Description

  The present invention first relates to a combination of a suction nozzle and a cleaning sheet of a vacuum cleaner, in which the suction nozzle of the vacuum cleaner has a suction port, and the cleaning sheet is held by the suction nozzle, particularly through decompression.

  Vacuum cleaner suction nozzles are known. They find application as home vacuum cleaner heads, especially for the decontamination of floors and even carpets or hard floors. In addition, suction nozzles for processing above the floor are also known. These are connected to the vacuum cleaner in principle via suction hoses or the like for the blotting process of higher ones, such as shelf bases or the like. In the suction portion of the suction nozzle, a reduced pressure is generated that enables the cleaning sheet to be held during operation. As a result, regulated suction nozzles for wet cleaning such as hard floors, eg flooring floors, tile floors, etc. can be used.

  In view of the above state of the art, the technical problem of the present invention is found as an arrangement to improve this kind of combination.

  This problem is first and fundamentally solved by the subject matter of claim 1. Here, it is proposed that the cleaning sheet has a sealing layer to prevent wicking of liquid. As a result of this configuration, it is also possible to clean the surface with water through the suction nozzle of the vacuum cleaner. Improved cleaning results through water cleaning are targeted. The liquid used for cleaning is carried into the suction nozzle of the vacuum cleaner via the suction air flow that is preferably required for the cleaning sheet, and then carried away into the cleaner that produces the suction air current. In order to prevent this, the sealing sheet is provided with a sealing layer. This functions as a separation layer.

  Furthermore, important features are described, preferably in combination with the features of claim 1. However, they can in principle be important either alone or in combination with the single features of claim 1.

  In another configuration of the subject of the present invention, the suction nozzle of the vacuum cleaner has two suction channel systems downstream toward the cleaning sheet, thereby generating a vacuum for holding the cleaning sheet And direct floor suction is provided. With this configuration, the suction air flow brought about during operation is diverted on the nozzle side, one for holding the cleaning sheet and the other for direct floor suction. Here, in the configuration in which the opening of the holding suction channel system faces the floor, the cleaning sheet that is preferably completely covered is attached to the sheet holding chamber of the assigned holding suction channel system at least substantially at a single reduced pressure. Make the room attached and closed. The relatively high flow velocity during the suction operation increases the dynamic pressure of the entire system and conversely reduces the static pressure. This reduced static pressure causes suction into the walls in the flow channel and, as a result, in the above case, to the sheet holding chamber that is closed when the cleaning sheet is applied. This appears as a static pressure that is lower than the background static pressure. This acts in a sheet holding chamber for attaching the cleaning sheet preferably under reduced pressure. A uniform vacuum is applied to each part of the sheet holding chamber through the proposed division of the suction channel system. As a result, uniform pressure reduction works over the entire surface of the cleaning sheet on which pressure reduction acts. Furthermore, a preferred suction force is achieved in the suction channel system via the separate suction channel system. The suction force is also not reduced by sucking the cleaning sheet and sticking it to the suction nozzle.

  The suction channel systems are arranged side by side so that they are arranged at least partially vertically in the preferred configuration and at least overlap in the projection with respect to the nozzle bottom or in the projection on the cleaning floor in the operating state. Is arranged. In a preferred configuration, the holding suction channel system here extends below the suction channel system. Here, in another configuration, the holding suction channel system simultaneously forms a sheet adhering chamber at the same time, while the suction channel system is configured to have a tubular cross section, for example, and is guided on the holding suction channel system. More preferably, the former end forms a suction nozzle-like suction port over the entire width of the suction nozzle orthogonal to the normal operation direction. This suction port provided in the suction channel system is preferably arranged at its own tip with respect to the normal operating direction of the suction nozzle. The reason for this is that when the suction nozzle is moved forward in the normal operating direction, coarser dust particles are sucked up before the floor gets wet.

  Further, the suction channel system extends at least partially in the horizontal direction, and further extends in the horizontal direction with respect to the normal operation direction. And, for example, the surface above the nozzle bottom and oriented horizontally at a slight distance to the nozzle bottom is the suction channel in which the sheet holding chamber of the holding suction channel system is also placed in front of it in the normal operating direction. Divide the channel system.

  The cleaning sheet portion is more preferably separated from the floor suction portion in a horizontal direction by a blade-like packing provided for placing on the floor. In a preferred configuration, this extends orthogonally to the normal operating direction of the suction nozzle and further to the entire width of the nozzle orthogonal to the normal operating direction. With this configuration, first, the cleaning sheet preferably containing a liquid is supported by a suction air flow sucked through a suction portion of the floor before drying. As a result of the configuration of the blade packing, the air suction partitions at least the nozzle portion placed in front of the blade packing in the normal operating direction. Here, more preferably, this kind of blade-like packing is also provided near the portion that sucks in the floor. In addition, the blade packing serves as a structural aid in overcoming door sills or other flat obstacles. Since the suction nozzle is moved forward in the normal operation direction, that is, the suction portion of the floor first moves on the floor to be cleaned, the blade-like packing is opposed to the cleaning sheet that follows the operation direction rearward at its free end. It is placed over the end portion to be covered, or instead, at least as necessary, the gap formed between the cleaning sheet and the nozzle bottom is covered. This avoids tearing or peeling of the cleaning sheet when overcoming door sills or other flat obstacles. The blade packing lifts the cleaning sheet on the obstacle from the viewpoint of lifting.

  In another configuration, the cleaning sheet is preferably held by mechanical means of the suction nozzle so as to complement the holding through the reduced pressure. This mechanical holding is particularly useful to assist in holding the cleaning sheet via reduced pressure. Depending on the construction of the mechanical holding means, the application of the cleaning sheet can also be obtained after blocking the suction airflow, for example by closing the housing. The mechanical means comprises a ride-on closure member in a predetermined configuration. Here, the ride-on closing member is assigned to the cleaning sheet and the corresponding other ride-on closing member is assigned to the holding member assigned to the nozzle bottom or the cleaning sheet. In the case where the cleaning sheet is made of a special material, for example, a wool material, this material itself forms an annular climbing closure member, while the housing side is provided with a corresponding climbing closure member in the form of a hook with a chin. ing. Further, instead, the mechanical means is formed with a notch engaging means, and further, for example, an engagement hook having spring elasticity is formed on the casing side as necessary, and functions in cooperation with the corresponding opening of the cleaning sheet. It is formed to do. Strengthening of the peripheral edge of the engagement opening for reliably holding the lock associated with the engagement hook is achieved, for example, by a sealing layer formed on the cleaning sheet.

  In order to increase the pressure reduction in the holding suction channel system and in the sheet holding chamber to which the cleaning sheet is attached, in another configuration of the object of the present invention, the holding suction channel system is configured to It has been proposed to have channel narrowing. As a result of the narrowing of the airflow channel, an increase in the airflow velocity is achieved in this portion, which leads to an increased pressure reduction in the cross-sectional portion of the sheet holding chamber. The narrowing of the airflow channel acts like a Venturi tube. In another preferred embodiment, the narrowing of the airflow channel is provided at the branch of both suction channel systems. However, the narrowing may instead be formed before the upstream branch with respect to the cleaning sheet.

  In order to prevent dust particles carried through the suction channel system from entering the holding suction channel system, the latter further comprises a filter-like separating means from the suction channel, more specifically from the suction channel system. It is proposed to be separated via The separating means on the filter is preferably a filter member such as a layer of paper or wool having filter properties. Alternatively, the separating means may also consist of a fine grid. In other configurations, the filter-like separating means are preferably arranged interchangeably at the part where both vent channel systems diverge.

  A configuration in which the suction nozzle is formed as an opening of the suction channel system before and after the cleaning sheet with respect to the normal operating direction is particularly advantageous. As a result, direct floor suction is performed both in the normal operating direction both before and after the floor to be cleaned touches the cleaning sheet. This appears as an advantage in normal handling of the suction nozzle. This is because at this time, the suction nozzle is moved back and forth in a normal manner through the connected vacuum cleaner, so that the suction channel system is arranged in front of the cleaning sheet in the operating direction to suck the floor. It is. This cooperation appears as an advantage when the suction channel system is branched into a front suction channel system and a rear suction channel system.

  In a further preferred configuration in which the blade-like packing separates the cleaning sheet part from the floor suction part, this appears in conjunction with the branching of the suction channel system as a further advantage in the following cases. That is, when the suction port of the suction part of the front floor and the suction port of the suction part of the rear floor are separated from the cleaning sheet in a horizontal direction through a blade-like packing formed so as to be placed on the floor It is. Thereby, blade-like packing is assigned to each end portion of the front cleaning sheet in each operation direction. The packing protects the cleaning sheet at the suction portion of the floor disposed in front of the operation direction. This also makes it easier to get over both obstacles over a flat obstacle, such as a door sill. The blade-like packing here effectively prevents the cleaning sheet from being pulled away or scraped away from the bottom of the suction nozzle. Further, it is proposed that the blade-like packing is formed so as to be deflectable through a moving operation. Here, in a given direction of movement, the deflecting member of the blade-like packing substantially closes the suction opening of the assigned floor cleaning part, while the other assigned to the other floor suction part in this direction. The blade packing moves only away from the cleaning sheet. For example, in the movement of the suction nozzle in the normal operation direction, that is, in the normal forward movement of the vacuum cleaner, the blade-like packing placed on the cleaning sheet is deflected toward the cleaning sheet at the front suction portion, and the end of the sheet Cover the side. This makes it possible to easily get over a flat obstacle, for example, a door sill. The blade-like packing located behind the cleaning sheet in the operation direction falls substantially in the direction of the suction port facing the suction portion of the floor through a relative movement with respect to the floor to be cleaned and is substantially completely closed. Thus, in the selected operating direction, the total suction force is directed to the suction portion of the floor on the tip side. In the backward movement of the nozzle, the blade-like packing is thereby switched to a state in which the total suction force is directed to the suction on the rear side with respect to the bottom surface of the housing.

  Strengthen the vacuum in the holding suction channel system to ensure that the suction nozzle continues to be held by the suction nozzle when it is lifted from the floor to clean the suction nozzle and gets wet with moisture as needed It is proposed. This strengthening is achieved by reducing the cross-sectional area of the suction port of the suction part of the floor. The suction part of the floor is completely closed or the open area is reduced as soon as the suction nozzle is lifted. Closing the inlet cross-section or reducing the area may be adjusted via a mechanical member. In this context, it is proposed that the lifting of the suction nozzle is detected via a contact detection mechanism that detects contact with the floor. In a normal floor cleaning operation, the contact detection mechanism detects the floor to be cleaned. The suction opening is selected to have a size that is sufficiently open and ensures a reduced pressure acting on the cleaning sheet. When contact with the floor is removed by the contact detection mechanism, for example, mechanically, however, it is also detected electrically by evaluating the contact signal as necessary, and the cross-sectional area of the suction port is reduced, so that the seat holding chamber The decompression of is strengthened. Preferably, the suction channel is closed in the course of lifting the suction nozzle off the floor, which is further closed via mechanical means that function in conjunction with the contact detection mechanism, such as a deflectable damper or the like.

  In another configuration of the object of the present invention, the suction nozzle of the vacuum cleaner is formed with one or a plurality of grooves connected to the suction opening, and the predetermined groove is at least partially opened, but also allows air to pass therethrough. It is proposed that a forming part is provided. The grooves formed here extend, for example, perpendicular to the normal operating direction or movement direction of the suction nozzle of the vacuum cleaner, but also in the operating direction or at an acute angle to this as required. It is growing. For example, a plurality of such grooves formed out of the suction port reach the surface on the tip side of the suction nozzle of the vacuum cleaner. Through these grooves, the floor can be suction-cleaned in an ordinary manner in cooperation with the suction ports connected to these. In the water wiping cleaning, at least a structure forming portion that holds and holds a groove at least partially with respect to a surface to be cleaned is provided in the groove. The structure forming portion is provided so as to coincide with the support surface of the cleaning sheet stretched through the groove. The application of a cleaning sheet requiring further decompression has been achieved through a structure that is partially open and allows air to flow accordingly. Preferably, all the grooves formed with the suction nozzle of the vacuum cleaner are provided with such a structure forming part during the wiping operation. In a configuration where the holding suction channel system and the suction channel system are separated, the structure forming portion covers the entire suction opening facing the floor of the holding suction channel system in a preferred configuration.

  In a preferred configuration, the structure forming portion is a resin member that can be attached to the inside of the suction nozzle from the lower side, and is preferably a resin foil that preferably covers all formed grooves, and more preferably covers the suction port. . Here, the foil covers the lower side with respect to the direction of the floor surface to be cleaned of the opening of the groove and / or the suction port. The structure forming portion is a resin molded member that can be held by engaging or locking the suction nozzle of the vacuum cleaner on the lower side. Further, the structure forming portion can be integrally formed with an attachment member that can be inserted into and attached to the suction nozzle of the vacuum cleaner and forms a suction port and a groove. The structure of the structure forming portion is more preferably adjusted as follows. That is, in the state where this is attached to the formed groove or the suction port of the suction channel system for holding the suction nozzle of the vacuum cleaner, the portion near the bottom of the suction nozzle spreads at least in a substantially common plane. Alternatively, the structural member may be a basic component of the suction nozzle of the vacuum cleaner, and may be removable via, for example, a switch operation or key operation. For example, when the operation of the switch via the foot is a condition, the structure forming portion may enter the groove formed or the suction port as necessary. Furthermore, basically, a cleaning sheet whose surface is determined via the structure forming portion may be formed. For a partial opening of the structure-forming part, this provides a suction penetration notch. These (notches) are formed in the shape of a slot or a round hole, and the shape and number of the free bottom surface are adjusted so that the cleaning sheet to be attached is firmly held under reduced pressure during the wiping operation. Good.

  The cleaning sheet is directly held by the structure forming portion in the preferred configuration of the present invention. Instead, an intermediate member is disposed between the structure forming portion and the cleaning sheet. This intermediate member may be a layered member, for example, a slip-preventing member or a layered member made of such a material, and the frictional force may be increased to improve the holding of the cleaning sheet. With this configuration, the cleaning sheet is favorably held at the attachment position of the suction nozzle of the vacuum cleaner during floor cleaning. In other configurations, it has been proposed that the intermediate member comprises an injection molded foam.

  In this case, this is also used as a positioning auxiliary member. Furthermore, the sticking property of the cleaning sheet is also improved. For example, it has been proposed that elasticity is introduced into the intermediate member, more specifically, the intermediate member is formed of a foamed member in order to overcome an uneven floor surface with an elastic force. Through the intermediate member into which the elasticity is introduced, the unevenness of the floor (for example, tile joints) is made uniform, so that the cleaning sheet is placed on the entire surface to be cleaned at least substantially. Furthermore, in any case, the intermediate member facing the cleaning sheet is made of silicon resin, or a layer of silicon resin, or a similar friction generating material, and these laminated members are brought on the structure forming portion.

  Further improvements regarding the application of the cleaning sheet during operation of the suction nozzle of the vacuum cleaner have been achieved through the hermetic construction of the sealing layer. The sealing layer extends over the entire surface of the cleaning sheet in the subject configuration of the present invention. Instead, in this regard, the sealing layer is further configured to simply form the sealing layer portion in parallel within the cleaning sheet. The sealing layer portion is assigned to the pressure reducing portion of the structure forming portion, and more particularly to the suction nozzle groove or suction port of the vacuum cleaner, in order to securely hold the cleaning sheet by applying a reduced pressure.

  Particularly preferred is a configuration in which the cleaning sheet has an outer shape that matches or at least matches the bottom shape of the suction nozzle as much as possible. Thereby, the sheet surface drawn through the suction nozzle of the vacuum cleaner can be made the widest. By providing that the cleaning sheet is held by the suction nozzle only under reduced pressure, it is preferable to not consider fixing the cleaning sheet excessively via a clamp or the like. As a result, the cleaning sheet has a water wiping surface that is optimally used on the entire surface.

  The cleaning sheet may be a dry sheet in the simplest configuration. In this case, the liquid for wiping the floor is directly distributed to the floor and dispersed by the action of a suction nozzle to which a cleaning sheet is attached. In another configuration of the subject of the present invention, the cleaning sheet is consequently a wet sheet comprising moisture and possibly a cleaning member. Further, the cleaning sheet is provided with an airtight means or the like in other configurations. Through the wet sheet, moisture is continuously adjusted and supplied to a hard floor to be cleaned. The sealing layer provided in the cleaning sheet prevents the moisture contained in the cleaning sheet from being dried.

  In the case where the structure forming portion is attached to the suction nozzle and the cleaning sheet is held, the suction nozzle has a suction opening in a front portion thereof, thereby achieving a further preferable effect. The suction opening on the tip side is held away from the structure forming portion and more preferably extends above the surface of the cleaning sheet, so that the rough dust particles in front of the suction nozzle are removed in the water wiping cleaning process. Can be sucked before it reaches the cleaning sheet. Thereby, the usable time of the cleaning sheet can be increased. The sheet is not soiled by coarse dust and is not damaged as well. Alternatively or in combination, the suction opening may also be provided laterally or rearward.

  In order to increase the pressure reduction particularly at the suction portion as much as possible, it has been proposed in other configurations to provide a blade-like packing at the suction opening. This blade-like packing is made of, for example, a soft plastic or a rubber material. With this configuration, it is possible to increase the pressure reducing action on the cleaning sheet, thereby increasing the sticking of the cleaning sheet to the structure forming portion and further increasing the suction force through the suction opening.

  The cleaning sheet is formed in multiple layers, and has, for example, a cleaning active layer, and a sealing layer firmly fixed to the cleaning active layer thereon. This sealing layer, in another configuration of the subject of the invention, consists of a foil, in particular a resin fill, which is consequently impermeable to water and more preferably airtight. In a preferred configuration, the cleaning active layer of the cleaning sheet is made of a fiber material, for example, PP (polypropylene) or PE (polyethylene) material, and if necessary, the cleaning sheet is made of a microfiber material as much as possible. Become.

  The cleaning sheet held is basically flat and spreads in parallel to the floor to be cleaned. In some cases, in particular, a sheet peripheral edge that enhances the polishing action of the cleaning sheet on the floor by adjusting the structure forming portion may be formed in the cleaning sheet.

  Through the proposed configuration, the suction unit or the wiping unit is particularly suitable for the suction nozzle of the vacuum cleaner, which can insert the cleaning sheet hygienically into the suction nozzle of the vacuum cleaner and even more hygienically discard the cleaning sheet. Realized in a manner. The user need not grab the sheet to attach the cleaning sheet to the suction nozzle of the vacuum cleaner. It is achieved that the suction nozzle of the cleaner into which the structure forming part is inserted is arranged on the cleaning sheet, preferably in line with the contour, and then the cleaner is activated for use. The suction sheet brought here causes the cleaning sheet to be stuck under reduced pressure. By stopping the cleaner, the cleaning sheet is removed and, for example, directly discarded into a waste container.

  In other configurations, in order to optimally align the cleaning sheet with the suction nozzle, the male member is inserted below the suction nozzle in conformity with the structure forming portion that becomes the ceiling member of the cleaning sheet, for example, a female-type structural member. A mold structural member may be proposed. This is exactly congruent, so that the cleaning sheet is securely placed under the suction nozzle against shifting during operation. This structure forming part is provided on the cleaning sheet only on one side. Thus, the cleaning active layer remains unaffected.

  It has also been proposed that the cleaning sheet is provided with a fixing member at least partially on the periphery, thereby improving the fixing of the cleaning sheet to the structure forming part. In a preferred embodiment, the fixing member for fixing is fixed by suction. In an exemplary configuration, a part of the cleaning sheet, which is forward and / or rearward with respect to the normal operating direction of the suction nozzle, forms a fixing member, which is consequently sucked by the front or rear part of the suction nozzle or structure forming part. Or have been suggested to be inhaled. With this configuration, the cleaning sheet held in this manner is arranged below the structure forming portion so as not to be displaced during operation with respect to the attachment position.

  The securing member is formed to match the material of the cleaning sheet in a given configuration, thereby providing a cleaning sheet that helps improve suction in a given case. Further, in this connection, the fixing member is made of the same material, but may have a different structure. Further, the fixing member has higher airtightness than the cleaning active portion of the cleaning sheet, and may further have a resin layer depending on the case. This provides a rigid or flat fastening member periphery for forming the fastening member. Further, in this connection, the fixing member may be made of hard resin instead, or may be formed so that the peripheral edge of the hard resin protrudes. This hard or flat peripheral edge is captured by the peripheral edge on the front side and / or the rear side of the suction nozzle or structure forming part. Here, this trapping is realized in the suction part via reduced pressure. Furthermore, with this configuration, suction on the tip side of the suction nozzle is directed to the floor to be cleaned, and for that purpose, in a predetermined configuration, the fixing member is provided with a through-notch portion that forms a suction opening directed to the floor. It's okay.

  The fixing member spreads flatly at least with respect to the active layer of the cleaning sheet in a configuration corresponding to the structure forming portion and the peripheral portion on the front end side and / or the rear side. When surrounding the periphery of the structure forming portion, the fixed portion of the held cleaning sheet transitions from a region where the cleaning active layer spreads flat to a surface bent to an angle of 90 °, for example. .

  The present invention further relates to a cleaning sheet held by a suction nozzle of a vacuum cleaner by decompression. In order to configure this type of cleaning sheet to be improved, a sealing layer is provided. The sealing layer prevents liquid from being sucked from the cleaning sheet when the cleaning sheet is attached to the suction nozzle of the vacuum cleaner. As a result, the cleaning sheet thus formed can also be used for water wiping cleaning through the suction nozzle of the vacuum cleaner. Here, the fixing of the cleaning sheet to the suction nozzle of the cleaner is achieved only by the reduced pressure formed during the operation of the cleaner.

  Furthermore, features are described which are preferably important in combination with the features of claim 47, but in principle may be important in the combination of features of claim 47 and single features or alone.

  Another improvement with respect to sticking the cleaning sheet during operation of the suction nozzle of the vacuum cleaner has been achieved through a configuration in which the sealing layer is airtight.

  In another configuration, the cleaning sheet has means that preferably complement the retention on the suction nozzle via reduced pressure. These preferred mechanical means are particularly useful in assisting the holding of the cleaning sheet by reduced pressure. Through the configuration of the mechanical holding means, the cleaning sheet is applied to the suction nozzle when the suction airflow stops, for example, after the suction airflow stops by turning off the power of the apparatus. The mechanical means is made of Velcro (registered trademark) in a predetermined configuration. Here, one magic tape (registered trademark) is attached to the cleaning sheet, and the other corresponding magic tape (registered trademark) is attached to a holding member assigned to the nozzle bottom or the cleaning sheet. In particular, when the cleaning sheet is made of a fiber material, for example, a synthetic fiber material, this material itself may form a magic tape (registered trademark) consisting of a ring. Further alternatively, the mechanical means is a locking means, more specifically, a hook having spring elasticity as required on the housing side and functioning in conjunction with a corresponding engagement opening of the cleaning sheet. . The strengthening performed to securely lock the engagement opening functioning with the hook is achieved, for example, by providing a sealing layer on the cleaning sheet.

  A special advantage arises in a configuration in which the cleaning sheet has an outer shape that matches or at least matches the bottom shape of the suction nozzle as much as possible. Thereby, the suction of the sheet surface through the suction nozzle of the vacuum cleaner is most preferably performed. By taking the condition that the cleaning sheet is attached to the suction nozzle only through decompression, extra measures such as fixing the cleaning sheet via a hook or the like are unnecessary. As a result, the entire cleaning surface of the cleaning sheet is optimally used.

  Further, in the simplest configuration, a dry sheet may be used. The floor-wiping liquid is in this case distributed directly through the suction nozzle, which is brought directly to the floor and fitted with a cleaning sheet. In another configuration of the subject according to the invention, the cleaning sheet is correspondingly a wet sheet provided with a liquid and optionally a cleaning member. Further, the cleaning sheet may be provided with a sealing means or the like in another configuration. Through the wet sheet, continuously adjusted moisture is provided on the hard floor to be cleaned. The sealing layer provided on the cleaning sheet prevents the moisture contained in the cleaning sheet from being sucked and dried.

  The cleaning sheet may be configured in multiple layers, and may include, for example, a cleaning active layer and a sealing layer provided on the cleaning active layer and fixed to the cleaning active layer. This sealing layer, in another configuration of the object according to the invention, consists of a foil, for example a corresponding liquid, more preferably a resin foil which also has an airtightness. In a preferred configuration, the cleaning active layer of the cleaning sheet is made of a fiber material such as a PP fiber material or a PE fiber material, and if necessary, a microfiber material in the case where the cleaning sheet is used in multiple layers.

  Here, the sealing layer is held airtight so as to ensure that the reduced pressure generated on the nozzle side attracts the cleaning sheet and holds it securely even in the fluctuations within the system conditions. Here, the sealing layer is waterproof so that the mixed water that has passed through rises to the edge and does not damage a normal manual household vacuum cleaner. In this regard, the sealing layer need not be uniformly and completely sealed, for example it may consist of a fiber material having a sufficient sealing property, and instead a layer partially formed on the fiber material. Or it may be achieved by a foil that does not completely seal.

  The cleaning sheet may be continuously supplied with water, cleaning means, brightener and / or abrasive. In addition, the cleaning sheet may be changed according to the type of cleaning. For example, it is possible to change the sheet and the abrasive.

  The sealing layer extends over the entire surface of the cleaning sheet in the predetermined configuration of the object according to the invention. Instead, in this regard, it is further proposed that the sealing layer is only partially formed by connecting the sealing layer portions within the cleaning sheet.

  It is also proposed that the cleaning sheet is provided at least partly with a fixing member at least at the periphery, so that the retention of the cleaning sheet on the suction nozzle of the cleaner is improved. In a preferred embodiment, a fixing member for fixing is sucked and fixed. In a preferred configuration, the front portion and / or the rear portion of the cleaning sheet with respect to the normal suction nozzle push-out direction form a fixing member, and this (fixing member) is sucked at the corresponding front end side or rear side portion of the suction nozzle. It has been proposed to be attached or sucked.

  The fixing member is made of a material that is integral with the cleaning sheet in a predetermined configuration, thereby providing a sealing layer that is further used to improve the suction force. Furthermore, in this connection, the fixing member may consist of the exact same material. However, the structure can be changed. Furthermore, the fixing member may have a higher sealing property than the cleaning active portion of the cleaning sheet, and a resin layer may be provided as necessary. From this, a hard or plate-like periphery is obtained for the formation of the fixing member. Here, furthermore, in relation to this, there is a possibility that the fixing member is formed of a hard resin, and further, for example, a fixing member may be formed in a peripheral edge shape made of a hard resin and partially connected. Via this hard or plate-like periphery, the front or rear periphery of the suction nozzle can be supplemented in particular by suction. Instead, a mechanical fixation, for example a hook, can be achieved via the fixing member. In other configurations, the securing member has a through-notch that forms an opening directed to the floor.

  The cleaning solution is immersed in the cleaning sheet in a predetermined configuration. As a result, after the cleaning sheet is attached to the suction nozzle of the vacuum cleaner, the floor can be immediately wiped with water by supplying the liquid already stored. Alternatively, the cleaning active layer of the cleaning sheet may have microcapsules that store the cleaning solution and can be opened by pressure. These microcapsules are provided in layers on the cleaning active layer in the subject configuration according to the invention. In each microcapsule, a cleaning solution such as water is stored with a cleaning activator mixed as necessary. In use, the microcapsule collapses due to the pressure applied to the cleaning sheet, and this pressure is brought through the suction nozzle of the cleaner. The microcapsule can contain a liquid, and the cleaning sheet is first supplied with moisture corresponding to the time of use. Further, here, the cleaning sheet first sucks up the liquid in order to continuously wipe and clean.

In another configuration of the subject according to the invention, it is proposed that the cleaning sheet consists of a multi-layered paper stock with water added. Here, hydration is achieved in advance by storing the liquid in the cleaning sheet, or is first achieved by crushing the supplied microcapsules. Instead of a cleaning sheet consisting of multiple layers of paper material, instead of forming a stable grain while releasing water, the cleaning sheet can be discarded for the next water cleaning Sex has been achieved. The cleaning sheet breaks up when it is dried and is further broken into small pieces with the help of friction caused by the sheet moving process through the suction nozzle of the vacuum cleaner. The size of the split cleaning sheet piece is adjusted here in consideration of the maintained opening for the suction airflow. Through splitting, the cleaning sheet is broken down into small pieces of dust or cork size. In particular, the cleaning sheet has such a size that the cleaning sheet can be used for a single use and, for example, a floor surface in an area of 10 to 30 square meters, for example, 15 to 20 square meters, with respect to normal floor cleaning. Sometimes it is preferred.
By being combined with such wide floor cleaning, the dry cleaning sheet is preferably discarded without further intervention of the user's hands, which is further transmitted to the user with optical and / or acoustic signals. Be notified.

  Instead of the construction of the cleaning sheet described above, it consists of a polyurethane foam, which (foam) may more preferably have a substance effective for cleaning. For example, a polyurethane foam may be charged with a surfactant and an abrasive. Through the frictional action of the abrasive in the foam, the foam with dust attached during cleaning is continuously scraped off and sucked by the suction nozzle of the cleaner during or after cleaning.

  Finally, the present invention relates to a method for cleaning floors.

  In order to remove coarse dust particles or the like for floor water wiping, a floor wiping or wiping of the floor is generally required first. Thereafter, water cleaning is finally performed by a normal method.

  In order to make these processes into one, according to this invention, the cleaning sheet hold | maintained at the suction nozzle of the cleaner is proposed. Here, furthermore, suction takes place simultaneously via one or several open suction channels. This suction is preferably performed at the peripheral edge of the suction nozzle, and for example at the tip, ie the tip of the suction nozzle in the normal operating direction. As a result, first, coarse dust or the like is sucked in through the opened suction channel, and then water cleaning continues immediately through the cleaning sheet provided on the floor surface of the suction nozzle. Done.

  In another preferred configuration of the method, the cleaning is performed via a wet cleaning sheet and the suction is performed outside the part where water is supplied to the floor. The cleaning supply to the floor, in a preferred configuration, takes place in the bottom surface stretched through the suction nozzle of the vacuum cleaner, while the suction takes place outside the bottom surface of the suction nozzle, but immediately leads to this surface. To be done. As a result, the area to be wiped, particularly the area to be wiped with water, is always sucked in advance. The open suction channels are not only provided here at the normal tip of the suction nozzle, but also on all sides of the suction nozzle, depending on the number of open suction channels. It may be arranged up to the side.

  Moreover, it is preferable that pressure reduction is strengthened from the viewpoint of holding the cleaning sheet when lifting the suction nozzle on the floor. For example, during the lifting of the suction nozzle, it is ensured that the cleaning sheet that has become heavier and contains water sticks to the suction nozzle again. Enhanced pressure reduction is only preferred when lifting the suction nozzle and is therefore required when there is a gap between the cleaning sheet and the floor to be cleaned. This enhanced vacuum is achieved in a preferred configuration by closing or reducing the cross-section of the inlet outside the floor to which moisture is supplied. Placement of the suction nozzle on the floor is more preferably detected via a contact detection mechanism or the like. The disappearance of the contact detection signal also leads to mechanical linkage, but instead to linkage via electrical state detection means for enhancing the decompression as desired.

  Further improvement in the cleaning performance of the suction nozzle is achieved by suctioning the floor before and after the cleaning sheet with respect to the normal operating direction of the suction nozzle. Here, one suction port is disabled regardless of the operation direction, while the other suction port is enabled. More preferably, the front inlet in the operating direction is always active, while the rear inlet in the same operating direction is closed. As a result, all the suction forces are directed to the tip side suction each time.

  After completion of the cleaning process, the cleaning sheet is removed from the suction nozzle of the vacuum cleaner or the structure forming portion of the suction nozzle of the vacuum cleaner provided as necessary. This is most easily done by hand. In particular, from the viewpoint of hygiene, a configuration in which the cleaning sheet is sucked for disposal after completion of the water wiping cleaning, and a configuration in which the cleaning sheet is sucked in through the unit that supports the cleaning sheet during the water wiping cleaning are preferable. This is done in a preferred configuration, in particular by raising the suction power of the cleaner for a short time. For this purpose, the vacuum cleaner may be provided with a corresponding contact detection mechanism, for example. For this purpose, the suction nozzle that holds the cleaning sheet has a suction opening that faces the cleaning sheet. In normal operation, i.e., normal suction with controlled suction power, the cleaning sheet remains attached to the suction nozzle of the vacuum cleaner via a moderately acting vacuum.

  The present invention will now be described in more detail with reference to the accompanying drawings, in which only several embodiments are shown. With reference to FIG. 1, first a vacuum cleaner 1 with a suction nozzle 2 for the treatment of a floor 3 is described. The illustrated embodiment is directed to the carpet suction nozzle of the nozzles. The features of the nozzle 2 and further the combination of the nozzle 2 and the cleaning sheet 4 described below, however, can also consider a hard floor cleaning nozzle. Here, in them, a sinkable cleaning brush for selective cleaning according to, for example, a hard floor and carpet can be attached to the suction nozzle 2.

  The suction nozzle 2 is composed of a nozzle head 5 that is substantially placed on the floor 3 and a nozzle body 6 that connects the nozzle head 5 to the cleaner 1. Here, the nozzle body 6 is provided with a connection adapter 7 for fluidly connecting the suction nozzle 2 to the vacuum cleaner 1 and electrically as required. The suction channel extends as it exits the connection adapter 7 through the nozzle body 6, where the channel opens into the suction port 8 in the nozzle head 5.

  The connection adapter is provided at the end of the upper nozzle body 6, and the connection adapter 7 is rotated around an axis orthogonal to the normal operation direction r of the suction nozzle 2 in the rotation portion. A traveling roller 9 that supports one of the nozzle bodies 6 on the floor 3 is further provided toward the rotating shaft.

  As can be understood from the single drawing of FIG. 2, a groove 11 for cutting the nozzle bottom 10 is provided on the lower side of the suction nozzle 2, and this 11 is connected to the suction port in a channel shape and is fluidized therewith. Responsible connection. In the illustrated embodiment, four such grooves 11 are provided, which are paired on the nozzle side and at the nozzle tip 12 at an angle of about 45 ° in a direction perpendicular to the operating direction r. It is growing towards. These grooves 11 are open toward the nozzle tip portion 12. As a result, in the illustrated embodiment, the nozzle tip 12 is provided with four slot-like suction openings 13.

  The grooves 11 fluidically connected to the suction openings 8 are equally open with respect to the direction of the floor to be cleaned for floor cleaning, in particular for carpet cleaning. The opening width corresponds to a region measured in a direction perpendicular to the longitudinal direction of the groove 11, that is, about one third to one sixth of the length of the groove in the illustrated embodiment.

  In order to use the suction nozzle 2 in combination with the cleaning sheet 4, a structure forming portion 14 that finally supports the cleaning sheet 4 is provided. Here, this refers to a mounting member, preferably manufactured by a method of injection molding a resin.

  The mounting member or structure forming part 14 is adjusted to the cleaning element formed in the nozzle bottom 10 and is also adjusted to the geometry formed by the groove 11 and the suction nozzle 8. Each groove 11 is assigned a lattice portion 15 of the structure forming portion 14, and the lattice portion 15 is configured to coincide with and cover the groove 11. A plurality of flat and contracted openings 16 are formed with respect to the groove openings through the lattice structure.

  In the suction port 8 portion, the structure forming portion 14 is configured to be closed in a disk shape in the embodiment of FIG.

  Furthermore, after the structure forming portion 14 is mounted in the groove 11 or the suction port 8, the structure forming portion 14 has a substantially flat surface with the nozzle bottom in the vicinity.

  The mounting member is held in the groove 11 or the suction port 8 so as to be sandwiched or engaged.

  FIG. 4 shows another structure of the structure forming portion 14 or the attachment member. In this case, the above-mentioned lattice structure is not intended, but rather a flat mounting member formed by injection molding of resin. The latter is adjusted to a geometric shape determined by the groove 11 and the suction port 8. In the flat member 17 assigned to the groove 11, a slot-like opening 18 is provided for ventilation with the groove 11.

  The disk-like closing member 19 is also provided with a slot-like opening 20 in this embodiment. This 20 is oriented in the normal operating direction, while the opening 18 is oriented in the longitudinal direction of the groove 11 in the member 17 assigned to the groove.

  Regardless of the structure of the structure forming part 14 or the mounting member, when the structure forming part 14 is attached to the bottom 10 of the nozzle or the groove 11 and the suction port 8, the suction opening 13 on the tip side of the nozzle remains open.

  The suction nozzle 2 is contoured with the cleaning sheet 4 as shown in FIG. 8 so that it can be attached. Corresponding to the bottom shape of the suction nozzle 2, the cleaning sheet 4 also has a thick and rounded end, and has a substantially trapezoidal outline.

  The cleaning sheet 4 is formed in multiple layers, specifically two layers, and includes a cleaning active layer 21 in the form of a fiber material layer and a sealing layer 22 that extends over the entire surface as necessary. The latter 22 is a foil, for example a resin foil, in the illustrated embodiment.

  The cleaning sheet 4 is attached to the suction nozzle 2 so that the sealing layer 22 is positioned between the cleaning active layer 21 and the attached structure forming portion 14. Holding the cleaning sheet 4 to the suction nozzle 2 is realized only by decompression. This decompression occurs in the groove 11 or the suction port 8 during the operation of the cleaner 1. The attached structure forming portion 14 is supported evenly by itself, and the cleaning sheet 4 is mounted in a plane. As a result, the cleaning sheet 4 is partially sucked into the groove 11 or the suction port 8 portion. Don't be.

  The sealing layer 22 is configured to be airtight, and this further supports the suction effect due to the reduced pressure. Furthermore, the sealing layer 22 may also be configured so as not to allow water to pass therethrough, so that liquid uptake on the floor 3 may be avoided via the cleaning sheet 4. Further, in a similar configuration, the cleaning sheet 4 is also proposed as a wet sheet, and further, for example, a cleaning means accommodated in the cleaning active layer 21 may be provided.

  The cleaning sheet 4 is attached to the suction nozzle 2 by the simplest method in which the suction nozzle 2 is placed on the cleaning sheet 4 and then the cleaner 1 is operated. As a result, simple and hygienic handling is possible. Further, the cleaning sheet 4 is removed by the simplest method that stops the vacuum cleaner 1 and correspondingly reduces the reduced pressure in the suction nozzle 2 until the cleaning sheet 4 held therein falls. It may be configured.

  Through the sealing layer 22 of the cleaning sheet 4 and the airtightness of the cleaning sheet 4 associated therewith, the suction force is enhanced at the suction opening 13 that remains open at the nozzle tip 12. Through this suction opening 13, coarse dust can be sucked before the cleaning sheet 4 reaches the surface in the water wiping process. As a result, the normal operation direction of the suction nozzle 2, as well as the front part in the normal water wiping direction r, is pretreated by suction for water wiping. As a result, there is no waste because a series of suction and wiping away from the surface to be wiped away. Rather, these cleaning steps are cleared at once via the suction nozzle 2 according to the proposal in which the cleaning sheet 4 is provided.

  The suction nozzle 2, particularly the nozzle head 5, may be formed as a pre-configured nozzle unit in order to normally suck only the floor-shaped one. These 2 and 5 may further be configured to selectively clean against different floor qualities. Here, for example, in response to cleaning of a hard floor and cleaning of a carpet floor, the tip curtain means, for example, a brush ribbon and / or packing ribbon, is switched up and down to selectively perform cleaning.

  As shown in FIGS. 10 and 11, yet another configuration is possible in which the suction nozzle or nozzle head 5 is provided with a mounting member 23 depending on the configuration selected. In each case, a mounting member 23 for carpet floor cleaning is shown. The attachment member 23 is inserted and held in the nozzle head 5 from below. Further, in particular, a suction nozzle 8, similarly a groove 11, and a suction opening 13 on the distal end side are formed in the mounting member 23.

  As in the configuration in FIG. 10, the structure forming portion 14 can be attached to the attachment member 23 as a separate member, and can be further inserted. For this purpose, the structure forming part 14 has a locking member 24 in the illustrated embodiment, which functions integrally with the corresponding locking receiving part when attached to the mounting member 23. As a result, the attachment portion 23 is selectively attached to the structure forming portion 14, that is, the cleaning sheet 4 can be further attached when water wiping cleaning is desired.

  Alternatively, the mounting member 23 can be removed simultaneously with the structure forming portion 14 as shown in FIG. 11, so that the structure forming portion 14 and the mounting member 23 form a common and integral mounting member for the nozzle head 5. It can be made. As a result, the mounting member 23 configured in this manner may be suitable only for cleaning the floor after wiping the cleaning sheet 4 in a preferred configuration.

  FIGS. 12-14 shows the other Example in which the intermediate member 25 is arrange | positioned between the structure formation part 14 and the cleaning sheet 4. FIG. In the embodiment illustrated in FIG. 12, this intermediate member is configured as a silicon resin member 26 that faces the cleaning sheet 4 in any case. Here, the silicon resin member 26 may be provided over the entire upper surface of the structure forming portion 14 facing the cleaning sheet 4 and in the vicinity of the lattice portion 15 covering the groove 11 and the suction port 8. Alternatively, the intermediate member 25 may provide a silicon resin rope-like lattice portion on either side of the lattice portion 15 as shown in FIG. As a result of this configuration, the friction between the structure forming portion 14 and the cleaning sheet 4 increases, which causes the cleaning sheet 4 to be more favorably attached to the structure forming portion. This further leads to better attachment of the cleaning sheet 4 to the structure forming portion 15 particularly in the floor cleaning process. Here, the cleaning sheet 4 is securely held at a desired position.

  In order to compensate for the unevenness of the floor, the intermediate member 25 is formed of an elastic body in another embodiment, and is further configured as a foam layer 27 as schematically shown in FIG. The foam layer 27 is preferably attached to the structure forming portion 14 so as not to fall off, and more preferably, the foam layer 27 covers the entire surface of the structure forming portion 14. Here, the foam layer 27 is further adjusted to allow air to pass in response to the reduced pressure in order to more firmly fix the cleaning sheet 4. As a result, suction of the cleaning sheet 4 through the groove 11 is performed from here through the foam layer 27. In still another configuration, the foam layer 27 may be assigned only to the groove 11 to allow air to pass while the groove 11 side region may be configured to pass air.

  As a result of selecting that the intermediate member 25 is configured in the form of an elastic foam layer 27, even if there is unevenness of the floor 3 during the water wiping cleaning, at least the floor 3 is covered with the cleaning sheet 4 almost entirely. Can do.

  Further, as in the embodiment in FIG. 14, the intermediate member 25 can be constituted by a foamed member 28 formed. The foam member 28 faces the cleaning sheet 4 and has a surface on which a structure, for example, a pyramidal structure is formed. This structure makes it possible to improve the sheet sticking ability, and also helps to align the cleaning sheet 4.

  The molded foam member 28 is bonded to the structure forming portion 14 as a result of the above embodiment, and more preferably covers the latter 14 in its entirety. Here, the foam member 28 is at least partially assigned to the groove 11 and adjusted to allow air to pass through, so that the cleaning sheet 4 is drawn through the foam member 28 for application to the foam member 28. .

  The sealing layer 22 provided on the cleaning sheet 4 extends over the entire surface of the cleaning sheet 4 in a preferred configuration. The cleaning sheet 4 is fixed by the suction to the structure forming part 14 through the hermetic sealing layer 22 that is particularly airtight. As shown in other embodiments in FIG. 15, the sealing layer 22 may instead be only partially formed. That is, the other sealing layer portion 29 to be attached may be formed in the opening used for suction of the cleaning sheet and in the structure forming portion 14 for air flow. In the embodiment shown in FIG. 15, the sealing layer region 29 is formed in the cleaning sheet 4 so as to be assigned to the groove 11 of the nozzle bottom 10 or the lattice portion 15 of the structure forming portion 14. Outside the sealing layer portion 29, the cleaning sheet 4 is configured to allow at least air to pass therethrough.

  The packing ribbon 30 provided in front of the suction opening 13 on the front end side is used to increase the reduced pressure acting on the cleaning sheet 4 in another embodiment in FIG. 16, and thus the structure forming portion 14 of the cleaning sheet 4 is used. Adhesion to is strengthened. This is accompanied by an increase in suction force.

  The packing ribbon 30 extends, for example, in the form of a rubber ribbon in front of the suction opening 13 in the normal operation direction r of the suction nozzle 2, and this 30 substantially closes the nozzle tip 12 side. With this, the suction opening on the tip side tends to be directed downward with respect to the direction of the floor 3. The packing ribbon 30 receives the support in the normal operation direction r by a plate-like element 31 that partitions the housing side on the suction opening 13 side.

  Further alternatively, the packing ribbon 30 may also have a window-like slot so that the suction opening 13 is not completely covered. Sealing of the suction opening 13 to increase the reduced pressure acting on the cleaning sheet 4 is achieved only partially.

  Further improvement of the holding of the cleaning sheet 4 to the structure forming portion 14 is achieved by providing the cleaning sheet 4 with a fixing member 32. In the case of the configuration of the cleaning sheet 4 that is flat as a whole, such a fixing member 32 is provided over a necessary section of the cleaning sheet. As a result, this 32 does not affect the cleaning action on the floor 3 which is cleaned during operation in the preferred configuration. In this connection, more preferably, a fixing member 32 is provided at the end of the cleaning sheet 4 assigned to the nozzle tip 12 so as to surround the end of the structure forming portion 14 on the nozzle tip 12 side.

  17 and 18 show an embodiment in which the fixing member 32 is made of a flat hard resin member 33. FIG. This is distributed, for example, at the end where the cleaning sheet 4 is attached, and preferably extends completely over the entire width of the cleaning sheet 4 perpendicular to the normal operating direction r. Alternatively, the flat fixing member 32 may also be formed through a corresponding processing of the cleaning sheet material, such as compression and / or lamination with resin.

  The fixing member 32 formed in this manner is provided with a slot-like through-out portion 34 in a direction orthogonal to the normal operation direction r. This 34 is attached to the suction opening 13 on the tip end side of the nozzle in a state where the cleaning sheet 4 is attached to the structure forming portion 14.

  Enclosing the assigned end of the structure forming part 14 is achieved via a vacuum that acts during operation of the suction nozzle 2 (see FIG. 18). Here, the holding member 32 of the cleaning sheet 4 held is transferred to a plane deformed from the planar surface of the active layer 21, for example, a surface facing downward with respect to the active layer 21 in the illustrated embodiment. ing. At least partial closure of the suction opening 13 on the tip side of the nozzle is achieved via the fixing member 32. The through-notch 34 formed in the fixing member 32 thereby forms a corresponding suction opening directed towards the floor 3 side.

  Alternatively, the securing member 32 may also be realized directly from the cleaning sheet material, as further shown in FIG. As a result, the fixing member 32 does not change compared to the active portion of the cleaning sheet 4 and therefore has a sealing layer as necessary. As a result of the configuration of the generally loosened cleaning sheet 4, the fixing member 32 protruding over the end side of the structure forming portion 14 is sucked during the operation of the suction nozzle 2 and assigned to the structure forming portion 14. Cover the periphery.

  The fixing member 32 of the cleaning sheet 4 assigned to the end portion of the nozzle of the structure forming portion 14 is illustrated. Furthermore, the other fixing member 32, for example, the nozzle head 5 or the rear portion of the structure forming portion 14 is allocated and provided. As a result, the position of the cleaning sheet 4 on the structure forming portion 14 is ensured not to slip by the suction and surrounding of the fixing member 32.

  In a preferred configuration, the cleaning sheet 4 is already moist when attached to the structure forming part 14 or the nozzle head 5, for example, the cleaning sheet 4 is particularly humidified with a cleaning solution. The cleaning solution is most easily composed of water, and a material useful for cleaning such as a surfactant may be added as necessary. During the cleaning process, the cleaning sheet 4 continuously sprays the cleaning solution on the floor 3.

  Instead, the cleaning sheet 4 may have a cleaning active layer 21 as schematically illustrated in FIGS. 20 and 21. That is, this 4 has a layer made of microcapsules 35 for storing the cleaning solution on the surface facing the direction opposite to the structure forming portion 14. After the cleaning sheet 4 thus prepared is mounted on the suction nozzle 2 and placed on the floor 3 to be cleaned, the microcapsule 35 is subjected to the action of pressure through the suction nozzle 2 and, if necessary, the cleaner 1. Burst to expose the stored cleaning solution. The cleaning solution is thereby drawn directly through the cleaning sheet 4 which has been dried so far and is continuously supplied in a conventional manner repeatedly during the cleaning process. As a result of this configuration, the cleaning sheet 4 is humidified by the beginning of use for cleaning.

  The microcapsule 35 is formed of, for example, a container made of an extremely thin resin foil and formed in a carrot shape.

  22 and 23 show another embodiment of the cleaning sheet 4. This consists in this case of a multilayer paper stock which is humidified with a cleaning solution. In this humidified state, the cleaning sheet 4 has a necessary strength. In addition, the strength requires that the suction nozzle 2 provided with the cleaning sheet 4 is not worn by the back-and-forth movement in the water wiping process.

  After the cleaning solution stored in the cleaning sheet 4 is sufficiently discharged, the cleaning sheet 4 dries out. This is based on the selected configuration of the cleaning sheet 4 and splits the cleaning sheet 4 from a multi-layered paper material into a large number of small and irregular sheet pieces 36 (see FIG. 23). These now dried sheet pieces 36 are sucked in through the nozzle 2 without further changes in the structure of the suction nozzle 2 in conjunction with water wiping cleaning. This is performed, for example, through the suction opening 13 on the tip end side of the nozzle. However, when the cleaning sheet 4 is disassembled into a sheet piece 36 having a size of dust or rice husk, the cleaning is performed also through the openings 16 of the lattice portion 15 of the lattice structure portion.

  In another configuration, the cleaning sheet 4 is made of polyurethane, which has an abrasive 37 to which a surface active agent is added, if necessary, in addition to a substance useful for cleaning such as a cleaning liquid. This abrasive 37 acts without matching and is partially deposited on the surface of the cleaning active layer. During the wiping cleaning, the dust carried away from the floor 3 is removed through the bubbles. Here, the abrasive 37 that is partially exposed during the cleaning of the floor 3 using the abrasive continuously carries away bubbles covered with dust. As a result, in the floor cleaning process, the cleaning sheet 4 configured in this manner is then disassembled while reducing the thickness of the cleaning sheet by removing it while scraping it. Here, the carried-off foam particles and the removed abrasive are directly removed through the suction opening 13 on the tip end side of the nozzle in the cleaning process already in progress, or alternatively in another cleaning process after the completion of the water wiping cleaning. Dried.

  The polyurethane foam constituting the cleaning sheet 4 is attached to the structure forming portion 14 or the nozzle bottom 10 via a reduced pressure, and thus is airtight, more preferably waterproof while omitting the structure forming portion as necessary. Configured.

  FIG. 25 shows another method for removing the dirty cleaning sheet 4 after cleaning in another embodiment. Here, the cleaning sea 4 is sucked in via the suction nozzle 2 in order to be removed as a whole. For this purpose, a key button 38, which is assigned to the cleaner 1 in the illustrated embodiment and is configured separately as required, is provided. Through this 38, the input power of the fan can be increased in a short time. The cleaning sheet 4 is sucked in through the suction nozzle 2 through the suction air flow acting on the cleaning sheet 4 rising in the suction nozzle 2.

  The removal of the cleaning sheet as in the embodiment illustrated in FIGS. 22 to 25 is performed without touching the user, so that a hygienic removal solution is achieved in each case. Together with the cleaning sheet 4, the housed dust is also removed.

  26 to 29 show another embodiment of the suction nozzle 2. In these, the suction channel 39 penetrating the connection adapter 7 and fluidly connecting with the suction fan of the cleaner 1 is divided into two suction channel systems. That is, this 39 is separated into a holding suction channel system 40 that is used for attaching and holding the cleaning sheet 4 under reduced pressure, and a suction channel system 41 that allows the floor 3 to be directly sucked. . As can be seen from the schematic configuration in FIG. 29, the bifurcation 42 is formed immediately behind the connection adapter 7 in the suction channel 39 in a substantially downstream direction of flow.

  Starting from the branch portion 42, the suction channel system 41 extends above the holding suction channel system 40, and this 41 is connected to the nozzle tip 12. Here, the suction channel system 41 forms a floor suction portion 43 that extends over the entire width of the nozzle head 5 and opens downward toward the floor 3. This is formed in the shape of a nozzle having a slot-like opening directed in a direction orthogonal to the normal operation direction 4.

  The holding suction channel system 40 forms a sheet holding chamber 44 that opens completely on the lower side, that is, on the side opposite to the nozzle bottom 10. The seat holding chamber 44 is substantially closed on the ceiling side only by leaving the suction airflow outlet 46 in the branch portion 42 via the deck 45 that separates the suction channel system 40 for holding from the channel system 41 for suction. So that it is surrounded. The suction airflow outlet 46 is smaller in cross section than the suction channel system 40 for holding finally forming the sheet holding chamber 44 and further compared to the suction channel 39 connected upstream of the flow. The bottleneck thus formed acts like a Venturi tube. The channel bottleneck thus formed results in an increased pressure reduction in the sheet holding chamber 44 in contact with the high velocity suction airflow.

  The sheet holding chamber 44 is assigned to the nozzle bottom 10 side and is covered with the structure forming unit 14. Here, in the illustrated embodiment, this 14 is intended for the lattice-shaped structure forming portion 14 corresponding to the configuration of the first embodiment. In the illustrated embodiment, the lattice-shaped structure forming portion 14 is fixed so that it does not come off on the bottom surface of the suction nozzle 2. Instead, the structure forming portion 14 that can be fixed in a replaceable manner may be used.

  The cleaning sheet 4 disposed on the lower side of the structure forming portion 14 is stuck and fixed by decompression during operation of the cleaner 1 through the plurality of structure forming portions-openings 16. Here, the cleaning sheet 4 further extends over the entire surface of the structure forming portion 14. Further, it is proposed that the structure forming portion 14 and the cleaning sheet 4 spread over the entire remaining surface of the nozzle bottom, excluding the floor suction portion 43 on the tip side of the nozzle.

  During the movement of the suction nozzle 1 of the vacuum cleaner on the floor 3, coarse particles or fine particles are sucked up via the floor suction portion 43 on the front end side before coming into contact with the corresponding floor partial cleaning sheet 4. In order to prevent coarse dust or sucked particles falling in the suction channel system 41, which may occur in some cases after the suction air flow is cut, from entering the holding suction channel system 40, the following configuration is provided. The That is, the holding suction channel system 40 is divided into a suction channel 39 and a suction channel system 41 via a filter-like separation means 47. This separating means 47 is a filter element disposed in the branching portion 42 in the illustrated embodiment.

  With respect to the operation direction r, a blade-like packing 48 formed to be placed on the floor 3 is provided between the floor suction portion 43 and the cleaning sheet portion connected to the operation direction r. This 48 has a cross section that extends over the entire width of the floor suction portion 43 in a direction orthogonal to the normal operation direction r and extends in the vertical direction. This cross section allows deflection of the blade packing 48 regardless of the selected operating direction.

  The blade-like packing 48 prevents the cleaning sheet 4 from being dried through the airflow sucked through the floor suction part 43. Further, the blade-like packing 48 provides an auxiliary means when overcoming a flat obstacle such as a door sill. When the suction nozzle 2 of the vacuum cleaner is pushed and moved forward in the operation direction r, that is, viewed from the user, the open end of the blade-like packing 48 rests on the end of the assigned cleaning sheet 4. As a result, the cleaning sheet 4 is not torn or divided, for example, over the threshold. As a result, the blade-like packing 48 also serves as a climbing aid.

  As typically illustrated in FIG. 30, each is (48) attached to both the nozzle tip 12 and the back side of the nozzle to provide a floor suction 43. Therefore, the individual floor suction portions 43, 43 'are assigned to the blade-like packings 48, 48'. Here, the blade-like packing 48 forward in the operation direction does not affect the accompanying floor suction portion 43 each time. This 48 overlaps the end of the facing cleaning sheet 4 and the blade-like packing 48 ′ at the rear in the operation direction is directed in the same direction, so that the floor suction part 43 ′ arranged at the rear in the operation direction is sealed. (See FIGS. 31 and 32). Whenever the floor suction part at the rear in the operation direction is closed so as to be sealed, all the suction force is thereby directed to the floor suction part 43 at the front in the operation direction each time. As a result, the absorption of coarse dust or dirt on the floor 3 in front of the cleaning sheet 4 is improved.

  As schematically shown in FIG. 30, floor suction portions 43, 43 ′ are respectively provided in front and rear of the suction nozzle 2 of the vacuum cleaner, so that these are rearward in the front suction channel system 49. Are connected in fluidics via a branch of a suction channel 39 connecting the suction channel system 50 of the other. The branch 42 therefore has three suction channel systems in addition to the suction channels 39.

  33 and 34 show an embodiment in which contact between the suction nozzle 2 of the vacuum cleaner and the floor is detected. Each of the following descriptions is related to floor suction on the front side. In the other suction performed as necessary at the rear portion of the suction nozzle 2 of the vacuum cleaner, the same mechanism is taken.

  In order to detect contact with the floor, a contact detection mechanism 51 is provided on the front end side of the nozzle in front of the floor suction portion 43 in the normal operation direction r. This 51 has the contact tray 52 mounted on the floor 3 in the state which contacted the floor. A pin 53 extending vertically upward from the contact plate 52 passes through the nozzle bottom 10. A clamp-like closing plate 54 extending in the longitudinal direction of the nozzle is connected to the other free end of the pin 53.

  A pressure spring 55 surrounding the pin 53, one end supporting the contact plate 52 and the other end supporting the nozzle bottom 10 presses the contact detection mechanism 51 downward in the vertical direction. As a result, this is compressed by the corresponding vertical sinking of the contact detection mechanism 51 when the suction nozzle 2 of the cleaner is placed on the floor 3. In this state of the contact detection mechanism, the closing plate 54 is held in an open state as shown in FIG.

  By lifting the suction nozzle 2 of the vacuum cleaner from the floor 3, the support on the floor to the contact detection mechanism 51 or the pressure plate 52 is removed.
