Description

[Detailed Description of the Invention] (Field of Industrial Use) The present invention relates to a spout for water spout installed near a bathtub, a washbasin, or the like.

More specifically, the present invention relates to a spout for discharging hot water from a spout in a waterfall shape for the purpose of providing a decorative effect such as natural pouring of hot water.

(Prior Art) Conventionally, as a spout of this type, the actual spear 55-4003
Nos. 8 and 59-27272 are known.

In these conventional devices, the water outlet is opened in a wide and slender slit shape, and a front descending portion is provided to direct the water outlet downward, and a flow path connecting the inflow port and the water outlet is bent into an L shape or the like. In order to improve drainage when water is stopped, a wall or weir that reduces the water passage diameter is provided in the flow path in front of the front descending part to facilitate the formation of a water film on that part. .

The wall and the weir are integrally formed with the main body of the water spout.

(Problems to be solved by the invention) As described above, in the conventional water spout, since the wall or the weir that is provided in the flow path and reduces the water passage diameter is formed integrally with the main body, It is difficult to form the height freely.

Especially when the spout is a cast product, there is a manufacturing upper limit in order to reduce the flow width dimension of the flow path by providing a weir etc. in the flow channel, and in the above conventional spout spout the weir upper end and this It is difficult to form the gap between the inner wall surface of the flow passage and the wall surface facing each other to an optimum width, and the surface of the weir etc. has a rough casting surface, but it is formed integrally with the main body and provided in the flow passage. It is difficult to cut or polish the surface so that the rough surface of the weir disturbs the flow and makes it difficult to obtain a clean discharge state.

The present invention has been made in view of the above problems of the prior art, and the object of the present invention is to improve the flow passage width in the weir portion in a spout having a weir that reduces the water passage diameter in the flow passage. This is to make it possible to form the optimum width, and also to facilitate machining such as cutting and polishing of the surface of the weir.

(Means for Solving the Problem) In order to achieve the above-mentioned object, a water spout of the present invention comprises a water discharge port opened in a wide and elongated slit shape, and a flow path connecting the inflow port to the water discharge port. In a water discharge spout that bends a water stream 90 ° and discharges downward, a weir portion that is configured as a separate member from the main body and is assembled to the main body is provided in the middle of the flow path, and the water contact of the weir portion is provided. The surface is formed into a curved surface. The main body of the water spout is formed by casting. Further, the water flow conversion wall for bending the water flow by 90 ° and the weir portion are integrally formed, and are formed separately from the main body of the spout.

(Operation) In the spout having the above-described structure, since the weir portion is formed by a member different from the main body, the height and size of the weir portion are subject to technical restrictions in casting the spout body. It can be formed freely without any need, and it becomes possible to optimally configure the gap width between the weir portion and the inner wall surface of the flow path facing it.

Further, the surface of the weir portion can be freely cut and polished before it is attached to the spout body.

In addition, since the water flow conversion wall and the weir are integrally formed, and these are formed separately from the water spout,
From the opening provided in the main body for attaching these to the main body of the water discharge spout, it is possible to process the flow path surface of the portion corresponding to the upper side of the dam portion.

(Example) Hereinafter, the Example of the water spout which concerns on this invention is described based on drawing.

In this embodiment, the water spout A is shown installed side by side with the operation cock C on the upper surface of the rim portion of the bathtub B.

The water spout A is entirely assembled and formed by a cast molding portion A1 and a synthetic resin forming portion A2, and the casting molding portion A1 constitutes a main body a of the spout A including a rising portion 1 and a horizontal portion 2. ing.

The rising portion 1 has an inflow port (not shown) at the lower end and is connected to hot water, a water supply pipe or the like at the inflow port.
Fixedly erected on the upper surface of the rim.

The horizontal portion 2 communicates with the rising portion 1, and the rising portion 1
Is formed so as to project horizontally toward the inside of the bathtub B.

A flow path b communicating with the inflow port is internally provided in the rising portion 1 and the horizontal portion 2.

On the other hand, the synthetic resin molded portion A2 is provided with a metal frame portion 9 made of stainless steel or the like for protecting the surface, and can be attached by a screw 8 to an attachment portion 10 provided in an opening on the lower surface near the tip of the horizontal portion 2 of the main body. ing.

The synthetic resin molded part A2 has a corner part 3 and a front lower part.
4, the weir portion 6 is formed.

The corner portion 3 has a flow path b extending horizontally in the horizontal portion 2 and a bathtub B.
The angle is changed to the inner downward direction of the channel, and is formed so that the flow path b is blocked and the upper and lower portions abut on the upper surface of the flow path b.

The front lowering portion 4 is connected to the flow path b of the horizontal portion 2 via the corner portion 3.
And is vertically formed toward the bottom of the bathtub B.

A water outlet 5 is opened at the lower end of the front-down portion 4, and the water outlet 5 is formed in a wide and elongated slit shape.

Further, the weir portion 6 is formed on the synthetic resin forming portion so as to project from the bottom surface of the flow channel b into the flow channel b before the front falling portion 4.
The water flow diameter is reduced by this weir portion 6, and the lower water flow contact surface 7, which is the inner surface of the inside of the corner portion 3, is formed in a curved shape by the highest portion thereof. The sudden and compulsory change in the water direction is alleviated to prevent the air trapping phenomenon from the water discharge port 5.

In this way, the weir portion 6 forms a portion in which the diameter of water flowing through the hot water is reduced. Therefore, when the water is stopped, the water pressure of the residual water on the supply side (hot water remaining on the discharge side of the water shutoff valve) is reduced. On the contrary, the air pressure for forming the water film on the water discharge port 5 is concentrated in this portion and is easily applied. Furthermore, the front falling part 4
The residual water on the supply side is physically blocked by the weir portion 6 formed on the inner lower side of the front side. Therefore, the natural outflow of residual water on the supply side is prevented. Therefore,
Good drainage when water is stopped.

In this embodiment, both width portions 4'of the front falling portion 4 are provided.
Is formed in a slanted shape toward the outside, and the water discharge port 5 is formed in a taper shape that spreads downward, thereby preventing the water discharge form from becoming a tapered shape.

(Effect) Since the present invention is configured as described above, it has the following effects.

(1) Since the weir portion that bulges in the flow path and narrows the water passage diameter is configured as a separate member from the main body and is assembled to the main body,
It is possible to freely form the degree of protrusion, and even with a spout in which the main body is formed by casting, it is easy to form the gap between the upper end of the weir and the inner wall surface of the flow path facing the weir to have an optimum width.

(2) Since the weir part is composed of a member separate from the main body, it is possible to finish the casting surface of the weir part by cutting or polishing before assembling to finish the surface smooth without disturbing the flow. , You can get a clean water discharge.

(3) Since the weir portion is formed as a separate member from the main body, the lower side of the corner portion where the flow path changes from the horizontal direction to the downward direction as compared with the case where the weir portion is integrally formed with the main body of the cast product. It is possible to form a curved surface of the water contact surface of the caster with a small degree, and from the corner to the spout even if the length of the front descent is the same as that when the weir is integrally formed with the main body of the cast product. It is possible to adjust the flow of discharged water by increasing the distance.

(4) Since the upper surface of the weir, that is, the water contact surface of the weir, is a curved surface, when the water flow changes its flow direction from the horizontal direction to the vertical direction by 90 °, the weir does not pass through. Due to the curved shape of the water contact surface, sudden and forcible conversion is mitigated, and the air trapping phenomenon is prevented from the water outlet, so that water is discharged in a clean waterfall shape without turbulent flow.

(5) Since the water flow conversion wall for bending the water flow by 90 ° and the weir portion are integrally formed and formed separately from the water discharge spout, they are attached to the main body of the water discharge spout to be attached to the main body. By using the provided opening portion, it is possible to easily process the flow path surface of the portion corresponding to the upper part of the weir portion, and the surface can be smoothed to prevent turbulent flow.
