FIG. 11 is a schematic side view of the switching cylinder 51 shown in FIG. 10 viewed from another direction (a direction different from FIG. 10 by 90 °). 12 is a schematic top view of the switching cylinder 51 shown in FIG. 13 is a schematic bottom view of the switching cylinder 51 shown in FIG.

  The switching cylinder 51 is provided in a substantially cylindrical shape. On one end side of the switching cylinder 51 (upper end side in FIGS. 10 and 11), a notch 511 for determining the direction in which the liquid flows is provided. In addition, a pair of projecting pieces 512a and 512b are provided on the other end side (the lower end side in FIGS. 10 and 11) of the switching cylinder 51 so as to face each other.

  A flange portion 52 is integrally formed on the outer periphery of the switching cylinder 51. On the flange portion 52, three convex portions 521 having a substantially trapezoidal shape in a side view are arranged at equal intervals along the outer periphery of the switching cylinder 51. The three convex portions 521 are paired with three engaging grooves 223 (see FIGS. 17A to 17C described later) provided at equal intervals in the circumferential direction at the lower end of the rotating shaft portion 22. The function which switches the connection state (connection and non-connection) between 22 and the switching cylinder 51 is exhibited. Note that the engaging groove 223 is slightly larger than the convex portion 521, but its shape is substantially the same as the convex portion 521. Further, the flange portion 52 provided with the convex portion 521 and the engagement groove 223 provided on the end surface (lower end surface) of the rotation shaft portion 22 are also elements constituting the switching mechanism 50.

  The elements constituting the switching mechanism 50 also include a ratchet ring 53 disposed in the through hole 26a of the base portion 26 (see FIG. 5). FIG. 14 is a schematic side view showing the configuration of the ratchet ring 53 provided in the automatic hair washing apparatus 1 according to the embodiment of the present invention. FIG. 15 is a schematic top view of the ratchet ring 53 shown in FIG. FIG. 16 is a schematic bottom view of the ratchet ring 53 shown in FIG.

  The ratchet ring 53 is provided in a substantially disk shape. On the one end face 53a (upper end face in FIG. 14) side of the ratchet ring 53, a first opening 531 having a substantially circular shape in plan view is provided to form a recess. On the other end surface 53b (lower end surface in FIG. 14) side of the ratchet ring 53, a second opening 532 having a substantially circular shape in plan view is formed to form a recess. The ratchet ring 53 is formed with a substantially lemon-like through-hole 533 in plan view so as to penetrate these recesses. Near the outer periphery of the other end surface 53 b of the ratchet ring 53, three protrusions 534 having a substantially trapezoidal shape in side view are arranged at equal intervals in the circumferential direction. The three protrusions 534 engage with engagement holes 26b (three are provided at equal intervals in the circumferential direction) provided in the base portion 26 (see FIG. 5).

  Elements constituting the switching mechanism 50 include a compression coil spring 54 disposed between the flange portion 52 and the ratchet ring 53. Due to the urging force of the compression coil spring 54, the flange portion 52 provided integrally with the switching cylinder 51 is pressed toward the lower end of the rotating shaft portion 22.

  FIG. 17A, FIG. 17B, and FIG. 17C are schematic diagrams for explaining the operation of the switching mechanism 50 provided in the automatic hair washing apparatus 1 according to the embodiment of the present invention. In the state shown in FIG. 17A, for example, the rotation direction of the rotation shaft portion 22 starts to reverse from the first direction X1 to the second direction X2 or from the second direction X2 to the first direction X1. The previous state is assumed. As a state shown in FIG. 17B, for example, a state is assumed in which a little time has passed since the rotation shaft portion 22 reversed the rotation direction from the second direction X2 to the first direction X1. As a state illustrated in FIG. 17C, for example, a state in which a little time has passed since the rotation shaft portion 22 reversed the rotation direction from the first direction X1 to the second direction X2 is assumed.

  The first direction X1 is a direction in which the rotation shaft portion 22 rotates clockwise in FIG. Further, the second direction X2 is a direction in which the rotation shaft portion 22 rotates counterclockwise in FIG. In FIGS. 17A to 17C, schematic cross-sectional views showing the structure of the ratchet ring 53 and its surroundings are shown in a broken-line circle. A part of the base portion 26 is also shown in the broken circle for convenience of explanation.

  In the state shown in FIG. 17A, each convex portion 521 is fitted in each engaging groove 223, and the rotation shaft portion 22 and the switching cylinder 51 are connected to each other. The switching cylinder 51 is also connected to the ratchet ring 53 by fitting the projecting pieces 512a and 512b into the through holes 533 (see also FIGS. 10 to 16). The protrusion 534 of the ratchet ring 53 enters an engagement hole 26 b provided in the base portion 26.

  In the state shown in FIG. 17A, the liquid that is supplied from the joint portion 261 (see FIG. 5) and enters the hollow portion 22 a of the rotating shaft portion 22 almost passes through the switching cylinder 51. And most of the liquid that has passed through the switching cylinder 51 is supplied to one rotating pipe (any one of the three rotating pipes 23 a to 23 c) that exists at a position facing the notch 511. It will be.

  A case where the rotation shaft portion 22 rotates in the first direction X1 from the state shown in FIG. 17A will be described. When the rotation shaft portion 22 rotates in the first direction X1, each convex portion 521 and each engagement groove 223 maintain a meshed state due to their shapes. That is, the state where the rotation shaft portion 22 and the switching cylinder 51 are connected is maintained. For this reason, the switching cylinder 51 also rotates with the rotation of the rotation shaft portion 22. Therefore, when the rotation direction of the rotation shaft portion 22 is reversed from the second direction X2 to the first direction X1, the positional relationship between the switching cylinder 51 and the rotation pipes 23a to 23c does not change. That is, the switching of the ejection amount of the liquid ejected from the nozzle row 21L of each of the rotating pipes 23a to 23c does not occur due to the reversal of the rotating direction.

  When the rotation shaft portion 22 rotates in the first direction X1, the ratchet ring 53 connected to the switching cylinder 51 also rotates in the base portion 26 as shown in FIG. 17B. When the ratchet ring 53 rotates, the projection 534 comes out of the engagement hole 26b of the base 26, and the position of the ratchet ring 53 approaches the flange 52 while contracting the compression coil spring 54 as shown in FIG. 17B. In this state, when the rotation shaft portion 22 continues to rotate in the first direction X1 and reaches a position where the rotation direction is reversed (or in the vicinity thereof), the protrusion 534 is fitted into another engagement hole 26b. .

  Next, the case where the rotating shaft part 22 rotates in the second direction X2 from the state shown in FIG. 17A will be described. When the rotation shaft portion 22 rotates in the second direction X2, the rotation shaft portion 22 tries to slide up the inclined surface with respect to the convex portion 521 as shown in FIG. 17C. Along with this, the compression coil spring 54 contracts, and the switching cylinder 51 moves in a direction approaching the ratchet ring 53. The ratchet ring 53 is strongly pressed against the base portion 26 by the compression coil spring 54.

  As a result, the ratchet ring 53 and the switching cylinder 51 connected to the ratchet ring 53 try to stay in that position, and only the rotation shaft portion 22 continues to rotate until reaching the position where the rotation direction is reversed. At the position where the rotation direction is reversed (or in the vicinity thereof), the convex portion 521 and the engagement groove 223 return to the fitted state. For this reason, when the rotation shaft portion 22 rotates in the second direction X2 from the state shown in FIG. 17A, the positional relationship between the switching cylinder 51 and the rotation pipes 23a to 23c changes. When the rotation shaft portion 22 rotates by a predetermined amount, the rotation pipe facing the notch portion 511 of the switching cylinder 51 is shifted by one to become another rotation pipe. As a result, the nozzle row 21L that ejects a large amount of liquid is changed.

  FIG. 18 is a block diagram showing an electrical configuration of the automatic hair washing apparatus 1 according to the embodiment of the present invention. The automatic hair washing apparatus 1 includes a control unit 60 that can be configured by, for example, a microcomputer. The control unit 60 controls each unit of the apparatus according to the condition relating to the hair washing input to the operation unit 61. The operation unit 61 may be, for example, a button group or a touch panel provided on the apparatus main body, a button group or a touch panel provided on the remote controller, or the like. Examples of conditions relating to shampooing include the temperature of water to be jetted, the amount of water to be jetted, the type of liquid agent, the amount of liquid agent, the type of hair washing course, and the like.

  The controller 60 controls the operation of the first valve 43 and the second valve 44 that switch the amount of hot water supplied to the hair washing unit 20. Further, the control unit 60 operates a water supply pump 62 for supplying hot water stored in the hot water storage tank to the nozzle 21 and the hydraulic cylinder 30 in accordance with a hair washing course or the like input to the operation unit 61. Further, the control unit 60 operates a liquid agent supply pump 63 for supplying a liquid agent such as a shampoo liquid to the nozzle 21 according to the hair washing course or the like input to the operation unit 61.

  Furthermore, the control unit 60 controls the first three-way valve 48 and the second three-way valve 49 based on information (signals) obtained from the first limit sensor 64 and the second limit sensor 64, and The flow of the liquid supplied to the hydraulic cylinder 30 is switched. As the limit sensors 64 and 65, an optical sensor, a magnetic sensor, or the like may be used instead of a limit switch that is mechanically switched on and off.

  FIG. 19 is a schematic diagram showing the relationship between the person M to be washed and the automatic hair washing apparatus 1 when washing the hair using the automatic hair washing apparatus 1 according to the embodiment of the present invention. When performing hair washing using the automatic hair washing apparatus 1, the person M to be washed lies on his back on the bed 70 (stretcher or the like), for example, and the back of the head is supported by the support 71. In this state, the hair washing part 20 is arranged so that the rotation shaft part 22 faces the head P of the person M (the top of the head and its vicinity) where the hair is washed. Each of the rotary pipes 23a to 23c extending from the rotary shaft portion 22 is arranged along the head of the person M to be washed.

  At the time of shampooing, the rotating pipes 23 a to 23 c reciprocate within a range of a rotation angle of 130 ° (only an example) by the rotation of the rotation shaft portion 22. Furthermore, hot water is also sprayed onto the top of the head P of the person M to be washed by the shaft nozzle 222. For this reason, the person M who is shampooed can obtain a feeling that hot water is sprayed on the entire head. Further, since each of the rotating pipes 23a to 23c does not rotate 360 ° but reciprocates within a certain range, the possibility that the hair of the person to be washed M is entangled with the rotating pipes 23a to 23c and the like is reduced. it can.

  Since hot water is jetted from the plurality of nozzle rows 21L onto the head of the person M to be washed, the person M to be washed is stimulated from various directions at a time, and a comfortable hair washing feeling can be obtained. Further, the position of the nozzle row 21L from which a large amount of liquid is ejected and the position of the nozzle row 21L from which a small amount of liquid is ejected are appropriately changed by the action of the switching mechanism 50. For this reason, a sense of rhythm (strength) is given to hair washing, and a massage effect can be expected. Further, when the rotation direction of the rotation shaft portion 22 is reversed, the amount of hot water sprayed from the shaft portion nozzle 222 temporarily varies due to the structure of the hydraulic cylinder 30. This variation can also stimulate the head of the person M to be washed and expect a massage effect.

Moreover, since the hair washing part 20 is driven using the hydraulic cylinder 30, a reduction in running cost can be expected as compared with the case where a motor is used. Moreover, since the drainage from the hydraulic cylinder 30 is also jetted to the person M to be washed, the utilization efficiency of hot water in the hot water storage tank is good. Moreover, since the hot water supplied using the water supply pump 62 is used not only as the liquid ejected from the nozzle 21 but also for driving the hydraulic cylinder 30, the utilization efficiency of electricity is good.

<Others>

  The embodiment described above is merely an example of the present invention. The configuration of the embodiment described above may be changed as appropriate without departing from the technical idea of the present invention.

  For example, a mortar-shaped cover 28 as shown in FIGS. 21 and 22 may be attached to the rotating body 24 so as to cover the rotating pipes 23a to 23c of the automatic hair washing apparatus 1 described above. . FIG. 21 is a schematic side view for explaining an attachment example of the cover 28 that covers the rotating pipes 23a to 23c provided in the automatic hair washing apparatus 1 according to the embodiment of the present invention. FIG. 22 is a schematic front view for explaining an attachment example of the cover 28 that covers the rotating pipes 23a to 23c provided in the automatic hair washing apparatus 1 according to the embodiment of the present invention.

  As shown in FIG. 22, the nozzle row 21 </ b> L provided in the rotary pipes 23 a to 23 c is exposed from the surface of the cover 28 so that liquid can be ejected. Further, a part of the distal end side of the rotation shaft portion 22 and the shaft portion nozzle 222 are also exposed from the surface of the cover 28. When the cover 28 is attached in this way, it is possible to reduce the possibility that the hair of the person performing the hair washing will be entangled with the rotary pipes 23a to 23c.

  Note that a plurality of protrusions formed of, for example, silicon may be disposed on the surface of the cover 28 at an appropriate location so as to come into contact with the head of a person in a hair washing posture (see, for example, FIG. 19). A massage effect can be expected by rotating the cover 28 while the projection contacts the head. Such protrusions may be provided on the rotating pipes 23a to 23c depending on circumstances.

  Further, in the embodiment described above, in each nozzle row 21L, the rotating pipes 23a to 23c are curved so that the plurality of nozzles 21 are arranged along a curved line (for example, arranged in an arc shape). It was. However, the present invention is not limited to this configuration. A state in which a plurality of nozzles 21 are arranged along a curved line may be obtained by using a structure in which a plurality of straight pipes are connected. In some cases, the rotating pipe provided with the nozzle row 21L may be a single straight pipe.

  Moreover, in the automatic hair washing apparatus 1 shown above, you may provide suitably the hood for preventing that the liquid sprayed from the nozzles 21 and 222 splashes. The food may prevent the splashed liquid from being applied to the person performing the hair washing.
