In daily life, the range hood is one of the most commonly used household appliances. The range hood is responsible for sucking away the fumes and preventing the air in the kitchen from being polluted. Therefore, choosing a good range hood is the most important thing. What kind of hood is good ? How should we choose a range hood? Here's how to choose a good range hood for the decoration home decoration network.
What should be paid attention to when the range hood is good or bad?
1. Safety performance: As a household appliance product, safety is the most important performance indicator. Therefore, it should be compulsory product certification through the national CCC.
2. Air volume: Generally speaking, the larger the air volume value, the faster and timely the exhaustion of the kitchen. At the rated voltage and rated frequency, the range hood is operated at the highest speed. In a specific test device, when the static pressure value is zero, the corresponding exhaust air volume is not less than 7m3/min. Therefore, when we select a range hood, when other indicators are good, we should try to choose a large amount of wind. By the way, the amount of wind is not how big it is to design, it is subject to many factors. At present, the exhaust volume of the market reaches 14m3/min, which is already very good.
3. Wind pressure: The greater the wind pressure value, the stronger the anti-winding ability of the range hood. At the rated voltage and rated frequency, the range hood is operated at the highest speed. In a specific test device, the static pressure should be no less than 80Pa when the air volume is 7m3/min. Wind pressure is an important technical indicator to measure the performance of the range hood. If the exhaust pipe is long or connected to the public flue, due to the large loss of exhaust pressure, a larger wind pressure is required to ensure that the flue 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.
4. Noise: Noise is also an important technical indicator for measuring the performance of the range hood. It refers to the A sound power level measured at the highest speed and rated speed at the rated voltage and rated frequency. The state stipulates that the value of this indicator is not more than 74dB. For this indicator, the noise is of course as low as possible.
5. Odor reduction: The ratio of the difference between the maximum odor concentration of the laboratory and the maximum odor concentration under the working condition of the range hood to the maximum odor concentration of the laboratory under the specified experimental conditions. Intuitive feeling, the bigger the indicator value, the better, which means the better the exhaust smoke effect.
Pumping smoke machine buying tips:
Now you should be very clear, what kind of range hood is a superior range hood! You will find that the suction hood with stronger suction and lower noise can truly satisfy your pursuit of perfect life. Some manufacturers' shopping guides may tell you how much the power of their range hoods is, and the corresponding suction is also very large.
Here I would like to remind you that it is very simple to increase the power of the range hood, as long as you use a high-power motor. However, the use of high-power motors does not mean better smoke extraction, because there are many factors that affect smoke exhaust, and the use of high-power motors often leads to high noise.
In addition to the power of the motor, in addition to the power of the motor, there are the speed and performance of the motor, the design structure of the worm wheel, the design of the duct and the structural design of the exhaust chamber. A true range hood should be The above-mentioned various factors achieve the best balance of the combination, not just a certain performance improvement.
I believe that everyone has already learned how to choose a good range hood. What are the conditions for a range hood? If you want to know more about decoration, please continue to pay attention to the decoration home network.
