  By the way, from the viewpoint of usability of the water discharger, there is a request for countermeasures against water splashing, but there is also a request for increasing the flow rate of the water discharge flow. Although the conventional structure described above can meet the demand for countermeasures against water splashing, the amount of water supplied to the water discharge device is limited to a set flow rate or less, and is not suitable for increasing the flow rate of the water discharge flow. Therefore, there is room for further improvement from the viewpoint of satisfying the two requirements described above.

  This invention is made in view of such a subject, The objective is to provide the water discharging component which responds also to the request | requirement to the large flow volume of a discharged water flow, responding to the request | requirement for a water splash countermeasure.

  The 1st mode of the present invention for solving the above-mentioned subject is a water discharge part. The water discharge component of the first aspect is a first water channel for guiding water sent from the upstream water channel to the plurality of shower holes, and a second for guiding water sent from the upstream water channel to the water discharge holes for straight water discharge. A first communication state in which the first water channel communicates with the upstream water channel, and a second communication state in which the second water channel communicates with the upstream water channel. And a valve device provided on the first water channel and capable of controlling the flow rate of water flowing out through the inside thereof.

  According to the water discharge component of the first aspect, when switching to the first communication state, even when a large flow of water is sent from the upstream water channel, the discharge discharged from the plurality of shower holes by way of the valve device The flow velocity of the water flow can be suppressed and water splashing at the landing point can be prevented. Moreover, when switched to the second communication state, a large flow rate of water discharge can be discharged from the water discharge hole through the second water passage not via the valve device. Therefore, while responding to the demand for water splash countermeasures, it is possible to meet the demand for a large discharge water flow.

The water discharging apparatus 12 of this embodiment is a faucet apparatus used for a kitchen. The water discharging device 12 is fixed to a device fixing portion 14 a provided in a water receiving tank 14 such as a sink.

  The water discharge device 12 includes a water discharge component 10 for discharging water and a device main body 16 to which the water discharge component 10 is attached. The apparatus main body 16 includes a tubular body 16b on which the water discharge component 10 is attached to the distal end portion 16a, a trunk portion 16c provided at the root portion of the tubular body 16b, and a lever 16d attached to the distal end portion of the trunk portion 16c. Have. The tubular body 16b constitutes a water discharge pipe in which a water supply channel (not shown in FIG. 1) for supplying water to the water discharge component 10 is provided. The distal end portion of the tubular body 16b constitutes a water discharge head 16e that is detachably held with respect to the root portion of the tubular body 16b. The lever 16d is a so-called single lever capable of adjusting the temperature and flow rate of water discharged from the water discharge component 10 through operation of the valve unit 16f disposed in the body portion 16c.

  FIG. 2 is a side sectional view of a part of the water discharge device 12. The distal end portion of the tubular body 16b has an internal member 16h provided with a part of the water supply channel 16g described above, and a cover member 16i that covers the internal member 16h. Inside the distal end portion 16a of the tubular body 16b, an opening 16j through which the water discharge component 10 is inserted and a mounting hole 16k in which the water discharge component 10 is mounted are provided. The opening 16j is formed in the cover member 16i. The mounting hole 16k is formed at the downstream end of the water supply path 16g of the internal member 16h.

  FIG. 3 is a side sectional view showing the water discharge component 10. The water discharge component 10 includes a first water channel forming member 18, a second water channel forming member 20, an operation member 22, and a valve device 24. One of the main features of the water discharge component 10 is the valve device 24, but the peripheral structure will be described first.

  The first water channel forming member 18 includes a water sprinkling part 26, an inner cylinder part 28, an outer cylinder part 30, a shower water discharge water channel 32 (first water channel), and a straight water discharge water channel 34 (second water channel).

  The water sprinkling part 26 is plate-shaped, and a plurality of shower holes 26a penetrates the front and back. Each of the plurality of shower holes 26a is configured to discharge a single linear water flow. The plurality of shower holes 26 a are formed in the annular region 26 c on the outer peripheral side of the central region 26 b of the sprinkling part 26, and are not formed in the central region 26 b of the sprinkling part 26.

  The inner cylinder part 28 protrudes from the outer peripheral part of the water sprinkling part 26 toward the back side. The outer cylinder part 30 is disposed on the outer peripheral side of the water spray part 26 and the inner cylinder part 28. The outer cylinder part 30 is connected to the inner cylinder part 28 via a plate-like rib part 36 disposed between the outer cylinder part 30 and the inner cylinder part 28.

  A water discharge hole 38 for straight water discharge is formed between the outer cylinder part 30 and the water spray part 26. Here, “straight water discharge” means that water sent from the straight water discharge channel 34 is not discharged as a plurality of water streams in a shower form, but is discharged straight (as it is) as a single water stream. The water discharge hole 38 is provided in an annular shape so as to surround the plurality of shower holes 26 a of the water spray part 26. A guide surface 38 a for directing the discharge direction of the water flow discharged from the water discharge hole 38 radially inward is formed on the inner wall surface forming the water discharge hole 38 of the outer cylinder part 30. The water flow discharged from the water discharge hole 38 is guided by the guide surface 38a, thereby forming a single water flow that gradually narrows.

  The shower water discharge channel 32 is for guiding water sent from a water flow channel 42 (described later) of the second water channel forming member 20 to the plurality of shower holes 26a. Here, “shower water discharge” refers to discharging water sent from the shower water discharge channel 32 in a shower form as a plurality of water streams. The shower water discharge channel 32 is formed on the inner peripheral side of the inner cylinder portion 28 and on the back side of the water sprinkling portion 26.

  The straight water discharge channel 34 is for guiding the water sent from the water channel 42 of the second water channel forming member 20 to the water discharge hole 38. The straight water discharge channel 34 is formed between the outer cylinder part 30 and the inner cylinder part 28.

  The first water channel forming member 18 has a discharge surface 40 for discharging water flow. The discharge surface 40 is formed on the distal end surface of the outer cylinder part 30 and an opening 40a for allowing a water flow to pass therethrough is formed. The water flow that has passed through the plurality of shower holes 26 a and the water discharge holes 38 is discharged from the discharge surface 40 to the outside.

  The second water channel forming member 20 is disposed on the back side of the first water channel forming member 18. The second water channel forming member 20 has a tubular shape as a whole, and a water flow channel 42 serving as an upstream water channel for guiding water to the shower water discharging channel 32 and the straight water discharging channel 34 is formed inside thereof. The water channel 42 of the second water channel forming member 20 is supplied with water sent from the water supply channel 16 g of the apparatus main body 16.

  The second channel forming member 20 has its upper portion 20a mounted in the mounting hole 16k of the apparatus main body 16 by a screw structure or the like (see also FIG. 2). The second water channel forming member 20 is slidably fitted to the inner side of the outer cylindrical portion 30 of the first water channel forming member 18 at its lower portion 20b.

  The operation member 22 is for performing an operation of switching between a first communication state and a second communication state, which will be described later. The operation member 22 has a cylindrical shape as a whole, and is disposed on the outer peripheral side of the first water channel forming member 18 and the second water channel forming member 20. The operation member 22 is provided with a knob portion 22 a that protrudes outward in the radial direction of the operation member 22.

  The operation member 22 is provided with an inner step portion 22b protruding inward at an upper end portion thereof. An outer step portion 20 c protruding outward is provided on the outer peripheral portion of the second water channel forming member 20. The operation member 22 has its inner step portion 22b abutted against the outer step portion 20c of the second water channel forming member 20, whereby the downward relative displacement with respect to the second water channel forming member 20 is restricted. A retaining ring 46 is attached to the outer periphery of the second water channel forming member 20 above the outer step portion 20c. The operation member 22 is in contact with the retaining ring 46, so that upward relative displacement with respect to the second water channel forming member 20 is restricted. Thereby, the operation member 22 can rotate around the rotation axis in a state where relative displacement in the axial direction (vertical direction in the drawing) along the rotation axis is restricted with respect to the second water channel forming member 20. Supported.

  Two spiral grooves 22 c are formed on the inner peripheral surface of the operation member 22, and a convex portion 30 a that slidably contacts the spiral groove 22 c is formed on the outer peripheral surface of the outer cylindrical portion 30 of the first water channel forming member 18. It is formed. The first water channel forming member 18 is supported by the second water channel forming member 20 via the operation member 22 by the contact of the convex portion 30a with the spiral groove 22c of the operation member 22. When the operating member 22 is rotated with respect to the second water channel forming member 20, the convex portion 30 a of the first water channel forming member 18 slides along the spiral groove 22 c of the operating member 22, so that the operating member 22 is moved. The first water channel forming member 18 relatively moves in the vertical direction. At this time, the first water channel forming member 18 relatively moves in the vertical direction with proximity to or separation from the second water channel forming member 20. Thus, the spiral groove 22c of the operating member 22 and the convex portion 30a of the first water channel forming member 18 constitute a linear motion mechanism that converts the rotational motion of the operating member 22 into the linear motion of the first water channel forming member 18. .

  A convex first fitting portion 20d is formed on the outer peripheral surface of the lower portion 20b of the second water channel forming member 20, and a concave second fitting is formed on the outer cylindrical portion 30 of the first water channel forming member 18. Part 30b is formed. The first water channel forming member 18 cannot rotate with respect to the second water channel forming member 20 by the fitting of the fitting parts 20d and 30b. These fitting portions 20 d and 30 b constitute a co-rotation preventing mechanism for preventing the operation member 22 and the first water channel forming member 18 from co-rotating with respect to the second water channel forming member 20.

  A seal member 48 is disposed between the lower portion 20 b of the second water channel forming member 20 and the outer cylindrical portion 30 of the first water channel forming member 18. The seal member 48 is fixed to the second water channel forming member 20 by adhesion or the like. First, the seal member 48 serves to seal between the outer cylinder portion 30 of the first water channel forming member 18 and the second water channel forming member 20. Secondly, the seal member 48 has a role of blocking communication between the water passage 42 of the second water passage forming member 20 and the straight water discharge water passage 34 of the first water passage forming member 18. explain in detail.

  FIG. 4 is a diagram schematically illustrating different operating states of the water discharge component 10. As shown in FIG. 4A, when the operation member 22 is rotated with respect to the second water channel forming member 20, the first water channel forming member 18 is brought close to the direction Pa1 with respect to the second water channel forming member 20. The inner cylinder portion 28 of the first water channel forming member 18 contacts the seal member 48. Thereby, the communication between the water passage 42 of the second water passage forming member 20 and the straight water discharge water passage 34 of the first water passage forming member 18 is blocked. At this time, the water channel 42 of the second water channel forming member 20 and the shower water discharge channel 32 of the first water channel forming member 18 are communicated with each other. That is, only the shower water discharge channel 32 out of the shower water discharge channel 32 and the straight water discharge channel 34 is connected to the water flow channel 42 (hereinafter referred to as a first communication state). At this time, at least a part of the upstream end side of the shower water discharge channel 32 is in communication with the water channel 42.

  On the other hand, as shown in FIG. 4B, by rotating the operation member 22 with respect to the second water channel forming member 20, the first water channel forming member 18 is separated from the second water channel forming member 20 in the direction Pa <b> 2. As a result, the inner cylindrical portion 28 of the first water channel forming member 18 is separated from the seal member 48. Accordingly, the water passage 42 and the first water channel forming member 18 of the second water channel forming member 20 are passed through the gap 50 formed between the inner cylinder portion 28 of the first water channel forming member 18 and the second water channel forming member 20. It becomes the state (henceforth a 2nd communication state) in which the straight water discharging water channel 34 is connected. In the present embodiment, when in the second communication state, the water passage 42 of the second water passage forming member 20 and the shower water discharge water passage 32 of the first water passage forming member 18 are also communicated.

  In this manner, by moving the first water channel forming member 18 with respect to the second water channel forming member 20, the presence or absence of communication between the water channel 42 and the straight water discharge channel 34 is switched, and the first communication state and the first communication state are changed. The two-communication state is switched. The structure of the first water channel forming member 18, the structure of the second water channel forming member 20, the operation member 22, the seal member 48, and the like constitute a “switching mechanism” that realizes such a function.

  As shown in FIG. 4A, when in the first communication state, the water sent from the water passage 42 of the second water passage forming member 20 is not guided to the straight water discharge water passage 34 of the first water passage forming member 18, It is guided only to the plurality of shower holes 26a through the shower water discharge channel 32 (see the flow direction Pb1). Accordingly, a plurality of water discharge flows Qa are discharged downward from the plurality of shower holes 26a.

  As shown in FIG. 4B, when in the second communication state, the water sent from the water passage 42 of the second water passage forming member 20 passes through the straight water discharge water passage 34 of the first water passage forming member 18 to the water discharge hole 38. Guided (see flow direction Pc1). In the present embodiment, the water is also guided to the plurality of shower holes 26a through the shower water discharge water channel 32 of the first water channel forming member 18 (see the flow direction Pc2). At this time, from the water discharge hole 38, a single water flow that gradually narrows as described above is discharged in the flow direction Pc3. This single water flow has a cylindrical shape immediately after being discharged from the water discharge hole 38. The plurality of water flows discharged from the plurality of shower holes 26a pass through the inside of the tubular portion of the water flow discharged from the water discharge hole 38, and merge with the water flow discharged from the water discharge hole 38, so that a single unit is collected. A water discharge flow Qb is formed. That is, the unitary water discharge flow Qb is sent out by combining the water flows discharged from each of the plurality of shower holes 26a and the water discharge holes 38.

  Turning to the description of the valve device 24. FIG. 5 is an enlarged sectional view showing the valve device 24 together with the peripheral structure. The valve device 24 is provided so as to cross over the shower water discharge channel 32 described above. The valve device 24 is provided on the shower water discharge channel 32 at a location different from the route passing through the straight water discharge channel 34 from the water flow channel 42. The valve device 24 is for controlling the flow rate of water flowing out through its own interior. The valve device 24 of the present embodiment functions as a constant flow valve that restricts the flow rate of the fluid flowing out within a range having a preset flow rate as an upper limit by automatically adjusting the opening degree.

  The valve device 24 mainly includes a case 52, a body 54, and a coiled spring 56. The case 52 is fitted into the shower water discharge channel 32.

  FIG. 6 is a perspective view of the case 52. As shown in FIGS. 5 and 6, the case 52 includes a bottomed cylindrical main body 52 a and a columnar protrusion 52 b that protrudes from the main body 52 a toward the sprinkler 26. A storage chamber 53 is provided inside the main body 52 a, and the body 54 is stored in the storage chamber 53. The cylindrical portion of the main body 52a is provided with a body receiving portion 52c protruding inward, and the body 54 is supported by the body receiving portion 52c.

  As shown in FIG. 5, the protrusion 52 b of the case 52 has a role of maintaining a gap between the main body 52 a of the case 52 and the sprinkler 26, and hits the central region 26 b of the sprinkler 26 from the back side. Touch. A water chamber 58 is formed on the back side of the water sprinkling unit 26 between the case 52 and the main body 52 a. The water chamber 58 is partly formed on the back surface of the water sprinkling portion 26, and becomes a part of the shower water discharge channel 32. The water chamber 58 is provided in an annular shape around the protruding portion 52 b of the case 52. The water chamber 58 is for temporarily storing water that has passed through the valve device 24.

  The body 54 is provided with an internal flow path 54c extending from the inflow hole 54a to the outflow hole 54b. The body 54 has a bottomed cylindrical shape, and an opening end on one side thereof serves as an inflow hole 54a, and a plurality of outflow holes 54b are formed at the bottom thereof at intervals in the circumferential direction. The water sent from the water passage 42 of the second water passage forming member 20 flows in from the inflow hole 54a of the body 54, passes through the internal flow path 54c, and then flows out of the outflow hole 54b of the body 54.

  The coil spring 56 is disposed so as to cross the internal flow path 54 c of the body 54. The coil spring 56 functions as a valve body that can adjust the opening degree of the internal flow path 54c with its own operation. Since a constant flow valve using this type of coiled spring 56 as a valve body is known, only a brief description will be given here.

  When the coiled spring 56 is in an inelastically deformed state, the one end side portion is wound in a conical shape so that the other end side portion becomes a large diameter portion. An inner portion of the small diameter portion of the coil spring 56 is closed by the closing member 60. The large-diameter portion of the coiled spring 56 is fixed by being pressed toward the bottom surface of the body 54 by a cylindrical pressing member 62. The pressing member 62 is fixed to the body 54 using a snap-fit structure or the like.

  In the valve device 24 described above, when a small amount of water flows in the direction Pd1 from the primary inflow hole 54a, it passes between the windings of the coiled spring 56 and passes through the secondary outflow hole 54b with almost the same flow rate. Water flows out. When a large amount of water flows from the primary inflow hole 54a, the primary pressure acts on the surface (upper surface) facing the primary side of the coiled spring 56, and the coiled spring 56 receives the primary pressure to Elastically contracts and deforms toward the side. When the coiled spring 56 is contracted and deformed, the interval between the windings of the coiled spring 56 is narrowed, and the opening degree of the internal flow path 54c of the body 54 is gradually reduced. The flow rate of water passing through the internal flow path 54c of the body 54 decreases as the opening degree decreases, and is limited to a range with the set flow rate as an upper limit, and the water having the limited flow rate flows into the outflow hole 54b of the body 54. Out in the direction Pd2.

  Here, as shown in FIGS. 5 and 6, the main body portion 52 a of the case 52 has a water receiving portion 52 d that forms the bottom thereof. The water receiving portion 52d of the case 52 has a circular plate shape, and is provided on the opposite side of the water sprinkling portion 26 with the water chamber 58 of the shower water discharge channel 32 interposed therebetween. The water receiving portion 52d of the case 52 is at a position spaced from the outflow hole 54b of the body 54, and on the central axis La of the outflow hole 54b of the body 54, that is, at a position where the water flow flowing out of the outflow hole 54b abuts. Provided. The water receiving portion 52d of the case 52 is for receiving the water flow flowing out from the outflow hole 54b and diffusing it radially. Between the water receiving part 52d of the case 52 and the body 54, a diffusion chamber 52e for diffusing the water flow received by the water receiving part 52d is formed.

  In the main body 52 a of the case 52, a guide water channel 52 f that connects the diffusion chamber 52 e in the case 52 and the water chamber 58 is formed. The guiding water channel 52 f is for guiding the water flow that radially hits the water receiving portion 52 d of the case 52 to the water chamber 58. FIG. 5 shows the flow direction Pe of this water flow. The guiding water channel 52f of the present embodiment has an arc shape formed along the circumferential direction at the bottom of the main body portion 52a of the case 52, and is provided at intervals in the circumferential direction. The guiding water channel 52f is formed with a tapered surface 52g for directing the flow direction of the water flow radially diffusing radially toward the water chamber 58 side. The tapered surface 52g is formed on the inner peripheral surface of the case 52 provided so as to surround the central axis La of the outflow hole 54b passing between the body 54 and the water receiving portion 52d.

The operation of the water discharge component 10 will be described.
When water is sent from the water supply source to the water supply path 16 g of the apparatus main body 16, the water is supplied to the water discharge component 10. When water is supplied to the water discharge component 10, the water flows in through the water passage 42 of the second water channel forming member 20. When the water is sent from the water passage 42 of the second water passage forming member 20 in the first communication state described above, a plurality of water discharge flows Qa are discharged downward from the plurality of shower holes 26a (see FIG. 4A). ). When water is sent from the water passage 42 of the second water passage forming member 20 in the second communication state described above, a water flow is discharged from each of the plurality of shower holes 26a and the water discharge holes 38, and these water flows merge. A single water discharge flow Qb is sent out (see FIG. 4B).

The effect of the above water discharging component 10 is demonstrated.
In the water discharge part 10, the valve apparatus 24 is provided on the shower water discharge water channel 32 for introducing water into the plurality of shower holes 26a. Therefore, even when a large flow rate of water is sent from the water flow channel 42 of the second water channel forming member 20 to the shower water discharge channel 32, the flow rate is smaller than the large flow rate water on the primary side by way of the valve device 24. Water can be led to the plurality of shower holes 26a on the secondary side. For this reason, even when a large flow rate of water is sent from the water passage 42, the flow velocity of the discharged water flow discharged from the plurality of shower holes 26a can be suppressed, and the water splash at the landing point can be prevented. In particular, when the valve device 24 functions as a constant flow valve, if the water sent from the water passage 42 exceeds the set flow rate, even if the flow rate increases or decreases, a stable water discharge flow from the plurality of shower holes 26a. I can vomit.

  Moreover, even when the valve unit 16f of the water discharger 12 is set to a large opening, the flow rate of the discharged water discharged from the shower hole 26a can be suppressed. Therefore, in order to prevent water splashing at the landing point, there is no need to adjust the opening degree of the valve unit 16f using the lever 16d. The water discharger 12 can be used. In particular, when the valve device 24 functions as a constant flow valve, this advantage can be obtained effectively.

  In addition, when the communication state of the water discharge component 10 is switched from the first communication state to the second communication state, a large flow rate of discharged water can be discharged from the water discharge hole 38 through the straight water discharge water channel 34 that does not pass through the valve device 24, so that it is easy to use. can get. Therefore, when the communication state of the water discharge component 10 is switched to the first communication state, a large flow rate is discharged when switching to the second communication state while suppressing the increase in the flow rate of the discharged water flow and taking measures against water splashing. It becomes possible to spout water flow.

  In addition, when the water discharge component 10 is switched to the second communication state, a straight water discharge, that is, a single thick water flow is discharged from the water discharge hole 38. When discharging the water flow of shower water, that is, discharging a plurality of thin water flows, the flow velocity tends to increase because the hole cross-sectional area is small, and water splashes easily occur at the landing point. In this point, in this embodiment, when discharging the water flow of straight water discharge, since it passes through the water discharge hole having a larger hole cross-sectional area than the shower hole, the increase in the flow velocity can be suppressed, and the water at the water landing point is I can suppress it.

  Thus, according to the water discharge component 10 of this embodiment, while responding to the request for countermeasures against water splashing, the request for a large flow rate of discharged water can also be satisfied.

  Further, in the valve device 24, when the opening degree of the internal flow path 54c of the body 54 is reduced, the water flow passing through the internal flow path 54c of the body 54 is throttled, so that a high-speed water flow can flow out from the outflow hole 54b. There is sex. If an excessively high flow rate of water flow is led to the plurality of shower holes 26a as it is, there is a possibility that the flow rate distribution of the water flow discharged from the plurality of shower holes 26a is biased. For example, when the water flow that flows out from the outflow hole 54b of the valve device 24 flows toward the central region 26b of the water sprinkling part 26, a large flow rate of water flow is discharged from the shower hole 26a around the central region 26b, and on the outer peripheral side. A small flow velocity of water is discharged toward a certain shower hole 26a.

  In this regard, the valve device 24 of the present embodiment has a water receiving portion 52d for receiving and diffusing the water flow flowing out from the outflow hole 54b of the body 54. Therefore, even when a high-speed water flow flows out from the outflow hole 54b of the body 54, the flow rate of the water flow can be suppressed by receiving and diffusing the high-speed water flow in the water receiving portion 52d of the case 52. As a result, it becomes easy to equalize the water flow discharged from the plurality of shower holes 26a by suppressing the deviation of the flow velocity distribution.

  Further, the valve device 24 has a guiding water channel 52 f for guiding a water flow that radiates and strikes the water receiving portion 52 d to the water chamber 58. Therefore, water with a small flow velocity difference can be supplied to the entire water chamber 58 on the back side of the water sprinkling portion 26 from the guide water channel, and the flow velocity distribution of the water flow discharged from the plurality of shower holes 26a can be made more uniform.

Is possible. In the above-described embodiment, the contents that can be changed in the design are described with the notation of “embodiment”, “in the embodiment”, and the like. Changes are not unacceptable. Moreover, the hatching given to the cross section of drawing does not limit the material of the hatched object.

  Although the water discharging apparatus 12 demonstrated the example used for a kitchen, you may be used for a hand-washing machine, a washbasin, a bathroom, etc. When used in a hand-washing basin or basin, the water receiving tank 14 is constituted by a bowl. Although the apparatus fixing | fixed part 14a of the water discharging apparatus 12 demonstrated the example provided in the water receiving tank 14, it is not restricted to this, The back guard of a washstand etc. may be sufficient.

  As for the tubular body 16b of the water discharging apparatus 12, the water discharging component 10 is mounted | worn and the water supply path 16g for supplying water to the water discharging component 10 should just be provided in the inside. Although the tubular body 16b demonstrated the example by which the front end side part was hold | maintained so that attachment or detachment with respect to a root side part was carried out, the front end side part and the root side part may be integrated so that separation is impossible. Moreover, although the tubular body 16b demonstrated the example which comprises a water discharge pipe, you may comprise a shower head.

  Although the example in which the switching mechanism is configured by a combination of the first water channel forming member 18 and the like has been described, it is not limited thereto. For example, the switching mechanism may be a switching valve or the like provided on the water passage 42. This switching valve is a valve that can selectively switch the communication destination of the water passage 42 from the shower water discharge channel 32 and the straight water discharge channel 34. In this case, when in the second communication state described above, only the water passage 42 and the straight water discharge water passage 34 are communicated, and the communication between the water passage 42, the shower, and the water discharge water passage 32 is blocked.

  The valve apparatus 24 demonstrated the example which functions as a constant flow valve which restrict | limits to the range which made the setting flow volume the upper limit by adjusting an opening degree automatically. The valve device 24 may be any device that can control the flow rate of water flowing out through the inside thereof, and is not limited to one that functions as a constant flow valve. For example, a differential pressure valve that holds the pressure difference between the high-pressure primary pressure and the low-pressure secondary pressure at a set differential pressure, or an on-off valve that makes the flow rate of flowing water zero. In the case of the on-off valve, it is only necessary to open its own internal flow path 54c when it is in the aforementioned first communication state and to close its internal flow path 54c when it is in the aforementioned second communication state. In the case of an on-off valve, it may be opened and closed in conjunction with the switching operation from the first communication state to the second communication state by the switching mechanism. Moreover, although the valve apparatus 24 demonstrated the example which controls the flow volume of the outflow water by adjusting an opening degree automatically, you may adjust an opening degree manually.

  Although the valve device 24 illustrated what uses the coiled spring 56 as a valve body, the valve body is not specifically limited, Various valve bodies including a well-known thing may be used.

  Each of the plurality of shower holes 26 a and the water discharge holes 38 has been described as being disposed on the back side of the opening 40 a formed on the discharge surface 40 of the first water channel forming member 18, but these are formed on the discharge surface 40. May be.
