Description

  The present invention is intended to solve the problems that occur in the siphon drainage system before the siphon starts.

  In the drainage system that has been used in the past, the horizontal drainage pipe is graded to give flow to the drainage, but as the length of the horizontal pipe increases, it is necessary to expand the space under the floor accordingly. there were. However, there is a drawback in that it is difficult to install a horizontal drainage pipe where there is a design restriction that the space under the floor cannot be expanded.

  In recent years, a drainage system using siphon force has been developed in order to solve the disadvantages of such a drainage system (Patent Document 1). This has attracted attention as a new drainage system without the need to add a gradient to the horizontal drainage pipe.

  However, it has been pointed out that the above siphon drainage system still has to be solved, and there is a time lag between the actual drainage of the watering device and the start of the siphon. As described above, when a large amount of drainage is performed at a time, there is a disadvantage that the drainage overflows from the drain on the washing station side before the siphon starts. Therefore, the design limit of the drainage system is determined by the start time of the siphon, in other words, the design of the horizontal pipe has a limit.

  The present invention solves such a drawback in the siphon drainage system, and provides a system in which drainage does not flow backward from the drain port even when the siphon start time is slightly late.

  The gist of the present invention is a siphon-type drainage system, in which a water storage means is laid between the plumbing device and the horizontal pipe, and when there is a large amount of drainage from the plumbing device at once, the drainage is temporarily performed. Further, the present invention relates to a siphon drainage system with a water storage function, characterized in that it is stored in the water storage means.

  The first aspect of the present invention is a siphon drainage system, which is a siphon drainage system provided with a chamber between a horizontal pipe and a trap.

  The second is a siphon drainage system with a chamber in the trap itself.

  The third is a siphon drainage system having a chamber between the watering device and the trap.

  The fourth is a siphon drainage system provided with a plurality of the chambers.

  The present invention provides a water storage function to the siphon drainage system, and even when the horizontal pipe is long or a large amount of drainage is made at one time, the drainage may flow backward before the siphon starts. The siphon drainage system has become a more complete system. Then, air is entrained in the drainage by the siphon force and a noise is generated, but there is also an effect that the time for the noise is shortened.

  The present invention solves the disadvantages of the siphon drainage system, and as described above, the joint portion between the watering device and the drain pipe, the trap, the drain pipe, etc. are provided with a water storage function, and the siphon start In the meantime, drainage is temporarily collected. For this reason, the design limit of the drainage system can be determined by the required wastewater treatment capacity without depending on the siphon start time as in the prior art.

  FIG. 1 shows an outline of a siphon drainage system. Reference numeral 31 is a standing pipe, 32 is a horizontal pipe, 33 is a bathtub as an example of a watering device, 34 is a washing place, and 35 is a trap. The horizontal pulling pipe 32 connected to the trap 35 joins the vertical pipe 31 with a drop H, and reference numeral 36 denotes a joining portion. In general, the horizontal pipe 32 is not made to join, but is merely placed over the surface of the floor slab 37, and does not take a gradient for drainage. Accordingly, the drainage force uses a siphon corresponding to the drop H, and when the siphon is activated, the drainage remaining in the horizontal pulling pipe 32 is forcibly drained by the siphon force.

  Speaking of the delay in the start of the siphon, it occurs when the horizontal pipe 32 is long, and is delayed even when the height of the watering device 33 is low. However, the disadvantages of having a large amount of wastewater tend to arise when these are combined. For this reason, in the present invention, when water storage means is laid between the watering device and the horizontal pipe, and there is a large amount of drainage from the watering device at once, the wastewater is temporarily stored in the water storage means. The horizontal pulling tube 22 is not affected until the siphon is started.

  Although it does not specifically limit as a water storage means of this invention, A pipe | tube part and a joint part are equipped with a water storage means, for example, a pipe body and container very thicker than the thickness of a piping part. Further, it is preferable to provide water storage means even in the trap, for example, to make the outer cylinder of the trap much larger than the conventional size. In the present invention, specific examples of these water storage means are referred to as chambers.

  In designing the drainage system, it is possible to further expand the design limit by increasing the diameter of the horizontal pulling pipe or a plurality of pipes.

  Hereinafter, it demonstrates in detail with the drainage system in a bathtub and a washing place. FIG. 2 is a partial view of a conventional drainage system, in which 1 is a bathtub, 2 is a drainage port, 3 is a washing place, and 4 is a drainage port. Reference numeral 5 denotes a trap, an inner cylinder 7 is disposed in the outer cylinder 6, the upper end of the inner cylinder 7 is connected to the drain port 4, and the lower end 7 a of the inner cylinder 7 is in a state of being lifted from the bottom surface 5 a of the trap 5. Yes. A drainage inlet 6 a is provided at the lower part of the outer cylinder 6 of the trap 5, and an inflow pipe 8 connecting to the drainage outlet 2 is connected to the drainage inlet 6 a. A drain outlet 6b is provided at an upper portion of the outer cylinder 6, and a horizontal pipe 9 having a large pipe diameter (usually 50A) is connected to the drain outlet 6b, and has a gradient of about 1/50. In such a drainage system, when a large amount of water is caused to flow from the bathtub 1, the water that fills the trap 5 loses its way to flow at a stretch, resulting in a reverse discharge from the drainage port 4 on the washing station 3 side.

  FIG. 3 is a partial view of the drainage system of the first embodiment of the present invention. In the drainage system of FIG. 2, a large capacity container (chamber) 10a is provided continuously to the drain outlet 6b of the trap 5. is there. Accordingly, the wastewater that has passed through the trap 5 does not flow into the horizontal pulling tube 9 at once, but is once stored in the chamber 10a. In other words, the wastewater is discharged by the amount of time lag that causes siphoning in the horizontal pulling tube 9. The water accumulated in the chamber 10a is also drained in the same manner when the siphon is started and retained in the chamber 10a.

  FIG. 4 is a partial view of a drainage system according to a second embodiment of the present invention, in which the outer cylinder 6 of the trap 5 has a large capacity, and this is a chamber 10b. Accordingly, the waste water flowing into the trap 5 is once stored in the chamber 10b, and when the siphon is started, the water stored in the chamber 10b is also drained in the same manner.

  FIG. 5 is a partial view of a conventional drainage system, which is an example of a sink trap with a large volume of drainage. In the figure, 11 is a sink and 12 is a drain outlet. The trap 13 is provided with an inner cylinder 15 which is continuous with an outer cylinder 14 and a bottom portion 14a. The intermediate cylinder 16 is disposed so as to cover the inner cylinder 15. The drainage from the sink 11 flows into the outer cylinder 14, dives at the lower end 16 a of the intermediate cylinder 16, then flows down into the inner cylinder 15 over the upper end 15 a of the inner cylinder 15 and flows into the horizontal draw pipe 17.

  FIG. 6 is a partial view of a sink drainage system according to a third embodiment of the present invention, which is an improvement of the drainage system shown in FIG. 5. The outer cylinder 14 of the trap 13 has a large capacity, and this is a chamber-10c. It is. Accordingly, the waste water flowing into the trap 13 is once stored in the chamber 10c, and when the siphon is started, the water stored in the chamber 10c is also drained in the same manner.

  FIG. 7 is a partial view of a drainage system for a washing machine according to a fourth embodiment of the present invention, in which the outer cylinder 24 of the trap 23 has a large capacity, and this is a chamber 10d. Accordingly, the waste water flowing into the trap 23 is once stored in the chamber 10d, and when the siphon is started, the water stored in the chamber 10d is also drained in the same manner. In the figure, 21 is a drainage hose from a washing machine (not shown), and 22 is a drainage port. The trap 23 includes an outer cylinder 24 having a drain port 24a for a horizontal pulling pipe, and an inner cylinder 25 provided therein, and a bottomed intermediate cylinder 26 is disposed on both the pipes. Yes. The drainage from the washing machine flows into the inner cylinder 25, dives at the lower end 25a of the inner cylinder 25, flows into the outer cylinder 24 over the upper end hole 26a of the intermediate cylinder 26, and then flows down into the horizontal draw pipe. is there.

  In this example, the outer diameter of the outer cylinder 24 is increased (the dotted line is a normal outer cylinder), and the function of the chamber 10d is provided here. In the example shown in the figure, the drainage port 24a is provided perpendicular to the outer cylinder 24, but it goes without saying that some of the outlets 24a are laterally oriented.

  The present invention is as described above, and is preferably used for a siphon drainage system. However, the present invention can be applied not only to such a drainage system but also to a drainage system in which a conventional horizontal pipe is sloped. In some cases, it can be used in conventional drainage systems as it is, and its range of use is wide.
