Here’s our guide to the essential appliances for a cozy summer home.

In our daily life, we often see some washbasins without traditional air vents in the toilet. They stand quietly, but can quickly drain away the sewage, and don't let the smell spread. It makes you wonder how these sinks manage to drain and deodorize so efficiently without the help of vents? Let's take a look at the world of ventless sinks and see how they work.

1.Siphon principle

The siphon principle is the key to efficient drainage of ventless sinks. In a nutshell, siphonage is the flow of liquid from a height down a curved pipe under the combined action of gravity and atmospheric pressure. In an unventilated sink, when the water level in the sink reaches a certain height, the flow of water quickly fills the drain and forms a continuous column of water. At this point, the air pressure in the pipeline and the external atmospheric pressure difference, the external atmospheric pressure will be the water column pressure to the drain, which produces a strong suction, the sewage discharged quickly. This physics-based method of drainage is like a powerful engine, providing a constant stream of power to drain the sink.

2.Design of drainage pipeline

The design of drainage pipeline is an important guarantee for the efficient drainage of the sink without vents. It is not a simple straight line, but a complex network with careful planning and design. The bends and slopes of the pipes are accurately calculated to ensure smooth passage of water and to prevent backflow of sewage. For example, a drainage pipe will usually set a certain slope, using gravity to make the flow of water down the natural flow. At the same time, the bend of the pipe will use a special radian design to reduce water flow resistance and avoid water accumulation or blockage. This clever arrangement acts like a highly efficient transportation network, allowing sewage to flow out quickly and in an orderly fashion.

3.Water flow control

Water flow control is an important part of the normal operation of a sink without vents. As the entrance of water into the sink, the size of the tap switch directly affects the flow and speed of water. Reasonable control of the tap switch can make the water flow into the sink at an appropriate speed, which will neither splash out of the sink due to excessive flow, nor affect the use effect due to too small flow. In addition, the outlet valve also plays a vital role. It can be according to the pool water level and drainage needs, timely opening or closing, to ensure the orderly drainage process. When the water level in the pool reaches a certain height, the valve opens automatically and the sewage is discharged quickly. When the water level drops to a certain degree, the valve closes automatically to prevent the backflow of odor.

4.Sealing and odor control

For a sink without vents, sealing and odor-proof design are key to preventing odors from emanating. The joint between the drain and the sink is sealed with high-quality rubber rings to ensure that no sewage or odor leaks. At the same time, the drainage pipe is also provided with a water storage bend. Water Storage Bend has always maintained a certain height inside the water seal, like a natural barrier, the drainage pipe odor firmly blocked. The existence of water seal makes use of the water tightness, which makes the odor in the pipeline unable to enter the room through the drain, thus keeping the air fresh in the toilet.

Conclusion

With its unique siphon principle, ingenious drainage pipe design, precise water flow control, strict sealing and deodorization measures, as well as daily maintenance and maintenance, the ventless washbasin, has become in the toilet the highly effective drainage and the anti-stink skillful craftsman. It not only brings convenience to our life, but also improves the overall environmental quality of the toilet. Understanding how it works can help us use and maintain it better, and keep it in service to our lives.
