Referring to fig. 1 to 3, the air outlet panel 100 has an outer side and an inner side opposite to each other, a concave area 1a is formed on the outer side of the air outlet panel 100, an air outlet 1b is formed in a local area of the concave area 1a, and the air outlet 1b is communicated with the concave area 1a to form an air outlet channel.
In this embodiment, the inner side and the outer side of the air outlet panel 100 are defined with respect to the flow direction of the air flow, and when the air flow flows, the air inlet side of the air outlet panel 100 is the inner side, and the air outlet side is the outer side. The concave area 1a is disposed at the air outlet end of the air supply channel through which the air flows.
It should be noted that, the concave area 1a may be a regular groove or an irregular groove, and the bottom wall of the groove may be a plane or a curved surface, and the concave area 1a may of course be configured in other possible shapes, specifically, may be determined according to practical situations, so long as the air outlet 1b and the bottom wall of the groove can be communicated, which is not limited in the scope of the present utility model.
In this embodiment, the air outlet 1b is formed through a partial area of the recessed area 1a, that is, a surface of the remaining area of the recessed area 1a, that is, a surface of the peripheral side of the air outlet 1b corresponding to the recessed area 1a, and the inner wall surface of the air outlet 1b together define the air supply channel, so that the cross-sectional area of the recessed area 1a is larger than the cross-sectional area of the air outlet 1 b.
In the technical scheme provided by the utility model, when the fan is in operation to supply air to the air outlet hole 1b of the air outlet panel 100, the air flow firstly passes through the air outlet hole 1b, then the air flow positioned at the periphery of the air outlet hole 1b passes through the concave area 1a, and then the air is discharged from the net cover 20, and the air flow passes through the air outlet hole 1b to flow to the concave area 1a, so that the sectional area of the concave area 1a is larger than that of the air outlet hole 1b, the reflux of the air flow is reduced, and the air quantity is increased. The air flow with the same flow rate is larger at the air outlet hole 1b, when the air flow flows to the concave area 1a, the air flow rate can be reduced, the concave area 1a communicated with the air outlet hole 1b is arranged at the air outlet end of the air outlet hole 1b, the air flow corresponding to the concave area 1a can convert the original local static pressure into dynamic pressure in the surrounding area of the air outlet hole 1b, so that the air outlet resistance of the air flow is reduced, the pneumatic noise of the air outlet can be reduced, and the power consumption is reduced, thereby solving the problems of larger noise and larger power consumption of the existing air outlet panel 100.
In the prior art, the cross-sectional area of the air outlet hole 1b on the conventional air outlet panel 100 is unchanged at the air outlet end, and the air flow has more backflow phenomenon, so that the air volume of the air supply is smaller.
In this embodiment, referring to fig. 3, the air outlet hole 1b is configured as a flanging hole, so that the air outlet hole 1b is formed with an annular flanging 101 protruding from the inner side of the air outlet panel 100, and the aperture of the annular flanging 101 is at least partially gradually increased in the inward direction. So set up, in the region that air outlet 1b corresponds, the opening at the air inlet end then is bigger than the opening of air outlet end, then when the fan is arranged, then can collect more air current at the air inlet end of air outlet 1b, concentrate the air current. At this time, the airflow velocity of the air outlet 1b is high.
It should be noted that, in the preferred embodiment, the annular flange 101 increases gradually and sequentially in an inward direction, so that the air resistance is stable and the stability of the air flow is not affected by negligence in the process of flowing toward the air outlet end of the air supply channel.
Specifically, referring to fig. 3, in this embodiment, the air supply channel includes a collecting section 11, a guiding section 12, and a flow expanding section 13 sequentially disposed from inside to outside, where the collecting section 11 and the guiding section 12 are formed in the air outlet 1b, and the flow expanding section 13 is formed in the recessed area 1a; the aperture of the collecting section 11 is set to be larger than the aperture of the guide section 12. In this way, more air flow is collected in the collecting section 11, and the air flow can be concentrated and then flows to the expanding section 13 with larger sectional area through the guiding section 12.
In this embodiment, the flow guiding section 12 and the flow collecting section 11 are arranged in a circular arc transition. The circular arc transition can change the direction of the air flow more smoothly, and reduce wind resistance; the arc transition can avoid the formation of vortex, reduce noise to can make the air current pass through the passageway more evenly, thereby improve pneumatic performance's stability and reliability.
It should be noted that the flow expansion section 13 is formed in the concave region 1a, the length of the flow expansion section 13 in the inner-outer direction depends on the concave degree of the concave region 1a, and the size of the cross section of the flow expansion section 13 depends on the projection area of the concave region 1a in the inner-outer direction.
In this embodiment, in the direction from inside to outside, the length of the collecting section 11 is a, the length of the guiding section 12 is B, and the length of the expanding section 13 is C, wherein 65mm is equal to or less than a+b+c is equal to or less than 80mm. By the arrangement, the compression resistance of the air outlet panel 100 is guaranteed, and the possibility of the air outlet panel 100 from being pulled apart in the manufacturing process is guaranteed. Because the air outlet panel 100 is generally a plastic part, in the manufacturing process, a drawing die is required, and when the distance between the air supply channel in the inner and outer directions is too large, that is, a+b+c is greater than 80mm, stress concentration occurs on the surface of the plastic part due to friction between the plastic part and the mold cavity. If there are weak points (e.g., gates, ejector pin marks, etc.) on or in the plastic part, the stresses in these areas will exceed the strength of the material, resulting in spalling.
When the distance between the air supply channels in the inner and outer directions is too small, namely a+b+c is smaller than 65mm, the thickness of the air outlet panel 100 is thinner, when the air outlet panel 100 is arranged on an outdoor unit of an air conditioner, the condenser is easy to frost or even ice under the working condition of low temperature in winter, and then the air supply quantity of the fan is reduced in the working process of the fan, and the air quantity attenuation of the corresponding air supply channel of the expansion section 13 is smaller, so that the compression resistance of the air outlet panel 100 is increased.
In this embodiment, the collecting section 11, the guiding section 12 and the expanding section 13 also satisfy the following relational expression, 10% to 20% of C/(A+B+C). When the length of the expansion section 13 is too large, i.e. C/(a+b+c), is greater than 20%, the risk of demolding and pulling crack is caused, and when the length of the expansion section 13 is too small, i.e. C/(a+b+c), is less than 10%, the air volume is increased slightly.
In this embodiment, the cross-sectional area of the air outlet hole 1b is S1, the cross-sectional area of the recessed area 1a is S2, in fig. 4 of the specification, the recessed area 1a is the area of the whole square area, and S2-S1 is the area of the recessed area 1a projected on the air outlet panel 100 in the inner and outer directions, where (S2-S1)/S1 is 20% or more and 40% or less. The arrangement ensures the beautiful appearance of the air outlet panel 100, and can effectively promote the air quantity, when (S2-S1)/S1 is more than 40%, the area of the flow expansion section is overlarge, the aesthetic property is poor, the manufacturing cost is also larger, and when (S2-S1)/S1 is less than 20%, the concave area 1a prevents the performance of the backflow effect from being reduced, and the air quantity is improved and worsened.
Specifically, referring to fig. 1, 2 and 4, in this embodiment, the recessed area 1a is square, and the air outlet hole 1b is circular, where the center of the cross section of the recessed area 1a coincides with the center of the circular hole. In this way, the plurality of triangular-like recessed areas 1a on the circumferential side of the circular air outlet hole 1b can be left-right or up-down symmetrical with respect to the vertical center line or the horizontal center line with respect to the air outlet hole 1b. Of course, the shape of the concave area 1a is not limited to the above shape, and the concave area 1a may be a concentric circle with a diameter larger than that of the air outlet 1b, and of course, the shapes of the concave area 1a and the air outlet 1b are not limited to the above examples, and other modifications are possible by those skilled in the art in light of the technical spirit of the embodiments of the present disclosure, and all the functions and effects implemented by the above embodiments are included in the protection scope of the embodiments of the present disclosure as long as they are the same or similar to the embodiments of the present disclosure.
