Description

Drainage structure of invisible floor drain Technical Field The utility model relates to the technical field of drainage, in particular to a drainage structure of an invisible floor drain. Background The prior floor drain structure generally adopts an open-type design, the drain pipe and the cover plate of the prior floor drain are exposed on the ground or the wall surface, and the technical pain is that the cover plate and the drain outlet of the open-type floor drain are required to be protruded or embedded into decorative surfaces (such as floor tiles and wall bricks), so that obvious chromatic aberration, height difference or wide seam exist between the cover plate and the peripheral plane, the space integrity is destroyed, the metal cover plate of the prior floor drain is difficult to match with the texture of the decorative surfaces, the design is compromised or a complex edging process is forced to be adopted, the drain pipe is usually designed with a small pipe diameter (such as DN40 or below) so as to cause the drain flow to be limited, the drain pipe is easy to be blocked by hairs and dirt, frequent cleaning is required, and the size of the cover plate is increased when the pipe diameter is increased, and the aesthetic property is further aggravated. In the bathroom shower scene, the drainage caliber of the traditional floor drain is too small and the structure is complex, hair and fabrics are easy to hang upside down and block, water accumulation is slowly caused by drainage, potential safety hazards exist, and cleaning and maintenance are difficult. Disclosure of utility model The utility model aims to provide a drainage structure of an invisible floor drain, which can alleviate the problems. In order to alleviate the problems, the technical scheme adopted by the utility model is as follows: The utility model provides a drainage structure of an invisible floor drain, which comprises an overhead layer, a sewer pipe, floor tiles and wall tiles, wherein the overhead layer is provided with a drainage groove assembly from top to bottom, a drainage gap leading to a drainage groove of the drainage groove assembly is arranged between the floor tile and the wall tiles, and the drainage groove assembly comprises a structural part which is in interference fit with each other and forms the drainage groove, and a drain pipe which is arranged in a water outlet hole of the drainage groove and is inserted into the sewer pipe. In a preferred embodiment of the present utility model, the drainage channels are provided with a plurality of bridges for supporting the floor tile. In a preferred embodiment of the present utility model, the structural member includes an intermediate structural groove member, a left segment structural groove member and a right segment structural groove member respectively connected to left and right ends of the intermediate structural groove member in an interference fit manner, a left end groove port plugging groove member connected to left end of the left segment structural groove member in an interference fit manner, and a right end groove port plugging groove member connected to right end of the right segment structural groove member in an interference fit manner, wherein the water outlet hole is opened in the intermediate structural groove member. In a preferred embodiment of the utility model, the drain pipe is provided with a supporting platform, and the drain pipe is inserted into the water outlet hole and is supported at the bottom of the middle structure groove piece by the supporting platform. In a preferred embodiment of the present utility model, each interference portion of the drain tank assembly is provided with a rubber gasket. Compared with the prior art, the utility model has the beneficial effects that: 1) The drainage tank component is embedded into the overhead layer, only a drainage gap is reserved between the floor tile and the wall tile, the traditional floor drain cover plate is completely hidden, the floor drain cover plate is visually and seamlessly fused with the decorative surface, and the space design freedom degree and high-end texture are improved. 2) The multi-section structural member is in interference fit to form a continuous drainage groove, so that each component is convenient to install and transport; 3) The drain pipe of the surface floor drain is usually limited by a small pipe diameter design, is easy to block and has weak pollution discharge capacity, the drain pipe is hidden in the drain tank in the structure, and can adapt to different scene demands (such as a terrace DN110 pipe diameter and a shower room DN75 pipe diameter), so that the drain flow is obviously promoted, meanwhile, the ponding drainage is accelerated through a siphon effect, and the problems of terrace rainwater backflow and shower room hair blocking are effectively solved; 4) The drainage tank assembly is assembled by adopting standardized structural members, and is suitable
