Description

  The present invention relates to a connection system for siphon drainage, and particularly relates to a connection system for siphon drainage used for drainage of a kitchen or the like.

  In recent years, siphon drainage systems have been proposed in place of conventional gradient drainage systems. The outline of this siphon drainage system consists of a drainage stand, a horizontal pulling pipe from a watering device, and a merging section having a head of 50 cm or more, and the horizontal pulling pipe does not join the other pipe as it is. It is a drainage system connected to the junction. And the water in a horizontal draw pipe is a system which drains the water in a horizontal draw pipe by generating a siphon force by the amount of the water head difference. However, the present situation is that no connection system for siphon drainage such as a kitchen that generates a large amount of drainage at a time has been developed so far.

  In the following, the present invention will be described mainly using kitchen drainage as a representative example, and a two-pipe system has been proposed for kitchen drainage in a siphon drainage system. However, the connection system is constructed using existing piping technology, and a plurality of increasers and redeusers must be used, the workability in the assembly is complicated, costly, and many There is a concern about the water leakage coming from assembling the parts.

  In order to improve this point, the present inventor has already provided a connection system for kitchens suitable for new siphon drainage. The content of the proposal is a system that connects a kitchen and two horizontal pipes, and has a bottomed cylindrical base connected to a drain pipe from the kitchen, and is directed in the same direction from the cylindrical base. The two narrow cylinders are connected to each other, and are formed at different positions on the top and bottom of the cylindrical base body.

  FIG. 1 is a partially cut side view of the proposed siphon drainage kitchen connection system. Reference numeral 11 denotes a bottomed cylindrical base body connected to a drain pipe 12 from a kitchen (not shown), and reference numerals 13 and 14 denote two small-diameter cylindrical bodies to which a horizontal pulling pipe is connected. It is formed to protrude in the same direction at different heights. In the figure, reference numerals 15 and 16 denote horizontal pulling pipes, and the upper pipe 15 is installed with a slight gradient.

  In such a connection system, when a large amount of drainage is made at once, the drainage is received by the cylindrical base 11, and the two horizontal pulling tubes 15 and 16 are drained by the co-siphon force. In other words, when draining the drainage water, the upper pipe 15 and the lower pipe 16 flow in full flow while demonstrating the siphon, thereby ensuring the necessary amount of drainage.

  On the other hand, at the time of continuous drainage, siphon drainage is performed only with the lower pipe 16, but drainage is performed using the upper pipe 15 immediately after the drainage is started. However, the upper pipe 15 is used only immediately after the start of drainage and is not used immediately. At that time, when the horizontal pipes 15 and 16 are made non-gradient as in the conventional siphon drainage system, water may remain in the upper pipe 15. However, the excessive siphon force (negative pressure) generated in the lower pipe 16 tends to suck air from the trap in the kitchen or the upper pipe 15, and in particular, when water remains in the upper pipe 15, The water and air in 15 will be sucked in simultaneously. For this reason, the drainage noise called zooming by simultaneously sucking water and air is brought about.

  For this reason, as described above, the upper pipe 15 is provided with a gradient so that the water remaining in the upper pipe 15 flows in the direction of the vertical pipe by this gradient. The inside can be emptied, and excessive siphon force generated in the lower pipe 16 is eliminated by sucking only air from the upper pipe 15. That is, since air is not sucked from the trap side, the drainage noise is reduced. Moreover, since excessive siphon force (negative pressure) is no longer applied to the trap side, it is possible to prevent the seal water from running out.

  In this way, the purpose of providing the upper pipe is not only to increase the drainage capacity, but also to eliminate the drainage noise due to the negative pressure of the lower pipe. It can be said that it is multipurpose.

  The above-described proposed connection system reduces the occurrence of water leakage because a new connection system is configured without using a large number of conventional increasers and reducers. However, there is a further improvement. That is, in practice, the purpose of the two pipes is not only for increasing the drainage capacity, but also for the purpose of eliminating drainage noise due to the negative pressure of the lower pipe, and the present invention is effective for these various purposes. A connection system to be achieved is provided.

  The gist of the present invention is a siphon drainage connection system for connecting a drain pipe from a kitchen or the like and two horizontal pipes, a bottomed cylindrical base body connected to the drain pipe, and the cylindrical base body The two pipes to which the horizontal pipes are connected, and the siphon end timings of the two horizontal pipes are different, and the pipe diameters of the horizontal pipes are different. It is the connection system for siphon drainage characterized by the above.

  The present invention has the above-described configuration. By further improving the invention already proposed by the present inventor and changing the pipe diameter of the horizontal pipe, the drainage capacity can be increased or negatively increased. It was possible to provide a connection system that can eliminate drainage noise due to pressure.

  In order to explain the present invention, the conventional siphon drainage is first added. Although there was a siphon drainage system using two horizontal pipes, the pipe diameter is the same size as that of one pipe. there were. That is, the condition for requiring two pipes is basically to increase the wastewater treatment capacity by using two pipes when the capacity is insufficient. This connection was made.

  However, the benefits of using two pipes are not only to solve the shortage of wastewater treatment capacity as described above, but also to prevent multiple seals and drainage noise, and to speed up the siphon start time. There is.

  However, the present inventor has reached the present invention from the knowledge that, in pursuit of the function of two pipes, the effect is further increased by changing the pipe diameter of the pipes in order to achieve the respective purposes. . In other words, if two pipes are installed with the same pipe diameter, the functions of the two pipes are not necessarily utilized to the fullest extent. It was with me.

  The present invention, when carrying out siphon drainage with two pipes, is intended to make the diameter of the two pipes different depending on the intended use, and to maximize the function of the two pipes, For example, the diameter of the two horizontal pipes used according to the purpose, such as the purpose of increasing the treatment flow rate at the time of sinking and the purpose of draining out of drainage noise during continuous drainage, such as a kitchen, is different. is there.

  In the present invention, a means is adopted in which the siphon end timing is different between the two pipes installed on the cylindrical base and the horizontal pipe connected thereto. As an example of such means, it is the simplest means to install the tubular body installed on the cylindrical base body with a step difference in the vertical direction, and the upper pipe is slightly delayed in the siphon start time and the siphon end time. It will be faster than the lower pipe.

  Of course, the means for making the siphon end time different is not limited to the above means, and the inside of the cylindrical base is divided into two rooms by a separation wall, and the upper part of the separation wall is opened and the two rooms are opened. The two pipes are installed separately in two rooms, and the drainage from the kitchen can be stored in one room. Needless to say, you can. In this case, the two pipe bodies can be installed at substantially the same horizontal position of the cylindrical base.

  Hereinafter, the present invention will be described in more detail with reference to examples. In addition, as a means for making the siphon start time and end time different, a description will be given using a means in which a tubular body installed on a cylindrical base is provided with a step difference in the vertical direction.

  FIG. 2 is a front view of a siphon connection system showing a first example of the present invention, and FIG. 3 is a side view thereof. This example is a preferred example when the purpose is to draw air from the upper tube instead of from the trap in response to excessive siphon. In the figure, reference numeral 1 denotes a bottomed cylindrical base body to which a drain pipe 2 from a kitchen (not shown) is connected. Reference numerals 3 and 4 denote two small-diameter cylinders to which the horizontal pulling pipes are connected, and are formed so as to protrude in the same direction from the cylindrical substrate 1 with different vertical heights. 5 and 6 are horizontal pipes connected to the cylinders 3 and 4 respectively, and are laid on the floor slab 7 with no gradient.

  In this example, for the purpose described above, the lower pipe (horizontal drawing pipe) 6 in the joint is thickened to increase the processing capacity of the lower pipe 6, and the upper pipe 5 slowly supplies air after completion of drainage or during continuous drainage. Since it is enough to suck, it should be constructed with a tube that is thinner than usual.

  FIG. 4 is a front view of a siphon connection system showing a second example of the present invention, and FIG. 5 is a side view thereof. In this example, in a watering device where the time until siphoning starts is an important factor, such as drainage of a unit bath, the pipe 6 is filled with water by reducing the diameter of the lower pipe 6. What is necessary is just to shorten time to do and shorten siphon start time. In addition, as the main role of the upper pipe 5 is to release air in the trap (not shown) to speed up the start of siphoning. By making the upper pipe 5 thicker, air in the trap can be easily released, and the siphon start time Can be shortened.

  The present invention is as described above, and the function provided by the two pipes can be more effectively exhibited by changing the pipe diameter, not only in the kitchen, but also in the unit bath, washing machine, wash basin, It can be widely used for joints of watering devices such as sinks where a large amount of drainage is planned at a time, and its utility value is extremely high.
