The cleaner body 10 has a suction motor for generating a suction force. The suction device 20 is capable of guiding the dust-containing air to the cleaner body 10 when the suction motor is driven to generate a suction force.

The suction device 20 may include a suction portion 21 for sucking dust on a surface to be cleaned (for example, a floor surface), and a connecting portion 22, 23, 24 for connecting the suction portion 21 to the cleaner body 10 . The connecting portions 22, 23, 24 may include an extension tube 24 connected to the suction portion 21, a handle 22 connected to the extension tube 24, and a suction hose 23 connecting the handle 22 to the cleaner body 10.

The cleaner body 10 includes a body portion 110 that forms an overall appearance.

The cleaner body 10 may further include a moving wheel 102 rotatably coupled to the body portion 110. A pair of moving wheels 102 may be provided and the pair of moving wheels 102 may be coupled to both sides of the body portion 110, respectively.

The body portion 110 can include a grip portion 104 that is grasped by a user. The user can grasp the grip portion 104 while lifting or tilting the body portion 110.

The vacuum cleaner body 10 can further include a battery 106 for powering.

The battery 106 can be detachably coupled to the body portion 110. With the battery 106 coupled to the body portion 110, the battery 106 can be integrated with the body portion 110. Therefore, the battery 106 moves together with the body portion 110.

The battery 106 can provide the power required for all operations of the vacuum cleaner 1. The battery 106 may be a secondary battery that can be charged and discharged. A power cord (not shown) for providing commercial power can be separately connected to the battery 106.

The cleaner body 10 further includes a dust container 120 that stores dust sucked by the suction device 20. Although the dust container 120 may have a cylindrical shape as shown, the shape of the dust container 120 is not limited thereto.

The dust container 120 may have a suction weir 124 through which dust is drawn in. The suction dam 124 may be disposed on the upper surface portion of the dust container 120 as shown. Therefore, the air introduced into the suction weir 124 is guided downward and moved to the storage space.

The dust container 120 may be detachably mounted on the body portion 110. A storage space for collecting dust introduced into the suction dam 124 may be formed inside the dust container 120.

The dust container 120 may be disposed on the front side of the body portion 110, and the side surface portion of the dust container 120 may be at least partially made of a transparent material such that the user confirms the dust collected in the storage space.

The vacuum cleaner 1 may include a dust separating portion (not shown) for separating dust and air sucked in the suction device 20 from each other. The dust separating portion may be manufactured as an object separate from the dust container 120, or may form a module with the dust container 120. For example, the dust separating portion may be disposed inside the dust container 120, and dust separated from the dust separating portion may be collected on the lower side of the dust container 120.

Fig. 2 is a view showing a state in which the cleaner body and the suction device are separated from each other in Fig. 1; and Fig. 3 is a view showing a state in which the dust container of Fig. 2 is separated from the main body.

Referring to Figures 2 and 3, the cleaner body 10 can include a connector 134 that is coupled to the suction device 20. The connector 134 is directly connected to the suction hose 23 so that dust-containing air can be introduced therein. In other words, one side of the connector 134 is coupled to the suction hose 23 and the other side is coupled to the suction weir 124. Therefore, the connecting member 134 connects the suction hose 23 and the suction dam 124 to each other.

The connector 134 can be in communication with the dust container 120. Therefore, the air introduced into the suction hose 23 can be introduced into the dust container 120 through the connection member 134.

The suction dam 124 may be disposed on one side of the dust container 120, and dust is introduced by drawing the suction 124. As shown, the suction weir 124 may be disposed on an upper portion (or an upper surface portion) of the dust container 120.

Further, the suction dam 124 may be formed to face the front side. Here, the front side refers to the portion of the suction hose 23 with respect to the cleaner body 10.

In addition, as shown, the connector 134 may be disposed at an upper portion of the dust container 120. Since both the suction weir 124 and the connecting member 134 are disposed at the upper portion of the dust container 120, the length of the flow path of the air introduced from the suction hose 23 can be minimized.

The suction hose 23 may include fitting portions 231, 232, 233 for improving airtightness when coupled with the connector 134.

The fitting portions 231, 232, 233 are capable of connecting the suction hose 23 to and from the connector 134. As shown, the fitting portions 231, 232, 233 can be formed in multiple steps.

The fitting portions 231, 232, 233 may include a first fitting portion 231, a second fitting portion 232, and a third fitting portion 233. The first fitting portion 231 and the second fitting portion 232 are inserted into the inside of the connecting member 134. Therefore, the first fitting portion 231 and the second fitting portion 232 are collectively referred to as an insertion portion, and may be referred to as a first insertion portion and a second insertion portion, respectively. The third fitting portion 233 is provided outside the connector 134. The third fitting portion 233 may be in contact with the end of the connector 134 to limit the insertion depth of the insertion portion.

The cleaner body 10 further includes a cover member 130 movably disposed in the body portion 110.

The cleaner body 10 may further include a connecting member 13 that connects the cover member 130 and the body portion 110 to each other. For example, the cover member 130 may be rotatably coupled to the body portion 110 through the connection member 13.

The cover member 130 can include a connector 134. Therefore, the connector 134 can move together with the cover member 130.

The cover member 130 may shield at least one side of the dust container 120. The cover member 130 may shield at least one side of the dust container 120 and may be coupled to the dust container 120. The cover member 130 can be coupled to the dust container 120 when the cover member 130 is closed, and separated from the dust container 120 when the cover member 130 is opened.

For example, the cover member 130 may be coupled to an upper portion of the dust container 120.

The dust container 120 can be separated from the body portion 110 as shown in FIG.

The body portion 110 can include a base portion 108 on which the dust container 120 is seated. The base portion 108 can be disposed at a lower portion of the dust container 120 as shown. The base portion 108 may form a coupling portion (not shown) for coupling to a lower surface portion of the dust container 120.

Meanwhile, the lower surface portion of the dust container 120 may be referred to as one side of the dust container 120, and the upper surface portion of the dust container 120 may be referred to as the other side of the dust container 120. Since the cover member 130 is coupled to the dust container 120 from the upper side of the dust container 120, the cover member 130 can be seen to be disposed on the side opposite to the base portion 108.

The state in which the cover member 130 is opened and the state in which the cover member 130 is closed will be specifically described below.

4 is a perspective view showing a cover member of the cleaner body when it is opened; FIG. 5 is a longitudinal sectional view of FIG. 4; and FIG. 6 is a perspective view showing a cover member of the cleaner body being closed; FIG. 6 is a longitudinal sectional view of the figure.

Referring to FIGS. 4 to 7, when the cover member 130 is opened, the user grips the grip portion 104 and lifts the cover member 130 upward or rotates the cover member 130 rearward. On the other hand, when the cover member 140 is closed, the user can cause the cover member 130 to rotate the cover member 130 downward or forward.

With the cover member 130 open, the user can take out the dust container 120 to the outside. At this time, the suction dam 124 of the dust container 120 is exposed to the outside.

In the case where the cover member 130 is closed, at least one side of the dust container 120 is shielded by the cover member 130. When one side of the dust container 120 is shielded by the cover member 130, the suction dam 124 is also shielded by the cover member 130.

However, since the cover member 130 does not shield the side surface portion of the dust container 120, the side surface portion of the dust container 120 is exposed to the outside. Therefore, since the side surface portion of the dust container 120 is at least partially made of a transparent material, the user can visually confirm the amount of dust collected in the storage space inside the dust container 120.

When the suction weir 124 is shielded by the cover member 130, the suction weir 124 comes into contact with the outlet portion of the connector 134. Therefore, the connector 134 is in communication with the suction weir 124. At this time, the connecting members 134 may be arranged in a row in the air introducing direction of the suction weir 124.

The first space portion 135 is formed inside the connecting member 134, and the second space portion 125 is formed inside the suction dam 124. When the cover member 130 is closed, the first space portion 135 and the second space portion 125 space portion are directly connected to each other.

Meanwhile, when the cover member 130 is closed, the rear end of the connecting member 134 and the front end of the suction dam 124 are in close contact with each other to be in an airtight state, and the air passing through the connecting member 134 does not leak to the outside, and all the air can It is introduced into the interior of the dust container 120.

Hereinafter, it will be described in more detail. For convenience of explanation, the direction in which the suction hose 23 is connected (the left side in FIG. 5) is referred to as the front direction, and the direction in contact with the dust container 120 (the right side in FIG. 5) is referred to as the rear direction.

When the cover member 130 is closed, the open rear end of the connector 134 can extend to the inside of the cover member 130 and extend to a position corresponding to the open front end of the suction dam 124.

The first sealing portion 136 may be formed at a rear end of the connecting member 134, and the second sealing portion 126 may be formed at a front end of the suction dam 124. The first seal portion 136 and the second seal portion 126 may be formed in respective shapes at positions facing each other, and may be configured to be in close contact with each other and coupled to each other when the cover member 130 is closed.

More specifically, the first seal portion 136 may be formed to be inclined and may be inclined forward in the downward direction. The second seal portion 126 may be inclined in the same direction as the first seal portion 136 and may also be inclined forward in the downward direction.

Meanwhile, the direction of the inclined surfaces of the first seal portion 136 and the second seal portion 126 may be formed to correspond to the rotational direction in which the cover member 130 is opened and closed. The direction of the inclined surfaces of the first seal portion 136 and the second seal portion 126 may be formed to be tangent to the radius of rotation of the cover member 130.

In other words, in order to naturally slide the first seal portion 136 and the second seal portion 126 in a position spaced apart from the rotation center of the cover member 130 when the cover member 130 is rotated, the cover member 130 is naturally slid with each other. The center of rotation is located at the rear end of the cover member 130, and when the cover member 130 is rotated, the slopes of the first seal portion 136 and the second seal portion 126 may be formed to have the same slope as the tangent to the radius of rotation of the cover member 130.

When the cover member 130 is rotatably operated to be closed by the bevel structure of the first seal portion 136 and the second seal portion 126, the cover member 130 can be effectively airtight without the connection member 134 and the suction dam 124 interfering with each other.

The interior of the connector 134 and the interior of the suction weir 124 may define a first space portion 135 and a second space portion 125, respectively. At this time, the rear end of the first space portion 135 and the front end of the second space portion 125 may have sizes corresponding to each other. The first seal portion 136 and the second seal portion 126 may be formed to have the same inclined surface. Therefore, the first space portion 135 and the second space portion 125 can have a completely connected structure in a state where the cover member 130 is closed.

When the connector 134 and the suction weir 124 are formed, the first seal portion 136 and the second seal portion 126 may be formed together. In other words, the first seal portion 136 and the second seal portion 126 may be made of a plastic material, respectively, and may be integrally formed with the joint member 134 and the suction weir 124.

A sealing member for airtightness may be mounted on the first seal portion 136 and the second seal portion 126, if necessary. A sealing member may be formed around the open end of the first seal portion 136 and the second seal portion 126 and may be mounted on at least one of the first seal portion 136 and the second seal portion 126. The sealing member may be made of a material having elasticity such as rubber, silicone, and sponge. Therefore, when the cover member 130 Upon closure, compression through the sealing member can provide complete airtightness between the first seal portion 136 and the second seal portion 126. Further, elasticity is provided when the cover member 130 is closed or opened, thereby mitigating impact when the cover member 130 is closed, and easy initial rotation when the cover member 130 is opened.

Of course, the first seal portion 136 and the second seal portion 126 may be made of a separate material having elasticity, if necessary. In other words, the first seal portion 136 and the second seal portion 126 are respectively made of an elastic material such as rubber, silicone, and sponge, and then fixedly mounted at the rear end of the joint 134 and the front end of the suction weir 124.

At this time, the first sealing portion 136 and the second sealing portion 126 may be installed to be inclined, or surfaces contacting each other may be formed to be inclined. The first sealing portion 136 and the second sealing portion 126 having elasticity may be formed to have a predetermined thickness to be compressed with each other in a state where the cover member 130 is closed. By the first sealing portion 136 and the second sealing portion 126 being made of an elastic material, the first sealing portion 136 and the second sealing portion 126 can be completely airtight, and the impact of the cover member 130 upon opening and closing can be alleviated and Easy to open.

In the case where the first seal portion 136 and the second seal portion 126 are made of an elastic material, when the cover member 130 is closed, the first seal portion 136 and the second seal portion 126 are in close contact with each other while being pressed against each other. Therefore, the first seal portion 136 and the second seal portion 126 can be in contact with each other in a compressed state in a state where the cover member 130 is closed, and the airtight performance can be further improved between the link member 134 and the suction dam 124.

Hereinafter, a case where the suction hose 23 is attached to the connector 134 will be described.

Fig. 8 is a perspective view showing a state in which the suction device is coupled to the cleaner body; Fig. 9 is a longitudinal sectional view of Fig. 8.

Referring to Figures 8 and 9, the suction hose 23 is connected to the connector 134. The front end (the left side in FIG. 9) of the connecting member 134 connected to the suction hose 23 can be defined as an inlet portion and the rear end of the exhaust air (the right side in FIG. 9) can be defined as an outlet portion. The outlet portion of the connector 134 faces the suction dam 124 and is capable of contacting each other.

At this time, the outlet portion of the connector 134 can communicate with the suction weir 124. The first sealing portion 136 of the connector 134 is in contact with the second sealing portion 126 of the suction weir 124, and the connector 134 and the suction weir 124 are in full communication with each other.

Specifically, the air discharged from the suction hose 23 can be introduced into the inside of the dust container 120 through the first space portion 135 and the second space portion 125 in this order. The flow path from the first space portion 135 and the second space portion 125 to the dust container 120 may be defined as a suction flow path F.

As shown, the suction flow path F is introduced from the connector 134 into the suction weir 124 and then directed down 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 the second space portion 125.

When the connecting member 134 and the suction weir 124 are connected to each other, the first space portion 135 and the second space portion 125 are connected to each other, thereby forming a flow path in which the first flow path and the second flowing flow path are connected to each other.

In this state, the flow path is linearly connected through the close contact of the first sealing portion 136 with the second sealing portion 126, and the suction hose 23 is also linearly connected to the connecting member 134 so as to be introduced through the suction hose 23. The air can flow linearly to the dust container 20 at the shortest distance.

As described above, the airtightness between the suction hose 23 and the connecting member 134 can be maintained by the fitting portions 231, 232, 233.

The first fitting portion 231, the second fitting portion 232, and the third fitting portion 233 may each have a gradually increasing diameter in this order. Therefore, a step can be formed between the first fitting portion 231 and the second fitting portion 232, and a step can be formed between the second fitting portion 232 and the third fitting portion 233.

The first fitting portion 231 and the second fitting portion 232 are inserted into the inside of the first space portion 135.

The connector 134 can have steps 134a, 134b. At least a portion of the fitting portions 231, 232, 233 may be sandwiched by the step portions 134a, 134b to limit the insertion range. Further, the step portions 134a, 134b are in surface contact with the fitting portions 231, 232, 233 to improve airtightness between the fitting portions 231, 232, 233 and the first space portion 135.

The step portions 134a, 134b may include a first step portion 134a and a second step portion 134b.

The first step portion 134a may be disposed in the first space portion 135. The end of the second fitting portion 232 may be in contact with the first step portion 134a.

The second step portion 134b may be disposed on the outer side of the connector 134. The end of the third fitting portion 233 may be in contact with the second step portion 134b.

The suction hoses 23 may be arranged in a line with the air flow direction in the first space portion 135. Therefore, the resistance of the air discharged from the suction hose 23 and flowing to the first space portion 135 is reduced.

As described above, in the vacuum cleaner 1 of the present invention, since the suction hose 23, the connector 134, and the suction weir 124 are arranged in a line, the resistance of the air discharged from the suction hose 23 is minimized. The stepped portion 134a of the suction hose 23 can extend to a position adjacent to the suction weir 124 in a state of being inserted into the inside of the connecting member 134. Therefore, the suction hose 23 can be in a state of being aligned with the suction weir 124 inside the connecting member 134. Therefore, the air discharged from the suction hose 23 can flow directly to the suction weir 124.

Further, the first seal portion 136 and the second seal portion 126 formed on the joint member 134 and the suction weir 124 can be brought into close contact with each other in an inclined state to effectively maintain the airtight state. Therefore, leakage of gas can be prevented.

Therefore, the air flow loss inside the cleaner body 10 can be minimized, and therefore the suction efficiency of the cleaner 1 can be improved.

In addition to the above embodiments, various other embodiments of the invention will be possible.

The configuration of another embodiment of the present invention will be the same as the configuration of the above-described embodiment except for some configurations, and the same names are used for the same configuration, and a detailed description thereof will be omitted.

Fig. 10 is a view showing a state in which the body portion of the cleaner body is inclined forward according to another embodiment of the present invention; Fig. 11 is a view showing a state in which the body portion is inclined rearward; and Fig. 12 is a view showing a state according to the present invention A configuration diagram of a support portion of another embodiment.

Referring to FIGS. 10 through 12, the cleaner body 1000 includes a body portion 1110, a moving wheel 1120, and a battery 1130.

The body portion 1110 may include a dust container 1105 for storing dust sucked by the suction device 1160. A pair of moving wheels 1120 may be coupled to both sides of the body portion 1110, respectively. The battery 1130 can be detachably coupled to the body portion 1110.

The portion where the connector 1103 is disposed may be defined as the front side with respect to the vertical line V passing through the center of rotation of the moving wheel of the cleaner body 1000, and the portion where the battery 1130 is disposed may be defined as the rear side. Further, the case where the main body portion 1110 rotates on the front side refers to the case where the main body portion 1110 rotates in the counterclockwise direction in the drawing (refer to FIG. 10), and the case where the main body portion 1110 rotates on the rear side means that the main body portion 1110 is along Rotate clockwise in the figure (see Figure 11).

The cleaner body 1000 may further include a driving portion for driving the moving wheel 1120. The cleaner body 1000 can control the driving of the moving wheel 1120 through the control portion according to the sensing information of the sensing portion, and the sensing portion senses the movement of the cleaner body 1000.

In the case where the sensing portion is in the OFF state, the moving wheel 1120 may not be driven. In this case, the body portion 1110 is inclined in accordance with the position of the center of gravity. For example, when the center of gravity of the body portion 1110 is located on the front side of the vertical line V passing through the center of rotation of the moving wheel 1120, the body portion 1110 is inclined forward as shown in FIG. 10; and when the center of gravity of the body portion 1110 is at the vertical line V On the rear side, the body portion 1110 is inclined rearward as shown in Fig. 11.

When the sensing portion is opened, the control portion may control the driving of the moving wheel 1120 such that the center of gravity of the body portion 1110 is located on the vertical line V passing through the center of rotation of the moving wheel. In this case, the lower surface B of the body portion 1110 may be spaced apart from the bottom surface G as shown in FIG.

The cleaner body 1000 may further include a rear wheel unit 1140. The rear wheel unit 1140 is disposed on the rear side of the lower surface of the body portion 1110, and may have a function for restricting the angle at which the body portion 1110 is inclined rearward.

The rear wheel unit 1140 can further include an extension 1144. The auxiliary wheel 1142 can be rotatably coupled to one side of the extension 1144. The other side of the extension 1144 can be rotatably coupled to the body portion 1110 by a rotating shaft 1146. The extension 1144 can be rotated up or down within the range of a-a'.

The rear wheel unit 1140 may further include an elastic member 1150. For example, the elastic member 1150 may be a torsion spring. The end 1152 of the resilient member 1150 can be supported by the body portion 1110 and the other end 1153 of the resilient member 1150 can be supported by the extension 1144. The elastic member 1150 can apply an elastic force such that the extension 1144 rotates in a clockwise direction in the drawing.

When the body portion 1110 is inclined as far as possible forward, the front side portion of the lower surface B of the body portion 1110 can come into contact with the bottom surface G. Therefore, the maximum rotation angle of the body portion 1110 can be restricted in the forward direction.

Conversely, when the body portion 1110 is inclined rearward, the rear wheel unit 1140 can be in contact with the bottom surface G. Therefore, the maximum rotation angle of the body portion 1110 and the rear side can be restricted. Therefore, it is possible to prevent the body portion 1110 from being turned forward or backward.

When the body portion 1110 is rotated as far as possible rearward, the lower surface B of the body portion 1110 may form a predetermined angle with the bottom surface G. At this time, the angle between the lower surface B of the body portion 1110 and the bottom surface G may be about 17 to 20 .

Battery 1130 can include a cover 1131. The cover 1131 may be exposed to the outside in a state where the battery 1130 is mounted on the body portion 1110. Therefore, the cover 1131 can form at least the appearance of the body portion 1110 portion. Further, the user can separate the battery 1130 from the body portion 1110 or couple the battery 1130 to the body portion 1110 without disassembling the body portion 1110.

Hereinafter, the process of connecting and detaching the battery 1130 from the body portion 1110 will be described in detail. However, the following description is limited to the case where the center of gravity of the body portion 1110 is positioned forward with the battery 1130 removed from the body portion 1110, and in the case where the battery 1130 is coupled to the body portion 1110, the center of gravity of the body portion 1110 is located at the rear side. .

Fig. 13 is a view sequentially showing a state in which the battery is coupled to the body of the cleaner.

Fig. 13(a) is a view showing a state in which the battery 1130 is separated from the main body portion 1110; Fig. 13(b) is a view showing a state in which the battery 1130 is coupled to the main body portion 1110; and Fig. 13(c) This is a diagram showing a state in which the main body portion 1110 is inclined rearward.

The body portion 1110 is formed with a battery coupling portion 1107, and the battery 1130 is coupled to the battery coupling portion 1107. The battery coupling portion 1107 may be formed by pressing a portion of the body portion 1110.

The battery coupling portion 1107 is formed on the lower side of the body portion 1110 such that the battery 1130 is coupled to the lower side of the body portion 1110. For example, in a state where the battery 1130 is mounted on the body portion 1110, the center of gravity of the battery 1130 may be located on the lower side of the center of rotation of the moving wheel 1120.

Therefore, when the battery 1130 is coupled to the body portion 1110, since the center of gravity of the body portion 1110 can be moved downward, the operational stability of the cleaner body 1000 can be improved.

Although the running stability is improved when the battery 1130 is coupled to the lower side of the body portion 1110, since the battery 1130 must be coupled to the lower side of the body portion 1110, the user may be uncomfortable due to the coupling of the battery 1130.

However, in a state where the battery 1130 is separated from the body portion 1110, the center of gravity of the body portion 1110 may be positioned on the front side of the vertical line passing through the center of the moving wheel 1120. Therefore, when the battery 1130 is separated from the body portion 1110, the body portion 1110 can be tilted forward relative to the moving wheel 1120.

When the body portion 1110 is inclined forward, the front portion of the lower surface of the body portion 1110 is in contact with the bottom surface, at which time the battery coupling portion 1107 is inclined upward. Therefore, the user can easily assemble the battery 1130.

The battery 1130 may be coupled to the body portion 1110 in an oblique direction through a coupling guide provided in the battery coupling portion 1107. Specifically, the insertion direction S of the battery 1130 may be at an acute angle to the vertical line V and the bottom surface, respectively. Therefore, in the case where the front portion of the lower surface of the body portion 1110 is in contact with the bottom surface, the insertion direction S of the battery 1130 forms an acute angle with the bottom surface.

When the battery 1130 is coupled to the body portion 1110, the center of gravity of the body portion 1110 can be moved rearward. In other words, the center of gravity of the body portion 1110 may be positioned after the vertical line passing through the center of the moving wheel 1120 in a state where the battery 1130 is coupled to the body portion 1110.

In other words, when the battery 1130 is coupled to the body portion 1110, the body portion 1110 can be tilted rearward relative to the moving wheel 1120. At this time, the rear wheel unit 1140 selectively contacts the bottom surface. At this time, the lower surface B of the body portion 1110 forms a predetermined angle θ with the bottom surface G.

Fig. 14 is a view sequentially showing a state in which the battery and the cleaner body are separated.

Specifically, Fig. 14(a) is a diagram showing a state before the battery 1130 is separated from the main body portion 1110; and Fig. 14(b) is a diagram showing a state in which the battery 1130 is separated from the main body portion 1110.

In order to separate the battery 1130 from the main body portion 1110, the user can tilt the main body portion 1110 by directly applying a force to the main body portion 1110. Next, the user is able to separate the battery 1130 in the opposite direction to the insertion direction S.

When the battery 1130 is separated from the body portion 1110, the center of gravity of the body portion 1110 moves forward again. Therefore, the body portion 1110 can maintain the forward tilt state.

As described above, in the vacuum cleaner of the present invention, in a state where the battery 1130 is mounted on the body portion 1110, the body portion 1110 is rotated rearward such that the lower surface portion of the body portion 1110 is separated from the bottom surface. In other words, the body portion 1110 can be supported at two points through the moving wheel 1120 during movement. In this case, the cleaner body 1000 can move more easily over the obstacle, and since the running friction acting on the moving wheel 1120 is reduced, the user can reduce the labor required to move the cleaner body 1000.

Even in the case where the battery 1130 is separated from the body portion 1110, since the center of gravity of the body portion 1110 moves forward and the body portion 1110 rotates forward, the battery coupling portion 1107 provided on the rear lower side of the body portion 110 rises. Therefore, the user can easily couple the battery 1130 to the battery coupling portion 1107.
