when many people choose toilet, they will encounter such a problem: which flush way is better, direct flush toilet or siphon toilet? The siphon type cleaning surface is large, and the direct impact type cleaning surface is large; The siphon type has low noise and the direct discharge type is clean. It’s hard to judge which one is better. The following will be a detailed comparison of the two, you can choose according to their own needs for their own one.
1、 Comparison of advantages and disadvantages between direct flush toilet and siphon toilet, The falling water power around the toilet circle is increased, and the flushing efficiency is high.
advantages: the flushing pipeline of direct flushing toilet is simple, the path is short, and the pipe diameter is thick (generally 9-10 cm). Using the gravity acceleration of water, the toilet can be flushed clean, and the flushing process is short. Compared with siphon type, direct flushing toilet has no return bend, so it is easy to flush large dirt, In the process of scouring, it is not easy to cause blockage, and there is no need to prepare a paper basket in the toilet. In terms of water saving, it is also better than the siphon toilet.
disadvantages: the biggest defect of the direct flush toilet is that the flushing sound is loud, and because the storage surface is small, it is easy to scale, and the anti odor function is not as good as the siphon toilet. In addition, the direct flush toilet has few varieties in the market at present, and the selection surface is not as big as the siphon toilet.
2 The structure of the siphon toilet is that the drainage pipe is in the shape of & lt; ∽” A certain water level difference will be produced when the drainage pipe is full of water, and the toilet will be discharged by the suction generated by the flushing water in the sewage pipe in the toilet. Because the flushing of the siphon toilet depends on the flow impulse, the water surface in the pool is larger and the flushing noise is smaller. Siphon toilet is also divided into vortex siphon and jet siphon.
vortex siphon
the flushing port of this kind of toilet is set at one side of the bottom of the toilet. When flushing, the water flows along the pool wall to form a vortex, which will increase the flushing force of the water flow on the pool wall and the suction of the siphon, which is more conducive to the discharge of the internal organs of the toilet.
spray siphon
is further improved on the siphon toilet. A spray auxiliary channel is added at the bottom of the toilet to align with the center of the sewage outlet. When flushing, part of the water flows out from the water distribution hole around the toilet ring, and part of the water flows out from the spray port. This kind of toilet is based on the siphon with the help of larger water flow impulse, Wash the dirt away quickly.
advantages: the biggest advantage of siphon toilet is that the flushing noise is small, which is called mute. In terms of flushing capacity, siphon type is easy to flush away the dirt adhering to the surface of the toilet, because siphon has higher water storage and better anti odor effect than direct flush type. Now there are many kinds of siphon type toilets on the market, so there will be more choices to buy one.
disadvantages: when the siphon toilet flushes, the water must be discharged to a very high level, and then the dirt can be flushed down. Therefore, a certain amount of water is required to achieve the purpose of flushing. It takes at least 8 to 9 liters of water each time, which is relatively expensive. Siphon type drainage pipe diameter is about 56 cm, easy to plug when flushing, so toilet paper can not be directly thrown in the toilet, installation of siphon type toilet generally also equipped with a basket and a carrier.
2、 Siphon PK flush toilet choose which flush scheme is better?
the siphon toilet is easy to flush the dirt adhering to the surface of the toilet, while the direct flush toilet is easy to flush the larger dirt due to the large diameter of the sewer pipe. Each of them has its own advantages and disadvantages, so we should take them into consideration. However, due to the focus of the topic of water saving, people have a new problem: under the premise of ensuring the momentum, is it direct or siphon water saving?
whether a toilet can save water depends on two aspects. One is the water tank? One is the bucket. Among them, the difference of the bucket part is the difference between direct flushing and siphon. Some European brands are represented by the direct flushing type, which adopts the British design standard. The characteristics are that the flushing pipeline is simple, the path is short, and the pipe diameter is thick. Generally, the diameter is between 90 cm and 100 cm. Using the gravity acceleration of water, it can easily clean the filth. The siphon pipe is very high, long and thin, because the smaller the pipe diameter is, the more obvious the siphon effect is, and the greater the pumping capacity is. But inevitably, the demand for water is greater. People who install siphon toilet in their homes will find that when flushing, the water must be discharged to a very high level, and then the dirt can go down with the water. Its design structure determines that it must have a certain amount of water. If you want to reach the level of flushing, you should use 8 or 9 liters of water at least once. If you force to reduce the flushing water to 3 / 6 liters, you will find that the flushing rate is not enough. Now some consumers in the market reflect that the 3 / 6-liter toilet is not clean, which is the reason. Toilet is to stress cooperation, if only use a water-saving water tank, but match is a large water storage bucket, it is difficult to achieve real water saving.
2 The water saving performance of
toilet depends on the coordinated design and installation of the whole flushing system. In the past, the reason why the flushing volume of the toilet can not be controlled is that the toilet is assembled in parts, and the water-saving performance of each part can not be coordinated. At present, there are few kinds of direct flush toilet in the market, and the performance of this kind of toilet is better than that of siphon type. Only at present, there are few such molds from domestic manufacturers, which leads to this situation in the market. Moreover, there is no return bend in the design of this kind of toilet, so it adopts direct flushing, which is not easy to cause blockage compared with siphon type in the process of flushing. The diameter of
siphon is about 56cm, which is about three times less than that of direct flush type. Therefore, it is very easy to block when flushing. Some people jokingly said that families with siphon toilets must have two pieces of supporting equipment: a paper basket and a carrier. Because if you throw toilet paper directly in the toilet, it’s easy to block it; And the aftermath of the work of nature can not do without a carrier.
3 Each has its own advantages and disadvantages. Recognize your own needs. The biggest advantage of siphon type is that it has low flushing noise, which is the so-called silent. The direct impact type uses the instantaneous strong kinetic energy of water flow, so the sound of impacting the pipe wall is not very pleasant. Most of the noise complaints about the toilet are aimed at this.
through market research, it is found that people are not particularly concerned about the noise of flushing, on the contrary, they are more concerned about the noise of water filling behind people, because it will last at least a few minutes. Some toilet water like a sharp whistle. The direct flush type can’t avoid the direct flush sound, but they emphasize the silence of water filling. What’s more, after going to the toilet, people hope that the shorter the flushing process is, the better. The direct flushing can have an immediate effect, and the siphon suspension process is also quite embarrassing. But the siphon type water seal is high, so it is not easy to taste.
in fact, no matter what kind of flush toilet you choose, there will be something to worry about and worry about. From the perspective of water saving alone, the direct flush toilet is definitely better than the direct flush toilet, but if there are quiet elderly people at home, you have to consider it. Although the siphon type is not perfect in the combination of water saving and flushing, its development in the domestic market has been very mature, and there is no peculiar smell. So you have to choose the best product according to local conditions.
4 In addition to the flush toilet, what to look at
look at the appearance: split toilet generally small volume, suitable for small space toilet; The integrated toilet has smooth lines, novel design, many styles to choose from, and the return bend of the bottom line of the toilet is closed, which provides convenience for future toilet cleaning; In addition, it is very important to observe the height of the toilet water tank. If the water tank is high, the impact is relatively large, and the flushing effect is relatively good.
look inside: in order to save cost, many toilet manufacturers work hard inside the toilet. There is no glaze in some return bends, and some use gaskets with low elasticity and poor sealing performance. This kind of toilet is not only easy to scale and block, but also easy to leak. Therefore, when you buy, you should reach into the dirty mouth of the toilet and touch whether it is smooth or not. Smooth hand is glazed, rough is not glazed. The gasket should be made of rubber or foamed plastic, with high elasticity and good sealing performance.
look at glaze: Toilet belongs to ceramic products, the glaze quality outside the ceramic is very important. The toilet with good glaze surface is smooth, meticulous and without defects. After repeated washing, it can still be as smooth as new. If the glaze quality is not good, it is easy to make the dirt hanging on the four walls of the toilet.
after sales: Generally speaking, sanitary ware sellers in the market have relatively reliable and complete after-sales service. Buyers can enjoy free installation, 3 to 5 years of warranty service. During this period, the manufacturer is responsible for free maintenance and replacement. Even after the warranty period, only the cost is charged for replacement. However, some small-scale sellers can not provide after-sales service even though they promise warranty.
