Description
Technical field
The present invention relates to a kind of Wet-dry dust catcher, mainly through arranging the baffle plate of position changeable (band drive unit) for improving the airflow efficiency of Wet-dry dust catcher, being particularly useful for low power Wet-dry clean robot.
Background technology
Existing clean robot mainly refers to intellective dust collector, the intellective dust collector relating to commodity has multiple, and as commodity intelligent floor cleaning machine only visible two kinds at present, see http://www.bblqs.com/article/399.htm, also can not mop floor (washing ground), the clean robot of dust suction unification occurs, the present inventor newly devises a kind of brush, see ZL201210446511.7, make can mop floor (washing ground), the clean robot of dust suction unification occurs becoming possibility, although there is the dust catcher of non intelligent Wet-dry at present, mostly have employed the air-flow that baffle plate hinders carrying liqs, make gas-liquid separation, the efficiency comparison of this structure air-flow is low, so mostly adopt powerful dust sucting motor.For miniaturized, battery-powered small-power intelligent robot, it can be mopped floor and addle is taken away some and undertake to do what is apparently beyond one's ability.Chinese family is preferred to mop floor comparatively speaking, and dust catcher is used fewer, and therefore floor cleaning machine should be more welcome in China.Current with dragging (washing) machine (washing ground dryer) is common in the large area such as market, office place, the floor-cleaning machine that can meet family expenses or crowded place is rarely seen a, for power strange advanced Small Washing ground dryer SC350(copys type not very), need manual operation, power is 450 watts.Because it is more expensive that the relevant parts of robot comprise the relative costs such as controller, sensor, driving mechanism, and for clean robot, dust suction, the control mechanism washing ground, sensor, driver part are substantially identical, if it is the thing of making something perfect even more perfect that a clean robot possesses the function mopped floor with dust suction simultaneously, " possessing the function mopped floor with dust suction " of referring to here simultaneously, refer to that clean robot both can use as automatic cleaner, machine uses with can be used as again automatic washing (dragging), does not refer to that it can deal with dry, wet cleaning environment simultaneously.Because clean robot mostly uses powered battery, the heavy cost of battery weight is high, and a service time is short, and dust sucting motor power used can not be too large, make the cleaning effect that clean robot has had, and needs the service efficiency considering to improve dust sucting motor.
Summary of the invention
Object of the present invention be exactly in order to for dry suction and wash (wet inhale) two kinds of different use occasions take different clean mechanism, in dry, wet two kinds of situations, ensure the service efficiency that air-flow that dust sucting motor drives is high as far as possible.
The present invention is design like this:
Under the impeller base that dust catcher arranges impeller inlet channel, arrange a shelter towards the band drive unit of suction passage, this shelter has three kinds of set-up modes:
The first: shelter is the screen holder for arranging filter screen, and namely the related filter screen of screen holder is movable.
When screen holder driven device moves into, impeller inlet channel is covered by screen holder, enters dust suction mode of operation; When screen holder driven device shifts out, impeller inlet channel opens wide, and enters the mode of operation that mops floor.
When washing ground, screen holder driven device moves on on one side, impeller inlet channel opens wide, be mingled with the air-flow of water droplet after entering suction passage, the impeller of dust sucting motor driving is directly entered by impeller inlet channel, the formula impeller of being centrifuged spills the sewage collecting tank to impeller periphery, and heavier liquid is left on sewage collecting tank, and air-flow is then by outside airflow emissions channel discharge machine.
When dust suction, screen holder driven device moves and covers impeller inlet channel, after air-flow enters suction passage, stays in dustbin through rubbish during filter screen on screen holder, comparatively clean gas enters impeller inlet channel, by the impeller that dust sucting motor drives, then by outside airflow emissions channel discharge machine, consistent with the air-flow method of operation of standard vacuum, be not subject to extra stop, but when washing ground mode and working, owing to not passing through filter screen, airflow efficiency significantly improves.
The barrel strainer frame that filter screen is set is there is between the suction passage and impeller inlet channel of Wet-dry dust catcher, window is had at the bottom of screen holder bucket, one is arranged towards suction passage bottom screen holder, cross section is the baffle plate of fairshaped band drive unit, when baffle plate driven device moves into, at the bottom of screen holder bucket, window is blocked by baffle plate; When baffle plate driven device shifts out, window at the bottom of screen holder bucket opens wide.
During dry suction, air-flow is diverted to around the filter screen after baffle plate by baffle plate, is stayed by rubbish in dustbin, and air-flow enters impeller through filter screen and discharges outside machine; During wet suction, baffle plate driven device is removed, and screen holder bottom windows is opened wide, and air-flow directly enters in screen holder, and obstructed screen pack enters impeller, spills the sewage collecting tank to impeller periphery, and the air-flow of separation is directly discharged outside machine, and water droplet is stayed in sewage collecting tank.
Consistent with the air-flow method of operation of standard vacuum during dust suction mode, be not subject to extra stop, but when washing ground mode and working, owing to not passing through filter screen, airflow efficiency significantly improves.
Drive unit can be one in bull stick, push rod, driving lever, stay cord.
The second: shelter be arranged on dust catcher screen holder bottom, cross section is the baffle plate of fairshaped band drive unit.
The barrel strainer frame that filter screen is set is there is between the suction passage of dust catcher and impeller inlet channel, window is had at the bottom of screen holder bucket, one is arranged towards suction passage bottom screen holder, cross section is the baffle plate of fairshaped band drive unit, so-called cross section is streamlined finger stop plate towards less streamlined of the windages such as the tapered curve in suction passage direction, is a taper fairing under such as baffle plate.When baffle plate driven device moves into, at the bottom of screen holder bucket, window is blocked by baffle plate, enters dust suction mode of operation; When baffle plate driven device shifts out, window at the bottom of screen holder bucket opens wide, and enters water suction mode of operation.
When washing ground, baffle plate driven device moves on on one side, screen holder is not blocked by baffle plate, be mingled with the air-flow of water droplet after entering suction passage, through screen holder bottom windows, the impeller directly being entered dust sucting motor driving by impeller inlet channel, the formula impeller of being centrifuged spills the sewage collecting tank to impeller periphery, and heavier liquid is left on sewage collecting tank, and air-flow is then by outside airflow emissions channel discharge machine.
When dust suction, baffle plate driven device moves and blocks screen holder bottom windows, after air-flow enters suction passage, be diverted to around filter screen by the taper fairing under baffle plate, dustbin is stayed through rubbish during filter screen, comparatively clean gas enters impeller inlet channel, by the impeller that dust sucting motor drives, again by outside airflow emissions channel discharge machine, consistent with the air-flow method of operation of standard vacuum, be not subject to extra stop, but when washing ground mode and working, owing to not passing through filter screen, airflow efficiency significantly improves.Taper fairing is not necessity, but has the machine windage of radome fairing relatively little.
Drive unit in above-mentioned two kinds of modes can be one (certainly also can use other type of drive) in bull stick or push rod, driving lever, stay cord.
The third: shelter is the baffle plate of the band drive unit be arranged between the suction passage of dust catcher and screen holder 6.
Wash (water suction) time, be mingled with the air-flow of water droplet after entering suction passage, the heavier water droplet of a part is beaten on baffle plate, by in the lower edge instillation dustbin of baffle plate, another part water droplet in air-flow then relies on inertial impaction at garbage box and instills in dustbin, and then through filter screen, (filter screen can be arranged on position at the bottom of the bucket of screen holder to air-flow, also can be arranged on around screen holder, the impeller of dust sucting motor driving is entered, finally outside discharge machine by impeller inlet channel.
When dust suction, baffle plate driven device is removed, and after air-flow enters suction passage, directly to filter screen, entered the impeller of dust sucting motor driving by impeller inlet channel through filter screen, finally outside discharge machine, rubbish is then trapped in dustbin.Because do not have the obstruct of baffle plate, airflow efficiency is higher.
No matter be dry dust suction or wet water suction (washing ground) under the third mode, air-flow all can enter impeller by strainer filtering again, impeller is peripheral without sewage collecting tank, as standard vacuum, drive unit can be one (certainly also can use other type of drive) in bull stick or push rod, driving lever, stay cord.

Embodiment
The impeller base arranging impeller inlet channel 2 at dust catcher arranges a shelter towards the band drive unit of suction passage 1 for 28 times, and this shelter has three kinds of set-up modes:
The first: shelter is the screen holder 6 for arranging filter screen 5, and namely the related filter screen of screen holder 65 is movable.
When screen holder 6 driven device moves into, impeller inlet channel 2 is covered by screen holder 6, enters dust suction mode of operation; When screen holder 6 driven device shifts out, impeller inlet channel 2 opens wide, and enters the mode of operation that mops floor.
As Fig. 1 (a) with washing (dragging) time, screen holder 6 driven device moves on on one side, impeller inlet channel 2 opens wide, be mingled with the air-flow of water droplet after entering suction passage 1, the impeller 9 of dust sucting motor driving is directly entered by impeller inlet channel 2, be centrifuged formula impeller 9 and spill sewage collecting tank 10 to impeller 9 periphery, heavier liquid is left on sewage collecting tank 10, and air-flow is then discharged outside machine by airflow emissions channel 12.What is called is washed (dragging) refers to dust catcher also with automatic water jetting (cleaning fluid) device, mainly comprise filtered water tank 18, water pump 19, outlet conduit and delivery port 20, and Wet-dry dust catcher is general without water injector, can be used for blotting the water stain of ground, no matter all applicable with or without automatic sprinkler the present invention is.
When dust suction as Fig. 1 (b), screen holder 6 driven device moves and covers impeller inlet channel 2, after air-flow enters suction passage, 21 are stayed in dustbin through rubbish during filter screen 5 on screen holder 6, comparatively clean gas enters impeller inlet channel 2, the impeller 9 driven by dust sucting motor, discharge outside machine by airflow emissions channel 12 again, consistent with the air-flow method of operation of standard vacuum, be not subject to extra stop, but when washing ground mode and working, owing to not passing through filter screen 5, airflow efficiency significantly improves, and filter screen 5 is also improved greatly by the situation of sewage pollution.
If the impeller inlet channel 2 of dust catcher is vertically downward towards suction passage 1, as Fig. 1, the rubbish be adsorbed on when stopping operating to prevent impeller under filter screen 5 directly drops out suction passage, cause secondary pollution, one radome fairing 8 can be set at screen holder for 6 times, less streamlined of the windages such as the tapered curve in cross section of radome fairing 8, taper fairing 8 is not necessity, but has the machine windage of radome fairing 8 relatively little.
After permanent use, screen holder 6 due to drive unit wearing and tearing or fatigability distortion cause sagging, the sealing property of itself and impeller base 28 lower edge is deteriorated, driving shaft can be allowed more to turn over a bit, or move past a bit more, to ensure better sealing.The transfer framework 13 of Path Properties can be set for 28 times at impeller base, as Fig. 2, screen holder 6 can be arranged the baffle plate handle 43 of applicable transfer framework 13, baffle plate handle 43 can be arranged on the roller or bearing that rotate in transfer framework, transfer framework 13 two ends can arrange postive stop baffle 42(that defining baffle handle 43 shifts one's position, and to shift one's position forward and backward be comparatively speaking, also can by behind two positions on the contrary conversion, before conversion, for the purpose of attractive in appearance, before screen holder 6 position in dust suction mode is defined as conversion, washes ground working method and be defined as conversion afterwards).In order to ensure sealing better, spring leaf or the rubber blanket of some resilient projections also can be set at transfer framework 13 inner face.Transfer framework 13 may also be the groove 44 caving in and be arranged on impeller base 28, and one end of baffle plate handle 43 or screen holder 6 is embedded in groove 44 by suspension arrangement 45, and can slide in groove 44, as Fig. 5.
Drive unit can be one (certainly also can use other type of drive) in bull stick 3, push rod 3-2, driving lever 3-3, stay cord 3-4.Can be manually, also can be electronic.Be exactly manually by bull stick 3, push rod 3-2, driving lever 3-3, stay cord 3-4 drive unit directly or conversion (as by bevel gear) curve or extend to the top of machine or bottom or (shell) around, come back rotation or promotion with hand or stir; Electronic is exactly driven by the driving shaft that motor (can acceleration and deceleration mechanism) exports.Such as drive leading screw by motor, push rod moves in the mode of nut, or motor and push rod drive in the mode of gear, tooth bar; Motor the rotating shaft of Direct driver driving lever or motor can stir driving lever by driving cam, these belong to mechanically conventional with electric machine rotation conversion in back and forth or the mode of rectilinear motion do not enumerate.
Screen holder 6 is connected with a bull stick 3, and bull stick 3 rotates front impeller inlet channel 2 and opens wide, and towards suction passage 1, bull stick 3 rotates the related filter screen 5 of rear screen holder 6 and covers impeller inlet channel 2, and bull stick 3 can as following three kinds of forms:
(1) bull stick 3 is downward through impeller base 28, as Fig. 1 (a, b).
Bull stick 3 drive unit is made up of motor, reducing gear, driving shaft, screw rod, motor via reducer structure drives driving shaft, driving shaft is driven through screw thread in the mode that eye cutting enters (or other similar screwdriver contacts with screw) and is spun on impeller inlet channel 2 Its lower side, and the other end of screw rod is set together with screen holder 6 (being connected as by key).Allow bull stick 3 be elevated in hold-down nut mode rotate, during rising, screen holder 6 blocks impeller inlet channel 2, decline simultaneously, screen holder 6 turns over an angle, open wide impeller inlet channel 2, the benefit of this type of drive is that screen holder 6 can tighten up space between impeller inlet channel 2 base (impeller inlet channel 2 base also can tilt away from one end of bull stick or screen holder 6 can tilt away from one end of bull stick) slightly downward slightly upward.
If there is transfer framework 13 below impeller passage 2, bull stick can not exist in the mode of screw rod (not needing to be elevated among a small circle), it is exactly a turning cylinder be fixed together with screen holder 6 (driving shaft as flat in axle head milling), bull stick 3 rotates front impeller inlet channel 2 and opens wide, towards suction passage 1, bull stick 3 rotates rear screen holder 6 and covers impeller inlet channel 2.
(2) bull stick 3 be placed in screen holder 6 extension rod on, as this mode (a, b), also can be thought the driving lever (middle bull stick place is turning cylinder) stirred extension rod outer end by Fig. 3.
(3) bull stick 3 is parallel to place plane bottom impeller base 28, and as Fig. 3, (c, d) drives screen holder 6 to rotate in the mode of " renovating ".
Screen holder 6 is connected with a push rod 3-2, and before push rod 3-2 promotes, impeller inlet channel 2 opens wide, and towards suction passage 1, after push rod 3-2 promotes, the related filter screen 5 of screen holder 6 blocks impeller inlet channel 2, as Fig. 4 (a, b).
Screen holder 6 is connected with a driving lever 3-3, and driving lever 3-3 stirs front impeller inlet channel 2 and opens wide, and towards suction passage 1, driving lever 3-3 stirs the related filter screen 5 of rear screen holder 6 and blocks impeller inlet channel 2, as Fig. 4 (c, d).
Screen holder 6 is connected with a stay cord 3-4, and stay cord 3-4 pulls front impeller inlet channel 2 to open wide, and towards suction passage 1, stay cord 3-4 pulls the related filter screen 5 of rear screen holder 6 to block impeller inlet channel 2, as Fig. 5 (a, b).Stay cord generally uses steel wire rope, with stainless steel making or through antirust treatment, also can by the nylon yarn rope or belt of the not easy fracture through preservative treatment (such as going up cured), and be compact conformation by the benefit of stay cord, shortcoming is that parts are more.There is the groove for limiting stay cord the periphery of screen holder 6, skid at screen holder 6 or driving shaft periphery to prevent rope, can being fixed on rope on screen holder 6 or driving shaft (or wheel) partially over the mode such as embedding or fasten, in order to control the angle of movement, generally also need to arrange a driven axle (wheel).
Said structure (such as impeller base 28 times) is for the horizontally disposed dust catcher of impeller 9, structure of the present invention also can be turned through certain angle and uses, if Fig. 7 (a) is exactly the Wet-dry structure of dust collector schematic diagram that impeller 9 is vertically arranged, horizontally disposed relative to impeller 9, vertically arrange and complete machine structure can be allowed shorter, but suction passage 1 needs to curve, and to a certain degree reduces the efficiency of air-flow.The difference to some extent of the sewage collecting tank 11 that the Wet-dry dust catcher that impeller 9 is vertically arranged is used and horizontally set, as Fig. 7 (b), also can as zl201410308576.4(wall cleaning device) describe in description, under this setup, window can be set in dust catcher side, dump rubbish when opening, or take out the water tank of drawer type.
The second: shelter be arranged on dust catcher screen holder 6 bottom, cross section is the baffle plate 4 of fairshaped band drive unit.
Namely there is the barrel strainer frame 6 that filter screen 5 is set between the suction passage 1 of dust catcher and impeller inlet channel 2, window 7 is had at the bottom of screen holder 6 barrels, one is arranged towards suction passage 1 bottom screen holder 6, cross section is the baffle plate 4 of fairshaped band drive unit, so-called cross section is streamlined finger stop plate 4 towards less streamlined of the windages such as the tapered curve in suction passage direction, and such as baffle plate is for 4 times a taper fairing 8.When baffle plate 4 driven device moves into, at the bottom of screen holder 6 barrels, window 7 is blocked by baffle plate, enters dust suction mode of operation; When baffle plate 4 driven device shifts out, at the bottom of screen holder 6 barrels, window 7 opens wide, and enters water suction mode of operation.
When washing ground as Fig. 8 (a), baffle plate 4 driven device moves on on one side, screen holder 6 is not blocked by baffle plate 4, be mingled with the air-flow of water droplet after entering suction passage 1, through screen holder bottom windows, the impeller 9 directly being entered dust sucting motor driving by impeller inlet channel 2, be centrifuged formula impeller 9 and spill sewage collecting tank 10 to impeller 9 periphery, heavier liquid is left on sewage collecting tank 10, and air-flow is then discharged outside machine by airflow emissions channel 12.
