Summary of the Invention

Problems to be Solved by the Invention

[0005] When the water discharged from the water spray holes has a high flow velocity, undesired water splashing occurs. The present inventor regarded this as a problem and intensively studied countermeasures to suppress such water splashing, and found that by making the flow velocities of the water discharged from the plurality of water spray holes more uniform, water splashing can be suppressed.

[0006] Then, the inventor of the present invention has found that when each of some of the plurality of sprinkler holes is provided on the extension line of any of the plurality of outflow holes, by raising the periphery of the end portion on the back side of each of the some sprinkler holes toward the sprinkling space side to form a boss portion, the flow velocity of the water discharged from each of the some sprinkler holes can be effectively reduced, and the flow velocities of the water discharged from all the sprinkler holes can be made more uniform.

[0007] Further, the inventor of the present invention has also found that even when a collision wall is provided in the sprinkling space at a position intersecting the extension line of each of the plurality of outflow holes, by raising the periphery of the end portion on the back side of each of some of the plurality of sprinkler holes toward the sprinkling space side to form a boss portion, the flow velocity of the water discharged from each of the some sprinkler holes can be effectively reduced, and the flow velocities of the water discharged from all the sprinkler holes can be made more uniform.

[0008] The present invention has been conceived based on the above findings. An object of the present invention is to provide a faucet device including a spout provided with a plurality of sprinkler holes, the faucet device having suppressed water splashing.

Means for Solving the Problems

[0009] The present invention is a faucet device including a spout provided with a plurality of sprinkler holes. Inside the spout, a sprinkling space communicating with each end portion on the back side of the plurality of sprinkler holes is provided. Further inside the sprinkling space, a sprinkling back space is provided via a plurality of outflow holes. On the base end side of the spout, a water supply passage is provided. The water supply passage and the sprinkling back space are communicated by a communication flow passage. Each of some of the plurality of sprinkler holes is provided on the extension line of any of the plurality of outflow holes. The periphery of the end portion on the back side of each of the some sprinkler holes among the plurality of sprinkler holes rises toward the sprinkling space side to form a boss portion. The faucet device is characterized by this.

[0010] According to the present invention, since each of some of the plurality of watering holes is provided on an extension line of any of the plurality of outflow holes, there is a concern that the flow velocity of the water discharged from each of these some watering holes may become too high. However, since the periphery of the end portion on the inner side of each of these some watering holes bulges toward the watering space side to form a boss portion, the flow velocity of the water discharged from each of these some watering holes is appropriately suppressed, and the flow velocities of the water discharged from all the watering holes can be made more uniform. As a result, the occurrence of water splashing can be effectively suppressed.

[0011] Generally, the plurality of watering holes are arranged in a matrix in the extending direction of the spout and in the left-right direction perpendicular to the extending direction. And in the mode called "sweeping water discharge", the distance between the watering hole on the most proximal side and the watering hole on the most distal side in the extending direction is larger than the distance between the watering hole on the most left end side and the watering hole on the most right end side in the left-right direction. In this case, a difference (bias) in the flow velocity of the discharged water is likely to occur between the watering hole on the most proximal side and the watering hole on the most distal side in the extending direction. However, according to the present invention, since the flow velocities of the water discharged from all the watering holes can be made more uniform, the occurrence of water splashing can be effectively suppressed.

[0012] Also, generally, due to the layout of the internal structure of the spout, the communication flow path is configured to turn back from the distal end side to the proximal end side inside the spout. In this case, combined with the turbulence of the water flow in the communication flow path, a difference (bias) in the flow velocity of the water discharged from each watering hole is likely to occur. However, according to the present invention, since the flow velocities of the water discharged from all the watering holes can be made more uniform, the occurrence of water splashing can be effectively suppressed.

[0013] Also, it is preferable that a collision wall is provided in the watering space at a position intersecting the extension line of each of the plurality of outflow holes. According to this, since the flow velocity of the water is also appropriately suppressed by the collision wall, the occurrence of water splashing can be more effectively suppressed.

[0014] In this case, it is more preferable that the collision wall extends toward the spout surface side at the proximal end side and the distal end side. According to this, the inhibitory effect of the collision wall on the water flow velocity does not become excessive, and the generation of water splashing can be more effectively suppressed. When the collision wall extends toward the inner side at the proximal end side and the distal end side, the water flow velocity is excessively suppressed at this part, which is not preferable for the uniformization of the water flow velocity discharged from all the watering holes.

[0015] Moreover, the present invention is a faucet device including a spout provided with a plurality of watering holes, in which a watering space communicating with each end on the inner side of the plurality of watering holes is provided inside the spout, and a watering inner space is provided further inside the watering space via a plurality of outflow holes. A water supply path is provided on the proximal end side of the spout, and the water supply path and the watering inner space are communicated by a communication flow path. A collision wall is provided in the watering space at a position intersecting the extension line of each of the plurality of outflow holes, and the periphery of each end on the inner side of some of the plurality of watering holes bulges toward the watering space side to form a boss portion. It is a faucet device characterized by this.

[0016] According to the present invention, when a collision wall is provided in the watering space at a position intersecting the extension line of each of the plurality of outflow holes, the periphery of each end on the inner side of some of the plurality of watering holes bulges toward the watering space side to form a boss portion, so that the water flow velocity discharged from each of these some watering holes is appropriately suppressed, and the water flow velocity discharged from all the watering holes can be made more uniform. Thereby, the generation of water splashing can be effectively suppressed.

[0017] Also in this case, it is more preferable that the collision wall extends toward the spout surface side at the proximal end side and the distal end side. According to this, the inhibitory effect of the collision wall on the water flow velocity does not become excessive, and the generation of water splashing can be more effectively suppressed.

Effect of the Invention

[0018] According to one aspect of the present invention, since each of some of the plurality of sprinkler holes is provided on an extension line of any of the plurality of outflow holes, there is a concern that the flow rate of the water discharged from each of these sprinkler holes may become too high. However, since the periphery of the end portion on the back side of each of these sprinkler holes bulges toward the sprinkling space side to form a boss portion, the flow rate of the water discharged from each of these sprinkler holes is appropriately suppressed, and the flow rates of the water discharged from all the sprinkler holes can be made more uniform. As a result, the occurrence of water splashing can be effectively suppressed.

[0019] Alternatively, according to another aspect of the present invention, when a collision wall is provided in the sprinkling space at a position intersecting the extension line of each of the plurality of outflow holes, since the periphery of the end portion on the back side of each of some of the plurality of sprinkler holes bulges toward the sprinkling space side to form a boss portion, the flow rate of the water discharged from each of these sprinkler holes is appropriately suppressed, and the flow rates of the water discharged from all the sprinkler holes can be made more uniform. As a result, the occurrence of water splashing can be effectively suppressed.

Mode for Carrying Out the Invention

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic front view of a faucet device 1 according to an embodiment of the present invention.

[0022] The faucet device 1 of the present embodiment is a hot and cold water mixing faucet capable of adjusting the flow rate and temperature of raw water, and is also a faucet that can selectively use purified water instead of raw water (hot and cold water). For example, it is arranged on the rear side (depth side) of the sink in the kitchen.

[0023] A hot water supply port 2, a water supply port 3, and a purified water supply port 61 are provided on the lower wall surface of the sink in the kitchen. The hot water supply port 2 is connected to the hot and cold water mixing valve 21 in the base end portion 10 of the faucet device 1 via a hot water supply solenoid valve 52 and a hot water supply pipe 22. The water supply port 3 is connected to the same hot and cold water mixing valve 21 via a water supply solenoid valve 53 and a water supply pipe 23. The purified water supply port 61 is connected to the water inlet of the purified water cartridge 63 via a purified water supply solenoid valve 54 and a purified water supply pipe 62.

[0024] The hot and cold water mixing valve 21 has a configuration known per se, and can control (operate) the flow rate adjustment and temperature adjustment using a single lever cartridge. Specifically, hot water is supplied via the hot water supply pipe 22, water is supplied via the water supply pipe 23, and after being mixed to have a desired flow rate and temperature according to the position and orientation of the single lever cartridge, water is discharged via the water discharge pipe 24 and the water supply hose 25.

[0025] The water supply hose 25 is connected to the water outlet pipe 24, and by passing through the hose spacer guide 26 fixed to the water outlet pipe 24, its movement in the space below the kitchen sink is restricted. Also, below the hose spacer guide 26, a stopper 27 is attached to the water supply hose 25 to limit the amount of the water supply hose 25 that can be pulled out.

[0026] At the connection part between the water outlet pipe 24 and the water supply hose 25, a raw water / purified water branch fitting 65 is provided, which is connected to the water outlet of the water purification cartridge 63 via the purified water outlet pipe 64.

[0027] The spout of the faucet device 1 of the present embodiment has a substantially "cross"-shaped base end portion 10 having a right-side (one side) protruding portion and a left-side (the other side) protruding portion, a flow control and temperature control operation lever 20 (an example of a flow control operation portion) provided on the right-side (one side) surface of the right-side (one side) protruding portion of the base end portion 10, and a rotating portion 30 (including a water discharge head 36 to be described later) rotatably provided with respect to the base end portion 10 on the upper surface side of the base end portion 10. The upper portion of the rotating portion 30 is an extending portion 30e extending in the horizontal direction.

[0028] The faucet device 1 is fixed to the rear side of the kitchen sink at the base end portion 10. Inside the right-side (one side) protruding portion of the base end portion 10, a hot and cold water mixing valve 21 is accommodated.

[0029] The hot and cold water mixing valve 21 is a single lever cartridge valve, and its single lever portion serves as the flow control and temperature control operation lever 20 (an example of a flow control operation portion).

[0030] (Rotating portion 30) At the extending portion 30e which is the upper portion of the rotating portion 30, near its tip portion, one water discharge port 41 for soft water discharge is provided. Also, a plurality of water spraying holes 42 for water broom water discharge are arranged in a matrix on the base end side with respect to the water discharge port 41.

[0031] FIG. 2 is an explanatory diagram showing the first water discharge state (soft water discharge) of the faucet device 1 of the present embodiment, and FIG. 3 is an explanatory diagram showing the second water discharge state (water spraying water discharge) of the faucet device 1 of the present embodiment.

[0032] The first water discharge state (soft water discharge) shown in FIG. 2 and the second water discharge state (water spraying water discharge) shown in FIG. 3 can be arbitrarily switched by manually rotating the rotary switch 43 at the tip of the extension portion 30e.

[0033] FIG. 4 is an explanatory diagram of the pull-out function of the faucet device 1 of the present embodiment. As shown in FIG. 4, the tip side of the extension portion 30e of the spout of the faucet device 1 of the present embodiment is a water discharge head 36 that can be pulled out from the appearance member 31 of the rotating portion 30. And the water supply hose 25 is inserted into the appearance member 31 and connected to the water discharge head 36.

[0034] (Spray holes 42) FIG. 5 is a schematic perspective view of the water discharge head 36 (a part of the spout) of the present embodiment, and FIG. 6 is a schematic cross-sectional view of the water discharge head 36 of the present embodiment.

[0035] As shown in FIG. 5, the spray holes 42 of the present embodiment are arranged in a matrix in the extending direction of the water discharge head 36 (spout) and the left-right direction perpendicular to the extending direction (about 18×5 rows. Exactly, 18 (leftmost row) + 19 + 20 (central row) + 19 + 18 (rightmost row)).

[0036] And as shown in FIG. 6, inside the water discharge head 36 (spout), a water spraying space 44 communicating with each end on the inner side of the plurality of spray holes 42 is provided. Further inside the water spraying space 44, a water spraying inner space 46 is provided through a plurality (5 in one row in this example) of outflow holes 45. Each outflow hole 45 is, for example, φ3.

[0037] Also, on the proximal end side of the water discharge head 36 (spout), a water supply passage 48 connected to the water supply hose 25 is provided, and the water supply passage 48 and the rear space 46 for water spraying are communicated by a communication flow path 47. The flow path configuration of this part is the same as that of the prior art, and the communication flow path 47 is configured to turn back from the distal end side to the proximal end side inside the water discharge head 36 (spout).

[0038] However, the communication state between the communication flow path 47 and the rear space 46 for water spraying can be arbitrarily blocked by manually rotating the rotary switch 43 at the distal end of the extension part 30e. When the communication flow path 47 and the rear space 46 for water spraying are blocked, the communication flow path 47 and the water discharge port 41 are communicated (this switching configuration is also the same as that of the prior art).

[0039] Also, as shown in FIG. 6, in the water spraying space 44, a collision wall 49 is provided at a position intersecting the extension line of each of the five outflow holes 45. In the present embodiment, the collision wall 49 is located directly below the five outflow holes 45 (with a gap of 2 mm in between). Thereby, the water discharged from the five outflow holes 45 collides with the upper surface (the upper surface of the central portion 49d) of the collision wall 49.

[0040] FIG. 7 is a schematic perspective view showing the collision wall 49 of the present embodiment, and FIG. 8 is a schematic side view showing the collision wall 49 of the present embodiment.

[0041] As shown in FIGS. 6 to 8, the collision wall 49 of the present embodiment has a rectangular columnar central portion 49d (width 2 mm, length in the front-rear direction 45 mm, height (thickness) 7 mm) facing the five outflow holes 45. The upper surface of the central portion 49d extends in a horizontal plane.

[0042] Also, the collision wall 49 of the present embodiment has a proximal end side arc-shaped portion 49c that continuously extends in an arc shape in a side view on the proximal end side of the central portion 49d, a proximal end side horizontal portion 49b that continuously extends in parallel with the central portion 49d on the proximal end side of the proximal end side arc-shaped portion 49c, and a proximal end side vertical portion 49a that continuously extends downward (toward the spout surface side) at a right angle to the proximal end side horizontal portion 49b on the proximal end side of the proximal end side horizontal portion 49b.

[0043] Asymmetrically (not completely symmetric), the collision wall 49 of the present embodiment has a tip-side arc-shaped portion 49e that continuously extends in an arc shape in a side view on the tip side of the central portion 49d, a tip-side horizontal portion 49f that continuously extends parallel to the central portion 49d on the tip side of the tip-side arc-shaped portion 49e, and a tip-side vertical portion 49g that continuously extends downward (toward the spout surface side) at a right angle to the tip-side horizontal portion 49f on the tip side of the tip-side horizontal portion 49f.

[0044] As shown in FIG. 6, the contour on the inner side (upper side) of the water spray space 44 of the present embodiment is defined so as to generally follow the contour of the upper surface of the collision wall 49. In the present embodiment, the contour on the inner side of the water spray space 44 is defined by a spacer member 38 disposed inside the water discharge head 36 (spout). The spacer member 38 also defines the inner water spray space 46 and the five outflow holes 45.

[0045] FIG. 9 is a schematic perspective view showing the inside of the water spray space 44 of the present embodiment, and FIG. 10 is a schematic plan view showing the inside of the water spray space 44 of the present embodiment.

[0046] In the present embodiment, each of some of the water spray holes in the central row is provided on an extension line (directly below) of any one of the five outflow holes 45. And around the end on the inner side of each of the some water spray holes, it bulges toward the water spray space 44 side to form a boss portion 42b.

[0047] In the present embodiment, in addition to the some water spray holes, for all of the remaining water spray holes 42 in the central three rows (excluding the leftmost row and the rightmost row), around the end on the inner side of each, it bulges toward the water spray space 44 side to form a boss portion 42b.

[0048] (First Photoelectric Sensor 33) The first photoelectric sensor 33 includes a first light projecting element that projects a first detection light through a first sensor window 33w (see FIGS. 2 and 3), and a first light receiving element that receives the reflected light of the first detection light projected by the first light projecting element through the first sensor window 33w. The first light receiving element is preferably arranged on the back side of the first light projecting element.

[0049] The first sensor window 33w is arranged on the surface portion facing the right side (an example of one of the left and right sides) of the extending portion 30e of the spout, and the first detection light is transmitted from the first sensor window 33w toward the right side.

[0050] (Second photoelectric sensor 13) The second photoelectric sensor 13 includes a second light projecting element that projects a second detection light through a second sensor window 13w (see FIGS. 2 and 3), and a second light receiving element that receives the reflected light of the second detection light projected by the second light projecting element through the second sensor window 13w. The second light receiving element is preferably arranged on the back side of the second light projecting element.

[0051] The second sensor window 13w is arranged on the surface portion facing the upper side of the left-side protruding portion 10p that protrudes to the left side (an example of the other side of the left and right sides) at the base end portion 10 of the spout. The second detection light is transmitted from the second sensor window 13w obliquely forward and upward (for example, at an angle of 60° with respect to the horizontal plane), behind the water discharge port 41 and the water sprinkling holes 42, and within the left-side region of the spout.

[0052] (On-off control of the water faucet device 1) The switching from water stop to raw water discharge (on-off control in the first mode) is controlled when the first photoelectric sensor 33 detects the "hand waving" of the user.

[0053] Specifically, the detection signal of the first photoelectric sensor 33 is transmitted to a controller box 55 (an example of a control device) via a harness (not shown), and a predetermined drive signal is transmitted from the controller box 55 to a hot water supply solenoid valve 52 and a water supply solenoid valve 53 via a harness (not shown) (see FIG. 1). In the present embodiment, from the viewpoint of preventing the user from being burned, the opening of the water supply solenoid valve 53 precedes the opening of the hot water supply solenoid valve 52 by a predetermined time.

[0054] The switching between raw water discharge and water stop (discharge and water stop control in the first mode) may be controlled by the first photoelectric sensor 33 detecting the user's "hand gesture" again, or may be automatically stopped by discharging raw water for a predetermined time or a predetermined amount.

[0055] The flow rate adjustment and temperature adjustment of the raw water to be discharged are controlled by the user's manual operation on the flow rate adjustment and temperature adjustment operation lever 20.

[0056] In addition, soft water discharge (see FIG. 2) and water spraying discharge (see FIG. 3) can be arbitrarily switched by manually rotating the rotary switch 43 at the tip of the extension portion 30e.

[0057] On the other hand, the switching between water stop and purified water discharge (discharge and water stop control in the second mode) is controlled by the second photoelectric sensor 13 detecting the user's "hand gesture".

[0058] Specifically, the detection signal of the second photoelectric sensor 13 is transmitted to a controller box 55 (an example of a control device) via a harness (not shown), and a predetermined drive signal is transmitted from the controller box 55 to a purified water supply solenoid valve 54 via a harness (not shown) (see FIG. 1).

[0059] The switching between purified water discharge and water stop (discharge and water stop control in the second mode) may be controlled by the second photoelectric sensor 13 detecting the user's "hand gesture" again, or may be automatically stopped by discharging purified water for a predetermined time or a predetermined amount.

[0060] In the faucet device 1 of the present embodiment, it does not have a flow rate adjustment function and a temperature adjustment function for the purified water to be discharged.

[0061] However, even during purified water discharge, soft water discharge (see Fig. 2) and water spraying discharge (Fig. 3) can be arbitrarily switched by manually rotating the rotary switch 43 at the tip of the extension part 30e.

[0062] Although not shown in the drawings, a commercial AC power supply is connected to the controller box 55. And the harness connecting the first photoelectric sensor 33 and the second photoelectric sensor 13 to the controller box 55 includes a signal line and a power supply line. Similarly, a harness (not shown) connecting the controller box 55 to the hot water supply solenoid valve 52, the water supply solenoid valve 53, and the purified water supply solenoid valve 54 also includes a signal line and a power supply line.

[0063] (Function and effect of the faucet device 1) According to the faucet device 1 of the present embodiment, since each of some of the plurality of water spray holes 42 is provided on an extension line (directly below) of any one of the five outflow holes 45, there is a concern that the flow rate of the water discharged from each of these some water spray holes may become too high. However, since the periphery of the inner end of each of these some water spray holes bulges toward the water spray space 44 side to form the boss portion 42b, the flow rate of the water discharged from each of these some water spray holes is appropriately suppressed, and the flow rate of the water discharged from all the water spray holes 42 can be made more uniform. Thereby, the generation of water splashing can be effectively suppressed.

[0064] Also, since the distance between the most proximal water spray hole and the most distal water spray hole is larger than the distance between the most left - hand water spray hole and the most right - hand water spray hole, there is a concern that a difference (bias) may easily occur in the flow rate of the water discharged between the most proximal water spray hole and the most distal water spray hole. However, according to the faucet device 1 of the present embodiment, since the flow rate of the water discharged from all the water spray holes 42 can be made more uniform, the generation of water splashing can be effectively suppressed.

[0065] Further, since the communication flow path 47 is configured to turn back from the tip side to the base end side inside the spout, there is a concern that, combined with the turbulence of the water flow in the communication flow path 47, a difference (bias) is likely to occur in the flow velocity of the water discharged from each water spray hole 42. According to the faucet device 1 of the present embodiment, however, the flow velocity of the water discharged from all the water spray holes 42 can be made more uniform, so that the occurrence of water splashing can be effectively suppressed.

[0066] Further, according to the faucet device 1 of the present embodiment, a collision wall 49 is provided in the water spray space 44 at a position intersecting the extension line of each of the five outflow holes 45. Thereby, the flow velocity of the water is also appropriately suppressed by the collision wall 49, and the occurrence of water splashing can be more effectively suppressed.

[0067] Further, according to the faucet device 1 of the present embodiment, the collision wall 49 extends toward the spout surface side at the base end side and the tip side. Thereby, the suppressing action of the flow velocity of the water by the collision wall 49 does not become excessive, and the occurrence of water splashing can be more effectively suppressed. When the collision wall 49 extends toward the back side at the base end side and the tip side, the flow velocity of the water is excessively suppressed at that portion, which is not preferable for the uniformization of the flow velocity of the water discharged from all the water spray holes 42.

[0068] (Modification) However, in the above embodiment, even when the collision wall 49 is removed, the presence of the boss portion 42b can uniformize the flow velocity of the water discharged from all the water spray holes 42 to some extent. Therefore, at least at the time of filing the present application, the form in which the collision wall 49 is removed is also included in the scope of the present invention.

[0069] Further, when the collision wall 49 is provided, even when the water spray hole 42 is not on the extension line of any of the five outflow holes 45 (the positions of the water spray hole 42 and the outflow hole 45 are shifted in plan view), it has been confirmed that the presence of the boss portion 42b can achieve the effect of uniformizing the flow velocity of the water discharged from all the water spray holes 42.

[0070] Incidentally, the effect of reducing the flow velocity of the water discharged from the water spray holes 42 increases as the height of the boss portion 42b increases, and decreases as the height of the boss portion 42b decreases. Also, the effect of reducing the flow velocity of the water discharged from the water spray holes 42 increases as the R of the inner and outer peripheral upper edges of the boss portion 42b decreases, and decreases as the R of the inner and outer peripheral upper edges of the boss portion 42b increases. A taper (C) may be provided instead of R.

[0071] Also, in the above embodiment, the hole diameter of the boss portion 42b was the same as the hole diameter of the water spray holes 42. However, the effect of reducing the flow velocity of the water discharged from the water spray holes 42 increases as the hole diameter of the boss portion 42b decreases, and decreases as the hole diameter of the boss portion 42b increases.
