Abstract
The invention relates to a jet flow speed reduction dual-effect blind blade air port, and belongs to the technical field of ventilation air conditioners. The jet flow speed reduction dual-effect blind blade air port comprises an air port shell and movable blind blades at the position of the air port. The width of the movable blind blades is larger than or equal to six times of the width of an ordinary blind blade, so that airflow is decelerated in the air port, meanwhile, the airflow direction at an outlet is changed, parallel flow is changed into scattering flow, and the speed of the airflow is rapidly reduced after the airflow leaves the air port. The air speed of outflow air can be accurately controlled by adjusting the diffusion angle of the blind blades in the air port. When high flow speed is needed for the airflow to make the jet flow length large, the blind blades can be adjusted to be parallel to one another. When the flow speed of the airflow needs to be reduced quickly and the speed attenuation is very fast, the angle of the blind blades can be adjusted according to the attached graph, and due to the fact that the blind blades are long, the air speed at the outlet of the air port, namely the tail ends of the blind blades can be greatly reduced. The same air port can be used for jet flow and speed reduction at the same time. Speed reduction is achieved with the section change as the principle instead of mixing with the outside airflow.
Description
Technical field
The invention belongs to air conditioner technical field, particularly relate to a kind of jet reduction of speed economic benefits and social benefits air grille, can obtain
The air port of low speed flow can be obtained again to high velocity air.The extreme magnitude that speed reduces, effect is obvious.
Background technology
Air conditioner field uses the occasion of air grille to be typically when wall attachment jet, by regulating horizontal BAIYE
Angle is intended merely to adjust the angle of jet, owing to the feature that BAIYE width is the shortest makes air port can not change exit velocity.Ventilate
Field of air conditioning makes the air port kind of air-flow reduction of speed a lot, such as air diffuser, swirl diffuser etc., but is all belonging to and external air flow momentum
Conservation mixed type air port.
Summary of the invention
For the technical problem of above-mentioned existence, the present invention provides a kind of jet reduction of speed economic benefits and social benefits air grille, and it can make gas
Flow and flow out with jet or diffusion mode, thus reach the contrary purpose of jet and reduction of speed.
It is an object of the invention to be achieved through the following technical solutions:
One jet reduction of speed economic benefits and social benefits air grille of the present invention, including the movable shutters at tuyere shell and air port, described work
The width of dynamic BAIYE is 12-18cm, makes air-flow reduction of speed in air port, changes the direction of exit flow simultaneously, concurrent flow make into
Scattering stream, after air-flow leaves air port, speed decays rapidly.
Further, the movable shutters in described air port manually or automatically adjusts multiple angles, is worked off one's feeling vent one's spleen by change
The outlet section area of stream, makes gas speed and angle when leaving air port produce huge change；When BAIYE is parallel, jet
Streamline is parallel to each other, and air port muzzle velocity is big, and the length of jet is remote；When the angle of BAIYE is transferred to maximum, air goes out in air port
It is very big that mouth speed reduces amplitude, and especially by angle and the dual function of speed, air-flow is decayed faster after flowing out.
Further, described automatic adjustment is to connect movable shutters by driven by motor to turn shaft drive realization.
The invention have the benefit that
The width of BAIYE the most of the present invention is different from common BAIYE, is more than 6 times of general BAIYE width, reaches even to surpass
Cross the height in air port.
2. the present invention by adjust BAIYE angle, can adjust injection air-flow final outlet sectional area, make air-flow with
Jet or diffusion mode flow out, thus reach the contrary purpose of jet and reduction of speed.
3. the present invention integrates jet and reduction of speed function, and the principle of reduction of speed is different from the principle of other reductions of speed, reduction of speed
Effect increase at double.

Detailed description of the invention
Describe the present invention with embodiment below in conjunction with the accompanying drawings.
Embodiment 1: as Figure 1-Figure 5, the present invention includes a kind of jet reduction of speed economic benefits and social benefits air grille, including tuyere shell
1 and air port at movable shutters, the width of described movable shutters is 12-18cm, makes air-flow reduction of speed in air port, changes simultaneously
The direction of implication stream, is made into scattering stream by concurrent flow, and after air-flow leaves air port, speed decays rapidly.
The movable shutters in described air port manually or automatically adjusts multiple angles, breaks by changing the stream that of exit flow
Face area, makes gas speed and angle when leaving air port produce huge change；When BAIYE is parallel, jet stack is the most flat
OK, air port muzzle velocity is big, and the length of jet is remote；When the angle of BAIYE is transferred to maximum, air reduces in air port muzzle velocity
Amplitude is very big, and especially by angle and the dual function of speed, air-flow is decayed faster after flowing out.
Described automatic adjustment is to connect movable shutters by driven by motor to turn shaft drive realization, concrete actuating device
It is nested with on the sprocket wheel of movable shutters rotating shaft and the sprocket wheel of motor output shaft by driving-chain, it is achieved transmission, thus unlatching activity hundred
Leaf.
