Description

  The present invention relates to an improvement of a joint portion of a siphon drainage system.

  The device drainage from the conventional watering device is laid with a slight gradient in the drain pipe, and a force that flows down to the drainage is given by this gradient, and this is led to the junction joint with the drainage standpipe. The formation of this gradient is a necessary requirement, and there is a problem that it takes time and cost for laying work for a long distance pipe, and the floor must also maintain an extra height.

  As a system for improving such a drawback, the present applicant has already proposed a technique in which instrument drainage is a siphon system (Patent Document 1). This siphon drainage system is the most excellent drainage system from watering equipment, and there is no part where drainage from one watering equipment joins other equipment drainage pipes before drainage in the drainage process. Moreover, since drainage uses siphon force, it is not necessary to set a special gradient in the drain pipe. Conversely, even if there is a slight upward gradient, drainage is sufficiently possible. Further, for this purpose, the tube material may be a relatively thin tube material of about 20 A. Furthermore, there is no restriction on the tube material, and a flexible tube such as a polybutene tube is optimal.

  Here, an outline of the siphon drainage system is shown in FIG. 1. A drainage pipe 1 that penetrates each floor, an appliance drainage pipe 3 that is led from a water-related appliance (tub) 2 on each floor, and an appliance drainage pipe 3 to the drainage standpipe 1. Is a drainage system composed of a junction joint 4 for connecting the drainage pipes 3 to the drainage pipe 1 as they are without joining the drainage pipes 3 on the way. The junction level to the junction joint 4 is a drainage floor. It is a system that lowers the level of the floor slab 5 and, if possible, lowers the joint (Hs: siphon head) for the first floor, thereby giving the siphon flow to the fluid in the appliance drainage pipe 3 and then joining the drainage pipe 1. is there.

  In particular, with regard to the flow of drainage from the water supply device 2, water is flowed to the non-gradient device drain pipe 3 using the potential energy of the drain head water head Hp, and then the device is operated using the potential energy of the siphon head water head Hs. In this system, the water in the drain pipe 3 is guided to the drain pipe 1. For this reason, even if the appliance drain pipe 3 has no gradient, even if there is a slight reverse gradient, siphon force can be applied to the water in the appliance drain pipe 3 by the potential energy of Hs.

  In the case of the siphon drainage system, although there is a cost, a pipe having a pipe diameter of about 20A is used because of the drainage flow rate.

  Well, in the drainage, there is a drainage drainage that drains after storing in a bathtub or the like, and a drainage that flows continuously from the faucet without storing water, but the siphon system tends to be mainly intended for the latter drainage. In addition, it is necessary to take into consideration the case where problems occur in the case of drainage with a large change in drainage flow rate.

  An object of the present invention is to provide a system having a sufficient drainage capacity by advancing the siphon start time for any of the above-described drainage and continuous drainage.

The gist of the present invention consists of a drainage vertical pipe penetrating each floor, an equipment drainage pipe guided from the water-related equipment on each floor, and a junction joint for connecting the equipment drainage pipe to the drainage vertical pipe. A drainage system that leads to drainage pipes without merging and lowers the level of merging at the junction joint from the level of the drainage floor slab, and is used as a trap for traps of watering equipment that is expected to have a large amount of drainage at a time. A plurality of instrument drain pipes including an upper instrument drain pipe disposed above the trap and a lower instrument drain pipe disposed below the upper instrument drain pipe. The pipe tip of the upper instrument drain pipe is disposed upstream of the pipe tip of the lower instrument drain pipe, and the drainage system is characterized in that the generation time of the siphon phenomenon in the instrument drain pipe is shifted.

  Since the present invention employs the above-described configuration, siphon drainage can be reliably performed, whether it is a drainage drainage drained after being stored in a bathtub or the like, or a continuous drainage continuously flowing from a faucet. In particular, a system that does not cause any problems even in the case of a drainage drainage in which the drainage flow rate varies greatly is obtained.

  In the drainage system using siphon force, the present invention can provide a drainage system that responds to changes in the drainage flow rate. When either the drainage drainage or the continuous drainage is mainly piped, the other drainage is provided. As it was pointed out that this would cause trouble, the present invention uses a plurality of drainage pipes in a watering device that is likely to be a particular problem, and the siphon function is generated with a time difference by specifying the positional relationship of the tips. As a result, a sufficient drainage function can be exhibited in any drainage state.

  And as a watering device which is mainly a problem, it is a bathtub from which a large amount of water is discharged at once, and is provided with a plurality of device drainage pipes for this drain trap, and a plurality of device drainage used. The pipe diameters of the pipes need not be particularly distinguished, and the pipe diameters are preferably the same.

  In order to shift the occurrence of siphon phenomenon in multiple appliance drain pipes, the tip of the drain pipe into which the drainage enters is misaligned up and down with respect to the drainage surface, and each drain pipe is full. It is a preferable method to shift the time of becoming.

  Here, the present invention will be specifically described with reference to FIG. Reference numerals 1 to 5 are the same as those defined in FIG. 1, and detailed description thereof will be omitted. However, a drainage pipe 1 that penetrates each floor and a drainage pipe 3 that is led from a water supply device 2 on each floor. And a junction joint 4 that connects the appliance drain pipe 3 to the drainage standpipe 1, and leads the drainage standpipe 1 without joining a plurality of instrument drainage pipes 3. The drainage system is lower than the level of the drainage floor slab 5, and a trap 7 of a watering device (tub) 2a, which is assumed to have a large amount of drainage at a time, is provided with a large-diameter short pipe (50A) 7a. Two instrument drain pipes 3a and 3b having the same pipe diameter (20A) are connected in the short pipe 7a, and the instrument drain pipes 3a and 3b are connected to the water surface of the drainage in the trap 7 (or short pipe 7a). The pipe tips 3a0 and 3b0 are arranged vertically and shifted back and forth, Instruments drainage pipe 3a, the difference provided the time of drainage of Mitsururyu enter into the 3b, whereby a drainage system by shifting the occurrence time of the siphon effect.

  Further, as described above, the action of applying siphon force to the instrument drain pipe is brought about by the potential energy of Hs, and the description thereof is omitted here.

  Now, in such a drainage system, only the lower pipe 3b is used for drainage at the time of continuous drainage with a low flow rate, while the lower pipe 3b is used for drainage with a large flow rate. Of course, the upper pipe 3a also becomes full, and this pipe 3a also causes a siphon phenomenon. In other words, if the drainage pipe 3 is a thick pipe, the beginning of the siphon's effect will be delayed, but if the drainage flow rate increases when the siphon is started earlier by using a thin pipe, both pipes become full and both pipes It becomes siphon drainage.

  FIG. 3 shows another example of the present invention, which is an example applied to the trap 7 of the sink 2b. Reference numerals 1 to 7 are the same as described above, and a description thereof will be omitted. Two instrument drain pipes 3a and 3b having the same pipe diameter (20A) are connected to the trap 7 of the sink 2b, and the pipe tips 3a0 of the instrument drain pipes 3a and 3b are located above the water surface of the drainage in the trap 7. The pipe tip 3b0 is arranged below. Accordingly, when the instrument drain pipe 3b side is first full flow, the drain pipe 3a is also full stream when the drainage water surface is higher than the pipe tip 3a0 of the instrument drain pipe 3a. In this way, a difference is made in the timing of the full flow of the drainage that enters the drainage pipe, thereby making it possible to shift the generation time of the siphon phenomenon.

  The drainage system using two drainage pipes can be applied to any watering device, and can be applied to both drainage and drainage in the case of continuous drainage. Moreover, it occurs early and its utility value is high.
