Problems solved by technology

Although the range hood has been popularized in Chinese kitchens, its lack of functions exists in reality: 1. Can't clean the lampblack; 2. Loud noise; 3. High energy consumption, etc.
Eliminating oil fume requires original technology, and the problem of oil fume pollution cannot be completely solved by import or imitation

Embodiment 1

[0038] Embodiment 1: The working principle of the present invention is: cooking fume is the fluid formed after the oil is heated and vaporized, and the working medium of the range hood is not pure oil fume, and its main components are air plus exhaust gas (comprising water vapor, mist Grease, lampblack and the exhaust gas formed by the combustion of stove fuel), the function of the range hood is to remove the exhaust gas. Exhaust gas is a fluid that diffuses and mixes in the air immediately after it is generated. The longer the diffusion time and the greater the movement stroke, the larger the volume that needs to be discharged. Through testing, the absolute amount of exhaust gas produced by general family Chinese food cooking does not exceed 0.4m on average. 3 / min; After the exhaust gas is mixed with air, the exhaust gas origin (zero boundary point) is taken as the outlet plane of the cooker, and when there is no influence of side wind, the minimum flow rates required for ex...

Embodiment 2

[0039] Embodiment 2: In this embodiment, only one oil suction fan is provided, and the oil suction fan and the oil exhaust fan are directly connected through an air duct, and no branch air duct is required. Other features are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to a calculus power low-carbon range hood which is different from the suction and discharge power (fan) integrated system of the common range hood; and the power of the calculus power low-carbon range hood is independent oil smoke suction power (an oil smoke suction fan) and oil smoke exhaust power (an oil smoke exhaust fan), and the oil smoke suction fan and the oil smoke exhaust fan are connected in a common flue system in series for combined working. The air suction port of the oil smoke suction fan is furthest close to an oil smoke generating point, and suctions the oil smoke thoroughly before the oil smoke is diffused; and the oil smoke exhaust fan at a flue outlet exhausts the oil smoke in a flue, and prevents the influence of outdoor air flowing and outdoor concentrated flue pressure on the exhaust of the oil smoke. The power energy consumption of the calculus power low-carbon range hood is only 24% of that of the common range hood, so that the calculus power low-carbon range hood is a genuine low-carbon range hood. In the invention, the working noise is lower than 40 decibel and is only a half of the national standard noise of the common range hood, and the international difficulty of high noise of the range hood is successfully solved. In addition, due to a non-return, windproof and fireproof system, the operation of the range hood under the high-efficiency and safe state is guaranteed.

Description

technical field [0001] The patent of the present invention relates to the field of oil fume treatment produced during cooking in the kitchen, in particular, it involves the use of fluid calculus equations to calculate and analyze the mechanism of oil fume, the mixing process of oil fume and air and their movement forms in the flue, and select a miniature axial flow fan to pass through The same air duct works and controls in parallel and in series to achieve thorough, efficient, quiet and safe suction and exhaust of oil fume. Background technique [0002] As a special device for absorbing and exhausting oil fume, the range hood should be designed based on the research on the occurrence and movement mechanism of oil fume. Yet the range hood technology on the market directly comes from or improves on the ventilating device (English name: COOKERHOOD) of Western-style food kitchen at present. The inventor has conducted more than ten years of research on COOKERHOOD and the mechan...
