Description
Technical field
The utility model relates to air conditioner ventilation apparatus fields, and in particular to a kind of diffusing device.
Background technique
Air diffuser is the air outlet of air-conditioning or ventilation, exactly allows air outlet air-out direction to be divided into multidirectional flowing, is commonly used in
The air outlet setting in the large area such as hall place is evenly distributed so as to fresh air, convenient for the rapidly and uniformly mixing of air, will not produce
The wind speed of raw part is excessive, and the major function of air diffuser is to change air movement direction, keeps air velocity, enables air to fast
Speed mixes with room air or reaches somewhere, and in air-conditioned room, the air and room air of air diffuser discharge carry out caloic friendship
Necessarily cause the flowing of room air after changing, and different air flow conditions has different adjusting temperature effects, thus
The shape and structure of air diffuser can make to be formed in conditioned area than faster, uniform stable air velocity, if air-flow from
The surface of the gap of plane toward protrusion is blown into air-flow along tangent line, then air-flow by after leaving gap relatively long one section away from
Can all it adhere on the surface from interior, this air flowing that just will drive periphery promotes mixing efficiency.
Therefore how problem above solves to be those skilled in the art's technical issues that need to address.
Summary of the invention
Therefore, the utility model is exactly the improvement made in view of problem above, and the utility model for above-mentioned in order to ask
Topic provides a kind of diffusing device, and the utility model is achieved through the following technical solutions above-mentioned purpose.
The utility model provides a kind of diffusing device, comprising: outer cover, blast pipe, flow distribution plate, annular protrusion；
The outer cover is hollow hemisphere structure；
The blast pipe is that tubular structure perforation is arranged on outer cover, and blast pipe axis crosses the outer cover centre of sphere；
The flow distribution plate is circular slab, extends along circular slab outer circumferential edge to central point and is equipped with annular groove, flow distribution plate setting
Below blast pipe；
The annular protrusion is annular semicircular body, and the bottom edge inner ring of annular protrusion is set in the upper round edge of flow distribution plate, annular
Protrusion forms " S " type transition with the annular groove on flow distribution plate, and there are certain distances with outer cover inner wall for annular protrusion.
In one embodiment, the air inlet inside pipe wall is equipped with helical raised.
In one embodiment, the flow distribution plate center is equipped with micro- through hole.
In one embodiment, the flow distribution plate and annular protrusion can whole installations.
In one embodiment, the outer cover inner wall is equipped with guide groove.
The utility model the utility model has the advantages that
1, the utility model air-flow from the gap of plane toward protrusion surface be blown into air-flow along tangent line, then air-flow will from
As soon as can all adhere in relatively long section of distance after gap of cracking on the surface, this air flowing that will drive periphery is promoted mixed
Close efficiency.
2, the utility model has the function of biggish induction room air.
Detailed description of the invention
Fig. 1 is the utility model overall structure cross-sectional view.
Specific embodiment
The preferred embodiment of the utility model will be described in detail by reference to attached drawing, in this way for field that the present invention belongs to
Existing technical staff in ordinary skill people for these embodiments easy to accomplish.However the utility model can also be each
The different form of kind is realized, therefore the utility model is not limited to embodiments described hereinafter.In addition, in order to more clearly describe
The present invention will be omitted with the component that the utility model is not connect from attached drawing.
As shown in Figure 1, the utility model provides a kind of diffusing device, comprising: outer cover 1, blast pipe 2, flow distribution plate 3, annular
Protrusion 4；
The outer cover 1 is hollow hemisphere structure；
The blast pipe 2 is that tubular structure perforation is arranged on outer cover 1, and 2 axis of blast pipe crosses 1 centre of sphere of outer cover；
The flow distribution plate 3 is circular slab, extends along circular slab outer circumferential edge to central point and is equipped with annular groove 31, flow distribution plate 3
It is arranged below blast pipe 2；
The annular protrusion 4 is annular semicircular body, and the bottom edge inner ring of annular protrusion 4 is set in the upper round edge of flow distribution plate 3, ring
Shape protrusion 4 forms " S " type transition with the annular groove 31 on flow distribution plate 3, and there are certain distances with 1 inner wall of outer cover for annular protrusion 4.
Preferably, as an embodiment, 2 inner wall of blast pipe is equipped with helical raised, increases intake velocity.
Preferably, as an embodiment, 3 center of flow distribution plate is equipped with micro- through hole, increases mixing efficiency.
Preferably, as an embodiment, the flow distribution plate 3 and annular protrusion 4 can whole installation, be easily installed.
Preferably, as an embodiment, 1 inner wall of outer cover is equipped with guide groove, and spray distance is remote, improves new
The mixing efficiency of wind and room air.
The inventive principle of the utility model is as follows:
When work, fresh air enters inside air diffuser through blast pipe 2, the past annular of the annular groove on gas shock flow distribution plate 3
The surface of protrusion is blown into air-flow along tangent line, air-flow leave outer cover 1 and annular protrusion 4 be formed by it is opposite after slype
As soon as can all be attached on 1 inner surface of outer cover in longer section of distance, this air flowing that will drive periphery promotes mixing efficiency,
Improve the mixing efficiency of fresh air and room air.
