  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view schematically illustrating the appearance of a shower bath device according to an embodiment of the present invention.
2 is a cross-sectional view taken along line AA in FIG.
3 is a cross-sectional view taken along the line BB in FIG.
4 is a cross-sectional view taken along the line CC in FIG.

  The shower bath device according to the present embodiment mainly includes a back surface portion 2 provided on the wall surface 100 of the bathroom and a base portion 3 provided on the floor surface 110 of the bathroom. In this specific example, the base 3 is integrally provided at the lower part of the back surface 2. However, this invention is not limited to this, You may provide the base part 3 and the back surface part 2 separately.

  The base part 3 is on a business trip to the front side of the back part 2 (in the direction of arrow y in FIG. 1). On the upper surface of the pedestal 3, a concave seat 4 is formed that is recessed toward the floor surface 110 than other portions of the upper surface. That is, between the both ends of the upper surface of the base part 3 and the seat part 4 as viewed in the first direction x (the width direction of the base part 3) substantially parallel to the bathroom wall surface 100 and the bathroom floor surface 110, there is no wall. A step is formed through the portion 6.

  The back portion 2 is formed with a concave backrest portion 5 that is recessed toward the bathroom wall surface 100 with respect to other portions of the back portion 2. That is, a step is formed between the both end portions of the back surface portion 2 as viewed in the first direction x and the backrest portion 5 via the wall portion 7.

  The backrest portion 5 and the seat portion 4 are formed as a continuous recess. The wall portion 7 provided at both ends of the backrest portion 5 viewed in the first direction x (width direction) and the wall portion 6 provided at both ends of the seat portion 4 viewed in the first direction x (width direction) are also provided. It is a connection.

  As illustrated in FIGS. 3A and 3B, the seat 4 is formed in a concave shape when viewed in the first direction x (width direction). Further, as shown in FIG. 3B, a pair of recesses 4A may be provided. These recesses 4 </ b> A are formed extending in the second direction y and correspond to the thighs of the seated person sitting on the seat 4. By providing such a recess 4A, the thigh of the seated person can be supported more stably, and the hot water accumulated in the seat 4 can flow toward the leg of the seated person.

  Further, as shown in FIG. 2, the seat portion 4 is inclined downward in the depth direction (toward the backrest portion 5). That is, the indentation depth of the seat portion 4 is gradually increased in the depth direction (toward the backrest portion 5).

  To support the head of a seated person sitting on the seat part 4 or the part from the neck to the head at the upper part of the back part 2 and in the substantially central part seen in the first direction x (width direction). The head support portion 25 is provided. The head support part 25 is in a business trip in the second direction (the protruding direction of the base part 3) y with respect to the back part 2.

  A pair of first water discharge portions 21 is provided on the back surface portion 2 above the backrest portion 5. One first water discharge portion 21 is provided on each of the left and right sides of the head support portion 25 so as to sandwich the head support portion 25 in the first direction x. The first water discharger 21 is positioned above the shoulder of the seated person when the user is seated on the seat 4. Further, the height between the seat 4 and the first water discharger 21 is larger than the height of the seat 4 from the bathroom floor 110. When the user is seated on the seat 4, the two first water dischargers 21 are positioned so that the face or head of the seated person can be positioned between the pair of first water dischargers 21. They are separated from each other in the first direction x. That is, the pair of first water dischargers 21 is provided at a position sandwiching the face or head of the seated person while the user is seated on the seat. However, the first water discharger 21 may be provided at a position higher than the head of the user seated on the seat 4. The water discharge direction of the first water discharge unit 21 is set to be substantially horizontal or slightly below the horizontal direction.

  Here, the “substantially horizontal direction” is preferably within ± 45 ° with respect to the horizontal plane, and more preferably within ± 30 °. Further, it is more desirable that the angle is within ± 20 ° with respect to the horizontal plane.

  That is, as will be described in detail later, a shower flow that falls in the vicinity of the lower limb of the seated person is discharged from the first water discharging section 21 provided above the shoulder of the seated person sitting on the seat section 4. In this case, when the mounting position of the first water discharger 21 is low, the shower flow can be discharged almost horizontally over the shoulder of the seated person and dropped near the lower leg of the seated person. On the other hand, when the mounting position of the first water discharger 21 is high, if the water is discharged in the horizontal direction, the shower flow falls farther than the lower limbs of the seated person, so it is necessary to discharge water downward from the horizontal direction. . That is, when the attachment position of the first water discharger 21 is low, water is discharged almost in the horizontal direction, and the water discharge direction needs to be lower than the horizontal direction as the attachment position becomes higher.

  For example, when the mounting position of the first water discharger 21 is low and water is discharged in a substantially horizontal direction, the flight distance until the shower flow falls near the lower limbs of the seated person is shortened. As a result, the temperature of the shower flow Decline is unlikely to occur. Moreover, a shower bath apparatus can be reduced in size by making the attachment position of the 1st water discharging part 21 low. In addition, the speed when the shower flow falls near the lower limbs of the seated person becomes slow (because there is little influence of the acceleration when water is discharged downward), so the shower person is stimulated and splashed. The seated person can take a full body shower comfortably for a long time.

  In this specific example, a pair of left and right first water discharge portions 21 are provided, but the present invention is not limited to this, and one first water discharge portion 21 may be provided. In this case, the first water discharger 21 is provided across the left and right sides of the head support 25.

  A pair of second water discharge portions 22 is provided on the back surface portion 2 above the backrest portion 5 and below each of the pair of first water discharge portions 21. The water discharge direction of the second water discharger 22 is set to be lower than the water discharge direction of the first water discharger 21 and is set to discharge water toward the seated person's shoulder. In this specific example, a pair of left and right second water discharge portions 22 are provided, but the present invention is not limited to this, and one second water discharge portion 22 may be provided. In this case, the second water discharger 22 is provided near the center.

  The back surface portion 2 is substantially the same height as the second water discharge portion 22 or slightly above the second water discharge portion 22, and is the first than the first and second water discharge portions 21, 22 and the backrest portion 5. A pair of third water dischargers 23 are provided on the outer side in the direction x (the width direction of the backrest 2). The water discharge direction of the third water discharger 23 is set to the inside in the first direction x with respect to the water discharge direction of the first water discharger 21 and is set to discharge water toward the shoulder portion of the seated person. ing.

  From each water discharging part 21-23, the shower flow of about 40-45 degreeC is discharged, for example. In addition, you may provide two or more pairs of each water discharging parts 21-23. Moreover, in this specific example, each water discharging part 21-23 is the structure which each independently protruded, However, this invention is not limited to this, For example, these water discharging parts 21-23 are united. It may be built in the body integrally.

  Moreover, in the base part 3, the recessed part 28 dented in the bathroom wall surface 100 side is formed in the front part 27 located in the front side seen in the protruding direction (2nd direction y). A step is formed between both end portions of the front surface portion 27 viewed in the first direction x and the concave portion 28 via the wall portion 8. The concave portion 28 is connected to the seat portion 4, and the wall portion 8 is connected to the wall portions 6 formed at both ends of the seat portion 4.

  A foot tub 29 is provided on the bathroom floor 110 in front of the recess 28. Hot water discharged from the first to third water discharge portions 21 to 23 is accumulated in the foot tub 29 through the body surface of the seated person or through the backrest portion 5 and the seat portion 4.

  Next, FIG. 5 is a water supply piping system diagram for the water dischargers 21 to 23.

  The 1st-3rd water discharging parts 21-23 are connected to piping 51a-51c, respectively. A flow rate control device 62 is provided in the middle of the pipe 51 a for supplying running water to the first water discharger 21. The flow rate control device 62 changes the flow rate when the shower flow is discharging from the first water discharger 21.

  FIG. 6 is a perspective view schematically showing the configuration of the flow control device according to the first specific example of the present embodiment.

  In this specific example, a cylindrical casing 64 is liquid-tightly provided in the middle of the pipe 51a. A cylindrical rotating body 65 is provided inside the casing 64. A drive shaft 61 a of the motor 61 is connected to the axial center position of the rotating body 65.

  On the peripheral surface of the rotating body 65, a strip-shaped opening groove 66a is formed in a substantially central portion in the vertical direction (a direction substantially orthogonal to the pipe extending direction) so as to face the pipe 51a. Yes. Furthermore, on the peripheral surface of the rotator 65, through openings 66b facing each other at intervals of 180 ° are formed so as to intersect the opening grooves 66a. The opening area of the through opening 66b is larger than the opening area of the opening groove 66a. The opening groove 66a is formed so that the opening area of the opening groove 66a gradually increases from the intersection with the through opening 66b.

  By rotating the motor 61, the columnar rotating body 65 rotates around the axial direction. With this rotation, the state in which the pipe 51a faces the opening 66b having a larger opening area and the state facing the opening 66a having a smaller opening area than the opening 66b are periodically repeated. Thereby, the flow volume of the flowing water which passes the rotary body 65 changes, and the 1st water discharging part 21 discharges a shower flow, changing a flow volume.

  FIG. 7 is a perspective view schematically showing the configuration of the flow control device according to the second specific example of the present embodiment.

  In this specific example, a cylindrical casing 68 is liquid-tightly provided in the middle of the pipe 51a. A spherical rotating body 69 is provided inside the casing 68. On the extension of the center of the rotating body 69, a drive shaft 61a of the motor 61 is connected.

  The rotating body 69 is formed with a through hole 69a eccentric from the center. When the rotating body 69 is rotated by the rotation driving of the motor 61, the area of the through hole 69a facing the pipe 51a is changed, thereby changing the flow rate of the flowing water passing through the rotating body 69, and the first water discharger 21 is The shower flow is discharged while changing the flow rate.

8 and 9 are diagrams schematically showing the configuration of the flow control device according to the third specific example of the present embodiment.
FIG. 8 shows a cross section obtained by cutting the pipe 51a in a direction perpendicular to the extending direction, and FIG. 9 shows a cross section cut along the extending direction of the pipe 51a.

  In this specific example, a part of the eccentric cam 70 is rotatably inserted into the pipe 51a. The eccentric cam 70 is connected to the drive shaft 61a of the motor 61 outside the pipe 51a.

  When the eccentric cam 70 is rotated by the rotational drive of the motor 61, the size of the space under the cam 70 in the pipe 51a changes as shown in FIGS. 9A and 9B. The flow rate of the flowing water changes, and the first water discharger 21 discharges the shower flow while changing the flow rate.

Next, the operation of the shower bath device according to the present embodiment will be described.
FIG. 10 is a perspective view schematically illustrating a state of water discharge in the shower flow from each of the water discharge units 21 to 23 with respect to the seated person 200.

  As shown in FIGS. 2 and 10, from the first water discharge portion 21, a shower flow that drops in the vicinity of the front edge of the jet seat portion 4 in the substantially horizontal direction is discharged. In other words, the shower flow is discharged over the shoulder of the seated person 200 to the front of the seated person 200 by a trajectory that draws an arc by its own weight, and the shower flow falls in the vicinity of the lower limb of the seated person 200, particularly around the thigh. At this time, the shower flow may fall not only on the lower limbs of the seated person 200 but also on the abdomen.

  And this shower flow flows on the surface of the abdomen and the lower limbs from the knee of the seated person 200 toward the foot. By setting in such a water discharge direction, even if the first water discharge portion 21 is provided in the vicinity of the head far from the lower limb of the seat occupant 200, the seat occupant 200 By discharging water over the shoulders of the 200, the discharged water flow can be surely reached to the vicinity of the lower limbs without being obstructed by the seated person 200, so that the lower limbs can be warmed from the knees. In addition, by discharging water from a high position in this manner, a massage effect due to a shower flow can be applied to the lower limbs as in the case of “Utase hot water”.

  Further, depending on the angle of the backrest part 5 and the posture of the seated person 200, the shower flow discharged from the first water discharging part 21 can be dropped to the lower abdomen of the seated person 200.

  The shower flow from the first water discharger 21 is not limited to the case where the shower flow passes just above the shoulder of the seated person 200 but also the case where the shower flows near the shoulder (shoulder tip) of the seated person 200. It is. However, if the shower flow passes right above the shoulder of the seated person 200, the shower flow reaches the vicinity of the lower limb at the shortest distance from the first water discharge portion 21 provided on the back side of the seated person 200. be able to. That is, the temperature drop during the flight until the shower flow discharged from the first water discharger 21 reaches the vicinity of the lower limb can be suppressed, and the vicinity of the lower limb can be warmed with the shower flow at a desired temperature.

  From the second water discharger 22, a shower flow is discharged toward the shoulder near the base of the neck of the seated person 200. Part of the shower flow that hits the shoulder flows on the front surface of the body centering on the side from the chest to the torso of the seated person 200, and the other part of the shower flow wraps around the back. In this way, both the front side and back of the seated person 200 can be warmed. Moreover, the massage effect by a shower style can also be made to act on a shoulder part. When only one second water discharge portion 22 is provided as described above, for example, a shower flow is discharged from the back of the neck of the seated person 200 toward both shoulders near the base of the neck. An effect is obtained.

  The shower flow is discharged from the second water discharge portion 22 toward the shoulder near the base of the neck of the seated person 200, and the shower flow is caused to flow to the front and back of the upper body of the seated person 200. Even if it is only a pair of 2nd water discharging parts 22 provided in, the whole upper half of the seated person 22 can be warmed efficiently. That is, a high thermal effect can be obtained while reducing the cost by minimizing the water discharge portion.

  The hot water that wraps around the back side of the seated person 200 continuously flows toward the seat part 4 along the back or backrest part 5 of the seated person 200. That is, since the hot water discharged from the second water discharge portion 22 flows into the backrest portion 5 one after another, there is no temperature boundary layer between the back and the backrest portion 5 of the seated person 200, and the heat of the hot water is generated by the seated person 200. It becomes easy to be transmitted to the back. Since the back of the human body has a high density of thermal receptors (the part where the human body feels heat), the thermal effect can be enhanced even with a small flow rate, and it also saves water and saves energy by saving the amount of hot water used.

  Moreover, since the backrest part 5 is partitioned off by the wall part 7 formed in the both ends of the 1st direction x (width direction), and is formed in the concave shape connected to the seat part 4, it flowed into the backrest part 5. Hot water can be reliably guided to the seat 4 without waste by suppressing scattering and outflow of hot water. In other words, even if the flow rate is small, the thermal effect is not impaired, and water saving and energy saving are achieved by saving the amount of hot water used.

  From the 3rd water discharging part 23, a shower flow is discharged toward the shoulder part (shoulder top part) of the seated person 200. The shower flow that hits the shoulder portion flows to a portion around the center of the arm that cannot be covered by the shower flow from the first and second water discharge portions 21 and 22, and warms the portion. By discharging the shower flow from the third water discharge portion 23 toward the shoulder portion, the arm portions that cannot be covered by the first and second water discharge portions 21 and 22 can be covered with only one pair of water discharge portions 23. Coverable and low cost.

  Hot water discharged from the first to third water discharge portions 21 to 23 is accumulated in the concave seat portion 4 along the body surface or the backrest portion 5 of the seated person 200. By storing hot water in the seat portion 4, at least the back side of the buttocks and thighs of the seated person 200 is surely in contact with the hot water. Thereby, the waist | hip | lumbar part vicinity where the water discharge from each water discharge part 21-23 does not hit directly can be warmed efficiently. In addition, warming the lower back can activate intestinal movement.

  The seat portion 4 is partitioned by walls 6 formed at both ends in the first direction x (width direction), and is formed as a recess connected to the backrest portion 5, so that lateral leakage of hot water is suppressed, Hot water from the water dischargers 21 to 23 can be used efficiently without waste. That is, it is possible to save water and save energy by saving the amount of hot water used.

  Since the hot water flows into the seat 4 along the body surface or the backrest 5 of the seated person 200 one after another, a temperature boundary layer is not formed between the seated person 200 and the seated part 4, and the heat of the hot water is generated by the seated person. It becomes easy to be transmitted to 200 buttocks and thighs, and the thermal effect can be enhanced.

  Furthermore, the hot water accumulated in the seat part 4 flows out forward (direction y in FIG. 1) and flows from the leg part of the seated person 200 to the foot. As a result, the feet can be warmed up without wasting hot water. In particular, if the recess 4A as illustrated in FIG. 3B is provided, the hot water accumulated in the seat 4 is easy to flow toward the leg of the seated person 200, which is efficient.

  In addition, by immersing the shower flow from the first to third water dischargers 21 to 23 throughout the body while immersing in the hot water accumulated in the seat 4, the sensation of bathing (the feeling of bathing) ) And a high thermal effect can be obtained while being a shower bath. And compared with the case where it is immersed in a bathtub, water pressure is not applied to a body and there are few burdens to a body. Since there is no need to move in and out of the bathtub and it can be used while sitting, a high thermal effect can be easily obtained even for an elderly person or a user who has a physical movement disorder. Also, instead of taking a shower for each part of the body, the whole body can be showered at the same time, so the body can be warmed by taking a shower while saving water in a short time.

  Further, since the water discharged from each of the water discharge units 21 to 23 is not a spray but a shower flow made of a continuous water flow, the surrounding space becomes a high-temperature and high-humidity atmosphere as in the case of spraying mist (spray). Therefore, you can prevent the upside-down. Furthermore, since the temperature drop of the discharged water due to the heat of vaporization is small, it is not necessary to set the shower temperature higher than necessary, which is economical.

  In addition, the shower flow discharged from the 1st-3rd water discharging parts 21-23 in the shower-bath apparatus of this embodiment is discharged from the several shower hole provided in each water discharging part. The hole diameter is desirably within a range of 0.2 mm to 4 mm, for example, and within this range, the hole can be efficiently heated over a wide range with a small flow rate.

  In addition, the seated person 200 is immersed in hot water accumulated in the foot tub 29 so that the seated person 200 is farthest from the first to third water discharging parts 21 to 23, the blood flow is difficult to flow, and the skin temperature is low. The thermal effect of the part can be enhanced. In addition, there is an arteriovenous anastomosis (AVA) in the foot, and when the foot is immersed in the hot water of the foot tub 29, the AVA opens to increase blood flow, thereby further enhancing the thermal effect of the whole body. .

  In addition, by providing the front surface portion 27 of the base portion 3 with the concave portion 28 connected to the seat portion 4, even if hot water accumulated in the seat portion 4 overflows, it flows into the foot bath 29 without flowing sideways and flowing through the concave portion 28. Since it accumulates, the hot water from the water discharge parts 21-23 can be utilized without waste.

  Moreover, compared with patent document 1 with which the arm which provided the several water discharging part protrudes ahead of a seated person, in this embodiment, by providing each water discharging part 21-23 in the bathroom wall surface behind the seated person 200 integrally. In the limited bathroom space, the installation space can be saved, and the compact and clean structure eliminates the annoyance in the bathroom and does not impair the design. Further, since there is no arm protruding forward, for example, the operation of transferring the user from the wheelchair to the seat 4 of the shower bath device can be performed safely and easily, and it is easy to use.

  In addition, by appropriately setting the water discharge direction of the shower flow from each of the water discharge units 21 to 23 as described above, a minimum amount of water discharge units are not provided in front of the seated person 200, so that the minimum amount is provided behind the seated person. A shower bath that efficiently warms the entire body of the seated person 200 can be realized even with a small amount of hot water. Costs can be reduced by minimizing the water discharge part. Moreover, it becomes water saving and energy saving by suppressing the amount of hot water required.

  Furthermore, in the present embodiment, the first flow spouting unit 21 discharges the shower flow while changing the flow rate by the flow rate control device as described above, and as shown in FIG. A shower flow is discharged from the water discharger 21 while changing the flight distance. Thereby, for example, foot traces, calves, thighs, hips, chest can be massaged in order from the first water discharger 21 so as to follow the flow of lymph in the human body, and such operation By repeating a plurality of times, a smooth flow of lymph can be promoted.

  It should be noted that by changing the flight distance of the shower flow in this manner, the water discharge can be moved from the toes to the calves, thighs, waist and chest when the seated person is sitting on the seat 4. This is because the water discharge direction is the y direction (see FIG. 1), and the lower limbs extend in the y direction (see FIG. 1). According to the present invention, the shower flow is adjusted according to the user's physique, physique, and sitting preference by arranging the posture of the seated person and the water discharge direction of the shower flow in a unique relationship as described above. be able to.

  In addition, by changing the flight distance of the shower flow from the first water discharger 21, the shower flow is moved in the order of the toes, calves, thighs, hips, and chest in order, so that the entire body of the seated person can be uniformly distributed. It can be showered, and can also save water and save energy.

  FIG. 12 is a diagram illustrating a specific example of the massage mode (time change in water discharge flow rate) using the shower flow from the first water discharge unit 21.

  In FIG. 12, the horizontal axis represents time, and the vertical axis represents the flow rate Q (liter / minute). The maximum flow rate Qmax is, for example, 12 (liters / minute), and the pressure Pmax at this time is, for example, 0.13 (MPa). The minimum flow rate Qmax is, for example, 6 (liters / minute), and the pressure Pmax at this time is, for example, 0.05 (MPa).

  In this specific example, the flow rate is periodically increased and decreased. That is, first, during the first predetermined time T1, the flow rate is increased relatively rapidly, and the shower flow is moved relatively rapidly toward the seated person's feet as shown in FIG. Let

  When the flow rate reaches Qmax after the first predetermined time T1, the flow rate is gradually decreased over a second predetermined time T2 longer than the first predetermined time T1. At this time, as shown in FIG. 15 through FIG. 13 to FIG. 14, the flight distance of the shower flow from the first water spouting portion 21 is gradually shortened so that the lymph fluid flow of the human body is traced. The foot tip, the calf, the thigh, the waist, and the chest are massaged so as to be slowly put away by the shower flow from the first water discharger 21. As described above, by changing the flight distance of the shower flow in this way, the water discharge can be moved from the toes to the calves, thighs, waist and chest when the seated person is sitting on the seat 4 This is because the water discharge direction of the shower flow is the y direction (see FIG. 1), and the lower limbs extend in the y direction (see FIG. 1). That is, according to the present invention, by arranging the seated person's posture and the water discharge direction of the shower flow in a unique relationship in this way, the shower flow can be made according to the user's physique, body shape, and sitting preference. Can be adjusted.

  Further, such increase and decrease of the flow rate is periodically repeated, and lymphatic massage by the shower flow from the first water discharger 21 is repeatedly performed. Thereby, the smooth flow of lymph can be promoted.

  As described above, the time T2 of the flow rate change (decrease in the flow rate) in the movement direction following the flow of lymph fluid is set to be longer than the time T1 of the flow rate change (increase in the flow rate) following the flow in the reverse direction of the lymph fluid flow. By making it longer, the effect of lymphatic massage by the shower style is enhanced.

  FIG. 16 is a diagram illustrating another specific example of the massage mode (time change of the water discharge flow rate) using the shower flow from the first water discharge unit 21.

  In FIG. 16, the horizontal axis represents time, and the vertical axis represents the flow rate Q (liters / minute). The maximum flow rate Qmax is, for example, 12 (liters / minute), and the pressure Pmax at this time is, for example, 0.13 (MPa). The minimum flow rate Qmax is, for example, 6 (liters / minute), and the pressure Pmax at this time is, for example, 0.05 (MPa).

  Also in this specific example, during the first predetermined time T1, the flow rate is increased relatively rapidly. When the flow rate reaches Qmax after the first predetermined time T1, the first flow is longer than the first predetermined time T1. By gradually decreasing the flow rate over a predetermined time T2 of 2, the flight distance of the shower flow from the first water spouting portion 21 is gradually shortened so that the lymph fluid flow of the human body can be traced. The calf, the thigh, the waist, and the chest are massaged by the shower flow from the first water discharger 21 in this order. As described above, by changing the flight distance of the shower flow in this way, the water discharge can be moved from the toes to the calves, thighs, waist and chest when the seated person is sitting on the seat 4 This is because the water discharge direction of the shower flow is the y direction (see FIG. 1), and the lower limb extends in the y direction (see FIG. 1). According to the present invention, the shower flow is adjusted according to the user's physique, physique, and sitting preference by arranging the posture of the seated person and the water discharge direction of the shower flow in a unique relationship as described above. be able to.

  Further, such increase and decrease of the flow rate is periodically repeated, and lymphatic massage by the shower flow from the first water discharger 21 is repeatedly performed. Thereby, the smooth flow of lymph can be promoted.

  Furthermore, in this specific example, the flow rate is decreased as a whole while the flow rate is repeatedly increased and decreased in small increments at the second predetermined time T2 when the flow rate is decreased. That is, during the massage time T2 along the flow of the lymph fluid, the flow rate is finely increased and decreased to finely vibrate the falling point of the shower flow, and the lymph flow can be further promoted while removing the clogging of the lymph.

  FIG. 17 is a diagram illustrating another specific example of the water supply piping system to each of the water discharge units 21 to 23.

  In this specific example, a flow rate control device 62 is provided in the middle of the water supply pipe 51 commonly connected to each of the water dischargers 21 to 23.

  Therefore, in this specific example, not only the first water discharger 21 but also the second and third water dischargers 22 and 23 can discharge the shower flow while changing their flow rates. As a result, a massage effect as described above can be obtained by the shower flow from the second and third water dischargers 22 and 23.

  FIG. 18 is a diagram illustrating still another specific example of the water supply piping system to the water discharge units 21 to 23.

  In this specific example, the first to third water dischargers 21 to 23 are connected to the pipes 51a to 51c, respectively. And the flow control apparatus 62 is provided in the middle of each piping 51a-51c.

  Therefore, the flow rate of the flowing water supplied to each water discharger 21 to 23 can be individually controlled independently, and the range of the massage massage by the shower flow from each water discharger 21 to 23 and the degree of freedom of controllability of the speed As a result, the user's physique, physique, sitting style, preferences, etc. can be handled more flexibly.
