Description

The draining pump impeller

Technical field:

The utility model relates to a kind of member that is used for the draining pump on the air conditioner, especially relates to a kind of draining pump impeller.

Background technique:

Air conditioner is when refrigerating operaton, and airborne moisture content is understood condensation and attached on the heat exchanger, is dropped in then in the water pond that is arranged at the heat exchanger below.For the condensed water that accumulates in this water pond is drained, air conditioner all is equipped with draining pump.The main structure of common use in refrigeration system draining pump as shown in Figure 1, this draining pump is made up of motor 10, upper pump casing 20, impeller 30 and lower pump body 40, impeller 30 is located in the pump housing shell that upper pump casing 20 and lower pump body 40 closures form, impeller 30 with pass upper pump casing 20 on through hole motor 10 the axle be connected, and in pump case, rotated freely by the driving of motor 10, the bottom of lower pump body 40 is provided with water intake 41, and the side is provided with water outlet 42.When draining pump is worked, 30 rotations of motor 10 drives impeller, the condensed water that amasss in water pond is inhaled into water intake 41, and since the effect of inertia that impeller 30 drives and in the pump housing on rise, be subjected to centrifugal action from the water outlet 42 of lower pump body 40 sides, to give off the outside at last.

Impeller 30 is the vital parts in the draining pump, what Fig. 2 and Fig. 3 represented is the structural drawing of common used impeller 30, illustrated impeller 30 has center axial region 1 ', it is the obconic disk 2 ' of peripheral wall 6 ' for hollow portion, periphery that its intermediate section is provided with central authorities, the top of this disk 2 ' be provided with alternate and from center axial region 1 ' to around be the plate shaped big blade 3 ' and the auxiliary blade 5 ' of radial arrangement, big blade 3 ' is connected between center axial region 1 ' and the disk 2 ', and the below of disk 2 ' is provided with the plate shaped small leaf 4 ' that joins with big blade 3 '.

In actual drainage procedure, impeller 30 commonly used is by the rotation stirring of small leaf 4 ' and big blade 3 ' water to be drawn to elevate, and disk 2 ' only plays impermeable role, thereby uses the draining pump flow and the lift of said structure impeller 30 all limited, and drainage efficiency is not high yet.

Summary of the invention:

Technical problem to be solved in the utility model is to overcome the lift underfed that existing draining pump causes because of blade wheel structure, the defective that drainage efficiency is not high, provide a kind of current castering action significantly, lift and the big draining pump impeller of flow.

The technical scheme in the invention for solving the technical problem is as follows:

A kind of draining pump impeller, include the center axial region, around the peripheral wall in axle center, some by axle center outwards radial big blade and small leaf and the auxiliary blade between each big blade, it is characterized in that: also be provided with guide plate in the cavity between described each big blade, auxiliary blade and peripheral wall, this guide plate extends from bottom to up along the reverse planar in the shape of a spiral around the axle center of impeller rotation.

The guide plate of draining pump impeller described in the utility model is connected with adjacent big blade or auxiliary blade in the lower end, perhaps leaving certain gaps uncovered by the economic plan between its lower end and adjacent big blade or the auxiliary blade; The outer circumferential face of peripheral wall can be stretched out in the outer end of described big blade and auxiliary blade.

Compare with existing draining pump impeller, the utility model has substituted disc structure with guide plate, and the guide plate that rises of face can be strengthened castering action to current in the draining pump working procedure in the shape of a spiral, thereby strengthen lift and flow, improve drainage efficiency, help reducing the power of motor, the miniaturization of realization motor.

Embodiment:

Now the utility model is described in further detail with specific embodiment in conjunction with the accompanying drawings.

At first see also Fig. 4 structural drawing of the present utility model.Diagram draining pump impeller includes center axial region 1, peripheral wall 6, big blade 3, small leaf 4, auxiliary blade 5 and guide plate 2; Described center axial region 1 is positioned at the axle center place of draining pump impeller, joins with the motor shaft of draining pump; Described peripheral wall 6 is one around draining pump impeller axle center, the i.e. annulus of center axial region 1; Described big blade 3 and small leaf 4 are along the axial distribution of center axial region 1 and interconnective plane tabular blade, its by the axle center to around be radial arrangement, quantity is generally 4, and this big blade 3 is connected between center axial region 1 and the peripheral wall 6, and small leaf 4 is connected in the lower end of big blade 3; Described auxiliary blade 5 also is the plane tabular blade, its respectively between each big blade 3, and similarly to around be radial arrangement, the outer end of this auxiliary blade 5 and peripheral wall 6 are joined; Described guide plate 2 is arranged in the cavity between above-mentioned each big blade 3, auxiliary blade 5 and the peripheral wall 6, and this guide plate 2 is planar in the shape of a spiral, and its reverse (is the reverse of motor rotation, see among Fig. 4 shown in the arrow A) along the impeller rotation is extended from bottom to up around the axle center; The outer end of guide plate 2 and peripheral wall 6 are joined and are inner unsettled, and its upper end joins with big blade 3 or auxiliary blade 5, in the embodiment shown in fig. 4, and leaving certain gaps uncovered by the economic plan 7 between the lower end of guide plate 2 and adjacent big blade 3 or the auxiliary blade 5.

Fig. 5 is another embodiment's of the utility model a structural perspective.The structure with embodiment illustrated in fig. 4 is identical basically for the main structure of diagram draining pump impeller, its include equally center axial region 1, around the peripheral wall 6 in axle center, some by the axle center outwards radial big blade 3a and small leaf 4, between each big blade 3a auxiliary blade 5a and be arranged at guide plate 2a in the cavity between each big blade 3a, auxiliary blade 5a and the peripheral wall 6, this guide plate 2a extends from bottom to up along the reverse planar in the shape of a spiral around the axle center of impeller rotation.With embodiment illustrated in fig. 4 different be, the outer circumferential face of peripheral wall 6 is all stretched out in the big blade 3a of draining pump impeller shown in Figure 5 and the outer end of auxiliary blade 5a, the lower end of described in addition guide plate 2a is connected with adjacent big blade 3a or auxiliary blade 5a, and does not have breach.

Draining pump impeller described in the utility model is rotated (see figure 4) by the draining pump motor driving when work, after stirring, the small leaf 4 that current are rotated is promoted in the cavity between center axial region 1 and the peripheral wall 6, because guide plate 2 is helicoid shape from bottom to top, so strengthened castering action to current, therefore improve drainage efficiency, increased draining lift of pump and flow, also reduce simultaneously the power consumption of motor, helped the miniaturization of motor.The alternative existing impeller of the utility model is applied in the draining pump of all suspended ceilings, air-conditioning such as concealed.
