The specific embodiment

Below, with reference to the accompanying drawings to being described in detail according to the embodiment of the present invention.

Fig. 1 and Fig. 2 are the stereograms of structure of the dust-separating apparatus of schematically illustrated vacuum cleaner according to first embodiment of the invention, and Fig. 3 is the exploded perspective view of the dust-separating apparatus among Fig. 1 and Fig. 2.

Referring to Fig. 1 to 3, comprise: the dust separation unit 10 that dust is separated from institute's inhaled air according to the dust-separating apparatus 1 of the vacuum cleaner of present embodiment; Dust receptacle 20 is used to store the dust of being separated by dust separation unit 10; The suction guide apparatus 30 that the air that guiding comprises dust flows towards dust separation unit 10; And the allocation units 40 that are used for the air of suction guide apparatus 30 is dispensed to dust separation unit 10.

At length, flow to suction guide apparatus 30 through suction nozzle (not shown) inhaled air.Suction guide apparatus 30 is arranged on vacuum cleaner inside, and is arranged in dust receptacle 20 belows.Allocation units 40 are connected to suction guide apparatus 30.

Dust separation unit 10 is separated dust from the air of supplying with from allocation units 40.Dust separation unit 10 utilizes cyclonic principle that dust is separated from air, and comprises the cyclone separator 110 that is used for this purpose.

On cyclone separator 110, be formed with a pair of inlet 120 (one of every side), so that air is drawn in the dust separation unit 10.This 120 can form on tangential direction with respect to cyclone separator 110 entering the mouth, so that produce cyclonic air flow in cyclone separator 110.This 120 provides the suction path that enters cyclone separator 110 for air to entering the mouth.

This is to the 120 every sides that are connected to allocation units 40 that enter the mouth.Therefore, flow to both sides by suction guide apparatus 30 flow air in allocation units 40 punishment, the air of shunting rises to be inhaled in the cyclone separator 110 along corresponding inlet 120.

Centre at cyclone separator 110 is formed with the dust export 130 that isolated dust in cyclone separator 110 is discharged.

Therefore, from the central authorities that separate and move to cyclone separator 110 via the dust that is arranged in each 120 inhaled airs that enter the mouth on cyclone separator 110 every sides by cyclonic air flow from air.Then, flow to the dust process dust export 130 of cyclone separator central authorities, and be discharged to dust receptacle 20.

Herein, dust export 130 tangentially forms with respect to cyclone separator 110, to allow easily to discharge dust.Therefore, the dust of separating in the cyclone separator 110 is tangentially discharged with respect to cyclone separator 110, that is to say, on the direction identical, discharge with the direction of dust rotation, thereby not only allow easily from cyclone separator 110, to discharge the higher dust of concentration, and allow easily to discharge the lower dust of concentration.

Because can easily discharge the lower dust of concentration, thus the lower dust of concentration will less accumulate on the filter member (following can describe), thereby help flowing and improving the dust separation performance of air.

In addition, ground of a pair of air outlet slit 140 every sides is formed on every side of cyclone separator 110, with discharge separation in the cyclone separator 110 the air of dust.The air of discharging through air outlet slit 140 converges converging path 142 places, and enters the main body of vacuum cleaner.

Dust receptacle 20 is stored in the dust of separating in the dust separation unit 10.Because dust receptacle 20 is installed on the vacuum cleaner main body, so dust receptacle 20 is communicated with dust separation unit 10.

Particularly, when dust receptacle 20 was installed on the vacuum cleaner main body, dust receptacle 20 was arranged on the below of dust separation unit 10.Therefore, dust inlet 21 is formed on the upper surface of dust receptacle 20.In addition, dust export 130 extends downwards from cyclone separator 110.

Therefore, the dust of separating in the cyclone separator 110 moves downward along dust export 130, and the dust of separating can easily enter dust receptacle 20.

Be associated with at place, the bottom of dust receptacle 20 coupling and cover member 22, be stored in the interior dust of dust receptacle 20 with discharge.Lid member 22 can pivotally be coupled to dust receptacle 20, and can be coupled to dust receptacle 20 removably.In the present embodiment, the coupling linked method of lid member 22 is not limited to any concrete grammar.

Therefore, dust receptacle 20 is set to dust separation unit 10 as independent parts, and is constructed to be permeable to optionally be communicated with dust separation unit 10.Therefore, user's dust-separating container 20 and will be stored in dust turned letter in the dust receptacle 20 only.

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

By making the minimize weight of dust receptacle 20, the user can easily carry and handle dust receptacle 20, and because the internal structure of dust receptacle 20 is simple, thus can easily it be emptied to the outside, and also the user can easily clear up the inside of dust receptacle 20.

Below, with the description more specifically that provides dust-separating apparatus.

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

Referring to Fig. 4 and Fig. 5, cyclone separator 110 comprises a body 111 and a counter-lateral quadrents 115, and body 111 is used to produce cyclonic air flow, and this counter-lateral quadrents 115 constitutes in 111 two sidepieces of body separately.Sidepiece 115 faces with each other abreast.

Inlet 120 is respectively formed on the both sides of body 111.Each inlet 120 all tangentially forms with respect to cyclone separator 110.Therefore, in cyclone separator 110, form in two cyclonic air flows one through each 120 inhaled air that enter the mouth.Cyclonic air flow is along the inner surface circulation of body 111.

Therefore, when producing a pair of cyclonic air flow in single space, the amount of flow of air increases, and windage loss reduces, and can improve separating property.

In addition, when producing a pair of cyclonic air flow in single space, compare with produce single cyclonic air flow in single space, whirlwind can form lessly.

Herein, even cyclone separator 110 formation is less, the centrifugal force that produces at inlet 120 places is also big than of the prior art, has therefore improved the dust separation performance.

In addition, when in single space, producing a pair of cyclonic air flow, can realize and the dust separation performance of air through the same level of dust separation performance in the structure of a plurality of dust separation unit.Therefore, need not extra dust separation unit is used for dust is separated from the air of discharging from dust separation unit.Yet, also extra dust separation unit can be set in the present embodiment.

And, when one of every side in cyclone separator 110 ground produces a pair of cyclonic air flow and cyclonic air flow towards central flows, strengthen at the cyclonic air flow of centre.Therefore, be better than the cyclonic air flow that on two inlet 120 sides, produces at the cyclonic air flow that the centre of cyclone separator 110 produces.

Therefore, when this to cyclonic air flow when the centre of cyclone separator 110 is converged, compare with the situation that in single space, produces single cyclonic air flow, the intensity of air-flow is bigger, thereby has improved the dust separation performance.

The dust that moves to cyclone separator 110 central authorities can be discharged to dust receptacle 20 through dust export 130 by strong cyclonic air flow, therefore can improve the dust emissions performance.

Hair and other impurity are because static can be easy to be attached to the import or the inboard of dust export 130.But, because in the present embodiment, produce very strong cyclonic air flow at dust export 130 places, so hair and other impurity can not be attached to dust export 130, and can easily be discharged to dust receptacle 20.

Outlet 116 forms and runs through each sidepiece 115, to discharge the air that dust separation fallen in cyclone separator 110.

In addition, each exports 116 couplings and is associated with filter member 150, to filter the air of discharging.At length, filter member 150 is constructed with cylindric securing member 152 that is anchored on cyclone separator 110 inboards and the coniform filter 154 that extends in order to filtered air from securing member 152.In addition, being formed with a plurality of eyelets 156 in filter 154 passes for air.

Therefore, the air that separates dust in cyclone separator 110 passes described a plurality of eyelet 156, then through exporting 116 from cyclone separator 110 discharges.

, be not formed with through hole in the securing member 152 herein, therefore can be discharged from immediately through import 120 inhaled airs, but can circulation reposefully in cyclone separator 110.

That is to say that by securing member 152, the circulation of bootable inhaled air to be producing cyclonic air flow stably in cyclone separator 110, thereby improves the dust separation performance.

Be arranged on length (L1) between a pair of filter member 150 in the cyclone separator and can be made into width (L2) greater than dust export 130.

At length, the cyclonic air flow that produces in cyclone separator 110 converges in the central authorities of cyclone separator 110 as mentioned above, and discharges through dust export 130 by the dust that cyclonic air flow is separated from air.

At this, when this makes width (L2) less than dust export 130 to the length between the filter member 150 (L1), just can not discharge such as the impurity of hair and thin paper, but can be attached to filter member 150 or accumulate in eyelet 156 inboards from dust export 130.In this case, air is not easy to pass filter member 150, thereby causes suction to reduce.

Therefore, in the present embodiment, this makes width (L2) greater than dust export 130 to the length between the filter member 150 (L1), makes and can discharge fully through dust export 130 such as the impurity of hair and thin paper.

As above describe in the present embodiment, air is drawn in the cyclone separator 110 through a plurality of inlets 120, separated the air of dust and then discharge from cyclone separator 110 through a plurality of outlets 116 in cyclone separator 110.

Therefore, discharge through each outlet 116, be easy to discharge to allow air through the air that each inlet 120 is drawn in the cyclone separator 110.

When therefore air was easy to from cyclone separator 110 discharges, in fact suction increased, and cyclonic air flow carries out in cyclone separator 110 reposefully.

In addition, even when dust accumulation makes that on such filter member air can not easily flow, air can be discharged via other filter member, prevents the unexpected loss of air suction thus.

On the body 111 of cyclone separator 110, be formed with opening 112, to allow the replacing of filter member 150.Opening 112 opens and closes by covering member 160.Be provided with containment member 114 in opening 112 and the coupling connection location of covering member 160.

Herein, the inner surface of lid member 160 can form when covering member 160 and be coupled to body 111 the identical curvature that has in interior week with body 111.That is to say the continuous surface of interior week formation of the interior week of lid member 160 and body 111.Therefore, can prevent in the cyclone separator 110 because the variation of the cyclonic air flow that lid member 160 causes, and can keep cyclonic air flow equably.

In addition, because lid member 160 is coupled to cyclone separator 110 removably, so can pulling down, the user covers member 160, with inboard and the filter member 150 of easily changing filter member 150 and easily clearing up cyclone separator 110.

In dust receptacle 20, be limited with the dust chamber 23 that is used to store dust, and in the top of dust receptacle 20, be limited with dust inlet 21.In addition, dust inlet 21 is provided with the containment member 24 that is used to seal the contact area between dust inlet 21 and the dust export 130.Herein, containment member 24 also can be arranged on the dust export 130.

Below, will the operation of dust-separating apparatus be described.

Fig. 6 and Fig. 7 are the cutaway views that illustrates according to the air-flow in the dust-separating apparatus of first embodiment, and wherein, Fig. 6 is the cutaway view that air-flow is shown that Fig. 1 is got along the A-A line, and Fig. 7 is the cutaway view that air-flow is shown that Fig. 1 is got along the B-B line.

Referring to Fig. 6 and Fig. 7, when vacuum cleaner produced suction, the air that comprises dust flowed along suction guide apparatus 30.Flow to allocation units 40 by suction guide apparatus 30 flow air, and be assigned to each inlet 120 by allocation units 40.Then, the air that comprises dust passes each inlet 120 and tangentially is inhaled in the both sides of cyclone separator 110.

Converging in the centre of cyclone separator 110, and in this process, air is subjected to different centrifugal force with dust because of the different of their weight to inhaled air, so separate between them along the rotation of the inner surface of cyclone separator 110.

The dust of separating (with dashed lines representative) is discharged through dust export 130 from the central authorities of cyclone separator 110, and the dust of discharging flows through dust export 130 and flow in the dust receptacle 20.

In contrast, filter by filter member 150, pass outlet 116 then and discharge from cyclone separator 110 with dust separating air (representing) with solid line.The air of discharging flows through corresponding air outlet slit 140, converges converging path 142 places, and enters the main body of vacuum cleaner.

Fig. 8 is the stereogram according to the dust-separating apparatus of second embodiment of the invention.

Except that the structure of the air flue that is positioned at dust separation unit, present embodiment is all identical in all others with first embodiment.Therefore, with the description that only provides the characteristic of present embodiment.

Referring to Fig. 8, comprise dust separation unit 210 and dust receptacle 270 according to the dust-separating apparatus of present embodiment, dust receptacle 270 is arranged on the outside of dust separation unit 210 to be stored in isolated dust in the dust separation unit 210.

Dust separation unit 210 comprises the cyclone separator 220 that is used to produce cyclonic air flow.The diameter of the centre of cyclone separator 220 forms the diameter greater than every side of cyclone separator 220.Centre at cyclone separator 220 is formed with dust export 250, will isolated dust emissions arriving dust receptacle 270 in cyclone separator 220.

Fig. 9 is the cutaway view that Fig. 8 is got along the C-C line, and Figure 10 is the cutaway view that Fig. 8 is got along the D-D line, and Figure 11 is the cutaway view that Fig. 8 is got along the E-E line.

Referring to Fig. 9 to Figure 11, ground of a pair of air intake 221 every sides is formed on every side of cyclone separator 220.Therefore, when air when each air intake 221 sucks, the corresponding a pair of cyclonic air flow of generation cyclone separator 220 in.This that results from cyclone separator 220 both sides converges in central authorities cyclonic air flow, and isolated dust also converges and is disposed to dust receptacle 270 through dust export 250 in central authorities.

Therefore, the inner space of cyclone separator 220 can be divided into: be positioned at the dust separation zone 222 of both sides, dust is separated by cyclonic air flow in dust separation zone 222; And being formed on dust export zone 224 between the dust separation zone 222, dust converges and discharges in dust export zone 224.That is to say that dust separation zone 222 is formed on every side in dust export zone 224.In addition, the value of the vertical section area in dust export zone 224 is greater than the value of the vertical section area in dust separation zone 222.

The inside of dust export 250 comprises path guiding device 260, and this path guiding device 260 directed flow to air of dust receptacle 270 in the dust emissions process enters cyclone separator 220.

That is to say that path guiding device 260 is separated the inner space of dust export 250, thereby in dust export 250, form dust export path 252 and air current return circuit 254.

At length, path guiding device 260 comprises: vertical first guide portion 262 that forms; Second guide portion 264 of extending towards dust export zone 224 from the top of first guide portion 262 with predetermined curvature; And the 3rd guide portion 266 of extending from the bottom water level land of first guide portion 262.

In more detail, first guide portion 262 is used for the inner space of dust export 250 is divided into two paths, i.e. dust export path 252 and air current return circuit 254.

Second guide portion 264 forms to be had and the corresponding curvature of the curvature in dust export zone 224.Therefore, second guide portion 264 is used for keeping the cyclonic air flow in dust export zone 224.

In addition, second guide portion 264 allows easily to mix with cyclonic air flow in the dust export zone 224 via the air that air current return circuit 254 refluxes by dust export zone 224.

Be formed with opening 267 in the 3rd guide portion 266, pass through and permission filtration dust to allow the air in the dust receptacle 270.That is to say,, prevent that the dust in the dust receptacle 270 from flowing in the dust export zone 224 through air current return circuit 254 by opening 267.Therefore, the 3rd guide portion 266 is as the filter element of filtered air.

As mentioned above, because the air in the dust receptacle 270 returns cyclone separator 220 through air current return circuit 254, so prevented to be attached to the inboard of dust export path 252 and then to cause suction to reduce, and air-flow is not interrupted to keep the consistent level of suction such as big impurity such as thin papers.

Particularly, if dust blocks dust export path 252, so isolated dust can't be discharged into dust receptacle 270, and therefore isolated dust is deposited in the dust separation unit 10, flows so the dust of being retained hinders air.

But, when further being formed with the air current return circuit 254 that is communicated with dust receptacle 270 and cyclone separator 220, the vacuum pressure that is produced by the vacuum motor that is arranged in the vacuum cleaner main body acts on the air current return circuit 254 constantly, and this vacuum pressure allows the dust emissions in the dust export path 252 to arrive dust receptacle, therefore can keep air-flow equably.In addition, when air-flow is kept equably, prevent reducing of suction, and can keep suction equably.

Below, will provide description according to the operation of the dust-separating apparatus of present embodiment.

The air that comprises dust passes through described a pair of inlet 221, and is inhaled in the cyclone separator 220 along the tangential direction of cyclone separator 220.

Inhaled air converges in dust separation zone 222 circulations that are arranged in both sides and at 224 places, dust export zone, and in this process, because the centrifugal force that the varying in weight of air and dust causes them to be subjected to is also different, air and dust are owing to different centrifugal force is separated.

Isolated dust (being illustrated by the broken lines) circulates in dust export zone 224 and discharges along the tangential direction of dust export path 252, and the dust of discharge flows through dust export passage 252 goes forward side by side into dust container 270.Herein, be not only dust, but also some air is also discharged through dust export path 252.

On the contrary, the air (being represented by solid line) that separated dust is filtered by filter element 230, then by exporting 229 to discharge from cyclone separator 220.The air of discharging flows through air outlet slit 240.

The air that enters dust receptacle 270 is by opening 267 and flow to air current return circuit 254 being back to dust export zone 224, and mixes with cyclonic air flow in dust export zone 224.
