Description

[Technical Field]

[0001] The present invention relates to a vertical drain trap that is arranged along the vertical direction. [Background technology]

[0002] BACKGROUND ART Conventionally, a vertical drain trap is known that is provided in a drainage path that drains liquid into a sewage manhole and prevents backflow of polluted air, odors, pests, and the like (see, for example, Patent Document 1).

[0003] The vertical drain trap described in Patent Document 1 includes an L-shaped tubular wastewater inlet connected to the bottom of a washbasin or hand basin, a straight tubular main body connected to the downstream end of the wastewater inlet and with an outlet on the bottom, and a movable valve attached to the main body. The movable valve is configured to close the wastewater inlet by attracting a magnet attached to the main body with an iron piece attached to a valve stem supported by a lid attached to the top of the main body. This vertical drain trap is designed so that when the fluid pressure of the liquid exceeds the force of attraction of the iron piece to the magnet, the movable valve moves to the right, allowing the liquid in the wastewater inlet to flow into the main body and be discharged. The movable valve can also be removed together with the lid for cleaning. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-250911 Summary of the Invention [Problem to be solved by the invention]

[0005] The vertical drain trap described in Patent Document 1 is installed at the bottom of a washbasin or the like, and moves the movable valve using the water pressure of a large amount of liquid. However, air conditioner drains, for example, contain a small amount of liquid, so the water pressure is low and the movable valve does not move, which may result in the desired drainage performance not being achieved. Furthermore, air conditioner drain piping is sometimes installed in narrow spaces, so it may not be possible to install it with a structure combining an L-shaped pipe and a straight pipe, as with the vertical drain trap described in Patent Document 1. Furthermore, while the movable valve of the vertical drain trap described in Patent Document 1 can be removed and cleaned together with the lid, magnets and other elements installed in the main body require the user to reach inside the main body to clean it, which poses maintenance issues.

[0006] Therefore, there is a demand for a vertical drain trap that is easy to maintain and compact. [Means for solving the problem]

[0007] The characteristic configuration of the vertical drain trap of the present invention is that it comprises a main body case arranged in the vertical direction and having an inlet pipe section through which liquid flows in and an outlet pipe section through which the liquid is discharged, and a valve housing provided between the inlet pipe section and the outlet pipe section, a valve body that can abut from below against a valve seat formed in the inlet pipe section, a magnet mechanism that moves the valve body upward, and a guide member that guides the downward movement of the valve body under the weight of the liquid and the upward movement of the valve body by the magnet mechanism, and is contained inside the valve housing, and the valve housing has an opening formed therein that allows at least the valve body and the magnet mechanism of the valve unit to be removed from a direction intersecting the vertical direction.

[0008] This configuration includes a main body case with an inlet pipe, a valve housing, and an outlet pipe arranged vertically, which allows for a narrower width when connecting to an existing vertical pipe. This allows for a vertical drain trap to be connected even in a narrow space, such as the drain pipe of an air conditioner.

[0009] In addition, with this configuration, the valve element, which is moved upward by the magnet mechanism, contacts the valve seat of the inlet pipe from below, and the valve element is guided by the guide member and moves downward due to the weight of the liquid. Therefore, the flow direction of the liquid through the inlet pipe and the movement direction of the valve element are the same. In other words, even when there is not a large amount of liquid flowing, it is possible to ensure the force required to open the valve element by the weight of the liquid. As a result, the desired drainage performance can be achieved even with small amounts of liquid, such as air conditioner drain.

[0010] Furthermore, the valve housing of this configuration has an opening that allows the valve body and magnet mechanism of the valve unit to be removed from the direction intersecting the vertical direction, so not only the valve body but also the magnet mechanism can be removed and cleaned. Furthermore, since the valve unit is removed from the side of the main body case, which is arranged vertically, the valve unit can be removed from the opening without being obstructed by the piping that runs vertically. In this way, the vertical drain trap of this configuration is easy to maintain and compact.

[0011] Another characteristic feature is that the entire valve unit is configured to be removable from the opening.

[0012] As in this configuration, if the entire valve unit is removed from the opening, the guide member can also be cleaned, making maintenance even easier.

[0013] Another characteristic feature is that the opening includes an opening pipe portion that is inclined upward from a direction perpendicular to the up-down direction.

[0014] As in this configuration, if the opening pipe section is inclined upward rather than perpendicular to the vertical direction, liquid will not flow back from the inlet pipe section to the opening pipe section, and drainage will be smooth even during maintenance.

[0015] Another characteristic feature is that the guide member includes a tubular portion formed in a cylindrical shape, the valve body includes a movable portion that is inserted into the tubular portion and a hemispherical valve portion that is connected to the movable portion, and an annular sealing material that abuts against the valve seat is fixed to the surface of the valve portion.

[0016] By fixing the annular seal to the surface of the valve portion as in this configuration, the annular seal can be cleaned or replaced when the valve unit is removed, thereby maintaining the backflow prevention mechanism for preventing contaminated air, odors, pests, etc. for a long period of time.

[0017] Another characteristic feature is that the guide member includes a plurality of arms extending outward from the lower end of the tubular portion and a circular ring portion connecting the ends of the arms, and the circular ring portion is engaged with the discharge pipe portion.

[0018] With this configuration, it is possible to discharge liquid from between the multiple arms toward the discharge pipe section, and because the annular section is designed to engage with the discharge pipe section, the structure of the valve unit is simple and manufacturing costs can be reduced.

[0019] Another characteristic feature is that the magnet mechanism has a first magnet provided on the valve body and a second magnet of the same polarity as the first magnet provided on the guide member.

[0020] By providing a first magnet and a second magnet that repel each other by utilizing the valve body and the guide member as in this configuration, the device can be made compact. [Brief explanation of the drawings]

[0022] Hereinafter, an embodiment of the drain trap according to the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0023] As shown in Figures 1 and 2, the vertical drain trap X includes a resin main body case 1 arranged along the vertical direction, and a valve unit 2 housed in the main body case 1. The main body case 1 has an inlet pipe section 11 into which liquid flows, an outlet pipe section 12 from which liquid is discharged, and a valve housing 13 provided between the inlet pipe section 11 and the outlet pipe section 12. In this embodiment, the inlet pipe section 11, the outlet pipe section 12, and the valve housing 13 are integrally formed. In the following description, the direction of gravity is assumed to be the downward direction and the opposite direction to that is assumed to be the upward direction; however, the main body case 1 may be arranged at an angle as long as the inlet pipe section 11 is on the upper side and the outlet pipe section 12 is on the lower side relative to the valve housing 13.

[0024] As shown in Figure 2, the valve unit 2 has a resin valve element 21 that can close the inlet pipe section 11 from below, a resin guide member 22 that guides the up and down movement of the valve element 21, and a magnet mechanism 23 that moves the valve element 21 upward. This valve unit 2 is housed in a valve housing 13 of a main body case 1. The main body case 1, the valve element 21, and the guide member 22 are made of a weather-resistant resin such as polycarbonate. Furthermore, it is preferable that the main body case 1 is transparent, and that the valve element 21 and the guide member 22 have a color (e.g., blue) that can be distinguished from the valve housing 13. Here, "transparent" means a state in which the interior of the valve housing 13 can be seen through, and includes colorless transparency, colored transparency, and also translucence.

[0025] 1 and 2, an opening 13A through which the valve unit 2 can be removed in a direction intersecting the vertical direction is formed in the valve housing 13 between the inlet pipe 11 and the outlet pipe 12. In this embodiment, the opening 13A includes an opening pipe 13a that protrudes outward from the main body 13B of the valve housing 13, and a cover member 14 that closes the opening pipe 13a. The opening pipe 13a is inclined upward relative to the direction perpendicular to the vertical direction.

[0026] The inlet pipe section 11 has a first connecting pipe 11a connected to the upstream first drain pipe 31, and a first tapered pipe 11b connected to the first connecting pipe 11a and increasing in diameter toward the valve housing 13. The outlet pipe section 12 has a second connecting pipe 12a connected to the downstream second drain pipe 32, and a second tapered pipe 12b connected to the second connecting pipe 12a and increasing in diameter toward the valve housing 13. The main body section 13B of the valve housing 13 is formed in a cylindrical shape that connects the first tapered pipe 11b and the second tapered pipe 12b, and an accommodation space S that accommodates the valve unit 2 is formed inside.

[0027] A flow rectifying plate 11b2 having a circular hole formed in the center is fixed to the end of the first tapered tube 11b facing the valve housing 13. The outer periphery of the circular hole in the flow rectifying plate 11b2 forms a valve seat 11b1 against which the valve element 21 can abut from below. In this embodiment, the flow rectifying plate 11b2 is fixed to the end of the first tapered tube 11b facing the valve housing 13. The valve seat 11b1 may be formed of a polygonal hole or the like, and is not particularly limited as long as it has a shape that allows liquid to flow through. The flow rectifying plate 11b2 may also be engaged with the end of the first tapered tube 11b facing the valve housing 13. In this case, the user can hook their finger into the circular hole that serves as the valve seat 11b1 of the flow rectifying plate 11b2 and remove the flow rectifying plate 11b2 for maintenance.

[0028] The opening pipe portion 13a is an inclined pipe surrounded by an upper wall 13b1, a lower wall 13b2 longer than the upper wall 13b1, a first end 13b3 connected to the main body 13B of the valve housing 13, and a second end 13b4 having a male thread for threading the lid member 14. The opening pipe portion 13a is inclined upward relative to a direction perpendicular to the vertical direction by forming the lower wall 13b2 longer than the upper wall 13b1. The second end 13b4 of the opening pipe portion 13a is inclined relative to the inlet pipe portion 11 and the outlet pipe portion 12 by connecting the lower wall 13b2 and the upper wall 13b1. In other words, the lid member 14 threaded onto the second end 13b4 is also inclined, making it easy to recognize the lid member 14 from the front side of the vertical drain trap X. A sealant Ka is disposed at the second end 13b4 of the opening pipe portion 13a, and is tightly fitted to the lid member 14 by threading it.

[0029] The cover member 14 is circular in front view and can be attached to the opening pipe portion 13a by threading it onto a male thread formed on the outer peripheral surface of the second end 13b4 of the opening pipe portion 13a. The outer periphery of the cover member 14 is formed with a plurality of equally spaced protrusions 14a protruding radially outward. The user can hook their fingers onto these protrusions 14a to easily attach the cover member 14 to the opening pipe portion 13a. A reflector 14b (e.g., reflective tape) is attached to the outer periphery of the cover member 14 along the entire periphery. This allows an operator to easily identify the location of the vertical drain trap X by shining light onto the reflector 14b when storing the vertical drain trap X in a maintenance box. Since various other paths may be installed in addition to the drainage path in which the vertical drain trap X is installed, for example, the reflector 14b on the vertical drain trap X may be red and yellow reflectors may be provided on the members on the other paths, thereby color-coding the reflectors for each path.

[0030] As shown in FIGS. 2 to 4, the valve element 21 includes a movable portion 21a that is fitted onto a cylindrical portion 22a of a guide member 22 (described later) and a hemispherical valve portion 21b that is integrally connected to the movable portion 21a. The movable portion 21a is cylindrical, with one end fitted onto the cylindrical portion 22a of the guide member 22 and the other end connected to the valve portion 21b. The valve portion 21b has a circular flat surface 21b1 to which the other end of the movable portion 21a is connected and a hemispherical surface 21b2 that curves from the outer periphery of the circular flat surface 21b1. A first magnet 23a of a magnet mechanism 23 (described later) is fixed to the center of the circular flat surface 21b1. An annular seal Kb, such as an O-ring, that can abut against a valve seat 11b1 of the inlet pipe portion 11 is fixed to the hemispherical surface 21b2 (the surface of the valve portion 21b) in a state where it is fitted into an annular groove. The valve element 21, which can come into contact from below with the valve seat 11b1 formed in the inlet pipe portion 11, is closed when the annular seal Kb comes into close contact with the valve seat 11b1. The annular seal Kb is formed with a shape and width that allows it to come into close contact with the valve seat 11b1.

[0031] The guide member 22 guides the downward movement of the valve disc 21 under the weight of the liquid and the upward movement of the valve disc 21 due to the magnet mechanism 23. The guide member 22 includes a cylindrical tubular portion 22a with a bottom, multiple (four in this embodiment) arm portions 22b extending outward from the bottom end of the tubular portion 22a, and an annular portion 22c connecting the ends of the multiple arm portions 22b. The bottom of the tubular portion 22a has a magnet holding member 22a1, and a second magnet 23b of the magnet mechanism 23 (described later) is fixed to the center of the magnet holding member 22a1. The multiple arm portions 22b are spaced apart from each other at equal intervals (90-degree intervals in this embodiment) in the circumferential direction, and the space between adjacent arm portions 22b forms a liquid discharge space. The annular portion 22c is engaged with the end of the second tapered tube 12b of the discharge pipe portion 12 on the valve housing 13 side. The engagement between the annular portion 22c and the second tapered tube 12b is constituted by the engagement of the annular portion 22c with the inward protruding portion of the second tapered tube 12b, and is not particularly limited as long as the structure can maintain the axis of the guide member 22.

[0032] 2 and 4, the magnet mechanism 23 has a first magnet 23a provided on the valve disc 21 and a second magnet 23b provided on the guide member 22. As described above, the first magnet 23a is fixed at the center position of the circular flat surface 21b1 of the valve disc 21, and the second magnet 23b is fixed at the center position of the magnet holder 22a1 of the guide member 22. The circular flat surface 21b1 of the valve disc 21 and the magnet holder 22a1 of the guide member 22 are arranged coaxially with the same poles facing each other. Therefore, due to the repulsive force between the first magnet 23a and the second magnet 23b, when the valve unit 2 is accommodated in the accommodation space S of the valve housing 13, the valve portion 21b abuts against the valve seat 11b1, and the annular seal member Kb is tightly attached to the valve seat 11b1, thereby closing the inlet pipe portion 11. On the other hand, when a predetermined amount of liquid flowing in from the inlet pipe section 11 accumulates on the straightening plate 11b2, the valve element 21 moves downward against the repulsive force between the first magnet 23a and the second magnet 23b, and opens. When the valve element 21 opens, the liquid that has passed through the valve element 21 is discharged from the main body 13B of the valve housing 13 to the outlet pipe section 12, passing between the multiple arms 22b of the guide member 22.

[0033] As shown in FIG. 1 , in this embodiment, by hooking fingers around the lower portion of the valve portion 21b of the valve element 21 and the lower portion of the tubular portion 22a of the guide member 22 and applying a force that counteracts the repulsive force of the magnet mechanism 23, the valve element 21 can be separated from the rectifying plate 11b2, allowing the entire valve unit 2 to be removed through the opening 13A (opening pipe portion 13a). In other words, the valve housing 13 has an opening 13A that allows the valve unit 2 to be removed in a direction intersecting the vertical direction. Therefore, not only the valve element 21 but also the guide member 22 and the magnet mechanism 23 can be removed and cleaned. Furthermore, because the valve unit 2 is removed from the side of the main body case 1, which is arranged vertically, the valve unit 2 can be removed through the opening pipe portion 13a without being obstructed by the drain pipes 31 and 32 that run vertically. Thus, the vertical drain trap X of this embodiment has a structure that facilitates maintenance.

[0034] In addition, in this embodiment, the main body case 1 is provided with the inlet pipe section 11, the valve housing 13, and the outlet pipe section 12, which are arranged in the vertical direction, so that it is possible to reduce the width when connecting to the existing drain pipes 31 and 32 that are also arranged in the vertical direction. Therefore, even if the drain pipes 31 and 32 of an air conditioner are installed in a narrow space, the vertical drain trap X can be connected.

[0035] Furthermore, in this embodiment, the valve element 21, which has been moved upward by the magnet mechanism 23, abuts against the valve seat 11b1 of the inflow pipe section 11 from below, and the valve element 21 is guided by the guide member 22 and moves downward due to the weight of the liquid, so that the flow direction of the liquid flowing through the inflow pipe section 11 and the movement direction of the valve element 21 are the same. In other words, even in a situation where a large amount of liquid is not flowing, it is possible to ensure a force to open the valve element 21 due to the weight of the liquid. As a result, the desired drainage performance can be achieved even with a small amount of liquid, such as air conditioner drain.

[0036] Furthermore, because the opening pipe portion 13a is inclined upward relative to the vertical direction, liquid does not backflow from the inlet pipe portion 11 to the opening pipe portion 13a, ensuring smooth drainage. In this embodiment, the annular seal Kb is fixed to the surface of the valve portion 21b, allowing the annular seal Kb to be cleaned or replaced when the valve unit 2 is removed. As a result, the backflow prevention mechanism for preventing contaminated air, odors, pests, etc. can be maintained for a long period of time. Furthermore, because liquid can be discharged toward the outlet pipe portion 12 through the multiple arms 22b, and the annular portion 22c is engaged with the outlet pipe portion 12, the structure of the valve unit 2 is simple, reducing manufacturing costs. Furthermore, the first magnet 23a and the second magnet 23b, which repel each other, are provided using the valve body 21 and the guide member 22, resulting in a compact device.

[0037] [Other embodiments]

[0038] (1) As shown in FIG. 5 , the guide member 22 of the valve unit 2 may have a threaded portion 22a2 at a position on the cylindrical portion 22a that is lower than the lower end of the movable portion 21a when the valve element 21 is in the closed state. In this embodiment, the annular portion 22c is fixed to the end of the second tapered tube 12b of the discharge pipe portion 12 that faces the valve housing 13. In this embodiment, after unscrewing the threaded portion 22a2, the valve element 21 and the magnet mechanism 23 can be separated from the rectifying plate 11b2 and removed through the opening 13A by hooking fingers on the lower portions of the valve portion 21b of the valve element 21 and the threaded portion 22a2, respectively, and applying a force that counteracts the repulsive force of the magnet mechanism 23. In other words, the valve housing 13 has an opening 13A between the inlet pipe portion 11 and the outlet pipe portion 12, through which at least the valve element 21 and the magnet mechanism 23 of the valve unit 2 can be removed in a direction intersecting the vertical direction. In this embodiment, the area of ​​the guide member 22 below the threaded portion 22a2 does not need to be removed from the opening 13A (opening pipe portion 13a), so the opening area of ​​the opening 13A can be reduced. The area of ​​the guide member 22 below the threaded portion 22a2 can be washed by inserting a hand through the opening 13A.

[0039] 6, the first magnet 23a may be disposed on the outer periphery of the circular flat surface 21b1 of the valve body 21, and the second magnet 23b may be disposed on the outer periphery of the magnet holding member 22a1 of the guide member 22. In this case, the movable portion 21a of the valve body 21 is inserted into the cylindrical portion 22a of the guide member 22.

[0040] (3) As shown in FIG. 7, the opening pipe portion 13a may be a threaded pipe having a male thread formed thereon for threading the cover member 14. Alternatively, the cover member 14 may be integrally formed with a solid pipe (not shown) having a female thread formed at its end, with the female thread of the solid pipe being threaded onto the opening pipe portion 13a. The opening pipe portion 13a is provided with a sealant Ka that adheres closely to a flat end surface 13b5 extending in the vertical direction, the same as the extension direction of the valve housing 13. By threading the cover member 14 onto the opening pipe portion 13a, the sealant Ka is compressed, thereby sealing off water. Alternatively, the cover member 14 may be configured to be unscrewed from the opening pipe portion 13a, allowing the current plate 11b2 to be removed for cleaning or replacement. In this case, the protruding dimension of the opening pipe portion 13a can be reduced, thereby further compacting the vertical drain trap X.

[0041] (4) The cover member 14 may be rectangular in plan view and press-fit into the opening pipe portion 13a of the valve housing 13. In this case, the cover member 14 can be easily attached and detached without providing a protrusion 14a on the outer periphery. In addition, since the opening width of the opening 13A for removing the guide member 22 can be made small, the width of the vertical drain trap X can be made compact.

[0042] (5) The valve unit 2 may further include a split-type sealed case that hermetically surrounds at least the boundary between the valve housing 13 and the inlet pipe 11. In this case, an air gap is formed between the sealed case and the valve housing 13 and the inlet pipe 11. This allows the gap to suppress condensation even when there is a temperature difference between the liquid flowing through the valve housing 13 and the outside air. Furthermore, it is preferable that the main body case 1 and the sealed case are transparent, and that the valve element 21 be a color (e.g., blue) that can be distinguished from the valve housing 13 and the sealed case. This allows an operator to visually confirm the position of the valve element 21 from outside the valve housing 13 when the valve unit 2 is installed in the accommodation space S of the valve housing 13. This makes it easy to check whether the valve element 21 is installed in the correct position and to check the degree of contamination of the valve element 21.

[0043] (6) In the above embodiment, the cover member 14 is configured to be attachable by screwing it to the opening pipe portion 13a, but the cover member 14 may be configured as a press-fit type, in which the cover member 14 is press-fitted into the opening pipe portion 13a and attached to the opening pipe portion 13a. In other words, the way in which the cover member 14 is attached to the opening pipe portion 13a can be changed as appropriate.

[0044] (7) The open pipe portion 13a in the above embodiment may be omitted, and the cover member 14 may be directly attached to the main body portion 13B of the valve housing 13. In this case, the vertical drain trap X can be made even more compact.

[0045] (8) In the above embodiment, the annular seal Kb is fixed to the surface of the valve portion 21b, but the annular seal Kb may be fixed to the valve seat 11b1. Also, an elastic member may be provided over the entire hemispherical surface 21b2 of the valve portion 21b, so that the entire hemispherical surface 21b2 is made of a sealant.
