Accordingly, the seating space  142  may be provided in a bent shape in which the seating space  142  formed to extend in the second direction B is also formed to extend in the first direction A. 
     Since the docking opening  143  is provided to be open while facing in the second direction B, the dust collecting chamber  20  may be docked onto the docking station  100  in a direction substantially perpendicular to the direction in which the long axis of the body housing  110  extends. The cleaner  10  may be provided to be docked onto the docking station  100  in the second direction B. 
     The body housing  110  may include a docking surface  111  provided at a side in which the docking opening  143  is disposed and the cleaner  10  is docked. The docking surface  111  may be provided to form one surface of the body housing  110 . The docking surface  111  may be provided to face in the second direction B, which is the direction the docking opening  143  is opened. 
     Although not shown, the docking surface  111  may be provided in various shapes as well as a flat surface or a curved surface. 
     The docking surface  111  may extend in a planar shape having a long axis extending in one direction. Since the body housing  110  is provided in a box shape extending in the first direction A, which is the upper side and lower side direction, as described above, the long axis of the docking surface  111  may extend in a direction corresponding to the first direction A. 
     The docking opening  143  and the charging part  120  may be formed on the docking surface  111 . However, the disclosure is not limited thereto, and the charging part  120  may be disposed upward of the docking surface  111 , in detail, above the docking surface  111  in the extending direction of the docking surface  111 . 
     The cleaner  10  may be docked onto the docking station  100  in a direction facing the docking surface  111  of the docking station  100 . The cleaner  10  may be provided to be docked onto the docking station  100  in the second direction B. 
     The cleaner  10  may be docked onto the docking station  100  in a direction perpendicular to a direction in which the long axis of the docking surface  111  extends in the docking station  100 . The cleaner  10  may be provided to be docked onto the docking station  100  in the second direction B that is perpendicular to the first direction A. 
     Accordingly, when the dust collecting chamber  20  is docked onto the docking station  100 , the first direction A, which is the extending direction of the long axis of the body housing  110 , and the extension axis Y of the dust collecting chamber  20  are provided to face in directions approximately perpendicular to each other. 
     That is, the extension axis Y of the dust collecting chamber  20  may be inserted into the docking opening  143  of the docking station  100  in a direction corresponding to the second direction B. Accordingly, in a state in which the cleaner  10  is docked onto the docking station  100 , the long axis X of the extension pipe  17  of the cleaner  10  may be disposed in a direction corresponding to the first direction A. This is because the long axis X of the extension pipe  17  and the extension axis Y of the dust collecting chamber  20  are provided to be perpendicular to each other. 
     When the dust collecting chamber  20  is docked in a direction that is not perpendicular to the long axis of the docking station  100 , the extension pipe  17  of the cleaner  10  may be disposed to face other directions than the first direction A, so that the cleaner  10  docked onto the docking station  100  without the extension pipe  17  being separated by the user may lower the aesthetic sense and degrade the spatial efficiency of the space around the docking station  100 . 
     In addition, since it is also difficult for a user to separate the extension pipe or the suction unit that may be coupled to the dust collection guide  15 , the usability of the docking station  100  may decrease. 
     In order to solve such a limitation, the cleaning apparatus  1  according to the embodiment of the disclosure may be provided to allow the vacuum cleaner  10  to be docked onto the docking station  100  and allow substances collected in the dust collecting chamber  20  to be automatically discharged in the docking station  100  in a state in which the extension pipe  17  or the suction unit  18  is coupled to the dust collection guide  15  of the cleaner  10 . 
     That is, the cleaning apparatus  1  may be provided to, when the cleaner  10  is docked onto the docking station  100 , arrange the direction in which the long axis X of the extension pipe  17  of the cleaner  10  faces to be in the first direction A, which is a direction in which the long axis of the docking station  100  extends. 
     The dust collecting chamber  20  may be provided with a cyclone  24  disposed therein. The dust collecting chamber  20  may be provided to collect foreign substances to a lower side  24   a  of the cyclone  24 . The dust collecting container  20  may include a first dust collecting part  20   a  that performs primarily dust collection to collect relatively large foreign substances and a second dust collecting part  20   b  that performs dust collection by the cyclone  24  to collect relatively small foreign substances. 
     Both the first dust collecting part  20   a  and the second dust collecting part  20   b  may be provided to be open to the outside when the dust collecting chamber door  21  is opened. 
     Accordingly, when the dust collecting chamber door  21  disposed at one end of the body  22  is opened, the foreign substances collected in the dust collecting chamber  20  may be easily discharged to the outside of the dust collecting chamber  20 . 
     When the cleaner  10  is docked onto the docking station  100 , at least a portion of the dust collecting chamber  20  may be provided to be inserted into the docking part  140  through the docking opening  143 . In detail, the dust collecting chamber door  21  disposed at one end of the body  22  of the dust collecting chamber  20  may be disposed in the seating area  142  provided inside the docking part  140 . 
     Therefore, when the cleaner  10  is docked onto the docking station  100 , the dust collecting chamber door  21  is opened inside the docking part  140  so that the foreign substances collected in the dust collecting chamber  20  may be discharged inside the docking station  100  without being scattered to the outside of the docking station  100 . 
     The suction flow path  141  may be connected from the docking part  140  to the collecting part  150 . The suction flow path  141  may transmit the flow of air current generated by the suction device  130  to the dust collecting chamber  20 . That is, a suction air current generated by the suction device  130  passes through the collecting part  150 , and then along the suction flow path  141  and the seating area  142 , reaches the inside of the dust collecting chamber  20 , and the suction air current causes foreign substances inside the dust collecting chamber  20  to be discharged, along a flow of the air current, from the dust collecting chamber  20  to the seating area  142 , and then via the suction flow path  141 , collected in the collecting part  150 . 
     The collecting part  150  may include a collecting part housing  151 . The collecting part housing  151  may form an inner space. The collecting part  150  may include a dust bag  152  disposed in the inner space of the collecting part  150  and collecting foreign substances introduced through the suction flow path  141 . 
     The dust bag  152  is formed of a material that transmits air while blocking foreign substances so that foreign substances introduced from the dust collecting chamber  20  into the collecting part  150  may be collected. 
     The dust bag  152  may be directly connected to the suction flow path  141 , and the dust bag  152  may be provided detachably from the collecting part  150 . 
     As shown in  FIG.  3   , body housing  110  may include a panel  158  that is coupled to the body housing  110  or docking surface  111  through coupling members  158   a  and  158   b , and is separable from the body housing  110  so that the user replaces the dust bag  152  from the outside when foreign substances are collected in the dust bag  152  by driving of the docking station  100 . The user may separate the panel  158  and open the collecting part housing  151  to separate the dust bag  152  from the collecting part  150 , and discharge the foreign substances collected by the docking station  100 . In an example embodiment the panel  158  is arranged at the front of the body housing  110  and configured to be openable to provide an opening at the front of the body housing  110  through which the dust bag  152  can be withdrawn. 
     Although not shown in the drawing, the collecting part  150  may include an additional dust collecting chamber (not shown) in addition to the dust bag  152 . The inner space of the additional dust collecting chamber (not shown) may be provided to be larger than the inner space of the dust collecting chamber  20 , and, similar to the dust collecting chamber  20 , may include a cyclone to collect fine foreign substances. 
     The suction device  130  may include a suction fan  131  and a suction device housing  132  forming an inner space in which the suction fan  131  is disposed. 
     The suction air current formed by the suction fan  131  may move from the inner space of the suction device housing  132 , passing through the collecting part  150  and the suction flow path  141 , to be finally supplied to the dust collecting chamber  20 . 
     The docking station  100  may include a flow rate changing device  160  provided to selectively change the amount of suction air current supplied to the dust collecting chamber  20 . 
     Air and foreign substances inside the dust collecting chamber  20  may be discharged to the outside through the dust collecting chamber door  21  of the dust collecting chamber  20  along the suction flow path  141 , but some of the foreign substances may be caught with inner components of the dust collecting chamber  20  and fail to be discharged to the outside. 
     For example, foreign substances, such as hair, may be caught in the inner component of the dust collecting chamber  20 , and thus without being separated out of the dust collecting chamber  20  by the suction air current generated to a lower side of the dust collecting chamber door  21 , remain inside the dust collecting chamber  20 . 
     The suction air current delivered to the inside of the dust collecting chamber  20  may be formed to face only in a direction in which the dust collecting chamber opening  23  of the dust collecting chamber  20  is opened. Accordingly, some foreign substances may have a resistance to the direction in which the suction air current is formed, and may not be separated from the dust collecting chamber  20  by the suction air current. 
     Accordingly, foreign substances inside the dust collecting chamber  20  may not be effectively removed. 
     The docking station  100  according to the embodiment of the disclosure may include the flow rate change device  160  that is provided to selectively supply the dust collecting chamber  20  with additional outside air in addition to the suction air current to solve the above-described limitation. 
     The flow rate changing device  150  may change the flow rate inside the dust collecting chamber  20  while the suction air current is being supplied to the inside of the dust collecting chamber  20  so that the air inside the dust collecting chamber  20  is being suctioned by the suction device  130 , to variously change the flow of air inside the dust collecting chamber  20 . 
     The flow rate changing device  160  may be disposed inside the body housing  110 . The flow rate changing device  160  may be disposed between the collecting part  150  and the suction device  130 . In detail, the flow rate changing device  160  may be disposed between the collecting part  150  and a flow path to which the suction device  130  is connected. 
     However, the disclosure is not limited thereto, and the flow rate changing device  160  may be provided to be disposed between the collecting part  150  and the suction flow path  141 . 
     The suction device  130 , the flow rate changing device  160 , the collecting part  150 , and the docking part  140  may all be disposed inside the body housing  110 . 
     With respect to the first direction A, the charging part  120 , the docking part  140 , the collecting part  150 , the flow rate changing device  160 , and the suction device  130  may be sequentially disposed. 
     Accordingly, the docking station  100  may be provided in a box shape extending in the upper side and lower side direction, which is the first direction A. 
     As described above, the dust collecting container  20  may include the first dust collecting part  20   a  that performs primarily dust collection to collect relatively large foreign substances and the second dust collecting part  20   b  that performs dust collection by the cyclone  24  to collect relatively small foreign substances. 
     Both the first dust collecting part  20   a  and the second dust collecting part  20   b  may be provided to be open to the outside when the dust collecting chamber door  21  is opened. In this case, when the dust collecting container door  21  is opened, both the first dust collecting part  20   a  and the second dust collecting part  20   b  may be provided to be opened to the outside. 
     The dust collecting chamber door  21  may include a coupling protrusion  21   a  provided to be coupled to the body  22  so that the dust collecting chamber  20  is maintained in a closed state and a cap portion  21   b  configured to prevent the foreign substances collected in the second dust collecting part  20   b  from being scattered to the outside when the dust collecting chamber  20  is closed. 
     The dust collecting chamber door  21  may open and close the dust collecting chamber opening  23  while rotating around a rotation shaft  21   c  disposed at one side of one end of the body  22  in which the dust collecting chamber opening  23  is formed. 
     The rotation shaft  21   c  may be disposed on one end of the body  22  at a side adjacent to the handle  14 . That is, the rotation shaft  21   c  may be disposed at a side opposite to a side in which the extension pipe  17  is disposed with respect to the extension axis Y of the dust collecting chamber  20 . 
     This is to allow the rotation shaft  21   c  to be disposed on the upper end of the dust collecting chamber  20  in the first direction A when the cleaner  10  is docked onto the docking station  100 , as will be described below. 
     The dust collecting chamber  20  may include a fixing member  25  disposed on the other side of the one end of the body  22  and supporting the coupling protrusion  21   a  to prevent the dust collecting chamber door  21  from being separated from the one end of the body  22 . 
     The fixing member  25  may be hook-coupled with the coupling protrusion  21   a  to prevent the coupling protrusion  21   a  from being separated from the body  22 . 
     The fixing member  25  may include a push portion  25   a  provided to be rotated when pressed by an external force to release the hook coupling with the coupling protrusion  21   a , and a hook portion  25   b  hook-coupled with the coupling protrusion  21   a  in association with the push portion  25   a.    
     The fixing member  25  may include an elastic member (not shown) provided to maintain the hook-coupled state of the hook portion  25   b  and the coupling protrusion  21   a  when the fixing member  25  is not pressed by the push portion  25   a.    
     The elastic member (not shown) may be provided to be biased, in a state in which the dust collecting chamber door  21  is closed, so that the hook portion  25   b  is pressed in a direction toward the coupling protrusion  21   a , causing the hook coupling of the hook portion  25   b  and the coupling protrusion  21   a  to be maintained. 
     When a force greater than the elastic force of the elastic member (not shown) is applied to the push portion  25   a , the hook portion  25   b  is rotated in association with the push portion  25   a , and the hook coupling of the hook portion  25   b  and the coupling protrusion  21   a  may be released. 
     Therefore, when an external force is applied to the push portion  25   a  in a direction opposite to the radial direction of the body  22 , the push portion  25   a  may rotate in the opposite direction to the radial direction of the body  22 , and accordingly, the hook portion  25   b  may be rotated in the radial direction of the body  22  to move in a direction away from the coupling protrusion  21   a.    
     Accordingly, the user may press the push portion  25   a  to open the dust collecting chamber  20 , and discharge the foreign substances collected in the dust collecting chamber  20  to the outside of the dust collecting chamber  20 . 
     Hereinafter, a technical feature in which the cleaner  10  is docked onto the docking station  100  for the foreign substances collected in the dust collecting chamber  20  to be discharged will be described in detail. 
       FIG.  5    is a cross-sectional perspective view of a part of a vacuum cleaner before the vacuum cleaner is docked onto a docking station in a cleaning apparatus according to an embodiment of the disclosure,  FIG.  6    is a cross-sectional perspective view of a part of a vacuum cleaner in a state in which the vacuum cleaner is docked onto a docking station in a cleaning apparatus according to an embodiment of the disclosure, and  FIG.  7    is a cross-sectional perspective view of a part of a vacuum cleaner when a suction device is driven in a state in which the vacuum cleaner is docked onto the docking station in the cleaning apparatus according to an embodiment of the disclosure. 
     As described above, the dust collecting chamber  20  may be docked onto the docking station  100  such that the extension axis Y faces in the second direction B. Accordingly, the dust collecting chamber  20  may be docked onto the docking station  100  such that the extension axis Y is arranged in a direction perpendicular to the first direction A, which is the direction of gravity. 
     When the extension axis Y of the dust collecting chamber  20  is arranged in a direction corresponding to the direction of gravity, the dust collecting chamber opening  23  may be arranged to be open downward, and the dust collecting chamber door  21  may be arranged at the lower end of the dust collecting chamber  20 . In this case, when the fixing member  25  is pressed, the dust collecting chamber door  21  may be separated from the body  22  by the gravity and rotate about the rotation shaft  21   c  in the direction of gravity, causing the dust collecting chamber opening  23  to be opened. 
     However, when the extending direction of the extension axis Y of the dust collecting chamber  20  is arranged in a direction perpendicular to the direction of gravity as in the embodiment of the disclosure, the dust collecting chamber door  21  may remain closed even when the fixing member  25  is pressed, unless an additional external force is generated. 
     In particular, since the rotation shaft  21   c  of the dust collecting chamber door  21  is disposed on a side opposite to a side in which the extension pipe  17  is disposed with respect to the extension axis Y of the dust collecting chamber  20  as described, the rotation shaft  21   c  may be provided to be disposed on the upper end of the dust collecting chamber  20  in the first direction A when the cleaner  10  is docked onto the docking station  100 , so that the dust collecting chamber door  21  may remain closed without being affected by the gravity even in an openable state. 
     That is, since the dust collecting chamber  20  is docked onto the docking station  100  such that the extension axis Y of the dust collecting chamber  20  faces in the second direction B as shown in  FIGS.  5  and  6   , the dust collecting chamber door  21  may maintain a closed state even when the fixing member  25  is pressed inside the docking part  140  in the docked state of the dust collecting chamber  20 . 
     The docking part  140  may include an opening guide  145  provided to press the push portion  25   a  when the dust collecting chamber  20  is seated in the seating space  142  through the docking opening  143  so that the dust collecting chamber door  21  is set into an openable state. 
     The opening guide  145  may be arranged on a front inner circumferential surface  144  arranged on the front side of the seating space  142  in the second direction B and forming the docking opening  143  at a position of the seating space  142  in which the docking opening  143  is connected. 
     The opening guide  145  may be formed as a partial area of the front inner circumferential surface  144  according to the embodiment of the disclosure. However, the disclosure is not limited thereto, and the opening guide  145  may be provided as a region or protruding surface protruding from the front inner circumferential surface  144  toward the center, or in the shape of a protrusion, a rib and the like protruding toward the center from the inner circumferential surface. 
     The front inner circumferential surface  144  may be provided to have a size substantially corresponding to that of an outer circumferential surface of the body  22 . In detail, the circumference of the front inner circumferential surface  144  of the docking opening  143  and the circumference of the dust collecting chamber body  22  may be provided to substantially the same. 
     That is, when the dust collecting chamber  20  is docked onto the docking station  100 , the front inner circumferential surface  144  and the outer circumferential surface of the body  22  may be provided to face each other at a predetermined distance therebetween. 
     Accordingly, as the dust collecting chamber  20  is being seated in the seating space  142  through the docking opening  143 , the dust collecting chamber  20  may have the outer circumferential surface of the body  22  moved along the front inner circumferential surface  144  in the second direction B. 
     In this case, the push portion  25   a  protruding outward from the outer circumferential surface of the body  22  may be pressed against the opening guide  145 . 
     In detail, as the dust collecting chamber  20  is moved in the second direction B, the push portion  25   a  disposed on the outside of the outer circumferential surface of the body  22  is pressed in the first direction A by the opening guide  145 , which causes the push portion  25   a  to rotate opposite to the radial direction of the outer circumferential surface of the body  22 , so that the hook coupling between the hook portion  25   b  and the coupling protrusion  21   a  is released, thereby setting the dust collecting chamber door  21  into an openable state. 
     However, as described above, the dust collecting chamber door  21  is maintained in an openable state without being opened unless an additional external force is generated. 
     The dust collecting chamber  20  may include a gasket  26  on the dust collecting chamber door  21  to seal a space between the dust collecting chamber door  21  and an inner circumferential surface  22   a  of the body  22 . The gasket  26  may be formed of an elastic material, such as rubber, to seal a space between the inner circumferential surface  22   a  of the body  22  and the dust collecting chamber door  21  to prevent foreign substances collected in the dust collecting chamber  20  from being scattered to the outside. 
     As described above, since the gasket  26  is formed of an elastic material, the gasket  26  may be biased toward the inner circumferential surface  22   a  of the body  22  when the dust collecting chamber door  21  is in a closed state. 
     That is, the gasket  26  is biased in the radial direction of the body  22  with respect to the center of the body  22 , so that when there is no external force on the dust collecting chamber door  21 , the gasket  26  may elastically support the dust collecting chamber door  21  to prevent the dust collecting chamber door  21  from being opened from the body  22 . 
     Accordingly, even when the fixing member  25  is pressed by the opening guide  145 , the dust collecting chamber door  21  is prevented from being separated from the body  22 . 
     Thereafter, as shown in  FIG.  7   , when the suction device  130  is driven and the suction air current flows into the dust collecting chamber  20  through the seating space  142 , the suction air current provides the dust collecting chamber door  21  with an external force in a direction to open the dust collecting chamber door  21  so that the dust collecting chamber door  21  is opened and the foreign substances collected in the dust collecting chamber  20  are caused to flow into the collecting part  150  through the seating space  142  and thus be collected in the collecting part  150 . 
     The seating space  142  may be provided to allow the dust collecting chamber  20  to be inserted thereinto and allow the dust collecting chamber door  21  to be rotated inside the seating space  142 . 
     The docking part  140  may include a flow path guide  146  disposed on the opposite side to the docking opening  143  in the second direction B in the seating space  142  and formed in a curved surface. 
     The flow path guide  146  may be provided in a curved shape in which the flow guide connected to extend in the second direction B is connected to extend in the first direction A. 
     As described above, since the docking opening  143  is formed toward the second direction B and the suction device  130  is disposed downward of the docking part  140  in the first direction A, the suction air current generated by the suction device  130  and flowing toward the dust collecting chamber  20  may collide with a portion in which the first direction A and the second direction B cross each other, which causes noise or pressure loss. 
     The flow path guide  146  may be formed on the opposite side to the docking opening  143  in the second direction B in the seating space  142 , which is a portion in which the first direction A and the second direction B cross each other, to guide the suction air current such that the suction air current flowing in the first direction A is caused to flow in the second direction B smoothly, or vice versa. 
     Hereinafter, a cleaning apparatus  1  according to another embodiment of the disclosure will be described. The components for the present embodiment except the dust collecting chamber  20  are the same as those of the cleaning apparatus according to the embodiment described above, and therefore a description thereof will be omitted. 
       FIG.  8    is a cross-sectional perspective view of a part of a vacuum cleaner before the vacuum cleaner is docked onto a docking station in a cleaning apparatus according to another embodiment of the disclosure.  FIG.  9    is a cross-sectional perspective view of a part of a vacuum cleaner before the vacuum cleaner is docked onto a docking station in a cleaning apparatus according to another embodiment of the disclosure. 
     Referring to  FIG.  8   , the dust collecting chamber  20  may include an elastic member  27  disposed on the rotation shaft  21   c  of the dust collecting chamber door  21 . 
     The elastic member  27  may be provided in the same shape as a torsion spring. 
     The elastic member  27  may be provided for the dust collecting chamber door  21  to be biased toward the body  22 . 
     Accordingly, even when the dust collecting chamber door  21  is set into an openable state by the fixing member  25  of the dust collecting chamber  20  being pressed, the dust collecting chamber door  21 , which is elastically supported by the elastic member  27 , may remain closed unless an external force is generated. 
     However, in this case, when a suction air current is generated by the suction device  130 , the suction air current provides the dust collecting chamber door  21  with an external force in a direction to open the dust collecting chamber door  21  so that the dust collecting chamber door  21  is opened and the foreign substances collected in the dust collecting container  20  are caused to flow into the collecting part  150  through the seating space  142  and thus collected in the collecting part  150 . 
     In addition, referring to  FIG.  9   , the dust collecting chamber  20  may include a pair of magnetic members  28  disposed on the body  22  and the dust collecting chamber door  21 , respectively. 
     A first magnetic member  28   a  of the pair of magnetic members  28  may be disposed on the body  22 , and a second magnetic member  28   b  of the pair of magnetic members  28  may be disposed on the dust collecting chamber door  21 . 
     Accordingly, even when the dust collecting chamber door  21  is set into an openable state by the fixing member  25  of the dust collecting chamber  20  being pressed, the dust collecting chamber door  21 , which is magnetically supported by the pair of magnetic members  28 , may remain closed unless an external force is generated. 
     However, in this case, when a suction air current is generated by the suction device  130 , the suction air current provides the dust collecting chamber door  21  with an external force in a direction to open the dust collecting chamber door  21  so that the dust collecting chamber door  21  is opened and the foreign substances collected in the dust collecting container  20  are caused to flow into the collecting part  150  through the seating space  142  and thus collected in the collecting part  150 . 
     Hereinafter, a cleaning apparatus  1  according to another embodiment of the disclosure will be described. The components for the embodiment except an opening guide are the same as those of the cleaning apparatus according to the embodiment described above, and therefore a description thereof will be omitted 
       FIG.  10    is a cross-sectional perspective view of a part of a vacuum cleaner in a state in which the vacuum cleaner is docked onto a docking station in a cleaning apparatus according to another embodiment of the disclosure, and  FIG.  11    is a cross-sectional perspective view of a part of a vacuum cleaner docked onto a docking station with an opening guide driven in a cleaning apparatus according to another embodiment of the disclosure. 
     Since the fixing member  25  is pressed in response to the dust collecting chamber  20  being docked onto the docking station  100 , the dust collecting door  21  may be maintained in an openable state. In this case, as described above, when there is no external force on the dust collecting chamber door  21 , the dust collecting chamber door  21  is not opened. 
     However, when an unexpected external force is applied to the docking station  100 , the external force is applied to the dust collecting chamber door  21  so that the dust collecting chamber door  21  may be opened and foreign substances collected in the dust collecting chamber  20  may be scattered to the outside. 
     That is, when the dust collecting chamber door  21  is opened by an external force other than the suction air current in a state in which the suction device  130  is not driven, the foreign substances collected in the dust collecting chamber  20  may be scattered to the outside of the docking station  100 . 
     The docking station  100  may be provided to, when the cleaner  10  is docked, perform both a charging mode of charging the battery  16  of the cleaner  10  and a suction mode of driving the suction device  130  to discharge foreign substances inside the dust collecting chamber  20 , or perform one of a charging mode and a suction mode. 
     That is, the user may control the docking station  100  so that, when the cleaner  10  is docked onto the docking station  100 , only the charging mode is performed. When the dust collecting chamber door  21  is opened in a state in which the suction mode is not in operation, foreign substances may be scattered to the outside. 
     In order to solve such a limitation, the docking station  100  according to the embodiment of the disclosure may include an opening guide  147  allowing the fixing member  25  of the docked dust collecting chamber  20  to be pressed only when the suction device  130  is driven. 
     The opening guide  147  may be provided in the shape of a protrusion or a rib protruding toward the center of the front inner circumferential surface  144  from the front inner circumferential surface  144 . 
     The opening guide  147 , when the dust collecting chamber  20  is inserted into the docking part  140  through the docking opening  143  and docked, may be disposed at an inner side of the docking part  140  in the second direction B from the fixing member  25  of the dust collecting chamber  20 . 
     Accordingly, the opening guide  147  may be provided to prevent the fixing member  25  from being pressed in a state in which the dust collecting chamber  20  is docked. 
     Therefore, since the fixing member  25  is not pressed even when the dust collecting chamber  20  is docked onto the docking part  140 , the dust collecting chamber door  21  is prevented from being opened by an external force. 
     The docking part  140  may include a driving device  148  interworking with the opening guide  147  to drive the opening guide  147 . 
     The driving device  148  may drive the opening guide  147  to translate the opening guide  147  in the second direction B according to a signal from the controller (not shown) of the docking station  100 . 
     The driving device  148  may, upon receiving a signal from the controller (not shown) of the docking station  100  when the suction device  130  is driven, drive the opening guide  147  to be moved forward in the second direction B. 
     The driving device  148  may be provided in various configurations, such as a motor, a solenoid valve, and the like. 
     As the opening guide  147  moves forward, the opening guide  147  may be provided to press the fixing member  25 , causing the dust collecting chamber door  21  to be set into an openable state. 
     Therefore, the opening guide  147  and the driving device  148  may allow the fixing member  25  to be selectively pressed so that the dust collecting chamber door  21  is opened only when the suction device  130  is driven. Accordingly, foreign substances collected in the dust collecting chamber  20  are prevented from being unintentionally scattered to the outside. 
     In addition, although not shown in the drawings, the driving device  148  may be provided to be directly controlled by the user. That is, in addition to control of the controller (not shown) of the docking station  100  according to the driving of the suction device  130 , the user may separately input a signal for driving the driving device  148  to drive the driving device  148 . 
     The user may input a driving signal of the driving device  148  to the controller (not shown) of the docking station  100 , so that the user may control the driving device  148  separately from driving of the suction device  130 . 
     In addition, the disclosure is not limited thereto, and in order for the user to directly move the opening guide  147  using a physical force through an intermediate member (not shown) provided to interwork with the opening guide  147 , the disclosure may include a push button (not shown) and the like interworking with the intermediate member (not shown). 
     The push button (not shown) may be disposed on one side of the body housing  110  to allow a user to easily open the dust collecting chamber door  21  through the opening guide  147 . 
     Hereinafter, a cleaning apparatus  1  according to another embodiment of the disclosure will be described. The components for the embodiment except a docking station are the same as those of the cleaning apparatus according to the embodiment described above, and therefore a description thereof will be omitted. 
       FIG.  12    is a view illustrating a state in which a vacuum cleaner of a cleaning apparatus according to another embodiment of the disclosure is docked onto a docking station. 
     Referring to  FIG.  12   , a body housing  210  of a docking station  200  may be provided to have a long axis extending in the first direction A. 
     A docking surface  211  of the body housing  210  may be provided to have a long axis extending in a third direction D having an inclination with respect to the first direction A, unlike the above described embodiment of the disclosure. 
     Accordingly, the docking surface  211  may be provided to extend in a direction inclined with respect to the first direction A, which is an upper and lower side direction. 
     Since the docking space  211  includes a docking opening  143  into which the dust collecting chamber  20  is inserted, the cleaner  10  may be docked onto the docking station  100  in a direction of the docking surface  211  in the docking station  200 . The cleaner  10  may be provided to be docked onto the docking station  200  in a fourth direction E perpendicular to the third direction D. The fourth direction E may be provided in a direction inclined with respect to the second direction B. 
     The cleaner  10  may be docked onto the docking station  200  in a direction perpendicular to a direction in which the long axis of the docking surface  211  extends in the docking station  200 . The cleaner  10  may be provided to be docked onto the docking station  200  in the fourth direction E perpendicular to the third direction D. 
     Since the direction in which the cleaner  10  is docked onto the docking station  200  is provided in the fourth direction E oblique with respect to the second direction B, which is the horizontal direction, the user may easily dock the cleaner  10  onto the docking station  200 . 
     Although specific embodiments of the disclosure have been shown and described, the above embodiments are for illustrative purpose only, and it would be appreciated by those skilled in the art that changes and modifications may be made in these embodiments without departing from the principles and scope of the disclosure, the scope of which is defined in the claims and their equivalents.
