Description

  The present invention relates to an improvement of a siphon drainage system, and more particularly, to provide a siphon drainage system that accelerates siphon activation.

  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 siphon drainage pipe can be laid with no gradient with respect to the slab surface, and is excellent in terms of workability and comfortability. However, it is also true that there is a time lag between drainage and the generation of siphon force. When there is a large amount of drainage at a time, such as a unit bath (UB), the reservoir is provided and the drainage is temporarily stored. (Patent Document 2). A siphon drainage system provided with such a storage part is usually provided with a storage part between a watering device and a siphon drainage pipe, and a siphon drainage pipe is attached to this storage part.

  Now, in a siphon drainage system equipped with a reservoir, immediately after drainage from the watering device into the reservoir, the water level in the reservoir rises until the siphon starts to work, When the pressure is exerted, the flow rate that can be processed in the siphon is better than the amount of drainage flowing into the reservoir, and the water level is lowered.

  As a problem of the siphon drainage system provided with such a storage part, the size of the storage part is the biggest problem. That is, an excessively large storage portion cannot be stored under the floor, and reduction as much as possible is desired. As a problem with respect to the reduction of the storage part, it is the biggest problem to speed up the siphon activation.

The gist of the present invention is a siphon drainage system having a reservoir between a watering device and a siphon drain pipe, wherein the reservoir is partitioned into a plurality of unit reservoirs, and each unit reservoir is defined as a predetermined unit. comprising a communication portion for connecting with a height, which according to the siphon drainage system, characterized in that the siphon drain pipe is connected to the side surface of the bottom or near the bottom of each such unit reservoir, communicating portions of each unit reservoir This is a siphon drainage system whose height is equal to or higher than the siphon activation Hp.

  The present invention is as described above. According to the first aspect of the present invention, the siphon activation is generated at an early stage, and the storage portion is designed to be as small as possible. In this case, a siphon drainage system can be provided that can cope with it. The effect of claim 2 and below will be described in the next section.

  The main purpose of providing the storage unit in the drainage system is to temporarily store the drainage for the time lag until the siphon is generated. However, the capacity of the storage unit can be reduced by generating the siphon earlier. However, the storage section is generally installed between the slab and the floor.Therefore, not only the width and depth of the storage section, but also the height of the storage section should be as low as possible. Attempts have been made to activate the siphon at an early stage by partitioning and partitioning the storage part into small parts.

  However, when the siphon is generated, the water in the siphon drain pipe moves so as to be pushed at full flow from the front end (watering device side), and then the rear end of the siphon drain pipe is suspended, and this suspended section The water in the siphon drainage pipe is drastically drawn out when the drainage of the water drops. However, there is a certain condition for the generation of this siphon, and it is a matter of course that the pulling force (siphoning force) of the drooping portion on the rear end side is necessary. It was also found that the force to press was also necessary.

  The force that pushes water from the front end side of the siphon drain pipe is the water head applied to the front end side, and the water head that causes a certain force or more to start the siphon with the water head is called siphon activation Hp. It has been found that Hp is the largest factor that generates siphon force. The siphon activation Hp is determined by the inner diameter and length of the siphon drain pipe, the length (Hs) of the drooping portion, etc., but in reality, the water level in the reservoir is not higher than the siphon activation Hp. And siphons will not occur. In other words, it has been found that no matter how much water accumulates in the reservoir, no siphon is generated when the water level is below the siphon activation Hp, and a sufficient function as the reservoir cannot be performed.

The present invention has been made based on the above knowledge, and it is possible to divide the storage part into a plurality of parts (referred to as unit storage parts) and to generate siphons at an early stage as compared with the case where the storage part is not divided. That is, the greatest feature of the present invention is that the storage section is divided into a plurality of unit storage sections and siphon drainage is performed, and the height to the communication section connecting the unit storage sections is higher than the siphon activation Hp. By setting and raising the water level quickly for each unit reservoir, the water in the pipe is surely pushed from the front end side of the siphon drain pipe . This, combined with the pulling force of the drooping water, led to an early and reliable observation of siphon activation.

Such a partitioning method of the storage part is arbitrary, and basically the inside of one storage part can be exemplified by partitioning in a horizontal direction with a partition part (partition wall) whose height is lower than the peripheral wall of the storage part ( Claim 2 ). In this case, the upper end of the partition wall is used as a communicating portion (Claim 4 ). It is also possible to form a connecting portion that completely partitions the inside of the storage portion with a partition wall and forms a communication hole in the partition wall. Furthermore, it can also be set as the connection part provided with the communicating pipe which comprises two storage parts and connects these. In addition, when the storage part is divided into a plurality of sections, it is common to introduce the drain pipes from the watering devices to the partitioned storage sections. The standing position, the standing angle, etc. of the partition part (partition wall) partitioning the storage part are arbitrary, for example, it is configured obliquely so as to reduce the capacity mainly used for siphon drainage (Claim 3 ). By doing so, the time until the water is filled with drainage is shortened, and the siphon phenomenon can be generated in a shorter time.

  In the example in which the storage unit is divided into two unit storage units, and the case where drainage flows into one unit storage unit from a watering device, the unit storage unit on the side into which the drainage flows during normal drainage If siphoning occurs at an early stage and there is a large amount of drainage at once, the drainage will temporarily flow into the other unit storage part from the communication part (communication hole, communication pipe) to store a large amount of wastewater. And siphon force is brought from any unit storage part.

  One or a plurality of siphon drainage pipes are connected to a portion near the bottom surface of the unit storage portion or the side surface of the side surface where the storage portion is partitioned. The siphon drainage pipe may have a relatively thin pipe diameter unlike a conventional gradient drainage pipe, and a flexible polybutene pipe or a cross-linked polyethylene pipe is used. However, it can also be arranged on the lower surface of the slab.

  Now, in a siphon drainage system equipped with a reservoir, immediately after drainage from the watering device into the reservoir, the water level in the reservoir rises until the siphon starts to work, When the pressure is exerted, the flow rate that can be processed in the siphon is better than the amount of drainage flowing into the reservoir, and the water level is lowered. At that time, when the water level in the storage part is lowered to the place where the siphon drain 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 is reduced, the amount of water flowing into the reservoir from the watering device and the amount of drained water just keep the equilibrium state and it will sound for a long time. to continue. In addition, when the drainage is finished, there is a case where a gurgling sound is generated when the siphon is cut off.

  In order to prevent these drainage noises, it could be suppressed by installing a vent valve, etc., but this always controls (decreases) the siphon force, and the siphon force is maintained even when the water level in the reservoir rises. There is a problem that water is overflowing because the wastewater treatment cannot keep up.

Therefore, in order to cope with this problem, as a secondary configuration of the present invention, a bypass pipe is installed in the storage section, and the opening position in the storage section of the bypass pipe is provided at a position higher than the connection position of the siphon drain pipe. (Claim 5 ) It corresponds.

  That is, the water level in the reservoir, that is, the height to the communication part of each unit reservoir is made higher than the siphon activation Hp, and siphon force is exerted at an early stage to treat a large amount of water, and the water level in the reservoir is low. Then, the siphon drainage system provided with the storage part that air is drawn in from the bypass pipe and the siphon force is weakened can be provided.

  More specifically, in relation to the bypass pipe, immediately after the start of drainage from the watering device, there is a time lag until the siphon start, so that water accumulates in the reservoir and the water level rises. The water level in the reservoir 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 siphon drain pipe is started, the bypass pipe is in a state where it cannot suck air. Accordingly, water is also sucked in from the bypass pipe, and the bypass pipe side is also used for drainage treatment, although it varies depending on the height of the bypass pipe. For this reason, the siphon drain pipe fully exhibits the siphon force, and the water in the reservoir is drained by the siphon force. When the siphon force is fully applied to the siphon drainage pipe, the amount of wastewater treatment becomes larger than the amount of inflow into the reservoir, and the water level in the reservoir decreases.

  In the second half of the siphon drainage, the water level in the storage part drops and the opening of the bypass pipe comes out of the water surface. For this reason, the bypass pipe sucks only air and the siphon drain pipe sucks only water from the inside of the storage section. Therefore, the siphon drain pipe does not absorb water and air simultaneously from the inside of the storage section, and noise such as zoom noise is not generated. Then, the siphon force is weakened, and the amount of wastewater treated and the amount of inflow into the reservoir 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. Thus, in the siphon drainage system of the present invention, when a bypass pipe is arranged from the storage part in addition to the siphon drain pipe, noise during drainage can be reduced.

As described above, the siphon drain pipe is connected to the bottom surface of the storage part or a portion close to the bottom surface of the side surface, but the opening of the bypass pipe is located higher than the connection part of the siphon drain pipe in the storage part. It is provided and is connected to the side surface over the side surface of the storage part. More specifically, the bypass pipe extends to a position higher than the siphon drain pipe, and then has a bent portion, and further extends downward from the bent portion to the bypass opening (claim 8 ). Include a reverse groove shape, an inverted U shape, an inverted V shape, and the like.

  A plurality of siphon drainage pipes may be connected to each unit reservoir, but in this case, it is not always necessary to install bypass pipes in all of these siphon drainage pipes.

  Of course, a water tank capable of storing a large amount of drainage is used for the storage unit, but a conventional gradient drainage pipe, a large-diameter drainage pipe, or the like that plays such a role can also be used. As described above, the shape and structure of the storage portion are not particularly limited, and may be of a vertically long shape, a horizontally wide shape, or a boat shape. is there. Furthermore, it is not necessary that the partitioning part is standing vertically, and it is possible to change the capacity of the storage part partitioned by making it oblique.

  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 reservoir, and 2 is a drain pipe from a watering device (not shown). Reference numeral 3 denotes, for example, a 20φ siphon drain pipe, and the storage portion 1 has a peripheral edge 1a and a bottom portion 1b, and is normally closed by a lid, which is not shown. The siphon drain pipe 3 is connected to the bottom 1b of the reservoir 1 and is laid on the slab 4 with no gradient. The tip of the siphon drainage pipe 3 is a pipe that joins a drainage stand pipe (not shown) with a head difference Hs to produce a siphon force.

  And the inside of the storage part 1 is divided into two chambers 1A, 1B (unit storage part) by a partition wall 1c having a lower height than the peripheral edge 1a. For this reason, the unit storage parts 1A, 1B have a height. The top part of the low partition wall 1c is a communication part 1d. And the siphon drain pipe 3 is an example separately provided in unit storage part 1A, 1B. In addition, although not illustrated, it cannot be overemphasized that the unit storage part 1A, 1B can be equipped with a plurality of siphon drain pipes.

  Therefore, when the waste water from the appliance flows into the unit reservoir 1A, it flows into the siphon drain pipe 3 provided on the 1A side, but water is accumulated in the unit reservoir 1A while the siphon is not activated. Become. And if the water level becomes more than the height 1dh of the communication part 1d comprised in the top part of the partition wall 1c, it will cross over this partition member 1c and will flow in in the adjacent unit storage part 1B. However, if the height 1dh to the communication portion 1d formed by the partition member 1c is equal to or less than the siphon activation Hp, the flow only overflows into the adjacent unit storage portion 1B. After that, siphon activation occurs only when the total water level in the storage unit 1 becomes equal to or higher than the siphon activation Hp. Even if the partition member 1c having a height equal to or lower than the siphon activation Hp is provided, the storage unit 1 is simply divided into two, and the siphon activation is the same even without the partition member 1c. It will be meaningless.

  On the other hand, when the height 1dh of the communication portion 1d configured by the partition member 1c is higher than the siphon activation Hp, when the drainage pipe 2 drains the unit storage portion 1A, the communication portion 1d is stored in the unit storage portion 1A. Before water overflows the top 1d of the partition member 1c, water pressure is applied from the rear end side of the siphon drain pipe 3, and siphon generation occurs early.

  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 storage unit 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 siphon drain pipe 3, then has a bent portion, further extends downward from the bent portion to the bypass opening 11, and overcomes the side surface of the storage portion 1 to form a reverse groove. And finally connected to the siphon drain pipe 3 (claim 8 ). The diameter 10a of the bypass pipe 10 is usually 20A, 16A, 13A or the like, 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 siphon drain 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 siphon drainage pipe 3 and the storage portion 1 is arbitrary, but the interval 10b is preferably as short as possible from the viewpoint of workability, workability at the time of inspection, and specifically 100 cm. 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.

  If the function of the bypass pipe 10 is mainly described here, when the waste water from the instrument flows into the storage part 1, it flows into the siphon drain pipe 3, but water is stored in the storage part 1 while the siphon is not activated. It will accumulate. 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 siphon drain pipe 3 and the bypass pipe 10. However, when the water level in the storage unit 1 is lowered to 10d, air is sucked from the bypass pipe 10, but the siphon drain pipe 3 is in a state where the siphon is activated at full flow. 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 siphon drainage pipe 3 even when the siphon is cut off.

  For this reason, while the siphon is being activated, air is not sucked from the siphon drain pipe 3, and there is no noise of noise, and furthermore, the noise of gobogobo caused by entraining air at the end of the siphon is reduced. Become.

  FIG. 3 is a side view showing a modification of the second embodiment of the present invention. In this example, the bent portion of the bypass pipe 10 penetrates the side surface of the storage section 1 to form a reverse groove shape, and the configuration of the storage section 1 and the bypass pipe 10 is a compact example.

  FIG. 4 is a perspective view showing a third embodiment of the present invention. In other words, in this example, the interior of the storage portion 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. Of course, the height 1eh to the communication hole 1e is higher than the siphon activation Hp.

  FIG. 5 is a perspective view showing a fourth embodiment of the present invention. That is, in this example, two storage parts 1 and 1 are provided side by side, and are communicated by a communication pipe 1f in the vicinity of a lid part (not shown) of each storage part. 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 storage part side when there is an obstacle such as a pillar at the position where the storage part is installed. In this example, the height 1fh to the communication pipe 1f is naturally larger than the siphon activation Hp.

  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.
