Description

Technical Field

[0001] This utility model relates to the field of drainage technology, and more specifically, to a drainage structure for an invisible floor drain. Background Technology

[0002] Traditional floor drains generally adopt an exposed design, with their drain pipes and covers exposed on the floor or wall. This presents the following technical challenges: The cover and drain outlet of an exposed floor drain need to protrude from or be embedded in the decorative surface (such as floor tiles or wall tiles), resulting in obvious color differences, height differences, or wide gaps with the surrounding surface, which disrupts the overall spatial integrity. Especially in minimalist styles or slab-paved scenarios, the metal cover of a traditional floor drain is difficult to match the texture of the decorative surface, forcing design compromises or the use of complex edge finishing techniques. To reduce the visual presence of exposed floor drains, their drain pipes are usually designed with small diameters (such as DN40 or below), resulting in limited drainage flow and easy clogging by hair and dirt, requiring frequent cleaning. Increasing the pipe diameter, on the other hand, would increase the size of the cover, further exacerbating the deterioration of aesthetics. In terrace applications, traditional gutter drains and floor drains are easily clogged by fallen leaves and flowers, leading to poor rainwater drainage and backflow. In bathroom shower applications, traditional floor drains have too small a diameter and complex structure, making them prone to being blocked by hair and fabrics. This results in slow drainage, water accumulation, safety hazards, and difficulty in cleaning and maintenance. Utility Model Content

[0003] The present invention provides a drainage structure for an invisible floor drain, which can alleviate the above-mentioned problems.

[0004] To alleviate the above problems, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a drainage structure for an invisible floor drain, including a raised layer, a drain pipe, floor tiles, and wall tiles. A drainage channel assembly is installed in the raised layer from top to bottom. A drainage gap is provided between the floor tiles and wall tiles to lead to the drainage channel assembly. The drainage channel assembly includes a plurality of structural members that are interference-fitted to form the drainage channel, and a drain pipe installed in the drainage channel and inserted into the drain pipe.

[0006] In a preferred embodiment of this utility model, the drainage channel is provided with several bridges for supporting the floor tiles.

[0007] In a preferred embodiment of this utility model, the structural component includes a middle structural groove, a left section structural groove and a right section structural groove respectively interference-fitted to the left and right ends of the middle structural groove, an interference-fitted left end slot sealing groove for the left end of the left section structural groove, and an interference-fitted right end slot sealing groove for the right end of the right section structural groove; the water outlet is formed in the middle structural groove.

[0008] In a preferred embodiment of this utility model, the drain pipe is provided with a support platform, the drain pipe is inserted into the water outlet hole, and is positioned by being supported by the support platform on the bottom surface of the intermediate structural trough.

[0009] In a preferred embodiment of the present invention, each interference fit of the drainage channel assembly is provided with a rubber sealing gasket.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1) The drainage channel component is embedded in the raised floor, leaving only gaps between the floor tiles and wall tiles for drainage, completely hiding the traditional floor drain cover. Visually, it blends seamlessly with the decorative surface, enhancing the freedom of space design and the high-end feel.

[0012] 2) The multi-segment structural components are interference-fitted to form a continuous drainage channel, which facilitates the installation and transportation of each component;

[0013] 3) Exposed floor drains are usually limited by small pipe diameter design, making them prone to clogging and with weak sewage discharge capacity. In this structure, the drain pipe is hidden in the drainage channel, which can be adapted to different scenario needs (such as DN110 pipe diameter for terraces and DN75 pipe diameter for shower rooms), significantly improving drainage flow. At the same time, the siphon effect accelerates the pumping out of accumulated water, effectively solving the problems of rainwater backflow on terraces and hair clogging in shower rooms.

[0014] 4) The drainage channel assembly adopts standardized structural components to meet the needs of different specifications of floor drains. During construction, it is only necessary to reserve an installation position in the elevated floor and insert the drainage pipe, without the need for complicated pre-embedding procedures.

[0015] 5) In terrace applications, the continuous drain outlet combined with the slope design expands the drainage coverage and reduces water accumulation on the decoration; in shower rooms, the extended drain outlet and optimized water trap curvature can guide hair and debris into the main riser with the water flow, reducing maintenance frequency.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] Please refer to Figures 1-4 This embodiment provides a drainage structure for an invisible floor drain, including a raised layer 4, a drain pipe 5, floor tiles 3 and wall tiles 2. A drainage channel assembly 8 is installed in the raised layer 4 from top to bottom. A drainage gap 6 is provided between the floor tiles 3 and the wall tiles 2 to lead to the drainage channel assembly 8. The drainage channel assembly 8 includes a number of structural members that are interference-fitted to form a drainage channel, and a drain pipe 81 installed in the drainage channel with an outlet hole 821 and inserted into the drain pipe 5.

[0025] In this embodiment, all components of the drainage channel assembly 8 are made of PVC material. The resulting sunken drainage channel enables concealed drainage. Two implementation methods are provided for different application scenarios: a 110mm diameter pipe channel and assembly are used for terrace drainage, and a 75mm diameter pipe channel and assembly are used for bathroom shower room drainage. The drainage channel assembly 8 is embedded in the raised floor 4, and the drainage gap 6 between the floor tile 3 and the wall tile 2 is used as a concealed drainage channel, replacing the traditional exposed floor drain cover. At the same time, the drainage channel is formed by interference fit of split structural components, and directly connected to the drain pipe 5 by a large-diameter drain pipe 81.

[0026] In terrace applications, the full-length decorative drain design increases the drain diameter, and the 4-degree slope of the raised floor guides rainwater to flow quickly and achieves instantaneous drainage through a siphon. In shower room applications, the extended drain design accelerates water flow and, combined with the siphon effect generated by the drop in the sink drain, can flush hair in the trap into the main riser.

[0027] In an optional embodiment of this utility model, the drainage channel is provided with several cable trays 7 for supporting the floor tiles 3. The cable trays 7 serve as supporting bases for the floor tiles 3, which can evenly distribute the load on the floor tiles 3 and prevent the drainage channel from being deformed by pressure.

[0028] In an optional embodiment of this utility model, the structural component includes a central structural groove 82, a left structural groove 83 and a right structural groove 85 respectively connected to the left and right ends of the central structural groove 82 by interference fit, a left end groove sealing groove 84 connected to the left end of the left structural groove 83 by interference fit, and a right end groove sealing groove 86 connected to the right end of the right structural groove 85 by interference fit; a water outlet 821 is formed in the central structural groove 82. The split structural component allows for adjustment of the lengths of the left and right sections according to the wall spacing to adapt to different shower area sizes. The water outlet 821, located in the central groove, guides water flow towards the center for rapid discharge, preventing localized water accumulation within the groove.

[0029] In an optional embodiment of this utility model, the drain pipe 81 is provided with a support platform 811, the drain pipe 81 is inserted into the water outlet 821, and is positioned by being supported by the support platform 811 on the bottom surface of the intermediate structural groove 82. When installing the drain pipe 81, it can be directly placed into the water outlet 821, which is very convenient.

[0030] In an optional embodiment of this utility model, each interference fit of the drainage groove assembly 8 is provided with a rubber sealing gasket. This design is optional. If the interference fit can completely achieve a seal, the sealing gasket is not required.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
