Then, the faucet device 100 can be obtained by attaching the cover member 140 to the water discharge structure 1 and combining it with the upstream water conduit 110, the faucet mechanism 120, and the water purifying unit 130.

In the water discharge structure 1 described above, the upstream member 30 and the water discharge port forming member 60 are rotatably held by the stopper 70. Further, in the water discharge structure 1, the shower forming member 40 and the water discharge port forming member 60 are fitted and operate integrally.

The fitting between the shower forming member 40 and the spout forming member 60 will be described with reference to FIGS. 7 to 9. FIG. 7 is a cross-sectional view (cross-sectional view corresponding to the line VII-VII in FIG. 2) in a state where the shower forming member 40 and the water spout forming member 60 are fitted together. FIG. 8 is a partially cutaway perspective view of the shower forming member 40 and the water spout forming member 60 fitted together. FIG. 9 is a bottom view in a state where the shower forming member 40 and the water spout forming member 60 are fitted to each other.

As shown in FIG. 7, the shower forming member 40 and the water spout forming member 60 spout into a plurality of vertically extending grooves 42 a formed on the inner peripheral surface of the inner tubular portion 42 of the shower forming member 40. A plurality of vertically extending projections 63a formed on the outer peripheral surface of the inner tubular portion 63 of the water port forming member 60 are fitted. Therefore, when the water outlet forming member 60 is rotated with respect to the upstream member 30 about the rotation center that coincides with the central axis CL1 of the joint member 10, the water outlet forming member 60 follows the rotation. Thus, the shower forming member 40 is also rotatable.

Further, as shown in FIGS. 8 and 9, in a state where the shower forming member 40 and the water outlet forming member 60 are fitted together, it corresponds to the opening 62 a provided in the water outlet forming portion 62 of the water outlet forming member 60. The boss forming portion 44 that configures the connecting portion 43 of the shower forming member 40 is disposed at the position (upper side). Therefore, as shown in FIG. 9, the ribs 62b included in the water outlet forming portion 62 of the water outlet forming member 60 and the boss forming portions 44 of the shower forming member 40 are alternately arranged along the circumference. It will be in the state of being.

As described above, with the shower forming member 40 and the spout forming member 60 fitted together, with respect to the upstream side member 30 with the rotation center that coincides with the central axis CL1 of the joint member 10 as the axis. When the water discharge port forming member 60 is rotated by this, the shower formation member 40 is rotated together with the water discharge port forming member 60 with the rotation center as an axis. Since the O-ring R1 is interposed between the upstream member 30 and the water outlet forming member 60, the water outlet forming member 60 can be smoothly rotated.

The shower forming member 40 has an axis of rotation about the center of rotation with the female screw 41a provided on the inner peripheral surface of the mounting portion 41 assembled with the male screw 33a provided on the outer peripheral surface of the surrounding wall portion 33 of the upstream side member 30. Rotate as a heart. By this rotation, the shower forming member 40 moves in the up-down direction to move the shower forming member 40 relative to the water outlet forming member 60 along the water discharge direction (extending direction of the outer cylinder portion 61 of the water outlet forming member 60). It can be changed. Further, with the rotation, the shower forming member 40 moves in the vertical direction. In the water discharge structure 1 shown in FIG. 2, when the water discharge port forming member 60 is rotated with respect to the upstream side member 30 in a predetermined direction, the shower forming member 40 is connected to the upstream side by combining the female screw 41a and the male screw 33a. It moves in a direction away from the side member 30. As a result, as shown in FIG. 10, the boss 44b of the boss forming portion 44 that constitutes the connecting portion 43 of the shower forming member 40 is provided with respect to the opening 62a provided in the water outlet forming portion 62 of the water outlet forming member 60. It is possible to move to the state of entering. Further, in the water discharge structure 1 shown in FIG. 10, when the water discharge port forming member 60 is rotated with respect to the upstream side member 30 in a direction opposite to the above predetermined direction, the shower forming member 40 becomes the above-mentioned female screw 41a. By assembling the male screw 33a with the male screw 33a, it is possible to move in a direction approaching the upstream member 30 and shift to the state shown in FIG.

The water discharge structure 1 in the water faucet device 100 according to the present embodiment can switch between the straight water discharge and the shower water discharge by switching between the state shown in FIG. 2 and the state shown in FIG. 10.

In the state shown in FIG. 2, the water discharge from the water discharge structure 1 is straight. Specifically, the water introduced from the guide tube portion 14 of the joint member 10 into the main body portion 32 of the upstream side member 30 along the water discharge direction DR1 passes through the recess 37 to the through hole 37b provided in the bottom plate 37a. After that, it moves to the concave portion 38 side. Here, in the recess 38, as shown in FIG. 2, the annular protruding portion 39 formed on the bottom plate 37 a of the upstream member 30 is different from the step portion 42 b of the inner tubular portion 42 of the shower forming member 40. It is in contact with the attached annular inner plug member 50. Therefore, the water flowing into the recess 38 does not move to the outside of the protrusion 39 and the inner plug member 50, but moves downward along the inner peripheral surface of the inner tubular portion 42 of the shower forming member 40. As a result, the liquid is discharged downward from the straight water discharge port OP1 on the inner peripheral surface side of the center port forming member 80. Since the water discharged from the straight water discharge port OP1 gathers together and flows downward, the water discharge is straight. That is, a flow path for straight water discharge from the upstream side to the straight water discharge port OP1 is formed.

On the other hand, in the state shown in FIG. 10, the water spouted from the water spouting structure 1 has a shower shape. Specifically, the water introduced from the guide tube portion 14 of the joint member 10 into the main body portion 32 of the upstream side member 30 along the water discharge direction DR1 passes through the recess 37 to the through hole 37b provided in the bottom plate 37a. After that, it moves to the concave portion 38 side. Up to this point, the state is the same as that shown in FIG.

Here, in the recess 38, as shown in FIG. 10, with respect to the annular protrusion 39 formed on the bottom plate 37 a of the upstream member 30 and the step portion 42 b of the inner tubular portion 42 of the shower forming member 40. It is separated from the attached annular inner plug member 50. This is because the shower forming member 40 has moved downward with respect to the upstream member 30. Therefore, part of the water that has flowed into the recess 38 moves to the outside of the protrusion 39 and the inner plug member 50, and the inner peripheral surface of the surrounding wall 33 of the upstream member 30 and the shower forming member 40. It moves downward between the outer peripheral surface of the inner tubular portion 42. The water that has moved below the surrounding wall portion of the upstream member 30 also moves downward along the inner peripheral surface of the outer tubular portion 61 of the water spout formation member 60. In the state shown in FIG. 10, as described above, in the water outlet forming portion 62 at the lower end of the water outlet forming member 60, the shower formation is performed with respect to the opening 62 a provided in the water outlet forming portion 62 of the water outlet forming member 60. The boss 44b of the boss forming portion 44 forming the connecting portion 43 of the member 40 is inserted. As a result, as shown in FIG. 9, an opening penetrating the shower forming member 40 and the spout forming member 60 is formed at a position where the opening 62a of the spout forming portion 62 and the through hole 44a of the boss forming portion 44 overlap each other. To be done. This opening becomes the shower water discharge hole OP2.

In the state shown in FIG. 10, the boss 44b of the boss forming portion 44 forming the connecting portion 43 of the shower forming member 40 is inserted into the opening 62a provided in the water outlet forming portion 62 of the water outlet forming member 60. , A plurality of shower water discharge holes OP2 are formed. The water that has moved to the outside of the protrusion 39 and the inner plug member 50 is discharged downward from the shower water discharge port OP2. The water discharged from the plurality of shower water discharge holes OP2 individually flows downward, so that the water discharge becomes a shower shape. That is, a flow path for shower water discharge from the upstream side to the shower water discharge hole OP2 is formed.

The size of the water discharged from the shower water discharge port OP2 is controlled by the size of the region where the opening 62a of the water discharge port forming portion 62 and the through hole 44a of the boss forming portion 44 overlap. That is, the size of the opening penetrating the shower forming member 40 and the water spout forming member 60 formed by the overlapping of the opening 62a of the water spout forming portion 62 and the through hole 44a of the boss forming portion 44 is reduced. By designing the arrangement of the holes 44a and the openings 62a, the diameter of the water discharged from each shower water discharge hole OP2 (the size of the water flow) can be reduced.

In addition, the length of the shower water discharge hole OP2 along the water discharge direction DR1 can control the degree of splashing of water discharged from the shower water discharge hole OP2. That is, when the shower water discharge hole OP2 is formed by increasing the thickness of the opening 62a and the length of the boss 44b that enters the opening 62a (the length of the boss 44b along the vertical direction), the shower water discharge hole OP2 is discharged. It is possible to more finely control the discharge direction of the sprayed water and reduce the degree of splashing. However, the shower water discharge hole OP2 suitable for shower water discharge can be formed by setting at least a part of the boss 44b into the opening 62a.

Even in the state shown in FIG. 10, there is water flowing inward of the protrusion 39 and the inner plug member 50. As in the state shown in FIG. 2, the water flowing inward is discharged downward from the straight water outlet OP1 on the inner peripheral surface side of the central opening forming member 80, so that the water is straightened. That is, in the state shown in FIG. 10, there are both a straight water discharge discharged from the straight water discharge port OP1 and a shower water discharge formed by discharging from the plurality of shower water discharge holes OP2. The shower water discharge port OP2 is arranged in an annular shape so as to surround the straight water discharge port OP1, and the water discharged from the shower water discharge port OP2 is easily scattered outward. As shown in FIG. 10, even in the state where water is discharged from both the straight water discharge port OP1 and the shower water discharge hole OP2, it is assumed in the present embodiment that the water discharged from the water discharge structure 1 has a shower shape. That is, a state where at least shower-like water is discharged from the shower water discharge port OP2 is referred to as a shower water discharge state.

In the water discharge structure 1 of the water faucet device 100 according to the present embodiment, when the shower water discharge is switched from the straight water discharge to the shower water discharge, the shower forming member 40 moves in the vertical direction as described above, so that the vicinity of the shower water discharge hole OP2. The shape of the opening changes. Therefore, when foreign matter is mixed in the path from the guide tube portion 14 of the upstream joint member 10 to the shower water discharge hole OP2, the shower water discharge hole OP2 is removed by using the water moving in the flow path toward the shower water discharge hole OP2. It is possible to pass through the opening 62a of the water discharge port forming portion 62 to be formed and the through hole 44a of the boss forming portion 44 and discharge it to the outside of the system.

In a conventional faucet device including a water discharge structure for performing shower water discharge, shower-like water is discharged by passing water through a sprinkler plate having a plurality of through holes having a predetermined diameter and discharging the water to the outside. To do. The diameter of the through hole of the water sprinkling plate is often designed to be small to some extent in accordance with the size of the water discharged in the shower, which easily causes clogging. Further, when foreign matter such as scale is mixed in the water flowing through the conventional water discharge structure, there is a high possibility that the through holes of the water spray plate will be clogged. In order to return the clogged water spray plate to its original state, it is necessary to remove the clogged through hole or the foreign matter upstream thereof by some method. However, in the conventional water discharge structure, in order to recover from the clogging, it is necessary to separately perform an operation for removing the foreign matter. As described above, in the conventional water discharge structure, it has been required to perform work for maintenance against clogging.

On the other hand, in the water discharge structure 1 in the water faucet device 100 according to the present embodiment, when switching between the straight water discharge and the shower water discharge, the vertical relative positions of the shower forming member 40 and the water spout forming member 60 change. .. Due to this change in the relative position, the size of the opening serving as the shower water discharge hole OP2 changes. Specifically, when the straight water discharge is performed, that is, when the water discharge structure 1 is in the state shown in FIG. 2, the water flowing into the recess 38 is located outside the protrusion 39 and the inner plug member 50. Does not move to the shower spout side. However, in this state, the boss 44b of the boss forming portion 44 of the shower forming member 40 is not inserted into the opening 62a provided in the water outlet forming portion 62 of the water outlet forming member 60. When the water discharge structure 1 is changed from this state to the state shown in FIG. 10, as the shower forming member 40 moves downward and moves to the water discharge port forming member 60 side, the space between the protrusion 39 and the inner plug member 50 is increased. A gap is created in the gap, and a flow of water to the outside of the protrusion 39 and the inner plug member 50 occurs. At the transition stage to the shower water discharge, as shown in FIG. 10 and the like, the boss 44b of the boss forming portion 44 of the shower forming member 40 is fitted to the opening 62a provided in the water outlet forming portion 62 of the water outlet forming member 60. Since the water flows in the state where the water does not enter, the foreign matter on the upstream side of the shower water discharge hole OP2 inside the water discharge structure 1 is easily discharged from the opening 62a provided in the water discharge port forming portion 62. Therefore, in the water discharge structure 1 of the faucet device 100, it is possible to reduce the retention of foreign matter in the shower water discharge hole OP2 or the upstream thereof, and to reduce the clogging itself in the shower water discharge hole OP2.

Even if a part of the shower water discharge hole OP2 is clogged in the state where the shower water discharge hole OP2 is formed, that is, in the state shown in FIG. 10, at the stage of switching from the shower water discharge to the straight water discharge, the shower water discharge hole is formed. The size of the opening forming OP2 changes. At the stage of switching from the shower water discharge to the straight water discharge, the boss 44b of the boss forming portion 44 of the shower forming member 40 is separated (is out) from the opening 62a provided in the water outlet forming portion 62 of the water outlet forming member 60. Occurs. The opening serving as the shower water discharge hole OP2 is formed by a combination of the water discharge port forming member 60 and the shower forming member 40. Therefore, as the relative positional relationship between the water outlet forming member 60 and the shower forming member 40 changes, the relative positional relationship between the members forming the opening of the shower water outlet OP2 changes. Therefore, even if some foreign matter is attached to the shower water discharge port OP2 and clogging occurs, the foreign matter is likely to be removed due to the change in the shape (size) of the opening, and is easily discharged to the outside.

As described above, according to the water discharge structure 1 in the water faucet device 100 according to the present embodiment, when the shower forming member 40 approaches the water discharge port forming member 60, the shower forming portion included in the shower forming member 40 is provided. The plurality of bosses 44b (convex portions) respectively enter any of the openings 62a provided in the water discharge port forming portion 62 of the water discharge port forming member. As a result, a plurality of shower water discharge holes OP2 are formed at positions where the openings 62a of the water discharge port forming portion 62 and the through holes 44a of the shower forming portion overlap with each other to form a shower water discharge passage. On the other hand, when the shower forming member 40 approaches the upstream member 30 and performs straight water discharge, the plurality of bosses 44 b are separated from the opening 62 a of the water discharge port forming portion 62. In this way, the shape (particularly the size) of the openings corresponding to the plurality of shower water discharge holes OP2 changes when switching between the straight water discharge and the shower water discharge. Therefore, in the water discharge structure 1 of the faucet device 100, even if a foreign matter is present upstream of the shower water discharge opening OP2, the foreign matter can be discharged to the downstream side by utilizing the change in the shape of the shower water discharge opening OP2. It will be possible. Therefore, it is possible to prevent the occurrence of clogging due to foreign matter or the like.

The change in the shape of the opening corresponding to the shower water discharge hole OP2 causes a change in the shape of the water flow path, and therefore changes the flow of water on the upstream side toward the opening. Therefore, the change of the flow of water can promote the movement of foreign matter staying around each upstream member constituting the water discharge structure 1, so that the shower water discharge hole OP2 is clogged with foreign matter or the upstream thereof. It is possible to prevent foreign matter from staying on the side.

In the water discharge structure 1 of the faucet device 100 described above, the water discharge port forming member 60 is partitioned by the plurality of ribs 62b that connect the outer cylinder portion 61 and the inner cylinder portion 63, and thus the water discharge port forming portion 62 is formed. A plurality of openings 62a are formed in the. In addition, the boss 44b provided at the downstream end of the shower forming member 40 enters the opening 62a so as to partition a part of the opening 62a. With such a structure, the relative position of the member forming the shower water discharge hole OP2 changes as the shower forming member 40 moves with respect to the water discharge port forming member 60. That is, at least a part of the shower water discharge hole OP2 is configured by a member included in the water discharge port forming member 60 and a member included in the shower forming member 40. In the case of such a configuration, the shape of the shower water discharge port OP2 changes. Therefore, it is possible to prevent foreign matters around the shower water discharge port OP2 from sticking to the vicinity of the shower water discharge hole OP2 and further prevent clogging.

Further, in the water discharge structure 1 of the faucet device 100, as shown in FIG. 9, the boss 44b enters one opening 62a of the plurality of openings 62a and divides the opening 62a into two sections. . More specifically, two substantially identical sections are formed from the opening 62a. As a result, each of the sections formed by the boss 44b forms a shower water discharge hole OP2. In this way, in the case where the opening 62a is divided into two sections by the boss 44b, the through hole 44a is located on the upstream side of the divided opening 62a, so that each functions as the shower water discharge hole OP2. With such a configuration, in each of the plurality of shower water discharge holes OP2, the relative position of the member forming the shower water discharge hole OP2 changes. Therefore, foreign matter around the shower water discharge hole OP2 is further prevented from sticking to the vicinity of the shower water discharge hole OP2, and clogging is prevented.

Further, in the water discharge structure 1 of the above faucet device 100, the slit 46 a (opening) is formed between the plurality of inclined portions 46 in the tubular portion forming the shower forming member 40. As described above, in the shower forming member 40, when the opening is formed in the tubular portion other than the downstream end portion forming the shower forming portion, the foreign matter staying in the shower forming member 40 is on the downstream side, that is, It becomes easy to move the water spout forming member 60 to the water spout forming portion 62 side. That is, the foreign matter can be moved to the downstream side even if the foreign matter stays in the vicinity of the shower forming portion of the shower forming member 40 by utilizing the opening communicating between the inside and the outside. Therefore, it is possible to preferably discharge the foreign matter from the downstream side. Therefore, the foreign matter can be suitably discharged from the inside of the water discharge structure 1, and the occurrence of clogging can be further suppressed.

In the water discharge structure 1 of the faucet device 100 described above, when the shower forming member 40 moves upward (upstream side) and approaches the upstream side member 30, the ends of the plurality of bosses 44b have water discharge ports. It is located apart from the forming portion 62 on the upstream side. Therefore, a large space near the opening 62a provided in the water discharge port forming portion 62 is secured. Therefore, when the shower forming member 40 moves to the upstream member 30 side, it is possible to preferably discharge the foreign matter from the opening 62a of the water discharge port forming portion 62, and further suppress the occurrence of clogging.

(Modification)
In the faucet device 100 including the water discharge structure 1 described in the above embodiment, the configuration of each part can be appropriately changed.

For example, the shapes of the joint member 10, the upstream member 30, the shower forming member 40, the inner plug member 50, the water spout forming member 60, the stopper 70, and the central mouth forming member 80 are not limited to the above-described embodiment, and various modifications may be made. can do. Further, the structure and the like of the structure of each part other than the water discharge structure 1 of the water faucet device 100, that is, the water conduit 110, the water faucet mechanism 120, the water purifying part 130, the cover member 140, and the like may be appropriately changed. it can.

Further, the assembly structure of the joint member 10, the upstream side member 30, the shower forming member 40, the inner plug member 50, the water discharge port forming member 60, the stopper 70, and the central port forming member 80 is the same as the male screw/thread described in the above embodiment. The internal thread may not be used and can be appropriately changed depending on the site.

Further, the water discharge structure 1 may include at least the upstream member 30, the shower forming member 40, and the water discharge port forming member 60. Some of the other members may be omitted, or another member may be substituted. For example, the inner plug member 50 may be omitted, and the portion corresponding to the inner plug member 50 may be configured by the shower forming member 40.

Further, the assembly structure of the joint member 10, the upstream side member 30, the shower forming member 40, the inner plug member 50, the water discharge port forming member 60, the stopper 70, and the central port forming member 80 is the same as the male screw/thread described in the above embodiment. The internal thread may not be used and can be appropriately changed depending on the site.

The shape and arrangement of the shower water discharge hole OP2 are not particularly limited. In the above-described embodiment, the example in which the six openings 62a are arranged in a substantially annular shape by the six ribs 62b in the water discharge port forming member 60 has been shown, but the number of the ribs 62b can be appropriately changed. Although the area of the opening 62a can be increased by reducing the number of the ribs 62b, it is also considered that the strength of the water outlet forming member 60, particularly in the vicinity of the water outlet forming portion 62, decreases. Therefore, the arrangement of the openings 62a and the ribs 62b can be changed based on strength and the like.

Alternatively, the rib 62b may not be provided and one annular opening 62a may be provided. Further, in the above-described embodiment, the example in which the opening 62a is arranged in a single substantially annular shape has been described, but the opening 62a may be arranged in two or more double substantially annular shapes.

In addition, as described in the above embodiment, the boss 44b of the shower forming member 40 is inserted into the opening 62a provided in the water outlet forming portion 62 of the water outlet forming member 60, and the through hole 44a of the shower forming member 40 is formed. A shower water discharge hole OP2 is formed at a position overlapping the opening 62a. Therefore, the arrangement of the boss 44b and the through hole 44a can be appropriately changed so that the shower water discharge hole OP2 is formed in a desired size.

Further, the shape of the inclined portion 46 of the shower forming member 40 and the like can be changed as appropriate. Although the case where the inclined portion 46 is provided in the shower forming member 40 has been described in the above embodiment, the inclined portion 46 may not be provided.

In the above embodiment, the case where the shower water outlet OP2 and the straight water outlet OP1 are formed at different positions from each other will be described. When the flow path for straight water discharge and the flow path for shower water discharge are different from each other. However, the flow path for straight water discharge and the flow path for shower water discharge may be designed to be the same flow path. For example, even when the shower forming member 40 is close to the upstream side member 30, the upstream side member 30 is surrounded by the state in which water can flow to the outside of the protruding portion 39 of the upstream side member 30 and the inner plug member 50. Water is configured to flow between the inner peripheral surface of the wall portion 33 and the outer peripheral surface of the inner tubular portion 42 of the shower forming member 40. In this case, water is discharged downward from the water outlet forming portion 62 in a shape corresponding to the opening 62a of the water outlet forming member 60. By making the size of the opening 62a sufficiently larger than the shower water discharge hole OP2, the water discharged from the opening 62a can be brought into a substantially straight water discharge state. With such a configuration, both the straight water discharge and the shower water discharge can be realized without providing the straight water discharge port OP1 at the center unlike the water discharge structure 1.

As described above, the faucet device 100 including the water discharge structure 1 described in the present embodiment can be appropriately changed.
