[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-24331 Summary of the Invention [Problem to be solved by the invention]

[0004] However, because the physique of each person receiving treatment varies, and the size and shape of their heads vary, face seals alone may not be able to prevent water leakage. Inside the hood, hot and cold water is ejected from multiple nozzles, and ideally, all of the hot and cold water ejected from the nozzles should hit the head. However, for example, if the head is relatively small, the ejected hot and cold water may cross the head and hit the hood or face seal, resulting in water leakage.

[0005] The present disclosure has been proposed in view of the above-mentioned circumstances, and provides a seal that can prevent water leakage regardless of individual differences in the person being treated. Do The object is to provide a component and an automatic hair washing device. [Means for solving the problem]

[0006] In order to achieve the above object, the seal according to the present disclosure Do The component is provided in a hair washing space of the automatic hair washing device, formed by covering the bowl portion on which the head of the person to be treated is placed with a hood portion, and is located near a face seal portion that seals the boundary between the head side and face side of the person to be treated when the head of the person to be treated is placed in the hair washing space, and is located at the destination of water discharged from a nozzle portion located in the hair washing space.

[0007] Seal according to the present disclosure Do The members are characterized in that they are configured as a pair on the left and right sides of the head of the person being treated, and are movable in a direction toward or away from the head.

[0008] Seal according to the present disclosure Do The member has a soft member that comes into contact with the head of the person to be treated, and the soft member is detachable.

[0009] Seal according to the present disclosure Do The member is characterized in that it is attachable to and detachable from a detachable part of the automatic hair washing device.

[0010] Seal according to the present disclosure Do The member is characterized in that it is slidable relative to the detachable portion and is stopped by frictional force.

[0011] Seal according to the present disclosure Do The member is characterized in that it has a first water-tight portion of the face seal portion that faces the neck seal portion that seals around the neck of the patient, and a second water-tight portion that protrudes away from the first water-tight portion toward the opposite side of the neck seal portion from the first water-tight portion.

[0012] Seal according to the present disclosure Do The member is characterized in that the second waterproof portion extends from the upper end of the first waterproof portion, and the first waterproof portion is attached to and detached from the detachable portion.

[0013] The automatic hair washing device according to the present disclosure is Do It is characterized by having a component. [Effects of the Invention]

[0014] For example, if the patient's head is relatively small or the top of the head is narrow, the hot water discharged from the nozzle may cross the head and hit the face seal, resulting in leakage from the boundary between the head and face. Do The member is provided in the hair washing space of the automatic hair washing device, which is formed by covering the bowl part on which the head of the person to be treated is placed with the hood part, and is located near the face seal part that seals the boundary between the head side and the face side of the person to be treated when the head of the person to be treated is placed in the hair washing space, and is located at the destination of water discharged from the nozzle part located in the hair washing space. Do The member blocks the hot and cold water that does not hit the head just before the face seal, so the hot and cold water does not reach the face seal and does not leak from the face seal. Therefore, water leakage can be prevented regardless of individual differences in the person receiving treatment. [Brief explanation of the drawings]

When hot water hits the neck-side seal portion, it is ejected from the top of the patient's head toward the neck-side seal portion in a generally horizontal or generally downward direction, and the hot water is blocked by the first water-shielding portion. When hot water hits the face-side seal portion of the face seal portion that seals around the patient's face, it is ejected from the back of the patient's head toward the face-side seal portion in a generally upward direction, and the hot water is blocked by the second water-shielding portion. Therefore, water leakage can be prevented regardless of the direction from which water is ejected.

[0021] Seal according to the present disclosure Do The member has a second water shielding portion extending from an upper end of the first water shielding portion, and the first water shielding portion is attached to and detached from the detachable portion. The first water shielding portion also has the function of being attached to and detached from the detachable portion, and the first water shielding portion and the second water shielding portion are realized in an integrated and simple configuration.

[0022] The automatic hair washing device according to the present disclosure is Do Therefore, the above-mentioned seal Do The same effect occurs as with the components.

[0023] Hereinafter, an automatic hair washing device and a seal according to an embodiment of the present disclosure will be described. Do The components will be described with reference to the drawings. Figures 1 and 2 show the automatic hair washing device 1 according to this embodiment. In the following, the direction in which a person to be treated (not shown) lies down will be referred to as the front side, the opposite side will be referred to as the back side, the width direction when the front-to-back direction is the depth will be referred to as the right side and the left side, and the height direction of the automatic hair washing device 1 will be referred to as the upper side and the lower side (see Figure 1).

[0024] As shown in Figures 1 and 2, the automatic hair washing device 1 has a main body 2 that stands on its own on an installation surface, a bowl 4 on top of the main body 2 on which the head of the person to be treated is placed, and a hood 5 (not shown in Figure 2) that covers the top of the bowl 4. The hood 5 can be freely opened and closed. A hair washing space 7 is formed inside the space surrounded by the hood 5 and the bowl 4.

[0025] A treatment table (not shown) is placed in front of the main body front part 3, which is the front of the main body part 2. The person to be treated lies on the treatment table and places their head in the hair washing space 7. A face seal part 8 is formed at the boundary between the head side and face side of the person to be treated. Specifically, the face seal part 8 seals the edge of an opening 11 formed across the main body front part 3 and the hood front part 6, which is the front of the hood part 5. The face seal part 8 is composed of a concave neck seal part 9 formed at the upper end of the main body front part 3 and a concave face seal part 10 formed in the hood front part 6. The face seal part 8 is circular or approximately circular to match the shape of the opening 11. The neck seal part 9 is placed on the neck seal part 9, and the periphery of the neck is sealed. The face seal part 10 is placed around the periphery of the person to be treated and seals the periphery of the face. Therefore, the part of the head excluding the face (including the ears) is placed in the hair washing space 7, and the face is exposed to the outside.

[0026] Inside the bowl portion 4, there are a head support member 40 on which the head of the person to be treated is placed in the hair washing space 7, and a pair of left and right seals that are placed on the head in the hair washing space 7. Do 2 and 3, the bowl portion 4 is provided with at least a seal member 20 and an arch-shaped shower member 60 that discharges hot and cold water onto the head in the hair washing space 7. DoThe detachable part 12 to which the member 20 is attached and detached, a shower head 17 that is manually operated by the practitioner, and a hot and cold water stop valve 18 are installed, and a drain outlet 19 is formed at the bottom. The detachable part 12 is located on the front side of the neck seal part 9. The detachable part 12 is a member in which two plate-like parts 13 face each other with a gap 16 between them. The plate-like parts 14, 15 are arranged in an upright position, with the front plate part 14 on the near side larger than the rear plate part 15 on the rear side (in other words, the rear plate part 15 is smaller than the front plate part 14).

[0027] Here, seal Do The member 20, the head support member 40, and the shower member 60 will be described in order based on the drawings. Do The exterior of the member 20 is shown in FIGS. Do The operation of the member 20 is shown. Do Since the member 20 is symmetrical, the following is a description of the left seal. Do 1. Description of member 20, right seal Do The description of the member 20 is omitted.

[0028] As shown in Figures 4 to 10, the seal Do The member 20 is T-shaped (see, for example, FIG. 7) and has a soft member 33. The soft member 33 is detachable. Seal Do The member 20 is composed of a protruding piece 21, a first waterproof portion 23 extending downward from the lower end of the protruding piece 21, and a second waterproof portion 22 extending from the boundary between the protruding piece 21 and the first waterproof portion 23 in a direction away from the protruding piece 21 and the first waterproof portion 23. The protruding piece 21 is a plate-like piece extending upward and becomes thinner as it extends upward. The first waterproof portion 23 is a plate-like piece extending downward. The second waterproof portion 22 is a plate-like piece extending toward the rear.

[0029] seal Do A seal formed on the front surface of the member 20 by the protruding piece portion 21 and the first water-shielding portion 23 Do The front surface 24 is flat or generally flat. DoThe upper and rear surfaces of the member 20 are provided with a seal formed by the protruding piece portion 21 and the second water-shielding portion 22. Do The upper rear surface portion 25 curves from the protruding piece portion 21 to the second water-shielding portion 22, and has a gentle L-shape when viewed from the side (see FIG. 7). Do A seal formed on the underside and rear side of the member 20 by the second water impermeable portion 22 and the first water impermeable portion 23 Do The lower rear surface portion 26 has a right-angled or substantially right-angled L-shape when viewed from the side (see FIG. 7). Do Seal from front part 24 Do A spacer 32 (see FIG. 7) is attached across the lower rear portion 26. The spacer 32 is flat and can be freely deformed, and can be attached, detached, and replaced.

[0030] seal Do The seal on the left side of the member 20 Do The outer surface portion 27 has a linear shape extending from the protruding piece portion 21 to the first water-shielding portion 23 (see FIG. 8). Do The outer surface portion 27 is on the right side in the figure. Do The seal of the outer surface portion 27 Do A rib 29 is formed at the end of the upper rear surface portion 25 (see FIG. 4). The rib 29 protrudes upward. Seal Do The seal on the right side of the member 20 Do The inner surface portion 28 is inclined from the protruding piece portion 21 to the first water-shielding portion 23, and the sealing Do Away from the outer surface portion 27 (in other words, the seal Do The inner surface portion 28 extends from the first water-shielding portion 23 to the protruding piece portion 21, and the sealing Do Close to the outer surface 27. See Figure 8. Seal Do The inner surface portion 28 is on the left side in the figure.) A storage space 30 for storing a soft member 33 is formed inside the second waterproof portion 22 and the first waterproof portion 23, and a storage opening portion 31 communicating with the storage space 30 is provided in the sealing member 24. Do It is formed on the inner side surface portion 28. The accommodation opening portion 31 and the accommodation space 30 are L-shaped with a right angle or a substantially right angle when viewed from the side (see FIG. 7).

[0031] The soft member 33 is, for example, a cushion, rubber, gel, or the like, and is freely deformable. Therefore, when the soft member 33 is housed in the housing space 30, it is bent into an L-shape according to the shape of the housing space 30. When housed in the housing space 30, the soft member 33 forms a seal. Do The seal is formed longer than the width of the member 20. Do It protrudes from the inner surface portion 28. Of the protruding soft members 33, the first soft piece 34 is arranged on the same plane as the first water-shielding portion 23, and the second soft piece 35 is arranged on the same plane as the second water-shielding portion 22.

[0032] A seal constructed as described above Do The member 20 is attached to the detachable portion 12 in the bowl portion 4 as shown in Figures 11 and 12. Specifically, the seal Do The first waterproof portion 23 of the member 20 also functions as a detachable portion for the detachable portion 12, and is therefore sandwiched in the gap 16 of the detachable portion 12. Do When the member 20 is attached to the detachable portion 12, the first waterproof portion 23 faces the neck side seal portion 9 of the face seal portion 8, and the second waterproof portion 22 extends away from the first waterproof portion 23 toward the rear side, which is the opposite side of the neck side seal portion 9 relative to the first waterproof portion 23.

[0033] Next, seal Do The operation and effect of the member 20 will be described with reference to the drawings. Figures 13 to 16 show a cross-sectional side view of the automatic hair washing device 1, and illustrate the operation of the shower member 60 and the sealing of the shower member 60. Do The position of member 20 is shown.

[0034] 11 and 12, the head of the patient is placed on the head support member 40, and the therapist Do When the member 20 is grasped and pushed toward the head, the seal Do The member 20 moves in a direction toward the head. That is, before the head is placed on the head support member 40, the seal Do Since the member 20 is separated from the head, the seal is not formed when the head is placed. DoThe member 20 does not interfere (see FIG. 11). Do The member 20 is held in place by the frictional force between the detachable part 12 and the first water-shielding part 23 (spacer 32). Do By sliding the member 20, a seal Do The member 20 can be moved toward or away from the head, and when it stops sliding, the seal Do The member 20 remains in place. Do The member 20 has a simple structure and can be easily moved. After the head is placed, the seal is adjusted according to the size of the head. Do The member 20 is closer to the head, so the seal Do The member 20 is adjusted to the appropriate position. Do When handling the member 20, the protruding piece 21 can be gripped.

[0035] seal Do The member 20 is moved until the soft member 33 comes into contact with the head. Since the part that comes into contact is the soft member 33, there is little irritation to the skin. Do When the member 20 is in contact with the head, the first waterproof portion 23 is sandwiched in the gap 16 of the detachable portion 12, but a part of the first waterproof portion 23 protrudes from the detachable portion 12 toward the head and faces the neck seal portion 9. The second waterproof portion 22 is positioned behind the ear of the patient, and the protruding piece portion 21 is positioned below the earlobe. In this state, the seal Do The inner surface portion 28 is inclined upward from the first water-blocking portion 23 to the protruding piece portion 21 in a direction away from the face of the person receiving treatment, so that it does not come into contact with the ears or face. Therefore, pressure on the ears or face is prevented. Do When moving the member 20 in a direction away from the face, the practitioner can grasp the protruding piece 21 and hook their fingers on the rib 29, so that the seal is Do The member 20 can be easily moved.

[0036] As shown in Figures 13 to 16, shower member 60 rotates within a predetermined rotation angle range within hair washing space 7, moving back and forth around the head of the person to be treated and discharging hot and cold water toward the head. Do For example, if the head of the person to be treated is relatively small or the top of the head is narrow, the discharged hot and cold water will cross the head and head toward the face seal part 8. Do Since member 20 blocks the hot and cold water before it reaches face seal portion 8, the hot and cold water does not reach face seal portion 8 and does not leak from face seal portion 8. Therefore, water leakage can be prevented regardless of individual differences between the recipients. Specifically, when shower member 60 is located below and hot and cold water is discharged from the back of the recipient's head in a generally upward direction toward face-side seal portion 10 (see FIG. 13), the hot and cold water passes through second water-blocking portion 22, seal Do The hot and cold water is blocked by the lower rear surface portion 26, the second soft piece 35 of the soft member 33, etc. Also, when the shower member 60 is positioned approximately horizontally and is discharged in an approximately horizontal direction from the top of the head of the person to be treated toward the neck side seal portion 9 (see FIG. 15), the hot and cold water is blocked by the first water blocking portion 23, the seal Do Lower rear part 26, protruding piece part 21, seal Do The hot and cold water is blocked by upper rear surface portion 25, first soft piece 34 of soft member 33, etc. Furthermore, when shower member 60 is located generally upward and is discharged generally downward from the top of the head of the person to be treated toward neck side seal portion 9 (see FIG. 16), the hot and cold water is blocked by projecting piece portion 21, seal Do The water is blocked by the upper rear surface portion 25, the second soft piece 35, etc. Therefore, no matter what direction the water is discharged from, the seal Do The member 20 provides water insulation and prevents water leakage.

[0037] Also, seals Do The member 20 has a simple and integrated structure including the protruding piece 21, the second waterproof portion 22, and the first waterproof portion 23 (see FIGS. 4 to 10). Do The member 20 is removed from the detachable portion 12, so the seal Do The member 20 can be easily cleaned or replaced (see FIG. 3). DoSince it is detachable from the member 20, the soft member 33 can be easily cleaned or replaced (see Figures 9 and 10).

[0038] Next, the head support member 40 will be described with reference to the drawings. Figures 13 and 14 show a side cross section of the automatic hair washing apparatus 1 and illustrate the operation of the head support member 40. Figures 17 to 22 show the appearance and cross section of the head support member 40.

[0039] 13 and 14, the head support member 40 has a support main body 41 that supports the head of the person to be treated in the hair washing space 7, and a support base 46 that supports the support main body 41 so that it can swing. The support main body 41 swings back and forth relative to the support base 46. The support main body 41 and the support base 46 form a movement mechanism 50 (see FIGS. 21 and 22), and the movement mechanism 50 causes the support main body 41 to swing back and forth. Specifically, the movement mechanism 50 moves the support main body 41 to a support position that supports the head during automatic hair washing (FIG. 13), while during non-automatic hair washing, the support main body 41 moves to a separated position that is away from the top of the head and toward the neck of the person to be treated (FIG. 14). In the support position, the support body 41 is generally horizontal or has a posture with the rear end slightly pointing upward, and while moving from the support position to the separated position, the rear end of the support body 41 moves downward and the front end moves upward and forward toward the neck of the patient. At that time, the support body 41 swings in an arc between the support position and the separated position (see arrow 100 in FIG. 13 and arrow 101 in FIG. 14).

[0040] As shown in Figures 17 to 22, the support body 41 has a mesh part 42 that supports the back of the head of the patient, and a pair of mesh support parts 43 that support the left and right sides of the mesh part 42. The mesh shape of the mesh part 42 is arbitrary, for example, a honeycomb shape. The mesh support part 43 is a rectangular parallelepiped that is long from front to back. A slit 44 is formed on the underside of the mesh support part 43, and a connecting piece part 45 is located inside the mesh support part 43. The slit 44 leads to the connecting piece part 45. The mesh support parts 43 are arranged at a distance that is the same as the width of the patient's head or wider than the width of the head, and the mesh part 42 is stretched between the two mesh support parts 43.

[0041] The support base 46 has a plate-shaped base piece 47, a pair of plate-shaped base leg pieces 48 that rise from both ends of the base piece 47 at right angles to the base piece 47, and a base connecting piece 49 formed at the upper end of the base leg piece 48. The base leg piece 48 is curved in an arc upward and toward the rear. The base connecting piece 49 is passed through the slit 44 of the net support part 43 and connected to the connecting piece 45.

[0042] The support main body 41 has a rail portion 51 as the movement mechanism 50, while the support base 46 has an engagement protrusion 55 that engages with the rail portion 51 and a guide protrusion 56 that is guided by the rail as the movement mechanism 50. Specifically, the rail portion 51 is formed in the connecting piece portion 45 inside the net support portion 43. The rail portion 51 extends in the front-to-rear direction and curves in an arc downward or is bent downward. Two notches 52 that are cut out toward the upper side are formed in the rail portion 51. One of the notches 52 is a support notch 53 and is formed at the front end of the rail portion 51. Meanwhile, the other notch 52 is a non-support notch 54 and is formed in the middle of the rail portion 51.

[0043] The engagement protrusion 55 and the guide protrusion 56 are attached to the side surfaces of the base connecting piece 49 and are spaced apart in the front-to-rear direction. The engagement protrusion 55 is formed at the front end of the base connecting piece 49. The guide protrusion 56 is formed at the rear end of the base connecting piece 49. In the support position, the engagement protrusion 55 engages with the support notch 53, while no protrusions engage with the non-support notch 54 (see Figure 21). On the other hand, in the separated position, the engagement protrusion 55 engages with the non-support notch 54, while no protrusions engage with the support notch 53 (see Figure 22).

[0044] Next, the function and effect of the head support member 40 will be described with reference to the drawings.

[0045] In FIG. 13, when the practitioner grasps the support main body 41 in the support position and pushes it forward (arrow 100 in the same figure), the movement mechanism 50 operates, and the support main body 41 moves to the separated position. In FIG. 14, in the separated position, the support main body 41 moves away from the top of the head of the person to be treated, leaving space on the back and top of the head, so the head is uncovered. Therefore, when washing hair by hand after automatic hair washing, the practitioner can move their hands in the space, making hair washing easier. Note that in the separated position, the front end of the support main body 41 is located above and forward, so the area near the nape of the neck of the person to be treated may remain on the mesh portion 42. Even in this case, space is left on at least a portion of the back of the head (the part of the back of the head closer to the top of the head), making hair washing easier.

[0046] The rail portions 51 of the net support portion 43 are curved in an arc downwards or bent downwards (see Figures 21 and 22), so that when the engaging protrusions 55 of the support base portion 46 are engaged with the rail portions 51, the support main body portion 41 swings in an arc or bends by moving along the rail portions 51. This leaves space on the back and top sides of the head of the person being treated, allowing the practitioner to wash hair in an open space.

[0047] At the support position, the engaging protrusions 55 engage with the support notches 53, causing the support main body 41 to stop and maintaining an appropriate posture for supporting the head of the user during automatic hair washing (see FIGS. 15 and 21). On the other hand, at the separated position, the engaging protrusions 55 engage with the non-support notches 54, causing the support main body 41 to stop and maintaining an appropriate posture for manually washing the user's head (see FIGS. 14 and 22).

[0048] Furthermore, since the part that directly supports the head is the mesh part 42, only a small part of the head is covered (see FIG. 17). This minimizes the area that interferes with hair washing with the automatic hair washing device 1. Because both sides of the mesh part 42 are supported and there is space below the mesh part 42, the mesh support part 43 and support base part 46 do not interfere with hair washing.

[0049] Next, the shower member 60 will be described with reference to the drawings. Shower member 60 is shown in FIGS.

[0050] As shown in Figures 23 and 24, the shower member 60 has an arch-shaped water flow pipe 61 and multiple nozzle members 63 attached to this water flow pipe 61. The left end of the water flow pipe 61 has a rotating shaft 62, and the right end is closed. The water flow pipe 61 has holes (not shown) formed at predetermined intervals, and the nozzle members 63 are attached to align with the holes. Therefore, hot and cold water flowing from the rotating shaft 62 and flowing through the water flow pipe 61 is supplied to each nozzle member 63.

[0051] Here, the nozzle member 63 will be described with reference to the drawings. Figures 25 to 33 show the appearance, cross section, and structure of the nozzle member 63. Note that the description based on Figures 25 to 33 will be based on the orientation shown in Figure 25. The orientation shown in Figure 25 is different from the orientation shown in Figure 1.

[0052] 25 to 27, the nozzle member 63 has an intake member 64, an upstream cover 65 and a downstream cover 66 that cover the intake member 64 from above and below, and a fixing cover 67 for fixing the upstream cover 65 to the water flow pipe 61. First, the internal structure of the nozzle member 63 will be described with reference to Figures 30 and 32, and then the external shape of each member will be described with reference to other drawings. Figures 30 and 32 show a cross section of the nozzle member 63.

[0053] As shown in Figures 30 and 32, a flow path through which hot and cold water flows is formed inside the nozzle member 63. The flow path is subdivided as it moves downstream. The flow path has a communication flow path section 84 at the most upstream side that communicates with the water flow pipe 61, a branch flow path section 85 that is connected to the downstream side of this communication flow path section 84 and widens as it moves downstream, and a plurality of water discharge flow path sections 86 that are connected to the downstream side of this branch flow path section 85. Each water discharge flow path section 86 has an air intake hole 87 that is connected to the outside.

[0054] The branch flow path section 85 has a flat space 88. The flat space 88 is long in the left-right direction and flat in the front-to-back direction. The left-to-right width of the flat space 88 gradually increases and the front-to-back thickness gradually decreases from the connecting flow path section 84 toward the downstream side. The branch flow path section 85 has a plurality of partitions 89, which divide the flat space 88 into a plurality of branch flow paths 92. The partitions 89 are composed of a central partition 90 formed approximately in the center of the branch flow path section 85 and side partitions 91 formed at positions spaced apart on the left and right sides of the central partition 90. The central partition 90 extends toward the downstream side, and the side partitions 91 extend toward the downstream side and the left and right sides, respectively. Two central flow paths 93 are formed between the central partition 90 and each of the side partitions 91, and two side flow path sections 94 are formed between each of the side partitions 91 and the inner wall 95 of the branch flow path section 85. Therefore, the flat space 88 is divided into four branch flow paths 93, 94 by each of the partitions 90, 91, and the flow path from the communication flow path section 84 to the discharge channel section 86 is divided into the four branch flow paths 93, 94 approximately evenly.

[0055] The discharge channel section 86 is formed narrower than each of the branch channels 93, 94 of the flat space 88. Each discharge channel section 86 is linear and arranged in parallel or approximately parallel fashion. Therefore, the discharge ports 99 of the discharge channel sections 86 face the same direction (upward in Figure 30) and are lined up in a row on the left and right. The number of discharge channel sections 86 is arbitrary, but is generally 10 to 20, which is more than the number of branch channels 92 (in other words, the number of branch channels 92 is less than the number of discharge channel sections 86).

[0056] The discharge channel section 86 has an upstream channel 96 connected to the downstream side of the branch channel section 85, a connecting channel 102 formed downstream of the upstream channel 96, a midstream channel 97 connected to the downstream side of the connecting channel 102, and a downstream channel 98 connected to the downstream side of the midstream channel 97. The upstream channel 96 is formed narrower than the branch channels 93, 94 of the flat space 88. The connecting channel 102 is formed wider than the upstream channel 96. The midstream channel 97 is formed wider than the upstream channel 96 and has the same or approximately the same diameter as the connecting channel 102. The downstream channel 98 is formed narrower than the midstream channel 97 and wider than the upstream channel 96. The channels 96, 102, 97, 98 are connected in a straight line.

[0057] The air intake hole 87 is formed in the connecting flow path 102 between the upstream flow path 96 and the midstream flow path 97. The air intake hole 87 opens in a direction perpendicular or approximately perpendicular to the water flow direction in the discharge water path portion 86. The inner diameter of the air intake hole 87 is the same as or approximately the same as that of the upstream flow path 96.

[0058] 26 and 27, the fixed cover 67 is a generally rectangular plate with a semicircular grip portion 81 on one side through which the water flow pipe 61 is passed. Screws 82 are passed through the four corners of the fixed cover 67.

[0059] The upstream cover 65 has an upstream cover main body 68 that is long in the left-right direction, a semicircular other-side gripping portion 69 connected to the lower part of the upstream cover main body 68, and a branch flow path portion 85 formed inside the upstream cover main body 68. An annular upstream cover edge portion 70 that extends upward from the outer periphery is formed at the upper end of the upstream cover main body 68, and an intake member mounting groove 71 to which the intake member 64 is attached is formed inside the upstream cover edge portion 70. The intake member mounting groove 71 communicates with the branch flow path portion 85. Gap-forming outer ends 72 are formed at both left and right ends of the upstream cover main body 68.

[0060] The intake member 64 is long in the left-right direction, has a plurality of upstream flow passages 96 formed on the inside, and has a plurality of intake holes 87 formed on the front and rear outer surfaces. Each intake hole 87 leads to a connecting flow passage 102 of each upstream flow passage 96. The upper end of the intake member 64 is formed with an annular intake member edge portion 73 extending upward from the outer periphery, and a downstream cover mounting groove portion 74 is formed inside this intake member edge portion 73, to which the downstream cover 66 is attached.

[0061] The downstream cover 66 has a downstream cover outer body portion 75 that is long in the left-right direction, a pair of support pieces 76 extending downward from the downstream cover outer body portion 75 and configured as a front-rear pair, and a downstream cover inner body portion 77 (see Figures 30 and 32) formed inside the downstream cover outer body portion 75, with a midstream flow path 97 and a downstream flow path 98 formed in the downstream cover inner body portion 77. An intake member mounting gap 78 (see Figures 30 and 32) to which the intake member 64 is attached is formed between the downstream cover outer body portion 75 and the downstream cover inner body portion 77. A screw hole 79 is formed in each support piece portion 76. Gap-forming inner ends 80 are formed on the inner surfaces of both left and right ends of the downstream cover outer body portion 75.

[0062] The intake member 64 is attached to the intake member attachment groove 71 of the upstream cover 65, thereby connecting the branch flow path portion 85 of the upstream cover 65 and the upstream flow path 96 of the intake member 64. In this state, the downstream cover inner main body portion 77 of the downstream cover 66 is attached to the downstream cover attachment groove 74 of the intake member 64, and the intake member edge portion 73 of the intake member 64 is attached to the intake member attachment gap 78 of the downstream cover 66, thereby connecting the connecting flow path 102 of the intake member 64 and the midstream flow path 97 of the downstream cover 66. Finally, the fixed cover 67 is attached to the lower part of the upstream cover 65 and the lower part of the downstream cover 66, and the screws 82 of the fixed cover 67 are fastened to the screw holes 79 of the downstream cover 66. At this time, the water flow pipe 61 is sandwiched between the other-side grip portion 69 of the upstream cover 65 and the one-side grip portion 81 of the fixed cover 67.

[0063] 25, 28, 29, 31, and 33, the components 64, 65, 66, and 67 are combined to form the nozzle component 63. The gap-forming outer end 72 of the upstream cover body 68 and the gap-forming inner end 80 of the downstream cover outer body 75 are not in close contact with each other, and a ventilation gap 83 is provided between them.

[0064] Next, the function and effect of the nozzle member 63 will be described with reference to the drawings.

[0065] When the pump built into the main body 2 or an external pump (not shown) is operated and hot water is supplied from the hot water storage tank (not shown), the hot water flows through the water flow pipe 61 into the nozzle member 63. The hot water passes through the connecting flow path 84, the branching flow path 85, and the water discharge path 86, and is discharged from the water discharge port 99 (see Figures 30 and 32). At this time, based on Bernoulli's theorem, air is drawn in through the ventilation gap 83 and the air intake hole 87, and the hot water mixed with air is discharged. The hot water contains a large number of fine air bubbles, and when the bubbles come into contact with the hair, they pop, simultaneously popping off dirt, thereby improving the cleansing effect. This results in a uniform hair wash finish. In particular, because the water discharge ports 99 of the water discharge path 86 face the same direction and are aligned in a row, the hot water with improved cleansing effect hits the entire head of hair when it is discharged from each water discharge port 99. Therefore, the hair wash result is even.

[0066] The partitions 90, 91 formed in the branch flow path section 85 divide the flow path from the communication flow path section 84 to the water discharge path section 86 into four branch flow paths 93, 94 approximately evenly (see Figure 30). Because the hot and cold water is diverted approximately evenly in each branch flow path 93, 94 before flowing into each water discharge path section 86, the water pressure in each water discharge path section 86 is also approximately uniform. Because there is little difference in water pressure between each water discharge path section 86, the force of the hot and cold water hitting the hair is also approximately uniform across the entire head of hair. This results in a more even wash. In addition to the uniform water discharge, the use of hot and cold water with a high cleansing effect that is mixed with air makes for an even more even wash.

[0067] In particular, in the branch channel section 85, the water is divided into four branch channels 93, 94, and each branch channel 93, 94 is divided into three or four water discharge channel sections 86. In other words, water pressure is not applied to all water discharge channel sections 86 at once, but rather the water is divided into multiple branch channels 93, 94 at each partition section 90, 91 and then water pressure is applied to multiple water discharge channel sections 86, so the pressure of the hot and cold water discharged is roughly uniform. Therefore, the hair washing finish is even.

[0068] In the water discharge channel section 86, the upstream channel 96 is narrower than the branch channels 93, 94 of the flat space 88, the connecting channel 102 is wider than the upstream channel 96, the midstream channel 97 is wider than the upstream channel 96 and has the same or approximately the same diameter as the connecting channel 102, the downstream channel 98 is narrower than the midstream channel 97 and wider than the upstream channel 96, and the air intake hole 87 opens in the connecting channel 102 between the upstream channel 96 and the midstream channel 97 in a direction perpendicular or approximately perpendicular to the water flow direction in the water discharge channel section 86 (see Figures 30 and 32). By being sucked in and passing through the channels 96, 97, 98, the hot and cold water has a high cleansing effect and is discharged at high pressure. This results in a consistent hair wash finish.

[0069] The nozzle member 63 is a combination of the components 64, 65, 66, and 67, allowing for easy assembly. It can also be disassembled for easy replacement and cleaning. The gap-forming outer end 72 of the upstream cover main body 68 and the gap-forming inner end 80 of the downstream cover outer main body 75 are not in close contact with each other, leaving a ventilation gap 83 between them (see Figures 30 and 33). Therefore, air can be drawn in even when covered by the components 64, 65, 66, and 67. In particular, because the air intake hole 87 is covered by the covers 6, 5, 66, and 67, it is possible to prevent the intrusion of chemicals such as coloring agents used in treatments or foreign matter into the air intake hole 87. Furthermore, uniform coverage of each air intake hole 87 also reduces the water pressure difference at each water outlet 99.

[0070] Shower member 60 rotates within a predetermined rotation angle range and moves back and forth within hair-washing space 7, moving around the head of the person being treated and spraying hot and cold water in a straight line toward the head, with the sprayed hot and cold water hitting the surface of the head at a right angle or nearly a right angle (see Figures 13 to 16). The hot and cold water hits the dense roots of the hair and the scalp with force, allowing for a proper hair wash.

[0071] Next, as other embodiments of the nozzle member 63, a nozzle member 263 according to a second embodiment and a nozzle member 363 according to a third embodiment will be described with reference to the drawings. Figure 34 shows a partial cross section of the nozzle member 263 according to the second embodiment, and Figure 35 shows a partial cross section of the nozzle member 363 according to the third embodiment. Note that the following mainly describes the configuration that differs from the nozzle member 63, and a description of the configuration that is the same as the nozzle member 63 will be omitted.

[0072] As shown in FIG. 34, the nozzle member 263 has the connecting flow path 202 and the midstream flow path 297 connected with a lateral offset. That is, the upstream flow path 296 and the connecting flow path 202 are aligned in a straight line, the midstream flow path 297 and the downstream flow path 298 are aligned in a straight line, and the upstream flow path 296 and the connecting flow path 202 are aligned with the midstream flow path 297 and the downstream flow path 298, but are offset from each other. This offset creates resistance to the water flow, thereby suppressing water pressure. Therefore, it is possible to adjust the water pressure according to the degree of offset. In addition, the pressure of hot and cold water discharged from each outlet 299 is roughly uniform. Note that the water pressure can also be adjusted by adjusting the water volume by controlling the pump's AC motor, inverter, and PWM (Pulse Width Modulation).

[0073] As shown in FIG. 35 , the nozzle member 363 has a step 303 formed at the boundary between the midstream flow path 397 and the downstream flow path 398, connecting the two flow paths 397, 398 in a stepped manner. That is, the midstream flow path 397 and the downstream flow path 398 are straight, cylindrical shapes, and the inner diameter of the downstream flow path 398 is smaller than the inner diameter of the midstream flow path 397. The step 303 is formed by the difference in the inner diameters of the flow paths 397, 398. This configuration ensures that the pressure of hot and cold water discharged from each spout 399 is roughly uniform. Similar to the nozzle member 263, the nozzle member 363 has a connecting flow path 302 and a midstream flow path 397 that are offset to the left and right and connected to each other. Note that the connecting flow path 302 and the midstream flow path 397 may be connected in a straight line, similar to the nozzle member 63.

[0074] <Seal Do Materials> In another embodiment according to the present disclosure, a seal Do The components are fixed and cannot be moved or removed. In other embodiments, there is no soft member. In another embodiment, the soft member is a seal. Do It is fixed to the component and cannot be removed. In another embodiment, only the protruding piece portion and the first water-shielding portion are provided, and the second water-shielding portion is not provided. In another embodiment, only the protruding piece portion and the second water-shielding portion are provided, and the first water-shielding portion is not provided. In another embodiment, only the first water shielding portion and the second water shielding portion are provided, and no protruding piece portion is provided. In another embodiment, the seal Do The parts are moved automatically by electricity. <Head support member> In another embodiment, the support body moves directly below the head, so that the spaced apart position is below the head. In another embodiment, the support body moves from the top of the head toward the rear. Therefore, the separated position is at the rear of the head. When the mesh part is separated from the rear of the head and a gap is formed between the mesh part and the rear of the head, hand washing is possible. In another embodiment, the rail portion does not have a notch. In this case, when the patient's head is placed on the mesh portion of the support body, the support body swings according to the posture of the head. Therefore, the head is supported in an appropriate position according to the posture, size, shape, etc. of the patient's head. In another embodiment, the support body is electrically and automatically moved to the support position or the spaced position. <Nozzle material> In another embodiment, the direction of the water outlet of the nozzle member is not constant. In another embodiment, the hot and cold water ejected from the nozzle member hits the surface of the head of the person to be treated at an arbitrary angle. In another embodiment, the position of the intake hole in the water discharge channel section is arbitrary. Another alternative embodiment does not have a divider. In another alternative embodiment, the nozzle member is formed as a single unit and cannot be disassembled. In another embodiment, the position of the gap between the upstream cover and the downstream cover is arbitrary.
