Description

Technical Field

[0001] The present invention belongs to the technical field of floor drain drainage, and particularly relates to a floor drain. Background Art

[0002] With the improvement of living standards, due to people's pursuit of comfort and humanization, there are more and more shower rooms in construction projects, and the anti-drainage construction technology for shower rooms has become increasingly mature.

[0003] Currently, the anti-drainage solution for shower rooms is usually as follows: the wall surface of the shower room is an enamel tile wall surface, the ground is a non-slip floor tile ground, a floor drain is provided on the ground, and a drainage slope of 2-3% is set on the ground to facilitate the drainage of the ground water to the floor drain and then through the floor drain to the sewer pipe. The base layer of the wall and the base layer of the floor slab are coated with waterproof paint to prevent the water seeping through the joints of the wall and floor tiles from entering the wall or the floor slab, and to prevent the leakage of the shower room floor or the alkali efflorescence on the adjacent room wall surface. However, over time, the accumulated water between the floor tile and the ground waterproof coating layer will gradually increase.

[0004] Traditional floor drains can only drain the accumulated water above the floor tiles on the shower room floor and cannot drain the accumulated water that seeps below the floor tiles and above the waterproof layer under long-term action. Since the ground of other adjacent rooms (or corridors) in the shower room is not provided with a waterproof layer, the water seeping from the floor tiles will accumulate to a certain amount over time, and the accumulated water will flow out through the shower room door to below the floor tiles (or wooden floors) of other rooms or corridors, resulting in the leakage of the floor slabs of other rooms or corridors. Summary of the Invention

[0005] The object of the present invention is to provide a floor drain that can not only drain the accumulated water above the floor tiles but also drain the accumulated water between the floor tiles and the waterproof layer, and prevent the accumulated water between the ground and the waterproof layer from flowing out to below the floor tiles of other rooms or corridors.

[0026] The present invention will be described in detail below with reference to the drawings and embodiments.

[0027] Embodiment 1

[0028] Figure 1 It is a longitudinal sectional view of the floor drain of the present invention, Figure 2 It is a top view of the floor drain of the present invention, Figure 3This is an exploded view of each part of the floor drain of the present invention. As Figure 1 , 2 , as shown in Figure 3, a floor drain of this embodiment includes a sand filtering hanging basket 1, an inner funnel 2, a floor drain cover plate 3, and a light annular rubber ring 4. Figure 4 This is a cross-sectional view of the sand filtering hanging basket. As Figure 4 shown, the sand filtering hanging basket 1 is a funnel with a larger upper part and a smaller lower part, and is divided into three parts from top to bottom: a first conical section 12, a frustum section 13, and a second conical section 14. Both the first conical section 12 and the second conical section 14 are frustum-shaped with a larger upper part and a smaller lower part. The bottom of the first conical section 12 is connected to the top of the frustum section 13; the bottom of the frustum section 13 is connected to the top of the second conical section 14, and an annular platform 15 is formed at the top of the second conical section 14; filter holes 16 are provided on the first conical section 12; both the frustum section 13 and the second conical section 14 have no holes. Figure 5 This is an installation schematic diagram of the inner funnel and the floor drain cover plate. As Figure 5 shown, the inner funnel 2 includes a top cover 21 and a funnel part 22; the top cover 21 is a ring fixed on the top of the funnel part 22. The top cover 21 is snap-connected to the top of the sand filtering hanging basket 1, and filter holes 26 are provided on the top cover 21; the bottom of the funnel part 22 is turned outward to form an annular sand filtering groove 23; the bottom of the annular sand filtering groove 23 is located at the top of the frustum section 13 (as Figure 1 shown); filter sand holes 25 are provided at the bottom and the outward-turned part of the annular sand filtering groove 23; the light annular rubber ring 4 is horizontally placed on the annular platform 15. The thickness of the light annular rubber ring 4 is less than the height of the frustum section 13. The bottom of the frustum section 13 is larger than the top, and the inner diameter of the top of the frustum section 13 is the same as the outer diameter of the light annular rubber ring 4. The annular rubber ring 4 can be mated and sealed with the bottom surface of the annular sand filtering groove 23; the floor drain cover plate 3 is covered within the ring of the top cover 21, and drain holes 31 are provided on the floor drain cover.

[0029] Working principle:

[0030] The floor drain of the present invention is installed in a water-rich room during use, such as Figure 1As shown, the accumulated water above the floor tile enters the inner funnel 2 through the drain holes 31 on the floor drain cover plate 3, then passes downward through the hole in the middle of the lightweight annular rubber ring 4 and is discharged from the bottom of the sand filtering hanging basket 1 and enters the sewer pipe; the accumulated water below the floor tile flows into the annular sand filtering groove 23 of the inner funnel 2 through the water filtering holes 16 on the sand filtering hanging basket 1, and after passing through the sand filtering holes 25, it is discharged from the bottom of the sand filtering hanging basket 1 through the hole in the lightweight annular rubber ring 4 and enters the sewer pipe. Since in the technical solution of the present invention, both the frustum section 13 and the second conical section 14 have no holes, the accumulated water above the floor tile will not enter below the floor tile. In addition, a lightweight annular rubber ring 4 is placed on the annular platform 15. The thickness of the lightweight annular rubber ring 4 is less than the height of the frustum section 13. The bottom of the frustum section 13 is larger than the top. The inner diameter of the top of the frustum section 13 is the same as the outer diameter of the lightweight annular rubber ring 4. The annular rubber ring 4 can be matched and covered with the bottom surface of the annular sand filtering groove 23 for sealing. Therefore, if the bottom of the sand filtering hanging basket 1 is blocked, the frustum section 13 will be filled with water. At this time, the lightweight annular rubber ring 4 will float to the top of the frustum section 13 under the action of water and be matched and covered with the bottom surface of the annular sand filtering groove 23 for sealing, blocking the sand filtering holes 25 to prevent the accumulated water from flowing back below the floor tile. At this time, the floor drain cover plate 3 can be taken out from the top cover 21, and the inside can be cleaned and dredged through the upper opening of the inner funnel 2; if the blockage is relatively serious, after the above-mentioned dredging and drainage, the clamping part of the top cover 21 and the sand filtering hanging basket 1 can be loosened, then the inner funnel 2 can be taken out from the sand filtering hanging basket 1, and then the lightweight annular rubber ring 4 can be taken out to deeply clean the blockage inside. After cleaning, the lightweight annular rubber ring 4 and the inner funnel 2 are placed in turn and tightened, and then the floor drain cover plate 3 is covered in the ring of the top cover 21 to complete the assembly and can be used continuously. Whether the floor drain of the present invention is in normal use or blocked, the accumulated water in the floor drain cannot flow below the floor tile.

[0031] A filter screen can also be placed in the annular sand filtering groove 23 to further filter the fine sand flowing out from below the floor tile. After using for a period of time, the inner funnel 2 can be taken out from the sand filtering hanging basket 1 to clean the inside of the annular sand filtering groove 23.

[0032] The lightweight annular rubber ring in the present invention can be a hollow rubber ring or a rubber ring made of lightweight material, and its density should be less than the density of water.

[0033] The annular rubber ring 4 can be matched and covered with the bottom surface of the annular sand filtering groove 23 for sealing in various ways. For example, a groove matching the annular rubber ring 4 is provided on the lower bottom surface of the annular sand filtering groove 23, so that the annular rubber ring 4 is embedded in the groove after floating up to be matched and sealed with the annular sand filtering groove 23; alternatively, the annular rubber ring 4 and the bottom surface of the annular sand filtering groove 23 can both be provided with convex and concave grooves that cooperate with each other, so that the two can be cooperatively sealed.

[0034] Embodiment 2

[0035] The floor drain in this embodiment further includes a self-sealing outlet assembly 5, as Figure 1 , 3 shown. Figure 7 is a cross-sectional view of the self-sealing outlet assembly, Figure 8 is a bottom view of the self-sealing outlet assembly. As Figure 7 , 8 shown; the self-sealing outlet assembly 5 includes a funnel 51, a hanging member 52, a water outlet cover plate 54 and a counterweight 55; the taper of the funnel 51 is the same as that of the second tapered section 14, and the funnel 51 is movably placed inside the outlet of the second tapered section 14; the lower part of the funnel 51 is tubular, and its end suspends the hanging member 52, and a rotating shaft 53 is arranged on the hanging member 52, and the water outlet cover plate 54 is fixed on the rotating shaft 53; one end of the water outlet cover plate 54 fixes the counterweight 55, and the other end can cover the outlet of the funnel 51.

[0036] In the floor drain of this embodiment, the self-sealing outlet assembly 5 is installed at the outlet of the second tapered section 14. When the floor drain is in a non-working state, that is, when there is no drainage to the sewer, under the action of the gravity of the counterweight 55, the water outlet cover plate 54 rotates around the rotating shaft 53 and covers the outlet of the funnel 51, preventing odor and insects such as cockroaches from entering the room through the water outlet. When the floor drain is in a working state, under the impact of water, the water outlet cover plate 54 rotates and opens for normal drainage.
