Description

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

  The siphon drainage system is proposed with respect to the conventional gradient drainage system (patent document 1). Such a siphon drainage system is characterized in that the horizontal pipe can be laid on the floor slab without any gradient, and is excellent in terms of workability and comfort. However, it is also true that there is a time lag between drainage and the generation of siphon force. If there is a large amount of drainage at a time, such as a unit bath (UB), storage of chambers, gradient drainage pipes, etc. It was necessary to temporarily store the wastewater with a portion (hereinafter described with a chamber). A siphon drainage system having such a chamber is usually provided with a chamber between a trap and a horizontal pipe provided in a watering device, and a horizontal pipe is attached to the bottom of the chamber or a position close thereto. It is what is done.

JP 2000-299447 A

  In a siphon drainage system having a chamber, the water level in the chamber rises immediately after drainage from the watering device into the chamber until the siphon starts to work. When the siphon force is exerted, the flow rate that can be processed in the siphon is superior to the amount of drainage flowing into the chamber, and the water level is lowered. At that time, when the water level in the chamber is lowered to the position where the horizontal pipe is connected, the water is drained while sucking in air. For this reason, noise called zoom was generated. And since this sound sucks air and siphon force decreases, the amount of water flowing into the chamber from the watering device and the amount drained just keep the equilibrium state, and for a long time. Continue to ring. Furthermore, when the drainage was finished, a humming noise was generated when the siphon was cut.

  In order to prevent these drainage noises, it could be suppressed by installing a siphon breaker, etc., but this always controls (decreases) the siphon force, and the water level in the chamber has risen. However, the siphon power was weakened and the wastewater treatment could not catch up and the water overflowed.

  The present invention has been made in view of the prior art as described above. When the water level in the chamber is high, the siphon force is fully exerted at full flow to treat a large amount of water, The present invention provides a siphon drainage system having a chamber in which siphon force is cut off when the water level becomes low or siphon force is weakened.

  The gist of the present invention is a siphon drainage system in which a chamber is connected between a watering device and a horizontal pipe, wherein a bypass pipe is installed in the chamber and the horizontal pipe, and an opening in the chamber of the bypass pipe is provided. The siphon drainage system is characterized in that the position is provided at a position higher than the connection position of the horizontal pipe.

  The present invention is as described above, and when the water level in the chamber is high, the inside of the horizontal pulling pipe becomes a full flow and fully siphon force is processed to process a large amount of water, and when the water level in the chamber becomes low, the bypass pipe A siphon drainage system having a chamber in which more air is involved and the siphon force is weakened can be provided.

  In a siphon drainage system having an existing chamber, for example, since a horizontal pipe is only connected to the bottom of the chamber, the drainage overflows when the amount of inflow into the chamber is large. was there. And even if the siphon force works, the equilibrium state while sucking in air continues for a long time, and as described above, the zoom sound that sucks in air is generated.

  This drainage system is made to eliminate such drawbacks, and the entire system is as follows. First, immediately after the start of drainage from the watering device, since there is a time lag until the siphon start, water accumulates in the chamber and the water level rises. The water level in this chamber rises from the opening of the bypass pipe. Therefore, it will be in the state which cannot suck in air from an opening part.

  Next, when siphoning by the horizontal pulling pipe is started, the bypass pipe is in a state where it cannot suck air. And water is also sucked in from the bypass pipe, and depending on the height of the bypass pipe, the bypass pipe side is also drained. For this reason, the horizontal pulling tube exhibits the siphon force fully, and the water in the chamber is drained by the siphon force. When the siphon force is fully applied to the horizontal pulling tube, the amount of wastewater treatment becomes larger than the amount of inflow into the chamber, and the water level in the chamber decreases.

  In the second half of the siphon drainage, the water level in the chamber is lowered and the opening of the bypass pipe comes out of the water surface. For this reason, the bypass pipe sucks only air, and the horizontal pulling pipe sucks only water from inside the chamber. Therefore, the horizontal pulling tube does not absorb water and air simultaneously from the inside of the chamber, and noise such as zooming noise is not generated. Then, the siphon force is weakened, and the amount of wastewater treated and the amount of inflow into the chamber are equalized, resulting in an equilibrium state.

  At the final stage of drainage, the proportion of air entering from the bypass pipe increases, and the siphon is cut when the drainage is completed. For this reason, there is no noise at the time of drainage completion.

  As described above, in the chamber-drainage system of the present invention, the bypass pipe is arranged from the chamber in addition to the horizontal pulling pipe, and the water level in the chamber is adjusted. The amount of inflow into the chamber and the amount of drainage from the horizontal pipe are adjusted, and the amount of drainage is adjusted according to the water level in the chamber to reduce noise during drainage.

  It is preferable that the horizontal pipe is connected to the bottom surface of the chamber or a portion close to the bottom surface of the side surface (Claims 2 and 3) from the top of the drainage system, while the bypass pipe has an opening at the horizontal pipe in the chamber. It is provided at a position higher than the connecting portion of the pipe, and is connected to the side surface of the chamber or over the side surface (claims 4 and 5). More specifically, the bypass pipe extends to a position higher than the horizontal pulling pipe, then has a bent portion, and further reaches the bypass opening in the storage portion from the bent portion downward (Claim 4). Specifically, it has an inverted groove shape, an inverted U shape, an inverted V shape, and the like.

  In some cases, a plurality of horizontal pipes are connected to the chamber. In this case, it is sufficient that a bypass pipe is installed in at least one of these horizontal pipes.

  In addition, although the storage part of the present invention is described as a representative chamber, it is a matter of course that a chamber for storing a large amount of drainage is used. Is mentioned. The shape of the storage portion is not particularly limited, and it is needless to say that the storage portion may be a vertically long shape or a horizontally wide shape. Furthermore, the number of storage units is not limited to one, and it goes without saying that the storage unit may be divided into a plurality of storage units or may be a plurality of independent storage units.

  That is, the chamber may be divided into a plurality of parts and may be provided with a communication portion that connects the chambers. In this case, a horizontal drawing pipe and a bypass pipe are installed in each of the divided chambers. Item 7), the opening position in the chamber of the bypass pipe is provided at a position lower than the communicating portion (Claim 8).

  Such a chamber partitioning method is arbitrary, and can basically be exemplified by partitioning the inside of one chamber with a partition wall having a lower height than the peripheral wall of the chamber. In this case, the upper end of the partition wall is used as a communication portion. It is also possible to completely partition the interior of the chamber with a partition wall and form a communication hole in the partition wall. Furthermore, it is also possible to form two chambers and to provide a communication pipe that connects them. In addition, when the chamber is divided into a plurality of compartments, drainage pipes from the watering device can be introduced into each chamber.

  In the above example in which a plurality of chambers are formed, the case where drainage flows into one chamber from a watering device will be described. In normal drainage, siphon generation occurs in the chamber on the side where drainage flows. Occurs and air enters from the bypass provided in another chamber. However, if there is a large amount of drainage at once, the drainage flows into the other chamber from the communication part (communication hole, communication pipe). Thus, a large amount of waste water is stored, and siphon force is generated from any chamber.

  Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a side view (A) and a plan view (B) showing a first embodiment of the present invention. In the figure, 1 is a chamber (reservoir), and 2 is a drain pipe from a watering device (not shown). Reference numeral 3 denotes, for example, a 20φ horizontal pulling tube. The chamber-1 has a peripheral edge 1a and a bottom 1b, and is normally closed by a lid, but this lid is not shown. The horizontal pipe 3 is connected to the bottom 1b of the chamber-1 and is laid on the floor slab 4 without any gradient. The tip of the horizontal pipe 3 is a pipe that joins a drainage stand (not shown) with a head difference and produces a siphon force.

  In the illustrated example, the bypass pipe 10 is connected through the side surface of the chamber 1, and the opening 11 is 10 d (of the opening of the bypass pipe) than the connection (opening) 3 a of the horizontal pulling pipe 3. It is at a higher position by (height). The rear end of the bypass pipe 10 is an example connected to the horizontal pull pipe 3 outside the chamber-1.

  Therefore, when the waste water from the instrument flows into the chamber-1, it flows into the horizontal pulling pipe 3, but water accumulates in the chamber-1 while the siphon is not activated. When the water level reaches 10d, the opening 11 of the bypass pipe 10 is also blocked. In this state, when a siphon force is applied, water is drained by the siphon force through the horizontal pulling pipe 3 and the bypass pipe 10. However, when the water level in the chamber-1 drops to 10d, air is sucked from the bypass pipe 10, but the siphon is activated in the horizontal draw pipe 3 as it is. However, since air enters from the bypass pipe 10, the siphon force decreases accordingly. Then, drainage is continued while the siphon force is reduced, and air is hardly drawn from the horizontal pulling pipe 3 even when the siphon is cut off.

  For this reason, while the siphon is being activated, water is not sucked from the horizontal pulling tube 3, and there is no noise of noise, and the noise of gurgling due to entrainment of air at the end of the siphon is also reduced. Become.

  In the drawing, one drain pipe 2 from the watering device is shown. However, the present invention is not limited to this, and the drain pipes from a plurality of watering devices are connected to the chamber-1. It goes without saying that it can be done.

  FIG. 2 is a side view (A) and a plan view (B) showing a second embodiment of the present invention. The bypass pipe 10 extends toward a position higher than the horizontal draw pipe 3, and then has a bent portion, and further extends downward from the bent portion to reach the bypass opening 11, and overcomes the side surface of the chamber-1 to form a reverse groove. This is an example. The diameter 10a of the bypass pipe 10 is usually 20A, 16A, or 13A, and generally the noise becomes smaller as the diameter becomes smaller. Further, the height (bypass pipe height) 10c of the bypass pipe 10 from the horizontal pulling pipe 3 is arbitrary, but in general, when the height is 20 cm or more, water cannot be sucked from the bypass pipe. It can be a dual-purpose tube. Next, the interval 10b between the joint portion of the bypass pipe 10 and the horizontal draw pipe 3 and the chamber-1 is arbitrary, but the interval 10b is preferably as short as possible from the viewpoint of workability, workability during inspection, and the like. Is desirable. Further, the height 10d of the opening 11 of the bypass pipe 10 is preferably about 2 to 5 cm. Generally speaking, the smaller the 10d is, the shorter the noise generation time is. Each of these conditions is selected mainly in consideration of the amount of drainage discharged at a time.

  FIG. 3 is a side view showing a modification of the second embodiment of the present invention. In this example, the bent portion (horizontal portion in FIG. 3) of the bypass pipe 10 penetrates the side surface of the chamber-1 to form a reverse groove shape, and the bypass opening portion faces downward. This is an example in which the configuration of the tube 10 is compactly gathered.

  FIG. 4 is a perspective view showing a third embodiment of the present invention. That is, this is an example in which two horizontal pulling pipes 3 are connected to the chamber 1, and a bypass pipe 10 is connected to each horizontal pulling pipe 3. However, in some cases, it is only necessary to provide the bypass pipe 10 in one of them.

  FIG. 5 is a perspective view (A) and a side view (B) showing a fourth embodiment of the present invention. That is, the inside of the chamber-1 is divided into two chambers 1A and 1B by a partition wall 1c having a lower height than the peripheral edge 1a. For this reason, the chambers 1A and 1B have a top portion of the partition wall 1c having a lower height. It is the structure used as the communication part 1d. The horizontal pulling pipe 3 is an example in which the chambers 1A and 1B are separately provided, and the bypass pipes 10 are also installed respectively. The height 10d of the opening 11 of the bypass pipe 10 is preferably lower than the communication portion 1d, that is, the top of the partition member 1c.

  In the illustrated example, the drainage pipe 2 from the watering device is connected to the chamber 1A, but the drainage pipe 2 may be connected to the chamber 1B side, and moreover, from a plurality of watering devices. It goes without saying that a drain pipe (indicated by the alternate long and short dash line) can be connected to the chamber 1A or 1B. What is necessary is just to form the magnitude | size of the capacity | capacitance of chamber 1A and 1B arbitrarily, for example, if it comprised so that the capacity | capacitance by the side of the chamber 1A mainly used for siphon drainage may be made small, the time until it becomes full with drainage will be short. Thus, the siphon phenomenon can be generated in a shorter time.

  Now, the flow of drainage will be described. The drainage introduced from the drainage pipe 2 flows into the chamber 1A. And when it flows in the horizontal pulling pipe 3 connected to the chamber 1A and is filled with drainage, a siphon phenomenon occurs and drains continuously. The bypass pipe 10 also performs the same function as described in FIG. On the other hand, when draining drainage from a water supply device such as UB, the processing capacity is insufficient in the chamber 1A alone, so that the drainage passes over the communication portion 1d at the top of the partition wall 1c and accumulates in the chamber 1B. . Therefore, the same drainage effect as that of the chamber 1A is brought about on the chamber 1B side.

  FIG. 6 is a perspective view showing a fifth embodiment of the present invention. That is, in this example, the interior of the chamber-1 is completely partitioned by the partition wall 1c, and a communication hole 1e is formed in the vicinity of the lid portion (not shown) of the partition wall 1c so that the waste water flows between the two chambers. It is something to be made. Of course, the height 10d of the opening 11 of the bypass pipe 10 is preferably lower than the communication hole 1e.

  FIG. 7 is a perspective view showing a sixth embodiment of the present invention. That is, in this example, two chambers 1 and 1 are provided side by side, and are communicated by a communication pipe 1f in the vicinity of a lid (not shown) of each chamber. In this example, the height 10d of the opening 11 of the bypass pipe 10 is set lower than that of the communication pipe 1f. This example is particularly effective as a measure for avoiding obstacles by dividing the chamber side when there is an obstacle such as a pillar at the position where the chamber is installed.

  The present invention is as described above, and can be widely applied to drainage drainage from all watering devices such as a washing machine, a wash basin, and a kitchen including UB, and the range of use is extremely wide.
