Open kitchen is a trend of decoration at present, but the problem of oil smoke pollution must be solved. How can I choose a range hood that keeps the kitchen as clean as the bedroom forever?
From the standpoint of consumers, there are four criteria for evaluating the quality of range hoods:
1, can you completely smoke the kitchen? You can separate the oil from the smoke and let the fan
Get effective protection
3. Is cleaning simple and convenient? 4. Do you save electricity and maintain super efficacy for a long time?
Using the above four standards to examine the traditional range hood, it is natural to understand the reasons why the range hood industry has been unsatisfactory for so many years.
First of all, traditional range hoods are designed with ceiling, and the installation height is generally around 700mm, while the fan power of their mainstream models is mostly between 200 and 250 watts (the national standard requires that it should not exceed 200 watts), so the effective suction radius is around 300-400 mm, so the disk surface is completely out of its fan suction range, so only a part of the lampblack generated by the disk surface with lower density than air can rise to the fan suction range, and the rest. If you want to suck it clean, from the aerodynamic principle, you can only reduce its height and let its effective suction radius cover the pan surface, which can naturally reach more than 99% suction, but obviously it is impossible to cook. After careful analysis, it is not difficult to find that this is the fundamental reason why the traditional ceiling smoke machine can't smoke cleanly.
Second, the traditional range hood uses an oil filter for oil fume filtration. There are one, two or more layers, and the filter holes are square, diamond and round. I hope to block the soot through the filter. However, judging from the use of this scheme for so many years, the effect is very poor. A well-known brand's publicity materials admit that even if the filter hole is as small as 0.0 1 cm2, it can't stop 37% of the oil fume. Now the filter hole of most hoods on the market is 0.06. So it is almost directly discharged. The inner wall of the range hood is polluted, which leads to a large amount of uneven oil accumulation on the fan impeller, and the rotation of the fan loses its dynamic balance, so the suction effect is getting worse and worse, and its mechanical noise is getting louder and louder. In short, the lack of effective purification function is the fundamental reason for the rapid decline of the efficiency of traditional smoke machines until they become furnishings.
Thirdly, due to the defects in the ceiling design and the lack of effective purification means, in order to ensure the short-term air extraction effect, its power is generally high (the mainstream model is between 200 W and 250 W), which obviously consumes a lot of power, and its motor power almost exceeds the upper limit stipulated by the national standard.
Fourthly, because there is no effective purification method, a large amount of oil accumulates in the inner cavity of the fan and machine, which is very difficult to clean and generally needs professionals to complete. Sometimes the effect is worse after cleaning, which is time-consuming and laborious. On the other hand, Goehringer cyclone range hood adopts patented arc design and wind tunnel rectification technology, with side air intake and wall-mounted installation, which cleverly reduces the air intake greatly, does not occupy the user's cooking operation space, and only smokes oil fume without flame. It has been sampled and signed by the National Household Electrical Appliances Testing Institute, reaching 99% suction effect. At the same time, the patent hyperboloid vortex separator achieves 90.5% purification effect through secondary oil smoke separation. Thus effectively protecting the fan, and naturally prolonging the service life of the whole machine (generally twice that of the traditional range hood). Patented separation of upper and lower separators, high efficiency and energy saving, greatly reducing the power consumption of the whole machine. Maximum power 160W (weak gear is only 60W), saving electricity by 30% compared with traditional range hoods. Therefore, we have obtained "China Environmental Protection Product Certification Certificate" and "China Energy Saving Product Certification Certificate". Moreover, the inner wall of the machine and the fan do not need to be disassembled and cleaned, and the upper separator and the lower separator can be conveniently taken down, so that ordinary family members can be competent in cleaning and defecate freely and easily.
Gehringer's product characteristics
L enterprise core technology
The company innovatively applied aerospace technology to the research and development of range hoods. The company's original hyperboloid "vortex" oil fume separation technology, wind tunnel rectification, side air intake and design patent technology make the oil fume absorption rate of the product reach 99.0% and the oil fume purification rate reach 90.5%, ensuring that the inner cavity of the range hood is clean enough for a long time, and truly realizing lifelong disassembly and washing-free; At the same time, ensure that the suction port of the range hood can be close enough to the pot edge, and create a clean, warm and healthy environment inside and outside the kitchen. Its appearance is undoubtedly a technological revolution in the development history of pumping units at home and abroad. Completely change the backward status quo of range hood technology and improve the upgrading speed of range hood products.
Wind Tunnel Rectification Technology: Ensuring Lower Installation
After the range hood is turned on, the fan rotates at a high speed, producing a moving rotating airflow. When the airflow passes through the separator, the oil fume separator (rectifier) designed according to the wind tunnel rectification principle transforms the irregular airflow into a uniform, flat and soft airflow, ensuring that the air inlet can be close enough to the pot body, and the wind will not disturb the flame, so that the oil, waste gas and peculiar smell will be sucked away as soon as they are produced, and the suction and discharge will be more thorough, and even the fried peppers will not smell choking. The smooth airflow generated by the wind tunnel rectification technology also ensures that the oil fume will not rotate or be disturbed before entering the air inlet, and avoids the grease in the oil fume being thrown around the air inlet due to the rotation of the airflow, which will damage the kitchen environment.
B. lampblack separation technology: completely separate lampblack.
When the range hood is working, the rectified airflow will bring the lampblack into the separator according to the law of first slow and then fast (the wind speed at the inlet is nearly 3m/s), and generate high-speed vortex in the hyperboloid separator. Under the action of centrifugal force, 90.5% of the oil will be separated from the flue gas, adsorbed on the pipe wall of the separator, and naturally flow into the oil cup below with the pipe wall. Then the fan is separated for three times, so that cleaner air can be effectively discharged from the kitchen, and the oil fume purification rate is high enough, and there is almost no oil accumulation on the inner wall of the fuselage and the fan. The upper partition plate and the lower partition plate can be conveniently taken off and cleaned at will with ordinary detergent, thus realizing lifelong disassembly and no washing. Because the wind wheel does not accumulate oil, it maintains a balanced state for a long time. Therefore, the natural life of the motor can reach about 15 years. At the same time, it is ensured that the exhausted gas will not pollute the outdoor environment.
C side air inlet:-cleaner suction inlet
The upper and lower separators are distributed in an arc shape, and they are combined into a gas gravity field when working. The lower separator is installed at a lower position near the pot. The upper separator is installed at a higher position, and a certain radian is set to prevent the oil fume from spreading. When cooking, the oil fume is always within the wind range of the separator from generation to discharge.
Traditional range hoods, whether Chinese or European, are mostly installed with suspended ceilings, and the pan surface is far from the air inlet of the range hood (used for cooking), so the machine can only absorb the rising oil smoke and the air above the pan surface in the first three directions, and the oil smoke naturally emitted below cannot be completely absorbed. The effective exhaust air volume really used for smoke exhaust is less than one third of the original standard value. Gehringer smoke machine adopts side air intake technology, and almost all the exhaust air per minute 16.6 cubic meters is used to exhaust smoke, but the flame is not affected at all. So as to realize the pumping effect with small displacement and high efficiency. So that there will be no smoke escaping from the whole kitchen.
At the same time, the "side air intake" can make the "total pressure efficiency" of the fan reach 24.9%. The "total pressure efficiency" is an industry index to measure whether the range hood is energy-saving, and it is the efficiency of converting electric energy per unit power consumption of the fan into wind energy. At present, Goehringer is the first batch of energy-saving products in the range hood industry, with the power of 160 W (only 120 W), which is the same as the total pressure efficiency generated by the traditional range hood of 200W W, and can ensure the minimum power consumption, saving more than 30%-50% compared with the traditional range hood. It is a real energy-saving range hood.
L product features:
1) The oil smoke absorption rate is 99.0%, even if the pepper is fried, it can't smell the choking smell, which ensures that the body is not harmed by oil smoke and the kitchen air is fresh.
2) The oil fume purification rate is 90.5%, the oil is completely separated, and the outdoor air is clean.
3) The input power of the motor is 160W, and the energy-saving little prince is only 120W, which saves more than 30% electricity compared with the traditional range hood.
4) Because the grease is separated by the separator, there is no oil accumulation on the inner wall of the fuselage and the fan, so it is really free from disassembly and washing (just clean the separator).
5) Wall-mounted design, no meeting, no oil dripping, more space saving.
6) Under the protection of the separator, the impeller of the fan does not accumulate grease, which keeps efficient operation for many years, ensuring the smoking effect and the service life of the fan.
7) Due to the accumulation of a large amount of oil in the wind wheel and fuselage of the traditional smoke machine, the wind wheel loses its balance and the noise will increase with the increase of service time. Because the fan of Glinda is effectively protected, the noise will not increase from purchase to the end of service life.
