Japanese Patent No. 4066459

  In the water discharging device of Patent Document 1, a water passage that guides water to the water outlet is formed inside the device main body, and the water passage of the device main body is formed by a single component. Moreover, it is thought that the apparatus main body is integrally formed by the metal casting. In general, when a part having a hollow cross section is integrally formed with a single component, it is difficult to ensure the dimensional accuracy of the inner wall surface, and the surface roughness of the inner wall surface tends to be high. In particular, when the apparatus main body is integrally formed of a metal casting product, the inner wall surface remains the cast skin surface, so that the surface is likely to become rougher. If the surface roughness is high, the water flow flowing through the water passage is likely to be disturbed, and the shape of the water discharge flow is disturbed, which may impair the beauty.

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, when molding a portion having a hollow cross section, it is less difficult to mold by molding separately from multiple parts and exposing the inner wall surface to the external space than by integrally molding with a single part. It becomes easy to ensure the dimensional accuracy of the inner wall surface. Therefore, it becomes easy to suppress the surface roughness of the inner wall surface of the discharge passage, and it becomes easy to suppress the disturbance of the shape of the discharged water flow due to the surface roughness.

According to this aspect, even when a load that narrows the interval between the discharge passages is applied to the water discharge member, this interval can be maintained, so that it becomes easy to suppress the disturbance of the shape of the water discharge flow.

The interval holding unit may be disposed in the storage chamber.
According to this aspect, even if the water flow is divided by the interval holding unit, it becomes easy to join the divided water flow early before reaching the discharge port, and it is easy to suppress disturbance in the shape of the discharged water flow caused by the division of the water flow. Become.

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

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

The water discharge member may have a peripheral wall portion surrounding the discharge passage from three sides of the discharge passage in both the widthwise direction and the back side opposite to the discharge port. The first divided member and the second divided member are coupled by a plurality of fixtures arranged at intervals along the inner peripheral wall surface of the peripheral wall portion, and the plurality of fixtures are intermediate portions in the lateral direction of the water discharging member. It may be arranged so that the interval at both ends is narrower than the interval.

The first seal member 89 is detachably disposed in the groove 91 without being bonded.

  As shown in FIG. 5, the first seal member 89 is an inner peripheral wall surface 33b of the peripheral wall portion 49 of the discharge passage 33, and is continuous from the one opening edge 13a to the other opening edge 13a in the lateral width direction of the discharge port 13.

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. Accordingly, the first seal member 89 restricts the water in the discharge passage 33 from leaking outside through the mating surfaces 55. More specifically, leakage from the outer peripheral surface 19 c of the water discharge member 19 through the mating surface 55, or leakage from the insertion hole 85 or the like of the storage portion 83 is restricted.

  An annular second seal member 95 is interposed between the tip end surface 69d of the interval holding portion 69 and the upper wall surface 73 of the upper split member 53 facing the tip 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 tip 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 so as to follow the inner peripheral wall surface 33 b of the peripheral wall portion 49 of the water discharge member 19. That is, the plurality of fixtures 81 are also arranged in the same positional relationship, although not shown in the drawing. These fixtures 81 adjacent to each other in the lateral width direction X are such that the distance L2 between the opposite ends 19a of the water discharge member 19 in the width direction X is narrower than the distance L1 in the width direction X intermediate part 19b of the water discharge member 19. Placed in.

Operation | movement of the water discharging apparatus 10 which concerns on the above embodiment is demonstrated.
In the water discharge member 19, as shown in FIG. 4, water having a predetermined flow rate is pumped from the water supply pump 221 (see FIG. 2), and the water flows into the storage chamber 37 from the inlet 35 through the water conduit 17. The water is temporarily stored in the storage chamber 37 as stored water. When water is sent from the inlet 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 stored water is discharged through the throttle channel 39 by the water pressure. The discharged water flow W is discharged from the discharge port 13.

  Here, the water flowing in 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 height of the discharge passage 33 is made constant, and the flow from the inlet 35 to the inlet 39a of the throttle passage 39 is reached. The flow is effectively rectified so that the flow velocity is uniform in the lateral width direction X of the discharge passage 33.

The effect of the water discharging apparatus 10 which concerns on the above embodiment is demonstrated.
In the water discharge 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, in forming a part having a hollow cross section, it is more difficult to form by molding separately from multiple parts and exposing the inner wall surface to the external space than from integrally forming from a single part. It becomes low and it is easy to ensure the dimensional accuracy of the inner wall surface. Therefore, according to the water discharge member 19 according to the present embodiment, it is easy to suppress the surface roughness of the inner wall surfaces 71, 73, 33b of the discharge passage 33, and the disturbance of the shape of the water discharge flow W due to the surface roughness is suppressed. It becomes easy. In particular, since each of the divided members 51 and 53 is a resin molded product, a cast surface like a metal cast product does not occur on the inner wall surfaces 71, 73, and 33b of the discharge passage 33, and the surface roughness can be greatly 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 flowing from the inlet 35. Further, when the horizontally long water discharge W is spouted vigorously, the discharge passage 33 has a cross-sectional shape with a wide passage width and a low passage height. Therefore, the water flow flowing through the inside is also horizontally long and thin, 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 of the discharge port 13, that is, the width of the discharged water flow W increases, the minimum and maximum distances increase. The difference is likely to increase. Due to the above factors, the discharge water flow W discharged from the discharge port 13 tends to vary in the flow velocity in the lateral width direction X of the discharge port 13 and the shape thereof is easily disturbed when the storage chamber 37 is not provided in the discharge passage 33.

  In this respect, since the water discharge member 19 according to the present embodiment has the storage chamber 37 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. The flow can be effectively rectified so that the flow velocity in the width direction X is uniform. Therefore, the discharged water flow W discharged from the discharge port 13 can easily have a uniform flow velocity in the lateral width direction X, and by suppressing the disturbance of the shape, the discharged water flow W having excellent aesthetics can be obtained. Moreover, the further relaxing effect can be acquired by applying the spout water flow W excellent in aesthetics on a bather's shoulder.

  In addition, the storage chamber 37 is formed such that each of the pair of lower wall surface 71 and upper wall surface 73 facing the discharge passage 33 expands 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 separated. As a result, the water pressure of the stored water in the storage chamber 37 can be lowered and the flow rate thereof can be easily lowered, and the flow rate in the lateral width direction X can be rectified more effectively in the storage chamber 37.

  Moreover, since the water discharging member 19 has the space | interval holding | maintenance part 69 arrange | positioned in the discharge channel 33, as shown in FIG. 8, there exists the following advantage. In the water discharge device 10, a pillow member may be disposed on the upper surface of the device body 11, and a bather may use the head on the pillow member. In this case, a load that narrows the interval between the discharge passages 33 is applied to the water discharge member 19. If the interval between the discharge passages 33 is narrowed 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 is horizontally long and thin as described above, it is easily affected by a change in the interval of the discharge passage 33. In this regard, in the present embodiment, the interval between the discharge passages 33 can be held by the interval holding unit 69, so that even when the above-described load is applied to the water discharge member 19, it becomes easy to suppress the disorder of the shape of the water discharge flow W. In particular, each of the divided members 51 and 53 is a resin molded product whose strength is difficult to ensure, but even in that case, there is a great advantage in that the change in the interval of the discharge passage 33 due to the load can be suppressed.

  At this time, if the interval holding unit 69 is disposed in the discharge passage 33, the water flow is divided by the interval holding unit 69. In this regard, the interval holding unit 69 according to the present embodiment is disposed in the storage chamber 37 in which 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 flow is likely to be merged at an early stage before reaching the discharge port 13, and the shape disturbance of the discharged water flow W due to the division of the water flow can be easily suppressed. Become.

  Further, if 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 divided members 51 and 53 are assembled. In particular, the first seal member 89 according to the present embodiment has a complicated shape that surrounds the discharge passage 33 from three sides. Therefore, if the first seal member 89 is attached to the upper divided member 53 by bonding, the assembling work is further complicated. In this respect, since the first seal member 89 according to the present embodiment is disposed in the groove portion 91 of the lower divided member 51, the upper seal is left in a state where the first seal member 89 is placed in the groove portion 91 in a non-adhesive manner. The member 53 can be assembled to the lower divided member 51, and workability at the time of assembly is improved.

  Further, the water discharge member 19 may be subjected to a bending force that warps in the vertical direction due to screwing of the fixing member 231 (see FIG. 4), water pressure in the discharge passage 33, or the like. Here, the water discharge member 19 has a depth dimension smaller than the horizontal width dimension as shown in FIG. 5 in order to suppress the occupied space while discharging a wide discharge water flow W. Therefore, the distance from the force point to which the bending force is applied, that is, the distance from the force point to the action point tends to be longer at both ends 19a than the width direction X intermediate portion 19b of the water discharge member 19, and a larger bending moment acts accordingly. 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 narrower than the interval L1 at the intermediate portion 19b of the water discharging member 19. The fixing degree at both end portions 19a is higher than that of the intermediate portion 19b. Therefore, while the interval L1 of the fixtures 81 is widened and the number thereof is suppressed at the intermediate portion 19b of the water discharging member 19, the interval L2 of the fixtures 81 can be narrowed at both ends 19a to effectively resist the bending moment. The state where the divided members 51 and 53 are coupled can be stably maintained.

  Moreover, since each division member 51 and 53 is a resin molded product, the water discharging apparatus 10 of the variation of various colors can be provided by mixing a coloring agent with a resin composition. Further, since each of the divided members 51 and 53 is a resin molded product, post-processing such as anticorrosion treatment becomes unnecessary, and productivity is improved.

  Although the upper divided member 53 and the lower divided member 51 have been described as examples of resin molded products, other metal cast products or the like may be used. Even 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 lowered 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 a shape obtained by dividing the water discharge member 19 in the vertical direction. In addition to these, they may have a shape divided in the width direction X. In any case, each divided member may have a shape divided in a direction intersecting with the direction from the storage chamber 37 toward the discharge port 13.

  The lower divided member 51 and the upper divided member 53 are assembled so as to be detachable by the fixture 81, but the present invention is not limited to this, and may be assembled by snap fit or the like. Although the inflow port 35 is formed on the lower wall surface 71 of the discharge passage 33, it may be formed on the wall surface of the discharge passage 33, and may be formed on the upper wall surface 73, the back wall surface, or the side wall surface.

  Although the example in which the interval holding unit 69 is integrally formed so as to rise from the lower divided member 51 has been described, it may be formed integrally with the upper divided member 53, or separately from each divided member 51, 53. It may be provided.

  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, but is not limited thereto. The positioning structure 79 may be configured by, for example, a guide protrusion that is provided on one of the lower split member 51 and the upper split member 53 and protrudes toward the other. In this case, when the divided members 51 and 53 are assembled, they are positioned such that the other of them is guided by the guide convex portion. Further, in the positioning structure 79, the example in which the positioning convex portion 77 is provided in the upper split member 53 and the positioning concave portion 75 is provided in the lower split member 51 has been described. The positioning protrusion 77 may be provided on the member 51.

  The fixing device 81 has been described as being stored in the storage portion 83 provided in the lower split member 51, but may be stored in the storage portion 83 provided in the upper split member 53. In any case, the storage portion 83 is provided in one of the lower divided member 51 and the upper divided member 53 at a location corresponding to the peripheral wall portion 49 surrounding the discharge passage 33, and the attached portion 87 is provided in the other.
