Abstract
The utility model relates to an oil fume absorbing machine, in particular to an air curtain generation device of the oil fume absorbing machine. The air curtain generation device of the oil fume absorbing machine comprises a centrifugal air blower, an air guiding cavity body, and a linear air curtain air outlet opening, wherein the centrifugal air blower is arranged on the air guiding cavity body, the linear air curtain air outlet opening is arranged on the air guiding cavity body, and an air interfering plate ensuring the air outlet of the linear air curtain air outlet opening to be uniform is arranged in the air guiding cavity body. The utility model does not influence air curtain air output while the narrowest height designed through a fume machine body is ensured, and breaks the contradictory relation of the air curtain generation device and the oil fume absorbing machine, the structure is simpler and stable; the maintenance is more convenient; the working noise is smaller, and the process is easier to be manufactured.
Description
Technical field
The utility model relates to a kind of range hood, relates in particular to a kind of Range Hood Wind Screen Generator.
Background technology
Form by through-flow fan blade, rotating shaft electric motor, anion generator, wind-guiding cavity with the anionic wind curtain structure in the family expenses range hood of anion air curtain is many on the market at present.Need do narrowly but all exist because of the range hood body, limit the diameter of through-flow fan blade, cause the air output of whole air curtain less than normal.Simultaneously, use motor to cooperate with through-flow fan blade, the course of work exists through-flow fan blade and motor to be difficult to remain on same axle center, is easy to generate unnecessary noise.
Summary of the invention
For the technical problem that the air curtain generating means that solves in the above-mentioned family expenses range hood exists, the purpose of this utility model provides a kind of Range Hood Wind Screen Generator.It can guarantee cigarette machine body height when guaranteeing the air curtain air output, make taking into account of performance and outward appearance, reduces operating noise.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
Range Hood Wind Screen Generator, comprise centrifugal blower, wind-guiding cavity and linear air curtain air outlet, described centrifugal blower is arranged on the wind-guiding cavity, and linear air curtain air outlet is arranged on the wind-guiding cavity, is provided with in the described wind-guiding cavity to make the air-out of linear air curtain air outlet disturb aerofoil uniformly.
As preferably, be provided with anion generator in the above-mentioned wind-guiding cavity.
As preferably, above-mentioned disturb the centrifugal blower air intake vent place that aerofoil is arranged on the wind-guiding cavity, disturb aerofoil and be at least 1.
As preferably, the both sides of above-mentioned wind-guiding cavity are respectively equipped with centrifugal blower, and the centrifugal blower air intake vent place of wind-guiding cavity is provided with at least 1 described aerofoil of disturbing respectively.Being respectively equipped with centrifugal blower in the both sides of wind-guiding cavity is that air-out is more even.Middle part as wind-guiding cavity in preferred again, the above-mentioned scheme is provided with anion generator.
As preferably, the above-mentioned aerofoil of disturbing is an arc.
As preferably, above-mentioned wind-guiding cavity is provided with 2 linear air curtain air outlets that are parallel to each other.Article 2, linear air curtain air outlet air-out can form double-deck air curtain.
The utility model uses centrifugal blower that wind is blown out by the air curtain outlet, and it is more stable with cooperating of rotating shaft electric motor that the structural behaviour of centrifugal blower is compared through-flow fan blade, can reduce operating noise.But, can not satisfy the length of whole piece air curtain because there is certain air-out scope in centrifugal blower.Therefore, the utility model installs additional disturbs the wind sheet air curtain can evenly be blown out in linear air curtain air outlet, and wherein the difference between maximum wind velocity and minimum windspeed is less than 0.4m/s.
The beneficial effects of the utility model are: can when guaranteeing the narrowest height of cigarette machine body design, not influence the air curtain air output, break contradictory relation between the two, and structure is simpler, stable; Keep in repair more convenient; Operating noise is littler, the easier making of technology.
