How to optimize the drainage design of Shower Tray to prevent water accumulation?

To optimize the drainage design of the Shower Tray to prevent water accumulation, we can start from the following key aspects:

Chassis surface slope design
1.1 Determine a reasonable slope
Standard slope: The slope of the chassis surface is generally between 1-2%, which is ideal for fast drainage and standing comfort.
Multi-directional slope: The multi-slope design allows water to flow from all directions to the drain outlet, avoiding water accumulation areas caused by a single slope.
1.2 Slope uniformity
Automated processing: Use precision molds or CNC equipment to ensure uniform slope distribution and avoid local depressions that cause water accumulation.
Surface inspection: Perform optical inspection during the production process to confirm that the surface slope meets the design standards.
Drain outlet position and shape optimization
2.1 Drain outlet position
Central drain outlet: Placed in the center of the chassis, it is conducive to uniform convergence of water flow, but it is necessary to ensure that the slopes on all sides are consistent.
Offset drain outlet: According to user needs and space limitations, the drain outlet is designed on one side or in a corner, and the slope is adjusted accordingly to guide the water flow.
2.2 Drain shape
Circular drain: suitable for traditional design, easy to install, and high drainage efficiency.
Strip drain: suitable for modern minimalist style, can increase drainage speed, and avoid drainage blocked by hair and debris.
Invisible drain: hide the drain in the design, beautiful and generous, but ensure smooth drainage.

Drainage system improvement
3.1 Improve drainage smoothness

Drainage pipe diameter optimization: choose a larger diameter drainage pipe (such as 50-75mm) to avoid water blockage.
Smooth water flow design: try to avoid right-angle design of pipe interface, and use arc or inclined structure to reduce flow resistance.
3.2 Anti-blocking function
Filter device: install a detachable filter at the drain outlet to effectively intercept hair and debris for easy cleaning.
Deodorant chip: use silicone sealing core or other deodorant device to avoid odor from the sewer pipe and keep drainage smooth.

Prevent reflux and airflow interference
4.1 Drainage reflux
Siphon design: prevent water in the pipe from flowing back to the chassis through water seal or siphon structure.
Fine adjustment of slope: Ensure that the chassis slope can overcome the water accumulation problem caused by backflow.
4.2 Air flow interference
Vent design: Add a vent to the drainage system to balance the air pressure generated during drainage and prevent negative pressure from affecting drainage efficiency.

Material and surface treatment
5.1 Surface material selection
Hydrophobic material: Select materials with hydrophobic properties, such as nano-coatings or polymer composites, to reduce water retention.
5.2 Surface texture
Smooth surface: The chassis surface should be as smooth as possible to reduce water friction resistance.
Microgroove texture: Microgroove texture is designed through laser or mold technology to guide water flow to the drain.

Installation and maintenance optimization
6.1 Installation angle
During the installation process, ensure that the chassis is installed at the designed angle, such as using a level to confirm that the overall slope of the chassis meets the design requirements.
6.2 Cleaning and maintenance
Regularly clean the drain and pipes to avoid dirt accumulation and poor drainage.

By rationally designing the slope, optimizing the position and shape of the drain outlet, improving the drainage system structure, and enhancing installation accuracy and daily maintenance, the problem of water accumulation in the shower tray can be effectively solved, while improving the user experience and product performance.
