Description

Blower and impeller thereof

Technical field

The utility model relates to a kind of impeller, refers to a kind of impeller that is applied to blower especially.

Background technique

General existing blower can be divided into single face wind input type blower and two-sided wind input type blower.With regard to single face wind input type blower, its impeller all adopts the impeller of one-sided blade uniform distribution type, that is shown in Figure 1A and B, all blades 11 of this impeller all are arranged at a side of a stationary plane 12, is driven this impeller rotation by this stationary plane of motor driven.Yet, the impeller of this type has following shortcoming: (1) improves its blast characteristic as desire, the quantity that certainly will will increase blade in the impeller is to increase blast, but be subject to impeller size size and space, its blade is accelerated and is still had certain limit, and therefore difficulty has breakthrough improvement on the blast characteristic; (2) this impeller in the running air-flow can owing to hurriedly dwindling suddenly, be easy to generate great sinuous flow and noise by the minimum distance of air intake and blade and housing 13 from very big space.

In addition, then shown in Fig. 2 A and B, this impeller comprises a plurality of blades to another kind of existing blower, and these a plurality of blades 21 are to be divided into the both sides of a main shaft annulus 22, to reduce noise to the mode of inserting.Though under the situation of size constancy, its blade quantity can have more one times by more above-mentioned impeller,, can reduce the work done area and hinder the air communication mistake owing to increase by an annulus, so air pressure air flow there is certain loss to improve its blast characteristic.

Summary of the invention

Main purpose of the present utility model is to provide a kind of blower and impeller thereof, and it not only has the performance that increases blast and air quantity, also can reduce noise.

According to conception of the present utility model, this impeller comprises a vane group, and it is made of a plurality of flabellum; And a plurality of rakes, be connected with each flabellum of this first vane group respectively.

In addition, this impeller also comprises a basal disc, is located on it with a plurality of flabellums that this vane group is provided.The structure that this basal disc, this vane group and a plurality of rake are formed in one.This basal disc has a central opening, is arranged at wherein so that a motor that orders about this wheel rotation to be provided.Preferably, a plurality of flabellums of this vane group partly protrude in outside this basal disc bottom.

In addition, this impeller also comprises a ring portion, is located on the top outer rim of this rake.

According to another conception of the present utility model, this vane group and a plurality of rake can be arranged in many levels alternately, to increase the blast of its air-guiding.A plurality of flabellums of this vane group can be respectively the structure of a curved face type, slope surface, cabochon or plane.

According to another conception more of the present utility model, this impeller comprises one first vane group, and it is made of a plurality of flabellum; One second vane group, it is made of a plurality of flabellum; And a plurality of rakes, be connected between each flabellum of this first vane group and this second vane group.Wherein a plurality of flabellums of this first vane group and second vane group are arranged in interlaced mode respectively.

The utility model also provides a kind of blower, comprising: a housing; And an impeller, being arranged in this housing, it comprises: one first vane group, it is made of a plurality of flabellum; One second vane group, it is made of a plurality of flabellum; And a plurality of rakes, be connected between each flabellum of this first vane group and this second vane group.

The utility model has the advantages that: impeller of the present utility model can be applicable to single face wind input type blower or two-sided wind input type blower.The pluses and minuses of the comprehensive prior art of the utility model and being improved link up and down two partly flabellums with the inclined-plane, not only can increase fan performance, and can reduce noise.

Embodiment

See also Fig. 3, it is the schematic perspective view of blower of the present utility model.This blower 3 comprises that a housing 32 and is arranged at the impeller 31 in this housing.This housing can be made of a base and a loam cake.In addition, this impeller 31 comprises one first vane group 311, and it is made of a plurality of flabellum; One second vane group 312, it is made of a plurality of flabellum; And a plurality of rakes 313, be connected between each flabellum of this first vane group and this second vane group, shown in Fig. 4 A.

In this embodiment, a plurality of blades of this first vane group and second vane group are arranged in interlaced mode, shown in Fig. 4 B.Perhaps, also can be arranged in many levels alternately,, so can under the constant situation of impeller size, significantly increase the quantity of blade, with its blast characteristic of effective raising to increase the blast of its air-guiding.And a plurality of blades of this first vane group and second vane group can be the structure of a curved face type, slope surface, cabochon or plane, and the material of being formed can be the material of plastics, metal or other specific use.

This impeller also comprises a basal disc 314, is located on it with a plurality of flabellums that this first vane group and second vane group are provided.This basal disc 314 has a central opening 315, is arranged at wherein so that a motor that orders about this wheel rotation to be provided, and a plurality of blades of this first vane group and second vane group partly protrude in outside this basal disc bottom.In addition, this impeller also comprises a ring portion 316, is arranged at the top outer rim of a plurality of flabellums of this first vane group, to strengthen the structure of this impeller.This basal disc, this first vane group, this second vane group and a plurality of rake can one-body molded mode be made.

In addition, see also Fig. 5, it shows aforementioned second kind of existing blower and the comparative result of blower of the present utility model on the blast characteristic.By finding out among the figure that impeller design of the present utility model is that annulus is removed, change with the inclined-plane and be connected between two flabellums to increase the work done area, blast and wind flow can be significantly improved, and the generation of noise can be reduced.

Impeller of the present utility model is except can be as the above-mentioned embodiment, also can be designed to structure as shown in Figure 6, it includes only a vane group with different being in this impeller of the foregoing description, and a plurality of rakes are connected with each flabellum of this vane group respectively, its blast and wind flow characteristic are also close with the foregoing description.

Described above comprehensive, impeller of the present utility model can be applicable to single face wind input type blower or two-sided wind input type blower.The pluses and minuses of the comprehensive prior art of the utility model and being improved link up and down two partly flabellums with the inclined-plane, not only can increase fan performance, and can reduce noise.

So the utility model can be appointed by those skilled in the art and executed that the craftsman thinks and be to modify as all, right neitherly take off the scope that the utility model is protected.
