It may include a base 400 including a second surface, and frictional force providing parts 410 and 420 formed on the second surface to provide frictional force between the handle part 35 and a wall surface in contact therewith, The providing parts 410 and 420 may include a plurality of protrusions extending in different directions on the second surface.

Specifically, the frictional force providing parts 410 and 420 are arranged to be spaced apart from each other along a second direction perpendicular to the first direction and extending along the first direction, respectively, between the handle part 35 and the wall surface to prevent the friction force. A plurality of first protrusions 410 providing frictional force in two directions, and each extending along the second direction and arranged to be spaced apart from each other along the first direction, between the handle part 35 and the wall surface, the first protrusion 410 It may include a plurality of second protrusions 420 providing frictional force in a direction.

The plurality of first protrusions 410 may protrude from the second surface at different heights, and may form a height that gradually increases along a direction away from the second protrusion 420 . That is, the plurality of first protrusions 410 may protrude from the base 400 along a third direction perpendicular to the first direction and the second direction, respectively, and each first protrusion 410 may protrude from the first direction. Heights in three directions may gradually increase in the order of arrangement along the second direction.

In one embodiment, when seven first protrusions 410 are formed, a height ratio of the plurality of first protrusions 410 may be 2:2.2:2.5:2.7:3:3.2:3.5. As the plurality of first protrusions 410 have the same height ratio as above, the frictional force providing unit 410 provides stronger frictional force as the handle 35 of the cleaner 1 slides upward and downward from the wall surface. may be provided.

The plurality of second protrusions 420 may be formed symmetrically with respect to one axis of the second surface in the first direction, and may form a height that gradually increases along a direction away from one axis in the first direction. That is, the plurality of second protrusions 420 may protrude from the base 400 along the third direction, and the height of each second protrusion 420 in the third direction is from the center to the edge. It may gradually increase in the order of being disposed along the first direction until it is disposed in the first direction.

In example embodiments, the height ratio of the second protrusion 420 disposed at the center and at the edge of the second protrusion 420 may be about 2:2.8. In one embodiment, when seven second protrusions 420 are formed, a height ratio of the plurality of second protrusions 420 may be 2.8:2.5:2.2:2:2.2:2.5:2.8. As the plurality of second protrusions 420 have the same height ratio as described above, the frictional force providing unit 410 provides all the elements when the handle 35 of the cleaner 1 has a rounded shape in the width direction. The two protrusions 420 may come into close contact with the wall surface, and accordingly, the handle portion 35 of the cleaner 1 may provide strong frictional force so as not to slide from the wall surface in the left and right directions.

In exemplary embodiments, the friction force providing unit 40 may be made of a material different from that of the handle unit 35 . In one embodiment, the handle part 35 may be made of a plastic material that does not have elasticity, and the frictional force providing part 40 may be made of a plastic material that has elasticity.

Meanwhile, FIGS. 3 to 7 show that each of the first protrusion 410 and the second protrusion 420 is formed of seven, but the concept of the present invention is not necessarily limited thereto, and the first protrusion 410 and the second protrusion 410 The two protrusions 420 may be formed in more or less than seven, respectively.

Referring to FIG. 7 , the friction force providing unit 40 may be installed to partially cover a rear portion and an upper portion of the handle portion 35, respectively.

Specifically, the handle part 35 extends along the longitudinal direction of the extension pipe 20 and is formed in the front of the handle part 35, and the first extension part 35a, and a direction different from the length direction of the extension pipe 20 A connecting portion (35b) extending along and at least partially forming a curved shape constituting the upper portion of the handle portion 35, and extending along the longitudinal direction of the extension tube 20 to form a rear portion of the handle portion 35. It may include two extension parts 35c. The first extension part 35a and the second extension part 35c may be connected by a connection part 35b.

At this time, the plurality of first protrusions 410 may be provided to cover a portion adjacent to the second extension portion 35c among portions of the connecting portion 35b, and the plurality of second protrusions 420 may be provided to cover the second extension portion. Among the portions of (35c), it may be provided to cover a portion adjacent to the connection portion (35b), and accordingly, the frictional force providing portion 40 is provided between the wall surface and the second extension portion (35c) and between the wall surface and the connection portion (35b). Each may be provided to provide frictional force.

In exemplary embodiments, the plurality of first protrusions 410 do not contact the wall surface when the second extension portion 35c and the wall surface are disposed in parallel, but the second extension portion 35c moves up and down from the wall surface. When the connecting portion 35b faces the wall surface by sliding in the direction, it can be arranged to contact the wall surface. At this time, the plurality of first protrusions 410 are formed to have a height that gradually increases from the closest to the second protrusion 420 to the farthest from the second protrusion 420, resulting in frictional force. The providing part 40 may provide gradually increased frictional force as the connecting part 35b slides in the vertical direction along the wall surface.

In exemplary embodiments, the plurality of second protrusions 420 are disposed in the center or closest to the center corresponding to the rounded surface of the second extension 35c to the edge or closest to the edge. Accordingly, the plurality of second protrusions 420 may be disposed to contact the wall surface in a state in which the second extension portion 35c and the wall surface are parallel to each other. .

As described above, the apparatus for supporting a vacuum cleaner according to exemplary embodiments of the present disclosure may include a first protrusion 410 and a second protrusion 420 respectively extending in directions perpendicular to each other. The protrusion 410 may provide frictional force in a direction perpendicular to the wall surface, and the second protrusion 420 may provide frictional force in a direction horizontal to the wall surface.

The cleaner support device may be installed on the handle part 35 of the cleaner 1, and the cleaner 1 may be operated by the first protrusion part 410 while the handle part 35 leans against a wall surface. Slipping in the vertical direction can be prevented, and slipping in the horizontal direction can be prevented by the second protrusion 420 . Accordingly, the cleaner 1 can maintain a standing state by itself without a user's manipulation by the cleaner support device.

8 is a block diagram for explaining configurations of a cleaner support device and a cleaner according to exemplary embodiments of the present invention.

Referring to FIG. 8 , the cleaner 1 according to exemplary embodiments of the present invention includes a power supply unit 501 for storing and providing power, a sensor unit 503 for detecting tilting of the cleaner body 30, It may include a driving part 520 for moving the cleaner 1 through rotation of a wheel or cleaning pad part 15 provided under the suction nozzle 10, and in exemplary embodiments of the present invention The cleaner supporting apparatus according to the present invention may further include a braking unit 510 for stopping driving of the driving unit 520 and a control unit 500 for controlling driving of the braking unit 510 .

At this time, the shape of the braking unit 510 is not particularly limited, and may be variously modified depending on the shape of the traveling unit 520 .

For example, when the driving unit 520 is composed of a driving motor, a driving shaft, and a driving wheel, the braking unit 510 is formed in the form of a first locking part (not shown) for limiting the driving of the driving motor itself. Alternatively, it may be formed in the form of a second catching part (not shown) or a third catching part (not shown) for limiting the rotation of the driving shaft or the driving wheel itself.

For example, the locking part may be provided in a way to limit the rotation of the motor itself when the motor rotates, as the term suggests, or provided in a form of holding the wheel so as to limit the rotation of the wheel rather than limiting the rotation of the motor. It could be.

In addition, even when the above-described first to third hanging parts are not provided, the vacuum cleaner support device may be provided in the form of an anti-slip pad (not shown) to limit the running of the driving part 520 . The non-slip pad may be disposed at a position that does not interfere with driving during cleaning.

That is, the anti-slip pad may be disposed at a position to limit the driving of the driving unit 520 only when the cleaner body 30 is disposed parallel to the wall surface.

For example, the anti-slip pad may be disposed at the foremost side of the lower housing provided under the suction nozzle 10 in a state where the cleaner body 30 is disposed parallel to the wall surface.

Therefore, when the user performs a cleaning operation using the cleaner 1, the non-slip pad may not come into contact with the cleaning floor, so that the running of the cleaner 1 is not restricted or hindered by the non-slip pad. can This is because the lower housing may be disposed at an acute angle with respect to the cleaning floor instead of being parallel to the cleaning floor when the cleaning operation is performed.

Specifically, the cleaning pad unit 15 may maintain a constant height from the cleaning floor surface to the air inlet by disposing a drum wheel assembly (not shown) at the center of the lower front portion. The drum wheel assembly may include a front lower protrusion including a drum wheel accommodating hole in the center, a drum wheel inserted into the drum wheel accommodating hole, and a rotating shaft coupling the drum wheel to the drum wheel accommodating hole. Here, the drum wheel is designed to have a relatively large diameter in the center, so that the movement of the cleaner 1 can be assisted with relatively little force.

At this time, the brake unit 510 may have a structure for limiting the drum wheel itself, or may have a structure for limiting the axis of rotation.

Meanwhile, the brake unit 510 may be controlled by the control unit 500 to be automatically driven when the power of the cleaner 1 is turned off.

Also, the brake unit 510 may be controlled by the sensor unit 503 to be automatically driven when the cleaner body 30 is tilted over a specific level.

The type of sensor unit 503 is not particularly limited.

For example, the sensor unit 503 may be configured as a gyro sensor to measure the inclination of the cleaner body 30 .

Since the gyro sensor is a sensor that measures a change in orientation of an object by using a property of maintaining an initially set direction, the control unit 500 detects a situation where the user finishes or stops cleaning through the gyro sensor, and controls the braking unit. 510 can be controlled to operate.

In this case, the brake unit 510 may be controlled to be automatically driven by the controller 500 when the inclination of the cleaner body 30 is measured by the gyro sensor to be greater than or equal to a predetermined value.

Alternatively, the sensor unit 503 may be configured as a distance sensor to measure the distance between the cleaner body 30 and the cleaning floor.

In this case, the brake unit 510 may be controlled to be automatically driven by the control unit 500 when the distance between the cleaner body 30 and the cleaning floor is measured by the distance sensor to be greater than or equal to a preset value.

Specifically, in the case of sensing the longest distance from the cleaning floor, the cleaner body 30 is disposed perpendicular to the cleaning floor, and in the case of using the cleaner body 30, the distance sensor extends from the cleaning floor to the distance sensor. The position of is smaller than when the cleaner body 30 is disposed perpendicular to the cleaning floor. Therefore, when the distance sensor senses a value greater than the preset distance value, the braking unit 510 may operate because the user has finished cleaning or stopped cleaning.

The type of distance sensor is not particularly limited. For example, the distance sensor may include an ultrasonic sensor or an IR sensor (infrared layer). That is, the operation method of the distance sensor may exist in various ways.

That is, the type of distance sensor may be variously applied within a range easy to those skilled in the art.

As described above, in the vacuum cleaner support device according to exemplary embodiments of the present invention, the driving part 520 includes the frictional force providing part 40 including the first protrusion part and the second protrusion part respectively extending in a direction perpendicular to each other. ) may further include a braking unit 510 for limiting the driving, in which case the grip unit 35 of the cleaner 1 is prevented from slipping from the wall surface and at the same time the driving unit 520 sweeps the cleaning floor. By limiting running along, the support effect of the cleaner 1 can be maximized.

Although various embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications are possible to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments and should not be defined, and should be defined by not only the claims to be described later, but also those equivalent to these claims.
