Abstract
The utility model discloses an air -out cover for cooker hood, including cover body bottom and cover body head, cover body bottom is the air inlet end, cover body head hold its characterized in that for the air -out: it has a plurality of through -holes and makes cover body head at the local or whole reticular structure that is to open on the perisporium of cover body head. Compared with the prior art, the utility model has the advantages of: this air -out cover for cooker hood open on the perisporium of cover body head have a plurality of through -holes and make cover body head local or whole be reticular structure after, the range hood during operation, when airing exhaust through the fan to drawing of surrounding air penetrate, mixing and reach the noise reduction effect, especially the percent opening satisfies certain back that requires, the noise reduction effect is more obvious.
Description
Technical field
This utility model relates to a kind of outlet housing for range hood.
Background technology
At present, the air outlet at range hood is typically fitted with outlet housing, and existing outlet housing the most all includes cover body
Bottom and cover body head, be arranged on bottom cover body on the fan outlet of range hood, be i.e. air intake bottom cover body, cover
Body head is outlet air end, and the air-flow flowed out from fan outlet is flowed outwardly by outlet housing.But, due to existing air-out
The cover body head of cover is not provided with any through hole on its straight tube wall, thus, during range hood work, air-flow is from outlet housing
Outlet housing surrounding air cannot carry out injection and blending when flowing through, so, outlet housing has acted primarily as and has guided air-flow
The effect flowed out, and substantially there is no effect for reducing the noise of fan outlet.In sum, need to existing go out
Fan housing structure is further improved.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, it is provided that a kind of simple in construction, fall
Make an uproar the effective outlet housing for range hood.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: this is used for the outlet housing of range hood, bag
Including bottom cover body and cover body head, be air intake bottom described cover body, described cover body head is outlet air end, and its feature exists
In: on the perisporium of described cover body head, have multiple through hole and make cover body head partly or wholly in mesh-structured.
Preferably, described cover body head is straight-tube shape.
As a kind of preferred version, described through hole be distributed on the whole perisporium of cover body head make cover body head overall in
Mesh-structured.
As another kind of preferred version, the perisporium at the adjacent end edge that described through hole is distributed on cover body head makes cover
Body head local is in mesh-structured.
In order to obtain more preferable noise reduction, described through hole is circular hole.
In order to obtain more preferable noise reduction, the percent opening δ of described cover body head is 5%≤δ≤60%.
Preferred as any of the above-described scheme, the import that described outlet housing is formed in one bottom part, and described cover body in
Square, the outlet of described cover body head is rounded.So, from square orifice to circular port transition, cover body head bottom cover body
Portion is cylindrically.
Compared with prior art, the utility model has the advantage of: this is used for the outlet housing of range hood at cover body head
Have multiple through hole on perisporium and make cover body head partly or wholly in after mesh-structured, during range hood work, pass through
During blower fan air draft, injection, the blending of surrounding air are reached noise reduction, after particularly percent opening meets certain requirements,
Noise reduction becomes apparent from.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment one；
Fig. 2 is the structural representation of this utility model embodiment two.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Embodiment one:
As it is shown in figure 1, the outlet housing in the present embodiment includes bottom cover body 1 and cover body head 2, whole outlet housing is one
Body formed part, bottom cover body, 1 is air intake, and import is square, and cover body head 2 is outlet air end, i.e. outlet is circle.
In the present embodiment, cover body head 2 cylindrically, has equally distributed in the circumferential wall of whole cover body head 2
Through hole 21, so, cover body head 2 entirety is mesh-structured.Further, in order to obtain more preferable noise reduction, through hole
21 is the circular hole that aperture is identical.
Additionally, in order to noise reduction is more preferable, the percent opening δ of cover body head 2 is 5%≤δ≤60%.The size of percent opening
Can be adjusted according to the size of outlet housing.
During range hood work, during by blower fan air draft, injection, the blending of surrounding air are reached noise reduction, noise reduction
Effect is obvious.
Embodiment two:
As in figure 2 it is shown, in the present embodiment, the through hole 21 of cover body head 2 is the circular hole that aperture is identical, these through holes 21
Be distributed in the circumferential wall at adjacent end edge of cover body head 2, so, cover body head 2 local in mesh-structured, and
The percent opening δ of cover body head 2 is %≤δ≤60%.In remaining structure of outlet housing in the present embodiment and embodiment one
Outlet housing structure identical, the most reinflated description at this.
The foregoing is only preferred implementation of the present utility model, it is noted that for those of ordinary skill in the art
Speech, without departing under principle premise of the present utility model, can carry out multiple remodeling or improvement to this utility model, such as
Cover body head is in addition to using cylindric structure, it is also possible to using the structure of other straight-tube shapes, these are regarded as this reality
Within novel protection domain.
