Advantages and disadvantages analysis of three main range hoods

Kitchen is the weakest link of family hygiene, and the biggest problem is air pollution. A large amount of oil is deposited inside the hood, which is easy to produce carcinogens such as tar when heated and volatilized. After being absorbed by the human body, it is easy to cause lung diseases and even lung cancer, so a good range hood is definitely a necessary appliance for every family.

There are many kinds of range hoods. According to the working mode and installation location, there are mainly top suction type and side suction type, and there is also a downward suction type (also called upper row, side row and lower row), which is rare in the market.

At present, the mainstream range hoods in stores are generally divided into top suction type (European and Chinese) and near suction type (side suction type) according to their structural types.

Among them, Chinese style can be divided into lightness and simplicity. Simple types can be divided into deep types and sub-deep types. As far as the number of motors and wind wheels is concerned, it can be divided into two machines and one machine (that is, double cylinder and single cylinder). Top-suction European range hoods generally have three shapes: tower type, T type and arc type.

However, with the increasing demand of consumers for kitchen appliances, simple functional requirements are not the only factor for consumers to buy, and its shape design has also become the focus of young people's purchase. The near-suction range hood has a unique shape and a relatively low installation height, which occupied a large sales share in 2009. What's the difference between these three types of range hoods? What are their advantages and disadvantages? The author gives you a brief introduction.

Advantages and disadvantages analysis of three main range hoods

Smoke exhaust effect: It belongs to deep breathing smoke machine, and generally adopts high-power motor, with large smoke collection cavity and large turbine. It is a direct suction type, which can gather the rising smoke together first and then exhaust it through the oil net, which has good smoke exhaust effect and is more suitable for China families who often cook and cook.

Energy saving effect: China range hood with power 168 is even better than European range hood with power 200, so the lowest power in Europe is around 200. In contrast, the range hoods in China are more energy-efficient than those in Europe.

Installation requirements: From the installation position, it basically belongs to the "ceiling-mounted" range hood, with the size of 700 mm-750 mm, which is suitable for families with small kitchens, and has relatively small requirements for cabinets and appropriate size.

Price problem: the cost of production materials is low, the manufacturing process is relatively simple and the price is moderate.

Technical index: The wind pressure corresponding to powerful range hoods in China is generally 350 Pa, and that of ordinary range hoods in China is generally 280 Pa. The national 1999 approved that the wind pressure of the range hood should not be less than 80 Pa, and no new standard has been issued at present.

Disadvantages: unsightly appearance, loud noise, easy to touch, dripping oil, unclean oil fume, non-separation of oil fume, some pollution to the surrounding environment, inconvenient cleaning, short service life, and most switches are basically mechanical switches, which is heavy!

Soot absorption effect: The principle is that it rises circularly, and the single turbine, small smoke collecting bin, non-smoke collecting bin and multi-layer dense mesh plates are superimposed. The smoke absorption effect is worse than that of the medium-sized machine, but the smoke separation, low noise, energy saving and environmental protection are the main popular trends of the current machine.

Appearance: the appearance is really beautiful and fashionable, and there are many kinds of fabrics to choose from. The switch can be selected from two styles: mechanical switch and touch switch, which increases the highlight of the kitchen and is novel in style.

Installation requirements: From the installation position, it basically belongs to the "ceiling-mounted" range hood, generally 800 mm-900 mm in size. You can choose an open kitchen or a larger kitchen, which can match most cabinets and basically belongs to the "ceiling-mounted" range hood.

Price: The production process is complicated and the material cost increases, so the price is higher than that of China cigarette maker.

Disadvantages: The smoke removal effect of European range hoods is not as good as that of China, and the smoke absorption rate is not high and the power is not small.

Smoke exhaust effect: the oil absorption area is large, which is close to lampblack. Aerodynamics and fluid mechanics are mostly used for design. The principle that the oil fume is separated by the oil fume separation plate first, and then the clean air is discharged. The discharged clean air does not pollute the environment, does not drip oil, and does not meet the requirements. The oil fume extraction effect is good, and the oil fume absorption rate is over 99%. The motor has long service life and convenient cleaning, and is especially suitable for Chinese kitchens.

Installation requirements: Side-suction range hood completely breaks through the design method of traditional ceiling range hood. Through the wall-mounted installation of side air intake and unique core technology, the oil fume absorption effect is higher than that of the traditional range hood. When installing, there are certain requirements for the cabinet, which is hidden in the cabinet and integrated with the cabinet, occupying no space, and the oil smoke does not pass through the breathing area to ensure the health of housewives.

Price problem: the production process is complicated and the material cost increases, so the price is higher than that of CEIBS;

Disadvantages: The noise is generally loud.

When choosing a range hood, the key technical indicators are: wind pressure, air volume and noise, which must be paid attention to when purchasing. Due to technical limitations, the wind pressure is mostly around 230 Pa to 280 Pa, the air volume is generally between 12 cubic meter and 15 cubic meter, and the noise should be between 52 dB and 65 dB. If the flue gas is discharged to the public flue, the wind pressure is high.

Comprehensive consideration: all kinds of range hoods have their own advantages and disadvantages, and they should be considered according to their actual situation when choosing! Just as there is nothing perfect in the world, when we choose a product, we should accept its shortcomings according to our actual situation, so that we will be satisfied with the product we choose. Perhaps in the near future, with the continuous progress of technology, our electrical equipment will be more perfect!
