How to choose a range hood? The range hood is mainly used to take away the oil fume from the kitchen and is a very important household appliance. In order to ensure the air quality in the kitchen, many people are equipped with range hoods. Let's take a look at how to choose a range hood and related information.

How to choose a range hood 1 1. How to choose a range hood?

1, suitable air volume is the basis of a good range hood.

Air volume refers to the smoke exhaust speed of range hood. For a range hood, air volume is the most basic index. The greater the air volume, the better the smoke exhaust effect, but the greater the corresponding noise. When many people choose home range hoods, they blindly choose range hoods with large air volume, and often buy products with exhaust air volume as high as 30m/ min. I don't know that many of these products are used in the kitchens of small hotels, and the noise and power consumption are very high.

2. Wind pressure intensity and air duct design should not be underestimated.

If the range hood has air volume, it must have reasonable air pressure and air duct design, otherwise it can only suck the smoke in but not exhaust it cleanly, or it will be inefficient because of unreasonable air duct design. Generally speaking, under the same efficiency, the higher the wind pressure, the better. For high-rise families, it is recommended to choose a range hood with a wind pressure of not less than 300Pa. For families with low floors and close to the flue, the wind pressure of the range hood should not be less than 240Pa.

3. Noise is a kind of pollution that can't be ignored.

The range hood itself can eliminate oil smoke pollution, but it will produce new noise pollution. Noise has no less influence on people's health than lampblack. People who are noisy for a long time will be agitated and even feel sick and dizzy. The noise generated by range hoods is naturally as small as possible. If you want to talk to your family while cooking, the noise generated by the range hood should be at least lower than 60 decibels, while the noise generated by the range hood is higher than 70 decibels, which is basically equivalent to being in a downtown area, so you have to shout loudly.

2. What kinds of range hoods are there?

1, side-suction range hood. The working efficiency is relatively high, the oil fume can be taken away in the shortest time, and the oil fume can be purified at the same time, so that the polluting oil fume can not be directly discharged to the outside, which is more environmentally friendly.

2. Top suction range hood. The lampblack will be discharged from the top of the range hood, and the density of lampblack will be smaller than that of air, so it will move upward. Then this style of range hood conforms to the movement law of oil smoke, and its smoke exhaust effect will be very good. At the same time, this range hood is not easy to leave dirt after long-term use, and it will be more convenient to clean.

3. Downdraft range hood. It will not only suck out oil smoke at a higher speed, but also will not emit hot air when it is used, so it will be more comfortable when it is used. It is worth mentioning that its operation will not produce noise, and the mute effect is very good.

It can be seen that there are many factors to consider when purchasing a range hood. For example, the air volume refers to the smoke exhaust speed of the range hood. For a range hood, air volume is the most basic index. The greater the air volume, the better the smoke exhaust effect, but the greater the corresponding noise. It is suggested that people must fully consider their own needs before buying.

How to choose a range hood 2? Tips for buying range hoods 1: Look at the appearance and style of range hoods.

Appearance style of range hood

At present, the mainstream range hoods on the market are mainly Chinese and European.

Chinese style: Chinese-style range hood has a deep smoke collecting cavity and good smoke collecting effect, which is more suitable for frying and cooking environment in China. But the main disadvantage is that the appearance is too heavy and not beautiful enough.

European-style: European-style range hood looks fashionable. The obvious disadvantage is that when cooking, it will block the line of sight, kowtow easily, and it is difficult and inconvenient to clean.

Tips for buying a range hood: Look at the shell material of the range hood.

Shell material of range hood

At present, the shell of range hood on the market is mainly made of two materials, one is stainless steel (note that some manufacturers use ferroalloy, and the surface is covered by spraying or so-called baking paint process, so pay special attention when purchasing. One is tempered glass or the combination of two materials, and the cleanliness of tempered glass is greater than that of stainless steel. If your kitchen is small, I suggest you choose toughened glass with good permeability, because it won't take up too much space visually. ?

Tips for buying a range hood 3: Look at the performance parameters of the range hood.

Performance parameters of range hood

Safety performance is the first, and the range hood must pass the national CCC compulsory product *. When we choose a range hood, we should try to choose the one with large air volume and wind pressure when other indicators are good. At present, the exhaust air volume on the market is 14m3/min, which is very good. There is also a good ability to worry about oil. Of course, low noise, easy cleaning and after-sales service should also be considered.

How to choose a range hood 3? Classification of range hoods

1, Chinese range hoods are mainly divided into old-fashioned shallow-suction deep range hoods, especially shallow range hoods. It is an ordinary exhaust fan, which directly discharges the oil fume to the outside. The biggest problem of deep range hood is that it takes up space, is noisy, is easy to touch, can't clean the dripping lampblack, has a short service life, is inconvenient to clean and pollutes the environment. Numerous brands

2. It is a European-style range hood, which uses multi-layer oil filter screen to filter {5-7 layers}, so as to increase the motor power and achieve the best effect. Generally, the power is above 300 watts. Features: beautiful appearance, expensive price and power consumption. It is inconvenient to clean the oil net, and it is easy to encounter oil dripping. Represented by the boss Tai Fang.

3. Side-suction fume purifier. Based on the design of aerodynamics and fluid mechanics, the principle of separating oil fume by oil fume separation plate and then discharging clean air is adopted. It is characterized by good smoke exhaust effect, and the smoke exhaust effect is above 99%. Don't drop oil, don't meet, hide in the cupboard and integrate with the cupboard, and don't take up space. The motor is oil-free, with long service life and convenient cleaning. Power saving is generally 160 watts. The oil fume does not pass through the breathing area, which ensures the health of housewives. The discharged clean air will not pollute the environment.

4. Water curtain type new range hood. The water curtain range hood adopts the washing absorption method. While absorbing and discharging the oil fume, the atomized water solution and oil mist are automatically emulsified and saponified by using the aqueous solution with detergent, and most harmful substances generated during fuel combustion and oil fume generated during cooking are neutralized and purified by the aqueous solution. The oil purifier will automatically give an alarm to remind the user to change the detergent. Mainly used in kitchens of large hotels.

Secondly, select a few points for attention.

1. There are many factors to consider when buying a range hood. Generally speaking, the certified range hood is more reliable in safety and quality.

2. The air volume, fan power and noise of the range hood should be considered comprehensively. The greater the air volume and fan power, the better. Under the premise of achieving the same net extraction rate, the smaller the fan power and air volume, the better the mute effect can be achieved. As for noise, the national standard stipulates that the noise of range hoods should not exceed 65 to 68 decibels. In this sense, families who usually like to cook and stir-fry with fire, it is best to avoid buying shallow-cover flat plates and ultra-thin range hoods with low smoke extraction rate.

3, practical do not choose European: big and heavy.

4, don't LCD: expensive and easy to break.

5. Choose traditional mechanical switch instead of touch switch: traditional switch has low maintenance rate and high substitutability.

6, panel material, glass scrubbing is more convenient, stainless steel, but heavier.

7, don't automatic cleaning function, there are not many practical functions.

8. The diameter of the air outlet is directly proportional to the exhaust air volume, and the larger the outlet, the better.

9. Convenient cleaning is also important. Many consumers reported that the smoke exhaust effect and noise of the newly bought range hood were normal when it first started working, but after working for a period of time, the noise increased and the exhaust air volume decreased. This is mainly the result of oil accumulation in the turbine blades of the range hood fan, which destroys the dynamic balance. Therefore, the cleaning of range hoods is very important in the daily maintenance after purchase.

When shopping, consumers should pay special attention to those models where lesbians can easily remove the net cover and fan turbine blades without using any special tools. At the same time, we should also carefully observe that there should be no seams and grooves on one side of the hood of the range hood, so that it is more thorough and convenient to clean.

10, avoid buying miscellaneous brands and products produced by small factories, and ensure product quality. The industrial and commercial department pointed out that the enterprise that produces the whole range hood must obtain the production license from the quality and technical supervision department before it can produce.

1 1. Imported range hoods are not better than domestic ones. Imported range hoods are designed according to the eating habits of westerners. Too many oil nets are inconvenient to clean. The motor has high power and consumes electricity.

Selection of range hood in open kitchen

The smoke exhaust effect of the traditional range hood is not ideal, and it is smoky when cooking, sweating like rain and smoky. Go into the kitchen once and change clothes twice. The range hood is installed above the head, which often touches and drips oil. When the oil fume is discharged, it will inevitably smell in the nose, which will bring hidden dangers to health. It is extremely inconvenient to disassemble and clean regularly.

1, the soot of the fan body is fouled, and the running noise becomes louder, resulting in irritability. Kitchen tiles should be cleaned every day, and cabinets and stoves will become greasy within a month. The design of open kitchen and the effect of range hood can't be balanced.

2. The traditional range hood directly exhausts the fume gas inhaled by the machine to the outside (or enjoys the flue), which seriously pollutes the outdoor air and causes secondary pollution. Side-suction range hood, with high-efficiency oil fume removal effect, makes the whole kitchen no longer have oil fume to escape, and no longer has to worry about the pollution of oil fume to cabinets and walls. It is an ideal choice for an open kitchen. Low-position wall-mounted installation, not afraid of dripping oil. Smoke is absorbed laterally, without passing through the nose and mouth, completely protecting health. The separation of oil fume keeps the interior of the machine cavity clean, and it is free of disassembly and washing. Unique thorough air intake, using advanced aerodynamic principles, so that oil smoke, waste gas and odor are sucked away as soon as they are produced, and the suction and discharge are more thorough. The original oil-gas complete separation technology can separate oil smoke and discharge fresh air to the outside, which is more environmentally friendly to nature.

Side range hoods are more suitable for open kitchens. For ordinary kitchens, European range hoods can completely absorb oil fumes, so it is best to choose side-suction range hoods for open kitchens.
