Description

  The present invention relates to an improvement of a siphon drainage system, and particularly relates to an improvement of a vent pipe in a siphon drainage system including a storage tank (hereinafter referred to as a chamber).

  In recent years, a siphon drainage system has been developed in place of the gradient drainage system conventionally employed (Patent Documents 1 and 2). FIG. 1 is a diagram showing a basic structure of a siphon drainage system applied to an apartment house. The drainage pipe 3 includes a drainage stack 1, a watering device 2, and a relatively thin drainage pipe 3 connecting both of them. Is basically a drainage system laid parallel to the slab S surface, and the outlet of the drainage pipe 3 is joined to the drainage stack 1 at a position lower than the slab S (water head difference Hs).

  The water in the drainage pipe 3 is pushed from the inlet side by the pressure of the water head difference Hp with the water circulating device 2 and moves in full flow, while the drainage pipe concerned by the suction force generated by the water head difference Hs on the outlet side. 3 is a system in which water in 3 is drained rapidly. The drainage pipe 3 gives a suction force to the water flowing in the drainage pipe 3 at a full flow by the water head difference Hp and Hs, so that a so-called siphon is generated.

  However, in the case of a watering device, for example, for a unit bath, a washing machine, a wash basin, or a kitchen, so-called sinking is performed, so that the chamber-4 is not provided to correspond to this. Must not. In the chamber 4, drainage is temporarily stored in the chamber 4 by drainage pipes 5 from the water-circulating devices 2 a, 2 b,. In the siphon drainage system provided with such a chamber-4 in the water circuit, water flows into the chamber-4, and the flow of supplying / exhausting the air in the chamber-4 generated when the chamber-4 is drained is used. The trachea 5 is required.

  Since water cannot enter the vent pipe 5 when water enters, the vent pipe 5 must not enter water. For this reason, an inlet / outlet of the vent pipe 5 is provided near the top of the chamber-4. Yes. The vent pipe 5 is provided in the chamber-4. However, the chamber-4 is required to be accommodated in a relatively narrow space, and a space for arranging the vent pipe 5 can be taken. There may be no.

  The present invention is intended to solve the conventional problems as described above. Part 1 is a technique for preventing water from entering the vent pipe even if the chamber is filled with drainage. The present invention provides a technique that makes it possible to arrange a vent pipe even in a narrow space.

  More specifically, the present invention provides a siphon drainage system having a chamber that is particularly adapted for a kitchen.

  The gist of the present invention is a siphon drainage system in which a watering device, a storage tank connected thereto, a drain pipe provided with suction from the storage tank, and a vent pipe connected to the storage tank are provided. The present invention relates to a siphon drainage system provided with a storage tank characterized in that the uppermost part of the trachea is higher than the bottom part of the watering device.

  Specifically, the watering device is a kitchen bowl, and it is preferable that a part of the vent pipe is located above the half of the kitchen bowl, and it is optimal that it is higher than the water surface when the kitchen bowl is full.

  In claim 1, the vent pipe is partly higher than the water level when the kitchen bowl is full. Drainage in the chamber does not enter the vent pipe, and the vent pipe connected to the top of the chamber is a chamber. In claim 2, which is guided through the inside to the outside, there is a feature that a special space for the chamber is not required, and the effect that the chamber can be installed in a relatively narrow place. There will be.

  The history of development of the siphon drainage system of the present invention is as follows. Up to now, the development of siphon drainage systems with chambers has been developed with a focus on sanitary. That is, the watering equipment connected to the chamber is a unit bath, a washing machine, and a wash basin, and the chamber capacity provided has a capacity that can store the maximum amount of water drained until the siphon is activated. The treatment capacity of the siphon drain pipe was designed to ensure a larger treatment flow rate than when the connected devices were simultaneously drained at the maximum flow rate, and the water level in the chamber would not rise after the siphon started.

  The maximum amount of drainage when the connected water supply equipment is drained is about 1.0 (L / sec) for the unit bath, about 0.7 (L / sec) for the washing machine, and about 0.5 (L) for the basin. Therefore, the total amount of drainage was 2.2 (L / second), so the chamber capacity was 50 from the amount flowing into the chamber before siphon activation. (L) If the siphon drainage pipe is 20A and the horizontal pulling length is up to about 5m, it can be processed at 0.75 (L / sec) per pipe, so three pipes and longer Was designed with the correspondence of piping with four.

  By designing in this way, no matter how much drainage is carried out, a design that does not overflow from the chamber before the siphon starts and that does not overflow from the chamber after the siphon starts is possible. It was.

  However, when there are few watering devices connected, for example, in the case of a kitchen or the like, the quality is clearly excessive. In addition to the high cost, in some cases the system such as a chamber is large. As a result, there was a drawback that it could not fit in a certain place.

  Here, if a kitchen is considered as a watering device, the appliance connected to the chamber is one kitchen (and a dishwasher is also connected in some cases). For this reason, there is no need to consider simultaneous use, such as for sanitary use, and there is little frequency of spillage like unit baths and washing machines. Is not something that lasts for a few minutes, only a short-term load (a few seconds to a minute). Judging from this point of view, designing the kitchen chamber with the same concept as the sanitary chamber was over-spec, and conversely, designing it to cope with excessive conditions In the case of normal continuous drainage, the siphon was not generated well, and there were also disadvantages such as clogging.

  For example, if the kitchen chamber is designed so as to clear both of the above concepts, the kitchen will be filled with water, and if it is drained, about 1.0 (L / sec) will be drained. To satisfy this design, the siphon drainage pipe has a treatment capacity that ensures a larger treatment flow rate than when the connected equipment is simultaneously drained at the maximum flow rate, and that the water level in the chamber does not rise after the siphon starts. 20A requires two siphon drain pipes. However, the continuous drainage that is usually performed is about 0.4 (L / sec), and basically only the continuous drainage is used, so the second is not used. However, even if it is rarely accumulated, only 0.3 (L / sec) flows, and siphoning is less likely to occur, causing clogging and dirt in the pipe.

  In addition, the practical use of the kitchen is equivalent to having no water in the kitchen bowl. However, it is often the case that a small jar is prepared and water is stored there to wash dishes. In other words, the only drainage that is used in the same way as a sink is when the water from the dredging is flushed. In other words, after a single siphon drainage pipe and continuous drainage treatment is performed smoothly. If the chamber capacity is set to the same size as the jar, water does not overflow from the chamber, so it can be said that there is no problem in practice.

  However, in the unlikely event that the kitchen is filled with water, if the chamber capacity is small, drainage will enter the vent pipe, which may hinder subsequent drainage. It is done. Therefore, even in such a method, it is necessary to devise so that water does not enter the ventilation pipe.

  Now, the chamber is equipped with a ventilation pipe for intake and exhaust of the internal air. However, it is not preferable that water enters the ventilation pipe, and it becomes impossible to ventilate due to the water entering, and noise is generated during drainage. , Or the occurrence of soot and off-flavors and increased ventilation resistance. For this reason, claim 1 of the present invention has a structure in which the waste water in the chamber does not enter the vent pipe, and the uppermost portion of the vent pipe is higher than the water level when the watering device is full. It is characterized by this. In the kitchen system, the problem was solved by making the height of the vent pipe higher than the water level when the kitchen bowl was full. The present invention can also be applied to the above-mentioned sanitary system.

  In addition, when the relationship between the kitchen bowl and the vent pipe is further described, it is sufficient that the uppermost portion of the vent pipe is above half of the kitchen bowl. That is, even if the vent pipe is not raised to the kitchen full water level, it is almost sufficient to raise it to about half of the kitchen bowl in consideration of the water level lowered by siphon drainage generated during that time.

  Further, according to claim 2 of the present invention, the existence of such a vent pipe is not so disturbed, the vent pipe is connected to the top of the chamber, and the vent pipe penetrates the inside of the chamber. It is structured to be led to the outside. That is, with this structure, the vent pipe does not exist outside the chamber, but the vent pipe exists inside the chamber, so that the fit into a narrow space is extremely good. It has something. The present invention is also applicable to the above-mentioned sanitary system.

  Hereinafter, the present invention will be further described with specific examples. FIG. 2 is a conceptual diagram of the present invention applied to a kitchen in an apartment house. It consists of a kitchen bowl 2A as a watering device and a siphon drain pipe 3A laid on the concrete slab S with no gradient. The chamber-4A is connected to this. That is, the trap 2B provided in the kitchen bowl 2A and the chamber 4A are connected by the drainage conduit 6A, and the drainage pipe 3A is connected to the bottom of the chamber-4A. The drain pipe 3A is a part where a siphon force acts, and is connected to a drain stand pipe (not shown) with a head difference Hs.

  Reference numeral 5A denotes a vent pipe which is connected to the top of the chamber 4A and extends upward as in the invention of claim 1, and its highest level 5A0 is above the water level when the kitchen bowl 2A is full. The vent pipe 5A is provided on the back side of the kitchen bowl 2A, and this does not disturb the height. With such a configuration, even if the inside of the kitchen bowl 2A becomes full, or even if the kitchen bowl 2A is drained at once, water does not enter the vent pipe 5A at all. In the figure, FL is a floor.

  The vent pipe 5A will be further described. The vent pipe 5A can be directly extended toward the drainage standpipe. For example, the vent pipe 5A vertically lowered from the highest position 5A0 as in the second aspect is the chamber-4A. It is also possible to have a structure that penetrates the inside 5A1 and extends as it is toward a drainage stand (not shown). According to this example, if there is a space in which the chamber 4A can be accommodated, the vent pipe 5A is also configured to be accommodated in a predetermined position, and it is sufficient to satisfy only the accommodation of the chamber 4A. System laying workability can be performed easily.

  The example shown in FIG. 2 is a configuration in which claims 1 and 2 are combined, and by simultaneously adopting the excellent points of both inventions, it is possible to easily cope with a watering device in which a reservoir is drained. It has become.

  The present invention is an excellent system as a countermeasure for watering equipment in which sinking is performed, and it goes without saying that the present invention can be applied to other similar watering equipment as well as a kitchen system.
