Japanese Patent No. 4066459

  In the water discharge device of Patent Document 1, a water passage for guiding water to a water discharge port is formed inside the device main body, and the water passage of the device main body is formed by a single component. Further, it is considered that the apparatus main body is integrally formed of a metal casting. In general, when a portion having a hollow cross section is integrally formed by a single component, it is difficult to secure the dimensional accuracy of the inner wall surface, and the surface roughness of the inner wall surface tends to increase. In particular, when the apparatus main body is integrally formed from a metal casting, the inner wall surface remains as a casting surface, so that the surface tends to be further roughened. When the surface roughness is high, the water flow flowing through the water passage becomes easily disturbed, and the shape of the water discharge flow is disturbed, which may impair the aesthetic appearance.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a technique capable of suppressing disturbance of the shape of a water discharge flow.

Each of the throttle passages is defined by the first divided member and the second divided member.
According to this aspect, when each divided member is disassembled, the inner wall surface of the discharge passage can be exposed to the external space from the discharge port to the storage chamber. In general, in molding a part having a hollow cross section, it is less difficult to mold a plurality of parts separately so that the inner wall surface is exposed to an external space than to integrally mold a single part. Therefore, it becomes easy to secure the dimensional accuracy of the inner wall surface. Therefore, it is easy to suppress the surface roughness of the inner wall surface of the discharge passage, and it is easy to suppress the disturbance of the shape of the water discharge flow due to the surface roughness.

According to this aspect, the water pressure in the storage chamber is reduced, and the flow velocity thereof is easily reduced, so that the flow can be effectively rectified so that the flow velocity becomes uniform in the storage chamber.

The water discharging member may further include an interval holding unit that is disposed in the discharge passage and that holds an interval between a pair of wall surfaces facing the discharge passage.
According to this aspect, even when a load that narrows the interval between the discharge passages is applied to the water discharging member, the distance can be maintained, so that the shape of the water discharge flow can be easily suppressed.

The spacing unit may be arranged in the storage chamber.
According to this aspect, even if the water flow is divided by the interval holding unit, the divided water flows are easily merged early before reaching the discharge port, and it is easy to suppress the disturbance of the shape of the discharged water flow due to the divided water flow. Become.

According to this aspect, the upper division member can be assembled to the lower division member while the seal member is mounted in the groove portion in a non-adhesive state, and workability at the time of assembly is improved.

The water discharging member may have a positioning structure for positioning the first divided member and the second divided member when assembling the first divided member and the second divided member.
According to this aspect, when assembling the divided members, they can be easily positioned, and workability at the time of assembling is improved.

The water discharge member may have a peripheral wall portion surrounding the discharge passage from three sides, that is, both sides in the width direction of the discharge passage and the back side opposite to the discharge port. The first divided member and the second divided member are joined by a plurality of fixing members arranged at intervals so as to be along the inner peripheral wall surface of the peripheral wall portion, and the plurality of fixing members are provided at both ends in the width direction of the water discharging member. May be arranged so that the interval at the intermediate portion is narrower than the interval.

A hollow space 29 is provided between the top surface 25 and the passage 23. The lighting device 31 is attached to the lighting attachment portion 27. The illumination device 31 projects colored light or white light of a predetermined wavelength forward. This is emitted to the water discharge stream W, a bather, etc., and a good visual effect is obtained.

  A plurality of inflow ports 35 for feeding water into the storage chamber 37 are formed in the lower wall surface 71 of the discharge passage 33. Water flows into the storage chamber 37 from the upstream water conduit 17 through the inflow port 35, and the water is temporarily stored as stored water. The storage chamber 37 is formed such that a pair of lower wall surfaces 71 and an upper wall surface 73 that are vertically opposed to the discharge passage 33 are widened in a direction away from the inlet 39 a of the throttle channel 39. The lower wall surface 71 and the upper wall surface 73 face in a direction Z orthogonal to the width direction X of the discharge passage 33.

Assuming that the dimensions of the discharge passage 33 in the width direction X and the front-rear direction Y are the passage width and the depth dimension, the discharge passage 33 is formed so that the depth dimension is smaller than the passage width in plan view. Further, the discharge passage 33 is formed to be laterally long so that the cross section (not shown) has a passage width larger than the passage height. The side wall surfaces 33a on both sides in the lateral width direction X of the discharge passage 33 are formed so that the passage width of the discharge passage 33 becomes wider as it approaches the discharge port 13 side from the back side of the storage chamber 37.

FIG. 6 is an exploded perspective view of the water discharging device 10.
The water discharging member 19 is configured by assembling a lower divided member 51 as a first divided member and an upper divided member 53 as a second divided member. Each of the dividing members 51 and 53 is a resin molded product, and has a shape vertically divided with the peripheral wall portion 49 of the water discharging member 19 as a boundary.

FIG. 7A is a side sectional view showing the discharge passage 33 in an enlarged manner, and FIG. 7B shows a state where each of the divided members 51 and 53 is disassembled.
Each of the divided members 51 and 53 has a mating surface 55 facing the vertical direction Z at their boundary. The mating surface 55 is provided so as to surround the discharge passage 33 from three sides, similarly to the peripheral wall portion 49. Each of the divided members 51 and 53 is assembled with the mating surfaces 55 abutting each other.

  The lower divided member 51 has a first passage defining portion 57 that partially defines each of the storage chamber 37, the throttle channel 39, and the discharge port 13. The first passage defining portion 57 is formed by the lower wall surface 71 of the discharge passage 33 and a part of the inner peripheral wall surface 33 b of the peripheral wall portion 49. The first passage defining portion 57 is formed in a concave shape that opens upward from the front end side to the back side. The upper division member 53 also has a second passage defining portion 59 that partially defines each of the storage chamber 37, the throttle channel 39, and the discharge port 13. The second passage defining portion 59 is formed by the upper wall surface 73 of the discharge passage 33 and a part of the inner peripheral wall surface 33b of the peripheral wall portion 49. The second passage defining portion 59 is formed in a convex shape so as to protrude downward in a region S1 from the front end side to an intermediate position in the front-rear direction Y. In addition, the second passage defining portion 59 is formed in a concave shape that opens downward in a region S2 extending from an intermediate position in the front-rear direction Y to the back side. Each of the discharge port 13, the storage chamber 37, and the throttle channel 39 is defined by both the first passage defining portion 57 and the second passage defining portion 59.

  When the division members 51 and 53 are disassembled, the respective wall surfaces 71, 73 and 33 b serving as the inner wall surfaces of the discharge passage 33 are exposed to the external space 235. At this time, the lower wall surface 71 of the lower division member 51 and the upper wall surface 73 of the upper division member 53 are exposed so as to face the external space 235.

  In the storage chamber 37 of the discharge passage 33, as shown in FIG. 5A and FIG. 6, an interval holding section 69 as a columnar body is arranged. A plurality of the interval holding parts 69 are arranged at intervals in the horizontal width direction X.

  As shown in FIG. 5B, the outer peripheral surface 69a of the spacing member 69 is formed in a circular shape in plan view. In other words, the outer peripheral surface 69 a of the interval holding section 69 is formed so as to be streamlined with respect to the water flow flowing in the discharge passage 33. More specifically, the width gradually increases as the upstream portion 69b moves toward the downstream side (lower side in the figure) of the water flowing in the discharge passage 33, and the width increases as the downstream portion 69c moves toward the downstream side. It is formed so as to become gradually smaller.

FIG. 8 is a sectional view taken along line BB of FIG. The shape of the lower divided member 51 described in this drawing matches the cross section taken along line CC of FIG. 5A.
The space holding portion 69 rises from the lower wall surface 71 of the lower division member 51, and its upper surface contacts the upper wall surface 73 of the upper division member 53. As a result, the space holding section 69 holds the space between the upper wall surface 73 and the lower wall surface 71 that face the discharge passage 33 up and down.

  As shown in FIG. 3, the water discharging member 19 has a positioning structure 79 including a positioning concave portion 75 and a positioning convex portion 77. The positioning structure 79 is provided at both ends 19 a in the lateral width direction X of the water discharging member 19.

FIG. 9A is a diagram showing a part of a cross section taken along line DD of FIG. 3, and FIG. 9B shows a state where each of the divided members 51 and 53 is disassembled. The shape of the lower split member 51 described in this drawing matches the cross section taken along line EE in FIG.
The positioning recess 75 is formed as a bottomed hole that opens in the mating surface 55 of the lower split member 51. The positioning projection 77 is provided on the upper division member 53 at a position corresponding to the positioning recess 75, and is formed as a boss protruding from the mating surface 55.

  When assembling the lower divided member 51 and the upper divided member 53, as shown in FIG. 9B, the operator aligns the divided members 51 and 53 while positioning the corresponding divided recesses 75 in the plurality of positioning recesses 75. The protrusion 77 is inserted. Thereby, when assembling the divided members 51 and 53, they can be easily positioned, and workability at the time of assembling is improved.

  As shown in FIG. 8, the lower division member 51 is provided with a plurality of storage portions 83 for storing fixing members 81 such as screws at locations corresponding to the peripheral wall portion 49. In addition, a storage portion 83 for storing the fixture 81 is also provided in the interval holding portion 69 of the lower divided member 51. An insertion hole 85 into which the fixing tool 81 is inserted is formed in each storage section 83. A screw hole is provided in the upper division member 53 at a position corresponding to the insertion hole 85 as the attached portion 87. The front end portion 81a of the fixture 81 is fixed to the attached portion 87 by screwing or the like. Each of the division members 51 and 53 is detachably connected by these fixing tools 81.

  As shown in FIG. 9A, the storage portion 83 of the lower division member 51 includes one provided coaxially with the positioning concave portion 75. The mounting portion 87 of the upper divided member 53 corresponding to the insertion hole 85 of the storage portion 83 is provided on the positioning projection 77.

  As shown in FIG. 8, the lower divided member 51 and the upper divided member 53 have a first seal member 89 interposed between the plurality of mating surfaces 55. A groove 91 into which the first seal member 89 can be fitted is formed in the mating surface 55 of the lower split member 51, and the first seal member 89 is disposed in the groove 91. The first seal member 89 is detachably disposed in the groove 91 without bonding.

  As shown in FIG. 5, the first seal member 89 is an inner peripheral wall surface 33 b of the peripheral wall portion 49 of the discharge passage 33, and extends from one opening edge 13 a in the width direction of the discharge port 13 to the other opening edge 13 a. It is formed so as to extend along the peripheral wall surface 33b. The first seal member 89 is disposed so as to surround the discharge passage 33 from three sides, that is, both sides in the width direction and the back side.

  Returning to FIG. 8, a projection 93 is formed on the mating surface 55 of the upper divided member 53 at a position facing the first seal member 89 in the vertical direction Z. The protrusion 93 is formed as a protrusion along the direction in which the first seal member 89 extends. The protrusion 93 presses the first seal member 89, and the space between the plurality of mating surfaces 55 is sealed by the first seal member 89. Thus, the first seal member 89 restricts the water in the discharge passage 33 from leaking outside through the space between the mating surfaces 55. More specifically, the leakage from the outer peripheral surface 19c of the water discharging member 19 through the mating surface 55 and the leakage from the insertion hole 85 of the storage portion 83 are restricted.

  Note that an annular second seal member 95 is interposed between the distal end surface 69d of the interval holding portion 69 and the upper wall surface 73 facing the upper end divided member 53. Similarly to the first seal member 89, the second seal member 95 is non-adhesively detachably disposed in an annular groove 97 formed on the distal end surface 69d. An annular protrusion 99 is formed on the upper wall surface 73 at a position facing the second seal member 95 in the vertical direction Z. The protrusion 99 also presses the second seal member 95, and the space between the front end surface 69 d and the upper wall surface 73 is sealed by the second seal member 95.

  As shown in FIG. 5, the plurality of insertion holes 85 are arranged at intervals along the inner peripheral wall surface 33 b of the peripheral wall portion 49 of the water discharging member 19. That is, the plurality of fixtures 81 are also arranged in the same positional relationship, although not shown in the drawing. The distance between adjacent fixing members 81 in the width direction X is smaller than the distance L1 between the water discharge members 19 at the both ends 19a in the width direction X of the water discharge member 19 than the distance L1 at the intermediate portion 19b in the width direction X. Placed in

The operation of the water discharge device 10 according to the above embodiment will be described.
In the water discharging member 19, as shown in FIG. 4, water of a predetermined flow rate is pressure-fed from a water supply pump 221 (see FIG. 2), and the water flows into the storage chamber 37 from the inflow port 35 through the water channel 17. Is temporarily stored in the storage chamber 37 as stored water. When the water is sent from the inflow port 35 in a state where the stored water is stored in the storage chamber 37, the stored water in the storage chamber 37 is pressurized. And the discharged water W is discharged from the discharge port 13.

  Here, the water flowing from the inflow port 35 on the upstream side flows so as to spread from the inflow port 35 toward the inlet 39 a of the throttle channel 39. When this water flow passes through the storage chamber 37, the flow velocity is greatly reduced as compared with the case where the passage height of the discharge passage 33 is kept constant, and the water flow reaches the inlet 39a of the throttle passage 39 from the inlet 35. The flow is effectively rectified so that the flow velocity becomes uniform in the width direction X of the discharge passage 33.

The operation and effect of the water discharge device 10 according to the above embodiment will be described.
In the water discharging member 19, each of the discharge port 13, the storage chamber 37, and the throttle channel 39 is defined by both the upper divided member 53 and the lower divided member 51. Therefore, when the divided members 51 and 53 are disassembled, the inner wall surfaces 71, 73 and 33 b of the discharge passage 33 can be exposed to the external space 235 from the discharge port 13 to the storage chamber 37. In general, when molding a part having a hollow cross section, it is more difficult to form a part having a hollow cross-section so that the inner wall surface is exposed to an external space than to form the part integrally with a single part, rather than integrally molding the part. Therefore, the dimensional accuracy of the inner wall surface can be easily secured. Therefore, according to the water discharge member 19 according to the present embodiment, the surface roughness of the inner wall surfaces 71, 73, and 33b of the discharge passage 33 can be easily suppressed, and the shape of the water discharge flow W due to the surface roughness is suppressed. It will be easier. In particular, since each of the divided members 51 and 53 is a resin molded product, a casting surface like a metal casting does not occur on the inner wall surfaces 71, 73, and 33b of the discharge passage 33, and the surface roughness thereof can be largely suppressed.

  In addition, the water flow supplied into the discharge passage 33 is likely to be disturbed due to a sudden change in the cross-section of the flow path when the water flows from the inflow port 35. Further, in order to discharge the horizontally long water discharge W vigorously, the discharge passage 33 has a cross-sectional shape having a wide passage width and a low passage height. Therefore, the water flow flowing through the inside of the discharge passage 33 also has a horizontal shape and a thin shape, and is easily affected by turbulence in the discharge passage 33 and catching of foreign matter. The distance from the inflow port 35 to the discharge port 13 varies depending on the position of the discharge port 13 in the width direction. As the width dimension of the discharge port 13, that is, the width dimension of the water discharge stream W increases, the minimum distance and the maximum distance thereof increase. Differences tend to be large. Due to the above-described factors, the flow rate of the discharged water flow W discharged from the discharge port 13 tends to fluctuate in the lateral width direction X of the discharge port 13 when the storage passage 37 is not provided in the discharge passage 33, and the shape thereof is easily disturbed.

  In this regard, in the water discharging member 19 according to the present embodiment, since the storage chamber 37 is formed in the discharge passage 33, the flow velocity of the water flow in the discharge passage 33 decreases when passing through the storage chamber 37, and The flow can be effectively rectified so that the flow velocity in the width direction X becomes uniform. Therefore, it is easy to make the flow rate of the discharged water flow W discharged from the discharge port 13 uniform in the lateral width direction X, and it is possible to make the discharged water flow W excellent in aesthetic appearance by suppressing the disturbance of the shape. Further, a more relaxing effect can be obtained by, for example, applying the spouting water stream W having an excellent appearance to the bather's shoulder.

  The storage chamber 37 is formed such that the lower wall 71 and the upper wall 73 facing each other of the discharge passage 33 extend in a direction away from the inlet 39 a of the throttle channel 39. Therefore, it is easier to increase the internal volume of the storage chamber 37 than when the storage chamber 37 is formed so that only one of the pair of wall surfaces 71 and 73 is apart from each other. As a result, the water pressure of the stored water in the storage chamber 37 is reduced, and the flow velocity thereof is also easily reduced, so that the flow velocity in the lateral width direction X in the storage chamber 37 can be more effectively rectified.

  Further, as shown in FIG. 8, the water discharging member 19 has the following advantages because it has the interval holding portion 69 arranged in the discharge passage 33. The water spouting device 10 has a pillow member arranged on the upper surface of the device main body 11, and a bather may use the head thereon. In this case, a load is applied to the water discharging member 19 so as to narrow the interval between the discharge passages 33. When the distance between the discharge passages 33 is reduced by this load, the shape of the discharged water flow W may be disturbed. In particular, since the water flow flowing in the discharge passage 33 has a horizontally long and thin shape as described above, it is easily affected by a change in the interval between the discharge passages 33. In this regard, in the present embodiment, since the interval between the discharge passages 33 can be held by the interval holding section 69, even when the above-described load is applied to the water discharge member 19, the shape of the water discharge flow W can be easily suppressed. In particular, each of the divided members 51 and 53 is a resin molded product whose strength is difficult to secure, but in this case, there is a great advantage in that the change in the interval between the discharge passages 33 due to the load can be suppressed.

  At this time, when the interval holding section 69 is arranged in the discharge passage 33, the water flow is divided by the interval holding section 69. In this regard, the interval holding unit 69 according to the present embodiment is disposed in the storage chamber 37 where the flow rate of the water flow is slow and the distance to the discharge port 13 is farther than the throttle channel 39. Therefore, even if the water flow is divided by the interval holding unit 69, the divided water flows are easily merged early before reaching the discharge port 13, and the shape of the discharged water flow W due to the divided water flow is easily suppressed. Become.

  In addition, when the first seal member 89 is attached to the upper divided member 53 without bonding, the first seal member 89 is easily detached when the respective divided members 51 and 53 are assembled. In particular, since the first seal member 89 according to the present embodiment has a complicated shape that surrounds the discharge passage 33 from three sides, if the first seal member 89 is attached to the upper divided member 53 by bonding, the assembling work becomes more troublesome. In this regard, since the first seal member 89 according to the present embodiment is disposed in the groove portion 91 of the lower split member 51, the first split member 89 is divided into upper portions while the first seal member 89 is placed in the groove portion 91 without being bonded. The member 53 can be assembled to the lower divided member 51, and workability at the time of assembling is improved.

  In addition, a bending force that warps in the vertical direction may be applied to the water discharging member 19 due to the screwing of the fixing member 231 (see FIG. 4) or the water pressure in the discharge passage 33. Here, in order to suppress the occupied space of the water discharging member 19 while discharging the water discharging flow W having a wide width, the depth dimension is smaller than the width dimension as shown in FIG. Therefore, the distance from the point of application of the bending force, that is, the distance from the point of application of the bending force, that is, the distance from the point of application, is more likely to be greater at both ends 19a than at the intermediate portion 19b in the lateral width direction X of the water discharging member 19, and a larger bending moment acts. Easy to do. In this regard, in the present embodiment, the plurality of fixtures 81 (not shown in the figure) are arranged such that the interval L2 at both ends 19a is smaller than the interval L1 at the intermediate portion 19b of the water discharging member 19. The degree of fixation at both ends 19a is higher than that at the intermediate portion 19b. Therefore, in the middle portion 19b of the water discharging member 19, the spacing L1 of the fixing members 81 is widened to suppress the number thereof, and at the both end portions 19a, the spacing L2 of the fixing members 81 is narrowed to effectively resist the bending moment. The state in which the divided members 51 and 53 are connected can be stably maintained.

  Further, since each of the divided members 51 and 53 is a resin molded product, by mixing a colorant into the resin composition, it is possible to provide the water discharging device 10 of various color variations. Further, since each of the divided members 51 and 53 is a resin molded product, post-processing such as anticorrosion treatment is not required, and productivity is improved.

In any case, the installation surface 217 may be provided on the base, and the water discharge device 10 may be installed on the installation surface 217.

  The discharge port 13 is formed in a horizontally elongated slit shape, and the discharge passage 33 is formed in a horizontal direction in a direction in which the discharge port 13 extends. These shapes are not limited thereto, and may be formed, for example, in a circular shape.

  Although the example in which the upper divided member 53 and the lower divided member 51 are resin molded products has been described, other metal cast products or the like may be used. Also in this case, since the passage section 23 having a hollow cross section is configured by assembling a plurality of parts, the surface roughness can be easily reduced by post-processing such as cutting and polishing the inner wall surface of the discharge passage 33 by disassembling them.

  The upper divided member 53 and the lower divided member 51 have been described as the first divided member and the second divided member having the shape of the water discharge member 19 divided vertically. These may have a shape divided in the lateral width direction X in addition to the above. In any case, each divided member may have a shape divided in a direction intersecting the direction from the storage chamber 37 to the discharge port 13.

  The lower divided member 51 and the upper divided member 53 are removably assembled by the fixture 81, but are not limited thereto, and may be assembled by snap fitting or the like. The inflow port 35 is formed on the lower wall surface 71 of the discharge passage 33, but may be formed on the wall surface of the discharge passage 33, and may be formed on the upper wall surface 73, the inner wall surface, or the side wall surface.

  Although the example in which the interval holding portion 69 is integrally formed so as to stand up from the lower divided member 51 has been described, it may be formed integrally with the upper divided member 53, or separately from the divided members 51 and 53. May be provided.

  Although the example in which the positioning structure 79 is configured by the combination of the positioning convex portion 77 and the positioning concave portion 75 has been described, the present invention is not limited to this. For example, the positioning structure 79 may be provided on one of the lower divided member 51 and the upper divided member 53, and may be configured by a convex portion for guide protruding toward the other. In this case, when assembling the divided members 51 and 53, the other of them is positioned so that the other of them is guided by the guide projection. Also, the positioning structure 79 has been described in which the positioning projections 77 are provided on the upper division member 53 and the positioning recesses 75 are provided on the lower division member 51. The positioning protrusion 77 may be provided on the member 51.

  Although the example in which the fixing tool 81 is stored in the storage portion 83 provided in the lower divided member 51 has been described, the fixing tool 81 may be stored in the storage portion 83 provided in the upper divided member 53. In any case, the storage portion 83 is provided on one of the lower divided member 51 and the upper divided member 53 at a position corresponding to the peripheral wall portion 49 surrounding the discharge passage 33, and the attached portion 87 is provided on the other.
