Description

[Technical Field]

[0001] The present invention relates to a head immersion device used for scalp massage, etc. [Background technology]

[0002] Conventionally, hair salons and other beauty salons have shampoo bowls for washing the hair of patients. The patient places their head in the shampoo bowl, and the therapist performs the treatment from the side or the top of the head. Treatments performed in the shampoo bowl include, for example, shampooing and scalp massage, and depending on the treatment, can take anywhere from several tens of minutes to an hour. During treatments that require a long time, if the patient's neck directly hits the edge of the shampoo bowl, the patient may experience neck pain. Therefore, for example, the shampoo bowl-mounted pillow described in Patent Document 1 below (hereinafter referred to as the "Publicly Known Document 1 Invention") is attached to the edge of the shampoo bowl and acts as a cushion to prevent the patient's neck from directly hitting the edge of the shampoo bowl.

[0003] On the other hand, therapists have many other tasks to perform besides treatment, such as cleaning, tool maintenance, answering the phone, and confirming appointments. However, if therapists are tied up in a long treatment session, they are unable to perform other tasks during that time. Therefore, a treatment that is comfortable for the patient and allows the therapist to perform other tasks is required. One example of such a treatment is to continuously pour hot water over the patient's head or to continuously immerse the head in hot water (hereinafter referred to as "head immersion"). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Registered Utility Model No. 3185374 Summary of the Invention [Problem to be solved by the invention]

[0005] The invention of the above-mentioned publicly known document 1 is attached between the neck of the recipient and the edge of the shampoo bowl, so the position of the recipient's head relative to the bottom of the shampoo bowl is higher than when the invention is not used. In this case, even if hot water is filled in the shampoo bowl, the hot water overflows and flows over the edge of the shampoo bowl before the water level reaches the recipient's head, so the head is not submerged. Even if the water level could be raised without overflowing, it would require a large amount of hot water, which is not economical.

[0006] The present invention was proposed in light of the above-mentioned circumstances, and aims to provide a head immersion device that is comfortable for the patient and allows the therapist to perform other tasks without interfering with the treatment. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the head immersion device of the present invention comprises a tub main body attached to the inside of a shampoo bowl in which the person to be treated is to be treated, a pair of hollow rod-shaped members formed on the left and right sides of the tub main body and connected at their tips extending upward to the tub main body, and a water outlet connected to the lower part of the tips, wherein the rod-shaped members act as a flow path that sends hot water to the tips and from the tips downward to the water outlet, and the water outlet releases the hot water that is to be applied to the head of the person to be treated inside the tub main body in the form of a continuous curtain straight down, and the rod-shaped members can be tilted backward to adjust the position at which the hot water hits the head.

[0008] The head immersion device according to the present invention is characterized by having an adjustment mechanism for rotating the rod-shaped member to adjust the angle.

[0009] The head immersion device according to the present invention is characterized in that the water outlets formed in the water outlet section are linearly continuous from side to side.

[0010] The head immersion device according to the present invention is characterized in that the hair of the person to be treated is immersed in the tub main body.

[0011] The head immersion device according to the present invention is characterized in that the head of the person to be treated is placed on the rod-shaped member in a reclined position.

[0012] In addition, the head immersion device may be characterized by having a tub main body portion attached to the inside of a shampoo bowl in which the person to be treated is treated, which holds hot water for immersing the person's head, a flow path portion extending upward from the tub main body portion, and a water discharge portion connected to the tip of the flow path portion and discharging hot water to be applied to the person's head.

[0013] The head immersion device may be characterized in that the flow path section is configured as a pair on the left and right sides with the water discharge section at the center.

[0014] The head immersion device may be characterized in that the hot and cold water discharged from the water discharge portion is in the form of a curtain.

[0015] The head immersion device may be characterized in that the flow path section rotates so that the hot and cold water discharged from the water discharge section is positioned at a position that hits the head of the person being treated, or at a position that does not face the head of the person being treated.

[0016] The head soaking device may be characterized in that the bucket body is fitted with a drain outlet of the shampoo bowl.

[0017] The head immersion device may be characterized in that the tub main body stores hot and cold water from a water supply device other than the water discharge portion.

[0018] The head immersion method may be a head immersion method using a head immersion device, characterized by the steps of collecting hot water in the bucket main body attached to the shampoo bowl, and applying the hot water discharged from the water discharge section to the head of the person being treated, which is immersed in the collected hot water.

[0019] The head immersion device may have a bottom portion positioned above the bottom surface of a shampoo bowl in which the person to be treated is treated, and a peripheral side portion connected to the periphery of the bottom portion and extending upward. The peripheral side portion has a neck edge portion that faces a neck rest portion on the side edge of the shampoo bowl where the person to be treated's neck is placed, and is characterized by storing hot water for immersing the person's head. In this case, hot water is stored in the head immersion device in the shampoo bowl. Because the neck edge portion of the head immersion device faces the neck rest portion of the shampoo bowl, when the person to be treated places their neck on the neck rest portion, their head is immersed in the hot water. During this time, the person to be treated can relax by having their head immersed in the hot water, and their hair is immersed in the hot water together with their head, thereby removing dirt from their hair. Meanwhile, the treatment continues even if the therapist performs other tasks. This allows the treatment to be performed in a comfortable manner for the person to be treated and without interfering with the therapist's other tasks. In addition, since the bottom is positioned higher than the bottom of the shampoo bowl, a smaller amount of hot water is sufficient compared to when hot water is stored directly in the shampoo bowl.

[0020] The head immersion device may be characterized in that the back of the head of the person being treated can be immersed when the device is full of water. In this case, the back of the head of the person being treated is immersed in hot water, relaxing the person being treated. This allows the treatment to be comfortable for the person being treated and allows the therapist to perform other tasks without being hindered.

[0021] The head immersion device may be characterized in that the neck edge portion faces the neck of the person being treated without contacting it. In this case, hot water can be allowed to flow between the neck rest portion and the neck. The person being treated can relax as the hot water continues to flow around the back of the neck. Furthermore, the continuous flow of hot water allows the treatment to continue, which is comfortable for the person being treated and allows the therapist to perform other tasks without being hindered.

[0022] The head soaking device may be characterized by having legs that contact the bottom surface, so that the head soaking device can be stably placed on the shampoo bowl.

[0023] The head soaking device may be characterized by having legs that can be hooked onto the side edges, allowing it to be stably placed on the shampoo bowl.

[0024] The head soaking device may be characterized by having legs that fit into the drain outlet of the shampoo bowl, so that it can be stably installed on the shampoo bowl.

[0025] The head immersion device may be characterized in that the neck edge has a facing portion that faces the neck of the person being treated, and water flow portions formed on both sides of the facing portion and cut out downward from the facing portion. In this case, when hot water accumulates and the water level rises, the hot water flows from the water flow portions on both sides of the facing portion before the water level reaches the facing portion. In other words, the hot water continues to flow around the back of the neck of the person being treated. This allows the person being treated to relax.

[0026] The head immersion device may be characterized as having a tub body having a bottom and a peripheral side, with a portion facing the neck rest cut out to form a gap, and a neck edge that is detachable through the gap. The neck edge has a facing portion that faces the neck of the person being treated, water flow portions formed on both sides of the facing portion and cut out downward from the facing portion, and guide portions formed on both sides of the water flow portion, extending upward and with ends that jut out in a direction toward each other. In this case, neck edges of various shapes and sizes can be used depending on the type of treatment and the physique of the person being treated. Furthermore, the hot and cold water flows from the guide portions to the ends due to the flowing force, and at the ends, it continues to flow toward the back of the person's neck. This allows the person being treated to relax.

[0027] The head immersion device may be characterized by having grooves formed on both sides of the water flow section and cut toward the bottom to a shallower depth than the water flow section. Even if the person being treated is large and the water flow section is blocked around the back of the neck, preventing the hot water from flowing out of the water flow section, the hot water can still flow through the grooves and reach the back of the neck of a large person being treated.

[0028] The head immersion device may be characterized in that the water flow unit has a notch downwardly cut out from the water flow unit, thereby having a receiving portion on which the neck rest is placed. In this case, even if the neck rest is attached to the shampoo bowl, the neck rest is placed on the receiving portion, so that the neck rest does not interfere with the water flow unit. The hot and cold water flows from the neck rest and continues to flow around the back of the neck of the person being treated. This allows the person to relax.

[0029] The shampoo bowl may be characterized by having the head soaking device described above, in which case the same effects as those of the head soaking device described above can be achieved. [Effects of the Invention]

[0030] The head immersion device of the present invention comprises a tub body attached to the inside of a shampoo bowl where the person to be treated is treated; a pair of hollow rod-shaped members, each extending upward from the tub body and connected at its tip; and a water outlet connected to the lower part of the tip. The rod-shaped members function as a flow path, sending hot water to the tip and from the tip to the water outlet below. The water outlet discharges hot water from inside the tub body to the person's head in a continuous curtain-like stream directly below. The rod-shaped members can be tilted backward to adjust the position at which the hot water hits the head. In this case, hot water collects in the tub body in the shampoo bowl, immersing the head and hair in the water. During this time, the person to be treated can relax and have their hair cleaned. Meanwhile, the treatment continues even if the therapist performs other tasks. This provides a comfortable treatment for the person to be treated and allows the therapist to perform other tasks without interfering with the treatment. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0032] The following is an explanation of a shampoo bowl and head immersion device to which a head immersion device according to an embodiment of the present invention is attached. A scalp massage device, a head immersion device, and the like are attached to the shampoo bowl as treatment devices used for treatment. Figures 1 and 2 show the exterior of shampoo bowl 1. Figure 3 shows a scalp massage device 10 attached to shampoo bowl 1. Figure 4 shows a scalp massage device 10 and a head immersion device 25 attached to shampoo bowl 1. In Figure 1, the depth direction of shampoo bowl 1 is referred to as up and down (Up, Down), the side of the top of the head when the head of person 50 is placed in shampoo bowl 1 is referred to as the back side (Back), the opposite side, the neck side, is referred to as the front side (Front), and the width direction is referred to as the left side (Left Side, Right Side).

[0033] As shown in FIGS. 1 and 2, shampoo bowl 1 is designed for a person 50 to lie face-up on a treatment table (not shown) such as a hairdressing chair and place their head there to receive treatment (see FIG. 32). Treatments include, for example, shampooing, scalp massage, coloring, perming, and eye makeup. Shampoo bowl 1 is, for example, a roughly hemispherical bowl composed of a bottom surface 2 and side surfaces 3. A cylindrical drain outlet 4 is formed in bottom surface 2, and a shower head 5 for discharging hot water and a hot water stop valve 6 are installed inside side surface 3. The front side of side surface 3 is recessed and lower than the other portions of side surface 3, and is equipped with a neck rest 7 as a neck rest on which the person's neck can be placed. Neck rest 7 is composed of a first rest 8 shaped to connect with side surface 3 and a hemispherical second rest 9 positioned behind first rest 8. The second rest 9 consists of a pair of left and right rests 9. The neck of the person to be treated 50 is placed on the first placement portion 8, and the nape, nape of the neck, nape of the neck, etc. (hereinafter referred to as "nape, etc.") of the person to be treated 50 is placed on the second placement portion 9.

[0034] As shown in Figures 3 and 4, a scalp massage device 10 or a head immersion device 25 is attached to the shampoo bowl 1 depending on the type of treatment. The scalp massage device 10 and the head immersion device 25 will now be described with reference to the drawings. Figures 5 to 10 show the appearance of the scalp massage device 10, and Figures 11 to 15 show the appearance of the scalp massage device 10 attached to the shampoo bowl 1. Figures 16 to 25 show the appearance of the head immersion device 25, and Figures 26 to 31 show the appearance and cross section of the head immersion device 25 attached to the shampoo bowl 1.

[0035] As shown in Figures 5 to 10, scalp massage device 10 includes a connecting portion 11 to which shower head 5 is connected, a flow path portion 13 connected to connecting portion 11, a water discharge portion 18 connected to flow path portion 13, and a detachable portion 20 connected to flow path portion 13 and attached to shampoo bowl 1. Connectable portion 11 is cylindrical and extends vertically, with an opening 12 at its top and a lower portion connected to flow path portion 13. Opening 12 includes a detachable fastening means (not shown) for securing shower head 5. The detachable fastening means may be, for example, a string or band for fastening shower head 5, a head immersion device 25 as a weight for pressing down shower head 5 from above, a threaded structure for threading opening 12 and shower head 5, a mechanical fit, or a material selection such as rubber for opening 12 to generate friction between opening 12 and shower head 5.

[0036] The flow path section 13 has a first flow path section 14 connected to the lower part of the connected part 11 and a second flow path section 16 connected to a first tip section 15, which is the tip of the first flow path section 14. Each of the flow path sections 14, 16 is hollow and has a flow path formed therein. The first flow path section 14 is configured as a pair, one on the left and one on the right, with the connected part 11 as the center. The first flow path section 14 extends left and right from the connected part 11 and curves or bends forward, with the first tip section 15 facing upward. The first tip section 15 has a hinge section 23 and a shaft support section 24. The hinge section 23 rotates the second flow path section 16 and moves it back and forth, and the second flow path section 16 is connected via the hinge section 23. The hinge section 23 has a restricting section (not shown) formed therein to limit the range of movement of the second flow path section 16. The shaft support portion 24 is a groove formed at the rear of each first tip portion 15, and is used when a head immersion device 25 is attached (see FIG. 31).

[0037] The second flow path portion 16 extends upward from the left and right first tip portions 15 and curves or bends laterally, connecting at the tip, the second tip portion 17. The water discharge portion 18 is connected to the lower portion of the second tip portion 17. The water discharge port 19 of the water discharge portion 18 faces downward toward the shampoo bowl 1. The detachable portion 20 has a first detachable portion 21 that contacts the bottom surface 2 of the shampoo bowl 1 and a second detachable portion 22 that connects to the drain outlet 4 of the shampoo bowl 1. The first detachable portion 21 protrudes downward from the first tip portion 15, and its length can be adjusted by a screw structure or the like. The second detachable portion 22 is plate-shaped and protrudes downward from the first flow path portion 14 directly below the connected portion 11. The second detachable portion 22 is made of, for example, rubber, silicone, or the like.

[0038] As shown in FIGS. 11 to 15, the scalp massaging device 10 is attached to the shampoo bowl 1. That is, the second detachable part 22 of the scalp massaging device 10 is inserted into the drain outlet 4 of the shampoo bowl 1, and the side of the second detachable part 22 abuts against the inner surface of the drain outlet 4, thereby fitting the second detachable part 22 into the drain outlet 4 (see FIGS. 30 and 31). Because the drain outlet 4 is cylindrical and the second detachable part 22 is plate-shaped, a gap is created between the second detachable part 22 and the drain outlet 4. Therefore, hot and cold water drains through this gap from the drain outlet 4. The first detachable part 21 abuts against the bottom surface 2 of the shampoo bowl 1 and supports the flow path parts 14, 16. Therefore, the flow path parts 14, 16 are supported at three points by the detachable parts 21, 22. During use, the shower head 5 of the shampoo bowl 1 is connected to the connecting part 11 (see FIG. 30).

[0039] As shown in FIG. 15 , the second flow path portion 16 changes its angle relative to the first flow path portion 14 via the hinge portion 23. That is, the second flow path portion 16 tilts backward. The hinge portion 23 has a restricting portion formed therein, limiting its range of motion and preventing it from changing beyond a predetermined angle. The predetermined angle, where zero degrees is defined as the vertical position of the second flow path portion 16, is, for example, 25 to 35 degrees, preferably about 30 degrees, backward, and 5 to 15 degrees, preferably about 10 degrees, forward. If the range of motion is excessively large, the scalp massaging device 10 may come into contact with the side surface 3 of the shampoo bowl 1 when being attached to the shampoo bowl 1, hindering the attachment process.

[0040] The second flow path section 16 is movable in the front-rear direction via the hinge section 23. That is, when the second flow path section 16 rotates, the position of the axis itself changes.

[0041] As shown in Figures 16 to 25, the head immersion device 25 resembles a washbasin or similar tub, narrowing slightly like a funnel. It includes a tub body 26 and a flow straightener 40 serving as a neck edge. Figures 16 to 20 show the tub body 26 in the state before the flow straightener 40 is attached, while Figures 21 to 25 show the head immersion device 25 with the flow straightener 40 attached to the tub body 26. The tub body 26 includes a bottom 27 and a peripheral side portion 28 that is connected to the periphery of the bottom 27 and extends upward. The bottom 27 is formed in a stepped configuration, and a portion of the peripheral side portion 28 is cut out. The stepped configuration of the bottom 27 forms a recessed space 29 on the outer side of the far side of the bottom 27. That is, a bottom side portion 30 extending upward is connected to the rear side of the bottom portion 27, and a stepped bottom portion 31 is connected to the rear side of this bottom side portion 30. A plurality of legs 32 are formed on the underside of the bottom portion 27 to allow the bottom portion 27 to stand on its own. The number, shape, length, position, etc. of the legs 32 are optional. A drain hole 33 is formed in approximately the center of the bottom portion 27. A plug 34 (see Figure 30) is attached and detached to the drain hole 33.

[0042] A portion of the peripheral side portion 28 facing the neck rest 7 is cut out to form a neck gap 48. The airflow rectifying portion 40 is attached and detached to this neck gap 48. A shaft protrusion 36 is formed on the outer surface of the outer edge portion 35, which is the portion of the peripheral side portion 28 other than the neck gap 48. The shaft protrusions 36 are formed as a pair on the left and right, and protrude sideways on the near side of the bottom side portion 30. A pair of left and right grooves 38 are formed on the upper edge of the outer edge portion 35, near the neck gap 48 on the near side. A plurality of small holes 39 are formed in the outer edge portion 35 near the neck gap 48, following the shape of the neck gap 48.

[0043] The flow rectifying portion 40 is a thin plate made of, for example, rubber, silicone, or urethane. It is fastened to the circumferential side portion 28 of the bucket main body 26 by a fastening member 47 and supports the neck edge. The fastening member 47 is shaped to fit the neck edge gap 48 and sandwiches the flow rectifying portion 40 between the circumferential side portion 28 and fastens it via screws or the like. The flow rectifying portion 40 includes a circumferential main body portion 41 fastened to the circumferential side portion 28, a facing portion 42 connected to the upper part of the circumferential main body portion 41, a water flow portion 43 formed by cutting out both left and right sides of the facing portion 42, and guide portions 45 formed on both left and right sides of the water flow portion 43. The facing portion 42 protrudes upward from the center of the upper end of the circumferential main body portion 41. Because both left and right sides of the facing portion 42 are cut out downward toward the circumferential main body portion 41, the water flow portion 43 is formed below the facing portion 42. The water flow portion 43 is cut further downward toward the circumferential main body portion 41, thereby forming a placement portion 44. The second placement portion 9 of the neck rest 7 is placed in this placement portion 44 (see FIG. 26). The guide portion 45 extends upward from the upper end of the circumferential main body portion 41, and its tip, a guide tip portion 46, protrudes in a direction toward each other. In relation to the flow rectification portion 40, the groove portion 38 is positioned outside the placement portion 44 (water flow portion 43) and the guide tip portion 46 along the circumferential direction of the outer edge portion 35, and is cut out from the outer edge portion 35 toward the bottom portion 27 to a shallower depth than the water flow portion 43.

[0044] As shown in Figures 26 to 31, the head immersion device 25 is attached to the shampoo bowl 1 to which the scalp massaging device 10 is attached. The shower head 5 of the shampoo bowl 1 is connected to the connection portion 11 of the scalp massaging device 10, and the stepped bottom portion 31 of the head immersion device 25 is placed on top of the shower head 5. In other words, the head immersion device 25 serves as the means for attaching and detaching the scalp massaging device 10. Note that the detachable attachment means may also be realized by using a string, band, or the like in combination. The axial protrusion 36 of the head immersion device 25 is engaged with the axial support portion 24 of the scalp massaging device 10. Meanwhile, the flow rectifying unit 40 of the head immersion device 25 is attached to the second mounting portion 9 of the neck rest 7. In other words, the second mounting portion 9 is fitted into the mounting portion 44 of the flow rectifying unit 40, and as the mounting portion 44 is closed, the second mounting portion 9 is replaced by the water flow unit 43. Opposing portion 42 of flow rectifier 40 is fitted between second mounting portions 9. Guide portion 45 is fitted along the outer periphery of second mounting portion 9. Flow rectifier 40 faces first mounting portion 8 of neck rest 7. Bottom portion 27 of head immersion device 25 is positioned higher than bottom surface 2 of shampoo bowl 1, and plug 34 is attached to drain hole 33 of bottom portion 27.

[0045] As described above, the scalp massage device 10 and head immersion device 25 are configured.

[0046] Next, the effects of this embodiment will be described together with the operation of this embodiment. Figures 32 to 34 show the state of treatment according to this embodiment.

[0047] As shown in Figures 32 to 34, the person to be treated 50 lies on his / her back and places his / her head in the shampoo bowl 1. At this time, the neck of the person to be treated 50 is placed on the first placement portion 8 of the neck placement device 7. Furthermore, the nape of the person to be treated 50 and the like are placed on the second placement portion 9. The hair of the person to be treated 50 is wetted with hot water from the shower head 5 before the treatment. By wetting the hair in advance, the hot water is prevented from splashing off the hair during the treatment. If the treatment is performed on dry hair, the hot water released from the scalp massage device 10 may bounce off the hair and splash onto the face or clothes of the person to be treated 50.

[0048] The scalp massaging device 10 is attached to the shampoo bowl 1 with the head of the person to be massaged 50 placed in the shampoo bowl 1. The second flow path section 16 of the scalp massaging device 10 is attached in a state in which it is tilted backward. By tilting the second flow path section 16 backward, the scalp massaging device 10 is attached to the shampoo bowl 1 in a position in which the water discharge section 18 does not face the face of the person to be massaged 50. If the scalp massaging device 10 were attached to the shampoo bowl 1 with the second flow path section 16 in a vertical position, hot or cold water remaining in the water discharge section 18 during another massage may splash onto the face or clothes of the person to be massaged 50.

[0049] The shower head 5 is connected to the connecting portion 11 of the scalp massage device 10. If the detachable fastening means is, for example, a band, the shower head 5 is fastened to the connecting portion 11. The head immersion device 25 is placed below the back of the head, attached to the scalp massage device 10, and placed on top of the shower head 5. Attaching the head immersion device 25 to the scalp massage device 10 provides a detachable fastening means in combination with a band or the like. When the head immersion device 25 is placed below the back of the head, if the person 50 has long hair, the head of the person 50 is lifted and all of the hair is contained inside the head immersion device 25.

[0050] When the scalp massage device 10 and the head bathing device 25 are attached to the shampoo bowl 1 in which the head of the person to be treated 50 is placed, the second flow path section 16 of the scalp massage device 10 remains tilted backward, so it is positioned on the top side of the head of the person to be treated 50 and does not face the scalp or hairline. On the other hand, the facing section 42 of the head immersion device 25 faces the nape of the neck of the person to be treated 50. In this case, the facing section 42 does not come into contact with the nape of the neck, etc., leaving a small gap between the nape of the neck, etc. and the facing section 42. Note that which part of the neck, nape, etc. is placed on each of the placement sections 7, 8 varies slightly depending on the physique of the person to be treated 50.

[0051] When the stopcock 6 of the shampoo bowl 1 is operated and hot water is supplied, the hot water is discharged from the shower head 5. Because the shower head 5 is connected to the connecting portion 11 of the scalp massage device 10, the hot water flows from the connecting portion 11 through the first flow path portion 14 and the second flow path portion 16 and is discharged from the water outlet 19 of the water discharge portion 18. The discharged hot water accumulates in the head immersion device 25 without hitting the head of the person to be treated 50. As the water level gradually rises from the bottom 27 of the head immersion device 25, the back of the head is adequately immersed in the hot water. When the water level reaches the second mounting portion 9 of the neck support 7, the hot water detours left and right along the second mounting portion 9 (see water flow 51 in Figure 33 ) and overflows from the left and right sides of the second mounting portion 9 to the outside of the head immersion device 25 (see water flow 52 in Figure 34 ). At this time, the hot water does not flow beyond the opposing portion 42. The nape of the person 50 is placed on the second placement section 9, and the hot water flows along the second placement section 9 and over the nape of the person 50. The nape of the person 50 is not immersed in a still water surface, but is exposed to the continuously flowing hot water, so the person 50 does not feel cold in the nape of the person 50, and can feel the water flow and relax.

[0052] Depending on the force of the flow of hot water, the hot water may flow from the second placement portion 9 around the guide portion 45 and from the guide tip portion 46 toward the nape of the neck, etc. (See water flow 53 in Figure 33). Because the hot water is appropriately directed toward the nape of the neck, etc., the person 50 can be relaxed.

[0053] When the water level reaches the second placement section 9, the bath is full, and since the back of the head of the person to be treated 50 is immersed in the hot water at this time, the person to be treated 50 can relax. In addition, the hair is immersed in the hot water together with the head, and dirt on the hair is washed off.

[0054] After the back of the head has been adequately immersed in the hot water, or after the hot water has overflowed from the left and right sides of the second placement portion 9 and flowed outside the head immersion device 25, the angle of the second flow path portion 16 is adjusted, and the second flow path portion 16 is positioned so that the hot water discharged from the water outlet 19 hits the scalp and hairline. The hot water hits the scalp and hairline and flows down the hair toward the top of the head (see water flow 54 in Figure 34). After the back of the head has been immersed in the hot water, or after the nape of the neck and other areas have been exposed to the hot water, the scalp and hairline are appropriately stimulated by the hot water from the water outlet 19, allowing the patient 50 to properly feel the water flowing at the nape of the neck and other areas. If the hot water from the water outlet 19 is stored in the head immersion device 25 while hitting the scalp and hairline, the scalp and hairline may be stimulated before the nape of the neck is exposed to the hot water, and the person 50 may lose sensation in the nape of the neck.

[0055] During the treatment, the person 50 receives the treatment, as described above, by having their head immersed in hot water and having the water flow over their nape, etc., and the treatment continues even if the therapist performs other tasks. Therefore, the treatment is comfortable for the person 50 and can be performed without interfering with the therapist's other tasks. Even if the therapist performs the treatment, the scalp massage device 10 functions as a shower, so the therapist does not need to hold the shower head 5 and can perform the treatment with both hands.

[0056] In addition, since the bottom 27 of the head soaking device 25 is positioned higher than the bottom surface 2 of the shampoo bowl 1 (see Figure 34), a smaller amount of hot water is sufficient compared to when hot water is stored directly in the shampoo bowl 1.

[0057] In this embodiment, the second placement portion 9 of the neck rest 7 is fitted into the placement portion 44 of the flow rectifier 40 in the head immersion device 25 (see FIG. 26). In other words, even if the neck rest 7 is attached to the shampoo bowl 1, the second placement portion 9 is placed in the placement portion 44, so that the second placement portion 9 does not interfere with the flow rectifier 40.

[0058] When the treatment is finished, the stop valve 6 is operated to stop the hot and cold water. The second flow path section 16 is tilted backward and positioned so that it does not face the head of the person being treated 50. Therefore, even if the hot and cold water remaining in the flow path section 13 drips from the outlet 19, the hot and cold water is prevented from hitting the head.

[0059] In this embodiment, a drain hole 33 is formed in the bottom 27 of the head immersion device 25 and a plug 34 is attached (see Figure 30), so that water can be drained through the drain hole 33 by removing the plug 34.

[0060] The head immersion device 25 is removed from the scalp massage device 10. The shower head 5 is removed from the scalp massage device 10. The moisture from the wet scalp of the person to be massaged is absorbed by a fibrous member such as a towel.

[0061] In this embodiment, the head immersion device 25 has a structure in which the rectifier 40 is attached and detached via a fastening member 47 (see Figures 16 to 25), allowing rectifiers 40 of various shapes to be attached and detached depending on the type of treatment and the physique of the person being treated 50. In addition, the rectifier 40 is a thin plate made of rubber, silicone, urethane, or the like, so it can be easily deformed and replaced.

[0062] In this embodiment, a pair of left and right grooves 38 are formed near the neck edge gap 48 on the upper edge of the outer edge 35 of the head immersion device 25, which is on the near side (see FIG. 22). The grooves 38 are positioned along the circumferential direction of the outer edge 35, outboard of the placement portion 44 (water flow portion 43) and the leading edge 46, and the grooves 38 are cut out from the outer edge 35 toward the bottom 27 to a shallower depth than the water flow portion 43. If the head immersion device 25 is large and the facing portion 42 comes into contact with the nape of the head immersion device 25, the nape of the head immersion device 25 will block the second placement portion 9, preventing the hot water from flowing down the nape. However, the hot water flows through the grooves 38, which are shallower than the water flow portion 43, allowing the hot water to flow down the nape of the neck of the large head immersion device 25.

[0063] In another embodiment of the present invention, the head immersion device 25 does not have a placement portion 44 but has a water flow portion 43 (see Figures 21 and 22). In this case, the water level gradually rises from the bottom 27 of the head immersion device 25, and when it reaches the water flow portion 43, which is lower than the opposing portion 42, the water overflows and flows outside the head immersion device 25. At this time, because the opposing portion 42 is formed higher than the water flow portion 43, the hot water does not flow beyond the opposing portion 42. Because the water flow portion 43 faces the nape of the neck of the person being treated, the hot water flows over the nape of the neck. In this case, the second placement portion 9 may or may not be present.

[0064] Next, the effects of the scalp massage device 10 used in this embodiment will be described.

[0065] The second flow path portion 16 of the scalp massage device 10 extends upward from the first tip portion 15 of the first flow path portion 14 and is curved or bent laterally (see FIG. 7). With this configuration, the second flow path portion 16 does not interfere with the head of the person 50 to be massaged.

[0066] First tip portion 15 of scalp massaging device 10 has hinge portion 23, and second flow path portion 16 changes its angle relative to first flow path portion 14 via hinge portion 23 (see FIG. 15). This configuration changes the position of water discharge portion 18, making it possible to adjust the position at which hot and cold water discharged from water outlet 19 hits the scalp. Also, this makes it easy to attach to shampoo bowl 1.

[0067] Furthermore, the hinge portion 23 is formed with a restricting portion for limiting the range of motion of the second flow path portion 16. This configuration limits the range of motion of the second flow path portion 16, preventing it from changing beyond a predetermined angle. Therefore, for example, hot or cold water will not splash onto the face of the person 50.

[0068] The second flow path portion 16 is movable in the front-rear direction via the hinge portion 23. Therefore, the second flow path portion 16 is appropriately positioned according to the position of the hairline of the person 50 to be treated.

[0069] Next, modified examples of the scalp massaging device 10 will be described with reference to the drawings. Figures 35 to 37 show a modified scalp massaging device 110. Figures 35 and 36 show the external appearance of the scalp massaging device 110, and Figure 37 shows an enlarged cross section of the second detachable part 122 of the scalp massaging device 110 inserted into the drain outlet 4 of the shampoo bowl 1. Note that the following mainly describes configurations that differ from the scalp massaging device 10, and configurations that are the same as those in the scalp massaging device 10 are given the same reference numerals and will not be described again.

[0070] 35 and 36, the second detachable part 122 of the scalp massaging device 110 has a pair of flanges 155 that protrude toward the front and rear sides from the lower part of the front and rear sides. The flanges 155 are approximately semicircular when viewed from above. When viewed from the side, the flanges 155 have a flat upper surface 156 that is the upper surface and an inclined lower surface 157 that is the lower surface. The flat upper surface 156 is a flat semicircular plate, and the inclined lower surface 157 gradually slopes downward from the outer tip toward the second detachable part 122.

[0071] As shown in FIG. 37 , when second detachable part 122 is inserted into drain outlet 4 of shampoo bowl 1, flange portion 155 is positioned deeper than the upper end of the open end of drain outlet 4 and with a gap between it and the inner surface of drain outlet 4. Hot and cold water drained from drain outlet 4 passes through a mesh-like hair collector (not shown) attached inside drain outlet 4. At that time, the hot and cold water flows from flat upper surface portion 156 down drain outlet 4 along inclined lower surface portion 157. That is, the flowing hot and cold water may hit the hair catcher and make an unpleasant sound for person 50. However, when hot and cold water is drained through flange portion 155, the position where the hot and cold water starts to fall is lowered to the lower end of inclined lower surface portion 157, which is lower than bottom surface 2 of shampoo bowl 1, and therefore the distance from the position where the hot and cold water starts to fall to the hair collector is also shortened. Therefore, compared to a case where there is no flange portion 155 and hot water starts to fall from the bottom surface 2, a sound deadening effect is achieved, and the person to be treated 50 can relax without feeling any unpleasant sounds.

[0072] In another embodiment of the present invention, only the head immersion device is attached to the shampoo bowl. In this case, the legs of the head immersion device are formed long so that it can stand on the bottom of the shampoo bowl. Alternatively, instead of the scalp massage device, a stand is installed on the shampoo bowl, and the head immersion device is placed on this stand. Even if there is no scalp massage device, head immersion is preferable because the therapist can perform the treatment with both hands. In another embodiment, the legs are hook-shaped and are configured to hook onto the side edges of the shampoo bowl. In another embodiment, the leg portion is shaped to fit into the drain of the shampoo bowl, for example, in a similar configuration to the second detachable portion of a scalp massaging device. Other embodiments do not have legs. In another embodiment, the facing portion slightly contacts the nape of the neck or the like of the person being treated. Other embodiments do not have a water flow section. In another embodiment, there is no straightening portion, and a neck edge portion having the same shape as the straightening portion is formed on the bucket main body as a portion equivalent to the straightening portion. Other embodiments do not have grooves. In another embodiment, the plug is integral with the flow straightener, i.e., the lower end of the flow straightener extends to the drain hole and the plug is formed at the lower end. In another embodiment, the scalp massaging device has only one second flow passage portion on either the left or right side. In another embodiment, the second detachable part of the scalp massaging device is substantially cylindrical in shape, and a notch, recess, depression, groove, or the like is formed in a part of the second detachable part to create a gap between the second detachable part and the drain outlet. The gap serves as a drainage flow path. In other embodiments, hot water is supplied directly to the head soaking device, such as from a shower head or other water supply, i.e., the water does not pass through the scalp massaging device. In another embodiment, the neck rest is not attached, and a neck rest portion having the same shape as the neck rest is formed on the side of the shampoo bowl as a portion corresponding to the neck rest.

[0073] Next, the water discharger 18 will be described with reference to the drawings. Figures 38 to 44 show the water discharger 18. Figures 38 to 40 show the appearance of the water discharger 18, and Figures 41 to 44 show cross sections of the water discharger 18.

[0074] Here, the water discharger 18 is a component that constitutes the scalp massaging device 10, 110, and the scalp massaging device 10, 110 has the following configuration. It has a connecting part 11 attached to the shampoo bowl 1 and to which the shower head 5 is connected, a flow path part 13 connected to this connecting part 11 and extending upward, and a water discharge part 18 connected to the tip of this flow path part 13, and the water discharge outlet 19 formed on the underside of the water discharge part 18 is U-shaped to resemble the hairline on the forehead of the person being treated 50, and hot and cold water from the shower head 5 passes through the flow path part 13 to the water discharge part 18 and is released from the water discharge outlet 19. The hot and cold water discharged from the water outlet 19 flows continuously along the U-shape of the water outlet 19 from the water outlet 19 to the forehead of the person to be treated 50 without interruption. The flow path within the water discharger 18 is formed with vertically connected levels. The connecting paths between the levels are staggered on the upper and lower levels.

[0075] More specifically, as shown in Figures 38 to 40, water discharge unit 18 is a three-dimensional object that is elliptical or oblong when viewed from above or below, and has a flow path connection unit 200 at its upper part and a water discharge port 19 at its lower part. Flow path connection unit 200 is configured as a pair and is connected to second tip 17 of flow path unit 13 (see Figure 5). Water discharge port 19 is U-shaped following the hairline on the forehead of patient 50, and continues in a linear U shape toward the side. Note that the flow path connection unit may be single. Alternatively, the water discharge port may be a plurality of holes arranged in a U shape.

[0076] As shown in Figure 41, the water discharge section 18 has a flow path therein, which is divided into three levels, one above the other. Specifically, the flow path is realized by a cylindrical main flow path section 201 connected to a flow path connection section 200 from the inside of the water discharge outlet 19, and a U-shaped tiered flow path section 202 connected to the lower end of the main flow path section 201 and extending to the left and right. The downstream side of the tiered flow path section 202 is connected to the water discharge outlet 19. Two partition pieces are formed inside the tiered flow path section 202, and these first and second partition pieces 203 and 204 form three levels, one above the other. The number of levels may be two, four, or more. The number of partition pieces is determined according to the number of levels.

[0077] The layers are composed of an upper layer flow path 205 that communicates with the main flow path section 201, a middle layer flow path 206 that communicates with the downstream side of the upper layer flow path 205, a lower layer flow path 207 that communicates with the downstream side of the middle layer flow path 206, a water outlet connection path 208 that communicates from the downstream side of the lower layer flow path 207 to the water outlet 19, an upper-middle connection path 209 formed by separating the upper layer flow path 205 and the middle layer flow path 206 with a first partition piece 203, and a middle-lower connection path 210 formed by separating the middle layer flow path 206 and the lower layer flow path 207 with a second partition piece 204. The connection paths 209, 210 between the layers are staggered on the upper layer side and the lower layer side. That is, because the first partition piece 203 is formed to protrude rearward (to the right in FIG. 41), the upper-middle connecting passage 209 communicates with the rear of the upper layer flow path 205 and the rear of the middle layer flow path 206 (to the right in FIG. 41), while the second partition piece 204 is formed to protrude forward (to the left in FIG. 41), so the middle-lower connecting passage 210 communicates with the front of the middle layer flow path 206 and the front of the lower layer flow path 207 (to the left in FIG. 41). Therefore, the upper-middle connecting passage 209 and the middle-lower connecting passage 210 are arranged offset from each other in the front and rear directions. The flow paths snake back and forth within the tiered flow path section 202.

[0078] The front-to-rear width of each of the connecting passages 209, 210 between the levels narrows going down the level. More specifically, the front-to-rear width of the middle-lower connecting passage 210 shown in Fig. 43 is narrower than the front-to-rear width of the upper-middle connecting passage 209 shown in Fig. 42, and the front-to-rear width of the outlet connecting passage 208 shown in Fig. 44 and the front-to-rear width of the outlet 19 shown in Fig. 40 are narrower than the front-to-rear width of the middle-lower connecting passage 210. As shown in Fig. 43, in the middle-lower connecting passage 210, the front-to-rear width of the left and right side regions 212 is wider than the front-to-rear width of the central region 211.

[0079] Water discharger 18 is configured as described above. Next, the effects of water discharger 18 will be described together with its operation.

[0080] Hot water supplied to the scalp massage device 10, 110 passes through the main flow path section 201 and tiered flow path section 202 in the water discharge section 18 before being discharged from the water discharge port 19. In the tiered flow path section 202, the hot water snakes through the upper layer flow path 205, the upper-middle connecting path 209, the middle layer flow path 206, the middle-lower connecting path 210, the lower layer flow path 207, and the water discharge port connecting path 208, and is discharged in a U-shape from the water discharge port 19. The hot water discharged from the water discharge port 19 flows continuously, like a water wall, from the water discharge port 19 to the forehead of the person being treated. In other words, the hot water that flows continuously and uninterrupted along the U-shape of the water discharge port 19 resembles a curtain or a glass surface. In particular, in the middle-lower connecting passage 210, the front-to-back width of the left and right side sections 212 is wider than the front-to-back width of the central section 211, so the flow rate of hot and cold water is greater in the left and right side sections 212 than in the central section 211, forming a continuous, unbroken U-shape.

[0081] The hot water hits the scalp and hairline of the person being treated 50 and flows down the hair toward the top of the head (see water flow 54 in Figure 34). The hot water from the water outlet 19 moderately stimulates the scalp and hairline of the person being treated 50, allowing them to relax. Meanwhile, the treatment continues even if the therapist performs other tasks. Therefore, the treatment is comfortable for the person being treated 50 and can be performed without interfering with the therapist's other tasks. In particular, because the hot water is in a continuous U-shape without interruption, the person being treated 50 does not feel uncomfortable. Note that if the hot water is interrupted or released individually from multiple holes like a shower, the person being treated 50 will intuitively know that the hot water is interrupted and hitting the scalp and hairline, which may cause discomfort and distracting thoughts that may interfere with relaxation.

[0082] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made to the present invention without departing from the scope of the claims.
