DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 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 of the present embodiment (here, a single lever type water discharging device), and a predetermined mounting base (a counter in a kitchen sink in this example) 1
2 is set up.

As shown in FIG. 2, a flow regulating valve 22 and a lever-type flow regulating operation section 26 for rotating a valve body 24 are provided at the distal end of the water discharge pipe 18. Valve body 24
Has a circular fitting portion 28 and a plate-shaped flow resistance portion 30 as shown in FIG. 3, and the fitting portion 28 is provided on the side surface of the water discharge pipe 18 so as to protrude. It is rotatably fitted to the inner surface of the portion 32 via an O-ring 34 in a watertight manner. Then, the plate-shaped flow resistance portion 30 protrudes into the water discharge passage 36 so as to cross the water flow in the water discharge passage 36 in the water discharge pipe 18.

The water discharge passage 36 includes a main passage 36A and a water discharge passage 36B which is bent at a right angle from the main passage 36A and reaches the water discharge opening 20.
The flow resistance portion 30 has a main passage 36A
And the rotation axis thereof protrudes in a direction intersecting the axis of the water discharge passage 36 at right angles, and is rotatably disposed.

The opening of the cylindrical portion 32 provided in the water discharge pipe 18 is closed by a cap 40. This cap 40
Has a female screw on the inner surface of the outer peripheral portion, and the female screw is attached to the cylindrical portion 32 by being screwed into a male screw on the outer peripheral surface of the cylindrical portion 32.

An insertion hole is formed in the center of the cap 40. On the other hand, a shaft portion 42 is provided in the valve body 24, and the shaft portion 42 is inserted through the insertion hole and protrudes to the outside. A polygonal (square-shaped in this example) engaging portion 44 is formed on the protruding portion, and the engaging portion 44 corresponds to the corresponding polygonal shape ( Here, it is engaged with the (square) engaging hole 46 in an integrally rotating state.

Here, the shaft portion 42 and the flow control operation portion 26 are prevented from being separated from each other by a set screw 48. The flow adjustment operation unit 26 is provided with a lever 50 in an integrally rotating state.
6 can be rotated.

In this embodiment, the valve body 24 is provided with a rotation regulating projection 52 as shown in FIG. On the other hand, at a position corresponding to the cylindrical portion 32 in the water discharge pipe 18,
As shown in FIG. 2B, an arc-shaped groove 54 is formed, into which the projection 52 enters.

In this embodiment, the valve element 24 can be rotated only within an angular range between positions where its projections 52 contact both ends of the groove 54. That is, in this example, the protrusion 52 and the arc-shaped groove 54 constitute the rotation restricting portion 56. Here, the position and the size of the projection 52 and the groove 54 are determined so that the flow rate of the water discharged from the water discharge port 20 changes from a small flow rate to a large flow rate.

In this embodiment, the positioning mechanism 57 (FIG. 2B) for positioning the valve body 24 in a plurality of stages along the rotational direction.
Reference). Reference numeral 58 denotes a positioning projection which forms a part of the positioning mechanism 57, and is provided so as to protrude axially from the end face of the valve body 24 as shown in FIG.

The positioning projection 58 has an engagement projection 60, and the engagement projection 60 elastically engages with a plurality of engagement recesses 62 provided at a predetermined pitch along the inner peripheral surface of the cylindrical portion 32. It is designed to be engaged. In this example, the engaging projection 60
Engages with the engagement concave portion 62 to determine the rotational angle position of the valve element 24, and the engagement protrusion 60 is engaged with the engagement concave portion 6
The valve body 24 is positioned at a predetermined rotation angle position with a click feeling when elastically engaging the second member 2.

The positioning mechanism 57 functions to prevent the valve element 24 from rotating from a desired angular position due to the water flow in the water discharge passage 36. As shown in FIG. 1, reference numeral 64 denotes a water discharge pipe cap attached to the distal end of the water discharge pipe 18. The water discharge port 20, the flow control valve 22, the flow control operation unit 26, and the like are provided with the water discharge pipe cap. 64.

In the water discharge device 10 of the present embodiment, the lever type flow control operation portion 26 is rotated while the main operation portion 16 is opened to the maximum flow rate, and the plate-shaped flow resistance portion of the valve body 24 is rotated. 4A, that is, when the plate surface faces the same direction as the water flow, the flow resistance to the water flow becomes minimum, and the water discharge flow rate from the water discharge port 20 becomes the maximum flow rate.

In this state, the flow regulating operation part 26 is rotated to rotate the valve element 24, and the flow resistance part 30 is brought into a state shown in FIG. 4B, that is, a state in which the flow resistance part 30 is largely inclined with respect to the direction of the water flow. At this time, the flow resistance against the water flow becomes maximum,
The water discharge flow rate from 0 is the minimum flow rate. At this time, the flow resistance portion 30 is more likely than the state shown in FIG.
The projected area with respect to the transverse section of the water discharge passage 36 increases, and the effective flow passage area in the water discharge passage 36 becomes the smallest.

By rotating the valve body 24 within the above range, the flow rate of water discharged from the water discharge port 20 can be changed almost continuously between a small flow rate and a large flow rate. Strictly, each time the engaging projection 60 of the positioning protrusion 58 of the positioning mechanism 57 engages with each of the plurality of engaging concave portions 62, the water discharge flow rate is changed stepwise in a plurality of steps.

In the water discharge device 10 of this embodiment, the flow control valve 22 provided on the water discharge pipe 18 can be operated by the flow control valve 22 without operating the main operation section 16 of the remote body 14 at every time. The water discharge flow rate from the water discharge port 20 can be adjusted only by a hand operation in the unit 26. Therefore, even when the water discharge flow rate is frequently adjusted while working in front of the sink, for example, the operation can be controlled. Can be performed extremely easily, and the workability of the operation while performing water discharge is improved. Further, according to the present embodiment, the structure of the flow control valve 22 is simple, and therefore, the flow control valve 22 can be easily provided on the water discharge pipe 18.

Also, in this embodiment, the provision of the rotation restricting portion 56 allows the water discharge flow rate to be adjusted within a predetermined range, and erroneously turns the valve body 24 to the water stop position.
It is possible to prevent an excessive pressure from being generated in the water discharge pipe 18.

In the above example, the valve element 24 is positioned in a plurality of stages in the rotational direction. However, without such positioning, the valve element 24 is continuously changed in the rotational angle position, and It is also possible to completely continuously change the water discharge flow rate from the nozzle.

Alternatively, as shown in FIG. 5, the rotational angle position of the valve element 24 can be determined in three stages of a small flow rate, a medium flow rate, and a large flow rate. In particular,
The engagement recesses 62 are provided at three positions corresponding to the small flow rate, the medium flow rate, and the large flow rate, and the engagement projections 60 of the positioning protrusions 58 are elastically engaged with any of the engagement recesses 62. , The rotation angle position of the valve body 24 is switched to three stages, and the water discharge flow rate from the water discharge port 20 is set to three of small flow, medium flow, and large flow.
It is also possible to switch between stages.

In the case of the water spouting device 10 that spouts water in the sink of the kitchen, it may be sufficient to perform spouting at three types of flow rates: a small flow rate, a medium flow rate, and a large flow rate. According to this example, the valve body 24 can be quickly rotated to the target position, and the water discharge flow rate can be quickly switched to a plurality of stages.

FIGS. 6 to 8 show another embodiment of the present invention. Also in this example, the flow regulating valve 66 and its valve element 6
A flow control operation unit 70 for rotating the nozzle 8 is provided at the tip of the water discharge pipe 18. However, in this example, the flow control operation unit 70
Is a dial-type flow control unit.

The flow control section 70 has a partially spherical surface, and its radial dimension is the same as the radial dimension of the water discharge pipe cap 64. In addition, the flow control operation unit 70
Is provided in a state where the rotation axis coincides with the axis of the main passage 36 </ b> A in the water discharge pipe 18.

As shown in FIG. 7, the valve element 68 has a circular base 72 and a plate-like flow resistance part 74 having a semicircular cross section, that is, a half cut-out cylinder. The base 72 is watertightly and rotatably fitted and held in a holding hole 76 formed in the water discharge pipe 18, specifically, the water discharge pipe cap 64 via an O-ring 34. In this example, the valve body 68 is provided with a shaft portion 78, and the shaft portion 78 is connected to the dial-type flow adjustment operation portion 70 in an integrally rotating state. In these figures, reference numeral 75 denotes a notch.

In this embodiment, as shown in FIG. 6, the valve body 68 is disposed so as to protrude into the main passage 36A with its rotation axis orthogonal to the axis of the water discharge passage 36B. . More specifically, in this example, the valve body 68 is disposed so as to protrude into the main passage 36A at the bent portion of the water discharge passage 36, and the flow resistance portion 74 is disposed so as to cover the water discharge passage 36B from above.

In the case of the water discharging apparatus 10 of the present embodiment, the main operation section 16
8A, the flow resistance portion 74 having a semicircular cross section is positioned on the upper side, and the cutout portion 75 is positioned on the lower side, as shown in FIG. 8A. In the water discharge passage 36, the flow resistance of the flow resistance portion 74 hardly occurs with respect to the water flow flowing from the main passage 36A to the water discharge passage 36B in the water discharge passage 36, and therefore, the water discharge flow from the water discharge opening 20 becomes the maximum flow.

On the other hand, as shown in FIG. 8B, when the valve body 68 is rotated by 180 ° so that the flow resistance portion 74 is located on the lower side and the cutout portion 75 is located on the upper side, the water outlet passage is provided. The flow resistance of the flow resistance portion 74 is maximum with respect to the water flow flowing into the inside 36B, and in this state, the flow rate of the water discharged from the water discharge port 20 is the minimum flow rate.

The rotation of the valve body 68 within the above range causes the flow resistance of the flow resistance portion 74 to gradually change with respect to the flow of water flowing into the water discharge passage 36B. The flow rate is varied continuously. The rotation operation of the valve body 68 is performed by rotating the dial-type flow control operation unit 70 at the tip of the water discharge pipe 18. Thereby, the rotation angle position of the flow resistance part 74 of the valve body 68 is changed.

Also in this embodiment, the flow regulating valve 66 can be constructed with a simple structure, and the water discharge pipe 18, specifically, the water discharge pipe cap 64
This can be easily provided. Further, the resistance to the water flow can be efficiently changed with the rotation of the valve body 68, and the water discharge flow rate can be adjusted simply and efficiently.

In the embodiments shown in FIGS. 6 to 8, the rotation restricting portion for restricting the rotation angle position of the valve body 68 and the positioning mechanism for positioning the rotation angle position of the valve body 68 in two or more stages. Can also be provided.

The embodiment of the present invention has been described in detail above, but this is merely an example. For example, the present invention can be applied to a water discharging device in which a main operating portion is provided on a main body and a hose extends from the main body and a shower head is provided at a tip of the hose. The invention can be configured in variously modified forms without departing from the gist of the invention.
