Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a drip tray of a flushing water sprinkling part of a flush urinal, that is, a water spouting nozzle.

(Prior art) Flush urinals are mostly made of ceramics, and have a water passageway with many small watering holes called water bladders that are integrally molded on the top of the main body. It is common to wash by flushing.

To solve this problem, a water spouting nozzle devised by the present inventor (for example, Utility Model Publication No. 59-38552) is attached to the upper wall of the urinal body, and the water spout is sprayed toward the bowl surface. , the ball surface can be thoroughly cleaned with a small amount of cleaning water.

However, because the water spout nozzle is installed in the center of the upper wall of the urinal, the remaining water after spraying drips from the spout and bounces off the bottom of the ball surface, causing problems such as leaking down the hem of pants. Contains.

To deal with this, a tongue-shaped drip tray D was attached to the lower side of the spout as shown in Figure 5, but the dimensional accuracy of the ceramic urinal was affected by the variation in the reduction rate during molding. Since it is not accurate, the gap between the tip edge portion _D1 of the droplet catcher D and the ball surface _C1 is not constant. In other words, if the gap is wide, the remaining water will not flow from the tip edge to the ball surface, but will drip from the same area, and if the gap is narrow, the remaining water will flow to the ball surface, but The cleaning water being sprayed is obstructed by the tip edge and cannot flow to the ball surface directly below the tip edge, making it impossible to clean the entire ball surface.

Therefore, the gap size (approximately 1 to 3 mm) is
The relationship must be adjusted so that no drips occur and the washing water is not obstructed, which requires adjustment work in addition to installation work.

(Problems to be Solved by the Invention) The problems to be solved by the invention are useful in eliminating the occurrence of drops without requiring adjustment work, and in not interfering with the cleaning of the entire ball surface with cleaning water. is to provide.

(Means for Solving the Problems) The measures taken by the present invention to achieve the above-mentioned problems are a water spout nozzle whose spout is attached to the top wall of the urinal body with its spout facing toward the ball surface. In the droplet receiver, a droplet receiver made of a flexible elastic material, which is connected to a connection part that can be attached to the water spout nozzle and is located below the water spout, is inclined downward toward the ball surface, and the tip edge portion is the ball surface. It is characterized in that it is formed in such a manner as to reach , and its tip portion is formed in a roughly serrated shape in which drop guiding recesses and water passage recesses alternate.

(Function) The droplet receiver receives the residual water falling from the spout and guides it along the slope to the lower tip edge.

Then, the drop guiding convex part contacts or elastically presses against the ball surface, collects the remaining water flowing directly from the inclined surface part and the remaining water flowing along the edge of the water passage recess, and transfers it to the ball surface. Flow.

On the other hand, the water passage concave portion maintains a distance from the ball surface, and allows the cleaning water that is jetted from the water spout portion and flows vigorously over the ball surface portion to pass through.

As a result, the distance error with the ball surface is eliminated by the drop guiding convex part, and the remaining water does not remain on the ball surface, but is guided and flows along the same surface.The cleaning water being sprayed follows the ball surface and its flow force is reduced. The water passes through the concave portion and the entire ball surface is cleaned.

(Example) An example of implementing the present invention will be described in detail below with reference to the drawings.

In the figure _, A is a droplet catcher, and this droplet catcher A is a connection part that can be attached to a water spouting nozzle B, which is attached to the upper wall part _C2 of the urinal body C, with the spout part _B1 facing the ball surface C1. 1, and the droplet receiving part 2, which is connected to this connecting part 1 and located below the spout part _B1 , is connected to the ball surface _C1.
It is formed in such a manner that it slopes downwardly toward the ball surface, and the tip edge portion 3 reaches the ball surface, and the tip edge portion 3 is formed in a roughly sawtooth shape in which drop guiding convex portions 4 and water passage concave portions 5 alternate.

The droplet receiver A is made of the same material and is made of a flexible and elastic material such as rubber or plastic.

The connection part 1 connects the water discharge nozzle B to the urinal body C.
(Fig. 11,
(Fig. 3), or can be attached to the lower side of the water discharging nozzle B.

The droplet receiving part 2 has a width ratio slightly larger than the opening width of the water spout part _B1 , and is designed to receive all the residual water that flows down from the water spout part _B1 and guide it to the tip edge part 3. .

The drop guiding convex portion 4 on the tip edge portion 3 preferably has a sharp tip so as not to obstruct the passage of cleaning water during jetting and to reliably guide residual water to the ball surface.

The water passage recess 5 has a depth that allows cleaning water to reach the ball surface.
The dimensional relationship is set to be about 12 mm, for example, so that the water can pass through C ₁ without receiving resistance, and the valley edge is made into an arc shape with a radius of curvature of about 3 mm, so that residual water can flow through the valley edge and create a convex convexity for guiding drops. I try to make it flow into part 4.

As a result, the state in which it is installed in the water discharging nozzle B attached to the urinal main body C and communicating with the high tank (not shown) as shown in FIG. 1, and the tap water system as shown in FIGS. 3 and 4. In any state where it is incorporated into the directly connected water discharging nozzle B,
Depending on the distance error between the drop guiding convex portion 4 and the ball surface C ₁ , the drop guiding convex portion 4 is brought into contact with the ball surface C ₁ or is elastically bent to be in pressure contact with the ball surface C 1 , and the cleaning water sprayed from the water spout portion B ₁ is directed to the tip of the ball surface C 1 . The water is jetted from the edge portion 3 with the same flow rate, and any remaining water after the jetting is stopped can flow down the ball surface _C1 without leaving any remaining water.

(Effect of idea) Therefore, the present invention has the following advantages.

All you have to do is attach it to the water nozzle.
The distance error between the ball surface and the ball surface is substantially automatically corrected, and there is no need for the work of adjusting the distance.

All remaining water from the spout can flow down to the ball surface, eliminating problems such as leakage at the hem of pants.

The cleaning water jetted from the water spout can be directed to the ball surface part below the tip edge of the droplet receiving part with the same flow rate, and the entire ball surface can be cleanly cleaned.
