Range hood with automatic smoke hood adjustment function

Abstract

The invention provides a range hood with an automatic smoke hood adjustment function. The range hood structurally comprises a range hood top hood, an exhaust fan, a rotatable smoke hood, protective wings, an oil smoke pipeline, a fresh air exchange axial flow fan, a fresh air exchange pipeline and connecting rods, wherein the exhaust fan is fixed to the inner side wall of the range hood top hood,the exhaust fan is connected with an oil smoke outlet in the top of the range hood top hood by virtue of the oil smoke pipeline, the fresh air exchange axial flow fan is arranged in the range hood tophood and is connected with a fresh air exchange port in the top of the range hood top hood by virtue of the fresh air exchange pipeline, the rotatable smoke hood is connected with the range hood tophood by virtue of the connecting rods on both sides, the two protective wings are symmetrically arranged on the left and right sides of the bottom surface respectively, and motors which are used for controlling the protective wings to extend and side exhaust fans are arranged in the protective wings. The range hood has the advantages that (1) an automatic microcomputer technique is adopted to realize automatic control, so that the efficiency is improved; (2) a fresh air exchange system is adopted, so that the cooking environment is improved; and (3) an automatic smoke hood exhaust adjustment system is adopted, so that the maximum exhaust efficiency is guaranteed.

Description

technical field [0001] The invention relates to a range hood for automatically adjusting a smoke hood, and belongs to the technical field of range hoods. Background technique [0002] Existing household range hoods mainly include three types: top suction type, side suction type and back suction type, among which the effect of top suction type is better, followed by side suction type and back suction type. The degassing effect of the range hood is closely related to the suction height, and the closer it is to the stove, the better the degassing effect, but the space required for actual operation limits the design of the suction height and position of the range hood. [0003] In order to reduce the suction height as much as possible, on the basis of the traditional fixed range hood, the partial exhaust range hood adopts a structure with a variable suction height to improve the effect of extracting oil fume. However, this structure is not only complicated in mechanism, but also...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes a range hood that automatically adjusts the fume hood, and its purpose is to overcome the defects that the existing range hood has low suction power and cannot be automatically adjusted according to actual needs, and adopts side suction plus top suction. The exhaust structure can automatically adjust the telescopic angle of the hood and wings according to the concentration of oil fume and the distance between the cook and the stove, so as to absorb all the oil fume and discharge it outside
