- The air contained dust is introduced into an introduction pipe provided in the main body through the suction nozzle and a connecting portion by the suction force of the suction motor. The air is sucked into an inside portion of the dust separating device through the introduction pipe. The air sucked into the dust separating device is separated from the dust in the process of flowing through the inside portion of the dust separating device. The dust separated from the dust separating device is collected in the dust collecting container through a dust discharging portion.
- Meanwhile, the introduction pipe extends upward from the dust separating device and a lower portion of the dust collecting container toward an inlet portion of the dust separating device in the inside portion of the main body (see
Fig. 3 of the related art). With such a structure, in the vacuum cleaner of the related art, the air sucked flows through the introduction pipe, causing a flow loss due to friction. Accordingly, there is a problem that the flowing amount of air introduced into the dust separating device is capable of being reduced, and the suction force of the vacuum cleaner is reduced. -

- In particular, the first sealing portion and the second sealing portion are made of an elastic material and are capable of being pressed and fixed to each other. In a state where the cover member is closed, since the first sealing portion and the second sealing portion are capable of being pressed and be in close contact with each other, the air which is introduced into the suction port through the connector is not leaked, thereby being capable of improving suction performance of the vacuum cleaner.
- In addition, since the sealing member is provided between the connector and the suction port of the dust container, the airtight between the connector and the dust container is capable of being ensured.
- In addition, since the distance between the suction port of the end dust container and the suction hose is formed to be relatively short, it is advantageous for securing a space of the inside portion of the cleaner main body.
- In addition, since the suction hose, the connector, and the suction port are capable of being aligned on the same extension line with each other, the flow resistance is capable of being minimized in flow of the air discharged from the suction hose and flowing the suction port.
- In addition, since the end of the suction hose is inserted into the inside of the connector and extends to a position adjacent to the suction port, the air discharged from the suction hose is capable of being effectively introduced into the suction port.
- In the vacuum cleaner of the present invention, since the center of gravity of the battery is located forward and rotates forward in a state where the battery is separated from the main body portion, the battery is capable of being easily coupled from the cleaner main body.
- In addition, since the cleaner main body is supported at two points by a pair of moving wheels, the cleaner main body is capable of easily moving over obstacles such as thick carpets and a blanket.
- In addition, since the mounting position of the battery is located on the lower side of the cleaner main body, the center of gravity of the cleaner main body moves downward, thereby being capable of improving the running stability of the cleaner main body.
- In addition, since the support portion is provided at the rear side of the main body portion, it is possible to prevent the main body portion from being turned over rearward.

Fig. 2 is a view illustrating a state where the cleaner main body and the suction device ofFig. 1 are separated from each other andFig. 3 is a view illustrating a state where the dust container ofFig. 2 is separated from the main body portion. - Referring to
Fig. 2 andFig. 3 , the cleanermain body 10 may include aconnector 134 connected to thesuction device 20. Theconnector 134 is directly connected to thesuction hose 23 so that dust-containing air is capable of being introduced therein. In other words, a side of theconnector 134 is coupled to thesuction hose 23 and the other side thereof is coupled to thesuction port 124. Accordingly, theconnector 134 connects thesuction hose 23 and thesuction port 124 with each other. - The
connector 134 may communicate with thedust container 120. Accordingly, the air introduced into thesuction hose 23 is capable of being introduced into thedust container 120 through theconnector 134. - A

Therefore, the firstfitting portion 231 and the secondfitting portion 232 are collectively referred to as insertion portions, which may be referred to as a first insertion portion and a second insertion portion, respectively. The thirdfitting portion 233 is provided outside theconnector 134. The thirdfitting portion 233 may be in contact with the end of theconnector 134 to limit the insertion depth of the insertion portion. - The cleaner
main body 10 further includes acover member 130 movably provided in themain body portion 110. - The cleaner
main body 10 may further include the connectingmember 13 connecting thecover member 130 and themain body portion 110 with each other. For example, thecover member 130 may be rotatably connected to themain body portion 110 by the connectingmember 13. - The
cover member 130 may include theconnector 134. Accordingly, theconnector 134 is capable of moving along with thecover member 130. - The
cover member 130 may shield at least one side of thedust container 120. Thecover member 130 may shield at least one side of thedust container 120 and may couple with thedust container 120. Thecover member 130 is capable of being coupled with thedust container 120 when thecover member 130 is closed and separated from thedust container 120 when thecover member 130 is opened. - For example, the
cover member 130 may be coupled to the upper portion of thedust container 120. - The
dust container 120 may be separated from themain body portion 110 as illustrated inFig. 3 . - The
main body portion 110 may include aseat portion 108 on which thedust container 120 is seated. Theseat portion 108 may be disposed on a lower portion of thedust container 120 as illustrated in the drawings. Theseat portion 108 may be formed with a coupling portion (not illustrated) for coupling with a lower surface portion of thedust container 120. - Meanwhile, the lower surface portion of the
dust container 120 may be referred to as a side of thedust container 120 and the upper surface portion of thedust container 120 may be referred to as the other side of thedust container 120. Since thecover member 130 is coupled to thedust container 120 from the upper side of thedust container 120, thecover member 130 is capable of being seen to be provided on a side opposite to theseat portion 108. - Hereinafter, a state where the
cover member 130 is opened and a state where thecover member 130 is closed will be described specifically. -
Fig. 4 is a perspective view illustrating the cleaner main body when the cover member is opened,Fig. 5 is a longitudinal sectional view ofFig. 4 ,Fig. 6 is a perspective view illustrating the cleaner main body when the cover member is closed, andFig. 7 is a longitudinal sectional view ofFig. 6 . - Referring to
Fig. 4 to Fig. 7 , when thecover member 130 is opened, a user grasps thegrip portion 104 and lifts thecover member 130 upward or rotates thecover member 130 rearward. On the other hand, when the cover member 140 is closed, the user is capable of lowering thecover member 130 downward or rotating thecover member 130 forward. - In a case where the
cover member 130 is opened, the user is capable of taking out thedust container 120 to the outside of the vacuum cleaner. At this time, thesuction port 124 of thedust container 120 is exposed to the outside of the vacuum cleaner. - In a case where the
cover member 130 is closed, at least one side of thedust container 120 is shielded by thecover member 130. When a side of thedust container 120 is shielded by thecover member 130, thesuction port 124 is also shielded by thecover member 130. - However, since the
cover member 130 does not shield a side surface portion of thedust container 120, the side surface portion of thedust container 120 is exposed to the outside. Accordingly, since the side surface portion of thedust container 120 is at least partially made of transparent material, the user is capable of visually confirming the amount of dust collected in the storage space of the inside portion of thedust container 120. - When the
suction port 124 is shielded by thecover member 130, thesuction port 124 is in contact with an outlet portion of theconnector 134. Accordingly, theconnector 134 communicates with thesuction port 124. At this time, theconnector 134 may be aligned with the air introducing direction at thesuction port 124. - A
first space portion 135 is formed in the inside of theconnector 134 and asecond space portion 125 is formed in the inside of thesuction port 124. When thecover member 130 is closed, thefirst space portion 135 and thesecond space portion 125 are directly connected to each other. - Meanwhile, when the
cover member 130 is closed, a rear end of theconnector 134 and a front end of thesuction port 124 are in close contact with each other to be in an airtight state and the air passing through theconnector 134 is not leaked to the outside and all the air is capable of being introduced into the inside portion of thedust container 120. - Hereinafter, this will be described in more detail. For convenience of description, a direction in which the
suction hose 23 is connected (left side inFig. 5 ) is referred to as a front direction and a direction which is in contact with the dust container 120 (the right side inFig. 5 ) is referred to as a rear direction. - An opened rear end of the
connector 134 is capable of extending into the inside of thecover member 130 and extending to a position corresponding to an opened front end of thesuction port 124 when thecover member 130 is closed. - A
first sealing portion 136 may be formed at a rear end of theconnector 134 and asecond sealing portion 126 may be formed at a front end of thesuction port 124. Thefirst sealing portion 136 and thesecond sealing portion 126 may be formed in corresponding shapes at positions facing each other and may be configured to be in close contact and be coupled with each other when thecover member 130 is closed. - More specifically, the
first sealing portion 136 may be formed to be inclined, and may be inclined forward in the downward direction. Thesecond sealing portion 126 may be inclined in the same direction as that of thefirst sealing portion 136, and may be also inclined forward in the downward direction. - Meanwhile, a direction of the inclined surfaces of the
first sealing portion 136 andsecond sealing portion 126 may be formed to correspond to the rotation direction in which thecover member 130 is opened and closed. A direction of the inclined surfaces of thefirst sealing portion 136 and thesecond sealing portion 126 may be formed so as to correspond to a tangent of the rotating radius of thecover member 130. - In other words, the rotation center of the
cover member 130 is positioned at the rear end of thecover member 130, and when thecover member 130 rotates, slopes of thefirst sealing portion 136 and thesecond sealing portion 126 may be formed to have the same slope as the tangent of the rotation radius of thecover member 130 in order for thefirst sealing portion 136 and thesecond sealing portions 126 which are in positions spaced apart from the rotation center of thecover member 130 when rotating thecover member 130 to be close contact with each other while naturally sliding to each other. - The
cover member 130 is capable of being effectively airtight without theconnector 134 and thesuction port 124 being interfered with each other when thecover member 130 is rotatably operated to be closed by the slope structure of thefirst sealing portion 136 and thesecond sealing portion 126. - The inside portion of the
connector 134 and the inside portion of thesuction port 124 may form afirst space portion 135 and asecond space portion 125, respectively. At this time, the rear end of thefirst space portion 135 and the front end of thespace portion 125 may have a size corresponding to each other. Thefirst sealing portion 136 and thesecond sealing portion 126 may be formed to have the same inclined surface. Accordingly, thefirst space portion 135 and thesecond space portion 125 are capable of having a completely communicated structure in a state where thecover member 130 is closed. - The
first sealing portion 136 and thesecond sealing portion 126 may be formed together when theconnector 134 and thesuction port 124 are shaped. In other words, thefirst sealing portion 136 andsecond sealing portion 126 may be made of a plastic material, respectively and may be integrally shaped with theconnector 134 and thesuction port 124. - If necessary, a sealing member for airtight may be mounted on the
first sealing portion 136 and thesecond sealing portion 126. The sealing member may be formed around the opened end portions of thefirst sealing portion 136 and thesecond sealing portion 126 and may be mounted on at least one of thefirst sealing portion 136 and thesecond sealing portion 126. The sealing member may be made of a material having elasticity such as rubber, silicone, and sponge. Therefore, when thecover member 130 is closed, the complete airtight is capable of being provided between thefirst sealing portion 136 and thesecond sealing portion 126 by the compression of the sealing member. In addition, the elasticity is provided when thecover member 130 is closed or opened, thereby the impact is alleviated when thecover member 130 is closed, and the initial rotation is performed easier when thecover member 130 is opened. - Of course, the
first sealing portion 136 and thesecond sealing portion 126 may be made of a separate material having elasticity, if necessary. In other words, thefirst sealing portion 136 and thesecond sealing portion 126 are separately made of a material having elasticity such as rubber, silicone, and sponge, and then fixedly mounted on the rear end of theconnector 134 and the front end of thesuction port 24. - At this time, the
first sealing portion 136 and thesecond sealing portion 126 may be mounted to be inclined or the surfaces thereof which are in contact with each other may be formed to be inclined. Thefirst sealing portion 136 and thesecond sealing portion 126 having elasticity may be formed to have a predetermined thickness in order to be compressed with each other in a state where thecover member 130 is closed. Thefirst sealing portion 136 and thesecond sealing portion 126 are capable of being completely airtight by thefirst sealing portion 136 and thesecond sealing portion 126 made of an elastic material and the impact upon opening and closing of thecover member 130 is capable of being alleviated and opened easily. - In a case where the
first sealing portion 136 and thesecond sealing portion 126 are made of an elastic material, when thecover member 130 is closed, thefirst sealing portion 136 and thesecond sealing portion 126 are in close contact with each other while being pressed against each other. Accordingly, thefirst sealing portion 136 and thesecond sealing portion 126 may be in contact with each other in a compressed state in a state where thecover member 130 is closed and the airtight performance is capable of being further improved between theconnector 134 and thesuction port 124. - Hereinafter, a case where the
suction hose 23 is mounted on theconnector 134 will be described. -
Fig. 8 is a perspective view illustrating a state where the suction device is coupled to the cleaner main body, andFig. 9 is a longitudinal sectional view ofFig. 8 . - Referring to
Fig. 8 andFig. 9 , thesuction hose 23 is connected to theconnector 134. A front end (left side inFig. 9 ) to which thesuction hose 23 is connected in theconnector 134 is capable of being defined as an inlet portion and a rear end (right side inFig. 9 ) in which air is discharged is capable of being defined as an outlet portion. The outlet portion of theconnector 134 faces thesuction port 124 each other and is capable of being in contact with each other. - At this time, the outlet portion of the
connector 134 is capable of communicating with thesuction port 124. Thefirst sealing portion 136 of theconnector 134 and thesecond sealing portion 126 of thesuction port 124 are in contact with each other and theconnector 134 and the suction port may completely communicate with each other. - Specifically, the air discharged from the
suction hose 23 may introduces into the inside portion of thedust container 120 through thefirst space part 135 and thesecond space part 125 in this order. The flow path from thefirst space portion 135 and thesecond space portion 125 to the dust container 12 may be defined as a suction flow path F. - As illustrated in the drawings, the suction flow path F is introduced from the
connector 134 into thesuction port 124 and then guided downward to the storage space. - The suction flow path F may be divided into a first flow path defined in the
first space portion 135 and a second flow path defined in thesecond space portion 125. - The
first space portion 135 and thesecond space portion 125 are connected with each other when theconnector 134 and thesuction port 124 are connected with each other, thereby forming a flow path which is connected the first flow path and the second flow path with each other. - In this state, the flow path is linearly connected by the close contact of the
first sealing portion 136 and thesecond sealing portion 126, and thesuction hose 23 is also linearly connected to theconnector 134 so that the air introduced through thesuction hose 23 is capable of linearly flowing with the shortest distance toward thedust container 20. - As described above, the airtight between the
suction hose 23 and theconnector 134 is capable of being maintained by thefitting portions - The first
fitting portion 231, the secondfitting portion 232, and the thirdfitting portion 233 may have a diameter which is gradually increased in this order, respectively. Accordingly, a step may be formed between the firstfitting portion 231 and the secondfitting portion 232 and a step may be formed between the secondfitting portion 232 and the thirdfitting portion 233. - The first
fitting portion 231 and the secondfitting portion 232 are inserted into an inside portion of thefirst space portion 135. - The
connector 134 may have steppedportions fitting portions portions portions fitting portions fitting portions first space portion 135. - The stepped
portions portion 134a and a second steppedportion 134b. - The first stepped
portion 134a may be provided in thefirst space portion 135. The end of the secondfitting portion 232 may be in contact with the first steppedportion 134a. - The second stepped
portion 134b may be provided on an outside of theconnector 134. The end portion of the thirdfitting portion 233 may be in contact with the second steppedportion 134b. - The
suction hose 23 may be aligned in line with the air flow direction in thefirst space portion 135. Accordingly, the resistance of the air which is discharged from thesuction hose 23 and flows to thefirst space portion 135 is reduced. - As described above, in the
vacuum cleaner 1 of the present invention, since thesuction hose 23, theconnector 134, and thesuction port 124 are arranged in a line, the resistance of the air discharged from thesuction hose 23 is minimized. The steppedportion 134a of thesuction hose 23 is capable of extending to a position adjacent to thesuction port 124 in a state of being inserted into the inside portion of theconnector 134. Accordingly, thesuction hose 23 may be in a state of being aligned with thesuction port 124 in the inside portion of theconnector 134. Therefore, the air discharged from thesuction hose 23 is capable of flowing directly toward thesuction port 124. - In addition, the
first sealing portion 136 and thesecond sealing portion 126 formed on theconnector 134 and thesuction port 124 are capable of being in close contact with each other in a state of being inclined state to effectively maintain the airtight state. Accordingly, the leakage of the liquid is capable of being prevented. - Accordingly, the air flow loss in the inside portion of the cleaner
main body 10 is capable of being minimized, and as a result, the suction efficiency of thevacuum cleaner 1 is capable of being improved. - Various other embodiments of the present invention will be possible in addition to the embodiment described above.
- Configurations of another embodiment of the present invention will be the same as those of the embodiment described above except for some configurations, and the same names are used for the same configurations, and a detailed description thereof will be omitted.

Fig. 10 is a view illustrating a state where a main body portion of a cleaner main body is inclined forward according to another embodiment of the present invention.Fig. 11 is a view illustrating a state where the main body portion is inclined rearward.Fig. 12 is a view illustrating a configuration of a support portion according to another embodiment of the present invention. - Referring to
Fig. 10 to Fig. 12 , a cleanermain body 1000 includes amain body portion 1110, a movingwheel 1120, and abattery 1130. - The
main body portion 1110 may include adust container 1105 for storing dust sucked through asuction device 1160. A pair of movingwheels 1120 may be coupled to both sides of themain body potion 1110, respectively. T hebattery 1130 may be detachably coupled to themain body potion 1110. - A portion where the
connector 1103 is disposed may be defined as a front side and a portion where thebattery 1130 is disposed may be defined as a rear side, with respect to a vertical line V passing through the rotation center of the movingwheel 1120 in the cleanermain body 1000. In addition, a case where themain body portion 1110 rotates in the front side means that themain body portion 1110 rotates in the counterclockwise direction in the drawing (seeFig. 10 ) and a case where themain body portion 1110 rotates in the rear side means that themain body portion 1110 rotates in the clockwise direction in the drawing (seeFig. 11 ). - The cleaner
main body 1000 may further include a driving portion for driving the movingwheels 1120. The cleanermain body 1000 may control the driving of themobile wheel 1120 by the control portion according to sensing information of a sensing portion which senses the movement of the cleanermain body 1000. - In a case where the sensing portion is in an OFF state, the moving
wheel 1120 may not be driven. In this case, themain body portion 1110 is inclined according to a position of the center of gravity. For example, when the center of gravity of themain body portion 1110 is positioned in the front side of the vertical line V passing the rotation center of the movingwheel 1120, themain body portion 1110 is inclined forward as illustrated inFig. 10 , and when the center of gravity of themain body portion 1110 is positioned at the rear side the vertical line V, themain body portion 1110 is inclined rearward as illustrated inFig. 11 . - When the sensing portion is turned on, the control portion may control the driving of the moving
wheel 1120 such that the center of gravity of themain body potion 1110 is positioned on the vertical line V passing the rotation center of the movingwheel 1120. In this case, a lower surface B of themain body portion 1110 may be spaced apart from a bottom surface G as illustrated inFig. 11 . - The cleaner
main body 1000 may further include arear wheel unit 1140. Therear wheel unit 1140 is disposed on the rear side of the lower surface of themain body portion 1110 and may function to restrict an angle at which themain body portion 1110 inclined rearward. - The
rear wheel unit 1140 may further include an extendingportion 1144. Anauxiliary wheel 1142 may be rotatably connected to a side of the extendingportion 1144. The other side of the extendingportion 1144 may be rotatably connected to themain body potion 1110 by therotation shaft 1146. The extendingportion 1144 is capable of rotating upward or downward within the range of a-a'. - The
rear wheel unit 1140 may further include anelastic member 1150. For example, theelastic member 1150 may be a torsion spring. Anend 1152 of theelastic member 1150 is capable of being supported by themain body portion 1110 and theother end 1153 of theelastic member 1150 is capable of being supported by the extendingportion 1144. Theelastic member 1150 may apply an elastic force such that the extendingportion 1144 rotates in the clockwise direction in the drawing. - The front side portion of the lower surface B of the
main body portion 1110 is capable of being in contact with the bottom surface G when themain body portion 1110 is inclined forward as much as possible. Accordingly, the maximum rotation angle of themain body potion 1110 is capable of being limited in the forward direction. - Conversely, when the
main body potion 1110 is inclined rearward, therear wheel unit 1140 is capable of being in contact with the bottom surface G. Accordingly, the maximum rotation angle of themain body portion 1110 to the rear side is capable of being limited. Accordingly, themain body potion 1110 is capable of being prevented from being turned over forward or rearward. - The lower surface B of the
main body portion 1110 may form a predetermined angle □ with the bottom surface G when themain body portion 1110 rotates rearward as much as possible. At this time, an angle □ between the lower surface B of themain body portion 1110 and the bottom surface G may be approximately 17° to 20°. - The
battery 1130 may include acover 1131. Thecover 1131 may be exposed to the outside in a state where thebattery 1130 is mounted on themain body potion 1110. Accordingly, thecover 1131 is capable of forming at least a portion of an outer appearance of themain body portion 1110. In addition, the user is capable of separating thebattery 1130 from themain body potion 1110 or couple thebattery 1130 to themain body potion 1110 without disassembling themain body potion 1110. - Hereinafter, the process of attachment and detachment of the
battery 1130 to and from themain body potion 1110 will be described in detail. However, the following description is limited only that in a case where thebattery 1130 is removed from themain body potion 1110, the center of gravity of themain body potion 1110 is positioned forward and in a case where thebattery 1130 is coupled to themain body potion 1110, the center of gravity of themain body potion 1110 is located at the rear side. -
Fig. 13 is a view sequentially illustrating a state where the battery is coupled to the cleaner main body. -
Fig. 13A is a view illustrating a state where thebattery 1130 is separated from themain body potion 1110, andFig. 13B is a view illustrating a state where thebattery 1130 is coupled to themain body potion 1110 andFig. 13C is a view illustrating a state where themain body potion 1110 is inclined rearward. - The
main body portion 1110 is formed with abattery coupling portion 1107 to which thebattery 1130 is coupled. Thebattery coupling portion 1107 may be formed by a portion of themain body portion 1110 being depressed. - The
battery coupling portion 1107 is formed on the lower side of themain body portion 1110 so that thebattery 1130 is coupled to the lower side of themain body portion 1110. For example, the center of gravity of thebattery 1130 may be positioned at the lower side of the rotation center of the movingwheel 1120 in a state where thebattery 1130 is mounted on themain body potion 1110. - Therefore, when the
battery 1130 is coupled to themain body potion 1110, since the center of gravity of themain body potion 1110 is capable of being moved downward, running stability of the cleanermain body 1000 is capable of being improved. - Although the running stability is improved when the
battery 1130 is coupled to the lower side of themain body potion 1110, since thebattery 1130 must be coupled to the lower side of themain body potion 1110, the user may result in discomfort for coupling thebattery 1130. - However, the center of gravity of the
main body potion 1110 may be positioned in the front side of the vertical line passing through the center of the movingwheel 1120 in a state where thebattery 1130 is separated from themain body potion 1110. Accordingly, when thebattery 1130 is separated from themain body potion 1110, themain body potion 1110 is capable of being inclined forward about themobile wheel 1120. - As the
main body portion 1110 is inclined forward, the front portion of the lower surface of themain body portion 1110 is in contact with the bottom surface, and at this time, thebattery coupling portion 1107 is oriented obliquely upward. Accordingly, the user is capable of easily assembling thebattery 1130. - The
battery 1130 may be coupled to thebody portion 1110 in an oblique direction by a coupling guide portion provided in thebattery coupling portion 1107. Specifically, an inserting direction S of thebattery 1130 may be an acute angle with the vertical line V and the bottom surface, respectively. Therefore, in a case where the front portion of the lower surface of themain body potion 1110 is in contact with the bottom surface, the insertion direction S of thebattery 1130 forms an acute angle with the bottom surface. - When the
battery 1130 is coupled to themain body potion 1110, the center of gravity of themain body potion 1110 is capable of moving rearward. In other words, the center of gravity of themain body potion 1110 may be positioned behind the vertical line passing through the center of the movingwheel 1120 in a state where thebattery 1130 is coupled to themain body potion 1110. - In other words, when the
battery 1130 is coupled to themain body potion 1110, themain body potion 1110 is capable of being inclined rearward about themovement wheel 1120. At this time, therear wheel unit 1140 is selectively in contact with the bottom surface. At this time, the lower surface B of themain body portion 1110 forms a predetermined angle □ with the bottom surface G. -
Fig. 14 is a view sequentially illustrating a state where the battery is separated from the cleaner main body. - Specifically,
Fig. 14A is a view illustrating a state before thebattery 1130 is separated from themain body portion 1110 andFig. 14B is a view illustrating a state where thebattery 1130 is separated from themain body portion 1110. - In order to separate the
battery 1130 from themain body potion 1110, the user is capable of inclining themain body potion 1110 by directly applying a force to themain body potion 1110. Next, the user is capable of separating thebattery 1130 in a direction opposite to the insertion direction S. - When the
battery 1130 is separated from themain body potion 1110, the center of gravity of themain body potion 1110 moves forward again. Accordingly, themain body portion 1110 is capable of maintaining a forward inclined state. - As described above, in the vacuum cleaner of the present invention, in a state where the
battery 1130 is mounted on themain body potion 1110, themain body potion 1110 rotates rearward so that the lower surface portion of themain body potion 1110 is separated from the bottom surface. In other words, themain body potion 1110 is capable of being supported at two points by the movingwheel 1120 when running. In this case, the cleanermain body 1000 is capable of further easily moving over obstacles and since the running friction acting on themovement wheel 1120 is reduced, the user is capable of reducing labor force required for moving the cleanermain body 1000. - Even in a case where the
battery 1130 is separated from themain body potion 1110, since the center of gravity of themain body potion 1110 moves forward and themain body potion 1110 rotates forward, thebattery coupling portion 1107 provided on the rear lower side of themain body portion 110 rises. Accordingly, the user is capable of easily coupling thebattery 1130 to thebattery coupling portion 1107. - According to the embodiments, a suction efficiency of the vacuum cleaner can be enhanced thus the present the present invention has high industrial applicability.
