Range hood

Abstract

The invention discloses a range hood, belongs to the technical field of household appliances, and is designed for solving the problems that oil smoke in an existing range hood is easy to diffuse and the like. The range hood provided by the invention comprises a box body, wherein a smoke exhaust channel is formed in the box body; the exhaust fume collecting hood is provided with an air inlet, and the air inlet is connected to the exhaust fume discharging channel through the exhaust fume collecting channel; and the rectifying plate is arranged between the smoke discharging channel and the smoke collecting channel, and the rectifying plate is configured to be capable of limiting the flowing path of the oil smoke. According to the range hood provided by the invention, the space where oil fume can reach when flowing in the range hood can be reduced, the diffusion area of the oil fume is reduced, the risk of oil stain permeation is reduced, and the problems that parts in the range hood are instable in work and short in service life due to permeation of the oil fume are solved. The rectifying plate realizes rectification of fluid in the range hood, the disorder degree of the fluid in the range hood is reduced, the oil smoke discharging efficiency is higher, the impact of the fluid on the interior of the range hood is smaller, and the noise is lower.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a range hood. Background technique [0002] A range hood is a household appliance used to discharge indoor oil fumes to the outdoors. Its working principle is as follows: a fume exhaust channel is formed in the shell of the range hood, and a fan is arranged in the fume exhaust channel. [0003] In order to collect the oil fume in the room well, the fume extractor is usually designed with a fume collecting hood, and the fume collecting hood is provided with an air inlet. In the existing range hood, the area between the port of the fume exhaust channel and the port of the air duct in the fume collecting hood is relatively open, and the range of movement of the fume is large, which causes the fume to diffuse in the fume extractor, and the risk of oil penetration is high, reducing the risk of oil pollution. The working stability of the components in the range hood shor...

AI Technical Summary

Problems solved by technology

In the existing range hood, the area between the port of the smoke exhaust channel and the port of the air duct in the fume collecting hood is relatively open, and the range of activity of the oil fume is large, causing the oil fume to diffuse in the range hood, and the risk of oil pollution penetration is high, which reduces the The working stability of the parts in the range hood shortens the service life of these parts; moreover, the oil fume tends to flow in disorder in this area, and the efficiency of oil fume exhaust is low
