Near-inhaling type kitchen ventilator with centralized exhaust inlet

Abstract

The invention relates to a near-inhaling type kitchen ventilator with an centralized exhaust inlet. The near-inhaling type kitchen ventilator consists of an axial flow fan case and is characterized in that a straight pipe is rotatably sleeved with an upright round pipe smoke exhausting hole of the axial flow fan case through a round pipe hole in the upper end of the straight pipe, the central axis of the straight pipe below the sleeving part forms an included angle with the perpendicular line and is sleeved with another smaller pipe, and the sleeved pipes can longitudinally slide, wherein the straight pipe below the sleeving part has a same shape as another cross section. Thus, an air pipe hole can move in all directions and can be conveniently regulated to an optimal smoke exhausting position to effectively exhaust the smoke. The near-inhaling type kitchen ventilator has the beneficial effects that the exhaust inlet is formed in a centralized manner and can reach the optimal smoke exhausting position, and the smoke exhausting efficiency is high.

Description

technical field [0001] The invention relates to a near-suction range hood, in particular to a concentrated tuyere near-suction range hood. Background technique [0002] There are two types of suction outlets for commercially available near-suction range hoods: inline and dispersed. Although the forms are different, they have the same characteristics: the air suction port is scattered, and it is outside the pot mouth, and the average distance from the pot mouth is relatively long. Experiments have proved that the centralized tuyere located at a certain height above the pot mouth can make the air around the pot mouth quickly flow to the tuyere, forming a strong air curtain, which can effectively prevent the oil fume from diffusing and escaping. However, the existing form of dispersing tuyere does not have this ability, let alone absorb all the diffused oil fume. Moreover, the distance between the tuyere and the mouth of the pot means that a considerable proportion of air wit...

AI Technical Summary

Problems solved by technology

However, the existing form of dispersing tuyere does not have this ability, and it cannot absorb all the diffused oil fumes.

And the farther the tuyere from the pot mouth means that a considerable proportion of air without oil fume is inhaled while the oil fume is inhaled, correspondingly reducing the inhalation of oil fume, and the smoking efficiency is low
