Description

The method on the combination of cleaning wiping cloth and cleaner suction nozzle and wet-cleaning floor

Technical field

The present invention at first relates to the combination of a kind of cleaner suction nozzle and cleaning wiping cloth, and wherein, cleaner suction nozzle has a suction inlet.

Background technology

Cleaner suction nozzle is known.It especially is applied in domestic vacuum cleaners for suction process floor, carpet surface or hard floor as attachment device.In addition, it also is known being used for other surface-treated suction nozzle.This suction nozzle is connected with dust catcher by a suction hose or analog usually, so that the higher object of suction position, for example bookshelf surface or similar place.During operation, the zone appearance of the suction inlet of cleaner suction nozzle can keep the negative pressure of cleaning wiping cloth.Correspondingly, the cleaner suction nozzle of batch production can be used for the special hard surface of wiping like this, for example timber floor or slabstone ground.

Summary of the invention

In view of aforesaid prior art, technical problem to be solved by this invention is the combination of constructing with improvement a kind of described type.

This technical problem at first and mainly solves thus, that is, cleaning wiping cloth remains on the suction nozzle by negative pressure, and cleaning wiping cloth is for preventing that sucking liquid has a sealant.Because this structure also can the wet rubbing surface by means of cleaner suction nozzle.Realize the improvement of cleaning effect by wet-cleaning.For avoiding Clean-liquid by for the preferred essential suction air flow of absorption cleaning wiping cloth enters cleaner suction nozzle, and arrive the dust catcher that produces suction airflow via this suction nozzle, described cleaning wiping cloth is equipped with a sealant.The sealing layer plays separate layer.

Below introduce other expansion design feature of the present invention.They both can be used as the preferred addition feature of the above-mentioned technical solution of the present invention, but itself also tool invention be worth.Therefore, in the middle regulation of further developing of theme of the present invention, cleaner suction nozzle has two suction channel branches that separate that are positioned at the cleaning wiping cloth upstream, a sticking negative pressure that is used for the sticking cleaning wiping cloth, and another then is used for the suction of direct floor.This structure so that when operation the suction air flow that produces in the suction nozzle side by separately, be used on the one hand fixedly cleaning wiping cloth, then be used on the other hand the suction of direct floor, wherein, further preferably cover fully when keeping with suction channel branch towards the cleaning wiping cloth in the hole on floor arranging one, attach troops to a unit in keeping cleaning wiping cloth maintenance chamber with suction channel branch to form at least an enclosure space that almost comprises separately negative pressure.Relatively high flowing velocity improves the dynamic pressure in the whole system during by suction operation, then reduces on the contrary static pressure.The wall of less static pressure in flow channel causes suction, and under present case, also just is equivalent to cause suction in the cleaning wiping cloth maintenance chamber of sealing when the absorption cleaning wiping cloth.This produces by a static pressure less than the surrounding air static pressure.Cleaning wiping cloth keeps the negative pressure in the chamber to be preferred for the negative-pressure adsorption of cleaning wiping cloth.The separation of the suction channel branch that passes through to advise has provided uniform negative pressure in each zone of cleaning wiping cloth maintenance chamber.Correspondingly, at identical pressure of the total negative pressure loading surface of cleaning wiping cloth effect.In addition, in sucking with suction channel branch, obtain favourable pumping power by the suction channel branch of separating.Pumping power can be owing to the suction cleaning wiping cloth reduces so that it is adsorbed on the suction nozzle yet.

In preferred design, from vertical direction, Local Phase is folded at least extends with arranging in suction channel branch, therefore, and in the projection of suction channel branch on the suction nozzle bottom or local at least overlapping in the projection on pending floor when moving.In preferred the layout, keep sucking extension below suction channel branch with suction channel branch, wherein, the straight forming cleaning wiping cloth keeps chamber simultaneously in keeping with another design of suction channel branch, and suction for example is the pipeline section shape with suction channel branch, be positioned at maintenance with above the suction channel branch, and at distolateral moulding one nozzle-like suction inlet, this suction inlet further preferably extends past whole suction nozzle transverse to the width of common moving direction.The front area of attaching troops to a unit and preferably being arranged on suction nozzle with respect to the common moving direction of suction nozzle with the suction inlet of suction channel branch in sucking so that suction nozzle is when common direction travels forward, just picks up thicker foul particle before the floor is by the cleaning wiping cloth wiping.

Therefore, stipulate further that suction channel branch at least part is adjacent to extend in the horizontal direction, further extends in the horizontal direction with respect to common moving direction.Therefore, for example be positioned at above the suction nozzle bottom, further with the suction nozzle bottom keep closely spaced, level towards the plane not only keep chamber to intersect with keeping the cleaning wiping cloth with suction channel branch, also and the suction that is arranged on its front at common moving direction intersect with the suction inlet of suction channel branch.

The cleaning wiping cloth zone further preferably is designed for the sealing lip and the floor suction areas that are bearing on the floor by one in the horizontal direction and separates.The sealing lip extends transverse to the common moving direction of suction nozzle in preferred design, further extends past suction nozzle at the whole width of observing transverse to common moving direction.This layout is mainly avoided preferred wetting cleaning wiping cloth because the suction air flow of aspirating through the floor suction areas becomes dry.Because this layout of sealing lip, air suction are limited in being retained on the common moving direction suction nozzle zone of sealing lip front at least, wherein, such sealing lip is set in the side of floor suction areas also preferably further.In addition, through threshold or other flat barrier the time, sealing lip is also as favourable servicing unit.If suction nozzle moves forward in common direction, that is to say, suction areas at first moves on to the top on pending floor, so, the free end zone of sealing lip is located at institute that moving direction tightens cleaning wiping cloth after being connected on attaches troops to a unit on the edge, perhaps covers alternatively the gap that at least one may form between cleaning wiping cloth and suction nozzle bottom surface.Thereby avoided cleaning wiping cloth through threshold or other flat barrier the time, to be torn or to peel off.Sealing lip paves cleaning wiping cloth transiently, and it is cleared the jumps.

In the another kind design, preferably as fixing the replenishing of negative pressure, cleaning wiping cloth remains on the suction nozzle by mechanical device.This machinery fixedly is particularly useful for supporting the negative pressure of cleaning wiping cloth to fix.Therefore, by the placement of mechanical holding device, even in suction airflow for example owing to device is closed when interrupting, cleaning wiping cloth can also continue to be adsorbed on the suction nozzle.In a kind of design, mechanical device is comprised of a magic tape or fastener, and wherein, a fastener is attached troops to a unit in cleaning wiping cloth, and another corresponding fastener is attached troops to a unit in the support component of suction nozzle bottom or cleaning wiping cloth with it.When cleaning wiping cloth was designed to be made of a special textile material, when further for example being made by nonwoven cloth material, this material itself was shaped to the magic tape of ring-type, and at device side one barb-like corresponding magic tape is set.Further alternatively be, mechanical device is buckling and locking device, and this type for example namely, is designed with the kayser latch of elastic construction in case of necessity at device side, its with cleaning wiping cloth in corresponding latch hole acting in conjunction.Strengthen the latch hole edge so that reliably kayser maintenance with the acting in conjunction of kayser latch the time for example can realize by the sealant that is integrated in the cleaning wiping cloth.

To keep with in the suction channel and attach troops to a unit and keep negative pressure in the chamber in the cleaning wiping cloth of cleaning wiping cloth in order increasing, to further develop middle regulation theme of the present invention a kind of, maintenance has occurred the flow channel constriction with suction channel in the upstream of cleaning wiping cloth.This flow channel constriction realized should the zone flow velocity increase, this causes the rising of negative pressure in the cross-sectional expansion zone of cleaning wiping cloth chamber.The flow channel constriction plays Venturi tube-suction nozzle.In another preferably designed, the flow channel constriction designed in the bifurcation region of two flow channel branches, yet, alternatively, also can design the upstream in the cleaning wiping cloth of bifurcated front.

For preventing entering the maintenance channel branch by the foul particle that sucks with the transmission of suction channel branch, stipulate that further the latter further especially separates with suction channel branch with suction by separating element and the suction channel of a filtration members type.The separating device of a filtration members type preferably form is to have the ply of paper of filtering characteristic or the filter element of nonwoven.Separating device also can form by the aperture plate that closely interweaves alternatively.In the another kind design, the separating device of filtration members type can be changed, and preferably is arranged in the bifurcation region of two flow channel branches.

On the common moving direction of suction nozzle, at the entrance that the front and back of cleaning wiping cloth structure one sucks with suction channel branch, this structure is proved to be particularly advantageous.Correspondingly, no matter with before pending floor contacts or after the contact, all realize direct floor suction on the common direction by cleaning wiping cloth.This is proved to be favourable when common suction nozzle operation, because, the dust catcher that can pass through to connect at this suction nozzle moves forwards or backwards in common mode, thereby and has all the time a suction channel branch to be used for the suction floor in the front that moving direction is arranged on cleaning wiping cloth.If sucking with suction channel branch bifurcated is that rear portion suction is used suction channel branch with suction channel branch and anterior a suction, in this correlation, be proved to be further favourable.

Further preferred arrangements at the sealing lip that is used for separation cleaning wiping cloth zone and floor suction areas, in conjunction with the bifurcated that sucks with suction channel branch, if the entrance of the entrance of front floor suction areas and rear floor suction areas is designed for sealing lip and the cleaning wiping cloth region separation that is bearing on the floor by one in the horizontal direction, be proved to be further favourable.Correspondingly, each is in distolateral cleaning wiping cloth edge at moving direction separately and disposes a sealing lip, and sealing lip protection preposition floor suction areas on moving direction is not affected by cleaning wiping cloth.Also so that cross flat barrier at two moving directions, become easy such as threshold thus.At this, sealing lip prevents that effectively cleaning wiping cloth from extracting or peeling off from suction nozzle bottom.Therefore further stipulate, sealing lip is designed to and can overturns by moving movement, wherein, on the travel direction of sealing lip flip portion, the suction inlet of the floor suction areas that disposes is closed basically, and on same direct of travel, another is attached troops to a unit and only acts on dividually with cleaning wiping cloth in the sealing lip of other floor suction areas.For example when suction nozzle when common direction moves, that is to say, when dust catcher moves forward usually, the sealing lip that reclines with cleaning wiping cloth of front side suction channel overturns towards cleaning wiping cloth, and cover pump orifice at edge side, can cross more easily flat barrier thus, such as threshold.On moving direction relatively the rear sealing lip placed of cleaning wiping cloth by to the suction inlet of the floor suction areas of attaching troops to a unit with respect to relatively moving of pending floor and automatic turning, and this suction inlet of complete closed basically, on selected moving direction, whole suction force concentrates on the front side and carries out the floor suction thus.When suction nozzle moved backward, the state of sealing lip changed, and therefore, whole suction force concentrates on the suction road of device profile back afterwards.

For guaranteeing that floor from cleaning is when lifting suction nozzle, may for wet, and thereby become heavy cleaning wiping cloth and can continue to be fixed on the suction nozzle, design one negative pressure is strengthened in keeping with suction channel branch, this negative pressure strengthen preferably by the cross section of floor suction areas suction entrance reduce realize.Therefore, in case suction nozzle lifts, just can close the floor suction areas fully or reduce the cross section.Closing of entrance of suction or reducing and to control by mechanical organ of its cross section.Therefore, stipulate correspondingly that whether suction nozzle lifts by the button that detects the floor contact is determined.In common floor-cleaning, this button detects floor to be cleaned.The suction entrance is opened fully, and act on that negative pressure on the cleaning wiping cloth selects enough greatly.Do not contact with the floor if button detects, will mechanically, can dwindle electrically the cross section of suction entrance by the assessment of push button signalling in case of necessity yet, thereby improve the indoor negative pressure of cleaning wiping cloth holding chamber so.Preferred closed-suction passage when suction nozzle lifts from the floor, this further by machinery, realize with the coefficient device of button, for example can rotating lid or analog.

In the middle regulation of further developing of theme of the present invention, that is, cleaner suction nozzle is configured with one or more recessed road or grooves that are communicated to suction inlet, and, design one makes recessed road be retained to structural member that small part is opened, that breathe freely simultaneously, is used for being arranged between cleaning wiping cloth and the suction nozzle.At this, the recessed road of constructing for example extends transverse to the common movement of cleaner suction nozzle or the direction of motion, in addition, and in case of necessity also can be on moving direction or with it extension in an acute angle.For example, the recessed road of a plurality of such structures can be from suction inlet until arrive the end face of cleaner suction nozzle.By these recessed roads, just can realize in common mode the suction process on floor in conjunction with the suction nozzle that is attached thereto.When wiping was worked, at least one recessed road was equipped with structural member, and this structural member makes recessed road be retained to small part near treated side the time and opens.Structural member correspondingly provides a supporting surface for the cleaning wiping cloth by the tensioning of recessed road.By partially opening and the absorption of corresponding ventilative structure continuation realization cleaning wiping cloth under condition of negative pressure.The recessed road of preferred cleaner suction nozzle possessive construction sets such structural member when wiping moves.Have separately maintenance with suction channel branch and suck in the design with suction channel branch a kind of, structural member covers in preferred design and keeps the whole SS towards the floor with suction channel branch.

Structural member is one can be from the working of plastics of following insertion suction nozzle in preferred design, be a kind of like this working of plastics furtherly, that is, it preferably covers the recessed road of possessive construction, and the in addition also further preferred suction nozzle that covers, this further partially opens recessed road and/or towards the suction inlet of treated side.Structural member can correspondingly be a plastic injection piece, and this moulding further can be by being fixedly clamped or kayser fixedly is fixed on the bottom side of cleaner suction nozzle.In addition, structural member for example also can design with the insert that can cooperate with the cleaner suction nozzle grafting integratedly, and this insert forms suction inlet and recessed road.The layout of structural member is preferred further to be selected like this, that is, this structural member struts a common plane at least almost with suction inlet floor area adjacent to the recessed road of structure or cleaner suction nozzle sticking channel part section under the insertion state.Alternatively, structural member also can be the basic module of cleaner suction nozzle, for example can or press the key motion dismounting by the switch motion.Therefore, can for example use the pin master cock when needed, make structural member pass through to descend and move into the recessed road of structure and move in case of necessity suction nozzle.In addition, also can form by structural member in principle the wiping edge of definition.For partially opening structural member, it is equipped with the suction through hole.This through hole can be designed as incision-like or boring shape, and in its elementary contour that exposes and quantitatively like this selection thereof, that is, makes cleaning wiping cloth also more reliably negative pressure maintenance when wiping is worked of disposing.

Cleaning wiping cloth directly is fixed on the structural member in a kind of preferred structure of theme.Regulation arranges an intermediate layer between structural member and cleaning wiping cloth alternatively.This intermediate layer can be coating, and for example form is anti-skidding material or the form layer that material that this class can be adsorbed on the cleaning wiping cloth better because friction increases makes of serving as reasons.This cleaning wiping cloth remains on position under the cleaner suction nozzle better according to its structure in the processing procedure of floor.Therefore, further develop middle regulation a kind of, the intermediate layer is made by the foamed material of embossing.

In this case, the intermediate layer also is used for auxiliary positioning.In addition, also strengthened the absorption of cleaning wiping cloth.Be vibration damping on for example uneven floor, stipulate preferably that further this intermediate layer is flexible adjustment, for example realize by the intermediate layer of being made by foamed material.But the balance of floor unevenness (for example slabstone seam) is realized in the intermediate layer by this flexible adjustment, realizes thus cleaning wiping cloth at least almost comprehensively supporting on floor to be cleaned.In addition, optionally, always made by silicones towards the intermediate layer of cleaning wiping cloth, further made by silicone coatings or similar anti-skidding material, described coating is on structural member.

The another kind that cleaning wiping cloth is adsorbed when cleaner suction nozzle moves improves by the airtight construction of sealant and realizes.In a kind of design of theme of the present invention, sealant extends past the whole surface of cleaning wiping cloth.Alternatively, to this further suggestion, the sealant that forms the sealant zone only partial design in cleaning wiping cloth.At this, the sealant zone especially is configured in the zone that structural member applies negative pressure, further especially is configured on the suction inlet of recessed road or cleaner suction nozzle, keeps reliably in order to load the realization cleaning wiping cloth by negative pressure.

Be proved to be especially favourable structure as a kind of, wherein, cleaning wiping cloth has a kind of profile, and the elementary contour of this profile and suction nozzle matches or almost completely matches with it at least.Created thus the wiping surface that passes through most possibly the cleaner suction nozzle load.Prerequisite is that cleaning wiping cloth only is fixed on the suction nozzle by negative pressure, for example can abandon using other to be used for fixedly clamping element or the analog of cleaning wiping cloth.Correspondingly have a kind of cleaning wiping cloth with wiping surface, the optimised gross area of this wiping surface ground uses.

In the simplest design, cleaning wiping cloth can be the fabric of doing.The liquid that is used for the wet processed floor directly is coated in the floor in this case, and works by being distributed on the suction nozzle that is equipped with cleaning wiping cloth.In a kind of the further developing of theme of the present invention, cleaning wiping cloth is the fabric that wets, and this wet fabric is correspondingly for moistening and be equipped with in case of necessity cleaning agent.In the design that substitutes, cleaning wiping cloth also can be equipped with sealing device or analog.By wet fabric Sustainable Control ground pending hard floor is drenched.The sealant that is arranged in the cleaning wiping cloth prevents that moistening cleaning wiping cloth from becoming dry because of suction.

Further preferred effect realizes thus, that is, suction nozzle inserts and cleaning wiping cloth has sucker in positive zone fixedly the time at structural member.The sucker of this front side keeps unimpeded by structural member, further preferably above the wiping cloth cover, extend, therefore, in the wiping processing procedure of carrying out by means of cleaner suction nozzle, can before the more coarse foul particle that is positioned at the suction nozzle front arrives cleaning wiping cloth, they be picked up.Prolonged thus the service life of cleaning wiping cloth.Cleaning wiping cloth can not made dirty by coarse particles or even be damaged.Therewith different or therewith combination, sucker also can be arranged on the side or be arranged in the device zone of back.

Especially in order further to improve the negative pressure in the possible suction areas, further develop middle regulation a kind of, sucker disposes a sealing lip.The sealing lip is for example made by flexible plastic or elastomeric material.According to this structure, also can realize the increase of suction function on the cleaning wiping cloth, strengthen thus the absorption of cleaning wiping cloth on structural member, and further strengthened absorption affinity by sucker.

Cleaning wiping cloth can be configured to multilayer, for example has a cleaning layer and a sealant disposed thereon, that be fixedly connected with cleaning layer.In the further developing of theme of the present invention, sealant is made by film, is further especially made by plastic sheeting, and described film is waterproof and further also preferably airtight correspondingly.The wiping of cleaning wiping cloth effectively layer is a nonwoven in preferred design, and for example PP-nonwoven or PE-nonwoven in addition, may be the microfibre nonwoven under nonexpondable situation in cleaning wiping cloth in case of necessity.

Fixing cleaning wiping cloth basically plane earth, extend abreast with pending floor level.In case of necessity, wiping edge that especially can be in corresponding structural member design cleaning wiping cloth, this has improved the scraping effect of cleaning wiping cloth on the floor.

The scheme of passing through to advise has been created aspirator/wiping arrangement that a kind of form is cleaner suction nozzle, and it is especially so that wholesomely be installed to cleaning wiping cloth and become possibility on the cleaner suction nozzle, and also becomes possibility so that wholesomely remove cleaning wiping cloth in addition.For cleaning wiping cloth is installed on the cleaner suction nozzle, the user does not need the tactile cleaning wiping cloth that catches.But so just enough, that is, the preferred profile of cleaner suction nozzle that is equipped with structural member is positioned on the cleaning wiping cloth in the same manner, and after connect dust catcher.The suction air flow that enter this moment causes the negative-pressure adsorption of cleaning wiping cloth.By closing dust catcher, cleaning wiping cloth drops, thereby for example directly falls into one for the container of removing.

In another further develops, for optimizing the location of cleaning wiping cloth on suction nozzle, make the coverage rate of cleaning wiping cloth that one texture structure be arranged, for example form is protrusion-texture structure, this structure and suction nozzle bottom side accordingly recessed-texture structure are complementary.This guaranteed that cleaning wiping cloth is accurate below suction nozzle, fit and can avoid sliding in the processing procedure fixing.This structure only is arranged on a side of cleaning wiping cloth.Effectively cleaning layer is not affected by it.

Stipulate that also cleaning wiping cloth arranges at least one at least with the edge of standing part in regional area, realize that thus cleaning wiping cloth remains on the structural member better.This standing part is designed to fix by suction in an advantageous manner.Therefore, stipulate in the design of example that at the common moving direction of suction nozzle, the front of cleaning wiping cloth and/or the partial design of back have a standing part, front area or the Background Region at suction nozzle or structural member of this partial response are inhaled into or aspirate.According to this structure, the cleaning wiping cloth that so keeps can be located with respect to the invariant position ground under the structural member when operation.

Standing part as one man designs with cleaning cloth material in a kind of structure, and this further has a sealant for improvement of suction in case of necessity.In addition, although the standing part material is consistent, yet it has structurally done change.Therefore standing part has higher density in the effective zone of cleaning wiping cloth wiping relatively, further is equipped with where necessary plastic coating.Produced thus hard or tabular edge to form standing part, wherein, also had alternatively such possibility in this connecting each other, that is, standing part is formed by duroplasts, further for example is that form is the duroplasts-edge of injection moulding.By this hard or tabular surrounded by edges suction nozzle or forward edge and/or the posterior edges of structural member, wherein, this encirclement realizes by the negative pressure in the suction areas.In addition, also can be so that the suction of the front side of suction nozzle towards the floor that will clean, for this reason, further have through hole in a kind of design of standing part according to this structure, this through hole forms the sucker towards the floor.

Standing part at least almost extends with the wiping live part plane parallel of cleaning wiping cloth ground in the respective design of the edge suction of structural member and front side and/or rear side.In the situation of structural member-surrounded by edges, the standing part of the cleaning wiping cloth of maintenance is positioned at one from the plane of effective cleaning layer plane extended spot bending, and for example crooked one until the angles of 90 degree.

In addition, the present invention relates to the cleaning wiping cloth of a kind of sticking on cleaner suction nozzle.In order to construct with improvement such cleaning wiping cloth, a sealant is set.The sealing layer prevents from having aspirated liquid by cleaning wiping cloth when cleaning wiping cloth is configured on the cleaner suction nozzle.Correspondingly, so the cleaning wiping cloth of batch production also can be for the wet-cleaning that is undertaken by cleaner suction nozzle, and wherein, cleaning wiping cloth realizes in the fixing negative pressure of only passing through to form when dust catcher moves on the cleaner suction nozzle.

The present invention also provides some features as described below in addition, they preferably with the combination of the technical scheme of claim 47, but also can only be combined with the Partial Feature of claim 47 scheme in principle, even explain individually and also have an invention meaning.Realize another improvement of the absorption of cleaning wiping cloth when cleaner suction nozzle moves by the airtight design of sealant.

In another design, cleaning wiping cloth has such device, this device preferred to cleaning wiping cloth by negative pressure fixedly replenishing on suction nozzle.These preferred mechanical devices are particularly useful for supporting the negative pressure of cleaning wiping cloth to fix.Therefore, by mechanical holder is set, when cleaning wiping cloth is interrupted in suction air flow, for example because device is closed and caused having no progeny in the suction airflow, can also continue to remain on the suction nozzle.In a kind of design, mechanical device is comprised of magic tape, and wherein, a magic tape is attached troops to a unit in cleaning wiping cloth, and another corresponding magic tape is attached troops to a unit in the suction nozzle bottom or attached troops to a unit in the support component of cleaning wiping cloth with it.When cleaning wiping cloth was made of a special textile material, when further for example being made by nonwoven cloth material, these materials itself formed the magic tape of ring-type.Further alternatively be, the mechanical latch device, this type for example namely, is designed with the kayser latch of elastic construction in case of necessity at device side, its with cleaning wiping cloth in corresponding latch hole acting in conjunction.Strengthen the latch hole edge so that reliably kayser maintenance with the acting in conjunction of kayser latch the time for example can realize by the sealant that is included in the cleaning wiping cloth.

Be proved to be especially favourable structure as a kind of, wherein, cleaning wiping cloth has a kind of profile, and the elementary contour of this profile and suction nozzle matches or almost completely is complementary with it at least.Created thus most possibly by cleaner suction nozzle load ground wiping surface.Prerequisite is that cleaning wiping cloth only is fixed on the suction nozzle by negative pressure, for example can abandon using other to be used for fixedly clamping element or the analog of cleaning wiping cloth.Correspondingly have a kind of cleaning wiping cloth with wiping surface, the optimised gross area of this wiping surface ground uses.

In the simplest design, cleaning wiping cloth can be the fabric of doing.The liquid that is used for the wet processed floor directly is coated in the floor in this case, and is distributed on the suction nozzle that is equipped with cleaning wiping cloth by wiping action.In a kind of the further developing of theme of the present invention, cleaning wiping cloth is the fabric that wets, and this wet fabric correspondingly is moistening and is equipped with in case of necessity cleaning agent.In the design that substitutes, cleaning wiping cloth also can be equipped with sealing device or analog.By wet fabric Sustainable Control ground pending hard floor is drenched.The sealant that is arranged in the cleaning wiping cloth prevents that moistening cleaning wiping cloth from becoming dry because of suction.

Cleaning wiping cloth can be configured to multilayer, for example has a cleaning layer and a sealant disposed thereon, that be fixedly connected with cleaning layer.In the further developing of theme of the present invention, sealant is made by film, is further especially made by plastic sheeting, and described film is waterproof and further also preferably airtight correspondingly.The wiping of cleaning wiping cloth effectively layer is nonwoven in preferred design, and for example PP-nonwoven or PE-nonwoven in addition, are the microfibre nonwoven when cleaning wiping cloth may repeatedly be used in case of necessity.

At this, sealant is constructed so airtightly, even if so that also can guarantee when its numerical values recited is changed by systematic influence for reliably absorption of cleaning wiping cloth and maintenance near the negative pressure of suction nozzle side.This moment, sealant was waterproof, thereby so that the water yield that may pass through can not surpass a limit, will common on the market family expenses-dust catcher be caused damage in case surpass this limit.In this sense, sealant needn't positive confinement, also for example is comprised of enough dense nonwoven, optionally realizes by being sprayed on coating on the wiping nonwoven or the film of not exclusively sealing.

Cleaning wiping cloth can infiltration water and/or cleaning agent and/or bright cleanser and/or polishing agent.The various cleaning wiping cloth types that adapt with cleaning course also can be arranged, for example a kind of type and a kind of type for polishing for wiping.

In pressing a kind of design of theme of the present invention, sealant extends past the whole surface of cleaning wiping cloth.Alternatively, to this further suggestion, the sealant that forms the sealant zone only localized design in cleaning wiping cloth.

Stipulate that also cleaning wiping cloth is provided with standing part at least in the regional area at least one edge, realize that thus cleaning wiping cloth remains on the cleaner suction nozzle better.Standing part is designed to realize fixing by aspirating in an advantageous manner.Therefore, stipulate in the design of example that namely, at the common moving direction of suction nozzle, the front of cleaning wiping cloth and/or the partial design of back have a standing part, this partial response ground can be inhaled into or aspirate at front area or the Background Region of suction nozzle or structural member.

Standing part as one man designs with cleaning cloth material in a kind of structure, and this further has a sealant for improvement of suction in case of necessity.In addition, although the standing part material is consistent, yet it has structurally done change.Therefore standing part has higher density in the effective zone of cleaning wiping cloth wiping relatively, further is equipped with where necessary plastic coating.Produced thus hard or tabular edge to form standing part, wherein, also had alternatively such possibility in this connecting each other, that is, standing part is formed by duroplasts, further for example is that form is the duroplasts-edge of injection moulding.Especially can be by suction, with this hard or tabular surrounded by edges suction nozzle or forward edge and/or the posterior edges of structural member.Alternatively, also can realize the fixing of machinery by standing part, for example clamp.Standing part another kind design in have through hole, this through hole forms the sucker towards the floor.

In a kind of design, cleaning wiping cloth infiltrates clean liquid, further is the cleaning active principle, such as surfactant.Correspondingly, the cleaning wiping cloth liquid wet-cleaning floor that after being configured on the cleaner suction nozzle, directly just can hold by sustained release.Alternatively, effective cleaning layer of cleaning wiping cloth can have the miniature capsule of preserving clean liquid and can opening by pressure.This miniature capsule a kind of design laminate of theme of the present invention be arranged on effective cleaning layer.Preserve clean liquid in each miniature capsule, such as water, add in case of necessity the cleaning action agent.During use, miniature capsule splits by the pressure on the cleaning wiping cloth, and described pressure is applied by cleaner suction nozzle.Liquid in the miniature capsule is released, and wetting cleaning wiping cloth correspondingly just in use, and wherein, cleaning wiping cloth is imbitition at first, so as afterwards constantly releasing liquid be used for wet-cleaning.

Further develop middle regulation cleaning wiping cloth theme of the present invention a kind of and made by paper material wet, multilayer, wherein, moisture or obtain in the infiltration of preserving the position by cleaning wiping cloth, or the just acquisition because set miniature capsule breaks.Because cleaning wiping cloth is made of multi-ply paper, optional particle by forming at the self-stabilization layer when moisture loads consists of, thereby can realize the removing of cleaning wiping cloth after finishing wet-cleaning.Cleaning wiping cloth further requires to promote by the friction in the wiping motion process when drying, is split into a plurality of fritters via cleaner suction nozzle, these fritters can by existing, also can be that the suction air flow of extra access is sucked by cleaner suction nozzle.At this, select when dividing the little block size of cleaning wiping cloth, need to consider the size of the suction flow orifice of reservation.Make cleaning wiping cloth be decomposed into the single fritter of dust size or grain size by division.When cleaning wiping cloth is used when just having enough sizes to be used for the general floor surface of wet-cleaning first, the floor surface in 10 to 30 square metres of zones for example, further for example 15 to 20 square metres, this structure is proved to be favourable.After the floor that finishes wet-cleaning size like this, dry cleaning wiping cloth preferably need not the further intervention of user and just is eliminated, and this further informs the user by optics and/or acoustic signal.

Different from the cleaning wiping cloth previous designs is, this cleaning wiping cloth also can be made by polyurethane foam, and it further preferably has detersive active.Therefore, for example in polyurethane foam, add surfactant and friction piece.By the rubbing action of the friction piece in the foam, in cleaning course, constantly remove the foam carry foul, and in the cleaning process, optionally also can after cleaning, aspirate by cleaner suction nozzle.

At last, the present invention relates to the method on a kind of wet-cleaning floor.

Be the wet-cleaning floor, usually need first suction process or cleaning processing are carried out in the floor, in order to siphon away coarse foul particle or analog.Just carry out wet-cleaning in common mode afterwards.

In order to simplify this process, by the present invention one cleaning wiping cloth that remains on the suction nozzle of dust catcher is set, wherein, further realize suction by means of one or more unimpeded suction channels simultaneously.This suction is preferably carried out at the fringe region of suction nozzle, further for example in positive zone, that is to say, is positioned at the zone of suction nozzle front in the common direction of motion of suction nozzle.Correspondingly at first aspirate bulky grain or analog by unimpeded suction channel, directly carry out wet-cleaning by the cleaning wiping cloth that is arranged on the suction nozzle bottom side afterwards.

Further develop middle regulation this method a kind of favourable, cleaning realizes by means of a wet-cleaning wiping cloth, and the moisture on the floor loads the outside and aspirates.In preferably arranging, the moisture on floor is carried in the contoured surface inside that the suction nozzle by dust catcher struts to carry out, and is pumped in the outside, yet is the direct contoured surface of suction nozzle and then.Correspondingly, treat wiped area, especially the wet wiped area for the treatment of is sucked all the time in advance, and this is at least on the preferred operative orientation of suction nozzle.At this, unimpeded suction channel not only is arranged on the common positive zone of suction nozzle, but also is arranged on a plurality of sides of suction nozzle, and even all sides all are furnished with unimpeded suction channel.

Also be proved to be advantageously, when the supporting of cancellation suction nozzle on the floor, be used for the negative pressure enhancing of cleaning wiping cloth-maintenances.Therefore, in the process that dust catcher lifts, guarantee, moistening and thereby become heavy cleaning wiping cloth and can also continue to be fixed on the suction nozzle.Thereby preferred only lift and so that cleaning wiping cloth when with the floor that will nurse one spacing being arranged, just needs to strengthen negative pressure at suction nozzle, this negative pressure is strengthened in preferred design closing or dwindle realization by the wet suction cross section that loads the outside in floor.The supporting of suction nozzle on the floor is further preferred to be detected by a button or analog.An expression suction nozzle lacks the push button signalling that supports and passes through mechanical couplings, yet also causes required negative pressure to be strengthened by controller for electric consumption alternatively.

Further improving thus of the cleaning effect of suction nozzle, that is, the common moving direction of suction nozzle arranges a floor pump orifice in the cleaning wiping cloth front and back relatively, wherein, according to travel direction deexcitation one suction entrance, and activates another suction entrance.Therefore, further preferably activate all the time the suction entrance in the travel direction front, and be closed in the suction entrance of same travel direction back.Correspondingly, whole suction force always concentrates on positive suction.

Cleaning wiping cloth is removed from cleaner suction nozzle or from the structural member of the cleaner suction nozzle that arranges in case of necessity after cleaning course finishes.This can in the simplest mode, namely finish with hand.A kind of design that is proved to be especially favourable that views from a sanitation point is, cleaning wiping cloth is inhaled into to realize to remove after wet-cleaning finishes, and this is by device realization of carrying cleaning wiping cloth in wet cleaning process.In preferred design, this especially increases dust catcher by the short time pumping power realization for this reason, for example can have a corresponding button.For this reason, keep that the suction nozzle of cleaning wiping cloth is corresponding to have a sucker towards cleaning wiping cloth.When usually moving, that is to say that cleaning wiping cloth remains on the cleaner suction nozzle by the negative pressure of appropriateness effect when the pumping power with standard normally aspirates.

By the independent view among Fig. 2 as can be known, in the recessed road 11 of the bottom side of suction nozzle 2 moulding one partition suction nozzle bottom 10, its passage shape ground leads to suction inlet 8, and is connected aptly with suction inlet is mobile.Shown in form of implementation in be provided with four this recessed roads 11, it is configured in the suction nozzle side in couples, and with transverse to positive 12 the one-tenths miter angles extensions of the suction nozzle of moving direction r.Recessed road 11 opens wide in suction nozzle front 12.Correspondingly, in illustrated embodiment, positive 12 places of suction nozzle are provided with the sucker 13 of four incision-like.

For processing ground, especially process carpet surface, be opened equally towards place, floor to be nursed with the suction inlet 8 mobile recessed roads 11 that are communicated with, it has a width that records transverse to recessed road 11 longitudinal extension length, this width in illustrated form of implementation, be about as much as recessed road 11 development lengths 1/3rd to sixth.

For suction nozzle 2 and cleaning wiping cloth 4 are used in combination, a final structural member 14 that supports cleaning wiping cloth 4 is set.At this, it is an insert of preferably making in plastic injection-moulded technique.

Insert or structural member 14 are complementary with the suction process section section of design in suction nozzle bottom 10, namely are complementary with the geometry that obtains by recessed road 11 and suction inlet 8.Therefore, each recessed road 11 disposes the lattice-shaped section section 15 of structural member 14, and section's section 15 of this lattice-shaped correspondingly is arranged to cover recessed road 11.Structure by lattice-shaped has produced the hole 16 that a plurality of areas reduce on opposite, hole, recessed road.

In the zone of suction inlet 8, be designed to disc-shaped closed by the structural member 14 in the form of implementation of Fig. 3.

In addition, structural member 14 is configured to, and obtains after structural member inserts recessed road 11 or suction inlet 8 and adjacent suction nozzle base portion section equal surface almost.

Insert is fixedly clamped in recessed road 11 or suction inlet 8 or kayser is fixed.

Figure 4 illustrates a kind of alternative structure of structural member 14 or insert.At this, it is not aforesaid lattice structure, but a tabular insert of for example in plastic injection-moulded technique, making, this insert is complementary with the geometry that is limited by recessed road 11 and suction inlet 8.Attaching troops to a unit in the plate-like portion section 17 in recessed road 11, remaining with the hole 18 of incision-like, be used for being connected with the circulation in recessed road 11.

In this form of implementation, the latch portion 19 of plate-like also is equipped with the hole 20 of incision-like, and this hole is towards common moving direction r, and the extension in attach troops to a unit hole 18 and recessed road 11 in section's section 17 in recessed road is orientated matchingly.

With the structure-irrelevant of structural member 14 or insert, when structural member 14 inserted suction nozzle bottom 10 or recessed road 11 and suction inlet 8, the SS 13 of suction nozzle front side stayed open.

By shown in Figure 8, the cleaning wiping cloth 4 of suction nozzle 2 configurable match profiles.With the elementary contour of suction nozzle 2 conforms to be, cleaning wiping cloth 4 also have one roughly be trapezoidal, with the obvious elementary contour of chamfering angular zone.

Cleaning wiping cloth 4 is multilayers, and specific design is two-layer, and to have form be effective cleaning layer 21 of nonwoven and the sealant 22 that extends past equally whole surface.Sealant shown in form of implementation in be a film, for example plastic sheeting.

Cleaning wiping cloth 4 so is configured on the suction nozzle 2, so that sealant 22 is between the structural member 14 of effectively cleaning layer 21 and insertion.Cleaning wiping cloth 4 only fixing on suction nozzle 2 realizes that by negative pressure this negative pressure forms in the zone at recessed road 11 and suction inlet 8 when dust catcher 1 operation.The structural member 14 that inserts provides the supporting on a plane for cleaning wiping cloth 4 when supporting self, therefore, cleaning wiping cloth 4 can not sucked the zone in recessed road 11 or the zone of suction inlet 8 by the part.

Sealant 22 is to construct airtightly, and this has further promoted the adsorption effect that negative pressure causes.In addition, sealant 22 also can waterproof the ground structure, be positioned at moisture on the floor 3 thereby prevent from picking up by cleaning wiping cloth 4.In addition, in this class design, cleaning wiping cloth 4 itself also can be used as the wet rubbing wiping cloth (rags), for example further with the cleaning agent that is contained in effective cleaning layer 21.

The configuration of cleaning wiping cloth 4 on suction nozzle 2 can realize in the simplest mode, that is, suction nozzle 2 is put on the cleaning wiping cloth 4, and then connects dust catcher 1.Obtained thus the operation of a simple and health.Removing also of cleaning wiping cloth 4 can be carried out in simple mode, as long as by closing dust catcher 1, the corresponding decline of the negative pressure in the suction nozzle 2, thereby so that the cleaning wiping cloth 4 that remains on the suction nozzle drop.

The air impermeability of the sealant 22 by cleaning wiping cloth 4 and associated cleaning wiping cloth 4, the suction force of the SS 13 that opens wide at positive 12 places of suction nozzle is improved.Can in wiping process, before cleaning wiping cloth 4 arrives this zone, coarse foul be picked up by this SS 13.Correspondingly, prepare for wiping by suction in the zone that is positioned at suction nozzle 2 fronts with corresponding usually wiping direction r on common moving direction.This does not correspondingly need to treat respectively the suction that wipe surfaces expends or sweeps.These operations are finished by means of the suction nozzle 2 of advising, be equipped with cleaning wiping cloth 4 simultaneously.

Cleaner suction nozzle 2, especially suction nozzle head 5 can be designed as pre-configured suction nozzle unit, only be used for a kind of floor type of suction process, further pre-configured for selecting to process different floor type alternatively, for example handle between hard floor processing and carpet surface processing by foot-propelled and switch, wherein, in switching, lift or fall curtain device, such as mane strip and/or sealing lip.

As shown in FIG. 10 and 11, have such possibility in the optional design of another kind, that is, cleaner suction nozzle or suction nozzle head 5 are equipped with a top cover 23 according to the configuration of selecting.What illustrate is respectively top cover 23 for the treatment of felt side.Top cover 23 is pegged graft and is fixed on the bottom side of suction nozzle head 5, wherein, the SS 13 of suction inlet 8, recessed road 11 and front side is arranged at top cover 23 interior special designs further.

By shown in Figure 10, top cover 23 disposes the described structural member 14 as single parts, further for pegging graft configuration, for this reason, structural member 14 shown in form of implementation in have block tongue 24, this block tongue when disposing to top cover 23 with corresponding draw-in groove acting in conjunction.Correspondingly, structural member 14 is optionally attached troops to a unit in top cover 23, that is to say in the situation of wishing the wet processed floor by means of the cleaning wiping cloth 4 that can dispose in addition.

As shown in figure 11, further alternatively be, top cover 23 can be simultaneously supporting structure 14 unremovably, structural member 14 and top cover 23 formed one and were used for top cover suction nozzle head 5, common, one this moment.The top cover 23 of correspondingly, so constructing is only applicable to Floor wiper and processes after configuration cleaning wiping cloth 4 in preferred design.

Figure 12 to 14 shows in addition several forms of implementation, wherein, is provided with an intermediate layer 25 between structural member 14 and cleaning wiping cloth 4.In form of implementation shown in Figure 12, intermediate layer 25 is to be made by silicones 26 towards the total surface of cleaning wiping cloth 4.At this, silicones 26 is coated in structural member 14 on the surface of cleaning wiping cloth 4 comprehensively, the contiguous lattice-shaped section section 15 that covers recessed road 11 and suction inlet 8 in described surface.As shown in figure 12, optionally intermediate layer 25 forms the lattice-shaped structure of silicones caterpillar band type in the both sides of section's section 15 of lattice-shaped.This design has improved the frictional force between structural member 14 and the cleaning wiping cloth 4, is conducive to cleaning wiping cloth 4 and is adsorbed on better on the structural member 14.This further so that cleaning wiping cloth 4 be fixed on better on the structural member 14, especially in the processing procedure of floor.At this, cleaning wiping cloth 4 remains on the position of hope reliably.

Be balance floor unevenness, in another kind of form of implementation intermediate layer 25 be set to resilient, further as shown in figure 13 by a froth bed 27 is set.This froth bed 27 preferably is not fixed on the structural member 14 not removablely, and this is preferred comprehensively covered structure spare 14 further, wherein, is further fixedly cleaning wiping cloth 4, and froth bed 27 loads by negative pressure and arranges ventilatively.Correspondingly, the suction of cleaning wiping cloth 4 is undertaken by froth bed 27 via recessed road 11.In another optional form of implementation, the partial design that froth bed 27 also only will dispose to recessed road 11 becomes ventilative, and the lateral side regions in recessed road 11 is air-locked.

Owing to select intermediate layer 25 is arranged as resilient foam layer 27, even if therefore in wet type-floor processing procedure floor 3 injustice cleaning wiping cloth 4 is at least almost covered on the floor 3 all sidedly.

Press the form of implementation among Figure 14, also have such possibility, that is, intermediate layer 25 is formed by the foamed material 28 of embossing.The foamed material 28 of this embossing has one towards the surface of cleaning wiping cloth 4 structures, and for example form is the pyramid texture structure, and this structure can make cleaning wiping cloth adsorb more firmly, and further provides the location auxiliary for cleaning wiping cloth 4.

According to aforementioned form of implementation, the foamed material 28 of embossing links to each other with structural member 14, the latter is further preferred to cover comprehensively, wherein, it is ventilative that foamed material 28 is set to part (attach troops to a unit in recessed road 11) at least, therefore, the suction of cleaning wiping cloth 4 realizes via foamed material 28, in order to cleaning wiping cloth is adsorbed on the foamed material 28.

Be arranged on sealant 22 in the cleaning wiping cloth 4 extends past cleaning wiping cloth 4 in preferred design whole surface.By the sealant 22 that arranges especially airtightly, realize that cleaning wiping cloth 4 is fixed on structural member 14 by the suction negative pressure.As shown in figure 15, in another kind of form of implementation, sealant 22 is chosen as only localized design, that is to say further formation sealant zone 29, attaches troops to a unit and be used for the air stream hand-hole of suction cleaning wiping cloth 4 in structural member 14 in this zone.Therefore, in pressing form of implementation shown in Figure 15, attach troops to a unit in lattice-shaped section section 15 designs of the recessed road 11 of suction nozzle bottom 10 or structural member 14 in the sealant zone 29 in the cleaning wiping cloth 4.Cleaning wiping cloth 4 can be constructed in sealing layer region 29 outsides at least ventilatively.

One sealing lip 30 that is arranged on front side SS 13 fronts is used for increasing the negative pressure that acts on the cleaning wiping cloth 4 in the another kind of form of implementation by Figure 16, strengthens thus the absorption of cleaning wiping cloth 4 on structural member 14.Absorption strengthens along with the increasing of suction force.

Sealing lip 30, for example form is rubber lip, and in sucker 13 front extensions, the sealing lip covers suction nozzle front 12 basically on cleaner suction nozzle 2 common moving direction r, and thus, the sucker of front side is 3 orientations towards the floor downwards.Sealing lip 30 obtains the support opposite with common moving direction r from supporter 31 shell side, that side direction is adjacent to sucker 13.

Further alternatively be, sealing lip 30 also can have the perforation of window-like, and thus, sucker 13 is not covered fully.Therefore, only the partially sealed of sucker 13 acts on negative pressure on the cleaning wiping cloth 4 for increase.

Further improve the maintenance of cleaning wiping cloth 4 on structural member 14 by design at the standing part 32 on the cleaning wiping cloth 4.This standing part 32 is designed to totally surpass necessary cleaning wiping cloth development length when flat and extend in cleaning wiping cloth 4, in preferred design, correspondingly is not that wiping acts on the floor to be nursed 3 effectively in running.To this, more preferably attach troops to a unit and dispose a standing part 32 in the edge of the cleaning wiping cloth 4 in suction nozzle front 12, be used for surrounding structural member 14 towards the edge in suction nozzle front 12.

In Figure 17 and 18 a kind of form of implementation has been shown, wherein, standing part 32 is comprised of tabular hard plastic materials and parts 33.This working of plastics for example is injection-moulded on the edge of the cleaning wiping cloth 4 of attaching troops to a unit, and preferably extends past the width of the cleaning wiping cloth 4 that records transverse to common moving direction r fully.Alternatively, tabular standing part 32 also can be by carrying out corresponding machine-shaping to Wiping material, for example by compression and/or use plastic coat.

So the standing part 32 of structure is equipped with and is seeing the through hole 34 that is incision-like transverse to moving direction r, and this through hole is attached troops to a unit to the SS 13 of suction nozzle front side to the allocation position of structural member 14 in cleaning wiping cloth 4 configurations.

The edge that structural member 14 disposes negative pressure (with reference to Figure 18) by effect when cleaner suction nozzle 2 operation realizes surrounding.At this, the standing part 32 of the cleaning wiping cloth 4 that keeps is positioned at a plane from the extended spot bending of the plane of effective cleaning layer 21, therefore, shown in form of implementation in a plane perpendicular to effective cleaning layer 21 orientations, realize local at least SS 13 of closing the suction nozzle front side by means of standing part 32.Be arranged on through holes 34 in the standing part 32 and form after this towards the floor 3 corresponding SS.

Alternatively, standing part 32 can as shown in figure 19, directly be realized by cleaning cloth material.This standing part 32 correspondingly wiping live part of relative cleaning wiping cloth 4 does not change, and correspondingly has a sealant where necessary.According to the common pliable and tough design of cleaning wiping cloth 4, the standing part 32 that protrudes from structural member 14 at edge side is sucked and overlaps to the edge of the structural member 14 that disposes when cleaner suction nozzle 2 operation.

In the drawings, the edge of the suction nozzle front side of structural member 14 disposes respectively the standing part 32 of a cleaning wiping cloth 4.In addition, another standing part 32 can be set, for example attach troops to a unit to the Background Region of suction nozzle head 5 or structural member 14, therefore, suction and the position of reversing assurance cleaning wiping cloth 4 on structural member 14 by standing part 32 make it that landing not occur.

Cleaning wiping cloth 4 in the time of on being configured in structural member 14 or suction nozzle head 5, is designed to wet, especially soaking by cleaning wiping cloth 4 usefulness clean liquids in preferred design.The simplest form of the latter is exactly water, adds in case of necessity in addition the effective material of cleaning, such as surfactant.In the process of cleaning, cleaning wiping cloth 4 discharges clean liquid constantly, is used for being coated in floor 3.

Shown in Figure 20 and 21, cleaning wiping cloth 4 is alternatively at effective cleaning layer 21, that is to say have on the surface of structural member 14 dorsad by miniature capsule 35 forms layer, described miniature capsule is preserved clean liquid.The cleaning wiping cloth 4 of equipment like this is set at cleaner suction nozzle 2, and after being placed on this cleaning wiping cloth on the floor to be cleaned 3, miniature capsule 35 breaks under the negative pressure load by cleaner suction nozzle 2 and in case of necessity dust catcher 1 effect, and discharges the clean liquid of preserving.Afterwards, clean liquid is directly by this moment or dry cleaning wiping cloth 4 absorbs, and continues to repeat in cleaning course to discharge in common mode.This structure has realized that cleaning wiping cloth 4 is just wetted when beginning the cleaning use.

Miniature capsule 35 for example forms by involucrum interception columnar structure, that made by hyperfine plastic sheeting.

Figure 22 and 23 shows the another kind of form of implementation of cleaning wiping cloth 4.Cleaning wiping cloth is made by four layers paper material in this case, and described paper material infiltrates with clean liquid.Cleaning wiping cloth 4 has enough robustnesses under this moisture state, stand also that the cleaner suction nozzle 2 that is equipped with cleaning wiping cloth 4 moves around and not damaged in wiping process.Discharge fully after the clean liquid be kept in the cleaning wiping cloth 4, cleaning wiping cloth 4 is dried up, because cleaning wiping cloth 4 selects to be made by four layers paper material, this structure causes cleaning wiping cloth 4 loose and split into irregular fritter 36 (referring to Figure 23).Now, the little cloth 36 of these dryings is behind wet-cleaning, the configuration that need not further to change cleaner suction nozzle 2 just can be sucked by this suction nozzle, these fritters for example pick up by the SS 13 of suction nozzle front side, but also hole 16 suctions of the structural member-part 15 by lattice-shaped when cleaning wiping cloth 4 splits into the cloth 36 of dust size or grain size.

In design that another substitutes, cleaning wiping cloth 4 is made by polyurethane foam, and this foam has the friction piece 37 that has added surfactant in case of necessity except detersive active such as clean liquid.This friction piece 37 mixes in the foam, and local exposing in the zone of wiping active surface.In the process of wet-cleaning, 3 dirts of collecting are received by foam from the floor, and wherein, the friction piece 37 that expose the part is further removed the foam that carries dirt gradually in the cleaning course that is undertaken by the friction on the floor 3.So the cleaning wiping cloth 4 of structure is correspondingly in the processing procedure of floor, in the situation that thickness reduces because friction is removed, little by little be decomposed, wherein, the foam beads of removing and the friction piece that decomposes otherwise in wet cleaning process directly the SS 13 by the suction nozzle front side be sucked, or in other operation, be sucked behind the wet-cleaning end-of-job.

The polyurethane foam that forms cleaning wiping cloth 4 is that negative pressure is fixed on structural member 14 or the suction nozzle bottom 10, in case of necessity in the situation of deletion structural member 14, is designed to airtightly, and further preferred anti-liquid ground designs in addition.

Figure 25 shows in another kind of form of implementation, a kind of optional method for removing the cleaning wiping cloth 4 of making dirty after finishing in cleaning.At this, cleaning wiping cloth 4 is by cleaner suction nozzle 2 whole suctions, in order to remove, for this reason, further shown in form of implementation in be the in case of necessity button 38 of design separately of dust catcher 1 configuration one, can realize in the short time the obviously air blast power of increase by this button.By the suction air flow of the increase on the cleaning wiping cloth 4 that also acts on cleaner suction nozzle 2, cleaning wiping cloth 4 is inhaled into via cleaner suction nozzle 2.

Press the form of implementation shown in Figure 22 to 25, the user need not contact just can realize cleaning wiping cloth-removing, has obtained respectively thus the cleaning scheme of a health.The dirt that holds in the cleaning wiping cloth is removed simultaneously together with cleaning wiping cloth 4.

Figure 26 to 29 shows the another kind of form of implementation of cleaner suction nozzle 2.In this form of implementation, the suction channel 39 that arrives connecting tubes 7 and is connected with the air exhauster circulation of dust catcher 1 is divided into two suction channel branches, i.e. maintenance that is used for negative-pressure adsorption cleaning wiping cloth 4 is directly used in the suction suction channel branch 41 of aspirating floor 3 with suction channel branch 40 and one.As shown in Figure 29, from flow downstream, the bifurcated 42 in the suction channel 39 directly designs the back at connecting tubes 7 basically.

Suck with suction channel branch 41 from bifurcated 42, keeping with extension above the channel branch 40, until suction nozzle front 12, at this, suck with suction channel branch 41 form one extend past suction nozzle head 5 whole width and downward towards the floor the 3 floor suction areas 43 of opening.This regional structure is the suction nozzle shape, has the incision-like entrance transverse to common moving direction r.

Keep only forming with suction channel branch 40 one downward, that is to say the fabrics maintenance chambers 44 that open towards suction nozzle bottom 10.It is annular that this fabric keeps chamber 44, also as in lid side (deckenseitig) keeps with suction channel branch 40 and suck using the lid 45 of suction channel branch 41 basically to seal by a separation, only leaves a SS 46 that is retained in the bifurcated 42.This SS 46 forms the suction channel branch 40 that fabric keeps chamber 44 relatively at last, and suction channel 39 cross sections that further also relatively are connected to the upstream reduce, and therefore, formed narrow orifice plays Venturi tube-suction nozzle.The passage narrow orifice that so forms correspondingly has been full of the suction air flow of speed rising, thereby negative pressure increases in the chamber 44 so that fabric keeps.

Fabric keeps chamber 44 to attach troops to a unit in the suction nozzle bottom 10 that is covered by structural member 14.At this, shown in form of implementation in (being equivalent to the design in the first form of implementation) relate to the structural member 14 of a lattice-shaped, this structural member further unremovably is fixed in illustrated form of implementation on the suction nozzle bottom surface of cleaner suction nozzle 2.Alternatively, the structural member 14 of fixing replaceably also is possible.

By several structural member-holes 16, the cleaning wiping cloth 4 that is arranged on structural member 14 bottom sides is fixed by negative pressure when dust catcher 1 operation, and wherein, cleaning wiping cloth 4 extends past the whole surface of structural member 14.Stipulate that in addition except the bottom suction areas 43 of suction nozzle front side, structural member 14 and cleaning wiping cloth 4 extend past all remaining suction nozzle bottom surfaces.

During through the floor suction areas 43 of front side, coarse particles and granule in the process of cleaner suction nozzle 1 moving movement on floor 3, cleaning wiping cloth 4 be sucked before plate portion contacts accordingly.In order to prevent after suction air flow is closed it also may being to fall into maintenance suction channel branch 40 owing to suck the foul particle or the dust granule that cause with unexpected eddy current in the suction channel branch 41; keep the separating device 47 and suction channel 39 by a filter shape with suction channel branch 40, further separate with suction channel branch 41 with suction.This separating device 47 shown in form of implementation in be a filter course that is arranged in bifurcated 42 zone.

From moving direction r, arrange one in floor suction areas 43 with between the cleaning wiping cloth zone that moving direction r is close to and be designed for the sealing lip 48 that is bearing on the floor 3.The sealing lip extends past the whole width of bottom suction areas 43 transverse to common moving direction r, and a vertical cross-section lengths is arranged, and this length allows according to selected moving direction upset sealing lip 48.

Sealing lip 48 has avoided cleaning wiping cloth 4 owing to the air stream via 43 suctions of floor suction areas becomes dry.In addition, sealing lip 48 for example provides a kind of servicing unit when crossing threshold when crossing flat barrier.Slide when mobile at moving direction r at cleaner suction nozzle 2, also just says the angle eyes front from the user, the free end of sealing lip 48 is positioned on the affiliated edge of cleaning wiping cloth 4, thereby so that cleaning wiping cloth 4 for example when crossing threshold, can not be torn or peel off.Sealing lip 48 correspondingly is used for auxiliary crossing simultaneously.
