In a recent spot check report on toilets released by the General Administration of quality supervision, inspection and quarantine, some unqualified technical indicators of toilets make people wonder: what exactly do the cleaning function, water seal depth, installation relative position and other indicators mean? What aspects of the performance of the toilet are affected by these "strange" nouns? And when buying a toilet, in addition to the price, shape and water saving, what should we look at in the end?

in a recent spot check report on toilets released by the General Administration of quality supervision, inspection and quarantine, some unqualified technical indicators of toilets make people wonder: what exactly do the cleaning function, water seal depth, installation relative position and other indicators mean? These “ Strange ” What aspects of the performance of the toilet are affected by the noun? And when buying a toilet, in addition to the price, shape and water saving, what should we look at in the end? Experts pointed out that the purchase of toilet should be considered comprehensively, and the key is to see the flushing effect

◆ don't blindly pursue water conservation

the water consumption of toilet is the conventional 3l, 6L and other values. It is understood that some enterprises claim that the water consumption can reach 1.5L, that is, 1.5L of water can be used to wash away dirt. Huyunlin, a professor level senior engineer of the National Center for quality supervision and inspection of building materials, pointed out that now businesses are also promoting toilet water consumption as a selling point, which has also caused “ The smaller the better ” But in fact, this understanding is wrong

according to Hu Yunlin, the smaller the number of liters does mean that the amount of flushing is small, and less water is used to flush dirt, but these are relative. Now businesses blindly emphasize “ Save water ”, But what consumers need to consider is the comprehensive function of the product &mdash& mdash; After saving water, can you flush it. Experts said that there is still a horizontal distance between the toilet and the riser of the corridor. Although the toilet with too small lift can flush the dirt out of the toilet, it may not be able to flush it directly into the riser, resulting in the dirt blocking in the horizontal pipe. Some old houses with long horizontal pipes are not recommended to use toilets with small water consumption

◆ there is little difference in flushing methods

currently “ Impact type ” And “ Siphon type ” The two flushing methods are mainly toilet products. When the reporter visited the market, he found that the salesperson's views on these two flushing methods are very different. For example “ Siphon type ” Merchants advertise that their products have low noise, while the straight down type promotes water saving, and the straight siphon toilet needs to stay for a period of time when flushing, otherwise it will not be washed clean and inconvenient. What is the truth? How should consumers choose

“ No matter what kind of flushing method, the key depends on whether it is dry& rdquo; Hu Yunlin said that the flush toilet really saves water, and the sound of the siphon toilet flushing is indeed slightly smaller, which can be ignored unless consumers have a high demand for water saving and noise prevention. As for “ Siphon type needs to press the button continuously for a period of time when flushing ” Experts said that the toilets of both flushing methods need a continuous stay process, otherwise they are not fully started by piece, and the floating bucket is not high enough, which is not easy to flush, and may also lead to water leakage accidents. Therefore, as long as the flushing is clean, no matter which flushing method, consumers can choose, and there is no substantive difference between the two

◆ cleaning function is very important

introduction of Hu Yunlin, “ Cleaning function ” Refers to “ The ability to discharge water and flush it at one time ”. If you can't flush it at one time and have to flush it again, it will cost water. Some urinals reduce the water consumption of urinals in pursuit of water saving. If the cleaning function is not good, the gains will outweigh the losses, which is not really water saving

◆ low reference value of water absorption

“ Water absorption ” Refers to the toilet material &mdash& mdash; The water absorption of the ceramic itself. The higher the water absorption, the easier it is to absorb dirt. Hu Yunlin believes that since the surface of the toilet bowl now has a layer of glaze, which is very smooth, the size of the water absorption itself has no great reference significance. Most of the unqualified items in this project are the inconsistency between the water absorption of the product itself and the marked water absorption

◆ pay attention to the diameter of the pipe

when selecting the toilet, pay attention to the minimum diameter of the pipe. Experts said that if businesses can provide corresponding tests, consumers can put a table tennis ball to see if it can be rushed. Generally speaking, if the pipe diameter is too small, it is easy to block. When choosing, consumers can also touch the pipe to see whether it is smooth and whether the glaze is even

◆ don't forget to check the water level line

the water tank is the place for water supply and storage. When buying a toilet, consumers can check: under normal circumstances, the inside of the toilet tank should have the following rules: during normal operation, the water surface height should be lower than the overflow port height, and the water outlet height should be higher than the overflow port height and marked with “ CL” Signs& ldquo; CL” Line, also known as the safety line, the water surface must not be higher than this line to prevent the water in the water tank from returning to pollute the water supply pipeline when the water supply pipeline stops and the pressure drops, which is also “ Technical requirements for safe water level ” Content of. If there is this line, it means that the manufacturer has at least noticed this

◆ the water seal relationship is clean and sanitary

“ Water seal depth &rdquo& ldquo; Water seal surface area &rdquo& ldquo; Toilet water seal reply ” And other indicators determine whether the toilet will smell back. Hu Yunlin pointed out that the national standard for “ Water seal depth ” And “ Water seal surface area ” There are clear specified values& ldquo; Water seal depth ” Insufficient, it is easy to cause the odor in the sewage pipe to return indoors. Different manufacturers use different molds and carry out transformation according to the characteristics of their own kilns. Some ceramics may be deformed during the firing process. Therefore, it is likely that the water seal depth of products of the same brand and model is different, which may also cause the unqualified index of different products of the same brand and model. Too small water seal surface area will lead to easy contamination& ldquo; Water seal reply ” It refers to the replenishment of new water flow after flushing the toilet. The new water flow should be replenished quickly and maintained at a certain height

◆ pay attention to the details of bathroom installation

whether it is a toilet, bathtub or basin, the installation quality also has a great impact on the later use of the product, and some details have to be paid more attention to

pedestal pan: some workers will use mounting bolts to fix the pedestal pan on the ground when installing the pedestal pan, and seal the base with cement, etc. Hu Yunlin believes that this method is not recommended. First of all, when fixing the bolt, it is easy to exert too much force, resulting in the fracture of ceramics; If the bolts are too tight, it is easy to cause ceramic cracking; In addition, the expansion and contraction rates of cement, ground and ceramics are different, which may lead to the expansion of the toilet. He suggested that sealant can be used to fix the toilet on the ground, which can not only fix, but also seal

basin: Hu Yunlin pointed out that if it is a basin under the stage, it is best to use a bracket to hold it. Although some people use sealant with high strength to fix the basin under the table, it may cause the glue to pull the basin apart

bathtub: when installing the bathtub, the ground should be leveled first, and the bathtub should be kept at a certain slope to facilitate the rapid discharge of waste water, rather than forming a puddle in the bathtub. Hu Yunlin pointed out that the bottom of the bathtub needs to be padded. Otherwise, even if there are supports around the bathtub, if the bottom is empty, it is easy to cause deformation of the bathtub and affect its service life. Sealing the bathtub and the surrounding walls with sealant is also a link that cannot be ignored to avoid the return of odor. He also reminded that maintenance holes must be reserved to facilitate maintenance in case of problems
