TECHNICAL FIELD
[0001] The utility model belongs to floor drain technical field, concretely relates to a large flow movable core floor drain. BACKGROUND
[0002] Floor drain is an important interface connecting drainage pipe system and indoor floor, and domestic floor drain is mainly applied to bathroom, balcony and other environment. The floor drain of prior art usually comprises cover plate, filter screen and box body, the box body is provided with a downcomer hole for inserting floor drain core in the center, the floor drain core is inserted into the downcomer pipe, water flows through the cover plate, filter screen and box body, and is discharged into the downcomer pipe through the floor drain core, the downcomer hole is fixed relative to the box body, and the drain outlet cannot be moved in any direction and size within a certain range of the floor drain box body, so that even if the distance between the downcomer pipe and the wall is within the size range in the floor drain, it is still difficult to accurately install the floor drain edge close to the wall, and the floor drain edge is usually away from the wall.
[0003] Users have higher and higher requirements on the practicability and aesthetics of residence, and hope that the floor drain edge can be accurately set close to the wall. The purpose of doing so has four advantages: 1. It is easier to create a drainage slope. After the floor drain edge is accurately set close to the wall, the floor tiles or other ground materials do not need to be sloped to the floor drain as usual, but only need to be sloped to the floor drain on both sides or one side to smoothly drain water, so that the bathroom floor is not easy to accumulate water. 2. It is more beautiful and meets the requirements of modern home aesthetics. The floor drain close to the wall does not need to be sloped on all sides, so it does not need to be obliquely cut to the flat hard tiles, and there is no depression around the floor drain that is not close to the wall. 3. It is not easy to step on the water in the floor drain and the low part of the floor drain. Especially in the shower area, if the floor drain is not close to the wall near the shower stand, the user may cause poor drainage due to hair blocking part of the drain outlet when showering, and the floor drain is the lowest part of the floor, so the depth of the water stepped on by the feet exceeds other positions, and even the floor drain is pressed under the feet to cause water accumulation. If the floor drain is installed close to the wall, the user's feet are usually not close to the wall when showering, so it is not easy to step on the water in the floor drain and the low part of the floor drain. 4. It is convenient for tile paving construction, and reduces the situation that the slope is wrong during paving, causing poor drainage. After the floor drain is close to the wall, the drainage slope can drain water to the bottom end of the wall, and does not need to be obliquely cut, so it is easier to construct.
[0004] In the existing real estate construction, the position of the sewer pipe laid after the development company builds the bathroom is considered for the possibility of later wall tile laying, and the sewer pipe ensures the installation redundancy, and the position of the sewer pipe is not accurately set according to the existing conventional size floor drain, but is in the approximate position required. When the sewer pipe is installed, the water worker also cannot accurately calculate the center of the sewer pipe according to the center of the floor drain, because the conventional floor drain core is fixed on the floor drain, and when the sewer pipe is installed, that is, the floor drain core of the floor drain can only be inserted into the sewer pipe, and the floor drain main body box body also only moves the corresponding size. For example, the diameter of the current mainstream sewer pipe of the residence is 50mm, the inner diameter is about 46mm, and the conventional floor drain core has a mainstream aperture of about 41mm, so that the single side movable distance of the floor drain core after being inserted into the sewer pipe is only about 2.5mm. If the sewer pipe is changed to a large aperture, more costs will be increased, and the change will also increase the risk of later sewer pipe leakage, and part of the ground cannot increase the sewer pipe due to the height reason. When the floor drain sewer pipe is changed, the wall tile laying work has not been carried out, and the wall body verticality deviation and the tile laying material are different, and the tile laying thickness (such as the cement sand or the tile glue wall tile thickness is different) is different, and the tile laying thickness of different tile workers is different. At least three factors affect the wall tile thickness, so the final thickness and the estimated deviation are usually 1-30mm, so the movable distance of the floor drain core in the 50 pipe is less than the wall tile thickness deviation distance, and the floor drain cannot meet the requirement of accurate wall laying.
[0005] There is another case that the development company reserves or renovates the sewer pipe center to be too close to the wall, and the existing size floor drain cannot be installed. Therefore, in the two cases, people urgently need a floor drain with a sewer core that can move in a certain range in any direction and any size, so that even if the pipe is not changed or the position of the sewer pipe is not accurate, the floor drain edge can be accurately laid on the wall. The utility model discloses a large-flow movable core floor drain
[0006] Therefore, the embodiment of the utility model provides a large-flow movable core floor drain, which can realize the purpose of laying the floor drain on the wall and smoothly draining even if the position of the sewer is not suitable.

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0030] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.
[0031] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0032] In addition, the terms "first", "second", etc. are only used for differentiation in description, and cannot be understood as indicating or implying relative importance. In the present application, "inner" refers to the direction close to the center of the floor drain; "outer" in the present application refers to the direction away from the center of the floor drain; "bottom" in the present application refers to the direction close to the ground; "top" in the present application refers to the direction away from the ground.
[0033] Please refer to Figures 1-3The embodiment of the utility model provides a large -flow movable core floor drain, the whole presents as square shape. According to need, it can also be set as rectangle and so on shape, and the application is preferably square. Including cover plate 1, filter screen 4, tablet 5, fastening screw 7, wedge piece 8, with core bottom plate 9, sealing ring 11 and box body 17, the centre of tablet 5 is provided with limiting hole 6.
[0034] Cover plate 1 presents as square, and the four outer side walls of cover plate 1 are each provided with stand 3. Stand 3 and cover plate 1 are fixedly connected, and the two can be integrally formed, or other ways (such as bonding, welding etc.) are used to make the two fixed together. Stand 3 extends outward and downward from the outer side wall of cover plate 1, that is, the inner side wall of stand 3 is close to the outer side wall of cover plate 1, and the bottom surface of stand 3 protrudes the bottom surface of cover plate 1. The outer dimension of cover plate 1 with stand 3 is slightly smaller than the inner dimension of box body 17, so that cover plate 1 with stand 3 can be placed into box body 17. And based on the existence of stand 3, water inlet groove 2 is formed between cover plate 1 and box body 17, and water flow can enter floor drain from water inlet groove 2, and further flow to filter screen 4 from the gap between the inner side wall of box body 17 and cover plate 1, and is discharged into the sewer.
[0035] In the embodiment, cover plate 1 is set as a whole, without gap or aperture, and water flow can only flow from water inlet groove 2; The whole of cover plate 1 can be an integrally formed metal plate, plastic plate etc., or can be a frame or a shallow box and inlaid tiles, which is beautiful and elegant; According to need, cover plate 1 can also be set as a mesh, fence etc., and water flow can not only flow from water inlet groove 2, but also flow into the sewer through the gap or aperture on cover plate.
[0036] The box body 17 is a thin square box structure, integrally formed, without top surface, bottom surface only one circle and a large area opening. Specifically, the box body 17 includes the side frame 12, the screw hole 14 and the bottom circle 15, and the large area opening in the bottom circle 15 forms the window 16. The area of the window 16 accounts for more than 70% of the bottom surface area of the box body 17. The side frame 12 includes the first layer and the second layer integrally formed, and the first layer and the second layer are staggered, and the staggered plane on the inner wall of the side frame 12 forms the layer table 13, which is specifically a frame-shaped plane distributed inward along the vertical direction of the side frame 12. The layer table 13 can be used to support the stand 3 outside the four sides of the cover plate 1. Since the core bottom plate 9 is arranged in the box body 17, and the drain core 10 needs to be inserted into the drain pipe through the window 16; therefore, the size of the window 16 should be as large as possible, that is, the width of the bottom circle 15 should be as small as possible, so that the drain core 10 has a wider distribution space and is more flexible to use. For example, when the box body 17 is sleeved outside the drain pipe and one side or both sides of the box body 17 is attached to the wall, the drain pipe is located in the window 16 on the bottom surface of the box body 17, at this time, the core bottom plate 9 is cut into a suitable shape so that the drain core 10 is just inserted into the drain pipe, and the floor drain is designed to be movable in any direction and size within the window 16, and can be used attached to the wall.
[0037] When the cover plate 1 with the stand 3 is placed into the box body 17, the stand 3 is just supported by the layer table 13, that is, the bottom surface of the stand 3 abuts against the layer table 13; at the same time, the top surface of the cover plate 1 keeps the same height with the top of the box body 17, which is beautiful and elegant; at the same time, due to the existence of the stand 3 fixedly connected with the cover plate 1, the water inlet groove 2 is formed between the four outer sides of the cover plate 1 and the inner sides of the side frame 12 of the box body 17, at the same time, the stand 3 is supported by the layer table 13, the bottom surface of the cover plate 1 does not contact the filter screen 4, and the water flow can smoothly flow onto the filter screen 4 through the water inlet groove 2, and then enter the drain pipe through the core bottom plate 9.
[0038] Screw holes 14 are arranged on the four inner side walls of the side frame 12 of the box body 17, and each inner side wall has one screw hole. The screw hole 14 is specifically located below the layer table 13 and at the middle position in the horizontal direction of each inner side wall. The screw hole 14 is a blind hole. The purpose of arranging the screw hole 14 is to use the fastening screw 7 to detachably connect the related parts of the floor drain through the pressing piece 5 and the wedge-shaped piece 8, and the connection mode will be further described below.
[0039] The pressing piece 5 is a square, and a limiting hole 6 is arranged at the center position thereof. The limiting hole 6 is specifically a through hole, and the through hole includes two sections with different hole diameters. The first section has a smaller hole diameter, which can pass through the screw rod of the fastening screw 7 but cannot pass through the screw head thereof. The second section has a larger hole diameter, which can accommodate the screw head of the fastening screw 7. The design of the two-section type with different hole diameters can realize the effect that the fastening screw 7 is limited and the screw head thereof is inserted into the pressing piece 5 without external leakage.
[0040] The filter screen 4 is provided with a plurality of through holes or gaps to achieve smooth water flow and prevent hair, solid waste and the like from passing through the filter screen into the drain pipe. The filter screen 4 has a square overall shape, and after being placed in the box body, it abuts against the pressing piece 5, that is, the bottom surface of the filter screen 4 can be in contact with the top surface of the pressing piece 5. This design allows the filter screen 4 to be placed in the box body 17 without being interfered by the pressing piece 5 and / or the fastening screw 7, and is convenient to take out and place at any time. The filter screen 4 and the core bottom plate 9 are separated by the pressing piece 5. Since the pressing piece 5 has a certain thickness, a gap is formed between the filter screen 4 and the core bottom plate 9. The water flow can not only flow directly into the drain core 10 through the hole directly above the drain core 10 and then enter the drain pipe, but also flow into the core bottom plate 9 through the holes of other positions of the filter screen 4, and then flow smoothly in the gap and enter the drain core 10, and then enter the drain pipe through the drain core 10. Even if some of the through holes or gaps of the filter screen 4 are blocked by hair, solid debris and the like, the through holes or gaps at other positions can still pass through the water flow, reducing the unnecessary cleaning frequency of the filter screen 4.
[0041] The core bottom plate 9 has a square overall shape, and includes a planar cuttable panel and the drain core 10. The drain core 10 is located at the center of the panel and is integrally formed with the panel. The size of the core bottom plate 9 is greater than that of the box body 17, and the length of the side is preferably 1.5 times the length of the side of the box body. If necessary, it can also be set to a higher multiple. The purpose of this design is to consider extreme cutting conditions while ensuring redundancy. When the drain core 10 needs to be located at the edge or corner of the window 16, the drain core 10 is within the range of the other pair of edges of the window 16, and is a cuttable panel. The length of the side of the core bottom plate 9 is 1.5 times or more the length of the side of the box body 17, which can ensure that no matter where the drain core 10 needs to be located in the window 16, the cut core bottom plate 9 can be placed in the box body 17, and the panel size is sufficient and can be effectively fixed. Such size can achieve the purpose of moving the panel of the core bottom plate 9 in any direction and size within the window range of the drain core 10 after cutting. In order to facilitate cutting, the core bottom plate 9 is made of materials that are easy to process, such as PVC, PE, ABS, PTFE, PPR and other plastics, and aluminum alloy and other materials with appropriate hardness and easy to cut. The shape and structure of the drain core 10 can refer to the existing design, and different diameters can be set according to different inner diameters of the drain pipe. When in use, it is inserted into the drain pipe.
[0042] The drain core 10 is directly opened at the center of the core bottom plate 9 and is integrally formed with the panel. When in use, it can be directly inserted into the drain pipe, so the outer diameter of the drain core 10 is slightly smaller than the inner diameter of the conventional drain pipe.
[0043] In contrast, the existing floor drain design, the drain core is not designed as an integral part of other components, often independent, need to hang or card in the box body bottom opening position, that is, the existing floor drain in the box body fixed position is provided with an opening, in order to fix the box body and avoid water flow through the opening into the drain pipe outside the position, the opening extends a small section of cylindrical structure and needs to be inserted into the drain pipe; and the drain core needs to be carded or hung in the opening of the box body. It can be seen that the outer diameter of the cylindrical structure under the opening of the box body is equal to or slightly smaller than the inner diameter of the drain pipe, and the outer diameter of the drain core is equal to or slightly smaller than the inner diameter of the cylindrical structure.
[0044] It can be seen that the inner diameter of the drain core in the prior art is smaller than the inner diameter of the floor drain provided in the present application; the smaller the inner diameter, the smaller the water flow. Therefore, the floor drain provided in the present application has a larger drainage capacity. According to the applicant's verification, when the drain pipe is 50, the inlet cross-sectional area of the drain core provided in the present application is 1320 square millimeters, and the inlet cross-sectional area of the drain core of the existing ordinary floor drain is within 1018 square millimeters. If both the drain cores use the same gravity cover plate deodorizing drain core, due to the need for the drain core component to occupy a position, the flow-through port or the drainage port of the drain core is only half of the inlet port. Then the effective discharge water cross-sectional area of the floor drain provided in the present application is 660 square millimeters, and that of the existing floor drain is 509 square millimeters, and the drainage capacity is increased by about 29.6%. The floor drain provided in the present application has two advantages compared with the prior art, 1 is if there are hairs and other foreign matters blocking part of the drain core, the drain core of the floor drain provided in the present application is relatively not easy to block; 2 is part of the actual water pressure of the residence exceeds 0.35 megapascal, when the water pipe bursts, the water flow will exceed 20L / min, if the floor drain is used for washing machine drainage and ground drainage, at this time the drainage demand is 32L / min, under the same floor drain core condition, the drainage capacity of the existing floor drain is only about 25L / min, and the drainage is not enough, resulting in flooding; and if the actual drainage capacity is within the drainage capacity of the floor drain provided in the present application, the water can be successfully drained and flooding can be avoided.
[0045] Please refer to Figures 4-6The bottom ring 15 has a certain thickness and is integrally formed with the side frame 12, and has a square frame shape. When viewed from the top surface of the box body 17, the outer edge length of the bottom ring 15 is the maximum edge length of the bottom of the box body, and the inner edge length is the edge length of the window 16. The cut strip bottom plate 9 is placed in the box body 17, and the lower water core 10 is inserted into the sewer. The sealing ring 11 is arranged between the strip bottom plate 9 and the bottom ring 15 of the box body 17. The sealing ring 11 is also square, and the outer edge length is equal to the outer edge length of the top surface of the bottom ring 15, and the inner edge length is equal to the edge length of the window 16. That is, the width of the sealing ring 11 is equal to the width of the top surface of the bottom ring 15, so that the sealing ring 11 is distributed along the outer circle of the window 16, and has the same shape and size as the top surface of the bottom ring. The sealing ring 11 is made of soft sealing materials such as rubber and silica gel, which can prevent water from flowing through the gap between the strip bottom plate 9 and the box body 17, flowing through the window 16, and then flowing into the sewer outside, that is, flowing into other places such as the ground; avoid the problem that the water flow cannot be smoothly discharged and wet the ground.
[0046] The large-flow removable core floor drain provided by the embodiment of the application has the following part assembly mode and connection relationship: the sealing ring 11 is placed on the bottom ring 15, the cut strip bottom plate 9 is placed in the box body 17 and attached to the sealing ring 11, and the lower water core 10 extends downward through the window 16; the screw rod of the fastening screw 7 passes through the pressing piece 5, and then the pressing piece 5 aligns the center of the fastening screw 7 with the screw hole 14; at this time, the wedge-shaped piece 8 is placed directly below the positioned pressing piece 5, the thick edge of the wedge-shaped piece 8 is attached to the inner wall of the side frame 12 of the box body 17, the thin edge faces inward, and then the fastening screw 7 is tightened; as the screw rod of the fastening screw 7 enters the screw hole 14, the screw head is stopped and pressed on the limiting hole 6 of the pressing piece 5, so that the fastening screw 7 pulls the pressing piece 5 downward to the high position of the wedge-shaped piece 8. At this time, the wedge-shaped piece 8 applies pressure to the strip bottom plate 9 close to the bottom, and the pressure is further transmitted, so that the flexible sealing ring 11 clamped between the strip bottom plate 9 and the bottom ring 15 realizes the sealing between the box body 17 and the strip bottom plate 9, and can prevent water flow from flowing between the box body 17 and the strip bottom plate 9 to the outside of the box body 17. After the four fastening screws 7 are respectively tightened, the filter screen 4 is placed on the pressing piece 5, and the filter screen 4 can be taken at any time and is not affected by the fastening screw 7 and the pressing piece 5; based on this, the strip bottom plate 9 is detachably fixed in the box body 17. The cover plate 1 is supported on the layer table 13 in the box body 17 through the stand 3, and the top surface of the cover plate 1 is in the same plane as the top surface of the box body 17.
[0047] Based on the above description, it can be clearly determined that the cut strip bottom plate 9 needs to be placed in the box body 17, which has a clear limitation on the size of the cut strip bottom plate 9.
[0048] Firstly, the size of the cut strip core bottom plate 9 must be larger than the size of the window 16, that is, the length and width of the cut strip core bottom plate 9 must be larger than the length and width of the window 16; if the size of the strip core bottom plate 9 is equal to or smaller than the size of the window 16, the cut strip core bottom plate 9 cannot be effectively placed in the box body 17 and will fall from the window 16, or cannot be effectively sealed by the sealing ring 11, resulting in water leakage defects.
[0049] The size of the cut strip core bottom plate 9 must be smaller than the size of the outermost top surface of the bottom ring 15, that is, the side length of the cut strip core bottom plate 9 must be smaller than the outer edge length of the top surface of the bottom ring 15. Otherwise, the cut strip core bottom plate 9 cannot be placed in the designated position of the box body 17 and cannot be in contact with the sealing ring 11. As the shape and size of the top surface of the known bottom ring 15 are the same as those of the sealing ring 11, it can be known that the size of the cut strip core bottom plate 9 must be smaller than the outer edge length of the sealing ring 11. In order to facilitate placement and removal, the side length of the cut strip core bottom plate 9 is preferably about 0.5 mm smaller than the outer edge length of the top surface of the bottom ring 15 in the box body 17.
[0050] In order to achieve the purpose of wall-mounted floor drain, in other words, in order to determine the cutting position of the strip core bottom plate 9, the following method can be used for cutting. The following method is well known and very simple and easy to think of, and has been widely used in many technical fields. Using this method does not require any creative effort from those skilled in the art, and ordinary workers with no cultural level can also complete the cutting work. Please refer to Figure 7 , Figure 7 The schematic diagram of the floor drain when the floor drain can be wall-mounted on both sides for the corner position of the sewer pipe between the two walls.
[0051] Figure 7 In the above, a and b are two walls, and the red box represents the strip core bottom plate 9 before cutting. At this time, the sewer core 10 is located at the center of the strip core bottom plate 9. The dashed line represents the cutting line of the strip core bottom plate 9, that is, the part framed by the dashed line is the shape of the cut strip core bottom plate 9. At this time, the sewer core 10 is located at the upper right corner of the cut strip core bottom plate 9. It can be seen that at this time, the two sides of the side frame 12 of the floor drain box body 17 are respectively attached to the a wall and the b wall, and the sewer core 10 is eccentric within the window 16 relative to the floor drain box body 17.
[0052] The floor drain can be wall-mounted on both sides:
[0053] S1, place the box body 17 on the ground, that is, the bottom surface of the bottom ring 15 is attached to the ground, pass the sewer pipe through the window 16, move the box body 17 so that any two outer surfaces of the side frame 12 are respectively attached to the a wall and the b wall, measure the vertical distance from the center of the sewer pipe to the outer edge of the bottom ring 15 in the direction of the a wall, and record it as La. Measure the vertical distance from the center of the sewer pipe to the outer edge of the bottom ring 15 in the direction of the b wall, and record it as Lb.
[0054] S2, the drain core 10 is placed towards the ground direction with the core bottom plate 9 also being pasted on both walls, the direction is consistent with the box body 17, on the core bottom plate 9, a perpendicular line is drawn from the center of the drain core 10 to the edge line in the a wall direction, the length La is measured on the perpendicular line from the center of the drain core 10 as the starting point, a point is marked, then a straight line parallel to the edge line in the direction is drawn through the point, the line is marked as a1 line, and a straight line parallel to the edge line in the b wall direction is drawn on the core bottom plate 9 by the same method, the line is marked as b1 line.
[0055] S3, the sealing ring 11 is taken out and placed on the core bottom plate 9, two adjacent outer edges of the sealing ring 11 are respectively aligned with the a1 line and the b1 line, the sealing ring 11 is fixed and not moved, then another two straight lines are drawn on the other two outer edges of the sealing ring 11; the four lines form a square, the square is marked as Q1. The square is the maximum size for cutting the core bottom plate 9, as described above, the Q1 line is reduced by about 0.5 mm, the best cutting is achieved, and the core bottom plate 9 is convenient to take and place.
[0056] S4, the step is not a necessary step, only for further description. As shown in step S3, when the outer edge of the sealing ring is close to the Q1 line, another square Q2 with the same side length as the window 16 can be drawn along the inner edge of the sealing ring 11. It is noted that Q2 is the minimum size (limit size) for cutting, and the core bottom plate 9 cannot be equal to or less than the Q2 line when cutting. The Q2 line is only used as a reference to avoid not meeting the quality requirements when cutting.
[0057] The floor drain with only one side pasted on the wall requires a simpler cutting method, which can refer to the above method, and will not be described here.
[0058] The above only describes preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
