Range hood shape development "trilogy"
The advent of range hoods, enable people from chuiyanniaoniao "ancient poetic" coming out, so that the kitchen revolution really a step forward. After ten years of development updates, cooker hoods mainly has three stages: smoke tobacco, European-style and side-suction.
Chinese tobacco into shallow and deep-two. The shallow suction hood is the common exhaust fan, has gradually been eliminated by the times. Deep suction machine on the basis of the original has been greatly improved, but it looks boring, look cumbersome enough fashion, it is difficult to meet consumers ' demands.
European-style look and fashion, luxury, is many people's favorite. Use multiple layers of oil NET filtering, its general power in more than 200 watts, but universal suction is not enough, for like: oil speculation in the Chinese family to seem too polite.
Side suction gas turbine is now the most keenly by the strong suction range hood, it does not meet. But the side suction smoke opportunity loss cooking space, besides loss of heat shortcomings on the side of the impact of the type smoke is very large, because its too close to the suction caused part of the air supply, weak, resulting in the furnace combustion is not sufficient, so consumers always have reflected the side suction machine, its gas or natural gas usage.
Million and the double-blade "industry broken Board
The largest manufacturer of gas appliances--million and, in order to meet consumer demand for packaged integration kitchen electrical appliances will smoke ... include its important gas appliances support products. Million and President Lu Chukotka Cannon said that smoke the most critical indicators, that is the net rate of absorption of cooking, and various domestic cooker hoods, mostly focus on appearance and concepts, as the tobacco industry's rising star, million and is to play it in the "technology innovation" consistent advantage in fume suction net rate this key indicators on the breakthrough.
2007 national day, and researchers in Nanjing Mall market mapping surveys, see a display of a certain brand of single-wheel widening of smoking machine, it through the middle of the wind wheel with a stiffened to prevent distortion of the wind wheel, increases the rotor area, improving the air suction rate. The presence of a researchers suddenly said: "with a rebar is to put a wind wheel into two wind wheel, the motor output has not changed, the increased rate of aspirating smoke machine. If we can put the wind wheel into two wind wheel, do bigger point, and then arranged for both ends of the shaft, is not the wind wheel than this smoke machine width longer? "researchers took this idea started the design of experiments, and the double-rotor" was born from this range hood.
Million and the double-blade "series range hood takes two independent wind wheel, the total number of valid width achieve 210mm, than a single blade width 60%; wind tank width up to 271mm, than ordinary hood 172mm width 57 per cent, smoking, smoking up to 40 percent. The original market tobacco 13m3/min of suction rate increased to 19m3/min. Research Assistant to the President of China electrical appliance-Chen Zhang ya think, 000 and the two-blade "innovative energy-saving technology, will certainly cause industry pattern of re-shuffling, will usher in smoke ..." the double blade era ".
Who mastered the techniques, who is leading the market
China is currently extending the prototype of the hood are mooring to commodities, is the imitation of Germany, Italy, Japan and other countries of the models, the industry's innovation capacity is weak, slow technology upgrading. Because foreign cooking habits and not much different, soot, smoke suction in net rate technology as not big, but domestic tobacco companies are indulging in foreign models appearance of imitation. But the million-and-tilt "both a stylish, upscale European appearance, but also solves the Chinese families: fried and fumes from big problems.
Range hood homogeneity serious is causing the industry increasingly intense competition between one of the main reasons why. The history of the hood, "clone" is a homogenous market range hood. So the only truly grasp the core technology to produce suitable for China's hood in the fierce market trip out to win the advantage.
