China's current extension of the hood prototype are berai products, is imitation of Germany, Italy, Japan and other countries of the model, these countries more than the use of electric cookers, and the oil temperature is only about 130 degrees Celsius, so the smoke is very small. China's cooking habits are strong oil fire, oil temperature up to 270 degrees Celsius or more, can produce a lot of smoke. Almost all the hoods on the market now is the ceiling type, pot mouth and air inlet distance of 60-75CM, this suction method, not only to overcome the weight of the smoke itself, but also due to the hood's air inlet away from the stove is too far away, can only suck away the rising smoke, the following natural distribution of smoke there is no way to suck, resulting in a large number of fugitive fumes hazardous to human health, and seriously pollute the kitchen environment, bringing great trouble to our daily life. It brings a lot of trouble to our daily life. And in the process of using, easy to drip oil, touch the head and other phenomena, and even more due to the accumulation of too much oil and fire.
Many users in the selection of range hoods, it is easy to be attracted by the appearance of luxury or inexpensive machines, coupled with the advantages of some brands of smoke machine advertising, so ignored the selection of the most critical indicators of smoke machine, that is, the smoke absorption rate. The domestic range hoods, most of the focus on the appearance, or thin the machine, or the choice of tempered glass, in fact, in the smoke absorption rate is not much of a breakthrough.
Currently on the market, the traditional brands of hoods in the publicity only emphasize the power, exhaust volume, smoke thoroughly, but did not promise to absorb how much smoke, the concept of fuzzy, misleading consumers, so that consumers wrongly believe that the greater the power, the better, the more the better, but the use of, but found that with the publicity of the distance is very far. Consumers also tend to forget that they are choosing the hood, as long as they think it is a brand, the appearance of beautiful on the line, the hood to buy a misunderstanding is thus generated.
People generally believe that the suction power of the range hood depends on the size of the motor power, in fact, not. With the absorption rate and purification rate of the high and low to identify the hood in addition to the effect of fumes is the most accurate method. According to the latest international environmental standards for home appliances, smoke absorption rate, purification rate can be completely quantified. With the hood's smoke "absorption rate" high and low to identify the effect of its removal of fumes is the most correct method.
The "suction rate" is a percentage of the cleanliness of a range hood, which is an important data for SAKURA's R&D center and quality management organization to test and examine the performance of range hoods. It refers to the efficiency of a range hood in removing fumes completely in a specified condition and within a specified time. Because the "suction rate" directly to the smoke effect to judge the performance, so consumers in the purchase of hoods, with "suction rate" high and low to judge the performance of the hood is very objective, direct and correct method.
"Purification rate": excellent quality hood not only to have a very high absorption rate, but also have a high purification rate to meet national environmental emission standards, to make a contribution to the cause of human environmental protection! Merchants or products do not promise purification rate, proving that the product purification rate is insufficient to meet the environmental standards, the best choice of criteria is environmental certification!
At present, there are only three companies in the international arena that can achieve this standard: First, a French company's newly developed hood, which will form an air cover when it is turned on so that the fumes can't escape, and it can absorb 100% of the fumes, which is priced at 12,200 francs, and is suitable for use by aristocratic families only. Second, a German company's newly developed hood, when cooking can automatically adjust the height and direction, can also absorb 100% of the smoke, but the price is also very high. Thirdly, a kitchen hood developed in Chengdu, Sichuan Province, China, in recent years, which is suitable for Chinese cooking habits, is the first to put forward the concept of "suction rate" and "purification rate" in the range hood industry. It has obtained the Type III Environmental Labeling Certification issued by the China Environmental Labeling Certification Committee! The aerodynamic principle of aerospace technology and the unique secondary filtration device make the grease and smoke sucked away and fully purified, and it is the range hood product with a suction and purification rate of more than 99%, and it is also the brand that dares to quantify the suction and purification rate of grease and smoke in the market. Its birth will set off a green revolution in the kitchen, the hood era is about to pass, the hood era has come!
How to choose a range hood
The introduction of the range hood, so that people get rid of the traditional kitchen smoke and fire conditions, thus making the kitchen revolution a real step forward. After more than a decade of development and updating, the main styles of range hoods are thin (including wind screen type, bullet type, double cover suction type), semi-deep type (induced, triangular type), deep type three.
Smoke absorption effect is not satisfactory
Currently most families use a thin range hood, but from the effect of smoke absorption, not satisfactory. Thin range hoods due to the body of the suction port and the distance from the pot surface is far, so that the smoke in the process of rising to spread around, not all into the suction port, ultimately leading to poor results in the suction of fumes. Mr. Shen's home is a double cover suction type range hood, the body of the specified non-oil. But we found that the whole range hood oil stains, and sucked up the oil can not completely flow to the oil storage box, Mr. Zhang said: "Every time you cook, due to the smoke can not be smoothly discharged from the exhaust pipe, making the kitchen full of fumes, to buy a range hood was intended to clean the kitchen, do not want to achieve the purpose of the purpose of the unclean." Ms. Wang's home is the use of deep-type range hoods, this range hood Yang to solve the rise to the hood on the hiding place of the smoke, but the inhalation of the range hood and the pot surface of the distance increases (due to the body mounted on the low to touch the head), and due to the high air ducts, so that the smoke into the hood is not smooth, the effect of suction fumes is also not very satisfactory. From the above several user surveys, the current range hoods do not make people optimistic about the effect of exhaust fumes. At the same time, the current market range hood Yang is only the provisions of the wind pressure and power, and not for the smoke absorption rate and other real services to the user's indicators to make a commitment.
Noise can not be ignored
According to Mr. Shen reflected, his home range hood just started to use, the noise is relatively small, but now cooking, an open range hood, the sound is very big, just like a car. On this issue, the reporter interviewed the people concerned, according to reports, causing the range hood noise is mainly due to two reasons: First, the range hood is not cleaned for a long time, resulting in too much grease on the wind wheel and the motor, resulting in too much range hood noise. Secondly, some companies drilled the standard loophole, harming the interests of consumers.
Dismantling and washing are inconvenient
Whether it's a thin range hood or a semi-deep range hood, users generally reflect that it's extremely inconvenient to dismantle and wash. Mrs. Rong said: "My home range hood when I bought the business that does not stain the oil, but use less than a month, the body is covered with oil, and the old oil leakage, oil dripping, each time to dismantle the wash have to use three or four hours, very troublesome
Secondary pollution poses a hidden danger
Domestic use of range hoods are direct-exhaust type, that is, the machine inhaled fumes gas is directly discharged to the outdoors (or *** enjoy) flue), the result is that the user's indoor air is clean, but the outdoor air is polluted, resulting in secondary pollution. Ms. Duan said: "Every time at noon, each household range hoods open, the air is full of oil smell, are people afraid to go out. Manufacturers in the production of products should pay attention to environmental issues?
Consumption needs to be guided, the development and production of a device that can both eliminate fumes and fumes treatment is necessary.
How to buy low installation, side air intake hood
With the promotion of low installation, side air intake hood, the form of this hood is gradually recognized by the majority of consumers, there is competition in the market, for this new product, consumers must pay attention to a few issues when selecting:
1 Installation of the height of the problem: the regular range hood suction rate should be more than 99%, to achieve such a high absorption rate of the installation height has certain requirements, if the installation height is too high, the smoke will spread from the bottom of the machine, thus affecting the absorption rate.
2 The problem of noise: because the smoke is inertial rise, to let it rise to the human chest is all suction, relying on the wind speed, so the smoke separation plate requirements are higher, if the separation plate of the structure and material is not standardized, will result in a greater noise, and at the same time, the greater the power, the greater the noise will also be greater.
3 The problem of wind speed: due to the low installation, the side air intake hood suction smoke rely on wind speed, to achieve a suction smoke wind speed, is the need for the whole machine to match the various links, if the wind speed can not reach, will inevitably affect the suction rate.
4 machine surface and oil tank: due to the hood installation height from the stove closer, so the surface of the body must be high-temperature treatment, especially from the fire nearest the oil tank, if not handled properly or even fire hazards.
5 Relevant test reports: not all of this form of installation can achieve the effect of the hood, it is necessary to have the relevant national comprehensive test data. Including: suction rate purification rate noise ground resistance leakage current and a series of indicators, all to comply with national standards.
Consumers in the market to see similar hoods, in the selection of products should pay attention to the problem:
1 Whether the relevant procedures are complete. Whether the technical indicators provided in the brochure are based on.
2 Check the separation plate in front of the machine, whether it can be opened for easy cleaning. Briefly understand the working principle of the separation plate. This is quite important.
3 Check whether the material of the separation plate is in line with the publicity. Does it have a certain degree of hardness.
4 Turn on the machine and listen to the sound when the machine is running.
5 Ask about after-sale promises.
Purchase of range hoods to pay attention to the problem
No matter how the form of range hoods change, there are still certain principles to be followed when purchasing -
1. Non-oil, free of dismantling and washing propaganda is not gullible. Good hood, no matter how the advertisement introduces non-stick, free from dismantling and washing, because there is no smoke purification device or purification process, it is inevitable to be polluted by the smoke.
2. Plastic turbine fan page machine is not desirable. Some manufacturers in order to reduce costs, the fan of the turbine fan page into plastic. In the kitchen such an environment, plastic turbo fan page is easy to age and deformation, but also inconvenient to clean, so consumers should be as far as possible to buy metal turbo fan page hood.
3. The automatic smoke detection function is not useful. Some range hoods through the installation of smoke probes to realize the automatic opening of the hood, subject to cost constraints, these simple smoke probes can not withstand the kitchen smoke and fire as well as grease pollution, will soon be out of order, so the hood of the automatic detection of smoke in the hearing is not useful, the consumer does not have a great need to choose to use this function of the range hood.
4. Grid and fan turbine fan page difficult to remove the model is not preferred. The cleaning of the range hood is the user to buy the daily maintenance work in the most important work. Some range hoods run for a period of time after the noise increases, the amount of exhaust is also reduced. This is mainly the hood fan turbine fan page is condensed on the adherence of grease, resulting in fan fan turbine fan page dynamic balance is damaged, if not dealt with in a timely manner, it will both increase the resistance of fan bearings and noise, but also affects its life. Therefore, the purchase of range hoods should be selected without any special tools can easily dismantle the mesh and fan turbine fan page models. At the same time, you should also carefully observe the hood surface should not have seams, in order to more thoroughly and more easily cleaned.
