Hereinafter, embodiments of the present invention will be illustrated with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
In addition, as described below, the drive unit flow path includes a first drive unit flow path that reaches the hydraulic drive device, and a second drive unit flow path that heads from the hydraulic drive device to the water discharger. .
FIG. 1 is a schematic view for illustrating the configuration of the shower device according to the first embodiment of the invention.
FIG. 2 is a schematic perspective view for illustrating the appearance of the shower device according to the present embodiment. 3 is a schematic front view of the shower apparatus illustrated in FIG. 2, and FIG. 4 is a cross-sectional view taken along line AA in FIG.

As shown in FIGS. 1 to 4, the shower device 1 includes a hydraulic drive device 2, a water discharge unit 3, a switching unit 4 having a built-in valve body 13 (see FIG. 9), a constant flow valve 5, And a housing 6. In addition, a water stop valve 7 and a temperature control valve 8 are provided in the piping that forms the water supply flow path 16 to the shower device 1. The water supply channel 16 is branched into a drive unit channel (first drive unit channel) 9 a that reaches the hydraulic drive device 2 and a main channel 9 b that reaches the water discharge unit 3. Furthermore, a flow path (second drive section flow path) 282 that communicates with the hydraulic drive device 2 and the water discharge section 3 is provided. Fluid such as hot water supplied to the water inlet of the temperature control valve 8 can be discharged from the nozzle hole 3c of the water discharger 3 as water discharge W2 (shower water discharge).
In the present embodiment, the switching unit 4 serves as a branching part that branches the flow path into the main channel 9b and the drive part channel 9a. However, the switching unit 4 is provided downstream of the branching part instead of the branching part. You can also.

  As shown in FIG. 2, the water discharge part 3 has a flat part in the radial direction of the cylindrical main body 3a, and the flat part is provided with a nozzle plate 3b provided with a plurality of nozzle holes 3c. Moreover, as shown in FIG. 4, the space 3d provided inside the main body 3a and the nozzle hole 3c communicate with each other. One axial end face of the main body 3a is provided so that a shaft 3e having a flow passage therein protrudes, and the other axial end face is provided with a hole 3f having a circular cross section. And the flow path provided in the axis | shaft 3e and the hole 3f are connected with the space 3d provided in the inside of the main body 3a.

  The main body 3a is repeatedly moved in the direction of the arrow R (see FIG. 2) by the shaft 3e and the water discharge cylinder 280 (see FIG. 5 for details) mounted so as to be liquid-tight in the hole 3f (this embodiment) According to the form, it is held freely. In addition, the fluid W1 can flow into the space 3d through the flow path provided in the shaft 3e and the flow path 282 provided in the water discharge cylinder 280. The fluid W1 flowing into the space 3d can be discharged from the nozzle hole 3c as discharged water W2. That is, in the example illustrated in the present embodiment, the flow path 282 functions as a second drive section flow path for supplying the fluid discharged from the hydraulic drive device 2 to the water discharge section 3.

  When a predetermined amount of fluid is supplied, the hydraulic drive device 2 repeatedly moves the main body 3a of the water discharger 3 in the direction of the arrow R. That is, the water discharger 3 discharges water while performing repetitive motion. In the present embodiment, as will be described in detail later, by switching the switching unit 4, it is possible to stop the driving of the hydraulic drive device 2. Furthermore, in the state (first state) in which the hydraulic drive device 2 is driven to cause the main body 3a to repetitively move and the water is discharged from the main body 3a while the hydraulic drive device 2 is stopped (second state). The amount of water discharged from the main body 3a can be made the same. These points will be described in detail later. In the first state and the second state, hot water is discharged from the same nozzle hole.

Next, the hydraulic drive device 2 will be described with reference to a specific example.
5 to 7 are schematic views for illustrating a hydraulic drive device. FIG. 8 is a schematic diagram for explaining the operation of the hydraulic drive unit. 7 is a cross-sectional view taken along line BB in FIG.
As shown in FIGS. 5 to 7, the hydraulic drive device 2 has a form in which a water discharge cylinder 280 protrudes from a housing formed by a housing main body 202 and housing lids 203 and 204. The water discharge cylinder 280 has a hollow structure having a flow path 282 inside, and is open at the tip. When the fluid W1 is introduced into the water inlets 212 and 214 provided in the housing main body 202, the water discharge cylinder 280 moves repeatedly in the direction of the arrow M (see FIG. 8). In addition, the water discharge cylinder 280 is attached to the hole 3f of the water discharge part 3 so as to be liquid-tight, and the water discharge cylinder 3 280 and the water discharge part 3 are interlocked so that the water discharge part 3 repeatedly moves. ing. And the fluid W1 which flowed out from the flow path 282 is supplied to the water discharging part 3, and is discharged from the nozzle hole 3c as the water discharging W2.
The internal structure will be described. As shown in FIGS. 5 to 7, a core comprising a core body 220 and a core lid 222 in a fan-shaped housing space formed by the housing body 202 and the housing lids 203 and 204. Is accommodated in a swingable manner with the water discharge cylinder 280 as a central axis.
A core inner flow path 224 is formed in the core by combining the core main body 220 and the core lid 222, and the core inner flow path 224 is a flow provided in the water discharge cylinder 280. It communicates with the path 282. The core body 220 and the core lid 222 are provided with introduction ports 232 and 234 that allow the core flow path 224 and the pressure chambers 216 and 218 to communicate with each other. The main valves 242 and 244 and the slide bars 246 and 248 are provided so as to cross the inner core flow path 224.

As illustrated in FIG. 7, when the main valve 244 moves in a direction away from the core body 220, the introduction port 234 is opened. On the other hand, when the main valve 242 moves away from the core body 220, the introduction port 232 is opened.
These inlets 232 and 234 are both in communication with the core inner channel 224. That is, the introduction port 232 communicates the pressure chamber 216 in the housing and the core inner flow path 224, and the introduction port 234 communicates the pressure chamber 218 and the core inner flow path 224.

  The operation of the main valves 242 and 244 for changing the opening degree of the introduction ports 232 and 234 is determined by the slide bars 246 and 248 installed coaxially. That is, as shown in FIGS. 5 and 6, the left and right slide bars 246 and 248 are connected with the compressed leaf spring 260 sandwiched therebetween, and are directed to the right end or the left end depending on the bending direction of the leaf spring 260. Receive a biasing force. The leaf spring 260 is supported by the core body 220 at both ends, and the slide bars 246 and 248 move relative to the core body 220 via the leaf spring 260. The main valves 242 and 244 receive this urging force from the slide bars 246 and 248, and control the introduction ports 232 and 234 to an alternative state of the fully open state or the fully closed state.

Next, the operation of the hydraulic drive device 2 will be illustrated.
FIG. 8 is a schematic diagram for illustrating the operation of the hydraulic drive device.
FIG. 6A shows a state in which the slide bars 246 and 248 are urged toward the left side by the action of the leaf spring 260. At this time, since the main valves 242 and 244 are also urged toward the left side by the slide bar 246, the introduction port 232 is closed and the introduction port 234 is open.

When the fluid W1 having substantially the same pressure is introduced into the water inlets 212 and 214 in this state, the water introduced into the pressure chamber 218 from the water inlet 214 as indicated by the arrow a is the inlet 234 as indicated by the arrow c. Flows into the core inner flow path 224 and flows out through the flow path 282 as indicated by the arrow d. On the other hand, the water introduced into the pressure chamber 216 from the water inlet 212 as indicated by the arrow b has no outflow path because the inlet 232 is closed, and increases the pressure in the pressure chamber 216.
That is, by providing a difference in the opening degree of the inlets 232 and 234, a difference occurs in the channel resistance and a pressure difference occurs. As a result, the pressure in the pressure chamber 216 becomes higher than that in the pressure chamber 218, and the core is pushed and moved in the direction of the arrow M.

  When the core body 220 moves in the direction of arrow M, the volume of the pressure chamber 216 increases, and the volume of the pressure chamber 218 decreases accordingly. Therefore, the fluid W1 in the pressure chamber 218 is pushed out by the amount of the fluid W1 flowing into the pressure chamber 216 through the path indicated by the arrow b, and is included in the water discharge amount of the fluid W1 flowing out from the flow path 282.

  When the core continues to move and the slide bar 248 comes into contact with the inner wall of the housing body 202 and is pressed against the core, the bending direction of the leaf spring 260 is reversed, as shown in FIG. 8B. Further, the slide bars 246 and 248 are biased toward the opposite side. Then, when the slide bar 248 pushes the main valve 244, the main valves 242, 244 are also moved to the right (clockwise direction). That is, the introduction port 232 is opened and the introduction port 234 is closed.

  In the state shown in FIG. 8B, the fluid W1 introduced into the pressure chamber 216 from the water inlet 212 as shown by the arrow b flows from the inlet 232 into the core inner flow as shown by the arrow c. It flows into the channel 224 and flows out through the channel 282 as indicated by the arrow d. On the other hand, as shown by the arrow a, the fluid W1 introduced into the pressure chamber 218 from the water inlet 214 has no outflow path because the inlet 234 is closed, and increases the pressure in the pressure chamber 218. . As a result, a pressure difference is generated in the pressure chambers 216 and 218, and the core starts moving toward the right side as indicated by an arrow M.

  When the core further moves, as shown in FIG. 8C, the slide bar 246 moves to a position where it abuts against the inner wall of the housing body 202. When the core further moves from this state and the slide bar 246 is pushed against the core, the bending direction of the leaf spring 260 is reversed and biased to the opposite side. Then, like the state shown in FIG. 8A, the introduction port 232 is closed and the introduction port 234 is opened, and the core starts moving toward the left side.

  That is, the hydraulic drive device 2 is connected to the water discharger 3 and can perform a repetitive motion of the water discharger 3 by flowing a predetermined amount or more of fluid (first state).

  Moreover, a speed adjusting mechanism (not shown) for adjusting the moving speed can be provided. Examples of the speed adjustment mechanism include a flow rate adjustment valve that adjusts the flow rate of the fluid W1 supplied to the hydraulic drive device 2, a bypass flow path provided between the pressure chamber 216 and the pressure chamber 218, and a sliding brake. can do.

  By providing such a speed adjusting mechanism, even if the moving speed varies due to manufacturing errors or the like, the desired moving speed can be obtained by adjustment. Note that the speed adjustment mechanism is for fine adjustment performed at the time of maintenance or shipping, and may be normally not used by the user of the shower apparatus 1.

  In addition, the hydraulic drive apparatus of this invention is not necessarily limited to what was illustrated in FIG. 5 thru | or FIG. For example, it is possible to provide a switching mechanism that connects the water discharger 3 that is repetitively movable and a water wheel that is rotated by hydraulic power via a reduction gear train to reverse the moving direction of the water discharger 3. As a switching mechanism, for example, a valve that moves to the left and right around a fulcrum and an inverter may be provided, and the closing side of the inlet port may be switched when the direction in which the valve falls is changed. In addition, for example, a piston provided in the cylinder is reciprocated linearly by water pressure, and the reciprocating linear motion of the piston is converted into a repetitive motion of the water discharger 3 using a link or a wire, and the moving direction of the water discharger 3 is switched. It can also be reversed by a mechanism. As the switching mechanism, for example, an introduction port switching mechanism provided in the above-described core can be used.

  An electric motor, a solenoid, or the like can be used as the switching mechanism. However, if such a water channel automatic switching mechanism using hydraulic power is used, a water discharge source and a repetitive motion power source are unified. Simplification of the mechanism can contribute to cost reduction and reliability improvement.

Next, returning to FIGS. 1 to 4, other elements provided in the shower device 1 will be illustrated.
A constant flow valve 5 is attached in the middle of the water supply flow path 16. The constant flow valve 5 is not always necessary and can be omitted. However, if the constant flow valve 5 is provided, when the shower device 1 is provided in a high water pressure environment, a function as a so-called limiter can be achieved. Therefore, it is preferable to provide the constant flow valve 5.

  Further, the flow rate control method of the constant flow valve 5 is not particularly limited and can be appropriately selected. For example, a rubber type that uses the elastic force of rubber to change the inner diameter of the orifice by differential pressure, a spring type that changes the inner diameter of the orifice by sliding the needle using the elastic force of a spring built into the needle, etc. It can be.

  The casing 6 is provided with a frame 6a to which the hydraulic drive device 2, the switching unit 4, the constant flow valve 5 and the like are attached, and a cover 6b for storing these and the piping member so as to cover them. For example, the frame 6a is attached to a wall surface such as a bathroom or a shower room, and the shower device 1 is fixed to the wall surface or the like via the frame 6a. The frame 6a and the cover 6b are preferably made of a corrosion-resistant material, and can be made of, for example, a synthetic resin or a corrosion-resistant metal such as stainless steel.

FIG. 9 is a schematic perspective view for illustrating the switching unit 4. In addition, the arrow in a figure represents the flowing water direction.
As shown in FIG. 9, the switching unit 4 is provided with a handle 10, a main body 11, a bearing 12, and a valve body 13.

  The main body 11 has an inflow port 11a and outflow ports 11b and 11c, and the constant flow valve 5 is connected to the inflow port 11a through a pipe. Moreover, the water discharge part 3 is connected to the outflow port 11b via the main channel 9b, and the hydraulic drive unit 2 is connected to the outflow port 11c via the drive unit channel 9a. Further, in the main body 11, the flow path communicating with the inflow port 11a is branched into two, and the branched flow paths communicate with the outflow ports 11b and 11c, respectively.

  The valve body 13 has a cylindrical shape, and a throttle 13a illustrated as a first flow rate control unit linearly penetrates the radial direction, and a throttle 13b illustrated as a second flow rate control unit has an L-shape in the radial direction. It is bent in a shape and penetrates (see FIGS. 12 and 13). As will be described later, by rotating the valve body 13, the cross-sectional area of the flow path is variable at the portion where the throttles 13a and 13b are provided.

  In the main body 11, a throttle 13a is provided on the flow path that connects the inlet 11a and the outlet 11b, and a throttle 13b is provided on the flow path that connects the inlet 11a and the outlet 11c. Yes. Therefore, the throttle 13b controls the flow rate of the fluid flowing through the drive unit flow path 9a by changing the flow path resistance, and the throttle 13a controls the flow rate of the fluid flowing through the main flow path 9b by changing the flow path resistance. Can be done.

  Although the throttles 13a and 13b are illustrated as examples of controlling the flow rate by changing the flow path resistance, the invention is not limited to this. It is possible to appropriately select one that can change the flow path cross-sectional area and change the flow path resistance to control the flow rate.

  Further, the flow paths provided across the throttle 13a that linearly penetrates the radial direction of the valve body 13 are provided so as to be on the same axis line, and the radial direction is bent in an L shape and penetrates. The flow paths provided across the aperture 13b are provided so that their axes are substantially orthogonal. Therefore, the flow paths provided with the valve body 13 interposed therebetween are communicated with each other via the throttle 13a and the throttle 13b.

The bearing 12 has an annular shape, and a valve body 13 is rotatably inserted into a hole provided on the center side. Further, the outer periphery of the bearing 12 is fitted into a hole provided in the main body 11. A holding body 14 (see FIG. 12) is slidably provided in the groove portion of the valve body 13, and the holding body 14 is fitted in a hole provided on the center side of the bearing 12. Therefore, the position of the valve body 13 in the axial direction is maintained, and the positions of the restrictors 13a and 13b and the flow path can be prevented from shifting.
One end of the valve body 13 protrudes from the main body 11, and a handle 10 is provided in the vicinity of the end surface.

  By rotating this handle 10 to rotate and move the position of the throttle 13b provided in the valve body 13, and changing the flow path cross-sectional area, the flow rate of the fluid flowing out to the drive section flow path 9a side can be controlled. It has become. And the hydraulic drive device 2 can be controlled by controlling the flow rate of the fluid flowing out to the drive unit flow path 9a side, and at the same time, the moving speed of the water discharge unit 3 can be adjusted or stopped. it can. As described above, since the drive and stop of the hydraulic drive device can be switched by one operation of the handle, it is easy to use.

  Here, the flow rate of the discharged water W2 discharged from the nozzle hole 3c is the sum of the flow rates of the fluid that has flowed through the drive unit flow path 9a and the main flow path 9b. Therefore, if only the outflow flow rate toward the drive unit flow path 9a is controlled, the amount and momentum of the water discharge W2 applied to the user may be reduced. Such unintended fluctuations in the flow rate or momentum of the discharged water W2 cause the user to feel uncomfortable or uncomfortable.

For this reason, in this embodiment, the flow rate of the fluid flowing out to the drive channel 9a side is controlled by rotating the valve body 13, and the flow rate of the fluid flowing out to the main channel 9b is also controlled. Can be done.
That is, the flow rate of the fluid flowing through the main flow path 9b is controlled by the throttle 13a so that the throttle 13b and the throttle 13a cooperate to cancel the change in flow rate caused by the control by the throttle 13b. Yes.

FIG. 10 is a schematic diagram for illustrating the flow rate control by the valve body 13. That is, FIG. 10A shows the case where the drive section flow path 9a side is fully opened (when the hydraulic drive device 2 is driven), and FIG. 10B shows the drive section flow path 9a side fully closed (closed). This is the case (when the drive of the hydraulic drive device 2 is stopped). In addition, the arrow in a figure represents the flowing water direction.
As shown in FIGS. 10 (a) and 10 (b), the switching unit 4 incorporates the valve body 13 described above, and by moving the valve body 13 in the rotational direction, the throttle amount on the drive unit flow path 9a side ( The flow path resistance value) and the amount of restriction on the main flow path 9b side (flow path resistance value) can be collectively controlled. Moreover, by having comprised in this way, there are few connection locations of piping and the compact structure is implement | achieved.

  As shown in FIG. 10 (a), when the hydraulic drive device 2 is driven (first state), the drive channel 9a side is fully opened so that the flow rate required for driving can be ensured, and the main channel 9b. The diaphragm of the channel on the side is throttled so that the throttle amount is A1. Although the hydraulic drive device 2 can be driven without being fully opened, it is assumed to be fully opened here for convenience of explanation.

  As described above, the fluid W1 introduced into the hydraulic drive device 2 is discharged from the nozzle hole 3c via the inlets 232 and 234 and the flow path 282. Therefore, the sum of the channel resistances on the side of the main channel 9b that is directly discharged from the nozzle hole 3c through the main channel 9b is larger than the sum of the channel resistances on the side of the drive unit channel 9a. There is a possibility that the flow rate of the fluid W1 flowing toward the partial flow path 9a is insufficient.

  In the present embodiment, the flow resistance of this portion is increased by narrowing the throttle on the main flow path 9b side, and the flow rate of the fluid flowing to the drive section flow path 9a side is ensured. In this case, the amount of restriction (the value of the channel resistance) is determined in consideration of the balance between the total channel resistance on the main channel 9b side and the total channel resistance on the drive unit channel 9a side. The total flow resistance refers to the total flow resistance between the branching section and the water discharge section 3 on the drive section flow path 9a side or the main flow path 9b side.

  That is, in this embodiment, the flow resistance of the main flow path is controlled so that the flow rate discharged from the water discharger is the same when the water discharger is repeatedly moved and when it is stopped. I am doing so. For example, when it is desired to repeatedly move the water discharger, the amount of water for driving the hydraulic drive unit 2 is supplied into the hydraulic drive unit, and further supplied to the main channel, so that the water discharge from the water discharger The flow rate is increased. On the other hand, when it is desired to stop the repetitive movement of the water discharger, hot water is not supplied to the hydraulic drive device 2 but the entire amount is supplied to the main flow path. At this time, the flow resistance discharged from the water discharger is prevented from decreasing by switching the flow resistance of the main flow path to be smaller than that when the water discharger is repeatedly moved. Therefore, the total flow resistance on the main flow path 9b side and the drive section flow path 9a are set so that the flow rate discharged from the water discharge section is the same when the water discharge section is repeatedly moved and when the water discharge section is stopped. The amount of restriction (the value of the channel resistance) is determined in consideration of the balance with the total channel resistance on the side.

  As shown in FIG. 10 (b), when the drive of the hydraulic drive device 2 is stopped (second state), the drive section flow path 9a side is fully closed (closed), and the flow path on the main flow path 9b side. The aperture is widened so that the aperture amount is A2. Therefore, even if the drive unit flow path 9a side is fully closed (closed), the flow rate of the fluid flowing through the main flow path 9b side is increased, so that the amount of water discharged from the nozzle hole 3c can be ensured. Even if it is not fully closed (closed), the hydraulic drive device 2 can be stopped due to frictional resistance, but for the sake of convenience of description, it is assumed to be fully closed (closed) here.

  In this case, the throttle amount (flow resistance value) is set such that the same amount of water discharged as when the hydraulic drive device 2 is driven (in the case of FIG. 10A) is discharged from the nozzle hole 3c. ing. That is, the sum of the flow rates Va and Vb of each flow path when the hydraulic drive device 2 is driven is the same as the flow rate Vc when the drive of the hydraulic drive device 2 is stopped (discharged from the nozzle hole 3c). The amount of restriction (the value of flow path resistance) is such that the amount of water discharged is the same.

  As described above, since the water discharge flow rate can be made substantially the same during repeated movement of the water discharge unit and when the water discharge unit is stopped, there is no need to perform troublesome flow adjustment when switching the exercise state of the water discharge unit, and the flow rate is There is no sense of incongruity due to change, and the continuity of the showering feeling can be maintained.

  Further, in order to adjust the speed of the hydraulic drive device 2, the throttle of the flow path on the main flow path 9 b side is also controlled when the flow path on the drive section flow path 9 a side is throttled (for example, when it is half open). The amount of water discharged from the nozzle hole 3c is set to be the same. That is, the throttle amount (the value of the channel resistance) on the drive unit channel 9a side so that the amount of water discharged from the nozzle hole 3c is the same regardless of whether or not the hydraulic drive device 2 is driven. ) And the amount of restriction (the value of the flow path resistance) on the main flow path 9b side are collectively controlled.

  In the present specification, the amount of water discharged from the nozzle hole 3c is constant and the same includes the case where there is a difference in flow rate that the user does not feel uncomfortable or uncomfortable. For example, the fluctuation width of the total flow rate discharged from the water discharge portion is within 20%, more preferably within 10%.

  In addition, the shower feeling tends to obtain a better feeling when the flow rate is higher, but it is possible to obtain a feeling of shower even with a lower flow rate by performing repetitive exercise. Although it is not limited to it as a discharged water flow rate, 9.5 L / min or less, More preferably, it is 8.0 L / min or less, More preferably, even if it is 6.5 L / min or less, sufficient bathing feeling can be acquired. . In this way, a water-saving effect can be obtained by repetitive motion.

  10 (a) and 10 (b), the valve body 13 is provided on the downstream side of the branch portion, but a so-called rotary type valve body (disc-shaped valve body) or a cylindrical valve is provided. A body (a plurality of throttle holes having different areas on the cylindrical surface) may be provided at the branch portion.

FIG. 11 is a schematic cross-sectional view for illustrating a case where a cylindrical valve body is provided at a branch portion. In addition, the arrow in a figure represents the flowing water direction.
As shown in FIG. 11, the main body 11 of the switching unit 4c is provided with outlets 11b and 11c. The water discharge part 3 is connected to the outflow port 11b via the main flow path 9b, and the hydraulic drive unit 2 is connected to the outflow port 11c via the drive part flow path 9a.
A valve body 73 is provided inside the main body 11. The valve body 73 has a cylindrical shape with one end closed. On the outer peripheral surface of the valve body 73, throttles 73a1 and 73a2 exemplified as the first flow rate control unit and a throttle 73b exemplified as the second flow rate control unit are opened. Further, the diaphragm 73a1 and the diaphragm 73a2 are provided so as to be separated from each other so that their axes are orthogonal to each other.
Further, by rotating the valve body 73, the flow path cross-sectional area is variable in the portions where the throttles 73a1, 73a2, and 73b are provided. Therefore, the restrictor 73b controls the flow rate of the fluid flowing through the drive unit passage 9a by changing the passage resistance, and the restrictor 73a1 or the restrictor 73a2 controls the flow of the fluid flowing through the main passage 9b by changing the passage resistance. The flow rate can be controlled.
In the present embodiment, the valve body 73 also serves as a branch portion.

11A shows a case where the hydraulic drive device 2 is caused to perform repetitive motion, and FIG. 11B shows a case where the repetitive motion of the hydraulic drive device 2 is stopped.
As shown to Fig.11 (a), when making the hydraulic drive device 2 perform repetitive motion, it is made for the inside of the valve body 73 and the outflow port 11c to communicate with each other via the aperture 73b. At this time, the inside of the valve body 73 and the outflow port 11b are communicated with each other through the throttle 73a2, and the fluid is also supplied to the water discharger 3.
As shown in FIG. 11B, when the repetitive motion of the hydraulic drive device 2 is stopped, the valve body 73 is rotated so that the communication between the inside of the valve body 73 and the outlet 11c is blocked. . At this time, the inside of the valve body 73 and the outlet 11b are communicated with each other via a throttle 73a1 having a larger area than the throttle 73a2 so that the supply of fluid to the water discharger 3 is not blocked.
And the amount of water discharged in the state (first state) where water is discharged while repetitively moving the hydraulic drive device 2 is the same as the state (second state) where water is discharged while the hydraulic drive device 2 is stopped. As described above, the aperture areas of the diaphragm 73a1 and the diaphragms 73a2 and 73b are respectively set. In addition, even if it does not interrupt | block the communication between the inside of a valve body and the outflow port 11c, since there exists friction resistance etc., the drive of the hydraulic drive unit 2 can be stopped, but here, for convenience of explanation, it interrupts | blocks here. (Clogged).

  Further, the flow path resistance in the valve body 13 and the valve body 73 can be changed continuously. This is preferable because the amount of water discharged can be made constant during switching between the state in which the shower water discharger is repeatedly moved and the state in which the shower water discharger is stopped. Further, the speed of the hydraulic drive device 2 can be easily adjusted.

That is, the states of the valve body 13 and the valve body 73 of the switching unit 4 are the states shown in FIGS. 10 (a) and 11 (a) (the water discharge section 3 moves repeatedly), FIGS. 10 (b) and 11 (b). ) (The water discharger 3 stops), but it is more preferable to form an intermediate state between the two states in order to ensure the continuity of the switching operation. For example, an intermediate state can be formed by providing a plurality of diaphragms 13a and a plurality of diaphragms 13b so that the sectional area of the diaphragm 13b decreases and the sectional area of the diaphragm 13a increases. Furthermore, by configuring each of the throttle 13a and the throttle 13b as one hole whose sectional area continuously changes in the rotation direction of the valve body 13, more continuity can be ensured. In this intermediate state, the flow rate of water discharged from the water discharger 3 can be secured further and the speed of repetitive motion can be adjusted. That is, by fixing the operation handle 10 in an intermediate state, the user can take a bath adjusted to his / her favorite speed while maintaining a constant flow rate to be discharged.
Further, by keeping the flow rate constant, it is possible to prevent the temperature of the hot water discharged from the water discharger from changing unintentionally without being affected by the hot water supply capability (ignition determination).
Thus, the continuity of the switching operation can be further ensured by configuring the flow path resistance in the valve body 13 to change continuously. That is, the repetitive motion of the water discharger can be changed smoothly, and the flow rate and hot water temperature discharged from the water discharger can be kept constant. Therefore, the continuity of the shower feeling can be further maintained during the switching operation.

FIG. 12 is a schematic diagram for illustrating the position of the valve body when the hydraulic drive device is driven.
FIG. 13 is a schematic view for illustrating the position of the valve body when the drive of the hydraulic drive device is stopped. FIGS. 12 and 13 are views showing the cross-section taken along the line CC in FIG. 9 in each case.

  FIG. 12 shows a case where the hydraulic drive device 2 is driven, that is, a case illustrated in FIG. As shown in FIG. 12, when the hydraulic drive device 2 is driven, a throttle 13b provided on the flow path connecting the inflow port 11a and the outflow port 11c is provided so as to ensure a flow rate necessary for driving. “Fully open”. That is, the flow path resistance is minimized by matching the axis of the throttle 13b with the axis of the flow path communicating with the throttle 13b. In addition, the outer peripheral surface 13c of the valve body 13 in the portion where the throttle 13a is provided is configured to block a part of the channel cross section 15 on the main channel 9b side to provide channel resistance. In this case, in the portion where the throttle 13a is provided, a part of the outer peripheral surface 13c is cut out, and the fluid flows through this portion.

  FIG. 13 shows a case where the driving of the hydraulic drive device 2 is stopped, that is, a case illustrated in FIG. As shown in FIG. 13, when the drive of the hydraulic drive device 2 is stopped, the throttle 13b provided on the flow path connecting the inflow port 11a and the outflow port 11c is set to the “fully closed (closed) state”. . That is, the communication between the inflow port 11a and the outflow port 11c is blocked at the outer peripheral surface of the valve body 13 in the portion where the throttle 13b is provided. In this case, since the throttle 13b is bent in an L shape, the communication between the inlet 11a and the outlet 11c is blocked by the portion of the outer peripheral surface where the throttle 13b is not open.

  In addition, the throttle 13a provided on the flow path connecting the inflow port 11a and the outflow port 11b is in a “fully open state”. That is, the axis of the throttle 13a and the axis of the flow path communicating with the throttle 13a are matched. Therefore, even if the throttle 13b is fully closed (closed) and the outflow to the drive unit flow path 9a is stopped, the flow rate of the fluid flowing through the main flow path 9b increases, so the amount of water discharged from the nozzle hole 3c is reduced. Can be secured.

Even when the aperture 13a is in the “fully open state”, the aperture size is such that a predetermined flow path resistance value (aperture amount) is given. In this case, the flow path resistance value (throttle amount) given by setting the throttling 13a to the “fully open state” is the same amount of water discharge as when the hydraulic drive device 2 is driven (in the case of FIG. 12). It is a value which is performed from the nozzle hole 3c.
In addition, if the switching unit 4 is arrange | positioned downstream from a branch part or a branch part, flow volume adjustment can be made easy. Further, if the switching unit 4 is arranged at the branch portion, the configuration can be made more compact.

The piping that forms the flow path to the shower device 1 is provided with a temperature control valve 8 and a water stop valve 7 in order from the upstream side. In addition, a water supply pipe 16 a and a hot water supply pipe 16 b are connected to the temperature control valve 8. The water stop valve 7 controls the inflow of the fluid W1 into the shower device 1 by opening and closing the flow path. The temperature control valve 8 adjusts the temperature of the fluid W1 that flows into the shower device 1 by mixing the supplied water and hot water and changing the mixing ratio.
In addition, the form of the water stop valve 7 and the temperature control valve 8 is not specifically limited, It can select suitably. Further, the water stop valve 7 may be provided on the upstream side of the temperature control valve 8, or the temperature control valve 8 may have the function of the water stop valve 7. In addition, at least one of the water stop valve 7 and the temperature control valve 8 can be incorporated in the shower device 1.
Moreover, the water stop valve 7 may have a flow control function.

Next, the operation of the shower device 1 will be illustrated.
FIG. 14 is a schematic cross-sectional view for illustrating the operation of the shower device 1.
A fluid W1 (hot water) whose temperature has been adjusted by a temperature control valve 8 (not shown) is introduced into a constant flow valve 5 provided in a water inlet of the shower device 1. The fluid W1 introduced into the constant flow valve 5 flows out toward the switching unit 4. The fluid W1 flowing out from the constant flow valve 5 is introduced into the main body 11 of the switching unit 4 from the inflow port 11a. The fluid W1 introduced into the main body 11 flows out from the outlets 11b and 11c through the two branched channels.
At this time, the switching unit 4 can switch the driving and stopping of the hydraulic drive device 2 and adjust the speed.

  In addition, as described above, the amount of restriction on the drive channel 9a side (so that the amount of water discharged from the nozzle hole 3c is the same regardless of whether or not the hydraulic drive device 2 is driven and the speed) The flow resistance value) and the amount of restriction on the main flow path 9b side (flow resistance value) are collectively controlled. In this case, the amount of restriction (the value of the flow path resistance) is controlled by moving the valve body 13 provided with the restriction 13a and the restriction 13b in the rotation direction, so that the flow passage cross-sectional area of the restriction portion (the restriction 13a and the restriction 13b). By changing.

The fluid W1 flowing out from the outflow port 11b is introduced into the water discharger 3, and is discharged outward from the nozzle hole 3c provided in the nozzle plate 3b.
The fluid W1 flowing out from the outflow port 11c is introduced into the hydraulic drive device 2 through the drive unit flow path 9a. The fluid W <b> 1 introduced into the hydraulic drive device 2 flows out toward the water discharge unit 3 after driving the hydraulic drive device 2. In addition, about the effect | action of the hydraulic drive device 2, since it is the same as that of what was illustrated in FIG. 8, the description is abbreviate | omitted.
And the fluid W1 which flowed out from the hydraulic drive unit 2 and was introduced into the water discharge part 3 is also discharged toward the outside from the nozzle hole 3c provided in the nozzle plate 3b.

  The user can switch between a repetitive motion state and a stopped state of the water discharger by operating the handle 10 and rotating the valve body. At this time, since the water discharge flow rate can be made substantially the same, there is no need to perform troublesome flow rate adjustment when switching the exercise state, and there is no sense of incongruity due to the change in flow rate, and continuity of the showering feeling can be ensured.

  Thus, by reducing the flow rate supplied to the hydraulic drive unit 2, the fluid force acting on the core is reduced, the core is stopped, and the repetitive motion of the water discharger 3 can be stopped reliably. In addition, since the flow rate through the hydraulic drive unit 2 is reduced, problems due to water quality (small sand and dust) are less likely to occur, and a highly reliable system can be constructed. In the valve body 13, the switching of the flow path and the control of the flow rate are performed, and a compact configuration is realized. The fluid force acting on the core is a force acting on the core to move the core, and is a force resulting from the static pressure, dynamic pressure, or flow of the fluid.

  Moreover, since the fluid force is reduced, the user can manually move the watering direction of the water discharger 3 in a state where the water discharger 3 is stopped. Thereby, in the stop state, the user can accurately position the water discharge to the part to be applied. At this time, the core and the water discharger 3 remain connected and move in conjunction with each other. That is, no matter how the user manually adjusts the position of the water discharger 3, the connection relationship with the core continues. Therefore, when the repetitive motion of the water discharger 3 is resumed, there are no problems such as poor connection, it takes time to resume, and the center position of the motion is shifted, and the repetitive motion state can be reproduced smoothly and accurately.

  At this time, in the case of a hydraulic drive device in which pressure chambers are provided on both sides across the core, a damper effect works on the core by hot water in the pressure chamber, so when manually moving the water discharger 3, Positioning is easy without abrupt movement, and an appropriate operational feeling is obtained, which is more preferable. Moreover, since the movement of the core is slower than that of the water wheel, a speed reduction mechanism such as a multistage gear is not required, and the power transmission unit is simplified. Therefore, the torque required for manually moving the shower unit is small and more preferable.

Further, even in the process in which the handle 10 is operated to change the motion state of the water discharger, it is more preferable that the water discharge is continuously maintained and the continuity can be maintained. For example, the flow path resistance in the valve body 13 is configured to change continuously. At this time, the fluid force acting on the core is adjusted, and the movement speed of the water discharger can be controlled, so that the user's preference can be met.
Moreover, according to this Embodiment, a very compact shower apparatus can be comprised.

FIG. 15 is a schematic diagram for illustrating the configuration of the shower device according to the second embodiment of the invention.
FIG. 16 is a schematic perspective view for illustrating the appearance of the shower device according to the present embodiment.
FIG. 17 is a schematic exploded view of the shower apparatus illustrated in FIG.
As shown in FIGS. 15 to 17, the shower device 30 includes a hydraulic drive device 32, a water discharger 33, a switching unit 4 or 4 c in which the valve body 13 or the valve body 73 is built, a housing 36, and a link. A mechanism 37, a support body 38, and a speed adjustment mechanism 39 are provided. In addition, a water stop valve 7 and a temperature control valve 8 are provided in a pipe that forms a flow path to the shower device 30. And these are connected by piping, and fluids, such as hot water supplied to the water inlet of the temperature control valve 8, can be discharged from the nozzle hole 33c of the water discharger 33 as water discharge W2 (shower water discharge).
In the present embodiment, the switching unit 4 serves as a branching part that branches the flow path into the main channel 9b and the drive part channel 9a. However, the switching unit 4 is provided downstream of the branching part instead of the branching part. You can also.

As shown in FIGS. 16 and 17, the water discharger 33 is a rectangular parallelepiped main body 3 having a space inside.
3a and a nozzle plate 33b provided on the front surface of the main body 33a and having a plurality of nozzle holes 33c. A space (not shown) provided inside the main body 33a communicates with the nozzle hole 33c.

  A hole 33f having a circular cross section is provided in the axial end surface of the main body 33a, and the support portion 31 provided in the switching unit 4 is mounted in the hole 33f provided in one axial end surface so as to be liquid-tight. In the hole 33f provided in the end surface in the axial direction, the outflow part 38a of the support body 38 provided with a flow path is mounted so as to be liquid-tight. In this case, the inside of the support 38 serves as a part of the second drive unit flow path that communicates from the hydraulic drive unit 32 to the water discharge unit 33.

  The main body 33a is held repetitively by the support portion 31 and the support body 38 attached to the hole 33f, and the fluid W1 is provided inside the water discharge portion 33 through the outflow portion 38a of the support body 38. It is possible to flow into a space (not shown). Further, the fluid W1 that has flowed into a space (not shown) can be discharged from the nozzle hole 33c as discharged water W2.

  In the hydraulic drive device 32, the core shafts 32a and 32b are protruded on both sides of the housing, and one of the shafts 32a is provided with a flow passage (not shown) in the same manner as the water discharge cylinder 280, and the other shaft 32b. Is not provided with a flow path. A flow path (not shown) provided on the shaft 32a and a flow path (not shown) provided on the support 38 are connected by a pipe (not shown). The other shaft 32 b is mechanically coupled to the link mechanism 37 so that the driving force of the hydraulic drive device 32 is transmitted to the link mechanism 37. Further, the water discharger 33 and the hydraulic drive device 32 are connected via a link mechanism 37. In addition, since the other structure and effect | action of the hydraulic drive apparatus 32 are the same as that of the hydraulic drive apparatus 2 mentioned above, the description is abbreviate | omitted.

  The switching unit 4 includes a support portion 31 on its end surface, and the flow path formed in the inside thereof communicates with the inside of the water discharger 33 to form the main flow path 9b. The housing 36 is provided with a frame 36a to which the hydraulic drive device 32, the switching unit 4, the support 38, the speed adjustment mechanism 39, and the like are attached, and a cover 36b that covers and accommodates these and piping members. . The frame 36a is attached to a wall surface such as a bathroom or a shower room, and the shower device 30 is fixed to the wall surface or the like via the frame 36a. The frame 36a and the cover 36b are preferably made of a corrosion-resistant material, and can be made of, for example, a corrosion-resistant metal such as a synthetic resin or stainless steel.

  As described above, the link mechanism 37 is mechanically connected to the shaft 32b and the output side is mechanically connected to the main body 33a. Further, a part of the link mechanism 37 may be provided with a single-stage or multi-stage gear train. In this case, the water discharger 33 can be smoothly and repeatedly moved even when the hydraulic power is weak.

  The support body 38 is provided with an outflow portion 38a and an inflow portion 38b, and an opening provided in the end surface of the outflow portion 38a and an opening provided in the end surface of the inflow portion 38b communicate with each other inside the support body 38. A non-flow channel is provided. Further, as described above, the main body 33a is held by the outflow portion 38a so as to be capable of repetitive movement.

  The speed adjustment mechanism 39 is provided in the drive unit flow path 9 a and is for adjusting the speed of the hydraulic drive device 32 by adjusting the flow rate of the fluid supplied to the hydraulic drive device 32. If the speed adjusting mechanism 39 is provided, even if there is a variation in speed due to a manufacturing error or the like, the speed can be adjusted to a desired speed. As the speed adjustment mechanism 39, for example, a speed adjustment valve having a throttle valve or the like inside can be used. However, the present invention is not limited to this, and can be changed as appropriate. Further, the speed adjustment mechanism 39 is used for fine adjustment performed at the time of maintenance or shipping, and may not be normally used by the user of the shower device 30.

In addition, the constant flow valve 5 illustrated in FIG. 1 can be provided as appropriate. The speed adjusting mechanism 39 and the constant flow valve 5 are not always necessary and can be omitted.
The operation of the shower device 30 is the same as that of the shower device 1 described above, and a description thereof will be omitted.

For example, although a swing is cited as an example of repetitive motion, a reciprocating linear motion as disclosed in Patent Document 1 may be used.
Moreover, although the case where the fluid which flowed out from the hydraulic drive unit was directly supplied to the water discharge unit was illustrated, the fluid which flows out from the hydraulic drive unit may be indirectly supplied to the water discharge unit. For example, you may make it supply the fluid which flowed out from the hydraulic drive unit to the water discharging part via the main flow path. In this case, the flow path of the fluid that has flowed out of the hydraulic drive device may be communicated with the main flow path on the downstream side of the position where the valve element is provided.

Also in this embodiment, the same effect as that illustrated in FIG. 1 can be obtained. For example, the main body in a state where the hydraulic drive device 32 is driven and water is discharged while the main body 33 is repetitively moved (first state) and in a state where water is discharged from the main body 33 while the hydraulic drive device 32 is stopped (second state). The amount of water discharged from 33 can be made the same. Further, since the water discharge flow rate can be made substantially the same, there is no need to perform troublesome flow rate adjustment when switching the exercise state, and there is no sense of incongruity due to the change in flow rate, and continuity of the showering feeling can be ensured. Further, by keeping the flow rate constant, it is possible to prevent the temperature of the hot water discharged from the water discharger from changing unintentionally without being affected by the hot water supply capability (ignition determination). That is, the repetitive motion of the water discharger can be changed smoothly, and the flow rate and hot water temperature discharged from the water discharger can be kept constant. Therefore, the continuity of the shower feeling can be further maintained during the switching operation. Since the fluid force acting on the core is reduced by reducing the flow rate supplied to the hydraulic power drive device 32, the user can manually move the water spraying direction of the water discharger 33 while the water discharger 33 is stopped. it can. Further, since the switching of the flow path and the control of the flow rate are performed in the valve body, a compact configuration can be realized.
Further, in the case of a hydraulic drive device in which pressure chambers are provided on both sides of the core, a damper effect is exerted on the core by the hot water in the pressure chamber. Therefore, when the water discharger 33 is moved manually, Positioning is easy without any movement, and an appropriate operational feeling can be obtained. Moreover, since the movement of the core is slower than that of the water wheel, the power transmission unit is simplified. Therefore, the torque required to manually move the shower unit is reduced. Moreover, according to this Embodiment, a very compact shower apparatus can be comprised.

Next, the case where the fluid that has flowed out of the hydraulic drive device is supplied to the water discharger indirectly, specifically, the case where it is supplied to the water discharger via the main channel will be illustrated.
FIG. 18 is a schematic view for illustrating the configuration of the shower device according to the third embodiment of the invention.
FIG. 19 is a schematic exploded view for illustrating the appearance of the shower device according to the present embodiment. Components similar to those illustrated in FIGS. 15 and 17 are denoted by the same reference numerals, and detailed description thereof is omitted as appropriate.
As shown in FIGS. 18 and 19, the shower device 40 includes a hydraulic drive device 42, a water discharge unit 33, a switching unit 4 in which the valve body 13 or the valve body 73 is built, a housing 36, and a link mechanism 37. And a support 48. In addition, a water stop valve 7 and a temperature control valve 8 are provided in a pipe that forms a flow path to the shower device 40. And these each component is connected by piping. Therefore, fluid such as hot water supplied to the water inlet of the temperature control valve 8 can be discharged from the nozzle hole 33c of the water discharger 33 as water discharge W2 (shower water discharge). In the present embodiment, the switching unit 4 serves as a branching part that branches the flow path into the main channel 9b and the drive part channel 9a. However, the switching unit 4 is provided downstream of the branching part instead of the branching part. You can also.

A hole 33f having a circular cross section is provided on the axial end surface of the main body 33a provided in the water discharger 33. An outflow portion 45b, which will be described later, is mounted in a hole 33f provided on one axial end face so as to be liquid-tight.
Further, the support portion 48a of the support body 48 is mounted in a hole 33f provided in the other axial end surface so as to be liquid-tight. Note that the hole 33f on the side where the support portion 48a is mounted need not be connected to a space (not shown) inside the main body 33a. In this case, the hole 33f on the side where the support portion 48a is mounted can be provided with a lid at the bottom. Further, when the hole 33f and a space (not shown) inside the main body 33a are not connected, it is not necessary to mount the support portion 48a so as to be liquid-tight.

  Further, the main body 33a is held by the outflow portion 45b and the support portion 48a attached to the hole 33f so as to be able to repeatedly move. Further, the fluid W1 can flow into a space (not shown) provided inside the main body 33a through the outflow portion 45b. And the fluid W1 which flowed into the space which is not shown in figure can be discharged from the nozzle hole 33c as the discharged water W2.

  A core shaft 42 b protrudes from one end face of the hydraulic drive device 42. The shaft 42b is provided with a flow path (not shown) inside, similar to the water discharge cylinder 280 described above. The shaft 42b is mechanically coupled to the link mechanism 37. Therefore, the driving force of the hydraulic drive device 42 is transmitted to the link mechanism 37. In addition, the water discharger 33 and the hydraulic drive device 42 are connected via a link mechanism 37. In addition, since the other structure and effect | action of the hydraulic drive unit 42 are the same as that of the hydraulic drive unit 2 mentioned above, the description is abbreviate | omitted.

On the end face of the switching unit 4, a merging portion 45 is provided.
A flow path is formed inside the merging portion 45. The flow path formed inside the merging portion 45 is connected to the flow path formed in the switching unit 4. In the present embodiment, the flow path formed inside the merging portion 45 forms the main flow path 9b.
In addition, the merging portion 45 is provided with an inflow portion 45a and an outflow portion 45b. The end surfaces in the axial direction of the inflow portion 45a and the outflow portion 45b are opened, and each is connected to a flow path formed inside the confluence portion 45.
Moreover, the inflow part 45a and the axis | shaft 42b are connected by piping which is not shown in figure. In the present embodiment, the flow path formed by connecting the inflow portion 45a and the shaft 42b becomes the drive portion flow path 19 (second drive portion flow path). Therefore, the merging portion 45 can join the main channel 9 b and the drive unit channel 19 on the upstream side of the water discharger 33.
If the junction portion 45 is provided as in the present embodiment, the connection portion of the flow path to the main body 33a can be reduced. Therefore, the sliding resistance at the connection portion can be reduced. Moreover, the load of the hydraulic drive device 42 can be reduced, and the hydraulic drive device 42 can be downsized and the shower device 40 can be downsized.

  The housing 36 is provided with a frame 36a to which the hydraulic drive device 42, the switching unit 4, the support body 48, the joining portion 45, and the like are attached. Further, a cover 36b is provided to cover these and the piping members so as to be accommodated. The frame 36a is attached to a wall surface such as a bathroom or a shower room, for example. And the shower apparatus 40 is fixed to a wall surface etc. via the frame 36a. The frame 36a and the cover 36b are preferably made of a corrosion resistant material. For example, it can be a corrosion resistant metal such as a synthetic resin or stainless steel.

  As described above, the link mechanism 37 is mechanically coupled to the shaft 42b on the input side. The output side is mechanically connected to the main body 33a. Further, a part of the link mechanism 37 may be provided with a one-stage or multi-stage gear train. By doing so, it is possible to cause the water discharger 33 to perform a smooth repetitive motion even when the hydraulic power is weak.

In addition, the constant flow valve 5 illustrated in FIG. 1 can be provided as appropriate. The constant flow valve 5 is not always necessary and can be omitted.
The operation of the shower device 40 is the same as that of the shower device 1 described above, and the description thereof is omitted.

Also in this embodiment, the same effect as that illustrated in FIG. 1 can be obtained. For example, the main body in a state where the hydraulic drive device 42 is driven to discharge water while the main body 33 is repeatedly moved (first state) and a state where water discharge is performed from the main body 33 while the hydraulic drive device 42 is stopped (second state). The amount of water discharged from 33 can be made the same. Further, since the water discharge flow rate can be made substantially the same, there is no need to perform troublesome flow rate adjustment when switching the exercise state, and there is no sense of incongruity due to the change in flow rate, and continuity of the showering feeling can be ensured. Further, by keeping the flow rate constant, it is possible to prevent the temperature of the hot water discharged from the water discharger from changing unintentionally without being affected by the hot water supply capability (ignition determination). That is, the repetitive motion of the water discharger can be changed smoothly, and the flow rate and hot water temperature discharged from the water discharger can be kept constant. Therefore, the continuity of the shower feeling can be further maintained during the switching operation. Since the fluid force acting on the core is reduced by reducing the flow rate supplied to the hydraulic drive unit 42, the user can manually move the water spraying direction of the water discharger 33 while the water discharger 33 is stopped. it can. Further, since the switching of the flow path and the control of the flow rate are performed in the valve body, a compact configuration can be realized.
Further, in the case of a hydraulic drive device in which pressure chambers are provided on both sides of the core, a damper effect is exerted on the core by the hot water in the pressure chamber. Therefore, when the water discharger 33 is moved manually, Positioning is easy without any movement, and an appropriate operational feeling can be obtained. Moreover, since the movement of the core is slower than that of the water wheel, the power transmission unit is simplified. Therefore, the torque required to manually move the shower unit is reduced.
Moreover, according to this Embodiment, a very compact shower apparatus can be comprised.

FIG. 20 is a schematic view for illustrating the configuration of the shower device according to the fourth embodiment of the invention.
As shown in FIG. 20, the shower device 50 includes a hydraulic drive device 2, a water discharge unit 3, a switching unit 4 a, a switching unit 4 b, an interlocking mechanism 24, a constant flow valve 5, and a housing 6. I have. In addition, a water stop valve 7 and a temperature control valve 8 are provided in the piping that forms the water supply flow path 16 to the shower device 50. The water supply flow path 16 branches into a drive section flow path (first drive section flow path) 9a that reaches the hydraulic drive device 2 via the branch section 16c and a main flow path 9b that reaches the water discharge section 3. Furthermore, a flow path (second drive section flow path) 282 that communicates with the hydraulic drive device 2 and the water discharge section 3 is provided. Fluid such as hot water supplied to the water inlet of the temperature control valve 8 can be discharged from the nozzle hole 3c of the water discharger 3 as water discharge W2 (shower water discharge).

The switching unit 4a and the switching unit 4b are connected by an interlocking mechanism 24. The switching units 4a and 4b can control flow rate as well as switching between water flow and water stop. Further, the switching unit 4a is provided in the first drive section flow path 9a downstream from the branch section, and the switching unit 4b is provided in the main flow path 9b downstream from the branch section. Then, by rotating a handle (not shown), the interlocking mechanism 24 connected to the handle is switched, and the flow rate of the fluid supplied to the first drive unit flow path 9a on the downstream side of the branch portion, and the branch portion The flow rate of the fluid supplied to the main flow path 9b on the more downstream side is controlled.
In this case, the switching unit 4a can also be disposed in the second drive section flow path. However, if the switching unit 4a is arranged in the first drive section flow path 9a downstream from the branch section, the load due to the water pressure applied to the hydraulic drive device 2 when the repetitive motion of the water discharge section 3 is stopped is reduced. be able to.

  When a predetermined amount of fluid is supplied, the hydraulic drive device 2 repeatedly moves the main body of the water discharger 3. That is, the water discharger 3 discharges water while performing repetitive motion. In the present embodiment, as will be described in detail later, by switching the switching unit 4a, it is possible to stop the driving of the hydraulic drive device 2. Furthermore, by controlling the switching unit 4b together with the switching unit 4a by the interlock mechanism 24, the hydraulic drive device 2 is driven to discharge water while the water discharger 3 is repetitively moved (first state), and the hydraulic drive device 2 is controlled. The amount of water discharged from the water discharger 3 in the state (second state) of water discharge from the water discharger 3 while being stopped can be made the same. These points will be described in detail later. In the first state and the second state, hot water is discharged from the same nozzle hole.

FIG. 21 is a schematic perspective view for illustrating the switching unit 4a. In addition, the arrow in a figure represents the flowing water direction.
As shown in FIG. 21, the switching unit 4a is provided with a main body 11, a bearing 12a, and a valve body 53.

  The main body 11 has an inflow port 11a and outflow ports 11c and 11e, and the constant flow valve 5 is connected to the inflow port 11a through a pipe. Moreover, the hydraulic drive device 2 is connected to the outflow port 11c through the drive part flow path 9a. Moreover, the switching unit 4b mentioned later is connected to the outflow port 11e. In addition, in the main body 11, the flow path communicating with the inflow port 11a is branched into two, and the branched flow paths communicate with the outflow ports 11c and 11e, respectively.

The valve body 53 has a cylindrical shape, and the throttle 13b is bent in the L shape in the radial direction and penetrates. As will be described later, by rotating the valve body 53, the cross-sectional area of the flow path is variable at the portion where the throttle 13b is provided.
In the main body 11, a throttle 53b is provided on a flow path that connects the inflow port 11a and the outflow port 11c (see FIG. 24). Therefore, the restrictor 53b can control the flow rate of the fluid flowing through the drive unit flow path 9a by changing the flow path resistance.

In addition, although the throttle 53b was illustrated as what controls flow volume by changing channel resistance, it is not necessarily limited to this. It is possible to appropriately select one that can change the flow path cross-sectional area and change the flow path resistance to control the flow rate.
In addition, the flow path provided with the diaphragm 53b penetrating through the valve body 53 bent in an L shape in the radial direction is provided so that the axes thereof are substantially orthogonal to each other. Therefore, the flow paths provided with the valve body 53 interposed therebetween are communicated with each other via the throttle 53b.

The bearing 12a has an annular shape, and a valve body 53 is rotatably inserted in a hole provided on the center side. Further, the outer periphery of the bearing 12 a is fitted into a hole provided in the main body 11. A holding body (not shown) is slidably provided in the groove 53c (see FIG. 24 (a)) of the valve body 53, and the holding body (not shown) is fitted into a hole provided on the center side of the bearing 12a. ing. Therefore, the axial position of the valve body 53 is maintained, and the positions of the throttle 53b and the flow path can be prevented from shifting.
One end of the valve body 53 protrudes from the main body 11, and a gear 24a is provided in the vicinity of the end surface.

  When the gear 24a is rotated, the position of the throttle 53b provided in the valve body 53 is rotationally moved, the flow passage cross-sectional area is changed, and the flow rate of the fluid flowing out to the drive portion flow passage 9a side is controlled. It has become so. And the hydraulic drive device 2 can be controlled now by controlling the flow volume of the fluid which flows out to the drive part flow path 9a side. The gear 24a and the gear 24b provided on the switching unit 4b side serve as the interlocking mechanism 24. The interlocking mechanism 24 will be described later.

FIG. 22 is a schematic perspective view for illustrating the switching unit 4b. In addition, the arrow in a figure represents the flowing water direction.
As shown in FIG. 22, the switching unit 4b is provided with a main body 11, a bearing 12b, and a valve body 23.

The main body 11 has an inlet 11d and an outlet 11b, and the outlet 11e of the switching unit 4a is connected to the inlet 11d via a pipe. Moreover, the water discharge part 3 is connected to the outflow port 11b via the main flow path 9b.
The valve body 23 has a cylindrical shape, and the throttle 23a penetrates the radial direction linearly. As will be described later, by rotating the valve body 23, the cross-sectional area of the flow path is variable at the portion where the throttle 23a is provided.
In the body 11, a throttle 23 a is provided on the flow path that connects the inlet 11 d and the outlet 11 b. Therefore, the throttle 23a can control the flow rate of the fluid flowing through the main flow path 9b by changing the flow path resistance.

In addition, although the throttle 23a was illustrated as what controls flow volume by changing channel resistance, it is not necessarily limited to this. It is possible to appropriately select one that can change the flow path cross-sectional area and change the flow path resistance to control the flow rate.
Further, the flow paths provided across the throttle 23a that linearly penetrates the radial direction of the valve body 23 are provided so as to be on the same axis line. Therefore, the flow paths provided with the valve body 23 interposed therebetween communicate with each other via the throttle 23a.

The bearing 12b has an annular shape, and a valve body 23 is rotatably inserted into a hole provided on the center side. Further, the outer periphery of the bearing 12 b is fitted in a hole provided in the main body 11. A holding body (not shown) is slidably provided in the groove 23c (see FIG. 24 (b)) of the valve body 23, and the holding body (not shown) is fitted into a hole provided on the center side of the bearing 12b. ing. Therefore, the position of the valve body 23 in the axial direction is maintained, and the positions of the throttle 23a and the flow path can be prevented from shifting.
One end of the valve body 23 protrudes from the main body 11, and a gear 24b is provided in the vicinity of the end surface. The gear 24b and the gear 24a provided on the switching unit 4a side mesh with each other.
In the present embodiment, the gear 24a and the gear 24b serve as the interlocking mechanism 24. However, the interlocking mechanism 24 is not limited to this. For example, another mechanical interlocking mechanism such as a link or a wire can be used, or an electrical interlocking such that a motor or a solenoid is provided in each of the valve bodies 53 and 23, and these are interlocked with an electrical signal. It can also be a mechanism. That is, the interlocking mechanism 24 only needs to interlock the switching unit 4a and the switching unit 4b. Further, the switching unit 4b may operate in conjunction with the operation of the switching unit 4a, or the switching unit 4a may operate in conjunction with the operation of the switching unit 4b. The operation handle may be connected to any of the switching unit 4a, the interlocking mechanism, or the switching unit 4b.
Further, by selecting the number of gear teeth, the link lever ratio, the rotation angle of the motor, and the like, the rotation angles of the valve bodies 53 and 23 can be made appropriate.

By rotating the gear 24b, the position of the throttle 23a provided in the valve body 23 is rotationally moved, the flow passage cross-sectional area is changed, and the flow rate of the fluid flowing out to the main flow passage 9b side is controlled. It has become. And the flow volume of the fluid supplied to the water discharging part 3 can be controlled now by controlling the flow volume of the fluid which flows out to the main flow path 9b side.
Here, the flow rate of the discharged water W2 discharged from the nozzle hole 3c is the sum of the flow rates of the fluid that has flowed through the drive unit flow path 9a and the main flow path 9b. Therefore, if only the outflow flow rate toward the drive unit flow path 9a is controlled, the amount and momentum of the water discharge W2 applied to the user may be reduced. Such unintended fluctuations in the flow rate or momentum of the discharged water W2 cause the user to feel uncomfortable or uncomfortable.

Therefore, in the present embodiment, the flow rate of the fluid flowing out to the drive unit flow path 9a side is controlled by rotating the valve body 53, and the flow out to the main flow path 9b side by rotating the valve body 23. It is also possible to control the flow rate of the fluid.
That is, the flow rate of the fluid flowing through the main flow path 9b is controlled by the throttle 23a so that the flow rate change caused by the control by the throttle 53b is offset by the throttle 23a and the throttle 53b being linked by the linkage mechanism 24. It has come to be.

FIG. 23 is a schematic diagram for illustrating the flow rate control by the valve bodies 53 and 23. That is, FIG. 23A shows the case where the drive section flow path 9a side is fully opened (when the hydraulic drive device 2 is driven: the first state), and FIG. 23B shows the drive section flow path 9a side fully closed. This is the case of (blocking) (when driving of the hydraulic drive device 2 is stopped). In addition, the arrow in a figure represents the flowing water direction.
As described above, the switching unit 4a and the switching unit 4b are connected by the interlocking mechanism 24. Therefore, the valve body 23 is also rotated by moving the valve body 53 in the rotation direction, and the throttle amount (channel resistance value) on the drive unit channel 9a side and the throttle amount (channel resistance value) on the main channel 9b side. Can be controlled collectively.

  As shown in FIG. 23 (a), when the hydraulic drive device 2 is driven (first state), the drive channel 9a side is fully opened so that the flow rate required for driving can be ensured, and the main flow channel 9b. The diaphragm 23a of the channel on the side is throttled so that the throttle amount A1 is obtained. Although the hydraulic drive device 2 can be driven without being fully opened, it is assumed to be fully opened here for convenience of explanation.

  As described above, the fluid W1 introduced into the hydraulic drive device 2 is discharged from the nozzle hole 3c via the inlets 232 and 234 and the flow path 282. Therefore, the sum of the channel resistances on the side of the main channel 9b that is directly discharged from the nozzle hole 3c through the main channel 9b is larger than the sum of the channel resistances on the side of the drive unit channel 9a. There is a possibility that the flow rate of the fluid W1 flowing toward the partial flow path 9a is insufficient.

  Therefore, in the present embodiment, the flow resistance of this portion is increased by restricting the restrictor 23a on the main flow path 9b side, and the flow rate of the fluid flowing toward the drive section flow path 9a is ensured. In this case, the amount of restriction (the value of the channel resistance) is determined in consideration of the balance between the total channel resistance on the main channel 9b side and the total channel resistance on the drive unit channel 9a side. The total flow resistance on the drive section flow path 9a side means the total flow path resistance from the branch section to the water discharge section 3 through the drive section flow path, and the total flow resistance on the main flow path 9b side. Means the sum total of the channel resistance from the branch part to the water discharge part 3 through the main channel.

That is, in the present embodiment, the flow resistance of the main flow path is controlled so that the flow rate discharged from the water discharger is the same when the water discharger is repeatedly moved and when the water discharger is stopped. I am doing so. For example, when it is desired to repeatedly move the water discharger, the amount of water for driving the hydraulic drive unit 2 is supplied into the hydraulic drive unit and further supplied to the main flow path, so that the water discharge from the water discharger is performed. The flow rate is increased. On the other hand, when it is desired to stop the repetitive movement of the water discharger, the entire amount is supplied to the main flow path without supplying hot water to the hydraulic drive device 2. At this time, the flow rate of water discharged from the water discharger is prevented from decreasing by switching so that the flow resistance of the main flow path becomes smaller than when the water discharger is repeatedly moved.
Therefore, the total flow resistance on the main flow path 9b side and the drive section flow path 9a are set so that the flow rate discharged from the water discharge section is the same when the water discharge section is repeatedly moved and when the water discharge section is stopped. The amount of restriction (channel resistance value) is determined in consideration of the balance with the total channel resistance on the side.

  As shown in FIG. 23 (b), when the drive of the hydraulic drive device 2 is stopped (second state), the drive unit flow path 9a side is fully closed (closed), and the flow path on the main flow path 9b side. The aperture 23a is expanded so that the aperture amount A2 is obtained. Therefore, even if the drive unit flow path 9a side is fully closed (closed), the flow rate of the fluid flowing through the main flow path 9b side is increased, so that the amount of water discharged from the nozzle hole 3c can be ensured. Even if it is not fully closed (closed), the hydraulic drive device 2 can be stopped due to frictional resistance, but for the sake of convenience of description, it is assumed to be fully closed (closed) here.

  In this case, the throttle amount (flow path resistance value) is such that the same amount of water discharged as when the hydraulic drive device 2 is driven (in the case of FIG. 23A) is discharged from the nozzle hole 3c. ing. That is, the sum of the flow rates Va and Vb of each flow path when the hydraulic drive device 2 is driven is the same as the flow rate Vc when the drive of the hydraulic drive device 2 is stopped (discharged from the nozzle hole 3c). The amount of restriction (the value of flow path resistance) is such that the amount of water discharged is the same.

Further, in order to adjust the speed of the hydraulic drive device 2, the throttle 23a of the flow path on the main flow path 9b side is also adjusted when the flow path on the drive section flow path 9a side is throttled (for example, when it is half open). Thus, the amount of water discharged from the nozzle hole 3c is the same. That is, the throttle amount (the value of the channel resistance) on the drive unit channel 9a side so that the amount of water discharged from the nozzle hole 3c is the same regardless of whether or not the hydraulic drive device 2 is driven. ) And the amount of restriction (the value of the flow path resistance) on the main flow path 9b side are collectively controlled.
Further, the flow path resistance in the valve body 53 and the valve body 23 may be changed continuously. This is preferable because the amount of discharged water can be made constant during switching between the state in which the shower water discharger is repeatedly exercised and the state in which it is stopped. Further, the speed of the hydraulic drive device 2 can be easily adjusted.

FIG. 24 is a schematic diagram for illustrating a valve body.
FIG. 24A illustrates the valve body 53 provided in the switching unit 4a. As shown in FIG. 24A, the valve element 53 has a columnar shape, and a throttle 53b that is bent in an L shape in the radial direction and penetrates is provided in the vicinity of one shaft end. Further, a flat portion for attaching the gear 24a is provided in the vicinity of the other shaft end. And in order to hold | maintain the axial direction position of the valve body 53, the groove part 53c by which the holding body which is not shown in figure is slidably provided is provided.

  FIG. 24B illustrates the valve body 23 provided in the switching unit 4b. As shown in FIG. 24 (b), the valve body 23 has a cylindrical shape, and a throttle 23a penetrating the radial direction linearly is provided at an intermediate portion in the axial direction. Further, a flat portion for attaching the gear 24b is provided in the vicinity of the shaft end. And in order to hold | maintain the axial direction position of the valve body 23, the groove part 23c by which the holding body which is not shown in figure is slidably provided is provided.

  When the hydraulic drive device 2 is driven, that is, in the case illustrated in FIG. 23A, on the flow path that connects the inflow port 11a and the outflow port 11c so as to ensure a flow rate necessary for driving. The provided diaphragm 53b is set to the “fully open state”. That is, the flow path resistance is minimized by aligning the axis of the throttle 53b with the axis of the flow path communicating with the throttle 53b. Further, a flow path resistance is given to the main flow path 9b side by a restriction 23a provided on the flow path that connects the inflow port 11d and the outflow port 11b.

  When the drive of the hydraulic drive device 2 is stopped, that is, in the case illustrated in FIG. 23B, the throttle 53b provided on the flow path connecting the inflow port 11a and the outflow port 11c is “fully closed ( (Blocking) state ”. That is, the communication between the inflow port 11a and the outflow port 11c is blocked at the outer peripheral surface of the valve body 53 in the portion where the throttle 53b is provided. In this case, since the throttle 53b is bent in an L shape, the communication between the inlet 11a and the outlet 11c is blocked by the portion of the outer peripheral surface where the throttle 53b is not open.

  Further, the throttle 23a provided on the flow path connecting the inflow port 11d and the outflow port 11b is in the “fully open state”. That is, the axis of the throttle 23a and the axis of the flow path communicating with the throttle 23a are matched. Therefore, even if the throttle 53b is fully closed (closed) and the outflow to the drive unit flow path 9a is stopped, the flow rate of the fluid flowing through the main flow path 9b increases, so the amount of water discharged from the nozzle hole 3c is reduced. Can be secured.

  Even when the aperture 23a is in the “fully open state”, the aperture size is such that a predetermined flow path resistance value (aperture amount) is given. In this case, the flow resistance value (throttle amount) given by setting the throttle 23a to the “fully open state” is the same as the water discharge amount when the hydraulic drive device 2 is driven (in the case of FIG. 23 (a)). The value is such that water is discharged from the nozzle hole 3c.

Further, in order to adjust the speed of the hydraulic drive device 2, the throttle of the flow path on the main flow path 9b side is also adjusted when the flow path on the drive section flow path 9a is throttled (for example, when it is half open). Therefore, the amount of water discharged from the nozzle hole 3c is the same.
That is, the amount of water discharged from the water discharger 3 is the same regardless of the driving state of the hydraulic drive device 2 by controlling the flow rate by the throttle 23a and the throttle 53b being interlocked by the interlocking mechanism 24. Become.

  An operation means (not shown) for operating the switching unit 4a (rotating operation of the valve body 53) can be provided. For example, a handle or the like can be provided on the end surface of the gear 24a, and the gear 24a can be rotated by the handle. As described above, since the drive and stop of the hydraulic drive device can be switched by one operation of the handle, it is easy to use.

Next, the operation of the shower device 50 will be illustrated.
FIG. 25 is a schematic cross-sectional view for illustrating the operation of the shower device 50.
The fluid W1 (hot water) whose temperature has been adjusted by the temperature control valve 8 (not shown) is introduced into the constant flow valve 5 provided in the water inlet of the shower device 50. The fluid W1 introduced into the constant flow valve 5 flows out toward the switching unit 4a. The fluid W1 flowing out from the constant flow valve 5 is introduced into the main body 11 of the switching unit 4a from the inflow port 11a. The fluid W1 introduced into the main body 11 flows out from the outlets 11b and 11c through the two branched channels.
At this time, the switching unit 4a can switch between driving and stopping of the hydraulic drive unit 2 and adjust the speed. Note that the operation of the switching unit 4a (the rotating operation of the valve body 53) can be performed by rotating the gear 24a by an operating means (not shown).

  Further, as described above, the switching unit 4b restricts the main flow path 9b side so that the amount of water discharged from the nozzle hole 3c is the same regardless of whether the hydraulic drive device 2 is driven or not. The amount (flow resistance value) is controlled. At this time, since the switching unit 4a and the switching unit 4b are connected via the interlocking mechanism 24 (the gears 24a and 24b), the throttle amount (channel resistance value) on the drive unit channel 9a side and the main channel 9b. The throttle amount (flow resistance value) on the side is controlled collectively.

In this case, the amount of restriction (the value of the flow path resistance) is controlled by moving the valve bodies 23 and 53 provided with the restriction 23a and the restriction 53b in the rotation direction, thereby allowing the flow passages of the restriction portions (the restriction 23a and the restriction 53b). This is done by changing the cross-sectional area.
The fluid W1 flowing out from the outflow port 11b is introduced into the water discharger 3, and is discharged outward from the nozzle hole 3c provided in the nozzle plate 3b.

The fluid W1 flowing out from the outflow port 11c is introduced into the hydraulic drive device 2 through the drive unit flow path 9a. The fluid W <b> 1 introduced into the hydraulic drive device 2 flows out toward the water discharge unit 3 after driving the hydraulic drive device 2. In addition, about the effect | action of the hydraulic drive device 2, since it is the same as that of what was illustrated in FIG. 8, the description is abbreviate | omitted.
And the fluid W1 which flowed out from the hydraulic drive unit 2 and was introduced into the water discharge part 3 is also discharged toward the outside from the nozzle hole 3c provided in the nozzle plate 3b.

Also in this embodiment, the same effect as that illustrated in FIG. 1 can be obtained. For example, the main body in a state where the hydraulic drive device 2 is driven and water is discharged while the main body 3 is repetitively moved (first state), and in a state where water is discharged from the main body 3 while the hydraulic drive device 2 is stopped (second state). The amount of water discharged from 3 can be made the same. Further, since the water discharge flow rate can be made substantially the same, there is no need to perform troublesome flow rate adjustment when switching the exercise state, and there is no sense of incongruity due to the change in flow rate, and continuity of the showering feeling can be ensured. Further, by keeping the flow rate constant, it is possible to prevent the temperature of the hot water discharged from the water discharger from changing unintentionally without being affected by the hot water supply capability (ignition determination). That is, the repetitive motion of the water discharger can be changed smoothly, and the flow rate and hot water temperature discharged from the water discharger can be kept constant. Therefore, the continuity of the shower feeling can be further maintained during the switching operation. Since the fluid force acting on the core is reduced by reducing the flow rate supplied to the hydraulic drive unit 2, the user can manually move the watering direction of the water discharger 3 while the water discharger 3 is stopped. it can. Further, in the case of a hydraulic drive device in which pressure chambers are provided on both sides of the core, a damper effect is exerted on the core by the hot water in the pressure chamber, so when the water discharger 3 is manually moved, Positioning is easy without any movement, and an appropriate operational feeling can be obtained. Moreover, since the movement of the core is slower than that of the water wheel, the power transmission unit is simplified. Therefore, the torque required to manually move the shower unit is reduced.
In addition, since a configuration in a form suitable for each flow path can be employed, the degree of freedom in design is high, and the control resolution can be increased.

FIG. 26 is a schematic diagram for illustrating the configuration of the shower device according to the fifth embodiment of the invention.
As shown in FIG. 26, the shower device 60 includes a hydraulic drive device 132, a water discharger 133, a valve unit 134 in which a switching unit 4a, a switching unit 4b, and the like are built, a housing 136, a link mechanism 137, A support body 138 and a speed adjustment mechanism 139 are provided. In addition, a water stop valve 7 and a temperature control valve 8 are provided in a pipe that forms a flow path to the shower device 60. And these are connected by piping, and fluids, such as hot water supplied to the water inlet of the temperature control valve 8, can be discharged from the nozzle hole of the water discharger 133 as water discharge W2 (shower water discharge).

  The water discharger 133 includes a rectangular parallelepiped main body 133a having a space inside, and a nozzle plate provided on the front surface of the main body 133a and having a plurality of nozzle holes. A space (not shown) provided in the main body 133a communicates with the nozzle hole.

  A hole having a circular cross section is provided in the axial end surface of the main body 133a, and a support provided in the valve unit 134 is mounted in the hole provided in one axial end surface so that the liquid unit is liquid-tight. A hole provided in the end face is mounted so that the outflow part of the support body 138 having a flow path therein is liquid-tight. In this case, the inside of the support body 138 bears a part of the second drive section flow path that communicates from the drive section 132 to the water discharge section 133.

  The main body 133a is held by the support portion and the support body 138 attached to the hole so as to be freely movable, and the fluid W1 is provided inside the water discharger 133 via the outflow portion of the support body 138. It is possible to flow into the space that does not. Further, the fluid W1 that has flowed into a space (not shown) can be discharged from the nozzle hole as discharged water W2.

  In the hydraulic drive device 132, the shaft of the core is protruded on both sides of the housing, and one of the swing shafts is provided with a flow path (not shown) in the same manner as the water discharge cylinder 280, and the other swing shaft is provided with the other swing shaft. Does not provide a flow path.

Further, the water discharger 133 and the hydraulic drive device 132 are connected via a link mechanism 137. In addition, since the other structure and effect | action of the hydraulic drive apparatus 132 are the same as that of the hydraulic drive apparatus 2 mentioned above, the description is abbreviate | omitted.

Further, the switching unit 4a is provided in the first drive section flow path 9a downstream from the branch section, and the switching unit 4b is provided in the main flow path 9b downstream from the branch section. In addition, the operation mechanism 134a, the first interlock mechanism 134b for transmitting the operation from the operation mechanism 134a to the switching unit 4a, and the second interlock mechanism for transmitting the operation from the operation mechanism 134a to the switching unit 4b. 134c. Therefore, the switching unit 4a and the switching unit 4b are interlocked by operating the operation mechanism 134a. That is, in the present embodiment, the operation mechanism 134a, the first interlocking mechanism 134b, and the second interlocking mechanism 134c are “interlocking mechanisms”.
The valve unit 134 includes a support portion at an end surface thereof, and a flow path formed inside the valve unit 134 communicates with the inside of the water discharger 133 to form a main flow path 9b. In addition, it has the same configuration and operation as the switching unit 4a and the switching unit 4b described above except that the arrangement of the inlet and outlet is different. Therefore, the description is omitted.

In this case, the first interlocking mechanism 134b and the second interlocking mechanism 134c can be mechanical interlocking mechanisms such as gears, links, and wires, and a motor or a solenoid is provided for each of the switching unit 4a and the switching unit 4b. It is also possible to provide an electrical interlocking mechanism that interlocks them with an electrical signal. That is, the interlocking mechanisms 134b and 134c only need to interlock the switching unit 4a and the switching unit 4b.

The housing 136 is provided with a frame to which the hydraulic drive device 132, the valve unit 134, the support 138, the speed adjustment mechanism 139, and the like are attached, and a cover that covers and accommodates these and piping members. For example, the frame is attached to a wall surface such as a bathroom or a shower room, and the shower device 60 is fixed to the wall surface or the like via the frame. The frame and cover are preferably made of a corrosion-resistant material, and can be made of a corrosion-resistant metal such as synthetic resin or stainless steel, for example.

  As described above, the link mechanism 137 is mechanically connected to the shaft of the hydraulic drive device 132 as described above, and the output side is mechanically connected to the main body 133a. Further, a part of the link mechanism 137 may be provided with a one-stage or multi-stage gear train. In this case, the water discharger 133 can be smoothly and repeatedly moved even when the hydraulic power is weak.

  The support 138 is provided with an outflow portion and an inflow portion, and a flow path (not shown) is provided inside the support body 138 so that the opening provided at the end surface of the outflow portion and the opening provided at the end surface of the inflow portion communicate with each other. Is provided. Further, as described above, the main body 133a is held by the outflow portion so as to be capable of repetitive movement.

  The speed adjustment mechanism 139 is provided in the drive unit flow path 9a and adjusts the speed of the hydraulic drive device 132 by adjusting the flow rate of the fluid supplied to the hydraulic drive device 132. If the speed adjustment mechanism 139 is provided, even if there is a variation in speed due to a manufacturing error or the like, a desired speed can be obtained by adjustment. As the speed adjustment mechanism 139, for example, a speed adjustment valve provided with a throttle valve or the like can be used. However, the present invention is not limited to this, and can be changed as appropriate. Further, the speed adjustment mechanism 139 is used for fine adjustment performed at the time of maintenance or shipment, and may not be normally used by the user of the shower device 60.

In addition, the constant flow valve 5 illustrated in FIG. 1 can be provided as appropriate. The speed adjustment mechanism 139 and the constant flow valve 5 are not necessarily required and can be omitted.
The operation of the shower device 60 is the same as that of the shower device 50 described above, and the description thereof is omitted.

  Also in this embodiment, the same effect as that illustrated in FIG. 1 can be obtained. For example, the main body in a state where the hydraulic drive device 132 is driven and water is discharged while the main body 133 is repetitively moved (first state) and in a state where water is discharged from the main body 133 while the hydraulic drive device 132 is stopped (second state). The amount of water discharged from 133 can be made the same. Further, since the water discharge flow rate can be made substantially the same, there is no need to perform troublesome flow rate adjustment when switching the exercise state, and there is no sense of incongruity due to the change in flow rate, and continuity of the showering feeling can be ensured. Further, by keeping the flow rate constant, it is possible to prevent the temperature of the hot water discharged from the water discharger from changing unintentionally without being affected by the hot water supply capability (ignition determination). That is, the repetitive motion of the water discharger can be changed smoothly, and the flow rate and hot water temperature discharged from the water discharger can be kept constant. Therefore, the continuity of the shower feeling can be further maintained during the switching operation. Since the fluid force acting on the core is reduced by reducing the flow rate supplied to the hydraulic drive device 132, the user can manually move the watering direction of the water discharger 133 while the water discharger 133 is stopped. it can. Further, in the case of a hydraulic drive device in which pressure chambers are provided on both sides of the core, a damper effect is exerted on the core by the hot water in the pressure chamber, so when the water discharger 133 is moved manually, Positioning is easy without any movement, and an appropriate operational feeling can be obtained. Moreover, since the movement of the core is slower than that of the water wheel, the power transmission unit is simplified. Therefore, the torque required to manually move the shower unit is reduced. In addition, since a configuration in a form suitable for each flow path can be employed, the degree of freedom in design is high, and the control resolution can be increased.

FIG. 27 is a schematic diagram for illustrating flow control by a valve body according to another embodiment.
27A shows the case where the drive section flow path 9a side is fully opened (when the water discharge section performs repetitive motion: the first state), and FIG. 27B shows the drive section flow path 9a side fully closed. (Occlusion) (when repetitive movement of the water discharge part is stopped). In addition, the arrow in a figure represents the flowing water direction.
The switching unit 4d is provided with a valve body 13, and the switching unit 4b is provided with a valve body 23.
As in the case described with reference to FIG. 23, the switching unit 4d and the switching unit 4b are connected by the interlocking mechanism 24. Therefore, the valve body 23 is also rotated by moving the valve body 13 in the rotation direction, and the throttle amount (channel resistance value) on the drive unit channel 9a side and the throttle amount (channel resistance value) on the main channel 9b side. Can be controlled collectively.
However, the valve body 13 is provided across the drive part flow path 9a and the main flow path 9b, and distributes the flow rate flowing through the drive part flow path 9a and the flow rate flowing through the main flow path 9b. Further, the valve body 13 is provided with a throttle 13a so that the throttle amounts A1a and A2a can be switched. As a result, the flow path resistance on the main flow path 9b side is adjusted by the switching unit 4d and the switching unit 4b, and the adjustment width is increased and the degree of freedom in design is increased.
Moreover, the switching unit 4b is provided in the main flow path downstream of the switching unit 4d. Note that the switching unit 4d may be provided at a branch portion of the drive section flow path 9a and the main flow path 9b.
When the switching unit 4d is provided at the branch portion, the valve body 73 can be used instead of the valve body 13.

  FIG. 28 is a schematic view for illustrating flow control by a valve body according to another embodiment. FIG. 28A shows the case where the drive section flow path 9a side is fully opened (when the hydraulic drive unit 2 is driven), and FIG. 28B shows the drive section flow path 9a side fully closed (closed). This is the case (when the drive of the hydraulic drive device 2 is stopped). Moreover, the arrow in a figure represents the flowing water direction.

The switching unit 4e is provided with a valve body 63, and the switching unit 4d is provided with a valve body 13.
As in the case described with reference to FIG. 23, the switching unit 4e and the switching unit 4d are connected by the interlocking mechanism 24. Therefore, the valve body 63 is also rotated by moving the valve body 13 in the rotation direction, and the throttle amount (channel resistance value) on the drive section flow path 9a side and the main flow path 9b side by the throttle 63d provided on the valve body 63. The amount of restriction (the value of flow path resistance) can be controlled collectively.
However, the switching unit 4d and the valve body 13 are provided across the drive unit flow path 9a and the main flow path 9b, and distribute the flow rate flowing through the drive unit flow path 9a and the flow rate flowing through the main flow path 9b. The valve body 13 is provided with a throttle 13a. As a result, the flow path resistance on the main flow path 9b side is adjusted by the switching unit 4e and the switching unit 4d, and the adjustment width increases and the degree of freedom in design increases.
Moreover, the switching unit 4d is provided in the main flow path on the downstream side of the branch portion. Note that the switching unit 4d may be provided at a branch portion of the drive section flow path 9a and the main flow path 9b. When the switching unit 4d is provided at the branch portion, the valve body 73 can be used instead of the valve body 13.
Moreover, also in the valve body concerning other embodiment, the effect similar to what was illustrated in FIG. 1 can be enjoyed. For example, the main body in a state where the hydraulic drive device 132 is driven and water is discharged while the main body 133 is repetitively moved (first state) and in a state where water is discharged from the main body 133 while the hydraulic drive device 132 is stopped (second state). The amount of water discharged from 133 can be made the same. Further, since the water discharge flow rate can be made substantially the same, there is no need to perform troublesome flow rate adjustment when switching the exercise state, and there is no sense of incongruity due to the change in flow rate, and continuity of the showering feeling can be ensured. Further, by keeping the flow rate constant, it is possible to prevent the temperature of the hot water discharged from the water discharger from changing unintentionally without being affected by the hot water supply capability (ignition determination). That is, the repetitive motion of the water discharger can be changed smoothly, and the flow rate and hot water temperature discharged from the water discharger can be kept constant. Therefore, the continuity of the shower feeling can be further maintained during the switching operation. Since the fluid force acting on the core is reduced by reducing the flow rate supplied to the hydraulic drive device 132, the user can manually move the watering direction of the water discharger 133 while the water discharger 133 is stopped. it can. Further, in the case of a hydraulic drive device in which pressure chambers are provided on both sides of the core, a damper effect is exerted on the core by the hot water in the pressure chamber, so when the water discharger 133 is moved manually, Positioning is easy without any movement, and an appropriate operational feeling can be obtained. Moreover, since the movement of the core is slower than that of the water wheel, the power transmission unit is simplified. Therefore, the torque required to manually move the shower unit is reduced. Further, since the flow rate flowing through the flow path to be controlled is controlled by the cooperation of the two flow rate control units, the resolution of the control can be increased.

According to the shower device of the present invention, the water discharge part can be automatically and repeatedly moved to change the water discharge position and the water discharge direction, and the user can take a shower of a wide range of shower water discharged in a variety of ways. It can also be fixed and concentrated. At this time, by providing the valve body described above, the flow resistance of the main flow path and the drive section flow path is collectively controlled, and when the water discharge section is repeatedly moved and stopped, water discharge from the water discharge section It is possible to control the flow rate to be the same. Therefore, the amount of water discharged can be made the same even when switching between moving and stopping, and the user can take a shower without feeling uncomfortable, uncomfortable, lack of flow, or the like. Therefore, the continuity of the shower feeling can be ensured.
Moreover, since it can switch by operating one valve body, it is excellent in operativity.
In addition, since the water discharge part that discharges water while moving and the water discharge part that discharges water while stopping are common, the continuity of the showering feeling when switching the movement state of the water discharge part is ensured, and the piping system and appearance are simplified. Can be
Moreover, since the water discharge flow rate does not change, the user does not need to adjust the flow rate each time.
In addition, a drive unit channel and a main channel are provided as water channels to the water discharge unit, and hot water is supplied to the main channel even when the hydraulic drive device is driven. The water discharge flow rate can be increased. Thereby, it can respond also to a low water pressure area and can provide a shower apparatus to more people.
