Therefore, in order to increase the turbulence of the rectangular jet flow and improve the cooling or heating effect of the air conditioner, an air distributor needs to be additionally arranged at the air outlet of the air conditioner, so that the turbulence of the rectangular jet flow can be controlled within a certain numerical range, the rectangular jet flow is diffused more uniformly, and the best cooling or heating effect is finally achieved. The existing air distributor is designed by additionally arranging a plurality of rows of baffles with certain deflection angles at an air outlet, so that the spraying direction of rectangular jet flow is changed.
However, the existing air distributor has the following problems: 1. the existing design can not well increase the turbulence degree of jet flow, only simply realizes the control of jet flow injection direction, and the problem of jet flow concentration is not solved, so that the refrigerating and heating effects can not be well improved, and 2, the existing air distributor can not solve the problem of water condensation at the air outlet of the air conditioner, thereby bringing potential safety hazards and unnecessary damage to the use of the air conditioner. In conclusion, the invention provides an air distribution device which can increase jet turbulence and solve the problem of water condensation at an air outlet of an air conditioner.

The invention provides a technical scheme that: an air distribution device based on rectangular jet flow film oscillation is shown in figures 1-5 and comprises an air distribution plate 1 and an FEP film 2 arranged on the air distribution plate 1, wherein a plurality of identical air exhaust holes 3 are arranged on the air distribution plate 1 in a penetrating manner. The air exhaust holes 3 are rectangular and are designed in a single-layer grid shape, so that the space can be saved to the maximum extent. Compared with the air outlet of a common central air conditioner, the thickness of the air outlet is larger, so that the air heated or cooled by the air conditioner moves for a longer distance at the air outlet, the FEP film 2 vibrated by air beating fully disturbs jet flow, finally ejected air becomes turbulent flow with larger turbulence degree, and the turbulent flow can be uniformly diffused indoors, thereby improving the cooling or heating effect and avoiding the direct blowing of the air conditioner. The air exhaust holes 3 are arranged on the air distribution plate 1 at equal intervals. The length-width ratio of the FEP film 2 is equal to that of the air exhaust hole 3, and the self-excited flapping experiment of the rectangular jet flow film shows that the length-width ratios of the optimal FEP film 2 corresponding to the building areas of air conditioners with different parameters and different use environments are different, under the condition of the length-width ratios, the film beats most violently under the same wind speed and flow, the turbulence degree at the central line and the cross section of the air outlet is maximum, and the formed vortex is maximum, so that the better jet flow mixing effect is achieved. The thickness of the FEP film is 30-60 μm. Experiments show that the film with the thickness interval can flap normally at a higher frequency at a lower wind speed, and can ensure that less noise is generated in the flapping process, so that the influence on the life of a user is reduced. The width of the FEP film is slightly less than the width of each rectangular opening of the air distributor so that the film can flap normally, and the length of the FEP film is determined by the length-width ratio of the film corresponding to different used spaces. The 3 inboards in hole of airing exhaust is provided with the draw-in groove, and the draw-in groove passes through fixing device 5 and links to each other with a broadside of FEP film 2, and fixing device 4 is two long banding anchor clamps, and its main function is fixed FEP film 2 for the centre gripping, gathers and influence air conditioner air-out scheduling problem for avoiding the dust, long banding fixing device 4 should design the semicircle column of the PVC (polyvinyl chloride) material of diameter 2mm, and 2 centre grippings of FEP film are between two anchor clamps, and angular adjustment is the most suitable angle of beating by the bat to it is clean easily to dismantle. The width of FEP film 2 is less than the width of air exhaust hole 3, and the internal surface of grid plate 1 is provided with connecting portion 5, and connecting portion 5 connects grid plate 1 and air conditioner. The outer surface of the air distribution plate 1 is provided with the heat insulation plate 6, so that the generation of air outlet condensate water caused by overlarge temperature change of an air outlet of the air conditioner is reduced, potential safety hazards are reduced, and the service life of the air conditioner is prolonged. In addition, the PE (polyethylene) material has good sound insulation effect, and can reduce the influence of the noise generated by the operation of the air conditioner on a user. The shape of the heat preservation plate 6 is matched with the outer surface of the air distribution plate 1, and the thickness of the heat preservation plate is 1 mm.
The working principle of the invention is as follows:
the invention discharges cold air generated by the air conditioner into a room in a turbulent state by self-excited flapping of the FEP film in the air exhaust hole 3, and finally achieves the effect of cooling without wind feeling. When the jet flow enters the channel 1 from the inner side of the channel and blows through the film, aerodynamic instability can be generated, so that film flutter is formed, the film 2 additionally arranged in the air outlet channel starts to flap, the flap film can naturally excite the jet flow to generate self-oscillation depending on time, and finally global oscillation is generated.
It has been recognized that such dynamic self-oscillation significantly increases the turbulence of the jet, eventually making it turbulent, while the film is continuously flapped by the influence of the subsequent jet, achieving the self-oscillation flapping effect; paste at the thin PE heated board 6 hydroscopicity on air distribution plate 1 surface low, the coefficient of heat conductivity is low, and the heat insulating ability is good, can be fine prevent the air conditioner surface because of the condensation phenomenon that local supercooling leads to because PE heated board 6 adopts the foaming of polyethylene plastic micelle to form, have very excellent sound absorption function, can reduce the noise that the air conditioner operation in-process produced by a wide margin.
The FEP film 2 is fixed on the inner side of a single-layer grid-shaped air conditioner exhaust hole 3 through the clamping of a fixing device 4, and a clamping groove matched with the fixing device 4 is formed in the inner side of the exhaust hole 3, so that the FEP film 2 is easy to detach. Experiments show that the self-oscillation of the jet flow is affected differently by the flutter of the film with different length-width ratios, so that the film with different length-width ratios is suitable for different building areas, and the length-width ratios of the films corresponding to the different building areas can be obtained through subsequent experiments. This design allows the user to change the film for different use environments, increasing the flexibility and sustainability of use of the invention.
Through the design of the invention, the refrigeration or heating effect of the air conditioner can be greatly improved, the body feeling of people is enhanced, the occurrence of air conditioner diseases is reduced to a certain extent, the efficiency of the air conditioner can be improved, precious power resources are saved, the occurrence of water condensation at the air outlet of the air conditioner can be effectively avoided through the thin PE heat-insulating plate 6, the corrosion of the shell and the interior is reduced, and the service life of the air conditioner is prolonged.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
