Description

Siphon drainage system

The invention relates to a siphon drainage system.

Japanese Patent Laid-Open No. 2007-315036 discloses a siphon drainage system in which a temporary storage tank with drainage is connected between a water appliance and a siphon drainage pipe. The temporary storage tank is arranged in the under-floor space between the floor and the floor.

The siphon drain pipe has a horizontal pipe (horizontal pipe) and a vertical pipe that allows the drainage from the horizontal pipe to flow downward. The drainage will move in the horizontal pipe and then enter the vertical pipe. When the vertical pipe becomes full, siphon force will be generated due to the potential energy of the drainage falling in the vertical pipe to introduce the subsequent drainage into the vertical pipe and discharge .

At this time, if the horizontal pipe is long, it takes more time until the drainage moving in the horizontal pipe reaches the vertical pipe to generate siphoning force. In addition, when there is a large amount of drainage from the water appliance, the drainage may remain on the upstream side of the horizontal pipe. The temporary storage tank described in the above-mentioned past example is used to suppress the above stagnation.

However, the temporary storage tank needs to have a certain height, and it must correspond to this height to ensure the space under the floor. In order to seek a lower floor, it is expected that the temporary storage tank is not required or the temporary storage tank is miniaturized.

The object of the present invention is to reduce the time delay from the start of drainage from a water appliance until the generation of siphon force, and to suppress the retention of drainage on the upstream side of the horizontal pipe.

The first aspect of the siphon drain system has: a first drain pipe connected to the water appliance; a drain well connected to the downstream side of the first drain pipe; a second drain pipe connected to the downstream side of the drain well; siphon The horizontal pipe of the drain pipe is connected to the downstream side of the second drain pipe; the siphon drain The vertical pipe of the pipe is connected to the downstream side of the horizontal pipe and will cause the drainage from the horizontal pipe to flow downward; and the water supply section is connected to the boundary portion of the horizontal pipe and the vertical pipe or the vertical pipe, and Irrigation water can be supplied to the standpipe.

In this siphon drainage system, irrigation water can be supplied to the vertical pipe of the siphon drainage pipe by the water supply section. Even if the drainage from the water appliance moves in the horizontal pipe of the siphon drain pipe and has not yet reached the stand pipe, the siphon force is still generated because the irrigation water is supplied to the stand pipe to make the stand pipe full. Once the siphon force is generated, the horizontal pipe will generate negative pressure to introduce the air between the drainage and irrigation in the horizontal pipe into the vertical pipe, and the drainage in the horizontal pipe will also be introduced into the vertical pipe. Therefore, compared with the case where no irrigation water is supplied to the standpipe, the time from the start of drainage from the water appliance to the generation of siphon force can be shortened. Therefore, even in the case where the horizontal pipe is long, or the amount of drainage from the water appliance is large, there is still no drainage remaining on the upstream side of the horizontal pipe.

The second aspect is in the siphon drainage system of the first aspect. The second drainage pipe system is provided with a first sensor that will detect the drainage passing through the second drainage pipe; The signal of the first sensor controls the operation of the water supply section; when the first sensor detects that there is drainage in the second drain pipe, the control section will cause the water supply section to operate to supply irrigation water to The riser.

In the siphon drainage system, the second drainage pipe connected between the drainage trap and the horizontal pipe is provided with a first sensor that detects the drainage passing through the second drainage pipe. When the first sensor detects that there is drainage in the second drainage pipe, the control section will cause the water supply section to operate to supply irrigation water to the standpipe. Therefore, since the irrigation water can be supplied to the vertical pipe at an appropriate time when the drainage reaches approximately the horizontal pipe of the siphon drainage pipe, it is less likely to cause drainage to stay.

The third aspect is that in the siphon drainage system of the second aspect, the first drainage pipe is provided with a second sensor that detects the water level of the first drainage pipe; when the second sensor detects the When the water level of the first drain pipe exceeds a certain value, the control unit will issue an alarm.

In the siphon drainage system, the first drainage pipe connected between the water appliance and the drainage well is provided with a second sensor that detects the water level of the first drainage pipe. When the second sensor detects that the water level of the first drain pipe exceeds a certain value, the control unit will issue an alarm. When the water level of the first drain pipe exceeds a certain value, the siphon drain pipe may be generated due to the retention of the drain water on the upstream side of the drain well. Poor raw drainage (failure). In this siphon drainage system, the user can be informed of the occurrence of the above-mentioned drainage failure by an alarm.

The fourth aspect is that in the siphon drainage system of the third aspect, the measurement log of the first sensor, the measurement log of the second sensor, and the issuance of the alarm are saved as data.

In this siphon drainage system, since the measurement log of the first sensor, the measurement log of the second sensor, and the issuance of an alarm are stored as data, the history of poor drainage in the siphon drainage pipe can be easily confirmed.

The fifth aspect is in the siphon drainage system of the fourth aspect, and the data is stored in the memory device through the network.

In this siphon drainage system, since the measurement log of the first sensor, the measurement log of the second sensor, and the data of the alarm are stored in the memory device through the network, it can occur in the remote detection of the siphon drainage pipe Of poor drainage, or confirm the history of poor drainage at the far end.

The sixth aspect is in the siphon drainage system of any one of the first to fifth aspects, the boundary between the horizontal pipe and the vertical pipe is provided with a connection port for connecting the piping of the water supply section; the piping It can be removed from this connection port.

In this siphon drainage system, since the piping of the water supply section can be removed from the connection port provided at the boundary between the horizontal pipe and the vertical pipe, the connection port can be removed by removing the piping of the water supply section from the connection port Used as a cleaning port for siphon drains. Therefore, when poor drainage occurs in the siphon drain, the siphon drain can be easily cleaned or checked in an emergency.

According to the siphon drainage system related to the present invention, the time delay from the start of the drainage from the water appliance to the generation of the siphon force can be reduced to suppress the retention of drainage on the upstream side of the lateral pipe.

In the following, a description will be given of the type for implementing the present invention based on the drawings.

[First embodiment]

First, the overall configuration of the siphon drainage system 10 according to this embodiment will be described. FIG. 1 is a schematic diagram showing the overall configuration of a siphon drainage system 10 related to this embodiment. The siphon drainage system 10 is a drainage system that utilizes siphon force to efficiently drain the water from the water appliance. The siphon drain system 10 includes a first drain pipe 31, a drain well 18, a second drain pipe 32, a horizontal pipe 21, a vertical pipe 22, and a water supply unit 40.

The siphon drainage system 10 is used in, for example, a multiple-floor housing complex. As shown in FIG. 1, the siphon drainage system 10 has a drainage riser 12 that allows drainage to flow downward. The drainage riser 12 extends in the vertical direction (longitudinal direction) of the housing complex and penetrates the floor slab 14 of each floor of the housing complex.

The kitchen sink 16 as an example of water appliance is provided on each floor of the assembly house. A drain 30 is provided at the bottom of the kitchen sink 16. The drain 30 is provided to open to the drain 16A provided at the bottom of the kitchen sink 16. The drain from the kitchen sink 16 will flow into the drain 30 through the drain 16A.

The first drain pipe 31 is connected to the drain portion 30 of the kitchen sink 16. The first drain pipe 31 extends in the vertical direction and extends downward from the drain portion 30. The drain trap 18 is connected to the downstream side of the first drain pipe 31. The drain well 18 is, for example, an S-shaped well. The second drain pipe 32 is connected to the downstream side of the drain well 18. The second drain pipe 32 extends in the up-down direction, and extends from the downstream end of the drain well 18 downward to the vicinity of the upper surface of the floor 14.

The siphon drain pipe 23 is configured to include a horizontal pipe 21 and a vertical pipe 22. The horizontal pipe 21 is a pipe connected to the downstream side of the second drain pipe 32. The horizontal pipe 21 extends horizontally on the floor 14 without tilting. The drain flowing from the second drain pipe 32 into the horizontal pipe 21 flows laterally in the horizontal pipe 21.

The vertical pipe 22 is connected to the downstream side of the horizontal pipe 21, and causes the drainage to flow from the horizontal pipe 21 to the lower pipe. The vertical pipe 22 extends in the vertical direction (longitudinal direction) along the drain riser 12. Horizontal tube 21 Drainage etc. flowing into the vertical pipe 22 will fall downward, thereby generating siphoning force. A drain joint 50 that connects the downstream end of the vertical pipe 22 and the drain riser 12 is connected. The drain joint 50 causes the drain from the vertical pipe 22 to converge toward the drain riser 12. The inner diameter of the horizontal pipe 21 and the inner diameter of the vertical pipe 22 in the siphon drain pipe 23 are, for example, 20 mm, so that the drain water from the kitchen sink 16 can easily flow in a full water state.

The water supply unit 40 is connected to the boundary between the horizontal pipe 21 and the vertical pipe 22, or the vertical pipe 22, and is configured to supply priming water to the vertical pipe 22. Here, the boundary portion is not only the portion connecting the horizontal pipe 21 and the vertical pipe 22, but also includes the end portion upstream of the vertical pipe 22, that is, the downstream side of the horizontal pipe 21. In this embodiment, the connecting portion of the horizontal tube 21 and the vertical tube 22 is provided with a curved portion 44 (elbow tube or L-shaped tube) curved in an arc shape.

In the example shown in FIGS. 1 and 2, the lower end of the pipe 42 of the water supply unit 40 is connected to the upper end of the stand pipe 22. In other words, a pipe 42 is provided on an extension line upward of the vertical pipe 22. On the other hand, in the example shown in FIG. 3, the piping 42 is connected to the wiring direction with respect to the bent portion 44. The angle θ formed by the upstream side of the horizontal pipe 21 and the pipe 42 is an acute angle. As a result, the irrigation water can easily flow from the pipe 42 to the vertical pipe 22 (direction of arrow A), and cannot easily flow back toward the upstream side of the horizontal pipe 21 (direction of arrow B). This configuration is particularly effective when the irrigation volume is large.

In order to generate the siphon force early and suppress the backflow of the irrigation water toward the upstream side of the lateral pipe 21, it is preferable that the connection portion of the pipe 42 of the water supply section 40 to the siphon drain pipe 23 is as close as possible to the vertical pipe 22. In addition, as long as the siphon force can be generated by irrigation, the piping 42 of the water supply unit 40 may be connected below the upper end of the standpipe 22.

The water supply unit 40 is provided with a valve 46 that can switch the supply of irrigation water. The opening and closing of the valve 46 is controlled by a control unit 34 (FIG. 2) described later.

In FIG. 2, the second drain pipe 32 is provided with a first sensor 51 that detects the drain passing through the second drain pipe 32. As the first sensor 51, for example, a pressure sensor or a conductive sensor can be used. In addition, any sensor may be used as long as the first sensor 51 can detect the flow of drain water to the second drain pipe 32.

The detection position of the first sensor 51 is, for example, the lower end of the second drain pipe 32. This is because it is possible to easily detect when the drain water flows into the horizontal pipe 21 of the siphon drain pipe 23. In addition, the detection position of the first sensor 51 may be another position in the second drain pipe 32. Also, you can set A plurality of first sensors 51 are provided. In this case, the drain water remaining in the second drain pipe 32 may also be detected.

The siphon drainage system 10 additionally has a control section 34. The control unit 34 is a part that controls the operation of the water supply unit 40 (specifically, the opening and closing of the valve 46) based on the signal from the first sensor 51. When the first sensor 51 detects that there is drainage in the second drainage pipe 32, the control unit 34 will actuate the water supply unit 40 to supply irrigation water to the stand pipe 22. Specifically, the control unit 34 opens the valve 46 to supply the irrigation water to the stand pipe 22 through the pipe 42.

The piping 42 of the water supply unit 40 is connected to, for example, a water supply channel, but it is not limited to this, and may be connected to a water storage tank (not shown) for rainwater or the like. That is, the irrigation water is not only the water in the waterway, but also the stored water.

The first drain pipe 31 is provided with a second sensor 52 that can detect the water level of the first drain pipe 31. The second sensor 52 is connected to the control unit 34. When the second sensor 52 detects that the water level of the first drain pipe 31 exceeds a certain value, the control unit 34 will issue an alarm 36. The second sensor 52 is a sensor that can detect the drainage remaining in the first drainage pipe 31. As the second sensor 52, for example, a flow sensor or a laser sensor that can detect the height of the water surface can be used. In addition, any sensor may be used as long as the second sensor 52 is capable of detecting the drainage remaining in the first drainage pipe 31. The detection position of the second sensor 52 is, for example, the center portion of the first drain pipe 31 in the up-down direction.

In addition, the detection position of the second sensor 52 may be another position in the first drain pipe 31. In order to detect the drain water remaining in the first drain pipe 31 immediately, the detection position of the second sensor 52 is set to the lower portion of the first drain pipe 31. Furthermore, a plurality of second sensors 52 may be provided. By using the plural second sensors 52, it is possible to more accurately determine whether the drain is flowing or staying in the first drain pipe 31.

The measurement log of the first sensor 51, the measurement log of the second sensor 52, and the issue of the alarm 36 are stored as data. Specifically, the data is stored in the memory device 49 via the network 48. The memory device 49 may be located at a remote location away from the assembly house where the siphon drainage system 10 is installed, or within the assembly house. When the memory device 49 is installed at a remote location, the network 48 includes a WAN (Wide Area Network) such as the Internet. When the memory device 49 is installed in a housing complex, the network 48 is equivalent to a LAN (Local Area Network). In addition, instead of using the network 48, a memory device (not shown in the figure) may be provided in or near the control unit 34 to store data in the memory device.

(effect)

The configuration of the present embodiment is as described above, and its function will be described below. In FIG. 1, according to the siphon drainage system 10, the drained water from the kitchen sink 16 will first flow through the drain 30 in the first drain pipe 31, the drain well 18, and the second drain pipe 32, and then further in the siphon The non-inclined horizontal pipe 21 in the drain pipe 23 flows in the lateral direction. Then, the drainage will fall in the vertical pipe 22, and the siphon force is activated by the potential energy of the siphon head Hs in the vertical pipe 22. The drainage in the horizontal pipe 21 and the vertical pipe 22 of the siphon drainage pipe 23 will further induce drainage in the second drainage pipe 32 due to the siphon force to promote the drainage. Therefore, even if the horizontal pipe 21 does not incline downward toward the vertical pipe 22 side, drainage can be guided by the siphon force. In addition, the horizontal pipe 21 may have a downward slope that falls toward the vertical pipe 22 side.

In addition, in the present embodiment, the water supply unit 40 can supply the irrigation water to the vertical pipe 22 of the siphon drain pipe 23. Even if the drain from the kitchen sink 16 moves in the horizontal pipe 21 of the siphon drain 23 and has not yet reached the stand pipe 22, the siphon force will still be generated because the irrigation water is supplied to the stand pipe 22 to make the stand pipe 22 full. . Once the siphon force is generated, the horizontal pipe 21 will generate a negative pressure to introduce the air between the drainage and irrigation water in the horizontal pipe 21 into the vertical pipe 22, and the drainage in the horizontal pipe 21 will also be introduced into the vertical pipe 22. Therefore, compared with the case where the irrigation water is not supplied to the vertical pipe 22, or the irrigation water is supplied to the upstream side of the horizontal pipe 21 such as the second drain pipe 32, the generation of siphon force after the start of the drainage from the kitchen sink 16 can be shortened The time so far. Therefore, even when the horizontal pipe 21 is long, or when the amount of drainage from the kitchen sink 16 is large, the drainage does not remain on the upstream side of the horizontal pipe 21.

In addition, as shown in FIG. 2, in the present embodiment, the second drain pipe 32 connected between the drain well 18 and the lateral pipe 21 is provided with a first sensor that detects the drain passing through the second drain pipe 32器51. When the first sensor 51 detects that there is drainage in the second drainage pipe 32, the control unit 34 causes the water supply unit 40 to operate. Specifically, the valve 46 of the water supply unit 40 is opened by the control unit 34. Thereby, the irrigation water is supplied to the stand pipe 22 from the pipe 42. Therefore, since the water can be supplied to the vertical pipe 22 at a proper time when the drainage reaches the horizontal pipe 21 of the siphon drainage pipe 23, it is less likely to cause drainage to stay.

Further, in the present embodiment, the first drain pipe 31 connected between the kitchen sink 16 and the drain well 18 is provided with a second sensor connected to the control unit 34 that detects the water level of the first drain pipe 31 52. When the second sensor 52 detects that the water level of the first drain pipe 31 exceeds a certain value, the control unit 34 will issue an alarm 36. When the water level of the first drain pipe 31 exceeds a certain value, the first drain pipe 31 on the upstream side of the drain well 18 may be drained, which may cause a poor drainage (failure) in the siphon drain pipe 23. In this embodiment, the alarm 36 can let the user know that the above-mentioned drainage failure has occurred.

In addition, in the present embodiment, since the measurement log of the first sensor 51, the measurement log of the second sensor 52, and the issuance of the alarm 36 are stored as data, the siphon drain 23 can be easily confirmed The resume of poor drainage. If the measurement log of the first sensor 51, the measurement log of the second sensor 52, and the data sent by the alarm 36 are stored in the memory device 49 via the network 48, the siphon drain 23 can be detected remotely Poor drainage occurred during the process, or confirm the history of poor drainage at the far end.

As such, according to the present embodiment, since the siphon force can be quickly generated by irrigation, a temporary storage tank (not shown in the figure) for preventing the retention of drainage is not required, or even a temporary storage tank is provided In this case, the temporary storage tank can still be miniaturized.

If there is less drainage from the kitchen sink 16, although it is possible that the standpipe 22 will not become full and no siphoning force is generated, according to this embodiment, even if there is less drainage from the kitchen sink 16, It can still produce siphon force quickly.

In the housing complex, since the piping space is provided with a water channel system, the water supply unit 40 can be configured by diverting piping from the water channel system. Therefore, it is not necessary to prepare a large space for installing the water supply unit 40.

[Second Embodiment Type]

In FIGS. 4 and 5, in the siphon drainage system 20 related to the present embodiment, the boundary portion of the horizontal pipe 21 and the vertical pipe 22 is provided with a connection port 54 for connecting to the pipe 42 of the water supply section 40. Specifically, a joint 56 with a cleaning port as an example of a boundary portion is provided between the downstream end of the horizontal tube 21 and the bent portion 44. The cleaning port in the joint 56 with the cleaning port also serves as the connection port 54. The joint 56 with a cleaning port has a joint body 58 and a cover 60. The connection port 54 is provided in the connector 体58. The connection port 54 is configured in a cylindrical shape, for example. The cover 60 is a component for closing the connection port 54 and can be attached to and detached from the joint body 58 by screw fitting.

The pipe 42 of the water supply unit 40 can be detached from the connection port 54. Specifically, as shown in FIG. 5, the lower end of the pipe 42 is inserted into the cover 60. As described above, since the cover 60 can be attached to and detached from the joint body 58, the pipe 42 can be connected to or removed from the connection port 54.

In the siphon drainage system 20, since the piping 42 of the water supply section 40 can be removed from the connection port 54 provided at the boundary between the horizontal pipe 21 and the vertical pipe 22, the piping 42 of the water supply section 40 is removed from the connection port 54 When removed, the connection port 54 can be used as a cleaning port for the siphon drain 23. Therefore, when poor drainage occurs in the siphon drain pipe 23, etc., the siphon drain pipe 23 can be easily cleaned or checked in an emergency response.

In addition, the configuration of the connection port 54 connected to the piping 42 of the water supply unit 40 is not limited to the above-mentioned configuration. For example, a three-way pipe joint (not shown) may be provided at the boundary between the horizontal pipe 21 and the vertical pipe 22. The pipe 42 is attached to and detached from the pipe joint.

Since the other parts are the same as those in the first embodiment, the same parts are given the same symbols in the drawings and the description is omitted.
