TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a piping device that fully exerts the function of a terminal device attached to a piping point in a water distribution device distributed to more than one location.
[0002]
[Prior art]
Conventionally, a strainer as a garbage collection means is incorporated in each of the required faucets, and it is necessary to clean the garbage in each part.
[0003]
In addition, when a strainer mechanism is inserted upstream of the branching section to remove dust at one location, dust at locations where a strainer is not required is collected, which is inefficient.
[0004]
For strainer cleaning, methods using disassembly cleaning, backflow of water, and the like have been proposed, but all of these methods are troublesome.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to enable the cleaning of a strainer, which has been conventionally performed at each faucet, to be performed at once.
[0006]
Another object of the present invention is to eliminate the use of special means for the cleaning method in consideration of discharging dust generated at this time from terminal equipment that does not require a strainer.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the piping device of the present invention is characterized in that a branching device of a flow path having a garbage collection unit having a plurality of garbage collection units is provided with water passing through a part of the garbage collection unit. And a branch pipe through which water that normally passes through a plurality of garbage collection sections passes, and through which garbage collected in the garbage collection section flows by moving the garbage collection section. Things.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
When the header is provided with a branch having a built-in strainer, one of the branches forms a flow for passing water passing through the strainer, and the other forms a flow for removing dust accumulated in the strainer.
[0009]
At this time, the water that passed through the strainer is a terminal device that prevents the presence of dust, such as a thermostatic water / water mixing faucet, a single lever water / water mixing faucet using a disc valve, or a solenoid valve, or a terminal device used for drinking. Or a location that includes both.
[0010]
The debris-removed water is then directed to locations that include end devices that are resistant to small debris, such as single faucets, end devices that are not used for drinking, or both.
[0011]
【Example】
FIG. 1 shows an overall perspective view of a piping device 1 of the present invention. A branching tool 5 containing a strainer 4 as garbage collecting means is provided at a branching portion 3 of a water supply pipe 2 from a water pipe. The outlet of the branch pipe portion 7 forming the first flow path 6 branching downstream of the strainer 4 of the branching tool 5 is branched into a flow path 9 connected to the water supply header 8 and a flow path 11 connected to the water heater 10. 12 inlets. Water is supplied from the water supply header 8 to a basin faucet 13 as a terminal device via a water supply pipe 14, to a kitchen faucet 15 via a water supply pipe 16, and to a bathroom faucet 17 via a water supply pipe 18. Is done.
[0012]
Also, from the hot water supply header 19 connected to the hot water supply device 10, the hot water is supplied to the basin faucet 13 via the hot water supply pipe 20, the kitchen faucet 15 via the hot water supply pipe 21, and the bathroom faucet 17. Hot water is supplied through the pipe 22. The water or hot water flowing through the water supply pipes 14, 16, 18 and the hot water supply pipes 20, 21, 22 does not contain dust. Therefore, it is not necessary to provide a garbage collection means such as a strainer for the basin faucet 13, the kitchen faucet 15, and the bathroom faucet 17.
[0013]
On the other hand, the outlet of the branch pipe part 24 forming the second flow path 23 that does not pass through the strainer 4 of the branching tool 5 is connected to a garden faucet 25 provided outdoors. Garbage trapped by the strainer 4 is discharged from the garden faucet 25.
[0014]
FIG. 2 is a sectional view of the branching tool 5 and FIG. 3 is an exploded perspective view of the branching tool 5. In this branching tool 5, water entering from the inflow pipe 26 is divided into a branch pipe 7 that passes through the strainer 4 and a branch pipe 24 that does not pass through the strainer 4. At this time, the branch pipe part 7 is connected to the first flow path 6 for connecting the terminal equipment which is not troubled with dust, and the branch pipe part 24 is connected to the second flow path 23 for connecting the terminal equipment which is not so troubled even if there is dust. Connected.
[0015]
Although the dust 27 is captured by the strainer 4, the water flowing toward the branch pipe portion 24 causes the dust 27 attached to the strainer 4 to flow at the same time due to the force of the flow. Therefore, the dust is discharged from the garden faucet 25 connected to the second flow path 23.
[0016]
4 and 5 show another embodiment of the branching tool. FIG. 4 is a sectional view of the branching tool 45, and FIG. 5 is an exploded perspective view. The water that has entered from the inflow pipe portion 28 of the branching tool 45 passes through the branch pipe portion 32 through which only the water that has passed through the strainer 30 or the strainer 31 of the strainer member 29 passes, and usually the water that has passed through the strainer 30 and the strainer 31. When the member 29 is rotated, it is divided into a branch pipe portion 34 through which refuse 33 accumulated in the strainer 30 or the strainer 31 flows. Water that has entered from the inflow pipe portion 28 passes through the strainer member 29 and travels to the branch pipe portions 32 and 34.
[0017]
When it is felt that the water from the end device connected to the branch pipe portion 32 or the branch pipe portion 34 is poor, it is considered that dust is accumulated in the strainer 30. Thus, by turning the handle 35 of the strainer member 29 by 180 degrees, the dust 33 accumulated on the strainer 30 is discharged to the branch pipe portion 34. Then, the strainer 31 accumulates water debris entered from the inflow pipe portion 28. If the terminal device has been used for a long period of time and the water from the end device is still poor even after turning the handle 35 of the strainer member 180 by 180 degrees, remove the cap nut 36, remove the strainer member 29, and clean the strainer 30 and the strainer 31. can do.
[0018]
In addition, in this structure, it has a water stopping function by rotating by 90 degrees, and has a mechanism for notifying the operation state by a click feeling by the protrusion 37. The strainer member 29 is provided with a concave groove for maintaining watertightness, and provided with O-rings 38, 39, 40, and 41.
[0019]
FIG. 6 shows an example in which the connection of the pipes constituting the first flow path has a connection structure that does not generate dust. The connection structure of the branch pipe part 71 which only water which passed the strainer of the strainer member of the branching tool 70 passes, and the water supply pipe 72 which forms a 1st flow path is shown. The branch pipe portion 71 has a cylindrical portion 76 provided with a concave groove for fitting the flange portion 73 and the O-ring 74. An opening 77 is provided on an end surface of the water supply pipe 72 to be fitted with the cylindrical portion 76 of the branching tool 70, and a flange 78 is formed on an end surface of the opening 77.
[0020]
When the tubular portion 76 of the branching tool 70 is fitted into the opening 77 of the water supply pipe 72, the flange 73 and the flange 78 come into contact with each other. In this state, the coupling tool 80 provided with the slit 79 having substantially the same width as the total thickness of the flange portion 73 and the flange portion 78 is engaged over the flange portion 73 and the flange portion 78, so that the branching tool 70 and the water supply pipe are 72. Since an O-ring is used to keep the connection portion watertight, there is no need to use a seal tape or the like, and no dust is generated. If such a connection is adopted for all of the connecting portions of the pipes forming the first flow path, dust is not generated in the middle of the first flow path.
[0021]
FIG. 7 is an example of a terminal device for discharging garbage collected in a strainer, and shows a garden faucet 25.
[0022]
FIG. 8 shows another example of a terminal device for discharging garbage collected in a strainer. This is an example of using the end device for drinking. FIG. 8 shows a two-valve hot / water mixing faucet 46 that is strong against dust and has a spout tip 47 provided with a filter 48 that can be easily removed.
[0023]
If the water from the hot / water mixing faucet 46 becomes poor during use, washing the filter 48 is equivalent to cleaning the strainer of the entire house.
[0024]
9 to 10 show an example of a piping device in which a branching tool having a built-in strainer is incorporated in a header. FIG. 9 shows an overall perspective view of a piping device 50 of the present invention. A water supply header 52 connected to a water supply flow path 51 branched from a water supply pipe 2 from a water supply pipe is provided with a branching tool 5 containing a strainer 4 as garbage collection means. The outlet of the branch pipe part 7 forming the first flow path 6 branching downstream of the strainer 4 of the branching tool 5 is connected to a water supply header 52.
[0025]
Water is supplied from the water supply header 52 to a kitchen faucet 53 as a terminal device via a water supply pipe 54, and to a bathroom faucet 55 via a water supply pipe 56. The outlet of the branch pipe part 24 forming a second flow path that branches into a flow path that does not pass through the strainer 4 of the branching tool 5 is connected to a faucet 58 for a basin via a water supply pipe 57. Garbage trapped by the garbage collecting means is discharged from the basin faucet 58. Recently, due to the development of an automatic temperature setting function of a water heater, there are many cases in which a faucet, which is rather resistant to biting of dust, is attached, such as a two-valve hot / cold water faucet.
[0026]
In the hot water supply flow path 59 branched from the water supply pipe 2 from the water pipe, a hot water supply header 61 connected via a water heater 60 is also provided with a branching tool 5 having a built-in strainer 4 as garbage collecting means. Hot water is supplied from the hot water supply header 61 to the kitchen faucet 53 via the hot water supply pipe 62, and to the bathroom faucet 55 via the hot water supply pipe 63.
[0027]
The outlet of the branch pipe part 24 forming a second flow path that branches into a flow path that does not pass through the strainer 4 of the branching tool 5 is connected to a faucet 58 for a basin via a hot water supply pipe 64. Garbage trapped by the garbage collecting means is discharged from the basin faucet 57. The water or hot water flowing through the water supply pipes 54 and 56 and the hot water supply pipes 62 and 63 does not contain dust. Therefore, the kitchen faucet 53 and the bathroom faucet 55 do not need to be provided with garbage collecting means such as a strainer.
