Abstract

PURPOSE:To easily selection-switch original water surely to the water flow passages in three directions by turning a rotor. CONSTITUTION:A drain port 23 for original water of a successive rotor 21 is allowed to communicate to a drain passage 9 for original water and a drain port 24 for shower is allowed to communicate to a drain passage 10 for shower, closing a branched water passage 15 by a valve body 26 by meshing an operating hook 28 by turning a rotor 21. Further, the meshing of the operating hook 28 is released to operate a valve body 26, and the branched water passage 15 can be opened, and the original water which flows into a valve chamber 3 through an original water passage 8 can be easily selected surely in three directions, i.e., towards a drain passage 9 for original water, drain passage 10 for shower, and the branched water passage 15.

It's a snat.

Reference numeral 21 denotes a cylindrical rotor having a bottom, which is rotatably provided in the valve chamber 3, and 22 has a required width on the outer peripheral surface of the rotor 21 so as to correspond to the raw water passage 8. Raw water introducing passages formed by cutting in concentric circles, and 23 and 24 are rotors 21 to correspond to raw water and shower drainage passages 9 and 10, respectively.
Is a drainage port for raw water / shower formed on the outer peripheral wall of the work piece.
The rotors 21 are formed in a staggered shape with a required interval so that the rotors 21 can be sequentially rotated under the state of the cams of 8 and 29 to communicate with the corresponding drainage channels 9 and 10 for raw water and shower. Reference numeral 25 is a mounting member for a valve body with a substantially square columnar detent that is installed inside along the center line of the rotor-21, and 26 is a mounting member 25 for corresponding to the branch water channel 15.

Are a pair of valve actuating pawls on both sides which are concentrically formed at a front end of the valve disc 26 at a predetermined interval, and each actuating pawl 28 has a substantially block-like shape with one side having an inclined surface.

Reference numeral 29 denotes an operating claw which is provided so as to correspond to the operating claw 28 so as to project at the edge of the branch water passage 15.
It is supposed that the valve body 26 is operated back and forth by closing and removing it to close and open the branch water channel 15. In addition, under such a state that the operating claws 28 and 29 are out of alignment, the outer peripheral surface of the rotor-21 is for raw water.
The shower drainage channels 9 and 10 are closed, and the operating claw 28
.When 29 is in a state of crushing, rotor-21
The raw water and shower drains 23 and 24 are rotor-21
Drainage channel 9 for raw water and shower that responds appropriately by rotating
・ It is supposed to communicate with 10. Reference numeral 30 is a pressing plate of the rotor-21, and 31 is a lever attached to a rotation shaft 32 of the rotor-21. In addition, 33 shows a water purifier.

Next, the operation of the running water switching device constructed as described above will be described. First, the mouth 2 of the stopper 1 is connected to the tap, the branch pipe 16 is connected to the water inlet of the water purifier 33 with a hose or the like, and the outlet of the water purifier 33 is similarly returned to the return water channel 18 Connect to. Then, rotate the lever 31 to position it at A in FIG.
It is rotated together with 21, and the operating claws 28 and 29 are aligned. Then, the raw water drainage port 23 of the rotor 21 communicates with the raw water drainage channel 9, and the raw water flowing into the valve chamber 3 through the raw water channel 8 and the raw water introduction channel 22 passes through the raw water drainage channel 9. Drain outward (see Fig. 6). At this time, since the shower drain 24 of the rotor 21 is formed in an alternating manner with the raw water drain 23, it does not communicate with the shower drain 10, and the branch channel 15 is a spring. The material is closed by the valve body 26 urged by the material 27.

Further, the rotor-2 is arranged so that the lever 31 is positioned at B in FIG.
When it is rotated in the counterclockwise direction together with 1, the branch water channel 1
5 is closed by the valve body 26, the shower drain 24 of the rotor 21 communicates with the shower drain 10, and the raw water enters the shower chamber 4 through the shower drain 10.
The shower cap 13 is dispersed while hitting the dispersion plate 12.
Drain more in a wrinkle shape (see FIG. 7). In addition, at this time, the raw water drainage port 23 is blocked by the outer peripheral surface of the rotor 21 and no inflow of raw water occurs.

Further, when the lever 31 is rotated in the counterclockwise direction together with the rotor 21 to position the lever 31 at C in FIG. 5, the engagement of the operating pawls 28 and 29 is released, and the valve body 26 is made of a spring material. Moved in the direction of rotor-21 against the bias of 27,
The branch water channel 15 is opened. Then, the raw water flowing into the valve chamber 3 is caused to flow out to the branch water channel 15. At this time, since the raw water / shower drainage channels 9 and 10 are closed on the outer peripheral surface of the rotor 21 respectively, no inflow of raw water occurs. The raw water that has flowed into the water purifier 33 from the branch water channel 15 through the branch pipe 16 is purified and then drained from the raw water drainage channel 9 through the return water channel 18 (see FIGS. 8 and 9).

Further, when the rotor 21 is rotated counterclockwise together with the lever 31, although the operating pawls 28 and 29 are brought into a state of being intermeshed again, the outer peripheral surface of the rotor 21 is kept in the raw water channel. Block 8 to stop the supply of raw water. Similarly, the lever 21 may be rotated by the lever 31 to engage the operating pawls 28 and 29, and the raw water may be selectively switched while being removed.

The running water switch according to the present invention can be applied not only to the water purifier 33 but also to a water heater or various running water equipment pipes.

[0016]

Since the present invention is constructed as described above, the branch water channel 15 is blocked by the valve body 26 by rotating the rotor 21 and engaging the operating pawls 28 and 29 with each other. , The raw water drainage port 23 of the rotor 21 is communicated with the raw water drainage channel 9 and the shower drainage port 24 is communicated with the shower drainage channel 10, respectively, and the operating claws 28, 29 are removed from the knives. The branch water channel 15 can be opened by operating the valve body 26 with the raw water flowing into the valve chamber 3 through the raw water channel 8 for the raw water drainage channel 9 and the shower drain channel 10. The branch water channel 15 can be appropriately and selectively switched to three directions reliably and easily. Further, according to the present invention, when the branch water passage 15 and the return water passage 18 are connected to the water purifier 33 or the like, the purified water or the like can be drained directly from the raw water drainage passage 9 of the plug 1. .
