Description

[0001] FLOOR AND VACCUME CLEANER CAPABLE OF COLLECTING WASTED LIQUID [0002]

More particularly, the present invention relates to a liquid guiding floor cleaner combined with a vacuum cleaner. More particularly, the present invention relates to a liquid guiding floor cleaner combined with a vacuum cleaner, To a vacuum cleaner combined with a liquid guiding floor cleaner.

Floor cleaning is primarily done by using a vacuum cleaner to inhale relatively large particles such as eraser powder and small particles such as dust and then remove contaminated stains on the floor using a wet-cloth. Floor cleaning is time-consuming to clean twice in this way, and it is known that the body should be banged up because it is necessary to bend the knee when wiping water. To solve these problems, a vacuum cleaner technology capable of cleaning vacuum cleaning and wet-cloth cleaning at the same time is being developed.

The development direction of the vacuum cleaner provided with the function of vacuum and wet-cloth can be roughly classified into two types. In the first method, a floor cleaning rotary brush is provided in the manner disclosed in Patent Document 1, the floor is polished while water is supplied to the rotary brush, and then the contaminated water is sucked by vacuum. This method has a problem that the cost of the vacuum cleaner is comparatively high because a technique of sorting and treating pollutants containing relatively large particles when they are sucked into the cleaner and a technique of keeping airtightness of the vacuum motor not to inhale water is required. Strictly speaking, this method can also be classified as performing only a cleaning similar to the cleaning of the wet-cloth, which does not provide enough advantages of the vacuum cleaning, so that the completeness of cleaning is deteriorated. The remaining method is a method disclosed in Patent Document 2, in which a wet-cloth is attached to a vacuum cleaner suction module. According to users, this method faithfully performs the function as a vacuum cleaner, but there is an inconvenience to separately wash the wet-cloth, and there is still a problem that the wet-clean does not apply sufficient pressure to complete the cleaning.

Patent Document 1: Korean Published Patent Application No. 1997-0000156 (published on Jan. 21, 1997) Patent Document 2: Korean Patent Publication No. 10-2007-0034245 (published on Mar. 28, 2007)

The present invention relates to a vacuum cleaning method and a wet-cloth cleaning method which simultaneously perform vacuum cleaning and wet-cloth cleaning. Vacuum cleaning is carried out using a vacuum groove around an outermost periphery, Which is capable of simultaneously cleaning the surface of the rotating body with water and also effectively recovering the water containing contaminants only by the rotating force of the rotating body. It is another object of the present invention to provide a liquid guiding floor cleaner which is capable of cleaning while rotating the rotating body at a relatively low rpm and generating as little noise as possible.

The object of the present invention is to provide a vacuum guiding floor cleaner for a vacuum cleaner which performs vacuum cleaning of a suction force of a vacuum motor and simultaneously cleans the bottom surface while rotating the rotary body while supplying the liquid while vacuum cleaning, A rotation shaft provided in a direction perpendicular to the bottom surface (a direction of a surface vector of the bottom surface) and rotated by a rotational force transmitted from the rotation motor shaft; A raw water reservoir for storing the clean liquid supplied to the lower surface of the rotating body, and a water tank for collecting the cleaned liquid which is separated by the centrifugal force generated when the rotating body rotates Wherein the bottom surface of the rotating body has a close contact surface which is in close contact with the bottom surface when rotated, And a liquid guide surface formed so as to be inclined so that the bottom surface and the bottom surface of the rotating body gradually become farther away from the shaft, wherein a supporting housing for supporting a rotating shaft of the rotating body, a rotating hole for exposing the rotating body, A liquid reservoir formed around the periphery of the hole for storing the liquid moving along the surface of the rotating body, and a vacuum flow path formed on the outer side of the liquid reservoir and providing a path for the vacuum intake air formed by the vacuum motor, And a lower housing coupled to the lower portion of the support housing.

The liquid guiding floor cleaner combined with a vacuum cleaner according to the present invention continuously supplies a clean liquid to the friction surface and simultaneously smoothes the liquid containing the polluted material that has been cleaned by using only surface energy and centrifugal force generated by the rotational force of the rotating body It was possible to collect it. Therefore, in the conventional floor cleaner using the wet-cloth, the wet-cloth was to be periodically washed. However, when the floor cleaner according to the present invention is used, the trouble of washing the wet-cloth is considerably eliminated.

In addition, in the cleaning header part of the liquid guiding floor cleaner combined with the vacuum cleaner according to the present invention, a rotary body for cleaning the liquid guiding floor is installed at the center of the bottom of the cleaning header, and a vacuum suction port is formed at the bottom of the outer periphery, So that the floor can be cleaned with water at the same time as vacuum cleaning. Particularly, when the bottom is cleaned by using the rotating body by forming the vacuum suction port, a sufficient pressing pressure is applied to the bottom direction.

Further, in order to forcibly suck or remove water which is likely to remain on the floor surface, a separate device such as a vacuum device for providing a strong suction force is required. However, the floor cleaner according to the present invention requires efficient cleaning The structure of the vacuum cleaner is simple, and a vacuum device for generating high or loud noises is not required. Therefore, there is an advantage in that noise is not generated to cause inconvenience to the user even when the vacuum cleaner is in operation.

It is proposed to provide a rotating body having an intermediate recovery path and to form a stepped contact surface formed on the bottom of the rotating body or to form a stopping jaw so that most contaminated liquid can be recovered through the intermediate recovery path, It is possible to recover even a single movement by the rotating body rotating at a low RPM.

The lower housing is provided with a rotating hole for exposing the rotating body downward, and has a barrier formed at a predetermined height in the upward direction along the circumference of the rotating body hole, so that the recovered liquid does not rise to the upper surface of the rotating body, The rotation speed of the rotating body can be kept low, thereby reducing the electric consumption and reducing the noise level of the vacuum cleaner.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail.

It is to be understood that the present invention is not intended to be limited to the specific embodiments but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention.

Prior to the description of the invention, the term " bottom " The term 'floor' as used in the present invention is not used in the narrow sense of the meaning of the term 'residential building' or 'office building' but is used to refer to a flattened portion to which contamination is attached and needs to be cleaned. For example, it should be understood that not only the floor of a residential or office building, but also the windows, the body of the vehicle, and the outer wall of the building are included in the 'bottom' which is meant in the present invention.

In the following, preferred embodiments, advantages and features of the present invention will be described in detail with reference to the accompanying drawings.

The liquid guiding floor cleaner combined with a vacuum cleaner according to the present invention is characterized in that the cleaning header is provided at its center with a rotary body (50) for performing water cleaning, and a vacuum groove for providing a vacuum suction force is provided outside the rotary body. In addition, the liquid guiding floor cleaner for vacuum cleaning according to the present invention has a structure in which the rotating shaft of the rotating body 50 is formed in a direction perpendicular to the floor surface (surface vector direction of the floor surface) The liquid is supplied to the rotating body, the dust is absorbed by using the bottom surface of the rotating body, and then the contaminated liquid is recovered by using surface energy and centrifugal force of the rotating body. This direction of rotation is different from the direction of rotation of the product (Model: Aqua Trio FC7070) sold by Philips. In the case of the FC7070 model, the motor rotation axis of the two blushes is formed in a direction parallel to the bottom surface, requiring a high rotational force and a considerable suction force to recover the water supplied to the floor, and a separate absorption fan is used. On the other hand, since the rotating body 50 according to the present invention rotates in the horizontal direction with respect to the bottom surface, the contaminated water can be easily recovered by using the centrifugal force.

The connecting tube portion 110 and the cleaning header portion 130 are coupled to each other so as to be rotatable within a predetermined angular range. Such a coupling structure is a coupling structure widely used in conventional floor mop cleaners and the like, and thus a detailed description thereof will be omitted. In FIG. 1, the outer case is removed to explain the structure of the cleaning header 130 in detail.

The connecting tube part 110 is formed in the shape of a hollow tube 210 whose length is adjustable by a metal material or a synthetic resin which is formed as an empty hollow part and is connected to the cleaning header part 130 through a flexible corrugated tube 220 And the other end is connected to the main body 310 through another corrugated pipe 212. A support member 250 for connecting the connection tube 110 to the cleaning header 130 is installed at the rear of the end connection tube 110 connected to the cleaning header 130 by welding. 2, the support member 250 is shown as being hinged to the cleaning header 130. However, the support member 250 may be integrally formed with a coupling structure that can freely rotate within a predetermined angular range Of course.

The connection pipe section 110 is provided with a raw water reservoir 41 for storing clean water, a pollution water reservoir 51 for storing polluted and recovered polluted water, a rotation motor 55 for providing a rotational force to the plural rotation shafts, And the pump 45 connected to the water container 41 and the contaminated water container 51 is picked up. The pump 45 supplies clean liquid supplied through the supply hose 43a from the raw water reservoir 41 to the cleaning header unit 130 through the supply hose 43b every hour and supplies the cleaned contaminated liquid Is sucked through the recovery hose 29a and stored in the contaminated water tank 51 through the recovery hose 29b. When a liquid stored in the raw water reservoir 41 is supplied to the cleaning header 130 by a natural drop method using gravity without using a separate pump 45, a predetermined amount of liquid is uniformly supplied to the rotating body 50 Can not.

A first pulley 71a is provided on the rotary shaft 63 of the rotary motor 55 and a second pulley 73a is provided on the support member 250. [ The vertical partitions 31a and 31b protruded upward are provided at the center of the support housing 30b forming the cleaning header part 130 and the vertical partitions 31a and 31b and the supporting part 250 are hinged . A first rotation bar 75 is provided between the vertical partition walls 31a and 31b and a third pulley 75a is provided on the first rotation bar 75. [

The annular bearings 21a to 21f are provided in the six through holes formed in the support housing 30b and the rotary shafts 10a to 10f of the respective rotating bodies 50 are inserted into the annular bay rings 21a to 21f from below As shown in Fig. Then, the circular gears 20a to 20f are fitted to the rotary shafts 10a to 10f protruding to the upper portion of the support housing 30b. One end of the corrugated tube 220 is inserted into another through hole 220a provided at the front side of the support housing 30b and a through hole is provided at the left and right sides of the through hole 220a through which the corrugated tube 220 is inserted The first rotating column 225a and the second rotating column 225b are installed in the through hole and the fourth pulley 77a and the fifth pulley 77b ).

A lower housing (230) having a vacuum path for forming an air flow by a vacuum pump and a liquid storage tank for temporarily storing the cleaned liquid is provided at a lower portion of the support housing (30b) to which the rotating body (50) ) Is installed. Thereafter, the attachment housing 240 is installed below the lower housing 230. The insertion grooves 231 and 241 formed in the lower housing 230 and the additional housing 240 are provided with moving wheels (not shown).

The liquid stored in the raw water reservoir 41 flows through the supply hose 43 along the pipeline along the pipeline along the hollow portion provided at the center of the rotation axis of each of the rotors 50, . The cleaned liquid temporarily stored in the liquid storage tank is designed to be recovered by the pump 45 using the recovery hose 29a fitted through the through hole of the support housing 30b.

The rotational force of the motor is designed to be transmitted to the circular gears 20a to 20g using a belt. Specifically, the belt includes a first pulley 71a provided on the motor rotating shaft 57, a second pulley 73a provided on the support member 250, a third pulley 75a, a fourth pulley 77a, The circular gear 20a, the circular gear 20b, the circular gear 20c, the circular gear 20d, the circular gear 20e and the circular gear 20f in this order and then the fifth pulley 77b, 3 pulley 75a, the second pulley 73a and the first pulley 71a. Therefore, the motor rotational force is designed so that the six circular gears 20a to 20f can be simultaneously rotated by using one belt.

4 is a partial cross-sectional view illustrating a coupling structure of a rotating body included in the liquid guiding floor cleaner according to the present invention. After the annular bearing 21b is installed in the through hole of the support housing 30b, the rotary shaft 10b is inserted into the center hollow space of the annular bearing 21b. As shown in the figure, the rotary shaft 10b is formed as a hollow space at the center thereof, and is used as a passage through which clean liquid moves downward. A circular gear 20b is inserted into the upper portion of the rotary shaft 10b with respect to the support housing 30b and a rotary body 50 is inserted into the lower portion. The liquid stored in the raw water reservoir 41 is supplied along the pipeline through the supply hose 43b and supplied so as to fall downward from the upper center of the rotation axis 10b. A bottom member 60 composed of a disc 65, a brush 61 and a cloth 63 is provided on the outer surface of the rotating body. The bottom member 60 is installed to be fixed by an elastic member 67 (rubber band, etc.) around the upper projection of the rotating body 50.

FIG. 5 is a cross-sectional view of the rotary body of the liquid-induced floor cleaner according to the present invention, showing the shape of the rotary body. The rotating body 50 is used to clean the floor surface by rubbing directly with the floor surface or using the clean liquid through the floor member, moving the cleaned contaminated water by surface energy along the surface, It is a component that functions. The rotating body may be provided in various shapes, and some of the shapes will be described. As shown in Fig. 5 (a), the rotating body 50 A contact surface A which is in close contact with a bottom surface to be cleaned in the horizontal direction and a contact surface A which is in close contact with the contact surface A ) And a liquid-guiding surface (B, also referred to as an " slope ") that moves the contaminated liquid along the surface. The upper projecting portion 52 is a portion provided to fix the bottom member 60 by an elastic member such as rubber band and the lower projecting portion 54 is provided when a bottom member having a disk as shown in FIG. This is a part for inserting and fixing the disk. The central portion 53 is a portion where a liquid guiding surface (or an 'inclined surface') is formed. The lower surface of the rotating body 50 is designed to have an adhered surface A formed so as to be in close contact with the bottom surface when rotating, and an inclined surface formed to connect the contaminated liquid with the surface energy. 5 (b) shows an embodiment in which the lower protruding portion 54 is not provided, and FIG. 5 (c) shows an embodiment in which the outermost portion of the inclined surface is bent downward Respectively.

As shown in FIG. 8 to be described later, the rotating body 50 shown in FIGS. 5 (a) and 5 (c) is an embodiment in which a separate bottom member 60 is inserted and cleaned. ) Is an embodiment in which cleaning can be performed without using a separate bottom member 60. [ In the case of the rotating body 50 in which the separate bottom member 60 is not inserted, separate processing is required to increase the surface energy. For example, the surface of the rotating body 50 is etched to have a porous surface having fine holes, or fine cilia is formed on the surface, or a material having a relatively high surface energy is coated.

6 is a cross-sectional view of the rotating body of the liquid-induced floor cleaner according to the present invention, showing the shape of the rotating body to which the intermediate recovery path is added. The rotating body shown in Fig. 5 is an example in which the contact surface A of the rotating body which is in close contact with the bottom surface is flatly formed without a step. However, when the contact surface A is flatly formed, the liquid sprayed on the bottom through the vertical central axis of the rotating body 50 can not be completely recovered by a single mopping, so that it is often possible to recover by reciprocating movement several times . In order to more efficiently recover the water sprayed on the bottom surface, an intermediate recovery path (62) is formed which is inclined upward from the bottom surface to a top surface at a position spaced a certain distance from the vertical center radius of the rotating body. When the intermediate recovery path 62 is additionally formed, about 80% of the liquid sprayed on the bottom can be recovered through the intermediate recovery path 62. The remaining 20% of the liquid was allowed to be recovered along the inclined surface after wiping the contact surface of the outer periphery of the intermediate recovery passage 62.

Fig. 6 (a) is a cross-sectional view of the rotating body, Fig. 6 (b) is a bottom view of the rotating body seen from the bottom, and Fig. 6 . As shown in Figs. 6 (a) and 6 (b), the intermediate recovery passage 62 is provided at a position having a constant radius on the vertical center axis. In order to allow as much liquid as possible to be recovered by the intermediate recovery passage 62, the region (a) from the vertical center axis to the close contact surface where the intermediate recovery passage 62 is provided is formed so as to be stepped up by a predetermined height? T Respectively. Therefore, the liquid dropped to the lower portion of the vertical center axis is displaced outward by the centrifugal force in the space formed up to the region (a), and recovered through the intermediate recovery passage (62).

The rotating body 50 shown in Fig. 6 (c) eliminates the stepped surface provided on the lower surface of the rotating body 50 shown in Fig. 6 (a) so that the adhered surface is flattened as a whole, A protruding protrusion 64 protruding downward is formed outside the protrusion 62. Therefore, the liquid dropped on the lower portion of the vertical center shaft is displaced outwardly by the centrifugal force so that most of the liquid is recovered on the intermediate recovery path 62 by the stone projections 64, and the remaining liquid is recovered along the inclined surface Respectively. The intermediate recovery path shown in FIG. 6 is configured to be formed obliquely from the lower surface of the rotating body to the upper surface, but it is needless to say that it is not necessarily formed up to the upper surface but may be formed to be formed as an inclined surface at the lower surface.

FIG. 7 is a cross-sectional view illustrating another method of fixing the supply hose to the rotating shaft included in the liquid-guiding floor cleaner according to the present invention. An annular bearing 23b is provided on the inner surface of the upper portion of the rotating shaft 10b and a supply hose 43b is fitted on the center of the annular bearing 23b. Even if the rotary shaft 10b rotates, the supply hose 43b can be held in place by the annular bearing 23b.

8 is a view illustrating an embodiment of a bottom member included in the liquid guiding floor cleaner according to the present invention. The bottom member 60 includes a disk 65 formed of a plastic material and having a hole formed at a central portion thereof, a brush 61 attached to a plurality of the disks 65 on one surface of the disk 65, And a cloth 63 to be joined so as to be connected. Although not shown in the figure, an elastic member 67 (rubber band) is provided at an end of the cloth 63. The bottom member 60 is opened upward in the state in which the elastic member 67 is stretched and inserted in the upward direction from the downward direction of the rotating body shown in Fig. 5, Is inserted into the elastic member 67 so as to be coupled thereto. A hole formed in the disk 65 is installed around the lower projection 54. Therefore, even if the bottom surface to be cleaned is uneven and uneven, the disk 65 is slightly inclined along the rugged surface, so that the cleaning can be performed easily.

The liquid supplied to the rotating body may be mixed with the polishing member so as to efficiently perform cleaning. When such an abrasive member is used, there is an effect that it can be cleaned more cleanly according to the type of the bottom surface. The artificial member may be alumina, silicon carbide, boron carbide, CBNCBN (cubic boron nitride), artificial diamond, etc. The natural member may be diamond, emery , Sephinel, petroleum stones, and silica sand may be used.

FIG. 9 is a perspective view of the lower housing of the liquid-guiding floor cleaner according to the present invention, and FIG. The lower housing 230 is provided with a rotating hole 33 at a center portion where the rotating body is installed and a circumferential surface forming the rotating hole 33 has a barrel 35 formed to protrude at a predetermined height . An outer wall 236 is formed around the outer periphery and an intermediate partition wall 234 is formed between the barrier 35 and the outer wall 236 to form a vacuum passage 235 through which suction air can flow through the vacuum motor Respectively. The liquid storage tank 237 for temporarily storing the contaminated liquid having been cleaned on the floor was formed by connecting the barrier 35 and the bottom surface of the partition wall 234 to each other.

10 is a cross-sectional view showing installation positions of a rotating body and a recovery hose included in the liquid guiding floor cleaner according to the present invention. 1 and 2, the floor cleaner of the present invention includes a first rotary shaft 10a, a second rotary shaft 10b, a third rotary shaft 10c, a fourth rotary shaft 10d, a fifth rotary shaft 10e And the sixth rotating shaft 10f are provided with respective rotating bodies 50 for cleaning the bottom surface and the liquid stored in the liquid storage tank 235 is collected by the pump 45 into the collection water tank 51 Structure is presented. FIG. 10 shows a structure in which a recovery hose 29a is provided in the liquid reservoir 237.

11 is a cross-sectional view showing installation positions of a rotating body and a recovery impeller provided in the liquid guiding floor cleaner according to the present invention. 11, instead of providing the recovery hose 29a connected to the pump 45 in the liquid reservoir 237, an annular bearing 21i is provided, a rotary shaft 10g is provided, 10g) of the impeller (88). In this structure, the circular gear 20g is provided on the rotary shaft 10g, and the rotary gear 20g is connected to the same belt together with the remaining circular gears 20a to 20f to rotate the rotary shaft 20g. The pump 45 for recovering the liquid is omitted There is an advantage to be able to.

The liquid recovered by rotating the rotating body 50 by the belt is heated up to a certain height of the space formed up to the barrier 35, and the recovered liquid becomes higher than the predetermined height. The circular gear 20g is rotated by the belt to rotate the rotary shaft 10g so that the contaminated liquid having been cleaned through the recovery hose 29 is recovered into the contamination water tank 51 while the impeller 88 is rotated will be. 11, the contaminated liquid is recovered to the contaminated water tank 51 by using the impeller. However, it is needless to say that the contaminated liquid may be recovered by using an underwater motor instead of the impeller.

FIG. 12 is an explanatory view illustrating the principle of movement of water droplets in the rotating body of the liquid-induced floor cleaner according to the present invention. The rotating body 50 is shown schematically simplified and rotated counterclockwise along the rotation axis O-O ', and reference numeral 100 denotes a liquid droplet being moved. 12, F represents the centrifugal force, Cf represents the surface energy of the surface of the rotating body (bottom member when the bottom member is provided) acting on the liquid droplet, and the centrifugal force F thereof can be expressed by the following equation .

In the equation (1), m represents the mass of the liquid droplet, R represents the rotation radius of the liquid droplet, and W represents the angular velocity.

The liquid 100 supplied to the rotating body 50 moves in the horizontal direction along the surface of the rotating body (or the bottom member) toward the outer side away from the center by the centrifugal force due to rotation as indicated by 'Case 1' The direction of movement of the liquid gradually increases from a central portion having a sloped surface (liquid guiding surface) which is formed such that the rotating body is gradually bent to the upper surface portion as indicated by a case 2 ', and as shown by' Case 3 ' The centrifugal force applied to the water becomes larger than the surface energy Cf when the liquid reaches the end of the whole, and the liquid is removed from the rotating body and recovered to the liquid storage tank 237. As shown in Equation (1), the magnitude of the centrifugal force acting on the water can be controlled by the rotation radius (R) and the rotation angular velocity (W), and the liquid reaches the end portion of the rotating body The centrifugal force previously acting on the liquid may be sufficiently larger than the surface energy of the rotating body surface (or bottom member) acting on the liquid, so that the liquid may be separated from the rotating body 50. Accurately calculating this principle makes it possible to easily determine the height of the barrier 35. Therefore, it is necessary to design the center portion formed in the rotating body 50 such that the liquid to be separated by the centrifugal force is raised along the liquid guiding surface to an appropriate height. Such a liquid-induced surface may be referred to as a nasal surface where a fluid flows along a surface consuming less energy.

The liquid collected by the rotating body 50 is stored on the bottom surface of the housing, and when the liquid is solid, the cap is opened and the liquid is collected on the bottom surface It can also be changed by pouring out the liquid. Figure 13 is a partial view of a liquid guiding floor cleaner in accordance with an embodiment of the present invention using a housing bottom as a contaminant pail. The contaminated liquid 100 on the bottom surface allows the cap 40 to be opened and then tapped and drained to the drain. In the case of Fig. 13, there is an advantage that it is not necessary to use a component such as the recovery hose 29 or the impeller 88, which transfers the liquid to the contamination water container 51. [

The liquid guiding floor cleaner described so far may be contaminated by the liquid that is filled in the liquid reservoir 237 when it is moved to clean another place after cleaning a certain place. This contaminated liquid is lost to the outside as a space formed between the barrier 35 and the rotating body 50. In order to solve such a problem in the present invention, the space between the barrier 35 and the rotating body 50 is closed. 14 is a partial cross-sectional view of a liquid guiding floor cleaner having a lid according to an embodiment of the present invention. 14A shows a state in which the space between the barrier 35 and the rotating body 50 is closed by the cover 93 as the rotating body 50 stops rotating or rotates at a very low speed, 14 (b) shows a state in which the lid 93 is separated from the space between the barrier 35 and the rotating body 50 when the rotating body 50 is rotated. The lid 93 is rotatably coupled to the rotary shaft 10f by a lid supporting shaft 91 so as to rotate within a predetermined angle range. As a coupling method for rotationally coupling the lid supporting shaft 91 to the rotary shaft 10f, a coupling method such as a hinge coupling can be applied. 14 (a), when the rotating body (strictly speaking, the rotating shaft 10f) is stopped, the lid supporting shaft 91 is pushed downward due to the weight of the lid 93, And the cover (93) covers the space between the rotating body (50). The lid 93 may be made of a material such as silicone rubber or the like. The centrifugal force acts on the lid 93 to rotate the lid support shaft 91 so as to be substantially perpendicular to the rotation axis 10f as shown in Fig. 14 (b) (93) is separated from the space between the barrier (35) and the rotating body (50).

The liquid guiding floor cleaner according to the present invention has been described so that the raw water reservoir 41 and the polluted water reservoir 51 are installed in the connection pipe portion 110. However, It is possible to change the design so as to install it in the cleaning header part 130 instead of installing it in the cleaning head part 110. It is needless to say that the present invention can be applied to a belt for transmitting the rotational force of the rotary motor 55 to the rotary shaft 10 and to other power transmission systems such as a gear system instead of using a circular gear. It is needless to say that the rotary motor 55 has been described as being mounted on the connecting tube 110 in the above description, but it may be designed to be installed in the cleaning header 130.

In addition, although it has been described that clean water is stored in the raw water tank up to now, it is needless to say that it is possible to add other cleaning liquids other than water or use other liquid materials depending on the contaminants on the bottom surface. In addition, the liquid guiding floor cleaner proposed in the present invention can be changed to a steam cleaner or a vacuum cleaner by changing the structure so that the steam cleaning and the vacuum suction cleaning can be simultaneously performed by one cleaning instead of the single use. It is also possible to easily configure the floor cleaning function by attaching it to the robot cleaner which can move by itself

15 is an assembled perspective view and a cross-sectional view in the BB 'direction of the cleaning header part of the liquid guiding floor cleaner combined with the vacuum cleaner according to the present invention. 15A is a view for explaining the role of the additional housing 240. The front lower portion of the cleaning header portion is spaced further from the ground than the other portion by the additional housing 240, The dust can be removed. In Fig. 15, arrow 300 represents the flow of intake air to perform vacuum cleaning, and arrow 400 represents the flow of liquid to perform water cleaning. The liquid for floor cleaning is supplied to the lower portion of the rotating body 50 and stored in the liquid storage tank 237 along the surface of the rotating body 50 at the center of the cleaning header portion as shown in FIG. A suction force of suction air for performing vacuum cleaning is provided outside the rotating body 50. When the vacuum suction force is set too high, there is a possibility that a liquid drop supplied to the lower portion of the rotating body 50 may be vacuumed . This problem can be solved by forming a blocking wall 243 in the attachment housing 240 as shown in Fig. 15 (c). Or by inserting the replenishing material 245 with a rubber material such as EDPM in a hatched area on the bottom surface of the attachment housing as shown in Fig. 15 (d).
