is used in a narrower sense including only “hot water”.
First Embodiment
The automatic head care system described below, according to one embodiment of the invention is to automatically wash person's head. It should be noted that “head care” includes washing person's scalp and hair and massaging person's head throughout the application.
As shown in
The automatic hair washing system 100 comprises a pair of two washing units 12 provided inside the bowl 101 for washing person's head 10 positioned within the bowl 101. In the embodiment, the washing units 12 are made of left washing unit 12L and right washing unit 12R. The left washing unit 12L is an example of first washing unit, and the right washing unit 12R is an example of second washing unit. Although descriptions are made to the hair washing system which is an example of the automatic head care system, the arcuate washing unit serves as an arm unit of the automatic head care system.
The left washing unit 12L has a support shaft 104L coupled to the support column 102L so that it rotates about the support shaft 104L. Likewise, the right washing unit 12R has a support shaft 104R coupled to the support column 102R so that it rotates about the support shaft 104R. In other words, the support shafts 104L and 104R are respectively arranged on left and right sides of the head 10 so as to extend in the lateral direction of the head 10.
As shown in
The pipe 111L of the left washing unit 12L comprises a plurality of nozzles 110 for ejecting at least one of cold water, hot water, washing solution, and conditioner. The nozzles 110 are mounted on a surface opposing the head support 11 of the pipe 111L. The pipe 111L is attached to an arm base 103L fixed to the support shaft 104L, so as to rotate with the rotation of the arm base 103L about the support shaft 104L.
The arms 105L, 106L, 107L, and 108L are attached to the arm base 103L fixed to the support shaft 104L. The first arm 105L is attached to the arm base 103L to rotate with the rotation of the arm base 103L about the support shaft 104L.
The first arm 105L rotatably supports the second arm 106L which in turn rotatably supports two third arms 107L and 108L each carrying a plurality of contacts 109 adapted to make contacts with person's head 10. For this purpose, the contacts 109 are made of flexible rubber material.
The first to third arms 105L, 106L, 107L and 108L are accommodated within an arm housing 115L and the contacts 109 are arranged at the exterior of the arm housing 115L. The second and third arms 106L, 107L and 108L may be supported by the first and second arms 105L and 106L, respectively, so that the arms 106L, 107L and 108L take respective balanced positions automatically.
As shown in
A motor 206L and an arm shaft 209L are mounted within an interior of the arm base 103L. The arm shaft 209L is arranged substantially perpendicular to the support shaft 104L so as to be rotatable about the support shaft 104L with the arm base 103L and the arms 150L, 106L, 107L and 108L. A rotation of the motor 206L is transmitted to the first arm 105L through a gear 207L mounted on the motor output shaft 207La and a gear 208L mounted on an arm shaft 209L of the first arm 105L, which causes the first arm 105L to rotate about the shaft 209L in a direction indicated by an arrow 210L.
The first arm 105L comprises a pressure sensor 211L for detecting a force to be applied on the head 10 and rotatably supports the second arm 106L through the support shaft 212L. The second arm 106L rotatably supports the third arms 107L and 108L through the support shafts 213L and 214L.
As shown in the drawing, a motor 301L is mounted within an interior of the second arm 106L so that a rotation of the motor 301L is transmitted to a drive shaft 304L through a gear 302L mounted on the motor's output shaft and a gear 303L mounted on the drive shaft 304L, which allows the drive shaft 304L to be rotated by the driving of the motor 301L.
A rotation of a gear 305L attached to one end of the drive shaft 304L is transmitted through a cylindrical rack 306L to gears 307L and 311L mounted on the third arm 107L. Therefore, the rotation of the gear 305L causes the cylindrical rack 306L to move along the support shaft 213L, which in turn rotates the gears 307L and the 311L about the rotational shafts 308L and 312L, respectively. The cylindrical rack 306L is rotatably supported by the second arm 106L through the support shaft 213L to move in a direction parallel to the support shaft 213L.
The cylindrical rack 306L is formed cylindrically in its entirety to comprise rack mechanisms 306La defined on its longitudinal opposite side surfaces in a symmetric manner with respect to the longitudinal axis of the rack. The rack mechanism 306La is designed so that it engages with the gear 305L mounted on the drive shaft 304L and the gears 307L and 311L.
The gear 307L carries the fourth arm 309L and two contacts 109 connected by the arm 309L so that the contacts 109 move with the rotation of the gear 307L. Likewise, the gear 311L carries another fourth arm 310L and two contacts 109 connected by the arm 310L so that the contacts 109 move with the rotation of the gear 311L. The fourth arm 309L and 310L serve as a kneading arm unit.
A rotation of a gear 313L attached to the other end of the drive shaft 304L is transmitted through a cylindrical rack 314L to gears 315L and 318L mounted on the third arm 108L. Therefore, the rotation of the gear 313L causes the cylindrical rack 314L to move along the support shaft 214L, which in turn rotates the gears 315L and 318L about the rotational shafts 316L and 319L, respectively. The cylindrical rack 314L is formed cylindrically in its entirety to comprise rack mechanisms 314La defined on its longitudinal opposite side surfaces in a symmetric manner with respect to the longitudinal axis of the rack and is rotatably supported by the second arm 106L through the support shaft 214L to move in a direction parallel to the support shaft 214L.
The gear 315L carries the fourth arm 317L and two contacts 109 connected by the arm 317L so that the contacts 109 move about the rotational shafts 316L with the rotation of the gear 315L. Likewise, the gear 318L carries another fourth arm 320L and two contacts 109 connected by the arm 320L so that the contacts 109 move about the rotational shafts 319L with the rotation of the gear 318L. The fourth arm 317L and 320L serve as a kneading arm unit.
As shown in
Likewise, the cylindrical rack 314L is moved in the direction indicated by arrow 27a with the movement of the cylindrical rack 306L, which causes the gears 315L and 318L provided adjacent to and on opposite sides the cylindrical rack 314L to rotate in the directions indicated by arrows 27b and 27c, respectively. Simultaneously with this, the contacts 109 attached to the gears 315L and 318L through the fourth arms 317L and 320L are moved in opposite directions indicated by arrows 27d and 27e, respectively.
When the cylindrical racks 306L and 314L are moved in the direction indicated by arrow 27a, the adjacent wheels 307L and 318L attached to the adjacent third arms 107L and 108L are rotated in opposite directions. The contacts 109 attached to the wheels 307L and 318L with the fourth arms 309L and 320L interposed therebetween are moved in opposite directions indicated by arrows 27d and 27e. Thus, when the cylindrical racks 306L and 314L are moved in the direction indicated by arrow 27a, the two contacts 109 adjacent in a direction orthogonal to the axial direction of the cylindrical racks 306L and 314L are moved to and away from each other, in the direction indicated by arrows 27d and 27e.
If the cylindrical racks 306L, 314L are moved in the direction indicated by the arrow 27a as the contacts 109 are kept in contact with the scalp of a person, the portions of the scalp under the contacts 109 are frictionally forced to and away from each other, which ensures that person's scalp skins are contracted and stretched and massaged by the contacts.
If the cylindrical racks 306L, 314L are moved in the direction indicated by the arrow 27a as the contacts 109 are kept in contact with the hair of a person, the hair between the contacts 109 is pushed and pulled by the contacts 109, which ensures that person's hair is displaced in various directions and massaged and washed by the contacts.
As shown in
The right washing unit 12R is similar in construction to the left washing unit 12L. The right washing unit 12R comprises arms 105R, 106R, 107R, and 108R and a pipe 111R. The arms 105R, 106R, 107R, and 108R and the pipe 111R are positioned to oppose the head support 11. The pipe 111R is similar in construction to the pipe 111L, and is attached to the arm base 103R fixed to the support shaft 104R.
The arms 105R, 106R, 107R, and 108R are attached to the arm base 103R fixed to the support shaft 104R. The first arm 105R is attached to the arm base 103R to rotate with the rotation of the arm base 103R about the support shaft 104R.
The first arm 105R rotatably supports the second arm 106R which in turn rotatably supports two third arms 107R and 108R each carrying a plurality of contacts 109 adapted to make contacts with person's head 10. The first to third arms 105R, 106R, 107R and 108R are accommodated within an arm housing 115R and the contacts 109 are arranged at the exterior of the arm housing 115R.
As shown in
A motor 206R and an arm shaft 209R are mounted within an interior of the arm base 103R. The arm shaft 209R is arranged substantially perpendicular to the support shaft 104R so as to be rotatable about the support shaft 104R with the arm base 103R and the arms 105R, 106R, 107R and 108R. A rotation of the motor 206R is transmitted to the first arm 105R through a gear 207R mounted on the motor output shaft 207Ra and a gear 208R mounted on an arm shaft 209R of the first arm 105R, which causes the first arm 105R to rotate about the shaft 209R in a direction indicated by an arrow 210R.
The first arm 105R comprises a pressure sensor 211R for detecting a force to be applied on the head 10 and rotatably supports the second arm 106R through the support shaft 212R. The second arm 106R rotatably supports the third arms 107R and 108R through the support shafts 213R and 214R.
Each of the third arms 107R and 108R carries two gears designed to engage with a cylindrical rack. The gear carries a fourth arm and two contacts 109 connected by the fourth arm so that the contacts 109 move with the rotation of the gear by the driving of a motor 301R (see
The second part of the drive mechanism of the automatic hair washing system according to the first embodiment will be further described.
As shown in
In the head care unit 40, the rotation output of the motor 301L is transmitted through the gears 305L and 313L mounted on both ends of the drive shaft 304L and the cylindrical racks 306L and 314L to the gears 307L, 311L, 315L, and 318L attached to the third arms 107L and 108L. The gears 307L, 311L, 315L, and 318L are rotated by the driving of the rotation of the motor 301L, which causes the two contacts 109 attached to each gear 307L, 311L, 315L, 318L to move with the rotation of each gear 307L, 311L, 315L, 318L.
The two cylindrical racks 306L and 314L are rotatably supported by the second arm 106L through the support shafts 213L and 214L. The gear 307L engaged with the cylindrical rack 306L is fixed to a rotational shaft 308L supported rotatably by the third arm 107L. A fourth arm 3 L connecting the two contacts 109 is connected to the rotational shaft 308L. Thus, the gear 307L and the contacts 109 are integrally rotated about the rotational shaft 308L. The rotational shaft 308L is adapted to maintain the state in which the cylindrical rack 306L engages with the gear 307L. For example, the rotational shaft 308L may be provided with two flanges located above and below the third arm 107L to sandwich the third arm 107L.
The gears 311L, 315L, and 318L are similar in construction to the gear 307L. The gears 311L, 315L, and 318L are adapted to rotate integrally with the contacts carried by the respective gears 311L, 315L, and 318L about the respective gears 311L, 315L, and 318L. The gear 307L, the rotational shaft 308L, the fourth arm 309L, and the contacts 109 attached to the third arm 107L compose a contact unit 13 that makes contact with person's head 10.
As described above, the gear 307L and the contacts 109 of the contact unit 13 are integrally rotated about the rotational shaft 308L. In the contact unit 13, the two contacts 109 are rotated about the rotational shaft 308L. Alternatively, the two contacts 109 may be designed to move in a direction along a line connecting the two contacts 109 or to move in a direction orthogonal to the line.
The fourth arm 309L comprises a pair of branches 309Lb and a connection 309Lc for connecting the two branches 309Lb. Each branch 309Lb comprises the contact 109 at the end thereof. The two branches 309Lb are arranged in a V-shape and positioned in a symmetric manner with respect to the axis 309La. The two branches 309Lb are connected to the connection 309Lc at a vertex of the two branches 309Lb. The connection 309Lc is fixed to the rotational shaft 308L.
In the contact unit 13, the fourth arm 309L is configured to include an elastic body in at least one part of a region from the vertex of the branches 309Lb arranged in a V-shape to the contact 109. In the fourth arm 309L of the contact unit 13 shown in
In the contact unit 13, when the pushing force of the contact unit 13 applied on a person's head 10 becomes large, the distance between the vertex of the two branches 309Lb arranged in a V-shape and the person's head 10 becomes small and the distance between two contacts 109 becomes large. When the pushing force of the contact unit 13 applied on a person's head 10 becomes small with the two contacts 109 brought into contact with the person's head 10, the distance between the vertex of the two branches 309Lb arranged in a V-shape and the person's head 10 becomes large and the distance between two contacts 109 becomes small.
Thus, when the pushing force of the contact unit 13 on the person's head 10 is changed with the two contacts 109 brought into contact with the person's head 10, the distance between the vertex of the two branches 309Lb arranged in a V-shape and the person's head 10 is changed and the distance between two contacts 109 is changed. In the automatic hair washing system 100, the distance between two contacts 109 of the contact unit 13 can be adjusted by changing the pushing force of the contact unit 13 on the person's head 10, so that the washing of person's head 10 can be performed in an effective and reliable manner in accordance with the shape of the person's head 10.
When the contact unit 13 is moved along the person's head 10, the contacts 109 of the contact unit 13 are smoothly moved in an effective manner along the surface shape of the scalp 10a of the person's head 10. The contact 109 applies a shearing force to the scalp 10a by the movement thereof along the scalp 10a and applies a pressing force in a perpendicular direction to the scalp 10a by the pressing thereof against the scalp 10a. In the automatic hair washing system 100, the washing can be performed while slightly changing the position of the contact 109 in accordance with the shape of the person's head 10, so that the unwashed unit in the person's head 10 can be minimized. This ensures the hair washing system 100 to wash the entire person's head 10 without leaving an unwashed part thereof in a uniform and effective manner.
In the contact unit 13, when the contact 109 is pressed against a person's head 10, the axis of symmetry 309La of the fourth arm 309L carrying the contacts 109 is directed toward the center of the person's head 10. When the contact 109 is kept in contact with the person's head, the contact 109 is positioned on a line normal to the person's head 10.
When the contacts 109 are pressed against a person's head, the contacts 109 are forced in the direction of the center of the person's head 10 by elastic force of the branch 309Lb formed as a plate spring and the contacts 109 can be accurately positioned in accordance with the surface shape of the scalp 10a of the person's head 10. Thus, the person's head 10 can be smoothly washed in a effective manner.
The contact unit 13 may comprise an opening angle adjustment mechanism adapted to be capable of changing an opening angle between the pair of V-arranged branches 309Lb. The contact unit 13 ensures the opening angle between the pair of branches 309Lb to be elastically maintained in a predetermined angular range by the opening angle adjustment mechanism. The opening angle adjustment mechanism is preferably adapted to adjust the opening angle between the pair of branches 309Lb within an angular range from 60° to 150°.
In the contact unit 13 shown in
In the head care unit 40 comprising the contact units 13 so constructed, each of the third arms 107L and 108L rotatably supports the two contacts units 13. The third arms 107L and 108L are rotatably supported by the second arm. 106L through the respective support shaft 213L and 214L.
The second arm 106L is rotatably supported by the first arm 105L through the support shaft 212L. The second arm 106L moves in the direction approaching the person's head 10, when the first arm 105L rotates about the support shaft 212L in a direction approaching the person's head 10, which causes the contacts 109 carried by the third arm 107L and 108L to make contact with the person's head 10.
As shown in
When one of the two contact units 13 attached to the third arm 107L is pressed against the scalp 10a of the person's head 10, the two contacts 109 of the one contact unit 13 are moved away from each other in a direction orthogonal to a direction in which the two contacts 109 is pressed against the scalp 10a of the person's head 10. In
Furthermore, when the second arm 106L is moved in the direction approaching the person's head 10, the pushing force of the contact unit 13 applied on the person's head 10 is increased, which causes the third arm 107L to be tilted, as the one contact unit 13 is kept in contact with the scalp 10a of the person's head 10, as shown in
Back to
The contacts 109 may comprise a pressure sensor for detecting the contact thereof with the person's head 10 so that the driving of the motor 206L may be controlled based on a detection signal from the pressure sensor. The split unit 14 (for example, the third arm 107L and 108L of the split unit 14) may comprise a distance sensor for detecting a distance with the person's head 10 so that the driving of the motor 206L may be controlled based on a detection signal from the distance sensor.
In the head care unit 40, the second arm 106L rotatably supports the third arms 107L and 108L through the support shafts 213L and 214L and rotatably supports the two split units 14 in a longitudinal direction of the left washing unit 12L. The second arm 106L is rotatably supported by the first arm 105L through the support shaft 212L.
In the head care unit 40, when the second arm 106L is moved in a direction approaching the person's head 10, the third arm 107L is moved in the direction approaching the person's head 10, which causes one of the two split units 14 attached to the second arm 106L to be pressed against the scalp 10a of the person's head 10. Furthermore, when the second arm 106L is moved in the direction approaching the person's head 10, the other of the two split units 14 is pressed against the scalp 10a of the person's head 10. In this way, the respective contacts 109 of the two split units 14 on a side opposing the head support 11 thereof make contacts with scalp 10a of the person's head 10.
As above, the automatic hair washing system 100 according to the first embodiment comprises the contact unit 13 having a plurality of contacts 109 at the end thereof and having the wheels 307L, 311L, 315L and 318L with a center axis for rotating the plurality of contacts 109, the third arms 107L and 108L for holding the contact units 13 rotatably, the support shafts 213L and 214L for supporting the third arms 107L and 108L rotatably, the cylindrical racks 306L and 314L held to be movable in a direction parallel to the support shafts 213L and 214L and adapted to rotate the wheel 307L, 311L, 315L and 318L of the contact unit 13 by being moved in the above direction, and the motor 301L for moving the cylindrical racks 306L and 314L in a direction parallel to the support shafts 213L and 214L and for rotating the wheels 307L, 311L, 315L and 318L so as to oscillate the plurality of contacts 109. The wheels 307L, 311L, 315L and 318L serve as rotating wheels. The third arms 107L and 108L serve as tilt stages. The support shafts 213L and 214L serve as a tilt stage rotating shafts. The motor 301L serves as an oscillating actuator.
The head care system comprises a pushing mechanism for moving the support shafts 213L and 214L in a direction approaching person's head 10. The support shafts 213L and 214L are moved in the direction approaching person's head 10 by the pushing mechanism and the contacts 109 are oscillated by the driving of the motor 301L, so that the contacts 109 applies a pressing force on the person's head 10. The pushing mechanism is constructed by the motor 206L, the gears 207L and 208L, the first arm 105L, and the second arm 106L.
Thus, the scalp and hair of person's head 10 can be washed in an effective and reliable manner in accordance with the shape of the person's head 10 in any shape of person's head. According to the arrangement, in addition to the reliable washing of the person's head 10, the usage of water, shampoo and the like can be reduced, and the amount of unclean water for use in the washing can be reduced.
The head care unit 40 comprises two third arms rotatably supporting the contact units 13, but is not limited to such arrangement, may comprise three or more third arms. As above, the head care unit 40 comprises a plurality of third arms. This makes it possible to wash a wide range of person's head 10 and wash person's head 10 in an effective manner.
In the head care unit 40, the contacts units 13 provided on opposite sides of the cylindrical racks 306L and 314L are horizontally positioned. This makes it possible to thin the head care unit 40 in a thickness direction thereof and make the head care unit 40 smaller.
Furthermore, as shown in
The water system valve 216 comprises an input port connected to a water system supplying unit (not shown), so that cold water or hot water can be supplied in the water system valve 216 from the water system supplying unit. The washing solution system valve 217 comprises an input port connected to a mixing unit 220 for mixing a washing liquid and a compressed air, so that the foam washing solution, which are formed by mixing a washing liquid from the washing liquid supplying unit 222 for supplying the washing liquid such as shampoo and a compressed air in the mixing unit 220, can be supplied in the washing solution system valve 217. The conditioner system valve 218 comprises an input port connected to a conditioner supplying unit 221, so that the conditioner (e.g., rinse) from the conditioner supplying unit 221 can be supplied in the conditioner system valve 218.
In the automatic hair washing system 100, at least one of water, foam washing solution and conditioner can be ejected through a plurality of nozzles 110 mounted on the pipes 111L and 111R by appropriately controlling the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218.
The water system supplying unit and the water system valve 216 constructs a water supplying part for supplying cold water or hot water to the washing units 12L and 12R. The washing liquid supplying unit 222, the mixing unit 220 and the washing solution system valve 217 constructs a washing solution supplying part for supplying the washing solution to the washing units 12L and 12R. The conditioner supplying unit 221 and the conditioner system valve 218 constructs a conditioner supplying part for supplying the conditioner to the washing units 12L and 12R.
In the automatic hair washing system 100, two drain outlets 101b are formed in the bottom of the housing 101a of the bowl 101. The water and the like used for washing is discharged from the drain outlets 101b. The drain outlet 101b is connected to a drain pipe (not shown), so that the water and the like can be discharged outside the system 100 through the drain pipe for effluent treatment.
The bowl 101 has a cutout 101c for supporting a person's neck. The bowl 101 is provided with a support body 112 for supporting the back of the person's head 10. The support body 112 is designed to move up, down, left and right for positioning. The support body 112 can be positioned based on the position of person's head 10 detected by a position detecting means such as a camera for detecting the position of person's head 10.
The support body 112 is preferably positioned so that the support shafts 104L and 104R of the washing units 12L and 12R are located near person's ear. The straining force applied on person's neck can be suppressed by driving the washing units 12L and 12R about the location near person's ear. The support body 112 may be designed to wash the back of person's head 10 supported by the support body 112.
The support columns 102L and 102R arranged within the bowl 101 is designed that the support column 102L and 102R move in the axial direction of the support shafts 104L and 104R coupled to the support columns 102L and 102R. This makes it possible to adjust the distance between the person's head 10 and the arm base 103L and 103R in accordance with the size of the person's head 10 supported by the support body 112.
The bowl 101 is provided with a removable hood 113 for preventing water, shampoo and the like from spattering out of the system 100 during the washing, the hood 113 being adapted to be openable and closable. The hood 113 is preferably made of transparent material so as to give the washed person feelings of pressure and apprehension as little as possible during the washing.
As shown in
The attachment of the cover 115 to the contacts 109 prevents water, shampoo and the like, from attaching to the contacts 109, or prevents dirt from attaching to the contacts 109. When the cover 115 becomes dirty, the cover 115 is replaced. This makes it possible to keep the contact portions of the contacts 109 with the person's head 10 clean. The cover 115 may be replaced every time a person to be washed is changed. This makes it possible to wash the person's head 10 while always keeping the contact portions of the contacts 109 with the person's head 10 clean.
In the automatic hair washing system 100, the person's head 10 is washed with a water shield 510 attached to the person's head 10.
As shown in
The guard 510a of the water shield 510 is positioned to prevent water and the like from entering from a region of the person's scalp and hair to a region of the person's face 10b. The guard 510a prevents water and the like used for washing from entering the region of the person's face 10b beyond a curve 510d of the guard 510a in contact with the person's head 10 as a boundary line. The guard 510a is rotatably supported by a holding part 510e fixed to the ear cover 510b.

The water shield 510 is designed so that the region of person's hair 10c is remained open when the water shield 510 is mounted on person's head 10. Thus, the washing of person's hair 10c is performed without the interruption of the water shield 510. The open region of person's hair 10c ensures a space of easily washing person's head 10 when person's head 10 being washed by moving the washing units 12L and 12R.
The water shield 510 so constructed is mounted on person's head 10. This makes it possible to prevent water and the like from entering to person's face 10b in washing person's head 10, and hence wash person's head 10 comfortably.
When detaching the water shield 510 from person's head 10, the guard 510a is moved from a position shown in
The automatic hair washing system 100 comprises a control device 700 for comprehensively controls operation of the entire automatic hair washing system 100, as described later. The control device 700 can independently drive the washing units 12L and 12R. The control device 700 controls various operations such as operations of the motors 201L and 201R for rotating the washing units 12L and 12R about the support shafts 104L and 104R, the motors 206L and 206R for rotating the washing units 12L and 12R about the arm shafts 209L and 209R, and the motor 301L for rotating the contacts 109.
The automatic hair washing system 100 according to the first embodiment, in addition to being used as an system for automatically washing person's head 10, can be used as an system for automatically massaging person's head 10 by the contact 109 when water, shampoo and the like are not ejected through the nozzle 110.
As described above, the automatic hair washing system 100 according to the first embodiment comprises the bowl 101 having the head support 11 for supporting person's head 10, the left washing unit 12L and the right washing unit 12R, the motors 201L, 203L, 204L, 201R, 203R, and 204R, and the control device 700 for controlling the driving of the motors 201L, 203L, 204L, 201R, 203R and 204R. The washing units 12L and 12R are arranged with the head support 11 interposed therebetween, and the support shafts 104L and 104R thereof are attached to the bowl 101. The motors 201L, 203L, 204L, 201R, 203R and 204R rotate the washing units 12L and 12R about the support shafts 104L and 104R thereof. The each washing unit 12L or 12R has a plurality of split units 14 in the longitudinal direction of the washing units 12L or 12R. Each split unit 14 comprises a plurality of contacts 109 on the side opposing the head support 11.
As a result, the left and right washing units 12L and 12R are arranged with the head support 11 interposed therebetween. This makes it possible to wash person's hair in a safe and effective manner by the left and right washing unit 12L and 12R without a straining force applied on person's neck.
The definition of the operating direction of the automatic hair washing system 100 and the like will now be described with reference to
As shown in
In
Similarly for the right washing unit 12R of the automatic hair washing system 100, the arm base 103R, the first arm 105R, the second arm 106R, the third arms 107R and 108R, the plurality of contacts 109, and the like are collectively referred to as “right arm 114R” when seen from the support shaft 104R. The plurality of contacts 109 attached to the third arms 107R and 108R are referred to as “contact group R”, and the rotating direction is similarly defined.
In the following description, “push-rotating in phase” means that the left arm 114L and the right arm 114R always perform push-rotating in the same direction (pushing direction or release direction). The “push-rotating in reverse phase” means that the left arm 114L and the right arm 114R always perform push-rotating in the opposite direction. The “swing-rotating in phase” means that the left arm 114L and the right arm 114R always swing in the same direction (direction towards front side or back side of head 10). The “swing-rotating in reverse phase” means that the left arm 114L and the right arm 114R always swing in the opposite direction. When the left and right arms 114L and 114R swing in reverse phase, the sum of the angle positions of the swing-rotating of the arms 114L and 114R always is a value equal to a maximum angle (130°). Furthermore, when comparing the left and right contact groups L and R, the “knead-rotating in phase” means that the contact groups L and R always perform knead-rotating in bilaterally symmetric movement. The “knead-rotating in reverse phase” means that the contact groups L and R always perform knead-rotating in point symmetric movement. Furthermore, when comparing the fourth arms 309L, 310L, 317L, and 320L, the “knead-rotating in phase” means that the fourth arms to be compared always perform knead-rotating in the same direction. The “knead-rotating in reverse phase” means that the fourth arms to be compared always perform knead-rotating in the opposite direction. When the fourth arms to be compared perform knead-rotating in reverse phase, the sum of the angle positions of the knead-rotating always is a value equal to a maximum angle (60°).
The control device 700 of the automatic hair washing system 100 includes arm swing angle control sections 701L and 701R, arm pushing angle control sections 702L and 702R, and contact group angle control sections 703L and 703R. The arm swing angle control sections 701L and 701R, the arm pushing angle control sections 702L and 702R, and the contact group angle control sections 703L and 703R are all arranged for each of left and right arms 114L and 114R. The left arm swing angle control section 701L controls the swing-rotating angle of the left arm 114L. The right arm swing angle control section 701R controls the swing-rotating angle of the right arm 114R. The left arm pushing angle control section 702L controls the push-rotating angle of the left arm 114L. The right arm pushing angle control section 702R controls the push-rotating angle of the right arm 114R. The left contact group angle control section 703L controls the knead-rotating angle of the contact group L of the left arm 114L.

Furthermore, the control device 700 of the automatic hair washing system 100 includes an operating section 707 for accepting the operation input of the person. The operating section 707 is, for example, a touch panel type operating section, and has a function of displaying various types of operation states of the automatic hair washing system 100. The control device 700 of the automatic hair washing system 100, however, may include a display section for displaying the various types of operation states of the automatic hair washing system 100, separate from the operating section 707.
Furthermore, the control device 700 of the automatic hair washing system 100 includes a system control section 708. The system control section 708 comprehensively manages and controls each section (arm swing angle control sections 701L and 701R, arm pushing angle control sections 702L and 702R, contact group angle control sections 703L and 703R, water system valve control section 704, washing solution system valve control section 705, conditioner system valve control section 706, and operating section 707).
The system control section 708 includes an operation receiving unit 708E for processing the information of the operation input from the operating section 707, a display control unit 708F for controlling the display of various types of operation states in the operating section 707, and a storage unit 708I for storing various types of information input to the system control section 708. The system control section 708 includes a valve opening/closing command generating unit 708G for commanding the opening/closing of the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218, and a safety managing unit 708H for checking and managing the various safeties.
The arm swing angle control sections 701L and 701R control the driving of the corresponding motors 201L and 201R according to an angle command value generated by an angle command generating unit 708A of the system control section 708. The arm pushing angle control sections 702L and 702R control the driving of the corresponding motors 206L and 206R according to the angle command value generated by the angle command generating unit 708A of the system control section 708. The contact group angle control sections 703L and 703R control the driving of the corresponding motors 301L and 301R according to the angle command value generated by the angle command generating unit 708A of the system control section 708.
Specifically, the arm swing angle control sections 701L and 701R are configured to compare the angle command commanded by the angle command generating unit 708A and the rotation angle of the corresponding motors 201L and 201R, and supply the current corresponding to the error of the compared ones to the motor. The arm pushing angle control sections 702L and 702R are configured to compare the angle command commanded by the angle command generating unit 708A and the rotation angle of the corresponding motors 206L and 206R, and supply the current corresponding to the error of the compared ones to the motor. The contact group angle control sections 703L and 703R are configured to compare the angle command commanded by the angle command generating unit 708A and the rotation angle of the corresponding motors 301L and 301R and supply the current corresponding to the error of the compared ones to the motor.
The configuration of the left and right arm swing angle control sections 701L and 701R is similar to each other. The configuration of the left and right arm pushing angle control sections 702L and 702R is similar to each other. The configuration of the left and right contact group angle control sections 703L and 703R is similar to each other.
In
The control of the push-rotating angle of the left arm 114L will now be described. The control of the push-rotating angle of the right arm 114R is performed similar to the left arm 114L, and thus the detailed description thereof will be omitted.
A dual control system is configured for the control of the push-rotating angle of the left arm 114L. The first control system is a general angle command system that does not depend on the value of the pressure sensor 211L. This system is a system that outputs a command value θ1PLref generated by the angle command generating unit 708A to the left arm pushing angle control section 702L as a command value θPLref. The second system is a system that outputs a command value θ2PLref generated by the calculation based on the pressure sensor 211L to the left arm pushing angle control section 702L as a command value θPLref.
In
First, the pressure control calculating unit 708C has a table 901L that holds the values of the push-rotating angle θPL of the left arm 114L with respect to the swing-rotating angle θSL of the left arm 114L for the time when the contact group L of the left arm 114L is pushed against the head 10 at predetermined pushing force. One example of the table 901L is shown in
The pressure control calculating unit 708C also has a table 902L that holds the values indicated by the pressure sensor 211L in a state where the contact group L is separated from the head 10 for a predetermined plurality of combinations of the swing-rotating angle θsL of the left arm 114L and the push-rotating angle θPL. This is to respond to the influence of gravity on the output value of the pressure sensor 211L being changed by the position of the left arm 114L. Specifically, the pressure sensor 211L is subjected to the influence of weight of the members from the pressure sensor 211L to the head 10 since the pressure sensor 211L is configured to detect the stress applied on the head 10 through the second arm 106L, the third arms 107L and 108L and the other members. The degree of the influence changes according to the position (swing-rotating angle θsL and push-rotating angle θPL) of the left arm 114L. Therefore, correction needs to be made such that the influence of the gravity, which is applied on the members interposed between the pressure sensor 211L and the head 10, exerted on the output value of the pressure sensor 211L is excluded in accordance with the combination of the swing-rotating angle θsL and the push-rotating angle θPL. The table 902L is thus used. One example of the table 902L is shown in
In
The control system in a case where the control system switching section 903L is switch-controlled to a sign B side in
First, the comparator 905L compares the pushing force command PLref with the “stress PL applied on the head 10 of the left arm 114L” detected by the pressure sensor 211L and corrected by a weight correcting section 904L to obtain a pushing force error. A first control calculating section 906L amplifies an error signal obtained by the comparator 905L at a predetermined gain. A stabilization compensator 907L arranged to stabilize the control system generates a command value θPFBLref that becomes the base of an angle command value θ2PLref, based on the output of the first control calculating section 906L. The stabilization compensator 907L is configured by an integrator and achieves stabilization of a series of pushing control systems.
The weight correcting section 904L calibrates and outputs the value of the pressure sensor 211L based on the table 901L. In other words, the weight correcting section 904L calculates an offset value of the pressure sensor 211L corresponding to the current position of the left arm 114L based on the combination of the swing-rotating angle θSL of the left arm 114L and the push-rotating angle θPL of the left arm 114L reported from the state variable managing unit 708B, and the value of the table 901L corresponding to the relevant combination. The offset value is then divided with the current value of the pressure sensor 211L and output.
A second control calculating section 908L calculates a command value θPFFLref serving as a target value of the push-rotating angle θPL of the left arm 114L in a case where the left arm 114L makes contact with the head 10, based on the swing-rotating angle θSL of the left arm 114L reported from the state variable managing unit 708B and the value of the push-rotating angle θPL of the table 902L corresponding to the swing-rotating angle θSL. The system flow control unit 708D adds the command value θPFBLre and the command value θPFFLref by an adder 909L, and outputs the value obtained by the addition to the left arm swing-rotating angle control section 702L as a command value θ2PLref of the push-rotating angle of left arm 114L.
Therefore, the pushing force of the contact group L applied on the head 10 is controlled to match the commanded pushing force command θLref. The command value θPFBLref is a rotating angle control operation amount by the feedback system and enhances the robustness of the entire control system. The command value θPFFLref is a rotating angle operation amount by an open feed forward system, and improves the responsiveness by the feedback system.
The control of the push-rotating angle of the right arm 114R is also configured with a dual control system, similar to the control of the push-rotating angle of the left arm 114L. Each control system of the right arm 114R is constructed similar to each control system of the left arm 114L. The detailed description on the control of the push-rotating angle of the right arm 114R is thus omitted.
The control device 700 of the automatic hair washing system 100 so constructed cooperatively controls the swing-rotating angle and the push-rotating angle of the left arm 114L and the right arm 114R, the knead-rotating angle of the contact group L and the contact group R, as well as the opening/closing of the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218 with the system flow control unit 708D based on an operation input of the person received by the operation receiving unit 708E. Such cooperative control realizes an automatic washing operation of the person's head 10 in the automatic hair washing system 100.
The control operation of the swing-rotating and the push-rotating of the left arm 114L and the right arm 114R, as well as the knead-rotating of the contact group L and the contact group R by the control device 700 of the automatic hair washing system 100 will be hereinafter described.
First, an example shown in
As previously described above, the swing-rotating angle θSL of the left arm 114L and the swing-rotating angle θSR of the right arm 114R operate to substantially match each command value θSLref and θSRref. This operation will be described using the timing diagram of

Therefore, in the operation example shown in
In
One example of a cooperative control of the swing-rotating, the push-rotating, and the knead-rotating will now be described for the left arm 114L.
First, an example shown in
As described above, the swing-rotating angle θSL and the push-rotating angle θPL of the left arm 114L, and the knead-rotating angle θEL of the contact group L operate to substantially match each command value θSLref, θPLref, and θELref.
During time 0 to time t24(1), the left arm 114L waits at the position of swing-rotating angle 0° and push-rotating angle 0°. In other words, the left arm 114L is positioned on the back side of the head 10 and is waited in a state released from the head 10. Thus, the person can securely entrust the head 10 to the automatic hair washing system 100. Meanwhile, the contact group L is positioned at an initial position of 0°.
During time t24(1) to time t24(2), the left arm 114L is swing-rotated to the angle position of 130° towards the front side of the head 10 while maintaining the arm push-rotating angle at 0° and the knead-rotating angle of the contact group L at 0°. In this case, a state in which the contact group L is distant from the head 10 can be maintained since the push-rotating angle is maintained at 0° Therefore, the left arm 114L can be safely swing-rotated to the front side of the head 10 without the contact group L reversely stroking the hair of the head 10.
Time t24(2) to time t24(3) is the waiting time of the swing-rotating. During this waiting period, the control mode switching section 903L switches the control loop to the reference symbol B side in
After the waiting time until time t24(3) is finished, the left arm 114L is swing-rotated towards the back side of the head 10 while pushing the contact group L against the head 10 with the instructed pushing force as the push-rotating angle is adjusted by the function of the control loop. Meanwhile, the contact group L reciprocates between the knead-rotating angle of 0° and 60° at a substantially constant period.
Thereafter, the left arm 114L reciprocates between the back side (angle position of 0°) and the front side (angle position of 130°) of the head 10 by being swing-rotated while pushing the contact group L, which is knead-rotated at a substantially constant period, against the head 10 with the instructed pushing force.
The entire head 10 thus can be kneaded and washed while acting the massaging operation by the contact group L on the head 10. In this case, the water washing, shampoo washing, and rinse washing can be realized by appropriately instructing the opening/closing of the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218.
An example shown in
As described above, the swing-rotating angle θSL and the push-rotating angle θPL of the left arm 114L, and the knead-rotating angle θEL of the contact group L substantially match each command value θSLref, θPLref, and θELref.
The operation from time 0 to time t25(3) is similar to the operation from time 0 to time t24(3) in
From time t25(3) to time t25(4), the left arm 114L is swing-rotated towards the back side of the head 10 while pushing the contact group L against the head 10 with the instructed pushing force as the push-rotating angle is adjusted by the function of the control loop. Meanwhile, the contact group L is operated to reciprocate between the knead-rotating angle of 0° and 60° at a substantially constant period.
At time t25(4), the left arm 114L is swing-rotated to the backside (angle position of 0°) of the head 10, and then the swing-rotating of the left arm 114L is once waited until time t25(5). Meanwhile, the control mode switching section 903L switches the control loop to the reference symbol A side in
Similar to the operation from time t25(1) to time t25(2), the left arm 114L is swing-rotated to the front side (angle position of 130°) of the head 10 while maintaining the arm push-rotating angle at 0° and the knead-rotating angle of the contact group L at 0° from time t25(5) to time t25(6). In this case, a state in which the contact group L is distant from the head 10 can be maintained since the push-rotating angle is maintained at 0°. Therefore, the left arm 114L can be safely swing-rotated to the front side of the head 10 without the contact group L reversely stroking the hair of the head 10.
In the operation example shown in
An example shown in
An example shown in
As described above, the swing-rotating angle θSL and the push-rotating angle θPL of the left arm 114L, and the knead-rotating angle θEL of the contact group L operate to substantially match each command value θSLref, θPLref, and θELref.
After a short waiting time from time t27(4) to time t27(5), the left arm 114L is swing-rotated while linearly reducing the swing-rotating angle by a predetermined angle (e.g., about 20°) from time t27(5) to time t27(6). After a relatively small swing-rotating, the left arm 114L once stops the swing-rotating and waits from time t27(6) to time t27(7). After time t27(7), the left arm 114L repeats the swing-rotating of the predetermined angle and the once stopping (waiting state) of the swing-rotating until the angle position of the swing-rotating reaches the position of 0°.
At time t27(5), the pushing control system of the left arm 114L is turned ON. After time t27(5), predetermined pushing force Pa (e.g., pressure of 5N) is instructed in the pushing control system of the left arm 114L from time t27(5) to time t27(6) in which the left arm 114L is swing-rotated by a predetermined angle. Pushing force Pb (e.g., pressure of 10N) greater than the pushing force Pa is then instructed in the pushing control system of the left arm 114L from time t27(6) to time t27(7) in which the swing-rotating of the left arm 114L is in the waiting state.
According to the operation example shown in
An example shown in
As described above, the swing-rotating angle θSL and the push-rotating angle θPL of the left arm 114L, and the knead-rotating angle θEL of the contact group L operate to substantially match each command value θSLref, θPLref, and θELref.
After a short waiting time from time t28(2) to time t28(3), the left arm 114L is swing-rotated towards the back side while linearly reducing the swing-rotating angle by a predetermined angle (e.g., abut 20°) from time t28(3) to time t28(4), and period from time t28(4) to time t28(5) is a short waiting time in which the swing-rotating is once stopped. From time t28(5) to time t28(6), the left arm 114L is swing-rotated in the opposite direction (direction of returning to front side) while linearly increasing the swing-rotating angle by a predetermined angle (e.g., abut 10°), and period from time t28(6) to time t28(7) is a short waiting time in which the swing-rotating is once stopped. After time t28(7), the left arm 114L repeats a series of operations of sequentially carrying out the swing-rotating towards the back side, the once stopping of the swing-rotating (waiting state), the swing-rotating in the direction of returning to the front side, and the once stopping of the swing-rotating (waiting state) until the angle position of the swing-rotating reaches the position of 0°.
At time t28(3), the pushing control system of the left arm 114L is turned ON. After time t28(3), predetermined pushing force Pc (e.g., pressure of 5N) is instructed in the pushing control system of the left arm 114L from time t28(3) to time t28(4) in which the left arm 114L is swing-rotated towards the back side. The instructed value of the pushing force in the pushing control system of the left arm 114L is switched to pushing force Pd (e.g., pressure of 10N) greater than the pushing force Pc from time t28(4) to time t28(5) in which the swing-rotating of the left arm. 114L is once stopped. From time t28(5) to time t28(6) in which the left arm 114L is swing-rotated to returning to the front side, the instructed value of the pushing force in the pushing control system of the left arm 114L is maintained at the pushing force Pd (e.g., pressure of 10N). Furthermore, from time t28(6) to time t28(7) in which the swing-rotating of the left arm 114L is once stopped, the instructed value of the pushing force in the pushing control system of the left arm 114L is again switched to the pushing force Pc (e.g., pressure of 5N). The switching of the instructed value of the pushing force is similarly performed after time t28(7) in accordance with the timing of switching the operation related to the swing-rotating described above.
The knead-rotating angle of the contact group L is controlled to change from 0° to 60° from time t28(3) to time t28(4) in which relatively small pushing force Pc (e.g., 5N) is instructed in the pushing control system. The knead-rotating angle of the contact group L is controlled to change from 60° to 0° from time t28(5) to time t28(6) in which relatively large pushing force Pc (e.g., 10N) is instructed in the pushing control system.
According to the operation example shown in
One example of a cooperative control of the swing-rotating, the push-rotating, and the knead-rotating has been described above for the left arm 114L, but similar cooperative control can be performed for the right arm 114R. Various washing operations can be provided by arbitrarily combining the similar operation of the right arm 114R to the operation of the left arm 114L described above. In this case, variety of combinations can be realized by synchronizing or shifting the operation phases of the left and right arms 114L and 114R. Various operations other than the operation examples described above can be adopted for each operation of swinging, push-rotating, and knead-rotating. For instance, an operation in which the arms 114L and 114R push-rotate so as to switch at short intervals between the state in which the plurality of contacts 109 are in contact with the head 10 and the state in which the contacts 109 are separated from the head 10 may be adopted. In this case, the massage operation like lightly tapping the head 10 at short intervals can be realized.
A system operation flow managed by the system control section 708 will now be described.
When the control device 700 is started, a calibration step S201 is first executed. In the calibration step S201, the tables 902L (see
In the calibration step S201, the values of the pressure sensors 211L and 211R are measured for every combination of the swing-rotating angle and the push-rotating angle without the head 10 inserted in the bowl 101, and the tables 902L and 902R are created based on the measurement values. The specific measuring operation is as described above. The obtained tables 902L and 902R are used to make a correction such that the influence of the gravity with respect to the members interposed between the pressure sensor 211L and 211R and the head 10 exerted on the output value of the pressure sensor 211L and 211R is excluded in the subsequent steps. In other words, the offset values corresponding to the various positions of the arms 114L and 114R are calculated based on the values of the tables 902L and 902R.
In a mode selecting operation confirming step S202, whether or not one of the hair-wash mode, the massage mode, and the end mode is selected with the operation by the person is determined. The hair-wash mode is a mode in which the opening/closing of the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218 is controlled to perform washing. The massage mode is a mode in which the head 10 is massaged with the left and right arms 114L and 114R and the contact groups L and R. The end mode is a mode in which the system operation of the control device 700 is ended.
If confirmed that the selecting operation of one of the modes is performed in the mode selecting operation confirming step S202 (“YES” in step S202), the process proceeds to the next step.
In a next hair-wash mode selection confirming step S203, whether or not the mode selected by the person is the hair-wash mode is determined. If the selection of the hair-wash mode (“YES” in step S203) is confirmed according to such determination, the hair-wash mode to be described later is executed. If confirmed that the mode selected by the person is the mode other than the hair-wash mode in the hair-wash mode selection confirming step S202 (“NO” in step S203), the process proceeds to a massage mode selection confirming step S204.
In the massage mode selection confirming step S204, whether or not the mode selected by the person is the massage mode or the end mode is determined. If the selection of the massage mode (“YES” in step S204) is confirmed according to such determination, the massage mode to be described later is executed. The system operation is ended if the selection of the end mode (“NO” in step S204) is confirmed.
The hair-wash mode will now be described.
In the hair-wash mode, the necessary confirming operation is first executed before the person's head 10 is inserted in the bowl 101 in a first safety confirming step S205. Specifically, in the step S205, it is confirmed whether an attachment is worn on the person's head 10. More specifically, for example, presence/absence of attachments such as head accessories (e.g., hairpins, hair bands, etc.) in the hair of the person's head 10 is confirmed, and the person is called to attention to remove the attachments if there are any attachments. Whether or not the water shield visor 510 shown in
In the first safety confirming step S205, the confirmation on the presence/absence of attachments such as head accessories and the confirmation on the attachment of the water shield visor 510 are performed, for example, by a detection of the attachment or the water shield visor 510 by a camera. If a communicator such as a IC tag is mounted on the water shield visor 510, the attachment of the water shield visor 510 can be confirmed by the wireless communication with the communicator. Furthermore, information for calling the attention of the person to remove the attachment or to attach the water shield visor 510 may be notified to the person by being displayed on the touch panel type operating section 707 or a separately arranged display section as visual information or by being output from an audio device as audio information.
In a head receiving step S206, a preparation operation of inserting the person's head 10 to the bowl 101 is executed. Specifically, in the step S206, the left and right arms 114L and 114R are arranged at positions for receiving the head 10 on the support body 112. More specifically, the left and right support columns 102L and 102R are slidably moved so that the spacing between the support column 102L supporting the left arm 114L and the support column 102R supporting the right arm 114R are spread to a maximum. In the head receiving step S206, the left and right arms 114L and 114R operate such that the push-rotating angle is 0°. The contact groups L and R are thereby arranged spaced apart from the head 10 at a maximum. In the head receiving step S206, the left and right arms 114L and 114R also operate such that the swing-rotating position is the position (angle position of 0°) on the backside of the head 10.
The left arm 114L and the right arm 114R operating in such manner are in a state the spacing in between is opened to a maximum, and are positioned on the bottom side of the bowl 101. Therefore, the person's head 10 is safely placed (received) in the bowl 101 without being inhibited by the left and right arms 114L and 114R.
Furthermore, in the head receiving step S206, when the insertion of the head 10 in the bowl 101 is confirmed, the width adjustment between the left and right support columns 102L and 102R and the position adjustment of the support body 112 in accordance with the shape and size of the head 10 are executed. The confirmation on the insertion of the head 10 is performed based on the detection by various sensors. After the adjustment operation in accordance with the shape and the like of the head 10 is completed, the process proceeds to the next scanning step S207.
In the scanning step S207, the tables 901L and 901R described above are acquired and stored in the storage unit 708I. As described above, the tables 901L and 901R hold the value of the push-rotating angle with respect to the swing-rotating angle of each arm 114L and 114R in a case where the contact group L and R of the arm 114L and 114R is pushed against the head 10 at predetermined pushing force.
In the scanning step S207, the push-rotating angle θPL is scanned while gradually increasing the swing-rotating angle θSL and θSR of each arm 114L and 114R from 0° with the left and right arms 114L and 114R pushed against the head 10 at a substantially constant pressure. The value of the push-rotating angle θPL with respect to each value of the swing-rotating angle θSL, is acquired by scanning in such manner, and the tables 901L and 901R are created based on the acquired value.
A washing operation step S208 is then executed. As shown in
In the warm-up step S301, the preparation operation to become a state in which a hot water of an appropriate temperature can be supplied is executed. Specifically, the water system valve 216 is opened by a slight amount and then waited until the hot water becomes an appropriate temperature with the hot water supplied from a water heater (not shown) connected to the automatic hair washing system 100 being flowed by a small amount. The water remaining in the pipes 111L and 111R from the previous washing operation and the like thus can be pushed out. The cold water is thus avoided from suddenly ejecting on the person's head 10 thus causing the person to feel a sense of discomfort.
In the warm-up step S301, the temperature of the hot water supplied from the water heater is preferably detected with a temperature sensor arranged at an appropriate location so that the hot water of an appropriate temperature can be detected. In the washing operation step S208, a step of discharging water, washing solution or the like remaining in the pipes 111L and 111R may be provided before the warm-up step S301 or at the end of the washing operation step S208. The water and the washing solution remaining in the pipes 111L and 111R thus can be more reliably discharged. In this case, a drain valve may be arranged at an appropriate location of the automatic hair washing system 100.
After the warm-up step S301 is finished, the water washing step S302 is executed.
In the water washing step S302, hot water is ejected from the plurality of nozzles 100 so as to be poured to the head 10 while the left and right arms 114L and 114R are swung. Specifically, the left and right arms 114L and 114R are first swing-rotated to the front side (angle position of 130°) of the head 10 while maintaining the push-rotating angle at the angle position of 0° (release state). The water system valve 216 is then opened while maintaining the swing-rotating angle of the arms 114L and 114R on the front side (angle position of 130°) of the head 10, and the hot water is ejected from a plurality of nozzles 110 of the pipes 111L and 111R to the hair of the head 10. In this case, the opening degree of the water system valve 216 is set to be gradually widened so that a great amount of hot water is not suddenly ejected on the head 10. The left and right arms 114L and 114R are reciprocated and swing-rotated over plural times in the angle range from 0° to 130°. The hot water is thereby ejected on the entire head 10 and the hot water soaks into the hair.
Furthermore, in the water washing step S302, the hair is kneaded and washed by ejecting the hot water towards the head 10 while operating, in a composite manner, the swing-rotating angle and the push-rotating angle of the left and right arms 114L and 114R, and the knead-rotating angle of the contacts L and R, as described above. As shown in
After the water washing step S302 is finished, the shampoo step S303 is executed.
In the shampoo step S303, the washing liquid is ejected from the plurality of nozzles 110 so as to be poured to the head 10 while the left and right arms 114L and 114R are swung. Specifically, the left and right arms 114L and 114R are first swing-rotated to the front side (angle position of 130°) of the head 10 while maintaining the push-rotating angle at 0°. The washing solution system valve 217 is then opened with the swing-rotating angle of the arms 114L and 114R maintained at the position (angle position of 130°) on the front side of the head 10, and the washing liquid such as shampoo is ejected from the plurality of nozzles 110 of the pipes 111L and 111R to the hair of the head 10. As previously described, in the automatic hair washing system 100, the washing solution is formed into a mousse form by mixing the diluted washing liquid, in which the commercially available shampoo is diluted with water, and the compressed air in the mixing unit 220, and then the washing solution in the mousse form is ejected from the nozzle 110.
In this case, the opening degree of the washing solution system valve 217 is set to be gradually widened so that a great amount of washing solution is not suddenly ejected on the head 10. The left and right arms 114L and 114R are reciprocated and swing-rotated over plural times in the angle range from 0° to 130°, so that the washing solution is applied on the entire head 10. In the shampoo step 303, the left and right arms 114L and 114R are desirably operated in phase, as shown in
The massage washing step S304 is then executed. In the massage washing step S304, the plurality of contacts 109 are brought into contact with the head 10 by performing the push-rotating of the left and right arms 114L and 114R in the direction of approaching the head 10, and the head 10 is kneaded and washed by swinging the left and right arms 114L and 114R while performing the massage operation by the plurality of contacts 109. Specifically, the swing-rotating angle and the push-rotating angle of the left and right arms 114L and 114R and the knead-rotating angle of the contact groups L and R are operated, in a composite manner, as shown in
After the massage washing step S304 is finished, the rinsing step S305 is executed.
In the rinsing step S305, the water system valve 216 is opened, and the swing-rotating angle of the push-rotating angle of the left and right arms 114L and 114R and the knead-rotating angle of the contact groups L and R are operated, in a composite manner, while ejecting the hot water from the nozzles 110, similar to the water washing step S302. In the rinsing step S305, the pushing control system of the left and right arms 114L and 114R is first turned OFF to apply hot water in a release state (open state) and roughly wash off the washing solution. The pushing control system is thereafter turned ON, and the contact groups L and R are reciprocated for knead-rotating to efficiently rinse the head 10.
As shown in
After the rinsing step S305 is finished, the water dripping step S306 is executed.
In the water dripping step S306, the water system valve 216 is closed, and the ejection of hot water from the nozzles 110 is stopped. The left and right arms 114L and 114R are reciprocated and swing-rotated with the knead-rotating angle of the contact groups L and R fixed. Specifically, as shown in
After the water dripping step S306 is finished, the conditioner step S307 is executed.
In the conditioner step S307, the left and right arms 114L and 114R are first swing-rotated to the position (position of 130°) on the front side of the head 10 while maintaining the push-rotating angle in the release state (open state). The conditioner system valve 218 is then opened with the arms 114L and 114R stopped on the front side (angle position of 130°) of the head 10, and the conditioner such as rinse is ejected from the plurality of nozzles 110 of the pipes 111L and 111R to the hair of the head 10.
In this case, the opening degree of the conditioner system valve 218 is set to be gradually widened so that a great amount of conditioner is not suddenly ejected on the head 10. The left and right arms 114L and 114R are then reciprocated and swing-rotated over plural times in the angle range from 0° to 130°, so that the conditioner is applied on the entire head 10. In the conditioner step S307, the left and right arms 114L and 114R are desirably operated in phase, as shown in
Furthermore, the conditioner system valve 218 is closed at the end of the conditioner step S307, and the ejection of the conditioner from the nozzles 110 is stopped. As shown in
After the conditioner step S307 is finished, the rinsing step S308 similar to the rinsing step S305 and the water dripping step S308 similar to the water dripping step S306 are executed, sequentially. The rinsing time in the rinsing step S308 following the conditioner step S307 is preferably set to be shorter than the rinsing step S305 following the shampoo step S303 in order to avoid the conditioner effect from reducing caused by excessive rinsing. When using the conditioner that does not need to be rinsed, the rinsing step S308 and the water dripping step S309 after the conditioner step S307 may be omitted.
A second safety confirming step S209 shown in
Returning back to
In an interruption confirming step S210, whether or not an interrupting instruction of the washing operation by the operation of the user or the forcible interrupting instruction in the second safety confirming step S209 is made is confirmed during the washing operation step S208. If either one of the interrupting instruction is confirmed (“YES” in step S210), an interruption processing step S211, to be described later, is executed, and the overall operation is terminated after a head release step S215 to be described later and a pipe washing step S216 to be described later. If the interrupting instruction is not confirmed (“NO” in step S210), the process proceeds to a washing operation completion confirming step S212.
In the washing operation confirming step S212, whether each step of the warm-up step S301, the water washing step S302, the shampoo step S303, the massage washing step S304, the rinsing step S305, the water dripping step S306, the conditioner step S307, the rinsing step S308, and the water dripping step S309 in the washing operation shown in
If the completion of the final step (water dripping step S309 shown in
The interruption processing step S211 will be described. In the interruption processing step S211, the swing-rotating operation and the push-rotating operation of the left and right arms 114L and 114R and the knead rotating operation of the contact groups L and R are first stopped, and the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218 are all closed. When stopping the push-rotating operation, the control mode switching section 903L and 903R is forcibly switched to the reference symbol A side of
The head release step S215 will be described. In this step S215, the left and right arms 114L and 114R are arranged at positions for separating the head 10 away from the support body 112 so as to facilitate letting the head 10 out of the bowl 101. Specifically, the swing-rotating operation and the push-rotating operation of the left and right arms 114L and 114R and the knead-rotating operation of the contact groups L and R are stopped, and the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218 are all closed, similar to the interruption processing step S211. When stopping the push-rotating operation, the control mode switching section 903L and 903R is forcibly switched to the reference symbol A side of
Thus, similar to the head receiving step S206, the left arm 114L and the right arm 114R are positioned on the bottom side of the bowl 101 with a spacing in between. The operation of the person to remove the head 10 outside the bowl 101 can be safely performed.
When confirmed that the head 10 is outside the bowl 101 in the head release step S215, the next pipe washing step S216 is executed. The confirmation that the head 10 is outside the bowl 101 can be detected with various sensors.
In the pipe washing step S216, the water system valve 216 is opened, so that the conditioner and the like remaining in the pipes 111L and 111R can be washed away.
Thus, when performing the head washing operation the next time, the conditioner and the like remaining in the pipes 111L and 111R can be prevented from being ejected on the person's head 10 first. Furthermore, the conditioner and the like remaining in the piping 219 can be prevented from hardening, so that clogging of the piping 219 can be prevented.
After the pipe washing step S216 is finished, all operations of the hair-wash mode are terminated.
The massage mode will now be described.
In the massage mode, the presence/absence of attachments such as a hairpin or a hair band in the hair of the person's head 10 is confirmed in the third safety confirming step S217, and the person is urged to remove the attachment if there is any attachment. The specific operation is similar to the first safety confirming step S205 in the hair-wash mode other than that the attachment confirmation of the water shield visor 510 is not necessary.
In the head receiving step S218, the operation similar to the head receiving step S206 in the hair-wash mode is executed.
In the following scanning step S219, the operation similar to the scanning step S207 in the hair-wash mode is executed.
After the scanning step S219 is completed, a massage operation step S220 is executed.
As shown in
In the massage mode, the water system valve 216, the washing solution system valve 217, and the conditioner system valve 218 are all closed.
Returning back to
In the interruption confirming step S222, whether or not interrupting instruction of the massage operation by the operation of the person during the execution of the massage operation step S220 or the forcible interrupting instruction by the fourth safety confirming step S221 is made is confirmed. If either one of the interrupting instruction is confirmed (“YES” in step S222), an interruption processing step S223, to be described later, is executed, and the overall operation is terminated after the head release step S227, to be described later. If the interrupting instruction is not confirmed (“NO” in step S222), the process proceeds to a massage operation completion confirming step S224.
In the massage operation confirming step S224, whether or not each step of the slow in step S401, the massage step S402, and the slow out step S403 in the massage operation shown in
If the completion of the final step (slow out step S403 shown in
The interruption processing step S223 will now be described. In the interruption processing step S223, the swing-rotating operation and the push-rotating operation of the left and right arms 114L and 114R, and the knead-rotating operation of the contact groups L and R are first stopped. When stopping the push-rotating operation, the control mode switching sections 903L and 903R are forcibly switched to the reference symbol A side of
The head release step S227 will now be described. In the head release step S227, the swing-rotating operation and the push-rotating operation of the left and right arms 114L and 114R, and the knead-rotating operation of the contact groups L and R are first stopped, similar to the interruption processing step S223. When stopping the push-rotating operation, the control mode switching sections 903L and 903R are forcibly switched to the reference symbol A side of
Thus, the left arm 114L and the right arm 114R are positioned on the bottom side of the bowl 101 with a spacing in between, similar to the head receiving step S218. The person can thus safely carry out the operation of taking the head 10 out of the bowl 101.
After the head release step S227 is completed, the entire operation of the massage mode is terminated.
As described above, according to the automatic hair washing system 100, the left arm 114L and the right arm 114R including the contact groups L and R positioned on the left and the right of the head are arranged. The swing-rotating angle and the push-rotating angle of the left and right arms 114L and 114R and the knead-rotating angle of the contact groups L and R, as well as the water system valve, the washing solution system valve, and the conditioner system valve can be controlled in a composite manner. The washing operation thus can be safely executed without placing a strain on the person's neck. Moreover, not only the washing, but the head massage can also be executed.
The control operation of the knead-rotating angles θEL and θER of the left and right contact groups L and R will be further described with reference to
As described above, the contact groups L and R are basically controlled to reciprocately rotate over the entire angle range (angle range from 0° to 60°) of the knead-rotating angles θEL and θER during the knead-rotating operation. However, if the push-rotating angles θPL and θPR of the arms 114L and 114R are large, the ends of the left and right arms 114L, and 114R may become very close. Thus, the contacts 109 of the left and right contact groups L and R may interfere with each other at the central part of the head 10 in the lateral direction thereof if the basic control is constantly performed with respect to the knead-rotating angles θEL and θER. In order to avoid such interference of the contacts 109, the knead-rotating angles θEL and θER are controlled in the following manner as necessary.
In the state shown in
In order to resolve the above problem, the angular range of the knead-rotating angles θPL and θER is limited to a reduced range when the push-rotating angles θPL and θPR are a predetermined angle or more. The limited angular range of the knead-rotating angles θEL and θER is set to a range where the interference of the contact 109 at the right end of the left arm section 601L and the contact 109 at the left end of the right arm section 601R can be avoided. The limited angular range of the knead-rotating angles θEL and θER may be a predetermined fixed value, or may be a variable value set smaller the greater the push-rotating angles θPL and θPR. The kneading operation can be realized while avoiding the interference of the contacts 109 at the central part of the head 10.
In this control, the angular ranges of the knead-rotating angles θEL and θER of both the left and right arm sections 601L and 601R are equally limited in accordance with the push-rotating angles θPL and θPR of both the left and right arm sections 601L and 601R. However, various other configurations may be adopted for the limitation of the angular range of the knead-rotating angles θEL and θER. For instance, the angular range of both left and right knead-rotating angles θEL and θER or the knead-rotating angle θEL (θER) of one arm section 601L (601R) may be limited in accordance with the push-rotating angle θPL (θPR) of one arm section 601L (601R), so that the control and the structure can be simplified.
However, the swing-rotating is in phase at the timing the arm sections 601L and 601R pass each other even if the left and right arm sections 601L and 601R are swing-rotated with the phases shifted. Thus, at this timing, the contacts 109 may interfere with each other at the central part of the head 10 depending on the magnitude of the push-rotating angles θPL and θPR.
Therefore, even when the left and right arm sections 601L and 601R swing with the phase shifted, the angular range of the knead-rotating angles θEL and θER may be limited at the timing when the swinging of the left and right arm sections 601L and 601R becomes substantially in phase, that is, the timing when the difference in the swing-rotating angles θSL and θSR becomes a predetermined angle or less. This can realize the kneading operation so as to avoid the interference of the contacts 109 at the central part of the head 10 even when the left and right arm sections 601L and 601R during swinging pass each other.
Specifically, in this control, the angular ranges of the knead-rotating angles θEL and θER of both the left and right arm sections 601L and 601R are equally limited when the difference in the swing-rotating angles θSL and θSR of the left and right arm sections 601L and 601R is a predetermined angle or less. However, various other configurations may be adopted for the limitation of the angular range of the knead-rotating angles θEL and θER. For instance, the angular range of the knead-rotating angle θEL (θER) of only one arm section 601L (601R) may be limited in accordance with the difference in the left and right swing-rotating angle θSL and θSR, so that the control and the structure can be simplified. The angular ranges of the knead-rotating angles θEL and θER may be limited in accordance with not only the difference in the left and right swing-rotating angles θSL and θSR but also push-rotating angles θPL and θPR, as in the control described with reference to
