The working principle of the bathroom floor drain is mainly based on the principle of water sealing and mechanical principles to prevent odors and sewage backfilling.
Water sealing principle: The floor drain forms a water seal by storing a certain amount of water, which can effectively prevent the smell of the sewer and the possible backflow of sewage into the room. The height of the water seal usually needs to meet certain standards, such as the water seal height required by the national standard is 50mm to ensure the anti-odor effect.
Mechanical principle: In addition to water sealing, some floor drains also use mechanical devices, such as eccentric floor drains use the principle of gravity to seal, and spring-type floor drains are sealed by the elastic force of springs, and these mechanical parts help to enhance the anti-odor and drainage functions of floor drains.
Modern intelligent floor drains: With the development of technology, intelligent floor drains have appeared, which regularly add water to the floor drain through the controller to keep the water seal moist and prevent it from drying out, and at the same time automatically clean the floor drain to reduce clogging and odor problems.
These principles ensure that floor drains not only drain water efficiently, but also prevent odors and back-up of wastewater, keeping the bathroom environment clean and hygienic.
