7. Functional Requirements
7.1 Flushing function
(1) The full flushing of single-stage toilets and double-stage toilets shall meet the functions of washing, solid matter discharge and sewage replacement under the specified water consumption (the sewage replacement test, the dilution rate shall not be less than 100. For double-stage toilets For the sewage displacement test of the stall flush toilet, the small stall flush, the dilution rate should not be less than 17), the water seal recovery function (not less than 50mm), the splash resistance and the drainage pipeline transportation characteristics.
(2) The small-stage flushing water of the double-stage toilet shall meet the requirements of the washing function, the sewage replacement function and the water seal recovery function under the specified water consumption.
7.2 Load resistance
The load resistance test shall be done, and there shall be no deformation or any visible damage after the test.
7.3 Flush Noise
The cumulative percentage sound level L50 of toilet flushing noise shall not exceed 55dB, and the cumulative percentage sound level L10 shall not exceed 65dB.
8. Design Points
8.1 Coordinated design
1) The bottom row toilet must be equipped with a vertical downpipe passing through the floor, and special attention should be paid to the waterproof treatment after the floor is passed through the pipe.
2) The special hose for the rear toilet is connected to the horizontal drainage pipe on the building, and there is no sewage pipe passing through the floor (except for the main sewage riser). The waterproof treatment of the bathroom floor is simple and reliable.
3) The distance between the center of the drainpipe of the lower-row toilet and the finished wall after decoration (referred to as the wall distance). The current national standards for sanitary ceramics unify it into three dimensions of 200mm, 305mm, and 400mm. The wall distance of the sewer pipe in architectural design should be Click here to execute. The thickness of the facing brick (about 20-25mm) should be considered for the wall surface of the bathroom in the rough room.
4) The rear-mounted hanging toilet (the installation distance of the sewage outlet is 100mm and 180mm respectively) is widely used in foreign countries but rarely used in China. The floor is easy to clean, and the sewage horizontal pipe (even the toilet water tank) is buried in the wall. , the building needs special design.
8.2 Water seal depth
The water seal and odor isolation of sanitary ware is a hygienic requirement. The new standard for sanitary ceramics stipulates that “the water seal depth of all sanitary ceramics with integral traps shall not be less than 50mm“.
8.3 Water-saving products
1) In new residential buildings in large and medium-sized cities, the use of toilets with a flushing water volume of more than 9L (excluding 9L) is prohibited, and the use of toilets with a flushing water volume of 6L is promoted.”
2) There are a variety of flush-down, siphon and jet siphon water-saving toilets on the market that have passed the water-saving product certification and are available for selection. Among them, the spray siphon toilet has low flushing noise, high water surface (not easy to stick stools), high sewage replacement rate, and rapid sewage discharge by spraying water. It is a water-saving toilet with better comprehensive performance. Although the vortex siphon toilet also has the advantages of good sewage discharge performance and low flushing noise, it is regarded as a high-end product, but the flushing water consumption of such products is more than 6L, which is not a water-saving product and should not be used.
9. Development Trend
9.1 Save water
Water saving and high performance are the general trend of toilet development. At present, natural hydraulic 4.5/2.9L double-stage ultra-water-saving toilets (50mm super-large pipe diameter) and non-flush urinals are all produced, and special-structure jet-type and dumping-drainage water-saving toilets can also be mass-produced.
9.2 green
“Green building sanitary ceramics” refers to building sanitary ceramic products that have a small load on the earth’s environment and are beneficial to human health in the links of raw material collection, product manufacturing, use or recycling, and waste treatment. All building and sanitary ceramic products that have passed the environmental labeling product certification and are affixed with the ten-ring green label should be given priority.
9.3 Decoration
Sanitary ceramics have traditionally been glazed raw and fired in one shot. High-grade sanitary ceramics have introduced the decoration process of daily-use porcelain into the production of sanitary porcelain. The sanitary porcelain after the first firing is then painted with gold, decals, and painted, and then fired (color fired) for the second time, making the products elegant and elegant.
9.4 Cleanliness
1) Self-cleaning glaze makes the glaze surface smoother, or coating with nano-materials to form a surface hydrophobic layer, so that the surface of the product has a self-cleaning function, no water, no dirt, no scaling, and improved hygienic performance.
2) Antibacterial products: silver, titanium dioxide and other materials are added to the sanitary enamel, which has a bactericidal function or a bactericidal function under photocatalysis, which can prevent the growth of bacteria or mildew on the surface and improve hygiene.
3) The toilet is equipped with a paper pad replacement device: the paper pad box device is installed on the toilet in the public toilet, and the paper pad can be replaced conveniently, which is safe and hygienic.
9.5 Multifunctional
Abroad, there are automatic urine testing devices, negative ion generators, fragrance dispensers and CD devices installed on toilets, which improve the functionality of the toilet and the pleasure of use.
9.6 Fashionable
High-end sanitary ceramics series products, whether simple or luxurious, all emphasize the need to have a distinctive personality, but without losing health and comfort, this is fashion.
9.7 Product replacement
The function of the ceramic toilet seat ring (bath cleaner) with flushing and drying is becoming more and more perfect, so that the toilet has the function of the bidet, and the actual use is better than the bidet, which makes the ceramic bidet tend to be eliminated.
