[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figures 1 to 5 This utility model proposes an easy-to-clean floor drain, including a base, a drain body, and a cover plate 3. The base includes an outer shell 4, an inner shell 5, and a connecting plate 6. The outer shell 4 has a square structure, and the inner shell 5 has a circular structure. The inner shell 5 is fixedly connected to the outer shell 4 through the connecting plate 6. The upper end of the inner shell 5 is lower than the upper end of the outer shell 4. The upper side of the connecting plate 6 is provided with a guide surface 7 for guiding water flow to the inner shell 5. Four guide surfaces 7 are provided, respectively located at the four corners of the outer shell 4. The cover plate 3 is square and fits the outer shell 4. The cover plate 3 is installed on the upper side of the outer shell 4 and has a water inlet 12. The drain body includes a cup 16 and guide ribs. The cup is set in the inner shell 5. The upper end of the cup is circular and fits the inner shell 5. The inner shell 5 supports the upper end of the cup. Figure 5,The inner wall of the cup body is substantially a conical surface that is larger at the top and smaller at the bottom, the inclination angle between the inner wall of the cup body and the horizontal plane is a, 50°<a<80°, the inner wall of the cup body is steep from a position close to the upper edge to a position close to the cup bottom, the inner wall of the cup body is more vertical, and water drains faster. A plurality of main drain outlets 8 are arranged at the bottom of the cup body, and the main drain outlets 8 are arranged around the circumferential direction of the cup bottom. A plurality of flow guide ribs are provided, specifically 4, which are arranged in an annular array inside the cup body, and a water inlet channel 9 is formed between every two adjacent flow guide ribs, forming 4 water inlet channels 9 in total. Each flow guide rib includes a main flow guide part 10, which starts from the upper edge of the cup body, extends toward the center of the cup body and simultaneously extends in the clockwise direction. When the water flow passes through the main flow guide part 10, a tangential component force is generated, which promotes the water flow to form a vortex. The height of the cup body is h1, the distance between the inner end of the main flow guide part 10 and the bottom of the cup body is h2, 1 / 3<h2 / h1<1 / 2, that is, 1 / 3*h1<h2<1 / 2*h1. When h2>1 / 3*h1, the effect of generating a vortex is obvious, and when h2<1 / 2*h1, there is sufficient space at the cup bottom to generate a vortex.

[0019] The working principle of the floor drain is as follows: the base is pre-embedded in the ground, the upper side of the cover plate 3 is flush with the ground, the accumulated water on the ground falls onto the flow guide surface 7 through the water inlet 12, and the flow guide surface 7 guides the water flow to the main flow guide part 10 of the flow guide rib. After being guided by the main flow guide part 10, the water flow spirals down along the inner wall of the cup body to form a vortex at the cup bottom. The hairs in the water flow quickly clump together under the rotation, the water flow is discharged downward through the main drain outlet 8, and the clumped hairs have an increased volume, which is not easy to block the main drain outlet 8 and not easy to hang on the inner wall of the cup body. When cleaning the hairs, the cover plate 3 is removed, and the clumped hairs can be quickly taken out from the cup body, achieving the purpose of quick cleaning.

[0020] In one embodiment, such as Figure 3 , the flow guide rib further includes a secondary flow guide part 11, which is arranged on the inner side of the main flow guide part 10. The secondary flow guide part 11 starts from the outer end of the main flow guide part 10, extends toward the center of the cup body and simultaneously extends in the clockwise direction. The inner end of the secondary flow guide part 11 is flush with the inner end of the main flow guide part 10, and a secondary drain outlet 13 is arranged on the cup body between the main flow guide part 10 and the secondary flow guide part 11. For the water flow rotating clockwise in the cup body, when the water level in the cup body is relatively high, the secondary flow guide part 11 can further guide the water flow, reduce the contact of the water flow with the secondary drain outlet 13, thereby preventing the hairs in the water flow from hanging on the secondary drain outlet 13. The secondary drain outlet 13 is only used as a standby drain outlet when the main drain outlet 8 is accidentally blocked, preventing the water in the floor drain from flowing back to the ground.

[0021] In one embodiment, the water inlets 12 are arranged at the edge of the cover plate 3, specifically concentrated at the four corners of the cover plate 3. The water inlets 12 are arranged above the flow guide surface 7, so that most of the accumulated water on the ground is discharged to the floor drain main body through the flow guide surface 7, and the effect of forming a vortex is obvious.

[0022] In one embodiment, the outlet end of the guide surface 7 faces the inlet channel 9.

[0023] In one embodiment, such as Figure 1 A secondary water inlet 15 is provided at the center of the cover plate 3. The cross-sectional area of ​​the secondary water inlet 15 is smaller than that of the water inlet 12. When there is little water on the ground, the water on the ground mainly enters the drain from the water inlet 12 at the edge of the cover plate 3. When there is a lot of water on the ground, the secondary water inlet 15 helps to drain the water. The secondary water inlet 15 is located above the bottom of the cup and has a small opening. The water flowing from the secondary water inlet 15 is located at the center of the vortex and does not affect the formation of the vortex.

[0024] In one embodiment, the upper end of the cup body is provided with an outwardly extending support edge 14, which rests on the upper end of the inner shell 5.

[0025] In one embodiment, the distance between the guide rib and the cover plate 3 is h3, where h3 < 5mm. By bringing the guide rib close to the cover plate 3, the water flowing into the drain from the inlet 12 can spiral downwards under the action of the guide rib.

[0026] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
