The wheel motor 632 can be built with a BLCD motor whose rotation is easy to control and light. And the several moving gears, which is a rotary shaft of the wheel motor 632 with the wheel gear 64 of the motor wheel 60 connect, slow down the rotation of the wheel motor 632 and then transfer the rotation to the motion wheel 60 ,

Meanwhile, the wheel motor assembly 63 further on a back than the turning center of the moving wheel 60 be installed. In particular, a Gehäuseinstallationsnut 633 , which is recessed inward, on the wheel motor housing 631 be educated. The housing installation groove 633 is recessed in a shape that the wheel hub 316a corresponds, and formed, to at least a part of the wheel hub 316a take. That is, while the wheel motor assembly 63 is installed, the housing installation groove 633 installed such that it has a second half portion of an outer surface of the wheel hub 316a surrounds and on a back of the wheel hub 316a is arranged. Therefore, the wheel motor assembly 63 allow the focus of the cleaner body 10 is arranged on a farther rear side while on the cleaner body 10 is installed.

And the wheel motor 632 is at a lower portion of the wheel motor housing 631 arranged, and the plurality of movable gears are above the wheel motor 632 arranged. That is, because the wheel motor 632 , which is relatively heavy, is arranged on the bottom, the center of gravity of the cleaner body 10 be arranged on a further lower side.

The lower ornament 315 that the exterior of the body part 30 that makes up outside the motor wheel 60 is exposed on the side section 316 be installed. The lower ornament 315 can along at least part of a circumference of the Bewegradrads 60 may be formed such that it has a curved surface that leads to a curved surface of the Bewegradrads 60 is continued, and thus can form a smooth appearance.

Multiple reinforcing ribs 316b which extend vertically may further on an inner surface of the side portion 316 , ie a surface opposite to a surface on which the wheel hub 316a is formed, be formed. Because the multiple reinforcing ribs 316b are formed, can be prevented that the side portion 316 be damaged by a load applied laterally. And the motorbike 60 can be kept in a stable coupled state.

Meanwhile, a detection part may further 306 on one side of the inner surface of the side portion 316 be provided. The detection part 306 may be a state of motion or a position of the cleaner body 10 capture and can drive the motion wheel 60 Taxes. The detection part 306 serves to control the movement of the cleaner body 10 and may include a gyro sensor or an acceleration sensor, which is typically widely used. Of course, instead of the gyro sensor or the acceleration sensor, various sensors or devices which control the movement of the cleaner body 10 capture as the capture part 306 be used.

The detection part 306 may be at an upper portion of the inner surface of the side portion 316 be installed. The detection part 306 can be a capture PCB 360a on which the gyro sensor is mounted, and a detection part fixing member 306b that the capture PCB 360a attached, embrace and is at the side portion 316 Installed. And a pair of fastening hooks 306c may be at the detection part attachment element 306b may be provided and may be in detection part mounting holes 316c on the side section 316 are formed, used and secured therein.

Meanwhile, the detection PCB 360a be formed to drive the wheel motor 632 to steer, which is provided on both sides. That is, a structure for controlling the gyro sensor and the wheel motor 632 can be built with a PCB.

As described above, the detection part 306 on the side section 316 installed and attached thereto, and an installation position of the detection part 306 may be located on a side of the turning center of the moving wheel 60 acting as the rotary shaft of the cleaner body 10 used is removed. When the cleaner body 10 is driven or stopped, therefore, a rotation angle, ie an inclination of the cleaner body 10 be recorded effectively.

While the cleaner body 10 in the stopped state, its center of gravity is behind the center of the motion wheel 60 arranged. Therefore, the cleaner body becomes 10 held in a state intended to be based on the center of the motion wheel 60 to turn clockwise. And the cleaner body 10 is maintained in a state in which he is from the rear wheel unit 70 , which is in contact with the ground. Consequently, a lower surface of the cleaner body 10 , in particular the first half section 312 to be kept at a predetermined angle.

In this state, the detection part determines 306 by the inclination of the cleaner body 10 ie the angle of the first half section 312 whether the cleaner body 10 is driven or stopped.

In particular, the wheel motor assembly 63 , the battery unit 38 and the main engine 35 behind the middle of the motor wheel 60 be arranged. Therefore, the center of gravity G of the cleaner body 10 further on a rear side than the turning center C of the moving wheel 60 arranged, and thus is the cleaner body 10 naturally, in the state intended to be based on the center of the moving wheel 60 to turn clockwise.

And the second half section 313 of the cleaner body 10 can from the rear wheel unit 70 in the second half section 313 the base 31 is installed. Therefore, the cleaner body can be prevented 10 is rotated excessively clockwise, and it can be stably maintained at a target angle α.

In particular, due to a characteristic of the vacuum cleaner 1 the dust in the dust container 50 accumulated after the vacuum cleaner 1 has been used. Taking into account this fact, the focus of the cleaner body 10 always arranged in its second half section and is from the rear wheel unit 70 held, and thus the cleaner body 10 regardless of an amount of dust, maintaining a constant inclination with respect to the ground while in the stopped state.

If the detection part 306 in this state, an angle of the first half section 312 recorded and confirmed that the first half section 312 maintains the target angle α, it is determined that the cleaner body 10 maintains a fixed position in the stopped state. Therefore, the main PCB controls 301 in that the wheel motor assembly 63 is not operated, causing the stopped state of the cleaner body 10 is maintained.

If the user meanwhile the handle 23 grips and moves forward to the vacuum cleaner 1 to use, becomes the cleaner body 10 due to a position of the handle 23 inclined. That is, the cleaner body 10 is turned counterclockwise so that the first half section 312 is moved further down.

At this point, the detection part detects 306 a change in the angle of the first half section 312 and determines according to the change of the angle a fact that the movement of the vacuum cleaner 1 starts. Therefore, the main PCB 301 determine that the cleaner body 10 is moved, and thus can the moving wheel 60 by driving the wheel motor assembly 63 rotate.

And if the movement of the cleaner body 10 is stopped again, the cleaner body 10 rotated by the center of gravity into an initial state, and the detection part 306 checks a fact that the angle of the first half section 312 coincides with the target angle α in the stopped state. Therefore, the main PCB 301 determine that the movement of the cleaner body 10 is complete, and can the wheel motor assembly 63 steer so that it stops.

Meanwhile, the lower surface of the cleaner body 10 ie the middle section 311 , the first half section 312 and the second half section 313 the base 31 , as in 11 represented, have a predetermined angle. The angle of each of the center section 311 , the first half section 312 and the second half section 313 can be set varied. Below is the angle of the base 31 in the stopped state of the cleaner body 10 described.

For example, the first half section 312 be designed so that it is inclined with respect to the ground at an angle of 27 °. The first half section 312 can hardly collide with the ground by allowing the first half section 312 even if the suction hose has the angle of 27 ° 24 is pulled and the cleaner body 10 is turned. Of course, the first half section 312 be in contact with the ground due to unexpected operation. In this case, the movement of the cleaner body 10 by a rolling motion of the front wheel 312a be carried out smoothly. Likewise, the first half section 312 due to the inclination of the first half section 312 be moved easily over the carpet, the door sill or the like while the cleaner body 10 is driven.

And the middle section 311 may be formed so that it is inclined at an angle of 7 ° with respect to the ground, while the cleaner body 10 is in the stopped state. When the motor wheel 60 by the drive of the wheel motor 632 is rotated, and thus the cleaner body 10 is driven, the cleaner body 10 turned by an angle of about 7 ° counterclockwise. While the cleaner body 10 is driven, the middle section 311 therefore kept in a horizontal state to the ground, and thus can be prevented that the bottom of the vacuum cleaner 1 is caught by foreign substances or the like in a room.

And the second half section 313 may be formed so that it is inclined at an angle of 10 ° with respect to the ground, while the cleaner body 10 is in the stopped state. Therefore, the cleaner body 10 around the center of gravity of the cleaner body 10 , which is eccentric to a backside, are turned clockwise while the cleaner body 10 is in the stopped state and can then be dropped on the ground.

That is, in the stopped state, the cleaner body 10 already in a state in which its second half section 313 is shifted downwards due to the center of gravity, and thus can regardless of the amount of in the dust container 50 stored dust in the through the rear wheel unit 70 maintained stable state.

Also, the second half section 313 due to the inclined second half section 313 be prevented from colliding with the ground when the suction hose 24 is pulled and the cleaner body 10 is rotated, and thus can be prevented, the rotation of the cleaner body 10 is limited.

Meanwhile, the movement wheel 60 a wheel frame 61 include, which is rotatable on the wheel hub 316a of the page section 316 is installed and where the wheel gear 64 installed, and its wheel ornamentation 62 an exterior of the motor wheel 60 forms by connecting it with an outer surface of the wheel frame 61 is coupled.

Likewise, a wheel gear installation section 612 at which the wheel gear 64 is attached, in a center of the wheel frame 61 educated. The wheel gear 64 can rotate on the wheel hub 316a be installed while attached to the wheel frame 61 is attached.

Meanwhile, there is a wheel opening 621 in a middle of the wheel ornament 62 formed, and a coupling element through which the wheel gear 64 and the wheel frame 61 can be coupled through the wheel opening 621 be attached. And a hubcap 623 can at the wheel opening 621 be installed and can the wheel opening 621 shield.

Meanwhile, the cleaner body 10 in 12 by a vertical extension line Lv, which is vertical to the ground (or the Ground surface) based on the rotation center C of the moving wheel 60 be divided into a front and a back.

And the cleaner body 10 can be defined by a horizontal extension line LH which extends horizontally with the ground (or ground surface) on a base between the main motor 35 and the battery unit 38 be divided into a top and a bottom.

The cleaner body 10 can be divided into four areas, ie four squares, by the vertical extension line Lv and the horizontal extension line LH. Hereunder, main structures of the cleaner body 10 based on the vertical extension line Lv and the horizontal extension line LH described.

The main engine 35 can be in a first quadrant of the cleaner body 10 that is, on a rear side of the vertical extension line Lv and an upper side of the horizontal extension line LH, be arranged. And the battery unit 38 may be in a fourth quadrant of the cleaner body 10 , that is, on a rear side of the vertical extension line Lv and a bottom of the horizontal extension line LH, be arranged. And a hole formed at a position where the connector is 401 or the suction hose 24 can be connected in a second quadrant of the cleaner body 10 , ie on a front side of the vertical extension line Lv and the top of the horizontal extension line LH. And at least part of a lower surface of the dust container 50 may be in a third quadrant of the cleaner body 10 , ie on the front side of the vertical extension line Lv and the bottom of the horizontal extension line LH.

Due to such an arrangement, the center of gravity G of the entire cleaner body 10 be arranged on the back of the vertical extension line Lv. At this time, the center of gravity G may be disposed on any of the top and the bottom of the horizontal extension line LH. However, the center of gravity G should be located in a position where a rear end of the cleaner body 10 or the rear wheel unit 70 is rotatable to be in contact with the ground.

Likewise, the center of gravity G may be arranged such that the rear end of the cleaner body 10 or the rear wheel unit 70 regardless of the amount of dust in the container 50 through the use of the vacuum cleaner 1 collected dust is in contact with the ground while the vacuum cleaner 1 is in the stopped state.

Likewise, the wheel motor assembly 63 also be arranged on the back of the vertical extension line Lv, so that the center of gravity G is more easily arranged on the back.

20 is a perspective view of the cover. And 21 is an exploded perspective view of the cover. And 22 FIG. 10 is a partial cross-sectional view illustrating a coupling structure of the cover member and the obstacle detection member. FIG.

As shown in the drawings, the cover 40 the upper portion of the cleaner body 10 and may be formed to have a structure having an upper end of the upper ornament 37 and an upper end of the dust container 50 shields.

The cover element 40 can generally be a cover base 42 and an outer cover 43 include. The cover base 42 forms a lower surface of the outer cover 43 and essentially shields the dust container 50 and the opened upper surface of the body part 30 from.

A cover member coupling portion 421 is at a rear end of the cover base 42 formed, and the Abdeckelementkopplungsabschnitt 421 can with an upper end of the body part 30 , in particular the rear end of the upper ornament 37 to be wave coupled. And a connection hole 422 that with the connector 401 may be connected to a front end of the cover base 42 be educated.

The obstacle detection element 44 can at the cover base 42 be provided. The obstacle detection element 44 serves to test an obstacle while the cleaner body 10 is driven, and may along a front surface of the cover base 42 be arranged.

Several obstacle detection elements 44 can be in a center of the front surface of the cover base 42 ie, both left and right sides based on the connector 401 be provided. That is, two obstacle detection elements 44 can each be on the left and right sides based on the center of the cover base 42 be provided, and each of the obstacle detection elements 44 may be formed such that it is using a laser sensor 441 has a detection range of about 25 °. And the several obstacle detection elements 44 may be arranged such that adjacent obstacle detection elements 44 directed in mutually different directions.

The obstacle detection elements 44 can front sensors 44b and 44c and side sensors 44a and 44d include. The front sensors 44b and 44c serve to capture the obstacle that is in front of the cleaner body 10 located. If the obstacle in front of the cleaner body 10 appears while the cleaner body 10 is driven, capture the front sensors 44b and 44c the obstacle. And the side sensors 44a and 44d serve to capture the obstacle located on a lateral side of the cleaner body 10 located. If the obstacle on the lateral side adjacent to the cleaner body 10 appears while the cleaner body 10 is driven by the lateral sensors 44a and 44d the obstacle. In particular, the lateral sensors allow 44a and 44d through a combination of the front sensors 44b and 44c that the cleaner body 10 without a collision with a corner of a wall surface is driven.

In particular, the front sensors 44b and 44c at each of the left and right sides of the connector 401 and may be arranged to emit light in a diagonal direction between the front and the side. That is, as in 22 shown, centers of the front sensors 44b and 44c be arranged at positions relative to a center of the connector 401 turned clockwise and counterclockwise by 45 °. Therefore, the centers of the front sensors 44b and 44c make an angle of 90 ° with respect to each other.

And since the detection area of each of the obstacle detection elements 44 is about 25 °, is between the front sensors 44b and 44c an unrecognized area S is generated. The unrecognized area S may have an angle of 65 °. The unrecognized area S lies in a region in which the suction hose 24 may be arranged while the cleaner body 10 is driven, and that prevents the suction hose 24 from the front sensors 44b and 44c as the obstacle is considered. That is, even if the user has the suction hose 24 moves while performing a cleaning operation, the front sensors 44b and 44c be prevented from the suction hose 24 erroneously recognize as the obstacle, and thus can be prevented that the cleaner body 10 is driven abnormally.

The lateral sensors 44a and 44d are farther on a back than the front sensors 44b and 44c arranged and arranged so that they the light in the direction of the lateral side of the cleaner body 10 emit. That is, the side sensors 44a and 44d can be based on the connector 401 be arranged on both sides to form an angle of about 90 °. Therefore, the side sensors 44a and 44d Grasp the obstacle on the lateral side of the cleaner body 10 appears.

Meanwhile, each of the side sensors can 44a and 44d be formed so that it has a shorter detection distance than that of each of the front sensors 44b and 44c Has. For example, any of the front sensors 44b and 44c be formed so that it has a detection distance L1 of about 600 mm toward the front, and each of the lateral sensors 44a and 44d may be formed to have a detection distance L2 of about 350 mm toward the lateral side.

Because the obstruction is on the front of the cleaner body 10 has a high probability of having the cleaner body 10 obstruct while the cleaner body 10 is driven, it is necessary to detect the obstacle, which is located at a great distance. In the case of the obstacle located on the lateral side, there is little possibility that it is the cleaner body 10 obstructed while the cleaner body 10 is driven, and if a distant object, which is located on the lateral side, as the obstacle is detected, it may be impossible for the cleaner body 10 driving normally.

In particular, when the detection path L2 of each of the lateral sensors 44a and 44d shorter than the L1 of each of the front sensors 44b and 44c is set, the cleaner body 10 easily avoid a wall surface or corner when passing the wall surface or corner.

Meanwhile, the obstacle detection elements 44 the laser sensor 441 and a sensor substrate 442 on which the laser sensor 441 installed, include. Elements for driving or controlling the laser sensor 441 may also be on the sensor substrate 442 be installed. Of course, instead of the laser sensor 441 various devices such as an ultrasonic sensor, a proximity sensor, and a vision camera that detect the obstacle located on the front side as the obstacle detection element 44 be used.

48 is a view showing a stop state of the cleaner body 10 represents.

As shown in the drawing, the focus G of the cleaner body is located 10 while the cleaner body 10 is not moved and is in the stopped state, farther on a rear side than the turning center C of the moving wheel 60 ,

In this condition, it is intended that the cleaner body 10 based on the turning center C of the moving wheel 60 is rotated clockwise (in a normal direction), and the second half section 313 the base 31 is lowered and the first half section 312 is raised.

At this point prevents the rear wheel unit 70 that is in contact with the ground that the second half section 313 the base 31 is lowered excessively, keeps the base 31 elastic and allows the cleaner body 10 is kept in the stable state.

That is, both the motion wheel 60 as well as the rear wheel 70 are in contact with the floor and the cleaner body 10 is stored on three points. Likewise, the back of the cleaner body 10 , on which the center of gravity is located, in a lowered state, and thus can the cleaner body 10 maintain the stable position in the stopped state.

Therefore, the first half portion of the cleaner body 10 regardless of the presence or absence of the dust in the dust container 50 or the amount of dust in the target angle α are kept. In this state, the detection part 306 a position of the cleaner body 10 grasp by its angle.

That is, the detection section 306 confirms that the first half section 312 is held in the target angle α, determines that the cleaner body 10 is not moved and kept in the stopped state, and thus enables the wheel motor 632 is not driven and is kept in the stopped state.

49 is a view showing a driving condition of the cleaner body 10 represents.

When the user moves forward as shown in the drawing while holding the handle 23 engages to perform the cleaning operation, the one with the handle 23 connected suction hose 24 drawn. And there with the suction hose 24 connected connectors 401 on the cover 40 is arranged, the force is at a position above the center of rotation C of the moving wheel 60 applied. Consequently, the cleaner body becomes 10 by the torque based on the rotation center C of the moving wheel 60 turned counterclockwise (in the reverse direction).

An angle β between the first half section 312 and the floor may be in accordance with an amount of on the connector 401 applied force is changed, but is smaller than the target angle α in the stopped state of the cleaner body 10 , And even if that on the connector 401 applied force is greater, is the first half section 312 due to the front wheel 312a not in direct contact with the ground, and the front wheel 312a is in contact with the floor, and the vacuum cleaner 1 can be moved stably.

While the vacuum cleaner 10 for example, is driven stable, is the middle section 311 in a horizontal state with the ground. And due to the counterclockwise movement of the cleaner body 10 forms the first half section 312 an angle of 20 ° with respect to the ground, and the second half section 313 forms an angle of 10 °. In this state, the cleaner body 10 to be driven ideally. The angle of the cleaner body 10 however, may be changed according to a momentary pulling force or a condition of the ground.

The detection part 306 detects the position of the cleaner body 10 and determines the rotation of the moving wheel 60 , When the angle β between the first half section 312 and the bottom is smaller than the target angle α, the detecting part drives 306 the wheel motor 632 and turns the motor wheel 60 in the counterclockwise direction. Due to the rotation of the motor wheel 60 can the cleaner body 10 be driven forward.

At this point, the detection part 306 the wheel motor 632 at the moment when the detected angle becomes smaller than the target angle α, drive immediately. If necessary, the wheel motor can 632 are driven when one of the detection part 306 detected change value exceeds a specified range (eg 1 ° to 2 °).

Since the detection part 306 however, a change in the angle β between the first half section 312 and the ground can detect a rotational speed of the wheel motor assembly 63 be controlled proportionally to the change of the angle. When the angle β between the first half section 312 and, for example, the ground quickly becomes smaller, becomes a rotation speed of the wheel motor 632 also faster, and thus can the cleaner body 10 with a high Speed to be moved forward. And if the angle β between the first half section 312 and the ground becomes relatively slow smaller, the speed of the wheel motor 632 become relatively slower.

When a distance from the user due to the forward movement of the cleaner body 10 can get closer to the connector 401 applied force become smaller or eliminated. When the on the connector 401 applied force is removed, the cleaner body 10 based on a turning center of the moving wheel 60 Turned clockwise and is in the in 46 illustrated state. At this point, the detection part 306 confirm that the angle between the first half section 312 and the bottom of the target angle is α, and thus can drive the wheel motor assembly 63 to stop.

Therefore, if the user moves while holding the handle 23 picks up the vacuum cleaner 1 to use the force on the connector 401 applied, and the cleaner body 10 is moved forward. And if the cleaner body 10 is moved forward and the distance becomes closer to the user who is on the connector 401 applied force weaker. When the on the connector 401 applied force is weaker becomes the cleaner body 10 stopped while being turned clockwise due to the center of gravity.

If, however, in a state in which the vacuum cleaner 1 is driven, the angle between the lower surface of the dust container 50 or the first half section 312 and the ground (the ground surface) is smaller than the target angle (α <target angle <β), the drive of the wheel motor 63 be slowed down. That is, up to the target angle, a predetermined speed is maintained, and its deceleration begins when the detected angle reaches the target angle, and the wheel motor assembly 63 is stopped when the detected angle is the target angle. Of course, the determination of the angle based on the middle section 311 and the second half section 313 instead of the first half section 312 be achieved.

When such a process is repeated, the purifier body follows 10 the user according to the movement of the user, and thus, although the user can not separate operation for moving the cleaner body 10 a self-contained movement is achieved.

Because the first half section 312 is designed such that it is inclined, the cleaner body 10 be effectively moved across the threshold or obstacle when the door sill or obstacle is on its front while it is being driven. That is, even in a situation where the obstacle is generated, the cleaner body can 10 be driven stable and can be moved continuously over the obstacle.

And if it is necessary to move over a high obstacle, or the user's grip 23 raises, becomes the cleaner body 10 based on the center of the motion wheel 60 Turned clockwise, and thus can the second half section 313 be moved in the direction of the ground. At this point is the rear wheel unit 70 in the contact state with the ground and can prevent the second half section 313 excessively lowered or overturned. And the rear wheel unit 70 holds the second half section 313 elastic, so that the cleaner body 10 in the 46 is shown when the external force from the cleaner body 10 Will get removed.

Meanwhile, the cleaner body 10 Grasping the obstacle O while it is being driven. If the obstacle O is detected, the cleaner body 10 be driven while bypassing the obstacle by driving the motor wheel 60 controls.

50 FIG. 13 is a view illustrating an obstacle avoidance driving state of the cleaner body. FIG.

When the cleaner body is driven as shown in the drawing or the driving starts from the stopped state, the obstacle O may be from the obstacle detection member 44 be recorded. The multiple obstacle detection elements 44 are on the front surface of the cover 40 provided in the curved surface shape provided. After the obstacle detection element 44 If the obstacle O which is within a predetermined angular range is detected, an obstacle avoidance driving is performed.

For example, when the obstacle O is shown by the front sensor as shown in the drawing 44c of the obstacle detection element 44 is detected while the cleaner body 10 is driven, a location of the obstacle O through the main PCB 301 or the sensing PCB 360a calculated.

And when the position of the obstacle O is calculated, the main PCB can 301 allow one of the moving wheels 60 , which are arranged on both the left and right sides, which is closer to the obstacle O, is rotated faster, whereby a traveling direction of the cleaner body 10 is changed to bypass the obstacle O.

At this point, the main PCB 301 only one of the wheel motors 632 , which are arranged on both sides, drive and can also bypass the obstacle O by setting a speed of each of the wheel motors 632 made different to each other or their direction of rotation is made different.

And the speed of each of the wheel motors 632 may be in accordance with a distance from the obstacle, that of the obstacle detection element 44 is delayed. That is, when the obstacle O is detected from a long distance, the rotational speed of the wheel motors may be increased 632 relatively slow, and if the obstacle O is detected from a short distance, the speed of the wheel motors 632 be relatively faster.

Even if, as described above, the separate operation for bypassing the obstacle O is not performed, it is possible to drive while the obstacle O through the obstacle detection element 44 actively bypassed.

In the embodiment of the present invention, the forward drive of the cleaner body 10 described. Because the second half section 313 However, also has a tilted state, the cleaner body 10 according to a change in the angle of the second half section 313 be moved backwards automatically.

51 Fig. 13 is a view illustrating a detection area of the obstacle detection element.

As shown in the drawing, the obstacle detection element detects 44 the obstacle located within a specified detection distance L For example, the obstacle detection element 44 have a detection distance of about 650 mm.

At this point, the detection distance L of the obstacle detection element 44 be set to a distance at which the ground is not detected when the cleaner body 10 is turned counterclockwise and the front wheel 312a is in contact with the ground.

If the detection distance L is too long, there is a problem that the floor can be recognized as the obstacle when the first half section 312 of the cleaner body 10 is rotated counterclockwise. In contrast, if the detection distance L is too short, the bypassing movement should be done very quickly after the obstacle that is in front of the cleaner body 10 is detected, and thus inconvenience may occur to the user, and even if the bypassing movement is performed, the obstacle can not be completely bypassed.

The obstacle detection element 44 Therefore, it may have the fixed detection distance L at which the ground is not detected when the cleaner body 10 is rotated, and the driving can be performed while the obstacle is effectively bypassed.

Because the obstacle detection element 44 meanwhile, on the front surface of the cover member 40 which is the foremost end of the cleaner body 10 is arranged, can be an emission angle of the obstacle detection element 44 be set so that the ground, even if an angle of the cleaner body 10 is changed, can not be detected, and the obstacle can be effectively detected.

When the obstacle detection element 44 for example, on a lower surface of the cleaner body 10 or provided in a low position, that of the obstacle detection element 44 light emitted does not have to be directed to the ground otherwise, and a detection error can be generated due to detection of the ground. In particular due to a characteristic of the cleaner body 10 When it is turned, it is important to select a position at which the obstacle is discriminated while the ground is not detected.

52 is a view illustrating a wall surface driving condition of the cleaner body 10 represents.

As shown in the drawing, the cleaner body 10 be moved along a wall surface of a room or furniture to perform the cleaning operation. When the cleaner body 10 moved along the wall surface, should the cleaner body 10 recognize the wall surface should be moved along the wall surface without bypassing the wall surface and should then be rotated after it has completely escaped the corner.

For this purpose, the obstacle detection element 44 be set up so that the front sensors 44b and 44c and the side sensors 44a and 44d have different detection distances L1 and L2. The detection path L1 of the front sensors 44b and 44c can be set longer than the L2 of the lateral sensors 44a and 44d , If, for example, each of the front sensors 44b and 44c has a detection distance L1 of about 650 mm, can each of the lateral sensors 44a and 44d be arranged so that it has a detection distance L2 of about 300 mm.

If the detection path L2 of each of the lateral sensors 44a and 44d the same or longer than the L1 of each of the front sensors 44b and 44c is, the wall surface is due to the detection distance L2 of each of the lateral sensors 44a and 44d too far away, and the front sensors 44b and 44c can not capture the wall surface. Finally, a situation occurs in which all of the front sensors 44b and 44c and the side sensors 44a and 44d can not detect, and thus the wall surface can not be detected. If the detection path L2 of each of the lateral sensors 44a and 44d shorter, leaving the cleaner body 10 closer to the wall surface, therefore, the front sensors 44b and 44c and the side sensors 44a and 44d recognize the wall surface at the same time.

If the front sensors 44b and 44c and the side sensors 44a and 44d meanwhile, at the same time, recognize the obstacle while the cleaner body 10 is driven, the obstacle can be considered as the wall surface, and thus the cleaner body 10 be driven without the bypass movement along the wall surface. That is, driving is performed while a state in which the front sensors 44b and 44c and the side sensors 44a and 44d recognize the wall surface, is maintained.

When the cleaner body 10 is driven continuously along the wall surface and then through the front sensors 44b and 44c the absence of the obstacle is determined and also by the lateral sensors 44a and 44d If the absence of the obstacle is determined, it is determined that the cleaner body 10 has passed a corner of the wall surface, and the cleaner body 10 can be driven in a direction of the corner.

After at this point, the absence of obstruction also through the side sensors 44a and 44d is determined, the cleaner body 10 to be moved forward a set distance and then rotated. That is, the cleaner body 10 can be rotated after it has completely passed the corner, and thus can prevent a rear portion of the cleaner body 10 collides with the wall surface.

The present invention may have various other embodiments in addition to the embodiment described above.

The remaining structure of another embodiment of the present invention, except for one part, will be the same as that of the embodiment described above, and like terms will refer to like or corresponding elements and their repeated description will be omitted.

53 FIG. 15 is a view illustrating a state in which a body part of the cleaner body is inclined forward according to another embodiment of the present invention. And 54 FIG. 13 is a view illustrating a state in which the cleaner body is tilted backward. FIG. And 55 Fig. 13 is a view illustrating a structure of a holding member according to another embodiment of the present invention.

Referring to 53 to 55 includes a cleaner body 1000 a body part 1110 , a motorbike 1120 and a battery 1130 ,

A dust container 1105 in which the through a suction unit 1160 sucked dust is stored on the body part 1110 be provided. A pair of motor wheels 1120 can each be with both sides of the body part 1110 be coupled. The battery 1130 can be separable with the body part 1110 be coupled.

A section of the cleaner body 1000 in which a connector 1103 can be adjusted, based on a straight line V, passing through a center of rotation of the moving wheel 1120 goes, as a front side are defined, and a section of it in which the battery 1130 can be defined as a back side. Likewise, the case in which the body part 1110 is turned forward, a case in which the body part 1110 on the drawing (referring to 53 ) is rotated counterclockwise, and the case where the body part 1110 is turned backwards, is a case in which the body part 1110 is rotated clockwise (referring to FIG 54 ).

The cleaner body 1000 Further, a driving part for driving the moving wheels 1120 include. And the cleaner body 1000 can drive the motion wheels 1120 by a control part according to detection information of a detection part for detecting the movement of the cleaner body 1000 Taxes.

When the detection part is in an OFF state, the movement wheels can 1120 not be driven. In this case, the body part becomes 1110 inclined according to a position of a center of gravity. When the center of gravity of the body part 1110 for example, on a front side of the straight line V passing through the turning center of the moving wheel 1120 goes, becomes the body part 1110 , as in 53 shown, tilted forward, and when the center of gravity of the body part 1110 on a back side of the straight extending line V is arranged, becomes the body part 1110 , as in 54 shown, inclined backwards.

When the detection part is turned on, the control part can drive the moving wheels 1120 control, so that the center of gravity of the body part 1110 on the straight line V passing through the center of rotation of the motor wheel 1120 goes, is arranged. In this case, a lower surface B of the body part 1110 , as in 54 also be spaced from a ground surface G.

The cleaner body 1000 may also be a rear wheel unit 1140 include. The rear wheel unit 1140 Can be on a back of the lower surface of the body part 1110 can be arranged and can serve an angle in which the body part 1110 is inclined backwards to restrict.

The rear wheel unit 1140 can also have an extension section 1144 include. An auxiliary wheel 1142 can with one side of the extension section 1144 be rotatably connected. The other side of the extension section 1144 can by a rotary shaft 1146 with the body part 1110 be rotatably connected. And the extension section 1144 can be turned up or down within a range aa '.

The rear wheel unit 1140 can also be an elastic element 1150 include. For example, the elastic element 1150 be a torsion spring. An end 1152 of the elastic element 1150 can from the body part 1110 be held, and its other end 1153 can from the extension section 1144 being held. The elastic element 1150 can apply an elastic force, so that the extension section 1144 is rotated clockwise on the drawing.

If the body part 1110 is tilted to the maximum forward, a front portion of the lower surface B of the body part 1110 be in contact with the ground surface G. Thus, a maximum forward rotation angle of the body part 1110 be limited.

If the body part 1110 on the other hand, the rear wheel unit can 1140 be in contact with the ground surface G. Consequently, a maximum backward rotation angle of the body part 1110 be limited. Therefore, the body part can be prevented 1110 is tilted forward or backward.

The lower surface B of the body part 1110 may form a predetermined angle θ with respect to the ground surface G when the body part 1110 maximally inclined backwards. At this point, the angle θ between the lower surface B of the body part 1110 and the ground surface G be about 17 ° to 20 °.

A cover 1131 can on the battery 1130 be provided. While the battery 1130 on the body part 1110 installed, the cover may be 1131 to the outside. Therefore, the cover 1131 at least part of the body part 1110 form. Likewise, the user can use the battery 1130 with the body part 1110 connect / disconnect from it, without the body part 1110 disassemble.

Here below is a procedure in which the battery 1130 on the body part 1110 installed or disconnected from it, described in detail. However, the following descriptions are limited to the cases where the center of gravity of the body part 1110 is located on the front when the battery 1130 from the body part 1110 is separated, and the center of gravity of the body part 1110 is located on the back when the battery 1130 with the body part 1110 is coupled.

56 FIG. 14 is a view illustrating in sequence a method in which a battery is coupled to the cleaner body. FIG.

56A is a view illustrating a state in which the battery 1130 from the body part 1110 is separated, and 56B is a view illustrating a state in which the battery 1130 with the body part 1110 is coupled, and 56C is a view illustrating a state in which the body part 1110 is inclined backwards.

A battery coupling section 1107 with which the battery 1130 is coupled to the body part 1110 educated. The battery coupling section 1107 can by eliminating part of the body part 1110 be educated.

The battery coupling section 1107 is on a bottom of the body part 1110 trained, and thus the battery 1130 with the underside of the body part 1110 coupled. While the battery 1130 for example on the body part 1110 is installed, the center of gravity of the battery 1130 on a lower side than the turning center of the moving wheel 1120 be arranged.

Because the center of gravity of the battery 1130 can be moved down when the battery 1130 with the body part 1110 coupled, therefore, the driving stability of the cleaner body 1000 be improved.

When the battery 1130 with the underside of the body part 1110 coupled, there is an advantage that the driving stability of the cleaner body 1000 is improved. Because the battery 1130 however, with the underside of the body part 1110 should be uncomfortable for the user, the battery 1130 to dock.

While the battery 1130 from the body part 1110 is separated, the center of gravity of the body part 1110 however, on a front side of the straight line extending through the center of the motion wheel 1120 goes, be arranged. When the battery 1130 from the body part 1110 is separated, the body part can 1110 therefore, the movement wheel 1120 be tilted forward.

If the body part 1110 is inclined, the front portion of the lower surface of the body part comes 1110 in contact with the soil surface. At this point, the battery coupling section becomes 1107 directed diagonally upwards. Therefore, the user can use the battery 1130 easy to connect.

The battery 1130 can by a coupling guide portion, which at the battery coupling portion 1107 is provided in an oblique direction with respect to the body part 1110 be coupled. In particular, an insertion direction S of the battery 1130 form an acute angle respectively with respect to the straight line V and also the bottom surface. When the front portion of the lower surface of the body part 1110 therefore, in contact with the ground surface, the insertion direction S of the battery forms 1130 the acute angle with respect to the ground surface.

When the battery 1130 with the body part 1110 coupled, the center of gravity of the body part 1110 be moved backwards. That is, while the battery 1130 with the body part 1110 coupled, the center of gravity of the body part 1110 on the back of the straight line extending through the center of the motor wheel 1120 goes, be arranged.

When the battery 1130 in other words with the body part 1110 coupled, the body part 1110 around the movement wheels 1120 be inclined backwards. At this point is the rear wheel unit 1140 optionally in contact with the soil surface. At this point, the lower surface B of the body part forms 1110 a predetermined angle θ with respect to the ground surface G.

57 FIG. 14 is a view illustrating a process in which a battery is separated from the cleaner body in order. FIG.

In particular, presents 57A a condition before the battery 1130 from the body part 1110 is disconnected, and 57B represents a condition in which the battery is discharged from the body part 1110 is disconnected.

To the battery 1130 from the body part 1110 To disconnect, the user can directly apply a force to the body part 1110 apply and can the body part 1110 tilt forward. Then the user can use the battery 1130 in a direction opposite to the insertion direction S separate.

When the battery 1130 from the body part 1110 is the center of gravity of the body part 1110 moved back to the front. Therefore, the body part 1110 be kept in a forward tilted state.

As described above, in the vacuum cleaner of the present invention, the battery 1130 on the body part 1110 is installed, the body part can 1110 be rotated backwards, and thus the lower surface of the body part 1110 be spaced from the ground surface. That is, the body part 1110 can when driving through the movement wheels 1120 be stored on two points. In this case, the cleaner body 1000 easier to climb over an obstacle, and as the driving friction on the moving wheels 1120 acts, can be reduced, a worker, which is required when the user cleans the body 1000 moved, also be reduced.

When the battery 1130 from the body part 1110 is the center of gravity of the body part 1110 moving forward, and the body part 1110 is rotated forward, and thus the battery coupling portion 1107 lying on a back bottom of the body part 1110 is provided, moved upwards. Consequently, the user can use the battery 1130 easily with the battery coupling section 1107 couple.
