JP-A 63-247433 No. 7-54362 Japanese Patent No. 4154733

  Since the water outlet for performing waterfall-like water discharge is formed in an elongated shape, the difference in flow velocity between the center and both ends of the water outlet becomes large. For this reason, there has been a problem that after water discharge from the water discharge port, it gradually converges so as to squeeze toward the center side. From the viewpoint of aesthetics, the waterfall-like water discharge is preferably as long as possible until it converges. In this respect, in any of the spouts disclosed in Patent Documents 1, 2, and 3, the flow velocity distribution cannot be made uniform enough to make the distance to converge while maintaining a uniform width. There was room for improvement in terms of increasing the convergence distance of the waterfall.

  An object of this invention is to provide the water discharging apparatus which can implement | achieve waterfall-like water discharging with a long distance until it converges.

  (1) In order to achieve the above object, the present invention provides a water discharge device (for example, described later) including a water discharge portion (for example, a water discharge plate 20 described later) in which an elongated water discharge port (for example, a water discharge port 21 described later) is formed. In the water discharge device 1), the water discharge port is continuous as the opposite long side portions (for example, long side portions 31 and 32 described later) approach the both end sides from the center side in the longitudinal direction of the water discharge port. Provided is a water discharging device formed so as to be separated from each other in a stepwise manner.

  As a result, the long sides facing each other are formed so as to be separated from each other as they approach both ends, so that it is possible to effectively prevent the waterfall-shaped water discharge from being biased in the longitudinal direction, and the flow velocity distribution in the longitudinal direction is substantially uniform. It is possible to realize waterfall water discharge with a long distance until convergence.

  (2) The long side portion facing the water discharge port is parallel to the longitudinal direction, and is an imaginary straight line passing through the center of the short side portion (for example, short side portions 35 and 36 described later) of the water discharge port. It is preferably formed so as to have a line-symmetrical relationship with an axis of symmetry (for example, a virtual line L described later).

  Thereby, the unevenness of the flow velocity distribution of the water discharge port can be eliminated over the entire water discharge port, and a more uniform width can be prepared, and a straight waterfall water discharge parallel to the longitudinal direction can be realized.

  (3) The long side portion facing the spout is formed at the center in the longitudinal direction, and is a linear straight portion (for example, straight portions 311 and 321 described later) parallel to the longitudinal direction, and the straight portion. It is preferable to have slope portions (for example, slope portions 312 and 322, which will be described later) that are formed on both sides of the water and are inclined so as to be separated from each other as they approach both ends of the water discharge port in the longitudinal direction.

  As a result, the force to make the long side portions facing each other come into contact with the outside by an O-ring (for example, an O-ring 18 described later) or the like that seals the outer peripheral portion of the water discharge port while making the flow velocity distribution uniform by the inclined portion. Even if it works, the rigidity of the water discharging part is ensured by the straight part formed at the center of the long side part, so that the deformation of the long side part can be prevented.

  (4) The long side portions (for example, long side portions 431 and 432 to be described later) that face the water discharge port (for example, a water discharge port 421 to be described later) are arranged in the central portion (for example, a center portion 439 to be described later) in the longitudinal direction. , 440) to both ends of the water discharge port, inclined portions (for example, inclined portions 441 and 442 described later) that are continuously inclined are formed, and the water discharge portion (water discharge plate 420 described later) A rib that is disposed between the central portion of the long side portion and the central portion of the long side portion on the other side, and at least a shape that faces the water discharge direction is tapered toward the water discharge direction (for example, It is preferable to include a rib 425) described later.

  Thereby, the ratio of the inclined part in a long side part can be enlarged, and even if it is a case where the difference of the flow velocity of a center and both ends is large, uniform shaped waterfall-like water discharge is realizable. Further, even when a force to contact the long side portions facing each other works from the outside, the ribs formed in the central portion where the long side portions facing each other are closest may prevent the long side portions from contacting each other. It is possible to prevent a situation in which the long-side portions come into contact with each other and the waterfall-like water discharge is divided. Furthermore, since the rib is tapered toward the water discharge direction, it is possible to prevent a situation where the waterfall water discharge is divided by the rib.

  (5) The water discharge portion is disposed such that the long side portion on the other side is at a low position with respect to the long side portion on one side of the water discharge port, and the long side portion on the other side is disposed along the long side portion on the other side. It is preferable to provide an elongated bulging portion (for example, a bulging portion 22 described later) outside the water outlet.

  Thereby, when the water discharge of the water discharge device is stopped, the movement of the water that tries to move from the water discharge port to the lower position through the surface of the water discharge portion can be regulated by the bulging portion, and the lower surface of the main body of the water discharge device The dripping of water can be effectively prevented.

  (6) It is preferable that the water outlet has a short side portion (for example, short side portions 35 and 36 described later) formed in an arc shape.

  Accordingly, it is possible to effectively prevent a situation in which water scatters at both ends of the water discharge port and the shapes of both ends of the waterfall water discharge collapse, and a wide waterfall water discharge can be obtained.

  According to the water discharge device of the present invention, waterfall-like water discharge having a long distance until convergence can be realized.

  Hereinafter, preferred embodiments of the water discharge device of the present invention will be described with reference to the drawings. Drawing 1 is a perspective view showing signs that water discharging apparatus 1 of a 1st embodiment was seen from the undersurface side. FIG. 2 is a side view showing a state in which the water discharge device 1 is attached to a wall. FIG. 3 is a plan view schematically showing the inside of the main body 10 of the water discharge device 1. In the following description, the water discharge direction is the direction in which water flows, and the upstream and downstream directions in the direction in which water flows refer to the upstream and downstream directions unless otherwise specified.

  First, the whole structure of the water discharging apparatus 1 which concerns on 1st Embodiment is demonstrated. As shown in FIG. 1, the water discharge device 1 includes a main body 10, a switching handle 11, a temperature adjustment handle 12, and a water discharge plate 20.

  The main body 10 is connected to a back surface of a pipe to which hot water is supplied from the outside and a pipe to which water is supplied. The main body 10 of the present embodiment includes pipe covers 13 and 14 that cover the pipes to be connected on the back surface thereof. The piping is connected to the main body 10 through the internal space of the piping covers 13 and 14. As shown in FIG. 2, in this embodiment, the water discharging apparatus 1 is attached to walls, such as a bathroom, in the form by which the main body 10 is supported by a wall surface via piping. A tube 5 for supplying hot water to a shower section (not shown) is connected between the pipe cover 13 and the pipe cover 14 on the back surface of the main body 10.

  As shown in FIG. 3, a flow path 17 is formed inside the main body 10 for mixing hot water sent through a pipe and discharging water from a water outlet 21 described later. The flow path 17 shown with a broken line in FIG. 3 shows the one part. In this embodiment, the flow path 17 of the main body 10 is formed so that hot water can be supplied to the above-described shower part via the tube 5.

  The switching handle 11 is for switching the water supply destination to either the water outlet 21 or the shower part of the water discharging device 1, and is disposed on one side surface of the main body 10. A user of the water discharge device 1 uses the switching handle 11 to stop the hot water and adjust the amount of water discharged.

  The temperature adjustment handle 12 adjusts the temperature of the hot water discharged, and is disposed on the side surface of the main body 10 opposite to the surface on which the switching handle 11 is disposed. The water discharge device 1 of the present embodiment is a mixing faucet that allows the user to adjust the temperature of hot water according to the intended use. For example, an appropriate system such as a thermostat mixing faucet type is adopted.

  As shown in FIG. 1, the water discharge plate 20 is formed to have an elongated water discharge port 21 and is attached to the lower surface of the main body 10. The water discharge plate 20 is disposed at the end of the flow path 17 of the main body 10, and the hot water supplied to the main body 10 through the pipe is shaped into a waterfall shape by the water discharge port 21. The detailed configuration of the water discharge plate 20 will be described later.

  Next, the internal structure of the main body 10 of the water discharge device 1 will be described. The water discharge device 1 of the first embodiment is configured to include a buffer chamber 19 inside the main body 10. As shown in FIG. 3, the buffer chamber 19 is formed in a room shape inside the main body 10, and is disposed on the flow path 17 inside the main body 10 and upstream of the water discharge plate 20.

  Inside the buffer chamber 19, a plurality of buffer members 191 formed in a columnar shape are arranged in a staggered manner. The plurality of buffer members 191 are all arranged in the vertical direction of the buffer chamber 19 so that the axial direction thereof is parallel to the gravity direction, and connects the ceiling surface and the floor surface of the buffer chamber 19. Hot water sent from the pipe passes through the buffer chamber 19 and is discharged from the water outlet 21 of the water discharge plate 20 to the outside. Since the buffer member 191 is arranged in the vertical direction perpendicular to the direction in which the hot water flows, the hot water entering the buffer chamber 19 collides with the buffer member 191, and the momentum is reduced and the flow is adjusted. Thus, the water discharge plate 20 is sent downstream. Thus, the water discharging apparatus 1 of this embodiment is comprised so that the buffer member 191 for loosening the flow rate of the hot water sent from piping may be further provided.

  Next, a detailed configuration of the water discharge plate 20 will be described. FIG. 4 is an enlarged view showing a state of the water discharge plate 20 attached to the main body 10 of the water discharge device 1. FIG. 5 is an enlarged view schematically showing the state of the end portion of the water discharge port 21 of the water discharge plate 20. In FIG. 5, one side of the end portion of the water discharge port 21 is expressed in an enlarged manner, and the other end portion is omitted because it has the same structure as the enlarged end portion. FIG. 6 is an enlarged side view showing a state of the water discharge plate 20 attached to the main body 10 of the water discharge device 1.

  As shown in FIG. 4, the water discharge plate 20 is fixed to the lower surface of the main body 10 of the water discharge device 1 via a fastening member such as a screw 60. As shown in FIGS. 4, 5, and 6, the water discharge plate 20 of the first embodiment includes a plate body 30, a water discharge port 21, a bulging portion 22, an annular portion 23, a rectifying network 24, and a recess. 51. Hereinafter, each structure with which the water discharging plate 20 is provided is demonstrated.

  The plate body 30 is formed in an elongated plate shape. The water discharge port 21 is formed at the center of the plane portion of the plate body 30.

  The water discharge port 21 is formed in the plate body 30 as an elongated opening surrounded by long side portions 31 and 32 facing each other and short side portions 35 and 36 facing each other. As shown in FIG. 4, the short side portions 35 and 36 are both formed in an arc shape.

  The long side portion 31 on one side includes a straight portion 311 and inclined portions 312 disposed on both sides of the straight portion 311. The long side portion 32 on the other side includes a straight portion 321 and inclined portions 322 arranged on both sides of the straight portion 321. The straight portions 311 and 321 are each formed in a substantially linear shape at the center of the long side portions 31 and 32 so as to be substantially parallel to the longitudinal direction of the water discharge port 21. The inclined portions 312 and 322 facing each other have a divergent shape that is separated from each other as it approaches the both end sides from the center side. In the following description, the long side portion 31 on one side simply means the long side portion 31 located on the distal end side of the main body 10 with the water discharge plate 20 attached. Similarly, the long side portion 32 on the other side means the long side portion 32 located on the base end side of the main body 10 (see FIG. 4).

  As shown in FIG. 5, the shape of the water discharge port 21 will be described using a straight line that is parallel to the longitudinal direction of the water discharge port 21 and passes through the centers of the short side portions 35 and 36 as a virtual straight line L. In the direction orthogonal to the virtual straight line L, the distance from the virtual straight line L to the long side portion 31 or the long side portion 32 is a distance d. The inclined portions 312 and 322 of the long side portions 31 and 32 are formed so that the distance d continuously increases from the center side toward both end sides. Therefore, the distance d1 on the center side and the distance d2 on both ends satisfy the relationship d2> d1. Further, the inclined portions 312 and 322 are set so that the increments of the distance d at the facing portions thereof are equal. Thus, the long side portions 31 and 32 facing each other in the present embodiment have a line-symmetric relationship with the virtual straight line L as the symmetry axis.

  In addition, it can be said that when the water discharge port 21 of the present embodiment is divided into two regions by the virtual straight line L, the areas of the two regions arranged in the short direction are equal. More specifically, a region surrounded by the virtual straight line L, the long side portion 31, and the short side portions 35 and 36 is defined as a one-side region Z1. Similarly, a region surrounded by the virtual straight line L, the long side portion 32 and the short side portions 35 and 36 is defined as another region Z2 as another region. The opening portion of the water discharge port 21 of the present embodiment includes the one side region Z1 and the other side region Z2, and the area of the one side region Z1 is equal to the area of the other side region Z2. I can say that.

  The bulging portion 22 will be described. As shown in FIG. 4, the bulging portion 22 is formed as an elongated rib along the long side portion 32 on the other side of the water discharge port 21. As shown in FIG. 6, the bulging portion 22 bulges from the planar portion of the plate main body 30 in the thickness direction of the plate main body 30. In the side view of FIG. 6, the bulging portion 22 has a substantially triangular shape with a cross-sectional shape facing downward, and is formed in an arc shape in which the hypotenuse portion on the water discharge port 21 side is curved inward.

  As shown in the side view of FIG. 2, the lower surface of the main body 10 is formed so as to be inclined downward as it approaches the wall side (base end side) from the distal end side. As shown in FIG. 6, when the water discharge plate 20 is attached to the main body 10, the wall side of the plate main body 30 is inclined downward, and the other side of the long side portion 31 on one side of the water discharge port 21 is inclined. The long side portion 32 is in a low position. If the water discharge of the water discharge device 1 is stopped in this state, water droplets leaking from the water discharge port 21 may try to move to the wall side of the main body 10 through the surface of the plate main body 30. Even in such a case, the movement of the water droplet is restricted by the bulging portion 22 formed along the long side portion 32 on the other side, and the situation where the water droplet drips from the lower surface of the main body 10 on the wall side can be prevented.

  The annular portion 23 will be described. As shown in FIG. 6, the annular portion 23 is disposed on the surface of the plate body 30 opposite to the surface on which the bulging portion 22 is formed. The annular portion 23 is formed in a cylindrical shape that is slightly larger than the water discharge port 21, and its cross-sectional shape is an elongated ellipse. The internal space of the annular portion 23 communicates with the water discharge port 21, and the hot water sent from the flow path 17 of the main body 10 reaches the water discharge port 21 through the annular portion 23.

  A mounting groove 40 to which the O-ring 18 as a sealing member is attached is formed in the annular portion 23 over the entire outer peripheral surface thereof. The water discharge plate 20 is fixed to the main body 10 with the O-ring 18 attached to the attachment groove 40.

  The rectifying network 24 will be described. As shown in FIG. 4, the rectifying network 24 is for rectifying hot water flowing from the water outlet 21, and is supported on the inner peripheral surface of the annular portion 23 so as to cover the water outlet 21. The rectifying network 24 of this embodiment is inserted so as to be incorporated into the annular portion 23 when the water discharge plate 20 is molded, and is an integral member with the annular portion 23.

  The concave portion 51 is a portion where a screw 60 is fastened to fix the water discharge plate 20 to the main body 10, and is formed in a concave shape in a planar portion of the plate main body 30. As shown in FIG. 4, in the present embodiment, two recesses 51 are arranged on both sides of the water discharge port 21. As shown in FIG. 6, in a state where the water discharge plate 20 is attached to the main body 10 with screws 60, the flat portion of the plate main body 30 and the lower surface of the main body 10 are attached without a gap so as to be substantially in the same plane.

  Next, operation | movement of the water discharging apparatus 1 is demonstrated. When the user operates the switching handle 11 of the water discharging device 1 so as to discharge water, the hot water sent via the pipe is sent to the buffer chamber 19 on the flow path 17 of the main body 10. With the buffer member 191 in the buffer chamber 19, the momentum of the hot water is reduced and the flow is adjusted and sent to the water discharge plate 20 side. The hot water sent to the water discharge plate 20 is shaped into a waterfall by the water discharge port 21 and discharged. Thus, in this embodiment, since the flow of hot water is sufficiently reduced by the buffer chamber 19 disposed in the flow path 17 of the main body 10 and the flow is adjusted, hot water is sent to the water discharge plate 20, Waterfall water discharge with a more uniform width is possible.

According to the water discharging apparatus 1 of 1st Embodiment demonstrated above, there exist the following effects.
The water discharge device 1 of the first embodiment includes a water discharge plate 20 in which an elongated water discharge port 21 is formed. The water discharge port 21 has long side portions 31 and 32 facing each other in the center in the longitudinal direction of the water discharge port 21. It forms so that it may mutually leave | separate continuously or in steps as it approaches both ends from the side. Thereby, since the long side parts 31 and 32 which face each other are formed so as to be separated from each other as they approach both end sides, it is possible to effectively suppress the waterfall-like water discharge from being biased in the longitudinal direction, and the flow velocity distribution in the longitudinal direction is substantially reduced. It can be made uniform, and waterfall-like water discharge with a long distance to converge can be realized.

  The long side portions 31 and 32 facing the water discharge port 21 are parallel to the longitudinal direction and have a line-symmetric relationship with a virtual straight line L passing through the center of the short side portions 35 and 36 of the water discharge port 21 as the axis of symmetry. Formed. Thereby, the deviation of the flow velocity distribution of the spout 21 can be eliminated over the whole spout 21, and waterfall-shaped spout with a more uniform width can be realized.

  The long side portions 31 and 32 facing the water discharge port 21 are formed at the center in the longitudinal direction, are formed on the linear straight portions 311 and 321 parallel to the longitudinal direction, and on both sides of the linear portions 311 and 321, in the longitudinal direction. And inclined portions 312 and 322 that are inclined so as to be separated from each other as they approach the both ends of the water discharge port 21. Thereby, while making the flow velocity distribution uniform by the inclined portions 312 and 322, the force to contact the long side portions 31 and 32 facing each other by the O-ring 18 that seals the outer peripheral portion of the water discharge port 21 is externally applied. Even in the case of working, since the rigidity of the long side portions 31 and 32 of the water discharge plate 20 is ensured by the straight portions 311 and 321 formed at the center of the long side portions 31 and 32, the long side portions 31 and 32 are secured. Can be prevented from being deformed.

  The water discharge plate 20 is disposed so that the long side portion 32 on the other side is lower than the long side portion 31 on one side of the water discharge port 21, and the outside of the water discharge port 21 along the long side portion 32. Is provided with an elongated bulging portion 22. Thereby, when the water discharge of the water discharging apparatus 1 is stopped, the movement of the water that tries to move from the water discharge port 21 to the lower position through the surface of the water discharge plate 20 can be regulated by the bulging portion 22. The dripping of water on the lower surface of the main body 10 of the apparatus 1 can be effectively prevented.

  The water discharge port 21 has short side portions 35 and 36 formed in an arc shape. Accordingly, it is possible to effectively prevent a situation where water is scattered at both ends of the water discharge port 21 and the shapes of both ends of the waterfall water discharge collapse, and a wide waterfall water discharge can be obtained.

  Next, the water discharging apparatus 1 which concerns on 2nd Embodiment is demonstrated. FIG. 7 is a plan view showing a state of the water discharge plate 420 of the second embodiment. 8 is a cross-sectional view taken along line AA in FIG. 9 is a cross-sectional view taken along the line BB in FIG. The water discharging apparatus 1 of 2nd Embodiment uses the water discharging plate 420 of a structure different from the water discharging plate 20 of 1st Embodiment. In addition, the same code | symbol is attached | subjected to the structure similar to the said embodiment, and the description is abbreviate | omitted.

  As shown in FIGS. 7, 8 and 9, the water discharge plate 420 used in the second embodiment includes a plate body 430, a water discharge port 421, a rib 425, a bulging portion 22, an annular portion 23, A rectifying network 24 and a recess 51 are provided. The water discharge plate 420 of the second embodiment is different from the water discharge plate 20 of the first embodiment in that the shape of the water discharge port 421 formed in the plate main body 430 is different and a rib 425 is further provided.

  The water outlet 421 of 2nd Embodiment is demonstrated. The water discharge port 421 is formed in the plane portion of the plate body 430 as an elongated opening surrounded by the long side portions 431 and 432 facing each other and the short side portions 35 and 36 facing each other. As in the first embodiment, the short side portions 35 and 36 are both formed in an arc shape.

  The long side portion 431 on one side has inclined portions 441 extending from the central portion 439 to both sides. The other long side portion 432 has inclined portions 442 extending from the central portion 440 to both sides. The inclined portions 441 and 442 facing each other are inclined substantially linearly so as to be separated from each other as approaching both end sides. In the second embodiment, most of the long side portions 431 and 432 facing each other are inclined portions 441 and 442, and are formed so as to be continuously separated from each other over the entire area. Also in the second embodiment, when a virtual straight line L similar to that of the first embodiment is considered, the long side portions 431 and 432 facing each other have a line-symmetrical relationship with the virtual straight line L as an axis of symmetry.

  The rib 425 will be described. As shown in FIG. 8, the rib 425 is disposed inside the annular portion 23 and on the downstream side of the rectifying network 24 in the water discharge plate 20. The rib 425 of the present embodiment is formed in a triangular shape whose cross-sectional shape has an acute angle on the downstream side in the water discharge direction. As shown in FIG. 9, the rib 425 is disposed at the center of the water discharge port 421 so as to connect the central portions 439 and 440 of the long side portions 431 and 432, and the cross-sectional shape thereof is rectangular when viewed from the side. Yes.

According to the water discharging apparatus 1 of 2nd Embodiment demonstrated above, there exist the following effects.
That is, in the water discharge device 1 of the second embodiment, the long side portions 431 and 432 facing the water discharge port 421 are continuously inclined in the longitudinal direction so as to be separated from each other from the center portions 439 and 440 to both ends of the water discharge port 421. Inclined portions 441 and 442 are formed, and the water discharge plate 420 is disposed between the central portion 439 of the long side portion 431 on one side and the central portion 440 of the long side portion 432 on the other side, and faces at least the water discharge direction. It is comprised so that the shape may be provided with the rib 425 formed in a taper shape toward the water discharge direction. Thereby, the ratio of the inclined parts 441 and 442 in the long side portions 431 and 432 can be increased, and even when the difference between the flow rates at the center and both ends is large, the waterfall water discharge having a uniform shape can be obtained. realizable. Further, even when a force to contact the long side portions 431 and 432 facing each other works from the outside, the ribs 425 formed in the central portions 439 and 440 where the long side portions 431 and 432 facing each other are closest to each other, It is possible to prevent a situation in which the contact between the long side portions 431 and 432 is hindered and the long side portions 431 and 432 are in contact with each other and the waterfall-like water discharge is divided. Furthermore, since the rib 425 is formed in a tapered shape toward the water discharge direction, it is possible to prevent a situation where the waterfall water discharge is divided by the rib 425.

  The preferred embodiments of the water discharge device of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and can be modified as appropriate. The shape of the water outlet of the above embodiment can be changed as follows. For example, the long side portions facing each other can be separated from each other in a stepped manner. Further, the long side portions facing each other can be formed so as to be asymmetrically separated from each other. For example, in the case of having a straight part and an inclined part like the water outlet of the first embodiment, the starting position of the inclined part formed on the long side part facing each other is an asymmetrical shape shifted to one side in the longitudinal direction. It can also be changed.

  The shape of the rib 425 of the second embodiment can be changed as appropriate. For example, in the second embodiment, the tip on the downstream side in the water discharge direction is tapered, but the tip on the upstream side can also be tapered.

  The rectifying network 24 of the above embodiment is an integral part of the water discharging plate 20 by being inserted when the water discharging plate 20 is molded, but the method of attaching the rectifying network 24 to the water discharging plate 20 should be changed as appropriate. Can do. Next, with reference to FIG. 10, the water discharge plate 520 of 3rd Embodiment is demonstrated. The water discharge plate 520 of the third embodiment is different from the water discharge plate 420 of the second embodiment in the method of attaching the rectifying network 24 to the water discharge plate 520 and the configuration related thereto. FIG. 10 is a cross-sectional view of the water discharge plate 520 of the third embodiment. FIG. 10 corresponds to FIG. 9 (cross-sectional view taken along line BB in FIG. 7) described in the second embodiment. As shown in FIG. 10, in the water discharge plate 520 of the third embodiment, a slit 521 for inserting the rectifying network 24 is formed in the annular portion 23. The slit 521 is formed when the water discharge plate 520 is molded. The rectifying network 24 is fixed to the water discharge plate 520 by being inserted from the slit 521 after the water discharge plate 520 is molded. By adopting this method, the molding process can be simplified.

  In the above embodiment, the water discharge ports 21 and 421 are formed on the water discharge plates 20, 420 and 520, but this configuration can be changed as appropriate. For example, in the said embodiment, although the water discharging plate 20,420,520 is attached to the main body 10 as another member, this invention is applicable also to the structure by which a water discharge port is formed in the main body of a water discharging apparatus. That is, it can be set as the structure which forms a water discharge port in the water discharging apparatus 1 itself in which a water discharging part and a main body are integrally formed.

  In the above embodiment, the bulging portion 22 is configured along the long side portion 32 located on the wall side (base end side) in a state of being attached to the main body 10, but is limited to this configuration. However, any configuration may be used as long as it is formed along a long side portion at a low position. For example, in the case of a configuration in which the lower surface of the main body is inclined upward as it approaches the proximal side (wall side) from the distal end side, the long side portion on the distal end side is positioned lower than the long side portion on the proximal end side. The bulging portion may be formed along the long side portion on the distal end side.

  As described in the above embodiment, the present invention is not limited to the water discharge device 1 of the type attached to the wall surface of the bathroom, and can be applied to various water discharge devices.
