Abstract
The utility model relates to an air conditioner. Counterflow generated by a part of wind inflowing from a bell mouth to flow to an interstice between the front end of the bell mouth and a multi-blade fan after flowing along the inner surface of the bell mouth can be prevented through arranging a bulge for regulating the direction of suction wind on the inner side of a suction port (the bell mouth) of a blowing passage, and the rising of the noise caused by the vibration and the descending of the flow characteristic are prevented.
Description
Technical field
The utility model relates to the air-supply path of air conditioner, particularly be the air-supply path of multi blade fan.
Background technology
With reference to description of drawings air conditioner air-supply path in the past.The air-supply path of air conditioner was in the past, as shown in Figure 2, be that underframe shell portion 2 and the multi blade fan cover 3 that forms by encasing multi blade fan 1 constitutes, simultaneously each suction inlet of underframe shell portion 2 and multi blade fan cover 3 (below, be called horn mouth 4) cross sectional shape be as shown in Figure 6, in order to make the wind of inflow, be drawn onto glibly in the multi blade fan 1, drawn in round shape and become part curve form 4a (because the horn mouth sectional view shape of above-mentioned underframe shell portion and multi blade fan cover is identical, so the horn mouth sectional view of expression multi blade fan cover is as representative).In addition, constitute rectilinear form from suction inlet towards shape 4c, the 4d of blow-off outlet.(for example opening flat 10-185238 communique) with reference to the spy
But in the above-mentioned structure in the past, a part of wind from horn mouth 4 inflows, shown in the arrow of Fig. 7, flow along horn mouth inner face 4c, and gap 5 adverse currents between horn mouth leading section 4b and multi blade fan 1, institute is so that noise increases and reduces discharge characteristic, and its result causes the deterioration of wind pushing performance.In addition, constitute rectilinear form towards the shape 4c that blows out oral-lateral, 4d, do not carry out especially to improving the research of wind pushing performance from sucking oral-lateral.
The utility model content
The utility model is in order to solve above-mentioned problem, and its purpose is to improve the wind pushing performance of air conditioner air-supply path.
In order to solve above-mentioned problem, the utility model is at the underframe that forms air-supply path suction inlet (horn mouth) and the inside part of multi blade fan cover, is provided with the projection that is used to adjust the direction that sucks air.
By said structure, can prevent to produce adverse current by the wind that air-supply path suction inlet sucks, can reduce the flow resistance of sucking-off side, its result improves wind pushing performance.

The specific embodiment
Below, with reference to description of drawings embodiment of the present utility model.
Fig. 1 represents the overall structure of air conditioner of the present utility model, and Fig. 2 is the underframe shell portion of above-mentioned air conditioner and the oblique view of multi blade fan cover.Fig. 3 is the horn mouth sectional view of above-mentioned underframe shell portion and multi blade fan cover.
As shown in the figure, the air conditioner of this embodiment is provided with the underframe shell portion 2 that encases multi blade fan 1 and be shaped at underframe 8, and multi blade fan cover 3 is installed and formation air-supply path.Multi blade fan 1 constitutes the form that sucks air from two ends, has used 2.Room air sucks from the suction grid 10 that is arranged on the front grid 9, by horn mouth 4, blows to the top of underframe 8 by multi blade fan 1, by heat exchanger (not shown), is discharged by air discharge grille 11.
The cross sectional shape of each horn mouth 4 of underframe shell portion 2 and multi blade fan cover 3, as shown in Figure 3, component part curve form 4a is successfully sucked the wind of inflow by multi blade fan 1, the blade of this horn mouth leading section 4b and multi blade fan 1 is reserved gap 5 and relatively.In addition, approximate parallel with horn mouth leading section 4b, be formed with teat 6 in above-mentioned air-supply path inboard.
Pass through said structure, shown in the arrow of Fig. 3, because prevent by projection 6, the a part of wind that flows into from horn mouth 4 produces adverse currents along the gap 5 of the mobile back of horn mouth inner face 4c between horn mouth leading section 4b and multi blade fan 1, so can prevent the increase of the noise that causes by vibration, and the decline of discharge characteristic, its result can improve wind pushing performance.
In addition, the front end of projection 6 is good more the closer to multi blade fan 1, but considers assembleability, extend to horn mouth leading section 4b on same plane.In addition, if the position of projection 6 overlaps with the circumference external diameter (the outermost circular diameter of blade) of multi blade fan 1, then wind pushing performance becomes good.
Fig. 4 is the underframe shell portion of another embodiment air conditioner of the present utility model and the oblique view of multi blade fan cover.Identical with embodiment 1,4b is parallel with the horn mouth leading section, forms projection 6 in its vicinity.The cross sectional shape of that side that the central shaft from multi blade fan 1 of projection 6 is far away becomes semicircle arcuation 6a.
By said structure, because by projection 6, after preventing to flow along horn mouth inner face 4c from a part of wind that horn mouth 4 flows into, gap 5 between horn mouth leading section 4b and multi blade fan 1 produces adverse current, make the wind that flows to along horn mouth inner face 4c simultaneously, successfully get back to the multi blade fan side along semicircle arcuation 6a, so can reduce the flow loss that produces when impacting greatly, and can prevent the rising of the noise that causes by vibration, and the decline of discharge characteristic, its result can improve wind pushing performance.
Fig. 5 is the underframe shell portion of the air conditioner of another embodiment of the present utility model and the oblique view of multi blade fan cover.As shown in Figure 5,4b is parallel with the horn mouth leading section, is formed with projection 6 in its vicinity.In addition, the suction side (horn mouth 4) by the air-supply path is designed to laterally steadily enlarging gradually to multi blade fan 1 to the hull shape shape 7 that blows out oral-lateral.
Pass through said structure, because prevent by projection 6, after a part of wind that flows into from horn mouth 4 flows along horn mouth inner face 4c and hull shape shape 7, gap 5 between horn mouth leading section 4b and multi blade fan 1 produces flows backwards, so can prevent the rising of the noise that causes by vibration, and the decline of discharge characteristic, simultaneously, because be provided with gradually steadily enlarge from the suction side (horn mouth 4) of air-supply path to the hull shape shape 7 that blows out oral-lateral, so reduce the flow resistance that blows out side, its result can further improve wind pushing performance.In addition, if projection 6 is arranged to the form of embodiment 2, will further improve performance.
Be provided for adjusting the projection of the direction that sucks wind by suction inlet (horn mouth) at the air-supply path, can prevent from a part of wind of horn mouth inflow, after flowing along the horn mouth inner face, gap 5 between horn mouth leading section 4b and multi blade fan 1 produces adverse current, so can prevent the rising of the noise that causes by vibration, and the decline of discharge characteristic, its result can improve wind pushing performance.
In addition, if make cross sectional shape one side of above-mentioned projection become the semicircle arcuation, then the wind that flows into along the horn mouth inner face along the half-circle-arc shape of projection, is got back to the multi blade fan side glibly, thus the flow loss can reduce projection greatly and impact the time.
In addition, by from the suction inlet of air-supply path to the hull shape shape that blows out side, enlarge reposefully gradually, can reduce the flow resistance that blows out side, and further improve wind pushing performance.
