The utility model proposes a kind of wind shield, the air conditioner room unit of the wind shield is installed, and includes the room The air conditioner of interior machine.Here, air conditioner room unit can be on-hook or cabinet-type air conditioner, for the ease of statement, the description below In, will specifically it be illustrated by taking on-hook as an example.Wind shield 10 is mounted at the air passage of air conditioner room unit, can specifically be pacified Mounted in air outlet, can also be installed in air passage (on the inside of air outlet).

In the utility model embodiment, as shown in Figures 1 to 5, wind shield 10 includes plate body 11 and multiple blinds 12. The plate body 11 offers multiple openings 110 along left and right to extension on the plate body 11, the blinds 12 is installed on described Plate body 11, for being oriented to by the air-flow of the blowout of opening 110, multiple irregularly-shaped holes have been provided on each blinds 12 120, each irregularly-shaped hole 120 includes the multiple bar hole 120a to arrange along circular trace, and each bar hole 120a is equal Extend backwards to the center of the circular trace, and the direction that provides of the bar hole 120a is inclined in the same direction in the circumferential direction of the circular trace Tiltedly set.Wherein, the multiple blinds 12 includes at least one first blinds 12a and at least one second blinds 12b；Described 100th Leaf 12a as its derived air-flow and the air-flow as derived from the second blinds 12b will be intersected.

Specifically, before blinds 12 is not provided with, when air-flow is blown out by opening 110, air-flow, which is not subject to be oriented to, to be made With, and directly blown out by opening 110, its airflow direction will not change.After setting blinds 12, air-flow can be along blinds 12 Extending direction and blow out.

Extending direction of the blinds 12 on plate body 11 has two, and first direction is blinds 12 intersects with plate body 11 Line extending direction, second direction are extending direction of the blinds 12 backwards to plate body 11.The extension side being mentioned in the description below To in the case of not being specifically noted, all referring to the extending direction of blinds 12 and 11 intersecting lens of plate body.

Blinds 12 is provided in 110 peripheries of opening, if blinds 12 is vertical with plate body 11, then blown by opening 110 The air-flow gone out can directly be blown out along blinds 12；If blinds 12 is tilted a certain angle towards opening 110, then by opening 110 The air flow direction of blowout changes.

Here, with reference to Fig. 2-a, the extending direction of junction of the blinds 12 on plate body 11 along left and right to extension, Blinds 12 can be inclined upwardly at this time, can also tilt down.With reference to Fig. 2-b, extending direction of the blinds 12 on plate body 11 Can be vertically to extension, blinds 12 can be tilted to the left at this time, can also be tilted to the right.Blinds 12 is on plate body 11 Extending direction can also be lower section extension to the left, at this time, blinds 12 can inclined upward to the left, can also incline lower section to the left Tiltedly.

The air-flow as derived from the first blinds 12a, the embodiment to intersect with the air-flow as derived from the second blinds 12b have more Kind, the description below will be discussed in detail with multiple embodiments.

In one embodiment, it is tilted to the right with reference to Fig. 2-b, the first blinds 12a vertically to extension, the second blinds 12b Positioned at the right of the first blinds 12a, the second blinds 12b is approximately along upper and lower extension, and towards left bank.At this time, by two kinds of blinds 12 Derived air-flow be intersected in plate body 11 nearby (confluence w) as depicted, wind energy be lost larger, calm sense best results, But at the same time, refrigeration effect is general.Further, since space is limited at the air outlet of air conditioner, air-flow easily forms vortex, so that meeting Cause noise larger, air-flow blowout amount is also less.Certainly, can be with plate body 11 with reference to Fig. 2-d and Fig. 2-e, the second blinds 12b Vertically, or towards the right side (as long as its angle of inclination is not more than the first blinds 12a angles of inclination) is slightly tilted, at this time, by two Air-flow derived from kind blinds 12 is intersected in the front side of plate body 11, and air-flow is broken up in the front side of plate body 11, after being blown out due to air-flow Mixed with normal temperature laboratory air-flow, wind sense is milder, and calm sense effect is preferable, and refrigeration effect is also preferable.

On the basis of a upper embodiment, with reference to Fig. 2-f, in order to make calm sense better, and refrigeration effect is also preferable, makes an uproar Sound is relatively low at the same time, and multiple blinds 12 can form multiple blinds groups to arrangement in left and right.Wherein, each blinds group is included from left To the right, vertically to the No.1 blinds 121 for extending and being tilted to the left, vertically to extension and vertical with plate body 11 No. two hundred Leaf 122, vertically to extension and vertical with plate body 11 No. three blinds 123, and vertically to extending and be tilted to the right No. four blinds 124.Wherein, after air-flow derived from No.1 blinds 121 and No. two blinds 122 crosses, in its mixed airflow, a part Broken up, remainder air-flow is the first air-flow I.After air-flow derived from No. three blinds 123 and No. four blinds 124 crosses, it is mixed Close in air-flow, a part is broken up, and remainder air-flow is the second air-flow II.At this time, the first air-flow I and the second air-flow II can be Cross again from 10 distant place of wind shield.Secondary due to air-flow crosses, the air-flow as derived from each this blinds group, no Only wind energy loss is smaller, and refrigeration effect is preferable, and noise is also smaller, and calm sense experience is splendid.

It is unlike the embodiments above, in another embodiment with reference to Fig. 2-a, the first blinds 12a along left and right to extension, And tilt down, at this time, the second blinds 12b can be located at the lower section of the first blinds 12a, and the second blinds 12b can be approximately along a left side Dextrad extends, and the second blinds 12b can not be tilted in upward and downward, can also be inclined upwardly, can also slope slightly downward at this time (as long as its angle of inclination is not more than the first blinds 12a angles of inclination), at this time, it can also be crossed by the two derived air-flow.

In another embodiment, prolong left and right to extension with reference to Fig. 2-c, the first blinds 12a edge, and tilt down, the Two blinds 12b are located at the lower left side of the first blinds 12a, and the second blinds 12b is tilted to the right vertically to extension；Or second Blinds 12b is located at the lower right side of the first blinds 12a, and the second blinds 12b is tilted to the left vertically to extension.At this time, by the two Derived air-flow can cross.In the present embodiment, the air-flow as derived from the first blinds 12a has two components, one of component It is forward, another component is downward；The air-flow as derived from the second blinds 12b has two components, one of component be to Right (left side), another component is forward.So two forward components can be superimposed blowout, downward component and to the right After the component on (left side) crosses, air-flow (left side) inclined downward to the right.Here, due to air-flow and the 200th derived from the first blinds 12a The mode that crosses of air-flow derived from leaf 12b is not that face (face is that finger direction is substantially opposite) crosses, after the two crosses, a part of gas Stream is broken up, and a part of air-flow can blow to user, and wind energy loss is smaller, and calm sense effect is also preferable.

Further, since being provided with multiple irregularly-shaped holes 120 on plate body 11, this wind shield 10 can also strengthen calm sense effect Fruit.Here, wind shield 10 realizes that the principle of calm sense is mainly as follows：Firstly, since bar hole 120a's provides direction in the circle It is obliquely installed in the same direction in the circumferential direction of shape track, therefore, compared to for the bar hole 120a for extending vertically through plate body 11, gas passes through Cross it is this be obliquely installed bar hole 120a when, gas flow distance is longer, and the kinetic energy loss of air-flow is more, it is calm sense effect more It is good.Secondly, the gas flowed out by this bar hole 120a being obliquely installed, its gas flow can change, so so that The intensity that wind shield 10 blows out air-flow has weakened, so as to improve the calm sense effect of outlet air air-flow.Finally, through irregularly-shaped hole 120 The gas of outflow can form swirling eddy, interact between multiple swirling eddies, break up mutually, therefore, when air-flow passes through When the wind shield 10 that this patent proposes is blown to human body, current rate weakens, air-flow comfort level higher.

Technical solutions of the utility model and install multiple blinds by using multiple openings 110 are set on plate body 11 12, on the one hand by the way that part blinds 12 is obliquely installed, will can be intersected by the air-flow of multiple blowouts of opening 110；So as to portion Air-flow is divided to be broken up；On the other hand, fraction can also be flowed out from irregularly-shaped hole, the air-flow velocity finally blown out by wind shield 10 It is relatively low, the direction variation of air-flow, so that, the calm sense effect of air-flow of blowout is preferable.

With reference to Fig. 4, in a preferred embodiment, the bar hole 120a's provides direction and the 11 thickness side of plate body To angle be α, α is more than 0 ° and less than or equal to 60 °.

Specifically, when α (0 °, 60 °] when, after gas flows through bar hole 120a, the degree of deflection of air-flow is moderate, so as to Enough so that the air-flow of different bar hole 120a outflows realizes preferable interaction, improve mixed wind effect, finally realize air conditioning chamber The calm sense of interior machine outlet air air-flow.

It should be noted that the calm sense refers to the moderate strength of outlet air air-flow, user is enabled to feel to relax It is suitable.(0 °, 60 °] it is the maximum magnitude that the air-flow through multiple bar hole 120a outflows enough shows angle of inclination when well interacting, In another embodiment of this patent, and the ranging preferably from of bar hole 120a angles of inclination (0 °, 45 °], and if only if bar hole When angle between 11 thickness direction of 120a and plate body is 20 °, calm sense effect is best.

With continued reference to Fig. 4, in a further preferred embodiment, the extending direction of multiple bar hole 120a is in the circular rail Deflection is set in the same direction in the circumferential direction of mark.

For wind shield 10, its windproof effect cannot be too strong, can not be too small.Windproof effect is too strong to be caused to blow Effect is poor, so that indoor refrigeration effect can be influenced, (cold air of air conditioner is simply spread around air conditioner, it is difficult to diffuses to room Interior regional).

The extending direction of bar hole 120a can be radially extending along above-mentioned circular trace, for what is radially extended For bar hole 120a, multiple finally formed air-flow vortex effects of bar hole 120a are general, and vortex radius is also larger, so that by The air-flow repercussion effect that adjacent irregularly-shaped hole 120 is blown out is stronger, finally, the air-supply effect of air conditioner can be caused general, nothing Wind sense effect is also general (it should be noted that here, calm sense refers to that the wind sense that user experiences is smaller, rather than do not have).

In the present embodiment, the extending direction of bar hole 120a is made to deflection in the same direction in the circumferential direction of the circular trace to set Put, in this way, there is the trend towards the circular trace center flow by the air-flow of each bar hole 120a outflows, can also reduce The radius of turn of swirling eddy.So as to, swirling eddy itself vortex effect more preferably, its air supplying distance is relative to radially extending It is remote for bar hole 120a.Further, since air-flow is flowed out with vortex form, so when air-flow blows to user, there is court The dimension flowed to user, and rotation dimension, so that, the experience effect of user is splendid.Furthermore eddy airstream and air Evenly, the air-flow that user experiences is also milder for mixing.

With continued reference to Fig. 4, in a preferred embodiment, in order to ensure the calm sense effect of indoor apparatus of air conditioner outlet air air-flow, Each irregularly-shaped hole 120 includes the angular range of 3 to 12 bar holes 120a, the adjacent two bar hole 120a for 30 ° extremely 90 °, as a kind of preferred embodiment, the angle of adjacent two bar holes 120a is about 60 °, each irregularly-shaped hole includes bar hole 120a Quantity is 6, can either obtain preferable calm sense effect at this time, and outlet air air-flow can be avoided largely to be lost.

For on-hook, its air outlet is usually what rectangle was set, and the wind wheel inside on-hook is usually tubular wine wheel. In consideration of it, in order to corresponding with tubular wine wheel, in one embodiment, with reference to Fig. 1, the opening 110 is along left and right to being intervally arranged In on the plate body 11, each correspondence of blinds 12 is installed on 110 side in the lateral direction of the opening.Also It is that blinds 12 is vertically to extension, and its angled manner mainly has a variety of in left and right to inclination, its combination of arranging.

The first arrangement mode：With reference to Fig. 5 and Fig. 8, the first blinds 12a and the second blinds 12b towards institute The middle part for stating plate body 11 tilts extension.It is, the first blinds 12a is located at the left side of plate body 11 and is tilted to the right, second Blinds 12b is located at the right side of plate body 11 and is tilted to the left.After air-flow is from 110 blowout of opening of the left side of plate body 11, multiple Under under the first common guiding roles of blinds 12a, air-flow is blown to the right.After air-flow is blown out from 11 right openings 110 of plate body, more Under the common guiding roles of a second blinds 12b, air-flow is blown to the left, and two strands of air-flows are finally substantially intersected in the middle part of plate body 11 front Position, and air-flow for multiple directions is broken up, calm sense effect is preferable.

With continued reference to Fig. 5, in the running, wall has hysteresis power to tubular wine wheel to air-flow at left and right sides of on-hook air passage, So the throughput in the middle part of air outlet is maximum.In consideration of it, in the present embodiment, opening degree between two adjacent blinds 12 by Both ends are gradually reduced (here, opening degree refers to the minimum spacing between adjacent two blinds) to middle direction.In air passage, middle part Air-flow velocity is although larger, and the left and right sides is smaller, but the opening degree between two blinds 12 at the middle part of wind shield 10 is smaller, left and right The opening degree of both sides is larger, so, when tubular wine wheel is run, the air-flow at middle part a, part can be from the middle part of wind shield 10 The blowout of opening 110, another part branches to the left and right sides of wind shield 10, and is blown out by the opening 110 of both sides.Finally, by keeping off The air-flow velocity that aerofoil 10 is blown out is more uniform.For example, the opening degree between adjacent two wind shield 10, is passed one by one from centre to both sides Increase 5%~10%.

It is unlike the embodiments above, in order to make the air-flow that wind shield 10 is blown out in left and right to evenly, in this implementation In example, with reference to Fig. 8, the angle of inclination of the blinds 12 gradually increases from both ends to middle.For example, the angle of inclination of blinds 12 is certainly Increase by 5 °~10 ° one by one among the two of plate body 11 are lateral.

Second of arrangement mode：With reference to Fig. 6 and Fig. 7, the multiple blinds 12 is formed in multiple blinds of the left and right to arrangement Group, each blinds group include at least one first blinds 12a and at least one second blinds 12b, wherein, institute State the first blinds 12a extensions opposite with the second blinds 12b.For example, each blinds group can include a first blinds 12a With one second blinds 12b, the first blinds 12a and the second blinds 12b in left and right to being arranged alternately.Can also be each described hundred Leaf group includes two adjacent the first blinds 12a, and two adjacent the second blinds 12b, the two first blinds 12a Extension opposite with the two second blinds 12b.It is, of course, also possible to it is that each blinds group includes a first blinds 12a and two A or more the second blinds 12b, can also be including two or more the first blinds 12a and the second blinds of two or more 12b.

In above-described embodiment, linearly tilt and prolong with reference to Fig. 8, the first blinds 12a and/or the second blinds 12b Stretch setting；Or the first blinds 12a and/or the second blinds 12b is tilted to be extended in camber line and (extremely schemed with reference to Fig. 5 7).For along linearly extended blinds 12, more suddenly gathered by its derived air-flow velocity, noise is relatively large；In addition, its with The turning of 11 junction of plate body is larger, and the air-flow of blowout is larger to the impact force of blinds 12, and noise also can be bigger than normal.For camber line For the blinds 12 of extension, when air-flow flows to blinds 12 by opening 110, it can be flowed along the camber line of blinds 12, air-flow velocity phase To relatively slowly, windage loss is smaller, and noise is also smaller, and convection effects are also preferable.Certainly, in order to make the air-flow stream blown out by opening 110 Speed is unlikely to anxious and gathers, and undulate can also be set to set blinds 12, in this way, increasing flowing road of the air-flow on blinds 12 Footpath and contact area, air-flow velocity more relaxes as derived from blinds 12, and noise can also decrease.

In above-described embodiment, with reference to Fig. 8,12 inclined angle of blinds cannot it is excessive (angle of inclination refer to blinds from its with Position when plate body is vertical, the angle for being tilted towards side or bending and being formed；For curved blinds, its inclination angle The angle when tangent line and blinds of degree reference blinds end are perpendicular to plate body), can not be too small.If 12 angle of inclination of blinds It is excessive, for example, angle of inclination is more than 60 °, then, air-flow will be mainly gathered near plate body 11 as derived from blinds 12, such as This, the resistance of wind shield 10 is excessive, seriously affects refrigerating efficiency, and it is larger to also result in noise.Certainly, angle of inclination cannot mistake Small, for example, angle of inclination is less than 10 °, in this way, air-flow is difficult to cross, or the throughput to cross is less, and calm sense effect is beaten greatly Discount.In consideration of it, in the present embodiment, the first blinds 12a and the second blinds 12b left and right to angle of inclination be 10 °~60 ° (being more than or equal to 10 °, less than or equal to 60 °), such as 30 °, 45 ° etc..

Air conditioner room unit has multiple air supply patterns, when tubular wine wheel rotation is very fast, after air-flow blows to wind shield 10, by To the backstop action of wind shield 10, the air pressure in air passage is larger, and air-flow is difficult to send out.So, on the one hand, the interior of indoor unit changes The frosting quickly of hot device, seriously affects refrigerating efficiency.On the other hand, it is vortexed seriously in air passage, noise is larger, influences user experience. In consideration of it, in the present embodiment, with reference to Fig. 9, the material of the blinds 12 is elastic material.In this way, when high pressure draught blows to hundred During leaf 12, elastic deformation can occur for blinds 12, so as to increase the opening degree between two adjacent blinds 12, so as to reach pressure release Purpose.

In addition, in order to make the pressure release of blinds 12 better, in the present embodiment, with reference to Figure 10, the blinds 12 and institute Plate body 11 is stated to be flexibly connected (in such as Figure 10, the junction L of blinds and plate body, its thickness is less than the thickness of blinds itself). In this way, when blinds 12 is subject to larger airflow thrust, blinds 12 can be rotated relative to plate body 11, so that enlarged openings Degree.Certainly, if on the basis of blinds 12 and the plate body 11 flexible connection, the material of itself of blinds 12 is elastic material Material, then its pressure release effect will more preferably.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, It is every under the inventive concept of the utility model, equivalent structure made based on the specification and figures of the utility model becomes Change, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
