Description

Discharging blades

Technical field

The utility model is relevant with drainage means, is meant a kind of more quiet Discharging blades of draining that makes especially.

Background technique

Shown in Figure 7, be that TaiWan, China announces the 566th, No. 520 " air-conditioning equipment is helped the Pu with draining " novel patent case, wherein, its impeller 90 that pumps up water has a core 91, and one disk body 92 be located on this core 91, this has some blades above disk body, then have some whole laminas 94, half vane and small leaf below, and respectively this whole lamina 94 is slightly L-shaped cones that are connected in this disk body 92 and this core 91 belows, and by finding out among the figure, the straight section outer rim that its whole lamina 94 extends downwards is to be skewed, can strengthen blade area by this, make draining more quick.

Yet, the structure of the aforementioned existing impeller 90 that pumps up water, still have in the use noise bigger between topic; Its reason is: as shown in Figure 8, be to show that the impeller 90 that pumps up water cooperates the state of being located in a volute chamber, wherein, because this whole lamina 94 is bigger, therefore produced drainage effect faster, still, but during draining in the early stage, produce noise because of water displacement is excessive; In addition, during draining in the early stage, water and bubble are to be discharged to the water outlet of this volute chamber by the edge of these existing impeller 90 belows of pumping up water, and constantly are subjected to stirring, colliding of blade in the process of advancing, and therefore also can produce bigger noise and vibration.

Because above-mentioned shortcoming, so the present utility model people is through after constantly studying and testing, and generation of the present utility model is just arranged eventually.

The model utility content

Main purpose of the present utility model is to provide a kind of Discharging blades, the noise when it can reduce draining.

Of the present utility model time a purpose is to provide a kind of Discharging blades, and it can reduce vibration.

A kind of Discharging blades of the utility model, mainly has an axis, the position, stage casing of this axis has by an impeller that extends radially outwardly, this impeller have plural hollow part with this middle between centers, one enclosure wall is formed at this impeller periphery, this impeller top surface has plural upper blade, this upper blade is radially to extend to this axis by this enclosure wall respectively, this impeller bottom surface has plural number full leaf down, plural number is the straight leaf and the plural second half down, wherein, the full leaf of this time is radially to extend to this axis by this enclosure wall respectively to form a crosspiece, and extends to form a straight section of predetermined width downwards along this axis, and this straight section and this crosspiece are perpendicular.

Described Discharging blades, wherein: this impeller is to be made progress extension outward and formed funnel-like by mediad.

Described Discharging blades, wherein: section is to form a upper coarse and lower fine cone at the bottom of this axis.

Described Discharging blades, wherein, the top of this this cone is to be higher than this impeller wheel body.

Described Discharging blades, wherein: the straight leaf of this time is radially to extend to this axis by this enclosure wall respectively.

Described Discharging blades, wherein: this second half is radially to extend to this hollow part by this enclosure wall.

Described Discharging blades, wherein: this enclosure wall root edge outside is with chamfered.

Described Discharging blades, wherein: this enclosure wall is connected in this impeller periphery with its position, stage casing.

In order to describe structure of the present utility model and characteristics place in detail, lift a following preferred embodiment now and cooperate graphic explanation as back:

Embodiment

Extremely shown in Figure 5 as Fig. 1, a kind of Discharging blades 10 that the utility model first preferred embodiment is provided, mainly has an axis 11, this 11 end of axis section is to form a upper coarse and lower fine cone 12, the position, stage casing of this axis 11 has by an impeller 14 that extends radially outwardly, this impeller 14 is to be made progress extension outward and formed funnel-like by mediad, the top of this cone 12 is to be higher than this impeller 14 to take turns body, 11 of this impeller 14 and this axis have plural hollow part 15, one enclosure wall 16 is formed at this impeller 14 peripheries with its position, stage casing, surround shape and all form in these impeller 14 upper and lowers, the root edge outside of this enclosure wall 16 is with chamfered, these impeller 14 end faces have plural upper blade 141, this upper blade 141 is radially to extend to this axis 11 by this enclosure wall 16 respectively, these impeller 14 bottom surfaces have plural number full leaf 142 down, plural number is the straight leaf 146 and the plural second half 147 down, wherein, the full leaf 142 of this time is radially to extend to this axis 11 by this enclosure wall 16 respectively to form a crosspiece 143, and extend to form a straight section 144 of predetermined width downwards along axis 11, this straight section 144 is perpendicular with this crosspiece 143, the straight leaf 146 of this time is radially to extend to this axis 11 by this enclosure wall 16 respectively, and this second half 147 is radially to extend to this hollow part 15 by this enclosure wall 16.

Please consult Fig. 6 again, the utility model is to cooperate in the drainage means 71 when using, and this drainage means 71 has a volute chamber 72, the utility model 10 is to be placed in this volute chamber 72, and these drainage means 71 1 sides have a water outlet 74 and are communicated in this volute chamber 72; Wherein, during draining in the early stage, the utility model 10 entrys into service, by water being concentrated on these impeller 14 belows by this enclosure wall 16, unnecessary water can be discharged by this water outlet 74, then, after water level was gradually high, impeller 14 belows promptly were full of water, and water is to form vortex and bubble is concentrated and can't be residual, so far, these impeller 14 belows promptly do not have bubble, and water level continue to raise and gradually be positioned at impeller 14 tops, and bubble is also because the relation of vortex and can't be residual, form the effect of the common draining of impeller 14 upper and lowers, when reaching certain water level (being the lift equinoctial point), promptly form balance draining up and down, to reach the effect of the quiet draining of normality, and also thereby vibration is reduced, and simultaneously, by more straight by straight section 144 angles of full leaf 142 under these, its gradient is less than prior art, the straight section of full leaf 142 down therefore of the present utility model is existing for little, more can not produce drainage noise during draining in the early stage; In addition, the chamfered in this enclosure wall 16 root edges outside also can make current through out-of-date more smooth and easy.

As from the foregoing, the utility model has the advantage of:

One, noise is littler: the straight section design by by this enclosure wall and the full leaf of this time, can reduce row Noise during water, in addition, this formed chamfering in enclosure wall root edge outside also makes current through more out-of-date Along just smooth, also can reduce the generation of noise, bubble.

Two, vibration is littler: the utility model has significantly reduced the residual chance of bubble, relatively also reduces Blade act on the chance of bubble, not only reduce noise, also significantly reduce blade and act on bubble The time vibration that produces.
