How to choose the perfect range hood?

Kitchen cooker oil fume machine choose well, cooking less oil fume!Buy qualified and cost-effective kitchen cookware with hoods that make us feel happy and cook better! An excellent kitchen cooker hood needs to have good smoke removal effect, low noise, and easy to clean.Below I will analyze in detail how to buy cookware hoods from these three aspects.

1. Working principle Cookware Hood

The basic working process of the hood is: the power supply drives the motor to operate, and the motor drives the rotor to rotate.A negative pressure zone gas furnace is formed above.The oil mist into the cooker is filtered and separated by the hood, condensed into droplets into the oil cup, and the smoke is discharged outside.

2.air volume indicator cookware hood

Airflow is an important indicator before recommending cookware hoods.Units are cubic meters per minute.Unilaterally speaking, the larger the exhaust volume, the faster the kitchen smoke is discharged, but not the bigger the better.Too much air will take away a lot of heat.This will affect the normal working gas stove!

How to choose fan air volume cookware according to your own hood kitchen?

The flow rate of the range hood is: <14m3/min, 14-15m3/min, 15-16m3/min, >17m3/min.The specific air volume selection should be determined according to the kitchen area, cooking habits, and flue conditions.

The average family kitchen has an area of 3-5 square meters, 5-7 square meters, 7-9 square meters and more than 10 square meters.The kitchen is also open and closed.K itchy area below 10 square meters, choose 15m3/min as the best, t his kitchen has more than 10 square meters should be selected than....better than 17 cubic meters per minute.

In general, 15 cubic meters per minute is enough to meet the family's cooking habits. If the amount of stir-fried vegetables is more, you can choose >17m3/min exhaust air volume. In addition, the choice of exhaust air volume is determined according to the length of the flue.The longer the flue, the harder it is to exhaust.You can choose high air volume >17m3/min or buy cookware hood with self-boosting function.

Many people say that the hood is good as long as the air volume is large.In fact, this is a misconception, or not entirely correct.If you want the hood to smoothly drain the kitchen oil smoke, you need air volume and air pressure to complete.时间hey are indispensable. If the air volume is large and the blast pressure is not enough or the blast pressure is too large, but the air volume is too small, the cooker hood will not has an ideal smoke exhaust effect.

3. Blast pressure index of cooker hood

As we talked about above, only large air volume cannot discharge oil smoke, and blast pressure is needed to assist. Blast pressure refers to the static pressure value when the exhaust air volume reaches 7m³/min (these terms don’t need to be understood too much), just remember that the larger the static pressure value, the stronger the ability to resist returning smoke.

I think some friends have encountered such a situation, that the cooking fume of other people’s home enters their own kitchen, which means that the blast pressure of the cooker hood you bought is low, but there is no need to worry too much about this problem, because now on the market most of cooker hoods usually have a blast pressure above 300Pa, which is enough for common building families.

Some friends may ask how much blast pressure cooker hood I need to live on the XX floor. Here is a simple reference formula for everyone:

Total number of floors-floor to live = reference value

And then refer to the blast pressure in the figure below:

Total number of floors-floor to live = reference value

reference value

Corresponding blast pressure









For example, there are 28 floors in total, you live on the 20th floors, the reference value: 28-20=8, just choose the blast pressure above 300Pa compared with the above table.

4. Noise index of cooker hood

When we buy a cooker hood, the noise is also we must pay special attention to, excessive noise will make you feel very uncomfortable when cooking, and it is not good to spend money to suffer!

If the noise of the cooker hood below 65dB, it is good, but we have to understand two different concepts, sound pressure level and sound power level. There is no need to go into what it means, as long as you know that sound power level is equal to sound pressure level + 14dB, knowing this will prevent you from being fooled by some "bad" sales when you buy a cooker hood!

5. Cleaning index of range hood

When buying a kitchen range hood, you must not only pay attention to greater suction power but also have to concern about the cleaning issue. Related data shows that more than 1/3 of after-sales problems are caused by cleaning.

The cooker hood cleaning mainly includes the whole machine cleaning, external cleaning and internal cleaning. Nowadays, many cooker hoods have automatic cleaning function, but the price is more expensive. If you have a sufficient budget, buying one with an automatic cleaning function is the best choice.

These are the issues to be considered when purchasing a range hood.I hope you will be able to buy your favorite fan after reading this article.
