DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-lever mixing faucet in which a single lever handle is used to control spouting / stopping water and water temperature, and more particularly to a single-lever mixing faucet having an improved outer shell. .

[0002]

2. Description of the Related Art A conventional example of a single lever mixing faucet will be described with reference to FIG.

A substantially cylindrical pedestal 14 is inserted into a faucet mounting hole 12 of a top plate 10 of a sink. On this pedestal 14,
Water holes (not shown), hot water holes 16 and mixed water holes 18
Are drilled. A fixed disk 24 is installed above the pedestal 14 via a bottom cover 22 of the valve housing 20, and a movable disk 26 is slidably superimposed on the fixed disk 24.

In the housing 20, a substantially cylindrical casing 28 is disposed so as to hold the fixed disk 24 and the movable disk 26. The housing 20 is a screw 3
It is fastened to the base 14 by 0. This screw 3
The head of 0 protrudes upward from the upper surface of the housing 20.

The upper part of the casing 28 is an inward flange. A horizontally rotatable rotation holder 34 is arranged so as to slide on the upper surface of the flange. A lever arm 36 is swingably supported by the rotary holder 34 via a horizontal support shaft 38. The lower end of the lever arm 36 is a disc top cover 4 integrated with the movable disc 26.
The upper end is fixed to the boss 42a of the lever handle 42 with a screw 44.

[0006] A decorative cap 46 for covering the valve housing 20, the rotary holder 34 and the lever arm 36.
Is arranged above the pedestal 14.

The single lever mixing faucet is fixed to the top plate 10 by screwing a nut 48 into a male screw engraved on the outer periphery of the pedestal 14. A water supply pipe (not shown), a hot water supply pipe 50, and a mixed water outflow pipe 52 are connected to the water hole, the hot water hole 16, and the mixed water hole 18 of the pedestal 14.

The fixed disk 24 is provided with a water passage hole (not shown), a hot water passage hole 54, and a mixed water passage hole 56 vertically extending therethrough. On the lower surface of the movable disk 26, a water passage hole and a hot water passage hole 52 are formed.
A concave portion 58 is provided for communicating with the second member.

By sliding the movable disk 26,
By changing the communication state of the recesses 58 between these holes, the water discharge amount and the water discharge temperature are changed. That is, by rotating the lever handle 42 in the up-down direction, the movable disk 26 advances and retreats in the left-right direction in FIG. 3, and water discharge and water stoppage (including flow rate adjustment) are performed. By rotating the lever handle 42 in the left-right direction, the movable disk 26 is rotated in a direction perpendicular to the paper surface of FIG. 3, the mixing ratio of water and hot water is changed, and the water discharge temperature is adjusted.

SUMMARY OF THE INVENTION The present invention relates to a cosmetic
Single-lever mixing faucet that can position the pump in the circumferential direction
Is provided.

[0011]

SUMMARY OF THE INVENTION A single lever mixing faucet according to the present invention is slidably overlapped with a pedestal having a water hole, a water hole and a mixing water hole formed therein and fixedly attached to a top plate of a sink. A movable disk and a fixed disk, and a valve housing disposed above the base, a lever handle for operating the movable disk disposed above the valve housing, and a makeup surrounding the valve housing. in single lever mixing faucet comprising a cap, before SL are fixed mounting the valve housing to said base by screws penetrating from the upper end surface of the valve housing to the lower end face, the head of the screw is the valve housing A stopper projecting upward from an upper end surface of the cap and engaging with a head of the screw to prevent rotation of the decorative cap is provided on an inner peripheral surface of the decorative cap. It is characterized in that the piece is protruded.

[0012]

In the single lever mixing faucet of the present invention ,
Circumferentially allows the positioning of the reduction粧cap.

[0013]

1 is an overall sectional view of a single-lever mixing faucet according to an embodiment, FIG. 2 is an enlarged sectional view of the essential part, and FIG. 3 is a perspective view showing an engagement relationship between a decorative cap and a valve housing. It is sectional drawing.

In the present embodiment, unlike the conventional pedestal 14, the pedestal 14A does not have a circling wall.
The upper surface of A is flat as a whole.

A valve housing 20 is provided above the pedestal 14A.
The fixed disk 24A is installed via the bottom lid 22A of
A movable disk 26A is slidably superimposed on the fixed disk 24A.

The rotary holder 34A which can be horizontally rotated so as to slide on the lower surface and the inner peripheral surface of the flange portion of the casing 28A.
Is arranged. A lever arm 36B is swingably supported by the rotary holder 34A via a horizontal support shaft 38. The lower end of the lever arm 36 is
6A is inserted into the recess of the disk top cover 40A integral with the disk top cover 6A. The disk top cover 40A is provided with a water hammer absorber.

The valve housing 20, the rotary holder 34A
A synthetic cap 46A made of synthetic resin for covering and hiding the lever arm 36A extends downward so as to also surround the side peripheral surface of the pedestal 14A. A stopper piece 62 that engages with the head of the screw 30 is projected from the inner surface of the decorative cap 46A.

In this embodiment, as shown in FIG. 3, three screws 30 are provided, and three sets of stopper pieces 62 are also provided.

The notch 6 in the chord direction is formed on the side peripheral surface of the base 14A.
4 is provided, and a projection 66 engaging with the notch 64 is provided on the lower inner peripheral surface of the decorative cap 46A. The engagement between the projection 66 and the notch 64 causes the specific stopper piece 62 to engage only with the specific screw 30, and the circumferential position of the decorative cap 46A is always uniquely determined with respect to the base 14A. It has become.

The other construction is the same as that of the prior art, and the same reference numerals indicate the same parts.

In the single-lever mixing faucet having the above-described structure, water is discharged and water is stopped (including flow rate adjustment) by rotating the lever handle 42 in the vertical direction. By turning the lever handle 42 in the left-right direction, the water discharge temperature is adjusted.

In this single lever mixing faucet,
Positioning of the makeup cap 46A in the circumferential direction can be performed.
Also, the circumferential direction of the makeup cap 46A is uniquely determined.
You. Therefore, the label is placed at the front position of the makeup cap 46A.
To indicate the front direction of the single lever mixing faucet
It is also possible.

Furthermore, since In the single lever mixing faucet of this, the decorative cap 46A is extended downward to surround also the side peripheral surface of the pedestal 14A, cosmetic caps 4
The seam between the 6A and the pedestal 14A is not exposed on the faucet side peripheral surface, so that the appearance is improved and the seam is not attached to this seam. The water on the upper end surface of the pedestal 14A is
Flows out between the outer peripheral surface of the base and the inner peripheral surface of the decorative cap 46A, so that water does not accumulate on the upper surface of the pedestal 14A.

In the above embodiment, the upper surface of the pedestal 14A is entirely flat. However, in the present invention, it is only necessary that the upper surface of the pedestal 14A be constructed so that water does not accumulate on the upper surface of the pedestal 14A. The peripheral portion may be at a lower level than the central portion.

[0025]

As described above, according to the present invention, single lever mixing faucet of the present invention can be a circumferential direction of the reduction粧cap constant.
