The hood machine is one of the most important parts of the kitchen in daily life. If you don't want to be smoked into a hooded face, you can choose a good hood. The household Range Hood is divided into three. Kinds: One is a Chinese hood, the other is a European hood, and the third is a side suction. So is the side range hood good or the near suction range hood? What kind of range hood is good? I believe it is one of the topics worthy of attention for interested friends. Next, the decoration home decoration network Xiaobian will give a detailed introduction to what kind of range hood is good , so that users can understand the range hood in all directions:
First, what kind of range hood is good
1. Near suction range hood
The near-suction range hood is a wall-mounted near-suction installation, and the air inlet is as close as possible to the pot surface, only 0cm-10cm; it creates conditions for exhausting the fumes. The near-suction range hood has a high installation air inlet close to the surface of the pot. When the hood is in operation, a large-scale negative pressure zone airflow barrier is formed around the cooktop, and the oil pan is covered therein. The soot rises from the pot surface, and it is too late. Diffusion, immediately inhaled into the air inlet with the airflow, the effect of the oil smoke is very good, the smoke smoke removal rate can reach more than 99%. Thanks to the close installation, the use of a smaller power motor can also achieve satisfactory results, low noise, energy saving and money saving.
2, ceiling mounted range hood
European-style and Chinese-style hoods are mostly ceiling-mounted, and the air inlet is about 70cm away from the stove. Because of the long distance from the surface of the pot to the air inlet, the large motor power and the large air volume capacity are difficult. Absorb the fumes. Due to the ceiling-mounted European-style and Chinese-style range hood, the air inlet is far away from the stove. Only by increasing the power of the motor to compensate for the lack of suction, the noise is obviously increased, but the effect of exhausting the smoke is still not satisfactory. Test data shows that the soot absorption rate is less than 70%. The ceiling design and installation height determine that the soot suction passage is from the pot surface to the vertical direction of the hood. High-density and high-pollution fumes must pass through the head of the human body when entering the hood through the ascending passage. Easy to inhale fumes, seriously endangering human health.
3. Chinese-style range hood, this kind of hood generally has a deeper (larger volume) collecting chamber. When the fan rotates at high speed, a certain negative pressure zone is formed above the collecting hood to accommodate the fumes that are too late to be discharged. , played a buffering role, thus avoiding the phenomenon of a large amount of soot diffusion. In the past two years, the power of Chinese-style hood motors in the market is generally between 150W and 200W.
4, European-style range hood, relative to the Chinese style, the smoke collecting chamber of this hood is relatively shallow, but relatively wide, generally 90CM. Many consumers think that the Chinese hood is better; in fact, most of the domestic hoods are designed according to the Chinese principle, but the appearance is European, the wind road design is Chinese, and it is improved on the basis of Chinese. (For example: the fan is increased, the power is increased, and the wind wheel is widened). Therefore, although the European hood does not have a large-scale smoke collecting chamber of Chinese style, its air volume and wind pressure are generally larger than those of the Chinese model, so there is no need to worry about the use effect:).
5, side suction range hood, also known as near suction. In the past five years, the structure of the hood has been similar to the above two types. The main features are low smoking, forcibly changing the direction of the soot, and inhaling the machine before the soot spreads. Many brands of such hoods on the market have little power but are discharged. The smoke effect is still good. Moreover, such a hood is generally installed without a head due to the installation of a wall, and has no feeling of depression. There is also a very important point to remind YUYU that the smoke machine should be selected as much as possible with a soot separator (pictured below). This type of separator can generally separate more than 85% of soot and keep the machine clean for a long time. Extend the cleaning cycle of the fan.
Second, the selection index of range hood
1, the amount of air
The air volume refers to the amount of exhaust air per unit time of the range hood when the static pressure is zero. The state stipulates that the indicator value is greater than or equal to 7m3/min. This shows that the air volume is a very important indicator. In general, the larger the air volume value, the faster and more timely the suction of a large amount of fumes in the kitchen. Therefore, YUYU is selecting a range hood. When other indicators are good, try to choose a range hood with a larger air volume. By the way, the amount of wind is not how big it is to design, it is subject to many factors. At present, the air hood of the market has a wind volume of 14m3/min, which is not bad.
2, wind pressure
Wind pressure refers to the static pressure value when the wind hood of the range hood is 7m3/min. The state stipulates that the indicator value is greater than or equal to 80 Pa. But now the general hood wind pressure is more than 180Pa, the largest is almost 300pa. Wind pressure is also an important indicator to measure the performance of the hood. The greater the wind pressure value, the stronger the anti-winding ability of the range hood; if the exhaust pipe is long or connected to the public flue, the exhaust pressure is greatly lost, so that a larger wind pressure is required to ensure the smoke Gas is discharged. Therefore, when other indicators are good, the greater the wind pressure value, the better. Similarly, wind pressure is subject to many factors, as is the wind.
3, noise
Noise is also an important technical indicator to measure the performance of the range hood. It refers to the A sound power level measured by the specified method when the range hood is operated at the highest speed and rated frequency. The state stipulates that the indicator value is not more than 74dB. For this indicator, we know that the smaller the noise, the better.
4, motor input power
The model of the range hood is generally specified as CXW-□-□, where the number in the first “□” indicates the input power of the main motor. Nowadays, many consumers have a misunderstanding about the input power of the range hood (may be caused by the misleading of some promoters), and the higher the power, the better. In fact, it is not necessary. There are three reasons: First, the manufacturer increases the power to increase the air volume and wind pressure. If the air volume and wind pressure are not improved, what is the use of increasing power? Second, the higher the power, the greater the noise. Third, the electricity, the country does not advocate water-saving and power-saving?! Some manufacturers, the input power is only 150W, it is hard to mark it above 200W.
As long as you grasp the above indicators, you can determine the advantages and disadvantages of the range hood. There is also a leak problem that is also important, but there is currently no indicator to measure. The key is whether the process of collecting the smoke chamber is integrated or seamlessly welded. The knowledge of the range hood is described here. I hope everyone can read this article carefully. If you want to know more about decoration, please continue to pay attention to the decoration home network.
