A rectification acceleration disk structure for a range hood

Abstract

The invention discloses a rectification acceleration disk structure for a range hood, which comprises a rectification plate arranged facing the air inlet of the smoke collection hood of the range hood, and is characterized in that the rectification plate is provided with a The acceleration disc is formed with at least two acceleration passages for accelerating the oil fume, the acceleration passages extend from the periphery of the rectifying plate toward the center, and the cross-sectional area gradually decreases. The rectification acceleration plate structure is formed by adding an acceleration disc on the side of the rectification plate opposite to the fume collection hood, forming a radially reduced oil fume acceleration channel, which shunts and absorbs the oil fume, and accelerates the diameter of the rectification plate. A stable negative pressure ring area is formed, and the rising oil fume is dynamically and continuously collected and then sucked into the fan at an accelerated rate, so that the range hood can achieve the best and largest surrounding stable smoke collection effect, and can reduce the kitchen odor. to minimum.

Description

technical field [0001] The invention relates to a range hood, in particular to a rectification acceleration plate structure for the range hood. Background technique [0002] A rigid indicator of a clean kitchen environment is the odor level, which can be used to measure the smoke collection effect of the range hood. Existing commonly used range hoods are usually set to form a concave cavity in the fume collecting hood, and the fume collecting hood is provided with an air inlet and a filter screen, and the oil fume absorbed by the fan enters from the air inlet after passing through the filter screen. This method is intuitive and effective for the range hood. However, in the process of absorbing the range hood, it not only absorbs too much oil and seasoning in the pot, increases the loss of heat energy, but also increases the burden of filtering oil and accumulating dirt on the range hood. [0003] In order to overcome the above-mentioned disadvantages and improve the smoke c...

Problems solved by technology

However, due to the large difference in the distance between the surroundings of the smoke guide plate and the smoke collecting hood, the section of the oil fume passage is positively uncertain; moreover, when the oil fume flow enters from the surroundings of the smoke guide plate, it spreads immediately, and the static The pressure rises suddenly, which makes the effect of negative pressure around the smoke deflector extremely unstable
