Contrast the advantages and disadvantages of direct and siphon
1, direct impact type
Direct flush toilet is the exercise of water impulse to squeeze out poop, as usual pool wall is steeper, water storage area is smaller, so that the hydraulic concentration, then the ring around the falling hydraulic increase, high flushing efficiency.
Advantages: Direct flushing toilet is simple, short path, thick pipe diameter (the usual diameter of 9 to 10 cm), exercise the gravity acceleration rate of water can wash the poop clean, short flushing process, compared with the siphon from the flushing capacity, direct flushing toilet has no water back bend to accept direct flushing, easy to wash down the larger dirt, not easy to cause blockage in the scouring process. No wastepaper baskets in the bathroom. In terms of water saving, it is also better than siphon toilets.
Defects: The biggest defect of direct flushing toilet is the loud flushing sound, due to the small water surface, easy to scale signs, deodorant effect is not as good as siphon toilet, in addition, direct flushing toilet is now on the market varieties control less, the choice surface is not as big as siphon toilet.
2. Siphon type
Siphon toilet structure is the drainage pipe was “∽” type, after the drainage pipe filled with water will produce a certain water level difference, by flushing water in the toilet sewage pipe suction will drain away, because siphon toilet flushing is not with the water momentum, so that the pool memory water surface is larger, Flushing noise is smaller siphon type toilet is also divided into vortex siphon, jet siphon two.
Vortex siphon
The toilet flushing outlet is located at the bottom of the toilet. When flushing, the water flows along the wall of the pool to form a vortex, which will increase the flushing force of the flood flow on the wall of the pool, but also increase the suction of the siphon effect, which is more conducive to the displacement of the toilet viscera instruments.
Jet siphon
In the siphon type toilet to do a further improvement, in the bottom of the toilet to add a jet deputy, aiming at the center of the sewage outlet, flushing, a department of water from the cloth hole around the ring outflow, a department by the jet mouth, this kind of toilet is on the basis of the siphon with the larger water impulse, the dirt quickly washed away.
Advantage: The biggest advantage of siphon type toilet is low flushing noise, called silent. From the flushing capacity, the siphon type is easy to wash away the dirt attached to the outside of the toilet, because the siphon water storage is higher, the anti-odor effect is better than the direct flushing type, now on the market siphon type toilet varieties, buy toilet will have more room for choice.
Defects: siphon type toilet flushes first to release water to a very high surface, and then the dirt flushes down, in order to have a certain amount of water to reach the purpose of flushing, each time at least 8 to 9 liters of water, relative to the cost of water. Siphon drainage pipe diameter is about 56 cm, easy to block when flushing, so that toilet paper can not be directly thrown in the toilet, installation of siphon toilet as usual but also equipped with paper baskets and plungers.
Two, siphon PK flush toilet choose what kind of flushing plan compare well?
The siphon toilet is easy to flush away the dirt attached to the outside of the toilet, while the straight flush toilet has a large diameter of the sewer pipe, which is easy to flush down the larger dirt. They all have advantages and disadvantages, so you should consider them comprehensively when buying.
1. Pursue a balance between water saving and flushing rate
However, due to the focus of the topic of water saving, people have a new problem: under the condition of ensuring the momentum of the direct impact or siphon water saving?
Whether a toilet is water-saving depends on two aspects, one is the tank? One is sitting in a bucket. The difference in the bucket sector is the difference between straight and siphon. Some European brands are represented by the direct flushing type, accept the British design scale, is characterized by simple flushing pipe road, short path, and the diameter of the pipe is thick, the usual diameter of 90 to 100 cm, exercise the gravity acceleration rate of water can easily wash dirty things clean. And the siphon pipe goes very high, long and thin, because the smaller the diameter of the pipe, the siphon effect is more significant, the greater the pumping force. But the demand for water is too great to stop. People who have installed siphon toilets in their homes have found that when flushing, the water should first be released to the very high surface, and then the dirt will go down with the water. Its design structure determines that a certain amount of water must be available. To achieve a flush level, at least 8 or 9 litres of water should be used at a time, if forced to reduce the flush to 3/6 litres, you will find that the flush rate is insufficient. Now there are some consumers on the market to reflect the 3/6 litre toilet wash is not clean, is due to this. The toilet should be carefully coordinated. If it is just a water-saving water tank, but matched with a large water storage bucket, it is difficult to achieve real water saving.
2, pipeline area resolution is easy to block
The key of water – saving performance of toilet lies in the coordinated design and installation of the whole flushing system. In the past, the flushing water of the toilet can not be controlled mainly because the toilet is assembled in pieces and the water-saving performance of various departments can not be coordinated and unified. Direct flush toilet is now in the market variety control less, the performance of this kind of toilet is better than siphon type, but now the domestic manufacturers of this kind of mold control less, the market has caused this situation. And this kind of toilet design has no back water bend, accept straight flush, it is not easy to cause blockage in the scouring process compared with the siphon type.
Siphon pipe diameter is about 56 cm, converted into the water area, than the direct impact of about three times, in order to be unusually easy to block when flushing. Some jokingly say that every home that installs a siphon toilet will always have a double kit: a paper basket and a plunger. Because if the toilet paper is thrown directly in the toilet, it is easy to block; And the aftermath, of course, requires plungers.
3. Each has its own advantages and disadvantages
So why now in the sanitary market, siphon occupies the absolute mainstream position? The first to promote American scale brand is the first to enter the Chinese market, people have formed the habit of buying. And the biggest advantage of the siphon is that the flushing noise is low, which is the so-called silent. And the direct rush type because of the use of water is the instant strength of the kinetic energy, so as to hit the wall of the sound is not pleasant, the noise complaints about the bathroom is aimed at this.
Through market research, it is found that people hedge the noise of water is not uncommon, compared to the noise of water after death, because it will last for at least a few minutes. Some toilets are filled with water like a sharp whistle. Direct flushing has no regulations to avoid the sound of direct flushing, but they emphasize the silence of the water. What’s more, people want the flusher to be as short as possible after they go to the toilet, and while the direct flusher provides immediate results, the siphon levitate is also embarrassing. However, the siphon type water seal is high, so it is not easy to overtaste.
Indeed, no matter what flushing mode of toilet is selected, the city can be satisfied and upset place, from the point of view of water saving alone, it must be a little better, but if there is a good quiet at home, the elderly should consider it. Although the siphon is not very perfect in the connection of water saving and flushing, it has been extremely mature in the domestic market, and it is quiet and odorless. To be the final choice of what style, you also have to adapt to local conditions, choose their most valued advantage products.
4. What else to watch besides flushing the toilet
Look at the appearance: split toilet as usual small volume control, suitable for small space toilet; One-piece toilet line circulation, novel design, there are many items to choose from, and in the bottom line of the toilet back bend held blockade disposal, to provide convenience for the future toilet cleaning; In addition, it is very important to investigate the rugged toilet tank, the tank is high, the impulse is relatively large, and the flushing effect is relatively good.
Look inside: In order to save costs, many toilet manufacturers are working in the toilet. There is no glaze in some back water bend, and some use the sealing pad with poor elastic filial sealing performance. Such a toilet is easy to scale up and clog, and easy to leak. Therefore, when buying to use the hand into the toilet in the mouth, touch whether the inside is greasy. The hand is smooth is glazed, coarse is not glazed. The gasket should be made of rubber or foamed plastic, with large elasticity and good sealing performance.
Look at the glaze: the toilet belongs to the ceramic product, the quality of the glaze outside the ceramic is very main. Good glazed toilet seat smooth, careful, no defects, through frequent washing can still smooth as new. If the glaze quality is not good, it is easy to make dirt hanging in the four walls of the seat.
Look at the after-sales: as usual on the market sanitary ware sellers have control of reliable and complete after-sales service. Buyers get free installation and a three – to five-year warranty. In this era, manufacturers work hard to repair and replace parts for free. Even after the warranty period, the replacement is only charged for the cost. However, some small sellers, although allowed warranty but can not provide after-sales service.
