Meanwhile, in the illustrated embodiment, the crank 230 is rotatably coupled to the crank mounting part 240 fixed to the slider 250, but the crank 230 is directly connected to the slider 250. It can also be configured to be combined.
That is, when the crank mounting part 240 is integrally formed to form part of the slider 250, the crank 230 may be directly coupled to the slider 250.
The pair of arm portions 254 extend horizontally to the side of the slider 250 so as to be symmetrical to each other. The pair of arm portions 254 extend in left and right directions, respectively, and are vertically bent to form parallel to each other.
At the ends of the pair of arm portions 254, protrusions 256 are projected downward, respectively.
The arm 254 may be formed in another shape instead of the illustrated shape. In other words, if it extends from the slider 250 to the position of the protrusion 256 and does not interfere with other components, it may be formed in another form such as a straight line or a curve.
The protrusion 256 is inserted into the fastening groove 115 formed in the mop mounting plate 100. The structure of the mop mounting plate 100 including the fastening groove 115 will be described in detail later.
Meanwhile, in the illustrated embodiment, a pair is provided so that the arm portions 254 of the slider 250 are symmetrical to each other, but only one arm portion may be formed as long as it can be combined with the mop mounting plate. However, in the exemplary embodiment in which the arm part 254 and the protrusion part 256 are provided in two, the mop mounting plate may be more firmly fastened than when only one is formed, and the rotation of the mop mounting plate may be prevented.
The drive device 200 preferably further includes a guide rail 260 for guiding the reciprocating motion of the slider 250.
The guide rail 260 is mounted to the rail mounting portion 36 formed at the bottom of the lower case 30.

As shown in FIG. 5, the mop mounting plate 100 may be formed as a single plate, but the bottom plate 120 to which the mop 300 is attached to the bottom surface is coupled to the protrusion 256 at an upper side thereof. It may be made of an upper plate 140 in which the groove 115 is formed.
The fastening groove 115 of the mop mounting plate 100 is preferably provided with a hook member 150.
In detail, the lower plate 120 has a groove in which the hook member 150 is seated.
A pair of holes is formed in the upper plate 140 to form the fastening groove 115. When the lower plate 120 and the upper plate 140 are combined, the end of the hook member 150 is inserted into the fastening groove 115.
As shown in FIG. 6, the hook member 150 includes a rectangular hook plate 152 and a pair of hook portions 154 protruding from both ends of the hook plate 152. The hook member 150 is mounted in the fastening groove 115 of the mop mounting plate 100, but in FIG. 6, the mop mounting plate 100 is omitted for convenience and only the hook member 150 is illustrated.
The pair of hook portions 154 are bent convexly in a direction facing each other. In addition, the pair of hook portions 154 are formed to be elastically open.
The pair of protrusions 256 of the slider 250 protrudes further below the lower surface of the lower case 30 through the pair of slots 270 formed at the bottom of the lower case 30.
At the protruding end of the protrusion 256, a hook fastening groove 258 is formed to selectively insert a portion of the hook portion 154 in front and rear sides thereof.
The hook fastening groove 258 is shown in the form of a hole penetrating back and forth, it may be formed in a groove shape to be coupled to a portion of the hook portion 154.
When mounting the mop mounting plate 100, a pair of hook portion 154 of the hook member 150 is elastically open along the side of the protrusion 256, the hook fastening of the protrusion 256 A groove 258 is reached.
When the hook part 154 reaches the hook fastening groove 258, the inner portions of the pair of hook parts 154 that are opened are elastically entered and hooked into the hook fastening groove 258. As a result, the mop mounting plate 100 and the driving device 200 are coupled to each other.
When detaching the hook member 150 from the protrusion 256, it can be separated by pulling the mop mounting plate 100 as opposed to when engaged.
That is, when the rag mounting plate 100 is pulled out, the pair of hook portions 154 of the hook member 150 are separated from each other and come out of the hook fastening groove 258. Subsequently, when the mop mounting plate 100 is continuously pulled out, the pair of hook portions 154 that are in contact with the side surface of the protrusion part 256 are completely separated, thereby separating the mop mounting plate 100.

The mop mounting plate 100A of the illustrated embodiment includes two or more frame parts 170 on which the fastening grooves 115 are formed, and two or more mops 300 are wound between the pair of frame parts. It comprises a shaft 180.
The pair of frame portions 170 are formed such that the rectangular plates symmetrically spaced apart from each other by a distance corresponding to the width of the mop 300.
A pair of shaft portions 180 are connected between the two frame portions 170 so that the mop 300 is wound around the pair of shaft portions 180.
The pair of shaft portions 180 may be fixedly connected to the pair of frame portions 170, or may be rotatably connected. That is, when the two shaft portions 180 are rotatable, the mop 300 wound around the shaft portion 180 may be rotated.
Of course, even if the two shaft portions 180 are fixed, the user can move the cleaning surface of the mop by rotating the mop 300 by hand. However, if the two shaft portion 180 is rotatable, while the mop 300 rotates during cleaning, the bottom surface may be cleaned with a cleaner surface.
In addition, the two shaft portion 180 may be configured to rotate only in one direction by having a ratchet device at one end. Since the mop mounting part 100 and the mop 300 mounted thereto have a linear reciprocating motion, the shaft part 180 is more preferably rotated in only one direction.
The mop 300 used in the present embodiment may have a circular band shape to be mounted on the shaft 180. In addition, after winding the band-shaped mop to the shaft portion 180, it is also possible to combine both ends of the mop with each other.
