Description
Technical field
the present invention relates to a kind of vacuum cleaner.
?
Background technology
On the dustless bag of
the known cyclone type dust catcher, the cyclonic filter system has two kinds substantially.First kind of built-in extra screen pack in the cyclone dust bucket as first order filtration system normally filters dust like the HEPA filter.The characteristics of this system are a large amount of first-hand dusts along with air-flow directly rotates around the HEPA filter after getting into the dirt bucket; Because first order cyclonic separation weak effect often, dust can not separatedly effectively go out and be brought under control, and screws off but in the cyclone dust bucket, constantly screw on air-flow; Be easy at last to be seen through the HEPA filter the suction of central suction power and attached on the HEPA filter; And the filtration grade of HEPA filter is very high, and screen pack is easy to stopped up by dust, thereby makes the suction power of dust catcher descend very soon; Cause the user to have to often clean or change filter, influenced the normal use of dust catcher.Therefore, this kind dust catcher is just constantly substituted by second kind of multi-stage spiral-flow-wind dust sucking device.
second kind are usually alleged multi-stage spiral-flow-wind dust sucking devices, and it carries out the multistage cyclone separation through the cyclonic separation unit that plural serial stage is set to dust, thereby makes dust can be stayed up hill and dale in the separative element of dust catcher.DYSON (wearing gloomy/Britain) as the rotoclone collector leader has promptly adopted above-mentioned design at present.Yet find that in actual use perhaps owing to the limitation of domestic vacuum cleaners size dimension and the problem of structural design, first order cyclone filter often can not centrifugalize dust efficiently and control dust effectively.This mainly is because as cyclone filter, its operation principle is exactly to utilize centrifugal principle that heavier-than-air particle is separated from air in the rotation at a high speed.Reach this purpose, two main points are arranged: the one, rotate at a high speed, promptly dust will rotate at a high speed with air-flow, and dust granule increases from the attraction center more and more far away with speed like this.The 2nd, particle is enough far away from the suction force center, and particle just can be fled to such an extent that go out.If just speed is fast, but can not arrive enough far point, that is to say that particle is far away inadequately from the suction force center, it still can only rotate at a high speed with air-flow.Like this, the cyclonic separation dirt bucket of domestic vacuum cleaners, according to centrifugal separating effect, diameter is the bigger the better, and highly also is high more good more.But receive the restriction of dust catcher complete machine size, diameter can not be very big, and diameter is big, and rotary speed can reduce, centrifugal effect meeting variation, so diameter can not be very big, that is merely able to increase the height that vacuum cleaner cyclone separates the dirt bucket.On dust catcher; The aspirating mechanism operated by rotary motion is above dust catcher; The height of cyclonic separation dirt bucket is high more, and just long more below the dirt bucket, separating effect is just good more like this; If there are not enough length spaces to let dust granule arrive the critical point of an escape below, dust just cannot leave the air-flow of rotation.Around the dirt bucket is a barrel wall, and dust cannot be escaped, and near the suction center, is the air-flow that rotates at a high speed, and dust cannot separate.Dust-contained airflow must be to going down, and must be to rotate downwards at a high speed, and the particle of Different Weight could escape from swirling eddy in the critical point different from the suction force center.
so, reason is recognized to go up and said that whirlwind speed is big more, and is long more below the dirt bucket, dust granule separate with regard to more totally, thorough more.And actual situation is, the speed that the dust catcher air-flow gets into is very big, and dirt bucket lower length cannot be very long, the air-flow that rotates at a high speed abrim in the dirt bucket, and the air-flow of rotation can drive the dust that becomes quiet at any time once more at a high speed, and promptly dust cannot stop.Particularly light, book; Often constantly rotate such as the modal dust of present family such as the scraps of paper, fibre fluff, hair with air-flow; On the screen pack attached to the setting of next stage cyclone filter front, cause dust catcher suction to descend at last, or get into the next stage filtration system; Thereby increase the weight of the burden of next stage filtration system, also therefore cause this multistage cyclone system effectively and efficiently dust as much as possible not to be filtered out.For example publication number is the Chinese patent " multi cyclone dust-separating apparatus of vacuum cleaner " of CN101292851; Wherein disclosed just as above-mentioned mention can not effectively carry out dust separating dust catcher; After falling into the bottom of this grade cyclone separator through first order cyclone separator separated dust, having the sub-fraction dust can not block owing to having, and along with ascending air is carried secretly to the mesh filter place; This not only can cause the separative efficiency of first order cyclone separator to lower; And because the grit of the dust of being carried secretly is generally bigger, and the mesh of mesh filter can be blocked, thus whole dust catcher cisco unity malfunction made.Other is also to be to have as above problem in the rotoclone collector described in CN1422187A, the CN100998484A like publication number.

The specific embodiment
are come technical scheme of the present invention is done further to set forth below in conjunction with accompanying drawing and concrete embodiment.
are referring to shown in Fig. 1-3; A kind of vacuum cleaner comprises mechanical type separator 1, and this mechanical type separator 1 comprises the separation dust collector bucket 11 with inner chamber of bottom sealing; Offer the dust inlet 12 that is connected with bowl inner chamber on the circumferential side wall of separation dust collector bucket 11; Its top offers first air outlet 110, and dust-contained airflow gets into the inner chamber of separation dust collector bucket 11 from dust inlet 12, after cyclonic separation, flows out from first air outlet 110.Separation dust collector bucket 11 comprises the staving with inner chamber of both ends open and removably is connected the bottom 16 of its bottom that bottom 16 is tightly connected with above-mentioned staving mutually.Be provided with dividing plate 13 in the inner chamber of separation dust collector bucket 11; Dividing plate 13 is positioned at the below of dust inlet 12; Dividing plate 13 is separated into upper chamber and lower chambers two parts with the inner chamber of this separation dust collector bucket 11; The part that wherein forms between the bottom of separation dust collector bucket 11 and the dividing plate 13 is a lower chambers, that is the part between bottom 16 and the dividing plate 13 is lower chambers, the dust storage chamber of this lower chambers that is this mechanical type separator 1.The taper surface of the upper surface of dividing plate 13 for dispersing downwards offers a plurality of through holes 14 on the dividing plate 13, upper chamber is connected through through hole 14 with lower chambers.Here, through hole 14 has two, and the inwall that these two through holes 14 are positioned at dividing plate 13 and separation dust collector bucket 11 is the junction mutually.In lower chambers, also be provided with a plurality of catch 15, these a plurality of catch 15 can be arranged on the circumferential side wall of separation dust collector bucket 11, also can be arranged on the upper surface of bottom 16.Like this, dust-contained airflow earlier in the rotation of the top of separation dust collector bucket 11, flows in the lower chambers from a through hole 14 when it is threaded to dividing plate 13 places after dust inlet 12 gets in separation dust collector bucket 11 inner chambers again.Dust-contained airflow gets in the lower chambers and in lower chambers, continues to be rotated down, rapid stall when it touches catch 15, and the dust in the dust-contained airflow then falls down rapidly because of fierce collision stall, and drops down onto the bottom of lower chambers.Because dividing plate 13 has separated the central suction power that first air outlet 110 is had on the separation dust collector bucket 11; Just lost central suction power after the lower chambers of dust-contained airflow entering dividing plate 13 bottoms; Collide with catch 15 again, the kinetic energy that this dust-contained airflow has also lost rotation or waved, thereby in lower chambers, quiet down rapidly; Dust in the air-flow also falls into the bottom of lower chambers rapidly because of reasons such as collision stall and self gravitations, and is not easy to be driven again.Like this, dust-contained airflow has promptly carried out mechanical separation in this mechanical type separator 1, and the dust that quality is bigger is separated, and isolated dust is also got up by control in this lower chambers.Because the space is limited in the lower chambers, the air-flow that gets into lower chambers can oppositely upwards flow, and the dust-contained airflow after mechanical type separates is aspirated back the epicoele of separation dust collector bucket 11 from another through hole 14.
are referring to shown in Fig. 1-3; In the present embodiment; The provided upstream that is positioned at first air outlet 110 in the inner chamber of separation dust collector bucket 11 is equipped with mesh filter 17; This mesh filter 17 is cylindrical, and this mesh filter 17 and the 11 coaxial settings of separation dust collector bucket, and dust-contained airflow carries out filtering again from first air outlet, 110 outflow mechanical type separators 1 through mesh filter 17 after mechanical type separates in the inner chamber of separation dust collector bucket 11.Be permanently connected on the lateral wall of mesh filter 17 and be provided with first guiding rib 18; First guiding rib 18 along mesh filter 17 extend axially and along the circumferential bending of mesh filter 17; This first guiding rib 18 is fitted with the inwall of separation dust collector bucket 11; And the inboard of the dust inlet 12 and first guiding rib 18 is oppositely arranged; Be the inboard that dust inlet 12 should be arranged on the limit portion of first guiding rib, 18 bendings formation, the inner chamber of separation dust collector bucket 11 has just been separated at dust inlet 12 places like this, and an end that when dust inlet 12 gets into separation dust collector buckets 11 inner chambers, is merely able to never blocked when dust-contained airflow gets into; In separation dust collector bucket 11, rotate again, avoided disperseing everywhere in the chamber within it behind the dust-contained airflow entering separation dust collector bucket 11 around a direction.On the lateral wall of mesh filter 17, also be permanently connected and be provided with second guiding rib 19; This second guiding rib 19 is arranged on the outside of first guiding rib 18 obliquely; The direction that second guiding rib 19 tilts is consistent with the rotation direction that is got into dust-contained airflow in separation dust collector bucket 11 inner chambers by dust inlet 12; Second guiding rib 19 is 45 °～60 ° along the angle of the axioversion of mesh filter 17, and after being provided with like this, dust-contained airflow rotates by a direction in the inner chamber of separation dust collector bucket 11; When it rotates to second guiding rib, 19 places; Dust-contained airflow is advanced downwards along the direction that second guiding rib 19 tilts gradually, so just arrives the upper surface of dividing plate 13 apace and gets into lower chambers from through hole 14, makes the dust separation efficient of mechanical type separator 1 improve.
are referring to shown in Fig. 1-3; In the present embodiment; This vacuum cleaner also comprises the Cyclonic separating apparatus 2 that is positioned at mechanical type separator 1 downstream; This Cyclonic separating apparatus 2 comprises one or more whirlwind buckets 21 that are arranged side by side mutually, whirlwind bucket 21 and separation dust collector bucket 11 airflow connection setting mutually.Be provided with 5 here; The axial line of these 5 whirlwind buckets 21 is parallel to each other; Also be provided with between the downstream of the upper reaches of whirlwind bucket 21 and first air outlet 110 one with separation dust collector bucket 11, the whirlwind bucket 21 air intake distributor 22 of airflow connection mutually; This air intake distributor can be divided into multiply with the dust-contained airflow that flows to the Cyclonic separating apparatus 2 from first air outlet 110, and its number of share of stock is identical with the number of whirlwind bucket 21.Also be provided with the core bucket 23 that can be connected with lower chambers in the bottom of Cyclonic separating apparatus 2; The upper and lower end parts of core bucket 23 respectively with the setting that is tightly connected mutually of the bottom of the bottom of Cyclonic separating apparatus 1, separation dust collector bucket 11; Like this; After the cyclonic separation, dust falls into the bottom through this core bucket 23 to dust-contained airflow in whirlwind bucket 21, and the bottom of core bucket 23 is the dust storage chamber of Cyclonic separating apparatus 2.
Below the concrete course of work of the vacuum cleaner of present embodiment down of setting forth:
dust-contained airflow from dust inlet 12 get into the inner chamber of separation dust collector buckets 11 and the inner chamber of separation dust collector bucket 11 with specific direction rotation; And under the guiding of second guiding rib 19, marching to the upper surface of dividing plate 13 apace downwards, this dust-contained airflow gets into the lower chambers along the upper surface rotation of dividing plate 13 and from a through hole 14.When design, should make dividing plate 13 less with the distance of dust inlet 12; Thereby make the dust-contained airflow that gets in separation dust collector bucket 11 inner chambers can arrive dividing plate 13 apace; Thereby get in the lower chambers through through hole 14 apace; Stay to avoid air-flow in upper chamber, to rotate, finally cause the not enough pick-up performance that influences dust catcher of dust catcher integral suction power thereby avoid it to be increased the weight of its burden to Cyclonic separating apparatus by the suction of central suction power.Therefore; Dust-contained airflow does not often carry out any dirt gas separation and has just got in the lower chambers in upper chamber; Dust-contained airflow gets in the lower chambers and moves downwards according to inertia, when it runs into catch 15, with catch 15 fierce collision takes place, and the rapid stall in the collision of fierceness of the dust in the dust-contained airflow hangs down; Fall bottom in lower chambers; And air-flow has been also because dividing plate 13 has cut off the central suction power at separation dust collector bucket epicoele center, and this air-flow is taking place also to have lost the inertia revolving force after the fierce collision with catch 15, thereby no longer rotation and in lower chambers, keep comparatively quietly flow regime in lower chambers; Thereby can not drive the dust rotation bottom the lower chambers, after hanging down, can undisturbedly stay dust the bottom of lower chambers.Because the space of lower chambers is limited; Said flow also can little by little get into upper chamber from another through hole 14; If the dust that has few part to be carried secretly is got back to upper chamber; After then filtering by mesh filter 17; Carry out cyclonic separation once more from first air outlet 110 through a plurality of whirlwind buckets 21 that air intake distributor 22 is divided into multiply air flow direction Cyclonic separating apparatus 2 again, separated dust falls into the bottom of core bucket 23, can compile at the top of whirlwind bucket 21 and from the air outlet that the top cover of dust catcher is offered, discharge through the pure air after whirlwind bucket 21 cyclonic separation.
