Exhaust hood capable of automatically opening and closing air deflectors

Abstract

The invention discloses an exhaust hood capable of automatically opening and closing air deflectors. The exhaust hood mainly comprises an exhaust fume collecting hood assembly, a host shell assembly and a fan assembly. The host shell assembly is located on the upper part of the exhaust fume collecting hood assembly; the fan assembly is located in the host shell assembly; the slidable air deflectors are arranged on the exhaust fume collecting hood assembly, and is connected with a drive device; an air inlet is formed in the exhaust fume collecting hood assembly; the drive device drives the airdeflectors to slide between a first position for shielding the air inlet and a second position for opening the air inlet. According to the exhaust hood provided by the invention, the two air deflectors are arranged under the exhaust hood and correspond to independent movement systems; when a cooking utensil on one side is used, the air deflector corresponding to the cooking utensil can be opened,so that the occurrence of the phenomenon that a lampblack collecting effect is influenced by turbulence caused by hedge of an air flow on the other side can be prevented, a lampblack escape phenomenonduring a rising process is reduced, and the lampblack collecting effect is improved maximally; when cooking utensils on two sides are used at the same time, both the left air deflector and the rightair deflector can be opened.

Description

technical field [0001] The invention relates to a range hood structure, in particular to a range hood with an automatic switch of a wind guide plate. Background technique [0002] In the prior art, the air intake area of ​​the European-style range hood has multiple air intake methods, one of which is to add an air deflector to the lower part of the middle part of the air intake, and the air intake area bypasses around the air deflector before entering The air inlet; its negative pressure area is around the range hood. There are two problems with this method: 1: Reduce the negative pressure area of ​​the range hood; 2: The oil fume rises and absorbs to the deflector and then winds into the range hood The filter screen of the air inlet of the range hood; with the increase in the number of uses of the range hood, a large number of oil droplets will form on the deflector, which greatly increases the risk of oil dripping; and the deflector is a whole part, which is difficult to c...
