Description

Technical Field

[0001] The utility model relates to the field of building drainage, in particular to a downward-draining high-efficiency long-strip floor drain.

Background Art

[0002] The long-strip floor drain has high water collection efficiency, is convenient for the construction of the ground slope, and has an outstanding decorative effect, and is widely used in the shower area of buildings. To prevent hair from falling into the drainage pipe and causing blockage, like other types of floor drains, the long-strip floor drain is generally provided with a filter screen. However, the filtering efficiency of the filter screen of the existing long-strip floor drain does not match its water collection efficiency (low filtering efficiency), making the floor drain prone to blockage (requiring frequent cleaning); in addition, the structure of its filter screen is flat or the area is narrow, resulting in poor hair collection effect and being difficult to clean, affecting the user experience.

Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a downward-draining high-efficiency long-strip floor drain, which has high filtering efficiency, is not easy to block, has a good hair collection effect, is easy to clean, and truly improves the user experience.

[0004] The purpose of the utility model is realized as follows:

[0005] A downward-draining high-efficiency long-strip floor drain includes a long-strip water collection tank with a high surrounding and a low middle, and a water outlet is arranged at the bottom of the tank. A filter tank with a high surrounding and a low middle is installed in the tank cavity of the water collection tank. A cover plate covers the tank opening of the water collection tank, and water collection holes opposite to the tank opening of the filter tank are opened on the plate surface of the cover plate. The tank cavity of the water collection tank extends along the length direction of the water collection tank and is long-strip shaped. There is one or more than two filter tanks, which extend or are arranged along the length direction of the tank cavity of the water collection tank, and there is a water passing gap between the filter tank and the water outlet.

[0006] The filter tank of the long-strip floor drain has a high surrounding and a low middle, and extends or is arranged along the length direction of the tank cavity of the water collection tank. This structure is conducive to maximizing the filtering area of the filter tank (having the structural basis for maximizing the filtering area), with high filtering efficiency and not easy to block (extending the cleaning and maintenance cycle); at the same time, the hair is intercepted by the filter tank and collected in its tank cavity, with a good hair collection effect and easy to clean, that is, the long-strip floor drain takes into account both the filtering efficiency and the hair collection effect (high efficiency), killing two birds with one stone.

[0007] For the long-strip floor drain as described above, a secondary filter screen is installed at the front end of the water outlet, and the filter tank and the secondary filter screen together form a secondary filtering structure, which is conducive to the filtering effect.

[0008] The strip-shaped floor drain as described above has an overflow gap communicating with the water passing gap left between the notch of the filtering tank and the bottom surface of the cover plate. When the inflow is greater than the filtering equivalent of the filtering tank, it can avoid or slow down the drainage failure of the floor drain, which is beneficial to the stability and reliability of filtering.

[0009] The strip-shaped floor drain as described above is equipped with an air separation device at the rear end of the water outlet, so that the strip-shaped floor drain has the function of preventing odor and separating air.

[0010] The strip-shaped floor drain as described above has a filtering tank formed by enclosing a bottom plate and side plates. The bottom plate and the side plates are both provided with filtering holes to ensure the effective filtering area of the filtering tank and perform three-dimensional filtering, which is beneficial to the filtering efficiency and equivalent.

[0011] The strip-shaped floor drain as described above has a concave upward bulge on the bottom plate, which increases the size of the water passing gap and is beneficial to the filtering and water passing efficiency.

[0012] The strip-shaped floor drain as described above has a handle provided outward on the side plate, which is convenient for disassembly and does not interfere with the collection and cleaning of the filtering tank when set outward.

[0013] The strip-shaped floor drain as described above is provided with several brackets between the filtering tank and the water collection tank for lifting it in the cavity of the water collection tank and limiting it in the middle of the cavity width direction and / or length direction of the water collection tank, ensuring the size of the water passing gap and being beneficial to the filtering and water passing efficiency.

[0014] The strip-shaped floor drain as described above has more than two brackets, which are arranged inside the water collection tank. The filtering tank is clamped inside the more than two brackets, with a simple structure and being beneficial to the implementation efficiency of the filtering tank.

[0015] The strip-shaped floor drain as described above has several strip-shaped feet provided downward at the edge of the cover plate for lifting it on the notch of the water collection tank. The feet support on the brackets, or the feet are provided with notches for avoiding the brackets and support on the inner bottom of the water collection tank. The cover plate is stably and reliably assembled, with a compact structure and being beneficial to the application range of the strip-shaped floor drain.

[0016] The strip-shaped floor drain as described above has only one water collection hole, which extends along the length direction of the cover plate and is provided with several outward-expanded lifting holes for fingers to reach, taking into account the water collection efficiency, the appearance aesthetics and the disassembly convenience, and not blocking or hanging hair.

Specific embodiments

[0023] To better understand the above technical solutions, the exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings, which are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0024] A down-drain type high-efficiency long-strip floor drain includes a long-strip-shaped water collection tank 1 with a high surrounding and a low middle, and a water outlet 11 provided at the bottom of the tank. A number of filter tanks 2 with a high surrounding and a low middle are installed in the tank cavity of the water collection tank 1. A cover plate 3 covers the tank opening of the water collection tank 1. A water collection hole 31 opposite to the tank opening of the filter tank 2 is opened on the plate surface of the cover plate 3. The tank cavity of the water collection tank 1 extends along the length direction of the water collection tank 1 and is long-strip-shaped. When there is only one filter tank 2, it extends along the length direction of the tank cavity of the water collection tank 1. When there are two or more filter tanks 2, they are arranged along the length direction of the tank cavity of the water collection tank 1. Regardless of the number of filter tanks 2, a water passing gap 4 is left between them and the water outlet 11.

[0025] To balance the structural compactness and implementation efficiency, the number of filter tanks 2 can be determined according to the length of the tank cavity of the water collection tank 1. For the convenience of description, there is only one filter tank 2 in this embodiment. As Figure 1 and Figure 2As shown, the filtering tank 2 is high around and low in the middle (with a tank cavity structure), and extends along the length direction of the tank cavity of the water collecting tank 1 (usually in a long strip shape). This structure provides a structural basis for maximizing the filtering area (facilitating the maximization of the filtering area), with a large filtering area (a large total area after expansion), high filtering efficiency, and is not easily blocked (long cleaning and maintenance cycle); the water passing gap 4 is for the filtered water to fall to the water outlet 11, and its position can be diverse. It can be formed between the bottom or side of the filtering tank 2 and the water outlet 11, or between the bottom and side of the filtering tank 2 and the water outlet 11; during use, the sewage falls into the filtering tank 2 from the water collecting hole 31. After filtering, it is discharged into the drainage pipe through the water passing gap 4 from the water outlet 11. In particular, the hair in the sewage is intercepted and collected in the tank cavity of the filtering tank 2, with good hair collection effect and easy to clean. This long strip floor drain is also beneficial to the filtering efficiency and the hair collection effect (the high efficiency described in the theme of this utility model means high filtering efficiency and good hair collection effect). To facilitate the water collection efficiency, there is one or more than one water collecting hole 31, which extends or distributes along the length direction of the cover plate 3; to meet the diverse needs, there can also be one or more than one water outlet 11; to facilitate the structural compactness, the notch of the filtering tank 2 does not protrude above the notch of the water collecting tank 1, that is, the filtering tank 2 does not exceed the range of the tank cavity of the water collecting tank 1.

[0026] To facilitate the filtering effect, a secondary filter screen 5 is installed at the front end of the water outlet 11, as Figure 1 , Figure 3 and Figure 4 shown. The secondary filter screen 5 with a secondary filter hole 51 opened on the screen body is in the shape of a sieve plate and covers the water outlet 11; the secondary filter screen 5 and the filtering tank 2 together form a secondary filtering structure. During use, the sewage falls into the filtering tank 2 from the water collecting hole 31. After the primary filtering, it falls to the secondary filter screen 5 through the water passing gap 4. After the secondary filtering, it is discharged into the drainage pipe from the water outlet 11. This secondary filtering structure improves the overall filtering effect. Of course, the structural style and installation method of the secondary filter screen 5 can both be diverse, such as in the shape of a sieve tube and embedded in the water outlet 11.

[0027] To facilitate the filtering stability, there is an overflow gap 6 communicating with the water passing gap 4 left between the notch of the filtering tank 2 and the bottom surface of the cover plate 3, as Figure 3 and Figure 4As shown, an overflow gap 6 is formed between the top edge of the flat-mouth filter tank 2 and the bottom surface of the cover plate 3. During use, when the inflow exceeds the filtration equivalent of the filter tank 2, sewage (or part of the sewage) overflows from the overflow gap 6, falls to the secondary filter screen 5 through the water passing gap 4, and after filtration, is discharged into the drainage pipe through the water outlet 11. This structure improves the reliability of the overall filtration and avoids (or slows down) the drainage failure of the floor drain due to the blockage of the filter tank 2; this structure can also prevent the filter tank 2 from interfering with the covering of the cover plate 3 and the water collection tank 1. The form of the overflow gap 6 can be diverse. Any void or channel that allows sewage (or part of the sewage) to overflow from the notch of the filter tank 2 (and fall to the secondary filter screen 5 through the water passing gap 4) when the inflow exceeds the filtration equivalent of the filter tank 2, and even the assembly gap to avoid interfering with the covering of the cover plate 3 and the water collection tank 1, belongs to the scope of the overflow gap 6; similarly, the form of the water passing gap 4 can also be diverse. Any void or channel that allows sewage to fall from the filter tank 2 (after filtration) to the water outlet 11, and even the assembly gap between the filter tank 2 and the water collection tank 1, belongs to the scope of the water passing gap 4.

[0028] Regardless of whether the secondary filter screen 5 or the overflow gap 6 is provided, for the sake of using comfort, an air separation device 7 is installed at the rear end of the water outlet 11, such as Figure 1 , Figure 3 and Figure 4 shown. The air separation device 7 is a self-sealing floor drain core and is embedded inside the water outlet 11 to prevent the odor in the drainage pipe from overflowing. Of course, the structural style and installation method of the air separation device 7 can be diverse, such as a water seal structure (external type) for the water outlet 11 to fit into.

[0029] For the sake of filtration efficiency, the filter tank 2 is formed by enclosing a bottom plate 21 and side plates 22, and both are provided with filter holes 23, such as Figure 1 and Figure 2 shown. The filter tank 2 includes a bottom plate 21 and side plates 22 that extend upward along the periphery of the bottom plate 21. Both the bottom plate 21 and the side plates 22 are provided with filter holes 23, increasing the effective (vertical) filtration area, achieving three-dimensional filtration with a high filtration equivalent. Regardless of the structural style of the filter tank 2, the water passing gap 4 between it and the water outlet 11 is the water passing gap 4 between the filter holes 23 and the water outlet 11.

[0030] For the sake of water passing efficiency, the bottom plate 21 is provided with an upward concave bulge 211, such as Figure 3 and Figure 4 shown. The bulge 211 increases the size of the water passing gap 4 between the bottom (bottom plate 21) of the filter tank 2 and the inner bottom (water outlet 11) of the water collection tank 1. Further, as Figure 1 and Figure 2 shown, the bulge 211 extends along the extension (length) direction of the filter tank 2 and is in the shape of a reinforcing rib. Therefore, it is also beneficial to the structural strength of the filter tank 2.

[0031] Regardless of whether the bottom plate 21 is provided with a bulge 211, for the convenience of disassembly, a handle 221 is provided outwardly on the side plate 22. As Figure 1 and Figure 2 shown, the handles 221 are provided on the outer sides of both ends in the extending (length) direction of the filter tank 2, without interfering with collection and cleaning. Of course, the structural style of the filter tank 2 can be diverse. Preferably, as Figure 5 shown, the filter tank 2 is formed by enclosing a bottom plate 21 and side plates 22 extending upward along the periphery of the bottom plate 21. The style and arrangement of the filter holes 23 can be set as required.

[0032] Regardless of the structural style adopted by the filter tank 2, for the purpose of (further) facilitating filtration and water passing efficiency, a number of brackets 12 are provided between the filter tank 2 and the water collection tank 1 for lifting it in the cavity of the water collection tank 1 (lifting function) and limiting it in the middle of the cavity width direction and / or length direction of the water collection tank 1 (limiting function). This structure ensures the size of the water passing gap 4. The structural style of the brackets 12 can be diverse. Its two functional parts can be integrated or separated. They can be provided on the water collection tank 1, or on the filter tank 2, or separately on both of them, or even be independent parts. Any structure provided between the filter tank 2 and the water collection tank 1 for the purpose of lifting the filter tank 2 in the cavity of the water collection tank 1 and limiting it in the middle of the cavity width direction and / or length direction of the water collection tank 1 belongs to the scope of the brackets 12. Of course, if the brackets 12 are not provided between the filter tank 2 and the water collection tank 1, the water passing gap 4 can still be formed by the shape or size of the body structure of the filter tank 2, or the shape or size of the body structure of the water collection tank 1, that is, the water passing gap 4 can completely be formed without the brackets 12.

[0033] For the sake of the overall structural compactness and the implementation efficiency of the filter tank 2, there are more than two brackets 12, which are provided on the inner side of the water collection tank 1, and the filter tank 2 is snap-fitted inside the more than two brackets 12. As Figure 1 、 Figure 3 and Figure 4 shown, the more than two brackets 12 are all L-shaped and are provided on the two inner sides in the length direction of the water collection tank 1. The filter tank 2 is snap-fitted inside them (the more than two brackets 12 lift the filter tank 2 in the cavity of the water collection tank 1 and limit it in the middle of the cavity width direction of the water collection tank 1), that is, at least a water passing gap 4 is formed between the inner bottom of the filter tank 2 and the water collection tank 1 and the two inner sides in the length direction.

[0034] Regardless of the structural styles of the filter tank 2 and the bracket 12, to facilitate the structural strength (closing reliability) of the cover plate 3, several strip-shaped feet 32 are provided downward at the edges of the cover plate 3. On this basis, there are at least two ways to close the cover plate 3 and the water collecting tank 1. First, the feet 32 are supported on the bracket 12, and the cover plate 3 is lifted above the notch of the water collecting tank 1. This structure is particularly suitable for the water collecting tank 1 made of copper material (red punching process). Second, the feet 32 are provided with notches 321 for avoiding the bracket 12, which are supported on the inner bottom of the water collecting tank 1, and the cover plate 3 is lifted above the notch of the water collecting tank 1. This structure is particularly suitable for the water collecting tank 1 made of steel material (bending process). The water collecting tank 1 and the cover plate 3 in this embodiment are both made of steel material. As Figures 1 to 4 shown, the feet 32 are of a flanging structure and are respectively arranged at the two side edges in the length direction of the cover plate 3. The two feet 32 are provided with notches 321 and are supported on the inner bottom of the water collecting tank 1. After the cover plate 3 is closed, the filter tank 2 is located inside the two feet 32.

[0035] Regardless of the closing method between the cover plate 3 and the water collecting tank 1, to facilitate the water collecting efficiency and prevent hair from getting stuck, there is only one water collecting hole 31, which extends along the length direction of the cover plate 3. Further, for easy disassembly, the water collecting hole 31 is provided with several outwardly expanding lifting holes 311 for fingers to reach into. As Figure 1 and Figure 2 shown, there are two lifting holes 311, both of which are circular and are respectively arranged at positions adjacent to the ends of the water collecting hole 31. The plate surface structure of the cover plate 3 is compact and the appearance is simple.

[0036] Overall, the long-strip floor drain has a simple and compact structure. The filter tank 2 has a large filtering area, high filtering efficiency, and is not easily blocked. The grooved structure of the filter tank 2 has a good hair collecting effect and is easy to clean. The water collecting tank 1 in this embodiment is rectangular. Based on the equivalent principle, the present utility model is also applicable to long-strip floor drains with the water collecting tank 1 in other shapes.
