Example Embodiment

[0015] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0016] See Figure 1 ~ Figure 3 , A rectifying and accelerating disk structure for a range hood, the range hood used includes a smoke collecting hood 1, and the smoke collecting hood 1 is provided with an air inlet 11, facing the air inlet 11 and spaced apart from the smoke collecting hood 1 There are rectifier plates 2.

[0017] The side of the rectifying plate 2 facing the smoke collecting hood 1 is provided with an accelerating disc 3. The accelerating disc 3 includes a bottom surface 31 and at least one side surface 32 located at the periphery of the bottom surface 31. In this embodiment, there are four side surfaces. The accelerating disk 3 covers the rectifying plate 2 and can be fixed to the rectifying plate 2 by riveting or the like. The bottom surface 31 is opposite to the smoke collecting hood 1 and has a certain gap to form a certain inlet distan...

Abstract

A disclosed rectification acceleration disc structure of a range hood comprises a rectification plate exactly facing to an air inlet of a smoke-collecting cover of the range hood; one side, facing to the smoke-collecting cover, of the rectification plate is provided with an acceleration disc; the acceleration disc comprises at least one side surface, and an acceleration channel for accelerating oil smoke is formed between the side surface and the smoke-collecting cover; and the sectional area of the acceleration channel from bottom to top is gradually reduced. by additionally adding the acceleration disc on the side, facing to the smoke-collecting cover, of the rectification plate, the rectification acceleration disc structure is formed, and the diameter-reducing oil-smoke acceleration channel is formed, oil smoke is divided into flows and is absorbed, and is accelerated in a diameter-reducing way, and a stable negative-pressure annular area is formed at the inner-side circumference of the rectification plate and relatively to the periphery, continuously-rising oil smoke is dynamically continuously gathered and is accelerated and absorbed into a blower fan, so that the range hood reaches the optimum maximal peripheral stable smoke gathering absorbing effect, and kitchen smell is reduced to a lowest density.

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...
