The specific embodiment

Below, provide detailed description according to the embodiment of the present invention with reference to accompanying drawing.

Fig. 1 and 2 is the stereogram of indicative icon according to the structure of the dust-separating appliance of the vacuum cleaner of first embodiment of the invention, and Fig. 3 is the exploded perspective view of the dust-separating appliance among Fig. 1 and 2.

Referring to figs. 1 through 3, comprise according to the dust-separating appliance 1 of the vacuum cleaner of this embodiment: the dust separation unit 10 of dust-separating from suck air; Storage is by the dust arrester 20 of dust separation unit 10 isolated dusts; To contain the suction guiding piece 30 of the air draught of dust towards dust separation unit 10 guiding; And will suck the allocation units 40 that air in the guiding piece 30 is dispensed to dust separation unit 10.

Particularly, flow to suction guiding piece 30 through sucking ozzle (not shown) inhaled air.Suck guiding piece 30 and be arranged in the vacuum cleaner, and be arranged in the below of dust arrester 20.Suck guiding piece 30 and have connected allocation units 40.

Dust separation unit 10 is isolated dust from the air that allocation units 40 are supplied with.Dust separation unit 10 usefulness cyclonic principle are isolated dust from air, and comprise the cyclone 110 that is used for this purpose.

The axis along continuous straight runs of cyclone 110 extends.So the air in the cyclone 110 vertically rotates.

A pair of inlet 120 is formed on the cyclone 110 (on each side one) to suck air.This 120 can tangentially form in cyclone 110, to produce cyclonic air flow about cyclone 110 entering the mouth.This 120 provides the suction passage that makes air get into cyclone 110 to entering the mouth.

This 120 is connected on the both sides of allocation units 40 entering the mouth separately.Therefore, flow through suck guiding piece 30 air in the shunting of the both sides of allocation units 40, and the air of shunting rises and is inhaled into cyclone 110 along separately inlet 120.

The dust export 130 of isolated dust discharge in the cyclone 110 is formed on the middle part of cyclone 110.

Therefore, shift to the middle part of cyclone 110 through isolated dust in each 120 inhaled airs that enter the mouth of cyclone 110 both sides.Then, the dust that flows to the cyclone middle part passes dust export 130 and is expelled to dust arrester 20.

Here, dust export 130 tangentially forms to allow easily to discharge dust about cyclone 110.So; Isolated dust about cyclone 110 tangentially in the cyclone 110 discharges---just along the consistent equidirectional that rotates with dust---; Thereby not only allow easily the dust of higher density to be discharged cyclone 110, and allow easily more low-density dust to be discharged cyclone 110.

Because more low-density dust can easily discharge, thus more low-density dust accumulate on the filter element (hereinafter will be described) with less, thereby help the mobile and improvement dust separation performance of air.

And, respectively form an air outlet slit 140 in the both sides of cyclone 110 to discharge the air of isolating dust in the cyclone 110.The main body (not shown) that the air of discharging through air outlet slit 140 is joined and got into vacuum cleaner at converging passage 142.

Isolated dust in the dust arrester 20 storage dust separation unit 10.Because dust arrester 20 is installed on the vacuum cleaner main body, so dust arrester 20 is communicated with dust separation unit 10.

Particularly, when dust arrester 20 was installed on the vacuum cleaner main body, dust arrester 20 was arranged in the below of dust separation unit 10.So dust inlet 210 is formed on the upside of dust arrester 20.And, dust export 130 from cyclone 110 to extending below.

Therefore, isolated dust moves downward along dust export 130 in the cyclone 110, and isolated dust can easily get into dust arrester 20.

The bottom that lid member 220 is connected in dust arrester 20 is stored in the dust in the dust arrester 20 with discharge.Lid member 220 can be attached to dust arrester 20 pivotly, and can removably be attached to dust arrester 20.The coupling method of this embodiment middle cover member 220 is not limited to any ad hoc fashion.

So dust arrester 20 is set to be independent of the parts of dust separation unit 10, and be configured to optionally be communicated with dust separation unit 10.Therefore, the user can only separate vacuum cleaner main body with dust arrester 20 and be emptied to the outside with the dust that will be stored in the dust arrester 20.

Because in dust arrester 20, be not provided for the structure of dust-separating, thus the structure of dust arrester 20 simplified, and also the weight of dust arrester 20 can minimize.

Through making the minimize weight of dust arrester 20; The user can easily move and handle dust arrester 20; And because the internal structure of dust arrester 20 is simple, so can easily dust be emptied to the outside, and the user can easily clean the inside of dust arrester 20.

Below, with the more detailed description that provides dust-separating appliance.

Fig. 4 is the cutaway view that the line A-A along Fig. 1 cuts open, and Fig. 5 is the cutaway view that the line B-B along Fig. 1 cuts open.

With reference to Figure 4 and 5, cyclone 110 comprises: the body 111 that is used to produce cyclonic air flow; With pair of side parts 115, each sidepiece 115 constitutes one of both sides of body 111.Sidepiece 115 parallel facing.

Inlet 120 is respectively formed on the both sides of body 111.Each inlet 120 tangentially forms about cyclone 110.So, in cyclone 110, form one of twice cyclonic air flow through each 120 inhaled air that enter the mouth.Cyclonic air flow is along the inner surface circulation of body 111.

So when producing a pair of cyclonic air flow in the single space, the flow of air increases, windage loss reduces, and separating property is improved.

And, when producing a pair of cyclonic air flow in the single space, cyclone can form less than the cyclone that produces single cyclonic air flow in the single space.

Here, littler even cyclone 110 forms ground, but the centrifugal force that 120 places that enter the mouth produce is greater than prior art, so improved the dust separation performance.

And, when producing a pair of cyclonic air flow in the single space, can realize passing the dust separation performance of the structure same levels of a plurality of dust separation unit with air.So, need be from the air that dust separation unit is discharged the additional dust separation unit of dust-separating.Yet, in this embodiment, additional dust separation unit can be set.

And each produces together and cyclonic air flow when flowing to the middle part in cyclone 110 both sides when a pair of cyclonic air flow, and the cyclonic air flow at middle part strengthens.Therefore, produce the stronger cyclonic air flow of sidepiece at the middle part of cyclone 110 than inlet 120.

So when this can be fashionable at cyclone 110 middle parts to cyclonic air flow, the intensity of air-flow is greater than producing the situation of single track cyclonic air flow in single space, thereby strengthened the dust separation performance.

The dust of shifting to cyclone 110 middle parts can be discharged to dust arrester 20 through dust export 130 by means of powerful cyclonic air flow, thereby can strengthen the dust discharging performance.

Hair and other foreign material can easily adhere to the import or the inside of dust export 130 because of static.Yet,,, and can easily be discharged to dust arrester 20 so hair can not adhere to dust export 130 with other foreign material because in this embodiment, 130 places produce powerful cyclonic air flow at dust export.

Outlet 116 forms passes each sidepiece 115 so that the air of isolating dust in the cyclone 110 is discharged.

And filter element 150 is attached to each outlet 116 to filter the air of being discharged.Particularly, filter element 150 disposes: the tubular securing member 152 that is fastened to cyclone 110 inside; With the conical filter 154 that extends with filtered air from securing member 152.And, in filter 154, be formed with a plurality of holes 156 so that air passes.

Therefore, pass a plurality of holes 156 and pass through outlet 116 discharges with dust separating air in the cyclone 110 from cyclone 110.

Here, do not form through hole on the securing member 152, make and can not discharge immediately, but can in cyclone 110, circulate unobstructedly through 120 inhaled airs that enter the mouth.

That is to say, through securing member 152, can be to the circulation channeling conduct that sucks air cyclone 110 in, producing unobstructed cyclonic air flow, thus enhancing dust separation performance.

Be arranged in the cyclone this and can manufacture width (L2) greater than dust export 130 to the length between the filter element 150 (L1).

Particularly, as stated, the cyclonic air flow that produces in the cyclone 110 is joined at the middle part of cyclone 110, discharges through dust export 130 through cyclonic air flow isolated dust from air.

Here, when this manufactures the width (L2) less than dust export 130 to the length between the filter element 150 (L1), can not discharge, and can adhere to filter element 150 or be deposited in the hole 156 through dust export 130 such as foreign material such as hair and thin papers.In this case, air can't easily pass filter element 150, weakens thereby cause being pumped into power.

Therefore, in this embodiment, this manufactures the width (L2) greater than dust export 130 to the length between the filter element 150 (L1), makes can all discharge through dust export 130 such as foreign material such as hair and thin papers.

As stated, air sucks cyclone 110 through a plurality of inlets 120 in this embodiment, in cyclone 110, discharges from cyclone 110 through a plurality of outlets 116 with dust separating air.

So the air that sucks cyclone 110 through corresponding inlet 120 is discharged through corresponding outlet 116, thereby allows easily to discharge air.

Thereby when air easily when cyclone 110 is discharged, inhalation power is strengthened conscientiously, and makes the unobstructed flows of cyclonic air flow in the cyclone 110.

And even when dust accumulation makes that air can't flow easily on such filter element, air can be discharged through another filter element, thereby prevents that the air inhalation power is impaired suddenly.

A pair of guiding piece 170 is formed in the cyclone 110 to prevent shifting to outlet 116 through the isolated dust of cyclonic air flow.

Particularly, guiding elements 170 with continuous curvature along interior week of cyclone 110 and form.Guiding elements 170 is from the axis definite length extended of the interior circumferential cyclone of cyclone 110.

And guiding elements 170 extends to dust export 130 interior week from cyclone 110.That is to say that the cross section of guiding elements 170 is formed with predetermined slant.Therefore, the diameter of an end 171 of each guiding elements 170 is greater than its other end 172.Especially, guiding elements 170 forms diameter and narrows down gradually towards dust export 130 from exporting 116.

Here, cyclonic air flow that 120 places produce the interior Zhou Yixiang dust export 130 that enters the mouth along cyclone 110.When the diameter of guiding elements 170 when dust export 130 diminishes gradually, cyclonic air flow by inside skewed surface 173 guiding of guiding elements 170 easily to flow to dust export 130.

In contrast, when cyclonic air flow during towards 172 motions of the other end of guiding elements 170, cyclonic air flow flowed between the interior week of the outer ramp 174 of guiding elements 170 and cyclone 110, and was prevented from flowing to and exports 116.

Thereby when cyclonic air flow exported 116 because of guiding elements 170 is prevented from flowing to, isolated dust was prevented from shifting to outlet 116.Therefore, isolated dust circulates between each guiding elements 170, and can all discharge through dust export 130.

When isolated dust is prevented from shifting to outlet 116 the time, can prevent that isolated dust (particularly be such as thin paper etc. than bigger material) from stopping up the hole 156 of filter element 150, weakens so can prevent the inhalation power of air.

In addition, because the diameter of guide of flow member 170 reduces towards dust export 130 gradually,, thereby allow isolated dust easily to discharge so the intensity of the cyclonic air flow of joining at dust export 130 places is able to enhancing.

So each guiding elements 170 can guide cyclonic air flow flowing to dust export 130 from exporting 116 unobstructedly in this embodiment, and, cyclonic air flow allows cyclonic air flow circulation between corresponding guiding elements 170 when shifting to dust export 130.

Here, in order to allow easily to discharge along the dust that the outer ramp 174 of each guiding elements 170 flows, an end 172 of each guiding elements 170 is arranged in the width of dust export 130.That is to say that at least a portion of dust export 130 is arranged between the guiding elements 170.

As stated, when an end 172 of each guiding elements 170 was arranged in the width of dust export 130, the dust on the outer ramp 174 of each guiding elements 170 can not discharged through dust export 130, and is prevented from continuing circulation along guiding elements 170.

Opening 112 is formed on the body 111 of cyclone 110 allowing and changes and clean filtering member 150.Opening 112 is opened and is sealed by means of lid member 160.Containment member 114 is arranged on the attachment areas place of opening 112 and lid member 160.

Here, the inner surface of lid member 160 can form lid member 160 have when being attached to body 111 with body 111 in the curvature of Zhou Xiangtong.Therefore, prevented that the cyclonic air flow in the cyclone 110 from changing because of lid member 160, and cyclonic air flow is able to consistent the maintenance.

And, because lid member 160 removably is attached to cyclone 110,, the user cover member 160 easily changing filter element 150 so can dismantling, and the inside of clean filtering member 150 and cyclone 110 easily.

The dust compartment 202 that is used to store dust is limited in the dust arrester 20, and dust inlet 210 is limited to the top of dust arrester 20.And the containment member 212 that is used to be sealed in the contact area between dust inlet 210 and the dust export 130 is arranged on dust and enters the mouth 210.Here, containment member 212 also can be arranged on the dust export 130.
