Japanese Patent No. 4066459

In the water discharge device of Patent Document 1, a water passage for guiding water to the 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 main body of the device is integrally molded by a metal casting. In general, when a portion having a hollow cross section is integrally molded by a single part, it is difficult to secure the dimensional accuracy of the inner wall surface thereof, and the surface roughness of the inner wall surface tends to be high. In particular, when the main body of the apparatus is integrally molded with a metal casting, the inner wall surface remains as the cast surface, so that the surface tends to be 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 spoil 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 turbulence in the shape of a water discharge stream.

In order to solve the above problems, the water discharge device according to an embodiment of the present invention includes a water discharge member in which a discharge passage is formed inside, and the discharge passage has a discharge port for discharging water and water flowing in from the upstream side. The water discharge member is formed by assembling the first division member and the second division member, and is formed by a storage chamber for storing water and a throttle flow path for sending water in the storage chamber to the discharge port. And each of the throttle flow paths is defined by the first dividing member and the second dividing 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 range of the storage chamber. In general, when molding a part having a hollow cross section, it is less difficult to mold a part having a hollow cross section by separately molding a plurality of parts so that the inner wall surface is exposed to an external space, rather than integrally molding a single part. Therefore, it becomes easy to secure 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 disorder of the shape of the discharge water flow due to the surface roughness.

The storage chamber may be formed so that each of the pair of wall surfaces facing each other in the discharge passage spreads in a direction away from the entrance of the throttle passage.
According to this aspect, the water pressure in the storage chamber can be lowered, the flow velocity thereof can be easily lowered, and the flow velocity can be effectively rectified so as to be uniform in the storage chamber.

The water discharge member may further have an interval holding portion which is arranged in the discharge passage and holds the distance between the pair of wall surfaces facing each other in the discharge passage.
According to this aspect, even when a load that narrows the interval of the discharge passage 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 discharge flow.

The interval holding portion may be arranged in the storage chamber.
According to this aspect, even if the water flow is divided by the interval holding portion, it is easy for the divided water flow to merge at an early stage before reaching the discharge port, and it is easy to suppress the disturbance of the shape of the discharge water flow due to the division of the water flow. Become.

The first dividing member and the second dividing member may have a plurality of mating surfaces that are abutted against each other, and a sealing member that is interposed between the plurality of mating surfaces and seals between the plurality of mating surfaces. ..
According to this aspect, it is possible to regulate the leakage of water in the discharge passage to the outside through the mating surfaces.

The first dividing member and the second dividing member are an upper dividing member and a lower dividing member having a shape in which the water discharge member is vertically divided, and a plurality of mating surfaces are provided so as to face each other in the vertical direction. , It may be arranged in the groove formed in the mating surface of the lower split member.
According to this aspect, the upper split member can be assembled to the lower split member while the seal member is placed in the groove portion without adhesion, and the workability at the time of assembly 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 of the divided members, and the workability at the time of assembling is improved.

The water discharge member may have peripheral wall portions surrounding the discharge passage from three sides, one on both sides in the width direction of the discharge passage and the other on the back side opposite to the discharge port. The first dividing member and the second dividing member are connected 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 connected at both ends in the width direction of the water discharge member. It may be arranged so that the interval in the middle portion is narrower than the interval of.
According to this aspect, in the middle part of the water discharge member, the distance between the fixtures is widened to reduce the number of fixtures, and at both ends, the distance between the fixtures is narrowed to effectively resist the bending moment, and each dividing member can be effectively resisted. The combined state can be stably maintained.

The first divided member and the second divided member may be resin molded products.
According to this aspect, a cast surface surface unlike that of a metal cast product is not generated on the inner wall surface of the discharge passage, and the surface roughness can be suppressed more than that of a metal cast product.

The discharge port may be formed in a horizontally long slit shape, and the discharge passage may be formed horizontally in the direction in which the discharge port extends.

The exterior cover 21 is provided so as to cover the lighting device 31 from above and also to cover the lateral width direction X both ends 19a (see FIG. 3) of the water discharge member 19 from the front.

A discharge passage 33 including a discharge port 13 is formed in the passage portion 23. The discharge passage 33 communicates with the headrace 17 on the upstream side and the external space 235 on the downstream side. The discharge passage 33 has a shape horizontally elongated in the extending direction of the discharge port 13, and is formed by the discharge port 13, the storage chamber 37 described later, and the throttle flow path 39.

A plurality of inflow ports 35 for feeding water into the storage chamber 37 are formed on the lower wall surface 71 of the discharge passage 33. Water flows into the storage chamber 37 from the headrace 17 on the upstream side through the inflow port 35, and the water is temporarily stored as the storage water. The storage chamber 37 is formed so that a pair of lower wall surfaces 71 and upper wall surfaces 73 facing each other vertically in the discharge passage 33 spread in a direction away from the inlet 39a of the throttle flow path 39. The lower wall surface 71 and the upper wall surface 73 face each other in the direction Z orthogonal to the lateral width direction X of the discharge passage 33.

The throttle flow path 39 is formed so that the passage height, which is the distance between the pair of lower wall surfaces 71 and the upper wall surface 73, is smaller than that of the storage chamber 37. The throttle flow path 39 is formed at a substantially constant passage height from the inlet 39a to the discharge port 13. The stored water in the storage chamber 37 is sent out to the discharge port 13 through the throttle flow path 39. When the stored water is squeezed through the squeezing flow path 39, the flow velocity is increased, and the discharge water flow W is vigorously discharged from the discharge port 13.

FIG. 5A is a plan view showing the discharge passage 33, and FIG. 5B is a plan view of the interval holding portion 69 described later. This figure is also a plan view of the lower split member 51, which will be described later.
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 a plan view. Further, the discharge passage 33 is formed horizontally so that its cross section (not shown) has a passage width larger than the passage height. The side wall surfaces 33a on both sides of the discharge passage 33 in the lateral width direction X are formed so that the passage width of the discharge passage 33 increases as it approaches the discharge port 13 side from the back side of the storage chamber 37.

The pair of side wall portions 45 and the back wall portion 47 are provided as peripheral wall portions 49 surrounding the discharge passage 33 from three sides of the width direction X both sides and the back side of the discharge passage 33.

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

FIG. 7A is an enlarged side sectional view showing the discharge passage 33, and FIG. 7B shows a state in which the divided members 51 and 53 are disassembled.
Each of the dividing members 51 and 53 has a mating surface 55 facing in 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. The dividing members 51 and 53 are assembled with their mating surfaces 55 abutted against each other.

The lower split member 51 has a first passage defining portion 57 that partially defines each of the storage chamber 37, the throttle flow path 39, and the discharge port 13. The first passage defining portion 57 is formed by a lower wall surface 71 of the discharge passage 33 and a part of the inner peripheral wall surface 33b 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 thereof. The upper split member 53 also has a second passage defining portion 59 that partially defines each of the storage chamber 37, the throttle flow path 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 the region S1 from the front end side thereof to the intermediate position in the front-rear direction Y. Further, the second passage defining portion 59 is formed in a concave shape that opens downward in the region S2 from the 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 flow path 39 is defined by both the first passage defining portion 57 and the second passage defining portion 59.

When the dividing members 51, 53 are disassembled, the wall surfaces 71, 73, 33b, which are 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 split member 51 and the upper wall surface 73 of the upper split member 53 are exposed so as to face the external space 235.

As shown in FIGS. 5A and 6A, an interval holding portion 69 as a columnar body is arranged in the storage chamber 37 of the discharge passage 33. A plurality of interval holding portions 69 are arranged at intervals in the lateral width direction X.

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

FIG. 8 is a cross-sectional view taken along the line BB of FIG. The shape of the lower split member 51 described in this figure matches the cross section taken along the line CC in FIG. 5 (a).
The interval holding portion 69 rises from the lower wall surface 71 of the lower split member 51, and its upper surface contacts the upper wall surface 73 of the upper split member 53. As a result, the space holding portion 69 holds the space between the upper wall surface 73 and the lower wall surface 71 that face each other vertically in the discharge passage 33.

As shown in FIG. 3, the water discharge member 19 has a positioning structure 79 composed of a positioning recess 75 and a positioning protrusion 77. The positioning structure 79 is provided at both ends 19a in the lateral width direction of the water discharge member 19.

9 (a) is a diagram showing a part of the cross section taken along the DD line of FIG. 3, and FIG. 9 (b) shows a state in which the divided members 51 and 53 are disassembled. The shape of the lower split member 51 described in this figure matches the cross section taken along line EE in FIG. 5 (a).
The positioning recess 75 is formed as a bottomed hole that opens in the mating surface 55 of the lower dividing member 51. The positioning convex portion 77 is provided on the upper split member 53 at a position corresponding to the positioning concave portion 75, and is formed as a boss protruding from the mating surface 55 thereof.

When assembling the lower split member 51 and the upper split member 53, as shown in FIG. 9B, the operator aligns the split members 51 and 53 and positions them in the plurality of positioning recesses 75. The convex portion 77 is inserted. As a result, the divided members 51 and 53 can be easily positioned at the time of assembling, and the workability at the time of assembling is improved.

As shown in FIG. 8, the lower split member 51 is provided with a plurality of storage portions 83 for storing fixtures 81 such as screws at locations corresponding to the peripheral wall portions 49. Further, the space holding portion 69 of the lower split member 51 is also provided with a storage portion 83 for storing the fixture 81. An insertion hole 85 through which the fixture 81 is inserted is formed in each storage portion 83. The upper split member 53 is provided with a screw hole as a mounted portion 87 at a position corresponding to the insertion hole 85. The tip 81a of the fixture 81 is fastened to the attached portion 87 by screwing or the like. The dividing members 51 and 53 are detachably connected by these fixtures 81.

As shown in FIG. 9A, the storage portion 83 of the lower split member 51 includes a portion provided coaxially with the positioning recess 75. The attached portion 87 of the upper split member 53 corresponding to the insertion hole 85 of the storage portion 83 is provided in the positioning convex portion 77.

As shown in FIG. 8, the lower split member 51 and the upper split 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 on the mating surface 55 of the lower split member 51, and the first seal member 89 is arranged in the groove 91. The first seal member 89 is non-adhesively and detachably arranged in the groove 91.

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 one opening edge 13a to the other opening edge 13a in the lateral width direction of the discharge port 13. It is formed so as to extend along the peripheral wall surface 33b. The first seal member 89 is arranged so as to surround the discharge passage 33 from three sides, both sides in the width direction and the back side.

Returning to FIG. 8, a protrusion 93 is formed on the mating surface 55 of the upper split 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 sealing member 89, and the space between the plurality of mating surfaces 55 is sealed by the first sealing member 89. As a result, the first seal member 89 regulates the water in the discharge passage 33 from leaking to the outside through the mating surfaces 55. More specifically, it regulates leakage from the outer peripheral surface 19c of the water discharge member 19 through the mating surface 55 and leakage from the insertion hole 85 or the like of the storage portion 83.

An annular second seal member 95 is interposed between the tip surface 69d of the space holding portion 69 and the upper wall surface 73 of the upper split member 53 facing the tip surface 69d. Like the first seal member 89, the second seal member 95 is also non-adhesively and detachably arranged in the annular groove portion 97 formed on the tip 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 surface 69d 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 33b of the peripheral wall portion 49 of the water discharge member 19. That is, although not shown in this figure, the plurality of fixtures 81 are also arranged in the same positional relationship. These fixtures 81 are adjacent to each other in the width direction X so that the distance L2 in the width direction X both ends 19a of the water discharge member 19 is narrower than the distance L1 in the width direction X intermediate portion 19b of the water discharge member 19. Is placed in.

The operation of the water discharge device 10 according to the above embodiment will be described.
In the water discharge member 19, as shown in FIG. 4, a predetermined flow rate of water is pumped from the water supply pump 221 (see FIG. 2), and the water flows into the storage chamber 37 from the inflow port 35 through the headrace 17. , It is temporarily stored as stored water in the storage chamber 37. When water is sent from the inflow port 35 while the stored water is stored in the storage chamber 37, the stored water in the storage chamber 37 is pressurized, and the water pressure causes the stored water to be discharged through the throttle flow path 39 through the discharge port 13. The water discharge stream 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 39a of the throttle flow path 39. When the water flow passes through the storage chamber 37, the flow velocity is significantly lower than when the passage height of the discharge passage 33 is made constant, and the flow velocity is significantly reduced from the inflow port 35 to the inlet 39a of the throttle flow path 39. It is effectively rectified so that the flow velocity becomes uniform in the lateral 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 discharge member 19, each of the discharge port 13, the storage chamber 37, and the throttle flow path 39 is defined by both the upper split member 53 and the lower split member 51. Therefore, when the divided members 51 and 53 are disassembled, the inner wall surfaces 71, 73, 33b of the discharge passage 33 can be exposed to the external space 235 from the discharge port 13 to the range of the storage chamber 37. In general, when molding a part having a hollow cross section, it is more difficult to mold a part having a hollow cross section by separately molding a plurality of parts so that the inner wall surface is exposed to an external space, rather than integrally molding a single part. It becomes low, and it is easy to secure the dimensional accuracy of the inner wall surface. Therefore, according to the water discharge member 19 according to the present embodiment, it becomes easy to suppress the surface roughness of the inner wall surfaces 71, 73, 33b of the discharge passage 33, and the disorder of 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 cast surface surface unlike a metal cast product does not occur on the inner wall surfaces 71, 73, 33b of the discharge passage 33, and the surface roughness thereof can be greatly suppressed.

Further, the water flow supplied into the discharge passage 33 is likely to be turbulent due to a sudden change in the cross section of the flow path when it flows in from the inflow port 35. Further, in order to vigorously discharge the horizontally long water discharge flow W, the discharge passage 33 has a cross-sectional shape in which the passage width is wide and the passage height is low. Therefore, the water flow flowing inside the water flow also has a horizontally long and thin shape, and is easily affected by turbulent flow in the discharge passage 33, catching of foreign matter, and the like. The distance from the inflow port 35 to the discharge port 13 changes depending on the position in the width direction of the discharge port 13, and the larger the width dimension of the discharge port 13, that is, the width dimension of the discharge water flow W, the smaller the minimum distance and the maximum distance. The difference is likely to be large. Due to the above factors, when the discharge port 13 does not have a storage chamber 37, the flow velocity of the water discharge flow W discharged from the discharge port 13 tends to vary in the lateral width direction X of the discharge port 13, and the shape thereof tends to be disturbed.

In this respect, in the water discharge 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 in the storage chamber 37. It can be effectively rectified so that the flow velocity in the width direction X becomes uniform. Therefore, the water discharge flow W discharged from the discharge port 13 tends to have a uniform flow velocity in the width direction X thereof, and by suppressing the disorder of the shape, it is possible to make the water discharge flow W excellent in aesthetic appearance. Further, a more relaxing effect can be obtained by applying a spouting stream W having an excellent aesthetic appearance to the shoulder of the bather.

Further, the storage chamber 37 is formed so that each of the pair of lower wall surface 71 and the upper wall surface 73 of the discharge passage 33 facing each other expands in a direction away from the inlet 39a of the throttle flow path 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 expands in the direction in which they are separated. As a result, the water pressure of the stored water in the storage chamber 37 can be lowered, and the flow velocity thereof can be easily lowered, so that the flow velocity in the width direction X becomes uniform in the storage chamber 37, and the rectification can be performed more effectively.

Further, as shown in FIG. 8, the water discharge member 19 has the interval holding portion 69 arranged in the discharge passage 33, and thus has the following advantages. The water discharge device 10 may be used by arranging a pillow member on the upper surface of the device main body 11 and placing the head on the pillow member. In this case, a load is applied to the water discharge member 19 so as to narrow the distance between the discharge passages 33. If the interval between the discharge passages 33 is narrowed due to this load, the shape of the water discharge 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 of the discharge passage 33. In this respect, in the present embodiment, since the interval holding portion 69 can maintain the interval of the discharge passage 33, it becomes easy to suppress the disorder of the shape of the discharge water flow W even when the above-mentioned load is applied to the water discharge member 19. In particular, the divided members 51 and 53 are resin molded products whose strength is difficult to secure, but even in that case, there is a great advantage in that the interval between the discharge passages 33 due to the load can be suppressed.

At this time, if the interval holding portion 69 is arranged in the discharge passage 33, the water flow is divided by the interval holding portion 69. In this respect, the interval holding portion 69 according to the present embodiment is arranged in the storage chamber 37 in which the flow velocity of the water flow is slow and the distance to the discharge port 13 is farther than the throttle flow path 39. Therefore, even if the water flow is divided by the interval holding portion 69, it is easy for the divided water flow to merge at an early stage before reaching the discharge port 13, and it is easy to suppress the disturbance of the shape of the discharge water flow W due to the division of the water flow. Become.

Further, if the first seal member 89 is attached to the upper split member 53 without adhesion, it can be easily removed when the split members 51 and 53 are assembled, and if the first seal member 89 is attached by adhesive, the assembly work becomes troublesome. 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, the assembling work becomes more troublesome if it is attached to the upper split member 53 by adhesive. In this regard, since the first seal member 89 according to the present embodiment is arranged in the groove 91 of the lower division member 51, the first seal member 89 is divided upward while being placed in the groove 91 without adhesion. The member 53 can be assembled to the lower split member 51, and the 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, as shown in FIG. 5, the water discharge member 19 has a depth dimension smaller than the width dimension in order to reduce the occupied space while discharging the water discharge stream W having a wide width. Therefore, the distance from the force point to which the bending force is applied, that is, the distance from the force point to the point of action tends to be longer in both ends 19a than in the width direction X intermediate part 19b of the water discharge member 19, and a correspondingly larger bending moment acts. Easy to do. In this respect, in the present embodiment, the plurality of fixtures 81 (not shown in this figure) are arranged so that the distance L2 at both end portions 19a is narrower than the distance L1 at the intermediate portion 19b of the water discharge member 19. , The degree of fixation at both end portions 19a is higher than that of the intermediate portion 19b. Therefore, in the intermediate portion 19b of the water discharge member 19, the interval L1 of the fixtures 81 is widened to suppress the number thereof, and at both end portions 19a, the interval L2 of the fixtures 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 dividing members 51 and 53 is a resin molded product, it is possible to provide a water discharge device 10 having various color variations by mixing a coloring agent with the 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.
