All kinds of hoods have their advantages and disadvantages. When we choose, we should consider according to our actual situation and choose the one that suits us best. Here, the author talks about the advantages and disadvantages of Chinese, European and side hoods.
European hood features:
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, so the smoke absorption effect is worse than that of medium-sized machines, but the separation of oil smoke, low noise, energy saving and environmental protection are the main popular trends of smoke machines now;
Appearance: the appearance is really beautiful and fashionable, and there are many kinds of fabrics to choose from. The switch can have mechanical switch and touch switch styles to choose from, 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: In fact, 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.
Characteristics of side suction range hood;
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 of separating oil fume with oil fume separation plate first and then discharging clean air is adopted. The discharged clean air does not pollute the environment, does not drip oil and does not meet each other. The lampblack extraction effect is good, and the lampblack absorption rate is above 99% (in fact, many of them can't reach it). The motor has long service life, non-stick oil and convenient cleaning, which is especially suitable for China kitchen.
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!
Characteristics of Chinese style hood:
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, Chinese range hoods are more energy-efficient than European range hoods.
Installation requirements: from the installation position, it basically belongs to the "ceiling-mounted" range hood, with a size of 700 mm-750 mm, which is suitable for families with small kitchens, with 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!
