"On the one hand, manufacturers should strictly control the quality of production and improve the safety index as much as possible, and must not take the product characteristics as an excuse to treat it lightly. On the other hand, suppliers should inform customers of such risks, so that they can know the precautions for use and do daily protection. " The relevant person in charge of Zhenjiang Consumers Association said that the so-called "three thousandths of self-explosion rate" means that the accidental self-explosion rate of glass products can be allowed by default in the industry. However, at present, the country does not explicitly stipulate that tempered glass has a self-explosion rate of three thousandths, but it is generally accepted in the industry. There is no mention of self-explosion in the national standard of tempered glass, but only the impact resistance and the state after bursting of tempered glass.
"No matter whether the self-explosion rate of three thousandths is allowed by the state or not, it can't be the reason for the operators to shirk their responsibilities." The person in charge of the Consumers Association said that the glass panel of the computer display screen of the range hood is likely to burst, and the sales staff should inform consumers in advance before buying and using it, which is also a requirement to protect consumers' right to know.
At the same time, the legal adviser of Consumers Association hopes that manufacturers can fully respect consumers' right to safety and information in the future, further improve product quality, standardize product descriptions and warning signs, nip in the bud, let consumers use assured products, and reduce or even eliminate such dangers.
through the coordination of Zhenjiang consumers association, the manufacturer of range hoods finally promised to replace the selected range hoods for Ms. Shi, the consumer, for free.
according to the smoke exhaust structure, range hoods can be divided into three types: top suction type, near suction type and side suction type.
top suction type: the top suction type range hood places the fan system at the top of the smoke collection cavity, and the air inlet directly faces the rising oil fume, so that the oil fume can be quickly discharged by reducing the vortex time of the oil fume in the smoke collection cavity. It adopts a completely closed smoke exhaust room, which is completely isolated from the inside of the machine body. The oil fume is separated by filtering the oil net, which reduces the erosion of the oil fume on the motor and the fan blades, and at the same time, the exhaust air volume is fully improved, so the oil fume absorption effect is better. In addition, the top-suction range hood adopts an integrated process in the structural design of the smoke collection cavity, which is very convenient for daily cleaning. Therefore, whether you choose Chinese or European range hoods, top suction range hoods should be your first choice.
near-suction type: the smoke collection cavity of the near-suction type range hood adopts an open structural design. Compared with the top-suction type range hood, the air inlet of the near-suction type range hood is closer to the source of the oil fume, which shortens the moving distance of the oil fume and makes the smoke exhaust effect more ideal. Because the open style is adopted in the appearance of the smoke collection cavity, the range of cooking space is increased, so that there is no sense of depression when cooking. If you are a person who advocates freedom, this kind of products should be your best choice.
side suction type: the fan system side of the side suction range hood is placed on the side of the smoke collection cavity. Compared with the top suction type structure, the smoke will form a vortex in the smoke collection cavity, and the smoke exhaust effect is not as obvious as that of the top suction type. At the same time, due to the structural limitation, the smoke collection cavity often cannot be integrally formed. Generally, oil guiding and discharging are realized by the internal oil circuit of the machine body, which is more troublesome when cleaning. Therefore, side suction range hoods have been gradually replaced by top suction range hoods and near suction range hoods.
people in the industry suggest sticking an explosion-proof film on the surface of tempered glass, which can minimize the damage caused by glass self-explosion. Even if the glass is broken, it still sticks together, effectively reducing the harm caused by glass self-explosion and preventing people from being injured in accidents. In addition, tempered glass can also be replaced by stainless steel, thus avoiding the possibility of self-explosion.
