Description

Comprehensive range hood

Technical Field

The invention relates to the technical field of range hoods, in particular to a comprehensive range hood.

Background

It is reported that: in many big cities in China, complaints of residents about oil smoke pollution of the catering industry account for more than 40 percent of complaints about environmental pollution. Dietary smoke contains many harmful components, many of which are mutagenic and carcinogenic substances. Research shows that cooking fume contains at least more than 200 chemical components. The incidence rate of lung cancer is closely related to the oil fume emission of a kitchen, and if the factor of cooking oil fume is eliminated, the incidence rate of lung cancer can be reduced by half.

The existing smoke exhaust ventilator or smoke exhaust ventilator has the following oil smoke treatment processes: the oil smoke gas enters the air duct of the range hood after passing through the oil screen, the rotation of the turbine separates the oil smoke from the oil smoke gas, the oil smoke in the air cabinet is acted by centrifugal force, the oil mist is condensed into oil drops, the oil drops are collected into an oil cup through an oil way, and the purified smoke is finally discharged along a fixed passage. The smoke after being treated by the oil fume treatment method still causes certain pollution to the environment.

Present smoke ventilator has set up the collection petticoat pipe that the size is wide big, can collect the oil smoke completely to installed with collection petticoat pipe and the collection oil extraction device of tub looks adaptation of discharging fume, however in the in-service use process, there is the contradiction in the smoke ventilator's of this type of structure and installation characteristic and smoke exhaust effect:

1. when smoke ventilator's mounted position was higher, the user had fine field of vision and culinary art space, but smoke exhaust effect of smoke ventilator lacks difficult assurance.

2. When the installation position of smoke ventilator is lower, smoke exhausting effect of smoke ventilator is better, but the user can not get enough cooking space, perhaps can receive the elbow when cooking.

3. In addition, the appearance sizes of different cooking utensils are different, and the spreading effect of the oil smoke is affected differently. The range hood is provided with uniform and unchangeable installation height and position, and cannot be suitable for various different cooking utensils.
