Many people will encounter this problem when purchasing a toilet: which flushing method is better, direct flush or siphon type? The siphon type has a large cleaning surface, and the direct flush type has a large impact; the siphon type has low noise, and the direct flush type has clean sewage discharge. The two are equally matched, and it is difficult to judge which one is better. Below, the editor will make a detailed comparison between the two, so that you can choose the one that suits you according to your needs.

1. Comparison of the advantages and disadvantages of direct flush type and siphon type toilet flush

1. Direct flush type Water Closet

Direct-flush toilets use the momentum of water flow to discharge feces. Generally, the pool walls are steep and the water storage area is small. In this way, the water power is concentrated, and the falling water power around the toilet ring is increased, and the flushing efficiency is high.

Advantages: Direct-flush toilets have simple flushing pipelines, short paths, and thick pipe diameters (generally 9 to 10 cm in diameter). The gravity acceleration of water can be used to flush the feces clean. The flushing process is short, and it is similar to the siphon toilet. In terms of flushing capacity, direct flush toilets do not have a return deflector and can flush larger dirt easily, making it less likely to cause blockage during the flushing process. There is no need to prepare a paper basket in the bathroom. In terms of water saving, it is also better than the siphon toilet.

Disadvantages: The biggest disadvantage of direct flush toilets is that the flushing sound is loud, and because the water surface is small, scaling is prone to occur, and the anti-odor function is not as good as that of siphon toilets. In addition, direct flush toilets are currently on the market. There are relatively few varieties on the market, and the choice is not as large as that of siphon toilets.

2. Siphon type

The structure of the siphon Inodoro toilet is that the drainage pipe is in the shape of a "∽". When the drainage pipe is filled with water, a certain water level difference will occur. The suction generated by the flushing water in the drain pipe in the toilet will drain the feces away. Since the siphon toilet Flushing does not rely on the momentum of water flow, so the water surface in the pool is larger and the flushing noise is smaller. Siphon toilets are also divided into two types: vortex siphon and jet siphon.

Vortex siphon

The flushing port of this kind of toilet is located on one side of the bottom of the toilet. When flushing, the water flow forms a vortex along the pool wall. This will increase the flushing force of the water flow on the pool wall, and also increase the suction force of the siphon effect, which is more conducive to flushing the toilet. Internal organs are discharged.

Further improvements have been made to the siphon toilet. A secondary jet channel is added to the bottom of the toilet, aiming at the center of the sewage outlet. When flushing, part of the water flows out from the water distribution holes around the toilet seat, and part of it is sprayed out from the jet port. , this kind of toilet uses a large water flow momentum based on siphon to quickly flush away dirt.

Advantages: The biggest advantage of the siphon toilet is that it makes less flushing noise, which is called silent. In terms of flushing ability, the siphon type can easily flush away the dirt adhered to the surface of the toilet. Because the siphon has a higher water storage capacity, the anti-odor effect is better than that of the direct flush type. Nowadays, there are many varieties of siphon toilets on the market. It is difficult to buy a toilet. There are more options.

Disadvantages: When flushing, the siphon toilet must first release water to a very high water level, and then flush the dirt down. Therefore, a certain amount of water is required to achieve the purpose of flushing. At least 8 liters to 9 liters of water must be used each time. Relatively speaking, it is relatively wasteful. The diameter of the siphon drainage pipe is only about 56 centimeters, and it is easy to get clogged when flushing, so toilet paper cannot be thrown directly into the toilet. Installing a siphon toilet usually requires a paper basket and a spatula.
