BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is a partially sectional side view of an embodiment of the present invention, and FIG.
1 is a plan view of FIG. 1, and illustration and description of parts common to those in the conventional example shown in FIG. 3 are omitted.

In the present embodiment, a part of a commonly used single lever-type hot / water mixer tap is disassembled while the mixer tap main body is installed, and a horizontal branch outlet and inlet are simply interposed and added thereto. This is convenient for a single lever type hot / water mixer tap which can communicate with a water purifier or the like.

The axial length of the cylinder 31 provided with the additional horizontal branch outlet and inlet is about 8.3 cm, which is shorter than the spout length of the hot / water mixer tap of 25 cm to 30 cm.
It is not so bulky.

The branch body 25 has a tap water inlet 2
6. The hot water inflow hole 27 and the mixed water outflow hole 28 are respectively penetrated in the axial direction like a lotus root. This tap water inlet 2
Numeral 6 communicates with the water pipe and with the tap water inlet of the fixed disk in the cartridge. Hot water inlet 27
Communicates with the water heater and the hot water inlet of the fixed disk in the cartridge. The mixed water outlet 28 communicates with the spout (6) and also with the mixed water outlet of the fixed disk in the cartridge.

Here, in the tap water flow hole 26,
A branch outlet 29 as a horizontal hole is communicated orthogonally, and a branch inlet 30 as a horizontal hole is orthogonally communicated with the mixed water outflow hole 28.

The columnar branch body 25 as described above is closely fitted to the cylinder 31 via a plurality of seals. An outer peripheral screw 32 is provided on the upper outer periphery of the cylinder 31.
And the outer peripheral screw 32 is screwed to the cap body 9 shown in FIG. Further, an inner peripheral screw 33 is provided on the lower inner periphery of the cylinder 31, and the inner peripheral screw 33 is screwed to the cylindrical rising portion (that is, the mixing plug main body) (5) shown in FIG.

The cylinder 31 has the branch outlet 2
An outlet hole 34 communicating with the branch inlet 9 is provided, and an inlet hole 35 communicating with the branch inlet 30 is provided. In addition, the close fitting surface between the cylinder 31 and the branch main body 25 forms the branch outlet 29.
A first annular groove 36 in the form of a band is recessed at each open end of the outlet or outlet hole 34, and a second annular groove 37 in the form of a band is recessed at each open end of the branch entrance 33 or the inlet hole 35. When the cylinder 31 and the branch body 25 are fitted, the fitting may be made in any direction.

This cylinder 31 is provided with a branch outlet hub 38 which fits tightly across the outlet hole 34 via a seal, and which fits tightly across the inlet hole 35 and has a branch outlet. A branch inlet hub 39 that slides in contact with the hub 38 is provided. These hubs 38 and 39 rotate the outer peripheral surface of the cylinder 31 by 360 °, but do not come off in the axial direction. That is, a slightly thick portion is formed at the lower portion of the cylinder 31, and the branch inlet hub 39 is mounted on the step portion 40, and the step portion is formed at the upper end of the cylinder 31 and the upper end of the branch outlet hub 38. 41 are formed and fitted stepwise.
Then, if the cap body (9) is screwed, these hubs 38 and 39 do not come off in the axial direction.

A branch outlet joint 42 is screwed to the branch outlet hub 38, and a third annular groove 43 in the form of a band is recessed at each open end of the branch outlet joint 42 and the outlet hole 34.

A branch inlet joint 44 is screwed to the branch inlet hub 39, and a strip-shaped fourth annular groove 45 is formed in each of the open ends of the branch inlet joint 44 and the branch inlet 33. Therefore, even when these hubs 38 and 39 rotate 360 °, they always communicate with the outlet hole 34 and the inlet hole 35.

The branch outlet joint 42 comprises a screw-in type spout 46 and a cap nut type receiving portion 47 rotatably fitted in the spout 46. The portion 46 is screwed to the branch outlet hub 38, and a switching valve 48 described later is screwed to the cap nut type receiving portion 47.

The branch inlet joint 44 is constituted by a threaded joint 49, in which a check valve 50 described later is provided.
Is provided.

The branch body 25 and the cylinder
31, the branch outlet joint 42, the branch inlet joint 44, and the like are assembled in a production factory, and the whole is sold as a part.

The switching valve 48 is, for example, an actual open flat 6-20.
As shown in Japanese Patent Application Publication No. 557, a pair of ceramic seal disks are provided with through holes, one seal disk is fixed, and the other seal disk is rotated by sliding contact. The foot of the handle 51 is locked. Therefore, by rotating the knob handle 51 by about 90 °, the through-holes are aligned or shifted to open and close the valve. Unlike a normal switching cock, not only does the O-ring not only drain well, but also opens and closes the valve. It can be very light.

The check valve 50 includes a poppet valve body 52,
A spring 54 for pressing the poppet valve body 52 against the valve sheet 53 and a bush 55 for receiving the valve sheet 53 and the spring 54 are provided. Therefore, the check valve 50 prevents hot water or water from flowing back through the mixed water outflow hole 28 into, for example, a water purifier.

Reference numeral 56 denotes a knock pin provided on the branch body 25, 57 denotes a knock pin hole, and 58 denotes a seal ring.

Next, the operation of this embodiment will be described. That is, a method of attaching the branch main body 25 having the horizontal branch outlet and the inlet of the present embodiment to a commonly used general single lever type hot / water mixer tap will be described. After removing the single lever (11) (see FIG. 3, the same applies hereinafter) from the single lever type hot and cold water mixing tap installed on the think tank and already used, the cap body (9) is removed,
Next, the cartridge (8) is taken out and fitted to the cylindrical rising portion (mixing tap main body) (5) on which the cartridge (8) has been mounted so far, to the cylinder-31 of this embodiment. The placed branch body 25 is placed and positioned by the knock pin 56.

Next, the cylinder 31 is turned using a large spanner or the like, and the inner peripheral screw 33 of the cylinder 31 is screwed to the cylindrical rising portion (5). Next, after the detached cartridge (8) is placed and positioned by the knock pin, the cap body (9) and the single lever (11) are attached.

Therefore, a switching valve 48 is connected to the branch / outlet joint 42 attached to the cylinder 31. The switching valve 48 is connected to, for example, a raw water hose of a water purifier, and to the branch / inlet joint 44. Connect the hose for water purification of the water purifier. Therefore, such an assembling operation can be easily performed by a layman.

After the above assembling work, if the purified water is to be generated, the switching valve 48 is opened and the single lever 11 is operated for discharging water, so that the purified water is discharged from the spout (6).

The branch body 25 of this embodiment can be applied not only to the installed single-lever-type hot / water mixer tap, but also to the production of a new single-lever-type hot / water mixer tap. In short, the mixer tap body with spout, the cartridge, the cap body and the like can be used to directly connect a water purifier or a treated water generator such as alkaline ionized water.

[0035]

According to the present invention, a cylinder having a horizontal branch outlet and an inlet and a closely fitted branch main body are detachably provided on a commonly used single lever type hot / water mixer tap. If the branch outlet and the inlet are directly connected to a water purifier or the like, the spout of the hot and cold water mixing tap can be used as it is.

In particular, since the hubs at the branch outlet and the inlet are stacked one on another and can be rotated by 360 ° around the outer periphery of the cylinder, the installation position of the water purifier and the like is given a degree of freedom, and the spout is swung. Does not interfere with Further, even if a cylinder having a horizontal branch outlet and an inlet and a branch main body are added to a hot / water mixer tap having a long spout, the installation space is not occupied.
