Description

[Detailed Description of the Invention] The present invention relates to a faucet used in a kitchen or the like, and particularly to a faucet such as a band sprayer whose water discharging body can be pulled out from the main body.

Hitherto, various structures of this type of faucet have been known, such as the faucet shown in FIG. 1 of Japanese Utility Model Publication No. 49-7975.

To explain what is shown in FIG. 1, there is a first water discharging body e1 which is rotatably attached to the main body A' and is used, for example, when storing water in a water tank, and a hose 32 which is separately attached to the main body A'.
The second water discharging body e2 is connected to the second water discharging body e2 so as to be freely drawn out through the second water discharging body e2, and is used, for example, when washing tableware.

Therefore, this one is the first water discharging body e1 or the second water discharging body e2.
A switching valve 51 is required in order to discharge from one side of the main body A', and the operation of the switching valve 51 is troublesome, and the structure becomes complicated, increasing costs.
The hole 52 is required to pass the hose 32' through the hole 52, which is difficult to construct, and the receiver on which the second water discharging body e2 is placed also requires a tool, which further increases the cost.

The purpose of the present invention is to solve the above-mentioned problems and to simplify operation by eliminating the need for a switching valve, as well as to simplify construction and reduce costs.

The basic structure of the present invention is that an opening is provided in a rotating body rotatably attached to the main body, and a water discharging body connected to an outflow part via a hose is attached to this opening so as to be freely inserted and removed. By interposing a synthetic resin bushing with a retaining part between the base of the body and the opening, the rotation of the water spouting body is prevented when the water spouting body is attached. In addition, the water discharging body can be pulled out from the mounting part to wash dishes, etc., for example.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

This embodiment shows a case where the faucet is a mixer faucet for hot and cold water.

That is, as shown in FIGS. 2 and 3, the main body A is provided with inflow parts 1 and 2 for water and hot water and an outflow part 3 for mixed water. , a fixed plate 4 fixed in the main body A and an operating part a provided on the upper part of the main body A in sliding contact with the fixed plate 4.
A valve part is provided with a movable plate 5 that is movable by the operation of the fixed plate 4 and the movable plate 5, and the mutual position of the fixed plate 4 and the movable plate 5 determines the communication between the inflow part 1.2 and the outflow part 2 and the mixing ratio of water and hot water. It is designed to adjust.

Further, a cylindrical portion C is screwed onto the lower circumferential surface of the main body A, and the cylindrical portion C
has a threaded part 6 on the outer periphery of the upper part to be screwed onto the main body A, a flange part 7 projecting horizontally outward slightly below the threaded part 6, and a nut member 8 threaded on the outer periphery below the flange part 7. Each nut member 8 is provided with a threaded portion 9 to be attached, and the nut member 8 is inserted into an opening 10 formed on the mounting surface B1, for example, a counter of a sink, and screwed and tightened to the threaded portion 9 from the back side of the mounting surface 2. It is clamped and fixed to the mounting surface B by the flange portion 7 and the flange portion 7 in a non-rotatable manner.

Reference numeral 53 denotes a gasket interposed between the lower surface of the collar portion 7 and the upper surface of the mounting surface B, and between the nut member 8 and the lower surface of the mounting surface B.

When the main body A stands upright on the mounting surface B, an opening 11 is formed in approximately the front half of the drawing with an appropriate width left vertically, and a rotating body d is rotatably fitted to the outer periphery.

The rotating body d has a cylindrical base portion 12 with a slightly larger diameter than the main body A.
A cylindrical mounting part 13 is connected to the inside of the base part 12 and extends obliquely upward from the bottom of the base part 12.
2 is rotatably fitted into the outer periphery of the main body A and placed on the flange 7 of the cylindrical portion C, and the mounting portion 13 communicates with the opening 11 on the periphery of the main body A.

Further, the rotating body d has a screw 14 screwed onto the lower circumferential surface thereof, and is engaged with a guide groove 15 recessed in the outer circumferential surface of the partial main body A protruding toward the inner circumferential surface side.

The guide groove 15 is formed to extend approximately 1800 degrees in the circumferential direction of the main body A, and therefore the rotation angle of the rotating body d is restricted to approximately 180 degrees.

The distal end of the mounting portion 13 is formed with an opening 16 whose inner diameter is an appropriate width-diameter, and this opening 16 has an opening edge, that is,
A notch 17 that is a concave cutout in a part of the upper edge and a locking step 18 that has a slightly larger diameter at the lower part of the inner periphery are provided, and a bushing 19 is mounted inside this opening 16. .

The bushing 19 is made of resin, specifically polyacetal resin, into a cylindrical shape having an outer diameter that is the same as the inner diameter of the opening 16, and has a locking part 21 that projects outwardly at the upper end of the cylindrical part 20. A projection 22 is provided on the lower surface of the locking portion 21 to engage with the notch 17 of the opening 16. This prevents rotation of the opening 16 and the bushing 19, and also serves to position the bushing 19.

Further, the outer circumferential surface of the cylindrical portion 20 is provided with a pair of claw portions 23 protruding outwardly and a notch 24 cut out from the lower end at positions corresponding to the locking step portions 18 and facing each other. The claw portion 23 is locked to the locking step portion 18 by utilizing the elasticity of the locking step portion 18.

This notch 24 is provided so that when the bushing 19 is attached to the opening 16, the cylindrical portion 20 is deformed when the claw portion 23 is pressed against the opening 16.

Therefore, the bushing 19 can be easily attached to the opening 16.

Furthermore, the peripheries of the notches 24 protrude in parallel from the inner circumferential surface of the cylindrical portion 20 to form retaining portions 25a.

On the other hand, a water inflow pipe 26, a hot water inflow pipe 27, and a mixed water outflow pipe 28 are connected to the water and hot water inflow part 1゜2 and the mixed water outflow part 3 in the main body A, respectively. 27.2
The other end of 8 protrudes outside the main body A through the cylindrical portion C, and the water inflow pipe 26 and the hot water inflow pipe 27 are connected to a water supply source and a hot water supply source (not shown) via check valves 29, respectively, to supply mixed water. The outflow pipe 28 communicates with a hose 32 via an intake valve 30 and a check valve 31.

The hose 32 has a flexible tube 33 covering its entire length around its outer periphery, and the tip thereof is connected to a cylindrical portion C.
It extends into the main body A again through the opening 17 on the circumferential surface of the main body A, and is connected to the water spouting body e through the mounting part 13 of the rotating body d, and this water spouting body e is attached to the mounting part 13, that is, the bush 19, so that it can be freely inserted and removed. It is composed of a nose spray 34.

Note that the hose 32 has a length sufficient to allow the hand spray 34 to be pulled out from the mounting portion 13 and used.

The hand spray 34 consists of a grip part 35 formed in a cylindrical shape and a discharge part 36 integrally formed at the tip thereof, and the discharge part 36 has channels 37 and 38 for concentrated water discharge and water sprinkling, respectively. These flow paths 37 and 38 can be selectively spouted with concentrated water or sprinkling water using a switching valve 40 operated by a handle 39 protruding above the discharge part 36, but it is not always possible to spout water in a plurality of ways. You don't have to worry about getting the state.

The base 41 of the grip part 35 has a threaded part 49 on its outer periphery into which a cap nut 42 is screwed, and a small diameter part 45 below the threaded part 43 into which a hose fitting 44 is inserted. The hose fitting 44 is fixed to the base 41 by fixing the inner circumference of the lower end and the outer circumference of the upper end of the hose fitting 44 by screwing or the like, and by screwing the inner circumference of the upper end of the cap nut 42 into the threaded portion 49.

The hose attachment fitting 44 is formed into a cylindrical shape having an outer diameter that is the same as the inner diameter of the bushing 19, and has a retaining part on the outer circumferential surface of the lower end that engages with an engaging part 25a formed on the inner circumference of the cylindrical part 20 of the bushing 19. 25b, and the rotation of the spray 34 is prevented by the engagement of both the engaging portions 25a and 25b.

In addition, the hose mounting bracket 44 is attached to the locking edge 4 with its lower end facing inward.
6 is provided protrudingly, and a cylindrical member 42 is rotatably inserted into the inner periphery.

The lower part of the cylindrical member 47 has a small diameter and has a sawtooth outer peripheral surface to which the hose 32 is fitted, and a stepped portion 49 rotatably engaged with the locking edge 46 of the hose fitting 44 on the outer peripheral surface. The hose 32 is fixed to the cylindrical member 47 with the provided tightening ring 49.

Therefore, the cylindrical portion 47 and the tightening ring 49 are rotatable within the hose fitting 44, and the hand sprayer 34
and hose 37 are mutually rotatable.

Therefore, when the hand sprayer 34 is pulled out and used, it is convenient that the hand sprayer 34 can be freely rotated, but it is not necessarily necessary to make the hand sprayer 34 freely rotatable with respect to the hose 32. Also good.

For tightening, a nut 50 is screwed onto the inner periphery of the ring 49 below the stepped portion 48 to fix the end of the flexible tube 33.

The present invention can be modified in various ways.

For example, in this embodiment, a synthetic resin bushing is attached to the inner circumferential surface of the opening of the rotating body, but the bushing may not be attached to the opening but may be attached to the outer circumferential surface of the base of the water discharging body.

In this case, the retaining portions are provided on the inner peripheral surface of the opening and the outer peripheral surface of the bush.

Furthermore, bushings can be provided on both the inner circumferential surface of the opening and the outer circumferential surface of the base.

Furthermore, the synthetic resin bushing may be attached using elasticity, or may be screwed onto the opening or the base, bonded with adhesive, or screwed.

Furthermore, the engaging portion may be formed of a polygonal surface such as a quadrangular surface or a hexagonal surface, or may be formed of a spline, in addition to opposing parallel surfaces.

Since the present invention has the above configuration, it has the following advantages.

■ An opening is provided in the rotating body that is rotatably attached to the main body, and a water discharging body connected to the outflow part via a hose is attached to this opening so that it can be inserted and removed, and the connection between the base of the water discharging body and the opening is established. Since a synthetic resin bushing with an engaging part is interposed in between, when the water discharging body is mounted on a rotating body, the engaging part prevents the water discharging body from rotating, and water can be spouted in a stable state. Water can be discharged by pulling out the water discharging body from the opening, and operation is simple without requiring a switching valve. Also, construction is easy as there is no need for a hole for drawing out a hose on the mounting surface.

Moreover, when the water discharging body is attached to the opening, the bushing absorbs the impact, thereby preventing damage to the water discharging body and generation of noise.

Furthermore, the water discharging body does not rust on the opening and can be inserted and removed smoothly.

In addition, the structure is simple without requiring a switching valve, the construction is easy, and the receiver does not require any tools, all of which result in low cost.

■ The fact that the main body is equipped with the valve part, operation part, etc., and the water spout is attached to the main body so that it can be inserted and removed freely makes the whole unit compact and requires only a small area on the mounting surface.
