Description

[Detailed Description of the Invention] The present invention relates to a water spouting fitting for discharging hot water into a bathtub or the like.

Conventionally, for example, in commercial bathhouses, the width of the hot water outlet is widened so that hot water is discharged flatly into the bathtub like a waterfall, giving the appearance of an abundant inflow of hot water.

However, in this case, when the flow rate of hot water is increased or decreased, the discharge state becomes unstable and there is a drawback that the water is spouted from the discharge port in a biased manner.

The present invention provides a faucet spout fitting that can provide such a unique flat discharge state.
Regardless of the flow rate or over a wide range when the flow rate is variable, the above-mentioned unique discharge condition can be obtained.The structural feature is that a water reservoir is formed inside, and the water reservoir is An inlet is provided in the rear wall of the chamber, a wide weir is formed higher than the inlet in the front wall, and a flat and wide discharge port is formed beyond the weir.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. The figure shows a water discharging fitting attached to a hot water mixing and discharging device; 1 is a faucet; 2 is a hot water faucet;
Reference numeral 3 denotes a hot water mixing pipe that connects the outflow side of the faucet and the hot water tap, and an L-shaped bent discharge pipe 4 is connected to the middle part of the hot water mixing pipe. A water discharge fitting 5 of the present invention is provided at the tip of the discharge pipe 4. A water reservoir chamber 6 is formed inside the water discharge fitting 5, and an inlet 7 connected to the discharge pipe 4 is provided on the rear wall of the water reservoir chamber 6. The water reservoir chamber 6 has a width several times wider than the inlet 7. A wide weir part 8 is formed on the front wall of the water storage chamber 6 so that its upper surface is higher than the upper edge of the inlet 7. At the tip of the weir part 8, a flat and wide discharge port 9 is formed by curving the top wall of the water discharging fitting 5 into a beak shape and covering the weir part 8 with a predetermined water flow gap.

In the device configured in this way, hot water that has exited the faucet 1 or the hot water faucet 2 and mixed in the hot water mixing pipe 3 flows into the water reservoir chamber 6 from the inlet 7 via the discharge pipe 4.
When the force of the hot water blowing out from the inlet 7 is strong, the hot water flows through the weir part 8 which is formed higher than the inlet 7.
The energy is reduced by hitting the front wall of the Then, the hot water accumulated in the water storage chamber 6 crosses over the weir part 8 and overflows from the discharge port 9. The weir part 8 blocks the hot water that blows out at its front wall, and also expands the hot water accumulated in the water storage chamber 6 in both width directions to uniformly overflow it and discharges the hot water from the discharge port 9 in a flat shape. .

FIGS. 4 and 5 show modified examples of the water discharge fitting 5.
In the modification shown in FIG. 4, the front wall 8' of the weir part 8 is formed to be gently depressed at the center facing the inlet 7. By forming it in this way, even when the force of the hot water blown out from the inlet 7 is particularly strong, the hot water will scatter to both sides as shown by the arrows in the figure, and more water will be spouted from both ends of the outlet 9. This may be even better since it can prevent this and ensure that water is discharged uniformly over the entire width of the discharge port. In addition, for the same purpose, as shown in Figure 5, by forming the upper surface of the weir section 8 so that it is gently lowered at the middle part in the width direction, the weight of the hot water flowing on the upper surface of this weir section causes hot water to flow in the middle. It is also conceivable to make it uniform over the entire width so that it gathers.

As explained above in the embodiments, the water spouting fitting of the present invention forms a water reservoir chamber, eliminates the force of inflowing water by the weir part, spreads the inflowing water evenly, and overflows the wide weir part to discharge water. Regardless of the flow rate, a flat, flat discharge state like a waterfall can be obtained from the entire width of the flat and wide discharge port. As a result, it appears as though there is an abundance of hot water flowing in at any time, which has the effect of enlivening the mood of the bathroom.
