Description

Technical Field

[0001] The invention relates to a floor drain. Background Art

[0002] The existing floor drain generally includes a floor drain body and a hydrophobic cover plate. The floor drain body is provided with a sunken cavity, the top of the cavity forms an opening, the bottom wall of the cavity is provided with a through hole, the shape of the hydrophobic cover plate matches the opening so that it can just cover the opening, and the top surface of the hydrophobic cover plate is provided with a plurality of water holes arranged at intervals. The existing floor drain generally has the following two points that need to be improved: 1. The water discharge speed is slow; 2. It is inconvenient to clean impurities such as hair attached to the hydrophobic cover plate. Summary of the invention

[0003] One of the purposes of the present invention is to provide a floor drain which can greatly increase the drainage speed and has a very simple structure;

[0004] The second object of the present invention is to provide a floor drain which can more conveniently clean impurities such as hair attached to the hydrophobic cover plate;

[0005] To achieve the above object, the present invention provides the following technical solution: a floor drain, comprising:

[0006] The floor drain body is provided with a sunken cavity, the top of the cavity is open, and the middle of the bottom wall of the cavity is provided with a through hole;

[0007] A hydrophobic cover plate, comprising a top cover and a grille longitudinally connected to the periphery of the top cover, wherein the grille comprises a plurality of spaced retaining ribs, the hydrophobic cover plate is installed in the concave cavity, and a flow gap is formed between the periphery of the top cover and the side wall of the concave cavity;

[0008] The movable part is movably arranged on the hydrophobic cover plate to push the impurities attached to the retaining rib away from the retaining rib.

[0009] According to the floor drain of the present invention, since its hydrophobic cover plate includes a top cover and a grille longitudinally connected to the periphery of the top cover, the grille includes a plurality of spaced retaining ribs, and a flow gap is formed between the periphery of the top cover and the side wall of the concave cavity, so that the water flow is not directly drained from the top cover, but bypasses the longitudinally arranged grille through the flow gap for drainage. On the one hand, the longitudinal arrangement of the grille can make the water flow area larger, which is conducive to improving the drainage speed; on the other hand, the top cover plays a role in blocking the contact between the air and the center of the water vortex in the floor drain body, so that it is easier to form a siphon when the floor drain is drained, thereby accelerating the drainage speed. In addition, the floor drain of the present invention is more convenient to use by arranging a movable part on the hydrophobic cover plate for cleaning impurities such as hair attached to the hydrophobic cover plate.

[0010] Preferably, the top cover is flush with the top surface of the floor drain body.

[0014] In the above scheme, a movable part with a convex portion is provided, and the convex portion is located in the gap between adjacent retaining ribs of the grille. In this way, as long as the movable part is driven, the convex portion can push the impurities attached to the retaining ribs away from the retaining ribs, thereby effectively solving the problem of inconvenient cleaning of impurities such as hair attached to the hydrophobic cover plate in the floor drain of the prior art, and the structure is simple.

The floor drain body 10 is provided with a sunken cavity 11, the top of the cavity 11 is open, and a through hole is provided in the middle of the bottom wall of the cavity 11. The hydrophobic cover plate 20 comprises a top cover 21 and a grille 22 longitudinally connected to the periphery of the top cover 21, the grille 22 comprises a plurality of spaced retaining ribs 221, the hydrophobic cover plate 20 is installed in the cavity 11, and a flow gap A is formed between the periphery of the top cover 21 and the side wall of the cavity 11. The movable part 30 can be movably arranged on the hydrophobic cover plate 20 up and down to push impurities attached to the retaining rib 221 away from the retaining rib 221.

[0043] According to the floor drain of the present invention, since its hydrophobic cover plate 20 includes a top cover 21 and a grille 22 longitudinally connected to the periphery of the top cover 21, the grille 22 includes a plurality of spaced retaining ribs 221, and a flow gap A is formed between the periphery of the top cover 21 and the side wall of the concave cavity 11, so that the water flow is not directly drained from the top cover 21, but is drained around the longitudinally arranged grille 22 through the flow gap A. On the one hand, the longitudinal arrangement of the grille 22 can make the water flow area larger, which is conducive to improving the water discharge speed; on the other hand, the top cover 21 plays a role in blocking the contact between the air and the center of the water flow vortex in the floor drain body 10, so that it is easier to form a siphon when the floor drain is discharged, thereby accelerating the water discharge speed. In addition, the floor drain of the present invention is also more convenient to use by arranging a movable part 30 on the hydrophobic cover plate 20 for cleaning impurities such as hair attached to the hydrophobic cover plate 20.

By providing the movable member 30 with the convex portions 32, the convex portions 32 are located in the gaps between adjacent retaining ribs 221 of the grille 22, so that as long as the movable member 30 is driven, the convex portions 32 can effectively push the impurities attached to the retaining ribs 221 away from the retaining ribs 221.

In this embodiment, the inner wall of the through hole is provided with an internal thread, and the outer wall of the flow tube 61 is provided with an external thread, and the flow tube 61 is threadedly fixedly connected to the through hole.

[0054] When assembling, Figure 1 and Figure 2 As shown, first, the flow pipe 61 is threadedly fixedly connected to the through hole of the floor drain body 10; then, the hydrophobic cover plate 20, the movable part 30, the button 40 and the second elastic part 50 are assembled into an integral component; finally, the integral component assembled by the hydrophobic cover plate 20, the movable part 30, the button 40 and the second elastic part 50 is placed in the concave cavity 11 of the floor drain body 10. When draining, the water flows from the flow gap A to the grille 22, and enters the flow pipe 61 after passing through the grille 22 to block impurities. Under the action of the water flow pressure, the sealing plate 62 opens the bottom end opening of the flow pipe 61, thereby completing the rapid draining.

[0055] When there are many impurities attached to the retaining ribs 221 of the grille 22, the integral assembly composed of the hydrophobic cover plate 20, the movable member 30, the button 40 and the second elastic member 50 is directly taken out from the concave cavity 11 of the floor drain body 10 (such as Figure 3Then, follow Figure 4 Press the button 40 in the direction of the arrow F shown, and the button 40 drives the movable part 30 to move relative to the hydrophobic cover plate 20.
