Description

  The present invention relates to a drainage system provided with a interceptor, and more particularly to a drainage system that receives drainage from a kitchen sink and the like, removes contaminants such as fats and oils contained in the drainage, and discharges it into sewage.

  Drainage discharged from kitchen sinks (sinks) in restaurants and light meal facilities contains oils and fats washed away from dishes and cooking utensils used for cooking. If it flows, it will be a major cause of clogging by adhering to the inner wall of the drain pipe or sewer pipe. In addition, fats and oils can be decomposed by bacteria in nature, but if the content in the wastewater increases, decomposition becomes difficult and the water quality deteriorates.

  For this reason, the n-Hex value (normal hexane extractable substance content) is defined as one of the indexes for regulating the content of fats and oils in the waste water. It is stipulated in the Pollution Control Law, the Sewerage Law, the Building Standards Law, and local regulations. Along with this, it is obliged for restaurants to install drainage facilities (for example, grease interceptors) for collecting and removing fats and oils from kitchen wastewater.

  Such a grease interceptor is installed, for example, in a lower space of a kitchen sink, and generally receives drainage from the sink, and uses the difference in specific gravity of oil and water to float the oil and fat on the surface of the water and separate the water. (See the following patent document).

No. 7-534 JP 2000-220192 A

  By the way, in the conventional interceptor, in order to remove the fats and oils accumulated in the equipment or to maintain a good sanitary state, a cleaning work is frequently required, and the workability is required. For this reason, in the interceptor of the said patent document 1, even when an upper space is restrict | limited by a sink by making the partition provided in the inside of an apparatus bendable, it is easy to extract the partition and to facilitate the cleaning work. . However, the interceptor described in Patent Document 1 has to work under the sink and has a poor workability.

  On the other hand, according to the interceptor described in Patent Document 2, the interceptor can be pulled out from under the sink, and the workability during cleaning is considered to be better than that of the interceptor disclosed in Patent Document 1. However, even in the interceptor described in Patent Document 2, there is still room for further improvement in terms of the ease of cleaning / maintenance work and the durability of the connecting pipe and its joint as described below.

  First, although the interceptor is movable, its travel stroke must be relatively small, and the interceptor cannot be pulled out from under the sink.

  This is because in order to increase the movement stroke of the interceptor, it is necessary to provide a sufficient margin in the length of the flexible pipes (first connection pipe 27, second connection pipe 28) connected to the interceptor. However, in the interceptor of Patent Document 2, it is possible to make the length of the flexible pipe (second connection pipe 28) connecting the interceptor (grease interceptor 10) and the floor opening 72a relatively long. Although there is a flexible pipe (first connecting pipe 27) that connects the discharge port 41 of the sink 40 and the grease interceptor 10, the space between the bottom of the sink and the top of the interceptor is generally not wide (this In order to increase the space, the height of the interceptor must be kept low, and the processing capacity of the interceptor will be reduced, and the depth of the inside of the interceptor will become shallow, resulting in reduced interception performance. It is difficult to make this long. For this reason, the interceptor can be pulled out only for the margin length of the second connection pipe 28, and for example, it is not possible to perform the cleaning work by completely pulling out the interceptor from under the sink.

  Further, when the first connecting pipe 27 is lengthened, the drop of the first connecting pipe 27 (the height difference between the discharge port 41 and the water receiving port 14) is the second connecting pipe 28 (the drain port 22 and the floor opening 72a). Therefore, when the interceptor is in normal use, the first connecting pipe 27 is bent, and the drainage is stagnated in the middle of the pipe. .

  Further, the shorter the connecting pipe, the more the moving inertia force (the moment to pull out the interceptor) when pulling out the interceptor is the connecting pipe and its joint (joint with the first connecting pipe 27, the sink drain port and the water receiving port). It is easy to get on, and it is easy to cause the deterioration. In particular, this type of interceptor, even if it is a relatively small type, can move its contents, including the accumulated oil and fat and drainage, from tens to hundreds of kilograms. If the inertial force is frequently applied each time cleaning is performed, the load applied to the connecting pipe and the joint cannot be considered light.

  Furthermore, there is no trap between the interceptor and the sink outlet to block the reverse flow of odors (as mentioned above, the gap between the sink lower surface and the upper surface of the interceptor cannot be made large. It is difficult to provide), and there is also a difficulty that odors rise directly to the sink through the connecting pipe (first connecting pipe 27) from the wastewater stored in the interceptor and the accumulated fats and oils.

  This problem is not limited to the interceptor that removes fats and oils contained in kitchen wastewater, but also applies to wastewater treatment equipment that targets wastewater discharged from various facility sinks and containing various other contaminants. There is a desire for a solution.

  Accordingly, an object of the present invention is to obtain a more convenient drainage system that is excellent in ease of cleaning and maintenance work and durability.

  In order to achieve the above object and solve the problem, a drainage system according to the present invention is provided with a moving means and is disposed so as to be movable on a floor surface lower than the sink drainage port of the sink, and is introduced from the introduction port. A separator that separates the contaminants by a blocking means and discharges treated water from the discharge port, an instrument drain pipe that guides the waste water discharged from the tank drain port to the introduction port, and at least partly flexible A drainage system comprising a transfer pipe for transferring treated water from the discharge port to a floor drain port, wherein the interceptor includes the introduction port on a ceiling surface, and one end is connected to the tank drain port. The other end opening of the appliance drain pipe is disposed above the introduction port.

  In the drainage system of the present invention, the sink tank outlet and the interceptor are not connected by piping or the like, and the drainage from the sink tank has passed through the appliance drain pipe having one end connected to the tank drain. After that, it is discharged from the other end of the instrument drain pipe, falls, and is received by the introduction port provided in the interceptor. This introduction port opens at a position below the other end opening of the instrument drain pipe so that it can receive drainage discharged from the other end of the instrument drain pipe and introduce it into the interceptor. The other end opening of the instrument drain pipe connected to the sink and the inlet of the interceptor are arranged so as to face each other with a certain interval so that the interceptor can be moved when not in use. .

  As described above, in the drainage system of the present invention, since the sink and the interceptor are not connected to each other, there is no situation in which the connecting pipe and the joint portion to which these are connected conventionally are loaded and deteriorated. . Moreover, the drawing-out stroke of the interceptor can be made longer, and the workability during cleaning and maintenance can be improved.

  The interceptor is provided with a intercepting means for removing contaminants contained in the wastewater received from the introduction port, and after the contaminants are removed from the wastewater introduced into the interceptor from the introduction port, It is discharged as treated water from the discharge port and sent to the floor drain through a transfer pipe.

  The intercepting means is not particularly limited as long as it can remove impurities contained in the sink drainage. In a typical example, the contaminants are fats and oils, and the intercepting means can remove the fats and oils by separating them from the water by using the specific gravity difference between the water and the fats. Objects are not necessarily limited to fats and oils, and include, for example, plaster (gypsum), sand, mud, earth, paint, oil paints, other water-insoluble substances, etc., and may have a specific gravity smaller or larger than water. . For contaminants with a specific gravity greater than water, for example, if the contaminants are submerged in the drainage inside the interceptor and the supernatant is discharged from the outlet, the contaminants can be removed from the drainage. I can do it.

  Further, as an example of the intercepting means, it is possible to adopt the same structure as the interceptor described in Patent Documents 1 and 2. Specifically, by providing a partition inside the interceptor and partitioning, at least three rooms of the introduction chamber, the interception chamber, and the drainage chamber arranged in order on the flow path of drainage from the introduction port to the discharge port are provided. Form. In addition, the drainage is circulated between the introduction chamber and the interception chamber, and between the interception chamber and the drainage chamber via the bottom surface of the interceptor (the bottom portion of the stored drainage), while the water surface is included. Oils and fats float on the water surface of the interception chamber, which is partitioned by a bulkhead at the top of the chamber, and above the water surface of this interception chamber (between the bulkhead that partitions the introduction chamber and the interception chamber, and the bulkhead that partitions the interception chamber and the drainage chamber) Capturing oils and fats.

  The interceptor is placed on the floor so as to be movable via the moving means, and can be installed in the lower space of the sink. Further, in order to enable the moving operation by the moving means, at least a part of the transfer pipe connecting the discharge port of the interceptor and the floor drain port is flexible.

  The moving means can typically be constituted by wheels (for example, casters). Further, as the moving means, a guide rail extending in the moving direction of the interceptor may be provided on the leg portion of the sink, and a rail engaging portion that engages with the guide rail may be installed in the interceptor. With such a guide mechanism, when the interceptor is pulled out from under the sink and then placed under the sink, the interceptor is placed in the initial position (the inlet of the interceptor is directly below the other end opening of the instrument drain pipe). The position can be easily and reliably returned to the position just positioned at the position.

  The introduction port is preferably formed in the ceiling surface of the interceptor and has a larger opening area than the other end opening of the appliance drain pipe. This is because the drainage discharged downward from the other end opening of the instrument drain pipe is more reliably received and introduced into the interceptor.

  The inlet preferably includes an odor reducing lid, which covers most of the opening portion of the inlet and has flexibility while the drainage from the appliance drain pipe falls. It shall have a blocking member that bends downward with the weight of the drainage and allows the drainage to flow into the interceptor. Thereby, it is also possible to greatly relieve the odor from being released from the interceptor through the inlet.

  Furthermore, a strainer capable of capturing solid waste contained in the waste water may be provided at the introduction port portion (for example, a lower position of the introduction port).

  Further, at least a part of the appliance drain pipe is vertically extendable at a position above the introduction port, whereby the height of the other end opening of the appliance drain pipe facing the introduction port may be changed. If such an instrument drain pipe is provided, it is possible to flexibly cope with various sinks having different heights of sink drain ports.

  In addition, the present invention can be applied not only to a sink having a single tank, but also to a sink (or a plurality of sinks) having a plurality of tanks. In order to guide the drainage from one tank to the inlet of one interceptor, a plurality of horizontal drainage pipes with one end connected to the tank drainage of one tank, and the other ends of the plurality of horizontal drainage pipes Is connected to collect drainage from each tank, and has a junction pipe portion having an opening arranged to face the introduction port to guide the drainage to the interceptor. It is desirable that a partition wall for preventing intrusion of drainage from one of the horizontal drainage pipes to the other of the horizontal drainage pipes is provided inside.

  When collecting wastewater from multiple tanks and treating them with interceptors, simply connect one end of each horizontal drainage pipe to the tank drain of each tank using multiple horizontal drainage pipes. The drainage pipes may be joined together by a normal joining drainage joint and opened toward the inlet of the interceptor, but there are many cases in which the amount of stored water or the amount of drainage varies depending on the sink. For this reason, if the horizontal drainage pipe parts connected to a plurality of tanks are simply joined and connected to each other by a normal joining drainage joint, the drainage from one tank flows backward through the horizontal drainage pipe parts connected to other tanks. Things can happen. On the other hand, if the partition wall is provided as described above, it is possible to prevent such a backflow and smoothly drain the wastewater from all the tanks to the interceptor for processing.

  According to the drainage system of the present invention, the convenience and durability of cleaning / maintenance work can be improved and the convenience can be further improved.

  Other objects, features, and advantages of the present invention will become apparent from the following description of embodiments of the present invention described with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

〔overall structure〕
1 to 8 show a drainage system according to an embodiment of the present invention. As shown in these drawings, the drainage system is configured to remove oils and fats from the drainage discharged from the sink 1 and then discharge the fats and oils to the floor drain port 4. Instrument drain pipe 31, guide mechanism 21 for guiding the interceptor 11 in and out of the lower space of the sink 1 (tanks 1a, 2a), and drainage (contaminant) after treatment by the interceptor 11 And a transfer pipe 41 for guiding the treated water from which the oils and fats are removed) to the floor drain port 4.

  Further, the sink 1 to which the drainage system of the present embodiment is applied is not limited to the illustrated example, but is supported at a certain height from the floor surface 5 by a plurality of (for example, four) sink legs 3. For example, two tanks 1a and 2a are provided, and tank drains 1b and 2b for discharging water in the tanks 1a and 2a are respectively provided on the bottom surfaces of the tanks 1a and 2a. The number of sink tanks may be one, or three or more.

[Interceptor]
The interceptor 11 has an overall shape of a substantially rectangular parallelepiped having an inner space surrounded by a top plate (ceiling surface) 11e, side plates (front plate 11a, back plate 11b, left side plate 11c and right side plate 11d) and bottom plate 11f. And is accommodated in the lower space of the sink 1 (the tanks 1a and 2a). The top plate 11e of the interceptor 11 is provided with an introduction port 12 for receiving the drainage from the sink 1, and this introduction port 12 is connected to the other end opening 36 (afterwards) of the appliance drainage pipe 31 connected to the tank drainage ports 1b and 2b. It is opened upward at a position directly below. In addition, in order to prevent the odor from being released from the inside of the interceptor 11 through the introduction port 12, the introduction port 12 receives the waste water flowing down from the other end opening 36 of the appliance drain pipe 31 into the interceptor 11. A chrysanthemum split lid 19 (odor reduction lid) is provided.

  On the other hand, the right side plate 11 d of the interceptor 11 is provided with a discharge port 13 through which drainage in the interceptor 11 flows out of the interceptor 11. Then, by dividing the inside of the interceptor 11 by a plurality of partition walls (partition plates) 55, the introduction chamber 51, the interception chamber 52, and the drainage chamber are sequentially arranged along the flow path of drainage from the introduction port 12 to the discharge port 13. 53 is formed.

  The internal structure of the interceptor 11 and the principle of capturing oils and fats are not limited to specific ones. For example, the same structure as that of the conventional interceptor can be adopted, but a brief description will be given with reference to FIG. To do. As shown in FIG. 6, a plurality of partition walls 55 are provided inside the interceptor 11 to partition the inside of the interceptor 11, thereby sequentially introducing the introduction chamber 51 and the interception chamber 52 between the introduction port 12 and the discharge port 13. And the drainage chamber 53 is formed. The partition wall 55 partitioning each of the chambers 51 to 53 stands up above the drainage water level (drainage surface) 91 in the interceptor 11, while the lower end is spaced upward from the upper surface of the interceptor bottom plate 11f. Adjacent chambers communicate with each other, allowing drainage to pass through.

  Further, on the downstream side of the partition wall 55 forming these chambers 51 to 53, a barrier plate that rises upward from the upper surface of the interceptor bottom plate 11f and has a height that is substantially the same as or slightly larger than the height of the lower end of the partition wall 55. 56 is provided. The barrier plate 56 prevents the drainage from flowing from the introduction chamber 51 to the drainage chamber 53 along the interceptor bottom plate 11f in a short-circuit manner, and prevents the drainage flow that has passed through the lower gap of the partition wall 55 from the interception chamber 52 (and drainage). By raising in the chamber 53), the function of promoting the floating of the fats and oils 92 to the drainage surface 91 is achieved.

  In this embodiment, the partition wall 55 is also provided at an intermediate position of the interception chamber 52. However, in the present invention, even if this is omitted or an appropriate number of partition walls 55 and barrier plates 56 are added. I do not care.

  The drainage received in the introduction chamber 51 through the introduction port 12 passes through the lower gap of the first partition wall 55 and enters the blocking chamber 52. The waste water that has flowed into the interception chamber 52 flows so as to meander up and down in the interception chamber 52, while oils and fats 92 having a specific gravity lighter than that of the water float on the drainage surface, and a partition wall that defines the interception chamber 52. Captured between 55 and 55. On the other hand, the drainage from which the fats and oils 92 have been removed passes through the lower gap of the partition wall 55 downstream of the blocking chamber and flows into the drainage chamber 53. Then, the wastewater that has entered the drainage chamber 53 passes through the side plate of the interceptor and is discharged from the discharge port 13 to the outside of the interceptor 11 through the extraction pipe 18 inserted into the drainage chamber 53.

  4 and 5 show the internal structure of the interceptor 11 provided in the present embodiment. In the present embodiment, the introduction is performed inside the housing of the interceptor 11 based on the principle shown in FIG. A chamber 51, a blocking chamber 52, and a drain chamber 53 are formed.

  Specifically, the introduction chamber 51 is formed immediately below the introduction port 12 so that the waste water flowing from the introduction port 12 can be received first. The introduction chamber 51 is provided with a basket-shaped strainer 61, and the waste water flowing from the introduction port 12 first passes through the strainer 61. The strainer 61 is provided with a large number of small holes, captures dust and leftovers that have flowed into the interceptor 11 together with the drainage, and allows only the drainage to pass through. The strainer 61 can open the top plate 11e of the interceptor 11 and take it out, whereby the dust or the like captured in the strainer 61 can be discarded.

  A blocking chamber 52 is formed in the back of the introduction chamber 51, and a drainage chamber 53 is provided in front of the blocking chamber 52 and next to the introduction chamber 51. The partition walls 55 are provided between the introduction chamber 51 and the blocking chamber 52 and between the blocking chamber 52 and the drainage chamber 53, respectively. Further, the weir plates 56 are provided downstream of the partition walls 55, respectively. Further, a partition plate 57 is provided between the introduction chamber 51 and the drainage chamber 53 to block the drainage flow. The take-out pipe 18 for discharging the drainage from the interceptor 11 is inserted into the drainage chamber 53 so that one end is positioned near the bottom of the drainage chamber 53 and the discharge port 13 is provided at the other end. As a result, it becomes possible to prevent the fats and oils 92 floating on the drainage surface in the drainage chamber 53 from flowing out of the interceptor 11 from the discharge port 13, and a trap structure is formed by the take-out pipe 18. It is also possible to prevent harmful sewage gas and pests rising from the sewage to the drain pipe from entering the interceptor 11 through the floor drain port 4 through the transfer pipe 41. The drainage in the interceptor 11 is discharged from the discharge port 13 by overflow through the extraction pipe 18 and flows into the transfer pipe 41 connected to the discharge port 13.

  A drain valve 14 is provided at the lower portion of the side wall of the drainage chamber 53 so that drainage in the interceptor 11 can be drained during cleaning or maintenance. A caster (wheel) 16 is provided on the bottom surface of the interceptor 11, and the interceptor 11 is movably supported on the floor surface 5 by the caster 16. Further, a handle 15 is attached to the front plate 11 a of the interceptor 11, and the interceptor 11 can be pulled out from under the sink 1 with the handle 15. The caster 16 is provided with a stopper for stopping the rotation of the wheel. When the caster 16 is installed under the sink 1, the wheel 11 is stopped with this stopper to inadvertently pull out the interceptor 11 and drain the water from the sink 1. It is possible to prevent an accident that the spilled from the inlet 12 leaks to the surroundings.

[Equipment drain pipe]
The instrument drain pipe 31 joins the horizontal drain pipe part 32 which conveys the waste water from each tank (1a, 2a) of the sink 1 and the waste water conveyed through the plurality of horizontal drain pipe parts 32 into one, 11 and a joining pipe portion 33 that flows down toward the inlet 12. The horizontal drain pipe portions 32 are provided in the number corresponding to the number of tanks of the sink 1 (two in this example). Each horizontal drain pipe portion 32 has one end connected to the tank drain ports 1b and 2b and the other end. Are connected to the merging pipe section 33 and the drainage from the sink tanks 1a and 2a is merged in the merging pipe section 33. Note that the number of tanks of the sink 1 may be any number (for example, one tank sink, three tank sinks, four tanks or more sinks may be used). In this case, the number of horizontal drain pipe portions 32 according to the number of tanks. Should be provided. In the case of a single tank sink, the merging pipe portion 33 as in the present embodiment is not necessary, and from the tank drain port 1b to the upper portion of the inlet port 12 by a simple pipe having no partition wall 35 (described later). You can guide the drainage.

  As shown in detail in FIGS. 7 and 8, the merging pipe portion 33 is erected so as to extend substantially vertically above the inlet 12 of the interceptor 11, the upper end is closed, and the side surface (circumferential surface). For example, two horizontal drainage pipe portions 32 are connected to each other. The two horizontal drainage pipe parts 32 are connected to the merging pipe part 33 so as to meet each other across the merging pipe part 33 (so as to face each other / at an angle of 180 ° to each other). Inside, a partition wall 35 is provided so as to separate the connecting portions of the opposed horizontal drain pipe portions 32. The partition wall 35 extends in a substantially vertical direction over substantially the entire length of the merging pipe portion 33, divides the inside of the merging pipe portion 33 into two in the vertical direction, and one of the horizontal drainage pipe portions 32 is connected to the horizontal wall. The first water receiving portion 37a that receives drainage from the drainage pipe portion 32 and the second water receiving portion 37b that is connected to the other horizontal drainage pipe portion 32 and receives drainage from the horizontal drainage pipe portion 32 merge. It is formed in the tube part 33.

  When the appliance drain pipe 31 is provided with three or more horizontal drain pipe sections 32 (when the sink 1 has three or more tanks), each horizontal drain pipe section 32 is similarly connected to the horizontal drain pipe section 32. What is necessary is just to provide the partition wall which forms the several (3 or more) water receiving part which receives the waste_water | drain from the drain pipe part 32 in the inside of the junction pipe part 33. FIG.

  Thus, if the partition wall 35 is provided in the junction pipe part 33, even if the amount of drainage / water pressure differs between both tanks 1a and 2a (both side drainage pipe parts 32 and 32), the amount of drainage (water pressure) is increased. It is possible to prevent the situation where the drainage of the tank on the smaller side is hindered or the drainage of the drainage from one side drainage pipe part 32 to the other side drainage pipe part 32 occurs. Even when it is provided, drainage can be performed smoothly from all tanks.

  The lower end of the merging pipe portion 33 is opened so that the drainage water flowing in from the respective horizontal drainage pipe portions 32 can flow downward. The opened lower end opening (the other end opening of the instrument drain pipe 31) 36 is arranged so as to face the introduction port 12 of the interceptor 11 in the vertical direction with a certain distance. In particular, as shown in FIG. 7, the opening area (diameter) of the introduction port 12 is made larger than the opening area (diameter) of the merging pipe portion 33, whereby the drainage discharged from the lower end opening 36 of the merging pipe portion 33. Can flow into the inlet 12 reliably.

  In the present invention, the planar shape of the inlet 12 and the lower end opening 36 of the merging pipe portion 33 is not limited to a circle, but may be other shapes. In order to reliably receive the drainage falling from the inlet 12 at the inlet 12, the lower end opening of the merging pipe portion 33 is completely included in the inlet 12 when viewed from a plane (so as to be in the inner region of the inlet 12). Both opening areas and positional relationships are set.

  The lower end opening (the other end opening of the instrument drain pipe 31) 36 of the junction pipe portion 33 may be configured such that its height position can be changed. This is in order to be able to flexibly cope with sinks (tanks) with various heights. A mechanism that can change the height of the lower end opening is not particularly limited. For example, as shown in FIG. 9, a bellows tube 38 that can be expanded and contracted in the vertical direction is provided at the lower end portion of the merging tube portion 33 so that the height position of the lower end opening 36 can be changed. As shown in the drawing, a nut pipe 39 having a reverse screw is inserted in the middle of the merging pipe section 33 (33a, 33b) and the nut pipe 39 is rotated to move the tip end section 33b of the merging pipe section 33 up and down. It doesn't matter if you do. Further, the same effect can be obtained even if a structure that enables expansion and contraction by the bellows pipe 38 and the nut pipe 39 is provided in the vertical direction portion of the horizontal drainage pipe portion 32 and the height position of the lower end opening 36 can be changed.

  Furthermore, instead of expanding and contracting the tube in this way, it is possible to adopt a method such as attaching an extension tube to the tip of the merging tube portion 33. Conversely, by forming the peripheral wall of the inlet 12 so as to be expandable and contractible upward (for example, a bellows, a screw, a nested structure, etc.), the same object can be achieved even if the height on the inlet 12 side can be changed. I can do it.

[Transfer pipe]
The transfer pipe 41 connecting the discharge port 13 for taking out the waste water from the interceptor 11 and the floor drain port 4 is flexible so that the interceptor 11 can be moved. It is not always necessary to provide flexibility. In the present embodiment, a flexible tube 42 having flexibility is used for a part of the transfer tube 41 (a portion on the side of the interceptor 11), and other than that portion is a straight tube and a joint having no normal flexibility. The constructed piping 43 is used. Further, the floor drain port 4 to which the transfer pipe 41 is connected is not necessarily limited to that installed on the floor surface, and may be provided on, for example, a wall surface. In short, any drainage outlet for discharging the drainage of the sink 1 to the outside of the facility may be used.

〔transportation〕
The side surface of the interceptor 11 (the outer surface 11c of the left side plate) is provided with a rail engaging portion 22 having an L-shaped cross section extending in the front-rear direction (the withdrawal direction of the interceptor 11). Similarly, the cross section extends in the front-rear direction (the direction in which the interceptor 11 is pulled out) and receives the vertical portion (rising portion) of the rail engaging portion 22 and engages with the rail engaging portion 22 so as to be relatively slidable. A U-shaped guide rail 23 is provided.

  The guide mechanism 21 composed of the rail engaging portion 22 and the guide rail 23 constitutes a moving means in combination with casters (wheels) 16 and allows movement of the interceptor 11 in the front-rear direction, while in the left-right direction (sink 1, the movement of the interceptor 11 in the width direction of 1) is regulated, whereby the interceptor 11 can be pulled out straight from the bottom of the sink and the pulled-out interceptor 11 is returned to the original position under the sink ( It is possible to easily return the inlet 12 to the initial position facing the other end opening 36 of the appliance drain pipe 31.

  In addition to this example, the moving means comprising the guide mechanism 21 and the casters (wheels) 16 can change the shape of the guide member on the interceptor side or the sink side, for example. Various mechanisms and structures can be adopted, such as providing a wheel on the other side to guide the interceptor. In the embodiment of the present invention, a stopper is provided on the caster (wheel) 16 as a measure for preventing the interceptor 11 from being inadvertently pulled out. However, the present invention is not limited to this. For example, at the initial position of the interceptor 11, a communication hole is provided in the rail engaging portion 22 and the guide rail 23 so as to communicate with the pin, and a pin is inserted into the communication hole in a normal state to prevent the movement of the interceptor 11. The pin may be removed when the interceptor 11 is cleaned so as to be movable.
