1. Can kitchen fumes be completely removed? 2. Can the lampblack be separated so that the fan can be effectively protected? 3. Is it simple and convenient to clean? 4. Is it energy-saving and super effective 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 suspended 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.
