Further, an LED 6 (light source) is provided inside the spout member 4 in order to irradiate the spray water with light at the timing when the spray water is discharged from the spray nozzle 440. The LED 6 is configured to irradiate light to the outside through an LED window 60 (light transmitting window) provided on the surface of the spout member 4. At this time, a drainage flow path 62 communicating with the outside is provided between the LED window 60 and the LED 6. As a result, even when the spray water discharged from the spray nozzle 440 collides with the object to be cleaned to generate water splash and water enters the spout through the spray port 44, it is indicated by an arrow. As described above, the water can be drained to the outside of the spout through the drainage channel 62.

Further, a drain hole 64 is provided on the upstream side of the spout member 4 with respect to the LED window 60. As shown by the arrow in FIG. 4, even when the spray water discharged from the spray nozzle 440 collides with the object to be cleaned and the water splash generated enters the inside of the spout through the drainage flow path 62. It becomes possible to drain water from the drain hole 64.

The spray port 44, the LED window 60, and the drain hole 64 communicate with each other inside the spout member 4. Therefore, as described above, it is configured so that water can be discharged from the other holes to the outside of the spout regardless of which hole the water enters. Then, in order to prevent water from entering into the upstream side of this space and leaking to the bottom of the counter via the spout member 4, an inundation prevention means 66 is provided upstream of this space. ..

The pedestal member 2 includes a flange portion 29 mounted on the upper surface of the counter 10. Then, as described above, the fixing member 26 is assembled from below with respect to the threaded portion 242 of the mounting pipe 24, and the counter 10 is sandwiched between the lower surface of the flange portion 29 and the fixing member 26 via the washer 262. It has a fixed structure.

FIG. 5 is a perspective view of the vicinity of D as viewed from below. The pedestal member 2 including the flange portion 29 described above is covered from above by the cover member 8. The pedestal member 2 and the cover member 8 both have through holes 22 and 82 communicating with each other in the central portion thereof, and the spout member 4 is inserted into the through holes 22 and 82. The spout member 4 is provided with a horizontally long rotation restricting groove 46 on its side surface. Then, the pedestal member 2 is fixed by the rotation restricting member 28 inserted into the rotation restricting groove 46 through the insertion hole 244 provided in the mounting pipe 24 so as not to come out upward.

The rotation regulation groove 46 has a width longer than that of the rotation regulation member 28. Therefore, the rotation restricting member 28 is held so that the spout member 4 can rotate in the range from one end of the rotation restricting groove 46 to the opposite end. At this time, the rotation range of the spout member 4 can be widened by increasing the width of the rotation regulation groove 46, and conversely, the rotation range of the spout member 4 can be narrowed by shortening the width of the rotation regulation groove 46. become able to do.

Further, the rotation restricting member 28 includes a pair of locking claws 282, and the height Ha from one end to the other of the locking claws 282 is formed to be slightly larger than the vertical height Hb of the insertion hole 244. ing. As a result, when inserting from the outside, the locking claws 282 are bent toward the side close to each other and inserted, and after passing through the insertion hole 244, they return to the base and are fixed by a so-called snap fit.

Further, the rotation restricting member 28 is provided with a slope 284 on the outer peripheral direction side thereof. Even if the rotation restricting member 28 is loosely inserted and is in a so-called half-turned state, if the fixing member 26 is subsequently assembled with respect to the screw portion 242 from below, the fixing member 26 and the slope 284 become It will be in contact. When the fixing member 26 is further combined in this state, the upward force is converted into a force in the inner peripheral direction by the slope 284, and the rotation restricting member 28 is automatically inserted in the inner peripheral direction to snap-fit. Allows you to lead to a fixed state.

Further, by forming the spout member 4 with a pipe material, the wall thickness of the spout member can be made thin. As a result, even when the rotation restricting member 28 is fixed by the snap fit, it can be easily engaged.

Next, a method of fixing the cover member 8 will be described. FIG. 7A shows a luxury view of the pedestal member 2, and FIG. 7B shows a top view of the pedestal member 2. A plurality of elastically deformed portions 84 are formed in the vicinity of the upper end of the pedestal member 2 along the direction of the outer edge. Both ends of the elastically deformed portion 84 are supported by the pedestal member, and the central portion thereof is configured to elastically deform in the radial direction. Further, a locking projection 844 is provided near the central portion thereof.

As shown in FIG. 5, the cover member 8 is inserted from above the pedestal member 2, and the elastically deformed portion 84 is elastically deformed, so that the locking claw 86 of the cover member 8 and the locking projection 844 of the pedestal member 2 are formed. The cover member 8 is fixed by locking each other. As a result, the cover member 8 is fixed so as not to fall off upward.

Further, at this time, the rotation direction positioning means 88 included in the pedestal member 2 and the cover member 8 are in contact with each other, so that the relative rotation of the cover member 8 and the pedestal member 2 is restricted. With this configuration, it is possible to prevent the cover member 8 from rotating, disengaging the locking claw 86 and the locking projection 844, and causing the cover member 8 to fall off.

At this time, a washer 9 which is an inelastic member is provided below the elastically deformed portion 84. Since the washer 9 functions as a regulating member for regulating the downward deformation of the elastically deformed portion, when the cover member 8 is inserted from above, the elastically deformed portion is deformed downward and is destroyed. It becomes possible to suppress that it is done. Further, by using the washer as a regulating member for restricting the downward deformation of the elastically deformed portion, even when a plurality of elastically deformed portions 84 are provided along the radial direction as in this embodiment, it is simple. It becomes possible to suppress the deformation of all the elastically deformed portions 84 with one member.

Further, unlike the elastically deformed portion 84, the washer 9 is colored red. By doing so, it becomes possible to confirm at a glance whether or not the washer 9 is inserted in the assembly process, and it is possible to suppress forgetting to insert the washer 9 and the accompanying destruction of the elastically deformed portion 84. You can do it.

The pedestal member 2 and the cover member 9 are provided with O-rings 48a and 48b inside, respectively. The O-rings 48a and 48b are located between the O-rings 48a and 48b, and due to their elasticity, function as spout member holding means for holding the spout member 4. Further, by functioning as a sealing member for sealing between the spout member 4, the pedestal member 2, and the cover member 9, water applied from above is prevented from entering the inside of the counter 10. -ing
