Range hood

Abstract

The invention relates to the technical field of a domestic stove cooking fume removal part, and discloses a range hood. The range hood comprises a fume collection cavity used for collecting oil fume, a diversion channel communicated with the fume collection cavity, and an oil cup used for collecting oil stain, and range hood is characterized in that the bottom of the fume collection cavity is provided with an air inlet; the top of the fume collection cavity is provided with an air outlet; the diversion channel is arranged above the air outlet of the fume collection cavity; the diversion channel comprises a fan component, a volute component and an air outlet component which are arranged on the air outlet of the fume collection cavity and sequentially arranged from bottom to top; and an air inlet of the fan component, an air outlet of the fan component, an air inlet of the volute component, an air outlet of the volute component and the air outlet component form a structure which is vertically through up and down. Compared with the prior art, the range hood provided by the invention has the characteristics of being low in wind resistance, small in packaging size and convenient to clean.

Description

technical field [0001] The invention relates to the technical field of cooking smoke removal components for household stoves, in particular to a range hood with a straight-in and straight-out air duct system. Background technique [0002] A range hood, as the name implies, is a device used to suck kitchen fumes, generally including a motor and a wind wheel. When the range hood is powered on, the motor drives the wind wheel to rotate at a high speed, forming a negative pressure area in a certain space above the stove, sucking the indoor oil fume into the hood, and filtering it through the oil net to perform the first oil fume separation , and then the oil fume enters the inside of the hood air duct, and the oil fume is separated for the second time through the rotation of the turbine. At the same time, the oil fume in the air cabinet is subjected to centrifugal force, and the oil mist condenses into oil droplets, which are collected into the oil cup through the oil circuit ,...

Problems solved by technology

[0004] Moreover, the design of the product structure of the above three types of range hoods all need to support the normal operation of the range hood by adding a box, which makes the range hood larger, which not only increases the production cost of the product, but also makes the product The volume of the packaging increases, and the transportation cost of the product increases during the circulation process

[0005] In addition, range hoods need to be cleaned after being used for a period of time. At present, the automatic cleaning introduced by major manufacturers is a solution to the symptoms, not the root cause. The range hood products that have been used for a long time still need to be cleaned manually.

However, the above three types of range hoods have complex structures, and manual cleaning requires professionals to lift the range hood from the installation state before cleaning, which is extremely inconvenient to operate.
