Description:
CROSS REFERENCE TO RELATED APPLICATION(S 
     This application is a continuation application, claiming priority under §365(c), of an International Application No. PCT/KR2021/007213, filed on Jun. 9, 2021, which is based on and claims the benefit of a Korean Patent Application No. 10-2020-0096768, filed on Aug. 3, 2020, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. 
    
    
     BACKGROUND 
       1 . Field 
     The disclosure relates to a floorcloth washer. More particularly, the disclosure relates to a washing device for washing a floorcloth used in a mop cleaner and a cleaning system including the same. 
       2 . Description of Related Art 
     A mop cleaner is generally used by attaching a wet mop to the bottom of a cleaner body. 
     Recently, various types of mop cleaners have been developed and distributed by emphasizing the convenience of use. In particular, a rotary mop cleaner which is configured to rotate the mop coupled to the bottom surface of the main body by a motor is popular in the market. 
     The rotary mop cleaner generally includes a main housing, an operation support coupled to the main housing to move the main housing, and a rotating plate rotatably coupled to the bottom surface of the main housing. The wet mop is attached to the rotating plate in a detachable manner. 
     Usually, the bottom surface of the rotating plate is generally configured with Velcro so that the wet mop may be attached. The wet mop has a disk shape similar to the rotating plate. One side of the wet mop is made of a fabric material to clean the floor, and the other side is made of a material so that the mop can be attached to the Velcro of the rotating plate. 
     The mop cleaner described above has the inconvenience of having to use the wet mop by replacing it or using it again after washing the wet mop when it becomes dirty. 
     For example, after cleaning is completed, the user must remove the wet mop and perform a separate washing action to clean the contaminated wet mop. In this case, because the user removes, washes, and squeeze the contaminated wet mop by hand, the user may face cumbersome and hygienic problems. 
     The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

       FIG.  11    is a view illustrating a floorcloth of a mop cleaner mounted to a floorcloth washer according to an embodiment of the disclosure. 
       FIG.  12    is a view illustrating a floorcloth placed in a cleaning station of a floorcloth washer according to an embodiment of the disclosure. 
     Referring to  FIGS.  11  and  12   , the process of washing, spin-drying and drying the floorcloth of the floorcloth washer  100  of the disclosure is briefly described as follows. 
     In order to wash the floorcloth  10  of the mop cleaner  1   a , the cover  120  of the floorcloth washer  100  is opened and the floorcloth  10  of the mop cleaner  1   a  is placed on the cleaning station  150 . 
     The washed floorcloth  10  is removed from the cover  120  of the floorcloth washer  100 . 
     In order to separate the floorcloth  10  from the mop cleaner  1   a , the guide rib  115  provided in the body  110  of the floorcloth washer  100  may be used. Because the guide rib  115  interferes with the floorcloth coupler  3  to which the floorcloth  10  is mounted, the floorcloth coupler  3  may be separated from the body  2  of the mop cleaner  1   a . 
     When the floorcloth  10  and the floorcloth coupler  3  are accommodated in the cleaning station  150 , the cover  120  is closed. As the cover  120  is closed, the rotating connector  260  of the cover  120  and the floorcloth coupler  3  are connected. 
     Because the rotating connector  260  is connected to the driving device  200 , the floorcloth coupler  3  connected to the rotating connector  260  may be rotatably provided. 
     A washing mode of the floorcloth washer  100  proceeds when the power button  123  of the cover  120  is pressed by the user. When the power button  123  is pressed, the water supply valve  132  is operated by the controller  250  and water is supplied to the cleaning station  150  for a pre-determined time or in a pre-determined amount from the water tank  131  of the water supplier  130 . 
     When water is supplied to the cleaning station  150 , the motor  210  of the driving device  200  may rotate in a first direction CC and a second direction CCW, respectively. 
     The first motor shaft  211   a  and the second motor shaft  211   b  of the motor  210  may be respectively connected to the rotating connector  260 . Therefore, the floorcloth  10  connected to the rotating connector  260  may rotate in the first direction CC and the second direction CCW, respectively. The rotational load of the motor  210  may be appropriate within approximately 200 to 250 RPM. 
     The floorcloth  10  rotated in the first direction CC and the second direction CCW by the motor  210  may come into contact with the cleaning plate  151  and rub against the cleaning protrusion  152 . Accordingly, the floorcloth  10  is washed. 
     When a predetermined time or a predetermined number of rotations is completed, the drain valve  144  of the water drainage  140  may be opened. When the water of the cleaning station  150  completely drains out into the drain tank  141 , the drain valve  144  may be closed. 
     When the drain valve  144  is closed, water may be supplied from the water tank  131  and the motor  210  may operate to rotate the floorcloth  10  again. This cycle may be repeated 2 to 3 times in total. 
     When the washing mode is completed, the spin-drying mode may proceed with the drain valve  144  open. 
     The spin-drying mode may be performed by rotating the floorcloth  10  as the motor  210  is rotated by the controller  250 . In this case, the water supply valve  132  is closed to prevent water supply. 
     When the spin-drying is completed, the controller  250  may operate the fan  240  to supply air to the cleaning station  150 . The floorcloth  10  may be dried by the air supplied to the cleaning station  150 . 
     In a drying mode, the fan  240  and the motor  210  may be simultaneously driven. In the drying mode, the fan  240  may be driven to dry the floorcloth  10  while the floorcloth  10  is being rotated. 
     When washing, spin-drying and drying are completed, the user can open the cover  120  and remove the washed floorcloth  10 . 
     As mentioned above, the user can automatically perform washing, spin-drying, and drying of the floorcloth  10  by the floorcloth washer  100 . Therefore, the user’s convenience can be improved. 
     Because washing and drying may be performed at once, it may be possible to quickly reuse the floorcloth. In addition, because, without directly touching the contaminated floorcloth by hand, the user separates and combines the floorcloth from and to the mop cleaner  1   a , hygiene and convenience can be improved. 
     While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those of skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
