     BACKGROUND 
     The present disclosure relates to a cleaner holder. 
     A cleaner is a device that performs cleaning by sucking and wiping dust or foreign substances on a surface to be cleaned. 
     Such a cleaner may be classified into a manual cleaner that performs cleaning while a user directly moves the cleaner and an automatic cleaner that performs cleaning while the cleaner is driven by itself. The manual cleaner may be classified into a canister cleaner, an upright cleaner, a handheld cleaner, a stick cleaner and the like depending on types of the cleaner. 
     The above-described cleaner may have a rechargeable battery embedded therein, and the rechargeable battery may supply electric power for operating the cleaner only when being frequently charged. Thus, the cleaner requires a holder that may simultaneously charge the rechargeable battery and hold the cleaner. 
     Contents of a vacuum cleaner holder are disclosed in Korean Patent Application Publication No. 10-2012-0103956 as the prior art. 
     The vacuum cleaner holder according to the prior art includes a pedestal for holding a head of a vacuum cleaner to simultaneously charge and hold the vacuum cleaner and a support having charging pins for charging the vacuum cleaner. 
     Meanwhile, the vacuum cleaner holder according to the prior art, which holds a vacuum cleaner having a center on a lower side thereof, is inserted into support pieces on a lower side of the vacuum cleaner to support the vacuum cleaner. However, in case of a cleaner having a center on an upper side thereof, because a charging terminal should be provided on an upper side, the cleaner holder according to the prior art may not hold the cleaner. 
     Meanwhile, the vacuum cleaner holder according to the prior art may charge a cleaner body but may not separately charge a battery. Thus, because the cleaner body should be charged again when the battery provided in the cleaner body is discharged during cleaning, user&#39;s inconvenience may be caused. 
     SUMMARY

     The electric wire  114  may extend to an inside of the base  210  through an upper end of the base  210  and may extend to an outside of the base  210  through a side surface or a bottom surface of the base  210  again. 
     A cord reel (not illustrated) on which the electric wire  114  is wound may be provided in the base  210 . In detail, the cord reel may be provided inside the base  210 . Thus, the user may adjust an extending length of the electric wire  114  as needed. 
     The base  210  may include an inclined surface  213  on which the suction nozzle  340  of the cleaner  300  is held and a stopper  215  for preventing the suction nozzle  340  of the cleaner  300  from being separated therefrom. 
     The stopper  215  may protrude from an end of the inclined surface  213 . The stopper  215  serves to support the suction nozzle  340  such that a state in which the suction nozzle  340  is stably seated on the base  210  may be maintained. In some cases, the weight of the cleaner  300  may be supported by the cleaner guide  137  as well as a portion of the base  210 , such as the stopper  215 . That is, the weight of the cleaner  300  may be transferred to the stand  200  via both the charging stand body  100 , which supports the cleaner body  310 , and the base  210 , which supports the suction nozzle  340 . In some cases, when the cleaner  300  is coupled to the charging stand body  100  and supported by the stand  200 , as seen for example in  FIG. 5 , the highest point of the charging stand body  100  may be positioned vertically higher than the highest point of the cleaner  300 . 
     Meanwhile, a dust collector (not illustrated) may be provided in the first body  110 . The dust collector may communicate with the dust container  315  provided in the cleaner body  310 . Dust collected in the dust container  315  may be moved to the dust collector by suction force generated by a suction motor of the cleaner body  310  or suction force generated by a separate device provided in the dust collector. Because the dust collected in the dust container  315  does not need to be directly emptied due to the dust collector, user&#39;s convenience may be improved. 
     A spaced member (not illustrated) for maintaining a predetermined distance between the first body  110  and the wall surface may be provided on the rear surface  111  of the first body  110 . The spaced member may extend rearward from the rear surface  111  of the first body  110 .

     In detail, when the locking part  120  is operated, the locking part  120  may be rotated forward (in a counterclockwise direction in  FIG. 6B ) to be coupled to the outer peripheral surface of the battery housing  320 . Accordingly, the locking part  120  may cover at least a portion of the battery housing  320 . 
     When the locking part  120  is rotated forward, the elastic member (not illustrated) may apply elastic force such that a state in which the locking part  120  is rotated forward is maintained. Accordingly, the locking part  120  may serve to fix the battery housing  320  to the first body  110 . 
       FIG. 7  is a view illustrating a state in which the extra battery is separated from the cleaner holder,  FIG. 8  is a perspective view illustrating the extra battery of  FIG. 7 ,  FIG. 9  is a view illustrating a bottom surface of the extra battery of  FIG. 7 , and  FIG. 10  is a side view illustrating the extra battery of  FIG. 7 . 
     Referring to  FIGS. 7 to 10 , a battery accommodating space  130   a  for accommodating the extra battery  302  is formed in the second body  130 . A battery guide  136  for guiding insertion or withdrawal of the extra battery  302  may be provided in the battery accommodating space  130   a.    
     The extra battery  302  may include a battery cell that is not illustrated and a frame  3021  configured to protect the battery cell. 
     The frame  3021  may have a rectangular shape, as illustrated. In detail, the frame  3021  may have a shape extending in a front-rear direction. However, the present disclosure is not limited thereto. 
     A protrusion part  3022  may be formed on a bottom surface of the frame  3021  and terminal holes  3023  through which the second charging port  131 , which will be described below, passes may be formed in the protrusion part  3022 . The second charging port  131  is provided in the battery accommodating space  130   a.  A battery terminal that is in contact with the second charging port  131  may be provided inside the terminal holes  3023 . 
     The terminal holes  3023  are formed on a bottom surface of the protrusion part  3022 . Thus, while the extra battery  302  is downward inserted into the battery accommodating space  130   a,  the second charging port  131  may pass through the terminal holes  3023  to come into contact with the battery terminal. 
     The battery guide  136  serves to guide downward movement of the protrusion part  3022  such that the second charging port  131  may be stably inserted into the terminal holes  3023 . 
     Here, the protrusion part  3022  may be located to be biased toward one side from a center of the bottom surface of the frame  3021  such that the user may easily identify a direction in which the extra battery  302  is inserted into the battery accommodating space  130   a.    
     The extra battery  302  may further include a plurality of coupling parts  3024  and  3026 . The plurality of coupling parts  3024  and  3026  may include a first coupling part  3024  arranged on one side of the frame  3021  and a second coupling part  3026  arranged on the other side of the frame  3021 . The first coupling part  3024  and the second coupling part  3026  may be located opposite to each other. 
     As an example, the first coupling part  3024  and the second coupling part  3026  may be provided in a front-rear direction of the frame  3021 . Here, when viewed from above, the first coupling part  3024  and the second coupling part  3026  may be provided on a narrow surface of the frame  3021 . 
     The first coupling part  3024  may be formed integrally with the frame  3021  and may be elastically deformed by external force. 
     The first coupling part  3024  horizontally extends from an upper surface of the frame  3021  by a predetermined length, and then extends downward. Accordingly, the first coupling part  3024  is spaced apart from an outer surface of the frame  3021 . 
     That is, a space between the frame  3021  and the first coupling part  3024  is formed. Due to the space, the first coupling part  3024  may be elastically deformed in a direction in which it becomes closer to the frame  3021 , by external force. 
     The first coupling part  3024  may include a first hook  3025 . The first hook  3025  may have a thinner thickness than other portions of the first coupling part  3024 . 
     A groove to which the first hook  3025  of the first coupling part  3024  is coupled may be formed in the battery housing  320 . Here, the first hook  3025  of the first coupling part  3024  is inserted into the groove while being introduced into the battery housing  320 . 
     The second coupling part  3026  may include a second hook  3027  rotatably coupled to the frame  3021 . 
     The second coupling part  3026  may be elastically supported by a resilient member (not illustrated) provided in the frame  3021 . The resilient member provides elastic force by which the second coupling part  3026  is moved in a direction it becomes farther away from the frame  3021 , to the second coupling part  3026 . 
     The second coupling part  3026  may be coupled to a battery coupling part (not illustrated) within the battery housing  320  in a state in which the extra battery  302  is accommodated in the battery housing  320 . 
     Meanwhile, a surface on which the first coupling part  3024  is provided may be named a first surface and a surface on which the second coupling part  3026  is provided may be named a second surface. Further, surfaces of the extra battery  302 , which intersect the first and second surfaces, may be named a third surface and a fourth surface, respectively. Thus, the first surface and the second surface may face each other, and the third surface and the fourth surface may face each other. Further, as illustrated, a horizontal length of the first surface and the second surface may be smaller than a horizontal length of the third surface and the fourth surface. 
     A step  3028  may be provided on the upper surface of the frame  3021 . The step  3028  functions to restrain an insertion depth of the extra battery  302  within the battery accommodating space  130   a.  A relative structure provided in the battery accommodating space  130   a  will be described below. 
       FIG. 11  is a view illustrating an inside of a second body of  FIG. 7 ,  FIG. 12  is a plan view illustrating the second body of  FIG. 11 ,  FIGS. 13 and 14  are longitudinal sectional views illustrating a first body of  FIG. 11 , and  FIG. 15  is a view illustrating an inner peripheral surface of a battery accommodating space. 
     Referring to  FIGS. 11 to 15 , the battery accommodating space  130   a  may be recessed downward from an upper surface of the second body  130 . Further, the battery accommodating space  130   a  may have a front-rear directional width that is larger than a left-right directional width to correspond to the shape of the extra battery  302 . Accordingly, a side surface of the second body  130  may be formed to be longer than a front surface and a rear surface of the second body  130 . That is, the second body  130  may have a rectangular shape. 
     The second charging port  131  for charging the extra battery  302  is provided inside the second body  130 . The second charging port  131  may be arranged to be lower than the first charging port  113 . The second charging port  131  may be selectively in contact with the extra battery  302  accommodated in the second body  130 . 
     A recessed part  133  in which the second charging port  131  is provided may be provided in the second body  130 . The recessed part  133  may have a shape corresponding to the shape of the protrusion part  3022  of the extra battery  302 . Further, the recessed part  133  may be located to be biased forward from a center of a bottom surface  130   b  of the battery accommodating space  130   a  such that the user may easily identify a direction in which the extra battery  302  is inserted into the battery accommodating space  130   a.    
     The recessed part  133  may be recessed downward from the bottom surface of the second body  130 . The second charging port  131  may be provided on a bottom surface of the recessed part  133  and may protrude upward from the bottom surface of the recessed part  133 . A planar surface extending from an installation surface on which the first charging port  113  are provided and a planar surface extending from an installation surface on which the second charging port  131  is provided may intersect each other. 
     A length in which the second charging port  131  protrudes upward may be smaller than a depth of the recessed part  133 . Accordingly, an upper end of the second charging port  131  may be arranged lower than the bottom surface  130   b  of the battery accommodating space  130   a.  That is, because the second charging port  131  is accommodated in the recessed part  133 , damage of the second charging port  131  by external force may be minimized. 
     Grooves  132 ,  134  and  112  for allowing the user to easily grip the extra battery  302  accommodated in the battery accommodating space  130   a  may be formed on one side of the battery accommodating space  130   a.  The user may grip a lateral side of the extra battery  302  through the grooves  132 ,  134  and  112 . The grooves  132 ,  134  and  112  may include a first groove  132  provided in front of the battery accommodating space  130   a  and a second groove  134  and a third groove  112  provided on a rear side of the battery accommodating space  130   a.    
     The first groove  132  may have a shape that is cut downward from an upper end of a front surface of the second body  130 . Further, the first groove  132  may have a shape corresponding to a bottom surface of the first coupling part  3024  and may have a shape similar to, for example, the “U” shape. 
     The second groove  134  may have a shape that is cut downward from an upper end of a rear surface of the second body  130 . Thus, the second groove  134  is connected to the battery accommodating space  130   a.  Further, the second groove  134  may be arranged to face the first groove  132 . 
     The third groove  112  is recessed such that a finger of the user is inserted into the third groove  112  to come into contact with the second coupling part  134 . In detail, the third groove  112  may be provided in the first body  110  and may be recessed rearward from the first body  110 . Further, the third groove  112  may extend upward and downward to at least partially overlap the battery accommodating space  130   a.  Further, the third groove  112  may be connected to the second groove  134 . Thus, the second groove  134  may connect the third groove  112  and the battery accommodating space  130   a  to each other. As illustrated, the third groove  112  may constitute one groove together with the second groove  134 . 
     The first coupling part  3024  of the extra battery  302  may be accommodated in the first groove  132 , and the second coupling part  3026  of the extra battery  302  may be accommodated in the second groove  134 . In addition, the first groove  132  may support a lower side of the first coupling part  3024  and the second groove  134  may support a lower side of the second coupling part  3026 . 
     An auxiliary groove  132   a  in which the first hook  3025  is accommodated may be formed on an inner peripheral surface of the battery accommodating space  130   a.  The auxiliary groove  132   a  may be provided below the first groove  132  and may be recessed in the inner peripheral surface of the battery accommodating space  130   a.  The auxiliary groove  132   a  may be provided in the battery guide  136 . An upper end of the auxiliary groove  132   a  may be connected to the first groove  132 . 
     Unlike a case where the extra battery  302  is inserted into the battery housing  320  provided in the cleaner  300 , when the extra battery  302  is inserted into the battery accommodating space  130   a,  the first coupling part  3024  and the second coupling part  3026  are not compressed by the inner peripheral surface of the battery accommodating space  130   a.  Accordingly, the user may easily withdraw or insert the extra battery  302  from or into the battery accommodating space  130   a.    
     The second body  130  may further include a display unit  135  for displaying a residual amount of the extra battery  302 . Unlike the one illustrated, the display unit  135  may be provided in the first body  110 . 
     The display unit  135  may include a light emitting diode (LED) light that may display various colors. As an example, the display unit  135  may display the residual amount of the extra battery  302  in three stages. In detail, the display unit  135  may divide the residual amount of the extra battery  302  into upper, middle and lower parts, and may display different colors depending on the stages. Further, the display unit  135  may notify the user of the charging state as the display unit  135  flickers during charging of the extra battery  302 . 
     The battery guide  136  for guiding the extra battery  302  may be provided below the cleaner guide  137  and may extend downward. 
     The battery guide  136  may have a shape corresponding to the extra battery  302 . Accordingly, a location of a terminal of the extra battery  302  inserted into the second body  130  may be accurately aligned with the location of the second charging port  131 . Although not illustrated, a boss or groove for effectively guiding the insertion or the withdrawal of the extra battery  302  may be formed in the battery guide  136 . 
     An entrance  138  through which the extra battery  302  is introduced/withdrawn may be provided in the battery guide  136 . The entrance  138  may be provided on the battery guide  136  and may extend upward to have a predetermined height. Accordingly, an upper end of the entrance  138  may be arranged higher than an upper end of the extra battery  302  accommodated in the battery accommodating space  130   a.    
     An inner peripheral surface of the entrance  138  may be stepped to the battery guide  136  to facilitate the insertion of the extra battery  302 . In detail, the inner peripheral surface of the entrance  138  may be wider than an inner peripheral surface of the battery guide  136 . Accordingly, a seating part  1382  may be formed at a boundary between the entrance  138  and the battery guide  136  and the step  3028  of the extra battery  302  may be seated on the seating part  1382 . 
     In this way, because the battery guide  136  has a shape corresponding to the extra battery  302 , it is difficult to directly insert the extra battery  302 . However, as the entrance  138  has a wider width than the battery guide  136 , the extra battery  302  may be easily inserted. 
     A drainage hole  139  may be provided in the second body  130 . The drainage hole  139  may be formed on a bottom surface of the second body  130  to communicate with an external space. The drainage hole  139  is for preventing liquid, such as water, introduced into the second body  130  from being collected inside the second body  130 . Accordingly, the the second charging port  131  may be prevented from being damaged by the liquid such as water. 
     The drainage hole  139  may be provided in the recessed part  133  and may be arranged adjacent to the second charging port  131 . Accordingly, the liquid such as water, which is collected near the second charging port  131 , may be directly discharged. Further, the drainage hole  139  may be plural, unlike the one illustrated. 
       FIGS. 16 and 17  are longitudinal sectional views illustrating a state in which the extra battery is accommodated in the battery accommodating space of the second body. 
     Referring to  FIGS. 16 and 17 , when the extra battery  302  is inserted into the battery accommodating space  130 , the first coupling part  3024  of the extra battery  302  is seated on the first groove  132 . Thus, the user may come into contact with the first coupling part  3024  of the extra battery  302 , which is exposed through the first groove  132 . 
     The second coupling part  3026  of the extra battery  302  is seated on a bottom surface  134   a  of the second groove  134 . 
     Meanwhile, the bottom surface  134   a  of the second groove  134  and a bottom surface  112   a  of the third groove  112  are connected to each other to define a planar surface. Accordingly, at least a portion of the second coupling part  3026  may be in contact with the bottom surface  112   a  of the third groove  112 . 
     When the second coupling part  3026  of the extra battery  302  is seated on the bottom surface  134   a  of the second groove  134 , a side surface of the second coupling part  3026  is spaced apart from a side surface  112   b  of the third groove  112 . Thus, the user may come into contact with the second coupling part  3026  by inserting a finger into a spaced space between the second coupling part  3026  and the side surface  112   b  of the third groove  112 . 
     Accordingly, the user may easily insert or withdraw the extra battery  302  into or from the battery accommodating space  130   a  while gripping the extra battery  302 . 
     When the extra battery  302  is inserted into the battery accommodating space  130   a,  the second charging port  131  passes through the terminal holes  3023 . A battery terminal  3029  that is in contact with the second charging port  131  having passed through the terminal holes  3023  may be provided inside the protrusion part  3022 . Accordingly, the extra battery  302  may be charged through the second charging port  131 . 
     Because the first coupling part  3024  and the second coupling part  3026  of the extra battery  302  are not pressed by the inner peripheral surface of the battery accommodating space  130   a,  the user may easily insert or withdraw the extra battery  302  into or from the battery accommodating space  130   a.    
       FIG. 18  is a view illustrating a state in which a nozzle is separated from a charging stand body. 
     Referring to  FIG. 18 , the first body  110  may include connectors  118   a  and  118   b  to which the extra nozzles  303  and  304  are selectively coupled. The connectors  118   a  and  118   b  may extend from one side of the first body  110 . 
     The user may attach/detach the nozzles  303  and  304  to the connectors  118   a  and  118   b  as needed. Accordingly, because the extra nozzles  303  and  304  are easily stored and used, user convenience may be improved. 
       FIG. 19  is a view illustrating a state in which the charging stand body is separated from the support, and  FIG. 20  is a view illustrating a state in which the charging stand body on which the cleaner is held is mounted on a wall surface. 
     Referring to  FIGS. 19 and 20 , the cleaning stand body  100  may include a coupling part  119  to which the support  220  is coupled. The coupling part  119  may be provided in the first body  110 . The support  220  may be detachably coupled to the coupling part  119 . Accordingly, the user may easily separate the charging stand body  100  and the support  220  from each other. 
     As needed, the user may fix the charging stand body  100  from which the support  220  is separated to a wall surface  2  using the fixing parts  115   a  and  115   b.    
       FIG. 21  is a view illustrating a state in which the charging stand body is supported by the floor. 
     Referring to  FIG. 21 , the rear surface  111  of the charging stand body  100  may be supported by the floor. To achieve this, the rear surface  111  of the charging stand body  100  may have a planar shape. 
     The cleaner  300  may be seated and held on the first body  110 , and the locking part  120  may be coupled to a lateral side of the cleaner  300  to fix the cleaner  300 . 
     In this way, because the charging stand body  100  may be held in various schemes according to a usage situation, user convenience may be improved. 
       FIG. 22  is a view illustrating a state in which the cleaner is held on the cleaner holder according to another embodiment. 
     The cleaner holder according to the present embodiment has the battery accommodating space, a location of which is different from that of the cleaner holder according to the prior embodiment, and has the other components that are substantially identical to those of the cleaner holder according to the prior embodiments. Thus, the substantially identical components are designated by the same reference numerals in the prior embodiments, and detailed descriptions thereof will be omitted. 
     Referring to  FIG. 22 , the cleaner holder according to the present embodiment is the same as the cleaner holder according to the prior embodiment in that the battery  302  is accommodated in the second body  130  and is charged in an accommodated state. 
     However, unlike the prior embodiment, the cleaner holder according to the present embodiment the battery accommodating space is recessed from a front side to a rear side. The prior embodiment is different from the present embodiment in that the battery accommodating space is recessed from an upper space toward a rear side of the second body  130 . 
     However, the present embodiment is the same as the prior embodiment in that, when the cleaner  300  is held on the cleaner holder, at least a portion of the battery  302  accommodated in the battery accommodating space is covered by the cleaner  300 . Meanwhile, when the cleaner  300  is held on the cleaner holder in a state in which the battery  302  is separated from the battery accommodating space, the cleaner  300  covers at least a portion of the battery accommodating space.
