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.
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.

The hydraulic drive device 2 repeatedly moves the main body 3a of the water discharger 3 in the direction of arrow R when a predetermined amount of fluid is supplied. 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 the line BB in FIG.

As shown in FIG. 5 to FIG. 7, the hydraulic drive device 2 has a configuration in which a water discharge cylinder 280 protrudes from one side 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 inlets 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, resulting in a pressure difference. 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 unit 2 is connected to the water discharger 3 and can perform repetitive motion of the water discharger 3 when a predetermined amount or more of fluid flows in (first state).

Also, 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.

If such a speed adjustment mechanism is provided, even if the movement speed varies due to a manufacturing error or the like, the desired movement 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.

It should be noted that the hydraulic drive device of the present invention is not limited to that illustrated in FIGS. 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 housing 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 that covers and accommodates these and piping members. 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 a 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 exemplified as a flow rate control unit passes through the radial direction linearly, and the throttle 13b passes through the radial direction bent in an L-shape (FIG. 12, (See FIG. 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.

In addition, although restrictor 13a, 13b 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 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.

At this time, in the present 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. Be able to.
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 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 at the maximum speed), and FIG. 10B shows the drive section flow path 9a side fully closed (closed). ) (When the drive of the hydraulic drive unit 2 is stopped), FIG. 10C shows the case where the drive unit passage 9a side is narrowed (when the hydraulic drive unit 2 is driven at a low speed). In addition, the arrow in a figure represents the flowing water direction. *

As shown in FIGS. 10A, 10B, and 10C, the switching unit 4 incorporates the valve body 13 described above, and by moving the valve body 13 in the rotational direction, the drive unit flow path 9a. The amount of restriction on the side (channel resistance value) and the amount of restriction on the main channel 9b side (channel resistance value) can be controlled collectively. By comprising in this way, the connection location of piping is few and the compact structure is implement | achieved.

As shown in FIG. 10 (a), when the hydraulic drive device 2 is driven at the maximum speed (first state), the throttle on the drive unit flow path 9a side is secured so as to ensure the maximum flow rate necessary for driving. 13b is fully opened, and the throttle 13a on the main flow path 9b side is fully closed (closed). If it does in this way, all the fluids introduced into shower device 1 will flow to the drive part channel 9a side, and the speed of hydraulic drive device 2 can be made the fastest.

As shown in FIG. 10 (b), when the drive of the hydraulic drive unit 2 is stopped (second state), the throttle 13b on the drive unit flow path 9a side is fully closed (closed). And in order to make water discharge from the water discharge part 3 in the state which stopped the drive of the hydraulic drive unit 2, the aperture 13a by the side of the main flow path 9b is opened.

Here, the fluid W1 introduced into the hydraulic drive unit 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 drive channel 9a side is larger than the sum of the channel resistances on the main channel 9b side that is directly discharged from the nozzle hole 3c through the main channel 9b.

In such a case, if the throttle amount on the main channel 9b side shown in FIG. 10B is the same as the throttle amount on the drive channel 9a side shown in FIG. As a result, the amount of water discharged from the water discharger 3 is increased.

In the present embodiment, when the throttle 13a on the main channel 9b side is fully opened, the throttle amount is set to a predetermined value A1, thereby suppressing the water discharge amount of the fluid discharged from the water discharge unit 3. ing. In this case, the throttle amount A1 is determined in consideration of the balance between the total flow resistance on the main flow path 9b side and the total flow resistance on the drive section flow path 9a. That is, the throttle amount A1 is set so that the total channel resistance value on the main channel 9b side and the total channel resistance value on the drive unit channel 9a side are the same. 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.

In this way, the flow rate Va when the hydraulic drive device 2 is driven at the maximum speed is the same as the flow rate Vb when the drive of the hydraulic drive device 2 is stopped (the amount of water discharged from the water discharge unit 3). Can be the same).

As shown in FIG. 10C, when the hydraulic drive device 2 is driven at a slow speed (when the speed of the hydraulic drive device 2 is adjusted) (third state), the throttle on the drive unit flow path 9a side Squeeze 13b. And the throttle 13a of the flow path by the side of the main flow path 9b is restrict | squeezed so that the quantity of the discharged water discharged from the water discharge part 3 may become the same. For example, in the case shown in FIG. 10C, the throttle 13b on the drive section flow path 9a side is set to the throttle amount A2, and the throttle 13a on the main flow path 9b side is set to the throttle amount A3. In this case, the amount of water discharged from the water discharger 3 is the sum (Vc1 + Vc2) of the flow rates of the fluid flowing through the respective flow paths, which is the same as the flow rate Va and the flow rate Vb described above.

As described above, regardless of whether or not the hydraulic drive device 2 is driven and the speed, the throttle amount on the drive unit flow path 9a side (so that the amount of water discharged from the water discharge unit 3 is constant) The flow path resistance value) and the amount of restriction on the main flow path 9b side (flow path resistance value) are controlled collectively.

In addition, in this specification, the amount of water discharged from the water discharger 3 is constant and the same includes the case where there is a difference in flow rate that does not cause the user to 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 small 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.

In the example illustrated in FIGS. 10A and 10B, the valve body 13 is provided on the downstream side of the branch portion. However, a so-called rotary type valve body (disc-shaped valve body) or cylindrical shape is provided. A valve 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, a throttle 73a illustrated as a first flow rate control unit and a throttle 73b illustrated as a second flow rate control unit are opened.
Further, by rotating the valve body 73, the flow passage cross-sectional area is variable in the portion where the throttles 73a and 73b are provided. Therefore, the throttle 73b controls the flow rate of the fluid flowing through the drive unit flow path 9a by changing the flow path resistance, and the throttle 73a controls the flow rate of the fluid flowing through the main flow path 9b by changing the flow path resistance. Can be done.
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 communication between the inside of the valve body 73 and the outlet 11b is blocked.
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 outflow port 11b are communicated with each other through a throttle 73a 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 73a and the diaphragm 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 the 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.

FIG. 12 is a schematic diagram for illustrating the state of the valve body when the hydraulic drive device 2 is driven at the maximum speed (when the drive unit flow path 9a side is fully opened).
FIG. 13 is a schematic diagram for illustrating the state of the valve body when driving of the hydraulic drive device 2 is stopped (when the drive unit flow path 9a side is fully closed (closed)). FIG. 12 and FIG. 13 are diagrams showing the cross-sectional portion taken along the line CC in FIG. 9 in each case.

As shown in FIG. 12A, when the hydraulic drive device 2 is driven at the maximum speed, the flow path connecting the inflow port 11a and the outflow port 11c is secured so that the flow rate necessary for driving can be ensured to the maximum. The diaphragm 13b provided in is set in the “fully open state”. 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. Further, the opening 15 on the main flow path 9b side is blocked by the outer peripheral surface 13c of the valve body 13 in the portion where the throttle 13a is provided, and the communication between the inflow port 11a and the outflow port 11b is blocked. . FIG. 12B is a schematic perspective view for illustrating the state of the valve body 13 at this time.

As shown in FIG. 13 (a), when stopping the driving of the hydraulic drive device 2, the throttle 13b provided on the flow path that connects the inflow port 11a and the outflow port 11c is in a “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 fluid flows through the main flow path 9b side, so that the amount of water discharged from the water discharge unit 3 is ensured. Can do.

In this case, as described above, even when the aperture 13a is in the “fully open state”, the aperture size is such that a predetermined aperture amount A1 (channel resistance value) is provided. The throttle amount A1 (flow path resistance value) given by setting the throttle 13a to the “fully open state” is the same as that when the hydraulic drive device 2 is driven at the maximum speed (in the case of FIG. 12). The value is such that it is discharged from the section 3. FIG. 13B is a schematic perspective view for illustrating the state of the valve body 13 at this time.

Further, when the hydraulic drive device 2 is driven at a low speed (when the speed of the hydraulic drive device 2 is adjusted), that is, when illustrated in FIG. 10 (c), those illustrated in FIGS. 12 and 13 It becomes a state between. Even in this case, since the throttle amount A2 on the drive channel 9a side and the throttle amount A3 on the main channel 9b side are set to predetermined values, the amount of water discharged from the water discharger 3 is the same.
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.
In addition, the switching unit 4 can also be arrange | positioned in a 2nd drive part flow path. However, if the switching unit 4 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 apparatus 2 when the repetitive motion of the water discharge section 3 is stopped is reduced. be able to.

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.

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.

Further, as described above, the amount of restriction on the drive unit flow path 9a side (the amount of water discharged from the water discharge unit 3 is constant regardless of whether the hydraulic drive device 2 is driven or 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 outlet 11b is introduced into the water discharger 3 and 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 the repetitive motion state and the stop state of the water discharger by operating the handle 10. 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.

In addition, since the fluid force is reduced, the user can manually move the water spraying direction of the water discharger 3 while 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.
Furthermore, 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).
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).

As shown in FIGS. 16 and 17, the water discharger 33 includes a rectangular parallelepiped main body 33a having a space inside, and a nozzle plate 33b provided on the front surface of the main body 33a and having a plurality of nozzle holes 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. At this time, a flow path is also formed inside the support portion 31, and serves as a part of the main flow path 9b.

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, and a flow path formed therein communicates with the inside of the water discharge portion 33.
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 9a, 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.

Also in this embodiment, the same effects as those illustrated in FIG. 1 can be enjoyed. 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 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.

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 diagram for illustrating the flow rate control. 19A shows the case where the drive section flow path 9a side is fully opened (when the hydraulic drive device 32 is driven), and FIG. 19B shows the drive section flow path 9a side fully closed (closed). This is the case (when the drive of the hydraulic drive device 32 is stopped). In addition, the arrow in a figure represents the flowing water direction.
As shown in FIG. 18, the shower device 40 includes a hydraulic drive device 32, a water discharger 33, a switching unit 4, a housing 36, a link mechanism 37, a support 38, a resistor 45, and a constant flow rate. And a valve 5. 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 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 33 as water discharge W2 (shower water discharge).

The switching unit 4 includes a valve body 43 (see FIG. 19) therein, and moves the valve body 43 in the rotation direction, thereby opening and closing the flow path on the drive section flow path 9a side and the flow path on the main flow path 9b side. The opening and closing can be controlled collectively. In this case, if the flow channel on the drive unit flow channel 9a side is opened, the flow channel on the main flow channel 9b side is closed (the state of FIG. 19A), and if the flow channel on the drive unit flow channel 9a side is closed, the main flow is obtained. The flow path on the side of the path 9b is opened (state shown in FIG. 19B). In other words, alternative flow path switching (switching between driving and stopping of the hydraulic drive device 32) can be performed.

Here, as described above, water is discharged through the drive unit flow path 9a and the hydraulic drive device 32 rather than the sum of the flow path resistances on the main flow path 9b side discharged directly from the water discharge unit 33 through the main flow path 9b. The sum of the channel resistances on the drive unit channel 9a side discharged from the section 33 is larger.

In such a case, if the switching unit 4 is simply used to open and close the flow path, the amount of water discharged from the water discharger 33 in the state shown in FIG. 19A and the state shown in FIG. And momentum will change. That is, in the state of FIG. 19B (when the drive of the hydraulic drive device 32 is stopped), the amount and momentum of the water discharged from the water discharger 33 increases.
In the present embodiment, a resistor 45 having a restriction 45a is provided in the main channel 9b, and a predetermined channel resistance value A4 is given by the resistor 45 so as to suppress the flow rate of the fluid flowing through the main channel 9b. ing. In this case, the channel resistance value A4 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. That is, the channel resistance value A4 is set such that the total channel resistance value on the main channel 9b side and the total channel resistance value on the drive unit channel 9a side are the same.

By doing so, in the case of driving the hydraulic drive device 32 (in the case of FIG. 19A) and in the case of stopping the drive of the hydraulic drive device 32 (in the case of FIG. 19B), the water discharger 33. Can discharge the same water discharge amount. That is, the flow rate Vd when the hydraulic drive device 32 is driven is the same as the flow rate Ve when the drive of the hydraulic drive device 32 is stopped.

The resistor 45 is provided in the main flow path 9b on the downstream side of the switching unit 4, and gives a predetermined flow path resistance value A4. As the throttle 45a, for example, a fixed throttle having a predetermined channel cross-sectional area (for example, when a member having a predetermined channel cross-sectional area is provided in a pipe or a pipe diameter is throttled), a channel cross-sectional area is used. Variable flow restrictors (for example, various valves such as a needle valve) that can adjust the flow path resistance, and adjusting the pipe diameter, pipe length, etc. to adjust the flow path resistance to a predetermined value be able to.

In this case, if a variable aperture such as a valve is used, manufacturing errors and the like can be absorbed by adjustment. Moreover, the adjustment according to the installation environment of the shower apparatus 40 is also attained. Further, if the flow path resistance is given by a fixed throttle, pipe diameter, pipe length, etc., the structure can be simplified. In particular, if a predetermined flow path resistance value is given depending on the pipe diameter, pipe length, etc., it is possible to reduce the manufacturing cost because no additional parts are required. When the flow path resistance value is given by the pipe diameter or the pipe length, the main flow path 9b itself becomes the resistor 45. However, the present invention is not limited to these, and a material that can provide a predetermined flow path resistance can be appropriately selected.
In addition, about the effect | action of the shower apparatus 40, since it is the same as that of the shower apparatus 1 mentioned above, the description is abbreviate | omitted.

As described above, according to the present embodiment, regardless of whether or not the hydraulic drive device 32 is driven (regardless of whether or not the water discharger 33 performs repetitive motion), the water discharger 33 discharges. The amount of discharged water can be made the same.

Also in this embodiment, the same effects as those illustrated in FIG. 1 can be enjoyed. 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 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.

FIG. 20 is a schematic view for illustrating the configuration of the shower device according to the fourth embodiment of the invention.
FIG. 21 is a schematic diagram for illustrating the flow rate control. 21A shows a case where the drive unit flow channel 9a side is fully opened (when the hydraulic drive device 32 is driven), and FIG. 21B shows a case where the drive unit flow channel 9a side is fully closed (closed). This is the case (when the drive of the hydraulic drive device 32 is stopped). In addition, the arrow in a figure represents the flowing water direction.

As shown in FIG. 20, the shower device 50 includes a hydraulic drive device 32, a water discharger 33, a switching unit 4, a variable resistor 55, an interlock mechanism 56, a housing 36, a link mechanism 37, and a support. The body 38 and the constant flow valve 5 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 50. 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 33 as water discharge W2 (shower water discharge).

The switching unit 4 and the variable resistor 55 are connected by an interlocking mechanism 56. The switching unit 4 and the variable resistor 55 can control the flow rate as well as switching between water flow and water stop. The switching unit 4 is provided at the branch portion, and the variable resistor 55 is provided upstream from the branch portion. Then, by rotating the handle (not shown), the interlocking mechanism 56 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.

Also in the present embodiment, the switching unit 4 described above is provided, and if the flow path on the drive section flow path 9a is opened, the flow path on the main flow path 9b side is closed (the state of FIG. 21A), and the drive section If the channel on the side of the channel 9a is closed, the channel on the side of the main channel 9b is opened (state shown in FIG. 21B).

Then, a variable resistor 55 is provided in the water supply channel 16 on the upstream side of the switching unit 4, and the switching unit 4 and the variable resistor 55 are interlocked by the interlocking mechanism 56, whereby the channel on the main channel 9b side is opened. In this case, a predetermined flow path resistance value A5 is given by the variable resistor 55. In addition, the variable resistor 55 can be provided in the main flow path 9b on the downstream side of the switching unit 4.

In this case, the channel resistance value A5 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. That is, the channel resistance value A5 is set so that the total channel resistance value on the main channel 9b side and the total channel resistance value on the drive unit channel 9a side are the same.

By doing so, in the case of driving the hydraulic drive device 32 (in the case of FIG. 21A) and in the case of stopping the drive of the hydraulic drive device 32 (in the case of FIG. 21B), the water discharger 33. Can discharge the same water discharge amount. That is, the flow rate Vf when driving the hydraulic drive device 32 and the flow rate Vg when stopping driving the hydraulic drive device 32 are the same.

The type of the variable resistor 55 is not particularly limited as long as it can provide a predetermined flow path resistance value A5. For example, a valve body having a hole penetrating the radial direction of the column like the switching unit 4 may be rotated to give a predetermined flow path resistance value A5.

The type of the interlocking mechanism 56 is not particularly limited as long as the switching unit 4 and the variable resistor 55 are interlocked so that the channel can be switched and the channel resistance value can be given. . For example, a mechanical interlocking mechanism such as a gear, a link, or a wire can be used, or an electric motor that connects a motor or a solenoid to each of the switching unit 4 and the variable resistor 55 and interlocks them with an electrical signal. It can also be set as a general interlock mechanism. Further, the variable resistor 55 may operate in conjunction with the operation of the switching unit 4, or the switching unit 4 may operate in conjunction with the operation of the variable resistor 55. The flow path resistance value A5 can also be adjusted by selecting the number of gear teeth, the link lever ratio, the rotation angle of the motor, and the like.
In addition, about the effect | action of the shower apparatus 50, since it is the same as that of the shower apparatus 1 mentioned above, the description is abbreviate | omitted.

According to the present embodiment, the switching unit 4 and the variable resistor 55 are interlocked by the interlocking mechanism 56, so that when the channel on the main channel 9b side is opened, the variable resistor 55 causes a predetermined flow. A road resistance value A5 is given. Therefore, the amount of water discharged from the water discharger 33 can be made the same regardless of whether the hydraulic drive device 32 is driven.

In addition, although the case where the fluid flowing out from the hydraulic drive unit is directly supplied to the water discharge unit is illustrated, the fluid flowing 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 effects as those illustrated in FIG. 1 can be enjoyed. 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 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, 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, 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. 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.

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. 23 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. 22 and 23, the shower device 60 includes a hydraulic drive device 62, a water discharge unit 33, a switching unit 4 in which the valve body 13 is built, a housing 36, a link mechanism 37, and a support body. 68. 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 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 65b, 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 68a of the support body 68 is mounted in a hole 33f provided on the other axial end face so as to be liquid-tight. The hole 33f on the side where the support portion 68a is mounted need not be connected to a space (not shown) inside the main body 33a. In this case, a hole can be provided at the bottom of the hole 33f on the side where the support 68a is mounted. 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 68a so as to be liquid-tight.

Further, the main body 33a is held by the outflow portion 65b and the support portion 68a 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 65b. 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.

The core shaft 62b protrudes from one end face of the hydraulic drive device 62. The shaft 62b is provided with a flow path (not shown) inside, similar to the water discharge cylinder 280 described above. The shaft 62b is mechanically connected to the link mechanism 37. Therefore, the driving force of the hydraulic drive device 62 is transmitted to the link mechanism 37. Further, the water discharger 33 and the hydraulic drive device 62 are connected via a link mechanism 37. In addition, since the other structure and effect | action of the hydraulic drive unit 62 are the same as that of the hydraulic drive unit 2 mentioned above, the description is abbreviate | omitted.

A junction 65 is provided on the end surface of the switching unit 4.
A flow path is formed inside the merging portion 65. The flow path formed inside the merging portion 65 is connected to the flow path formed in the switching unit 4. In the present embodiment, the flow path formed inside the merging portion 65 forms the main flow path 9b.
The junction 65 is provided with an inflow portion 65a and an outflow portion 65b. The end surfaces in the axial direction of the inflow portion 65a and the outflow portion 65b are opened, and each is connected to a flow path formed inside the confluence portion 65.
Moreover, the inflow part 65a and the axis | shaft 62b are connected by piping which is not shown in figure. In the present embodiment, the flow path formed by connecting the inflow portion 65a and the shaft 62b becomes the drive portion flow path 19 (second drive portion flow path). For this reason, the main flow path 9 b and the drive section flow path 19 can be merged on the upstream side of the water discharge section 33 by the merge section 65.
If the junction 65 is provided as in the present embodiment, the number of connecting portions 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 62 can be reduced, and the hydraulic drive device 62 can be downsized and the shower device 60 can be downsized.

The housing 36 is provided with a frame 36a to which the hydraulic drive device 62, the switching unit 4, the support 68, the merging portion 65, 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 60 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.

The input side of the link mechanism 37 is mechanically coupled to the shaft 62b as described above. 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 60 is the same as that of the shower device 1 described above, and the description thereof is omitted.

Also in this embodiment, the same effects as those illustrated in FIG. 1 can be enjoyed. For example, the main body in a state where the hydraulic drive device 62 is driven to discharge water while the main body 33 is repetitively moved (first state) and a state where the hydraulic drive device 62 is stopped and water is discharged from the main body 33 (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 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 62, the user can manually move the watering 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.

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, the flow resistance of the main flow path and the drive section flow path is collectively controlled so that the flow rate discharged from the water discharge section is the same when the water discharge section is repeatedly moved and stopped. Can be controlled. 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.
Further, since the valve body and the flow rate control unit are interlocked, switching can be performed with one operation, so that the operability is excellent.
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.
