The specific embodiment

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

Fig. 1 and 2 be indicative icon according to the stereogram of the structure of the dust-separating appliance of the vacuum cleaner of first embodiment of the invention, 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 present embodiment: the dust separation unit 10 of dust-separating from air amount; Storage is by the dust arrester 20 of dust separation unit 10 isolated dusts; To contain the air draught of dust towards the suction guiding piece 30 of 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, the air flow suction guiding piece 30 that sucks by sucking ozzle (not shown).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 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 entrance 120 is formed on the cyclone 110 (on each side one) with air amount.This can form with at cyclone 110 interior generation cyclonic air flows about the tangential direction of cyclone 110 entrance 120.This provides the suction passage that makes air enter cyclone 110 to entrance 120.

This is connected on the both sides of allocation units 40 separately to entrance 120.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 entrance 120.

The dust export 130 of cyclone 110 interior isolated dusts discharges is formed on the middle part of cyclone 110.

Therefore, isolated dust is shifted to the middle part of cyclone 110 in the air that sucks of each entrance 120 by 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 equidirectional of rotation consistent with dust---namely along---discharges, 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 be gathered on the filter element (hereinafter will describe) less, thereby be conducive to Air Flow and improve the dust separation performance.

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 air of discharging by air outlet slit 140 can be merged into main body (not shown) 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 entrance 210 is formed on the upside of dust arrester 20.And dust export 130 is from cyclone 110 to downward-extension.

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

The bottom that lid member 220 is connected in dust arrester 20 is stored in 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 present embodiment middle cover member 220 is not limited to any ad hoc approach.

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 separation dust collector device 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.

By making the minimize weight of dust arrester 20, the user can easily move and process 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, will provide the more detailed description of 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: for generation of the body 111 of cyclonic air flow; With a counter-lateral quadrents 115, each sidepiece 115 consists of one of both sides of body 111.Sidepiece 115 parallel to each other facing.

Entrance 120 is respectively formed on the both sides of body 111.Each entrance 120 tangentially forms about cyclone 110.So the air that sucks by each entrance 120 is at one of cyclone 110 interior formation twice cyclonic air flows.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, less even cyclone 110 forms ground, but the centrifugal force that entrance 120 places 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 with air the dust separation performance of the structure same levels of a plurality of dust separation unit.So, do not need the additional dust separation unit of dust-separating from the air that dust separation unit is discharged.Yet, in the present 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 cyclonic air flow stronger than the sidepiece of entrance 120 at the middle part of cyclone 110.

So when this was joined at cyclone 110 middle parts to cyclonic air flow, the intensity of air-flow was greater than the situation that produces the 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 by 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 because of static import or the inside of dust export 130.Yet because in the present embodiment, 130 places produce powerful cyclonic air flow at dust export, so hair and other foreign material can not adhere to dust export 130, and can easily be discharged to dust arrester 20.

Outlet 116 forms passes each sidepiece 115 isolating the Bas Discharged of dust in the cyclone 110.

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 from cyclone 110 with dust separating air in the cyclone 110.

Here, do not form through hole on the securing member 152, so that the air that sucks by entrance 120 can not discharge immediately, but can circulate cyclone 110 is interior unobstructedly.

That is to say, by securing member 152, can to air amount loop guiding with at the unobstructed cyclonic air flow of cyclone 110 interior generations, thereby strengthen the 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 mentioned above, the cyclonic air flow that produces in the cyclone 110 is joined at the middle part of cyclone 110, discharges by dust export 130 by cyclonic air flow isolated dust from air.

Here, when this manufactures width (L2) less than dust export 130 to the length between the filter element 150 (L1), foreign material such as hair and thin paper can not discharged by dust export 130, and can adhere to filter element 150 or be deposited in the hole 156.In this case, air can't easily pass filter element 150, thereby causes inhalation power to weaken.

Therefore, in the present embodiment, this manufactures width (L2) greater than dust export 130 to the length between the filter element 150 (L1), so that foreign material such as hair and thin paper can all be discharged by dust export 130.

In the present embodiment as mentioned above, air sucks cyclone 110 by a plurality of entrances 120, discharges from cyclone 110 by a plurality of outlets 116 with dust separating air in cyclone 110.

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

Thereby when air was easily discharged from cyclone 110, inhalation power was strengthened conscientiously, and so that the cyclonic air flows in the cyclone 110 flow unobstructedly.

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

A pair of guiding piece 170 is formed in the cyclone 110 in case the dust that stop-pass overwinding wind flow separation goes out is shifted to outlet 116.

Particularly, guiding elements 170 forms along the interior week of cyclone 110 with continuous curvature.Guiding elements 170 is from the Axis Extension predetermined length 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, 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, the cyclonic air flow of entrance 120 places generation is along the interior Zhou Yixiang dust export 130 of 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 the other end 172 motion 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.

When cyclonic air flow exported 116 because 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 by dust export 130.

When isolated dust is prevented from shifting to outlet 116 the time, can prevent that isolated dust (specifically 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 flow guide 170 reduces gradually towards dust export 130, so the intensity of the cyclonic air flow of joining at dust export 130 places strengthened, thereby allow isolated dust easily to discharge.

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

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 can be arranged in the width of dust export 130.That is to say, at least a portion of dust export 130 is arranged between the guiding elements 170.

As mentioned above, 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 by 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 cleaning filter element 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 the curvature that has with body 111 interior Zhou Xiangtong when lid member 160 is attached to body 111.Therefore, can prevent that the cyclonic air flow in the cyclone 110 from changing because of lid member 160, and cyclonic air flow can be consistent.

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

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

The below will describe the operation of dust-separating appliance.

Fig. 6 and 7 is the cutaway views that illustrate according to the air-flow in the dust-separating appliance of the first embodiment, and wherein Fig. 6 is along the line A-A of Fig. 1 cutaway view that cut open, the diagram air-flow, and Fig. 7 is along the line B-B of Fig. 1 cutaway view that cut open, the diagram air-flow.

With reference to Fig. 6 and 7, when vacuum cleaner produced inhalation power, the air that contains dust flowed along sucking guiding piece 30.Flow through the air flow allocation units 40 of suction guiding piece 30 and be dispensed to each entrance 120 by allocation units 40.Then, the air that contains dust passes each entrance 120 and tangentially is inhaled in the both sides of cyclone 110.

To move along guiding elements 170 and to join at the middle part of cyclone 110, in this process, air is subject to different centrifugal force with dust because it varies in weight to the air that sucks, so that separate between the two along the rotation of the inner surface of cyclone 110.

Isolated dust (being illustrated by the broken lines) is discharged by dust export 130 from the middle part of cyclone 110, and the dust of discharging flows through dust export 130 and enters dust arrester 20.

In contrast, filtered by filter element 150 with dust separating air (being represented by solid line), then pass outlet 116 and discharge from cyclone 110.The air of discharging flows through corresponding air outlet slit 140, joins at converging passage 142, and the main body that enters vacuum cleaner.

Fig. 8 be diagram according to the schematic perspective view of the structure of the dust-separating appliance of the vacuum cleaner of second embodiment of the invention, Fig. 9 is the cutaway view that the line C-C along Fig. 8 cuts open.

Except the shape of dust outlet and cyclone was different, present embodiment was identical in other side with the first embodiment.Therefore, only the characteristic of present embodiment is provided description.

With reference to Fig. 8 and 9, comprise cyclone 610 according to the dust separator 60 of present embodiment, the diameter of described cyclone 610 611 increases gradually from two ends to the middle part.

And a pair of guiding elements 640 is formed on dust export 630 places.Guiding elements 640 is shaped about the middle part of dust export 630 is symmetrical.

Because cyclone 610 so forms diameter and increases gradually towards the middle part, so a pair of cyclonic air flow that produces in cyclone 610 both sides can easily be joined at the middle part.

And, because the diameter at cyclone 610 middle parts is than large at the place, two ends, so the cyclonic air flow speed of cyclone 610 center reduces, thereby reduce at the whirlpool that cyclone 610 center produce.

In addition, because this is symmetricly set in the both sides of dust export 630 to guiding elements 640, so cyclonic air flow can motion between corresponding guiding elements 640,611 join towards the middle part thereby be conducive to cyclonic air flow.

Similarly, when cyclonic air flow was easily joined at the middle part of cyclone 610, dust can easily be discharged by dust export 630.

Because the diameter of cyclone 610 increases towards the middle part, so dust export 630 is also greater than the dust export in the first embodiment.Here, the top periphery 632 of dust export 630 and lower periphery 634 form corresponding to the oblique angle of cyclone 610 at a certain angle.

Thereby when dust export 630 enlarged, the dust discharging performance was enhanced, thereby has also increased inhalation power.

And when the diameter at cyclone 610 middle parts during greater than the diameter at its place, two ends, the middle part of cyclone 610 is configured to be installed in the top of dust arrester 70.Therefore, dust arrester 70 can have the recess 701 of installation, and the middle part that described installation recess 701 forms cyclone 610 is installed on wherein.

The spirit and scope of the present invention are not limited to the embodiment here, can propose as described below other embodiment.

At first, dust arrester 20 can be arranged in the below of cyclone 110, is installed in simultaneously on the main body of vacuum cleaner, and perhaps alternately, dust arrester 20 can be arranged in the place ahead of cyclone 110.In these cases, the dust entrance of dust arrester 20 can be limited to the sidepiece of dust arrester 20, perhaps can be arranged in the top of dust arrester 20.

And when the dust entrance was limited to the sidepiece of dust arrester 20, the lid member that is used for the discharge dust can be arranged on top or the bottom of dust arrester.

As in the first embodiment, the dust entrance can be formed on the sidepiece of dust arrester, and the lid member can be arranged on the bottom of dust arrester; Perhaps alternately, the lid member can be arranged on the top of dust arrester, and the dust entrance can be formed on and cover in the member.In the latter case, the structure of dust arrester itself can be simplified.
