Description

[0001] Wet and dry type moving cleaner [0002]

The present invention relates to a wet-type mobile cleaner, and more particularly, to a wet-type mobile cleaner capable of flexibly and conveniently cleaning the floor of a common place such as a home or an office.

In general, in offices and public places such as airports and terminals with a large population of people, due to temporal / spatial constraints, it is virtually impossible to passivate the environment using the labor of individual cleaning companies. In other words, a quick and clean work must be performed. However, when the cleaning work is performed by hand or by mopping or mopping, the cleaning worker's body suffers repeatedly due to repeated work, resulting in the efficiency and speed of the cleaning work. In order to solve such a problem, a vacuum cleaner using a mechanical device has appeared and is widely used and used. For example, by cleaning the vacuum cleaner with the vacuum cleaner on board, Wet mobile cleaners or dry mobile cleaners (aka, lease-kicks or auto-mops) are being manufactured and used to clean the floor quickly and easily.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an external view showing a conventional mobile cleaner, wherein FIG. 1A is a conventional wet-type moving cleaner, and FIG. 1B is a conventional dry-type moving cleaner. As shown in FIG. 1 (A), the wet type moving cleaner has a structure in which steam is discharged from a lower portion of the cleaner, which is capable of sucking foreign substances such as dust, Or a wet cleaning unit (Korean Utility Model Registration No. 20-0401003 etc.) such as a vacuum or a scrubber (cleaning and dust collecting apparatus) using water in liquid form and a wheel for moving the cleaner, , The cleaner can simply move to the place he wants to clean by operating the handle by sitting on the seat of the cleaner and carrying out the desired operation. As shown in Fig. 1B, the dry-type moving cleaner is disposed in front of the wheels for movement, and is provided with oil or the like, which is elongated in a direction perpendicular to the traveling direction of the cleaner to collect foreign matter and further polish the floor In addition, like the above-mentioned wet type moving cleaner, the cleaning worker can simply move to a place he wants to clean by operating the steering wheel sitting on the seat of the cleaner, and can perform a desired work .

However, in the case of the wet type mobile cleaner, it is easy to discharge moisture, but there is a limit to sucking the discharged water back into the interior of the cleaner. Therefore, moisture remains in the place where the cleaner passes, There is concern that people may be injured by slipping. In addition, when the vacuum cleaner used in the wet vacuum cleaner does not use vacuum, it is more difficult to suck moisture, and even foreign matter that is basically to be removed may remain on the floor and the utilization of the wet vacuum cleaner may be extremely reduced have. On the other hand, when the scrubber is used, it is possible to minimize the above problems, but since the cleaning range is narrow and the cleaning part is located at the lower part of the cleaner, as is the case with the ordinary wet type moving cleaner, And clean cleaning work can be difficult.

In the case of the above-mentioned dry type moving cleaner, foreign matter existing on the floor is pushed in the moving direction of the cleaner, and at the same time, foreign matter is buried in the bottom of the mop by oil components buried in the bottom of the mop, Because there is a limit to the amount of foreign matter, if there is a lot of foreign matter on the floor, the foreign matter falls out of both ends of the rag, and eventually the foreign matter remains except for the place where the cleaner has passed. If the mop which is not buried with oil or the like is used, the efficiency is lowered further, and there is a possibility that foreign matter may remain in the place where the vacuum cleaner passes. In addition, unlike a foreign matter that is simply removed, it is difficult to remove it by a dry-type moving cleaner that does not use moisture when it is hard to remove by a movement of a mop or when it is solid foreign matter. In addition, when an obstacle such as a floor with a bend or a jaw is located at the front, it can pass through the wheel of the vacuum cleaner, but the mop fixed to the vacuum cleaner can not pass through the obstacle, , Even if exceeding, there is no buffering function, and the vacuum cleaner may be defective.

1, the cleaning system of the lower part is the same as that of FIG. 1, and the lower-cost walking-type cleaning machine, which allows the cleaning worker to work while walking, Cleaners are also being used.

The object of the present invention is to provide a wet-type mobile cleaner that combines the wet cleaner and the dry cleaner method to make it easier to remove foreign matter on the cleaning surface.

Another object of the present invention is to provide a wet-type mobile cleaner provided with a shock absorber capable of buffering action, facilitating passage of an obstacle through a dry cleaning unit, and capable of folding and storing a dry cleaning unit when the cleaner is not used.

Another object of the present invention is to provide a wet-type mobile cleaner which can easily extend the length of the dry cleaning unit so as to widely remove foreign matter on the cleaning surface.

In order to achieve the above object, the present invention provides a vacuum cleaner comprising: a cleaner body having at least two wheels disposed at a lower portion thereof and capable of moving so as to remove foreign substances from the cleaned surface; A cleaner disposed at one end of the cleaner body and having a cleaning cloth attached to the cleaner surface to remove foreign substances on the cleaner surface in accordance with movement of the cleaner body; At least two shock absorbers interconnecting the cleaner body and the dry cleaner, the at least two shock absorbers being capable of moving up and down and left and right by a piston motion and a free rotation to change the position of the dry cleaner vertically and horizontally; And a wet cleaning unit located at a lower portion of the cleaner body for supplying the cleaning liquid to the cleaning surface and wiping the cleaning liquid supplied to the cleaning surface to remove foreign substances from the cleaning surface.

The wet type dry type vacuum cleaner according to the present invention can easily remove foreign matter on the cleaning surface by combining the conventional wet type vacuum cleaner and the dry type vacuum cleaner and has a buffer for mutually connecting the vacuum cleaner and the dry cleaner, It is possible to freely move up and down and left and right of the cleaner, and the dry cleaner can buffer the movement of the cleaner surface having bending or shallow obstacles more easily. When the cleaner is not used, the dry cleaner can be folded and stored The cleaner can be easily moved, and the space occupied by the cleaner can be minimized. In addition, by extending the length of the dry cleaning part easily, it is possible to remove foreign matter on the cleaning surface more widely.

And a wet cleaning unit 160 for removing the material.

The cleaner body 102 can be used without restriction as long as it has a minimum driving force enough to beautify the cleaned surface by moving the dry cleaner 120. As shown in FIG. 2, (Not shown), but it can be pushed or pulled only by the cleaning person's work force without a separate power device. As shown in FIG. 2, in the case of the vacuum cleaner body 102 which can be moved by the power unit, a seat 104, in which a cleaning business operator can sit in order to operate the vacuum cleaner, (Not shown) that can turn on or off the power, so that the operator can operate the seated cleaner.

Further, if necessary, a fitting device capable of attaching accessories such as a cleaning device for a window, as well as a broom or a mop to be used at a corner where a manual operation such as a corner is required, may be attached to one end of the cleaner body 102 (For example, 110 in FIG. 2) and other cleaning articles (e.g., a cleaning agent, a hand mop, a towel, a mini brush, etc.) A basket (not shown) or the like may be installed on the front surface of the cleaner body 102 and may be stored, for example, in the storage space 108 located behind the seat 104 and the like. In addition, a head light may be installed on the front surface of the cleaner body 102 to enable a cleaning operation even in a dark state. Meanwhile, the wheel 100 included in the cleaner body 102 needs to be installed so that the cleaner can be held without losing its balance. More than two pieces of the wheel 100 need to be installed, one at the front of the cleaner and two at the rear . When the dry cleaning unit 120 is folded and stored, the fastening unit may be installed on the front surface of the cleaner body 102 so that the dry cleaning unit 120 can be firmly fixed to the cleaner body 102. 2, a body fastening part 111 which can be engaged with a fastening part 123 formed at one end of the dry cleaning part 120 may be installed on the front surface of the cleaner body 102 have.

3 is a perspective view of a dry cleaning part (brush) used in a wet-type dry cleaning machine according to the present invention. As shown in FIG. 3, the dry cleaning unit 120 includes a cleaning cloth 122 located on a lower surface (not shown) and at an edge thereof for attaching and removing foreign substances on a cleaning surface, Both ends 125 are inserted into the inside of the support lid 124 to prevent separation from the cleaning lid 122 and can be used for various lengths of washing cloths, And at least two support plates (128), which are located at one end, preferably a central portion, of the support bar (126) and which are movable left and right on the support bar (126) A brush connector 130 is formed at one end of the plate 128 to engage with a shock absorber (140 in FIG. 2) that mediates interconnection between the cleaner body (102 in FIG. 2) and the dry cleaning part 120, The distance between the connectors is determined by the distance Depending is varied. As described above, when the dry cleaning unit 120 is folded and stored, the dry cleaning unit 120 may be fixed to the body fastening unit (111 of FIG. 2) of the cleaner body (102 of FIG. 2) A brush coupling part 123 such as a ring may be installed at one end of the dry cleaning part 120.

The cleaning cloth 122 can be used as long as it can be removed by adhering foreign materials on the cleaning surface. The cleaning cloth 122 may be coated with an oil component such as wax to improve the adhesion with the foreign material, It is possible to minimize the amount of foreign matter escaping to both sides of the cleaning cloth 122. On the other hand, if necessary, the front surface of the cleaning cloth 122 is cleaned by absorbing a cleaning liquid (soap liquid, water, etc.), and rubber and fibers (dry fabric, nonwoven fabric, etc.) A wet cleaning method for removing the cleaning liquid and foreign matter is also possible.

Both ends 125 of the support bar 126 are inserted into the support lid 124 so that the length of the support bar 126 does not become separate from the wash lid 122, As long as it can be extended, it can be used without limitation. As shown in FIG. 3, it can be used as a thin skeleton structure, but it can also be used as a flat plate. The length of the support bar 126 can be varied in the longitudinal direction (direction perpendicular to the direction in which the cleaner advances), thereby replacing the wash hopper with the length of the support bar 126, It is possible to increase or decrease the amount of foreign substances on the cleaning surface that can be removed once (the number of times the cleaner is driven), and also to use it flexibly in accordance with the passage interval of the cleaning work space.

4 is a view showing a state in which the support bar included in the dry cleaning unit of the present invention is expanded (A) or reduced (B). As a method of varying the length of the support bar 126, there is a method similar to a principle in which a normal antenna is expanded or contracted. When such a method is used, a method of extending the length of the support bar 126 As shown in Fig. 4, in a state in which the support bar 126 is in a contracted state (Fig. 4A), the both end support bars 126d and 126e are pulled out to press the middle support bars 126b and 126c The other intermediate support bars 126b and 126c which are partially hidden inside the center support bar 126a are extended to the outside so that the other end support bars 126d and 126e which are partially hidden inside thereof are extended outwardly. And eventually becomes an expanded form as shown in FIG. 4B. In a state where the support bar 126 is extended (FIG. 4B), the support bars 126d and 126e are supported by the center support bars 126a A part of the middle support bars 126b and 126c is concealed inside the center support bar 126a and a part of both end support bars 126d and 126e is held in the middle support bar 126a, Is concealed in the inner portions 126b and 126c, thereby becoming a reduced shape as shown in Fig. 4A.

Next, each of the support plates 128 is provided with two or more shock absorbers (140 in FIG. 2) which mediate the interconnection of the cleaner body (102 in FIG. 2) and the dry cleaner 120 The distance (d in FIG. 3) between the brush connectors 130 must also be varied so that the center of gravity of the brush connector 130 is varied according to the length of the variable support bar 126.

3, the brush connector 130 may be formed on each of the two separated support plates 128, and the distance between the two separated support plates 128 may be adjusted, The distance between the connectors 130 (d in Fig. 3) can be expanded or contracted, so that the center of gravity can be aligned. 4, the center support bar 126a, the intermediate support bar 126a, the middle support bar 126a, the middle support bar 126a, 126b, 126c, or both end support bars 126d, 126e. However, in order to align the center of gravity, the separated support plates 128 may be provided together with the center support bars 126a, or the intermediate support bars 126b positioned on both sides of the center support bars 126a And 126c of the intermediate support bars 126b and 126c or separately on the respective end support bars 126d and 126e located outside the intermediate support bars 126b and 126c. In addition, a method of installing a rail between the brush connectors 130 (in the longitudinal direction of the dry cleaning unit 120) and adjusting the distance between the brush connectors 130, ) Can be varied in various ways.

FIG. 5 is a perspective view of a shock absorber used in a wet-type moving cleaner according to the present invention. FIG. 5, the shock absorber 140 is a type of shock absorber (shock absorber) used as a part of an automobile or the like. The shock absorber 140 includes a cylinder 142 filled with oil or gas, A piston 144 having a length f when the piston 142 is exposed to the outside is expanded or contracted by reciprocating the inside and outside of the cylinder 142 and a piston 142 having one end of each of the cylinder 142 and the piston 144 The cylinder connector 146 and the piston connector 148 and the one end 150a are coupled to the cylinder connector 146 so as to be movable up and down while the other end 150b is connected to the dry cleaner 120 The brush connector 150 and one end 152a of the brush connector 150 are coupled to the piston connector 148 so as to freely rotate. And a cleaner body engaging portion 152 coupled to the body (102 of FIG. 2) .

As described above, the shock absorber 140 has a structure capable of adjusting the length or angle in three ways. In the wet-type moving cleaner according to the present invention, the shock absorber 140 has two or more Should be included. FIG. 6 is a side view showing a state (A) of the wet / dry mobile cleaner according to the present invention during operation and a state (B) during non-operation. With reference to Figs. 2, 3, 5 and 6, three structures capable of adjusting the length or angle and the advantages thereof will be described.

The shock absorber 140 extending from the piston connector 148 to the brush engagement portion 150 is connected to the suction port 152 of the cleaner body 152 by the first end 152a of the cleaner body coupling portion 152 and the piston connector 148, The dry cleaning part 120 coupled to the other end of the shock absorber 140 is also capable of moving freely in the vertical direction and the left and right direction with the body coupling part 152 as an axis, It becomes possible. This movement is possible because one end 152a of the cleaner body coupling part 152 is inserted into the piston connector 148 and the piston connector 148 is inserted into one end of the cleaner body coupling part 152 152a on the outer circumferential surface. For example, it is the same as the principle of sweeping all the outer surfaces of a fist with the palm of a hand while wrapping a fisted hand of a person with the palm of another hand. One end 150a of the brush coupler 150 is coupled to the cylinder connector 146 to move up and down and the dry cleaner 120 coupled to the other end 150b of the brush coupler 150 ) Can be made flexible. Thirdly, the piston 144 of the shock absorber 140 performs a piston movement reciprocating inward / outward of the cylinder 142, so that the length of the shock absorber 140 itself can be expanded or reduced.

The position of the dry cleaning unit 120 can be moved (changed) or positioned in various forms such as up, down, right, and left by using three systems that can adjust the length or angle of the buffer 140. First, the dry cleaning unit 120 connected to the buffer 140 can be moved (changed) to the left or right. In this case, the cleaner body 102 can be easily cleaned Work becomes possible.

In addition, when the dry cleaning unit 120 is moved up and down from the cleaned surface, it is possible to cope with obstacles of various heights located in front of the cleaner. In addition, Can be made easier. Above all, when the cleaning operation is not performed, the area occupied by the cleaner can be minimized, and the dry cleaning unit 120 can be folded and stored for aesthetic appeal. 6, the length of the shock absorber 140 itself is shortened to be as short as possible, the dry cleaner 120 is rotated to the upper portion of the shock absorber 140, and then the cleaner body 102 is rotated, So that the dry cleaning unit 120 and the shock absorber 140 are lifted. At this time, the brush fastening part 123 located at one end of the dry cleaning part 120 is coupled with the body fastening part 111 located on the front surface of the cleaner body 102 so that the dry cleaning part 120 is fixed. .

6B, when the dry cleaning unit 120 is rotated to the upper portion of the buffer 140, the lower surface 121 of the dry cleaning unit 120 faces the cleaner body 102 This is not only cosmetic but also for alleviating the foreign substance falling on the lower surface 121 of the dry cleaning part 120 from falling to the floor. 5, the dry cleaning unit 120 may be rotated to move to the upper portion of the buffer 140. The brush cleaning unit 150 150b are screwed to the brush connector (130 in Fig. 3) (one pair), they can be rotated by simple manipulation using a part of the body without the need for a large force.

In addition, by maximizing the buffering force by the three factors that can control the length or angle of the buffer 140, it is possible to move the flexible vacuum cleaner even on a clean surface with bending or obstacle during the cleaning operation. As described above, the wet-type moving cleaner according to the present invention can be advantageously used by using three elements capable of adjusting the length or angle of the buffer 140 in place.

2) of the cleaner body 102 (see FIG. 2), preferably the cleaner body 102 (see FIG. 2), which is included in the wet-type moving cleaner according to the present invention, And can be installed in the center of the lower part. The wet cleaning unit (160 in FIG. 2) is a conventional wet cleaner, which is used to clean the cleaning liquid supplied to the cleaning surface after the cleaning liquid is supplied to the cleaning surface, and a vacuum, Or a wet apparatus such as a scrubber (cleaning and dust collecting apparatus) may be used. 2), the efficiency of the cleaning operation can be improved compared with the case of using only the dry cleaning unit 120 (see FIG. 2). For example, when the dry cleaning unit 120 It is possible to remove foreign matter which may remain in the passing place.

In addition, a rubber blade (not shown) for removing water and foreign matter which may remain without being removed is provided on the lower portion of the wet-type mobile cleaner according to the present invention, preferably, And its length (lateral direction) should be similar to or slightly longer than the width of the cleaner at the location of the rubber blades. In addition, it is preferable that the rubber blade is moved up and down so as to be separated from the cleaning surface by a predetermined distance so that the cleaning device can be easily moved when the cleaning operation is unnecessary.
