In the case of this water discharging apparatus, it is possible to easily drink water by discharging water upward from the water outlet.
[0003]
By the way, in the case of this water discharging apparatus, the overflow water from the upward water outlet flowed to the base end side through the water discharging part at the time of water stop, and the problem that the attachment surface of the water discharging part wets occurred.
In this case, when the mounting surface is a vertical wall surface, the water that has flowed to the base end side of the water discharge portion can flow downward along the wall surface, and the mounting surface is always wetted by the overflow water. Such a problem does not occur.
[0004]
However, if the mounting surface is horizontal or nearly horizontal, the water that has flowed to the base end side of the water discharge part accumulates on the mounting surface or remains in a wet state. Is produced.
That is, in the case of this type of conventional water discharger capable of water discharge, there is a problem that the mounting surface of the water discharge part is limited.

FIG. 7 is a comparative example for facilitating understanding of this problem. In the figure, reference numeral 200 denotes a water discharge unit, and 202 denotes a water discharge head 202 in the water discharge unit 200.
The water discharge head 202 has a water discharge port 204 and is rotatable up and down between a downward direction shown in FIG. 5A and an upward direction shown in FIG.
In the case of the water discharger 200, water can be discharged downward in the state shown in (A), and water can be discharged upward in the state shown in (B).
[0006]
In the case of this water discharge device, the portion from the front surface 208 of the water discharge head 202 to the upper surface 210 in FIG. 7A (becomes the lower surface in the upward water discharge state of (B)) is a curved surface 212 having a large curvature. When the water is stopped in the upward water discharge state shown in (B), the overflow water from the water discharge port 204 flows to the water discharge unit main body 206 through the front surface 208 and the curved surface 212, and the water discharge unit main body 206 is further passed through. If it reaches the base end side of the water discharger 200, and the mounting surface of the water discharger 200 is horizontal or nearly horizontal, it accumulates on the mounting surface or stagnates on the mounting surface. This causes a problem of deteriorating the quality of the water discharge device.

[0015]
【Example】
Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, reference numeral 10 denotes a water discharging device capable of discharging water in this example, and reference numeral 12 denotes a water discharging portion protruding upward from a counter 14 as an attachment base.
The water discharger 12 is fixedly attached to the counter 14 in a state of standing from a horizontal or substantially horizontal mounting surface 18 in the mounting hole 16 of the counter 14.
[0016]
The water discharger 12 includes a water discharger main body 20 and a water discharge head 22 on the distal end side.
The water discharger body 20 also has a curved guide tube 24 and a pedestal tube 26, and the pedestal tube 26 is screwed into the male screw tube 28 inserted through the mounting hole 16 from below the counter 14. Along with the fixing nut 30, the counter 14 is fixed to the counter 14 with the triangular packing 32 interposed therebetween.
[0017]
Reference numeral 34 denotes a slide tube that moves up and down integrally with the guide tube 24, and a hose 36 is inserted through the slide tube.
The hose 36 is inserted through the water discharge portion main body 20, specifically, the pedestal tube 26 and the guide tube 24, and the tip thereof is connected to the water discharge head 22.
The slide tube 34 slides with respect to the inner peripheral surface of the male screw tube 28 when moving up and down.
[0018]
The water discharge head 22 has a head main body 38 following the water discharge section main body 20 and a water discharge port 40 having a smaller diameter and a circular shape than the head main body 38, and is rotatable up and down with respect to the water discharge section main body 20.
[0019]
As shown in FIG. 2B, the head body 38 has a semicircular cross section of the front surface 42, and the entire front surface 42 is inclined at a predetermined angle with respect to the vertical direction. .
Strictly speaking, in the upward water discharge state shown in FIG. 2 (A), the front surface 42 is inclined to the left in the drawing with respect to the vertical direction, that is, the base end of the water discharger 12 as it goes upward from the lower end in FIG. 2 (A). The surface is inclined to the side away from the surface.
[0020]
On the other hand, in the upward water discharge state shown in FIG. 2 (A), the lower surface thereof (the upper surface in the downward water discharge state shown in FIG. 1) and the front end surface 44 have the following shape, that is, the tangent P of the front end surface 44 is the front end side. It is made into the surface which makes a downward angle with respect to the horizontal direction toward this.
In other words, the tip surface 44 is a surface that is shaped downward with respect to the horizontal direction as it advances to the tip side, and the bottom surface and the tip of the tip surface 44 drop the overflow water from the spout 40 downward, A water transfer blocking unit that blocks the overflow water from flowing to the proximal end side of the water discharge unit 12 is used.
The angle θ formed by the tangent line P can be selected as an appropriate angle at an angle of 0 ° or more with respect to the horizontal direction.
[0021]
In this example, the intersection 46 between the front surface 42 and the front end surface 44 is a curved surface (or square surface) having a radius of 5 mm or less.
The front end surface 44 is a surface having a shape that drops downward as it advances toward the front end side over substantially the entire width of the water discharge head 22. That is, the water transfer blocking portion is formed over substantially the entire width of the water discharge head 22.
[0022]
In the water discharging apparatus 10 of this example, the water discharging head 22 can be rotated up and down as described above, and water can be discharged downward from the water discharging head 22 in the state shown in FIG. 1, and FIG. The water discharge head 22 can be discharged upward by rotating the water discharge head 22 upward and performing the water discharge operation with the water discharge port 40 positioned upward.
In this case, since water is discharged upward, it is possible to easily drink water.
[0023]
Thus, when the water stop operation is performed in the upward water discharge state shown in FIG. 2A, the upward water discharge from the water discharge port 40 is stopped. At this time, the overflow water from the water discharge port 40 flows downward.
Here, in the water discharge device 10 of the present example, the lower surface and the front end surface 44 of the water discharge head 22 in the upward water discharge state in FIG. 2A are formed as surfaces that are downwardly lowered with respect to the horizontal direction. Since the front end is configured as a water transfer blocking portion, and the front surface 42 of the water discharge head 22 is inclined with respect to the vertical direction, the intersection 46 between the front surface 42 and the front end surface 44 has a radius. Since it is a curved surface or a square surface with a small curvature of 5 mm or less, when the overflow water from the spout 40 flows to the lower end of the front surface 42, it is dropped downward from there and the water that has flowed along the front surface 42 flows. Subsequently, there is no inconvenience that the horizontal or substantially horizontal mounting surface 18 is wetted by flowing along the bottom surface of the water discharger 12 to the base end side.
[0024]
In this example, the tip surface 44 is a flat surface over substantially the entire width of the water discharge head 22 and an inclined surface that is downwardly lowered with respect to the horizontal direction as it advances toward the tip side. It can also be a curved surface that falls downward as it progresses.
[0025]
3 and 4 show an example in which a protrusion projecting forward is provided on the front surface 42 of the water discharge head 22 and the protrusion is configured as a water transfer blocking portion.
Among these, the example of FIG. 3 is an example in which the front end surface 44 in the above-described embodiment is extended forward as it is, and a protrusion 48 is provided at the lower end position in FIG.
Example of one Hoes 4 (Reference example), the case of providing the projection 50 at the lower end position of the front 42 and extend above the lower surface and front end surface 44 horizontal surface and without, and which is directly forward in the horizontal direction It is an example.
[0026]
Even in these cases, the overflow water from the water discharge port 40 is dropped downward at the water transfer prevention portion by the action of the water transfer prevention portion composed of the protrusions 48 and 50, and the overflow water causes the water discharge portion 12 to be on the proximal side. It is possible to effectively prevent the attachment surface 18 from getting wet and getting wet.
[0027]
FIG. 5 shows an example ( reference example ) in which a protrusion projecting downward is provided on the lower surface of the water discharge head 22 in the upward water discharge state, and the protrusion is configured as a water transfer blocking portion.
Of these, the example (A) is an example in which a downward projection 52 is provided at the lower surface and the tip position of the water discharge head 22, and the example (B) further includes a dome-shaped projection 54 on the lower surface of the water discharge head 22. An example in the case of being provided, and an example in (C) is an example in which a downward projection 56 is provided at the rear end of the water discharge head 22, that is, at a position in contact with the water discharge unit main body 20.
[0028]
On the other hand, FIG. 6D is an example ( reference example ) in which a downward projection 58 is provided near the tip of the water discharger body 20, specifically the guide tube 24, on the lower surface of the tip of the water discharger 12.
In any of these cases, the overflowing water from the water discharge port 40 flows to the proximal end side of the water discharger 12 and wets the mounting surface 18 by the water transfer blocking part composed of the protrusions 52, 54, 56, 58. The problem can be solved.
[0029]
5 (C) and 6 (D) are examples in which the protrusions 56 and 58 have a cross-sectional mountain shape and the tip thereof is pointed, and the example of FIG. 5 (B) An example in which the protrusion 54 is a dome-shaped protrusion is shown.
Further, the example of FIG. 5A shows an example in which the protrusion 52 is a plate-like protrusion.
[0030]
Example of FIG. 6 (E) (reference example), the front end surface of the head body 38 in the water discharge head 22, i.e., in a state of protruding the disk-shaped projection 60 in the transverse direction to a position just below the water discharge port 40 in the upward spouting state This is an example of a case where this is configured as a water transfer blocking part. In this example as well, in the upward water discharge state, overflow water from the water discharge port 40 is prevented from flowing through the water discharge part 12 to the proximal end side when water stops. Therefore, it is possible to solve the problem that the mounting surface 18 gets wet by the flowing water.
[0031]
Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example , it is possible to configure the water discharger by appropriately combining the above embodiments and reference examples, and it is also possible to configure the water transfer blocking unit in various other forms than the above examples.
Furthermore, the present invention can be applied to a water discharge device in a form other than the water discharge device 10 of the above example, and the present invention can be configured in various forms without departing from the gist of the present invention.
