The present invention proposes a kind of air fairing, with reference to Fig. 1, Fig. 5 and Fig. 6, this air fairing comprises stop component 1 and air-duct spiral case 2, the tubular wine wheel 10 of air-conditioner is equipped with in air-duct spiral case 2, this air-duct spiral case 2 comprises the lower frame 21 and upper side frame 22 that form air-conditioned wind tunnel, the air outlet W that the air-flow that the tubular wine wheel 10 of air-conditioner is introduced is guided to air channel by air-duct spiral case 2 flows out, stop component 1 comprises multiple wind guide strip 11, wind guide strip 11 is disposed on lower frame 21 near air outlet place, between two wind guide strips 11, one end of cell body is inner towards air-duct spiral case 2.
Tubular wine wheel 10 is installed on its inside by air-duct spiral case 2, the inwall of air-duct spiral case 2 carries out drainage (as shown in Fig. 1 air current flow direction F) to tubular wine wheel 10 from the air-flow of extraneous suction, the circulation of major part air-flow is flowed out to air conditioner wind outlet W, and fraction air-flow enters the airflow circulating in air-duct spiral case 2 again from the whirlpool tongue walking around upper side frame 22 end.Stop component 1 is arranged on lower frame 21 near air outlet W place, and namely stop component 1 is arranged on the air-out direction of air-conditioner, and the cross section of the wind guide strip 11 of this stop component 1 can be arbitrary shape, such as square, outer convex, indent arc etc.Wind guide strip 11 is arranged at intervals at lower frame 21 towards on the side of upper side frame 22, and the gap between two wind guide strips 11 forms a cell body, and one end of this cell body is inner towards air-duct spiral case 2, namely the bearing of trend of cell body and the air-out direction of air-conditioner roughly the same.Multiple wind guide strip 11 interval arranges formation stop component 1, and air fairing comprises multiple stop component 1, and this stop component 1 is distributed in lower frame two ends along its length.In addition, this stop component 1 also evenly can be located at the side of lower frame 21 towards upper side frame 22, is not limited to the two ends of lower frame 21 length direction.
In the present embodiment, by the lower frame 21 at air fairing, stop component 1 is set near air outlet W place, the one end of cell body between the wind guide strip 11 of stop component 1 is towards the inside of air-duct spiral case 2, namely basically identical (bearing of trend and air-out direction angle are less than preset value for the bearing of trend of this cell body and air-out direction, such as preset value is 30 degree), reduce the air-out cross section of air outlet W, the local lifting flow velocity of eluting gas, use pneumatic pressure to strengthen, thus air-out dynamic pressure is larger just can overcome larger airflow reflux static pressure, thus suppress the outer gas backstreaming of air outlet W in air outlet W, and then inhibit pulsation surge sound, thus solve the technical problem of air-conditioner appearance pulsation surge sound.Simultaneously, to arrange and towards the wind guide strip 11 of air-duct spiral case 2 inside because stop component 1 comprises multiple interval, the air-flow of air-conditioner blowout flows through from the cell body between two wind guide strips 11, when air-conditioner is in refrigerating state, because cold airflow flows through from the cell body between wind guide strip 11, namely wind guide strip 11 all has the little cold airflow of temperature difference to flow through along the both sides of air-out direction, so wind guide strip 11 is little along the temperature difference of the both sides of air-out direction, thus prevent from condensation appears in wind guide strip 11, thus by while arranging stop component 1 and suppressing pulsation surge sound, also solve stop component 1 and occur condensation problem because keeping out the wind.
In addition, with reference to Fig. 5, stop component 1 is fixedly connected with lower frame 21 or one-body molded, namely stop component 1 directly can be fixedly connected on the two ends of lower frame 21 length direction, or stop component 1 structure is directly accomplished on mould, when injection moulding lower frame 21 in the lump by stop component 1 injection mo(u)lding, be convenient to simplified manufacturing technique, enhance productivity.
Further, with reference to Fig. 1 and Fig. 3, wind guide strip 11 is curved bars, the curved portions 112 that this wind guide strip 11 comprises the line part 111 parallel with air conditioner air-out direction and is connected away from tubular wine wheel 10 one end with this line part 111.
Curved portions 112 is one-body molded with line part 111, because line part 111 is consistent with air conditioner air-out direction, cell body bearing of trend between the line part 111 of two interval wind guide strips 11 is also consistent with air conditioner air-out direction, more be conducive to air-conditioner to puff away the cell body flow between two wind guide strips 11, reduce the blocking effect of stop component 1 pair of air-out air-flow; Simultaneously, between the curved portions 112 of two interval wind guide strips 11, the cell wall of cell body is arcwall face, this cell wall is that the cell body of arcwall face has good drainage to air-out air-flow, it is more mild that the air-flow that this arcwall face cell wall makes air outlet W blow out changes direction change in flow that is more soft, that blow out air-flow, avoids occurring abnormal sound because sharply changing through air outlet W blowout air-flow velocity.
Preferably, with reference to Fig. 3, the cross-sectional width of line part 111 is less than the cross-sectional width minimum of a value of curved portions 112, because parallel between wind guide strip 11 and interval is arranged, the curved portions 112 of wind guide strip 11 is more away from its line part 111, the cross-sectional width of curved portions is larger, namely the cell body line part 111 between two wind guide strips 11 become partial width larger, curved portions 112 become partial width less, and cell body width is reduced to curved portions 112 end gradually by line part 111, between two wind guide strips 11, the inlet area of cell body is greater than discharge area, thus when air-conditioner is run, the air-flow of blowout can smoothly from stop component 1 one end windward to leeward one end, and be greater than discharge area due to the inlet area of the air-flow of cell body between two wind guide strips 11, thus the flow velocity flowing through wind guide strip 11 air-flow can be promoted, its dynamic pressure is strengthened, and air-out dynamic pressure is larger just can overcome larger airflow reflux static pressure, reduces the airflow reflux of air-conditioner blowout further.
Further, with reference to Fig. 4, curved portions 112 comprises the windward side cambered surface A1 and leeward side cambered surface A2 that are oppositely arranged, the curvature of windward side cambered surface A1 is greater than the curvature of leeward side cambered surface A2, namely the windward side cambered surface A1 of curved portions 112 becomes θ 1 away from the molded line tangent line of tubular wine wheel 10 one end with air-out direction, the leeward side cambered surface A2 of same curved portions 112 becomes θ 2 away from tubular wine wheel 10 one end molded line tangent line with air-out direction, and θ 1> θ 2, and the scope of θ 1 is 0 degree to 90 degree.When air conditioner air-out, the air flow energy idol flowing through stop component 1 is smooth and easy to be passed through, wind is directed to the leeward side cambered surface A2 of adjacent wind guide strip 11 by the windward side cambered surface A1 of wind guide strip 11, under cooling situations, wind guide strip 11 both sides cold airflow flow is suitable, wind guide strip 11 both sides temperature difference is less, thus weakens further and even eliminate wind guide strip 11 leeward side cambered surface A2 and occur condensation.
Preferably.Wind guide strip 11 setting parallel to each other, spacing between line part 111 is greater than the spacing between curved portions 112, namely and oppositely do straight line away from the end points of tubular wine wheel 10 along air-out direction by a wind guide strip 11 windward side cambered surface A1, the leeward side cambered surface A2 of this straight line wind guide strip 11 adjacent with this wind guide strip 11 has intersection point.
When air conditioner wind outlet W place's local return, because the spacing between line part 111 is greater than the spacing between curved portions 112, the i.e. air-flow of backflow relatively, between two adjacent curved portions 112 cell body become the area of reflux inlet be less than cell body between corresponding two adjacent line parts 111 become the area of bypass outlet, inhibit reflux airflow to enter air outlet W from stop component; Meanwhile, the air-flow that the reflux inlet that two adjacent curved portions 112 are formed enters can directly be beaten on leeward side cambered surface A2, thus suppresses in the gas backstreaming air intake vent W outside air outlet W.
Further, see figures.1.and.2, based on the low regime S of angle determination air-conditioner on this lower frame 21 of lower frame 21 and upper side frame 22, wind guide strip 11 is arranged in the S of this low regime.
Low regime S is distributed in the side of lower frame 21 towards upper side frame 22 near air outlet W place, and formed by the lower frame 21 of low regime S and air-duct spiral case 1 and upper side frame 22, angle is relevant, and the scope of this angle larger then low regime S is larger.Particularly, by probe velocimetry on lower frame 21, the particularly two ends of lower frame 21 length direction, air-out direction on detection draw low regime S (gas flow rate is less than preset value and is called low speed), wind guide strip 11 is arranged in the S of this low regime, and preferably, the coverage of wind guide strip 11 is slightly larger than the coverage of low regime S, thus the air-flow of wind guide strip 11 couples of low regime S raises speed comprehensively, guarantee can not reflux after flowing through all air-flows outflow air outlet W of low regime S further.
Preferably, with reference to Fig. 2, the low regime S region that is vertical line positive and negative 15 degree of institutes eccentric on lower frame 21 radiation, this eccentric vertical line be with the center O of the eccentric vortex of air-conditioned wind tunnel be basic point, the vertical line done to lower frame place plane.Adopt this scheme, stop component 1, to the gas flow speeding best results flowing through low regime S, is eliminated or alleviates surge phenomenon the best.
In addition, with reference to Fig. 5, stop component 1 is fixedly connected with lower frame 21 or one-body molded, namely stop component 1 directly can be fixedly connected on the two ends of lower frame 21 length direction, or stop component 1 structure is directly accomplished on mould, when injection moulding lower frame 21 in the lump by stop component 1 injection mo(u)lding, be convenient to simplified manufacturing technique, enhance productivity.
The present invention also proposes a kind of air-conditioner, this air-conditioner is preferably Split wall-mounted type air conditioner, with reference to Fig. 1, air-conditioner comprises above-mentioned air fairing and tubular wine wheel 10, tubular wine wheel 10 is arranged in the air-duct spiral case 2 of this air fairing, and this tubular wine wheel 10 is introduced the air outlet W that external air flow is drained to by air-duct spiral case 2 air channel that the upper side frame 22 of this air-duct spiral case 2 and lower frame 21 are formed and blown out.Because this air-conditioner have employed the above-mentioned whole technical schemes leading all embodiments of air fairing, therefore, all beneficial effects that the technical scheme at least with above-mentioned air fairing embodiment is brought, this is no longer going to repeat them.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every under inventive concept of the present invention; utilize the equivalent structure transformation that description of the present invention and accompanying drawing content are done, or directly/be indirectly used in other relevant technical fields to include in scope of patent protection of the present invention.
