Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single lever type faucet comprising a faucet main body with a water discharge pipe in which a water supply channel is formed, and a faucet body detachably mounted on the faucet main body.

[0002]

2. Description of the Related Art As shown in FIG. 7, the present applicant removes a universal faucet main body 1b having a rotary operation handle 21 from a faucet main body 1a of an existing universal faucet for discharging tap water or the like. An operation lever 59 is attached to the remaining faucet main body 1a.
A single lever type faucet 1 in which a faucet main body 23 having a ceramic fixed disk 46 and a ceramic movable disk 49 is detachably mounted has been proposed (Japanese Patent Application No. 11-28970, See drawing). This single-lever type faucet 1 can operate the operating lever 5 without tightening the operating handle 21 unlike the universal faucet main body 1b.
The water stop and flow rate can be adjusted by moving the movable disk 49 by a simple operation only by turning the vertical 9 in the vertical direction, and since the disks 46 and 49 are used, the free faucet main body 1b is used. Packing 15 as in the case of
This is very useful in that water can be completely stopped by avoiding a situation in which water is leaked due to deterioration of water.

[0003]

However, as shown in FIG. 6, this single-lever type faucet 1
0, the faucet main body 1a placed and fixed on the mounting surface 22 of the washstand 21.
The length L (see FIG. 1) of the water discharge section 4 is short, and
On the extension of the mounting surface 22 or on the mounting surface 2

A water outlet 97 is provided at a downstream end, which is a leading end, and an introduction opening 97b is provided at an upstream end, which is a base end, to communicate with the vertical annular groove 94 via a water passage 91b. Reference numeral 98 denotes an annular hinge, to which the water discharge pipe 96 is connected by a connection means such as brazing through an introduction opening 97b. The hinge 98 can be prevented from coming off by a cap 102 in an annular mounting groove 101 formed in the peripheral wall portion 91, and is rotatably fitted around the central axis X. The hinge 98 has one communication hole 99 that can communicate with the vertical annular groove 94. Further, the cap 10
2 is attached to the protruding member 90 so as to cover the closing portion 92.

By pressing the base 90a of the projecting member 90 against the peripheral surface of the communicating member 24 'via the retaining member 104, the projecting member 90 can be fixedly attached to the faucet main body 23 and the pipe 37 'Lower cover 88b
And the upper part of the tube 37 'is covered with an upper cover 88a.

Therefore, (1) the water discharge pipe 95 can be configured to be rotatable 360 ° around the central axis X,
(2) A communication member 24 ′ around the axial direction (P direction),
The pipe body 37 ', the support member 38, the upper cover 88a, the lower cover 88b, the operation lever 59, and the water discharge pipe 95 are connected to the faucet main body 1.
It can be configured to rotate 360 ° with respect to a.

Further, when the upper cover 88a and the operation lever 59 are fixed, (3) the communication member 24 ', the tube 37', the support member 38, the lower cover 88b, and the like around the axial direction (P direction). The water discharge pipe 95 is connected to the faucet main body 1a by 360
° Can be configured to rotate freely.

Since the water discharge pipe 95 is configured to be rotatable around the central axis X by 360 °, the water discharge port space (water discharge allowable space) where the user can reach out is set wider than before. it can. For example, when the water discharge pipe 95 is rotated around the central axis X to the state shown in FIG. 2, the water discharge port space (water discharge allowable space) can be made wider than before, and the usability can be improved.

[0030]

As described above, the single-lever type faucet of the present invention is provided with a protruding member formed with a communication passage communicating with the drainage passage of the communication member in a state protruding from the faucet body. In addition, since a water discharge pipe longer than the water discharge pipe provided on the faucet main body is rotatably mounted on the projecting member, a water discharge port space (water discharge permissible space) to which a user can reach is conventionally provided. Can be set wider than that of, and the usability can be improved.
