Description

  The present invention relates to a faucet device capable of switching a plurality of discharge shapes of running water.

  As such a faucet device, there exists a technique shown, for example in Unexamined-Japanese-Patent No. 2004-73958 (patent document 1). This faucet device includes a switching handle that can be rotated so as to switch the water discharge shape between a shower shape and a straight shape. A valve seat member having two communication holes communicating with the water flow path is fixed inside the faucet body constituting the faucet apparatus. The valve seat member is in contact with a valve body having a hole portion that switches to two connection modes with respect to the communication hole of the valve seat member. A straight discharge port through which straight-shaped running water is discharged is provided at the center of the valve body, and a shower discharge port through which shower-shaped running water is discharged is provided around the valve body. The switching handle and the valve body engage with each other and rotate together. Therefore, by rotating the switching handle, the valve body can be rotated relative to the valve seat member to switch between the two water discharge shapes.

  The switching handle is cylindrical and constitutes the outer edge of the tip of the faucet device. The cover body which covers a faucet instrument main body is provided in the edge part of the base end side of a faucet instrument among switching handles. The outer surface of the switching handle and the outer surface of the cover body form a continuous spindle shape without any step, and the opposite end surfaces of both are formed in a direction perpendicular to the spindle-shaped surface. That is, the gap between the switching handle and the cover body can be visually recognized in a state where the spindle shape is divided.

  Further, the switching handle has a plurality of operation fins that are formed so as to protrude in the vertical direction from the outer surface of the handle body based on a cylindrical handle body. The operation fin is a plate-like member and extends along the water discharge direction. When the user places a finger on the operation fin and applies a force in the vertical direction of the operation fin, the switching handle rotates in the circumferential direction. The operation fins are provided in a dotted shape along the circumferential direction of the handle body.

JP 2004-73958 A

  However, in such a configuration of the switching handle, the position of the gap between the switching handle and the cover body is always visible to the user. When the faucet device is used, the gap may be splashed with water from the outside or water may leak from the inside of the faucet device, and dirt such as scale is likely to accumulate. Users are very sensitive to such dirt, and when dirt accumulates on the surface of a faucet instrument, it immediately gives an unhygienic impression on the faucet instrument.

  Further, since the operation fins are erected on the surface of the handle body, they intersect at a right angle, for example, at a boundary position between the surface of the operation fin and the surface of the handle body to form a corner. Such corners are likely to accumulate dirt such as scale. This position is also very easy to see from the user. Since the operation fin is a member that is frequently operated by the user, the accumulation of dirt here further increases the unsanitary impression.

  As described above, in the conventional faucet device, although the operation of switching the water flow shape is easy, the impression at the time of use may be impaired, and there is still room for improvement.

  In view of such a situation, conventionally, it is desired to provide a faucet device that can easily switch the water flow mode and can maintain a beautiful appearance for a long time.

(Feature configuration)
The characteristic configuration of the faucet device according to the present invention is:
A faucet body provided with a flow path;
A hole for obtaining water discharge in a first water discharge shape, and a screen member that rotates relative to the faucet body and switches the water discharge shape to the first water discharge shape or other shapes;
It is in the point which has the operation part integrally formed along the water discharging direction from the front end surface of the screen member.

(effect)
By forming the operation part that rotates the screen member so as to switch the water discharge shape integrally with the screen member, no gap is formed at the boundary position between the screen member and the operation part, and accumulation of dirt is suppressed. Moreover, the number of parts of the faucet device is reduced, and assembly is facilitated.

  Further, the operation part of the faucet device is a part that is always touched by the user during use, and needs to be kept clean. Although the operation portion is integrally formed to protrude from the screen member, dirt such as water is likely to accumulate at the corner portion formed at the boundary position between the two members.

  Therefore, in this configuration, the operation portion is formed to project from the front end surface of the screen member along the water discharge direction. That is, the base end portion of the operation unit is behind the screen member and is not visible to the user. Thereby, the faucet device which can maintain a beautiful external appearance over a long period of time can be obtained.

(Feature configuration)
As the faucet device according to the present invention, the screen member is inserted into a cylindrical edge formed at the tip of the faucet body, and the inner surface of the cylindrical edge and the outer surface of the screen member It is convenient that an annular gap is formed between the two along the insertion direction of the screen member.

(effect)
Since the extending direction of the gap is along the inner surface of the cylindrical edge, the gap is hardly visible to the user. Therefore, dirt such as dirt accumulated between the screen member and the faucet body becomes inconspicuous, and a faucet device that can maintain a beautiful appearance for a long time can be obtained.

(Feature configuration)
In the faucet device according to the present invention, in the cross-sectional view including the axis of the screen member, the inner surface and the outer surface are parallel, and a bent portion is formed between the outer surface and the tip surface. The outer surface may be configured not to be exposed from the cylindrical edge.

(effect)
If it is this structure, only the front end surface which has a predetermined angle with an outer side surface will be exposed from a cylindrical edge part among the surfaces of a screen member. Therefore, even if moisture is retained between the screen member and the cylindrical edge portion and water scale accumulates, the distance from the inner surface of the cylindrical edge portion is outside the bent portion of the surface of the screen member. Because it spreads, it becomes difficult to retain water. Therefore, the dirt is blocked by the bent portion and does not spread further, and the faucet device is kept clean.

(Feature configuration)
In the faucet device according to the present invention, in the operation portion, a portion that is integrally projected from the surface of the screen member along the water discharge direction is defined as a first convex portion, and the first convex portion is provided. The second convex portion extending in the radially outward direction of the screen member is integrally formed, and the second convex portion is viewed in a direction perpendicular to the extending direction of the first convex portion and the extending direction of the second convex portion. Of the edges of the projections, the far side edge along the water discharge direction from the tip surface of the screen member is closer to the far side in the extending direction of the second protrusions along the water discharge direction. Can be configured to displace

(effect)
In this configuration, since the extending direction of the second convex portion is opposite to the water discharging direction, even when water discharged from the front end surface of the screen member is transmitted to the operation portion, the tip end of the second convex portion is reached. It is blocked from being transmitted. Therefore, accumulation of scales or the like at the lower end portion of the second convex portion is prevented.

  In addition, since the water discharge is not transmitted to the distal end portion of the operation unit, the state of the water flow discharged from the screen member is improved. Therefore, the water flow shape switching function is reliably exhibited, and the texture of the faucet device can be improved.

(Feature configuration)
In the faucet device according to the present invention, the screen member and the operation portion may be formed of a resin material, and the operation portion may be provided with a recess that opens in the water discharge direction.

(effect)
The operation unit is a part operated by the user when changing the water discharge shape, and a certain volume is required to secure a predetermined strength. If an attempt is made to obtain the screen member and the operation portion by, for example, injection molding using a resin material, resin shrinkage may occur when the resin temperature decreases due to the volume, and the appearance of the operation portion may be disturbed. Therefore, a recess is formed in the operation part.

  However, by opening such a recess in the water discharge direction, the outer surface of the operation unit can be formed with high accuracy, and the area of the end surface of the lower edge of the operation unit can be reduced. That is, when the operation unit is viewed from the direction opposite to the water discharge direction, the resin material is distributed so as to surround the recess. In this case, even if the water discharged from the screen member tries to move to the tip through the operation portion, it is possible to inhibit the water from reaching the tip as a result of the small resin area at the end. Therefore, for example, a faucet device having high texture of switching the water discharge shape can be obtained without disturbing the shape of the water discharge such as a shower shape.

(Feature configuration)
In the faucet device according to the present invention, the first water discharge shape is a shower shape, and a plurality of the hole portions are provided at a predetermined interval from each other on the distal end surface. It is convenient if the interval between the boundary and the hole portion closest to the boundary is set wider than the predetermined interval.

(effect)
As in this configuration, by setting the interval from the operation portion to the hole portion wider than the interval between the hole portions related to water discharge, when the water discharge shape is a shower shape, the water discharge reaches the operation portion. Opportunities are reduced and the shower shape is prevented from being disturbed. Therefore, it is possible to obtain a faucet device having operability with a good texture.

(Feature configuration)
The faucet device according to the present invention has a faucet body provided with a flow path and a hole for obtaining water discharge having a first water discharge shape, and the water discharge shape of the water by rotating relative to the water faucet body. And a screen member integrally formed with a water discharge shape or other shape, and the screen member is inserted into a cylindrical edge formed at the tip of the faucet body, and the cylindrical edge It is convenient that an annular gap is formed between the inner surface of the screen member and the outer surface of the screen member along the insertion direction of the screen member.

(effect)
Since the annular gap formed between the inner surface of the faucet body and the outer surface of the screen member is along the insertion direction of the screen member, it is difficult to see the dirt accumulated in the gap. Therefore, a faucet device that can maintain a beautiful appearance over a long period of time can be obtained.

(Overview)
One embodiment of a faucet device J according to the present invention will be described with reference to the drawings.
The faucet device J of the present embodiment is used as a faucet of a kitchen or the like, for example, and a screen member S1 for switching the water discharge shape is attached to the tip of a faucet body J1 having a flow path inside. As shown in FIG. 1, the faucet body J1 is covered with a cover C. In particular, a first cover C1 that covers the upper part and a second cover C2 that covers the lower part are attached to the tip of the faucet body J1. It has been. Among these, the circular opening is provided in the lower end part of the 2nd cover C2, and the cyclic | annular screen member S1 is inserted here.

  The screen member S1 in the present embodiment is disposed inside the opening area that opens to the lower side of the second cover C2. In particular, the screen member S1 includes a large number of first holes H1 in the circumferential direction in the outer peripheral region of the opening of the second cover C2 along the circumferential direction in which the water discharge shape is a shower shape as the first water discharge shape. An operation portion 1 that rotates the screen member S1 within a predetermined angle range is provided on the tip end surface S11 formed at the lower end of the screen member S1.

  As shown in FIG. 2, an annular strainer case S2 is provided on the center side of the screen member S1. Here, there is one second hole H2 that opens in the center and has a water discharge shape that is a straight shape, and an outer periphery of the second hole H2 that has an intermediate water discharge shape between the shower shape and the straight shape. A plurality of third holes H3 having a shape of are provided. The strainer case S2 is screwed into a switching plate S4 attached to the faucet body J1, and at that time, engages with an inner edge portion of the screen member S1 to fix the screen member S1 to the switching plate S4.

  Between the strainer case S2 and the switching plate S4, a straightening shape with a uniform water discharge shape is provided. A mesh member S31 having a beautiful cylindrical shape is provided. The mesh member S31 is formed by stacking, for example, three metal mesh materials having a predetermined fineness. Although illustration is omitted, the mesh material is formed by connecting the ends of three substantially circular mesh materials, and a three-layer mesh member S31 is obtained by bending the connection portion.

  On the other hand, as shown in FIGS. 2 and 5, the screen member S <b> 1 is retained by the strainer case S <b> 2. At that time, the screen member S1 presses against the switching bush S5 in the direction opposite to the water discharge direction, and engages the engaging portions S14 formed separately on both as shown in FIG. For this engagement, three protrusions provided on the peripheral edge of the screen member S1 are used. One of the protrusions has a long length along the circumferential direction, and the switching bush S5 and the screen member S1 are always engaged in the correct phase. The switching bush S5 is pre-engaged with the switching plate S4 and assembled together. Although illustration is omitted, the switching plate S4 is formed with three types of hole portions that respectively communicate with the first hole portion H1 to the third hole portion H3.

  These screen member S1, strainer case S2, rectifying member S3, switching bush S5, and switching plate S4 all rotate together. Of these, an annular flange portion (not shown) formed on the outer peripheral portion of the switching plate S4 is inserted into an annular recess provided on the faucet body J1 side, and a retaining key protrudes from the inner wall of the annular recess. Further, the flange portion of the switching plate S4 is prevented from coming out of the annular recess, and the integral member connected to the screen member S1 can be rotated relative to the faucet body J1.

  A switching valve S6 provided in a non-rotatable manner on the faucet body J1 is urged against the switching plate S4. The upstream of the switching valve S6 communicates with the raw water flow path or the purified water flow path of the water supply. By rotating the switching plate S4, three holes formed in the switching valve S6 are provided in the switching plate S4. Corresponds to each hole in the set. By changing this corresponding position, the water from the upstream is transferred to the first hole H1 related to the shower shape, or the second hole H2 related to the straight shape, and the third hole H3 related to the water discharge shape between them. You can communicate with each other separately.

  In the rotation operation of the operation unit 1 at this time, a click mechanism using a leaf spring is provided between the switching bush S5 and the faucet body J1, and three scales C23 provided on the surface of the second cover C2. The water discharge shape can be switched over. In this embodiment, a leaf spring is used for the click mechanism, but a coil spring in which a linear material is wound spirally can be used instead of the leaf spring. Specifically, a compression coil spring is used among the coil springs, and the compression coil spring is provided on one of the switching bush S5 or the faucet body J1. In this case, a contact piece may be disposed at the tip of the compression coil spring, and a recess for engaging the contact piece may be provided on the other side of the switching bush S5 or the faucet body J1. The material of the leaf spring or coil spring can be a metal material such as steel, or a non-metal material such as resin, but it is preferable to use a metal material to ensure high strength and durability.

  If it is this structure, the screen member S1 can be simultaneously removed from switching bush S5 by removing strainer case S2 from switching board S4. Since the operation unit 1 is integrally formed with the screen member S1, the number of members related to the attachment and detachment is reduced, the cost can be reduced, and the risk of component loss can be reduced.

(Screen material)
The faucet device J of the present embodiment makes dirt such as scale accumulated with use as inconspicuous as possible. For this reason, as shown in FIG. 1, the entire front end of the faucet body J1 is covered with only the first cover C1 and the second cover C2, and the number of connecting portions between the members is reduced. Other members that can be seen by the user include the operation unit 1 and a screen member S1 that is linked to the operation unit 1. By devising these shapes, it is difficult to see dirt.

  In the present embodiment, the screen member S1 is inserted along the water discharge direction into a cylindrical edge C21 formed at the tip of the faucet body J1. For this reason, an annular gap 2 along the insertion direction of the screen member S1 is formed between the inner surface C22 of the cylindrical edge C21 and the outer surface S12 of the screen member S1. Normally, dirt such as scale is likely to accumulate in the gap 2, but in this embodiment, the facing surface of the screen member S 1 and the cylindrical edge C 21 has a predetermined angle θ with respect to the water discharge direction. It is like that. That is, it is a surface provided on the screen member S1, and is exposed to the bottom from the cylindrical edge C21 and is normal to the surface facing the inner surface C22 of the cylindrical edge C21, and the cylindrical edge C21 is provided. The normal line of the inner surface C22 that faces the screen member S1 is set to be perpendicular to the water discharge direction. However, the angle can be changed within a predetermined range. For example, the angle θ is preferably 70 to 110 degrees, more preferably 80 to 100 degrees, and particularly preferably 90 degrees.

  By configuring in this way, the extending direction of the gap 2 is along the inner surface C22 of the cylindrical edge C21, so that the gap 2 is hardly visible to the user. Therefore, dirt such as dirt accumulated between the screen member S1 and the faucet body J1 becomes inconspicuous, and a faucet device J that can maintain a beautiful appearance for a long time can be obtained.

  In addition, as shown in FIG. 4, as for the dimension a of the said clearance gap 2, 0.1-10 mm is good. When the thickness is less than 0.1 mm, dirt accumulated in the gap 2 is exposed to the outside and is easily noticeable. Therefore, 0.5 mm or more, particularly 0.8 mm or more is preferable. However, if the gap 2 becomes too wide, the installation area of the first hole H1 becomes narrow, or the outer diameter of the cylindrical edge C21 becomes excessive to secure the gap 2, so the dimension a of the gap 2 Is preferably 5 mm or less, particularly 2 mm or less.

  In order to prevent the dirt between the screen member S1 and the cylindrical edge C21 from being seen, it is desirable that the outer surface S12 of the screen member S1 is not exposed from the cylindrical edge C21. Therefore, a bent portion S13 is provided between the outer surface S12 of the screen member S1 and the tip surface S11 of the screen member S1, and the outer surface S12 is a cylindrical edge portion in a cross-sectional view including the axis X of the screen member S1. It is configured not to be exposed from C21. That is, the inner surface C22 of the cylindrical edge C21 and the outer surface S12 of the screen member S1 are often parallel, but at least the parallel portion is not exposed from the cylindrical edge C21. In addition, when setting it as the structure which this parallel part exposes from the cylindrical edge part C21, it is good to make the exposed length into 3 mm or less, 2 mm or less, especially 1 mm or less.

  Incidentally, FIG. 4 shows an example in which the outer surface S12 is linear, and an arc-shaped cross section is formed on the outer side from the position facing the end of the cylindrical edge C21. In this case, the boundary position between the linear area and the arc-shaped area is the bent portion S13. Thus, when the angle of the outer surface S12 changes even a little, the flow along the surface of the outer surface S12 is inhibited by the influence of the surface tension of water. In other words, it is difficult for dirt to adhere to the area beyond the bend S13, and it is difficult for the user to see it. Therefore, in the case of FIG. 4, when the screen member S1 is viewed from the direction perpendicular to the water discharge direction, the arc-shaped region is slightly seen. This is the outer surface S12 to which dirt easily adheres. It is a different area.

  With this configuration, the outer surface S12 of the screen member S1 is not exposed from the cylindrical edge C21 of the faucet body J1, but is exposed from the cylindrical edge C21 at a tip having a predetermined angle with the outer surface S12. It becomes only surface S11. Therefore, even if water or the like accumulates between the screen member S1 and the faucet body J1, dirt on the part is blocked by the bent portion S13 and hardly spreads, and the faucet device J has a clean and beautiful appearance. Maintained.

  However, when the part ahead of the bending part S13 among screen members S1 is circular, for example, the user will be able to visually recognize screen member S1 from the side. Although the site | part which can be visually recognized is not parallel to the inner surface C22 of the cylindrical edge part C21, the stain | pollution | contamination adhering to the said area | region becomes conspicuous because a wide area | region can be visually recognized. Therefore, as shown in FIG. 4, the arc-shaped surface continues from the bent portion S13 of the screen member S1 toward the distal end, and the region from the distal end surface S11 to, for example, the conical surface is arc-shaped.

  With respect to this arc-shaped region, the length b along the direction of the axis X is preferably 0 to 3 mm when viewed in a direction perpendicular to the direction of the axis X. When the length b is 0, it is difficult to extend the operation unit 1 in the radially outward direction, for example. Therefore, in order for the operation part 1 to eliminate the interference between the laterally extending part and the screen member S1, the length b is preferably 0.5 mm or more, and more preferably 0.8 mm or more. On the other hand, if it exceeds 3 mm, the range in which the outer side surface S12 of the screen member S1 can be seen from the side becomes large, and the design properties deteriorate. Therefore, the length b is preferably 2 mm or less, and more preferably 1.5 mm or less.

(Operation section)
In order to make the dirt of the screen member S1 inconspicuous, it is necessary to devise the operation unit 1 provided on the screen member S1. In particular, since the operation unit 1 is a part that the user frequently touches, the user tends to be sensitive to the presence or absence of dirt. Therefore, in the faucet device J of the present embodiment, as shown in FIG. 1, the operation portion 1 is formed integrally with the screen member S <b> 1, and is formed so as to protrude from the front end surface S <b> 11 of the screen member S <b> 1 along the axis X. Can be.

  Thus, by forming the operation unit 1 integrally with the screen member S1, a contact portion between the members is not formed at the boundary position between the screen member S1 and the operation unit 1. Therefore, the accumulation degree of dirt is reduced.

  Moreover, if the operation part 1 protrudes along the direction of the axis X from the front end surface S11 of the screen member S1, the part which can be seen from the user in the operation part 1 is reduced. Therefore, the dirt adhering to the operation unit 1 is not noticeable.

  Further, although the screen member S1 and the operation unit 1 are integrally formed, a corner is formed at the boundary position between the two, so that dirt easily accumulates at this part. In this respect, as in the present configuration, the operation portion 1 is formed so as to protrude from the front end surface S11 of the screen member S1, so that the corner itself is difficult to be seen by the user. Therefore, it is possible to obtain a faucet device J that can maintain a beautiful appearance for a long time.

  In addition, by forming the operation part 1 integrally with the screen member S1, the number of parts of the faucet device J is reduced, and the trouble of parts management and assembly is reduced.

  As for the shape of the operation part 1, as shown in FIG. 2, the first convex part 11 is defined as a part that is integrally projected from the surface of the screen member S1 along the direction of the axis X. 11 may be formed integrally with the second convex portion 12 extending in the radially outward direction of the screen member S1.

  By providing the second convex portion 12 in this way, the tip of the operation portion 1 can be protruded further outward than the outer surface S12 of the second cover C2, and the operation of the screen member S1 becomes easier.

  For example, as shown in FIG. 4, the second convex portion 12 has the second convex portion 12 in the direction perpendicular to the extending direction of the first convex portion 11 and the extending direction of the second convex portion 12. Of the edges, the lower edge 15 on the far side along the direction of the axis X from the front end surface S11 of the screen member S1 is displaced toward the upper side in the water discharge direction toward the far side in the extending direction of the second convex part 12. It can be constituted as follows. That is, the extending direction of the lower edge 15 of the operation unit 1 is a shape that is rounded up toward the outside.

  If it is this structure, since the extension direction of the 2nd convex part 12 reverses the direction of water discharge, even when the water discharged from the front end surface S11 of the screen member S1 is transmitted to the operation part 1, the 2nd convex part 12 is provided. Can be prevented from reaching the tip of the. Therefore, accumulation of scales or the like at the lower end portion of the second convex portion 12 is prevented.

  In addition, since the water discharge is not transmitted to the distal end portion of the operation unit 1, the state of the water flow discharged from the screen member S1 is improved. Therefore, the water flow shape switching function is reliably exhibited, and the texture of the faucet device J can be improved.

  As shown in FIG. 4, it is preferable that the angle e between the lower edge 15 of the operation unit 1 and the radial direction is 0 to 30 degrees. If it is less than 0 degree, the water discharged from the first hole H1 or the like is easily transmitted to the outside of the operation unit 1, and the water discharge state is disturbed. Moreover, since the lower edge 15 of the operation part 1 gets wet frequently, dirt becomes easy to adhere. Therefore, the angle e is preferably 5 degrees or more, particularly 8 degrees or more. If it exceeds 30 degrees, when the upper edge 16 of the operation unit 1 is pinched and operated, an excessive torsional force may act on the base end portion of the operation unit 1 and the durability may be impaired. Therefore, the angle e is preferably 20 degrees or less, and particularly preferably 10 degrees or less.

  Further, as shown in FIGS. 3 and 4, if the inner edge and the lower edge of the first convex portion 11 are sharpened, the water discharged from the first hole H <b> 1 is removed from the operation portion 1. It becomes difficult to be transmitted to the other side.

  When the operation part 1 has the 2nd convex part 12, the width | variety c of the 2nd convex part 12 along the direction of the axial center X has preferable 5-20 mm, for example. If it is less than 5 mm, the finger catching is reduced and the operability is deteriorated. Accordingly, it is preferably 10 mm or more, particularly 13 mm or more. On the other hand, if the width c is too wide, the bending stress acting on the operation portion 1 when a force is applied above the second convex portion 12 becomes large, and the durability tends to be lowered. Therefore, the width c is preferably 17 mm or less, particularly 15 mm or less.

  The length d along the radial direction between the radially outermost position of the operating portion 1 and the cylindrical edge C21 of the second cover C2 is preferably 5 to 20 mm. If it is less than 5 mm, the finger hooking becomes small and the operational feeling is lowered. Therefore, 8 mm above, especially 10 mm or more is preferable. On the other hand, if it exceeds 20 mm, the amount of protrusion in the radial direction becomes excessive, and the user's hand who performs the cooking operation easily touches carelessly. Therefore, the length d is preferably 15 mm or less, particularly 12 mm or less.

The cross-sectional area f at the narrowest position in the operation unit 1 is preferably ³ to 25 mm ² , for example. If it is less than 3 mm < ² >, the bending strength of the operation part 1 will fall and durability will fall. Therefore, 6 mm ² or more, particularly 12 mm ² or more is preferable. ^{On the other hand} , if it exceeds 25 mm ² , the area for installing the shower water discharge holes in the surface area of the screen member S1 becomes narrow, or the entire head is easily increased in size to ensure this area. Therefore, it is preferably 20 mm ² or less, particularly 16 mm ² or less.

  In the case where the screen member S1 and the operation unit 1 are integrally formed of a resin material, for example, as shown in FIG. 4, the third projection 13 is further formed in the direction opposite to the water discharge direction from the tip of the second projection 12. When forming, the operation part 1 is good to provide the recessed part 14 opened to a water discharge direction.

  The operation unit 1 is a part operated by the user when changing the water discharge shape, and a certain volume is required to secure a predetermined strength. If the screen member S1 and the operation unit 1 are to be obtained by injection molding using, for example, a resin material, the volume of the resin causes a resin shrinkage when the resin temperature is lowered, and the appearance of the operation unit 1 may be disturbed. Therefore, it is preferable to form a recess 14 in the operation unit 1.

  Moreover, by opening such a recess 14 in the water discharge direction, the area of the end face of the lower edge 15 in the operation unit 1 is reduced as shown in FIG. When the operation unit 1 is viewed from the direction opposite to the water discharge direction, the resin material is distributed so as to surround the recess 14. In this case, even if the water discharged from the screen member S1 tries to move to the tip through the operation unit 1, it is possible to inhibit the water from reaching the tip as a result of the area of the end face of the lower edge 15 being small. Therefore, for example, the faucet device J having a high texture of switching the water discharge shape can be obtained without disturbing the shape of the water discharge such as a shower shape.

  In the faucet device J of the present embodiment, in order to form shower-shaped water discharge as the first water discharge shape, a plurality of holes are provided at a predetermined interval L2 from each other on the tip surface S11 of the screen member S1. . At this time, as shown in FIG. 3, it is convenient that the interval L1 between the boundary between the operation unit 1 and the tip surface S11 and the hole closest to the boundary is set wider than the predetermined interval L2 between the holes. It is.

  As in this configuration, by setting the interval L1 from the operation unit 1 to the hole to be wider than the interval L2 between the holes related to the shower-shaped water discharge, when the water discharge shape is a shower shape, the water discharge Is less likely to be transmitted to the operation unit 1, and the shower shape is prevented from being disturbed. Therefore, it is possible to obtain a faucet device J having a good feel and operability.

(Material)
The screen member S1 and the operation unit 1 of the present embodiment preferably use a thermoplastic resin in order to ensure moldability and predetermined rigidity. Among thermoplastic resins, ABS (acrylonitrile, butadiene, styrene copolymer synthetic resin), ASA (acrylonitrile, acrylate, styrene copolymer synthetic resin), PP (polypropylene resin), which are high in strength and excellent in design feasibility, are preferable. In particular, ABS / ASA is preferable in terms of high strength, and is excellent in impact resistance, and ABS is preferable from the viewpoint of low cost and moldability.

[Another embodiment]
The faucet device J according to the present invention can also be implemented as follows. That is, as shown in FIG. 6, it has a faucet body J1 having a flow path and a hole for obtaining water discharge having a first water discharge shape, and the water discharge shape is changed to the first by rotating relative to the water faucet body J1. And a screen member S1 integrally formed with an operation unit 1 for switching to a water discharge shape or other shapes. Of these, the screen member S1 is inserted into the cylindrical edge C21 formed at the tip of the faucet body J1, so that the screen is between the inner surface C22 of the cylindrical edge C21 and the outer surface S12 of the screen member S1. An annular gap 2 is formed along the insertion direction of the member S1.

  In the present embodiment, the gap 2 formed between the outer surface S12 of the screen member S1 and the inner surface C22 of the cylindrical edge C21 of the second cover C2 is along the insertion direction of the screen member S1 as described above. Although it is the same as embodiment, it differs in that a part of the outer side surface S12 of the screen member S1 is exposed to the outside of the cylindrical edge C21. The faucet device J is normally used while the user looks down. Therefore, even if the outer surface S12 of the screen member S1 is exposed to some extent from the cylindrical edge C21 as in this embodiment, the dirt spread on the outer surface S12 is always behind the cylindrical edge C21. Dirt is not always noticeable. Whether or not dirt can be visually recognized depends largely on the direction of the gap 2 where dirt accumulates. Therefore, even in the faucet device J of this embodiment, the effect of maintaining a beautiful and clean appearance over a long period can be expected.

  Unlike the examples of the above embodiments, the operation unit 1 and the screen member S1 may be configured as separate members. When both are constituted by separate members, dirt is likely to accumulate at the abutting portions as compared with a case where they are formed integrally. However, since the operation part 1 of this invention protrudes below from the front end surface S11 of the screen member S1, the mutual contact part is usually in a position that is difficult for the user to visually recognize. Therefore, the effect of maintaining a beautiful and normal appearance can be maintained even when the operation unit 1 is constituted by another member.

  The faucet device of the present invention is applicable to various faucet devices such as a sink that can be switched to a plurality of types of water flow shapes such as a straight water flow and a shower water flow.
