Description

Technical Field

[0001] The invention belongs to the technical field of floor drains, and in particular relates to a multi-purpose and overflow-proof floor drain. Background Art

[0002] Floor drains are a common drainage device used in everyday life, such as bathrooms and balconies. They collect accumulated water and drain it into sewage pipes, ensuring a clean and dry floor. Existing floor drains are mostly single-purpose, serving only to collect and drain accumulated water. To drain wastewater from washing machines or basins, a dedicated drainage channel must be installed, resulting in a complex and inconvenient structure.

[0003] In order to solve the above problems, some multi-purpose floor drains have appeared on the market, which can collect and discharge the accumulated water on the ground and the sewage from the washing machine or the basin sewer pipe at the same time. For example, a washing machine floor drain joint assembly proposed by Chinese utility model patent CN206873133U has a washing machine drain pipe joint provided in the middle of the floor drain, so that the sewage generated by the washing machine can flow into the floor drain along the drain pipe joint. At the same time, a leakage hole is provided on the surface of the floor drain, and the sewage on the ground can enter the floor drain along the leakage hole for unified drainage. Although the technical solution provided in the aforementioned existing patent can solve the above problems, since the drainage port of the drainage pipe joint is directly located on the floor drain cover, the two drainage channels are directly combined into one in the floor drain, that is, the sewage from the washing machine and the sewage on the ground will directly merge in the floor drain. In actual use, the sewage from the washing machine is usually a relatively large and rapid water flow. During the drainage process, it is easy to overflow from the leakage hole on the floor drain cover, so the drainage effect is not good. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the floor drain of the present invention is described in detail below with reference to the embodiments and drawings.

[0032] <Example 1>

[0033] Figure 1 It is a structural diagram of a floor drain according to embodiment 1 of the present invention.

[0034] Figure 2 It is a cross-sectional view of the floor drain according to Example 1 of the present invention.

[0035] like Figure 1 and Figure 2As shown, this embodiment provides a floor drain 100, comprising a housing 10, a partition 20, a floor drain core 30, a drain 40, and a cover plate 50. The housing 10 has a mounting portion 11 and a first drain portion 12. The first drain portion 12 is provided with a first drain channel 13, and a sealing ring for installation is provided on the outside. The partition 20 is provided in the mounting portion 11, and is used to separate the interior of the mounting portion 11 into at least two independent water collection areas (two in this embodiment). These two independent water collection areas include a first water collection area 14 and a second water collection area 15. The floor drain core 30 is mounted on the partition 20 and has a second drain portion 31 built into the first drain channel 13 of the first drain portion 12. The second drain portion 31 is provided with a second drain channel 32. The first water collection area 14 is connected to the first drain channel 13, and the second water collection area 15 is connected to the second drain channel 32. The cover plate 50 is mounted on the top of the mounting portion 11 and has a drain hole 51 leading to the second water collection area 15. The drain 40 is mounted on the partition 20 and has a water outlet 412 leading to the first water collection area 14. Sewage from the ground flows through the drain hole 51 on the cover plate 50 into the second water collection area 15 and then flows out to the sewage pipe along the second drain channel 32 (see FIG. Figure 2 The drain 40 is provided with a water inlet 411 which can be connected to a drainage pipe joint of a washing machine or a basin, etc. The sewage from the washing machine or the basin enters the first water collection area 14 from the drain 40 and then flows out to the sewage pipe along the first drain channel 13 (see Figure 2 (The direction of water flow is indicated by the thin arrow in the figure). Since the first water collection area 14 and the second water collection area 15 are independently provided and are respectively connected to the first sewer channel 13 and the second sewer channel 32, which are also independently provided, two independent sewer flow channels 1 and 2 are formed. Sewage from different locations can be drained separately without interfering with each other, thereby greatly reducing the overflow of the floor drain.

[0036] Figure 3 This is a structural diagram of the partition portion of Example 1 of the present invention.

[0037] Figure 4 This is a cross-sectional view of the partition portion of Example 1 of the present invention.

[0038] like Figure 3 and Figure 4As shown, the partition 20 has a flat partition plate 28, the middle of the partition plate 28 is recessed downward to form a mounting opening 21, and the floor drain core 30 is detachably mounted in the mounting opening 21; one side of the partition plate 28 located at the mounting position 21 is convex upward to form a mounting boss 22, and the drain 40 is detachably mounted on the mounting boss 22, and the cover plate has a shape that matches the mounting boss 22, so that when the cover plate 50 is covered on the mounting portion, the top surface of the cover plate 50 is flush with the top surface of the mounting boss 22. Specifically, as shown in FIG. Figure 2 As shown, the partition plate 28 divides the interior of the mounting portion 11 of the housing 10 into two upper and lower water collection areas. The partition plate 28 serves as the boundary, and the area between the upper side of the partition plate 28 and the cover plate forms the second water collection area 15. The area between the lower side of the partition plate 28 and the bottom plate of the housing 10 forms the first water collection area 14. The second drain portion 31 is in the shape of a waist-shaped cylinder with a concave center. The upper end is mounted in the mounting opening 21 and a sealing ring 33 is provided between the mounting opening 21. The lower end is removably provided with an odor-proof core 34 for odor-proofing the second drain channel. A mounting hole 23 is provided in the middle of the mounting boss 22. An annular protrusion 24 is provided in the mounting hole 23. A notch-shaped bayonet 241 is provided on the annular protrusion 24. A mounting block 415 is provided on the outer periphery of the water outlet 412 of the drain 40 corresponding to the bayonet 241. The drain 40 is mounted in the mounting hole 23 by rotating and snapping. Specifically, when installing the drain 40, first align the installation block 415 with the bayonet 241 and insert it. Then, rotate the drain 40 so that the installation block 415 snaps into place below the annular protrusion 24. The annular protrusion 24 blocks the installation block 415. At any angle, as long as the installation block 415 is below the annular protrusion 24, the drain 40 cannot fall out. Removal is only possible when the installation block 415 is aligned with the bayonet 241. Therefore, the bayonet 241 can be positioned at an angle that is not often used by users to prevent the drain 40 from easily falling out during use. In actual situations, threaded installation can also be used.

[0039] In this embodiment, the partition 20 and the housing 10 are provided separately and fixed together using a fixing member. A sealing member 25 is provided between the partition 20 and the housing 10 (this can be in the form of a sealing ring provided between the side of the partition 20 and the inner wall of the housing 10, or in the form of a sealing gasket provided between the bottom surface of the partition 20 and the bottom surface of the housing 10) to enhance the sealing performance, thereby allowing the first water collection area 14 and the second water collection area 15 to form independent spaces, thereby preventing the sewage in the two areas from mixing. In addition, a fixing boss 26 is provided at the edge of the partition 20, and a fixing hole 27 for accommodating the fixing member is provided in the fixing boss 26. When the cover plate 50 is placed on the housing 10, the cover plate 50 is placed on the upper edge of the fixing boss and covers the fixing member. The fixing member is generally made of metal materials such as screws. The fixing boss 26 and the covering of the cover plate 50 can prevent the fixing member from rusting, corroding, etc. A ridge 29 is also provided at the edge of the partition 20 and / or the edge of the mounting boss 22, and the cover plate 50 is directly placed on the ridge 29. When the cover plate 50 is placed on the ridge 29, the top surface of the cover plate 50, the top surface of the mounting boss 22 and the top surface of the shell 10 are flush.

[0040] Figure 5 It is a structural diagram of the drainer according to embodiment 1 of the present invention.

[0041] Figure 6 It is a cross-sectional view of the drainer according to embodiment 1 of the present invention.

[0042] like Figure 5 and Figure 6 As shown, the drain 40 of this embodiment is an odor-proof drain, comprising a main body 41 with a hollow interior and a cylinder 42 disposed inside the main body 41. The main body 41 is provided with a water inlet 411 and a water outlet 412. The water inlet 411 can be provided in the form of a water inlet interface for connecting to a water inlet joint, and the water outlet 412 is located at the bottom of the main body 41 for discharging water. Figure 6 As shown, the barrel 42 and the main body 41 are integrally formed. An inner flow channel 421 is axially defined in the middle of the barrel 42. An outer flow channel 431 is provided between the outer periphery of the barrel 4421 and the inner wall of the main body 41, communicating with the inner flow channel 421. A deodorizing element 44 is movably disposed at the connection between the inner and outer flow channels 421 and 431. The deodorizing element 44 has an open state, connecting the inner and outer flow channels 421 and 431, and a closed state, blocking the inner and outer flow channels 421 and 431. The inner and outer flow channels 421 and 431 are arranged substantially coaxially with the main body 41, or their axes are parallel. The inner flow channel 421 is located within the outer flow channel 431, separated by the barrel 42. In practice, the barrel 42 and the main body 41 may also be separate bodies. In this case, a sealing ring is required between the barrel 42 and the main body 41 to separate the outer and inner flow channels.

[0043] In this embodiment, if Figure 6 As shown, the inner flow channel 421 is connected with the water outlet portion 412 to form a water outlet channel, which has a first water inlet 422 and a first water outlet 423. The first water outlet 423 leads to the water outlet portion 412, which is the upper end and the lower end of the inner flow channel 421; the outer flow channel 431 is connected with the water inlet portion 411 to form a water inlet channel, which has a second water inlet 432 and a second water outlet 433. The normal drainage direction is: water flows into the water inlet portion 411, flows through the water inlet channel from the second water inlet 432 and flows out from the second water outlet 433, then enters the water outlet channel from the first water inlet 422 after flowing out, and finally flows through the first water outlet 423 and flows out from the water outlet portion 412.

[0044] Figure 7 This is a cross-sectional view of the annular diaphragm installed on the main body in Example 1 of the present invention.

[0045] Figure 8 It is a cross-sectional view of the main body of Example 1 of the present invention.

[0046] like Figure 7-Figure 8 As shown, a first mounting protrusion 424 is formed on the outer wall of the cylinder 42 at one end near the first water inlet 422. A second mounting protrusion 413 corresponding to the first mounting protrusion 424 is provided on the inner wall of the main body 41 at the second water outlet 433. The deodorizing element 44 is movably mounted on the first mounting protrusion 424 and the second mounting protrusion 413. Specifically, in this embodiment, the first mounting protrusion 424 and the second mounting protrusion 413 are both inclined toward the bottom of the water inlet channel, forming a conical annular surface. The deodorizing element 44 is an annular diaphragm with an arc-shaped cross-section and a downwardly concave center. The bottom surface facing the water inlet channel is an arc-shaped surface, and the two ends of the arc-shaped surface are respectively used to abut against the first mounting protrusion 424 and the second mounting protrusion 413. When water flows from the second water outlet 433 to the first water inlet 422, the water flow pushes the anti-odor element to at least partially leave the first mounting protrusion 424 and / or the second mounting protrusion 413 and put it in the open state, and the water flow can flow smoothly from the second water outlet 433 to the first water inlet 422; when there is no water flow or the water flow overflows from the first water inlet 422 and flows to the second water outlet 433, the anti-odor element 44 will be in a closed state against the first mounting protrusion 424 and the second mounting protrusion 413 under its own gravity or water pressure, separating the water inlet channel and the water outlet channel, preventing water from overflowing back into the water inlet channel, and also preventing odor from overflowing, thereby playing a role in preventing odor and sewage from overflowing.

[0047] In this embodiment, the annular diaphragm can be made of rubber, which has a certain hardness and quality. In the absence of external forces, gravity allows its bottom surface to rest directly on the first mounting protrusion 424 and the second mounting protrusion 413, forming a closed state. If water flows from the bottom and the impact force exceeds the weight of the annular diaphragm, the annular diaphragm will be pushed open, creating a gap between the bottom surface of the annular diaphragm and the first mounting protrusion 424 and the second mounting protrusion 413, thereby opening the channel for water to flow through. When water overflows from the first water inlet 422 of the water outlet channel, the water flow exerts downward pressure on the annular diaphragm, further pressing its bottom surface against the first mounting protrusion 424 and the second mounting protrusion 413, thus forming a closed state and preventing water and odor from escaping. The use of rubber ensures that the bottom surface of the annular diaphragm and the first mounting protrusion 424 and the second mounting protrusion 413 have good contact and sealing properties.

[0048] In addition, in actual circumstances, one side of the annular diaphragm can be fixed to the first mounting protrusion 424 or the second mounting protrusion 413, while the other side forms an open structure with the corresponding second mounting protrusion 413 or the first mounting protrusion 424. The water flow only flushes open the open side, and the conduction between the water inlet channel and the water outlet channel can also be achieved.

[0049] like Figure 8 As shown, the water inlet 411 is at least one side water inlet (one in this embodiment, but more can be provided in actual situations) provided on the side of the main body 41, and a second water inlet 432 connected to the side water inlet is formed on the side of the water inlet channel. At the same time, the height of the side water inlet is lower than the height of the deodorizing element 44, the height of the first water inlet 422 is higher than the height of the deodorizing element 44, and the height of the first water outlet 423 is lower than the height of the deodorizing element 44, so that water can flow smoothly and the deodorizing element can achieve better deodorizing and anti-overflow effects. At the same time, see Figure 6 The outer flow channel 431 (i.e., the water inlet channel) has an open end and a closed end. The open end is the second water outlet 433, and the bottom of the closed end is slightly lower than the bottom of the water inlet 411, so that a water seal can be formed at the closed end, further improving the anti-odor and anti-overflow effects.

[0050] like Figure 6 and Figure 8As shown, the main body 41 also has an opening 414 leading to the deodorizing element 44. A cap 45 is attached to the opening 414 via a threaded cover. When the deodorizing element 44 needs to be replaced or cleaned, the cap 45 can be removed, removed from the opening 414 for cleaning or replacement, and then replaced and capped, making it very convenient. A sealing ring is provided between the cap 5 and the inner wall of the opening 14. Furthermore, a mounting block 415 for mounting the main body 41 is provided at one end of the main body 41 located at the water outlet 412. By attaching the main body 41 to the floor drain via the mounting block 415, the main body 41 is ready for use.

[0051] This embodiment adopts two independent internal and external sewer channels, and both sewer channels are respectively provided with an anti-odor device (anti-odor core and anti-odor element), so that the two sewer channels can not only drain water independently without interfering with each other, but also carry out all-round anti-odor and anti-overflow, with better effect.

[0052] <Example 2>

[0053] Figure 9 Schematic diagram of the water flow direction of the drain in embodiment 2 of the present invention.

[0054] This embodiment is basically the same as the above-mentioned embodiment 1, except that the outer flow channel 431 and the inner flow channel 421 of the drain 40 are in opposite positions, that is, the outer flow channel 431 is connected to the water outlet 412 to form a water outlet channel, while the inner flow channel 421 is connected to the water inlet 411 to form a water inlet channel. In this case, the drain of this embodiment also includes a guide sleeve 46 arranged inside the main body 41. The guide sleeve 46 is an annular cylindrical structure with a closed bottom and an open top. The bottom of the cylinder 42 is inserted into the guide sleeve 46 (or the two are arranged in one piece), and a through hole 425 leading to the inside of the guide sleeve 46 is opened on the wall of the cylinder 42. The water outlet channel is provided between the outer periphery of the guide sleeve 46 and the inner wall of the main body 41, and the deodorizing element 44 is installed between the outer wall of the cylinder 42 and the inner wall of the guide sleeve 46. The water flow direction is as follows: Figure 5 As shown in , the connection and blocking of the water inlet and outlet channels are the same as those in the above-mentioned embodiment 1. In this embodiment, the length of the guide sleeve 46 along the axis is less than the length of the cylinder 42 along the length direction, so that the water flow can form a water seal in the guide sleeve 46, further improving the anti-odor and anti-overflow effects.

[0055] <Example 3>

[0056] Figure 10 2 is a schematic diagram of the floor drain structure of embodiment 3 of the present invention.

[0057] In this embodiment, based on the above-mentioned embodiment 1, a plurality of water inlets 411 are provided on the main body 41 of the drainer 40. The interiors of the plurality of water inlets 411 all lead to water inlet channels, which can be used to connect the drain pipes of multiple washing machines or basins.

[0058] <Example 4>

[0059] Figure 11 It is a cross-sectional view of the floor drain structure of Example 4 of the present invention.

[0060] In this embodiment, based on the above-mentioned embodiments 1 to 3, a filter basket 60 is removably provided at the upper opening of the second drainage portion 31, i.e., at the location connected to the partition 20, to filter the sewage from the second water collection area 15 and prevent impurities in the sewage from flowing into the second drainage channel 32 and causing blockage.

[0061] <Example 5>

[0062] Figure 12 This is a structural diagram of the partition portion of Example 5 of the present utility model.

[0063] This embodiment is essentially the same as the aforementioned embodiments 1-4, differing in the mounting arrangement between the cover plate 50 and the partition 20. Several support blocks 52 are provided on the side of the partition 20 facing the cover plate 50, for supporting the cover plate. A notch 53 is provided at the junction of the mounting boss 22 and the main body of the partition 20, for quickly removing the cover plate. The corner of the cover plate fits neatly over the notch 53. To remove the cover plate, the user simply applies force to the area above the gap, causing the other end of the cover plate to tilt up, allowing for quick removal. This is very convenient.

[0064] <Example 6>

[0065] In this embodiment, based on the above-mentioned embodiments 1-5, to prevent the deodorizing element 44 (annular diaphragm) inside the drain from receiving insufficient force during reset, a reset member is provided on one side of the deodorizing element 44 to assist in maintaining the deodorizing element 44 in its closed state. This reset member can be a spring or a torsion spring. If a spring is used, the spring can be installed between the deodorizing element 44 and the cap 45, with one end resting on the upper end surface of the deodorizing element 44. If a torsion spring is used, the torsion spring can be installed between the first mounting protrusion 424 or the second mounting protrusion 413 and the deodorizing element 44, with one end acting on the deodorizing element 44 to facilitate reset. When the deodorizing element 44 is under its own weight or needs to be tilted for use, the deodorizing element 44 can close the channel with the help of elastic force, keeping it in a closed state.

[0067] First, in the above embodiment, since a partition 20 is provided in the mounting portion 11 of the shell 10, the partition 20 divides the interior of the mounting portion 11 into at least two independent water collection areas, and the two independent water collection areas are respectively connected to the first drain channel and the second drain channel to form two independent water channels, so that the two independent water channels can not only achieve the multi-purpose drainage functions of washing machine (or basin, etc.) drainage and ground drainage, but also can be separated independently when collecting water and draining water without affecting each other, thereby avoiding overflow during the drainage process to a great extent.

[0068] Secondly, a separate anti-odor element 46 with anti-odor and anti-backflow functions is provided in the drain 40 of the above embodiment, and an anti-odor core 34 with the same anti-odor and anti-backflow functions is also separately provided on the second drain part 31, so that the two separate water channels each have the anti-odor and anti-backflow functions, further enhancing the anti-odor and anti-backflow functions of the entire device.

[0069] Finally, all components of the above embodiments are connected in a detachable manner, such as between the drain 40 and the partition 20, and between the partition 20 and the floor drain core 30. Such a structure is very convenient for actual users to replace and repair.

[0070] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
