In addition, the guide part 12 is provided with an elastic member 13 for supporting a guide protrusion to be described later.

The moving member 100 is preferably formed in a cylindrical shape for rotation in a state connected to the air intake portion (11).

The guide protrusion 111 accommodated in the guide part 12 is formed outside the moving member 100. The guide protrusion 111 is formed around the outer side of the moving member as a whole. The guide protrusion 111 is provided with a first to-be-detected body 112 that is the detection target of the first detection unit 122. The first to-be-detected body 112 is also provided along the circumference of the first guide protrusion as a whole.

The guide protrusion 112 is supported by the elastic member 13. The elastic member 13 exerts a force of the guide protrusion 112 to move backward to the guide protrusion 112.

In addition, a plurality of second to-be-detected bodies 114, which are the sensing targets of the second sensing unit 124, are provided at positions spaced apart from the first to-be-detected body 112 of the moving member 100.

Referring to FIG. 5, the vacuum cleaner 1 according to the present embodiment includes a driving unit for rotating the main wheel 20, a first to-be-detected body 112 and a second to-be-detected body provided in the moving member ( 114, the first sensing unit 122 and the second sensing unit 124 sensing the sensing targets 112 and 114, and the information detected by the sensing units 122 and 124. Control unit 90 for controlling the operation of the drive unit is included.

In detail, the pair of main wheels 70 includes a left wheel and a right wheel. The drive unit includes a left wheel motor 94 for rotating the left wheel and a right wheel motor 96 for rotating the right wheel. Alternatively, the driving units 94 and 96 may include a single motor for simultaneously rotating the pair of main wheels.

1 to 7, the user performs cleaning of the bottom surface while moving the suction nozzle 30 while holding the handle 40. At this time, the part other than the bottom surface can be cleaned, but in this embodiment, the case of cleaning the bottom surface using the suction nozzle 30 will be described by way of example.

Here, since the force is not applied to the movable member 110 before the cleaning is performed, the first sensing member 112 is spaced apart from the first sensing unit 122 by the elastic member 13.

Then, when the user performs cleaning while moving the suction nozzle 30 back and forth, if the process is repeated, the suction nozzle 30 substantially moves forward little by little.

When the suction nozzle 30 is moved forward in this cleaning process, the connection hose 60 is pulled forward accordingly. Then, the moving member 100 coupled with the connecting portion 62 of the connecting hose 60 is moved forward. When the movable member 100 moves forward, the elastic member 13 is contracted so that the movable member 10 moves forward.

When the moving member 110 moves forward, the first to-be-detected body 112 moves forward to be positioned above the first sensing unit 122. Then, the magnetism of the first to-be-detected body 112 is sensed by the first detector 122.

In this case, when the moving member 110 is moved forward, the cleaner body 10 is substantially pulled out.

Accordingly, the controller 90 drives the motors 94 and 96 for a predetermined time so that the main wheel 70 rotates in the direction in which the cleaner main body 10 moves forward. The cleaner body then moves forward.

When the cleaner main body 10 is advanced as described above, the movable member 100 is moved back by the restoring force of the elastic member, so that the first to-be-detected body 112 is moved to the first sensing unit 122. )

Of course, in the process of cleaning while advancing the suction nozzle, the moving member 100 may be rotated before the first sensing object is detected by the first sensing unit. However, the rotation angle of the movable member 100 is not very large in the process of pulling the connection hose, and since the plurality of second sensing objects 124 are spaced apart by a predetermined distance, the movement of the movable member 100 The possibility that the main body 10 is reversed by the rotation as opposed to the moving direction of the suction nozzle 10 is not great.

On the other hand, when the user moves the suction nozzle 30 to the rear, the connection hose 60 is bent close to the distance between the suction nozzle 30 and the main body 20. In this state, and in the process of bending the connection hose 60, the connection portion 62 of the connection hose is rotated.

That is, when the connection hose 60 is bent, the force that the connection hose tries to unfold acts as the connection part 62 so that the connection part 62 tries to move backward, but the main body 10 is stopped. Since the state is maintained, the connecting portion 62 is rotated by the force applied to the connecting portion 62.

In addition, the movable member 100 rotates together with the connection part 62, and thus the magnetism of any one of the plurality of second sensing objects 114 is sensed by the second sensing part 124.

Then, the controller 90 drives the respective motors 94 and 96 for a predetermined time so that the main wheel 70 is rotated in the direction in which the cleaner body 10 moves backward. Then, the cleaner body is reversed.

According to the present embodiment as described above, since the driving unit is operated by the movement of the moving member according to the movement of the suction nozzle, the cleaner body can be moved by itself, so that the user can move the cleaner body with little force. There is an advantage.

In addition, since the cleaner main body may move in a direction in which the user moves, the user may clean more easily while moving the surface to be cleaned.

In addition, since the cleaner main body can be moved by the driving unit, there is an effect that the cleaner main body can easily cross the obstacle or the like on the bottom surface.

In the present embodiment, the first sensing unit may be referred to as a translational movement sensing unit because it detects the translational motion of the moving member, and the second sensing unit may be referred to as a rotation sensing unit because it detects rotation of the moving member. .
